This retrospective study estimated 30-day hospital readmission rates between patients who did and did not use roflumilast among those with COPD hospitalizations.Methods: Data were from MarketScan, a large US commercial health insurance claims database. Patients aged ≥40 years with at least one hospitalization for COPD between 2010 and 2011 were included. The roflumilast group included patients who used roflumilast within 14 days after the first hospitalization (index), while the comparison group (non-roflumilast) included patients who did not use roflumilast during the study period. Continuous enrollment for at least 6 months before and 30 days after the index date was required. The 30-day hospitalization rate was calculated after the index hospitalization. Conditional logistic regression with propensity score 1:3 matching was employed to assess the difference in 30-day hospital readmission rates between the roflumilast and non-roflumilast groups, adjusting for baseline characteristics, comorbidity, health care utilization, and COPD medication use within 14 days after the index date.Results: A total of 15,755 COPD patients met the selection criteria, ie, 366 (2.3%) in the roflumilast group and 15,389 (97.7%) in the non-roflumilast group. The mean (± standard deviation) age was 71±12.5 years and 52% were female. After propensity score matching, all-cause 30-day hospitalization rates were 6.9% and 11.1% in the roflumilast and non-roflumilast groups, respectively. COPD-related 30-day hospitalization rates were 6.3% and 9.2% in the roflumilast and non-roflumilast groups, respectively. Conditional logistic regression identified a significantly lower likelihood of all-cause 30-day readmission (odds ratio 0.59, 95% confidence interval 0.37–0.93, P=0.023) for roflumilast patients relative to non-roflumilast patients.Conclusion: This study showed, in a real-world setting, that use of roflumilast was associated with a lower rate of hospital readmission within 30 days among patients hospitalized for COPD.Keywords: chronic obstructive pulmonary disease, roflumilast, health care utilization, hospital readmission

BACKGROUND: To date, few postmarketing studies have addressed whether long-term prophylactic treatment with second-generation antidepressants (ADs) delays depressive episodes in patients with bipolar disorder. OBJECTIVE: The aim of this study was to compare the risk of depressive relapse between patients with bipolar disorder who took second-generation ADs>-6 months after depressive remission with those who discontinued AD use early. METHODS: Using a large US managed-care claims database, continuously enrolled bipolar subjects who took second-generation ADs after a depressive remission were identified between January 1, 1998, and December 31, 2002. Duration of AD and concurrent mood stabilizer use were based on coded diagnoses and pharmacy records. A Cox proportional hazards model was developed to predict time from depressive remission to next depressive relapse with continuous AD use, categorized as either >or=6 months or <6 months. Propensity scoring with greedy matching was used to help balance the observed background covariates and baseline disease severity between groups. RESULTS: Five hundred eighty-nine subjects met the inclusion criteria. A Kaplan-Meer estimate found that the median depressive relapse times for the continuous (ie, >or=6 months) and early discontinuation (ie, <6 months) AD treatment groups were 16.5 and 6.8 months, respectively (P<0.05). The Cox proportional hazards model with propensity score matching identified a significantly lower risk of depressive relapse over a 2-year period among those who continued AD treatment>or=6 months after remission, compared with those who discontinued treatment within 6 months (hazard ratio, 0.61 [95% CI, 0.42-0.88]; continuous vs early discontinuation, P<0.01). CONCLUSIONS: Continuous second-generation AD therapy for >or=6 months after depressive remission was associated with a lower risk of depressive relapse over a 2-year period in patients with bipolar depression. Given concerns regarding the risk of AD users with bipolar disorder switching to mania, an optimal prophylactic treatment after depressive remission should balance the risks between manic switching and depressive relapse.

Abstract: This study provides empirical evidence regarding the income productivity of health human capital in China. We appeal to concepts from human capital theory to support a basic model that treats health as a form of human capital in the income production process. Our model examines the economic return at the household level from the health of its individual members. We estimate this with a longitudinal sample drawn from the China Health and Nutrition Survey (CHNS), allowing us to exploit “within” variation in health and income to address possible unobservables biasing estimates of the impact of health on income in the simple cross-sectional setting. Household income is strongly influenced by the health of its members, particularly in rural areas. These findings could have important implications for health and economic policy-making aimed at reducing the long-standing urban–rural economic gap and more comprehensively insuring the rural population against health and economic risk.

Introduction: Daratumumab, lenalidomide, and dexamethasone (DRd) and bortezomib, lenalidomide, and dexamethasone (VRd) are the only preferred treatment regimens for patients with transplant-ineligible (TIE) newly diagnosed multiple myeloma (NDMM). As there are no randomized head-to-head studies of DRd versus VRd, this analysis aimed to compare real-world time-to-next-treatment (TTNT) or death in this population., Methods: Patients with NDMM who received front-line (FL) DRd or VRd were identified from the Acentrus database (January 1, 2018 to May 31, 2023). Those with a record of a stem cell transplant or aged < 65 years were excluded to limit analysis to the TIE population. Inverse probability of treatment weighting was used to balance baseline patient characteristics. A doubly robust Cox proportional hazards model was used to compare TTNT or death between cohorts., Results: A total of 149 and 494 patients who initiated DRd and VRd, respectively, were identified. After weighting (weighted N DRd  = 302, weighted N VRd  = 341), cohorts had similar baseline characteristics. Of these, 98 (32.4%) DRd and 175 (51.2%) VRd patients either received a subsequent line of therapy or died, with a median TTNT or death of 37.8 months in the DRd cohort and 18.7 months in the VRd cohort (hazard ratio: 0.58, 95% confidence interval: 0.35, 0.81; p < 0.001)., Conclusion: Treatment of TIE NDMM patients with DRd led to a significantly longer TTNT or death compared to VRd, evidenced by a 42% risk reduction, supporting the effectiveness of DRd over VRd as FL treatment in this patient population., (© 2024 Janssen Scientific Affairs, LLC.

Introduction: Daratumumab plus lenalidomide and dexamethasone (D-Rd) and bortezomib plus lenalidomide and dexamethasone (VRd) are commonly used treatment combinations for transplant-ineligible (TIE) patients with newly diagnosed multiple myeloma (NDMM). D-Rd and VRd demonstrated superior efficacy relative to lenalidomide and dexamethasone (Rd) in the MAIA and SWOG S0777 trials, respectively, but have not been compared directly in a head-to-head trial. Naïve comparisons of efficacy across the two trials may be biased because MAIA enrolled only TIE patients (median age 73 years), whereas SWOG S0777 enrolled both TIE patients and transplant-eligible patients who chose to defer/refuse frontline stem cell transplantation (median age 63 years). The present study compared progression-free survival (PFS) in TIE patients with NDMM treated with D-Rd versus VRd based on an adjusted indirect treatment comparison (ITC) that leveraged individual patient-level data from MAIA and SWOG S0777., Methods: Harmonized inclusion/exclusion criteria (including age ≥ 65 years as a proxy for transplant ineligibility) and propensity-score weighting were used to balance the trial populations on measured baseline characteristics. After differences in trial populations were adjusted for, an anchored ITC was performed wherein within-trial PFS hazard ratios (HRs) for D-Rd versus Rd and VRd versus Rd were estimated and used to make indirect inference about PFS for D-Rd versus VRd., Results: PFS HRs were 0.52 (95% confidence interval [CI] 0.41-0.67) for D-Rd versus Rd based on MAIA data, 0.88 (95% CI 0.63-1.23) for VRd versus Rd based on SWOG S0777 data, and 0.59 (95% CI 0.39-0.90) for the Rd-anchored ITC of D-Rd versus VRd. Sensitivity and subgroup analyses produced results consistent with the primary results., Conclusion: This anchored ITC demonstrated a greater PFS benefit for D-Rd versus VRd in TIE patients with NDMM. In the absence of head-to-head trials comparing D-Rd and VRd, the present trial may help inform treatment selection in this patient population., (© 2024. The Author(s).)

Background: Daratumumab, lenalidomide and dexamethasone (DRd) and bortezomib, lenalidomide and dexamethasone (VRd) are preferred regimens for transplant ineligible (TIE) patients with newly diagnosed multiple myeloma (NDMM). Both DRd and VRd demonstrated superior efficacy versus Rd in the MAIA and SWOG S0777 trials, respectively, but there is no head-to-head (H2H) clinical trial comparing their efficacy. Differing populations in the MAIA and S0777 trials make an unadjusted comparison of outcomes challenging and biased. The current TAURUS study is the first real-world H2H study comparing progression-free survival (PFS) among TIE NDMM patients treated with DRd or VRd as first-line (1L) in similar clinical settings., Materials and Methods: A multicenter chart review study was conducted at nine sites across the United States. All TIE patients treated with DRd and a randomly selected population of VRd patients were included. TIE NDMM patients aged ≥65 were included if they initiated 1L DRd/VRd between January 2019 and September 2021. PFS was defined as the time from DRd/VRd initiation until disease progression or death. A doubly-robust multivariable Cox regression model combined with inverse probability of treatment weighting (IPTW) methodology was used to compare PFS between cohorts., Results: Weighted cohorts comprised 91 DRd and 87 VRd patients. Thirteen DRd and 24 VRd patients experienced progression/death. Patients treated with DRd had a lower risk of progression/death versus VRd (adjusted hazard ratio: 0.35, 95% confidence interval: [0.17; 0.73])., Conclusion: DRd is associated with a significantly lower risk of disease progression or death compared to VRd as 1L treatment for TIE NDMM patients., (Copyright © 2023 The Author(s).

Background: Multiple studies report racial disparities in antipsychotic prescription patterns. This study assessed demographic and clinical factors associated with the utilization of first-generation (FG) versus second-generation (SG) long-acting injectable (LAI) antipsychotics., Methods: This retrospective, observational cohort analysis used claims data from the IBM MarketScan® Multi-State Medicaid database. The study included adults with an LAI claim between 01-January-2009 and 31-December-2018, an ICD-9-CM or ICD-10-CM diagnosis of schizophrenia, race recorded as Black or White, and ≥12 months of continuous enrollment before the index LAI. Descriptive analysis detailed the relationship between race and FG or SG LAI initiation. Multivariate logistic regression was used to assess potential associations with FG vs. SG LAI initiation, including clinical and demographic factors, comorbidities, and index year., Results: A total of 10,773 patients were included: 6659 (62 %) Black and 4114 (38 %) White. Black patients had a higher utilization of FG LAIs than White patients (46.8 % vs. 38.9 %) over the 10 years analyzed. Black patients were more likely to utilize FG LAIs than White patients (odds ratio: 1.47; 95 % CI: 1.34, 1.62) after controlling for index year and covariates (race, age, gender, insurance plan type, Quan-Charlson Comorbidity index score, comorbidities, prior medications). Significant predictors of FG LAI utilization were older age, type of baseline oral antipsychotic (FG vs SG), type of coverage (managed care vs fee for service), and greater comorbidity burden., Conclusion: The utilization of FG LAIs was greater in Black compared to White Medicaid beneficiaries with schizophrenia over a 10-year period. These findings suggest that racial disparities exist in LAI initiation, with implications for differential quality of schizophrenia treatment., Competing Interests: Declaration of competing interest Jacqueline Pesa, Zhiwen Liu, Alex Z.

Introduction: In patients with psoriatic arthritis (PsA), potential differences in care by race/ethnicity have not been well studied., Methods: This retrospective, observational cohort analysis utilized the IBM MarketScan ® Multi-State Medicaid database. Patients aged ≥ 18 years with two or more PsA-related claims between January 1, 2010 and December 31, 2019, and ≥ 12 months of continuous enrollment before the first diagnosis of PsA (index date) were included. Outcomes evaluated were the use of disease-modifying antirheumatic drugs (DMARDs) overall and by type (conventional synthetic, biologic, targeted synthetic) within 12 months following initial PsA diagnosis, as well as the time to DMARD initiation after initial PsA diagnosis, stratified by race/ethnicity. Multivariate Cox proportional hazards models were used to assess potential associations between patient baseline characteristics and time to DMARD initiation., Results: Among patients with newly diagnosed PsA (N = 3432), the mean age was 44.4 years, 69.9% were female, 77.4% were White, and 10.1% were Black. Of the 2993 patients with at least 12 months of follow-up, fewer Black patients received any DMARD therapy compared with White patients (68.4 vs. 76.4%, respectively, p = 0.002), and, specifically, a lower percentage of Black patients received biologic DMARDs compared with White patients (33.6 vs. 42.6%, respectively, p = 0.003). After adjusting for baseline characteristics, Black patients had significantly longer time to initiation of any DMARD (HR [95% CI] 0.82 [0.71-0.94]) and biologic DMARD (0.84 [0.71-0.99]) compared with White patients. Other baseline variables such as older age, anxiety, and hepatitis C were also significantly associated with longer time to any DMARD initiation after initial PsA diagnosis., Conclusions: Time to treatment initiation was significantly longer in Black patients compared with White patients with newly diagnosed PsA. These findings suggest care delivery disparities in patients with PsA and highlight the need for future studies to understand factors that drive the observed differences in drug therapy by race/ethnicity., (© 2023.

Daratumumab (DARA) is an anti-CD38 monoclonal antibody approved as a combination therapy for newly diagnosed multiple myeloma (MM) and as monotherapy and combination therapy for relapsed or refractory MM cases. We assessed the length of DARA use across lines of therapy and the probabilities of treatment discontinuation in patients with MM in the real-world. We used the deidentified Clinformatics Data Mart database from Optum to identify patients with MM (n=2124) who received DARA-containing treatment between November 1, 2015 and March 31, 2021 in the United States. Patients were excluded if they had received a stem cell transplant. The duration of DARA use was defined as the time interval between the first initiation and discontinuation of DARA as a time-to-event outcome using the Kaplan-Meier method. A gap of more than 60 days between 2 consequent DARA claim dates was defined as DARA discontinuation. The median duration of continuous DARA use was 16.6 months. By 24 months, 33.1% of patients remained on DARA treatment. In a subgroup analysis of patients with 12 months or more continuous insurance coverage (n=1246), the median length of DARA use was 24.7 months; by 24 months, 51.8% remained on DARA treatment. The dose adherence ratios (observed DARA doses relative to the label) were close to 1.0, particularly among patients with longer follow-up, indicating that real-world DARA dosing frequency was similar to that on the approved label. In summary, this real-world analysis reported that the median duration of continuous DARA use is 16.6 months, with high dosing adherence in patients who have MM., Competing Interests: R.F. served as a consultant for AbbVie, Aduro, Amgen, Bayer, Bristol Myers Squibb, Celgene, GSK, Janssen, Juno, Kite Pharma, Merck, Novartis, ONCOtracker, Pharmacyclics, Sanofi, and Takeda; participated in scientific advisory boards for Adaptive Biotechnologies and ONCOtracker, Board of Directors Antegene.

BACKGROUND: The Disease Recovery Evaluation and Modification study (DREaM; NCT02431702) assessed the benefit of initiating paliperidone palmitate (PP), a long-acting injectable antipsychotic, in patients with recent-onset schizophrenia or schizophreniform disorder. OBJECTIVE: To determine whether reductions in psychiatric hospitalizations with early initiation of PP vs oral antipsychotic (OAP) therapy observed in a DREaM post hoc analysis are transportable to a real-world population of patients with recent-onset schizophrenia. METHODS: Patients enrolled in DREaM were randomized to receive OAP or PP for 9 months, after which OAP recipients were re-randomized to receive OAP or PP for another 9 months. We used this design to form treatment arms: OAP-OAP, OAP-PP, and PP-PP. Inclusion/exclusion criteria were used to identify a Medicaid Managed Care (MMC) OAP-treated cohort of 1,000 patients diagnosed with schizophrenia using IBM Truven databases from 2015 to 2019. The MMC cohort was combined with the subset of patients diagnosed with schizophrenia enrolled in DREaM from US sites (N = 45, 43, and 44 for OAP-OAP, OAP-PP, and PP-PP, respectively). Propensity scores for the MMC cohort were estimated using baseline variables identified via double-lasso regression. Estimated propensity scores were used to weight psychiatric hospitalizations in the DREaM OAP-OAP group and compared with observed MMC OAP cohort psychiatric hospitalizations. After the successful calibration of the DREaM OAP-OAP group, similar approaches were taken for the OAP-PP and PP-PP groups to transport DREaM effects to MMC data. RESULTS: Standardized mean differences in baseline covariates between DREaM treatment arms and MMC groups were substantially reduced after calibration. The 18-month cumulative numbers of psychiatric hospitalizations per patient (SE) were 0.83 (0.14) for the MMC cohort, 0.43 (0.14) for the unweighted OAP-OAP, and 0.80 (0.37) for the calibrated OAP-OAP. The difference between the calibrated OAP-OAP and MMC was not statistically significant (difference, 0.03 [95% CI = -0.67 to 0.81]), indicating successful calibration. The mean difference in 18-month cumulative psychiatric hospitalizations relative to the MMC cohort was -0.77 (95% CI = -1.08 to -0.47) for OAP-PP and -0.83 (95% CI = -1.15 to -0.60) for PP-PP. CONCLUSIONS: Our study demonstrates that results from the DREaM OAP-OAP group reflect psychiatric hospitalizations in a real-world population when calibrated using specific baseline characteristics. Transporting the DREaM effects, we find that using OAP-PP and PP-PP treatment strategies for patients with recent-onset schizophrenia in the MMC population could reduce psychiatric hospitalizations compared with the use of OAP. These findings, along with the potential reduction in associated costs, should be considered when assessing the value of PP formulations.

Background: Addition of temozolomide (TMZ) to radiotherapy (RT) improves overall survival (OS) in patients with glioblastoma (GBM), but previous studies suggest that patients with tumors harboring an unmethylated MGMT promoter derive minimal benefit. The aim of this open-label, phase III CheckMate 498 study was to evaluate the efficacy of nivolumab (NIVO) + RT compared with TMZ + RT in newly diagnosed GBM with unmethylated MGMT promoter., Methods: Patients were randomized 1:1 to standard RT (60 Gy) + NIVO (240 mg every 2 weeks for eight cycles, then 480 mg every 4 weeks) or RT + TMZ (75 mg/m2 daily during RT and 150-200 mg/m2/day 5/28 days during maintenance). The primary endpoint was OS., Results: A total of 560 patients were randomized, 280 to each arm. Median OS (mOS) was 13.4 months (95% CI, 12.6 to 14.3) with NIVO + RT and 14.9 months (95% CI, 13.3 to 16.1) with TMZ + RT (hazard ratio [HR], 1.31; 95% CI, 1.09 to 1.58; P = .0037). Median progression-free survival was 6.0 months (95% CI, 5.7 to 6.2) with NIVO + RT and 6.2 months (95% CI, 5.9 to 6.7) with TMZ + RT (HR, 1.38; 95% CI, 1.15 to 1.65). Response rates were 7.8% (9/116) with NIVO + RT and 7.2% (8/111) with TMZ + RT; grade 3/4 treatment-related adverse event (TRAE) rates were 21.9% and 25.1%, and any-grade serious TRAE rates were 17.3% and 7.6%, respectively., Conclusions: The study did not meet the primary endpoint of improved OS; TMZ + RT demonstrated a longer mOS than NIVO + RT. No new safety signals were detected with NIVO in this study. The difference between the study treatment arms is consistent with the use of TMZ + RT as the standard of care for GBM.ClinicalTrials.gov NCT02617589., (© The Author(s) 2022.

Background: Inflammatory bowel disease (IBD) is a chronic disease with the potential for significant morbidity in case of suboptimal treatment (e.g. low treatment adherence). In spite of immense research in IBD, literature on association of IBD with race/ethnicity is fragmented. In this study, we aimed to evaluate the association between race/ethnicity and treatment adherence and persistence among patients with Crohn's disease (CD) or ulcerative colitis (UC) initiated with biologic therapies., Methods: This observational, retrospective study utilized the Optum Clinformatics (Optum) Extended Data Mart Socioeconomic Status (SES) database. Adult patients with ≥ 2 medical claims for CD or UC diagnosis, ≥ 1 medical or pharmacy claim for corresponding FDA-approved biologic therapy, and a ≥ 12-month pre-index (index date: date of the first biologic medical/pharmacy claim) continuous health plan enrollment were included. Treatment adherence was measured as the proportion of days covered of ≥ 80% and treatment persistence by the number of days from the index date to the biologics discontinuation date. Switching among biologics was allowed for both treatment adherence and treatment persistence. Multivariable regression analyses were performed to evaluate the association between race/ethnicity and treatment adherence/persistence., Results: Among patients with CD (N = 1430) and UC (N = 1059) included, majority were White (CD: 80.3%, UC: 78.3%), followed by African Americans (AA; CD: 10.5%, UC: 9.7%). Among patients with CD, AA were significantly less likely to adhere to biologics (adjusted OR [95%CI]: 0.61 [0.38; 0.99]) and more likely to discontinue biologics earlier (adjusted HR [95%CI]: 1.52 [1.16; 2.0]) during the follow-up period compared to Whites, after adjusting for other patient sociodemographic and clinical characteristics. Among patients with UC, no significant differences in the treatment adherence/persistence were observed between different races/ethnicities., Conclusions: Patients with CD were found to display racial differences in the treatment adherence and persistence of biologics, with significantly lower adherence and earlier discontinuation in AA compared to Whites. Such differences were not observed in patients with UC. Future studies are warranted to understand the possible reasons for racial differences, particularly in patients with CD., (© 2022. © Janssen Pharmaceuticals under exclusive licence to BioMed Central Ltd.

Introduction: The treatment of multiple myeloma (MM) remains a challenge as patients eventually progress through several lines of therapy (LOTs), requiring use of multiple MM drug classes. In this retrospective US claims-database study, we examined the healthcare costs of patients with MM who received ≥ 4 prior LOTs, including triple-class exposure (TCE)., Methods: Adult patients with MM were selected from the IBM MarketScan Commercial and Medicare claims databases (1 January 2012-30 June 2021). Eligible patients were required to have received at least four prior LOTs, and TCE (i.e., received a proteasome inhibitor, immunomodulatory drug, and anti-CD38-targeted monoclonal antibody) after the first-observed diagnosis of MM. The index date was defined as the initiation date of the first subsequent LOT after meeting the eligibility criteria for the study, and this date had to be after 1 January 2017 to capture contemporary cost estimates. The primary outcome measurements were all-cause and MM-related healthcare costs after the index date., Results: The study population included 68 patients with MM (63% men), with a mean age of 59.8 years. Mean duration from first-observed MM diagnosis until index date averaged 46.7 months. During a mean follow-up of 21.9 months, total all-cause healthcare costs averaged US$757,386 per patient (equivalent to US$34,610 per patient per month). MM-related healthcare costs (US$670,561 per patient) contributed on average 88.5% to the total all-cause healthcare costs; the majority (67.2%) of MM-related healthcare costs were attributed to drug and infusion costs (US$450,952 per patient)., Conclusions: In this retrospective US claims-database study, patients with MM with ≥ 4 prior LOTs, including TCE, continued to experience high healthcare costs that were mostly attributable to anti-myeloma drugs and their administration., (© 2022.

Aim: To evaluate among multiple myeloma (MM) patients, the proportions with first-line bortezomib/lenalidomide/dexamethasone (VRd) dose modifications and the associated baseline patient characteristics. Patients & methods: Adult MM patients treated with first-line VRd were selected from the Optum claims database. VRd dose modifications were defined based on lenalidomide dose. Results: Among 1497 MM patients, 33% received VRd lite and 22% VRd reduced. Compared with VRd regular, VRd lite usage was more likely to be associated with patients aged ≥75 years and female sex; VRd reduced usage was more likely to be associated with female sex and frailty. Conclusion: A large proportion of MM patients received VRd dose modifications in the real-world, which could potentially result in reduced effectiveness of VRd.

This study was conducted in patients treated for initial venous thromboembolism (VTE) for approximately 6 months to enhance understanding of the risk factors to inform clinical decision-making about long-term anticoagulation therapy. This retrospective cohort study was conducted using a large administrative claims database in the United States. A Cox proportional hazards model was used to examine demographic and clinical characteristics associated with recurrent VTE. A total of 13 831 patients had an index VTE event, and recurrent VTE occurred in 844 (6.1%) of these patients over a median follow-up of 22.8 months. Baseline comorbidities of arrhythmia, congestive heart failure, and chronic kidney disease were significantly associated with recurrent VTE. During the period of anticoagulation treatment after the index VTE, use of antidepressants was associated with an increased risk of recurrent VTE, whereas use of antibiotics and major surgery were associated with a decreased risk. In the 6 months prior to index VTE, anti-inflammatory agents and major surgery were associated with a decreased risk of recurrent VTE. The type of index VTE was also significantly associated with recurrent VTE, with an increased risk observed in patients with pulmonary embolism (PE) alone or PE with deep vein thrombosis (DVT) versus DVT alone. This real-world analysis identified baseline comorbidities, medications, and index VTE type to be factors predictive of recurrent VTE among patients treated for index VTE for approximately 6 months. Consideration of these factors may assist in the identification of patients who may benefit from extended anticoagulant therapy., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)
