Comparing post-operative resource consumption following transcatheter aortic valve implantation (TAVI) and conventional aortic valve replacement in the UK

Objective:

To define the in-hospital and 6-month post-discharge resource use, following Transcatheter Aortic Valve Implantation (TAVI) and conventional Aortic Valve Replacement (AVR) surgery within a single UK hospital.

Methods:

A local service evaluation of patients undergoing TAVI or AVR between January 2011 and May 2012 captured data until 6-months post-procedure, collected from hospital records and via a General Practitioner questionnaire. The main end-points were mortality, time in ITU/HDU, hospital length of stay (LoS), discharge destination, re-admission, and post-discharge primary/secondary care resource use. Sub-group analyses were performed for AVR patients aged ≥80 (AVR?≥?80) and with EuroSCORE of ≥10 (AVR ES?≥?10) to allow more direct comparison with ‘TAVI type’ patients.

Results:

Results are given as means (standard deviation) for TAVI (n?=?51), AVR (n?=?188), AVR?≥?80 (n?=?48), and AVR ES?≥?10 (n?=?47), respectively, unless otherwise stated. Age in years was 83.0 (8.1), 71.2 (13.1), 84.1 (2.7), 79.4 (7.1); EuroSCORE was 24.7 (11.9), 8.1 (6.4), 12.0 (6.0), and 16.5 (6.6); post-operative LoS (days) was 11.5 (11.2), 10.9 (10.8), 14.3 (16.7), and 15.2 (17.7). For discharged patients, 0%, 7%, 13%, and 9% had unplanned cardiac-related re-admissions within 30-days of discharge. Time to first readmission was 74.6 (34.0), 35.0 (34.2), 20.8 (9.7), and 22.6 (14.3) days.

Limitations:

This was a single-center retrospective evaluation, not prospectively powered to confirm differences in outcomes.

Conclusions:

Despite TAVI being performed in an older, higher risk population, LoS was similar to AVR. Most strikingly there were no cardiac-related re-admissions within 30-days for TAVI and time to first re-admission was significantly longer. This evaluation suggests that TAVI is clinically appropriate and provides economic advantages in both the hospital and post-discharge setting in this high risk group. Many patients undergoing TAVI are considered unfit for surgery and, hence, TAVI offers a treatment that delivers similar results to traditional AVR without the high risk associated with surgery.     

新型个人信息保护体系构建研究

大数据时代,传统的以“信息收集”规制为着力点的个人信息保护出现适法性困境,以“知情同意”为框架的机理失灵,个人信息的利用对象从直接个人信息逐渐向间接个人信息过渡,其财产价值凸显,新型个人信息财产权呼之欲出。立法应顺应数字经济的发展,构建合理新型个人信息体系。具体而言:纵向层面,以“宽进+删除权”为具体保护策略;横向层面,在信息主体和信息产业者之间合理配置权利,即信息主体享有个人信息权和个人信息财产权,信息产业者享有信息资产权。

Normal utilization rate in the Sraffa framework

This paper deals with the normal utilization rate in the Sraffa framework. It further presents two arguments about the utilization controversy surrounding the neo-Kaleckian theory of growth and distribution: First, it shows that the normal utilization rate is generally not independent of demand and the growth rate, and this result does not rely on the neo-classical production function and other restrictive assumptions. Second, it argues that endogenizing the normal utilization rate is not a general solution for the utilization controversy.

The role of inventories and capacity utilization as shock absorbers

We examine the role of inventories and capacity utilization (of both capital and labor) for the propagation of business cycle fluctuations. We document a new set of facts regarding the U.S. cyclical regularities of inventories and capacity utilization. First, we find that capital utilization and the flows of services from both capital and labor are procyclical, and comove with the holdings of inventories. Second, we find that labor utilization is procyclical as well, but is weakly negatively correlated with inventories. We build a model that accounts for these facts, and also accounts for the stylized inventory facts, i.e., inventory holdings are procyclical, while the inventory-to-sales ratio is countercyclical. The analysis is centered on the effects of two possible shocks: preference (demand) shocks and technology shocks. Our model shows that inventories and the rate of capital utilization are mostly complements, while inventories and the rate of labor utilization are mostly substitutes. It further shows that temporary demand shocks emphasize the role of inventories as being a “shock absorber,” whereas high-persistence demand shocks, as well as technology shocks of any persistence, emphasize the role of inventories as being a complement to consumption.

社会医疗保险对老人临终医疗服务利用的影响

本文利用2002-2014年CLHLS死亡人口数据,借助样本选择模型、两部分模型和bootstrap中介效应检验方法,首次比较全面深入地分析了社会医疗保险对老人临终总医疗费用支出和自负医疗费用支出的影响。研究发现,我国社会医疗保险既显著提高了老人临终医疗服务利用,也显著降低了自负水平。不同类型的社会医疗保险对临终医疗服务利用影响存在差异,医疗保险类型对临终医疗服务利用具有直接效应,医疗保险水平发挥了中介作用。医疗保险覆盖率在死亡年份影响临终医疗服务利用中发挥了中介作用。我国应该通过实行健康老龄化战略、加强死亡教育、发展临终关怀和完善医保监管等措施控制临终医疗支出增长以促进医疗保险可持续发展,并提升临终老人生存和死亡质量。
