Association of AM-PAC “6-Clicks” Basic Mobility and Daily Activity Scores With Discharge Destination
Abstract Objective Using AM-PAC “6-Clicks” scores at initial physical therapist and/or occupational therapist evaluation to assess: (1) predictive ability for community versus institution 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 (6CBM) and/or Daily Activity (6CDA) 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 10/1/15–8/31/18. 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 6CBM and 6CDA 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 6CBM (≤40.78 vs > 40.78) and 6CDA (≤40.22 vs > 40.22), accounting for patient and clinical characteristics. Results Area under the curve (AUC) for 6CBM was 0.80 (95% CI = 0.80–0.81) and 6CDA was 0.81 (95% CI = 0.80–0.82). The best cut-point for 6CBM was 40.78 (raw score = 16; sensitivity = 0.71 and specificity = 0.74) and for 6CDA was 40.22 (raw score = 19; sensitivity = 0.68 and specificity = 0.79). 6CBM and 6CDA were significantly associated with discharge destination, with those above the cut-point resulting in increased odds of discharge HOME. The 6CBM 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]) 6CDA 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]). Conclusions “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 6CBM and 6CDA scores are valuable clinical tools in the determination of discharge destination.
