ABSTRACT
AIM: To clarify the performance situation of selected quality indicators: falls, pressure ulcers and dehydration, at health care facilities for the elderly in Japan, and what structural characteristics are related to them. METHODS: The operational population consisted of 1057 institutionalized users (approximately 10 randomly selected per facility) from a survey answered by the care staff. The facilities were divided into two groups according to their prevalence of negative outcomes (falls, pressure ulcers, dehydration): the best 25% (the very good performers) and the remaining 75% (not so good performers). Logistic regression analysis was carried out to examine the relationship between the structure characteristics of the facilities and their performance regarding each quality indicator. RESULTS: After controlling for sex, years of operation and average age of the users, our results showed a beneficial significant relationship between falls and the total number of nurses per 100 users with an adjusted odds ratio (AOR) of 0.77 (95% CI 0.59-0.98); In contrast, for pressure ulcers, harmful associations between a higher number of registered nurses (AOR 1.23, 95% CI 1.01-1.05) and the availability of 24-h nurse staffing (AOR 4.95, 95% CI 1.19-24.91) were found; regarding dehydration, we did not find any related staffing characteristics. CONCLUSION: Nursing staff might be considered as a potentially related variable in the quality of care in health care facilities for the elderly. The present study is the first to show a relationship between structural characteristics and quality outcomes in health care facilities for the elderly.
