Introduction
As of 3 June 2020, the World Health Organization (WHO) has reported more than 6 million confirmed cases of coronavirus disease 2019 (COVID-19) and 373,548 confirmed deaths in 216 countries around the world [1]. Recognising the shortage of healthcare facilities in low- and middle-income countries (LMICs) compared with developed countries, LMICs are likely to experience high mortality rates and detrimental effects on the economy [2]. To date, Malaysia has seen the number of COVID-19 cases increase to 7877, with a death toll of 115 [3]. Since its beginning in December 2019, the manifestations of pneumonia-like symptoms were confirmed to be caused by a novel type of coronavirus closely resembling the viruses that cause severe acute respiratory syndrome and Middle East respiratory syndrome. COVID-19 patients can develop rapidly worsening respiratory failure and acute respiratory distress syndrome [4].
Handling of the COVID-19 pandemic in Malaysian health facilities
Since 30 January 2020, the Malaysian Ministry of Health (MOH) has upgraded public hospitals and public health laboratories throughout the country to have the capacity to carry out real-time reverse transcriptase-polymerase chain reaction (RT-PCR) tests to detect COVID-19 [5]. As of 29 March 2020, the laboratory capacity in the country was expanded to 25 laboratories nationwide, including 18 MOH laboratories and 7 private laboratories [6]. Recently, the Ministry of Higher Education and the Ministry of Science, Technology and Innovation have set up 10 additional diagnostic laboratories at institutions of higher learning and university teaching hospitals to enhance COVID-19 testing capacity [6]. As of 4 April 2020, there are 43 laboratories and 18 hospitals available across the country that can conduct COVID-19 RT-PCR tests [7].
In Malaysia, RT-PCR tests for COVID-19 are only conducted in symptomatic patients, with samples for testing being taken at health care centres by qualified physicians, which are then transported to the nearby laboratories appointed by the MOH for further testing. To detect lower respiratory tract infection, samples are collected from the sputum, tracheal aspirate and bronchoalveolar lavage; for upper respiratory tract infection, nasopharyngeal and oropharyngeal swabs are taken. A single negative test result, particularly if the sample was collected from an upper respiratory tract, does not exclude COVID-19, and repeat sampling and testing are required. Taking samples from the lower respiratory tract is strongly recommended in patients with severe or progressive disease [8]. If samples are transported to nearby laboratories for testing for the presence of COVID-19 within 72 h, they are stored at 2–8 °C; if transportation takes longer than 72 h, the samples are stored at − 80 °C and transported in ice [9].
Introduction of rapid test kits (RTKs)
With the aim of increasing the number of daily COVID-19 tests from 11,500 to 16,500, the MOH recently procured 200,000 reliable rapid test kits (RTKs; Standard™ Q COVID-19 IgM/IgG Duo Test Kit®) [10] from the manufacturer (SD Biosensor, South Korea) [11]. This Standard™ Q COVID-19 IgM/IgG Duo Test Kit® has a sensitivity rate of 84.4% and specificity rate of 100%, and can be performed at any clinic, hospital or other centre equipped with biosafety cabinets [11]. As this test can be performed anywhere, its use in the national COVID-19 screening programme will not overload the existing 43 laboratories. Compared with RT-PCR tests, RTKs are easier to handle and the testing procedure is safer. Table 1 shows the differences in features between RT-PCR tests and RTKs.
Role of community pharmacists in screening and testing for COVID-19
Currently in Malaysia, COVID-19 screening and testing services are conducted at selected public hospitals and private hospitals. In an effort to extend the testing capacity, community pharmacies could play an important role in COVID-19 screening and testing. Community pharmacists comprise a unique and large body of healthcare professionals who have been trained at universities, work in the retail environment, are knowledgeable about diseases (including viral infections, drugs, and healthcare products), and closely communicate with other health professionals [15, 16]. Of note, community pharmacies are one of the essential healthcare services allowed to operate amid the ‘Movement Control Order’ in Malaysia. Currently, there are 2889 community pharmacies in Malaysia, with wide coverage in each state [17].
Community pharmacists are trusted healthcare professionals with established relationships with their patients. Most people live within close proximity to a community pharmacy, which could shorten the travel time to the COVID-19 testing sites, one of the key measures to mitigate virus transmission. Relative to other sites, testing at community pharmacies has the advantage of enhanced accessibility to the public, with extended operating hours and lack of the need for an appointment for consultation [18]. As they have strong relationships with medical providers and hospitals, community pharmacists could refer patients with suspected or positive Covid-19 for further assessment and medical care.
United States community pharmacists are already involved
Recently in the US, the Department of Health and Human Services has authorised community pharmacists to order and conduct COVID-19 tests, including serology tests [19]. Notably, the serology tests are solely used to detect antibodies to the virus and are less complex to be conducted relative to molecular tests [20]. ‘Drive-up’ testing with patients remaining in their cars during the evaluation is one of the suggested proper precautionary methods for performing COVID-19 testing in the US [21]. During this pandemic, the American Pharmacists Association has been giving very encouraging support to US community pharmacists by providing information regarding the Medicare and Medicaid Programs, policy and regulatory revisions in response to the COVID-19 public health emergency, and weekly webinar training and updates in addressing the COVID-19 crisis [22]. As healthcare professionals in primary care, community pharmacists in Malaysia are also well-positioned to aid in the expanded COVID-19 testing programme made possible by the governments’ procurement of RTK. For example, community pharmacies could set up ‘drive through’ COVID-19 testing sites in front of their premises, where community pharmacists and assistants would perform the RTK tests.
Take home messages
-
At present, RT-PCR and antibody testing (RTK) are the predominant ways to test for COVID-19, and have different sensitivities, handling procedures and results.
-
The screening rate in Malaysia is relatively low, with 11,500 COVID-19 tests per day in 43 national laboratories [11].
-
In the US, community pharmacists have shown that pharmacy-based testing services are acceptable to the healthcare system. However, the concept of Malaysian community pharmacies testing for COVID-19 has not yet been suggested or implemented.
-
Thus, a feasibility study on COVID-19 screening and testing services by using RTKs in community pharmacies, based on the concept of a drive-through service without entering the premises, should be conducted in Malaysia.
