Statistical data relating factors such as delay, distance travelled, surgical skill and size of hospital to the outcome of operations are not at present available. It is doubtful if it would be possible to measure some of these factors in a way that would enable meaningful deductions to be made. For example there are many aspects of the problem of delay and an attempt to measure the initial delay in calling on medical advice is not likely to give reliable results. Surgical skill would obviously be very difficult to quantify.
The hospital in-patient survey, which is being undertaken by the Medico-Social Research Board, will provide a wide range of information about hospital in-patients including data such as distance of the hospital from patient's home and the size of the hospital. At present this survey is in its early stages of development. When it is more fully developed it will provide information of great value in many directions but particularly for the purpose of research into many aspects of morbidity and mortality.
