Abstract

Objective

This prospective cross-sectional study assesses the adequacy of the current South African emergency point-of-care ultrasound (EPCUS) core curriculum against the local burden of disease.

Method

Patients presenting to five Emergency Centres during July 2011 were eligible for inclusion. Patients under the age of 12, after-hour presentations, missing folders and folders with incomplete notes were excluded. Emergency physicians with EPCUS exposure were responsible for data collection. They were all blinded to the study's aim. Summary statistics describe the proportion of clinical cases and procedures for which EPCUS was used. One investigator assessed the adequacy of the curriculum by matching the clinical indications of each module with the presenting complaint and final diagnosis of each patient. The ultrasound modules were ranked according to the frequency of their clinical indications. κ-Statistics are reported on 10% randomly selected cases to quantify interobserver agreement.

Results

The study included 2971 patients. Ultrasound assisted with diagnosis in 384 (12.92%) patients and in 34 (1.14%) procedures. A total of 1933 EPCUS procedures were indicated in 1844 (66.07%) patients. The five most frequently indicated modules were pulmonary, musculoskeletal, cardiac, focused assessment with sonography of HIV/tuberculosis co-infection and renal. The interobserver agreement (κ) was 0.602 (95% CI 0.559 to 0.645).

Conclusions

This study was an attempt to ensure an evidence-based approach to assess the adequacy of the EPCUS core curriculum in South Africa. The results illustrate that our local burden of disease may require a change of the current core curriculum.
