The aim of this brief report is to present the protocol and preliminary findings of a systematic review on key aspects of care provision that affect care transition of older adults 60+ within the long-term care systems. This brief report describes and classifies the relevant literature found in the review with the purpose to provide a base for further full systematic reviews, and to outlines a model of organizational and financing aspects that affect care transition. Our search was conducted in MEDLINE, Embase and CINAHL on 2 March 2020, before the COVID-19 pandemic. The protocol was registered at the International Prospective Register of Systematic Reviews (number: CRD42020162566). Ultimately, 229 full-text records were found eligible for further deliberation. We observed an increase in the number of publications on organizational and financial aspects of care transition since 2005. Majority of publications came from the United States, United Kingdom and Australia. In total, 213 (92%) publications discussed organizational aspects and only 16 (8%) publications were related to financial aspects. Records on organizational aspects were grouped into the following themes: communication among involved professional groups, coordination of resources, transfer of information and care responsibility of the patient, training and education of staff, e-health, education and involvement of the patient and family, social care, and opinion of patients. Publications on financial aspects were grouped into provider payment mechanisms, incentives and penalties. Overall, our search pointed out various care provision aspects being studied in the literature, which can be explored in detail in subsequent full systematic reviews focused on given aspects. We also present a model based on our preliminary findings, which enables us to better understand what kind of provision aspects affect care transition. This model can be tested and validated in subsequent research. Understating factors that affect care transition is crucial to improve the quality of transitions and ultimately the outcomes for the patients.
