INTRODUCTION: Recurrent Clostridioides difficile infection (rCDI) is associated with substantial morbidity, healthcare utilization, and costs. US FDA-approved microbiota-based therapies, fecal microbiota spores, live-brpk (VOS) and fecal microbiota, live-jslm (RBL), reduce recurrence risk, but cost-effective placement within the rCDI treatment pathway remains uncertain. METHODS: We performed a US payer-perspective cost-effectiveness analysis using decision-tree modeling according to CHEERS 2022 guidelines. Adults with rCDI entered the model after the first or second recurrence and were followed for <1 year. Effectiveness inputs were derived from ECOSPOR III/IV (VOS), PUNCH CD3/CD3-OLS (RBL) trials, and published literature for standard-of-care (SoC) comparators. Outcomes included costs (2025 USD), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). Probabilistic and deterministic sensitivity analyses were performed using a willingness-to-pay threshold (WTP) of $150,000/QALY. ICERs were interpreted across $50,000, $100,000, $120,000, and $150,000/QALY. RESULTS: After the first recurrence, RBL was cost-effective vs SoC alone ($25,415/QALY). Early initiation remained favorable compared with delayed use for VOS ($27,239/QALY) and RBL ($26,704/QALY). After the second recurrence, VOS remained cost-effective vs SoC (ICER $53,983/QALY), whereas RBL exceeded the WTP threshold (ICER $171,496/QALY). Exploratory cross-trial VOS vs RBL comparisons yielded ICERs of $124,636/QALY after first recurrence and $137,350/QALY after second recurrence, indicating threshold-sensitive product-to-product comparisons. DISCUSSION: Earlier initiation of microbiota-based therapies after the first rCDI provides greater health benefits at acceptable cost-effectiveness thresholds compared with delayed use, supporting earlier integration into rCDI treatment strategies. VOS vs RBL comparisons should be interpreted as exploratory indirect comparisons pending comparative real-world or head-to-head data.

ABSTRACT Introduction Frailty is increasingly recognized as an important determinant of outcomes in cardiovascular disease, yet its population‐level impact among patients hospitalized with cardiac implantable electronic device (CIED) infections remains incompletely defined. We examined the prevalence of frailty and its association with clinical outcomes and utilization of transvenous lead removal (TLR) in a contemporary national cohort. Methods and Results We analyzed the National Readmissions Database from 2016–2021 to identify adults hospitalized for CIED infections. Frailty was defined using the Johns Hopkins adjusted clinical groups frailty‐defining diagnoses. Of 288,402 patients hospitalized with CIED infections, 25.1% were classified as frail. Frail patients experienced significantly higher in‐hospital mortality (10.8% vs. 4.6%), 30‐day mortality (9.2% vs. 5.5%), complications, longer length of stay, lower rates of discharge home, and higher 30‐day readmissions compared with non‐frail patients (all p < 0.01). TLR was performed less frequently in frail patients (10.8% vs. 13.4%; adjusted odds ratio [aOR] 0.80, 95% CI 0.76–0.83). On adjusted analyses, TLR was independently associated with lower in‐hospital mortality, 30‐day mortality, and 30‐day readmissions in both frail and non‐frail patients. Conclusion Among patients hospitalized with CIED infections, TLR was independently associated with lower mortality and readmissions in both frail and non‐frail patients, despite lower utilization in frail individuals. Frailty was common (25.1%) and independently associated with significantly worse outcomes. These findings highlight important associations between frailty, treatment patterns, and outcomes that warrant prospective evaluation.

ObjectivePatients with rheumatoid arthritis (RA) frequently visit emergency departments (EDs), but their clinical characteristics and admission factors are poorly understood. Our study investigates the epidemiology and outcomes of ED visits among patients with RA using the Nationwide Emergency Department Sample (NEDS).MethodsThis cross‐sectional study used the 2019 NEDS data to identify RA‐related ED visits using International Classification of Disease, Tenth Revision codes M05.X or M06.X. RA‐related ED visits were defined as encounters in which RA was recorded in any diagnostic position. Demographics, clinical features, and comorbidities were compared between RA and non‐RA ED visits. Racial variations were assessed, and multivariable logistic regression identified factors associated with inpatient admission.ResultsWe identified 905,811 (0.8%) ED visits for adults aged ≥18 years with RA. Compared to non‐RA visits, RA ED visits had a higher proportion of patients aged ≥65 years, women, White patients, and Medicare‐insured individuals with a greater comorbidity burden. Admission rates were 46% for RA visits versus 16% for non‐RA visits. Black and Hispanic patients with RA were younger than White patients and more likely to belong to the lowest income quartile. Older age, male sex, and comorbidities were associated with higher admission odds, whereas Black race, lowest income quartile, and Medicaid coverage correlated with lower odds of admission. Septicemia was the most common primary ED diagnosis in patients with RA.ConclusionPatients with RA visiting the ED were older, had a higher comorbidity burden, and were three times more likely to be admitted than patients without RA. Black patients and those in the lowest income quartile had lower odds of admission, highlighting potential disparities and the need for targeted interventions to improve health equity.
