INTRODUCTION: The current global coronavirus (Covid-19) pandemic has once again highlighted the need to enhance the role of community pharmacists in public health. In 2012, the World Health Organisation (WHO) estimated that global deaths due to non-communicable diseases (NCDs) as about 38 million (68%). Most of these conditions are preventable through public health initiatives involving community pharmacists. This study aims to explore strategies enhancing the public health role of community pharmacists. METHODS: Data was collected through telephone interviews, supported by Skype (audio), and recorded using the 'HD Call Recorder for Skype'. The qualitative data software package NVivo (version 10) was used for the storage, retrieval and analysis of data. The constant comparative method of data analysis was used. In addition, the Theoretical Domains Framework (TDF) was used to underpin the research throughout. RESULTS: This study identified a number of strategies that could enhance the public health role of community pharmacists, some of which include: integrating undergraduate healthcare programmes; broadening the public health knowledge of students and pharmacists; pharmacists working alongside other healthcare professionals; teaching communication methods to students and pharmacists; teaching the use of new technologies and social media; etc. In addition, most of the 14 domains of TDF and several of their constructs were captured in the interview. CONCLUSIONS: To enhance the public health role of community pharmacists, it is necessary to develop pharmacists’ capacity in several areas, particularly as it relates to, the use new technologies and social media in public health; enhancing training of pharmacists/students in public health; empowering pharmacists in public health; as well as teaching communication methods to students and pharmacists. Part of the strategy will also be, to integrate healthcare programmes through interdisciplinary initiatives, and changing the undergraduate pharmacy curriculum to increase its public health content.

The current global coronavirus (COVID-19) pandemic has once again highlighted the need to enhance the role of community pharmacists in public health. 1 As of 14 th July 2020, the global situation in numbers of coronavirus was put at 12, 768, 307 cases (566 654 deaths), with the rate of infection increasing daily at an alarming rate in many parts of the world. 2 With regards to non-communicable diseases, in 2012, the World Health Organisation (WHO) estimated that global deaths due to non-communicable diseases (NCDs) was about 38 million (68%). 3 However, most of these conditions are preventable through public health initiatives involving community pharmacists.

In terms of contemporary policy context in the world of pharmacy it has been argued that pharmacy education and practice have changed from their initial narrow product-centred focus to the present patient-centred focus in many countries globally, although to different degrees. 4 According to the Royal College of Nursing, patient-centred (or person-centred) care is about focusing care on the needs of the person rather than the needs of the service. 5 In other words, the person or patient is seen an equal partner in the planning of care, and his or her opinions are important and are respected. 5 However, there is now a demand from healthcare professions and various governments for a public health-oriented healthcare education and practice that prepares the present healthcare practitioner (including pharmacists) to see beyond the individual patient to his community and society. 4 This is important as this can help enhance the quality of patient care (including patient safety), improve the patient experience, as well as reduce costs of health care. 6 A similar change in pharmacy education and practice have also been made, 7 such that, will necessitate pharmacy education to comprise the right public health orientation to prepare and empower pharmacists with the necessary knowledge, skills, attitudes, and values crucial for contributing to public health, both at the micro and macro levels, regardless of their practice setting. 4 Micro-level public health functions have been defined to include those activities provided by pharmacists such as, disease management, health and wellness screening, immunisations, medication therapy management etc., while macro-level public health functions include examples such as, assessment, policy development, and assurance at the population-based level. 8 Added to the increasing expectation for pharmacists to be knowledgeable in both pharmacy and population-based healthcare, is also the need for future pharmacists to understand the wider concept of public health, with the objective of improving health at a population level. 9, 10 Still, in a UK service-focused study, 11 it was identified that community pharmacists around the globe were providing a wide range of roles in public health. They included: smoking cessation services; infection control and prevention; promoting cardiovascular health and blood pressure control; provision of emergency hormonal contraception (EHC); prevention and management of drug abuse, misuse and addiction; and healthy eating and lifestyle advice. This study contributed to the decisions of an important UK public health paper, 12 with its findings further confirmed in a later study. 13 More so, it has been recognised that community pharmacists are in a prime position to help combat health issues, many of which are identified risk factors for chronic diseases. 14 This is important, as community pharmacies are easily accessible and provide a convenient and less formal environment for those who cannot or do not wish to visit other kinds of health services. 14, 15 Still, in a study conducted in the UK, it was identified that despite the sharp increase in the number of pharmacy schools, this has not had much impact on the teaching of public health to students, particularly as public health remains an optional module in many UK schools of pharmacy. 16 . In some schools, public health was integrated into other modules; in general, the curricula of most pharmacy schools were often dominated by traditional modules designed to enhance students' knowledge and skills in the sciences, dispensing, production, research, law and ethics, and clinical pharmacy. 16 This however contrasted with the evidence from many developed nations, that indicated that many pharmacy schools have incorporated public health as one of the core subjects taught in their undergraduate curriculum. 17, 18 Nevertheless, pharmacists will be expected by healthcare providers and funders to evaluate public health policies for costs and effectiveness as well as collaborate with government agencies in formulating public health policies. 19 On the effectiveness of community pharmacists in public health, the literature suggests that the essential public health service where pharmacy presence is most felt is in evaluating the effectiveness, accessibility, and the quality of personal and population-based health services. 20 Next is to link people to needed personal health services and assure the provision of health care when otherwise unavailable. 20

Aim: To explore strategies enhancing the public health (including the medication management, surveillance, referral, and follow-up) role of community pharmacists.

Design This is a qualitative study involving the use of in-depth semistructured telephone interviews with community pharmacists and other healthcare professionals. The sample size for the study was determined during the process; hence, the interviews were continued until no new information was yielded or data became saturated. 21, 22 A convenient sample of participants were selected, based on their availability and willingness to participate in the study. Informed consent was obtained from participants prior to inclusion in the study. Data was collected through telephone interviews, supported by Skype (audio); using an interview guide that incorporated open-ended questions. 23 Interviews were recorded with HD Call Recorder for Skype, and lasted approximately 20-30 minutes. These interviews were facilitated by the three members of the research team (CA, JO, and JP). CA conducted the in-depth semistructured interviews, consistent with the method suggested for such interviews. 24 Researchers JO and JP reviewed the potential topics to determine their suitability. 25 Participants were assured that confidentiality was guaranteed. 26 This meant explaining to the participants exactly what was meant by anonymity and confidentiality, 26, 27 and ensuring that informants were not identified by quotes from the data, hence, the use of initials to identify participants in the results. 28

The qualitative data software package NVivo (version 10) was used for the storage, retrieval and analysis of data. CA transcribed the interviews verbatim. Experienced researchers (JO & JP) independently verified the coding procedure, as part of the validity check on the interpretative process. In the analysis, thematic analysis was used. 29, 30 Essentially, the phases include familiarising yourself with your data; generating initial codes; searching for themes; reviewing themes; defining and naming themes and producing the reports. 29 For this analysis, sentences were used as the units of analysis. Initial codes were assigned to data that was of interest to the analytical framework through process of repeated reading, the emphasis being on including all relevant data. In some cases, multiple codes were assigned to each unit of analysis. As the analysis progressed, the number of new codes created diminished, indicating the point of saturation -which is the point of when no new information is yielded. 21 The next step was a process of code refinement where codes were considered together to identify patterns and connections to form what became subcategories, which were then connected across higher order categories. 31 Emerging themes were reviewed for counterthemes (themes that oppose another themes). 32 In addition, some numerical data were presented in the analysis. 33 The Theoretical Domains Framework (TDF) was used to underpin the research throughout (see Table 1 ). The TDF is an integrative framework, which is as a vehicle to help apply theoretical approaches to interventions aimed at behavioural change. 34, 35 This is particularly important as enhancing the role of community pharmacists in public health can help pharmacists use behavioural change tools to improve healthcare and health outcomes. 34 Such behaviours may be those of healthcare workers, for example, implementation of evidence-based practice of patients, medication adherence of the general population, or even smoking cessation and increasing physical activity. 34 Moreover, as some of the anticipated strategies might also involve changing pharmacists' attitudes and behaviours towards the public health role, one would therefore anticipate that a greater appreciation and application of these behavioural change models by pharmacists, their trainers and possibly employers, will lead to better outcomes in public health

To enable implementation of health care interventions, the TDF can be used prospectively 36 as well as retrospectively in theory-based process evaluation. 34 Hence, the TDF brings together the models and theories of behavioural change. 37 According to Jones, et al., the TDF was originally comprised of 12 domains, however, this was later increased to 14 domains -each domain obtained from the constructs of many behavioural change theories. 37 A domain is defined as comprising, a set of similar theoretical constructs (see Table  1 ). 38 

In terms of characteristics, fifteen healthcare professionals (including ten pharmacists, one pre-registration pharmacist, three general practitioners and a nurse) were included in the interviews. Nine (60%) of the healthcare professionals interviewed were female, while majority of participants (seven) [46. 7%] aged 50 to 59 years. Following the interview with the healthcare professionals, a number of themes emerged from the data analysis.

According to the WHO, activities that enhance public health capacities and services provide conditions that enable individuals to continue to be healthy, improve their wellbeing, or prevent the worsening of their health. 39 Participants suggested a number of strategies needed to enhance the public health role of community pharmacists. "…we see a lot of patients with minor illnesses that come to the GP and I think this is a waste of time…You see them, especially in the winter months… patients can be educated more…like give them a list of conditions that, 'these things, you don't really need to see your GP…crowding the A&E, go to your pharmacist'. Your pharmacist obviously is the one that will say, that thing is beyond me, and you go and see your GP. But, I think also, maybe providing…triage services"

Empowering pharmacists in public health activities Still, the wider issue of empowerment by the public, the commissioning and regulatory bodies [beliefs about capabilities] was also highlighted by two pharmacists who felt that not much can be achieved without the support of these very important groups.

"So, whoever is acting in the capacity of the function for today, is taking responsibility for every aspect of public health,...and they should be remunerated accordingly and not the business…So, there are many, many roles pharmacists can do, if value is place on them to do it, if they're remunerated accordingly..." [P-OL] Integrating healthcare programmes On the integration of healthcare programmes, there is now an emphasis on interdisciplinary initiatives in the management of many causes of ill health. 45 In terms of inter-professional education, it is driven mainly by health professional education associations. 46 Based on the responses most participants would like interdisciplinary initiatives between health professions to be a way forward. 

Although, one of the pharmacist participants was aware of some of the advantages associated with integrated learning, for example, the ability to develop collaborative practices with other health professionals, however, she was also concerned about the logistics associated with this arrangement [material resources (availability and management), and social influences -crew resource management]. Her main concern being that often these other schools (e.g. medicine and nursing) tended to have large classes, which could then be difficult to manage across schools. There is also the issue of breaks and calendars, which she argued, were not always aligned between schools and faculties.

Another concern from another pharmacist [P-NKT] was that integrated learning could also lead to the dominance and the prioritisation of other healthcare students during lectures [professional role and identity], which could then put pharmacy students in a difficult situation [emotion -anticipated regret, fear and threat]. Although, another participant recognised the need for integration, he was however concerned that unlike in the hospital were such interactions seemed natural, particularly during ward rounds; in the community setup this type of integration might be difficult with GPs [social influences: conflict -competing demands, conflicting roles].

On changing the curriculum, some earlier studies have identified the need to enhance the public health content of pharmacy curriculum. 11, 48 Enhancing public health knowledge and skills According to the pre-registration pharmacist participant, as many of the common chronic conditions are linked with lifestyles [memory, attention and decision processes -decision making], it was important to enhance both the public health knowledge and the collaborative skills of healthcare professionals [knowledge and skills]. This will therefore mean spending money [environmental context and resources] on the public health education of health professionals, as a preventative measure, rather than on certain therapeutic medicines.

"…every healthcare professional want to do public health…but, these ailments are linked together. We're looking at diet and we're looking at smoking, smoking is linked to COPD or emphysema, as we used to know it in the day and chronic bronchitis and things like that. If we look at the lifestyle, exercise and the food we eat, that goes on into diabetes…And how many people are overweight? And that's leading into those with heart conditions...I will rather, instead of asking the money on simvastatin and things like that, can we not just train our healthcare professionals… from Day 1. "People need to know, because when they qualify they can't escape new technologies" (P-SOL).

This need to embrace the use of new technologies was also supported by many other participants, who argued that there was no way the pharmacy profession could move forward [intentions], without pharmacists embracing modern technologies:

"Obviously, as we advance it seems like the computer is here to stay and the robot is here to stay. So, definitely, it needs to be on the curriculum." [GP-NA]

In terms of specifics, some of the new technologies recommended included, the "development of diagnostic tools" (P-PO), the use of the "EPS 2 system" (P-VIV), "telephone systems", social media tools such as the "Smart Messaging Service (SMS)", "Twitter" and "Facebook" (P-JO), with one participant suggesting the use of "robots" (N-ART). Strangely, there was nothing to suggest from the interviews that participants themselves were making use of these tools in their practices.

"…Technology in diagnosis is important, because if you look at the minor ailment scheme, which we do, it is more or less guesswork. So, a technology…that tells you that look, this is a bacterial sore throat and so should be referred to the doctor, or that is this cough, is reflective of cancer that should be referred or that…the cough is probably due to dust inhalation or something like that. Yes." [P-PO]

As well as these, pharmacists involvement in public health was also linked to increasing prescription only medicines (POM) to pharmacy medicines (P) switches. However, for one of the participants, this was not just about treatment, it was also about preventing long-term diseases, which could then save lives through lifestyle changes, etc. [beliefs about capabilities]. Again, this benefit was not for doctors alone, but also for other healthcare professionals and the entire health system [social influences -team working and organisational development]. Nonetheless, to enable community pharmacists achieve these public health aims, one pharmacist participant argued also that it was imperative to enhance the undergraduate pharmacy curriculum, so as to enable pharmacists to identify disease patterns easily, even at a global level [skills] . "…You could be part of the global team necessary to enhance global health." (P-JO).

Through this project, it has been possible to explore some of the strategies needed to enhance the public health role of community pharmacists (incorporating TDF as a framework for analysis). Regarding the adoption of new technologies and social media in practice, it has been argued that social networks can be great tools to obtain professional knowledge, as well as disseminate information globally. 51 Moreover, platforms such as Twitter can offer real-time access to news while allowing people to leave their opinions. 51 On the other hand, LinkedIn could be used to build a professional profile and get in contact with other professionals. 51 Despite these benefits, it has also been argued that the number of pharmacists using social media in practice is minimal, raising the possibility that pharmacy practice in general is not taking up the opportunity offered by social media. 51 With the increasing popularity of apps, with estimates in 2014 put at 138 billion downloads worldwide, there are signs that UK pharmacists are slowly catching up with these new technologies in practice. 52 In community pharmacy, a number of pharmacists are now using apps designed to calculate an individual's chance of developing cardiovascular (CV) disease in the next ten years by recording information on height, weight, smoking history and family heart history; a Diabetes UK risk score app for calculating an individual's risk of developing type 2 diabetes; a Diabetes UK app for type 1 or type 2 diabetes daily blood glucose monitoring; an app for electrocardiograph (ECG) reading within 30 seconds; an app designed as a game to test a person's memory function, and another app which reminds patients when to take their medicine and prompts them if they forget. In addition, there is now a wellbeing app for psychological support for all NHS staff, including those working in primary care, during the COVID-19 outbreak. 53 Nonetheless, it appears sound to also put into consideration the emotional impact [fear as well as threat] which the use of new technologies and social media could have on pharmacists, particularly with regards to their job security (P-PO). Having said that, it seems also reasonable to argue that UK pharmacy schools should likewise reflect the teaching of these new ways of delivering public health services strongly in their curricula. This need becomes even more important during this current coronavirus pandemic. While most of the interview participants were in support of the use of new technologies and social media in practice, a few of them, particularly the older ones, were less supportive of their use in practice. Some of their concerns centred around privacy, which is also an environmental constraint, and confidentiality -possibly due to lack of beliefs about capabilities of pharmacists and their staff.

Still, it has been noted that in practice, that little attempt is made by healthcare professionals to assess patients' understanding of any health advice given. 54 56, 57 revealed that enhancing the public health role of community pharmacists can significantly reduce the cost of treatment as well as the workload of other healthcare professionals, by reducing GP and A&E appointments for minor conditions that can easily be managed by pharmacists.

A UK pharmacy association supports this initiative, which they believe will help enhance both the clinical and the public health roles of community pharmacists. 58 While it might appear realistic that GPs should transfer some of their minor clinical and public health roles to pharmacists, so as to enable them to focus on more complicated clinical and public health cases, this is not always an easy transition. The reason is that while it is a lot easier for GPs to take on some of the specialist doctors' roles due to the uniformity of undergraduate training, this is not the case with pharmacists, whose undergraduate training has been developed traditionally as a science rather than a clinical/public health programme. In many UK pharmacy schools, it has been noted that public health is often taught to students as an optional module or integrated with other topics. 16 There is now a need for public health to be presented as a core module in the curricula of UK Schools of Pharmacy, so as to broaden and advance the knowledge base and skill set of pharmacists in public health. There is also a need for Schools of Pharmacy to further develop their curricula, particularly as it relates to the use of motivational tools, for example, the Transtheoretical One of the concerns raised by one of the participants [P-ART] was the problem of logistics when it comes to integrating undergraduate pharmacy education with other healthcare professions [environmental context and resources]. While integrated learning might be a challenge for stand-alone Schools of Pharmacy without a nearby medical, dental or nursing school; yet, it is possible for these schools to liaise with nearby health facilities, for example GP practices, local health centres and hospitals, as a way forward. Again, exchange training programmes and internships with other schools and health institutions could also be helpful, as well as the use of online technologies, for example Skype, Zoom or other conferencing software, to enhance communication skills, manage logistics, build rapport and understanding among professions, as well as facilitate integrated learning and exchange of ideas.

Nevertheless, remunerating pharmacists directly for providing public health services can help enhance their role in public health, 65 as against the present system, where only pharmacists' employers are remunerated for public health services provided by pharmacists. Supporting this initiative, one of the interview participants [P-OL] had argued that, 'they (pharmacists) should be remunerated accordingly and not the business'. One benefit of this model is that it limits some of the constraints often associated with employer-led public health services, such as the use of targets and financial considerations. 66 To address some of these challenges, the profession might also need to consider promoting the establishment of Healthy Living Pharmacies [skills] . 67 In order to support this role, community pharmacists might need to reach out to the community, and running public health programmes in libraries or other community meeting places, at the same time, developing their own expertise in public health. A good example of this reach out could be, pharmacists/pharmacy engaging in employee health fairs -defined as, services provided to employees at local businesses, including cholesterol screenings, blood pressure screenings, [coronavirus screening], and height, weight, and body mass index measurement; (with) written results given to patients. 68 Regarding recommendation for further studies, these findings could be made more illuminating by exploring the perspectives of healthcare users. Further researcher on the need for a dual pharmacy degrees and the use of new technologies and social media might be needed to explore how these could help enhance the public health role of community pharmacists.

The TDF and several of its constructs 38 were very useful in analysing this data. However, some of the limitations of the study included, difficulty associated with analysing interviews, which is very time-consuming. Moreover, the pre-knowledge of some of the respondents may also have affected both the issues raised 69 and the respondents' willingness to share certain views. 70 The study findings could have been enhanced by including a wider range of healthcare practitioners, for example, hospital consultants, specialist public health practitioners/consultants, dieticians, even the public, etc.

This study identified a range of strategies that could potentially enhance the public health role of community pharmacists in the UK, particularly as it relates to the use new technologies and social media in public health; enhancing training of pharmacists/students in public health; creating awareness about public health activities; empowering pharmacists; developing independent pharmacist practitioners; as well as teaching communication methods to students and pharmacists. Part of the strategy will also be, to integrate healthcare programmes through interdisciplinary initiatives, and changing the undergraduate pharmacy curriculum to increase its public health content. Interestingly, most of the 14 domains of the TDF and several of their constructs 38 were captured in the interviews. Applying these constructs to the identified strategies, it seems necessary to develop pharmacists' capacity in several areas, particularly as it relates to: knowledge, skills, social/professional role and identity of pharmacists; enhancing optimism, beliefs about capabilities and beliefs about consequences, as well as streamlining intentions and goals within the profession. Yet, it might also be necessary to manage social influences (norms) and the emotion of pharmacists, enhancing reinforcement (particularly as it relates to rewards and incentives), as well as the environmental context and resources available to community pharmacists.
