Outcomes of adding second hypoglycemic drug after metformin monotherapy failure among type 2 diabetes in Hungary

<p>Abstract</p> <p>Aim</p> <p>The objective of this observational study was to assess the status of glycemic control and associated patient-reported outcomes in ambulatory Hungarian patients with type 2 diabetes mellitus (T2DM) who were prescribed either a sulfonylurea (SU) or a thiazolidinedione (TZD) in addition to the prior metformin (MF) monotherapy.</p> <p>Methods</p> <p>Type 2 diabetics aged ≥ 30 years and who had added an SU or TZD to previous MF monotherapy at least 1 year prior to the visit date were identified during January 2006 to March 2007. Information on HbA1c (A1C), medication use and co-morbid conditions was extracted from the medical record up to 6 months prior to the addition of SU or TZD to MF (baseline), and a minimum of one year after the initiation of either SU or TZD. Glycemic control (A1C < 6.5%) was assessed using the last available A1C value in the medical record. Self-reported hypoglycemia, health-related quality of life (HRQoL) and treatment satisfaction were also assessed.</p> <p>Results</p> <p>A total of 414 patients (82% SU+MF and 18% TZD+MF) with a mean age of 60.5 years (SD = 9.4 years) participated in the study. About 27% of patients reported hypoglycemic episodes, with about one-third reporting episodes that resulted into interruption of activities or required medical/non-medical assistance. Three quarters of patients were not at glycemic goal and BMI was the only factor significantly associated with failure to have an A1C level < 6.5%. Patients' HRQoL was significantly associated with self-reported hypoglycemic episodes (p = 0.017), and duration of diabetes (p = 0.045).</p> <p>Conclusion</p> <p>Nearly 75% of patients were not at A1C goal of < 6.5% despite using two oral anti-hyperglycemic medications. Approximately 9% of patients reporting hypoglycemia required some kind of medical/non-medical assistance. Greater BMI at baseline was associated with an A1C level ≥ 6.5%. Finally, self- reports of hypoglycemia and duration of diabetes were associated with low HRQoL.</p

Real-world outcomes among US Merkel cell carcinoma patients initiating immune checkpoint inhibitors or chemotherapy.

Aim: Retrospectively assessed treatment patterns and clinical and economic outcomes in Merkel cell carcinoma (MCC) patients receiving recommended first-line regimens. Materials & methods: MCC patients newly treated with either immune checkpoint inhibitors (ICIs) or chemotherapies (CTs) were selected from the Veterans Health Administration database (2013–2018); 74 patients (ICIs: 20 and CTs: 54) were selected. Results: Median duration of therapy was 300 days for ICIs and 91 days for CTs. Time to next treatment was 245 and 184 days, respectively. Mean total (per patient per month) costs were $15,306 (ICIs) and$10,957 (CTs), of which 51% and 86%, respectively, were non-MCC therapy-related costs. Conclusion: Despite higher costs, utilization of ICIs in first-line MCC shows clinical advantages over CTs in the real world

Cost-effectiveness Analysis of Apixaban against Warfarin for Stroke Prevention in Patients with Nonvalvular Atrial Fibrillation in Japan

Abstract Purpose The aim of this study was to evaluate the cost-effectiveness of apixaban compared with to warfarin, current standard of care, for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF) in Japan. Methods A previously published lifetime Markov model was adapted to evaluate the cost-effectiveness of apixaban compared with warfarin in patients with NVAF in Japan. In the same model, the costs associated with each clinical event and background mortality were replaced with Japanese data. Whenever available, some of the utility parameters were derived from Japanese published literature. Lifetime horizon was selected to evaluate the value of the treatment benefit (stroke prevention) against potential risks (such as major bleedings) among patients with NVAF. Direct medical cost, long-term care cost, and quality-adjusted life years (QALYs) were calculated from the payers' perspective. Findings Compared with warfarin, treatment with apixaban was estimated to increase life expectancy by 0.231 year or 0.240 QALYs while treatment cost increased by ¥511,692 (US $5117 at an exchange rate of US$1 = ¥100). The incremental cost-effectiveness ratio was ¥2,135,743 per QALY (US $21,357 per QALY). On the basis of the results of the probabilistic sensitivity analysis, when the willingness-to-pay threshold was set at approximately ≥¥2,250,000 (US$22,500) per QALY, the probability of apixaban being cost-effective was ≥50%. Assuming a willingness-to-pay threshold of ¥5,000,000 (US $50,000) and ¥6,700,000 (US$67,000) in Japan, the probability of apixaban being cost-effective was 85% and 91%, respectively. Conclusion Although most participants in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial used for the efficacy data of apixaban in the model were non-Japanese patients, the impact of the limitations on our results was considered small, and our results were deemed robust because of the additional effect in Japanese patients compared with that in the global population according to the subanalysis of Japanese patients in the trial. Therefore, based on an adaptation of a published Markov model, apixaban is a cost-effective alternative to warfarin in Japan for stroke prevention among patients with NVAF

Real-world comparison of bleeding risks among non-valvular atrial fibrillation patients prescribed apixaban, dabigatran, or rivaroxaban

Limited real-world data are available regarding the comparative safety of non-vitamin K antagonist oral anticoagulants (NOACs). The objective of this retrospective claims observational cohort study was to compare the risk of bleeding among non-valvular atrial fibrillation (NVAF) patients prescribed apixaban, dabigatran, or rivaroxaban. NVAF patients aged ≥18 years with a 1-year baseline period were included if they were new initiators of NOACs or switched from warfarin to a NOAC. Cox proportional hazards modelling was used to estimate the adjusted hazard ratios of any bleeding, clinically relevant non-major (CRNM) bleeding, and major inpatient bleeding within 6 months of treatment initiation for rivaroxaban and dabigatran compared to apixaban. Among 60,227 eligible patients, 8,785 were prescribed apixaban, 20,963 dabigatran, and 30,529 rivaroxaban. Compared to dabigatran or rivaroxaban patients, apixaban patients were more likely to have greater proportions of baseline comorbidities and higher CHA2DS2-VASc and HAS-BLED scores. After adjusting for baseline clinical and demographic characteristics, patients prescribed rivaroxaban were more likely to experience any bleeding (HR: 1.35, 95% confidence interval [CI]: 1.26-1.45), CRNM bleeding (HR: 1.38, 95% CI: 1.27-1.49), and major inpatient bleeding (HR: 1.43, 95% CI: 1.17-1.74), compared to patients prescribed apixaban. Dabigatran patients had similar bleeding risks as apixaban patients. In conclusion, NVAF patients treated with rivaroxaban appeared to have an increased risk of any bleeding, CRNM bleeding, and major inpatient bleeding, compared to apixaban patients. There was no significant difference in any bleeding, CRNM bleeding, or inpatient major bleeding risks between patients treated with dabigatran and apixaban

RHYTHM-AF: design of an international registry on cardioversion of atrial fibrillation and characteristics of participating centers

BACKGROUND Atrial fibrillation is a serious public health problem posing a considerable burden to not only patients, but the healthcare environment due to high rates of morbidity, mortality, and medical resource utilization. There are limited data on the variation in treatment practice patterns across different countries, healthcare settings and the associated health outcomes. METHODS/DESIGN RHYTHM-AF was a prospective observational multinational study of management of recent onset atrial fibrillation patients considered for cardioversion designed to collect data on international treatment patterns and short term outcomes related to cardioversion. We present data collected in 10 countries between May 2010 and June 2011. Enrollment was ongoing in Italy and Brazil at the time of data analysis. Data were collected at the time of atrial fibrillation episode in all countries (Australia, Brazil, France, Germany, Italy, Netherlands, Poland, Spain, Sweden, United Kingdom), and cumulative follow-up data were collected at day 60 (±10) in all but Spain. Information on center characteristics, enrollment data, patient demographics, detail of atrial fibrillation episode, medical history, diagnostic procedures, acute treatment of atrial fibrillation, discharge information and the follow-up data on major events and rehospitalizations up to day 60 were collected. DISCUSSIN A total of 3940 patients were enrolled from 175 acute care centers. 70.5% of the centers were either academic (44%) or teaching (26%) hospitals with an overall median capacity of 510 beds. The sites were mostly specialized with anticoagulation clinics (65.9%), heart failure (75.1%) and hypertension clinics (60.1%) available. The RHYTHM-AF registry will provide insight into regional variability of antiarrhythmic and antithrombotic treatment of atrial fibrillation, the appropriateness of such treatments with respect to outcomes, and their cost-efficacy. Observations will help inform strategies to improve cardiovascular outcomes in patients with atrial fibrillation.

Relationships between beliefs about medications and use of prescribed chronic medications

The purpose of this study was to assess associations between medication beliefs and medication adherence among users of prescribed chronic medications. Under a modified self-regulatory framework, medication adherence is considered as a coping strategy and medication beliefs as factors influencing medication adherence. Patients\u27 medication beliefs were assessed using the Beliefs about Medicines Questionnaire (BMQ) and medication non-adherence was assessed using the Morisky Medication Adherence Scale. Associations between medication beliefs and medication non-adherence were assessed using Pearson correlation and regression analysis. Strengths of associations between beliefs and non-adherence were compared across patients using a different number of chronic medications using Fisher-transformed Pearson correlation estimates and pairwise Tukey\u27s comparison test. Path analysis with latent variables was used to assess fit of the factor structure of associations between medication beliefs and medication non-adherence. Data were collected at outpatient pharmacy of a primary care clinic affiliated with a hospital in Indianapolis, IN. Study participants were sought from patients waiting to see their pharmacists. Eligibility criteria were continuous use of prescribed medications for at least two months prior to completion of the survey and ability to comfortably read and complete a survey in English. A response rate for this study was 78.3 percent. Specific necessity to use medications had a negative but insignificant association with medication non-adherence; whereas, specific concerns related to medications, perceived general overuse of medications by prescribers and general harmful nature of medications had significant positive associations with medication non-adherence. When relative strengths of associations between medication beliefs and non-adherence were assessed, only specific-necessity and specific-concerns exhibited significant associations with medication non-adherence. Strengths of associations between beliefs and non-adherence were similar across patients using different numbers of chronic medications, which indicated that the BMQ effectively assessed medication beliefs across patients using different number of chronic medications. Path analysis indicated that specific-necessity, specific-concerns and general-overuse were able to predict 26.3 percent of the variance in medication non-adherence. General-harm and specific-necessity accounted for 54.8 percent of variance in specific-concerns. Medication beliefs assessment can be used to detect problems related to medication use
