Key result

Both the Omron HEM-722C and HEM-735C self-measurement devices satisfied the BHS and AAMI validation criteria for accuracy in elderly subjects and can be recommended for clinical use.

Why the study?

Do the Omron HEM-722C and HEM-735C automated devices provide accurate blood pressure measurements in elderly patients compared to a mercury sphygmomanometer?

Population

60 subjects aged more than 65 years, including individuals with extreme blood pressure values.

Implication

May support self-monitoring accuracy in elderly patients; leaves open prospective outcome validation before routine adoption.

Key Points

To clinically validate the Omron HEM-722C and HEM-735C blood pressure devices for elderly use according to BHS and AAMI criteria.
Conducted validation tests for two groups of 30 subjects over 65 years according to revised BHS protocol.
Graded measurement accuracy from A to D based on the BHS system.
Measured blood pressures using both devices and compared with mercury sphygmomanometer readings.
Omron HEM-722C achieved overall A/A grading and met AAMI accuracy criteria.
Omron HEM-735C achieved overall B/A grading and also met AAMI accuracy criteria.
Average readings were within 5 mmHg for 76% of HEM-722C systolic and 68% of HEM-735C systolic measurements.

Structured PICO

Do the Omron HEM-722C and HEM-735C automated devices provide accurate blood pressure measurements in elderly patients compared to a mercury sphygmomanometer?

Population

60 older adults aged >65 years, including those with extreme blood pressure values, evaluated to validate two automated blood pressure monitors.

Exposure

Blood pressure measurement using Omron HEM-722C and HEM-735C automated devices.

Comparator

Blood pressure measurement using a standard mercury sphygmomanometer.

Outcome

Device accuracy graded according to the British Hypertension Society (BHS) system (A to D) and the criteria of the Association for the Advancement of Medical Instrumentation (AAMI).surrogate

Both the Omron HEM-722C and HEM-735C devices meet BHS and AAMI validation criteria and can be recommended for clinical self-measurement of blood pressure in elderly patients.
