A comparison of plans for hypertension screening

Area of Science:

• Biostatistics
• Medical Screening

Background:

• Hypertension screening is crucial for early detection and management.
• Previous research by Donner and Bull explored different screening plan efficacies.

Purpose of the Study:

• To compare the power of screening plans based on the mean versus the minimum for hypertension detection.
• To evaluate the performance of these plans across various false diagnosis probabilities.

Main Methods:

• Comparative analysis of two screening plan strategies: mean-based and minimum-based.
• Statistical power and size calculations were employed.

Main Results:

• Mean-based screening plans demonstrated higher statistical power in identifying true hypertension cases.
• The difference in power between mean-based and minimum-based plans diminished at acceptable false diagnosis rates (sizes).

Conclusions:

• While mean-based plans show a theoretical advantage in power, minimum-based plans remain competitive for practical hypertension screening.
• The choice of screening plan may depend on the acceptable balance between sensitivity and specificity.
