The two interventions to be tested include the following: 1) a "basic" intervention delivering key evidence-based information to nurses, physicians, and patients while the patient is receiving traditional post-acute home health care; and 2) an "augmented" intervention transitioning patients to a Home-Based HTN Support Program that extends the information, monitoring, and feedback available to patients and primary care physicians for a 12-month period beyond an index home care admission. The interventions will be assessed relative to usual care and to each other. The analysis will estimate the impact of the basic and augmented interventions on nursing practices and processes of care, patient hypertension management (e.g., medication adherence), BP outcomes, and overall costs. Behaviors and outcomes will be measured at fixed points in time. Measures will be derived from a combination of primary and secondary data, including patient records, patient assessment instruments, patient interviews, home BP monitors, urine tests, and administrative files. Multivariate regression analyses will be conducted to determine intervention effects on study outcomes, adjusting for selected nurse and patient characteristics. Nurse level risk-adjustment will include demographics and other measures that might influence practice or processes of care, such as experience and education. Patient-level risk adjustment will include demographics, social support, and other characteristics that might influence behavior, service use, BP, or other health outcomes. Estimates of treatment-control group differences (for both treatments) generated by these models will be tested to determine the extent to which observed differences at the nurse and patient levels are attributable to the alternative intervention strategies.
