To update a previous review on whether additional physical therapy services reduce length of stay, improve health outcomes, and are safe and cost-effective for patients with acute or subacute conditions.
Electronic database (AMED, CINAHL, EMBASE, MEDLINE, Physiotherapy Evidence Database [PEDro], PubMed) searches were updated from 2010 through June 2017.
Randomized controlled trials evaluating additional physical therapy services on patient health outcomes, length of stay, or cost-effectiveness were eligible. Searching identified 1524 potentially relevant articles, of which 11 new articles from 8 new randomized controlled trials with 1563 participants were selected. In total, 24 randomized controlled trials with 3262 participants are included in this review.
Data were extracted using the form used in the original systematic review. Methodological quality was assessed using the PEDro scale, and the Grading of Recommendation Assessment, Development, and Evaluation approach was applied to each meta-analysis.
Postintervention data were pooled with an inverse variance, random-effects model to calculate standardized mean differences (SMDs) and 95% confidence intervals (CIs). There is moderate-quality evidence that additional physical therapy services reduced length of stay by 3 days in subacute settings (mean difference [MD]=–2.8; 95% CI, –4.6 to –0.9; I2=0%), and low-quality evidence that it reduced length of stay by 0.6 days in acute settings (MD=–0.6; 95% CI, –1.1 to 0.0; I2=65%). Additional physical therapy led to small improvements in self-care (SMD=.11; 95% CI, .03–.19; I2=0%), activities of daily living (SMD=.13; 95% CI, .02–.25; I2=15%), and health-related quality of life (SMD=.12; 95% CI, .03–.21; I2=0%), with no increases in adverse events. There was no significant change in walking ability. One trial reported that additional physical therapy was likely to be cost-effective in subacute rehabilitation.
Additional physical therapy services improve patient activity and participation outcomes while reducing hospital length of stay for adults. These benefits are likely safe, and there is preliminary evidence to suggest they may be cost-effective.
