Background Hearing loss affects access to spoken language, which can affect cognition and development, and can negatively affect social wellbeing. We present updated estimates from the Global Burden of Disease (GBD) study on the prevalence of hearing loss in 2019, as well as the condition's associated disability. Methods We did systematic reviews of population-representative surveys on hearing loss prevalence from 1990 to 2019. We fitted nested meta-regression models for severity-specific prevalence, accounting for hearing aid coverage, cause, and the presence of tinnitus. We also forecasted the prevalence of hearing loss until 2050. Findings An estimated 1•57 billion (95% uncertainty interval 1•51-1•64) people globally had hearing loss in 2019, accounting for one in five people (20•3% [19•5-21•1]). Of these, 403•3 million (357•3-449•5) people had hearing loss that was moderate or higher in severity after adjusting for hearing aid use, and 430•4 million (381•7-479•6) without adjustment. The largest number of people with moderate-to-complete hearing loss resided in the Western Pacific region (127•1 million people [112•3-142•6]). Of all people with a hearing impairment, 62•1% (60•2-63•9) were older than 50 years. The Healthcare Access and Quality (HAQ) Index explained 65•8% of the variation in national agestandardised rates of years lived with disability, because countries with a low HAQ Index had higher rates of years lived with disability. By 2050, a projected 2•45 billion (2•35-2•56) people will have hearing loss, a 56•1% (47•3-65•2) increase from 2019, despite stable age-standardised prevalence. Interpretation As populations age, the number of people with hearing loss will increase. Interventions such as childhood screening, hearing aids, effective management of otitis media and meningitis, and cochlear implants have the potential to ameliorate this burden. Because the burden of moderate-to-complete hearing loss is concentrated in countries with low health-care quality and access, stronger health-care provision mechanisms are needed to reduce the burden of unaddressed hearing loss in these settings.

Summary Background Achieving universal health coverage (UHC) involves all people receiving the health services they need, of high quality, without experiencing financial hardship. Making progress towards UHC is a policy priority for both countries and global institutions, as highlighted by the agenda of the UN Sustainable Development Goals (SDGs) and WHO's Thirteenth General Programme of Work (GPW13). Measuring effective coverage at the health-system level is important for understanding whether health services are aligned with countries' health profiles and are of sufficient quality to produce health gains for populations of all ages. Methods Based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we assessed UHC effective coverage for 204 countries and territories from 1990 to 2019. Drawing from a measurement framework developed through WHO's GPW13 consultation, we mapped 23 effective coverage indicators to a matrix representing health service types (eg, promotion, prevention, and treatment) and five population-age groups spanning from reproductive and newborn to older adults (≥65 years). Effective coverage indicators were based on intervention coverage or outcome-based measures such as mortality-to-incidence ratios to approximate access to quality care; outcome-based measures were transformed to values on a scale of 0–100 based on the 2·5th and 97·5th percentile of location-year values. We constructed the UHC effective coverage index by weighting each effective coverage indicator relative to its associated potential health gains, as measured by disability-adjusted life-years for each location-year and population-age group. For three tests of validity (content, known-groups, and convergent), UHC effective coverage index performance was generally better than that of other UHC service coverage indices from WHO (ie, the current metric for SDG indicator 3.8.1 on UHC service coverage), the World Bank, and GBD 2017. We quantified frontiers of UHC effective coverage performance on the basis of pooled health spending per capita, representing UHC effective coverage index levels achieved in 2019 relative to country-level government health spending, prepaid private expenditures, and development assistance for health. To assess current trajectories towards the GPW13 UHC billion target—1 billion more people benefiting from UHC by 2023—we estimated additional population equivalents with UHC effective coverage from 2018 to 2023. Findings Globally, performance on the UHC effective coverage index improved from 45·8 (95% uncertainty interval 44·2–47·5) in 1990 to 60·3 (58·7–61·9) in 2019, yet country-level UHC effective coverage in 2019 still spanned from 95 or higher in Japan and Iceland to lower than 25 in Somalia and the Central African Republic. Since 2010, sub-Saharan Africa showed accelerated gains on the UHC effective coverage index (at an average increase of 2·6% [1·9–3·3] per year up to 2019); by contrast,...
The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 provides a rules-based synthesis of the available evidence on levels and trends in health outcomes, a diverse set of risk factors, and health system responses. GBD 2019 covered 204 countries and territories, as well as first administrative level disaggregations for 22 countries, from 1990 to 2019. Because GBD is highly standardised and comprehensive, spanning both fatal and non-fatal outcomes, and uses a mutually exclusive and collectively exhaustive list of hierarchical disease and injury causes, the study provides a powerful basis for detailed and broad insights on global health trends and emerging challenges. GBD 2019 incorporates data from 281 586 sources and provides more than 3•5 billion estimates of health outcome and health system measures of interest for global, national, and subnational policy dialogue. All GBD estimates are publicly available and adhere to the Guidelines on Accurate and Transparent Health Estimate Reporting. From this vast amount of information, five key insights that are important for health, social, and economic development strategies have been distilled. These insights are subject to the many limitations outlined in each of the component GBD capstone papers.
Background:In nonvalvular atrial fibrillation (NVAF), rivaroxaban is used to prevent stroke and systemic embolism. Objective: To evaluate major bleeding (MB) in NVAF patients treated with rivaroxaban in a real-world clinical setting. Methods: From January 1, 2013, to March 31, 2014, US Department of Defense electronic health care records were queried to describe MB rates and demographics. Major bleeding was identified using a validated algorithm. Results: Of 27 467 patients receiving rivaroxaban, 496 MB events occurred in 478 patients, an incidence of 2.86 per 100 person-years (95% confidence interval: 2.61-3.13). The MB patients were older, mean (SD) age of 78.4 (7.7) vs 75.7 (9.7) years, compared with non-MB patients. Patients with MB had higher rates of hypertension (95.6% vs 75.8%), coronary artery disease (64.2% vs 36.7%), heart failure (48.5% vs 23.7%), and renal disease (38.7% vs 16.7%). Of MB patients, 63.2% were taking 20 mg, 32.2% 15 mg, and 4.6% 10 mg of rivaroxaban. Four percent of MB patients took warfarin within the prior 30 days. Major bleeding was most commonly gastrointestinal (88.5%) or intracranial (7.5%). Although 46.7% of MB patients received a transfusion, none had sufficient evidence of receiving any type of clotting factor. Fourteen died during their MB hospitalization, yielding a fatal bleeding incidence rate of 0.08 per 100 person-years (95% confidence interval: 0.05-0.14). Mean age at death was 82.4 years. Conclusions: In this large observational study, the MB rate was generally consistent with the registration trial results, and fatal bleeds were rare.
Objective: Parents of children with autism spectrum disorders (ASDs) often try a variety of treatments for their children, including complementary and alternative medicine (CAM). The objective of this study was to improve understanding of the frequency of CAM use by parents for their children with autism and to quantify the parents' perceived effectiveness of various CAM therapies in mitigating the health and functioning problems associated with autism. Methods: Parents in southeastern Virginia were recruited for study participation from local autism organizations and a clinical practice where a large proportion of the patients are children with autism. Parents completed an online survey and answered questions about CAM use for their children with autism, and they rated the perceived effectiveness of each therapy. Results: Of 194 parents surveyed, 80.9% reported that they had tried some form of CAM for their child with autism. Among CAM users, the most frequently used therapies were multivitamins (58.6%), the gluten-free casein-free diet (54.8%), and methyl B-12 injections (54.1%). The CAM therapies that received the highest average rating of effectiveness were sensory integration therapy, melatonin, and off-label use of prescription antifungal medications. Conclusion: CAM therapies were frequently used in this population, and many were perceived to be effective in helping to ease some of the health challenges associated with autism. CAM therapies for the autism population should be further studied in well-controlled clinical research settings to provide safety and efficacy data on treatments, as well as validated treatment options for those with ASD.
