RESUMO
OBJECTIVE: To decrease the percentage of patients undergoing an abdominal radiograph for evaluation of constipation within 24 hours of their initial gastroenterology visit. STUDY DESIGN: In January 2015, we implemented a quality improvement, evidence-based guideline (EBG) aimed at standardizing the initial assessment of patients presenting for a new outpatient gastroenterology visit with a primary complaint of constipation. Over the subsequent 5 years, we followed the clinical impact of this guideline initiation with the goal of decreasing unnecessary abdominal radiograph use by 10% within 1 year of EBG launch. Patients older than 6 months and younger than 19 years were included. RESULTS: In total, 6723 patients completed new patient gastroenterology visits for a primary diagnosis of constipation between 2013 and 2019. Of these, 993 (14.8%) patients had abdominal radiographs taken within 24 hours of their initial visit. Over the 7 years of this project, a mean frequency of abdominal radiograph use decreased from 24% to less than 11%. In addition, a 57% decrease in hospital charges related to decreased radiograph use for constipation was found. No increases in subsequent emergency department visits or hospitalization for constipation within 30 days of patients' initial visits were seen. CONCLUSIONS: Through local adoption of an EBG, routine use of abdominal radiographs taken during a patient's initial outpatient gastroenterology visit for constipation decreased by more than 50%. This reduction was maintained over a subsequent 5-year period without any detrimental side effects.
