Primary Outcome Measures:
  • Means difference and risk ratio between and within groups of adherence to treatment [ Time Frame: at basal and 3, 6, 9 and 12 months ]
    It will be evaluated by two methods: pill count (proportion of pill taken as prescribed) and self-report using a structured validated questionnaire (proportion adherents in each group).

Secondary Outcome Measures:
  • Means difference and/or risk ratio between and within groups of clinical outcomes [ Time Frame: at basal and 3, 6, 9 and 12 months ]
    It will be evaluated mean blood pressure, proportion of complications, hospitalization and death in each group.

Detailed Description:
We will study two groups of 198 people with hypertension treated in ten health care units. One group will receive usual care dispensed in units (control). The other group (intervention) will be offered six individual assistance with health care worker physician or nurse) during the period of 9 months with a minimum interval of 30 days, plus 9 monthly visits structured by community health agents. Adherence will be measured in both groups at baseline and months 3, 6, 9 and 12, through validated questionnaire and pill count. Also evaluated clinical outcome measures (blood pressure, hospitalizations and deaths). The analysis will be done by intention to treat comparing adherence measures and clinical outcome between groups (Student t test and chi-square test) and within groups over time (paired t test and McNemar). It will be accepted p value <0.05.
