Abstract
In order to provide quality and cost-effective health care, hospitals have used a variety of organizational models. Chain hospitals are one type of organization and service delivery model. Based on the diversity, multiplicity, and ambiguous nature of concepts related to chain hospitals, this study is an attempt to explain the concepts and components of such hospitals. Five main databases were searched for this purpose. Scopus, PubMed, WOS, ProQuest, and Wiley library databases were accessed from inception to September 2022. English-language studies describing chain hospital models were included. Two independent authors screened full-text papers, and data were extracted using a self-designed form. A thematic analysis was used to identify key components of the chain hospitals. A total of 38 papers from 8472 documents met the inclusion criteria and were included in the study. Among the selected studies, there were 23 quantitative studies, 6 qualitative studies, 5 mixed studies, 3 review studies, and 1 gray report. A review of the results revealed 55 different definitions of chain hospitals, as well as 6 main components and 16 subcomponents. Among the extracted components, 60% were related to the organization dimension, 15% to governance, 9% to decision rights, 8% to policies and procedures, and 4% to service delivery. In order to launch a multihospital system involving chain hospitals in a country, it is necessary first to define the concept of this hospital. The study's findings should be used by policymakers and officials in each country before implementing an inter-hospital cooperation system (MHS, chain hospital, etc.). Future researchers may also find inspiration in the study's findings and focus on these hospitals' establishment, effectiveness, and financial effects.
