Pediatricians now have a new and simple way to diagnose a serious problem facing our nation's children - thanks to David Kaelber, M.D., Ph.D., M.P.H., MetroHealth System pediatrician, internist, and chief medical informatics officer and Case Western Reserve University School of Medicine researcher and faculty member. Nearly 75% of cases of hypertension and 90% of cases of prehypertension in children and adolescents go undiagnosed.
These troubling statistics were documented in previously published research by Dr. Kaelber. From this research, Dr. Kaelber and fellow researchers felt that one of the main reasons for the under-diagnosis may be due to the complex chart currently used to help physicians and medical personnel identify high blood pressure in children. So Dr. Kaelber's team simplified the chart - focusing solely on a child's age and gender - eliminating the need for a height percentile and reducing the number of values in the blood pressure table from 476 to just 64. The revised chart and accompanying description are published in the June issue of the journal Pediatrics.
The American Academy of Pediatrics and the American Heart Association recommend that blood pressure checks be done at all pediatric visits for health care (including dental and optometric appointments) for children ages 3 to 18. The current standard chart used by healthcare providers to evaluate pediatric blood pressure is from the National Heart, Lung, and Blood Institute and includes hundreds of normal and abnormal blood pressure values. In order to differentiate between normal and abnormal readings, providers need to, not only remember the variety of blood pressure ranges, but also know the child's height percentile - which can be difficult to verify, especially in non-primary care settings.
