1116 - AIMS-trained Residents Exhibit Specific Communication Skills in a Standardized Patient Model of Vaccine Hesitancy

Background: Vaccine hesitancy (VH) is one of the top 10 threats to global public health. While VH is common among parents, there are no accepted best practices for counseling, and training in this area is not required in residency. Strategies are needed to help providers address VH in practice.

Methods: The AIMS (Announce, Inquire, Mirror, Secure) Method for Healthy Conversations is a structured communication strategy that attempts to build trust between provider and patient (or parent), inviting receptivity to healthcare recommendations. To assess whether relatively inexperienced providers exhibit AIMS behaviors after training, blinded pediatric residents were pseudo-randomized to receive either AIMS or control training. Subjects underwent pre- and post-training clinical encounters with blinded standardized patients (SPs) portraying vaccine-hesitant parents; encounters were video-recorded and assessed by 3 blinded raters using the Vaccine Hesitancy Communication Assessment (VHCA) tool, which was developed by an iterative process and validated in pilot testing. Subject confidence was assessed pre- and post-training.

Results: Overall VHCA intraclass correlation was 0.273 for pre and 0.681 for post encounters (2-way mixed averages); reliability varied with AIMS phases. Fifty-eight subjects completed the protocol, and VHCA ratings for 29 subjects were available for this analysis. AIMS behaviors were more commonly detected among AIMS-trained subjects than control (median change in score [scale 0–30]=4.5 versus 0 for control) (Figure 1). Confidence improved in both groups (Figure 2). SPs perceived no differences between groups, nor between pre and post within groups, in aspects of subject performance such as respect, empathy, and promotion of trust (P=0.936 [ANCOVA]; partial eta-squared 0.0).Figure 1

Conclusion: Pediatric residents can be trained in AIMS behaviors, and an SP model of VH can be used to assess performance. AIMS training results in similar gains in self-confidence compared to control training. SP perceptions may be colored by their script, which in this case was to exhibit adamant vaccine refusal. Testing of AIMS training in longitudinal experimental scenarios and in real-world settings is warranted.
