Participant Flow

Community pharmacies in Montgomery, Jefferson, Mobile, Tuscaloosa, Lee (AL) and San Bernadino, Riverside, Los Angeles, San Diego in CA were identified using Hayes Directory. Pharmacies were recruited via telephone with a maximum of 5 contact attempts. Eligible pharmacies must offer at least pneumococcal or herpes zoster vaccination service.

A randomized block design was used. Eligible community pharmacies within each block (AL and CA) were randomly assigned to each treatment group. Pharmacies with the same ownership were assigned to the same treatment group to prevent potential contamination.

Measure
Enhanced Immunization Delivery Model
Pharmacist-technician pairs employed by community pharmacies that are assigned to this arm will receive a) immunization update training, b) training by immunization experts to enhance immunization delivery model and foster practice change at the beginning of 6-month and c) regular feedback and clinical support for the period of 6 months. Enhanced immunization delivery model: Webinar and online training will be delivered to intervention pharmacist-technician pairs to discuss strategies that can be used to enhance immunization delivery model and how to integrate the new model into their routine practice. This intervention also includes feedback from immunization experts for the period of 6 months. Immunization update: Basic immunization update online webinar will summarize changes in immunization schedules.
Immunization Update
Pharmacist-technician pairs employed by community pharmacies that are assigned to the control arm will receive an immunization update training. They will not receive a training by immunization experts nor regular feedback and clinical support. Immunization update: Basic immunization update online webinar will summarize changes in immunization schedules.

SECONDARY outcome

Timeframe: 6 months

Population: The unit of analysis was the pharmacy, a representative of each pharmacy unit reported the outcome. Two of the enhanced pharmacy did not provide responses regarding strategies to promote immunization activities.

During the study, pharmacist-technician pairs engaged in on-going strategies used to advertise, market and assess non-seasonal immunization service processes. Of the total of 10 strategies possible, each pair selected strategies that they implemented. Results were reported by a representative from each pharmacy unit.
