Since physical rehabilitation is a primary therapy for patients in a cerebrovascular disease recovery unit, it is important to prevent accidental falls due to impaired physical functioning in such patients. In the present study, we retrospectively investigated the risk factors of in-hospital accidental falls, taking administered drugs and activities of daily living into account. To do this, we did a search of the electronic medical records of all patients who had been admitted to our hospital from May to October 2005. Falls due to seizures or apparently caused by careless mistakes made by medical staff were excluded from the accidental fall count. Patients' age, sex, primary disease, date of fall, and prescriptions (e.g. antihypertensives, antipsychotics, anticonvulsants) were taken from the records for statistical screening for fall risk factors, which was performed by multiple logistic regression analysis. There had been a total of 144 accidental falls in 447 patients. There were no statistically significant differences in patients' demographics between the falls group (n=144) and no falls group (n=303). Multiple logistic regression analysis showed that administration of minor tranquilizers and the Barthel index at hospital admission were statistically significant risks for accidental falls with odds ratios of 2.2 [95% confidence interval: 1.1 to 4.4; p<0.01] and 4.9 [2.4 to 10.1; p<0.05], respectively. We concluded that patients taking minor tranquilizers should be monitored more carefully to avoid accidental falls, and such careful monitoring would be particularly important for patients with a low Barthel index following a cerebrovascular disease.
