Riaz A, Cambaco O, Ellington LE, et al. - Since paediatric pneumonia burden and mortality are highest in low-income and middle-income countries (LMIC), researchers sought to assess the feasibility, usability and acceptability of lung ultrasound (LUS) through qualitative methods with healthcare providers (HCPs) and caregivers in Mozambique and Pakistan. In total, 21 HCPs and 20 caregivers were recruited. This was the first study assessing HCP and caregiver perspectives of paediatric LUS through qualitative analysis. Critical components impacting feasibility, usability and acceptability of LUS for paediatric pneumonia diagnosis in LMIC have been identified for initial deployment. Future research should explore the sustainability of LUS, with a specific focus on quality control, device maintenance and functionality, and the adoption of new technologies within the healthcare system. This study emphasises the importance of early engagement with both users and recipients of new technology early in order to adapt future interventions to the local context for successful implementation.
