- Abstract
- PURPOSE: Evaluate the clinimetric properties and clinical utility of the Short Physical Performance Battery (SPPB) in survivors of critical illness up to 6 months post-hospital discharge. MATERIALS AND METHODS: Clinimetric analysis of three international datasets (n = 488 ICU survivors) from the United States and Australia. RESULTS: At hospital discharge, the SPPB demonstrated moderate-to-excellent construct validity with the six-minute walk test (rho = 0.81, p < 0.001), Timed Up and Go (TUG) (rho = -0.87, p < 0.001), and dual TUG (rho = -0.75, p < 0.001); and fair-to-moderate construct validity with handgrip and quadriceps strength. At hospital discharge it predicted minimal to mild limitations (score 7-12) at 6 months post (AUC 0.78 [0.72-0.84]). Responsiveness was observed, with the largest effect size (0.72) between hospital discharge and 3 months. Minimal clinical difference (from distribution-based methods) ranged from 1.21 to 1.43 out of 12 across timepoints. Floor effects were present at hospital discharge (18.8%) and ceiling effects at 3- and 6-months post (26.5% and 28.1%). At 3 months post, participants with moderate-to-severe limitations (score 0-6) performed worse on physical and strength-based measures. CONCLUSIONS: The SPPB is a valid tool that can be used to monitor physical function recovery. It may have the potential for prediction of physical limitations particularly at hospital discharge, however further validation is required.; The Short Physical Performance Battery (SPPB) is a valid, responsive tool which may help direct rehabilitation supports at hospital discharge for intensive care unit (ICU) survivors.The SPPB may be a complementary measure alongside other established outcome measures to identify physical limitations and facilitate appropriate resource allocations to those may benefit more from physical rehabilitation.Clinicians can consider incorporating the SPPB into routine assessment to monitor recovery and guide rehabilitation planning in ICU survivors, particularly at hospital discharge and into the community.; eng
