Current perception and barriers to implementing lung ultrasound in Canadian neonatal intensive care units: a national survey

Despite the growing body of literature supporting the use of point-of-care lung ultrasound (POC-LU) in neonates, its adoption in Canadian neonatal intensive care units (NICUs) remains limited. This study aimed to identify healthcare providers’ perceptions and barriers to implementing POC-LU in Canadian NICUs. We conducted an electronic survey targeting neonatologists, neonatal fellows, neonatal nurse practitioners, and registered respiratory therapists in 20 Canadian NICUs. The survey comprised a 28-item questionnaire divided into four sections: (1) participants’ demographics and availability of POC-LU equipment, (2) experience and interest in POC-LU learning, (3) perception of POC-LU as a diagnostic tool, and (4) barriers to POC-LU implementation in NICUs. A total of 194 participants completed the survey, with neonatologists comprising the majority (45%). Nearly half of the participants (48%) reported prior experience with POC-LU. The most prevalent indications for POC-LU use were diagnosis of pleural effusion (90%), pneumothorax (87%), and respiratory distress syndrome (76%). Participants identified the primary barrier to POC-LU adoption as the lack of trained providers available for both training and clinical integration. Notably, most respondents (87%) expressed keen interest in learning neonatal POC-LU. A subgroup analysis based on the responses collected from NICU-directors of 12 institutions yielded results consistent with those of the overall participant pool.     Conclusion: This survey underscores the perceived importance of POC-LU among NICU healthcare providers. A Canadian consensus is required to facilitate the development of widespread training programs as well as standardized clinical practice guideline for its implementation. What is Known:• In recent years, point-of-care lung ultrasound (POC-LU) has emerged as an important tool in neonatology, revolutionizing the assessment and management of critically ill infants. However, its adoption in Canadian Neonatal Intensive Care Units remains limited.What is New:• Most Canadian healthcare providers showed high level of interest in learning POC-LU techniques. Additionally, POC-LU was perceived as a useful tool for diagnosis and guiding intervention in various neonatal respiratory diseases. Nonetheless, the lack of expertise emerged as the primary barrier to its adoption and practice across different groups of participants regardless of their clinical experience level.
