Dr. Louis Leff is a physician specializing in Internal Medicine by trade and a computer programmer by nature. Read about his journey to create EBMcalc.
It was the mid-1990s and the World Wide Web was beginning its exponential expansion. I had been writing computer programs since the 1970s but had always been frustrated by the difficulty of making programs work on different platforms. Like so many wonderful breakthroughs, this frustration fueled my tenacious desire to create a program to aid evidence-based medicine that can run everywhere, on every platform so that all healthcare professionals can benefit from it.
EBMcalc has been fully integrated in many partner sites, including DynaMed®, STAT!Ref, Epocrates, WebMD, ClinicalKey, OvidMD, and many more sites. Translated into 11 languages, EBMcalc is also a prominent component of Merck Manuals. EBMcalc is the industry standard of evidence-base medicine calculation and decision support.
The full utility of EBMcalc would not be realized until it could be fully integrated into electronic health records (EHR) so that patient data would be automatically transferred into individual calculators and made available world-wide. This dream became a reality with the help of FHIR (Fast Healthcare Interoperability Resources), a new standard that has paved the way for true interoperability between EHRs.
EBMcalc was reimagined and rebuilt to use the FHIR standard. This year, Cerner fully vetted and validated the new EBMcalc FHIR app, and it is readied for licensing to Cerner clients. Hundreds of EBMcalc calculators can now pull data directly from the EHR.
During a public health crisis, the need for interoperable clinical decision tools could not be more evident, and two COVID-19 calculators are already available. Combining fast-paced research, EBMcalc’s programming capabilities, and the interoperability of FHIR, evidence-based medicine can be applied faster and to more patients than ever before.
Louis Leff MD, FACP, a Pittsburgh internist, earned his bachelor's degree at the University of Pittsburgh and his medical degree at the University of Pennsylvania School of Medicine. He completed Internal Medicine Residency at the University of Pittsburgh Medical Center, later receiving certification in Internal Medicine, Geriatric Medicine and ACP Fellowship, and Clinical Informatics. He currently holds the position of Clinical Professor of Medicine at the University of Pittsburgh and serves as the Medical Director of eRecord at UPMC Shadyside Hospital.
Dr. Leff has great interest in medical computing, and is the author of EBMcalc, an evidence-based medicine computing tool. He also serves as Editor for Calculators at DynaMed.
In 2003 Dr. Leff was presented the Laureate Award by the American College of Physicians (ACP). The Laureate Award honors Fellows and Masters of ACP who have demonstrated a long-term commitment to excellence in medical care, education or research, and to service to their community. In 2012 Dr. Leff was named Top 25 Clinical Informaticists by Modern Healthcare magazine.
