Multifactor cardiovascular disease risk reduction in medically underserved, high-risk patients.

Few data exist on the effectiveness of cardiovascular disease (CVD) risk-reduction programs in patients with limited access to health care. The objective of this project was to evaluate a disease management approach to multifactor CVD risk reduction in patients with limited or no health insurance and low family income. Patients (n = 148) were recruited from not-for-profit or free clinics and hospitals and randomized to usual care or usual care plus team case management. Mean age was 59.3 years, 57% were women, 50% had less than a high school education, 57% were Hispanic, and 64% had no health insurance. All had > or =1 increased risk factor for CVD, and 24.5% had documented coronary artery disease. Follow-up measurements were obtained at 6 and 12 months. Primary outcomes were low-density lipoprotein cholesterol and systolic blood pressure. The disease management program was supervised by a physician, delivered by nurses and dietitians, and included comprehensive lifestyle changes and medications. Data were collected on 91% of patients at 12 months. Disease management produced clinically important decreases in selected risk factors compared with usual care, including systolic blood pressure (p <0.01) and low-density lipoprotein cholesterol (p <0.03). More patients with disease management than those with usual care moved from "high" and "very-high" risk to lower risk categories for selected risk factors. In conclusion, the disease management program had excellent retention and lower CVD risk factors and demonstrated the potential of such approaches for decreasing long-term disease burden in selected medically underserved populations.

Successful dietary changes in a cardiovascular risk reduction intervention are differentially predicted by biopsychosocial characteristics.

BACKGROUND: Psychosocial factors have demonstrated associations with both prognosis of patients with cardiovascular disease (CVD) as well as the development of CVD. Psychosocial distress may influence health behaviors (such as eating behavior) that increase cardiovascular risk. METHOD: The purpose of this research was to evaluate the role of psychosocial distress on intake of high-fat snacks and fruits and vegetables in 740 men and women, identified as high risk for cardiovascular disease, who took part in a 1-year cardiovascular risk factor reduction program. RESULTS: Participants who were more successful at decreasing or staying at an optimal level of high-fat food intake had lower levels of baseline total psychosocial distress and worry and decreases in total psychosocial distress. A greater success rate at increasing fruit and vegetable intake or staying at an optimal level of fruit and vegetable intake was associated with changes in Type A and competing behaviors. CONCLUSIONS: Results from these analyses suggest that baseline levels and changes in psychosocial variables, particularly decreased psychosocial distress, were associated with improvements in healthful eating behaviors. Further work may provide information that could be useful in tailoring health behavior interventions to specific subgroups based on psychosocial characteristics, initial health behaviors, and demographic characteristics.

Determinants of exercise encouragement practices in hemodialysis staff.

The objective of this study was to survey patient care staff to (a) determine their perceived skills for and attitudes toward assessing physical functioning and encouraging exercise, (b) assess practice related to assessment of physical functioning and exercise encouragement, and (c) identify factors that predict encouragement of exercise in patient care staff. This was a cross-sectional, descriptive study in which questionnaires were completed by 100 patient care staff (RN, LVN, RD, SW, and patient care technicians) in five freestanding hemodialysis clinics. Frequency responses were calculated for the items of interest, and multiple regression analysis was performed to identify predictor variables of exercise encouragement practice (i.e., frequency of encouragement of exercise to patients). Four variables significantly predicted exercise encouragement activity: job position requiring professional training, the perception that patients lacked motivation to exercise, the perception that the staff member did not have skills to motivate patients to exercise, and the perception that it was not a part of the job responsibility.
