Association between physical therapy frequency and postacute care for a national cohort of patients hospitalized with pneumonia.

We included 18,886 patients from 595 hospitals. Just over half were discharged home (n = 9638; 51.0%) and 558 (2.95%) died. Patients getting more frequent therapy were older, non-Hispanic white, treated in small non-teaching rural hospitals in the West, Midwest, or South, and had fewer severe illness indicators. In adjusted models, patients who received physical therapy on 100% of days were 7% [(95% confidence interval, 4.3-9.7), p < .0001] more likely to go home than patients who received physical therapy on 40% of days. As a falsification test, we found that there was no relationship between physical therapy frequency and all-cause mortality. Physical therapy visit frequency was positively associated with discharge to home. Increasing visit frequency of physical therapy in hospitals might reduce the need for postacute care, but randomized controlled trials are needed to confirm the effect.
