This sixth volume in the Collected Works of Florence Nightingale reports Nightingale’s considerable accomplishments in the development of a public health care system based on health promotion and disease prevention. It follows directly from her understanding of social science and broader social reform activities, which were related in Society and Politics (Volume 5). Public Health Care includes a critical edition of Notes on Nursing for the Labouring Classes, papers on mortality in aboriginal schools and hospitals, and on rural health. It reports much unknown material on Nightingale’s signal contribution of bringing professional nursing into the dreaded workhouse infirmaries. This collection presents letters and notes on a wide range of issues from specific diseases to germ theory, and relates some of her own extensive work as a nurse practitioner, which included organising referrals to doctors and providing related care.
