随机治疗费用约束下的个体化治疗规则

Individualized treatment rules under stochastic treatment cost constraints

Hongxiang Qiu, Marco Carone, Alex Luedtke

摘要:

个体化治疗规则的估计和评价已被广泛研究,但在现有方法中,现实世界的治疗资源约束受到的关注有限。我们研究了一种设置,其中治疗是干预的基础上,协变量,以优化平均反事实的结果下,治疗成本的限制时,治疗成本是随机的。在一个特别有趣的特殊情况下,一个对应于鼓励治疗的工具变量被干预,对接受治疗的比例进行限制。对于这样的设置,我们首先开发了一种方法来估计最佳的个性化治疗规则。我们进一步构建了一个渐进有效的插件估计相应的平均处理效应相对于一个给定的参考规则。

英文摘要:

Estimation and evaluation of individualized treatment rules have been studied extensively, but real-world treatment resource constraints have received limited attention in existing methods. We investigate a setting in which treatment is intervened upon based on covariates to optimize the mean counterfactual outcome under treatment cost constraints when the treatment cost is random. In a particularly interesting special case, an instrumental variable corresponding to encouragement to treatment is intervened upon with constraints on the proportion receiving treatment. For such settings, we first develop a method to estimate optimal individualized treatment rules. We further construct an asymptotically efficient plug-in estimator of the corresponding average treatment effect relative to a given reference rule.
