Abstract
Physician group practices in the U.S. have grown and changed significantly in terms of health professional team composition, employment contract types, ownership type, size, and management in the last 20 years. In the past, physicians were largely selfemployed or part of small practices, however today's physicians are employed by large healthcare organizations, as well as integrated delivery systems.1 Between the years of 1996-1997 and 2004-2005, the proportion of physicians in solo and two-physician practices has decreased significantly from 40.7 percent to 32.5 percent.2 Today, most physicians work in the group practice setting in the United States. Moreover, physicians are increasingly practicing in mid-sized, single-specialty groups.

No study has yet to provide a comprehensive overview regarding group practice trends from the literature. In this comprehensive literature review, we assess the definitions of a medical group practice, describe recent group practice trends in the U.S, and offer a typology of group practice size
Data was collected on the title of the study, author(s), year of publication, journal, original versus review, the inclusion of a definition regarding group practice, whether the study addressed group practice trends or group practice size, the inclusion of a definition regarding a large group practice, whether the study was specific to anesthesiology or a different specialty in the hospital setting
Summary
Physician group practices in the U.S have grown and changed significantly in terms of health professional team composition, employment contract types, ownership type, size, and management in the last 20 years. Physicians are increasingly practicing in mid-sized, single-specialty groups [2]. It is important to understand the recent trends in medical group practice establishments and identify a typology for group practice size. No study has yet to provide a comprehensive overview regarding group practice trends from the literature. In this comprehensive literature review, we assess the definitions of a medical group practice, describe recent group practice trends in the U.S, and offer a typology of group practice size. We characterize market outlook and recommend steps for future research focused on understanding and predicting medical group consolidation and mergers
