Assess the influence of participation in a population health management (PHM) program on health care costs.
A quasi-experimental study relied on logistic and ordinary least squares regression models to compare the costs of program participants with those of nonparticipants, while controlling for differences in health care costs and utilization, demographics, and health status. Propensity score models were developed and analyses were weighted by inverse propensity scores to control for selection bias.
Study models yielded an estimated savings of $60.65 per wellness participant per month and $214.66 per disease management participant per month. Program savings were combined to yield an integrated return-on-investment of $3 in savings for every dollar invested.
A PHM program yielded a positive return on investment after 2 years of wellness program and 1 year of integrated disease management program launch.
评估参与人口健康管理（PHM）计划对医疗保健成本的影响。
一项准实验研究依赖于逻辑回归和普通最小二乘法回归模型，以比较计划参与者和非参与者的成本，同时控制医疗成本和利用、人口统计学和健康状况的差异。采用倾向评分模型进行分析，并对逆倾向评分进行加权，以控制选择偏差。
研究模型估计每月每个健康参与者可节省 60.65 美元，每月每个疾病管理参与者可节省 214.66 美元。将计划节省的费用加总，得出每投资 1 美元可节省 3 美元的综合投资回报率。
经过 2 年的健康计划和 1 年的综合疾病管理计划启动，PHM 计划实现了正投资回报。
