ABSTRACTObjectives:Unenhanced computed tomography (CT) has become a standard imaging technique for uncomplicated renal colic in many countries. The appropriate timing of CT imaging has not been established, and guidelines recommend that this imaging be performed between 1 and 7 days of presentation. The primary objective of this study was to determine the prevalence of alternative diagnosis identified with low-dose unenhanced CT in the emergency department (ED) in patients with suspected uncomplicated renal colic. ⋯ Conclusion:Low-dose unenhanced CT in the ED detects alternative diagnoses in 6% (95% CI 3-10) of patients with suspected uncomplicated renal colic, half of whom are subsequently hospitalized. Our prospective findings, which were similar to those reported in retrospective studies, are a potential argument for a systematic approach to ED imaging in suspected renal colic. Future research involving intervention and control groups would be helpful.

ABSTRACTBackground:One of the many challenges facing emergency departments (EDs) across North America is timely access to emergency radiology services. Academic institutions, which are typically also regional referral centres, frequently require cross-sectional studies to be performed 24 hours a day with expedited final reports to accelerate patient care and ED flow. ⋯ Our results indicate that the presence of a dedicated ED radiologist significantly reduces final report turnaround time and thus may positively impact the time to ED patient disposition. Patient care is improved when attending radiologists are immediately available to read complex films, both in terms of health care outcomes and regarding the need for repeat testing. Providing emergency physicians with accurate imaging findings as rapidly as possible facilitates effective and timely management and thus optimizes patient care.

ABSTRACTBackground:Low socioeconomic status (SES) is associated with adverse health outcomes. Possible explanations include differences in health status, access to health care, and care provided by clinicians. We sought to determine whether SES is associated with computed tomography (CT) use in the emergency department (ED). ⋯ For patients presenting with complex abdominal pain, no significant difference in CT use was observed. Conclusion:Lowest SES ED patients were less likely to receive CT scans overall and in headache and abdominal pain subgroups. No difference was seen among complex abdominal pain patients, suggesting that as clinical indications for the test become more clearcut, use across SES quintiles differs less.
