Care Pathway Simulator
Winner of the HITEA Award for Best Use of IT in the Health Service 2005
The principle of continuous quality improvement (CQI) in healthcare is that health care delivery must be constantly reviewed, assessed and improved. Widely used "suck it and see" methods such as PDSA (plan-study-do-act) are insufficient to cope with the pace of change and designing complex systems: more robust techniques are needed. Process design is a well understood subject and modern computer-based process simulation and design tools have revolutionised manufacturing industry. However these tools are not designed for use in patient-centred care processes and to-date have had very little impact in healthcare. A new tool has recently been developed specifically for use in healthcare (Care Pathway Simulator, SAASoft Ltd UK) and has been used to assist the redesign of the Vascular Surgery One Stop Clinic at Good Hope Hospital. Specifically CPS was used to test proposed clinic booking schedules that were designed to minimise patient waiting, reduce the number of clinic overruns and maximise clinic capacity. The final solution was implemented as a simple paper-based booking schedule that increases maximum capacity by 40% - this new schedule has been in use for over 9 months and has performed as predicted by the computer simulation. In effect we have achieved a win-win-win outcome: a better service for patients, reduced stress for staff, and increased capacity to provide resilience to cope with unpredictable changes in demand.

Leg Ulcer Telemedicine System
Winner of NHS Innovation Award for Service Delivery 2004
Leg ulcers affect around 0.2% of the population, most of who are elderly, with direct treatment costs in the region of £500 M per year in the UK alone. The high cost of leg ulcers is mainly due to repeated dressing by community nurses over extended periods of time, often many years. Any means to accelerate healing time and reduce ulcer recurrence will therefore result in quality of life improvement for the patients and their carers and major cost savings for the NHS. Over 80% of leg ulcers are due to vascular disease and treatment should be based on an accurate diagnosis that requires expert assessment in a specialist unit with direct access to duplex ultrasound. Treatment in the community by specially trained nurses is more acceptable to patients and reduces the burden on busy hospital outpatient departments. Thus, optimum management requires close cooperation between the hospital and community-based specialists.
Following an initial audit of the Good Hope Hospital vascular outpatient clinic, two changes in the existing care process were implemented:
Following the implementation of the OSC, the time from referral to a definitive management plan was reduced from 24 weeks to 4 weeks and the average number of repeat hospital visits was reduced from six to five.
Following the addition of the EPR system, the time from referral to definitive treatment plan was reduced to 2 weeks and the average number of repeat hospital visits reduced from five to two.
Despite the initial reservations, we found that the EPR system was enthusiastically adopted by the community nursing teams once they had direct experience of real benefits for their patients.
The problems with the implementation an EPR were a lack of appropriate software that met the essential functional and non-functional requirements, and the resistance to change of both hospital and community staff. These hurdles were overcome by development of a dedicated client-server software application and the provision of extensive familiarisation, training and hands on experience of the system for the community and hospital teams. The community nurse teams were encouraged to visit the OSC and experience first-hand how the whole care process works before using the EPR system in the community. A randomised controlled trial (RCT) is now underway to compare the conventional paper-based care process with the EPR system and we are also running a number of advanced study days for the local community nurses to provide an introduction to these new models of care.
The OSC/EPR shared care model for leg ulcers has provided a number of benefits.
Our experience in the successful design and implementation of this OSC/EPR system has taught us a number of valuable lessons:
