Abstract

Community pharmacists are one of the most accessible healthcare professionals and are often served as the first point of contact when it comes to minor ailments and health advice. As such, community pharmacists can play a vital role in a country's response to various preventative and public health measures amid the COVID-19 pandemic. Given the essential nature of community pharmacy as a health service, community pharmacies are unlikely to shut down in any foreseeable lockdown scenario. It is therefore important to assess the preventative measure directives for community pharmacies that are in place to safeguard community pharmacy personnel from SARS-CoV-2 in the various parts of the world. Upon reviewing the recommendations of 15 selected countries across five continents (Asia, Europe, Oceania, North America, and Africa) on social distancing and the use of personal protective equipment (PPE) in community pharmacies, we found inconsistencies in the recommended social distance to be practiced within the community pharmacies. There were also varying recommendations on the use of PPE by the pharmacy personnel. Despite the differences in the recommendations, maintaining recommended social distance and the wearing of appropriate PPE is of utmost importance for healthcare workers, including community pharmacy personnel dealing with day-to-day patient care activities, though full PPE should be worn when dealing with suspected COVID-19 patients.

Introduction

The novel coronavirus disease 2019 (COVID-19) is the biggest immediate public health challenge facing our world currently. At the time of writing, nearly 3 million people have a documented positive test for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and over 150,000 have lost their lives. Community pharmacists are one of the most accessible healthcare professionals and are often served as the first point of contact when it comes to minor ailments and health advice. As such, community pharmacists can play a vital role in a country's response to various preventative and public health measures. At the same time, community pharmacy personnel should practice general precautions and put in place the necessary preventative measures to ensure their wellbeing and safety.

Given the essential nature of community pharmacy as a health service, community pharmacies are unlikely to shut down in any foreseeable lockdown scenario. As community pharmacies are considered as the first point of call for cold and flu symptoms, community pharmacy personnel are likely to encounter symptomatic or asymptomatic (including carer of a symptomatic patient) carrier of SARS-CoV-2 and thus at high risk to get infected. Since infected individuals may not show symptoms at least during the incubation period, there is an increasing probability of further transmission of SARS-CoV2 to the general public visiting pharmacies. Therefore, social distancing and the proper use of personal protective equipment (PPE) are essential in community pharmacy practices.

The front-line role of community pharmacies/pharmacists is likely to expand further in the coming days as the COVID-19 situation worsens. For example, the New York state government is planning to allow independent pharmacists (more than 5000 pharmacies) to conduct diagnostic COVID-19 tests. It is therefore important to assess the preventative measure directives for community pharmacies in terms of social distancing rule and use of PPE that are in place to safeguard community pharmacy personnel from COVID-19 in the various parts of the world. These measures will not only provide reassurance to community pharmacy personnel to carry out their professional duties optimally to serve the local communities but will also provide useful information for countries that are yet to issue preventative measure directives for the operation of community pharmacies amid COVID-19 pandemic.

Recommendations on social distancing and the use of PPE

We reviewed the recommendations of 15 selected countries across five continents (Asia, Europe, Oceania, North America, and Africa) on social distancing and the use of PPE in community pharmacies. The recommendations are tabulated in Table 1 . There were inconsistencies in the recommended social distance to be practiced within the community pharmacies, a range from at least 1 m to at least 2 m. More than half (n = 9) of the countries adopted a social distance of 1 m in their community pharmacies. United Kingdom, New Zealand, and Canada recommended a social distance of 2 m, while Australia and the United States advised social distances of 1.5 m and 1.8 m, respectively.

There were also varying recommendations on the use of PPE by the pharmacy personnel (Table 1). While the United States adopted a universal mask approach and Turkey recommended the use of masks and protective goggles for their pharmacy personnel, almost all of the countries recommended against routine use of face mask and other PPE (gloves or aprons/gowns), except when dealing with suspected COVID-19 patients or performing activities requiring close contact (unable to maintain recommended social distance) with the patients. Canada left the decision on the use of PPE during close contact activities to the professional judgment of pharmacy personnel.

Does evidence support these recommendations?

Since WHO's recommendation is to keep a distance of 1 m from others, it is not surprising that most countries adopted the same social distance in the community pharmacy setting. The purpose of social distancing is to avoid contact with respiratory droplets. The one-meter recommendation probably originates with work done in the 1930s by William Wells, who found that respiratory droplets tend to land within three feet when expelled.1 Nevertheless, a distance of 1 m may not be enough, since a 2003 study on the transmission of severe acute respiratory syndrome reported that 90% of the individuals who became infected were seated more than 1 m away from the index patient.2 Such finding suggested that viruses may spread as an airborne aerosol and challenges the traditional belief where the virus is transmitted only through droplets that are coughed or sneezed out.

The evidence from preliminary studies and field reports have indicated the possibility for SARS-CoV-2 to spread in aerosols. To exemplify, during the peak of the COVID-19 outbreak in Wuhan, China in February and March 2020, researchers at Wuhan University set up aerosol traps in and around two government-designated COVID-19 hospitals which were exclusively used for the treatment of COVID-19 patients during the outbreak and public areas in Wuhan including busy department stores. The existence of SARS-CoV-2 in aerosol samples was determined through the quantification of ribonucleic acid (RNA) genetic material.3 They reported the finding of viral RNA from SARS-CoV-2 in various places of the hospitals as well as the entrance of a department store with customers frequently passing through. Recently, a new study in China observed that the SARS-CoV-2 coronavirus-laden aerosols could be found in air samples as far as 4 m away from infected patients.4 These findings are consistent with a recent experimental work that demonstrated the existence of a multiphase turbulent gas cloud and its payload of pathogen-bearing droplets from sneezes and coughs, which could travel up to 8 m.5

Whilst questions remain regarding the infectivity of these airborne virus-laden aerosols, a preprint illustrated the possibility of SARS-CoV-2 coronavirus-laden aerosols to be infectious where the authors investigated an outbreak of COVID-19 involving three non-associated families sitting at three neighbouring tables in a restaurant in Guangzhou, China.6 Ten individuals from these families were found to be infected although no significant close contact or fomite contact was observed. Though the observation from such case study cannot be regarded as conclusive, the assumption, for now, should be that airborne transmission of SARS-CoV-2 is possible unless being discredited in the future, and therefore we opine that the wearing of appropriate PPE is of utmost importance for healthcare workers, including community pharmacy personnel dealing with individuals may or may not be infected on a day-to-day basis, regardless if they manage to observe social distancing in their workplace or if they perform close contact activities. People can spread the virus before they develop symptoms, which limits the detection of suspected individuals through symptoms screening. The need for appropriate PPE cannot be overstated in community pharmacies which are frequently visited by individuals with ailments and are unable to observe social distancing at ALL times due to constraint in the floor space of pharmacies. Indeed, a snapshot survey among pharmacists in the United Kingdom indicated that 94% of respondents were unable to maintain social distancing from other pharmacy personnel, while another 40% of respondents were unable to maintain social distancing from patients.7 Another rather worrying finding, 34% of respondents said they are unable to source continuous supplies of PPE. There are concerns from some countries (e.g. Ireland) if routine use of PPE may compromise other appropriate hygienic measures, but we would optimistically assume that such concern should be least expected among community pharmacy personnel with their healthcare knowledge and professional peer pressure.

A case study from Singapore underlines the importance of appropriate PPE where it was reported that healthcare workers (85% wearing a surgical mask and 15% wearing an N95 mask) identified to have had exposure for ≥10 min at a distance of <2 m from patients with SARS-CoV-2 undergoing aerosol-generating procedures, none became SARS-CoV-2 positive by nasopharyngeal swab within 14 days of exposure.8 Therefore, a universal PPE approach adopted by the United States and Turkey should be complimented and strongly considered by other countries. Relevant health authorities when issuing the preventative measure directives for community pharmacies may consider the availability of local resources due to a worldwide shortage of PPE, but we feel that recommendations should be made based on current science and not based solely on the supply of PPE. A similar analogy would be the issuance of evidence-based recommendations in clinical practice guidelines regardless of the supply of medications. However, in cases where a continuous supply of PPE to community pharmacies cannot be confidently maintained, consideration should be given to recommending a further social distance specific to community pharmacy settings to avoid the transmission of SARS-CoV-2 viruses in infectious amount. Else, innovations such as the installation of the Perspex or plexiglass barrier at the customer contact area to provide barrier protection could also be promoted if feasible. Community pharmacy could unwittingly become a hub for COVID-19 transmission without strict preventative measures in place because is often being the first point of contact for people who are sick and being the place for patients with non-communicable diseases including hypertension and diabetes who are at high risk of being infected with COVID-19 to get their routine medicine supply.

Conclusion

Though a difference among countries with regards to recommended social distance in community pharmacy, it must be stressed that the recommended distance is the minimum distance that should be followed, and measures should be taken to increase the social distance as far as possible to avoid transmission of SARS-CoV-2. However, the currently recommended social distance might need to be updated in accordance with current findings with SARS-CoV-2. Also, considering the potential for SARS-CoV-2 to aerosolize, pharmacy personnel should be protected at least with medical-grade face mask, along with other PPE if necessary, to deal with day-to-day patient care activities, though full PPE should be worn when dealing with suspected COVID-19 patients. Therefore, the distribution of local PPE resources should take into consideration the need for community pharmacy personnel, who may be neglected due to false assumptions for low risk of transmission. The last thing we may want to see is for community pharmacies to become a source of transmission of SARS-CoV-2.
