Usability Evaluation of the Novel Smartphone Application, HPV Vaccine: Same Way, Same Day, Among Pediatric Residents.

OBJECTIVE

Scalable, deliberate practice training strategies to administer evidence-based recommendations are necessary to improve human papillomavirus (HPV) vaccination rates. We sought to characterize resident clinicians' perceptions regarding the usability of the HPV Vaccine: Same Way, Same Day smartphone application (app). Usability, a critical aspect of digital programs to promote behavior change, was evaluated.

METHODS

Fifteen third-year pediatric residents were recruited to complete a usability evaluation of the HPV Vaccine: Same Way, Same Day app, which includes simulated role-play scenarios in which users interact, as a pediatrician avatar, with an animated parent hesitant to accept the vaccine for her child. The app provides information about the vaccine and utilizes deliberate practice, a purposeful and systematic approach to improve performance, to teach evidence-based vaccine recommendation practices, including motivational interviewing skills. Data were derived from in-depth, semistructured interviews with pediatric residents. We used a constructivist general inductive approach to illuminate perspectives via inductive coding and pattern identification. Garrison's theoretical construct on self-directed learning was used to cluster themes into conceptual categories.

RESULTS

We classified interview data in 3 conceptual categories: self-management, internal monitoring and motivational principles. Residents described the app as interactive, easy to use, succinct, informative, engaging, and practical. All residents would recommend the HPV Vaccine: Same Way, Same Day app to a colleague. Residents suggested adding more complex cases for future iterations.

CONCLUSIONS

From their perspective, pediatric residents reported that an app using deliberate practice principles has the potential to inform and advance providers' counseling skills regarding the HPV vaccine.
