Dr. James Fackler is an associate professor of anesthesiology and critical care medicine and pediatrics at the Johns Hopkins University School of Medicine. His areas of clinical expertise include acute respiratory distress syndrome, novel respiratory therapies, and signal fusion and monitoring.

Dr. Fackler received his undergraduate degree in biology from the University of Illinois and earned his M.D. from Rush Medical College in Chicago. He completed his residency in anesthesiology and performed a fellowship in pediatric intensive care and pediatric anesthesia at the Johns Hopkins University School of Medicine. Dr. Fackler joined the Johns Hopkins faculty in 2006.

He worked for the Cerner Corporation from 2002 to 2006 and left the position of vice president to return to academic medicine. He founded Oak Clinical Informatics Systems and consults for other device and information integration companies.

Dr. Fackler's research interests include optimizing patient surgical services by analyzing mathematical models of patient flow through hospitals, on either a scheduled or emergency basis.

He serves as the editor for Pediatric Critical Care Medicine and as an ad hoc journal reviewer for many notable publications including New England Journal of Medicine and Critical Care Medicine. He is a member of American Association of Artificial Intelligence, American Medical Informatics Association and the Society for Critical Care Medicine.

Dr. Fackler is a frequent lecturer and panelist on the subject of critical care informatics. He is an expert in data integration. more

Research & Publications

Research Summary

Dr. Fackler is working to build a mathematical model of how patients flow through a hospital. Approximately half of patients who undergo surgery have been previously scheduled. These are patients who are expected and for whom resources can be appropriately prepared in advance. The other half of patients enter as emergency cases and therefore are less predictable. By modeling the external variability of the latter group, hospitals might become better able to predict the influx of emergency cases. Improvements in predictability would enable hospitals to optimize resource preparation and scheduling of elective procedures, thereby enhancing patient service.

Dr. Fackler is also interested in data acquisition and data mining in the operating room and intensive care unit. In the ICU, each patient has 300–350 associated data elements. Blood pressure, heart rate, potassium concentration and hemoglobin level are just a few examples. Studies have shown that the human brain can comprehend seven individual parcels of data at once. If the data can be sorted into patterns, an individual may be able to manage seven individual patterns. Dr. Fackler hopes to identify patterns among the patient data and establish recognizable trends that occur over time. The understanding of such patterns and trends could help clinical professionals to make more educated, evidence-based decisions on patient care.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
