- W2979235842 abstract "Introduction: Inpatient status is a known risk factor for inadequate bowel preparation (IBP) for colonoscopy; potential risk factors for and impact of IBP are unclear. Aims: 1) determine the quality of bowel preparations for inpatient colonoscopy, 2) assess impact of IBP on procedure delays, length of stay (LOS), and repeat colonoscopy, and 3) identify potential risk factors for IBP. Methods: This IRB-approved retrospective cohort study was conducted at a single academic teaching institution. All patients age >18 years who underwent an inpatient colonoscopy over an 8-month period (01/2013-08/2013) were included. IBP was defined as patients with a preparation described as “Poor” or “Unsatisfactory” or when colonoscopy was delayed ≥1d due to poor preparation. Optimal bowel preparation (OBP) was defined as patients with “Adequate,” “Good” or “Excellent” preparation without delay. Patients with a “Fair” preparation were excluded in the analysis of potential risk factors. Results: A total of 300 patients (median age 57±17.6, 50.3% male) were identified. At colonoscopy, 48% had an excellent/good/adequate preparation; 32% a fair preparation; and 20% a poor/unsatisfactory preparation. Only 43% met criteria for an OBP. Due to poor preparation, 14 (4.7%) patients required a repeat inpatient colonoscopy and 11 patients (3.7%) were recommended to undergo repeat outpatient colonoscopy within 1 year. Twenty-three patients (7.7%) had a delay in colonoscopy (median 1 day, range 1-3) due to IBP, 3 with a poor preparation after delay. In total, 79 (26%) patients had an IBP. LOS was greater in patients with an IBP (13.5±16.3 days) than those with an OBP (10.0±14.4 days, p=0.05). Patients taking tricyclic antidepressants (TCA) or opiates (OR 2.00, CI 1.10-3.50) and those admitted to surgical service (OR 2.49, CI 1.00-6.20) had a significantly higher rate of IBP (Table). Patients undergoing colonoscopy in the afternoon (p=0.06) and those with an ASA ≥3 (p=0.10) had a trend towards a higher rate of IBP. Conclusion: In this large cohort, IBP occurs in 26% of inpatient colonoscopies and procedure delays occur in 8%; patients with IBP have an overall increased LOS. Risk factors for IBP include opiate/TCA use and admission to a surgical service and possibly afternoon cases and ASA class ≥3. These populations should be targeted for quality improvement efforts to limit the significant financial and clinical impact of IBP. Disclosure - Dr. Johnston - No financial disclosures.
