Another discussed idea during the pandemic, though it attracted less attention, was about patients' right to learn about the vaccination status of their health‐care providers. In this paper, we examined public attitudes toward these two rights using data from a cross‐sectional survey conducted in South Dakota in the summer of 2021. We utilized registration‐based sampling to recruit participants. The survey collected data on some of the most significant variables reported in the literature that shape people's attitudes toward COVID‐19 vaccines. Specifically, participants provided information on their age, gender, educational level, household income, COVID‐19 vaccination status, stress induced by the pandemic, and political partisan identification. The health‐care providers' rights as well as the patients' rights were gauged with one item each using a five‐point Likert scale. We analyzed data from 573 respondents (<jats:italic>M</jats:italic><jats:sub>age</jats:sub> = 56.6 years, SD = 16.48), which showed that older participants, those with higher levels of COVID‐19‐related stress, and vaccinated individuals expressed higher support, while Republicans expressed lower support for the two policies. Gender, education, and income did not influence participants' attitudes. Although the findings might have limited generalizability to populations outside South Dakota, they offer valuable insights for developing comprehensive ethical codes where vaccination status might be at the center stage for clinician‐patient relationships in future pandemic responses.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"48 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140615717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, implementation problems often make it difficult for these initiatives to contribute to people's well-being. The objective of the present study is to describe a strategy for implementing the components of global mental health in two complex Colombian territories: Chocó and La Guajira. These components are a primary health-care approach, continuity of care, anti-stigma, mental health as a human right, mental health in all policies, and a community model of recovery. A monitoring system was created for the reporting of these components by each territory. An appropriation of all the components by the health systems of both territories was found, as mobilization of existing technical resources in the territories and the strengthening of capacities at the administrative, clinical, and community levels, in addition to the articulation of all the strategies proposed at the level global for recovery. Innovation processes built in a participatory manner with communities can favor the implementation of evidence-based practices and public policies in mental health in territories where social determinants make recovery a challenge.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"20 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140601910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is argued that two main factors comprise this threat: significant safety concerns over many traditional herbal preparations, and a conflict in therapeutic frameworks which provides a substrate for the production of misinformation regarding allopathic medicine. Poorly enforced regulation of the commercial herbal market and a total lack of regulation of the traditional herbal market have led to prevalent contamination of herbal preparations with pathogenic bacteria and an unacceptable risk of pharmacological toxicity due to inconsistent production methods and understanding of the active components in these preparations. Simultaneously, misinformation spread by traditional herbal practitioners about allopathic medicine has caused significant morbidity and mortality in Ghana. Evidence from the literature and experience from clinical practice in a hospital in the Eastern region of Ghana are used to explore these factors and provide recommendations. First, thorough regulation of the herbal practice is needed to allay safety concerns. Second, the overall healthcare landscape will have to change to resolve the current tensions between practices. One solution would be the formation of a cooperative healthcare system which incorporates both the allopathic and herbal practices with well‐defined, nonoverlapping scopes of practice. However, such a novel landscape may be unrealistic, with the potential for traditional herbal practices being relegated to secondary role, mainly providing pharmacologically inert preparations while continuing to benefit patients through spiritual, cultural and pastoral interventions.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"20 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140601715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We know less about whether this conflict still carries over to the broader public. Moreover, we know little about the degree to which the conflict reaches into its various policies and whether the policy threats to the ACA can affect public opinion. We fielded a large, and demographically diverse survey of US adults using Lucid (<jats:italic>N</jats:italic> = 6066) from July 8–21, 2020. The survey contained an experiment that introduced the topic to respondents as the 2010 health reform law, the ACA, or Obamacare and at times highlighted the potential undoing of the ACA by the US Supreme Court. Analyses were conducted using Ordinary Least Squares regression. Our findings indicate that perceptions of the ACA differ substantial based on partisanship and racial prejudice. Framing still matters in the minds of Americans and their perception of health reforms in general and its individual components by extending these differences. However, we find only very limited evidence for changes to public attitudes related to the policy threat of the Supreme Court ruling the ACA constitutional in California v. Texas. The ACA remains a political battleground in the minds of Americans. The politics of the ACA continue to be shaped by perceptions of race and partisanship.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"35 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140601798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we draw on interdisciplinary research on manufactured controversies in science‐policy deliberation to argue that the development of meaningful COI policy has been stymied through argumentative “wedges” designed to delay consensus and policy formation. Argumentative wedges disrupt policy formation by mischaracterizing the evidence base, continuously redefining the terms of the debate and/or recommending overly narrow criteria for who should be allowed to participate in policy deliberation. In this article, we argue researchers and policymakers interested in better addressing the harmful effects of COI can improve their efforts through strategic efforts designed to disrupt the wedges of manufactured controversy. Additionally, we argue that efforts to address COI can be further enhanced through embracing a broader framework for COI inquiry. Specifically, we argue that aggregate approaches to COI can help to disrupt these wedges and provide a strong foundation for future policy.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"70 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140601707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average long‐term value of morbidity coefficients among the studied medical workers was 995.9 ± 9.9 cases per 1000 people over 7 years. The analysis of the structure of diseases was carried out based on information obtained from sick leave records of the study group of dentists for the period from 2015 to 2022. The dental profession has its own characteristics; the unfavorable factors identified during the study can be divided into three groups: factors related to the treatment process; factors related to the organization of premises in dental clinics; factors related to insufficient ergonomics of dental equipment and instruments; and the quality of filling and dental materials. Six of the same classes of diseases play a leading role in the structure of diseases identified during medical examinations, but their significance is different: in the first place are diseases associated with increased psychological stress (circulatory disorders, psychoneuroses, diseases of the digestive system), diseases associated with forced working position (musculoskeletal diseases).","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"105 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140601784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall, 19% of listed providers in 2018 and 8% of listed providers in 2019 showed inaccuracies. However, we found substantial differences across markets, with a low of 54% accuracy for Medicaid listings in 2018. Commercial plans were consistently most accurate. In terms of adequacy, we found that more than 90% of listed providers were accessible within 15 days and 97% within 30 days, with Medicaid providing the highest rates of timely access. Overall, barriers to consumer access with regard to physical therapy appear to be primarily in the form of provider directory inaccuracies. High rates of inaccuracies raise concerns for patients as well as regulators.

Improving food security in slow-onset disasters requires policy development by both regional and national governments. Despite this articulated need, very little research on the national and regional food security policies in slow-onset disaster events has been undertaken. Focusing on Southeast Asia, this paper aims to (i) review existing policies to support food security in slow-onset disasters; (ii) identify strengths, weaknesses, and gaps in the existing policies; (iii) explain the policy window on food security in slow-onset disasters. An analytical framework of eight components of food security was adopted for the content analysis of 39 related policy documents collected from 11 countries in Southeast Asia and the Association of Southeast Asian Nations. The study found that none of the 39 policies directly targeted improving food security in slow-onset disasters. Existing policies to support food security in slow-onset disasters were incorporated in the context of climate change or national target programs on green development, agricultural development, nutrition, and famine. Our analysis also revealed that existing policies primarily focus on the first two pillars of the food security framework: food availability and access, with a predominant emphasis on availability. However, the third pillar, food utilization, is often overlooked. This study recommends developing a comprehensive policy to address protracted food insecurity, particularly among vulnerable populations in areas impacted by slow-onset disasters.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"222 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139678469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is to assess its effects on key indicators in the health insurance sector, including gross written premiums (GWPs), insurance penetration, gross claims paid by health insurance, and insurance density. Quantitative data from official sources, including the Saudi Central Bank and the Council of Health Insurance (CHI), were analyzed. A two-sample <i>t</i>-test was employed to compare pre implementation (2014–2017) and post implementation (2019–2022) periods for selected indicators. The study found a significant increase in GWPs, suggesting heightened revenue generation for insurers, likely due to increased demand, adjusted pricing strategies, and expanded coverage. Insurance penetration notably widened, indicating improved accessibility, driven by awareness campaigns and subsidies. Gross claims paid by health insurance increased significantly, showing insurers disbursing more funds to cover healthcare costs. However, there was no significant impact on insurance density, highlighting the need for additional strategies to extend coverage. Saudi Arabia's updated Unified Health Insurance Policy has yielded transformative effects, enhancing accessibility and affordability. It has increased revenue generation, improved insurance penetration, and raised the amount paid by insurers to cover healthcare costs. The policy's impact on insurance density is limited, necessitating further efforts to extend coverage. These findings have significant policy implications, urging policymakers to refine healthcare policies and insurers to adapt to new revenue prospects, promising better overall health outcomes for the population. Further comprehensive research is essential to validate these conclusions and explore broader policy impacts.","PeriodicalId":44943,"journal":{"name":"World Medical & Health Policy","volume":"18 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139678466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
