Nursing Support for Constipation in Patients with Cancer: A Scoping Review

Constipation is an uncomfortable symptom experienced by many patients with advanced cancer, and it decreases the quality of life. Several studies have advised pharmacological therapies for constipation management, whereas others have promoted nonpharmacological approaches that promote changes in the patient's lifestyle. However, constipation management by nurses has not yet been systematically reviewed in patients with cancer. Therefore, this study conducted a scoping review of nursing support focused on nonpharmacological therapies offered to relieve constipation in patients with cancer. The review was guided by Arksey and O'Malley's five-stage scoping review framework. We searched the databases of PubMed, Cumulative Index to Nursing and Allied Health Literature, CENTRAL in the Cochrane Library, and Ichushi-Web of the Japan Medical Abstract Society from the databases' inceptions to August 31, 2023, using various search terms such as "cancer," "constipation," and "nursing care." A total of 1501 articles that met the eligibility criteria were identified; of these, 5 articles were selected, and 1 additional article was found via handsearching. The final sample included six articles. We categorized the articles into three major nursing support types: acupressure, aroma massage to the abdomen, and self-management education. Five studies used a randomized controlled trial (RCT) design, including one with a randomized, waiting-list controlled trial, and one used a non-RCT design. All included studies showed the effectiveness of nonpharmacological interventions to improve constipation. This study also identified three types of nursing support for patients with cancer to relieve constipation. However, because of the small sample size, further evidence is required.
