Blood Pressure Protocol: Processing Time of Standard Versus Automated

Area of Science:

• Clinical practice guidelines
• Cardiovascular medicine
• Health services research

Background:

• Accurate blood pressure (BP) measurement is critical for diagnosing and managing hypertension.
• Automated office blood pressure (AOBP) is increasingly adopted, but its implementation challenges in lower-resource settings require further investigation.
• This study addresses the feasibility of AOBP in urban community health centers.

Purpose of the Study:

• To compare patient processing times between standard blood pressure measurement and automated office blood pressure (AOBP) in an urban community health center.
• To evaluate the impact of AOBP on clinic workflow efficiency.

Main Methods:

• A comparative study was conducted over two months at an urban community health center.
• Patient processing times were recorded using standard care for one month and automated office blood pressure (AOBP) for the subsequent month.
• Data were analyzed to compare average patient processing times between the two protocols, particularly when initial BP readings exceeded 140/90 mmHg.

Main Results:

• A total of 157 adult BP measurements were analyzed, with 20% requiring a second reading or AOBP.
• Mean processing times were similar between standard care (8.25 minutes) and AOBP (8.38 minutes), with no statistically significant difference (P=.84).
• In the AOBP group, 60% of patients achieved a BP below 140/90 mmHg, and 80% of those with elevated AOBP had their treatment plan discussed.

Conclusions:

• Automated office blood pressure (AOBP) can be implemented in clinic workflows without significantly increasing overall patient processing times.
• AOBP may help reduce clinical inertia by enhancing confidence in BP measurement accuracy.
• The findings support the integration of AOBP protocols in primary care settings, even in lower-resource environments.
