Knowledge, attitude, practices, and perceived barriers to using point-of-care ultrasound by Asian primary care physicians - a mixed method study.

backgroundAlthough research shows that point-of-care ultrasound is helpful in primary care, there is little research on point-of-care ultrasound use and the barriers to its use in Asia. This study estimated the prevalence of primary care physicians using point-of-care ultrasound in Hong Kong and assessed their perceived knowledge, attitude, practices, and barriers to using point-of-care ultrasound. STUDY

designThis was a mixed-method study: cross-sectional survey, followed by semi-structured interviews. Primary care physicians who were members of the Hong Kong College of Family Physicians and/or were clinical teachers affiliated with the Department of Family Medicine and Primary Care at the University of Hong Kong were invited to participate.

resultsA total of 330 and 14 completed the survey and interviews, respectively. The prevalence of respondents using point-of-care ultrasound was 22.5%. Perceived knowledge was fair (mean score: 1.9 out of 4; SD: 0.6). The attitudes were mostly positive (mean score: 3.0 out of 4; SD: 0.5). Majority stated that barriers to using point-of-care ultrasound were related to training (90.9%), the competence of point-of-care ultrasound skills (90.2%), and clinical support (89.5%). Qualitative data identified that most participants found point-of-care ultrasound useful; however, participants felt that its use was limited by their competence of point-of-care ultrasound and by factors related to their clinical practice.

conclusionsAlmost a quarter of respondents are using point-of-care ultrasound with a majority having positive attitudes. They lack confidence in their skills as knowledge is poor but simultaneously find training and clinic support limited.
