I.       INTRODUCTION  



                                                                                                                      

                   An elementary school nurse who unsuccessfully attempted to save the life  



                                                                                                                      

of a choking child soughtworkers' compensation benefits for mental health problems she  



                                                                                                              

attributed to the incident.  She argued that she suffered post-traumatic stress disorder  



                                                                                                                       

(PTSD) due to exposure to the child's bodily fluids and resulting risk of disease and to

the mental stress of the incident.  The Alaska Workers' Compensation Board denied her  



                                                                                                                           

claims, concluding that her exposure to bodily fluids was not a sufficient physical injury  



                                                                                                                              

to trigger a presumption of compensability and that the mental stress of the incident was  



                                               

not sufficiently extraordinary or unusual to merit compensation.  The Board was most  



                                                                                                                           

persuaded by the opinion of the employer's medical expert that the nurse's mental health  



                                                                                                                          

problems were the result of a pre-existing mental health condition and were not caused  



                                                                                                                    

by the incident.  The Alaska Workers' Compensation Appeals Commission affirmed.  



                                                                                                                           

                    We note two errors in the Board's analysis but ultimately affirm the denial  



                                                                                                                              

of benefits.  The Board failed to recognize the link between exposure to bodily fluids and  



                                                                                                                                 

mental distress over the risk of serious disease, which under our precedent is enough to  



                                                                                                                           

establish a presumption that the mental distress is compensable.  The Board also failed  



                                                                                                                            

to consider the particular details of the child's death and the nurse's involvement when  



                                                                                                                                 

it concluded as a general matter that the stress of responding to a choking incident at  



                                                                                                                              

school is not sufficiently extraordinary to merit  compensation for mental injury.  But  



                                                                                                                               

because the Board found in the alternative that the incident was not the cause of the  



                                                                                                                            

nurse's mental health problems, and because both the Commission and this court must  



                                                                                                                  

respect  the  Board's  credibility  determinations  and  the  weight  it  gives  conflicting  



                                 

evidence, we affirm.  



                                  

II.       FACTS AND PROCEEDINGS  



                                                                                    

          A.        The Choking Incident And Immediate Aftermath  



                                                                                                       

                    In September 2014 Shannon Patterson worked for the Matanuska-Susitna  



                                                                                                                               

Borough School District as an elementary school nurse.  One day children ran into her  



                                                                                                                               

office screaming because a child was choking on his lunch.  Patterson ran to assist the  



                                                                                                                          

child, who was turning blue when she arrived. Patterson tried to clear the child's airway  



                                                                                                                             

and helped perform CPR until emergency medical personnel arrived and rushed the child  



                                                                                               

to the hospital.  The child later died as a result of the choking incident.  



                                                             -2-                                                           7635
  


----------------------- Page 3-----------------------

                  Because  Patterson had been exposed to the child's bodily  fluids, she had  



medical  tests  to  screen  for  serious  diseases  shortly  after  the  incident;  her  results came  



back   negative.    The   District   reported   the   injury   to   the   Board,   indicating   it   affected  



"multiple   body   parts,"   with   the   cause   of   injury   shown   as   "absorption,   ingestion   or  



inhalation."   The District paid Patterson temporary total disability benefits for about three  



months.   Patterson's  doctors  wrote  notes  excusing  her  from  work  because  of  "on-site  



trauma"  and  "situational  stress."  



                  Patterson  sought  counseling  shortly  after  the  incident.   Patterson's  doctors  



initially  diagnosed  her  with  adjustment  disorder,  later  changing  her  diagnosis  to  include  



PTSD.  



                  In   December   2014   the   District   required   Patterson   to   be   evaluated by   a  



psychiatrist,  Dr.  David  Glass.   Dr.  Glass  did  not  think  Patterson  had  any  ongoing  mental  



health  concerns  related  to  work.   He  diagnosed  a  non-work-related  mood  disorder.   He  



did  not  diagnose  a  personality  disorder,  but  he  noted  that  "personality  psychodynamics  



and   psychosocial   factors  are   involved   with   Ms.   Patterson's   symptoms."     Dr.   Glass  



thought  Patterson's  main  problem  was dissatisfaction  with  working  as  an  elementary  



school   nurse,   an   occupational   problem   rather   than   a   mental   health   problem.     He  



concluded  that  any  ongoing  mental  health  problems  were  not  work  related,  that  she  was  



medically   stable,   and  that   she   was   able   to   return   to   work   as   a   school   nurse.     He  



acknowledged   that   the   choking   incident   would  be   "quite   distressing"   but   thought  



Patterson  could  have  dealt  with  the  distress  and  returned to  work  after  a  few  sessions  



with  her  counselor.   When  asked  his  opinion  as  to  whether  the  work  stress  caused  by  the  

choking  incident  was  extraordinary  and  unusual,1  Dr. Glass allowed that the "tragedy"  

                                                                                                          



         1        When  an  employee  makes  a  mental  stress  claim,  AS  23.30.010(b)  requires,  



among   other   things,   proof   that   "the   work   stress  was  extraordinary   and   unusual   in  

                                                                                                    (continued...)  



                                                       -3-                                                     7635

might  be  unusual  in  that  it  was  "not  a  common  occurrence,"  but  he  thought  "aspiration  



crises  with  small  children"  would  not  be  unusual  events  for  a  school  nurse.   The  District  



controverted  benefits  based  on  Dr.  Glass's  report.  



                 In  February  2015  Patterson returned  to  work, in line with recommendations  



of  her  counselor,  Dr.  Kevin  O'Leary,  and  her  treating  physician,  Dr.  Duane  Odland.   She  



returned  in  a  school  nurse  position  that  sent  her  to  different  schools  as  needed.  



         B.      Patterson's  Claims  For  Disability  Benefits  



                 Patterson, representing herself, filed  her  first  written workers' compensation  



claim   in   February   2015,   seeking  temporary   total   disability   benefits   for   one   month,  



temporary partial disability  benefits starting in early  February, medical and transportation  



costs,   and   a   second   independent   medical   evaluation   (SIME).     The   claim   identified  



"[e]xposure   to   possible   blood   born[e]   pathogens/unknowns   .   .  .   and   post   incident  



emotional   stress,   anxiety,   grief   &   depression"   as   the   type   of   injury;   she   noted   her  



"mouth,  nose,  face,  hair,  hands,  lungs  and  blood  stream"  and  "[m]ind"  as  the  body  parts  



injured.    The  District   answered,   admitting  it  had  paid  temporary  total  disability   for   a  



period  of  time  and  denying  it  was  liable  for  further  payments.  



                 Patterson   had   a   contract with   the   District   for   the   2015-16   school   year,  



working  as  a  nurse  at  another  elementary  school.   Patterson  declined  an  offer  to  renew  



her   contract   with  the   District   for   the   2016-17   school   year   because   she   thought   -  



incorrectly   as   it   turned   out   -   that   her   retirement   benefits   had   already   vested.    She  



submitted a  resignation  email  on  May   17,  2016.   The  following  month  Patterson,  still  



representing  herself,  filed  an  amended  claim  for  workers'  compensation.   In  this  claim  



she  identified  her  "Psyche"  as  the  injured  body  part  and  "PTSD,  Anxiety,  Depression"  



         1       (...continued)  



comparison  to  pressures  and  tensions  experienced  by  individuals  in  a  comparable  work  

environment."

as  the  illness  or  injury.   She  claimed  her  symptoms were  aggravated  by  continuing  to  



work  as  a   school  nurse.   Until  this  time  Patterson  had  been   seeing  Dr.  O'Leary,  who  



believed  she  continued  to  suffer  from  PTSD.   But  their  treatment  relationship  ended  in  



the  summer  of  2016.  



                 Attorney  Richard  Harren  entered  an  appearance  before  the  Board  on  behalf  



of   Patterson   in   late   July   2016.    In   early   2017   Harren   filed   a  petition that included   a  



request  for  an  SIME  and  review  of  discovery  disputes  but  did  not  then  file  the  forms  the  

Board  requires  when  requesting  an  SIME.2  



                 Patterson  was  referred  to  a  psychologist,  Dr.  Paul  Wert,  for  an  evaluation  



in  late  April  2017.   Dr.  Wert  diagnosed  PTSD,  depression,  and  an  anxiety  disorder;  he  



additionally  noted  "[d]ependent,  avoidant  (socially),  and possibly borderline personality  



features  or  traits."   The  evaluation  was  filed  with  the  Board  in  May  2017,  and  at  the  end  



of  June  Patterson  requested  a  hearing  on  her  written  claims.   The  District  opposed  setting  



a  hearing  because  discovery  was  ongoing.  



                 Patterson  deposed  Dr.  Jay  Johnson,  a  former  employer  who  had  provided  



her   medical   care.    Dr.   Johnson   was   retired   but   had   practiced   psychiatry   in   Alaska,  



treating  children  and  adolescents.   He  agreed  with  Dr.  Wert  that P           atterson  had  PTSD.   



Dr.  Johnson thought the choking incident  had left  Patterson  continually  anxious  about  



another  episode,  although  he  acknowledged  Patterson  had  life-long  anxiety.   He  testified  



that  the  child's  death  would  be  extraordinary  and  unusual  stress  for  a  school  nurse.   He  



said he  had  experienced patients' deaths  when  he  was  practicing  as a  pediatrician  and  



described  it  as  "a  horrible  feeling."

                    In June 2017 Patterson began to  see another counselor, Debra Haynes.  



                                                                                                               

Haynes diagnosed Patterson with PTSD, noting Patterson had a "startle response" and  



                                                                                       

reported waking with nightmares two or three times per week.  



                                                                                                                                   

                    In late August 2017 the parties attended a prehearing conference to set a  



                                                                                                                            

time for a hearing.  There Harren confirmed that Patterson no longer believed an SIME  



                                                                                                                      

was necessary.  After scheduling a hearing on a trailing calendar, the parties stipulated  



                                                                                                                     

to specific deadlines, including filing evidence by December 27, 2017, and attorney's  



                                                        

fees affidavits by January 10, 2018.  



                                                                                                                             

                    The District scheduled another medical evaluation in late October 2017  



                                                                                                         

with a different doctor, Dr. Keyhill Sheorn.  The written evaluation was not signed by  



                                           

Dr. Sheorn until December 23; it was served on Patterson and filed with the Board on  



                                                                                                                    

December 26.  Dr.  Sheorn's evaluation had a new diagnosis:  borderline personality  



                                                                                                                       

disorder with "strong elements of Histrionic Personality Disorder." Dr. Sheorn disagreed

disorders.         Dr.  Sheorn  did  not  think  Patterson  had  PTSD  but  thought  she  was  



                                                                                                                              

malingering and opined that Patterson had no functional limitations preventing her from  



                                                                                                                              

continuing to work as a nurse.  Dr. Sheorn attributed any need for therapy resulting from  



                                                                                                                                

the incident to Patterson's "maladaptive ways of coping with stress" connected to her  



                                                                                                                            

"underlying mental illness."  Patterson did not ask for either a continuance or an SIME  



                                                         

related to Dr. Sheorn's report at that time.  



                                                                                          

                    Patterson filed both her hearing exhibits and her attorney's fees affidavit  



                                                                                                                      

one day late, prompting the District to petition to strike them.  After hearing testimony

exhibits' filing, but it refused to accept the attorney's fees affidavit because it determined  



                                            

Harren had a pattern of late filings.

           C.        The Board's Hearing On Patterson's Claim  



                                                                                                                      

                     When the hearing began  at  11:10 a.m. on the  scheduled day, Patterson  



                                                                                                                               

asked the Board to delay it a day to allow for a full-day hearing.  The Board panel was  



                                                                                                                               

not able to accommodate a one-day delay but agreed to stay an hour late.  Patterson was  



                                                                                                                                

allotted three and a half hours of time, with the District given two and a half hours.  No  



                                                                                                                     

one objected, and Harren indicated that he wished to finish the hearing that day.  



                                                                                                                               

                     Patterson presented several lay witnesses, Dr. Wert, and Haynes, who was  



                                                                                                                           

still treating her.   She also presented testimony from  Susan Magestro, whose  expert  



                                                                                                                                

qualifications and testimony were  disputed.   Dr. Wert testified  consistently with his  



                                                                                                                                

report.  The Board chair asked Dr. Wert detailed questions about the various criteria for  



                                                                                                                         

PTSD, seeking specific examples of how Patterson met those criteria. Dr. Wert testified  



                                                                                            

that he did not think Patterson had a borderline personality disorder.  



                                                                                                                                      

                     The District disputed Magestro's qualifications to offer certain opinions.

                    The District's only witness was Dr. Sheorn, who had listened to the hearing.  



                                                                                                                                 

Dr. Sheorn's testimony was consistent with her report but also included responses to  



earlier witnesses' testimony.  She gave the opinion that Patterson met few of the eight

incident was insufficiently severe to trigger PTSD, she thought Patterson failed to meet  



                                                                                                                               

most of the other criteria.  For example, Dr. Sheorn pointed out that Patterson did not  



                                                                                                                             

avoid thinking or talking about the incident.  Dr. Sheorn explained in broad terms why  



                                                                                                                  

she  thought  Patterson  had  a  personality  disorder,  and  she  opined  that  Patterson's

incident.

apparent that the parties disagreed about the nature of Patterson's claim; the Board said  



                                                     

it would deal with this issue in its decision.

weight  to  Dr.  Sheorn's  opinion  that  Patterson's  counseling  needs  stemmed  from  a  pre- 



existing  personality   disorder,  not  PTSD.   The  Board  gave  little  weight  to  Dr.  Wert's  



PTSD   diagnosis,   although   it   appeared   to   credit   his   observations   about   Patterson's  



personality  traits  that  it  described  as  "suggestive  of  borderline  personality."   The  Board  



found   Patterson's   testimony   that   she   loved   working   as   a   school   nurse   and   her  



explanations  for  why  she  stopped  working not c   redible.   The  Board  did  not  explicitly  



assign  weight  to  either  Dr.  Johnson's  testimony  and opinions or  Dr.  O'Leary's diagnosis.   



The  Board  denied  all  of  Patterson's  claims.  



                  Patterson   filed   a   timely   appeal   to the   Commission.    In   early   July   2019  



Patterson  filed  a  petition  for  an SIME  with  the  Board  along  with  the  necessary   SIME  



paperwork  and  a  motion  to  stay  the  Commission  appeal  due  to  her SIME petition  with  



the  Board.   The  Commission  stayed  the  appeal  and  returned  jurisdiction  to  the  Board  for  



consideration   of   the   SIME   petition.     After   a   hearing   the   Board   denied   the   petition  



because  it  was  untimely  and  because  the  Board  did  not  find  an  SIME  would  have  been  



helpful.     Patterson   filed   an   appeal   of   the   SIME   denial,   which   the   Commission  



consolidated   with   the   original   appeal.     Patterson's   brief   to  the   Commission   made  



numerous   arguments,   some   of   which   the   Commission   did   not   directly   address.    The  



Commission  subsequently  affirmed  both  Board  decisions.   Patterson  now  appeals  to  us.

 IV.	      DISCUSSION  



                    Patterson sought compensation for mental injuries that she alleged stemmed  

                                                                                                                       



from the choking incident.   The Alaska Workers'  Compensation Act requires mental

mental injury is a physical injury or mental stress.6  It appears from the record that neither  

                                                                                                                          

                                                                 

the Board through the prehearing process7 nor the parties through their pleadings clarified  

                                                                                                                        

                                                   



prior to the hearing the type of mental injury claim Patterson was making.  In its decision

facts of the case.  Patterson's appeal presents arguments related to each type of claim, as  

                                                                                                                                 



well as procedural arguments pertaining to the entire proceeding.

First,  the   employee   attaches a  presumption  that  the   claim  is  compensable  by   showing  



some  evidence  of  "a  causal  link"  between  the  work  and  the  disability  or  need  for  medical  

treatment.9  Second, the employer may rebut the presumption by presenting substantial  



                                                                                                                   10  

evidence  that  the  disability  or  need  for  medical  treatment  was  not  work  related.                           If  the  



employer  does  so,  then  at  the  third  step  the  Board  must  weigh  the  evidence  and  determine  



whether  employment  was,  in comparison with  other  causes  of  the  disability  or  need  for  

medical  care,  "the  most  important  or  material  cause  with  respect  to  the  benefit  sought."11  



                   The   Board denied   Patterson's   physical-mental   claim   at   each   step   of   the

           12        The Board also concluded that Patterson waived her physical-mental claim

evidence  at  the  third  step,  noting  that  the  Board's  credibility  determinations  are  binding  

on  the  Commission.13  



                   In  her  opening  brief  Patterson  challenged  (1)  the  Board's  determination  that  



she   did   not   attach   the   presumption   of   compensability   and   (2)   the   Commission's  



conclusion that substantial evidence supported  the  Board's decision.  In her reply brief  



Patterson  argues  for  the  first  time  that  the  District  did  not  rebut  the  presumption,  but  she  

waived  that  argument  by  failing  to  raise  it  in  her  opening  brief.14  

                                                                                             The  District  maintains  



that  all  of  the  different  legal  analyses  the  Board  engaged  in  were  correct.  



                   1.	       Patterson's  exposure  to  bodily  fluids  was   a  sufficient  injury  to  

                             attach   the   presumption   of   compensability   for   a   "physical- 

                             mental"  claim.  



                   Patterson   contends her   contact   with   the   child's   bodily   fluids   during   her  



attempts  at  resuscitation  was a     physical  injury that  caused  her  mental  health  problems.   



The Board  decided  Patterson  had  not  attached  the presumption  of compensability because  



the   tests   for   blood-borne   illnesses   were   negative,   meaning   she   "did   not  sustain  an  



occupational   disease   or   infection"   from   the   exposure.    The   Commission   inaccurately  



           13       AS   23.30.128(b)   ("The   [B]oard's   findings   regarding   the   credibility   of

stated  that  the  Board  accepted  her  exposure  as  adequate  to  attach  the  presumption and  



then  affirmed  what  it  described  as  the  Board's  ruling.  



                    Exposure  to  bodily  fluids  can  be  the  basis  for  a  physical-mental  claim,  even  



if  the  claimant  does  not  contract  any  disease,  because  the  risk  of  getting  sick  may  cause  



mental   stress.     In   Runstrom   v.   Alaska   Native   Medical   Center   a   healthcare   worker  



developed  a  mental  health  condition  after  being  splashed  in  the  eye  by  an  HIV-positive  



                       15  

patient's  blood.          She  never  acquired  HIV  but  she  underwent  testing  for  it  and  received  



                                      16  

antiretroviral  medication.               She  later  made  a  claim related  to  a  mental  health  disorder,  and  



we  agreed  with  the  Commission  that  her  claim  was  a  physical-mental  claim  because  her  



mental   condition   was   the   result   of   a   physical   injury   -   the   eye   splash  and  disease  



               17  

exposure.          



                    We  recognized  in  Runstrom  that  the  exposure  to  bodily  fluids  itself,  which  



we  described  as  a  "physical  injury,"  had  a  clear  link  to  mental  injury:   being  splashed  with  



blood was "undoubtedly  frightening  after  [Runstrom]  realized  she  had  been  exposed  to  

                                        18   The link between exposure to disease through bodily fluids  

a  potentially  fatal  disease."                                                                                           



and mental injury exists here too.  Patterson, like Runstrom, was exposed to bodily fluids  

                                                                                                                           



in  a  way  that  necessitated  testing  for  serious  diseases.                        Runstrom  was  treated  with  

                                                                                                                            



medication pending the  outcome of her tests  and Patterson was not, but the need  for  

                                                                                                                              



medication was not central to Runstrom's holding.  Instead the link was based on fear of  

                                                                                                                                



contracting a serious disease.  In Runstrom the risk that exposure to bodily fluids would

indication  that  the  child  to  whose  bodily  fluids  she  was  exposed  had  any  communicable  



              19  

diseases.           But   for   purposes   of   attaching   the   presumption  of   compensability,   that  



difference  is  not  material.   



                     The   Board's   decision   failed   to   apply  Runstrom   correctly,  but   the   Board  



alternatively   found,   after   weighing   all   the   evidence,   that   Patterson's   exposure   to   the  



child's   bodily   fluids   was   not   the   substantial   cause   of   her   mental   injury,   and   the  



Commission affirmed this  finding.  Because we decide  that  the  Commission's decision  



on  the  merits  of  this  claim  was  correct,  the  Board's  error  about  attaching  the  presumption  

was  harmless.20  



                     2.	       The   Commission   did   not   err   by   concluding   that  substantial  

                               evidence   supports   the   Board's   determination   that   Patterson's  

                               physical   injury   was   not   the   substantial   cause   of   her   mental  

                               health  condition.  



                    After  deciding  in  the  alternative  that  the  District  rebutted  the  presumption,  



the  Board  weighed  the  evidence  and  denied  Patterson's  claim because it  gave most  weight  



to  Dr.  Sheorn's  opinion  that  Patterson's  mental  health  problems  were  attributable  to  her  



pre-existing   mental   illness,   not   to   the   choking   incident.     The   Commission   affirmed,  



deferring to  the  Board's  determination  of  witness credibility.   Patterson  argues  that  the  



Board's  reliance  on  Dr.  Sheorn's  opinion  was  error  largely  by  contending  that  Dr.  Sheorn  



was  improperly  biased.  



                     The  Act g     ives  the  Board  "the  sole  power  to  determine  the  credibility  of  a  



witness"   and   provides   that   the   Board's   finding   about   "the   weight   to   be   accorded   a

witness's testimony, including medical testimony and reports, is  conclusive even if  the  



                                                                                        21  

evidence  is   conflicting   or   susceptible  to   contrary   conclusions."                The  Board gave  the  



most  weight  to  Dr.  Sheorn's  diagnosis  and  opinions,  which  supported  the  conclusion  that  



Patterson  did  not  have  a  work-related  mental  health  condition.   The  Board  also  correctly  



found   that   Dr.   Wert's opinion   did   not   support   the   physical-mental   claim   because   he  



"attributed  the  [PTSD  diagnosis]  to  [Patterson's]  exposure  to  actual  or  threatened  death,"  



not  to  her "exposure to the  student's  bodily  fluids."   Because  the  Commission  is  bound  



by the  Board's  weighing  of  the   evidence,  it  did  not   err  by  concluding  that   substantial  



evidence  supported  the  Board's  decision  to  reject  the  physical-mental  claim.  



         B.	      The   Commission   Did   Not  Err   By   Affirming   Denial   of   Patterson's  

                  "Mental-Mental"  Claim.   



                  The   Act   establishes   a   distinct   framework   for   compensation   for   mental  



injuries   allegedly   caused   by   work-related   mental   stress,   also   called   "mental-mental"  

claims.22  

              Under  AS  23.30.010(b),  workers'  compensation  is   "not  payable  for  mental  



injury   caused   by   mental   stress,   unless   it   is   established   that   (1)   the   work   stress   was  



extraordinary   and   unusual   in   comparison  to   pressures   and   tensions   experienced   by  



individuals   in   a   comparable   work   environment;   and   (2)   the   work   stress   was   the  



                                                        23  

predominant  cause  of  the  mental  injury."               



                  The Board  denied  Patterson's  mental-mental claim on both grounds,  finding  



that  the  stress  of  the  choking incident was not  "extraordinary and  unusual"  and  that  the

          23        The statute also provides  that  the amount  of  stress  must  "be  measured by  



 actual  events,"  and  a  mental  injury  is  not  compensable  if  it  "results  from  a  disciplinary  

 action,  work   evaluation,  job  transfer,   layoff,   demotion,  termination,   or   similar   action  

 taken  in  good  faith  by  the  employer."   AS  23.30.010(b).

stress was not the predominant  cause of  her  mental health condition.  The Commission  



affirmed  both  of  these  rulings.   Although  the  agencies'  analysis  misapplies  our  precedent  



on   mental  stress   -   which   the   District   does   not   defend   -   we   affirm   the   denial   of  



Patterson's  mental-mental  claim  because  the  Commission  did  not  err  by  concluding  that  



substantial  evidence supports  the  Board's  finding  that stress  from  the  choking  incident  



was  not  the  predominant  cause  of  Patterson's  mental  injury.  



                   1.	       The   agencies   erred   in   analyzing   Patterson's   claim   of   mental  

                            stress  by  failing  to  consider  particular  details  about  the  severity  

                            of  the  incident.   



                   In  Kelly  v.  State,  Department  of  Corrections  we  reversed  the  rejection  of  a  



                                                                   24  

mental-mental  claim  brought  by  a  prison  guard.

threatened to stab the guard in the eyes and then kill him. 



was  afraid  to  provoke  the  inmate  by  calling  for  help,  so  he  remained  in  the  standoff  until  



                                                                                                                  26

                   The  Board  denied  the  guard's  mental-mental   claim,   finding  the   stress  he  



experienced  was not unusual   and   extraordinary.    The   Board  reasoned   that   it  was  not  



unusual  for  prison  guards to be threatened by inmates, relying on testimony by another

"viable"  to  that  guard.          The  Commission  affirmed.                 



                   We  reversed  because  the  agencies'  analysis  of  the  claimant's  stress   was  too  



generalized:   "An  examination  of  [the  other  guard's]  testimony  shows  that  while  he  had  



experienced  threats,  they  were  of  a  different  quality  and  character  from  the  death  threat  

incident  that  Kelly  described."29  

                                               The  failure  to  consider  the  particular  facts  of  the  incident  



                                                                                    30  

in  evaluating  the  degree  of  mental  stress r   equired  reversal.                   We  made  it  clear  that  the  



Board  must  consider  the  particular  facts  and  key  details  to  determine  whether  the  stress  



related  to  an  incident  is  extraordinary  and  unusual.  



                   The  Board's  and  Commission's  decisions  in  this  case  essentially  make  the  



same  mistake  as  in  Kelly  by  considering  the  choking  incident  at  a  high  level  of  generality,  



without   attention  to  key   details.    The  Board   focused   on  the  need for school  nurses  to  



respond  to  emergencies  and  the  frequency  of  choking  in  elementary  schools.   The  Board  



also   noted   evidence   that,   in   the   year   following  the   choking   incident,   Patterson   was  



involved   in   two   more   emergencies.    It   therefore   concluded   that   emergencies   were  



common  enough  in  her  line  of  work  that  the  choking  incident  underlying  her  claim  could  



not  be  considered  extraordinarily  or  unusually  stressful.  



                   Neither  the  Board  nor  the  Commission  considered  the  quality  and  character  



of  the  specific  choking  event  that  underlay  Patterson's  claim.   Just  as  not  all  threats  to  



prison   guards   are   equally   stressful,  not   all   emergency   care   in   an   elementary   school   is  



equally stressful.  The September 2014 incident involved a child who was turning blue

----------------------- Page 18-----------------------

by  the  time  Patterson  was able  to attend to him,  lost  his  pulse  multiple  times  during  her  



efforts to  revive him, required emergency transport to the hospital,  and later  died.  The  



Board  discussed  none  of  these  factors  when  evaluating  whether  Patterson's  stress  could  



be   extraordinary   and   unusual in   comparison   to   the   stress   commonly   experienced   by  



school  nurses.  



                   The Board  also failed to  acknowledge evidence in the record highlighting  



the   severity   of   the   incident.    It   mentioned   one   part   of   Dr. Glass's   report,   apparently  



considering   his    statement   that   "aspiration    crises   with    small  children"   were   not  



"extraordinary   or   unusual,"   while   failing   to   mention   his   acknowledgment   that   the  



"tragedy   in   September   could   be   considered   unusual   -   fortunately   not   a   common  



occurrence"  and  that  "the  event  [was]  emotionally  traumatic."   Nor  did  the  Board  mention  



Dr.   Sheorn's   concession that   the   incident   could   have   been   severe   enough   to   trigger  

PTSD31  or the testimony of Dr. Johnson, the only medical provider who testified from  

                                                                                                                         



personal  experience about the effect of a young patient's  death, that the incident was  

                                                                                                                          



"extremely unusual" and would require counseling.  

                                                           



                   As for the other examples of emergency care by Patterson that the Board  

                                                                                                                       



highlighted, neither of those incidents involved a person's death, nor was Patterson so  

                                                                                                                            



intimately involved in providing care.  The outcome of a later choking incident was that  

                                                                                                                           



the child's teacher "did abdominal thrusts and cleared" the obstruction while Patterson  

                                                                                                                  



"sprinted" to the classroom, so Patterson did not provide emergency care herself.  During  

                                                                                                                      



a staff member's collapse, Patterson was "ready to use the [defibrillator] and begin CPR"  

                                                                                                                        



but again was not actually required to provide emergency care.  

                                                                                      



           31        As  set  out  in  Dr.  Sheorn's  report,  this  criterion  requires  that  the  person  be  



 "exposed  to:   death,  threatened  death,  [or]  actual  or  threatened  serious  injury"  by,  among  

 other  things,  witnessing  it  in  person.

----------------------- Page 19-----------------------

                   Finally,  the  Board's   attempt  to  distinguish  Kelly,  which  the   Commission  



approved,  is  misplaced.   The  Board  distinguished  Kelly  by  noting  that  the  guard  had  been  



"subjected  to   a  traumatic   death  threat,"  whereas  Patterson "was not  threatened."   But  



mental  stress  can  result  from  many  different  situations,  not j  ust s   ituations i  n  which  the  



claimant  is  threatened  by  another  person.   Our  decision in  Kelly  certainly  did  not  imply  



that  mental-mental  claims  are  compensable  only  if  they  arise  out  of  being  threatened.  



                   All  told,  the  agencies'  legal  analysis  of  whether  Patterson's  work  stress  was  



sufficiently extraordinary and unusual to support a mental-mental claim was erroneous  



                                             32  

in  light  of  our  decision  in  Kelly.  



                   2.	      The   Commission   did   not   err   by   determining   that   substantial  

                            evidence  supported  the  Board's  finding  that  the  mental  stress  of  

                            the    choking    incident    was    not    the    predominant    cause    of  

                            Patterson's  mental  injury.   



                   The  agencies'  error  in  considering  whether  the  stress  Patterson  experienced  



was  extraordinary  and  unusual  is  troubling  but  ultimately  harmless  because  substantial  



evidence   supports   the   Board's   alternative   conclusion   that  the   stress   was   not   the  

predominant   cause   of   Patterson's   mental   injury,33  

                                                                           which   the   Commission   affirmed.   



Patterson  argues  that  the  Board  erred  in  relying  on  Dr.   Sheorn's  report and  testimony,  



citing  research  about  Dr.  Sheorn's  testimony  in  other  cases.  



           32       The   Commission's  decision   cites   Kelly   as   saying   that   the   employee's  



 "perception  that   she   feels   stress   is   inadequate  to   establish   extraordinary   and  unusual  

 stress."    In  Kelly   we  held   that   "a  worker's  perception  that  he   feels   stress is by   itself  

 inadequate  to  establish"  that  level  of  stress.   218  P.3d  at  299-300  (emphasis  added).   We

                  As  explained  above,  the  Board  has  the  sole  authority  to  weigh  evidence  and  



                              34                                                                              35  

determine   credibility,          and  the   Commission   is  bound  by  those   determinations.                   The  



Board  evidently  was  not  persuaded  by  Patterson's  assertion  that D                   r.  Sheorn  had  a  bias  



that  made  her  opinions  unreliable,  and  neither  the Commission nor this  court  has authority  

to   second-guess   the   Board   on   that  point.36  

                                                              Therefore   the   Commission   did  not   err  by  



affirming  the  Board's  denial  of  Patterson's  mental-mental  claim.   



         C.	      The  Commission  Did  Not Err By Affirming The  Board's  Denial  Of  A  

                  Second  Independent  Medical  Evaluation.  



                  Patterson  asked  the  Board  to  order  a  second  independent  medical  evaluation  



(SIME)  months  after  the  Board  had  issued  a  final  decision  in  her  case,  while  it  was  on  



appeal  to  the  Commission.   The  Commission  stayed  the  appeal  and  returned  the  case  to  



the   Board   so   the   Board   could   consider   the   petition.    The   Board   denied   the   petition,  



concluding  that  under  its  regulations  the  request  was  untimely  and  that  an  SIME  would  



not  have  been  helpful  in  any  event.   The  Commission  affirmed  the  Board's  decision.  



                  On  appeal  Patterson  argues,  as  she  did  in  the  Commission,  that  the  Board's  

failure  to  order  an  SIME  violated  her  due  process  rights.37  

                                                                                  She  maintains  that  an  SIME  



was  required  to  counter  Dr.  Sheorn's  report,  which  she  considers  "very  biased."   But  she  



          34       AS  23.30.122.  



          35       AS  23.30.128(b).

 2020)  (affirming  decision  that  gave  more  weight  to  an  expert  whom the  Board  had  found  

 not  credible  in  other  cases  because  of  Board's  authority  to  weigh  evidence).  



          37        The Commission did not discuss Patterson's due process claim.

fails  to  develop  a  legal  argument  why  due  process  limits  the  Board's  discretion  to  reject  

such  a  late  SIME  request  and  thus  has  waived  that  claim.38  



                   The   statutory  language   of   AS   23.30.095(k),   the   subsection   authorizing  



                                                                                                      39  

SIMEs,   indicates   that   the   Board   has   discretion   to   order   an   SIME.                        The   Board's  



regulations  allow  a  party  to  request  an  SIME  within  60  days  of  receiving  a  medical  report  



that  raises  a  factual  dispute;  failure  to  comply  with  that  deadline  waives  a  party's  right  to  



                         40  

request  an  SIME.           



                   Patterson   did   not   request   an   SIME  based   on   the   difference  between   her  



physicians'  opinions  and  Dr.  Sheorn's  opinion  until  July  2019,  more  than  eight  months  



after  the  Board's  final  decision  on  her  claim  in  October  2018,  more  than  17  months  after  



the  January  2018  hearing  on  her  claim,  and  more  than  18  months  after  she  first  received  



Dr.  Sheorn's  report  in  December  2017.   She  has  never  explained  the  reason  for  the  long  



delay.   In  light  of  this  delay,  the  Board  did  not  abuse  its  discretion  when  it  denied  her  



petition  for  an  SIME.

         D.	      The  Board  Did  Not  Err  By  Sustaining  Objections T                     o  Parts Of Susan  

                  Magestro's  Testimony.41  



                  Patterson  argues  that  the  Board  erred  by  excluding  testimony  that  she  tried  



to  elicit  from   Susan  Magestro  about Patterson's  psychological  diagnoses.   Relying  on  



                                              42  

cases   about   scientific   evidence,            Patterson   contends  Magestro   had   the   necessary  



qualifications  to  contradict  Dr.  Sheorn's  diagnosis.   Patterson  cites  Magestro's  testimony  



-  possibly  made  as  an  offer  of  proof  at  a  different  hearing  -  that  in  her  professional  



opinion  Patterson  did  not  "present"  as  having  a  borderline  personality  disorder,  as  Dr.  



Sheorn  had  diagnosed.   The  District  maintains  the  Board  properly  exercised  its  discretion  



in  sustaining   the   District's   objections   to   Magestro's   testimony   about   Patterson's  



condition.  



                  Patterson's  legal  argument  is somewhat unclear, but we understand her to  



argue  that  the  Board's  reliance  on  Magestro's  admitted  lack  of  medical  or  psychological  



training  was  error  because  the  Board  ignored  the  expertise  she  had  acquired  through  her  



work   experience.     Experts   can   acquire   expertise   through   experience   as   well   as  



          41       We  review  the  Commission's  decision  in  a  workers'  compensation  appeal  



 rather  than the Board's,  Mitchell v. United Parcel Serv., 498  P.3d 1029, 1039 (Alaska  

 2021).   Here  the  Commission  summarized  Magestro's  training and  her  lack  of  certain  

 professional  qualifications,  but  it  did  not  discuss  Patterson's  argument  that  the  Board  

 should  have  allowed  Magestro  to  offer  an opinion about Patterson's  diagnoses.   In  her  

 brief  to us,  Patterson  contends  the Board  erred  in  refusing  to  allow  part  of  Magestro's  

 testimony.   The  applicable  standard  of  review  requires  us  to  independently  assess  the  

 Board's  actions,  id.,  so  we  address  directly  Patterson's  argument.   



          42       Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993); State v. Coon,

education.         But  it  is  not  clear  how  Magestro's  testimony  about  Patterson's  presentation  



was  relevant  to  the  issues  before  the  Board.   Patterson's  mental  health  diagnosis was a  



contested   issue,   and  Magestro   clearly   conceded   she  was  not   qualified  to  make   such   a  



diagnosis.   We  see  no  error  or  abuse  of  discretion in  the  Board's  decision  not  to  allow  



Magestro   to   express   the   expert   opinion   Patterson   sought   to   counter   Dr.   Sheorn's  



diagnosis.  



                   Moreover,  Patterson  does  not   show  how  exclusion  of  this  testimony  was  



prejudicial.     Patterson   presented   the   opinions   of   several   medical   experts   who   were  



qualified  to  make  psychological  diagnoses  and  who  agreed  she  had  PTSD,  yet  the  Board  



gave   more   weight   to   Dr.  Sheorn's  opinion   that   Patterson   did   not   have   PTSD.     We  



therefore  fail  to  see  how  excluding  Magestro's  testimony  was  prejudicial.   



         E.        Patterson's  Remaining  Arguments  Are  Waived  Or  Moot.  



                   Patterson's challenge to the Board's exclusion of her attorney's fees affidavit  



is   moot   because   we   affirm   the   Commission's   decision   on   the   merits   of   Patterson's  

compensation  claim.44

proceedings  are  awarded  only  when  she  prevails  on  the  claim;                   Patterson  did  not  prevail,

                  Patterson's  inadequate  briefing  to  us             waived  her  claims  that  (1)  the  Board

failed  to  provide  her  a  fair  opportunity  to  cross-examine  Dr.  Sheorn;                (2)  the  Board  failed  



to   consider  her   aggravation   claim; and   (3)   the   Board   failed   to   declare   a   "mistrial"   or  



reopen  the  record  to  allow  her  the  opportunity  to  present  additional  evidence.  



V.       CONCLUSION  



                  We  AFFIRM  the  Commission's  decision.  



          46        Patterson  made  these  arguments  to the Commission, but  the  Commission  



 did  not  address  them.   We  summarize  the  arguments  as  Patterson  framed  them  in  her  

 briefing  to  us.   



          47        Additionally, Patterson waived this argument by  acquiescing to the Board's  



 time  allotment  proposal  at  the  outset  of  the  hearing.   See  Williams  v.  Abood ,  53  P.3d  134,  

  148   (Alaska   2002)   ("[F]ailure   to   make   the   appropriate   objection   during   the   hearing  

 waives  the  right  to  appeal  procedural  errors.").
