At Guys and St Thomas's NHS Foundation Trust Andrew Williams, Consultant Colorectal Surgeon has implemented the 'Enhanced Recovery Programme'. Prior to undergoing major surgery patients have their anaerobic threshold measured, and are given carbohydrate enriched drinks to 'carbo load' and prepare the body for the stress of major surgery. During surgery minimally invasive techniques are used as well as oesophageal Doppler monitoring using the CardioQ. Following surgery the patient is encouraged to get out of bed on the day of surgery and allowed to eat and drink immediately, and is again given carbohydrate enriched drinks to assist recovery. Once discharged the patient has a telephone follow up with the Enhanced Recovery nurse to provide support for their rehabilitation.

The Colorectal Surgery Department at Guys and St Thomas' has seen length of stay fall from a mean of 17 days to just 10.7 days across all elective colorectal surgery irrespective of magnitude of surgery or medical co-morbidity.

The Medway Maritime NHS Trust in Kent was the first Trust to adopt the CardioQ technology on day to day surgery on a wide scale in 2004. It has reported potential savings of £3 million a year from using the technology and is already saving over £1 million per year. Medway was able to close 1.5 surgical wards partly as a result of the use of CardioQ and aims to open a 10 bed surgical High Dependency Unit in part of the space freed up. Andy Horne, the hospital's Chief Executive commented, "we have used CardioQ in around 200 operations in the last four months and had very good results. It has improved quality of care for patients as they are healthier when they leave theatre, need less post-operative care and get home quicker".

The study conducted at the Royal Alexandra Hospital by Dr David Alcorn and his team in May 2006 involved 30 patients undergoing major colorectal surgery and aimed to discover whether patients' lengths of stay in hospital after surgery were reduced if their fluid status was optimised during surgery. It found that those patients who were treated with CardioQ had a mean length of stay of 9.55 days compared to 12 days for those patients that had received a standardised anaesthetic. This equates to a 20% reduction in the average length of post-operative hospital bed stay. Dr David Alcorn, a Consultant Anaesthetist, who was in charge of auditing the procedure at the hospital said, "we are greatly encouraged by the results achieved. This has major benefits not only for patients but for clinicians and hospitals throughout the country".
