On the Ragged Edge of Medicine offers a unique and personal glimpse into a medical practice for the homeless and urban poor in Portland, Oregon. Told through fifteen patient vignettes and drawn from the author's decades of experience on the front lines, this revealing memoir illuminates the impact of poverty on the delivery of health services and the ways in which people adapt and survive (or don't survive) in conditions of abuse and deprivation. Kullberg's stories show the direct and sometimes devastating effects of poverty on personal health, poignantly demonstrating that medicine is as much a social enterprise as a scientific one.
