Economic evaluation of Work, Weight, and Wellness (3W), a 2-year randomized trial of a weight loss program delivered through Hawaii hotel worksites.
Business case analysis from hotel perspective. Program resources were micro-costed (2008 dollars). Program benefits were reduced medical costs, fewer absences, and higher productivity. Primary outcome was discounted 24-month net present value (NPV).
Control program cost $222K to implement over 24 months ($61 per participant), intervention program cost $1.12M ($334). Including overweight participants (body mass index >25), discounted control NPV was -$217K; -$1.1M for intervention program. Presenteeism improvement of 50% combined with baseline 10% productivity shortfall required to generate positive 24-month intervention NPV.
3W's positive clinical outcomes did not translate into immediate economic benefit for participating hotels, although modest cost savings were observed in the trial's second year.
对 Work, Weight, and Wellness(3W)进行经济评估,这是一项为期两年的减肥计划随机试验,通过夏威夷酒店工作场所进行。
从酒店角度进行商业案例分析。项目资源进行了微观成本核算(2008 年美元)。项目效益包括降低医疗成本、减少缺勤和提高生产力。主要结果是贴现 24 个月的净现值(NPV)。
控制组在 24 个月内实施成本为 222 万美元(每个参与者 61 美元),干预组成本为 1120 万美元(334 美元)。包括超重参与者(身体质量指数>25),控制组的贴现净现值为-21.7 万美元;干预组为-110 万美元。如果要产生 24 个月干预 NPV 的正效益,需要将参与酒店的员工工作效率提高 50%,同时弥补基线 10%的生产力不足。
3W 的积极临床结果并未为参与酒店带来即时的经济效益,尽管在试验的第二年观察到适度的成本节约。
