Increasing use of immunization information systems for routine vaccinations in independent community pharmacies: A randomized controlled trial

Abstract

BackgroundOnly 60% of adults nationwide and just 36.8% of adults in Alabama have immunization data recorded in an Immunization Information System (IIS). The objective of this study, which took place before the coronavirus disease 2019 (COVID-19) pandemic, was to evaluate the impact of an IIS training program on pharmacists’ IIS enrollment, participation, awareness, knowledge, intention, and attitudes. MethodsA randomized controlled trial was conducted in 2019 among Alabama pharmacists (N = 41) practicing in independently owned pharmacies and providing vaccination services but whose pharmacy was not enrolled in Alabama’s IIS (Immunization Patient Registry with Integrated Technology [ImmPRINT]). Intervention pharmacists were offered a 2-hour IIS training program, including an online continuing pharmacy education article, demonstration videos, implementation guide, and informational flyer. Control pharmacies received the informational flyer only. Pharmacy-level outcomes, including enrollment and participation, were obtained from ImmPRINT administrative records. Pharmacist-level outcomes, including awareness, knowledge, intention, and attitudes, were self-reported using baseline, 1-month, and 3-month surveys. Two-way mixed analysis of variance, chi-square, and independent t tests were used to analyze differences in outcomes between and within groups. ResultsEnrollment in ImmPRINT was significantly greater among intervention pharmacists’ pharmacies (P = 0.035). In particular, 59.1% of intervention pharmacies compared with 26.3% of control pharmacies were enrolled in ImmPRINT at 3 months. No statistically significant differences were found between groups in terms of participation in ImmPRINT. Intervention pharmacists’ awareness of IIS was significantly greater than control pharmacists (P = 0.028) at 1 month (postintervention). Furthermore, the IIS training program significantly improved intervention pharmacists’ knowledge (P = 0.030) and attitudes (P = 0.016) toward IIS over 3 months compared with the control group. ConclusionsThis pharmacist-centered training program focused on practical strategies to integrate IIS into pharmacy workflow. Results show that pharmacists’ enrollment, awareness, knowledge, and attitudes significantly improved as a result of this training. As pharmacists become more involved in immunization efforts, particularly in response to COVID-19, awareness of and participation in responsible immunization documentation are critical.
