Overview
Brief Summary
The purpose of this study is to test the effectiveness of physician profiling and care coordination by a diabetes resource nurse in improving the quality of diabetes care.
Detailed Description
HealthTexas Provider Network primary care practices with at least 10 Medicare diabetes patients over the age of 65 were randomized to one of 3 intervention arms: physician feedback of process measures using Medicare claims data ("Claims"); feedback of Medicare claims data plus clinical measures from medical record abstraction ("Claims+MR"); or both types of feedback plus a practice-based DRN ("DRN"). For the 12 months prior to the intervention and 12 months post-intervention, performance data on diabetes related processes of care (annual HbA1c testing, annual LDL cholesterol screening, annual hypertension screening, annual eye, foot, and renal assessment) and patient outcomes (HbA1c level, LDL cholesterol level, blood pressure) were collected from medical record abstraction and Medicare claims data. Pre-post change scores will be compared between intervention arms to examine effectiveness of physician profiling and care coordination by a diabetes resource nurse.

Arms & Interventions
Medicare Claims Feedback
Practices randomised to the Medicare Claims Feedback arm received period feedback on their performance on selected diabetes quality of care measures as reflected in the claims data for their diabetes patients.
Intervention: Medicare Claims Feedback
Medicare Claims+Medical Record Feedback
Practices randomised to the Medicare Claims + Medical Record Review Feedback arm received periodic feedback on their performance on selected diabetes quality of care measures as reflected in both the Medicare claims for the diabetes patients AND review/audit of their diabetes patients' medical records.
Intervention: Medicare Claims Feedback
Medicare Claims+Medical Record Feedback
Practices randomised to the Medicare Claims + Medical Record Review Feedback arm received periodic feedback on their performance on selected diabetes quality of care measures as reflected in both the Medicare claims for the diabetes patients AND review/audit of their diabetes patients' medical records.
Intervention: Medical Record Review
Medicare Claims+Medical Chart Review+DRN
In addition to the performance data from both Medicare Claims data and from review of patients' medical records, practices randomised to the Medicare Claims + Medical Record review + Diabetes Resource Nurse (DRN) had a diabetes resource nurse assigned to them, who was available to provide diabetes education and care-coordination type services for their diabetes patients.
Intervention: Medicare Claims Feedback
Medicare Claims+Medical Chart Review+DRN
In addition to the performance data from both Medicare Claims data and from review of patients' medical records, practices randomised to the Medicare Claims + Medical Record review + Diabetes Resource Nurse (DRN) had a diabetes resource nurse assigned to them, who was available to provide diabetes education and care-coordination type services for their diabetes patients.
Intervention: Medical Record Review
Medicare Claims+Medical Chart Review+DRN
In addition to the performance data from both Medicare Claims data and from review of patients' medical records, practices randomised to the Medicare Claims + Medical Record review + Diabetes Resource Nurse (DRN) had a diabetes resource nurse assigned to them, who was available to provide diabetes education and care-coordination type services for their diabetes patients.
Intervention: Diabetes Resource Nurse
Outcomes
Primary Outcomes
Change Score for "HbA1c <9 Percent"
Time Frame: This measure compared baseline values (01/01/2000-12/31/2000) to follow-up values (01/01/2001-12/31/2001)
Each patient was assigned a "change score" of -1, 0, or 1. A positive value indicated a patient non-adherent to the guideline recommendation for HbA1c \<9 percent at baseline had achieved such a level at follow up. Patient-level change scores were then summed and averaged over each study arm.
Change Score for "Blood Pressure (b.p.) <130/80 mmHg"
Time Frame: change from baseline (01/01/2000-12/31/2000) to follow-up (01/01/200112/31/2001)
Each patient was assigned a change score of -1, 0, or 1. A positive value indicated that a patient non-adherent to the guideline recommendation of blood pressure \<130/80 mmHg at baseline had achieved adherence at follow-up. Patient-level change scores were then summed and averaged over each study arm.
Change Score for "LDL <100 mg/dL"
Time Frame: change from baseline (01/01/2000-12/31/2000) to follow-up (01/01/2001-12/31/2001)
Each patient was assigned a "change score" of -1, 0, or 1. A positive value indicated that a patient non-adherent to the guideline recommendation of LDL \<100 mg/dL at baseline had achieved adherence at follow-up. Patient-level change scores were then summed and averaged over each study arm.
