ObjectiveTo review the evidence on the effectiveness of public health measures in reducing the incidence of covid-19, SARS-CoV-2 transmission, and covid-19 mortality.DesignSystematic review and meta-analysis.Data sourcesMedline, Embase, CINAHL, Biosis, Joanna Briggs, Global Health, and World Health Organization COVID-19 database (preprints).Eligibility criteria for study selectionObservational and interventional studies that assessed the effectiveness of public health measures in reducing the incidence of covid-19, SARS-CoV-2 transmission, and covid-19 mortality.Main outcome measuresThe main outcome measure was incidence of covid-19. Secondary outcomes included SARS-CoV-2 transmission and covid-19 mortality.Data synthesisDerSimonian Laird random effects meta-analysis was performed to investigate the effect of mask wearing, handwashing, and physical distancing measures on incidence of covid-19. Pooled effect estimates with corresponding 95% confidence intervals were computed, and heterogeneity among studies was assessed using Cochran’s Q test and the I2 metrics, with two tailed P values.Results72 studies met the inclusion criteria, of which 35 evaluated individual public health measures and 37 assessed multiple public health measures as a “package of interventions.” Eight of 35 studies were included in the meta-analysis, which indicated a reduction in incidence of covid-19 associated with handwashing (relative risk 0.47, 95% confidence interval 0.19 to 1.12, I2=12%), mask wearing (0.47, 0.29 to 0.75, I2=84%), and physical distancing (0.75, 0.59 to 0.95, I2=87%). Owing to heterogeneity of the studies, meta-analysis was not possible for the outcomes of quarantine and isolation, universal lockdowns, and closures of borders, schools, and workplaces. The effects of these interventions were synthesised descriptively.ConclusionsThis systematic review and meta-analysis suggests that several personal protective and social measures, including handwashing, mask wearing, and physical distancing are associated with reductions in the incidence covid-19. Public health efforts to implement public health measures should consider community health and sociocultural needs, and future research is needed to better understand the effectiveness of public health measures in the context of covid-19 vaccination.Systematic review registrationPROSPERO CRD42020178692.
Background Targeted lung cancer screening is effective in reducing mortality by upwards of twenty percent. However, screening is not universally available and uptake is variable and socially patterned. Understanding screening behaviour is integral to designing a service that serves its population and promotes equitable uptake. We sought to review the literature to identify barriers and facilitators to screening to inform the development of a pilot lung screening study in Scotland. Methods We used Arksey and O’Malley’s scoping review methodology and PRISMA-ScR framework to identify relevant literature to meet the study aims. Qualitative, quantitative and mixed methods primary studies published between January 2000 and May 2021 were identified and reviewed by two reviewers for inclusion, using a list of search terms developed by the study team and adapted for chosen databases. Results Twenty-one articles met the final inclusion criteria. Articles were published between 2003 and 2021 and came from high income countries. Following data extraction and synthesis, findings were organised into four categories: Awareness of lung screening, Enthusiasm for lung screening, Barriers to lung screening, and Facilitators or ways of promoting uptake of lung screening. Awareness of lung screening was low while enthusiasm was high. Barriers to screening included fear of a cancer diagnosis, low perceived risk of lung cancer as well as practical barriers of cost, travel and time off work. Being health conscious, provider endorsement and seeking reassurance were all identified as facilitators of screening participation. Conclusions Understanding patient reported barriers and facilitators to lung screening can help inform the implementation of future lung screening pilots and national lung screening programmes.
BackgroundThe Joint Committee on Vaccination and Immunisation in the United Kingdom requested an evidence synthesis to investigate the relationship between asthma and coronavirus disease 2019 (COVID-19) outcomes.ObjectiveWe conducted a systematic review and meta-analysis to summarise evidence on the risk of severe COVID-19 outcomes in people with uncontrolled asthma or markers of asthma severity.MethodsHigh-dose inhaled corticosteroids (ICS) or oral corticosteroids (OCS) were used as markers of asthma severity, following international or national asthma guidelines. Risk of bias was assessed using Joanna Briggs Institute tools. Adjusted point estimates were extracted for random-effects meta-analyses and subgroup analyses.ResultsAfter screening, 12 studies (11 in adults and one in children) met the eligibility criteria. Adults using high-dose ICS or OCS had a pooled adjusted hazard ratio (aHR) of 1.33 (95% CI 1.06–1.67, I2=0%) for hospitalisation and an aHR of 1.22 (95% CI 0.90–1.65, I2=70%) for mortality for COVID-19. We found insufficient evidence for associations between markers on COVID-19 mortality in the subgroup analyses.ConclusionsAdults with severe asthma are at increased risk of COVID-19 hospitalisation compared to nonusers. Our analysis highlighted the dearth of studies in children with asthma investigating serious COVID-19 outcomes.
Introduction: Targeted lung cancer screening is effective in reducing lung cancer and all-cause mortality according to major trials in the United Kingdom and Europe.However, the best ways of implementing screening in local communities requires an understanding of the population the programme will serve. We undertook a study to explore the views of those potentially eligible for, and to identify potential barriers
Introduction Despite the growing evidence on patient and public involvement (PPI) in health research, little emphasis has been placed on understanding its quality and appropriateness to evidence synthesis (ES) and systematic reviews (SR). This study aimed to synthesise qualitative evidence on the benefits, challenges, and best practices for PPI in ES/SR projects from the perspectives of patients/public and researchers. Methods We searched Ovid MEDLINE, Ovid EMBASE, Cochrane Library and CINAHL Plus. We also searched relevant grey literature and conducted hand‐searching to identify qualitative studies which report the benefits and challenges of PPI in individual ES/SR projects. Studies were independently screened by two reviewers for inclusion and appraised using the Joanna Briggs Institute's Qualitative Tool. Included studies were synthesised narratively using thematic synthesis. Results The literature search retrieved 9923 articles, of which eight studies were included in this review. Five themes on benefits emerged: two from patients'/public's perspective—gaining knowledge, and empowerment; and three from researchers' perspective—enhancing relevance, improving quality, and enhancing dissemination of findings. Six themes on challenges were identified: three from patients'/public's perspective—poor communication, time and low self‐esteem; and three from researchers' perspective—balancing inputs and managing relations, time, and resources and training. Concerning recommendations for best practice, four themes emerged: provision of sufficient time and resources, developing a clear recruitment plan, provision of sufficient training and support, and the need to foster positive working relationships. Conclusion Highlighting the benefits and challenges of PPI in ES/SR projects from different stakeholder perspectives is essential to understand the process and contextual factors and facilitate meaningful PPI in ES/SR projects. Future research should focus on the utilisation of existing frameworks (e.g., Authors and Consumers Together Impacting on eVidencE [ACTIVE] framework) by researchers to help describe and/or report the best approaches and methods for involving patients/public in ES/SRs projects. Patient and Public Contribution This review received great contributions from a recognised PPI partner, the Chair of the Cochrane Consumer Network Executive, to inform the final stage of the review (i.e., interpretation, publication and dissemination of findings). The PPI partner has been included as an author of this review.
