Abstract

Objective: To determine the change in rates of physical restraint (PR) use and associated outcomes among hospitalized adults.

Patients and methods: Using national inpatient sample databases, we analyzed years 2011-2014 and 2016-2019 to determine trends of PR usage. We also compared the years 2011-2012 and 2018-2019 to investigate rates of PR use, in-hospital mortality, length of stay, and total hospital charges.

Results: There were 242,994,110 hospitalizations during the study period. 1,538,791 (0.63%) had coding to signify PRs, compared with 241,455,319 (99.3%), which did not. From 2011 to 2014, there was a significant increase in PR use (p-trend<.01) and a nonsignificant increase in PR rates from 2016-2019 (p-trend=.07). Over time, PR use increased (2011-2012: 0.52% vs 2018-2019: 0.73%; p<.01). Patients with PRs reported a higher adjusted odds for in-hospital mortality in 2011-2012 (adjusted odds ratio [aOR], 3.9; 95% CI, 3.7-4.2; p<.01) and 2018-2019 (aOR, 3.5; 95% CI, 3.4-3.7; p<.01). Length of stay was prolonged for patients with PRs in 2011-2012 (adjusted mean difference [aMD], 4.3 days; 95% CI, 4.1-4.5; p<.01) and even longer in 2018-2019 (aMD, 5.8 days; 95% CI, 5.6-6.0; p<.01). Total hospital charges were higher for patients with PRs in 2011-2012 (aMD, +$55,003; 95% CI, $49,309-$60,679; p<.01). Following adjustment for inflation, total charges remained higher for patients with PRs compared with those without PRs in 2018-2019 (aMD, +$70,018; 95% CI, $65,355-$74,680; p<.01).

Conclusion: Overall, PR rates did not decrease across the study period, suggesting that messaging and promulgating best practice guidelines have yet to translate into a substantive change in practice patterns.
