AIM: This study examined the home care nurses' implementation of comprehensive assessment of their clients, their education and the association betwwen the two. Staff education in home care nursing agencies has the potential to improve nurses' comprehensive client assessment, contributing to the provision of high-quality home care nursing services. METHODS: A cross-sectional questionnaire survey was conducted to investigate educational approaches provided by agencies and comprehensive assessment by home care nurses. Multilevel regression analyses were performed to examine the association between education and comprehensive assessment. RESULTS: We analyzed data from 105 clients, based on 78 nurses' assessments, across 11 agencies with respect to their respective staff education systems. Various educational programs for novices and all staff were provided. In the multilevel regression analysis, having a designated individual in charge of staff education and regular case reviews for all staff were significantly associated with more comprehensive assessments. CONCLUSIONS: Ensuring specific educational opportunities for all home care nurses, rather than solely for novices, might improve their comprehensive assessment in home care nursing agencies. Designating educators and introducing regular case reviews as part of agencies' educational systems may improve comprehensive assessment. Geriatr Gerontol Int 2025
