Clinical Characteristics and Outcomes of Inpatient Falls During Inpatient Rehabilitation: A Case-Control Study

Inpatient falls have a significant impact on the outcomes of older patients during inpatient rehabilitation. A retrospective case-control study was conducted using data of 7066 adults aged 55 yrs or older to evaluate significant predictors of inpatient falls during inpatient rehabilitation and the association of inpatient falls with discharge destination and length of stay. A stepwise logistic regression was used to model odds of inpatient falls and home discharge with demographic and clinical characteristic variables and a multivariate linear regression to evaluate the association between inpatient falls and length of stay.Nine hundred thirty-one of 7066 patients (13.18%) had inpatient falls during inpatient rehabilitation. The group with inpatient falls had longer length of stay (14.22 ± 7.82 vs. 11.85 ± 5.33 days, P < 0.0001) and a decreased proportion of home discharges when compared with the group without inpatient falls. There were increased odds of inpatient falls among patients with diagnoses of head injury, other injuries, a history of falls, dementia, a divorced marital status, and a use of laxatives or anticonvulsants. Inpatient falls were associated with an increased length of stay (coefficient = 1.62, confidence interval = 1.19-2.06) and decreased odds of home discharge (odds ratio = 0.79, confidence interval = 0.65-0.96) after inpatient rehabilitation. This knowledge may be incorporated into strategies for reducing inpatient falls during inpatient rehabilitation.
