Objective: To assess the cost-effectiveness of exenatide 2?mg once-weekly (EQW) compared to dulaglutide 1.5?mg QW, liraglutide 1.2?mg and 1.8?mg once-daily (QD), and lixisenatide 20?μg QD for the treatment of adult patients with type 2 diabetes mellitus (T2DM) not adequately controlled on metformin.

Methods: The Cardiff Diabetes Model was applied to evaluate cost-effectiveness, with treatment effects sourced from a network meta-analysis. Quality-adjusted life years (QALYs) were calculated with health-state utilities applied to T2DM-related complications, weight changes, hypoglycemia, and nausea. Costs (GBP £) included drug treatment, T2DM-related complications, severe hypoglycemia, nausea, and treatment discontinuation due to adverse events. A 40-year time horizon was used.

Results: In all base-case comparisons, EQW was associated with a QALY gain per patient; 0.046 vs dulaglutide 1.5?mg; 0.102 vs liraglutide 1.2?mg; 0.043 vs liraglutide 1.8?mg; and 0.074 vs lixisenatide 20?μg. Cost per patient was lower for EQW than for liraglutide 1.8?mg (?£2,085); therefore, EQW dominated liraglutide 1.8?mg. The cost difference per patient between EQW and dulaglutide 1.5?mg, EQW and liraglutide 1.2?mg, and EQW and lixisenatide 20?μg was £27, £103, and £738, respectively. Cost per QALY gained with EQW vs dulaglutide 1.5?mg, EQW vs liraglutide 1.2?mg, and EQW vs lixisenatide 20?μg was £596, £1,004, and £10,002, respectively. In the probabilistic sensitivity analysis, the probability that EQW is cost-effective ranged from 76–99%.

Conclusion: Results suggest that exenatide 2?mg once-weekly is cost-effective over a lifetime horizon compared to dulaglutide 1.5?mg QW, liraglutide 1.2?mg QD, liraglutide 1.8?mg QD, and lixisenatide 20?μg QD for the treatment of T2DM in adults not adequately controlled on metformin alone.  相似文献

Aims: Data highlighting the cost drivers for non-valvular atrial fibrillation (NVAF) patients in terms of vitamin K antagonist (VKA) treatment and monitoring are lacking in France. This study aimed to evaluate the real-life daily cost of VKA treatment in 2013, in French patients suffering from NVAF.

Methods: This longitudinal observational study was performed using the EGB (Echantillon Généraliste des Bénéficiaires) database, a random sample of the French national insurance (NHI) database, which covers 80% of the population. All adult patients whose first NVAF anticoagulant treatment in 2013 was a VKA were analyzed. Costs were calculated for the duration of follow-up and then divided by the number of days of therapy. The analysis was performed both from the French NHI perspective (amount reimbursed by the NHI) and from a collective perspective.

Results: In this study, 3,254 NVAF patients treated with VKA in 2013 were included, and this sample comprised 52.6% males. The mean daily cost of VKA treatment was €1.13 (±1.18) according to the collective perspective (89.4% of this cost was associated to INR measurement) and €1.05 (±1.16) according to the NHI perspective.

Limitations: As diagnoses associated with procedures are not available in the EGB database, proxies were used, and an algorithm was created to define the AF population.

Conclusions: This analysis is the first to consider an exhaustive spectrum of the costs of VKA treatment in France using EGB data. VKA medication requires exhaustive follow-up, and, thus, associated costs are important. The results of the present study confirmed this close follow-up for VKA patients, making the cost of treatment by VKA nearly 10-times more expensive than the cost of medication itself.  相似文献

Background:

Venous thromboembolism (VTE), comprised of deep vein thrombosis (DVT) and pulmonary embolism (PE), is commonly treated with a low-molecular-weight heparin such as enoxaparin plus a vitamin K antagonist (VKA) to prevent recurrence. Administration of enoxaparin?+?VKA is hampered by complexities of laboratory monitoring and frequent dose adjustments. Rivaroxaban, an orally administered anticoagulant, has been compared with enoxaparin?+?VKA in the EINSTEIN trials. The objective was to evaluate the cost-effectiveness of rivaroxaban compared with enoxaparin?+?VKA as anticoagulation treatment for acute, symptomatic, objectively-confirmed DVT or PE.

Methods:

A Markov model was built to evaluate the costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios associated with rivaroxaban compared to enoxaparin?+?VKA in adult patients treated for acute DVT or PE. All patients entered the model in the ‘on-treatment’ state upon commencement of oral rivaroxaban or enoxaparin?+?VKA for 3, 6, or 12 months. Transition probabilities were obtained from the EINSTEIN trials during treatment and published literature after treatment. A 3-month cycle length, US payer perspective ($2012), 5-year time horizon and a 3% annual discount rate were used.

Results:

Treatment with rivaroxaban cost $2,448 per-patient less and was associated with 0.0058 more QALYs compared with enoxaparin?+?VKA, making it a dominant economic strategy. Upon one-way sensitivity analysis, the model’s results were sensitive to the reduction in index VTE hospitalization length-of-stay associated with rivaroxaban compared with enoxaparin?+?VKA. At a willingness-to-pay threshold of $50,000/QALY, probabilistic sensitivity analysis showed rivaroxaban to be cost-effective compared with enoxaparin?+?VKA approximately 76% of the time.

Limitations:

The model did not account for the benefits associated with an oral and minimally invasive administration of rivaroxaban. ‘Real-world’ applicability is limited because data from the EINSTEIN trials were used in the model. Also, resource utilization and costs were based on the US healthcare system.

Conclusion:

Rivaroxaban is a cost-effective option for anticoagulation treatment of acute VTE patients.  相似文献

Abstract

Objectives:

This study evaluated patient and prescriber characteristics, treatment patterns, average daily dose (ADD), and glycemic control of patients initiating glucagon-like peptide 1 (GLP-1) receptor agonists in Germany.

Methods:

The LifeLink? EMR-EU database was searched to identify patients initiating exenatide twice daily (BID) or liraglutide once daily (QD) during the index period (January 1, 2009–April 4, 2010). Eligible patients had ≥180 days pre-index history, ≥90 days post-index follow-up, and a pre-index type 2 diabetes diagnosis. Univariate tests were conducted at α?=?0.05.

Results:

Six hundred and ninety-two patients were included (exenatide BID 292, liraglutide QD 400): mean (SD) age 59 (10) years, 59% male. Diabetologists prescribed liraglutide QD to a larger share of patients (65% vs 35% exenatide BID) than non-diabetologists (51% vs 49%). GLP-1 receptor agonist choice was not associated with age (p?=?0.282), gender (p?=?0.960), number of pre-index glucose-lowering medications (2.0 [0.9], p?=?0.159), pre-index HbA1c (8.2 [1.5%], p?=?0.231) or Charlson Comorbidity Index score (0.45 [0.78], p?=?0.547). Mean (SD) ADD was 16.7?mcg (9.2, label range 10–20?mcg) for exenatide BID and 1.4?mg (0.7, label range 0.6–1.8?mg) for liraglutide QD. Among patients with post-index HbA1c tests, mean unadjusted values did not differ between cohorts. Exenatide BID patients were more likely than liraglutide QD patients to continue pre-index glucose-lowering medications (67.1% vs 60.3%, p?=?0.027) or to start concomitant glucose-lowering medications at index (32.2% vs 25.0%, p?=?0.013); exenatide BID patients were less likely to augment treatment with another drug post-index (15.8% vs 22.5%, p?=?0.027).

Limitations:

Results may not be generalizable. Lab measures for clinical outcomes were available only for a sub-set of patients.

Conclusions:

Results suggested that some differences exist between patients initiating exenatide BID or liraglutide QD, with respect to prescribing physician specialty and pre- and post-index treatment patterns. Both GLP-1 receptor agonists showed comparable post-index HbA1c values in a sub-set of patients.  相似文献

Abstract

Objective: To describe the incidence of diagnosis of gastroesophageal reflux disease and acid-related conditions (GERD/ARC) throughout childhood and characterize patterns of diagnosis and treatment with proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs).

Methods: Cohorts of GERD/ARC children (age 0–18 years) were identified from a large US administrative claims database covering 1999–2005 using ICD-9 codes. Incidence, healthcare utilization (HCU), costs, therapy discontinuation and switching rates were compared between various age and patient groups.

Results: Between 2000 and 2005 annual incidence of GERD/ARC diagnosis among infants (age ≤1 year) more than tripled (from 3.4 to 12.3%) and increased by 30% to 50% in other age groups. Patients diagnosed by GI specialists (9.2%) were more likely to be treated with PPIs compared to patients diagnosed by primary care physician (PCP). PPI-initiated patients doubled (from 31.5% in 1999 to 62.6% in 2005) and, when compared with H2RA-initiated patients, were associated with 30% less discontinuation and 90% less therapy switching in the first month, and with higher comorbidity burden and pre-treatment total HCU and costs when diagnosed by GI specialists.

Limitations: The use of an exploratory definition for GERD/ARC, administrative claims data and potential coding errors in diagnosis codes used in selection process may limit the generalizability of the results.

Conclusions: GERD/ARC incidence increased for children of all ages between 2000 and 2005. PCPs made the majority of diagnoses. PPI initiations have now surpassed H2RA initiations.  相似文献

According to its advertisement copy, ‘Independence Day' delivers the ultimate encounter when powerful aliens launch an invasion against the human race. Does this ‘ultimate encounter' simply retrace the old fashioned Hollywood theme of good versus evil? Or is there a more sinister meaning woven into the text of the film? This paper deconstructs the narrative of the film to reveal the underlying monolithic, Americanised modernity and argues that ‘Independence Day' provides an allegorical legitimation for Pax Americana.  相似文献
