Enhancing adult immunization care by community pharmacists: A qualitative analysis of Project VACCINATE

Implementation of an adult life-course vaccine review service, VaxCheck, in community pharmacy: A qualitative analysis

BACKGROUND

Community pharmacists are well placed to identify and vaccinate unimmunized or under-immunized individuals who can put themselves and communities at risk of preventable disease. We designed and tested VaxCheck, a novel life-course vaccine review service that can be used to raise awareness and guide personal vaccination action plans, in community pharmacies in Ontario, Canada.

OBJECTIVE

To understand the experiences of community pharmacists and staff directly involved with providing the VaxCheck service as part of initial testing.

METHODS

Semi-structured interviews were performed with pharmacy staff from 9 pharmacies who participated in the study. Interviews were conducted at baseline and following each of 3 Plan-Do-Study-Act quality improvement cycles. Activities undertaken to perform VaxCheck were assessed. An inductive thematic analysis was performed to identify dominant themes and subthemes. Activities and descriptive codes were then correlated to the Consolidated Framework for Implementation Research (CFIR).

RESULTS

Twenty-six interviews were conducted. Pharmacy staff described VaxCheck activities as spanning 3 stages: (1) Promotion/offering of VaxCheck, (2) Completing the VaxCheck, and (3) Enacting recommendations and follow-up. VaxCheck activities were compatible with workflow related to delivery of other vaccines and medication reviews. Thematic analysis found 3 considerations guided VaxCheck adoption: (1) Aligning VaxCheck with workflow through flexible integration, (2) Enabling patient-oriented vaccination services, and (3) Contributing to community healthcare provision. Data aligned with all CFIR domains with strengths noted in constructs from the "Innovation characteristics" and "Individuals" domains. Barriers to implementation were identified in "Inner setting," "Outer setting," and "Process" domains, such as pharmacy workflow capacity, patient knowledge about vaccination, availability of vaccine records, and interactions with other healthcare providers.

CONCLUSION

Community pharmacists found VaxCheck to be a valuable, accessible service that was well-received by patients and supported adult vaccination reviews and individualized recommendations. VaxCheck was compatible with pharmacy workflow but needed additional resources for sustainability and promotion with stakeholders.

Challenges of vaccination information system implementation: A systematic literature review

Globally, healthcare services have begun to show interest in switching from paper-based to electronic-based vaccination records through Vaccination Information Systems (VIS). VIS have been implemented in various countries, but the study on the challenges of implementing VIS in these countries is still limited. The challenges of implementing VIS need to be understood to become a subject of discussion and anticipation by other countries that are just starting to implement VIS. We analyzed 32 selected publications from 634 initially retrieved. Fourteen challenges were successfully identified when implementing VIS, including interoperability, data quality, security and privacy, standardization, usability, internet connectivity, infrastructure, workflow, funding, government regulations, awareness, skeptical response, computer literacy, and staff-related challenges. The challenges of interoperability and data quality were found to be the most widely discussed by previous studies. In addition to identifying the challenges, this study includes a series of solutions that can be applied to overcome each challenge.

The impact of community pharmacy utilization of immunization information systems on vaccination rates: Results of a clustered randomized controlled trial

BACKGROUND

Adult immunization rates in the United States remain low. More convenient access to immunization information systems (IIS) may improve vaccination rates.

OBJECTIVE

The objective of this multilevel, clustered, randomized controlled study was to measure the impact of providing pharmacists with software and training to query IIS for patient vaccine history/recommendations on adult influenza, pneumococcal, herpes zoster, and Td/Tdap vaccination rates.

METHODS

California Rite Aid pharmacy districts were randomized into intervention/control groups using stratified randomization based on baseline influenza vaccination rates. Store demographic characteristics were collected at baseline (January 1-December 31, 2018). During follow-up (April 1, 2019-March 31, 2020), intervention group stores received access to ImmsLink, software that allows health care providers to review immunization records from IIS and identify a patient's recommended vaccinations. The difference-in-difference between intervention and control groups compared the changes in vaccination rates from baseline to follow-up by calculating adjusted ratios of risk ratios (RRRs). Analysis was performed at the store level.

RESULTS

Thirty-six districts comprising 501 Rite Aid stores (intervention: n = 244 stores; control: n = 257) were included. We found no significant differences in vaccination rates between groups: influenza, 19-64 years (adjusted RRR 0.99 [95% CI 0.83-1.17]); influenza, ≥65 years (1.02 [0.86-1.22]); herpes zoster (1.07 [0.90-1.28]); pneumococcal (0.95, 0.80-1.14); and Td/Tdap (0.88, 0.73-1.05). Reasons that recommended vaccines were not given in the intervention group included patient being deferred to future visit, patient declining, patient having already received the vaccination, patient declining because of cost, or vaccine being unavailable. Overall, pharmacist engagement with ImmsLink was low.

CONCLUSION

Providing pharmacists with software and training to query IIS did not improve vaccination rates compared with control pharmacies in this study. Factors such as an inconvenient interface or inadequate training or motivation may have caused low engagement with the software and should be considered in future interventions.

Helping Québec Pharmacists Seize the Vaccination Service Opportunity: The Pharmacy Best Practice Workshops

Vaccinations are a safe and effective way to protect against infectious diseases. The World Health Organization estimates vaccines have saved more lives than any other interventions and every year about two to three million deaths are averted worldwide through immunization. To improve vaccination coverage, pharmacists have been increasingly involved in immunization roles in their communities-as advocates, educators, and immunizers. Community pharmacy-based vaccination services have increased both in the number of immunization providers and the number of sites where patients can receive immunizations. In Canada, health care is under provincial legislation-and so, there are distinct differences in scope of pharmacist practice across the country. Prior to the COVID-19 outbreak in early 2020, in Québec, Canada's second-largest province, pharmacists did not have the authority to administer vaccines. To help prepare pharmacists in Québec to become immunizers, we developed and deployed a series of accredited workshops. In these facilitated workshops, pharmacists were able to share best practices that may lead to providing effective vaccination services, identify common competency gaps, discuss effective patient communication skills, and determine how to target the most vulnerable population groups. Participants were also asked to evaluate the workshop. Our results indicate the evaluation was very reliable in measuring participant satisfaction (Cronbach's α = 0.94) and pharmacists commented that the workshops' learning outcomes exceeded their expectations, and the topics covered were relevant and applicable. The evaluation also asked participants to identify weaknesses of training, so future educational interventions can be planned accordingly. We believe this work will contribute to the continual growth and advancement of the pharmacy profession in Canada.
