Community pharmacy rapid influenza A and B screening: A novel approach to expedite patient access to care and improve clinical outcomes.

objectiveTo investigate the impact and feasibility of community pharmacist-directed influenza screening and to evaluate the proportion of influenza-positive cases that resulted in the initiation of antiviral therapy by pharmacists.

methodsPatients aged 5 and older with symptoms suggestive of influenza were recruited at 2 Shoppers Drug Mart locations in Toronto, Ontario, from December 12, 2014, to February 4, 2015. Nasal swabs were collected by pharmacists and screened using the BD Veritor system for Rapid Detection of Flu A+B. Positive tests for influenza were reported to patients' physicians and recommendations for antiviral therapy were made when indicated. Supportive care recommendations and telephone follow-up within 48 hours of assessment were provided to all patients.

resultsA total of 59 patients participated in the influenza screening program. Sixty-one percent of patients were at high risk for influenza-related complications, while 15% had more than one risk factor. Thirty-four percent of patients screened positive for influenza, of which 100% were influenza A. Of the patients who screened positive, a prescription for oseltamivir was obtained in 40% of cases. The majority of prescriptions were provided directly to the pharmacy (63%), while the balance was provided after the patients underwent medical examination at the request of their physicians (37%). The pharmacy team offered supportive care to all patients for symptom management. Over-the-counter pharmacotherapy was provided to 85% of patients.

conclusionThese results highlight the readiness of community pharmacists to participate in the management of patients with influenza and their ability to implement screening into pharmacy workflow. Community pharmacy-based influenza screening may facilitate prompt access to pharmacologic treatment for patients with influenza, as well as decrease burden on the health care system by redirecting influenza-negative patients from physicians' offices and hospitals. Timely physician communication remains a barrier to access to treatment, suggesting a potential key role for advanced pharmacist prescribing. Can Pharm J (Ott) 2016;149:83-89.
