North West Anglia NHS Trust was hit hard by winter pressures this year, figures show. NHS England data, from December 3 last year to March 3, has revealed how acute hospital trusts coped over the colder months, based on occupancy levels and other key indicators. General and acute wards at North West Anglia NHS Foundation Trust were 93.9 per cent full on average, well above the safe limit of 85 per cent recommended by the British Medical Association. On its busiest day, occupancy hit 98.8 per cent. Across England, average occupancy was 93.5 per cent. According to NHS Improvement, occupancy rates of 92 per cent and above lead to significantly worse A&E performance. The trust looks after Hinchingbrooke Hospital, Peterborough Hospital, and Stamford and Rutland Hospitals. Dr Nick Scriven, president of the Society for Acute Medicine, said it was unacceptable to continue to expect hospitals to manage on shoestring budgets and with depleting workforces. He said: For those working at the sharp end of the NHS the figures are no shock. Our hospitals have been on a knife edge for more than 18 months now, with staff run ragged trying to keep them safe. We have seen a year-on-year reduction in the beds available to care for acutely unwell people in hospitals, despite an ever-increasing need from an ageing population. On average, there were 40 escalation beds in use each day at North West Anglia NHS Trust. These are temporary beds set up during periods of intense demand, often in corridors or day care centres. Staff opened 66 such beds when pressure was at its highest. According to healthcare workers union Unison, cuts to social care budgets have led to a growing problem of long-stay patients - which can impact the ability of hospitals to accommodate urgent admissions. On a typical day at North West Anglia NHS Trust, 335 patients had been in hospital for a week or more, taking up more than 40 per cent of all occupied beds. Of these, an average of 102 patients had been in hospital for at least three weeks. Unison head of health, Sara Gorton, said: Although this winters weather has been relatively mild, there has been no let-up in the pressures facing patients and staff, laying bare serious underlying problems. She added: Meanwhile, ambulance crews are tied up with handover delays rather than being where they and the public want them to be - responding to 999 calls and saving lives. A total of 12,688 patients were taken by ambulances to North West Anglia NHS Trust over the winter months. Delays left 2,968 patients waiting 30 minutes or more before they could be transferred to the care of A&E staff - almost a quarter of all arrivals. Of those, 811 patients waited for more than an hour before they were admitted. The NHS says a delay of just 15 minutes is a potential threat to life. NHS England insisted ambulance services were improving, with crews responding to life threatening calls faster and experiencing fewer delays at A&E. It added that staff has been working incredibly hard throughout winter to provide the best care for patients.Simon Evans, interim chief operating officer at North West Anglia NHS Foundation Trust, which runs Peterborough City, Hinchingbrooke and Stamford and Rutland Hospitals, said: We have robust plans in place across all of our hospital sites to ensure we are able to cope with the increased pressures that the winter season brings. This includes increasing staffing levels where appropriate, working with our colleagues in community healthcare and local authority to ensure we can discharge patients safely and efficiently. We do continue to encourage the general public to be mindful of their treatment options so we dont have an influx of emergency department admissions if care for minor injuries or ailments can be sought elsewhere. It is not just emergency admissions that can tip the balance over the winter period. In the last few years, we have seen a continued rise in the acuity of our patients meaning they are much sicker and need to stay in hospital longer. When this happens patients do sometimes wait longer than we would like to access services, as we prioritise those sickest patients. However, we have increased the number of beds we have at both Peterborough City and Hinchingbrooke Hospitals so we can cope better with the increased demand for inpatient admissions.
