BACKGROUND: Chronic kidney disease (CKD) is one of the most common complications of type 2 diabetes mellitus (T2D) and results in considerable economic burden. Current studies describing cost and health care resource utilization (HCRU) in T2D patients with CKD in real-world data are few. Even more scarce is evidence that takes into account disease severity and other comorbidities. OBJECTIVES: To (a) describe T2D patients with CKD identified in U.S. administrative claims data using laboratory test results for kidney function that are considered the gold standard criteria for kidney disease diagnosis and (b) estimate the annual HCRU and costs among these patients, overall and by disease severity and comorbidity subgroup.
METHODS:Optum CDM data between the years 2008 and 2017 were used to identify T2D patients with newly recognized CKD, using laboratory test results for estimated glomerular filtration rate (eGFR) or urine albumin-to-creatinine ratio (UACR). The study estimated annualized total, inpatient, What is already known about this subject• Type 2 diabetes (TD2) is associated with a significant economic burden, exacerbated by costs incurred by complications and common comorbidities that include chronic kidney disease (CKD), anemia, and cardiovascular disease.
Several comparative real-world effectiveness studies on direct oral anticoagulants (DOACs) have been conducted, but an overview of the available evidence remains to be developed, which could provide a better understanding of the value of DOACs relative to vitamin K antagonists (VKAs). Areas covered: A systematic literature review was conducted on the available real-world evidence (RWE) of three DOACs (rivaroxaban, dabigatran, and apixaban) compared with VKAs (e.g. warfarin), in patients with nonvalvular atrial fibrillation (NVAF).This systematic literature review included RWE published up to December 2016. Studies with > 50 patients reporting on incident and prevalent NVAF cases were included. The following databases were searched: Medline, Embase, and the Cochrane Library. Outcomes of interest included thromboembolic events, all-cause mortality, bleeding events, and nonpersistence. Of the 562 RWE DOACs articles retrieved, 49 presented results for rivaroxaban versus VKAs, 79 for dabigatran versus VKAs, and 18 for apixaban versus VKAs. Substantial heterogeneity was found across patient population, outcome definition, and follow-up period. Major bleeding, ischemic stroke, and intracranial hemorrhage were the most frequent outcomes analyzed. Expert commentary: Overall, the RWE studies were aligned with the Phase 3 trials. However, conflicting results were reported for several outcomes of interest.
EssentialsVitamin K antagonists (VKA) in venous thromboembolism (VTE) lower the risk of recurrences. 41 841 VKA-treated VTE patients had 1242 recurrent VTEs on therapy or early after cessation. An increased risk of recurrence was found in the first 120 days after VKA cessation. Patient education for the early detection of recurrent VTE after VKA cessation is recommended.Summary. Background: The standard treatment for venous thromboembolism (VTE) and the prevention of recurrent VTE (rVTE) consists of anticoagulant therapy. The optimal duration of anticoagulation depends on the presence of risk factors for rVTE. Objectives: To estimate the risk of rVTE in association with time since discontinuation of vitamin K antagonist (VKA) treatment. Methods: From the UK Clinical Practice Research Datalink with linked information on hospitalization and cause of death, a cohort of patients with a first VTE receiving initial VKA treatment between 2001 and 2013 was formed. With a nested case-control approach, patients with incident rVTE (cases) were matched to patients with VTE but without rVTE (controls). Adjusted rate ratios (RRs) of rVTE associated with time since VKA discontinuation relative to current VKA use were estimated from conditional logistic regression. Results: The VTE cohort comprised 41 841 patients with 1242 rVTEs and 6205 matched controls. The RR of rVTE was increased within 60 days following VKA discontinuation (RR 2.23, 95% confidence interval [CI] 1.71-2.91) and within 61-120 days following VKA discontinuation (RR 1.49, 95% CI 1.08-2.05) relative to current VKA use. The increased RR corresponded to excess incidence rates of 6.72 (95% CI 3.90-10.06) rVTE cases per 100 personyears within 60 days, and of 2.68 (95% CI 0.42-5.58) rVTE cases per 100 person-years within 61-120 days after VKA discontinuation. Conclusions: VKA discontinuation results in a transient increased risk of rVTE, which peaks within 60 days and lasts for up to 120 days after VKA discontinuation. Specific patient education for increased vigilance for signs and symptoms of recurrences is recommended in this period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
