The delivery of health care has become increasingly complex, and most clinical research focuses on new approaches to diagnosis and treatment. There have been significant advances in medical technology used in patient treatment and care. The Intensive Care Unit (ICU) in an acute hospital is designed to treat the most complex and unstable medical and surgical patient. Most ICU admissions occur because the patient requires technology that is available only within the ICU for monitoring or therapeutic purposes (Scales et al, 2004) . In the past decade, the medical technology and systems used in Intensive Care Units have become significantly more sophisticated. A typical ICU would have immediate access to core technologies such as respiratory ventilators, physiological and cardiac monitoring, infusion/ management systems, and blood gas analysers. Additional equipment such as non-invasive ventilators, cardiac defribrillators, imaging systems and pathology services would also be routinely used in response to individual patient requirements. Teams of highly trained professionals use technology as an integral part of their work in the ICU. These include medical intensivists, critical care nurses, clinical pharmacists, physiotherapists, dieticians, medical and surgical specialties, and personnel from a range of supporting specialties such as Laboratory, and Radiology.
In the past decade, the risk of harm caused by medical care has received increasing scrutiny (Bates et al, 2003) . Almost every major industry has used advances in information technology to increase work productivity and improve safety. Similarly, the medical literature is increasingly supporting the view that the greatest improvements in patient care and safety are through approaches that allow best use of the medical data available, to perfect existing techniques of evaluation and care, rather than the introduction of new technologies alone. Breslow et al (2005) describe how Information Technology tools offer greater potential to enhance the quality and safety of patient care and increase provider effectiveness.
A Clinical Information System (CIS) is an example of such technology. A CIS was first defined by Morris (1988) as a means to integrate clinical information at the point-of-care. A CIS allows the capture of the entire patient generated clinical and physiological data, and present it in a form that makes it available as useful information. The real power of the CIS, which facilitates real patient benefits, is that it can become a clinical decision support tool that supports evidence based practice. There are many published examples on how such a methodology directs patient care through implementing patient treatment protocols, and managing all sources of patient data generated at the point of care (Gardner 1998) .
A major capital development programme commenced at the University College Hospital Galway in 2000, and included the provision of a state-of-the-art 27-bed critical care service, which includes a 12 bed General Medical and Surgical ICU. A project Team was formed, which included personnel from the ICU, to equip the unit with medical equipment. This included the installation of a CIS to the 12-bed ICU, with provision to expand the system to the 27-bed compliment of the critical care services at UCHG.
At the time of writing, the CIS has been in use for 5 months. This paper will explore the equipping process undertaken at UCHG; the initial proposal for funding, the tender evaluation process, and the implementation phase of the project. It will also give an account of the clinical experiences with the system, why the project was successful, and how the ICU plans to develop the system further and use it to help direct an evidence based approach to the care of the critically ill patient....
