Abstract
This systematic review examined peer-reviewed literature published from 2010 to 2020 to investigate the health care system costs, hidden out-of-pocket expenses and quality of life impact of surgical site infections (SSIs) and to develop an overall summary of the burden they place on patients. SSI can significantly impact patients' treatment experience and quality of life. Understanding patients' SSI-related burden may assist in developing more effective strategies aimed at lessening the effects of SSI in financial and well-being consequences. Peer-reviewed articles on adult populations (over 18 years old) in orthopaedic elective hip and knee surgeries published from 2010 to 2020 were considered. Only publications in English and studies conducted in high-income countries were eligible for inclusion. A search strategy based on the MESH term and the CINAHL terms classification was developed. Five databases (Scopus, EMBASE, CINAHL, Medline, Web of Science) were searched for relevant sources. Reviewers categorised and uploaded identified citations to Covidence and EndNoteX9. Reviewers will assess article titles, abstracts and the full text for compliance with the inclusion criteria. Ongoing discussions between reviewers resolved disagreements at each selection process stage. The final scoping review reported the citation inclusion process and presented search results in a PRISMA flow diagram. Four main themes were extracted from a thematic analysis of included studies (N = 30): Hospital costing (n = 21); Societal perspective of health system costing (n = 2); Patients and societal well-being (n = 6) and Epidemiological database and surveillance (n = 22). This systematic review has synthesised a range of themes associated with the overall incidence and impact of SSI that can inform decision making for policymakers. Further analysis is required to understand the burden on SSI patients.
