The objective of this study was to determine the economic impact of the Hawaii Medical Service Association's health promotion/disease prevention program. A retrospective analysis of health risk, health claims, and cost was performed using a mixed model factorial design for the years 2002-2005 that compared program participants to nonparticipants. All analyses were adjusted for preexisting observed differences based on sex, age, baseline morbidity, and health care costs between participants and nonparticipants using propensity score matching method and/or covariates as appropriate. After analyzing data from more than 166,000 HMSA members over a 4-year period, participants were found to incur consistently lower costs. Predictive modeling of upward cost trajectories relative to actual health care costs for participants and risk-matched nonparticipants indicated a savings of $350 per participant per year. Those who participated in additional wellness programming demonstrated additional cost savings. This study illustrates the economic value of a comprehensive health promotion program.
本研究旨在确定夏威夷医疗服务协会（Hawaii Medical Service Association，HMSA）健康促进/疾病预防计划的经济影响。采用 2002 年至 2005 年的混合模型析因设计，对健康风险、健康索赔和成本进行回顾性分析，将参与者与非参与者进行比较。所有分析均根据参与者和非参与者之间存在的性别、年龄、基线发病率和医疗费用等预先观察到的差异进行调整，使用倾向评分匹配方法和/或适当的协变量。在对超过 166,000 名 HMSA 会员的 4 年数据进行分析后，发现参与者的成本始终较低。对参与者和风险匹配的非参与者的实际医疗费用进行向上成本轨迹的预测建模表明，每位参与者每年可节省 350 美元。那些参加额外健康计划的人则节省了更多的成本。本研究说明了综合健康促进计划的经济价值。
