Appropriate use of inpatient physical therapy services is important for preventing hospital-associated disability (HAD). We assessed potential overutilization of physical therapy consults on hospital medicine services using the Activity Measure-Post Acute Care (AM-PAC) score. Our sample included 3592 unique admissions (mean age, 66 years; 48% women) at a large academic medical center. Based on an AM-PAC cutoff of >43.63 (raw score, 18) in patients who were discharged to home, 38% of physical therapy consults were considered “potential overutilization.” Combined with age <65 years, 18% of consults remained “potential overutilization.” After adjustment for age, sex, and length of stay, patients admitted with high mobility scores were 5.38 times more likely to be discharged to home (95% CI, 4.36-2.89) compared with those with low mobility scores. Being more judicious with physical therapy consults and reserving skilled therapy for at-risk patients could help prevent HAD while also having a positive impact on healthcare systems.
OBJECTIVES/GOALS: Physical therapy (PT) is key for treating functional decline that inpatients experience but is a constrained resource in hospital settings. The Activity Measure Post-Acute Care (AM-PAC) score is a mobility measurement tool that has been used to define misallocation of PT. We aim to optimize PT referrals using AM-PAC-based clinical decision support . METHODS/STUDY POPULATION: We conducted a prospective study of patients admitted to University of Chicago Medical Center. AM-PAC scores were assessed by nursing staff every 12 hours. Clinical decision support was designed using validated AM-PAC cutoffs (> 18, a predictor of discharge to home). The tool was embedded in hospital medicine note templates, requiring providers to indicate PT referral status based on current AM-PAC scores. The primary outcome, unskilled consult , was defined as PT referral for patients with AM-PAC > 18. Data were collected for one year prior to implementation and one year after implementation for intervention (hospital medicine) and control (general internal medicine) services. Difference in differences analysis was used to assess the association between the intervention and unskilled consults. RESULTS/ANTICIPATED RESULTS: Between October 2018 and March 2021, 18,241 admissions were eligible for the study. Compared to preintervention, there was a lower rate of referral to PT for patients with high AM-PAC mobility scores in the post-intervention period [18.5% vs 16.6%; X2(1) = 7.02; p < 0.01]. In the postintervention time period, the control group experienced a 2.6% increase in unskilled consults while the intervention group experienced a 2.3% decrease, a difference in differences of 4.9% (95% CI -0.07–-0.03 for difference in differences) controlling for age sex, race, LOS, and change in mobility. Compared to preintervention, there was no statistically significant difference in mean change in mobility score post-intervention for either group. DISCUSSION/SIGNIFICANCE: Our results suggest that clinical decision support can decrease unskilled PT consults. Many functionally independent patients can mobilize with nursing or other mobilization staff. Hospitals should consider mobility score-based decision support to prioritize PT for impaired and at-risk patients.
