Abstract
Objectives
To evaluate the negative effect of physical restraint use on the hospital outcomes of older patients.
Design
A retrospective cohort study.
Setting
Internal medicine wards of a tertiary medical center in Taiwan.
Participants
Subjects aged 65 years and over who were admitted during April to Dec 2017 were recruited for study.
Measurements
Demographic data, geriatric assessments (polypharmacy, visual impairment, hearing impairment, activities of daily living before and after admission, risk of pressure sores, change in consciousness level, mood condition, history of falls in the previous year, risk of malnutrition and pain) and hospital conditions (admission route, department of admission, length of hospital stay and mortality) were collected for analysis.
Results
Overall, 4,352 participants (mean age 78.7±8.7 years, 60.2% = male) were enrolled and 8.3% had physical restraint. Results of multivariate logistic regression showed that subjects with physical restraints were at greater risk of functional decline (adjusted odds ratio 2.136, 95% confidence interval 1.322–3.451, p=0.002), longer hospital stays (adjusted odds ratio 5.360, 95% confidence interval 3.627–7.923, p<0.001) and mortality (adjusted odds ratio 4.472, 95% confidence interval 2.794–7.160, p<0.001) after adjustment for covariates.
Conclusion
The use of physical restraints during hospitalization increased the risk of adverse hospital outcomes, such as functional decline, longer length of hospital stay and mortality.
