Factors influencing inpatient bowel preparation: a scoping review

Abstract

AbstractBackground and AimInpatients undergoing colonoscopy experience a higher‐than‐average rate of inadequate bowel preparation (compared to outpatients) leading to canceled procedures, increased stress on the patient, increased time in hospital, and increased cost to the healthcare system. The aim of this scoping review was to identify research surrounding inpatient bowel preparation and to identify modifiable and non‐modifiable factors that influence the adequacy of bowel preparation in hospitalized patients undergoing colonoscopy and establish areas where nursing interventions may help improve overall bowel preparation rates.MethodsAn initial search of MEDLINE, CINAHL, Scopus, and Embase was undertaken to identify seed articles, followed by a structured search using keywords and subject headings. Studies conducted between 2000 and 2022 and published in English were included. A total of 37 full‐text studies were screened for inclusion, with 22 meeting inclusion criteria.ResultsAdvanced age, decreased mobility, constipation, extended length of stay, and multiple comorbidities were identified as non‐modifiable factors associated with inadequate bowel preparation. Narcotic use, failure to follow preparation instruction, and delayed time to colonoscopy were identified as modifiable factors associated with poor bowel preparation.ConclusionsEducational interventions and interprofessional programs, using a multifaceted approach, increase the odds of adequate bowel preparation, including nursing tip sheets, troubleshooting flowsheets, and bowel movement assessment scoring.
