Addressing common barriers in adult immunizations: a review of interventions

Factors for the integration of prevention in primary care: an overview of reviews

BACKGROUND

The global burden of non-communicable diseases is increasing and the need for prevention is huge. Policies have yet to produce results and prevention indicators remain low. Primary care (PC) represents an opportunity to optimise the practice of prevention, but GPs are coming up against barriers that are holding back their prevention practices.

AIM

To identify the barriers and facilitators for the implementation of routine prevention practices in PC.

DESIGN & SETTING

This study is an international overview of reviews focusing on the integration of prevention in PC settings.

METHOD

The search was conducted in July 2022 using MEDLINE, Embase, Web of Science, and the Cochrane Database of Systematic Reviews. Included reviews are systematic reviews or scoping reviews adopting a systematic approach.

RESULTS

The 35 reviews included identify multiple barriers and facilitators related to the integration of prevention in PC. These factors are heterogeneous with regard to their source (the patient, the professional, and the health system) and their level of action (individual, organisational, or contextual). The results show the need to organise PC at the professional level (for example, in training), at the local level (for example, the information system), and at the political level (for example, the unclear definition of the role of professionals).

CONCLUSION

The factors influencing the integration of prevention in PC are multiple and act at different levels (individual, organisational, and health-system level). Organisation factors play a major role and seem to be a means of overcoming the difficulties encountered by healthcare professionals in developing preventive practices.

The COVID-19 Uninsured Program: Nearly 39 Million Vaccine Doses Were Funded, 2020-22

The COVID-19 Uninsured Program, administered by the Health Resources and Services Administration (HRSA), reimbursed providers for administering COVID-19 vaccines to uninsured US adults from December 11, 2020, through April 5, 2022. Using HRSA claims data covering forty-two states, we estimated that the program funded about 38.9 million COVID-19 vaccine doses, accounting for 5.7 percent of total doses distributed and 10.9 percent of doses administered to adults ages 19-64.

Effectiveness of patient reminders on influenza vaccination coverage among adults with chronic conditions: A feasibility study in Australian general practices

BACKGROUND

Influenza vaccination is recommended for Australians 18+ years old with medical risk factors, but coverage is suboptimal. We aimed to examine whether automatic, opportunistic patient reminders (SMS and/or printed) before appointments with a general practitioner increased influenza vaccination uptake.

METHODS

This clustered non-randomised feasibility study in Australian general practice included patients aged 18-64 years with at least one medical risk factor attending participating practices between May and September 2021. Software installed at intervention practices identified unvaccinated eligible patients when they booked an appointment, sent vaccination reminders (SMS on booking and 1 h before appointments), and printed automatic reminders on arrival. Control practices provided usual care. Clustered analyses adjusted for sociodemographic differences among practices were performed using logistic regression.

RESULTS

A total of 12,786 at-risk adults attended 16 intervention practices (received reminders = 4066; 'internal control' receiving usual care = 8720), and 5082 individuals attended eight control practices. Baseline influenza vaccination uptake (2020) was similar in intervention and control practices (∼34%). After the intervention, uptake was similar in all groups (control practices = 29.3%; internal control = 30.0%; intervention = 31.6% (p-value = 0.203). However, SMS 1 h before appointments increased vaccination coverage (39.3%, adjusted OR = 1.65; 95%CI 1.20;2.27; number necessary to treat = 13), especially when combined with other reminder forms. That effect was more evident among adults with chronic respiratory, rheumatologic, or inflammatory bowel disease.

CONCLUSION

These findings indicate that automated SMS reminders delivered at proximate times to appointments are a low-cost strategy to increase influenza vaccination among adults at higher risk of severe disease attending Australian general practices.

Factors Related to, and Effective Interventions for, Vaccination Uptake Among Older Adults in Two Asia-Pacific Countries: A Rapid Review

This rapid review aims to present a comprehensive overview of barriers, facilitators, and effective interventions that promote vaccination uptake by older adults in the Asia-Pacific region. Rapid review methodology was applied, using two databases (PubMed, Embase). Articles were included if studies were conducted in Australia, Singapore, Indonesia, and the Philippines; included human population ≥50 years of age, and was published from 2016 to August 2022. Related articles were not found from Indonesia and Philippines. A total of 23 articles met the inclusion criteria, with 19 reporting on barriers and facilitators, whereas, four articles reported effective interventions to promote vaccination uptake. Among the 19 studies that identified barriers and facilitators to vaccination uptake, the more common factors were social influences (n = 8/19), perceived benefits of vaccine (n = 7/19), and perceived vaccine safety (n = 6/19). Interventions that focused on supporting clinicians were found to be effective in leading them to recommend vaccinations among older adults, such as creating awareness on the low baseline vaccination rates among older adults, provision of structured health assessment, and nurse reminders. More studies are needed to ascertain the barriers and facilitators to uptake, as well as to identify effective interventions influencing vaccine uptake among older adults in the Asia-Pacific region.

Countering vaccine hesitancy: a systematic review of interventions to strengthen healthcare professionals' action

BACKGROUND

Vaccine hesitancy is relevant for healthcare professionals (HCPs) who face challenges in building trusting relationships with patients. Accordingly, the VAX-TRUST project has been developed to improve experiences of HCPs and patients dealing with vaccinations. To support VAX-TRUST, this work aimed to identify latest interventions targeted at HCPs to address hesitancy and increase vaccine uptake.

METHODS

A systematic review was conducted according to PRISMA by searching PubMed, Scopus and Embase. The protocol was registered on PROSPERO. Articles were eligible if evaluated interventions directly targeted at HCPs/healthcare students. The search was run on 26 January 2022. Articles published in 2016 or after were included.

RESULTS

A total of 17 492 records were identified; 139 articles were selected. Most articles were set in USA (n = 110). Over half had a pre-post design without a control group (n = 78). A total of 41 articles focused on single-component interventions, 60 on multi-component interventions involving only HCPs and/or students and 38 on multi-component interventions involving also other professionals. Main components were in-person education (n = 76), synchronous (n = 10) and asynchronous (n = 23) online learning, educational materials (n = 26), performance assessment and feedback (n = 33), electronic record changes (n = 30), role play/simulation (n = 21) and online games/apps (n = 5). Educational sessions were mainly about scientific update or communication. Outcomes of interventions were grouped in: vaccination rates (n = 69), knowledge (n = 32), attitudes (n = 26), confidence in counselling (n = 30) and acceptability (n = 16).

CONCLUSIONS

Apps, gaming, role play/simulations could represent innovative interventions. This review highlighted the need of delving into communication strategies and using more robust evaluations, longer follow-up and standardized measurements.

Drivers of and barriers to routine adult vaccination: A systematic literature review

We performed a systematic literature review in PubMed and Embase (2016-2021) to investigate the drivers of and barriers to routine vaccination in adults aged 50 and older globally. A thematic assessment identified three categories across 61 publications: sociodemographic, health-related, and attitudinal. The most common sociodemographic determinants (factors identified in studies; n = 47) associated with vaccination uptake were economic status, age, education, and household composition, which had mixed effects on vaccine uptake. For health-related determinants (n = 27), individuals with comorbidities and health care consumption were the most common factors, both increased vaccine uptake. The most common attitudinal factors (n = 42) were self-efficacy, provider or other's recommendations, and vaccine-preventable disease awareness; across studies, all attitude factors had a positive effect, unlike the sociodemographic and health status categories. Findings suggest that patient and provider awareness and education campaigns are effective ways to increase uptake of routine vaccinations in older adults.

Community pharmacists' participation in adult vaccination: A cross-sectional survey based on the theoretical domains framework

OBJECTIVES

This study aims to assess Qatar community pharmacists' practices in advocating and promoting adult vaccination and to characterize and quantify potential determinants of participation in adult vaccination as vaccine administrators, based on the theoretical domains framework (TDF).

METHODS

A cross-sectional survey of a randomly selected sample of community pharmacists in Qatar was conducted using a self-administered validated questionnaire. Items in the questionnaire on potential determinants of participation in adult vaccination were based on TDF. TDF items were subjected to principal components analysis.

RESULTS

In total, 271 respondents completed the questionnaire (67.7%). Most respondents (83.5%) did not have any previous training in vaccination administration and were not involved in any vaccine-related advocacy activities (78.9%). Principal components analysis of TDF items gave eight components: pharmacists' perceived knowledge and skills (median score of 22, interquartile range [IQR] 17-26, possible range: 7-35); perceived confidence (16; IQR 12-20, possible range: 5-25); perceived external support (9; IQR 7-11, possible range: 3-15); professional role identity (38; IQR 33-42, possible range: 11-55); emotions (10; IQR 9-12, possible range: 3-15); perceived consequences (22; IQR 18-24, possible range: 6-30); perceived usefulness (16; IQR 14-18, possible range: 4-20); and behaviour control (6; IQR 4-8, possible range: 2-10).

CONCLUSION

Pharmacists' perceived knowledge, skills, confidence and behavioural control are potentially important factors to address to facilitate participation in vaccination administration in Qatar. Along with providing vaccination training to community pharmacists, there is a need to change the current pharmacy practice structure to improve managerial and government support for and to equip pharmacies with resources for this role.

Adult vaccination uptake strategies in low- and middle-income countries: A systematic review

BACKGROUND

Evidence-based strategies can maximize vaccination intent and uptake among adults. This systematic review summarizes the existing literature on strategies to improve vaccination intent and uptake among adults in low- and middle-income countries (LMICs) to inform future implementation in various populations and contexts.

METHODS

Eligible studies were identified through a systematic search in Medline, Embase, Cochrane Libraries, as well as grey literature databases published between January 2010 and March 2021. The search was limited to studies in LMICs that evaluated adult vaccination interventions. Data were extracted from the included studies and evaluated against the World Health Organization's Behavioral and Social Drivers of Vaccination Framework. The National Institutes of Health study quality assessment tools were used to evaluate study quality.

RESULTS

The initial literature review identified 2,854 records, 22 of which met the inclusion criteria. The majority (n = 19 or 86%) of studies were from middle-income countries, with the remaining studies (n = 3 or 13%) set in low-income countries. The majority (15/22, 68%) of interventions were multi-component. 82% (18/22) of studies addressed thoughts and feelings, 59% (13/22) addressed social processes, and 73% (16/22) addressed practical issues. Five studies reported primary outcomes of vaccination intent, and the remaining 17 reported vaccine uptake. 36% (8/22) of the studies cited statistically significant positive intervention effects on vaccination intent or uptake. Few of the included studies (6/22, 27%) were RTCs, and most studies (15/22, 68%) were of poor study quality. The studies reporting the highest increase in vaccination intent and uptake were multi-component interventions that addressed all three determinants of vaccination.

DISCUSSION

The results of this review highlight levers that can be used to encourage vaccine intent and uptake in the ongoing rollout of COVID-19 vaccines, as well as the deployment of other vaccines to adult populations in LMICs. Of the included studies, multicomponent interventions were most effective, mainly when targeting multiple determinants of vaccination. However, poor study quality indicates the need for additional research to validate these findings.

Behavioural insights and the evolving COVID-19 pandemic

Behavioural sciences have complemented medical and epidemiological sciences in the response to the SARS-CoV-2 pandemic. As vaccination uptake continues to increase across the EU/EEA - including booster vaccinations - behavioural science research remains important for both pandemic policy, planning of services and communication. From a behavioural perspective, the following three areas are key as the pandemic progresses: (i) attaining and maintaining high levels of vaccination including booster doses across all groups in society, including socially vulnerable populations, (ii) informing sustainable pandemic policies and ensuring adherence to basic prevention measures to protect the most vulnerable population, and (iii) facilitating population preparedness and willingness to support and adhere to the reimposition of restrictions locally or regionally whenever outbreaks may occur. Based on mixed-methods research, expert consultations, and engagement with communities, behavioural data and interventions can thus be important to prevent and effectively respond to local or regional outbreaks, and to minimise socioeconomic and health disparities. In this Perspective, we briefly outline these topics from a European viewpoint, while recognising the importance of considering the specific context in individual countries.

Adult Vaccination in the United Arab Emirates—A Physicians' Knowledge and Knowledge Sources Study

Background

A lack of knowledge on adult vaccination has been documented among physicians. They play a critical role in promoting adult vaccines. This study aimed to review the status of adult vaccination in the United Arab Emirates (UAE) and evaluate physicians' knowledge and knowledge sources regarding adult vaccines.

Methods

Local, regional, and global adult vaccination guidelines were reviewed. A 40-item questionnaire was used to collect data from physicians from June to October 2020, using convenience and snowball sampling. Knowledge score was calculated, and predictors identified using Mann–Whitney U and Kruskal–Wallis H-tests. Ordinary Least Squares regression was used for Multivariate Analysis.

Results

A total of 500 responses were included. A quarter were internists, and another quarter were family physicians. Fifty-seven percent were medical interns and residents. Both perceived and actual knowledge of adult vaccination were low. Bivariate analysis showed knowledge depending on department, level of training, workplace, and perceived knowledge. All remained significant after multivariable regression except workplace. International and local guidelines were the most common knowledge sources. Forty-two percent were unable to access the local guidelines.

Conclusions

Physicians' knowledge was poor and local guidelines were not clear or easily accessible. Participants were highly receptive to guidance and practice with adult vaccines.

Factors and reasons associated with low COVID-19 vaccine uptake among highly hesitant communities in the US

BACKGROUND

The inability to achieve high COVID-19 vaccination rates can continue to have serious harm to our communities. Vaccine hesitancy is a major barrier towards high vaccination rates. We evaluated the relationship between COVID-19 vaccine uptake and vaccine hesitancy, and then examined whether community factors were associated with COVID-19 vaccine uptake and hesitancy.

METHODS

We constructed and evaluated a cross-sectional, county-level dataset that included the levels of vaccination uptake and vaccine hesitancy, and population characteristics based on those included in the CDC's Social Vulnerability Index.

RESULTS

Across 3142 US counties, vaccine hesitancy was significantly and negatively correlated with vaccine uptake rates (r = -0.06, P value <.01). The 2 predictors associated with a low vaccination level within highly hesitant communities were: no high school education (OR:0.70, P value <.001), and concern on vaccine availability and distribution (CVAC) (OR:0.00, P value <.001). The most common reason driving vaccine hesitancy was lack of trust in COVID-19 vaccines (55%), followed by concerns around side effects of the vaccine (48%), and lack of trust in government (46%).

CONCLUSIONS

COVID-19 vaccine hesitancy is a public health threat. Our findings suggest that low education levels are a major contributor to vaccine hesitancy and ultimately vaccination levels. Since education levels are not easily modifiable, our results suggest that policymakers would be best served by closing knowledge gaps to overcome negative perceptions of the vaccine through tailored interventions.

Facilitators of COVID-19 vaccine acceptance among Black and Hispanic individuals in New York: A qualitative study

BACKGROUND

Black and Hispanic individuals experience poorer outcomes related to coronavirus disease (COVID-19), yet have alarmingly lower uptake of the COVID-19 vaccine compared to non-Hispanic White individuals.

OBJECTIVE

To explore the perceptions of barriers and facilitators of COVID-19 vaccine acceptance among Black and Hispanic adults in the New York.

METHODS

A qualitative study consisting of one-on-one semistructured interviews with Black and/ or Hispanic adults in New York state was conducted. Participants were recruited from local businesses, community-based social service agencies and Black and Hispanic churches and a college. All data were collected between February and March 2021. Transcripts were analyzed using qualitative thematic analysis.

RESULTS

A total of 50 individuals (32 [64%] women; mean [SD] age, 42.04 [15.99] years) participated. The majority of participants identified as Black (n = 34, 68%), 9 (18%) identified as Hispanic, 3 (6%) as Black and Hispanic, and 4 (8%) as White and Hispanic. Twenty-two participants (44%) had high-school level education or less. Mistrust emerged as a central barrier to COVID-19 vaccine acceptance. Facilitators of effective COVID-19 vaccine messages include (1) key informants: like me, (2) personalized community outreach, (3) present the facts, and (4) communicate across multiple media platforms.

CONCLUSIONS

This qualitative study found that among Black and Hispanic participants, receipt of reliable vaccine related information, social networks, seeing people like themselves receive the vaccination, and trusted doctors are key drivers of vaccine acceptance.

Exploring the Scope and Dimensions of Vaccine Hesitancy and Resistance to Enhance COVID-19 Vaccination in Black Communities

BACKGROUND

The long history of distrust that characterizes the relationship between the Black/African-American population and the US Medical community makes COVID-19 vaccine hesitancy of great concern. A needs assessment of the Black/African-American community assessed willingness and explored the perceptions of community members regarding COVID-19 vaccination.

METHODS

The study used a mixed-methods approach. Respondents (n = 183) were surveyed with a web-based questionnaire. They were asked whether there would get vaccinated for COVID-19 barring any access or cost-related challenges. Perceptions of community members regarding vaccination were explored through one-on-one interviews (n = 30) and eight focus groups (n = 49), with participants drawn from across various demographic characteristics. Survey responses were summarized using frequencies and proportions. A thematic analysis was conducted on the qualitative data.

RESULTS

Thirty-four percent of respondents indicated "Yes" (willing to get vaccinated); 26.8% indicated "No", while 37.1% expressed hesitancy ("Maybe" or "I don't know"). Themes emerging from the qualitative data are grouped into three broad categories: vaccine accessibility (transportation, information, navigating healthcare system); vaccine hesitancy (with sub-categories of compliance, complacency and confidence); and vaccine "resistance" (conspiracy theories, conflicting beliefs, distrust of Government, trustworthiness of Health care).

CONCLUSION

Findings demonstrate a nuanced expansion of "vaccine hesitancy" to delineate groups with varying issues and perspectives. Interventions to enhance vaccination rates in Black/African-American communities should incorporate components that assure accessibility at the minimum, but also address non-access-related issues. Priority should be given to enhancing vaccine literacy, information-sharing as efficacy and safety data emerge, and addressing specific concerns identified through community-engaged outreach efforts.

Understanding and addressing vaccine hesitancy in the context of COVID-19: development of a digital intervention

OBJECTIVES

Severe Acute Respiratory Coronavirus 2 (SARS-CoV-2) was identified in late 2019, spreading to over 200 countries and resulting in almost two million deaths worldwide. The emergence of safe and effective vaccines provides a route out of the pandemic, with vaccination uptake of 75-90% needed to achieve population protection. Vaccine hesitancy is problematic for vaccine rollout; global reports suggest only 73% of the population may agree to being vaccinated. As a result, there is an urgent need to develop equitable and accessible interventions to address vaccine hesitancy at the population level.

STUDY DESIGN

& Method: We report the development of a scalable digital intervention seeking to address COVID-19 vaccine hesitancy and enhance uptake of COVID-19 vaccines in the United Kingdom. Guided by motivational interviewing (MI) principles, the intervention includes a series of therapeutic dialogues addressing 10 key concerns of vaccine-hesitant individuals. Development of the intervention occurred linearly across four stages. During stage 1, we identified common reasons for COVID-19 vaccine hesitancy through analysis of existing survey data, a rapid systematic literature review, and public engagement workshops. Stage 2 comprised qualitative interviews with medical, immunological, and public health experts. Rapid content and thematic analysis of the data provided evidence-based responses to common vaccine concerns. Stage 3 involved the development of therapeutic dialogues through workshops with psychological and digital behaviour change experts. Dialogues were developed to address concerns using MI principles, including embracing resistance and supporting self-efficacy. Finally, stage 4 involved digitisation of the dialogues and pilot testing with members of the public.

DISCUSSION

The digital intervention provides an evidence-based approach to addressing vaccine hesitancy through MI principles. The dialogues are user-selected, allowing exploration of relevant issues associated with hesitancy in a non-judgmental context. The text-based content and digital format allow for rapid modification to changing information and scalability for wider dissemination.

The need for pertussis vaccination among older adults and high-risk groups: a perspective from advanced economies of the Asia Pacific region

INTRODUCTION

Influenza and pneumococcal vaccines are the most regularly prescribed vaccines amongst adults <65 years of age. Pertussis booster vaccines (available as combined diphtheria-tetanus-acellular pertussis, Tdap) uptake is relatively low in many countries in the Asia-Pacific region. Increasing Tdap vaccination is a strategy that may aid healthy aging.Areas Covered: Epidemiology data, including notification reports from 6 advanced economies in Asia (Australia, Hong Kong, New Zealand, Singapore, South Korea, and Taiwan) were reviewed to assess the pertussis disease burden and identify high-risk groups. Existing Tdap vaccination recommendations were reviewed. Current vaccination practices were discussed to benchmark and identify barriers and success factors for Tdap booster vaccination in older adults.Expert Opinion: The available evidence supports Tdap vaccination at an individual level for the prevention of pertussis, along with tetanus and diphtheria in those aged 65+ years, together with influenza and pneumococcal vaccination. Data gaps need to be filled to support the development of national/supranational recommendations for pertussis booster vaccination. Groups at higher risk of pertussis infection and its complications, including those with chronic obstructive pulmonary disease and asthma, could be considered as priority groups. Increasing disease awareness and establishing adult vaccination registries could improve vaccine coverage and promote healthy aging.

Healthcare workers' perceptions and experiences of communicating with people over 50 years of age about vaccination: a qualitative evidence synthesis

BACKGROUND

Infectious diseases are a major cause of illness and death among older adults. Vaccines can prevent infectious diseases, including against seasonal influenza, pneumococcal diseases, herpes zoster and COVID-19. However, the uptake of vaccination among older adults varies across settings and groups. Communication with healthcare workers can play an important role in older people's decisions to vaccinate. To support an informed decision about vaccination, healthcare workers should be able to identify the older person's knowledge gaps, needs and concerns. They should also be able to share and discuss information about the person's disease risk and disease severity; the vaccine's effectiveness and safety; and practical information about how the person can access vaccines. Therefore, healthcare workers need good communication skills and to actively keep up-to-date with the latest evidence. An understanding of their perceptions and experiences of this communication can help us train and support healthcare workers and design good communication strategies.

OBJECTIVES

To explore healthcare workers' perceptions and experiences of communicating with older adults about vaccination.

SEARCH METHODS

We searched MEDLINE, CINAHL and Scopus on 21 March 2020. We also searched Epistemonikos for related reviews, searched grey literature sources, and carried out reference checking and citation searching to identify additional studies. We searched for studies in any language.

SELECTION CRITERIA

We included qualitative studies and mixed-methods studies with an identifiable qualitative component. We included studies that explored the perceptions and experiences of healthcare workers and other health system staff towards communication with adults over the age of 50 years or their informal caregivers about vaccination.

DATA COLLECTION AND ANALYSIS

We extracted data using a data extraction form designed for this review. We assessed methodological limitations using a list of predefined criteria. We extracted and assessed data regarding study authors' motivations for carrying out their study. We used a thematic synthesis approach to analyse and synthesise the evidence. We used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach to assess our confidence in each finding. We examined each review finding to identify factors that may influence intervention implementation and we developed implications for practice.

MAIN RESULTS

We included 11 studies in our review. Most studies explored healthcare workers' views and experiences about vaccination of older adults more broadly but also mentioned communication issues specifically. All studies were from high-income countries. The studies focused on doctors, nurses, pharmacists and others working in hospitals, clinics, pharmacies and nursing homes. These healthcare workers discussed different types of vaccines, including influenza, pneumococcal and herpes zoster vaccines. The review was carried out before COVID-19 vaccines were available. We downgraded our confidence in several of the findings from high confidence to moderate, low or very low confidence. One reason for this was that some findings were based on only small amounts of data. Another reason was that the findings were based on studies from only a few countries, making us unsure about the relevance of these findings to other settings. Healthcare workers reported that older adults asked about vaccination to different extents, ranging from not asking about vaccines at all, to great demand for information (high confidence finding). When the topic of vaccination was discussed, healthcare workers described a lack of information, and presence of misinformation, fears and concerns about vaccines among older adults (moderate confidence). The ways in which healthcare workers discussed vaccines with older adults appeared to be linked to what they saw as the aim of vaccination communication. Healthcare workers differed among themselves in their perceptions of this aim and about their own roles and the roles of older adults in vaccine decisions. Some healthcare workers thought it was important to provide information but emphasised the right and responsibility of older adults to decide for themselves. Others used information to persuade and convince older adults to vaccinate in order to increase 'compliance' and 'improve' vaccination rates, and in some cases to gain financial benefits. Other healthcare workers tailored their approach to what they believed the older adult needed or wanted (moderate confidence). Healthcare workers believed that older adults' decisions could be influenced by several factors, including the nature of the healthcare worker-patient relationship, the healthcare worker's status, and the extent to which healthcare workers led by example (low confidence). Our review also identified factors that are likely to influence how communication between healthcare workers and older adults take place. These included issues tied to healthcare workers' views and experiences regarding the diseases in question and the vaccines; as well as their views and experiences of the organisational and practical implementation of vaccine services.

AUTHORS' CONCLUSIONS

There is little research focusing specifically on healthcare workers' perceptions and experiences of communication with older adults about vaccination. The studies we identified suggest that healthcare workers differed among themselves in their perceptions about the aim of this communication and about the role of older adults in vaccine decisions. Based on these findings and the other findings in our review, we have developed a set of questions or prompts that may help health system planners or programme managers when planning or implementing strategies for vaccination communication between healthcare workers and older adults.

Spinning the globe from west to east: A mixed-method study to examine the impact of pharmacists on immunization advocacy and delivery in Asia Pacific

BACKGROUND

Global effort is key to prevent and control infections effectively. Whereas pharmacists' involvement in the immunization neighborhood, collaborative effort to meet immunization needs of the public, has reduced burden of vaccine-preventable diseases in Western countries, the impact of pharmacist-involved vaccination advocacy and delivery in Asia Pacific remains unclear.

OBJECTIVE

To examine the evidence for impact of pharmacists on immunization advocacy and delivery in Asia Pacific and to assess Singaporean pharmacists' experience in becoming immunizing pharmacists through the American Pharmacists Association's Pharmacy-based Immunization certificate training program.

METHODS

A mixed-method study consisted of systematic review and survey was conducted. The systematic review was conducted by searching PubMed and Cumulative Index to Nursing and Allied Health databases from inception to March 2021. Randomized controlled trials and observational studies related to pharmacist-involved immunization advocacy and training conducted in Asia Pacific were included. Eligible studies were appraised for quality using CONsolidated Standards of Reporting Trials (CONSORT) and STrengthening the Reporting of OBservational checklists. In addition, a 20-item Likert-scale survey evaluated the pharmacists' experience in becoming immunizing pharmacists in Singapore. Frequencies of each response to the survey items were analyzed.

RESULTS

Six studies were eligible for inclusion; 2 assessing impact of pharmacist as immunizer, 3 reporting outcomes of pharmacist-involved vaccine advocacy, and 1 evaluating the structure of pharmacist immunization training. Although study quality was minimal, all studies echoed positive findings as a result of pharmacist-provided immunization advocacy and delivery. Of the 23 pharmacists completing the survey, 91.3% strongly agreed that quality training was important to become immunizing pharmacists.

CONCLUSION

Although limited in number, studies conducted in Asia Pacific reported increased vaccination rates when involving pharmacists. Coupled with the enthusiasm to be trained in immunization advocacy and delivery as elucidated by the Singaporean pharmacists, pharmacists in Asia Pacific should also be advocated for their role in the immunization neighborhood as part of the global effort against vaccine-preventable infectious diseases.

How involvement of community pharmacies improves accessibility to and awareness about flu vaccination? - An example from Estonia

BACKGROUND

In Estonia, seasonal influenza vaccination coverage is poor, being in recent years the lowest in the older age groups. In 2018 the flu vaccination was first provided at community pharmacies in Estonia. The aims of this study were to evaluate the experience of flu vaccination at community pharmacies by pharmacy customers and to learn about the perception of community pharmacists regarding the immunization service.

METHOD

Two cross-sectional surveys: among pharmacy customers after receiving flu vaccination (n = 257), and for pharmacy professionals (n = 209). Descriptive statistics were calculated in both studies.

RESULTS

In the pharmacy customers` study, 54.9% received flu vaccination for the first time. Most of the respondents (96.8%) were satisfied with the quality of service. In both studies, community pharmacies were described as an accessible and convenient setting for immunization. Age and working experience of pharmacy professionals influenced the readiness to provide flu immunization, with younger pharmacists (<36 years) keener to be involved in vaccination services (p < 0.01).

EXPERT OPINION

Increasing influenza vaccination in high-risk patient groups is crucial. The involvement of other healthcare professionals, such as community pharmacists, could be key to reaching these patient groups and improving access to vaccination services in general. The development of the pharmacy profession has also shifted from pharmaceutical product based to patient oriented approach with provision of more clinical services. This enables to use professional competency of pharmacists in healthcare more widely. Lack of resources (financial, healthcare professionals, etc.) and an aging population are driving new ways to deliver healthcare more efficiently with the pharmacist working with other healthcare providers taking greater responsibility for patient health outcomes.

CONCLUSION

Vaccination service at community pharmacy has a great potential to expand flu immunization coverage in Estonia. Despite on pharmacy professionals are not allowed to provide vaccination service at the moment, their contribution to increase public awareness about flu vaccination is significant.
