Financial protection before and after Indonesia's national health insurance scheme - a repeated cross-section study","authors":"Gindo Tampubolon","doi":"10.1101/2024.03.05.24303817","DOIUrl":"https://doi.org/10.1101/2024.03.05.24303817","url":null,"abstract":"The world is ageing with unprecedented momentum, and large global south nations are ageing at higher speed than their northern peers. They have grown old while they have not grown rich, straining their health systems' ability to deliver financial protection. This work aimed to assess whether Indonesia's health insurance scheme, seven years on, has delivered equal protection for families with older members (over 60 years) as for other families. Methods\u0000Before-and-after observation study is designed to estimate how much difference the Scheme made to probabilities of catastrophic payment and financial impoverishment for the two family types. As in recent assessments, two national socioeconomic surveys were used (2013, 2021). Two level observations came from 622,125 families residing in 514 districts across the archipelago. Financial protection indicators against catastrophic payment and impoverishment were constructed following recent works. I estimated two level probit models, then plotted marginal probabilities of financial protection. A sensitivity analysis was conducted with the standard financial protection indicator. Findings\u0000After the Scheme, financial hardship for all family types has reduced by 19%. But families with older members (compared to other families) have an additional 0.7% risk of incurring catastrophic payment or financial impoverishment. And social and spatial inequalities in health persist. Discussion\u0000While the Scheme has markedly improved financial protection for all, families with older members remain at higher risk of being unprotected. The global south can prepare for an ageing world by monitoring financial protection and its social determinants and systematically distinguishing families with older members.","PeriodicalId":501386,"journal":{"name":"medRxiv - Health Policy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140057641","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}

Respondents expressed that authentic HD/E research investigates disparities/inequalities in health outcomes or access to healthcare services that are specific to communities defined by a social or demographic characteristic. Challenges included lack of funding, a slow rate of recruiting minority populations, and an under-valuation of HD/E research among funders and scientific journals. Indicators of good quality HD/E research were community involvement and a social justice context. Respondents also expressed concerns that poor quality HD/E research could inadvertently harm minoritized communities.

{"title":"The importance of mothers: The social transmission of COVID-19 vaccination attitudes and uptake","authors":"Oscar Thompson, Mioara Cristea, Monica Tamariz","doi":"10.1101/2024.03.06.24303875","DOIUrl":"https://doi.org/10.1101/2024.03.06.24303875","url":null,"abstract":"The global fight against the COVID-19 pandemic has underscored the critical importance of widespread vaccination to mitigate the impact of the virus on public health. The current study aimed to investigate which social influences might be most important for predicting attitudes towards COVID-19 vaccination and vaccine uptake among young students in the UK. We focused on the cultural evolution and social transmission aspects, i.e., parent-to-child versus peer-to-peer, of attitudes and vaccine uptake during the COVID-19 pandemic. A sample of 192 UK students (aged 18 to 35 years old) filled in an online survey including measures for attitudes towards COVID-19 vaccination and vaccine uptake and/or intention, age, and gender. Participants were also asked about their mother’s, father’s, and best friend’s attitudes towards COVID-19 vaccination and vaccine uptake. Finally, they provided a subjective measure of the quality relationship with their parents. Overall, our results suggest that both parents and very close friends are important agents in understanding the students’ attitudes towards COVID-19 vaccination and vaccine uptake. More specifically, our findings suggest the mother’s vaccine uptake as the most salient predictor of students’ attitudes towards COVID-19 vaccination and vaccine uptake, particularly when the students disclose having a positive relationship with their parents. In cases where students’ experience negative relationship with their parents, the best friend’s vaccine uptake may supersede the mother’s influence. Despite these nuances, a general trend emerges from our data suggesting that vaccine uptake could be primarily guided by vertical transmission (i.e., parent to child). Our results have the potential to influence public health strategies, communication campaigns, and targeted interventions to enhance vaccination uptake. Identifying key social predictors can enable policymakers and health authorities to tailor vaccination promotion efforts towards mothers’ and peers’ vaccine uptake to increase overall positive attitudes and vaccine uptake among young people.","PeriodicalId":501386,"journal":{"name":"medRxiv - Health Policy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140054386","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}

While approximately 6,700 public comments were submitted during the open comment period, there is not a reliable mechanism to quantify how clinical laboratorians as a sector perceive the proposed rule. To solicit quantifiable feedback on the FDA's proposed rule, a ten-item questionnaire was developed and submitted to clinical laboratory customers of ARUP Laboratories, a national nonprofit clinical laboratory of the University of Utah Department of Pathology. Of 503 clinical laboratory respondents, only 41 (8.2%) support the FDA's proposed rule. 66.9% of respondents work in laboratories that perform LDTs and were therefore asked additional questions regarding the proposed rule. 83.9% of these respondents believe that the proposed rule will negatively impact their laboratories, while only 3.0% believe that they have the financial resources to pay for FDA user fees. 60.9% of respondents anticipate removing tests from their laboratory menus if the proposed rule is enacted, while an additional 33.2% indicated that they do not yet know. Only 11.2% of respondents believe that they would pursue FDA submissions for all of their existing LDTs if the final rule is enacted. The vast majority of respondents (>80%) were either 'extremely concerned' or 'very concerned' about the impact of the proposed rule on patient access to essential testing, financial and personnel resources to comply, innovation, the FDA's ability to implement the proposed rule, and send-out costs and test prices. Respondents indicated that they would rely heavily on reference laboratory partners for advocacy against the proposed rule, testing options, education, and consultation if the rule was enacted. Thematic analysis of open comments revealed strong opposition to the proposed rule and significant concern regarding negative impacts to patient care across clinical laboratory settings.","PeriodicalId":501386,"journal":{"name":"medRxiv - Health Policy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140011434","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}

Hence, this study investigates the university students perceptions toward using AI in healthcare. A cross-sectional survey was conducted at two major universities using a paper-based questionnaire from September 2023 to November 2023. Participants' views regarding using artificial intelligence in healthcare were investigated using 25 items distributed across five domains. The Mann-Whitney U test was applied for the comparison of variables. The response rate for the survey was 75%, with a sample size of 279. More than half of the participants (52%, n = 145) expressed their belief in AI's potential to reduce treatment errors in the future. However, about (61.6%, n = 172) of participants fear the influence of AI that could prevent doctors from learning to make correct patient care judgments, and it was widely agreed (69%) that doctors should ultimately maintain final control over patient care. Participants with experience with AI, such as engaging with AI chatbots, significantly reported higher scores in both the \"Benefits and Positivity Toward AI in Healthcare\" and \"Concerns and Fears\" domains (p = 0.024) and (p = 0.026), respectively. The identified cautious optimism, concerns, and fears highlight the delicate balance required for successful AI integration. The findings emphasize the importance of addressing specific concerns, promoting positive experiences with AI, and establishing transparent communication channels. Insights from such research can guide the development of ethical frameworks, policies, and targeted interventions, fostering a harmonious integration of AI into the healthcare landscape in developing countries.","PeriodicalId":501386,"journal":{"name":"medRxiv - Health Policy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140011210","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}

Through the International Classification of Diseases, Tenth Revision Code (ICD-10), documentation of NIHSS scores has been made possible for administrative purposes and has since been increasingly adopted in insurance claims. Per CMS guidelines, the stroke ICD-10 diagnosis code must be documented by the treating physician, but ICD-10 NIHSS scores can be documented by any healthcare provider involved in the patient's care. Accuracy of the administratively collected NIHSS compared to expert clinical evaluation as documented in the Paul Coverdell registry is however still uncertain.\u0000Methods: Leveraging a linked dataset comprised of the Paul Coverdell National Acute Stroke Program (PCNASP) clinical registry and probabilistically matched individuals on Medicare Claims data, we sampled patients aged 65 and above admitted for AIS across nine states, from 2016 to 2019. We excluded those lacking documentation for either clinical or ICD-10 based NIHSS scores. We then examined score concordance from both databases and measured discordance as the absolute difference between the PCNASP and ICD-10-based NIHSS scores. Results: Among 66,837 matched patients, mean NIHSS scores for PCNASP and Medicare ICD-10 were 7.26 (95% CI: 7.20 - 7.32) and 7.40 (95% CI: 7.34 - 7.46), respectively.
