The Mount Sinai Hospital admitted its first patient, a surgical case, on June 8, 1855; three days after opening its doors. Dr. Israel Moses operated on L.S., a 42-year old male with a fistula-in-ano, who went home five days later in good condition. 

While providing outstanding patient care has always been the mission of The Mount Sinai Hospital, providing exceptional physician education has been an equally important hallmark in the hospital’s decades-long history. With its chartering in 1963, the Mount Sinai School of Medicine, now called the Icahn School of Medicine at Mount Sinai, became the first medical school to grow out of a non-university in more than 50 years. The fact that the hospital was encouraged to found a school is a testament to its tradition of excellence in patient care as well as research and education.

In 1872, The Mount Sinai Hospital moved from its original 45-bed building to space on Lexington Avenue, which nearly tripled the hospital’s capacity. Coinciding with the relocation was the formation of the Medical Board, a group established to set rules and regulations for the growing medical staff. By their own definition, they were organized “for the consideration of all matters appertaining to the medical management of the Hospital.”

In 1877, the hospital formally divided the house staff into medical and surgical divisions, each with a senior and junior resident. Surgical volume grew and by 1899, the caseload exceeded 2,000 operations. By 1904, when the hospital moved to its current location at 100th Street and Fifth Avenue, approximately four house surgeons were completing their training at The Mount Sinai Hospital each year. Today, the General Surgery training program at The Mount Sinai Hospital employs about 85 house officers.


Research at Sinai

The Icahn School of Medicine at Mount Sinai has received international recognition for producing ground-breaking clinical and basic science research. The National Institute of Health has awarded Mount Sinai more than $311 million in grants, ranking the institution #18 among the nation’s accredited medical schools. Consistent with the institutional mission to advance medical science, The Mount Sinai Department of Surgery fosters academic excellence and advancement by continually pursuing a variety of research projects.

Our residency program is a 5-year program; as such, dedicated time-off for research is not required. Residents who choose to pursue additional research typically take up to a two-year hiatus between PGY3 and PGY4 years. All surgical residents have a research requirement during their clinical years. Residents are required to participate in a research project under the direction of an assigned faculty mentor. The goal of this initiative is to equip the resident with basic research and investigative skills to carry out a research project from inception to publication. This includes the selection of a topic, experimental design, statistical analysis of data, and eventual publication in a high-impact surgical journal. The requirement is a minimum of one retrospective or prospective study published in an appropriate peer-reviewed journal.

In addition, Mount Sinai currently offers one dual surgery/MPH position per year at the discretion of the Surgical Residency Director. Offered through The Icahn School of Medicine at Mount Sinai, courses are scheduled during autumn, winter, and spring terms. Participating physicians complete all MPH degree requirements during the last four years of residency training.
