The British Medical Journal archive http://www.bmj.com/archive is a great resource for finding out more about historical health aspects, as the letters and case reports were very detailed. (You may need to access it at an institutional library).
Often in-depth descriptions were given of living and working conditions. You can find lists of infectious disease outbreaks around the country and later most hospital published regular reports.
However it is not the place most would expect to be of direct genealogical value but you would be mistaken.
“Oh, you mean it has information about Doctors but I don’t have any of them in my family.”
Yes, it is true there is a lot of biographical information about doctors in the British Medical Journal (and the Medical Journals of other countries). It has information about where they trained, where they practised and this might be anywhere in the world. Often there are entries of births, marriages and deaths as well as lists of promotions particularly during war time. Note: this is true of many professional or trade journals so well worth a look.
The privacy concerns of today were not in evidence in the past regarding patients. Many case (patient) reports in the past gave the full name, age and town of residence! Be prepared for some fairly blunt descriptions of the patients as well.
