Effects of a screening program for hypertension in a community.

The effect of a population screening for hypertension was assessed through a subsequent survey performed 1 year later. All the hypertensives identified at the first visit (239 subjects, 15.6% of the whole screened population) were invited for a re-examination: the adhesion rate was 84.5%. After the screening, a high proportion of subjects (74.7%) had contacted their physicians because of their blood pressure. The most common advice physicians gave was to have further measurements of blood pressure (72.8%). Laboratory tests were prescribed in 62 patients (41.1%), but a complete assessment of a target organ damage was carried out in few cases (1.9%). Only 19.5% of patients started a course of treatment during the year following the screening and no more than one-third of those with moderate to severe hypertension. Out of the 176 subjects showing other cardiovascular risk factors at the screening, only 12 reported they had modified their habits 1 year later. Our results suggest that a screening for hypertension, when performed without any liaison with other medical facilities, seems to have a poor impact on physicians' and patients' attitudes towards hypertension.
