Dalal Youssef<fnref n="1" />,²* ID, Linda Abou-Abbas³,⁴ ID, Suzan Farhat⁵ and Hamad Hassan⁶

**Abstract**

**Background:** Since the focus of healthcare has shifted toward prevention, pharmacists were highly encouraged to expand their practice to include immunization services. Our study aimed to assess the knowledge, attitudes and beliefs of community-based Lebanese pharmacists, in addition to their willingness to expand their practice scope to include vaccine administration.

**Methods:** A cross-sectional study was conducted during the phase preceding the arrival of the COVID-19 vaccine in Lebanon between 1 and 31st December 2020. Using a stratified random sampling method, data were collected from Lebanese community pharmacists (CPs) through an online survey that included information on socio-demographic characteristics, clinical experience, willingness to administer vaccines, knowledge about vaccination, attitudes towards immunization, reasons supporting utilizing pharmacists as immunizers and the requested elements to incorporate immunization in pharmacists' practice scope. Multivariable analyses were performed to identify the factors associated with knowledge.

**Results:** A total of 412 community pharmacists participated in this survey. Of the total, 66.5% of the surveyed CPs are willing to administer vaccines. The majority of them (89.8%) had an overall good level. Out of all, 92.7% showed a positive overall attitude score toward immunization, 95.4% agreed that community pharmacists can play an important role in advertising and promoting vaccination. The main needed elements for implementing immunization services in pharmacies listed by participants were: support of health authorities (99.3%), statutory allowance (82.8%), patient demand (95.4%), pharmacist's interest (96.1%) and continuous education and training workshops on immunization. Older CPs (50 years and above) [aOR = 0.703, CI 95% (0.598-0.812)] and those working in Bekaa and North have lower knowledge score than their counterparts. High educational level [aOR = 1.891, CI 95% (1.598-2.019)], previous experience in immunization [aOR = 3.123, CI 95% (2.652-4.161)] and working in urban areas [aOR = 3.640, CI 95% (2.544-4.717)] were positively associated with a good knowledge level.

**Conclusion:** Most of Lebanese community pharmacists are willing to offer immunizations. The expansion of the pharmacists practice scope to include provision of immunizations required a national plan that encompasses

**Introduction**

Immunization is considered as one of the most cost-effective strategy for disease prevention [1]. Despite its known benefits, adult immunization rates worldwide fall below desired targets [2]. Many factors have been identified as barriers towards achievement of target immunization coverage rates, including general public apathy, concerns and misconceptions about the safety and efficacy of vaccines, cost, lack of access to immunizers and convenience [3]. Thus, in order to improve immunization rate, there is an urgent need to address these barriers.

Since the focus of healthcare has shifted toward prevention, pharmacists were highly encouraged to expand their practice to incorporate preventive measures including immunization [4, 5]. Besides, one of the suggested strategies to succeed in an immunization program and increase the coverage rates among adults lies in involving pharmacists in vaccine administration [6]. This extension in the practice scope can be achieved through different ways such as starting by advocating immunization through raising awareness about the benefits of vaccine among the public, particularly pharmacy visitors, discussing the patient's immunization status and recommending vaccines during the patient's visit to the pharmacy. Lastly, pharmacists, especially community ones, can be potential immunizers by administering vaccines in their practice setting [7].

In their attempt to increase the rate of immunization, many countries have adopted the strategy of involving non-traditional immunization providers and, thus, allowing pharmacists to administer vaccines [8]. Many studies intended to highlight the positive effects of implementing vaccinations in community pharmacies. The results of these studies showed that pharmacists increase the availability of vaccinations, accelerate immunization, effectively educate patients, affect the vaccination coverage rate, prevent new cases of diseases, and by reducing the number of diseases or complications, they bring savings to the healthcare system [9–13]. Experiences in countries, who adopted the mentioned strategy such as England, Portugal, and the United States, prove the benefits of pharmacy-driven vaccination for both patients and the healthcare system [14]. Similarly, in Canada, following the implementation of vaccination administered by pharmacists, the proportion of people vaccinated in the general population has increased significantly [15].

In Lebanon, the distribution of community pharmacies among Lebanese province is not equitable and its ownership is private on a for-profit basis [16]. According to the Lebanese Order of Pharmacists (OPL) and the Ministry of Public Health (MOPH) laws, pharmacists should be omnipresent during the pharmacy's opening hours. However, they are not permitted by law to administer vaccines. Their role is only restricted to dispense vaccines received from pharmaceutical companies. This year has witnessed a debate about allowing pharmacists to administer influenza vaccine as applied in other countries. Subsequently, MOPH has issued a memorandum No. 149 in October 6th 2020 to assert the restricted role of CPs with regard to vaccine administration. However, based on some observations, it is commonly found that many pharmacists CPs influenza vaccines to their patients as part of their current practices. In addition, it is well known that Lebanese pharmacists are actively involved in raising awareness and public health promotion [17]. In the light of COVID-19 pandemic and the need to enroll a national vaccination plan and prior to embarking on a program expanding the scope of pharmacy practice to include the provision of immunizations, it is important to understand the intention of the Lebanese pharmacist to become an immunization provider. Such information highlights the importance of policy change and legal reform toward expanding the scope of pharmacy practice. Thus, our study aims to assess the knowledge, attitudes and beliefs of community-based Lebanese pharmacists with respect to expanding their scope of practice, in addition to their willingness to participate in vaccine administration.

**Methods**

**Study design and population**

A cross-sectional study using an internet-based survey was conducted during the phase preceding the arrival of the COVID-19 vaccine in Lebanon between 1 and 31st December 2020. Pharmacists were electronically invited to participate. A stratified random sampling method was used in this survey to select a representative sample of CPs from the eight Lebanese provinces. The number of CPs selected from each province was calculated using a probability-proportion to size sampling method based on the list of CPs provided by the OPL. CPs working currently in pharmacy setting and who agreed to participate to the study were eligible for participation. Exclusion
criteria included: clinical pharmacists, retired CPs, those who were out of the country at the time of the survey, as well as those not practicing actually. Pharmacists who were unreachable due to change of their contact information during the time of the survey and those who refused to participate in the study were also excluded.

## Questionnaire development

A 58-item questionnaire was developed and designed specifically by the authors to assess the study objectives and to cover important aspects of pharmacists as immunizers. It was drafted, piloted and modified prior to distribution. A panel of experts involving both rural and urban pharmacists provided comments on the survey design. They were asked to provide qualitative feedback on clarity, wording, interpretability and relevance. Then, the original English draft of the questionnaire was translated and adapted to the Arabic language based on standard translation guidelines [18]. The questionnaire was pre-tested among 30 community pharmacists for survey flow, functionality, readability, comprehension of instructions, and clarity. Based upon feedback from the pre-test, minor modifications regarding readability and clarity were made to the questionnaire. Furthermore, the reliability of the questionnaire was checked. The average time for filling the survey was 12 min. The questionnaire was self-administered and consisted of close-ended questions. It was divided into 6 domains:

1. Baseline information of participants: including age, gender, profile, educational level, clinical experience and working hours in addition to information about the pharmacy (location, opening hours...).

2. Pharmacists' willingness to administer adult vaccines.

3. Pharmacists' knowledge about vaccination.

4. Pharmacists' specific immunization attitudes.

5. Reasons supporting utilizing pharmacists as immunizers.

6. Elements needed to incorporate immunization in pharmacists' practice scope.

Knowledge and attitude scores were computed. Participants' overall knowledge and overall attitude were categorized using modified Bloom's cut-off point as good if the score was equal or more than 60%, and poor if the score was less than 60%.

## Sample size calculation

To calculate the sample size of the study, the Raosoft sample size calculator was used. Based on a total population size of 4185 community pharmacies registered with OPL, a 95% confidence level and an absolute error of

5%, a minimal sample of 352 pharmacists was required to allow adequate power for bivariate and multivariable analyses.

## Data collection

An anonymous online questionnaire using a Google form was sent using WhatsApp or email to all community pharmacists. Then, pharmacists were contacted via phone call and notified about the survey and its purpose. The link of the study included a brief introduction to the background, the objective of the survey, and instructions for filling the questionnaire.

## Ethical considerations

A written informed consent was obtained for each participant. They were reassured that their participation is voluntary and that they are free to withdraw at any time. In addition, all information was gathered anonymously and handled confidentially. The study design assured adequate protection of study participants, and neither included clinical data about patients nor configured itself as a clinical trial. Hence, this study was exempted from ethical approval of the ministry of Public Health.

## Statistical analysis

The collected data were checked for completeness and consistency before analysis. The data were analyzed using the statistical software SPSS (Statistical Package for Social Sciences), version 22.0. A reliability analysis was done to validate each of these scores and was performed using the Cronbach's alpha test. A coefficient of above 0.7 indicated a good internal consistency. Descriptive statistics were reported using frequency and percentages for categorical variables. Finally, the analyzed data were organized and presented in the tabular, graphical and narrative form as necessary.

## Results

### Baseline characteristics of the study participants

Table 1 shows the baseline characteristics of the participants. A total of 412 community pharmacists participated in this survey of which 54.9% are females. Most of them (62.4%) are aged less than 40 years. More than half of them (55.1%) are pharmacy owners and 55.6% have a bachelor of science (BS) in pharmaceutical sciences. With respect to their work, 43.7% of them have a work experience of more than 10 years as community pharmacist and only 23.3% have no previous experience in immunization. Regarding pharmacy distribution, the majority of pharmacists (68%) work in urban area particularly in Mount-Lebanon province (37.6%). Lastly, the majority of pharmacies where our participants work (55.30%) are opened 80-120 h per week.

### Willingness to be an immunizer

Of the total, 66.5% of the surveyed community pharmacists are willing to administer vaccines at this time, if they were legally permitted by the legislation to administer vaccines to adults without additional trainings. The willingness to incorporate this service into their practice rises to 94.4% if the legislation was combined to an

immunization program or certification program (Figs. 1, 2).

### Pharmacists self-reported knowledge

The majority of surveyed pharmacists (89.8%) had an overall good level of knowledge (≥ 60%) and only 10.2% of them had a poor level of knowledge (< 60%). Table 2 illustrates the knowledge domains about vaccination. The majority of respondents were knowledgeable in different domains except the domain related to vaccine contraindications and precautions. The highest knowledge scales were shown in the general knowledge about vaccination (99.3%) and the domain specific to influenza vaccination (90.5%). Besides, around three-quarters of respondents were well informed about the storage, administration and adverse reactions of vaccines.

Table 3 describes pharmacists' answers to vaccination knowledge items. Despite the good level of knowledge recorded in the domain related to the storage and administration of vaccines, only 45.4% of pharmacists were aware that inactivated vaccines may be administered at

the same time or at any time before or after a live vaccine. Similarly, 45.4% of them were not knowledgeable about the fact that local adverse reaction such as pain, swelling, and redness at the injection site generally occurred within few hours of the injection, and are usually mild and self-limited.

In respect of the contraindications and precautions domains of vaccine, only 26% of participants considered that pneumococcal vaccination is not contraindicated for asplenic patients.

### Pharmacists' specific immunization attitudes

Out of all, 92.7% of surveyed pharmacists showed a positive overall attitude score toward immunization. Around 90% of them considered that vaccines produce more health benefits than health risks, and that increasing the proportion of adults who receive recommended immunizations is important. However, only 20.4% of them considered that natural infection or a healthy lifestyle are effective alternatives to vaccines.

### Reasons supporting utilizing pharmacists as immunizers

The majority of respondents (95.4%) agreed that community pharmacists can play an important role in advertising and promoting vaccination. Moreover, more than 90% of them considered that allowing pharmacists to vaccinate can reduce costs paid by patients, and that pharmacies are easily accessible to the community which will improve the overall vaccination rate among adults as they feel more comfortable. In addition, 84.7% of them agreed that pharmacists should be legally permitted to administer vaccines. However, only 50% of respondents agreed that pharmacists have received adequate teaching/training about vaccine administration during their education (Fig. 3).

### Elements needed for implementing immunization services in pharmacies

The main needed elements for implementing immunization services in pharmacies listed by participants were:

support of health authorities (Ministry of Public Health and Order of Lebanese Pharmacists) (99.3%), statutory allowance (82.8%), patient demand (95.4%), pharmacist's interest (96.1%) and continuous education and training workshops on immunization, safe administration and handling of vaccines (93.7%). Only 55.6% of participated pharmacists highlighted the need of formal certification in vaccine administration as requisite for allowing pharmacists to be immunizers (Table 4).

### Factors associated with good knowledge among CPs

Table 5 displays the factors associated with good knowledge score among CPs. Older CPs aged 50 years and above [aOR=0.703, 95% CI (0.598–0.812)] were less knowledgeable than younger CPs aged between 20 and 39 years old. CPs with higher education level than BS in pharmaceutical sciences [aOR=1.891, CI 95% (1.598–2.019)] and previous experience in immunization [aOR=3.123, CI 95% (2.652–4.161)] were more likely to have a good knowledge score than those who have a BS degree in pharmaceutical sciences and who lack from previous experience in immunization. CPs working in pharmacies located in urban areas [aOR=3.640, CI 95% (2.544–4.717)] showed better level of knowledge than their counterparts working in rural areas. Our findings showed also that CPs working in Great Bekaa [aOR=0.703, CI 95% (0.598–0.812)] and great North have lower odds of good knowledge than those working in Beirut.

### Discussion

This study was conducted during the preparedness phase for the roll-out of COVID-19 vaccines in Lebanon. It has particular importance during the COVID-19 pandemic as pharmacists could have a responsibility to take a prominent role in combating infectious diseases and control programs in health-care systems, in addition to their significant impact on the vaccination coverage rate. To the best of our knowledge, this is the first representative national Lebanese study aiming to explore readiness and

willingness of community pharmacists to expand their practice scope into administering vaccines for adults.

The main findings in our study were that more than half of the surveyed community pharmacists are willing to start in the meantime the administration of vaccines in case they were legally permitted to do it without additional training. However, this willingness to incorporate this service into their practice rises to more than 90% if the legislation was combined to an education or

certification program. This could be explained by the fact that despite their willingness to proceed, many pharmacists felt not well prepared, given that their education was not sufficient to begin at this time incorporating immunization services at their practice, and that formal certification should be required to do so. In this context, many pharmacist regulatory bodies have recognized the stipulation of proper immunization training prior to service provision, hence, the need of

developing immunization training programs to ensure safe and effective administration of vaccines by pharmacists [19]. Such programs show their success in the Maritimes, in which 97% of pharmacists felt prepared to administer immunizations following completion [2].

In regard to community pharmacists' knowledge, our results showed that the majority of respondents were knowledgeable in different domains except the domain related to vaccine contraindications and precautions. Good knowledge is crucial to expand the scope of
practice of pharmacists as it supports them in providing adequate education to the public and, consequently, improving their performance and confidence in administering vaccines. However, this study indicates that respondents lack the necessary knowledge of precautions and contraindications of vaccines, and those related to its administration such as the possibility of administration of inactivated vaccines at the same time or at any time before or after a live vaccine. Also, knowledge regarding the fact that local adverse reaction occurring at the injection site within few hours of administration and that are usually mild and self-limited, was not well recognized. These gaps in knowledge may need to be narrowed and underline a crucial need for strategies to educate community pharmacists about particular aspects of the contraindications and precautions of vaccines through continuing medical education, supplementary professional information, and additional patient educational materials [20]. It should be noted that a good proportion of the participants recognized the need for further education in this field.

It is notable that our results proved positive attitude toward utilization of pharmacists as immunizers. Most of pharmacists appraised the importance of their role in advertising and promoting vaccination among public. This is consistent with the findings of a study conducted in Italy that investigated KAP regarding vaccinations by community pharmacists in Italy [21]. Moreover, pharmacists believed that allowing them to vaccinate can reduce costs paid by patients and that pharmacies are easily accessible to the community which will improve the overall vaccination rate among adults as they feel more comfortable. Our results aligned with the findings of many studies that showed that vaccination costs were less when this service was provided by pharmacists, compared to those that were physician-administered [22]. Another study showed that immunization rates against influenza were higher for individuals aged more than years old in areas where pharmacists provided vaccinations, most likely due to improved accessibility and convenience [23, 24]. Finally, increased vaccination rate will be translated by a decrease in mortality and hospitalizations rates in elderly patients; hence, reduction of the cost related to direct medical care [25, 26].

In addition, 84.7% of pharmacists agreed that they should be legally permitted to administer vaccines. This highlights the importance to focus on statutory reform to enable pharmacists to provide vaccination under the umbrella of law [27].

Since only half of respondents agreed that pharmacists have received adequate teaching/training about vaccine administration during their education, additional training for proper immunization practices is

highly recommended. This should be synchronized with regulation changes anticipated by the profession and pharmacy schools to expand the scope of practice and enable pharmacist-administered vaccination.

Regarding the factors necessary for the implementation of vaccination services in community pharmacies, participants indicated that support of health authorities (Ministry of Public Health and Order of Lebanese Pharmacists), statutory allowance, patient demand, pharmacist interest and continuous education and training workshops on immunization, safe administration and handling of vaccines are needed. Consistently, many studies found similar results with respect to essential elements identified, such as legal liability and formal education [28, 29]. With respect to patient demand, CDC estimates that almost 20% of the 2010–2011 influenza adult vaccinations were administered by pharmacists [30].

In terms of factors associated with CPs' good knowledge, our findings showed that CPs with older age, and working in pharmacies in Bekaa and North have lower knowledge score than their counterparts. However, CPs with high educational level, previous experience in immunization and working in urban areas showed higher tendency to have good knowledge level. Our results were comparable to the findings of a study conducted in Italy that revealed that higher level of knowledge was reported among younger CPs and those with a lower number of years since degree [21]. The role of higher education in predicting better vaccination knowledge might be due that they have more opportunities to learn and receive adequate education and training through their university pharmacy curricula. Given that CPs can be a key point of contact for patients especially who live in rural areas, our findings highlighted the importance of improving the knowledge of the CPs who worked in such areas.

Continuous education and training workshops on immunization, safe administration and handling of vaccines are recommended in addition to the formal certification in vaccine administration as requisite for allowing pharmacists to be immunizers. Vaccine adverse event reporting systems are essential to ensure vaccine safety and surveillance, and maintain people's confidence in vaccines. There is need to establish immunization records which allow pharmacists to identify missed vaccinations, offer reminders to patients, and update immunization records to improve reporting of immunization coverage. Further integration of such systems and procedures across healthcare providers are needed for pharmacists to be incorporated in the overall health system to present a united front in offering vaccination services. Lastly, it is necessary to prepare standards as well as a legal framework for the provision of such services.
## Limitations of the study

Some limitations of this study should be acknowledged. First, the cross-sectional design of this study does not allow us to infer causality. Second, our study relies on community pharmacists' self-reported information, which makes it prone to the disadvantages of desirability biases. Furthermore, this online questionnaire might have favored a selection bias since it might only allow the participation of community pharmacists who have access to online resources. Lastly, recall bias could have occurred particularly for the questions related to past behavior.

## Conclusion

Most of Lebanese community pharmacists are willing to offer immunizations. Thus, the expansion of CPs scope of practice to include the provision of vaccine required the implementation of a national plan. This plan can encompass the following pillars that should be incorporated in parallel: strengthening knowledge and education about the topic for graduated pharmacist, incorporating vaccines and immunization in the academic curricula, offering post-graduate certificate and diploma for eligibility to administer vaccines with periodic re-certification, enhancing the role of pharmacovigilance and reporting within this scope and, statutory reform. Future studies are needed to examine pharmacists' perceived barriers about immunization, as well as the determinants of their willingness to administer vaccines.
