Point of care ultrasound (PoCUS) in low- and middle-income countries

Abstract

Point-of-Care Ultrasound (PoCUS) is a portable, affordable, and versatile diagnostic and procedural tool that enhances bedside decision-making. Its simplicity and safety make it especially valuable in low- and middle-income countries (LMICs), where access to advanced imaging is limited. PoCUS helps bridge diagnostic gaps by enabling real-time, noninvasive assessment and procedural guidance across anesthesiology, perioperative care, critical care, and emergency-medicine. However, implementation in LMICs faces barriers such as limited device availability, high costs, maintenance difficulties, and insufficient training. Equipment availability, accessibility and structured education remain key determinants of adoption. Training programs are often short-term and externally led, with limited long-term integration into local systems. Emerging strategies including “train-the-trainer” approaches, blended learning, and tele-mentoring—offer scalable solutions. Coordinated efforts across access, education, and sustainability—supported by mentorship and standardized credentialing—are essential. Ultimately, PoCUS represents more than a diagnostic tool; it is a driver of equity, safety, and empowerment in global health.
