HERRERA, Rodolfo; BADIEL, Marisol  and  ZAPATA, Helmer. Factors associated with lack of blood pressure control in patients enrolled in a hypertension control program of a private primary Health Care Organization in Cali, Colombia, in 2004. Rev. Colom.

Objectives: to determine the factors associated to the lack of control of arterial blood pressure in patients enrolled in a hypertension control program of a private primary health care organization in Cali, Colombia in 2004. Methods: descriptive cross-sectional study. 356 patients >18 years were randomly chosen from the hypertension control program. Those patients with systolic blood pressure >139 mm Hg or diastolic blood pressure >89 mm Hg were classified as patients with lack of blood pressure control. Risk factors that could not be modified, behavioral, biological and administrative factors, were considered independent variables. Through a bivariate and multivariate analysis, factors associated to lack of blood pressure control were identified. Results: the prevalence of lack of blood pressure control in this health care organization was 30,1% (95% CI, 25,3-34,8), being higher in males (c2= 9,368; p=0,002). Adherence to pharmacological treatment was 56,2% (95% CI: 51,0% - 61,3%). Odds ratio (OR) for lack of blood pressure control adjusted by gender and according to hypolipemic drugs combination was 1,71 (95% CI: 1,0-2,94); OR according to the contracted health care organization in comparison with the institutional health care was 2.13 (95% CI: 1.3 - 3.5). Conclusions: the prevalence of lack of blood pressure control in a hypertension control program of a private health care organization was 30,1%. Associated factors were: type of health care organization, male gender, use of inhibitors on angiotensing-converting enzyme and drug interaction with concomitant use of hypolipemis.

Keywords : arterial hypertension; lack of blood pressure control; prevalence of arterial hypertension; health care provider.
