From lancets to laboratories: Medical schools, physicians, and healthcare in the United States from 1870 to 1940.

摘要

Healthcare in the United States experienced a remarkable transformation during the late 19th and early 20th centuries. While this transformation is well documented in descriptive historical accounts there are few empirical studies investigating the mechanisms through which reform was disseminated or the affects of the reform on healthcare. To this end, this dissertation examines four issues related to changes in the American healthcare industry during the early 1900's.; Chapter 2 examines changes in medical education. This chapter provides a qualitative analysis of motivations behind the medical education reforms in America and an empirical analysis of the shakeout of medical schools that occurred from 1905 to 1920. Licensing laws and medical school reviews were found to have influenced exiting decisions of many medical schools. Reform of medical education in America was followed by a disproportionate decline of physician supply in rural areas. Along these lines, Chapter 3 provides a case study of the geographic distribution of physicians during the early 20th Century. Data on individual physicians was compiled to analyze variation in physician counts across counties and to investigate out-migration of rural county physicians. This analysis indicates physicians were drawn more and more to areas offering better financial opportunities, greater access to medical facilities, and more opportunity for professional contact.; It is unclear to what extent patients initially benefited from the changes in medicine. Chapters 4 and 5 focus on one aspect of this issue by examining the impact of physicians on mortality rates. Chapter 4 utilizes the individual physician data from Chapter 3 to assess whether variation in physician counts explain variation in infant and non-infant mortality rates across counties. Estimates indicate that physicians were still unable to reduce mortality in the early 1920's. Chapter 5 focuses on the impact on maternal mortality resulting from the transition of childbirth during the first half of the 20th Century from the home to the hospital setting. Using hospital beds as a proxy for medical inputs, regression analysis revealed that the transition may have contributed to more maternal deaths until the introduction of sulfa drugs in the late 1930's.
