Resources for the seven day services may be better spent on other NHS priorities
The NHS could achieve up to twice as much with the resources that the Government plans to spend introducing a full seven day service in the NHS in England, according to new research from The University of Manchester.
Health economists, working with colleagues at the University of York, have used official data to suggest an extra 5,353 deaths each year occur when people are admitted to hospital at the weekend rather than mid-week, but that the £1.43 billion cost of removing this risk would be better spent on other priorities.
Despite a seven day health service being a major priority, few studies have analysed the costs and benefits of implementing this provision fully. It is known that compared to midweek emergency admissions, patients who are hospitalised on a Saturday are 11% more likely to die and 16% more likely to die when admitted on a Sunday.
Part of the reason is thought to be the reduced availability of senior clinical staff at weekends.
Professor Matt Sutton, from The University of Manchester's Institute of Population Health led the study. He said: "Our estimates show the cost of implementing seven day services in this part of the NHS could be more than double what the official guidance recommends.
"These are likely to be over-estimates. It is highly unlikely that all additional risk to patients would be eliminated and moving consultants and other resources from some days may just move the problem to a different point in the week. Recruiting and training more senior staff will add to costs significantly."
The estimates were based on mortality figures within 30 days of admission between 1 April 2010 and 31 March 2011. Cost estimates were benchmarked against the National Institute of Health and Care Excellence (NICE) standard, which recommends a maximum spend of £20,000 per quality-adjusted life year gained by making a change to a service.
Quality-adjusted life years (QALYs) are a measure of the quality and quantity of life gained which are used to evaluate the cost-effectiveness of healthcare interventions. The most which could be spent under NICE guidelines to gain the estimated 36,539 QALYs would be £831m, almost half the amount that the NHS has estimated that seven day services will cost to implement.
The researchers suggest that more work needs to be done to identify smaller scale changes that might be cost-effective. For example, the additional weekend risk for renal failure is 37%, but for pneumonia it is zero.
Rachel Meacock, the lead author, said: "Funders of healthcare need to make decisions as to where money goes so that it can do most good. The figures we've produced in this research would indicate that a blanket approach to removing the risk of weekends might not be the most effective way for the NHS to spend almost £1.5 billion."
