Appendicitis is a common surgical condition that frequently requires diagnostic imaging. Abdominal computed tomography (CT) is the gold standard for diagnosing appendicitis. Ultrasound offers a radiation-free modality; however, its availability outside business hours is limited in many emergency departments (EDs). The purpose of this study is to evaluate the test characteristics of emergency physician-performed point-of-care ultrasound (POCUS) to diagnose appendicitis in a Canadian ED.
Methods
A health records review was performed on all ED patients who underwent POCUS to diagnose appendicitis from December 1, 2010 to December 4, 2015. The sensitivity, specificity, and likelihood ratios were calculated. The gold standard used for diagnosis was pathology, laparoscopy, CT scans, and a radiologist-performed ultrasound.
Results
Ninety patients were included in the study, and 24 were diagnosed with appendicitis on POCUS. Ultimately, 18 were confirmed to have appendicitis through radiologist-performed imaging, laparoscopy, and pathology. The sensitivity and specificity of POCUS to diagnose appendicitis were 69.2% (95% CI, 48.1%-84.9%) and 90.6% (95% CI, 80.0%-96.1%), respectively.
Conclusion
POCUS has a high specificity for diagnosing acute appendicitis and has very similar characteristics to those of a radiologist-performed ultrasound. These findings are consistent with the current literature and have the potential to decrease patient morbidity, diagnostic delays, ED length of stay, and need for additional imaging.
The Joint Commission on Accreditation of Healthcare Organizations recommends that patients admitted to hospital with pneumonia receive their first dose of antibiotics within 6 hours of presenting to the emergency department (ED). Previous research in the United States indicates that rural hospitals may be better at achieving this benchmark than urban centres. This particular quality indicator has not yet been evaluated in Canada. The purpose of this study was to determine whether the target door-to-antibiotic (DTA) time of 6 hours or less could be met in a rural ED.
Methods:
We conducted a retrospective chart review of patients admitted to hospital with a diagnosis of pneumonia. Descriptive data for each case was collected, including demographic and timeline information. We analyzed DTA time, antibiotic type, route of administration, hospital length of stay and disposition at discharge.
Results:
We reviewed a total of 320 charts from Apr. 1, 2003, to Mar. 31, 2008. The final sample consisted of 143 patients (50.3% women) whose median age was 79 years. The median DTA time was 151 minutes and 81.8% of patients received their first dose of antibiotics within 6 hours. Patients received antibiotics either orally (47.6%), intravenously (47.6%) or both (4.8%). Single-agent respiratory fluoroquinolones were used 71.4% of the time. Median length of hospital stay was 4 days; most patients were discharged home (79.7%), 11 died, 11 were transferred and 7 were discharged to a nursing home.
Conclusion:
A DTA time of 6 hours or less is achievable in a rural ED.
The Canadian Emergency Cardiac Care Coalition, the American Heart Association and similar groups have established a benchmark for the administration of thrombolytics in acute myocardial infarction (AMI) care as a door-to-needle (DTN) time of 30 minutes or less. Previous research suggests that this goal is not being achieved in Canada. The purpose of this study was to determine whether the target DTN time of 30 minutes or less for thrombolysis could be met in 2 rural Ontario emergency departments (EDs).
Methods:
We conducted a retrospective chart review and obtained descriptive data for each case, including demographic information and the Canadian Emergency Department Triage and Acuity Scale (CTAS) score. Visit timeline data were also collected and included the time during which patients saw a physician, had an electrocardiogram (ECG), received thrombolytic therapy and were discharged from the ED. Relevant time intervals, such as the median DTN time, were calculated.
Results:
A total of 454 charts were reviewed for patients with a diagnosis of AMI who were seen between 1996 and 2007. The final sample consisted of 101 patients who received thrombolytics (63% men) whose median age was 67 years and median CTAS score was Level II (Emergent). The median door-to-ECG time was 6 minutes, door-to-physician time was 8 minutes and DTN time was 27 minutes; 58% of patients received thrombolytics within 30 minutes.
Conclusion:
A DTN time of 30 minutes or less is achievable in rural EDs.
