Asynchronous training for ultrasound-guided peripheral IV placement among critical care nurses

Teaching ultrasound (US) guidance for placement of peripheral intravenous (PIV) catheters requires significant time for synchronous didactic and hands-on training. The investigators assessed the feasibility of an asynchronous model for critical care nurses to learn the novel skill of US-guided PIV placement. Secondary outcomes included the percentage of successful attempts and number of sticks per attempt for anatomy versus US-guided approaches.

The investigators built a self-contained training cart for learners to practice and record their performance. Training occurred asynchronously. The learners recorded data from PIV attempts. Participants completed pre- and post-training surveys. Data from this prospective observational cohort was analyzed for descriptive and comparative statistics, using Kirkpatrick's Model for evaluation of this educational intervention.

During a 6 month period, 21 nurses completed the asynchronous training, with eight recording their PIV placements. 81.0% of the training occurred outside of a Monday to Friday 9AM-5PM period. There were 64 attempts by anatomy approach and 84 with US-guidance. The anatomic approach was successful in 35.9% of attempts with a mean of 1.5 sticks (SD 1.0, Range 1-5). The US-guided approach had a statistically significant greater rate of success (77.4%; p < 0.001) with a mean of 1.2 sticks (SD 1.2, range 1-2, p < 0.01). Participants reported increased confidence in US-guided PIV placement and enjoyment with this method of learning.

Asynchronous learning model with cart-based instruction and practice is a feasible means for nurses to learn US-guided PIV placement. Significant outcomes were seen across Kirkpatrick levels I-IV for educational outcome assessment.
