Barriers to Implementation of Opioid-Free Anesthesia by CRNAs
Four Midwestern University poster authors explored barriers to adoption of newer OFA techniques among their CRNA colleagues and found younger practitioners preferring OFA.
Opioid utilization has traditionally been the gold standard for pain management. Anesthesia providers have relied heavily on opioids to ensure patient comfort. However, opioid use throughout the perioperative period is associated with complications. Because of these risks, OFA techniques may be considered. While research supporting the use of OFA techniques is becoming more available, it is presently unknown what proportion of CRNAs have adopted OFA. Hypothesized barriers to OFA implementation are a lack of education regarding OFA techniques, a lack of equipment necessary to provide these services, and/or a perceived barrier of facility culture that is resistant to OFA implementation. This research aims to expand the current knowledge of OFA’s perceptions, identify the percentage of surveyed CRNAs who utilize OFA, and identify perceived barriers to OFA.
A 20-question electronic survey was distributed nationally to CRNAs. The lead author developed the survey tool based on clinical experience, noting barriers to opioid-free anesthesia, and a literature search. The survey was tested as a pilot survey and sent to Arizona CRNAs. Because of the lack of generalized data specific to CRNAs, hypothesized barriers to OFA were left broad. Questions were unchanged from the pilot study. A biostatistician analyzed completed responses. Survey variables were summarized and compared with a Chi-square test. Variables included practice model (independent versus collaborative), highest education level achieved, additional training, exposure to OFA techniques, and availability of materials needed to utilize OFA. Lastly, facility barriers to practice change, attitudes towards education on OFA’s benefits, and overall attitude on OFA were evaluated. Significance was determined by P < 0.05.
339 were completed responses, reflecting an 11. 7% response. Results that reached statistical significance are demonstrated in Table 1 (below).
The survey’s results demonstrate that CRNAs believe OFA techniques are beneficial, with younger practitioners preferring OFA. Additionally, most CRNAs surveyed utilize PNB techniques as an analgesic method in their practice, but only 38% of survey respondents felt they were competent in administering them. There was a large disparity in perception of competence between genders amongst CRNAs, with males reporting a higher competence. As education emphasizes newer anesthetic techniques, such as OFA and PNBs, novice providers may be more comfortable and familiar with these anesthesia techniques regardless of gender. The perception of competence based on gender was an unintended finding of this survey and will be explored in upcoming research. While many CRNAs believe there is a benefit to OFA, barriers to implementation remain. Since OFA techniques are newly emerging, some providers may not see a benefit in changing their practice. Further research addressing why some CRNAs with less exposure to OFA are hesitant to implement it into their practice may be beneficial. Creating a facility culture wherein OFA techniques are encouraged will promote more widespread adoption of OFA practice. Additional research regarding facility culture and the perception of competence of new anesthetic techniques may help remove additional barriers to OFA implementation.
