Background
Cochrane, an organization dedicated to the production and dissemination of high-quality evidence on health, endeavors to reach consumers by developing appropriate summary formats of its systematic reviews. However, the optimal type of presentation of evidence to consumers is still unknown.
Objective
The aim of this study was to investigate consumer preferences for different summary formats of Cochrane systematic reviews (CSRs), using both qualitative and quantitative approaches.
Methods
Initially, we conducted three focus groups with medical students (n = 7), doctors (n = 4), and patients (n = 9) in 2017 to explore their health information search habits and preferences for CSR summary formats. Based on those findings, we conducted a randomized trial with medical students at the University of Split School of Medicine, Croatia, and with patients from three Dalmatian family practices to determine whether they prefer CSR blogshots (n = 115) or CSR plain language summaries (PLSs; n = 123).
Results
Participants in the focus groups favored brief and explicit CSR summary formats with fewer numbers. Although we found no difference in participants’ preferences for a specific summary format in the overall sample, subgroup analysis showed that patients preferred blogshots over PLSs in comparison to medical students (P = 0.003, eta squared effect size η2 = 0.04).
Conclusion
CSR summaries should be produced in a format that meets the expectations and needs of consumers. Use of blogshots as a summary format could enhance the dissemination of CSRs among patients.
Trial registration
The trial was registered in ClinicalTrials.gov, NCT03542201. Registered on May 31st 2018.
