Objectives:
A new rechargeable dual-channel deep brain stimulation (DBS) system has been introduced for the treatment of Parkinson's disease and other movement disorders. However, the clinical value of the device, which has a high cost, remains unclear.
Materials And Methods:
We conducted a cost-minimization analysis using a national database of health insurance claims in Japan. DBS-related costs were compared between rechargeable and non-rechargeable devices and estimated across a 20-year period.
Results:
Although the price of rechargeable DBS was higher than that of non-rechargeable DBS, we observed total cost-savings of 8.4 million yen across 20 years by considering costs related to implantation surgery, frequency of replacement, and risk of complications.
Conclusions:
In this study, real-world evidence indicated that rechargeable dual-channel DBS is a reasonable choice for saving total medical costs. Price revisions should consider cost-effectiveness findings for medical devices.

01:11Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...

The AACN emphasizes a healthy work environment through six standards to achieve an optimal patient outcome. The standards are appropriate staffing, meaningful recognition, collaboration, authentic leadership, effective communication, and decision-making. In addition, AACN provides certification programs, webinars, journals, and...
01:24Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
01:19Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...
01:21Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
