The purpose of this study is to clarify the characteristics of awareness and behavior for falling accident prevention according to medical profession. We used a questionnaire called "Self-Evaluation of Awareness and Behavior for Falling Accident Prevention," which was originally designed for nurses. In October and November 2016, the questionnaire was administered to 1,670 medical staff (nurses, doctors, lab technicians, nursing assistants, radiological technicians, pharmacists, physical therapists, nutritionists, and occupational therapists, among others) at a hospital in Japan, using a 5-step scale and a not applicable (N/A) option. Valid responses were obtained from 923 (55.3%) participants, and all seven factors extracted by factor analysis had Cronbach's α coefficients of greater than 0.9. Using cluster analysis based on principal component analysis, four categories were identified. According to the results of the N/A χ2 (chi-square) test question item and occupation, nurses answered N/A the least, followed by doctors, physical therapists, and occupational therapists. Nursing assistants' awareness and behavior were both low, suggesting the necessity of education on preventing falling accidents. By applying the "Self-Evaluation of Awareness and Behavior for Falling Accident Prevention" to all medical staff, we succeeded in clarifying their characteristics of awareness and behavior for falling accident prevention.
