简要总结
The purpose of this study is to evaluate if the use of a phone based motivational interviewing among minority populations who received a coronary stent can improve adherence to antiplatelet agents from approximately 51% to 66% (15 percentage point increase) at 12 months post stent placement when compared to a mailed educational DVD.
详细描述
Other aims are: 1) Improve the self reported adherence of antiplatelet medications 2) Identify specific barriers for the use of post PCI anti-platelet therapy among minority populations enrolled in Humana by administering a short survey at the baseline recruitment call and at the 12 month follow up call, 3) identify predictors of never filling an anti-platelet therapy prescription post PCIS.
Inclusion criteria:
We will include black or Hispanic patients having coronary stenting using the following codes for bare metal or drug eluting stents: ICD-9 procedure codes (36.06) or (36.07), MS-DRG codes 247-249 or CPT codes 92980, 92981, C1984 G0290, G0291. The identification period will last approximately 10 months.
Primary Outcome: Medication Possession ratio as a dichotomous variable (appropriate/not appropriate adherence) and as a continuous variable
Secondary outcomes:

结局指标
主要结局
Number of Participants With Appropriate Adherence/ Medication Possession Ratio (MPR)
时间窗: 12 months after receiving coronary stent
Medication Possession ratio (MPR) is a continuous multiple interval measure of medication availability. This is a validated method of estimating medication adherence . The medication possession ratio is defined as the sum of the days' supply of medication divided by the number of days between the first fill and the last refill plus the days' supply of the last refill.We will use the previously validated cutpoint of MPR\>=.80 to define the binary outcome of Appropriate Adherence
次要结局
- 4-Item Morisky Medication Adherence Scale (MMAS-4)(At 12 month post stent placement)
