Objectives:

To assess the association of HEDIS C&M phase follow-up measure with ADHD medication adherence.

Methods:

A retrospective study was conducted using Medicaid data (2014–2016) of children initiated with ADHD medication. Patients were categorized as meeting the C&M follow-up measure or not according to the HEDIS specifications. Medication adherence was measured using both Proportion of Days Covered (PDC) & Group-Based Trajectory Modeling (GBTM). The association of medication adherence with HEDIS measure was assessed using Chi-square test.

Results:

Nearly all (97%) children with PDC≥0.7 and 72% of patients following the late decliner adherence trajectory met the HEDIS C&M follow-up criteria. In contrast, none of the children with PDC<0.7 and only two following rapid and slow decliner trajectories met the criteria.

Conclusion:

ADHD medication adherence, regardless of how it was measured, clearly differentiated children with and without C&M phase follow-up, which essentially questions the implication of HEDIS C&M phase follow-up care measure.

医疗保健有效性数据和信息集 (HEDIS) 随访护理措施和医疗补助受保多动症儿童的药物依从性协会

目标：

评估 HEDIS C&M 阶段随访测量与 ADHD 药物依从性的关联。

方法：

使用 ADHD 药物开始的儿童的医疗补助数据（2014-2016）进行了一项回顾性研究。根据 HEDIS 规范，患者被归类为符合 C&M 随访措施或不符合标准。使用天数比例 (PDC) 和基于组的轨迹建模 (GBTM) 测量药物依从性。使用卡方检验评估药物依从性与 HEDIS 测量的关联。

结果：

几乎所有 (97%) PDC≥0.7 的儿童和 72% 遵循晚期下降者依从性轨迹的患者均符合 HEDIS C&M 随访标准。相比之下，PDC<0.7 的儿童中没有一个符合标准，只有两个以下快速和缓慢下降轨迹符合标准。

结论：

ADHD 药物依从性，无论是如何衡量的，都清楚地区分了有和没有 C&M 阶段随访的儿童，这从根本上质疑了 HEDIS C&M 阶段随访护理措施的含义。
