Use of LiDCO's technology has been shown to significantly reduce the complications (particularly infections) and costs associated with major surgery. The technology was invented in the Department of Applied Physiology based at St Thomas' Hospital, London where the Company maintains a research base. The Company's manufacturing facility is in London, UK and its current products are: • LiDCOplus and PulseCO monitors: computer-based platforms for displaying a range of real-time, continuous hemodynamic parameters including cardiac output, oxygen delivery and fluid volume; • LiDCO disposables: used in conjunction with the LiDCOplus Monitor to accurately determine cardiac output in a minimally-invasive manner. Distribution Network: The Company has now achieved registration of its products in 13 markets in Europe, the USA, Brazil and Japan. It sells direct to the NHS in the UK, and through a worldwide network of specialty critical care distributors. Background to the recently published clinical trial: Better than standard care - (Early Good Directed Therapy) improves outcome in high risk surgery patients: The results of a major trial at St George's Hospital, London using LiDCO's minimally invasive monitoring technology were presented during the 25th International Symposium on Intensive Care and Emergency Medicine in Brussels (21st to 25th March). The results have revealed the following: a) Savings in the cost of treating patients amounting to an average of £4,000 per patient. Extrapolated nationally, this would equate to a estimated saving of £500 million per annum for the NHS b) The monetary saving (£248,000) - resulted from 640 hospital days saved for 62 patients, an average of more than 10 bed days per patient c) The savings in cost and hospital days were associated with a significant reduction in medical complications (particularly infections) through the use of LiDCO's minimally invasive technology to improve tissue oxygen levels following surgery.
