Chinese Herbal Medicines Might Improve the Long-Term Clinical Outcomes in Patients with Acute Coronary Syndrome after Percutaneous Coronary Intervention: Results of a Decision-Analytic Markov Model

Economic evaluation of deep brain stimulation compared with vagus nerve stimulation and usual care for patients with refractory epilepsy: A lifetime decision analytic model

OBJECTIVES

This study was undertaken to estimate the cost-effectiveness of deep brain stimulation (DBS) compared with vagus nerve stimulation (VNS) and care as usual (CAU) for adult patients with refractory epilepsy from a health care perspective using a lifetime decision analytic model.

METHODS

A Markov decision analytic model was constructed to estimate the lifetime cost-effectiveness of DBS compared with VNS and CAU. Transition probabilities were estimated from a randomized controlled trial, and assumptions were made in consensus with an expert panel. Primary outcomes were expressed as incremental costs per quality-adjusted life-year (QALY) and per responder. Univariate and probabilistic sensitivity analyses were conducted to characterize parameter uncertainty.

RESULTS

In DBS, 28.4% of the patients were responders, with an average of 21.38 QALYs per patient and expected lifetime health care costs of €187 791. VNS had fewer responders (22.3%), fewer QALYs (20.70), and lower lifetime costs (€156 871). CAU had the fewest responders (6.2%), fewest QALYs (18.74), and lowest total health care costs (€64 670). When comparing with CAU, incremental cost-effectiveness ratios (ICERs) showed that costs per QALY gained were slightly lower for DBS (€46 640) than for VNS (€47 155). When comparing DBS with VNS, an incremental cost per additional QALY gained of €45 170 was found for DBS. Sensitivity analyses showed that ICERs were heavily dependent on assumptions regarding loss to follow-up in the respective clinical trial.

SIGNIFICANCE

This study suggests that, given current limited evidence, VNS and DBS are potentially cost-effective treatment strategies compared to CAU for patients with refractory epilepsy. However, results for DBS were heavily impacted by assumptions made to extrapolate nonresponse from the original trial. More stringent assumptions regarding nonresponse resulted in an ICER just above an acceptable willingness to pay threshold. Given the uncertainty surrounding the effectiveness of DBS and the large impact of assumptions related to nonresponse, further empirical research is needed to reduce uncertainty.

Efficacy and safety of Shexiang Baoxin Pill combined with Western medicine in the treatment of acute myocardial infarction: A single-center, double-blind, randomized controlled trial

BACKGROUND

The morbidity and mortality of acute myocardial infarction are on the rise, and the efficacy of conventional treatment is limited. Shexiang Baoxin Pill is a kind of proprietary Chinese medicine, which has been widely used in the treatment of acute myocardial infarction in China, and has certain advantages. At present, there is a lack of strict randomized controlled trials to verify the efficacy and safety of Shexiang Baoxin Pill combined with Western medicine in the treatment of acute myocardial infarction. Therefore, the purpose of this randomized controlled trial is to evaluate the clinical efficacy of Shexiang Baoxin Pill combined with Western medicine in the treatment of acute myocardial infarction.

METHODS

This is a prospective randomized controlled trial to study the efficacy and safety of Shexiang Baoxin Pill combined with Western medicine in the treatment of acute myocardial infarction. It is approved by the Clinical Research Society of our hospital. According to 1:1, the patients will be randomly divided into observation group (Shexiang Baoxin Pill combined with Western medicine group) and control group (routine Western medicine group). The patients in the 2 groups will be treated continuously for 4 weeks and followed up for 3 months. Pay attention to its curative effect index and safety index. The observation indexes included total effective rate of improvement of cardiac function, left ventricular ejection fraction (LVEF), endothelin (ET), nitric oxide (NO) level, interleukin-6 (IL--6), adverse reactions, and so on. We will analyze the structure by SPSS version 19.0.

DISCUSSION

This study will evaluate the efficacy and safety of Shexiang Baoxin Pill combined with Western medicine in the treatment of acute myocardial infarction. The results of this experiment will provide clinical basis for Shexiang Baoxin Pill combined with Western medicine in the treatment of acute myocardial infarction.

Modelling the cost-effectiveness of person-centred care for patients with acute coronary syndrome

BACKGROUND

Person-centred care has been shown to be cost-effective compared to usual care for several diseases, including acute coronary syndrome, in a short-term time perspective (< 2 years). The cost-effectiveness of person-centred care in a longer time perspective is largely unknown.

OBJECTIVES

To estimate the mid-term cost-effectiveness of person-centred care compared to usual care for patients (< 65) with acute coronary syndrome, using a 2-year and a 5-year time perspective.

METHODS

The mid-term cost-effectiveness of person-centred care compared to usual care was estimated by projecting the outcomes observed in a randomized-controlled trial together with data from health registers and data from the scientific literature, 3 years beyond the 2-year follow-up, using the developed simulation model. Probabilistic sensitivity analyses were performed using Monte Carlo simulation.

RESULTS

Person-centred care entails lower costs and improved effectiveness as compared to usual care, for a 2-year time and a 5-year perspective. Monte Carlo simulations suggest that the likelihoods of the person-centred care being cost-effective compared to usual care were between 80 and 99% and between 75 and 90% for a 2-year and a 5-year time perspective (using a 500,000 SEK/QALY willingness-to-pay threshold).

CONCLUSIONS

Person-centred care was less costly and more effective compared to usual care in a 2-year and a 5-year time perspective for patients with acute coronary syndrome under the age of 65.
