3 readings must for correct BP diagnosis


MUMBAI: Chances of a patient’s blood force readings not being correct are top if not taken thrice all over a seek advice from, unearths a brand new Indian find out about.


The find out about through the Public Health Foundation of India and AIIMS has calculated that there is a 63% higher prevalence of high blood pressure if handiest the primary blood force reading is regarded as for diagnosis compared to the imply of the second and third readings.

“Improper dimension may end up in misguided classification, overestimation of true BP, pointless treatment, and misinterpretation of the true prevalence of high blood pressure,” stated the authors of the find out about revealed in the Journal of Human Hypertension.

The standard blood force for a young person in the thirties is beneath 120/80 mmHg. However, it is known that blood force readings range with moods, foods, fever, among different factors. There also is a well-chronicled phenomenon called the white coat syndrome wherein an individual’s blood force rises merely through being around doctors. It is, hence, frequently beneficial that an individual’s BP readings must be repeated if the primary one is odd.

In current medical follow (either because of huge patient load or lack of information among physicians), regularly a unmarried BP dimension is used to diagnose and arrange high blood pressure in busy clinics, stated the authors. This leads to numerous patients being labelled as having top BP and receiving treatment that will not be wanted.

Dr Hemant Thacker from Jaslok Hospital on Pedder Road stated, “An astute physician understands a patient coming to him for the primary time might be crushed through the surroundings, the white coat, and history taking. This may just result in a improper reading.” He, alternatively, stated readings must be repeated provided that the primary one seems odd.

Although there are American and European guidelines on dimension of blood force, there is not any consensus at the number of beneficial measurements at a unmarried seek advice from or the method of arriving at final hospital BP reading.

Hence the PHFI-AIIMS find out about analysed the data of the National Family Health Survey (NFHS-Four) conducted in India from 2015 to 2016. Using statistical analysis, they discovered a 63% higher prevalence of high blood pressure when handiest the primary reading was once regarded as as an alternative of a median reading. “In the younger inhabitants, based on a unmarried BP dimension, the superiority of high blood pressure was once 16.5% and when the typical of second and third readings was once taken, the superiority reduced to 10.1%,” stated the find out about.


PHFI’s Dr Dorairaj Prabhakaran, one of the most authors, stated, “This huge relief in the number of folks needing treatment has massive implications for the individual (relating to warding off pointless remedies) as well as the health gadget (through reducing footfalls to hospitals as well as reducing healthcare costs).”


As the Centre is planning to arrange wellness clinics around the country, Dr Prabhakaran stated clearcut guidelines are wanted about repeat BP readings for community health staff and Accredited Social Health Activists (ASHAs) to follow.


Dr Thacker stated the dictum is if a physician will get an odd reading, then he must check the patient’s reading again whilst sitting and once whilst lying down. He added that the prohibit at which patients must be started on antihypertensive drugs depends upon their age, psychological standing and health. “If a 30-year-old patient has a reading of 140/90, I might put him on drugs, however would handiest recommend way of life modifications if the reading is for a middle-aged patient. A senior citizen with that reading wishes no drugs,” added Dr Thacker.
