“NEVER LET A CRISIS GO TO WASTE”: HOW SCIENCE HAS RESPONDED TO THE COVID-19 PANDEMIC

PMCID: PMC7964248  PMID: 33741124

This March marks a year since Covid-19 lockdowns were instituted in many countries. JCE put out a call for articles that address methodological challenges to studying the COVID-19 pandemic crisis [1]. We have received 322 submissions to-date and have published the 20 shown in Table 1 . Whilst not wishing in any way to minimise the morbidity and mortality impact of the pandemic, the articles demonstrate that in in the midst of a global crisis the clinical epidemiologic community has responded with energy and considerable imagination. This is exemplified by a number of major clinical COVID-19 programmatic initiatives that are meaningfully influencing practice and commentary policy. As Djulbegovic and Guyatt describe in their editorial, ‘the application of EBM and GRADE is never more important than in times of health crisis affecting millions of people.’ [2]

Systematic review organisations and their processes have frequently been criticised, with good reason, as being too slow to respond. However, it is now clear that not only can traditional reviews be produced rapidly as shown by Clark and colleagues [3], but indeed ‘living evidence’ can be operationalised for a rapidly changing field such as the COVID-19 pandemic. It is not just evidence synthesis that can be greatly accelerated. This is exemplified by examples such as the work presented by the Tendal et al paper in this issue on the Australian living guidelines for care of people with COVID-19.[4] The authors report on the production and maintenance of over 90 treatment recommendations by a large inter-disciplinary network. Although the guidelines have been published and updated at speed, it is noteworthy that those from vulnerable communities have been heavily involved in the process. Such diversity of representation is surely of great importance to successful implementation and perceived credibility.

There have been many other laudable initiatives launched that perform complementary tasks at all stages of the evidence eco-system: from prioritisation, study mapping, to evidence synthesis, to guidelines through to decision support. Many of these are ‘living’ programmes, updated as the evidence changes and new data emerge. Other organisations act as aggregators of content so that decision makers may have rapid access to the high quality, up to date information they need.

The COVID-19 pandemic has highlighted known challenges, but has also demonstrated new ones and novel solutions. As the study by Alexander et al demonstrates, despite the laudable, often heroic work by researchers and academics in the eye of the storm to conduct trials and conduct reviews, many of the published studies were small, lacked quality and indeed exemplified distorted prioritisation processes. [5] This has led to unwarranted duplication of effort and avoidable gaps in the evidence, but as Page et al demonstrate in their paper, it is also true that there are many scenarios where replicating syntheses is warranted [6].

The COVID-19 pandemic has shown par excellence the catastrophic health consequences of inequity. Within and between countries there has been marked and shameful disparity in outcomes between rich and poor, between protected and vulnerable communities. As we write this, the issue is playing out in respect of access to immunisation. All of this demonstrates the importance of researchers studying the issue of equity and is exemplified by the paper from Glover and colleagues describing a framework for identifying and mitigating the equity harms of policy interventions during the pandemic [7].

This pandemic is far from being over. However, it is clear that lessons need to be learned that will have implications for other spheres of health and illness, and also for building individual and societal resilience ahead of the next outbreak. The Journal of Clinical Epidemiology has an important role in supporting the ‘advancement and application of innovative methods’ aimed at improving the evidence eco-system and thus, the care and well being of communities.
