 Care coordination, as defined by the VHA Office of Care Coordination, is a process of assessment and ongoing monitoring of patients using home telehealth to proactively enable prevention, investigation, and treatment that enhances the health of patients and prevents unnecessary and inappropriate use of resources. Care coordination embeds technology into a care management process. This results in the right care, at the right time, in the right place.The primary objective of the proposed study is to evaluate the efficacy of care coordination in improving outcomes in veterans with co-morbid DM and HTN, the two most common chronic conditions seen in VA Primary Care clinics. The specific aim is to compare outcomes of patients who receive the care coordination intervention to outcomes of patients who receive usual care. Three hypotheses will be tested: Compared to subjects who receive usual care, subjects who receive the care coordination intervention will have: 1 improved clinical measures hemoglobin A1c HbA1c and systolic blood pressure SBP at 6 and 12 months after study enrollment; 2 improved disease self-management knowledge, self-efficacy, and adherence at 6 and 12 months after study enrollment; and 3 improved quality of life and satisfaction with care at 6 and 12 months after study enrollment.Subjects wererecruited from VA Primary Care clinic rolls. 302 subjects were randomized to three groups: low-intensity monitoring plus nurse care management intervention n102; high-intensity monitoring plus nurse care management intervention n93; and usual care n107. In both intervention groups patients transmitted vital signs daily. In addition, the low intensity group answered two general health questions; the high intensity group responded to a complete range of questions focused on diabetes and hypertension, and received educational tips. The intervention groups participated in the protocol for 6 months following enrollment. Data were collected at baseline and at 6 and 12 months, including measures of clinical outcomes, quality of life, knowledge, adherence, self-efficacy, and satisfaction with care. In addition to these measures, data were collected to estimate the cost of the home telehealth intervention. Most subjects were male 98 Caucasians 96 with a mean age of 68 years range 40-89 years.
