Impact of implementing a technology platform in community pharmacies to increase adult immunizations rates

Implementation strategies to increase seasonal influenza vaccination among adults: A rapid scoping review

Many strategies have been applied to increase seasonal influenza vaccination; however, gaps in coverage remain. We synthesized the evidence on effectiveness of implementation strategies to increase seasonal influenza vaccination among U.S. adults. Studies performed from February 2010-August 2023 in the United States, focused on seasonal influenza vaccination, and measuring uptake and coverage were included. Guidance from Cochrane was followed. Interventions were mapped to Expert Recommendations for Implementing Change strategies. A total of 1,585 non-duplicate records were identified, full-text screening was performed for 353 records, and 51 studies met inclusion criteria. Among these studies, implementation strategies included those that engaged consumers, trained and educated stakeholders, and supported providers. Considerable heterogeneity was found in the study setting, populations, design, and methods. Substantial study variation limits the ability to conclude which strategies are most effective at increasing influenza vaccination uptake and coverage in U.S. adults.

Immunization information systems' implementation and characteristics across the world: a systematic review of the literature

INTRODUCTION

Immunization Information Systems (IISs) are essential public health tools, supporting the management and analysis of vaccination data to aid clinical and strategic decision-making.

METHODS

Following PRISMA guidelines, this systematic review investigated global state and operational characteristics of IISs. A comprehensive search across multiple databases up to 6 June 2023, identified 2,612 articles, with 238 included.

RESULTS

A significant increase in IIS research was observed in recent years, with a strong preference (84.5%) for electronic immunization registries (EIRs). Notably, 36% of IISs operate at the national level, and 47.7% meet the U.S. CDC definition, 17.0% are interoperable with personal health records, and 11.7% provide direct access to vaccination data for vaccinees or their guardians. Other key features include automated reminder systems for recipients and providers (12.1%), near real-time or real-time data entry (11.0%), the inclusion of demographic and socioeconomic data (16.7%), and the capacity to document vaccine refusal or hesitancy (10.2%).

CONCLUSIONS

IISs contribute to improving population-level surveillance of vaccine-preventable diseases. Persistent limitations related to data standardization, interoperability, and cost-effectiveness evaluation must be addressed. Strengthening these aspects is crucial to fully harness the potential of IISs in various healthcare settings, where enhanced vaccination tracking and targeting are most urgently needed.

Dutch Healthcare Professionals' Opinion on the Allocation of Responsibilities concerning Prescribing and Administering Medically Indicated Vaccines to Immunocompromised Patients

BACKGROUND

Specific vaccines are indicated for immunocompromised patients (ICPs) due to their vulnerability to infections. Recommendation of these vaccines by healthcare professionals (HCPs) is a crucial facilitator for vaccine uptake. Unfortunately, the responsibilities to recommend and administer these vaccines are not clearly allocated among HCPs involved in the care of adult ICPs. We aimed to evaluate HCPs' opinions on directorship and their role in facilitating the uptake of medically indicated vaccines as a basis to improve vaccination practices.

METHODS

A cross-sectional survey was performed among in-hospital medical specialists (MSs), general practitioners (GPs), and public health specialists (PHSs) in the Netherlands to assess their opinion on directorship and the implementation of vaccination care. Additionally, perceived barriers, facilitators, and possible solutions to improve vaccine uptake were investigated.

RESULTS

In total, 306 HCPs completed the survey. HCPs almost unanimously (98%) reported that according to them, the primary treating physician is responsible for recommending medically indicated vaccines. Administering these vaccines was seen as a more shared responsibility. The most important barriers experienced by HCPs in recommending and administering were reimbursement problems, a lack of a national vaccination registration system, insufficient collaboration among HCPs, and logistical problems. MSs, GPs and PHSs all mentioned the same three solutions as important strategies to improve vaccination practices, i.e., reimbursement of vaccines, reliable and easily accessible registration of received vaccines, and arrangements for collaboration among the different HCPs that are involved in care.

CONCLUSION

The improvement in vaccination practices in ICPs should focus on better collaboration among MSs, GPs, and PHSs, who should know each other's expertise; clear agreement on responsibility; reimbursement for vaccines; and the availability of clear registration of vaccination history.

Impact of pharmacist-led educational intervention on pneumococcal vaccination rates in cancer patients: a randomized controlled study

PURPOSE

This study aimed to evaluate clinical pharmacist's contribution to the pneumococcal vaccination rate by providing education to cancer patients in hospital settings.

METHODS

This study was conducted in 2 tertiary-care hospitals' medical oncology outpatient clinics. Patients over 18 years of age and diagnosed with cancer for less than 2 years, in remission stage, and have not previously received the pneumococcal vaccine were included. Patients were randomized to intervention and control groups. The intervention group was provided vaccination education and recommended to receive the PCV13 vaccine. The control group received routine care. Patients' knowledge about pneumonia/pneumococcal vaccine, Vaccine Attitude Examination Scale (VAX) score, and vaccination rates were evaluated at baseline and 3 months after the education.

RESULTS

A total of 235 patients (intervention: 117, control: 118) were included. The mean age ± SD was 57.86 ± 11.88 years in the control and 60.68 ± 11.18 years in the intervention groups. The numbers of correct answers about pneumonia/pneumococcal vaccine (p = 0.482) and VAX scores (p = 0.244) of the groups were similar at baseline. After the intervention, the median (IQR) number of correct answers in intervention group [10(3)] was higher than control group [8(4)] (p < 0.001). After the education, the total VAX score (mean ± SD) was less in intervention group (33.09 ± 7.018) than the control group (36.07 ± 6.548) (p = 0.007). Three months after the education, 20.2% of the patients in the intervention and 6.1% in the control groups were vaccinated with pneumococcal vaccine (p = 0.003).

CONCLUSIONS

The pneumococcal vaccination rate in cancer patients has increased significantly by the education provided by a clinical pharmacist in hospital settings.

Impact of pharmacist motivational interviewing on hepatitis B vaccination in adults with diabetes

BACKGROUND

In 2011, the Advisory Committee on Immunization Practices recommended hepatitis B (HepB) vaccination for previously unvaccinated adults (aged 19-59 years) with diabetes. Despite these recommendations, vaccination coverage for HepB vaccination for persons with diabetes remains low.

OBJECTIVES

The primary objective was to determine the impact of a community pharmacist-led motivational interviewing (MI) intervention on HepB vaccination initiation among adults with diabetes who were previously unvaccinated against HepB. The secondary objective was to describe HepB vaccination series completion among adults with diabetes who initiated the first dose of a HepB vaccine.

METHODS

A prospective, nonrandomized, controlled cluster trial was conducted across 58 regional grocery store chain pharmacies: a total of 29 pharmacies in the MI group and 29 pharmacies in the control group. Pharmacy location-level baseline data were collected during a 12-month pre-program period. The MI program was delivered over 10 months. Alerts were generated during prescription processing throughout the study period for eligible patients at each MI pharmacy location. The MI consisted of a face-to-face conversation between the pharmacist and the patient at the time of prescription pick-up. The difference in the primary outcome of HepB vaccination series initiation between patients receiving MI and control patients was assessed using a difference-in-differences analysis. For series completion, patients who initiated the HepB vaccination series were followed up for over 12 months after their first HepB vaccine dose.

RESULTS

There was a statistically significant 3.711% increase in HepB vaccination when comparing eligible individuals who received the MI intervention (n = 1569) to eligible individuals in the control group (n = 3640). Of the patients in the MI group who initiated HepB vaccination, 40 of 65 patients (61.5%) completed the vaccination series.

CONCLUSION

A pharmacist-led MI intervention increased HepB vaccination rates among adult patients with diabetes. Community pharmacists can effectively provide vaccinations that require multiple doses to complete the vaccination series.

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.

Determinants of COVID-19 Case Fatality Rate in the United States: Spatial Analysis Over One Year of the Pandemic

Background: The United States continues to account for the highest proportion of the global Coronavirus Disease-2019 (COVID-19) cases and deaths. Currently, it is important to contextualize COVID-19 fatality to guide mitigation efforts. Objectives: The objective of this study was to assess the ecological factors (policy, health behaviors, socio-economic, physical environment, and clinical care) associated with COVID-19 case fatality rate (CFR) in the United States. Methods: Data from the New York Times' COVID-19 repository and the Centers for Disease Control and Prevention Data (01/21/2020 - 02/27/2021) were used. County-level CFR was modeled using the Spatial Durbin model (SDM). The SDM estimates were decomposed into direct and indirect impacts. Results: The study found percent positive for COVID-19 (0.057% point), stringency index (0.014% point), percent diabetic (0.011% point), long-term care beds (log) (0.010% point), premature age-adjusted mortality (log) (0.702 % point), income inequality ratio (0.078% point), social association rate (log) (0.014% point), percent 65 years old and over (0.055% point), and percent African Americans (0.016% point) in a given county were positively associated with its COVID-19 CFR. The study also found food insecurity, long-term beds (log), mental health-care provider (log), workforce in construction, social association rate (log), and percent diabetic of a given county as well as neighboring county were associated with given county's COVID-19 CFR, indicating significant externalities. Conclusion: The spatial models identified percent positive for COVID-19, stringency index, elderly, college education, race/ethnicity, residential segregation, premature mortality, income inequality, workforce composition, and rurality as important ecological determinants of the geographic disparities in COVID-19 CFR.

Who receives influenza vaccinations at the Pharmacy? An analysis of the Texas Behavioral Risk Factor Surveillance System

INTRODUCTION

Vaccination helps to prevent influenza infection and reduce associated costs but the influenza vaccination rate in Texas for adults between the ages of 18 to 64 years old is the lowest in the US. Pharmacies and alternative locations have been shown to help increase vaccination rates but many adults still go unvaccinated.

OBJECTIVE

This research aims to determine the factors associated with obtaining influenza vaccination at the pharmacy compared to non-pharmacy locations in Texas.

METHOD

This study used pooled Texas Behavior Risk Factor Surveillance System datasets (2014 to 2018) for this assessment. The main outcome variable was categorized into pharmacy and non-pharmacy vaccination locations and analyzed using a logistic regression analysis. Further statistical analysis was done using a multinomial logistic regression after re-categorizing the outcome variable into pharmacy, doctor office, and other locations.

RESULT

Blacks were 63% (AOR 0.37, C.I. 0.26, 0.50) and Hispanics were 38% (AOR 0.62, C.I. 0.48, 0.80) less likely to receive influenza vaccinations at the pharmacy respectively when compared to Whites. Furthermore, those who did not live in a Metropolitan Statistical Area (MSA) were 33% (AOR 0.67, C.I 0.53, 0.84) less likely to receive influenza vaccinations at the pharmacy compared to those who lived in an MSA. While there was no observed difference in the likelihood of receiving influenza vaccination, the unemployed population were 40% (AOR 1.40, C.I 1.15, 1.71) more likely to be vaccinated in the pharmacy compared to the employed population.

CONCLUSION

There is potential for increased utilization of pharmacies as a source of influenza vaccination in Texas. Racial differences exist both for receiving influenza vaccinations and being vaccinated in the pharmacy. Influenza vaccination advocacy and education efforts may be necessary to improve pharmacy-based vaccination in Texas, especially for minorities and rural-dwelling Texans.

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

BACKGROUND

Project VACCINATE was a 1-year demonstration project conducted in 70 community pharmacies in Washington from September 1, 2016 to August 31, 2017 aimed at increasing adult vaccination and documentation in the state immunization information system (IIS). Key intervention features aligned with the Standards for Adult Immunization Practices and included incorporation of an immunization interface to facilitate proactive immunization screenings, patient engagement regarding vaccine needs, and vaccine documentation in the IIS as enhancements to the vaccination workflow.

OBJECTIVE

The objective of this qualitative study, a subanalysis of Project VACCINATE, was to identify community pharmacy staff members' perceptions of work system factors that influenced the implementation of key intervention features.

METHODS

Pharmacy staff at all Project VACCINATE locations were eligible to participate and were recruited by e-mail. Key informant interviews lasting 15-30 minutes were conducted by telephone using a semistructured interview guide. Interview transcripts were thematically analyzed using the Systems Engineering Initiative for Patient Safety (SEIPS) 2.0 model of work systems.

RESULTS

A total of 7 interviews were conducted with pharmacists from different pharmacy locations from September to December 2017. Nine factors emerged across all domains of the SEIPS 2.0 model regarding the implementation of the key intervention features. These factors were pharmacist-patient relationships, team culture, individualized patient education, technician involvement, electronic access to vaccine records, pharmacy layout, staff training, immunization documentation in other care settings, and insurance coverage.

CONCLUSIONS

Several key factors were identified that, when addressed, can enable the incorporation of proactive immunization screenings, patient engagement, and vaccine documentation as enhancements to the community pharmacy-based vaccination process. Community pharmacy organizations should consider incorporating the described factors into existing immunization programs when assessing the unique dynamics of their work system.

Increasing adult vaccinations at a regional supermarket chain pharmacy: A multi-site demonstration project

BACKGROUND

Millions of American adults do not receive the recommended vaccinations each year. Community pharmacies are well positioned to help fill this gap through easy access and innovative patient-centered interventions. The primary goal of this demonstration project was to implement new notification and motivational interviewing processes at a regional supermarket chain pharmacy to increase the number of influenza, pertussis, pneumococcal, and herpes zoster vaccines provided to adults.

METHODS

This prospective, observational project utilized a pre-post design. Algorithms were developed with pharmacy dispensing data to identify vaccine-eligible patients. Pharmacy staff then received automated notifications through one of the following: (1) a vaccine message printed on the prescription receipt or on paper attached to the prescription bag when patients came to the pharmacy; or (2) a patient list generated through commercially-available software listing patient contact information and which vaccine they were eligible to receive. Irrespective of the notification process, pharmacy staff employed motivational interviewing techniques either face-to-face or telephonic to engage patients in conversation about getting vaccinated. Finally, an interface to the statewide vaccination registry was developed and tested to transmit vaccination information from all pharmacy locations.

RESULTS

Ninety-nine pharmacies participated in the demonstration project across western Pennsylvania. A 33% increase in vaccinations was recorded over the prior year. Increases in vaccines were demonstrated in three of the four vaccine types: 45% for influenza, 31% for pertussis, and 7% for pneumococcal vaccinations. A decrease of 5% was observed for herpes zoster vaccinations. A successful connection to the statewide vaccine registry was established and 100% of all vaccines administered were transmitted to the registry.

CONCLUSION

A combination of face-to-face and telephonic interventions with motivational interviewing were successful at increasing adult vaccinations in a regional supermarket chain pharmacy. Equal and sustained prioritization for all vaccines is necessary to achieve increases across all vaccine types.

The essential role of pharmacists facilitating vaccination in older adults: the case of Herpes Zoster

Older adults share a disproportionately high burden of vaccine-preventable diseases. Despite recommendations from national and international health organizations, vaccination rates among older patients remain suboptimal, suggesting poor access and barriers to vaccination. Pharmacists are uniquely positioned to assist patients in overcoming many of these barriers. In this commentary, we describe some of the common barriers to vaccination that older adults encounter and the role pharmacists have in overcoming these barriers, in the US and abroad. We provide a case study of pharmacists' impact in supporting herpes zoster vaccination. We also identify areas of opportunities to promote further pharmacist involvement in vaccination efforts.
