116 participants
Baseline compared to 6-9 months later.
2020-11-23
Participant Flow
10 facilities were to participate in the first 6 POCUS course session during FY17. 10 facilities were to participate in the last 6 POCUS course sessions during FY17. Participants, rather than facilities, were recruited and assigned to to the early or late intervention arms.

Early Intervention
This cohort of 10 facilities will undergo early training by participating in the first 6 POCUS course sessions during FY17. Although facilities are being recruited the intervention is taking place at the individual level. All reporting will be at the individual level.
|
Late Intervention
This cohort of 10 facilities will undergo late training by participating in the last 6 POCUS courses during FY17. Although facilities are being recruited the intervention is taking place at the individual level. All reporting will be at the individual level.

PRIMARY outcome
Timeframe: Baseline compared to 6-9 months later.Population: Participants who completed a provider survey both at the start and about 6-9 months later
Provider self-reported data pre- and post-intervention on frequency of point-of-care ultrasound use, based on number of exams per week.

SECONDARY outcome
Timeframe: Baseline compared to 6-9 months later.Population: Participants who completed a knowledge survey both at the start and about 6-9 months later were analyzed. Those who did not provide both surveys are not reported. Row populations may therefore differ from total population counts.
Provider knowledge will be tested pre- and post-intervention (at baseline \[pre-course\] and 6-9 months post-course). Knowledge Exam has a minimum of 0 points and a maximum of 30 points (1 pt per question). A higher score indicates more knowledge about POCUS. A positive change in score means a better outcome post-course (net increase in knowledge) compared to baseline.

Provider hands-on cardiac skills will be tested pre- and post-intervention (at baseline \[pre-course\], and 6-9 months post-course). The minimum score on the POCUS Cardiac Skills scale is 0 points and the maximum is 100 points. A higher score indicates more skill. A positive change in score means a better outcome post-course (net increase in skills) compared to baseline.

Change in percentage of providers who reported experiencing difficulty with maintaining POCUS skills pre-course compared to 6-9 months post-course. A positive percentage indicates more providers are experiencing this barrier post-course, which is not unexpected as more providers acquire POCUS skills.
