Cost–consequence analysis of a hemostatic matrix alone or in combination for spine surgery patients

Background: A five-year retrospective database analysis comparing the use of Floseal¹ flowable topical hemostat alone (F) and in combination with gelatin/thrombin (F?+?G/T) to achieve hemostasis and control surgical bleeding showed higher resource utilization for F?+?G/T cases relative to F matched pairs during spinal surgery. Lower resource use in the F group was characterized by shorter hospital length of stay and surgical time as well as fewer blood transfusions and less hemostat agent used per surgery.

Objective: To evaluate the cost–consequence of using F compared to F?+?G/T in minor, major and severe spinal surgery from the US hospital perspective.

Methods: A cost–consequence model was developed using the US hospital perspective. Model inputs include clinical inputs from the literature, cost inputs (hemostatic matrices, blood product transfusion, hospital stay and operating room time) from the literature, and an analysis of annual spine surgery volume (minor, major and severe) using the 2012 National Inpatient Sample (NIS) database. Costs are reported in 2017?US dollars. One-way and probabilistic sensitivity analyses address sources of variability in the results.

Results: A medium-volume hospital (130 spine surgeries per year) using F versus F?+?G/T for spine surgeries is expected to require 85 less hours of surgical time, 58 fewer hospital days and 7 fewer blood transfusions in addition to hemostat volume savings (F: 1?mL, thrombin: 1994?mL). The cost savings associated with the hospital resources for a medium-volume hospital are expected to be $317,959 (surgical hours?=?$154,746, hospital days?=?$125,237, blood transfusions?=?$19,023, hemostatic agents?=?$18,953) or $2445 per spine surgery.

Conclusions: The use of F versus F?+?G/T could lead to annual cost savings for US hospitals performing a low to high volume of spinal surgeries per year.

Spousal Wealth and Fathers’ Involvement in Childcare in Uganda

ABSTRACT

The redistribution of household work is considered essential for effectively empowering women. This study examines the extent to which fathers’ evaluation of their wealth in relation to their wives’ influences fathers’ willingness to participate in childcare, a domain traditionally gender ascribed to wives. Data were gathered from a mothers’ survey and a fathers’ survey, each with a sample of 200, conducted in a rural and an urban district in Uganda in 2008. The study compares mean scores for perception and practice indices across three wealth categories: “wife is wealthier than husband,” “husband is wealthier than wife,” and “shared or equal wealth.” Data show that fathers are more likely to engage in childcare when husbands and wives share or have equal wealth than when there are wealth differences between spouses. The results suggest that policy should focus on raising women's economic endowment as well as public education that encourages progressive perceptions of gender roles.     

美国奥巴马总统“气候行动计划”解读

2013年6月,美国总统奥巴马在华盛顿乔治城大学发表关于应对气候变化的讲话,发布了总统气候行动计划,重申到2020年美国实现在2005年基础上减排温室气体17%的承诺,并从减少温室气体排放、应对气候变化的不利影响和领导国际合作三个方面系统阐释了美国联邦政府将采取的一系列举措,这是迄今为止美国政府最全面综合的气候政策。通过分析和梳理该气候行动计划推出的背景、主要内容以及美国各界的反应等,指出了该计划的实质和存在的一些问题,包括在实施范围、执行力度、持续性和有效性等方面的局限性。

碳价冲击对我国制造业发展的影响分析——基于分行业面板数据的实证研究

碳市场形成的碳价格会影响制造业各分行业成本的变动,从而导致经济增长水平、能源消费量及要素市场价格的改变。采用2001-2011年中国制造业各行业GDP水平、碳排放量、能源消耗量、人力资本及物质资本等数据,以每吨60元碳价水平为基准测算碳价冲击对制造业总体及各分行业的影响。结果表明:碳价冲击有助于提高制造业整体的增长水平,减少生产过程中对能源要素的需求,并可能改变要素市场上各要素的相对价格。为进一步研究制造业不同行业的异质性,将27个目标行业划分为高碳行业和低碳行业,研究这两种不同类型的行业组在受到气候政策规制时对相关指标的影响。研究显示:无论是低碳行业还是高碳行业,碳减排政策都有助于提升产出水平,但对这两类行业能源消耗的影响不同,其中高碳行业在受到碳价冲击时会增加资本要素的投入水平,以替代原有的能源要素需求;而低碳行业并没有显著减少对能源要素的需求。
