Abstract
PURPOSE: The aim of this project was to reduce abdominal ultrasound examinations in patients who had undergone abdominal CT within 72 hours previously.
METHODS: A best practice advisory (BPA) was created in the electronic medical record to advise against the use of abdominal ultrasound in adult inpatients and emergency department patients who had undergone abdominal CT within the preceding 72 hours. Acceptable acknowledgment reasons to proceed with the order were made available if providers chose to override. Frequency of BPA firing and subsequent ordering behavior were evaluated 6 months after integration of the BPA into the electronic medical record. Chart review was conducted for 100 patients whose orders were placed through an override of the alert to determine if the ultrasound study added value and for all patients whose ultrasound studies were canceled to confirm that patient care was not compromised by omitting the ultrasound study.
RESULTS: In the first 6 months, a total of 614 inpatient and emergency department abdominal ultrasound orders triggered the BPA. A total of 16% of orders (n = 96) were canceled by the provider after the BPA, reflecting 518 overrides. The majority of retained orders were to evaluate the gallbladder (44% [227 of 518]). Chart review confirmed utility for gallbladder imaging and that the canceled ultrasound examinations would not have contributed value to patients' care.
CONCLUSIONS: A recently performed abdominal CT scan may obviate the need for inpatient and emergency department abdominal ultrasound, particularly in the setting of hospital-acquired acute kidney injury. A BPA resulted in only 16% of orders' being canceled, whereas chart review revealed a much larger opportunity to avoid duplicative imaging.
