Impact of Preoperative Patient Education on Postoperative Recovery in Abdominal Surgery: A Systematic Review

Abstract

Background: Patient education is recommended as an essential component of Enhanced Recovery after Surgery (ERAS) protocols. However, there are many uncertainties regarding content and methodological criteria, which may have a significant impact on the effectiveness of the intervention. The aim of this review is to assess the effect of preoperative patient education on postoperative recovery in abdominal surgery and to examine different patient education strategies for their effectiveness. Methods: We performed a systematic review according to the PRISMA guidelines. PubMed, CINAHL, and Cochrane were searched from 2011 to 2022. All studies investigating the effect of preoperative patient education on postoperative recovery in abdominal surgery were included. A critical quality assessment of all included studies was performed. Results: We identified 826 potentially suitable articles via a database search and included 12 studies in this review. The majority of the included studies reported a reduction in the length of hospital stay (LOS) and even a reduction in postoperative complications and adverse events. Patients with preoperative education seemed to have lower psychological stress and experience less anxiety. However, the contents, delivery, and general conditions were implemented differently, making comparison difficult. Moreover, the majority of the included studies were weak in quality. Conclusion: With this review, we report potential effects, current implementations, and frameworks of patient education. However, the results must be interpreted with caution and are not directly transferable to clinical practice. Further studies in this field are necessary to make concrete recommendations for clinical practice.
