Presenting a Comprehensive Definition of Unnecessary Healthcare Services and Their Drivers: A Systematic Review and Meta-synthesis.

Background: Providing unnecessary healthcare services is a major common problem in every health system. The scope and cause of healthcare services must be identified in order to be managed and controlled. Finding the most complete definition of the problem and its causes are the goals of this meta-synthesis.

Methods: A comprehensive search strategy was performed using a wide range of keywords and databases. Based on the defined inclusion and exclusion criteria, 22 articles were selected for content analysis and meta-synthesis. The Graneheim and Lundman method was used for content analysis. The MAXQDA software Version 18.2.0 was used for the first round of content analysis. Content analysis and meta-synthesis were used to comprehensively define the term "unnecessary healthcare services" and find the etiologic factors driving healthcare providers to unnecessary healthcare services.

Results: The term "unnecessary healthcare services" is defined as "overproviding healthcare services that could be harmful, low-value, insufficient, and inappropriate." The etiologic pattern of unnecessary healthcare services shows intrinsic and extrinsic factors as a driving force for unnecessary healthcare services.

Conclusion: A multilayer strategy for efficient management and prevention of unnecessary healthcare services is appropriate due to the multifaceted character of these services. This approach consists of the modification of the intrinsic factors and extrinsic drivers.
