In his work, Fish has forged strong relationships aimed at meeting the needs of SWHR’s patients, including close ties to surrounding hospitals and associated facilities, and to community organizations. Noting the inefficiencies in transitioning patients out of hospital stays, he used a data-driven approach and leveraged his partnerships with hospitals and post-acute care facilities to improve these transitions in care. These efforts ensure patients needing additional care following hospitalization receive it from a high-quality network of post-acute facilities, such as skilled nursing facilities, home health agencies, and rehabilitation facilities.

With a background in health services and population health, Fish has exercised effective population health management through innovation and robust data analytics, Salovey wrote. Several of his care delivery improvements have been published in the medical literature, and he has spoken internationally on his deployed population health strategies. He currently uses artificial intelligence models to predict key health care events, such as acute, unplanned hospitalizations, recurrent emergency room utilization, and progression of diabetes or kidney disease. These models identify rising risks for patients early in the course of illnesses, enabling clinical teams to intervene before patients’ conditions worsen.

“As a practicing primary care physician in a team-based practice, Dr. Fish understands first-hand the importance of monitoring and improving, when indicated, workplace processes and culture,” Salovey wrote. “It is with this careful attention to the needs of clinicians and staff that he helped to build the flexible and effective systems that enabled SWHR to respond rapidly to changes throughout the pandemic and maintain continuity of high-quality care for patients.”

Fish earned his B.A. in English with a minor in mathematics at Whittier College and his M.D. at Weill-Cornell Medical College. He did a general internal medicine residency at the University of California-Los Angeles (UCLA), where he also completed the Robert Wood Johnson Clinical Scholars Program and earned a Master of Science in health services research from UCLA’s School of Public Health. While at University of Texas Southwestern, Fish earned a Master of Science in healthcare management and administrative sciences and was appointed to the rank of professor of medicine, recognizing his publications and teaching activities.
