John Malcolm Hollingsworth, M.D.

Associate Professor, Urology


Dr. Hollingsworth is an Associate Professor of Urology. He received his medical degree from Georgetown University's School of Medicine in 2002, and earned a Master of Science degree in Health and Healthcare Research through the University of Michigan's Horace H. Rackham School of Graduate Studies in 2006. Following completion of his urology residency training at Michigan (2002-2008), he entered the prestigious Robert Wood Johnson Foundation Clinical Scholars Program (2008-2010). Since joining the faculty in 2010, Dr. Hollingsworth's clinical practice has focused squarely on the medical and surgical management of urinary stone disease. He co-directs the University’s multidisciplinary stone clinic. Using the shared medical appointment model, this clinic offers patients “one-stop shopping,” bringing together experts in Urology, Nephrology, and Nutrition.

In addition to delivering state-of-the-art clinical care, Dr. Hollingsworth maintains a robust research agenda that encompasses a broad range of health services disciplines. He has investigated the effect of financial incentives associated with physician ownership on procedure utilization. He has also examined the relationship between variation in provider practice and the quality and costs of urological care. His current line of inquiry explores the interface between primary and specialty care. With funding from the Agency for Healthcare Research and Quality, he is investigating how patterns of connection among surgeons, referring primary care physicians, and consultants impact the efficiency of care delivered around the surgical episode.
