Background Most countries have endorsed the WHO NCD 'best buy' policies but we know very little about global implementation patterns and which geopolitical factors might influence adoption. Methods We used the 2015 and 2017 WHO NCD progress monitor reports to calculate aggregate implementation scores for 151 countries, based on their implementation of 18 WHO-recommended NCD policies. We ranked all countries and used descriptive statistics to analyse global trends. We used linear regression to assess the associations between policy implementation and World Bank geographic region, risk of premature NCD mortality, percentage of all deaths caused by NCDs, World Bank income group, human capital index, democracy index, and tax burden. Findings In 2017, the mean NCD policy implementation score was 48.4% (SD 18.4%). Costa Rica and Iran had the joint-highest implementation scores (86.8% of all WHO-recommended policies). Scores were lowest in Haiti and South Sudan (5.3%). Between 2015 and 2017, aggregate implementation scores rose in 109 countries and regressed in 32 countries. Mean implementation rose for all of the 18 policies except for those targeting alcohol and physical activity. The most commonly implemented policies were clinical guidelines, graphic warnings on tobacco packaging, and NCD risk factor surveys. Our multiple linear regression model explained 61.1% of the variance in 2017 aggregate scores (p<0.001) but we found evidence of a high degree of collinearity between the explanatory variables. Interpretation Implementation of WHO-recommended NCD policies is increasing over time. In 2017 the average country had introduced just under half of the WHO-recommended measures. Polices relating to alcohol and physical activity were the most likely to have been dropped. Aggregate implementation scores tended to be highest in countries with healthier, wealthier and more educated populations.

Background Community health worker (CHW) programs are an important resource in the implementation of universal health coverage (UHC) in many low- and middle-income countries (LMICs). However, in countries with decentralized health systems like the Philippines, the quality and effectiveness of CHW programs may differ across settings due to variations in resource allocation and local politics. In the context of health system decentralization and the push toward UHC in the Philippines, the objective of this study was to explore how the experiences of CHWs across different settings were shaped by the governance and administration of CHW programs. Methods We conducted 85 semi-structured interviews with CHWs (n = 74) and CHW administrators (n = 11) in six cities across two provinces (Negros Occidental and Negros Oriental) in the Philippines. Thematic analysis was used to analyze the qualitative data with specific attention to how the experiences of participants differed within and across geographic settings. Results Health system decentralization contributed to a number of variations across settings including differences in the quality of human resources and the amount of financial resources allocated to CHW programs. In addition, the quality and provider of CHW training differed across settings, with implications for the capacity of CHWs to address specific health needs in their community. Local politics influenced the governance of CHW programs, with CHWs often feeling pressure to align themselves politically with local leaders in order to maintain their employment. Conclusions The functioning of CHW programs can be challenged by health system decentralization through the uneven operationalization of national health priorities at the local level. Building capacity within local governments to adequately resource CHWs and CHW programs will enhance the potential of these programs to act as a bridge between the local health needs of communities and the public health system.

Background: During the COVID-19 pandemic in 2020, the UK government began a mass SARS-CoV-2 testing programme. This study aimed to determine the feasibility and acceptability of organised regular self-testing for SARS-CoV-2. Methods: This was a mixed methods observational cohort study in asymptomatic students and staff at University of Oxford, who performed SARS-CoV-2 antigen lateral flow self-testing. Data on uptake and adherence, acceptability, and test interpretation were collected via a smartphone app, an online survey, and qualitative interviews. Findings: Across three main sites, 551 participants (25% of those invited) performed 2728 tests during a follow-up of 5.6 weeks. 447 participants (81%) completed at least two, and 340 (62%) completed at least four tests. The survey, completed by 214 participants (39%), found that 98% of people were confident to self-test and believed self-testing to be beneficial. Acceptability of self-testing was high, with 91% of ratings being acceptable or very acceptable. 2711 (99.4%) test results were negative, nine were positive and eight were inconclusive. Results from eighteen qualitative interviews with students and staff revealed that participants valued regular testing, but there were concerns about test accuracy that impacted uptake and adherence. Interpretation: This is the first study to assess feasibility and acceptability of regular SARS-CoV-2 self-testing. It provides evidence to inform recruitment, adherence to, and acceptability of regular SARS-CoV-2 self-testing programmes for asymptomatic individuals using lateral flow tests. We found that self-testing is acceptable and people were able to interpret results accurately.
