PSMATCH code for optimal paired matching after multiple imputation

[UcheOkoro]

Hello,

Please I need help with PSMATCH code for optimal paired matching after multiple imputation. I do not know how to make it match each imputed data. I am familar with using PSMATCh for  a single data set not multiple.

The following is my code below.

Thank you.

proc psmatch data=mi_fcs2 region=cs;
class telemed_use sex  mode_arrival pmh_copd pmh_cirrhosis pmh_transplant pmh_cancer pmh_diabetes pmh_dialysis  ;
psmodel telemed_use(Treated='1')= sex Age2 bmi2 triage_pulse2 infection_ed_source2 total_sofa1_ed2 mode_arrival pmh_copd pmh_cirrhosis pmh_transplant 
                                     pmh_cancer pmh_diabetes pmh_dialysis triage_systolic  Lactate1_cat firsted_hosp2 ;

output out(obs=match)=Outgs ps=_ps matchid=_MatchID;
run;
