Implementing PCR testing in general practice – a qualitative study using normalization process theory

Abstract

Abstract Background The covid-19 pandemic brought attention to a need of rapid testing of large populations. Experiences from community-based testing settings show that there can be workload difficulties, logistical challenges, and socioeconomic downsides to large scale Polymerase Chain Reaction (PCR) testing. Alternative testing arenas have therefore been considered. Rapid point-of-care (POC) PCR test methods have since been developed and could have potential to surveille respiratory viral infections. It is, however, unknown if PCR testing can be successfully implemented routinely in general practice. The aim of this study is therefore to asses factors that enable and inhibit the implementation of point-of-care PCR testing for acute respiratory tract infection in general practice. Methods Fourteen general practices in the east Zealand area in Denmark were included in the study and given access to point-of-care PCR testing equipment during a flu season. The participating clinics were initially trained in the use of a POC PCR testing device and then spent 6 weeks testing it. We conducted qualitative interviews with general practitioners (GPs) and their staff, before and after the testing period, specifically focusing on their clinical decision-making and internal collaboration in relation to POC PCR testing. We used normalization process theory to design the interview guides and to analyze the data. Results Professionals reported no clinical need for a POC PCR testing device in a non-pandemic clinical setting. Results were delivered faster, but this was only timesaving for the patient and not the GP, who had to perform more tasks. Conclusion In its current form, the added diagnostic value of using a POC PCR tester in clinical practice does not justify the increased work connected to the usage of the diagnostic procedure in daily practice.
