The Impact of Primary Care Dual-Management on Quality of Care

Abstract

Background: Discontinuity is common in US healthcare. Patients access multiple systems of care and in the nation's largest integrated healthcare system, Veteran's Administration (VA) patients frequently use non-VA primary care providers. The impact of this "dual-management" on quality is unknown. The authors' objective was to identify dual-management and associations with markers of care quality for hypertension and associated conditions. Methods: Data was collected via surveys and chart reviews of primary care patients with hypertension from six VA clinics in Iowa and Minnesota. Clinical measures abstracted included the following: goal blood pressure (BP) and use of guideline-concordant therapy, low-density lipoprotein (LDL) cholesterol, hemoglobin A1C, and body mass index (BMI). Dual-management data was obtained through self-report. Results: Of 189 subjects (mean age = 66), 36% were dual-managed by non-VA providers. There was no difference in hypertension quality of care measures by dual-management status. A total of 51% were at BP goal and 58% were on guideline-concordant therapy. Dual-managed patients were more likely to use thiazide diuretics (43% vs 29%; P = .03) and angiotensin receptor blockers (13% vs 3%; P
