7-day doctors cut weekend emergency hospital visits by 18 percent, study finds
The UK Government's pilot of seven-day opening of doctor surgeries has significantly reduced weekend emergency hospital visits, hospital admissions and ambulance call-outs, new University of Sussex research has found.
Spread across the whole week, Accident & Emergency visits were down 10 per cent among patients of pilot surgeries in central London. The greatest effect was seen on Saturdays and Sundays, with a drop of 18 per cent recorded across weekends.
Crucially, for squeezed NHS budgets, expensive hospital stays and ambulance call-outs also dropped significantly. The reductions were almost entirely driven by fewer elderly patients with moderate injuries or illnesses – not, as the Government expected, by minor cases being diverted away from A&E.
The researchers believe this is because A&E doctors take fewer risks with elderly patients they don't know and choose to admit them to a ward to be 'on the safe side', whereas General Practitioners (GPs) have an intimate knowledge of their patients' medical history and can send the less serious cases home after treatment. Essentially, GPs make far more effective 'gatekeepers' to more expensive treatments.
Many of the minor cases in A&E are the so-called frequent flyers – people who visit A&E on multiple occasions. Very few of these people took up the option to visit a GP instead.
This suggests that a nationwide roll-out of seven-day opening would not only reduce pressure on stretched A&E services as a whole, but that the impact would be biggest among the most costly cases.
Professor Peter Dolton and Dr Vikram Pathania of Sussex's School of Business, Management and Economics led the study, which is published online in the Journal of Health Economics.
Dr Pathania said: "There is clearly evidence of unmet demand for weekend GP opening.
"Seven-day opening for GPs appears to make a dent in two major sources of A&E expense – admissions and ambulance usage. The latter alone shows a significant drop of nearly 20 per cent on weekends.
"Costs aside, there is also strong evidence that patient healthcare, in many cases, could be better delivered by a visit to a GP.
"Patients may automatically equate the size and complexity of a large hospital-based A&E unit with higher quality care. But typically A&E doctors are junior to GPs, who are equivalent to hospital consultants in terms of their medical training and expertise. Plus GP treatment is based on direct past experience with the patient and access to their medical records."
The research has potentially large implications for NHS finances, with an unplanned hospital admission costing around 30 times as much as a GP visit:
- A&E visits have risen 32 per cent over the past decade to 21.8 million a year
- Each A&E visit costs the NHS £114
- An ambulance call-out adds £220 to the bill
- An unplanned hospital admission costs an eye-watering £1489
- This compares to just £45 for the average GP visit
The researchers caution that the long-term impacts are still unknown. People may respond to less crowded A&Es by visiting them more, for example.
It is also clear that demand is highest among older people and, as the research also shows, the more affluent. In fact, some practices have already curtailed their weekend opening, citing insufficient demand.
It may be, therefore, that seven-day opening should only be implemented in strategically located surgeries and may not be optimal for all surgeries.
Professor Dolton said: "These findings suggest the need for a careful rethink about the efficiency of redirecting patients to extended GP surgeries to lighten the load in A&E – although this would need to be accompanied by a redirection of NHS funding to Primary Care."
