OBJECTIVES: To determine blood pressure goal attainment levels and the factors influencing them for a low-income, uninsured population with hypertension.  METHODS: A retrospective, cohort study was carried out by reviewing patient charts at three different sites where patients from CareNet, a Toledo based safety-net organization, received primary care. Eligible subjects were at least 18 years old and were CareNet members for a minimum duration of one year between the study period of January 1, 2003 to December 31, 2008. Descriptive statistics were utilized to determine goal attainment. Chi-square analysis was used to determine variables that had significantly different goal attainment. A binomial logistic regression model was used to predict goal attainment. Goal attainment at the last recorded visit served as the dependent variable and was classified as 'Yes' and 'No' (determined based on JNC-VII guidelines). Age, gender, race/ethnicity, BMI, tobacco use, number of primary care visits, and pharmacotherapy treatment were used as predictor variables.  RESULTS: A total of 269 patients were included in the final analysis; 92 of these patients had diabetes while 177 didn't have diabetes as co-morbidity. The overall goal attainment was found to be 42.39% (n=39) in the patients with diabetes as co-morbidity and 60.45% (n=107) among the members without diabetes as co-morbidity. Chi-square analysis found patients the variables of co-morbidity (p=0.05) and number of visits (p<0.01) had significant differences in goal attainment. Patients who had primary care visits between 6-10 times were found to be significantly more likely (OR=3.705; CI: 1.670-8.218) to attain goal when compared to those who had just 1-5 visits. Notable trends were observed for other variables (co-morbidity,race/ethnicity,tobacco) but the effect was not significant. CONCLUSIONS: Goal attainment among CareNet members was found to be comparable to other studies and national statistics. Encouraging regular utilization of primary care services may further improve the clinical outcomes for a population utilizating a safety-net organization.
