Estimated reductions in type 2 diabetes burden through nutrition policies in AZAR cohort population: A PRIME microsimulation study for primary health care.

Background: Given the impact of high intake of sugar-sweetened beverages on type 2 diabetes, intervention to reduce their consumption can be a top priority for any health system. Thus, the purpose of the present study is to simulate the impact of policy options related to reduce consumption of sugar-sweetened beverages (SSBs) on the prevalence and mortality of type 2 diabetes in Iranian men and women. Methods: A discrete event simulation (DES) model was used to predict the effect of several policy options on the prevalence and death from type 2 diabetes in Azar Cohort Databases. Population age- and sex-specific prevalence and incidence rate of diagnosed diabetes were derived from the national health data. The Preventable Risk Integrated Model (PRIME) model was used for coding the input parameters of simulation using R and Python software. Results: The prevalence and mortality rate of type 2 diabetes under the scenario of reduced consumption of SSBs indicated that the highest and the lowest prevalence and mortality rates of type 2 diabetes for men and women were related to no policy condition and replacing SSBs with healthy drinks, like water, respectively. Also, the maximum "number of deaths postponed/ prevented" from type 2 diabetes was related to replacing SSBs with water (n=2015), and an integration of reformulation and applying 10% tax on SSBs (n=1872), respectively. Conclusion: Simulating the effect of different policy options on reducing the consumption of SSBs showed "replacing of SSBs with water" as the most effective policy option in Iranian setting.

Reforms and innovations in primary health care in different countries: scoping review.

INTRODUCTION: The World Health Organization (WHO) recommends focusing on primary health care (PHC) as the first strategy of countries to achieve the improvement of the health level of communities and has emphasized it again in 2021. Therefore, we intend to take a different look at the PHC system with reform, innovation, and initiative by using the experiences of leading countries and identify practical and evidence-based solutions to achieve greater health. METHODS: This is a scoping review study that has identified innovations and reforms related to PHC since the beginning of 2000 to the end of 2022. In this study, Scopus, Web Of Science, and PubMed databases have been searched using appropriate keywords. This study is done in six steps using Arkesy and O'Malley framework. In this study, the framework of six building blocks of WHO was used to summarize and report the findings. RESULTS: By searching in different databases, we identified 39426 studies related to reforms in primary care, and after the screening process, 106 studies were analyzed. Our findings were classified and reported into 9 categories (aims, stewardship/leadership, financing & payment, service delivery, health workforce, information, outcomes, policies/considerations, and limitations). CONCLUSION: The necessity and importance of strengthening PHC is obvious to everyone due to its great consequences, which requires a lot of will, effort, and coordination at the macro-level of the country, various organizations, and health teams, as well as the participation of people and society.

Key factors affecting health promoting behaviors among adolescents: a scoping review.

BACKGROUND: Health-promoting behaviors have been noticed recently as one of the most critical factors in raising life expectancy, which can be formed during adolescence. Thus, the current scoping review aimed to identify the key factors affecting health-promoting behaviors among adolescents. METHODS: In this scoping review, we searched multiple English online databases, including PubMed, Web of Science, Science Direct, ProQuest, and Scopus, for articles published between 1977 and 2020. All eligible studies describing health-promoting behaviors in adolescents were included. We followed the JBI guideline for conducting a scoping review and increasing the study's rigor. Extracted data were synthesized through inductive approaches. RESULTS: A total of 3199 articles were identified during the first phase. After the screening process, 20 articles were found eligible for final inclusion. Educational factors (individualized education and school health promotion programs), Economic factors (income, economic incentives and national health insurance), Social factors (support system, responsibility and peers), Spiritual, Psychological and Personal factors (gender, family structure, patterns of living, and medical problems) were found effective in health-promoting behaviors among adolescents. CONCLUSIONS: Health-promoting behaviors among adolescents require careful consideration. The current review identified some fundamental factors affecting health-promoting behaviors in adolescents. Based on the findings, it is recommended that policymakers and healthcare providers develop several interventions based on identified factors to increase adolescent's health-promoting behaviors among adolescents.

Impacts of accreditation on the performance of primary health care centres: A systematic review.

Introduction: Evidence on the impacts of accreditation on primary health care (PHC) services is inconsistent. Thus, this study aimed to assess the impacts of accreditation on the performance of PHC centres. Method: This study systematically reviewed articles published from 2000 to 2019 in the Web of Science, Scopus, ScienceDirect, Springer, PubMed and ProQuest. The following keywords were used: ((primary care OR primary health care) AND (accreditation) AND (impact OR effect OR output OR outcome OR influence OR result OR consequences)). The database search yielded a total of41256 articles, among which 30 articles were finally included in the review. Results: Accreditation showed the most positive impacts on the quality, effectiveness, human resource management and strategic management of PHC services. Accreditation also positively affected safety, responsiveness, accessibility, customer satisfaction, documentation, leadership, efficiency and continuity of care. Few negative impacts were noted, including the possibility of accreditation being used as a bureaucratic tool, high cost of acquiring accreditation, difficulties in understanding the accreditation process, high staff turnover rate in accredited PHC centres and weak sustainability of some accreditation programmes. Conclusion: Given its numerous positive impacts, accreditation could be used to effectively improve the performance of PHC centres.

Costs of inpatient care and out-of-pocket payments for COVID-19 patients: A systematic review.

OBJECTIVE: To identify the costs of hospital care for patients with COVID-19 and the amount of out-of-pocket payments. METHODS: We conducted a systematic review using Scopus and WEB OF SCIENCE and PubMed databases in April 5, 2022 and then updated in January 15, 2023. English articles with no publication year restrictions were included with study designs of cost-of-illness (COI) studies, cost analyses, and observational reports (cross-sectional studies and prospective and retrospective cohorts) that calculated the patient-level cost of care for COVID-19. Costs are reported in USD with purchasing power parity (PPP) conversion in 2020. The PROSPERO registration number is CRD42022334337. RESULTS: The results showed that the highest total cost of hospitalization in intensive care per patient was 100789 USD, which was reported in Germany, and the lowest cost was 5436.77 USD, which was reported in Romania. In the present study, in the special care department, the highest percentage of total expenses is related to treatment expenses (42.23 percent), while in the inpatient department, the highest percentage of total expenses is related to the costs of hospital beds/day of routine services (39.07 percent). The highest percentage of out-of-pocket payments was 30.65 percent, reported in China, and the lowest percentage of out-of-pocket payments was 1.12 percent, reported in Iran. The highest indirect cost per hospitalization was 16049 USD, reported in USA, and the lowest was 449.07 USD, reported in India. CONCLUSION: The results show that the COVID-19 disease imposed a high cost of hospitalization, mainly the cost of hospital beds/day of routine services. Studies have used different methods for calculating the costs, and this has negatively impacted the comparability costs across studies. Therefore, it would be beneficial for researchers to use a similar cost calculation model to increase the compatibility of different studies. Systematic review registration: PROSPERO CRD42022334337.

Developing Iranian sub-national primary health care measurement framework: a mixed-method study.

BACKGROUND: Desired health outcomes are more achievable through strong Primary Health Care (PHC). Using comprehensive and scientific tools, decision-makers are guided to formulate better PHC reforms and policies. This study introduces a sub-national framework based on the World Health Organization (WHO) proposed frameworks for the PHC performance measurement. METHOD: By a mixed-method and qualitative approach, the Iranian sub-national PHC Measurement Framework (PHCMF) was developed through a review of the WHO's PHC measurement conceptual framework (for selecting Key Performance Indicators (KPIs)), literature review (academic database), PHC-related national documents, consultations with an advisory committee of national experts (6-meetings), and the Delphi technique for finalizing the framework. RESULTS: The Iranian sub-national PHCMF was finalized with 100 KPIs in three components including Health systems determinants, Service Delivery, and Health system objectives. Based on the result chain domain, most KPIs were related to the output (24 KPIs) and the least were related to the input and the process (9 KPIs). CONCLUSION: Regarding the comprehensiveness of the developed measurement framework due to its focus on all PHC operational levers and key aspects of PHC systems' performance, it can be used as a practical tool for assessing and improving the Iranian sub-national PHC system.

Barriers to community participation in primary health care of district health: a qualitative study.

INTRODUCTION: Community participation is one of the principles of primary health care (PHC). However, it has not been adequately institutionalized due to numerous barriers. Therefore, the present study is conducted to identify barriers to community participation in primary health care in the district health network from the perspectives of stakeholders. METHODS: This qualitative case study was conducted in 2021 in Divandareh city, Iran. A total of 23 specialists and experts experienced in community participation, including nine health experts, six community health workers, four community members, and four health directors in primary health care programs, were selected using the purposive sampling method until complete saturation. Data was collected using semi-structured interviews and analyzed simultaneously using qualitative content analysis. RESULTS: After data analysis, 44 codes, 14 sub-themes, and five themes were identified as barriers to community participation in primary health care in the district health network. The themes included community trust in the healthcare system, the status of community participation programs, the community and system's perception of participation programs, health system management approaches, and cultural barriers and institutional obstacles. CONCLUSION: Based on the results of this study most important barriers to community participation relate to community trust, the organizational structure, community and the health profession's perception regarding the participatory programs. It seems necessary to take measures to remove barriers in order to realize community participation in primary healthcare system.

Public-private partnership in primary health care: an experience from Iran.

AIM: The aim of this paper is to introduce the experience of applying public-private partnership (PPP) in providing primary health care (PHC) in East Azerbaijan Province (EAP), Iran. BACKGROUND: Moving toward the Universal Health Coverage (UHC) involves using of all health-related resources. Certainly, one of the key strategies for achieving UHC is PPP. Since 2015, a PPP in PHC policy has begun in EAP as a major strategy for strengthening the health system and achieving UHC. METHODS: In this case study, data were collected through interviews with stakeholders, document analysis, reviewing of health indexes and published studies. The data were analyzed using content analysis. FINDING: PPP in PHC policy was designed and implemented in EAP with the aim of social justice, strengthening the health system and achieving UHC in the framework of health complexes (HCs). HCs provide a defined service package according to the contract. The reimbursement method is a combination of per capita, fee for services and bonus methods. Part of the payments is fixed and the other part is based on the pay for quality system and paid according to the results of monitoring and evaluation. According to the study results, the most important strength of the plan is to improve access to services, especially in marginalized areas. The main weakness is not providing infrastructures before the implementation of the plan, and the most important challenges are financial, political and organizational unsustainability and, sometimes, poor cooperation by the other organizations. The findings show that PPP in PHC in EAP is an effective strategy to provide social justice, implement family practice and achieve UHC.

Effect of salt reduction interventions in lowering blood pressure: A comprehensive systematic review and meta-analysis of controlled clinical trials.

BACKGROUND: Excessive salt intake results in hypertension (HTN), which is a major risk factor for cardiovascular disease (CVD). This review and meta-analysis aimed to evaluate the effect of salt reduction interventions on systolic blood pressure (SBP) and diastolic blood pressure (DBP). METHODS: Studies were identified via systematic searches of the databases, including PubMed, Embase, Scopus, and Web of Science. All the studies examining the effectiveness of salt reduction interventions on blood pressure (BP), regardless of age, sex, and HTN status, were included in the systematic review, and eligible studies were used in the meta-analysis. A random-effect model was applied for quantitative data synthesis. RESULTS: A total of 50 trials extracted from 40 articles (21 trials on nutrition education,10 on self-help materials,17 on salt substitutes, and 2 on food reformulation) were included in the systematic review. The pooled results of 44 eligible trials showed that salt substitution and nutrition education interventions had significant effects on both SBP (WMD: -7.44 mmHg, P<0.001 and WMD: -2.75 mmHg, P<0.001, respectively), and DBP (WMD: -3.77 mmHg, P<0.001 and WMD: -2.11 mmHg, P<0.001, respectively). Furthermore, using self-help materials led to a significant reduction in SBP among subjects aged 25-60 years (WMD: -2.60 mmHg, P = 0.008); it also decreased both SBP and DBP among those who were hypertensive (WMD: -3.87 mmHg, P = 0.003 and WMD: -2.91 mmHg, P<0.001, respectively). CONCLUSION: Our results supported that salt substitution and nutrition education are effective nutrition strategies to lower BP. It seems that multi-component approaches could be more effective in improving BP status. However, further trials are required.

Prioritizing population-based nutrition-related interventions to prevent and control hypertension in Iran: a multi-criteria decision-making approach.

BACKGROUND: Numerous nutrition-related policy options and strategies have been proposed to tackle hypertension and other risk factors of non-communicable diseases (NCDs). In this study, we developed a comparative analysis using a multi-criteria decision-making (MCDM) model for prioritizing population-based nutrition-related interventions to prevent and control hypertension in Iran. METHODS: We employed a combination of Delphi technique and Analytic Hierarchy Process (AHP) method as the methodological tool to prioritize decision alternatives using multiple criteria. The prominent assessment criteria and intervention strategies were derived using a literature review, focus group discussion (n = 11), and a 2-round modified Delphi technique with specialists and experts involved in different stages of health policy-making (round 1: n = 50, round 2: n = 46). Then, the AHP was used to determine the weightage of the selected interventions and develop the decision-making model. The sensitivity analysis was performed to test the stability of the priority ranking. RESULTS: Nine alternative interventions were included in the final ranking based on eight assessment criteria. According to the results, the most priority interventions to prevent and control hypertension included reformulation of food products to contain less salt and changing the target levels of salt in foods and meals, providing low-sodium salt substitutes, and reducing salt intake through the implementation of front-of-package labeling (FOPL). The results of the sensitivity analysis and a comparison analysis suggested that the assessment model performed in this study had an appropriate level of robustness in selecting the best option among the proposed alternatives. CONCLUSION: MCDM techniques offer a potentially valuable approach to rationally structuring the problem, along with the opportunity to make explicit the judgments used as part of the decision-making model. The findings of this study provide a preliminary evidence base to guide future decisions and reforms aiming to improve appropriate population-based interventions for tackling hypertension and other risk factors of NCDs.

The challenges facing programs for the prevention and control of non-communicable diseases in Iran: a qualitative study of senior managers' viewpoints.

BACKGROUND: Despite significant achievements in the prevention and control of NCDs in Iran, these conditions are still the biggest challenges to Iran's healthcare system and are estimated to account for 78.1 percent of all deaths. Therefore, this study aimed to reflect on the potential challenges standing in the way to implement the relevant policies, empower the dimensions of governance, and react in an effective and timely manner by Iran's healthcare system to NCDs. METHODS: This study was conducted with a qualitative approach using the conventional content analysis method. A total of 46 senior managers involved in the prevention and control of NCDs at the medical sciences universities across Iran were recruited through the purposive sampling method and were interviewed via semi-structured interviews. Graneheim and Lundman's approach was utilized to analyze the data. RESULTS: According to the analysis of the senior managers' viewpoints, current challenges to implement the program for the prevention and control of NCDs in Iran could be placed into six main categories, including financing, human resources, infrastructure and inputs, legal, executive, administrative, as well as inter-sectoral collaboration, and management and policy-making challenges with their own sub-categories. CONCLUSION: The results revealed that financing was the biggest challenge to successfully implementing the program for the prevention and control of NCDs in Iran. However, strengthening Iran's healthcare system in the field of the prevention of NCDs demanded more innovative measures and strategies, such as the empowerment of human resources, the effective use of intra- and inter-sectoral collaboration, and non-governmental organizations and charities, along with the exploitation of evidence-based studies during policy-making and decision-making processes, with no need for financial resources.

Developing Iranian sub-national Primary Health Care Measurement Framework: a study protocol.

BACKGROUND: Developing an effective system for measurement and improvement of primary health care (PHC) based on the conditions and characteristics of the countries' health systems is one of the World Health Organization (WHO) recommendations. AIMS: This study will aim to develop a framework to assess the Iranian sub-national PHC system performance using the WHO measurement framework for PHC. METHODS/DESIGNS: This is a mix-method study with a triangulation design. The Iranian sub-national PHC Measurement Framework (PHCMF) will be developed through a review of the WHO's PHC measurement conceptual framework (for selecting key performance indicators (KPIs)), literature review (academic database), PHC-related national documents, consultations with national experts, and the Delphi technique for finalizing the framework. The required data for calculating selected KPIs is expected to encompass qualitative and quantitative data. Discussion: Iranian PHC system performance is not measured based on the holistic and scientific framework and international standards. The information obtained from this project will guide managers and policymakers to be aware of the current situation and the success rate of the PHC system in achieving the desired goals, as well as identify strengths and weaknesses of the PHC system and provide the solution to better policy formulation.

Weight of Risk Factors for Adjusting Capitation in Primary Health Care: A Systematic Review.

Background: Capitation payment is the best-known strategy for paying providers in primary health care. Since health care needs and personal characteristics play an essential role in health care utilization and resource spending, there is a growing tendency on risk adjustment models among health researchers. The objective of this systematic review was to examine the weights used for risk adjustment in primary health care capitation payment. Methods: We systematically searched Scopus, ProQuest, Web of Science, and PubMed in March 2018. Two authors independently apprised the included articles and they also evaluated, identified, and categorized different factors on capitation payments mentioned in the included studies. Results: A total of 742 studies were identified and 12 were included in the systematic review after the screening process. Risk factors for capitation adjustment included age, gender, and income with the weighted average being 1.76 and 1.03, respectively. Moreover, the weighted average disease incidence adjusted clinical groups (ACGs), diagnostic cost groups (DCGs), principal in patient diagnostic cost groups (PIP-DCGs), and hierarchical coexisting conditions (HCCs) were reported as 1.31, 24.7-.99, 10.4-.65, and 11.7-1.01, respectively. Conclusion: In low-income countries, the most effective factors used in capitation adjustment are age and sex. Moreover, the most applied factor in high-income countries is adjusted clinical groups, and income factors can have a better impact on the reduction of costs in low-income countries. Each country can select its most efficient factors based on the weight of the factor, income level, and geographical condition.

Setting research priorities to achieve long-term national road safety goals in Iran.

Background: Road traffic crashes (RTCs) and its associated injuries are one of the most important public health problems in the world. In Iran, RTCs rank second in terms of mortality. To address this issue, there is a need for research-based interventions. Prioritizing researches using a variety of approaches and frameworks to determine the most effective interventions is a key nodal point in the RTCs' research policy planning cycle. Thus, this study aims to generate and prioritize research questions in the field of RTCs in Iran. Methods: By adapting the Child Health and Nutrition Research Initiative (CHNRI) method, this study engaged 25 prominent Iranian academic leaders having role in setting Iran's long-term road safety goals, a group of research funders, and policymakers. The experts' proposed research questions were independently scored on a set of criteria: feasibility, impact on health, impact on the economy, capacity building, and equity. Following the prioritization of Research Questions (RQs), they were all classified using the 5 Pillar frameworks. Results: In total, 145 Research Questions were systematically scored by experts against five criteria. Iran's top 20 road traffic safety priorities were established. The RQs related to "road safety management" and "road and infrastructure" achieved a high frequency. Conclusions: The top 20 research questions in the area of RTCs in Iran were determined by experts. The majority of these RQs were related to "road safety management". The results of this study may contribute to the optimal use of resources in achieving long-term goals in the prevention and control of road traffic crashes and its related injuries. Considering these RQs as research investment options will improve the current status of Road Traffic Injuries (RTIs) at a national level and further advance toward compliance with international goals. If these research priorities are addressed, and their findings are implemented, we can anticipate a significant reduction in the number of crashes, injuries, and deaths.

Countries' experiences in reforming hospital administration structure based on the Parker and Harding model: A systematic review study.

In recent years, many reforms have been made on the structure of hospital administration, most of which are proposed by Parker-Harding models. Therefore, the purpose of this study is to systematically review global relevant experiences in reforming the hospital governance structure with emphasis on the Parker-Harding model. Required information was collected using keywords autonomization, corporatization, privatization, decentralization, reform, hospital autonomy, governance model, and structural reform in databases such as EMBASE, PubMed, Scopus, SID, MagIran, and other resources. Information on the subjects under study was collected from 1990 to 2020. The content extraction method was used for data extraction and data analysis. Thirty-nine sources were included in the study. Results of searching for relevant evidence on a variety of hospital governance models (government, board, corporate, and private) based on the Parker-Harding model in four categories including strengths (31), weaknesses (30), outcomes (26), and interventions (21) are outlined. In this study, strengths, weaknesses, outcomes, and corrective interventions were presented for different models of hospital administration that could be used by healthcare policymakers. Also, According to the results of this study, governmental model less recommended.

Nationwide population-based surveys of Iranian COVID-19 Serological Surveillance (ICS) program: The surveys protocol.

Background: Serological surveillance of COVID-19 through conducting repetitive population-based surveys can be useful in estimating and monitoring changes in the prevalence of infection across the country. This paper presents the protocol of nationwide population-based surveys of the Iranian COVID-19 Serological Surveillance (ICS) program. Methods: The target population of the surveys is all individuals ≥6 years in Iran. Stratified random sampling will be used to select participants from those registered in the primary health care electronic record systems in Iran. The strata are the 31 provinces of the country, in which sampling will be done through simple random sampling. The sample size is estimated 858 individuals for each province (except for Tehran province, which is 2574) at the first survey. It will be recalculated for the next surveys based on the findings of the first survey. The participants will be invited by the community health workers to the safe blood sampling centers at the district level. After obtaining written informed consent, 10 mL of venous blood will be taken from the participants. The blood samples will be transferred to selected reference laboratories in order to test IgG and IgM antibodies against COVID-19 using an Iranian SARS-CoV-2 ELISA Kit (Pishtaz Teb). A serologically positive test is defined as a positive IgG, IgM, or both. After adjusting for the measurement error of the laboratory test, nonresponse bias, and sampling design, the prevalence of COVID-19 will be estimated at the provincial and national levels. Also, the approximate incidence rate of infection will be calculated based on the data of both consecutive surveys. Conclusion: The implementation of these surveys will provide a comprehensive and clear picture of the magnitude of COVID-19 infection and its trend over time for health policymakers at the national and subnational levels.

Prevalence of COVID-19 in Iran: results of the first survey of the Iranian COVID-19 Serological Surveillance programme.

OBJECTIVES: This study aims to estimate the prevalence of coronavirus disease 2019 (COVID-19) in the general population of Iran. METHODS: The target population was all Iranian people aged 6 years and older in the country. A stratified random sampling design was used to select 28 314 people from among the individuals registered in the electronic health record systems used in primary health care in Iran. Venous blood was taken from each participant and tested for the IgG antibody against COVID-19. The prevalence of COVID-19 was estimated at provincial and national levels after adjusting for the measurement error of the laboratory test, non-response bias and sampling design. RESULTS: Of the 28 314 Iranians selected, 11 256 (39.75%) participated in the study. Of these, 5406 (48.0%) were male and 6851 (60.9%) lived in urban areas. The mean (standard deviation) participant age was 35.89 (18.61) years. The adjusted prevalence of COVID-19 until 20 August 2020 was estimated as 14.2% (95% uncertainty interval 13.3%-15.2%), which was equal to 11 958 346 (95% CI 11 211 011-12 746 776) individuals. The adjusted prevalences of infection were 14.6%, 13.8%, 16.6%, 11.7% and 19.4% among men, women, urban population, rural population and individuals aged 60 years or more, respectively. Ardabil, Golestan and Khuzestan provinces had the highest prevalence and Alborz, Hormozgan and Kerman provinces had the lowest. CONCLUSIONS: Based on the study results, a large proportion of the Iranian population had not yet been infected by COVID-19. The observance of hygienic principles and social restrictions should therefore continue until the majority of the population has been vaccinated.

Clinical outcomes of patients with mild COVID-19 following treatment with hydroxychloroquine in an outpatient setting.

The role of hydroxychloroquine (HCQ) in early outpatient management of mild coronavirus disease 2019 (COVID-19) needs further investigation. This study was a multicenter, population-based national retrospective-cohort investigation of 28,759 adults with mild COVID-19 seen at the network of Comprehensive Healthcare Centers (CHC) between March and September 2020 throughout Iran. The baseline characteristics and outcome variables were extracted from the national integrated health system database. A total of 7295 (25.37%) patients who presented with mild COVID-19 within 3-7 days of symptoms onset received HCQ (400 mg twice daily on day 1 followed by 200 mg twice daily for the next four days and were then followed for 14 days). The main outcome measures were hospitalization or death for six months follow-up. COVID-19-related hospitalizations or deaths occurred in 523 (7.17%) and 27 (0.37%) respectively, in HCQ recipients and 2382 (11.10%) and 287 (1.34%) respectively, in non-recipients. The odds of hospitalization or death was reduced by 38% (odds ratio [OR] = 0.62; 95% confidence interval [CI]: 0.56-0.68, p = < 0.001) and 73% (OR = 0.27; 95% CI: 0.18-0.41, p = < 0.001) in HCQ recipients and non-recipients. These effects were maintained after adjusting for age, comorbidities, and diagnostic modality. No serious HCQ-related adverse drug reactions were reported. In our large outpatient national cohort of adults with mild COVID-19 disease who were given HCQ early in the course of the disease, the odds of hospitalization or death was reduced significantly regardless of age or comorbidities.
