RESUMO
BACKGROUND: Pre-hypertension (pHT) is frequently diagnosed in the primary care setting, but its management by primary care physicians (PCPs) is not well characterized. METHODS: All individuals aged 30-45 years who were insured by Clalit Health services in the Tel Aviv district and had their blood pressure (BP) measured from January 2006 to December 2010 were evaluated. Individuals were divided into three groups based on their initial BP value: optimal (< 120/80 mmHg), normal (systolic BP 120-129 or diastolic 80-84 mmHg) and borderline (130-139/85-89 mmHg). Groups were compared regarding clinical and laboratory follow-up performed by their PCP. RESULTS: Of the 20,214 individuals included in the study, 6576 (32.5%) had values in the pHT range. Of these, 2126 (32.3% of those with pHT) had BP values defined as "borderline" and 4450 (67.6% of those with pHT) had BP values defined as "normal". The number of follow-up visits by the PCP and repeat BP measurement were similar in those with "optimal" BP and pHT. A third and fourth BP measurement were recorded more frequently in those with pHT. In those with pHT, there were more recorded BP measurements than in those with borderline BP (3.35 ± 3 vs. 3.23 ± 2.6), but the time from the initial to the second measurement and a record of a third and fourth measurement were the same in the two groups. CONCLUSION: Identification of pHT does not lead to a significant change in follow-up by PCPs, irrespective of BP values in the pHT range.
