Abstract
Improvements in diagnostic test accuracy across multiple pathogens have resulted in multi-viral point-of-care testing (POCT) via a rapid antigen test (RAT).
This study aimed to describe general practice practitioners’ reactions to a pilot respiratory virus surveillance programme during the SARS-CoV-2 pandemic, which enabled surveillance for influenza and other respiratory viruses alongside POCT for SARS-CoV-2.
Participating general practices collected viral swabs between May and December 2022. Nasopharyngeal swabs were taken for both an immediate COVID-19 RAT and a polymerase chain reaction (PCR) for testing SARS-CoV-2, influenza, respiratory syncytial virus (RSV) and other respiratory viruses. A questionnaire explored practitioners’ experiences and perceptions, addressing project setup, swabbing process and perceived overall value.
Of 4135 swabbed patients, 54% were positive for one of the tested viruses. Involved nurses and doctors reported high adaptability to the swabbing process. Clinicians valued obtaining rapid diagnostic information for patient management and patient communication. While no significant barriers were identified, practitioners acknowledged additional time requirements and potential challenges with swabbing young children.
The study demonstrated the feasibility and clinical utility of using POCT swabbing for immediate RAT and subsequent PCR testing for respiratory viruses in general practices when managing a viral pandemic. The data assisted in identifying community transmission of respiratory viruses, provided information for patient management and reinforced positive health messages about viral illnesses. The study suggests potential benefits for both individual patient care and population-based surveillance. The study also identified the potential value of multi-viral POCT testing via a RAT.
