I just read "A Woman in Residence" by Dr. Michelle Harrison, who described her experiences as a single mother going through an OB-GYN residency later in life. She mentioned that there were such things as part-time residencies. When she wrote the book, apparently these residencies were rare and not really accepted by the medical community. Is this still the case now? Are there actually part-time residencies in all fields, or are these residencies still very uncommon and limited to primary care? I am also curious about research during residency. I know that some residency programs encourage and even allow time for research, but are there combined-research programs that have, say 3 years of clinical practice but a whole year of a post-doc type of research?
