Abstract
It has been proposed that scoring systems could be nationally used, initially on a secondary care level as a method of prioritising patients on waiting lists for hip and knee arthroplasty. If this were to be successful, scoring systems could be used as a way of tackling the ever increasing waiting list times for surgery which currently stand at around 15 months on the NHS.
I studied and compared the New Zealand and Oxford Hip and Knee Scores, collecting data from 79 patients over a period of seven weeks.
I found that generally, patients who scored highly were recommended for surgery; however I also found that in the group of patients recommended for surgery there was a wide range of scores obtained. There was also a great deal of overlap between the scores obtained by those who were recommended for surgery and those who were not. This means that it would be very difficult to predict a decision for an individual patient based purely on their scores. In addition, many confounding variables can affect the wide range of scores obtained.
I concluded that there was too much variation between the scores obtained by patients undergoing surgery to be able to consistently and fairly prioritise them. In order to implement the use of scoring systems in this country, nationally approved criteria and priority banding categories need to be established. Scoring systems need to be modified to be clearer and to cover more variables. Larger studies need to be conducted with more patients and over a longer period of time; and further work could be done into the proposal that GP’s could use these systems as a tool for referral to consultant out-patient clinics.
