Infection prevention and control practice among home‐care nursing agencies in Japan: Secondary analysis of a nationwide cross‐sectional survey

AIM: We describe the nationwide situation of infection prevention and control (IPC) practices among home‐visit nursing agencies and compare them by agency size to explore whether these practices are associated with the occurrence of infection. METHODS: We conducted a secondary analysis using data from a cross‐sectional nationwide survey inspecting patient safety and IPC practices among nationwide home‐visit nursing agencies, from March to April 2020. Among 9978 agencies, 580 responded and 370 were incorporated in the analysis. The self‐administered questionnaire inquired about the IPC policy and administrative structure, education and training, adherence to standard precautions, and employee health programs. We described the adherence to IPC practice at the agency level and compared them by agency size using chi‐squared tests. Logistic regression analysis was performed to explore the associations between IPC practices and incidence of infection. RESULTS: Adherence to IPC practices ranged from 19.2% to 92.4% and varied according to agency size. Less than 20% of agencies had instituted a committee for IPC and strictly used disposable aprons when changing patients' diapers. Instituting a committee for IPC (odds ratio 2.19, 95% confidence interval 1.11–4.34, P < 0.05) and training staff for infection prevention (odds ratio 1.67, 95% confidence interval 1.02–2.72, P < 0.01) were significantly associated with the incidence of infection, after adjusting for covariates. CONCLUSIONS: There are challenges in establishing IPC policies and administrative structures and adhering to standard precautions. Well‐organized agencies were found to be more likely to detect infections occurring over the past 3 months. Geriatr Gerontol Int 2021; 21: 913–918.
