By the 1930's Selly Oak Hospital had a mixture of purpose built wards and converted workhouse buildings. The older converted blocks were not really suitable for patient care they had narrow winding corridors with a number of small side rooms for up to 4 patients, but were used to increase the total number of beds available The newer wards were of the type developed from the recommendations of Florence Nightingale hence known as "Nightingale wards", they are the traditional image we see of a ward it would be long and narrow suitable for up to 40 beds, well lit and ventilated, and laid out to be practicable for patient care.
As this was still the early days of medicine and surgery, care would not be as complex as today and the majority of patients would be for palliative care just as a hospice today. Many would be long stay, my grand father was in for over 12 months and my late father-in-law for nearly 2 years.
