The literature on immigrants' “bureaucratic incorporation”—that is, the degree of institutional responsiveness to immigrant newcomers in new destinations— suggests that federal policy may make the ER relatively welcoming. However, based on interviews conducted between July 2018 and July 2023 with 17 Latinx immigrant women, 15 clinic staff, 13 area officials, a media review, and bureaucratic accompaniment of immigrants seeking care and financial assistance, I show that the hospital engaged in a suite of “strategies of containment” to distance immigrants from its ER: it attempted to confine immigrants to a “Latino clinic,” charged them up-front for care, diverted them to Denver, and excluded the undocumented from charity care. I argue that in a financialized landscape of frequent hospital consolidations and mergers, hospital officials viewed Latinx immigrants as portending uncompensated care that could jeopardize their independence and compromise their resort brand. By examining the responses of a resort hospital in a racially homogeneous new destination to the perceived “influx” of Latinx immigrant outsiders, the parallel between hospital practices and strategies of containment become clear. This article suggests the relevance of the literature on the spatialization of immigration enforcement to analyses of how hospitals evade their obligations to provide emergency care—whether through externalization, deterrence, or diversion.</div></div>","PeriodicalId":49122,"journal":{"name":"Social Science & Medicine","volume":"371 ","pages":"Article 117863"},"PeriodicalIF":4.9,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we identify and describe three distinct types of uncertainty that obstetrician-gynecologists (OB-GYNs) in states with abortion bans encounter when caring for patients with an obstetric complication known as preterm prelabor (or premature) rupture of membranes (PPROM, i.e., ‘water breaking’). PPROM represents a paradigmatic case in which prognostic, legal, and existential uncertainty coalesce, leading to stress and discomfort for both patients and the clinicians caring for them. Focusing on OB-GYNs, we describe each of these forms of medical uncertainty in turn, and then elaborate a case study to show how they operate in tandem over time. In doing so, we add to a growing body of literature highlighting the relationship between structural conditions shaping medicine and uncertainty in practice. Whereas evidence-based medicine is organized around the logic of reducing uncertainty, we find that doing so is far more difficult when the uncertainty arises from politics as opposed to clinical factors.</div></div>","PeriodicalId":49122,"journal":{"name":"Social Science & Medicine","volume":"369 ","pages":"Article 117856"},"PeriodicalIF":4.9,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing an experimental design (<em>N</em> = 354) with pre- and post-measurements of suicidal thoughts, the findings revealed that exposure to social media posts on hope, healing, and recovery by an influencer with lived experience of a suicide attempt elicited a significant reduction in suicidal thoughts in a convenience sample of the general population.

Social media posts on hope, healing, and recovery also increased the intention to seek help when experiencing suicidal thoughts.

However, evidence from within health economics suggests that <em>how</em> outcomes are achieved matters as well as <em>what</em> outcomes are achieved, reflecting a concern for process utility. This issue has received much less attention in public health perhaps because of the greater complexity. For example, upstream, non-health policies affect both health and non-health outcomes and policy characteristics, such as universality versus targeting, can generate much debate. In this mixed-method exploratory preference-based study we examined whether and why 50 members of the general public from across Glasgow and Newcastle traded-off the policy characteristics and health and non-health outcomes of a Universal Basic Income and a Minimum Income Guarantee using Benefit Trade-Off and qualitative questions in one-to-one face-to-face interviews. For a majority of respondents, choices were driven by outcomes over policies characteristics, although for a substantial minority it was policy characteristics and not outcomes that influenced preferences. Qualitative data provide support for the different choices. As respondents trade-off policy characteristics and policy outcomes reflecting different preferences for each, studies looking at either in isolation may under- and over-state preferences. Similarly, failure to account for process utility in policymaking may result not only in the misallocation of resources but a lack of social acceptability, which could jeopardise the chances of a policy being implemented in the first place.</div></div>","PeriodicalId":49122,"journal":{"name":"Social Science & Medicine","volume":"370 ","pages":"Article 117855"},"PeriodicalIF":4.9,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143511312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
