Diagnostic performance of the Idylla™ respiratory panel for molecular detection of influenza A/B in patients presenting to primary care with influenza-like illness during 3 consecutive influenza seasons.

BACKGROUND: Influenza virus (IFV) is often encountered in primary care. Implementation of a rapid diagnostic test for its detection at the point-of-care would enable discrimination from other viral causes of influenza-like-illness (ILI) and might be helpful in individual patient management. In this study, the diagnostic performance of such a point-of-care platform was evaluated. METHODS: Respiratory samples (n = 1490) from ILI-patients in primary care in 15 European countries were collected as part of a prospective clinical trial. Both children (n = 252) and adults (n = 1238) were sampled during 3 consecutive periods of high IFV endemicity. Samples were analysed in a central laboratory, after storage at -70 °C, with the Idylla™ Respiratory Panel, detecting both IFV and RSV, on the Idylla™ platform. The Fast Track Diagnostics (FTD) Respiratory Pathogens 21 plus assay was used as reference. A subset of samples (n = 192) was analysed both fresh and after being frozen. RESULTS: The reference method detected IFV-A in 42% and IFV-B in 13% of the samples. Sensitivity of the Idylla for detection of IFV-A and IFV-B was 98.2% and 92.3% and specificity 97.7% and 98.4% respectively. False negative samples contained significantly lower viral loads than true positive samples (FTD mean Ct-value 30.7 versus 26.1 for IFV-A and 30.4 versus 25.1 for IFV-B, p < 0.001). Comparable results were obtained for Idylla analysis using fresh and frozen samples. CONCLUSIONS: The Idylla Respiratory Panel is a promising point-of-care test for detection of IFV in ILI patients due to its excellent diagnostic performance, minimal training requirements and limited hands-on time.

Transformation of primary care during the COVID-19 pandemic: experiences of healthcare professionals in eight European countries.

BACKGROUND: Primary care has a crucial role in responding to the COVID-19 pandemic as the first point of patient care and gatekeeper to secondary care. Qualitative studies exploring the experiences of healthcare professionals during the COVID-19 pandemic have mainly focused on secondary care. AIM: To gain an understanding of the experiences of European primary care professionals (PCPs) working during the first peak of the COVID-19 pandemic. DESIGN AND SETTING: An exploratory qualitative study, using semi-structured interviews in primary care in England, Belgium, the Netherlands, Ireland, Germany, Poland, Greece, and Sweden, between April and July 2020. METHOD: Interviews were audiorecorded, transcribed, and analysed using a combination of inductive and deductive thematic analysis techniques. RESULTS: Eighty interviews were conducted with PCPs. PCPs had to make their own decisions on how to rapidly transform services in relation to COVID-19 and non-COVID-19 care. Despite being overwhelmed with guidance, they often lacked access to practical training. Consequently, PCPs turned to their colleagues for moral support and information to try to quickly adjust to new ways of working, including remote care, and to deal with uncertainty. CONCLUSION: PCPs rapidly transformed primary care delivery despite a number of challenges. Representation of primary care at policy level and engagement with local primary care champions are needed to facilitate easy and coordinated access to practical information on how to adapt services, ongoing training, and access to appropriate mental health support services for PCPs. Preservation of autonomy and responsiveness of primary care are critical to preserve the ability for rapid transformation in any future crisis of care delivery.
