Background Reductions in blood pressure (BP) control among patients with hypertension were observed early in the COVID‐19 pandemic. The degree to which BP control may have returned to prepandemic levels is unknown. Methods Individuals aged 18 to 85 years with hypertension from 17 health systems participating in the National Patient‐Centered Clinical Research Network were identified using electronic health record data collected as part of routine care. BP control (percentage of patients whose most recent BP measurement was <140/<90 mm Hg) was estimated in a series of 12‐month rolling measurement periods from 2017 through 2022 (January 1, 2017 through December 31, 2017; April 1, 2017 through March 31, 2018; … January 1, 2022 through December 31, 2022). Differences in average BP control between 2022 (January 1, 2022 through December 31, 2022) and 2019 (January 1, 2019 through December 31, 2019) were estimated overall (adjusted for age, sex, and race and ethnicity) and by race and ethnicity (adjusted for age and sex). Results Our sample included 1 193 314 persons with hypertension in 2019 (48.9% aged 65–85 years, 52.9% men, 66.2% non‐Hispanic White) and 1 499 418 individuals in 2022 (50.6% aged 65–85 years, 47.1% men, 62.7% non‐Hispanic White). The weighted average BP control dropped from 65.3% in 2019 to 61.8% in 2020 and then partially recovered to 62.6% in 2022 (adjusted mean difference, −2.6 percentage points [95% CI, −5.0 to −0.2]). Non‐Hispanic Asian individuals experienced the largest temporal drop in BP control, declining from 68.4% in 2019 to 63.9% in 2022. Conclusions BP control was disrupted during the COVID‐19 pandemic and had not fully rebounded to prepandemic levels by the end of 2022. Continued surveillance is needed to determine whether the decline in BP control will persist and will result in future adverse cardiovascular events.

Abstract Background Neuroendocrine tumors (NETs) are rare, heterogeneous neoplasms associated with prolonged survival and substantial symptom burden. However, patient-reported outcomes across NET subtypes remain poorly characterized, particularly in real-world settings. This study describes baseline health-related quality of life (HRQoL) and care experiences among patients with gastroenteropancreatic and lung NETs, examining differences by tumor site and time since diagnosis. Methods The Neuroendocrine Tumors–Patient Reported Outcomes study is a prospective, multi-institutional US cohort of adults (aged 18 years and older) with incident small intestinal, pancreatic, gastroenteropancreatic, or lung NETs diagnosed from January 2018 through September 2024, identified via a validated electronic medical record–based computable phenotype. Baseline surveys assessed HRQoL, symptoms, care experiences, and clinical characteristics using validated instruments. Descriptive statistics and standardized mean differences compared responses by NET site and time since diagnosis. Results Among 2367 participants (mean age = 57.8 years; 57.3% female), 1974 had gastroenteropancreatic NETs (659 small intestinal NET, 555 pancreatic NET) and 393 had lung NETs. Fatigue (mean = 33.0), insomnia (mean = 32.5), and diarrhea (mean = 25.7) were the most burdensome symptoms. Lung NET patients reported worse dyspnea (standardized mean difference = 0.58, P &lt; .001) and lower physical, role, and global QoL scores than those with gastroenteropancreatic NETs, while pancreatic NET patients reported better functioning. Diarrhea worsened over time, especially in small intestinal NETs. Most rated care highly (75.3%) but cited concerns about treatment side effects (80.4%), costs (60.7%), and travel burden (58.8%). Conclusions This large US cohort reveals persistent symptom burden and HRQoL variation by tumor site and disease duration, underscoring the need for longitudinal HRQoL assessment in NET care.

Abstract Introduction: Recruitment for rare disease studies is challenging due to small eligible populations. Traditional clinical research management systems often lack tools to track recruitment contacts prior to enrollment. The NET-PRO study, focused on neuroendocrine tumors (NETs), implemented a participation monitoring system to enhance recruitment efficiency and representativeness. Methods: NET-PRO is a multicenter cohort study of 2538 adults diagnosed with gastroenteropancreatic (GEP) or lung NETs between January 2018 and September 2024. Recruitment occurred from January 2022 to February 2025 across 14 U.S. medical centers. Sites used flexible recruitment methods (email, mail, phone, in-clinic) and tracked contacts using REDCap-based tools. Participant characteristics were analyzed by enrollment mode (online or mail) and recruitment difficulty (number of contacts required prior to enrollment) using standardized mean differences, chi-square tests, and ANOVA. Results: Of 9279 contacted patients, 2675 consented (28.8%) and 2538 enrolled (27.4%). Most enrolled online (83.2%), while 16.8% enrolled by mail. Mail respondents were older, had lower education and income, and more comorbidities. Among those enrolled, recruitment difficulty was associated with older age, lower education and income, but not comorbidity. Over half of the most difficult-to-recruit participants enrolled online. Contact methods varied by attempt, with email dominating early contacts and phone/mail used more in later attempts. Conclusions: A participation monitoring tool supported flexible, multimodal recruitment and improved sample representativeness in a rare cancer study. Tracking recruitment contacts enabled adaptive strategies and may reduce bias in observational research by enabling better outreach to harder-to-reach populations.

Background: Nationally, many ASCVD patients fail to achieve an LDL-C <70 mg/dL, and uptake of both statin and non-statin therapies is low. The degree to which this varies across health systems is less clear. Methods: A cross sectional analysis was performed where lipid levels and lipid lowering therapies (LLT) were assessed using electronic health record data in patients with a previous diagnosis of ASCVD. The data was obtained across 14 US healthcare systems between 1/1/2021-12/31/2022. Proportions of patients with an active prescription of any statin, high intensity statin, ezetimibe, PCSK9i, and combination therapy (two or more agents) within 395 days of the most recent LDL-C value (index date) was evaluated overall and by participating site. Additionally, the proportion of patients with an LDL-C <70 mg/dL at the index date was also assessed. Results: Across 14 health systems, 1,118,623 patients with ASCVD were identified (median 61,840 per health system, range 8,161-182,315). Overall, 675,776 (60.4%) had an LDL-C level in the past year (range 39.1% - 70.8%). Of those with a lipid level, achievement of LDL-C <70 mg/dL ranged from 34.6-47.2%. In total, 42.6% were on any statin, 20.1% were on a high intensity statin, 4.3% on ezetimibe, and 1.2% on a PCSK9i. Only 2.9% were on combination therapy of a statin with ezetimibe or a PCSK9i. Variability was seen across health systems in utilization of each of these therapies, however even in the highest performing health systems, LLT uptake and achievement of LDL-C < 70mg/dL remained low ( Figure). Conclusion: Variability in utilization of LLT in ASCVD patients between health systems suggests that system-level factors may impact achieving guideline-based LDL-C goals. Despite the variability, the highest proportion of patients achieving an LDL-C <70mg/dL remained under 50% indicating the need for aggressive implementation efforts.

Abstract Purpose Sepsis disproportionately affects patients in rural and socially vulnerable communities. A promising strategy to address this disparity is provider‐to‐provider emergency department (ED)‐based telehealth consultation (tele‐ED). The objective of this study was to determine if county‐level social vulnerability index (SVI) was associated with tele‐ED use for sepsis and, if so, which SVI elements were most strongly associated. Methods We used data from the TELEmedicine as a Virtual Intervention for Sepsis in Rural Emergency Department study. The primary exposures were SVI aggregate and component scores. We used multivariable generalized estimating equations to model the association between SVI and tele‐ED use. Findings Our study cohort included 1191 patients treated in 23 Midwestern rural EDs between August 2016 and June 2019, of whom 326 (27.4%) were treated with tele‐ED. Providers in counties with a high SVI were less likely to use tele‐ED (adjusted odds ratio [aOR] = 0.51, 95% confidence interval [CI] 0.31‒0.87), an effect principally attributable to the housing type and transportation component of SVI (aOR = 0.44, 95% CI 0.22–0.89). Providers who treated fewer sepsis patients (1‒10 vs. 31+ over study period) and therefore may have been less experienced in sepsis care, were more likely to activate tele‐ED (aOR = 3.91, 95% CI 2.08‒7.38). Conclusions Tele‐ED use for sepsis was lower in socially vulnerable counties and higher among providers who treated fewer sepsis patients. These findings suggest that while tele‐ED increases access to specialized care, it may not completely ameliorate sepsis disparities due to its less frequent use in socially vulnerable communities.

Introduction: Guidelines are increasingly recommending a goal LDL-C <55 mg/dL in persons with atherosclerotic cardiovascular disease (ASCVD). The proportion and characteristics of US adults with ASCVD with an LDL-C <55 mg/dL remains unclear. Aims: To evaluate lipid management in ASCVD patients and factors associated with achieving an LDL-C <55mg/dL. Methods: Using electronic health record data from 8 US health systems, we evaluated LDL-C levels and treatment patterns in persons with prevalent ASCVD seen as outpatients between 1/1/2021-12/31/2021 with an LDL-C level within the prior year. Multivariable logistic regression modeling with generalized estimating equations was used to evaluate factors associated with an LDL-C <55 mg/dL. Results: Among 178,240 eligible ASCVD patients, 43.5% (77,472) had an LDL- C <70 mg/dL and 22.0% (39,270) had an LDL-C <55 mg/dL. Older age was associated with higher odds of LDL-C <55 mg/dL (OR 1.10 per 10 years, 95% CI 1.07-1.13), while female sex (OR 0.71, 95% CI 0.68-0.64) Black race (OR 0.77, 95% CI 0.70-0.86), and non-coronary artery disease forms of ASCVD including peripheral artery disease (PAD, OR 0.61, 95% CI 0.58-0.64) and cerebrovascular disease (CeVD, OR 0.72, 95% CI 0.66-0.79) were associated with lower odds of LDL-C <55 mg/dL in multivariable modeling. Overall, while 75.0% were on a statin, only 36.9% were on a high-intensity statin, 5.7% were on ezetimibe, and 1.7% were on a PCSK9i. Combination therapy was rare: only 4.2% were on a statin+ezetimibe, 0.5% on statin+PCSK9i, and 0.3% on all three. Conclusions: Less than a quarter of US patients with ASCVD achieve an LDL <55 mg/dL. Achieving this goal is even less common among younger adults, women, Black persons, and those with PAD and CeVD. Current therapeutic regimens often fail to use high-intensity statins, and markedly underutilize combinations of statins with ezetimibe and/or PCSK9 inhibitors.

Abstract Background Direct oral anticoagulation (DOACs) prevent stroke in patients with atrial fibrillation (AF) and have a superior safety profile compared with vitamin K antagonists (VKA). Yet, better definition of incidence and risk factors for major bleeding associated with DOACs in clinical practice may be important given emerging stroke prevention technologies, both pharmacologic and nonpharmacologic. Purpose To describe the incidence of and risk factors for major bleeding in individuals with AF on DOAC therapy. Methods We reviewed electronic health record data for two patient cohorts with AF prescribed DOACs: (1) Duke University Health System (DUHS) (2010–2018) and (2) Sites within the Patient-Centered Clinical Research Network (PCORnet) (2015–2019) which had ≥6 years assimilated data from both inpatient and outpatient encounters (7 sites). In each cohort, we assessed the 5-year incidence of major bleeding events defined as hospitalization for intracranial hemorrhage, or hospitalization for gastro-intestinal bleeding or procedure to control bleeding accompanied by transfusion within ±7 days or death within 30 days. Multivariable Fine-Gray proportional hazards modeling in each cohort was performed to evaluate independent risk factors for major bleeding on DOAC therapy. Results The cohorts included 10,625 patients (DUHS) and 58,321 patients (PCORnet) with AF. Major bleeding events occurred within 5 years of diagnosis in 639 (7.9%) of DUHS patients and 2568 (6.6%) of PCORnet patients (Table 1). The DUHS model predicted time to first major bleeding event with a C-index of 0.756 (95% CI 0.737, 0.775) and the PCORNet model had a c-index of 0.745 (0.736, 0.755) (Table 2). Independent factors associated with major bleeding consistent across both models (p&lt;0.001 in PCORnet for all unless noted) were higher CHA2DS2-VASc scores, lower eGFR, anemia (HR per 1-point increase in hemoglobin up to 12 g/dL 0.79 [0.76, 0.82]), prior major bleeding (HR 2.70 [2.22, 3.30]), cancer (HR 1.23 [1.12, 1.36]), recent cardiac surgery (HR 0.70 [0.51, 0.97]; p=0.030), alcohol use (HR 1.56 [1.29, 1.88]), aspirin use (HR 1.44 [1.32, 1.57]), and selective serotonin reuptake inhibitor use (HR 1.30 [1.19, 1.42]). Conclusions Across a large and geographically diverse contemporary population, risk of bleeding on DOAC for stroke prevention in AF remains a frequent and important clinical problem. There is an unmet need for stroke prevention therapies with improved safety profiles. We identified risk factors for major bleeding events on DOAC therapy, some of which are not represented in traditional risk scores, which may inform shared decision making for stroke prevention.

e19065 Background: Treatment decisions for patients with advanced stage (stages IIIB and IV) non-small cell lung cancer (AS NSCLC) are influenced by comorbidity at time of diagnosis. We studied the effects of comorbidity on survival and whether effects differ for short-term (120 days) vs. for long-term (>120 days) survival. Methods: Data were from surveys and medical records of 1498 patients withnewly diagnosed AS NSCLC in the Cancer Care Outcomes Research and Surveillance Consortium (CanCORS). Respiratory disease severity and comorbidities at diagnosis were measured from the Adult Comorbidity Evaluation (ACE-27) index and model fitting used the Akaike Information Criteria. The log-rank test was used for univariable survival models, and Cox proportional hazards regression for multivariable survival models. Results: Five comorbidities were significantly associated with survival and 437 (29.2%) patients had one or more of these. Survival to 120 days was significantly poorer for patients with a baseline diagnosis of stroke [hazard ratio (HR) 1.92; 95% confidence interval (CI) 1.26–2.93], diabetes (HR 1.33, 95% CI 1.08–1.65), or congestive heart failure (HR 1.45, 95% CI 1.07–1.96), controlling for age, gender, smoking status, stage, severe respiratory disease, and brain metastases. Given survival to 120 days (885 pts, 59%), survival beyond that was significantly poorer only for patients with baseline arrhythmia (HR 1.47, 95% CI 1.15–1.87) or end stage renal disease (HR 1.82, 95% CI 1.09–3.04), controlling for the covariates above. Adjustment for chemotherapy use had no effect on these associations. Conclusions: Several comorbidities present at diagnosis affected survival for AS NSCLC, with some comorbidities having a more immediate relationship to survival than others. Our finding provides information that could be used to tailor treatment decisions to patients’ comorbidities at diagnosis.
