In addition to dispensing and medication management, pharmacists are poised during the coronavirus disease 2019 (COVID-19) pandemic to provide preventive health services, including self-care recommendations and vaccinations.

 Many pharmacists may also use “waived” testing as designated by the FDA’s Clinical Laboratory Improvement Amendments (CLIA) to detect and aid in their decisions of disease management.

Pharmacists have an excellent opportunity to further evolve their role via point-of-care testing (POCT), especially considering the pressure that COVID-19 has placed on the health care system.

 Proper training, certification, and advances in testing technology enable POCT to occur in any setting.

The following outlines steps for pharmacists to get started as well as the opportunities that lie ahead. We also discuss the impact that pharmacists can make and the aid they can offer in triaging, assessing, and treating patients with minor ailments, as the United States continues to tread through this pandemic.

In the United States, 490,600 individuals were hospitalized and approximately 34,200 died from influenza during the 2018 to 2019 season.

 During the 2020 to 2021 influenza season, coinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, is a significant possibility. Both viruses cause respiratory symptoms, ranging from asymptomatic to severe, and they may be difficult to initially distinguish based on symptoms alone.

 The course of illness for influenza and SARS-CoV-2 is also similar during the first 5 days, with cough and fever being the most common symptoms.

Therefore, early detection is important to guide subsequent treatment decisions.

 Community pharmacies can administer rapid POCT for COVID-19 and influenza to help reduce emergency department (ED) visits.

 With early recognition, outbreak precautions/ preventative measures as well as supportive care can be put in place for COVID-19.

 Likewise, for influenza, antiviral therapy is most likely to provide benefit when initiated within the first 48 hours of illness.

Pharmacists using collaborative practice agreements based upon CLIA-POCT results have shown to provide efficacious and safe disease management of acute bacterial and viral conditions, such as furnishing oseltamivir for influenza.

 With a negative test, pharmacists can provide OTC recommendations for symptom relief. In addition, pharmacists have shown lower rates of inappropriate antimicrobial use under these influenza management programs.

Additional opportunities for POCT include cholesterol panels, hepatitis C, glycated hemoglobin, HIV, international normalized ratio, and group A 

To get started, the pharmacy must enroll as a CLIA-waived testing site through the Centers for Medicare & Medicaid Services (CMS). The CMS-116

 form is an application that is mailed to the pharmacy’s state agency.

 Furthermore, CMS outlines a complete guide on how to obtain a CLIA certificate of waiver

 and register as a laboratory. The National Association of Chain Drug Stores offers a certificate training program for pharmacists on POCT. The training includes disease-state education, (eg, group A Streptococcus pyogenes, hepatitis C, and HIV), health assessments, information and practice models regarding collaborative practice agreements, physical assessments, and POCT procedures.

Although POCT provides results in a short time frame, the results may be limited in terms of their sensitivity and specificity and may be subject to false-negative or false-positive results. Therefore, it is vital that the pharmacist properly interpret these results. Understanding the differences in negative predictive value, positive predictive value, sensitivity, and specificity (Table 1) allows pharmacists to better educate patients about their results.

 To minimize false results, it is advisable to collect specimens as early into the illness onset as possible, follow manufacturers’ instructions, and follow up negative results with confirmatory tests if a laboratory influenza diagnosis is needed.

To provide POCT safely, pharmacists must minimize the risk of exposure to SARS-CoV-2 by implementing safety standards to reduce the risk of transmission. In addition to adhering to personal protective equipment recommendations, engineering controls, and cleaning protocols as outlined by the CDC,

 pharmacists should also use proper infection control practices when collecting and handling specimens, including the following

Change gloves and sanitize hands between every specimen collection and after adding specimens to the testing device.

Decontaminate any instruments used to perform testing according to the manufacturer’s recommendations.

Handle laboratory waste as biohazardous waste.

Collect the specimen, and then maintain at least 6 feet of separation from the person from whom the specimen was collected. Or maintain 6 feet of separation while supervising onsite self-collection.

Use preprinted labels to identify the name of the patient, the assigned identification number, date of birth, date of specimen, and specimen type.

The pharmacy continues to be an ideal place for health care advice, and pharmacists will continue to be sought out for recommendations of OTC treatments. Community pharmacists are equipped with the knowledge and training to assess these common self-limiting or uncomplicated conditions.

 Such minor ailments may include allergies, colds, coughs, and pain. Many colds and respiratory disorders present with similar signs and symptoms that may be differentiated by specific defining characteristics as outlined in Table 2.

 In addition, many of these colds and respiratory disorders have common signs and symptoms with COVID-19. In triaging, assessing, and providing health advice and education, pharmacists will help relieve pressure on the health care system during the pandemic,

 and the pharmacy will further become a destination where patients can seek medical attention without putting pressure on ED and urgent-care centers.

Pharmacists should contribute to improving public health through patient care services, including disease self-care and support, medication monitoring, patient education, POCT, and vaccinations. The role of the pharmacist is evolving in patient care, and using CLIA-waived tests in the community pharmacy setting is an opportunity to advance the profession and aid in disease management during COVID-19. Under a collaborative practice agreement, pharmacists can provide a rapid response by offering prescription treatments, such as antivirals like oseltamivir for influenza, or referring patients to their primary care physicians or elsewhere for further care. Finally, consumers continue to suffer from self-limiting ailments, and the community pharmacy is equipped to provide them with care and education. Ultimately, the role of the pharmacist in patient care has broadened during the pandemic, and the community pharmacy has become a destination for patients with a variety of ailments.
