An international survey exploring the adoption and utility of diagnostic lung ultrasound by physiotherapists and respiratory therapists in intensive care.

Introduction: Lung ultrasound (LUS) is an emerging assessment tool for intensive care unit (ICU) therapists (physiotherapists, physical therapists and respiratory therapists) to aid pathology identification, intervention selection, clinical reasoning and as an outcome measure to assess intervention efficacy. However, the extent of LUS adoption and use by ICU therapists internationally has not been described in the literature. Objectives: This survey explored the interest in LUS amongst ICU therapists internationally. In addition, LUS training, use in clinical practice and barriers to implementation were also explored. The survey findings were used to facilitate recommendations for future adoption. Methods: International ICU therapists were invited to answer a 37 question cross-sectional open e-survey, distributed using the online survey tool REDCap Results: Three hundred twenty ICU therapists from 30 countries responded with most respondents coming from either the United Kingdom ( Conclusions: To the authors' knowledge this is the first study to explore the international adoption and utility of LUS by ICU therapists. LUS is a growing technique with widespread interest from ICU therapists internationally with a desire to adopt LUS into their assessments and upskill their practice. ICU therapists' use of LUS could allow more targetted and appropriate treatment for patients on ICU. Barriers to LUS adoption could be mitigated by having access to quality training programmes and mentorship. Development of profession specific guidance and policies within local infrastructure should facilitate growth and ensure robust quality assurance and governance processes.
