Importance: Accurate patient understanding of prognosis is essential for informed decision-making to pursue therapies for advanced heart failure (HF).
Objectives: To evaluate (1) patient characteristics associated with overestimating survival with HF and (2) whether overestimation is associated with mortality.
Design, setting, and participants: This prospective cohort study was an exploratory secondary analysis of data from the multicenter US Registry Evaluation of Vital Information for Ventricular Assist Devices (VADs) in Ambulatory Life (REVIVAL) study. Participants were high-risk ambulatory patients with HF with reduced ejection fraction enrolled from July 2015 to June 2016. Data were analyzed from December 1, 2024, to December 16, 2025.
Exposures: Patient characteristics (eg, age) and estimation index (EI), defined as the ratio of patient-estimated life expectancy to Seattle Heart Failure Model (SHFM)-estimated mean survival (EI <0.5, discordantly pessimistic; 0.5 to <1.5, concordant; and ≥1.5, discordantly optimistic).
Main outcomes and measures: Primary outcomes were EI and 2-year all-cause mortality. Factors associated with EI were estimated using ordered logistic regression. Association between EI and mortality was assessed using a cause-specific Cox proportional hazards regression model with VAD and heart transplant as censoring events.
Results: A total of 296 high-risk, ambulatory patients with chronic HF were included; 223 (75.3%) were male, and mean (SD) age was 60.1 (11.5) years. The median SHFM-estimated survival was 8.2 years (IQR, 5.1-12.1 years), and median patient-estimated life expectancy was 7.0 years (IQR, 5.0-10.0 years). In all, 98 patients (33.1%) were discordantly optimistic. Increasing EI was associated with increased mortality in the univariable model, which was attenuated with multivariable adjustment (adjusted hazard ratio [AHR] for concordant optimism, 1.21 [95% CI, 0.49-2.99] and for discordant optimism, 2.23 [95% CI, 0.94-5.33] vs discordant pessimism). Compared with discordantly pessimistic or concordantly optimistic estimates (EI <1.5), discordant optimism was associated with increased hazard of 2-year mortality (AHR, 1.98; 95% CI, 1.04-3.77) but a similar hazard for a VAD or heart transplant compared with discordant pessimism (HR, 1.24; 95% CI, 0.64-2.41) in a post hoc analysis.
Conclusions: In this cohort study, discordant optimism regarding life expectancy compared with model estimates was common and associated with mortality that was not due to a lower probability of receiving a heart transplant or VAD. The findings suggest clinicians should objectively evaluate HF risk when considering advanced therapies, rather than relying primarily on patient-reported symptoms.

Importance: Hospital-based opioid treatment (HBOT) can improve outcomes for patients with opioid use disorder, but little is known about specific attributes and supports needed for clinical champions to successfully implement HBOT.
Objective: To identify characteristics and supports of effective clinical champions implementing HBOT in US hospitals.
Design, setting, and participants: Qualitative study using postimplementation semistructured interviews conducted with individuals highly involved in HBOT implementation, including champions and hospital staff at 12 US community hospitals randomized to the high-intensity group of the Exemplar Hospital Initiation Trial to Enhance Treatment Engagement, a national implementation trial comparing low- and high-intensity HBOT implementation strategies. Interviews explored implementation experiences over 24 months from December 2021 to December 2023. Interviews were audio recorded, transcribed, and coded. The framework method and in-depth thematic analysis were used to explore the role of champions.
Interventions: All hospitals received a best-practices manual, video webinar series, and hub team support for questions, while hospitals randomized to the high-intensity group also received monthly practice facilitation, telementoring, and 10% effort funding for a local champion. Champions led HBOT implementation with support from regional hubs with HBOT expertise.
Measures: Effective champions were defined as those perceived by staff to successfully lead HBOT implementation. Open-ended questions and thematic analysis explored participants' perspectives on attributes of effective champions and how they overcame implementation barriers.
Results: A total of 31 hospital staff (15 physicians, 5 executives, 5 pharmacists, 2 nurse practitioners, 2 social workers, 1 nurse, and 1 addiction counselor) were interviewed. Effective champions were perceived as respected hospital "insiders" with institutional influence, persistence, and systems change skills. They built multidisciplinary teams, developed standard workflows, and used emotionally resonant strategies (eg, patient narratives) to overcome stigma and engage hospital leadership. Champions could be effective without addiction medicine expertise, particularly when provided with protected time, hospital leadership support, and external practice facilitation from addiction experts.
Conclusions and relevance: This multisite qualitative study underscores the vital role of champions in expanding hospital-based opioid care. To ensure HBOT expansion, hospitals should invest in champions, protected time, leadership backing, and external supports that legitimize and routinize evidence-based addiction care.

重要性:载脂蛋白L1位点(APOL1)高危等位基因与非洲血统人群中慢性肾脏疾病(CKD)的发病率相关。很少有研究检查遗传结果返回对血压管理和控制的影响。目的:探讨向高血压患者及其临床医生提供APOL1高危基因型结果是否能降低收缩压(SBP),提高CKD的筛查和诊断水平。设计、环境和参与者:从2020年7月1日到2023年9月30日,在美国14个机构和54个临床站点招募了年龄在18至70岁之间、自我报告为非洲血统的高血压患者。符合条件的患者要么(1)没有糖尿病和CKD的诊断,要么(2)有CKD合并或不合并糖尿病的诊断。干预:参与者被随机分为立即(干预)或入组后6个月(对照组)接受APOL1基因型结果。临床决策支持鼓励适当的CKD筛查、诊断和抗高血压治疗。主要结局和指标:主要结局是APOL1高危等位基因患者在3个月时收缩压的变化,通过改进的意向治疗分析进行评估。预先指定的每个方案亚组分析包括血压不控制(基线收缩压≥140 mm Hg或舒张压≥90 mm Hg),接受降压治疗时血压不控制和入组时CKD的患者。次要结局包括尿微量白蛋白筛查和新的CKD诊断。结果:6754名受试者(平均[SD]年龄55.3[10.3]岁;4310名女性[63.8%])中,954名(14.1%;平均[SD]年龄54.9[10.0]岁;600名女性[62.9%])有2个APOL1风险等位基因。3个月时,干预组与对照组收缩压无差异(组间差异为-0.3 mm Hg [95% CI, -2.7至2.1 mm Hg])。在377例血压未控制的个体中,干预组的平均收缩压变化比对照组多-4.1 mm Hg (95% CI, -7.7 ~ -0.5 mm Hg) (P = 0.004)。在接受降压治疗的血压不受控制的患者亚组中,干预也观察到收缩压改善(SPB差值,-4.3 mm Hg [95% CI -8.0 ~ -0.5 mm Hg]; P =。004),但CKD亚组没有(SPB差异,0.8 mm Hg [95% CI, -3.0至4.5 mm Hg])。提供APOL1基因型导致尿微量白蛋白筛查增加(组间差异为17.3% [95% CI, 9.6%-24.9%]; P结论及相关性:向参与者和临床医生提供APOL1基因型高危结果与总体收缩压降低无关。在未控制血压的患者亚组中,干预组有明显的收缩压降低。APOL1的披露也增加了CKD的筛查和诊断率。报告APOL1基因型对未控制血压患者的影响值得进一步研究。试验注册:ClinicalTrials.gov标识符:NCT04191824。

Importance: Private equity investment in US health care, including substance use disorder treatment, has grown. However, the implications of private equity acquisition of substance use disorder treatment facilities for buprenorphine access and quality of care are unknown.
Objective: To examine the associations of private equity acquisition of substance use disorder treatment facilities and buprenorphine prescribing patterns.
Design, setting, and participants: In this cross-sectional study using difference-in-differences analysis, aggregate prescription claims from an analytical dataset for buprenorphine from acquired substance use disorder treatment facilities were compared with those from nonacquired facilities from 2019 quarter 3 through 2021 quarter 2. Prescriptions for buprenorphine filled by adult individuals (aged >18 years) were included in the analyses. An event study difference-in-differences design was used to assess changes in buprenorphine prescribing characteristics at facilities from 4 quarters before to 4 quarters after acquisition using a linear model adjusted for facility, year, and treatment cohort characteristics. Analyses were performed from January 2025 to December 2025.
Main outcomes and measures: Patient volume, prescription volume, payer mix, and treatment retention duration.
Results: In a sample of 90 acquired facilities and 2374 never-acquired facilities, private equity acquisition was associated with increases in patient volumes. Acquisition was associated with a mean increase of 65.66 (95% CI, 30.57-100.76; P < .001) patients receiving buprenorphine per facility quarter. Similarly, acquisition was associated with a mean increase of 163.90 (95% CI, 47.07-280.73; P = .006) buprenorphine prescriptions per facility quarter. Acquisition was associated with an increase of 0.73 (95% CI, 0.07-1.40; P = .03) percentage points in prescriptions paid with cash compared with the control group. Other payer types were not associated with acquisition. Measures of treatment episode duration decreased after acquisition, with decreases of 6.24 (95% CI, -11.47 to -1.00; P = .02) percentage points in 90-day retention and 7.91 (95% CI, -13.96 to -1.86; P = .01) percentage points in 180-day retention.
Conclusion and relevance: In this study, the volume of patients treated with buprenorphine increased after private equity acquisition, with minimal changes in the payer mix among these patients. However, the quality of treatment, in terms of buprenorphine retention duration, decreased after acquisition. These results underscore the need for oversight mechanisms and continued research to ensure incentives for private investment in addiction care align with delivery of high-quality evidence-based treatment.
