营销渠道中的制度环境

以往的营销渠道研究都是从以效率为基础的任务环境出发,在很大程度上忽略了从以合法性为基础的制度环境出发对渠道治理过程进行研究。本文指出制度以及制度化过程对渠道治理策略形成的影响,并提出一个综合性概念框架,将新制度理论融入现有的营销渠道研究中来。作者应用新制度理论,提出制度化过程和三种治理机制以弥补现有的任务环境视角方法的不足,并指出可以从合法性和效率两个方面来衡量渠道成员的持续竞争优势。还指出持续性的竞争优势可通过合法性与效率两方面予以测度。     

CT三维仿真成像技术在输尿管膀胱的临床应用

目的探讨输尿管膀胱疾病采取CT三维仿真成像技术的临床应用价值。方法通过静脉注入碘海醇造影剂,将泌尿系完全充盈后,取螺旋CT薄层扫描原始图像,并将其数据传输到工作站中,进行图像后期处理,取得多种三维立体和仿真内镜图像。结果输尿管膀胱疾病包括膀胱肿瘤、前列腺增生、输尿管狭窄以及神经源性膀胱伴有输尿管扩张,依次为6例、9例、5例、2例。另外,纤维膀胱肿瘤6例,前列腺增生6例及输尿管狭窄4例。结论输尿管膀胱疾病采取CT三维仿真成像技术,可将各种病理形态改变完全显示出来,对制订临床治疗方案和评估预后起到非常关键的作用。

Asymptotically Optimal Response‐Adaptive Designs for Allocating the Best Treatment: An Overview

Response‐adaptive designs are being used increasingly in applications, and this is especially so in early phase clinical trials. This paper reviews a particular class of response‐adaptive designs that have the property of picking the superior treatment with probability tending to one. This is a desirable property from an ethical point of view in clinical trials. The model underlying such designs is a randomly reinforced urn. This paper provides an overview of results for these designs, starting from the early paper of Durham and Yu (1990) until the recent work by Flournoy, May, Moler and Plo (2010).     

Clinical and economic benefit of enzymatic debridement of pressure ulcers compared to autolytic debridement with a hydrogel dressing

Abstract

Objective:

The purpose of this study was to determine the cost-effectiveness of enzymatic debridement using collagenase relative to autolytic debridement with a hydrogel dressing for the treatment of pressure ulcers.

Methods:

A 3-stage Markov model was used to determine the expected costs and outcomes of wound care for collagenase and hydrogel dressings. Outcome data used in the analysis were taken from a randomized clinical trial that directly compared collagenase and hydrogel dressings. The primary outcome in the clinical trial was the proportion of patients achieving a closed epithelialized wound. Transition probabilities for the Markov states were estimated from the clinical trial. A 1-year time horizon was used to determine the expected number of closed wound days and the expected costs for the two alternative debridement therapies. Resource utilization was based on the wound care treatment regimen used in the clinical trial. Resource costs were derived from standard cost references and medical supply wholesalers. The economic perspective taken was that of the long-term care facility. No cost discounting was performed due to the short time horizon of the analysis. A deterministic sensitivity analysis was conducted to analyze economic uncertainty.

Results:

The number of expected wound days for the collagenase and hydrogel cohorts are estimated at 48 and 147, respectively. The expected direct cost per patient for pressure ulcer care was $2003 for collagenase and $5480 for hydrogel debridement. The number of closed wound days was 1.5-times higher for collagenase (317 vs 218 days) than with the hydrogel. The estimated cost/closed wound day was 4-times higher for the hydrogel ($25) vs collagenase ($6).

Conclusions:

In this Markov model based on a randomized trial of pressure ulcer care in a long-term care setting collagenase debridement was economically dominant over autolytic debridement, yielding better outcomes at a lower total cost. Since it was a single institution study with a small sample size, the results should be interpreted with caution. Specifically, the findings may not necessarily be generalized to other hydrogel dressings, healthcare settings, age groups, or to wounds of other etiologies.
