Association of AM-PAC “6-Clicks” Basic Mobility and Daily Activity Scores With Discharge Destination

Abstract

Abstract Objective The objective was to use the Activity Measure for Post-Acute Care “6-Clicks” scores at initial physical therapist and/or occupational therapist evaluation to assess (1) predictive ability for community versus institutional discharge, and (2) association with discharge destination (home/self-care [HOME], home health [HHA], skilled nursing facility [SNF], and inpatient rehabilitation facility [IRF]). Methods In this retrospective cohort study, initial “6-Clicks” Basic Mobility and/or Daily Activity t scores and discharge destination were obtained from electronic health records of 17,546 inpatient admissions receiving physical therapy/occupational therapy at an academic hospital between October 1, 2015 and August 31, 2018. For objective (1), postacute discharge destination was dichotomized to community (HOME and HHA) and institution (SNF and IRF). Receiver operator characteristic curves determined the most predictive Basic Mobility and Daily Activity scores for discharge destination. For objective (2), adjusted odds ratios (OR) from multinomial logistic regression assessed association between discharge destination (HOME, HHA, SNF, IRF) and cut-point scores for Basic Mobility (≤40.78 vs >40.78) and Daily Activity (≤40.22 vs >40.22), accounting for patient and clinical characteristics. Results Area under the curve for Basic Mobility was 0.80 (95% CI = 0.80–0.81) and Daily Activity was 0.81 (95% CI = 0.80–0.82). The best cut-point for Basic Mobility was 40.78 (raw score = 16; sensitivity = 0.71 and specificity = 0.74) and for Daily Activity was 40.22 (raw score = 19; sensitivity = 0.68 and specificity = 0.79). Basic Mobility and Daily Activity were significantly associated with discharge destination, with those above the cut-point resulting in increased odds of discharge HOME. The Basic Mobility scores ≤40.78 had higher odds of discharge to HHA (OR = 1.7 [95% CI = 1.5–1.9]), SNF (OR = 7.8 [95% CI = 6.8–8.9]), and IRF (OR = 7.5 [95% CI = 6.3–9.1]), and the Daily Activity scores ≤40.22 had higher odds of discharge to HHA (OR = 1.8 [95% CI = 1.7–2.0]), SNF (OR = 8.9 [95% CI = 7.9–10.0]), and IRF (OR = 11.4 [95% CI = 9.7–13.5]). Conclusion 6-Clicks at physical therapist/occupational therapist initial evaluation demonstrated good prediction for discharge decisions. Higher scores were associated with discharge to HOME; lower scores reflected discharge to settings with increased support levels. Impact Initial Basic Mobility and Daily Activity scores are valuable clinical tools in the determination of discharge destination.
