Preop Eval organizes and presents much of the guidance that one needs in order to evaluate and prepare adult patients for non-cardiac surgery. It is based upon the guidelines on this topic from the American College of Cardiology, the European Society of Anaesthesiology, the American Society of Anesthesiologists, the Institute for Clinical Systems Improvement, the American College of Chest Physicians, and more (full references in the app). The app contains 1 algorithm and 3 resources: the cardiac evaluation algorithm, guidance on starting and stopping key medications in the perioperative period, guidance on timing of surgery after cardiac events, and guidance on preoperative testing. It also contains a review of preoperative evaluation mainly for students and residents. The app addresses such common questions as: - who needs bloodwork before surgery? - who needs an EKG or a CXR? - how do I handle patients on warfarin, clopidogrel, and DOAC's? - which patients need adjustment of perioperative insulin and diabetic meds, and how? - which active cardiac conditions preclude surgery? - how long after MI or stent should a patient wait before surgery? - are there adjustments to make on psych meds, rheumatologic meds, ACE's and ARB's? This app is written and intended for practicing physicians like internists, family physicians, and hospitalists; for resident physician trainees; and for medical students. In addition to being a reference, the algorithm is written to be a teaching tool by not just delivering an answer, but instead walking a physician through the evaluation process so that one learns that process along the way. As an educator and clinician, I am interested in feedback and I would be grateful for guidance on improving the tool.

Welcome to Pedia BP. This application was designed and developed to more easily detect hypertension in children and adolescents. The blood pressure measurement calculator is developed from the National High Blood Pressure Education Program (NHBPEP,2005) Working Group on Children and Adolescents. The blood pressure measurement, SBP/DBP, are based on manual blood pressure measurements. In adolescents, BP equal to or exceeding 120/80 mmHg is prehypertension, even if this figure is less than the 90th percentile. It is critically important that hypertension and pre-hypertension are recognized and appropriately managed to decrease the risk of CAD, CVD, heart failure, CHD, and sleep apnea. Evidence shows that this problem is under-recognized due to a number of factors including lack of provider knowledge regarding the AHA blood pressure recommendations and the National High Blood Pressure Educational Program (NHBPEP) guidelines. Another issue is the complexity of factors involved in diagnosing HTN in this population delineated by the (NHBPEP) guidelines. The blood pressure tables include 1,904 variables based on gender, age, and height percentile delineated from the CDC development charts. The existing tables from The Fourth Report on the Diagnosis, Evaluation and Treatment of High Blood Pressure in Children and Adolescents, which contain hundreds of normal and abnormal blood pressure values based on gender, age, and height percentile, were analyzed and streamlined into a much simplified single user interface. The application makes it easy to identify abnormal blood pressure values in almost any potential care or screening setting. This approach is ideal when blood pressure is measured in any setting. The application screening tool can aid providers in accurate and timely evaluation of pediatric blood pressure readings, as well as aid in decision making regarding best practice with regard to management of issues identified.
