    Anish has had the opportunity to present his work at multiple national and
    international EM and Critical Care conferences. Anish will be beginning a
    fellowship with the National Clinician Scholars Program here at Penn and
    plans to continue to explore methods of improving the delivery of emergent
    and urgent care through innovation and health policy. He will be working in
    the PPMC ED on a per diem basis. Amongst all of this, Anish is most proud
    to have recently become a father; he and his wife welcomed a baby boy in

  • Dr. Baumlin

    Kevin M. Baumlin, MD, FACEP

    It is with great enthusiasm that we announce Kevin M. Baumlin, MD, FACEP, as Chair of Emergency Medicine at Pennsylvania Hospital, and Vice Chair of Emergency Medicine for the Perelman School of Medicine. Kevin joins Penn Medicine as a globally recognized physician leader, and an accomplished clinician with a unique combination of applied capabilities including informatics, operational innovation, and quality and performance improvement. With more than 25 years of professional experience in medicine, Kevin comes to Penn from his role as Chair of Emergency Medicine at Mount Sinai Beth Israel Hospital in New York, a position in which he had direct oversight

    of the facility’s 265 clinical care providers, 110,000 patients, and 45 residents. During his time in this role, Kevin oversaw the development and implementation of programs that resulted in significant operational improvements including a dramatically reduced wait time in the Emergency Room and improved Press Ganey scores. During that time, he was also an active member of several other committees including Quality and Performance, Patient Experience, and the hospital’s Medical Board.

    Kevin’s academic interests lie primarily in informatics and geriatric emergency medicine. He has published and lectured widely on both topics in leading academic journals.

    He was a key driver in the development of New York’s first Geriatric Emergency Department – a groundbreaking initiative in 2012 that was recognized by the New York Times. He was also instrumental in the creation of the widely recognized Care and Respect for Elder Emergencies (CARE) volunteer program for geriatric ED patients, as well as the Novel Interdisciplinary Care for Emergencies (NICE) program for frequent ED visitors. Both the CARE and NICE programs had a positive impact on patients, reducing both frequent visitor usage and the number of falls for geriatric patients.

    As the lead physician for Mount Sinai’s implementation of EPIC, Kevin was responsible for engineering an on-time, under-budget implementation that saw the whole enterprise transition from paper to electronic medical records. At the same time, he also supervised a smooth transition for the Emergency Department without a decrease in revenue.

    Kevin holds multiple professional certifications and memberships. In 2013 he received a LEAN Healthcare Certificate from the University of Michigan, and in the same year also earned an Accelerated Implementation Methodology (AIM) Certificate. Kevin also holds a 10x10 certification from the American Medical Informatics Association, and the American Board of Emergency Medicine. Recently he received board certification in Clinical Informatics from the American Board of Preventative Medicine. Kevin is a member of the Society for Academic Emergency Medicine and the American College of Emergency Physicians. Previously, he also served as Chair of the informatics committee for both groups.

    Over the course of his career, Kevin has also received several prominent honors and awards including multiple recognitions for excellence in teaching and patient care.

    To his peers, Kevin is known for his collaborative style of leadership, working with teams across disciplines to achieve his goals. At Pennsylvania Hospital, Kevin will work closely with members of the leadership team to improve ED patient throughput and, as a skilled and committed educator, he will work to develop professional development programs for attending physicians.

    As Vice Chair of the department of Emergency Medicine, Kevin will serve on the department’s Senior Leadership Council to provide guidance on the strategic direction of clinical, education and research missions. Specifically, he will provide guidance on the development of potential new business lines for the department regarding specialty populations. Furthermore, he will work towards a closer clinical integration of all UPHS Emergency Departments to help ensure that the branding of Penn Emergency Medicine is seamless across all our entities.

    With a proven track record of improved quality of patient care and Emergency Department operations, we look forward to having Kevin on our team.
