Background:
The opioid epidemic remains a major public health crisis in the United States. Over 100,000 opioid overdose deaths were reported in 2023, and perioperative opioid use contributes to misuse and chronic dependence. In anesthesia practice, opioids are administered to manage surgical pain but are associated with adverse effects, including respiratory depression, hyperalgesia, nausea, and prolonged recovery. Multimodal anesthesia and regional anesthesia techniques have been implemented in practice to reduce opioid requirements and improve patient outcomes. However, successful implementation depends on provider knowledge and clinical confidence, particularly among Student Registered Nurse Anesthetists (SRNAs).
Purpose/Specific Aims:
This project aimed to identify knowledge deficits and perceived barriers among SRNAs enrolled in accredited U.S. nurse anesthesia programs regarding multimodal anesthesia, with a specific focus on ultrasound-guided regional anesthesia. A secondary aim was to develop and evaluate a cognitive aid designed to enhance knowledge, confidence, and clinical application.
Methods:
A needs assessment was conducted through the distribution of a student survey with both Likert-scale evaluations and qualitative feedback. Data collection assessed educational exposure, perceived competence, and barriers to performing regional techniques. A user-centered design process aided in the development of a cognitive aid prototype. A post-survey was distributed to assess the cognitive aids usability clinically and evaluate usefulness of clinical information.
Results:
SRNAs report moderate exposure but low to moderate confidence in ultrasound-guided nerve blocks, with identified barriers including anatomical knowledge gaps, medication dosing uncertainty, and limited hands-on experience. Implementation of a cognitive aid improved self-reported confidence scores, increased knowledge retention, and enhanced education on ultrasound-guided techniques.
Conclusion:
Addressing SRNA knowledge deficits through the development of cognitive aid has strengthened regional anesthesia competence and promoted multimodal pain practices.
