Public health nurses (PHNs) face difficulties supporting vulnerable individuals and families. On-the-job training (OJT) is essential for improving nurses' competencies. However, PHN managers lack the knowledge to systematically implement OJT. The aim of this study was to develop a hypothetical model to systematically promote OJT for PHNs through case conferences (CC). Literature review, based on an integrative approach, has three stages: (1) theoretical framework development, (2) literature review, and (3) modeling. Literature review from five databases (MEDLINE, CINAHL, PsycInfo, Cochrane Central Register of Controlled Trials, Japan Medical Abstract Society) was conducted to identify the OJT process, its outcomes, and the conditions associated with OJT according to the theoretical framework. Based on 18 articles, this model progressed from "OJT process through CC," comprising the CC design, implementation, and evaluation to OJT produced "outcomes through CC." Outcomes included staff perception and behavior changes, improvements in client's condition, and staff turnover reductions. The OJT model involved "conditions for implementing CC as OJT" and "individual and organizational conditions." Future research should incorporate the social, political, and historical contexts of specific practice situations into the hypothetical model to help refine the model to be used in practice.
