Background: Hospitalized patients completing bowel preparation for colonoscopy typically have preparations of poorer quality when compared to outpatient populations.
Aims: Our study aimed to evaluate the effectiveness of a performance improvement program in improving colonoscopy preparation for an inpatient population.
Methods: We identified a cohort of adult patients (n = 641) undergoing an inpatient colonoscopy during a 12-month period at an academic medical center and compared a multifactor intervention group to a historical baseline group. During this 12-month period, a performance improvement program including use of a dedicated gastrointestinal nurse facilitator, implementation of standardized order sets, and introduction of split bowel preparations in the inpatient setting was made available to the cohort group.
Results: The primary outcome was quality of bowel preparation for colonoscopy as rated by endoscopists using the modified Aronchick scale. When comparing the baseline group to the intervention group, the rate of acceptable preparations, characterized as excellent, good, or adequate, increased from 69.9 to 78.9%, which was statistically significant (p < 0.001).
Conclusions: A comprehensive performance improvement program improved the quality of colonoscopy preparation among inpatients. The use of a dedicated gastrointestinal nurse facilitator, implementation of standardized order sets, and introduction of split bowel preparations are recommended in the inpatient setting for an effective bowel preparation.
