Factors Influencing Adequacy of Colon Cleansing for Colonoscopy in Hospitalized Patients: An Observational Prospective Multicentre Study and a Predictive Model

Background Inpatient status is an independent risk factor for inadequate colon cleansing for colonoscopy. The reasons for this have not been studied sufficiently. Findings This study identified setting-, patient-, and preparation-related factors independently associated with adequacy of colon cleansing. The authors derived and validated a predictive model and developed an app for clinical practice. Implications for patient care The identification of risk factors for inadequate colon cleansing, along with a model-derived app, might help clinicians identify inpatients who deserve extra efforts to meet quality standards for colonoscopy.
