Characteristics of falls in orthopedic patients during hospitalization.

Falls are common in elderly patients and comprise 20-30% of all incident reports in hospitals. The current study examined falls in orthopedic patients among 212,617 inpatients admitted to our hospital from April 2012 to March 2017, using a prospective database in the hospital event reporting system. The risk of fall was evaluated using a fall assessment scoresheet at admission and during hospitalization, based on which patients were divided into risk grades 1, 2 and 3. Fall leading to fracture or a life-threatening injury was defined as an adverse event. The number of falls during the study period was 3,925, including 230 in orthopedic patients. Fall cases occurred at all times, but adverse events were significantly more common from 1-7 a.m. (67% vs. 24%, p<0.01). Patients hospitalized for orthopedic surgery had significantly higher fall rates compared to all other patients (3.12% vs. 1.80%, p<0.01), and were older (65.8 vs. 61.4 years, p<0.05) and more frequently >80 years old (23.4% vs. 17.9%, p<0.05). There was a significant difference in fall incidence between risk grades 2 and 3 for patients hospitalized for non-orthopedic surgery, but not for patients hospitalized for orthopedic surgery. We conclude that fall can occur in orthopedic patients with a low predicted risk of fall, and particularly for older patients. This may indicate that frequent specialized fall assessment is desirable after orthopedic surgery.
