Point-of-care ultrasound needs assessment in a paediatric acute care setting in Malawi

ObjectiveTo describe the use of point-of-care ultrasound (POCUS) in an acute-care paediatric setting in Malawi, including clinical indications, types of examinations and frequency of positive findings.MethodsRetrospective, cross-sectional study of a convenience sample of POCUS examinations performed in one tertiary referral hospital in Lilongwe, Malawi over 1 year. POCUS examinations were performed by Paediatric Emergency Medicine physician consultants as part of routine clinical practice and at the request of local clinicians. Images were saved along with the clinical indication and physician interpretation for quality review. Ultrasounds performed by the radiology department and those examinations that were technically faulty, missing clinical application or interpretation were excluded.ResultsIn total, 225 ultrasounds of 142 patients were analysed. The most common clinical indications for which examinations were completed were respiratory distress (23%), oedema (11.7%) and shock/arrest (6.2%). The most common examinations performed were cardiac (41.8%) and lung (15.1%), focused assessment with sonography in trauma (FAST; 12.9%) and ultrasound-guided procedural examinations (9.8%). Pathology was identified in 68% of non-procedural examinations. Cardiac examinations demonstrated significant pathology, including reduced cardiac function (12.8%), gross cardiac structural abnormality (11.8%) and pericardial effusion (10.3%).ConclusionsPOCUS was used for both clinical decision-making and procedural guidance, and a significant number of POCUS examinations yielded positive findings. Thus, we propose that cardiopulmonary, FAST and procedural examinations should be considered in future for the POCUS curriculum in this setting.
