At least 3 BP measurements gives accurate data of patient's condition: Study

Press Trust of India  |  New Delhi 

At least three repeated measurement of during a clinic visit is required to reduce inaccurate classification of a patient's true condition and prevent misdiagnosis, a recent study has stated.

The study recently published in the Journal of was conducted by researchers at Public Foundation of (PHFI), AIIMS, New Delhi, and the Economics and Planning unit of the

Either due to patient load or lack of awareness among physicians, often single measurement is used to diagnose and manage This results in many people being diagnosed as having high and often receive treatment they may not need.

The study found 63 per cent higher prevalence of when estimated through a single blood pressure measurement, compared to an average of multiple measurements.

It has implications for India's newly launched National Mission in under which the and wellness centres (HWC) play a pivotal role in detection and management of non-communicable diseases, especially hypertension.

During the study, the authors observed that the median difference in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) increased as measurements moved to higher blood pressure categories.

This indicated the importance of repeating measurements especially in individuals with a high first blood pressure reading.

Dr Dorairaj Prabhakaran, Vice President, Research and Policy, at PHFI and one of the main authors of the study said, "There is a need to ensure accuracy in diagnosis and management of hypertension. It is vital that clinical guidelines recommend uniform evidence-based methods of arriving at final "

"Given that community health workers, workers or NCD care coordinators are likely to measure blood pressure initially, protocol guidelines should emphasize the importance of measuring thrice to prevent misdiagnosis and unnecessary commencement of hypertensive treatment in patients who only need to be encouraged to adopt a healthy lifestyle," Prabhakaran said.

Dr Ambuj Roy, a in the Department of Cardiology, AIIMS, and another of the study said, "In India, most physicians rely on a single measurement due to time constraints and in view of high clinical load in most health facilities. It is well known that BP varies from moment to moment with respiration, emotion, exercise, meals, tobacco, alcohol, ambient temperature, bladder distension, and "

"Medical practitioners must be encouraged to adopt the practice of repeated measurements in the same visit with the mean of the second and third measurements being the clinic BP, especially in patients with This will prevent mismanagement and misdiagnosis of patients," Dr Roy said.
