Exploring the training, implementation and utilisation experiences of lung ultrasound accredited physiotherapists in the United Kingdom: A national survey

Background: With 10-years’ worth of growth in the use of LUS by physiotherapists within the U.K., this survey explores their training, implementation and clinical practice experiences. Methods: A cross-sectional survey was delivered to U.K. Physiotherapists accredited in LUS. The 50-question survey was administered via JISC online and was open for 4-weeks in January 2025. Closed questions were presented descriptively; open questions underwent inductive conceptual content analysis and descriptive coding. Results: Of the 223 invitations, 168 surveys were returned (75% response rate). Responses were highest from four U.K. regions which correlated with a higher number of regional mentors. Most respondents were in band 7 static roles, accredited via FUSIC^® and worked on the ICU with respiratory or surgical patients. The primary indication to perform a LUS was an increase in the fraction of inspired oxygen, average scanning frequency was 1–2 per week and common pathological findings were consolidation (pneumonia and atelectasis) plus pleural effusion (transudative and exudative). The most common negative factors experienced overall were limited time to scan and access to an US machine. Additional negative factors were limited access to a mentor during training, limited support from other professions during implementation, limited access to an appropriate patient population to scan during clinical practice. Conclusion: This is the largest survey to investigate the experiences of physiotherapists using lung ultrasound in the U.K. and provides important insights during training, implementation and clinical use. The specific details of these findings will support both current and future LUS users to plan and develop robust physiotherapy LUS service.
