Non-pharmacological interventions for chemotherapy-induced diarrhoea and constipation management: A scoping review.

ABSTRACT

PURPOSE: Chemotherapy-induced diarrhoea (CID) and constipation (CIC) are among the most common and severe gastrointestinal symptoms related to chemotherapy. This review aimed to identify and describe the evidence for non-pharmacological interventions for the management of CID and CIC. METHODS: The scoping review was based on the Joanna Briggs Institute methodology and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Evidence from five databases were included CINAHL, MEDLINE, Embase, PubMed, and APA PsycInfo. Data were systematically identified, screened, extracted and synthesised narratively to describe the evidence for non-pharmacological interventions and their effects on CID and CIC. RESULTS: We included 33 studies, of which 18 investigated non-pharmacological interventions for CID management, six for CIC management, and nine for both CID and CIC management. Interventions were categorized into five groups, including (1) digital health interventions, (2) physical therapies, (3) diet and nutrition therapies, (4) education, and (5) multimodal. Diet and nutrition therapies were the most common to report potential effectiveness for CID and CIC outcomes. Most of the interventions were implemented in hospitals under the supervision of healthcare professionals and were investigated in randomised control trials. CONCLUSIONS: The characteristics of non-pharmacological interventions were diverse, and the outcomes were inconsistent among the same type of interventions. Diet and nutritional interventions show promise but further research is needed to better understand their role and to contribute to the evidence base. Nurses are well placed to assess and monitor for CIC and CID, and also deliver effective non-pharmacological interventions.
