Systematic literature review of the methodology for developing pharmacotherapeutic interchange guidelines and their implementation in hospitals and ambulatory care settings.

purposeTo summarize literature specific to therapeutic interchange (TI) focusing on methodological approaches in order to develop a list of steps that healthcare facilities can consult when developing pharmacotherapeutic interchange guidelines (PTIGs) in hospitals and primary care centers.

methodsA search was conducted in PreMEDLINE, Medline, EMBASE, PsycINFO, and the Cochrane Library up to and including December 2015. PRISMA guidelines were used. The inclusion criteria were articles published on TI: methodology, implementation, guidelines, and position statements of scientific societies. Two authors independently reviewed all articles for eligibility and extracted the data.

resultsA total of 102 articles were selected for full-text review; we included three guidelines on how to effect TI, nine position papers of various scientific societies with regard to TI, two articles dealt exclusively about methodology, three articles consisted of recommendations and perspectives on TI, three articles dealt with legal aspects, four articles examined general implementation procedures, two articles were a post-discharge follow-up of patients who had TI, six were surveys referring to TI, and three were articles on the use of TI in ambulatory care The remaining 67 articles focused on therapeutic groups. Study quality was generally low.

conclusionsThis review identified articles on TI as published guidelines, recommendations, and studies on TI carried out in hospital settings. As a result, eight fundamental steps were established for obtaining adequate results in the development of TI programs.
