Purpose The systematic review aims to analyze and summarize the characteristics of living systematic review (LSR) for coronavirus disease 2019 (COVID-19). Methods Six databases including Medline, Excerpta Medica (Embase), Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database and China Science, and Technology Journal Database (VIP), were searched as the source of basic information and methodology of LSR. Descriptive analytical methods were used to analyze the included COVID-19 LSRs, and the study characteristics of COVID-19 LSRs were further assessed. Results Sixty-four COVID-19 LSRs were included. Eighty-nine point one percent of LSRs were published on Science Citation Index (SCI) journals, and 64.1% publication with an impact factor (IF) >5 and 17.2% with an IF >15 among SCI journals. The first unit of the published LSRs for COVID-19 came from 19 countries, with the largest contribution from the UK (17.2%, 11/64). Forty point six percent of LSRs for COVID-19 were related to therapeutics topic which was considered the most concerned perspective for LSRs for COVID-19. Seventy-six point six percent of LSRs focused on the general population, with less attention to children, pregnant women and the elderly. However, the LSR for COVID-19 was reported incomplete on “living” process, including 40.6% of studies without search frequency, 79.7% of studies without screening frequency, 20.3% of studies without update frequency, and 65.6% of studies without the timing or criteria of transitioning LSR out of living mode. Conclusion Although researchers in many countries have applied LSRs to COVID-19, most of the LSRs for COVID-19 were incomplete in reporting on the “living” process and less focused on special populations. This could reduce the confidence of health-care providers and policy makers in the results of COVID-19 LSR, thereby hindering the translation of evidence on COVID-19 LSR into clinical practice. It was necessary to explicitly enact preferred reporting items for systematic reviews and meta-analyses (PRISMA) to improve the reporting quality of LSR and support ongoing efforts of therapeutics research for special patients with COVID-19.

“…Implementation should be feasible, at least with the freely available sources, such as PubMed, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform, assuming appropriate application programming interfac s (APIs) are in place. In addition, specialised databases such as the Cochrane COVID-19 Study Register and Epistemonikos’ L·OVE platform25 26 have helped to reduce sources to be searched when identifying evidence during the pandemic.…”

Living systematic reviews (LSRs) are an increasingly common approach to keeping reviews up to date, in which new relevant studies are incorporated as they become available, so as to inform healthcare policy and practice in a timely manner. While journal publishers have been exploring the publication of LSRs using different updating and publishing approaches, readers cannot currently assess if the evidence underpinning a published LSR is up to date, as neither the search details, the selection process, nor the list of identified studies is made available between the publication of updates. We describe a new method to transparently report the living evidence surveillance process that occurs between published LSR versions. We use the example of the living Cochrane Review on nirmatrelvir combined with ritonavir (Paxlovid) for preventing and treating COVID-19 to illustrate how this can work in practice. We created a publicly accessible spreadsheet on the Open Science Framework platform, linking to the living Cochrane Review, that details the search and study selection process, enabling readers to track the progress of eligible ongoing or completed studies. Further automation of the evidence surveillance process should be explored.

“…Our review was based on searches in the comprehensive WHO and Cochrane COVID-19 living data repositories, which employ robust search strategies to identify relevant studies. 9,10 Two reviewers were involved in each of the full-text screening, data extraction, and risk of bias steps of the analysis. However, the identified studies assessed only eight TGA-approved RATs, and we cannot comment on the diagnostic accuracy of other tests registered with the TGA.…”

ObjectivesTo review evaluations of the diagnostic accuracy of coronavirus disease 2019 (COVID‐19) rapid antigen tests (RATs) approved by the Therapeutic Goods Administration (TGA) for self‐testing by ambulatory people in Australia; to compare these estimates with values reported by test manufacturers.Study designSystematic review of publications in any language that reported cross‐sectional, case–control, or cohort studies in which the participants were ambulatory people in the community or health care workers in hospitals in whom severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection was suspected, and the results of testing self‐collected biological samples with a TGA‐approved COVID‐19 RAT were compared with those of reverse transcription–polymerase chain reaction (RT‐PCR) testing for SARS‐CoV‐2. Estimates of diagnostic accuracy (sensitivity, specificity) were checked and compared with manufacturer estimates published on the TGA website.Data sourcesPublications (to 1 September 2022) identified in the Cochrane COVID‐19 Study Register and the World Health Organization COVID‐19 research database. Information on manufacturer diagnostic accuracy evaluations was obtained from the TGA website.Data synthesisTwelve publications that reported a total of eighteen evaluations of eight RATs approved by the TGA for self‐testing (manufacturers: All Test, Roche, Flowflex, MP Biomedicals, Clungene, Panbio, V‐Chek, Whistling) were identified. Five studies were undertaken in the Netherlands, two each in Germany and the United States, and one each in Denmark, Belgium, and Canada; test sample collection was unsupervised in twelve studies, and supervised by health care workers or researchers in six. Estimated sensitivity with unsupervised sample collection ranged from 20.9% (MP Biomedicals) to 74.3% (Roche), and with supervised collection from 7.7% (V‐Chek) to 84.4% (Panbio); the estimates were between 8.2 and 88 percentage points lower than the values reported by the manufacturers. Test specificity was high for all RATs (97.9–100%).ConclusionsThe risk of false negative results when using COVID‐19 RATs for self‐testing may be considerably higher than apparent in manufacturer reports on the TGA website, with implications for the reliability of these tests for ruling out infection.
