Dementia specialists – neurologists, geriatricians, and geriatric psychiatrists – serve a critical clinical function in diagnosing early-stage Alzheimer’s disease and determining eligibility for treatment with disease-modifying therapies. However, the availability of dementia specialists is limited and varies across the U.S. Using data from the Area Health Resources Files, we found that the median density of dementia specialists across hospital referral regions in U.S. is 29.7 per 100,000 population aged 65 and older (interquartile range 20.7 to 44.0). We derived thresholds of 33 to 45 dementia specialists per 100,000 population aged 65 and older as the provider density necessary to care for older adults with mild cognitive impairment and dementia. Based on these thresholds, we estimated that 34% to 60% of the population aged 65 and older resided in areas with potential dementia specialist shortfalls. The extent of potential shortfalls varied by state and rurality. A better understanding of potential gaps in the availability of dementia specialists will inform policies and practices to ensure access to services for people with cognitive impairment and dementia.
痴呆症专科医生--神经科医生、老年病学家和老年精神病学家--在诊断早期阿尔茨海默病和确定是否有资格接受疾病改变疗法治疗方面发挥着重要的临床作用。利用地区卫生资源档案的数据,我们发现美国各医院转诊地区痴呆症专科医生的密度中位数为每 10 万名 65 岁及以上人口中有 29.7 名痴呆症专科医生(四分位数间距为 20.7 到 44.0)。我们将每 10 万名 65 岁及以上人口中 33 至 45 名痴呆症专科医生作为护理患有轻度认知障碍和痴呆症的老年人所需的医疗机构密度阈值。根据这些阈值,我们估计有 34% 至 60% 的 65 岁及以上人口居住在痴呆症专科医生可能短缺的地区。潜在缺口的程度因州和地区而异。更好地了解痴呆症专家供应方面的潜在缺口,将为确保认知障碍和痴呆症患者获得服务的政策和实践提供依据。

Biosimilar underutilization alone does not foretell a broken biologics market 生物仿制药利用不足本身并不预示着生物制剂市场的崩溃

Biosimilars offer the potential for cost savings and expanded access to biologic products, however, there are concerns regarding the rate of biosimilar uptake. We assessed the relationship between biosimilar and originator pricing, coverage, and market share by describing four case studies that fall into two categories: (1) sole preferred coverage strategy (i.e., aim is to have originator product preferred; biosimilar(s) non-preferred), defined as steep ASP reductions for originator products (decline in net prices by at least 50% following the introduction of biosimilar competition by 2022) and (2) non-sole preferred coverage strategy (i.e., aim is to have originator product preferred alongside biosimilar products), defined as moderate ASP reductions for originator products with (net prices did not decline by at least 50% of its pre-biosimilar competition value). We found that originators with sole preferred coverage strategies maintained formulary preference and market share relative to originators with non-sole preferred coverage strategies. Regardless of strategy, the market-weighted ASP for all four product families (originator and biosimilars) declined significantly in the years following the introduction of biosimilars, suggesting that biosimilar uptake alone may not be a complete measure of whether the biosimilar market is facilitating competition and lowering prices.
生物仿制药具有节约成本和扩大生物制品使用范围的潜力,但人们对生物仿制药的吸收率存在担忧。我们评估了生物仿制药与原研药定价、覆盖范围和市场份额之间的关系,并将四个案例研究分为两类:(1) 唯一优先覆盖战略(即目标是原研药产品优先;生物仿制药非优先),定义为原研药产品的 ASP 锐减(到 2022 年引入生物仿制药竞争后,净价格下降至少 50%);(2) 非唯一优先覆盖战略(即目标是原研药产品与生物仿制药同时优先),定义为原研药产品的 ASP 锐减(到 2022 年引入生物仿制药竞争后,净价格下降至少 50%)、(2) 非独家优先覆盖战略(即,旨在使原研产品与生物类似药产品同时获得优先覆盖),定义为原研产品的 ASP 降幅适中(净价格至少没有下降到生物类似药竞争前价值的 50%)。我们发现,与采用非独家优先覆盖策略的原研药相比,采用独家优先覆盖策略的原研药能保持处方集优先权和市场份额。无论采用哪种策略,所有四个产品系列(原研药和生物仿制药)的市场加权平均售价在生物仿制药推出后的几年中都出现了显著下降,这表明仅凭生物仿制药的吸收量可能无法全面衡量生物仿制药市场是否促进了竞争并降低了价格。

Regional variation in healthcare use threatens efficient and equitable resource allocation. Within the Medicare program, variation in care delivery may differ between centrally administered traditional Medicare (TM) and privately managed Medicare Advantage (MA) plans which rely on different strategies to control care utilization. As MA enrollment grows, it is particularly important for program design and long-term healthcare equity to understand regional variation between TM and MA plans. This study examined regional variation in length of stay (LOS) for stroke inpatient rehabilitation between TM and MA plans in 2019 and how that changed in 2020, the first year of the COVID-19 pandemic. Results showed that MA plans had larger across-region variations than TM (standard deviation (SD)=0.26 vs. 0.24 days, 11% relative difference). In 2020, across-region variation for MA further enlarged but the trend for TM stayed relatively stable. Market competition among all inpatient rehabilitation facilities (IRFs) within a region was associated with a moderate increase in within-region variation of LOS (elasticity=0.46). Policies reducing administrative variation across MA plans or increasing regional market competition among IRFs can mitigate regional variation in healthcare use.
医疗保健使用方面的地区差异威胁着高效、公平的资源分配。在医疗保险计划中,中央管理的传统医疗保险(TM)和私人管理的医疗保险优势计划(MA)在提供医疗服务方面可能存在差异,后者依靠不同的策略来控制医疗服务的使用。随着医疗保险注册人数的增加,了解传统医疗保险和医疗保险计划之间的地区差异对于计划设计和长期医疗保健公平性尤为重要。本研究考察了 2019 年 TM 计划和 MA 计划在中风住院康复的住院时间(LOS)方面的地区差异,以及在 2020 年(COVID-19 大流行的第一年)这一差异的变化情况。结果显示,MA 计划的跨地区差异大于 TM 计划(标准差 (SD)=0.26 对 0.24 天,相对差异为 11%)。2020 年,医疗保险的跨地区差异进一步扩大,但医疗保险的趋势保持相对稳定。区域内所有住院康复设施(IRF)之间的市场竞争与 LOS 区域内差异的适度增加有关(弹性=0.46)。减少医疗保险计划之间的管理差异或增加地区内住院康复设施之间的市场竞争的政策可以缓解医疗保健使用的地区差异。

Value-Based Care (VBC) payment models are becoming increasingly prevalent as alternatives to the traditional fee-for-service paradigm. This research quantifies the relationship between physician characteristics and participation in VBC payment models using the Association of American Medical Colleges’ 2022 National Sample Survey of Physicians. We specified logistic regressions using physician-level variables to assess associations with current and new participation in Accountable Care Organizations, Primary Care First (PCF) model, capitation, and bundled payments. Our results indicate that most respondents engaged in at least one VBC. Participation varied based on several characteristics, and physician specialty was highly predictive of overall participation. Compared to primary care physicians (PCPs), hospital-based physicians (OR=0.6, p<0.001), medical specialists (OR=0.5, p<0.001), psychiatrists (OR=0.4, p<0.001), and surgeons (OR=0.5, p<0.001) were less likely to participate in VBC models. Medical specialists and surgeons were less likely to participate in commercial capitation than PCPs while medical specialists and obstetricians/gynecologists were more likely to participate in certain bundles than PCPs. We suggest several policies to close the cross-specialty participation gap by including specialists and appealing to providers and patients.
作为传统收费服务模式的替代方案,基于价值的医疗(VBC)支付模式正变得越来越普遍。本研究利用美国医学院协会的 2022 年全国医生抽样调查,量化了医生特征与参与 VBC 付费模式之间的关系。我们利用医生层面的变量进行了逻辑回归,以评估当前和新参与责任医疗组织、初级医疗优先(PCF)模式、按人头付费和捆绑式付费的相关性。我们的结果表明,大多数受访者至少参与了一项自愿性医疗保险。参与情况因若干特征而异,医生专业对总体参与情况具有很高的预测性。与初级保健医生 (PCP) 相比,医院内科医生(OR=0.6,p<0.001)、医学专家(OR=0.5,p<0.001)、精神科医生(OR=0.4,p<0.001)和外科医生(OR=0.5,p<0.001)参与 VBC 模式的可能性较低。与初级保健医生相比,内科专家和外科医生参与商业按人头付费的可能性较低,而与初级保健医生相比,内科专家和妇产科医生参与某些捆绑服务的可能性较高。我们建议采取几项政策,通过纳入专科医生并吸引医疗服务提供者和患者来缩小跨专科参与的差距。

Enrollment in Medicare Advantage (MA) has been rapidly growing. We examine whether MA enrollment affects the outcomes of post-acute nursing home care among patients with Alzheimer’s Disease and Related Dementias (ADRD). We exploit year-to-year changes in MA penetration rates within counties from 2012 through 2019. After adjusting for patient-level characteristics and county fixed effects, we find that MA enrollment was not associated with days spent at home, nursing home days, likelihood of becoming a long-stay resident, hospital days, hospital readmission, or 1-year mortality. There was a modest increase in successful discharge to community by 0.73 percentage points (relative increase of 2.4%) associated with a 10-percentage point increase in MA enrollment. The results are consistent among racial/ethnic subgroups and dual-eligible patients. These findings suggest an imperative need to monitor and improve quality of managed care among enrollees with ADRD.
医疗保险优势计划(MA)的参保人数一直在快速增长。我们研究了加入医疗保险是否会影响阿尔茨海默病及相关痴呆症(ADRD)患者的急性期后疗养院护理结果。我们利用了 2012 年至 2019 年期间县内医疗保险渗透率的逐年变化。在对患者水平特征和县固定效应进行调整后,我们发现,医疗保险的加入与在家天数、疗养院天数、成为长期住院患者的可能性、住院天数、再次入院或 1 年死亡率无关。加入医保的人数每增加 10 个百分点,成功出院返回社区的人数就会略微增加 0.73 个百分点(相对增加 2.4%)。种族/民族亚群和双重资格患者的结果一致。这些研究结果表明,有必要对患有 ADRD 的参保者的管理性医疗质量进行监控和改善。

Changes chronic noncancer pain treatment have led to decreases in prescribing of opioids and increases in the availability of medical cannabis, despite its federal prohibition. Patients may face barriers to establishing new care with a physician based on use of these treatments. We compared physician willingness to accept patients based on prescription opioid, cannabis, or other pain treatment use. This study of 36 states and DC with active medical cannabis programs surveyed physicians who treat patients with chronic noncancer pain between July 13 and August 4, 2023. Of 1,000 physician respondents (34.5% female, 63.2% white, 78.1% primary care), 852 reported accepting new patients with chronic pain. Among those accepting new patients with chronic pain, more physicians reported that they would not accept new patients taking prescription opioids (20.0%) or cannabis (12.7%) than non-opioid prescription analgesics (0.1%). In contrast, 68.1% reported willingness to accept new patients using prescribed opioids on a daily basis. For cannabis, physicians were more likely to accept new patients accessing cannabis through medical programs (81.6%) than from other sources (60.2%). Access to care for persons with chronic noncancer pain appears the most restricted among those taking prescription opioids, though patients taking cannabis may also encounter reduced access.
慢性非癌症疼痛治疗的变化导致阿片类药物处方的减少和医用大麻供应的增加,尽管联邦禁止使用医用大麻。患者可能会因为使用这些治疗方法而在与医生建立新的治疗关系时面临障碍。我们根据阿片类处方、大麻或其他疼痛治疗方法的使用情况,比较了医生接受患者的意愿。本研究对 36 个州和特区的现行医用大麻计划进行了调查,调查对象是在 2023 年 7 月 13 日至 8 月 4 日期间治疗慢性非癌症疼痛患者的医生。在 1,000 名受访医生(34.5% 为女性,63.2% 为白人,78.1% 为初级保健医生)中,852 人表示接受了新的慢性疼痛患者。在接受新的慢性疼痛患者的医生中,表示不接受服用处方阿片类药物(20.0%)或大麻(12.7%)的新患者的医生多于不接受服用非阿片类处方止痛药(0.1%)的医生。相比之下,68.1%的医生表示愿意接受每天服用阿片类处方药的新患者。就大麻而言,医生更愿意接受通过医疗计划(81.6%)而非其他渠道(60.2%)获得大麻的新患者。服用处方类阿片的慢性非癌症疼痛患者在获得医疗服务方面受到的限制似乎最大,尽管服用大麻的患者也可能遇到获得服务机会减少的问题。

Market Landscape and Insurer-Provider Integration: The Case of Ambulatory Surgery Centers 市场格局与保险商-提供商一体化:非住院手术中心案例

Insurer-provider integration is a new form of vertical integration, with increasing prominence in health care markets. While there are potential benefits from tighter alignment between providers and payers, risks of perverse impacts on health care markets loom large. Yet, little is known about this new wave of consolidation, which limits options for policy or regulatory responses. We focus on a dominant insurer’s acquisitions of Ambulatory Surgery Centers (ASCs) to document the growth and geographic spread of these ownership events. We find that a diverse swathe of the US has experienced an insurer-led ASC takeover. The acquisitions are also more frequently in areas where the insurer holds a higher enrollee market share at baseline; though, a linear prediction of the likelihood of ASC acquisition shows a more nuanced picture.
保险商-提供商一体化是一种新的纵向一体化形式,在医疗市场中的地位日益突出。虽然医疗服务提供者和支付者之间更紧密的合作可能带来好处,但对医疗市场造成不良影响的风险也很大。然而,人们对这一新的整合浪潮知之甚少,这限制了政策或监管对策的选择。我们将重点放在一家占主导地位的保险公司对非住院手术中心(ASCs)的收购上,以记录这些所有权事件的增长和地理分布。我们发现,美国不同地区都经历过保险公司主导的非住院手术中心收购。在保险公司基线时拥有较高参保者市场份额的地区,收购也更为频繁;不过,对收购 ASC 的可能性进行线性预测后,我们发现了一幅更为细致的图景。

The acquisitions are also more frequently in areas where the insurer holds a higher enrollee market share at baseline; though, a linear prediction of the likelihood of ASC acquisition shows a more nuanced picture.","PeriodicalId":502462,"journal":{"name":"Health Affairs Scholar","volume":"36 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357138","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}

Since January 2020, Medicare has covered opioid use disorder (OUD) treatment services at opioid treatment programs (OTPs), the only outpatient settings allowed to dispense methadone for treating OUD. This study examined policy-associated changes in Medicare acceptance and the availability of four OUD treatment services (ongoing buprenorphine, HIV/AIDS education, employment services, and comprehensive mental health assessment), by for-profit status, and county-level changes in Medicare-accepting-OTPs access, by sociodemographic characteristics (racial composition, poverty rate, and rurality). Using data from the 2019-2022 National Directory of Drug and Alcohol Abuse Treatment Facilities, we found Medicare acceptance increased from 21.31% in 2018 to 80.76% in 2021. The availability of the four treatment services increased but no increases were significantly associated with Medicare coverage. While county-level OTP access significantly improved, counties with higher rates of nonwhite residents experienced an additional average increase of 0.86 Medicare-accepting-OTPs (95% CI: [0.05, 1.67]) compared to those without higher rates of nonwhite populations. Overall, Medicare coverage was associated with improved OTP access, not ancillary services.
自 2020 年 1 月起,医疗保险(Medicare)将阿片类药物使用障碍(OUD)治疗服务纳入阿片类药物治疗项目(OTP)的承保范围,这是唯一允许配发美沙酮用于治疗 OUD 的门诊环境。本研究按营利状况研究了医疗保险接受度和四种 OUD 治疗服务(持续丁丙诺啡、艾滋病毒/艾滋病教育、就业服务和综合心理健康评估)可用性的政策相关变化,以及按社会人口特征(种族构成、贫困率和农村地区)研究了医疗保险接受 OTPs 的县级变化。利用《2019-2022 年全国药物和酒精滥用治疗机构目录》中的数据,我们发现医疗保险的接受度从 2018 年的 21.31% 提高到了 2021 年的 80.76%。四种治疗服务的可用性有所增加,但与医疗保险的覆盖率没有显著关联。虽然县级 OTP 的可及性明显改善,但与非白人居民比例较高的县相比,非白人居民比例较高的县平均增加了 0.86 个接受医疗保险的 OTP(95% CI:[0.05, 1.67])。总体而言,Medicare 的覆盖率与改善的 OTP 访问相关,而与辅助服务无关。

Follow the Money: A Global Analysis of Funding Dynamics for Global Health Security 跟着钱走:全球卫生安全筹资动态分析
Pub Date : 2024-06-06 DOI: 10.1093/haschl/qxae083

Global financing for health security was dramatically impacted by COVID-19. Here, we provide an empirical analysis of how that funding changed. Using data from Global Health Security (GHS) Tracking (ghscosting.tracking.org), we analyzed disbursements of direct financial assistance for global health security from 2016 to 2022 to compare pre-pandemic funding (2016-2019) to post-pandemic (2020-2022) funding for preparedness and response during each of the seven World Health Organization (WHO)-declared public health emergencies of international concern (PHEICs) from 2009 to 2022. Over $165B was disbursed for capacity-building and preparedness activities between January 2016 and December 2022, and over $76B was provided for PHEIC response. Preparedness funding remained evenly distributed since 2016 across regions, with the African region receiving about 70% of total preparedness funding. Indeed, how capacity-building and preparedness funding is distributed has changed remarkably little since 2016, despite unprecedented changes to the funding environment – including markedly increased spending – in response to COVID-19. This suggests we now have a unique opportunity to restructure how funds are tracked for accountability and assessing return on investment moving forward.
COVID-19 对全球卫生安全融资产生了巨大影响。在此,我们对资金的变化情况进行了实证分析。利用全球卫生安全(GHS)追踪系统(ghscosting.tracking.org)的数据,我们分析了 2016 年至 2022 年全球卫生安全直接财政援助的支付情况,比较了 2009 年至 2022 年世界卫生组织(WHO)宣布的七次国际关注的突发公共卫生事件(PHEIC)中每次疫情发生前(2016-2019 年)和疫情发生后(2020-2022 年)的备灾和响应资金。在 2016 年 1 月至 2022 年 12 月期间,为能力建设和备灾活动支付了超过 1,650 亿美元,为应对 PHEIC 提供了超过 760 亿美元。自 2016 年以来,备灾资金在各地区的分布依然均匀,非洲地区获得了备灾资金总额的约 70%。事实上,自 2016 年以来,能力建设和备灾资金的分配方式变化极小,尽管资金环境发生了前所未有的变化--包括因 COVID-19 而显著增加的支出。这表明,我们现在有一个独特的机会来调整资金的追踪方式,以促进问责制和评估投资回报。

Geographic variation in hardship, especially health-related hardship, was identified prior to and during the pandemic, but we do not know whether this variation is consistent among Veterans Health Administration (VHA)-enrolled Veterans, who reported markedly high rates of financial hardship during the pandemic, despite general and Veteran-specific federal policy efforts aimed at reducing hardship. In a nationwide, regionally stratified sample of VHA-enrolled Veterans, we examined whether the prevalence of financial hardship during the pandemic varied by Census region. We found Veterans in the South, compared to those in other Census regions, reported higher rates of severe-to-extreme financial strain, using up all or most of their savings, being unable to pay for necessities, being contacted by collections, and changing their employment due to the kind of work they could perform. Regional variation in Veteran financial hardship demonstrates a need for further research about the role and interaction of federal- and state- financial assistance policies in shaping risks for financial hardship as well as potential opportunities to mitigate risks among Veterans and reduce variation across regions.
在大流行之前和期间,人们发现了生活困难的地域差异,特别是与健康相关的困难,但我们不知道这种差异在退伍军人健康管理局(VHA)登记的退伍军人中是否一致,他们在大流行期间报告的经济困难率明显较高,尽管联邦政策和退伍军人具体政策旨在减少困难。我们在全国范围内对加入了退伍军人医疗协会的退伍军人进行了地区分层抽样,研究了大流行病期间经济困难的发生率是否因人口普查地区的不同而有所差异。我们发现,与其他人口普查地区的退伍军人相比,南部地区的退伍军人报告的严重至极度经济困难、用完全部或大部分积蓄、无法支付生活必需品、被催收以及因工作种类而更换工作的比例较高。退伍军人经济困难的地区差异表明,有必要进一步研究联邦和各州的经济援助政策在形成经济困难风险方面的作用和相互作用,以及降低退伍军人风险和减少地区差异的潜在机会。
