However, a new study by academics at the Universities of Birmingham, Warwick and Leicester calls this assumption into doubt. The research concludes that although there is less direct consultant involvement in the care of people admitted to hospital as an emergency at weekends than on a weekday, there does not seem to be any direct link between weekend consultant staffing and the risk of dying following an emergency admission . Policy makers should therefore be cautious about attributing the ‘weekend effect’ solely to a lack of consultant staff when implementing seven-day services.
