Three articles, led by Oxford researchers in the department, including three DPhil students, make the top 10 list for the most read open research articles in the BJGP Open for 2020 - including number one.

Three images of Oxford researchers who make the BJGP Open's top 10 open research articles of 2020.


The number one most read open research article of 2020 is rapid review, 'Should Chloroquine and Hydroxychloroquine be used to treat COVID-19?', with the aim of establishing current evidence for the effectiveness of CQ and HCQ in treating COVID-19. The study, performed by department DPhil student, Kome Gbinigie, and former DPhil student, Kerstin Frie, concluded that there is insufficient evidence to determine whether CQ/HCQ are safe and effective treatments for COVID-19, and that high quality randomised clinical trials are urgently required to guide policymakers and clinicians.

Number two 

At number two, we have rapid review, 'Should Azithromycin be used to treat COVID-19?', reviewing the evidence to ascertain the effectiveness and safety of azithromycin in treating COVID-19. Also led by Kome Gbinigie and Kerstin Frie, concluded that there is no evidence to support the use of azithromycin for the treatment of COVID-19 outside of the context of clinical trials, unless it is used to treat bacterial super-infection, as well as extremely limited evidence of a possible synergy between azithromycin and hydroxychloroquine.

Number Five

The fifth most read open research article of 2020 is online survey, 'GP's understanding of the benefits and harms of treatments for long-term conditions', with the aim of measuring the level and range of the quantitative understanding of the benefits and harms of treatments for common long-term conditions (LTCs) among GPs. This study, led by the departments Professor of Primary Health Care, Trish Greenhalgh, and NIHR Doctoral Research Fellow, Julian Treadwell, concluded that GPs’ knowledge of the absolute benefits and harms of treatments is poor, with inaccuracies of a magnitude likely to meaningfully affect clinical decision-making and impede conversations with patients regarding treatment choices. Qualitative follow up out soon. More qualitative research is being done, working with fellow GP's and patients to co-design an information solution.
