Evaluation of screening for hypertension in general practice with an automatic machine
Insights
Automatic blood pressure screening identified hypertension but faced low attendance and patient follow-up issues. Routine blood pressure checks during regular visits are more effective for case finding.
Area of Science:
- Cardiology
- Public Health
- Preventive Medicine
Background:
- Hypertension is a significant public health concern.
- Early detection and management of hypertension are crucial for preventing cardiovascular diseases.
- Current screening methods face challenges in patient engagement and follow-up.
Purpose of the Study:
- To evaluate the effectiveness of automatic blood pressure devices for screening hypertension in a primary care setting.
- To assess patient attendance rates and follow-up adherence after screening.
- To compare automatic screening with routine blood pressure measurement during general practitioner visits.
Main Methods:
- An automatic blood pressure device was used to screen patients aged 30-65 years registered at a health center.
- Patient attendance, initial high readings, and follow-up adherence were recorded.
- Retrospective analysis of medical records was conducted for newly diagnosed hypertensive patients.
Main Results:
- Only 55% of eligible patients attended the screening.
- Previously recognized hypertension was more common in attenders.
- Two-fifths of newly diagnosed hypertensive patients defaulted from follow-up within one year.
- A significant proportion of patients had prior abnormal readings or unrecorded measurements.
Conclusions:
- Automatic blood pressure screening devices are not a substitute for systematic case finding.
- Routine blood pressure measurement during routine consultations is a more efficient method for detecting hypertension.
- Addressing patient engagement and follow-up is essential for effective hypertension management.
Abstract:
An automatic device for measuring blood pressure was used to screen all patients aged 30 to 65 years registered at a health centre. Of those who were eligible, 55% attended. Patients with previously recognised hypertension were more common among the attenders than among the non-attenders. High readings obtained on the automatic device possibly deterred some patients from reattending for follow up measurements of blood pressure. Although the device is quick and easy to use, the logistic challenge of formal blood pressure screening is considerable. Hypertension was discovered in 52 patients (mean diastolic pressure greater than 100 mm Hg). Retrospective analysis of their medical records showed that a third had had an abnormal blood pressure reading noted during the past 10 years and no further action had been taken, and almost three quarters had attended their practitioner during the previous year without having a blood pressure measurement recorded. One year after the screening procedure two fifths of the newly discovered hypertensive patients had defaulted from follow up and treatment. Automatic devices are not a short cut to the discovery of occult hypertension. Case finding by routine measurement of blood pressure at surgery visits is more efficient.
