Nishant Sahni, MD, MS

Board-Certified Internal Medicine · Folsom, California

Most of what keeps people well is ordinary and unglamorous — someone who knows your history, reads your records, follows up on the result that came back late, and is reachable when you need them. Two decades in hospital medicine taught me how much that attention is worth. So I keep my panel small enough to give it, and I intend to be your physician for a long time.

The research degree matters more than it looks. It is why I read the study rather than the headline, and why I can tell you when the evidence behind a recommendation is thin.

Full-spectrum internal medicine

Hospital practice covers a wide span of adult medicine: open ICU coverage at PeaceHealth, Allina, and Valley Medical Center — sepsis, respiratory failure, shock; immunosuppressed and post-transplant patients at the University of Minnesota, where the usual signs of infection are unreliable, a problem I also published on; a long-term acute care service for the most fragile patients in the system, on ventilators and tracheostomies; and throughout, older adults with many conditions, long medication lists, and uncoordinated specialists.

In the office this matters most for knowing when a problem needs a hospital tonight rather than an appointment next week.

Research

Eleven peer-reviewed papers, largely on a single question: can you tell from a patient’s record who is about to get worse? A related strand asked it for transplant and immunosuppressed patients, in whom the usual warning signs are silent.

Patent and licensed model — Two prediction models built at the University of Minnesota: six-month mortality estimation from medical record data (patented), and a one-year mortality model (licensed by the University).
