Key result
Higher pre-operative SPPB scores predict ~23% lower hospital mortality and major morbidity per point.
Why the study?
The STS score has limited predictive value in older persons, prompting evaluation of whether the Short Physical Performance Battery improves assessment of in-hospital prognosis beyond the STS score.
Does the Short Physical Performance Battery (SPPB) improve prediction of hospital mortality and major morbidity in older patients undergoing elective cardiac surgery compared to the STS score alone?
Population
235 patients aged 75+ years undergoing elective cardiac surgery
Comparison
Short Physical Performance Battery (SPPB) added to STS score vs STS score alone

The Short Physical Performance Battery (SPPB) improves pre-operative risk stratification for mortality and major morbidity in older patients undergoing elective cardiac surgery who are classified as low risk by the STS score.
Baldasseroni et al. (2020) conducted a cohort in Elective cardiac surgery (n=235). Short Physical Performance Battery (SPPB) was evaluated on Hospital mortality and STS-defined major morbidity (OR 0.77, 95% CI 0.66-0.89, p=<0.001). Higher pre-operative Short Physical Performance Battery scores predicted lower hospital mortality and major morbidity in low-risk older patients (OR 0.77 per point increase; 95% CI 0.66-0.89; p<0.001).
