Comparison of hypertension treatment on and off the worksite

A survey was carried out in two plants in Haifa, Israel on the prevalence of treated and controlled hypertension. In both plants hypertension treatment was being carried out by family physicians at regular family clinics. In factory A, after screening, a programme of follow-up and treatment by the plant doctor and nurse was introduced. In factory B all hypertensives continued to be referred to their family physician for treatment and follow-up. One year later all previously detected hypertensives were reassessed. The percentage of treated hypertensives had increased from 70.9% to 100% in factory A, and from 55.0% to 62.1% in factory B. The percentage of controlled hypertensives among those treated had increased from 52.7% to 83.7% in factory A, and from 28.0% to 38.9% in factory B. Thus, the percentage of all hypertensives who were controlled increased from 37.3% to 83.7% in Factory A and from 15.4% to 24.1% in Factory B. The introduction of on-site treatment and follow-up of hypertension by a doctor-nurse team was associated with marked improvement of all aspects of hypertensive care.
