We evaluated and compared different methods for measuring adherence to Oral Antihyperglycemic Agents (OHA), based on the correlation between these measures and glycated hemoglobin A1C (HbA1c) levels in Medicaid patients with Type 2 diabetes. An observational sample of 831 Medicaid patients with Type 2 diabetes who had HbA1c test results recorded between January 1, 2001 and December 31, 2005 was identified in the Indiana Network of Patient Care (INPC). OHA adherence was measured by medication possession ratio (MPR), proportion of days covered (PDC), and the number of gaps (GAP) for 3, 6, and 12-month intervals prior to the HbA1c test date. All three OHA adherence measurements showed consistent and significant correlation with HbA1c level. The 6-month PDC showed the strongest association with HbA1c levels in both unadjusted (-1.07, P<0.0001) and adjusted (-1.12, P<0.0001) models.
我们基于这些测量方法与医疗补助计划中2型糖尿病患者糖化血红蛋白A1C(HbA1c)水平之间的相关性,评估并比较了测量口服降糖药(OHA)依从性的不同方法。在印第安纳州患者护理网络(INPC)中,确定了一个观察样本,其中包括831名在2001年1月1日至2005年12月31日期间有HbA1c检测结果记录的医疗补助计划2型糖尿病患者。通过药物持有率(MPR)、覆盖天数比例(PDC)以及在HbA1c检测日期前3个月、6个月和12个月间隔的用药间断次数(GAP)来衡量OHA依从性。所有这三种OHA依从性测量方法均与HbA1c水平显示出一致且显著的相关性。在未调整模型(-1.07,P<0.0001)和调整模型(-1.12,P<0.0001)中,6个月的PDC与HbA1c水平的关联最强。
