Design: An observationalstudy.
Setting: A singlehospital.
Participants: Seventy-sixadultJehovah’s Witnessesrefus-
ingbloodtransfusionwhounderwentcardiacsurgeries.
Interventions: Patientsweredividedinto2groups
accordingtotheirTRACKscore:low-riskgroup(n ¼ 57,
TRACK scoreoflessthan13)andhigh-riskgroup(n ¼ 19,
TRACKscoreof13ormore).Perioperativeandlong-
term clinicaloutcomeswerecomparedbetweenthe2
groups.
MeasurementsandMainResults: The operativemortality
was 0%inthelow-riskgroup,and21.1%(n ¼ 4) inthehigh-
risk group(p ¼ 0.003). Theincidenceofmajorpostoperative
complicationswashigherinthehigh-riskgroup(57.9%)thanin
the low-riskgroup(17.5%)(p ¼ 0.002).Thehigh-riskgrouphad
more postoperativebleeding-relatedcomplications(21.1%)
than didthelow-riskgroup(1.8%)(p ¼ 0.013). Therewere
no significant differencesofpredictive performanceinmortal-
ity andmorbiditybetweentheTRACKscoreandEuroSCOREII.
Conclusion: In cardiacsurgerypatientsrefusingtransfu-
sions, theTRACKscorepredictedpostoperativemorbidity
and mortalityofcardiacsurgery.
