Determinants to immunization information system implementation in independent community pharmacies

Immunization information systems (IISs) facilitate consolidated vaccination data within each state. Many have limited pharmacy participation, especially Alabama. As pharmacists increasingly engage in delivery of vaccines recommended across the life span, it is critical to understand the barriers to IIS implementation, particularly in rural community pharmacies where access to primary care may be limited.

The purpose of this study was to identify barriers and facilitators to IIS implementation in rural, independent community pharmacies in Alabama.

Qualitative interviews with rural, independent community pharmacy personnel and IIS experts in both states with high IIS participation and Alabama (state with low IIS participation) were conducted. States with high participation were identified as those with ≥75% of adults recorded in their respective state IIS. Less than 25% of Alabama adults were recorded in the state IIS at the time of this study. Deductive coding using CFIR constructs was conducted with a second coder to ensure inter-rater reliability. CFIR Rating Rules were applied to the coded data to allow for identification of constructs that have the greatest impact on implementation.

A total of twenty-five participants (16 pharmacy personnel; 9 IIS experts) were interviewed. During interviews, 32 of 39 CFIR constructs were mentioned and 11 constructs with a strong influence (+2 or -2) were identified. These included, "adaptability", "complexity", "compatibility", "available resources", "access to knowledge and information", "needs and resources of those served by the organization", "peer pressure", "external policy and initiatives", "knowledge and beliefs about the innovation", "engaging key stakeholders", and "engaging innovation participants".

This qualitative study explored perceived barriers and facilitators to IIS implementation in the rural, independent community pharmacy setting from the perspectives of pharmacy personnel and IIS experts. Factors identified can be used to inform the development of resources and implementation strategies to improve IIS uptake and participation.
