This is the third book in a series on the history of medicine and medical education by Kenneth M. Ludmerer, a practicing physician and historian of medicine at Washington University of St. Louis. The first, Learning to Heal: The Development of American Medical Education, published in 1985, dealt with the history of medical schools and medical education in the US from their origins in the 19th century to the late 20th century. In 1999 he published Time to Heal: Medical Education from 1900 to the Era of Managed Care. This book, Let Me Heal: The Opportunity to Preserve Excellence in American Medicine, published in 2015, is a sweeping history of graduate medical education in the United States from its inception to the current day.

In 13 chapters and 431 pages (334 pages of text, 97 of reference and index), Ludmerer traces the residency from early apprenticeship days to its metamorphosis (at Johns Hopkins, of which he is a justly proud medical school alumnus) into the embryonic form of what we now call an internship and residency. Giants like “The Four Doctors” (to use the title of John Singer Sargent’s famous portrait of William S. Halsted, William Osler, Howard A. Kelly and William H. Welch - but known simply as “The Big Four” at Hopkins) were the godfathers of the American postgraduate medical model which emphasized clinical science, teaching, patient care and research. The rise of acute care teaching hospitals as the venue of postgraduate medical education, and not the medical school or university, is an interesting story and one which Ludmerer tells in great detail over a number of chapters. It is one replete with predictable turf wars, professional turmoil and politics, and societal change in all aspects of the 20th century. This last phenomenon receives its due attention in every chapter but is dissected in meticulous detail in the final chapters dealing with the Libby Zion case, duty hours and the increasing role of the Accreditation Council for Graduate Medical Education (ACGME) in postgraduate medical education.

Beginning in the 1930’s, American medicine grew increasingly specialized and, in the ensuing decades, subspecialized, much to the consternation of pre-WW II general practitioners who, suddenly and for the first time, found themselves in the minority, in numbers and in influence, of their own profession. Concomitant with the phenomenon of specialization was the imprimatur by academic medicine of the structured, sanctioned residency as the sole route to specialty practice with, of course, the birth of associated accrediting agencies. Along with the move, physically, academically and politically, of postgraduate medical education to acute care teaching hospitals, the control of this education moved from medical schools to the profession at large.

Ludmerer deftly describes the “era of abundance”, the salad days of postgraduate medical education in the 1950’s and 1960’s when giants still made rounds on the floors of postgraduate medical venues; funds were plentiful; outside criticism was an as yet unborn bête noir; and social, economic and governmental curbs were only a tiny distant cloud in an otherwise blue sky. Ludmerer is correct in attributing much of medicine’s professional and social hegemony as well as its transient immunity to criticism in this era to the following evident successes of medicine: antibiotics; initial inroads into antineoplastic therapies; startling technological innovations in imaging; a burgeoning spate of life-saving vaccines; and spectacular advances in surgery, especially pediatric, cardiothoracic and transplant. Fatal diseases of the 1930’s and 1940’s were now often cured in days and of historical interest only.

Like all salad days, those of medicine eventually succumbed to new historical forces: foreign medical graduates in the workplace; the ever-growing financial burden of the residency; and economic pressures like Medicare and its associated regulation. There were other factors, too: professional and societal expectations of standardization and quality care; the explosion in subspecialties; the horrid wastefulness of unnecessary diagnostic tests and therapies borne of an earlier undisciplined abundance; the supercession of the intimate primary physician-patient relationship by the fragmented care of specialists and the rising supremacy of technology over personalized histories and careful physical examinations (why percuss the abdomen when you can get a CAT scan?). Dissatisfaction amongst residents is a dominant theme Ludmerer rightly raises early and often: the conflict and tension between education and service, between reasonable work and “scut”, between being a student and a worker (at times, quite a lowly one).

”High throughput” - the much more rapid turnaround time between admission to an hospital and discharge - has radically changed forever the entire nature of postgraduate medical education, and not for the better in the eyes of the author and of this reviewer, who were fellow residents a lifetime ago at Washington University in St. Louis. This decreased length of stay, a result of the remarkable improvements in diagnosis and therapy mentioned above, meant that the working life of providers (attending physicians, residents, physician assistants and nurses) was in high gear from admission to discharge, thereby increasing tension, likelihood for error and, exponentially, the workload for the resident while simultaneously and irrevocably damaging the possibility of a meaningful, careful provider-patient relationship (like a friendship, of which it is a subspecies, such relationships can not be rushed) and decreasing opportunities for learning. Medicare; changing patient populations; societal and professional disgruntlement; the Libby Zion mess and the ensuing cascade of regulations from all sides, but most especially the ACGME - all receive careful and systematic treatment in the final chapters of this monograph.

Ludmerer ends with a chapter listing what he sees as opportunities for achieving (or re-achieving) excellence. Indeed, he has made it the book’s subtitle. They are the following: a plea for the ACGME to revise its 2011 duty-hour regulations; an equally earnest hope that interns and residents will soon realize a more manageable patient load; a related wish for academic medicine to decrease the unfortunate occurrence of economic exploitation of house officers; a suggestion that this annotator shares, i.e., that the process of supervision, improved (but inadequately) with recent ACGME requirements, be further strengthened; and a hope that medical schools will restore teaching to the central place in the institutional value system it used to enjoy. Ludmerer issues a call for the more vigorous promotion of “an agenda of safety and quality in patient care” (page 312) and suggests that the education of residents be expanded to include venues outside in-patient sites. Elsewhere in the book, he also expresses the expectation that the inclusion into clinical teaching of private patients alongside “ward” patients, more feasible with recent improvements in the re-imbursement of medical care, be routine and maximized to the enjoyment and benefit of all concerned.
