Editor—Smith ponders how acute hospital services are best organised.1 Current proposals commend hospitals and networks serving populations of 500 0002; Smith writes that the evidence that hospitals of such size are necessary to ensure high quality care is moderate for some surgical services but unclear for medical services.
But evidence in the surgical and oncological literature shows that outcomes of malignant diseases are better when patients are looked after by specialist teams rather than generalists. Similar evidence applies to joint replacement, treatment of fractured neck of femur and urological conditions, and vascular surgery.
Medical emergencies are a large part of care in most acute general hospitals in the United Kingdom. It was to deal with these that Andy Black devised his model (described by Smith), whereby patients would be first admitted to a local small hospital that would, in effect, be an assessment arm of the big hospital.
Studies in the past 10 years across the range of medical emergencies have shown better care in terms of process and outcome for asthma,3 gastrointestinal haemorrhage,4 ischaemic heart disease,5 stroke, and rehabilitation in acutely ill elderly patients. Delay in implementing optimal management in such conditions can affect outcome.
As well as achieving better outcomes, specialist teams also achieve more precise diagnosis. In the respiratory field in our hospital, patients with chronic obstructive pulmonary disease or the hyperventilation syndrome are misdiagnosed as having asthma almost daily. If they were not transferred to the specialist team they would receive inappropriate management and unnecessary drug treatment. In the present state of health service resourcing, the appropriate range and number of specialists and specialist teams can only be provided in a reasonably large acute general hospital.
The tension between access and quality that exists in any healthcare system is aggravated when that system is seriously under-resourced. Innovative suggestions such as that of Black need to be tested in trials. Such trials need to evaluate not only clinical outcomes and access but also costs and effective use of resources.
Doctors working in hospitals expect to base their practice on published evidence from basic and clinical science. We should expect the same of planners. The NHS provides a wonderful, and underused, testbed for the evaluation of different models of healthcare delivery.
