Project description:AimCPR training for schoolchildren to increase bystander CPR-rates is widely applied. HCPs are regarded as the instructor gold standard, but using non-HCP instructors (e.g., peer-tutors, schoolteachers, medical students) challenges that. This systematic review assesses whether cardiopulmonary resuscitation (CPR) training for children led by peer-tutors, schoolteachers, or medical students results in different learning outcomes to training by health-care professionals (HCPs).MethodsWe searched studies that compared CPR training for schoolchildren (population) delivered by peer-tutors, schoolteachers, or medical students (intervention), with training led by HCPs (comparison), assessing student knowledge, skills, willingness and/or confidence to perform CPR (outcome). We included randomized and non-randomized controlled trials (study design). Medline, Embase, Psychinfo, Cinahl, Cochrane, Scopus, Web of Science, and Eric were searched from inception until December 23rd, 2023 (timeframe). Two independent reviewers performed title, abstract, full text screening, bias assessment, and grading of certainty of evidence. We followed the Preferred Reporting Items for a Systematic Review and Meta-Analysis (PRISMA) guidelines, and registered the review with PROSPERO.ResultsOf 9'092 studies identified, 14 were included. Comparison of intervention groups to HCP-led training showed similar overall results (knowledge, skills, self-confidence). Superior results for HCP training were only reported for 'ventilation volume', while schoolteachers and medical students achieved superior knowledge transfer. A meta-analysis was possible for 'compression depth' between peer-tutors and HCPs showing no significant differences. Certainty of evidence was 'low' to 'very low'.ConclusionThis systematic review of CPR training for school children revealed that peer-tutors, schoolteachers and medical students achieve similar educational outcomes compared to those of HCPs. Non-HCPs training schoolchildren is an appropriate cost-efficient alternative and easy to implement in school curricula.

Project description:We quantify the effect of statewide mask mandates in the United States in 2020. Our regression discontinuity design exploits county-level variation in COVID-19 outcomes across the border between states with and without mandates. State mask mandates reduced new weekly COVID-19 cases, hospital admissions, and deaths by 55, 11, and 0.7 per 100,000 inhabitants on average. The effect depends on political leaning with larger effects in Democratic-leaning counties. Our results imply that statewide mandates saved 87,000 lives through December 19, 2020, while a nationwide mandate could have saved 57,000 additional lives. This suggests that mask mandates can help counter pandemics, particularly if widely accepted.

Project description:Health insurance characteristics shift at age 65 as most people become eligible for Medicare. We measure the impacts of these changes on patients who are admitted to hospitals through emergency departments for conditions with similar admission rates on weekdays and weekends. The age profiles of admissions and comorbidities for these patients are smooth at age 65, suggesting that the severity of illness is similar on either side of the Medicare threshold. In contrast, the number of procedures performed in hospitals and total list charges exhibit small but statistically significant discontinuities, implying that patients over 65 receive more services. We estimate a nearly 1-percentage-point drop in 7-day mortality for patients at age 65, equivalent to a 20% reduction in deaths for this severely ill patient group. The mortality gap persists for at least 9 months after admission.

Project description:A wide variety of animals become completely immobile after initial contact with a potential predator. This behaviour is considered to be a last-ditch escape strategy. Here, we test the hypothesis that such immobility should have an extremely unpredictable duration. We find that it spans more than three orders of magnitude in antlion larvae. We also analyse the second period of immobility that follows the first bout of immobility, and consider the distributions of both first and second immobility periods within the context of the intermittence that characterizes the movement of most organisms. Both immobility durations were fitted best by exponential distributions. Therefore, both were characterized by high variability and hence, unpredictability. The immobility half-life, its mean duration and standard deviation were greater for the first than the second immobility. Furthermore, individual consistency was weak or absent in repeated measures of the first immobility and between the first and second immobilities. Our quantitative approach can be replicated across taxa and would help link an understanding of immobility after an initial predator contact in both vertebrates and invertebrates. To facilitate this, we contend that the terminology should be simplified, and we advocate the use of the term post-contact immobility (PCI).

Project description:ObjectivesThe aim of the study was to assess the impact of social distancing interventions in Greece and to examine what would have happened if those interventions had not been implemented.Study designA dynamic, discrete time, stochastic individual-based model was developed to simulate coronavirus disease 2019 (COVID-19) transmission.MethodsThe model was fitted to the observed trends in COVID-19 deaths and intensive care unit (ICU) bed use in Greece.ResultsIf Greece had not implemented social distancing interventions, the healthcare system would have been overwhelmed between March 30 and April 4. The combined social distancing interventions and increase in ICU beds averted 4360 (95% credible interval: 3050, 5700) deaths and prevented the healthcare system from becoming overwhelmed.ConclusionsThe quick and accurate interventions of the Greek government limited the burden of the COVID-19 outbreak.

Project description:This paper studies whether containing COVID-19 pandemic by stringent strategies deteriorates or saves economic growth. Since there are country-specific factors that could affect both economic growth and deaths due to COVID-19, we first start with a cross-country analysis on identifying risk and protective factors on the COVID-19 deaths using large across-country variation. Using data on 100 countries from 3 January to 27 November 2020 and taking into account the possibility of underreporting, we find that for deaths per million population, GDP per capita, population density, and income inequality are the three most important risk factors; government effectiveness, temperature, and hospital beds are the three most important protective factors. Second, inspired by the stochastic frontier literature, we construct a measure of pandemic containment effectiveness (PCE) after controlling for country-specific factors and rank countries by their PCE scores for deaths. Finally, by linking the PCE score with GDP growth data in Quarters 2 and 3 of 2020, we find that PCE is positively associated with economic growth in major economies. Countries with average PCE scores, such as Malaysia, would gain more GDP growth by 3.47 percentage points if they could improve their PCE scores for deaths to South Korea's level in Q2 of 2020. Therefore, there is not a trade-off between lives and livelihood facing by governments. Instead, to save economy, it is important to contain the pandemic first. Our conclusion is also mainly valid for infections due to COVID-19.
