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.

Read full description

This app is a collection of approximately 570 medical aphorisms, proverbs, historical quotations, and even a few light-hearted comments. I have put together this collection to remind physicians of the history of medicine and some of its earliest aspirations. In this cynical age, I hope it reminds the reader that medicine is more than just a business or scientific pursuit; it remains both a calling and an art. While some of the sayings are certainly dated, they should be read with a consideration for their historical context. A small number have been edited for length and readability. The app uses many of the Hippocratic aphorisms as a general backbone, which is then filled in with similar supporting quotations. The app is targeted mainly to physicians, but may be of interest to anyone interested in the history of medicine. The app now works on any device capable of running iOS 17.6 and higher. Navigation can be accomplished by swiping across the screen. Swiping towards the left advances to the next aphorism and swiping towards the right will take you back to the previous aphorism. Contact me on the webpage link if you have any favorite aphorisms to include in a future update.
