Article Abstract
Background: Blood pressure (BP) measurement being a part of clinical examination gives a fair idea about the hemodynamic status. The auscultatory method is considered as a gold standard, a simple, noninvasive way to measure BP in patients as well as in the healthy controls. The present study was designed to compare systolic BP (SBP) and diastolic BP (DBP) readings using a newer palpatory method with the standard auscultatory method and further assessing the reliability of the newer palpatory method.
Materials And Methods: A cross-sectional study comprising of a total of 400 (240 males and 160 females) individuals in the age range of 20-60 years were included in this study. BP measurement was done by the standard auscultatory method by one observer. Another observer blinded with BP records of the auscultatory method, measured BP using the newer palpatory method on the same individuals. The two methods were compared for the inter-rater reliability using intraclass correlation (ICC) statistics and agreement between two methods using Bland-Altman analysis.
Results: The present study observed excellent reliability of the newer palpatory method with the standard auscultatory method with an ICC value of 0.997 and 0.993 for SBP and DBP, respectively. Bland-Altman plot for both SBP and DBP using the auscultatory and newer palpatory method has shown minimum variability and good reliability when both methods are used by independent observers.
Conclusions: With practice and experience newer palpatory method can be used to assess BP with accuracy.

Article Synopsis
- Blood pressure (BP) measurement is a key part of clinical exams, and this study compares a newer palpatory method to the standard auscultatory method to evaluate its reliability for measuring systolic and diastolic BP.
- The study involved 400 participants aged 20-60, where one observer used the auscultatory method while a second, blinded observer used the palpatory technique to measure BP.
- Results showed that the palpatory method had excellent reliability, with very high ICC values (0.997 for SBP and 0.993 for DBP), indicating it can be accurately used for BP assessment with practice.
