Unnecessary magnetic resonance imaging of the knee: How much is it really costing the NHS?


ABSTRACT:

Aims and objectives

The aim of this study was to evaluate the indications for patients undergoing magnetic resonance imaging (MRI) of the knee prior to referral to an orthopaedic specialist and to ascertain whether these scans altered initial management.

Materials and method

A retrospective review of all referrals received by a single specialist knee surgeon over a 1-year period was performed. Patient demographics, relevant history, examination findings and past surgical procedures were documented. Patients having undergone Magnetic resonance imaging (MRI) prior to referral were identified and indications for the scans recorded. These were reviewed against The National health services (NHS) guidelines for Primary Care Physicians to identify if the imaging performed was appropriate in each case.

Results

A total of two sixty-one (261) patients were referred between 1st July 2018 and 30th June 2019. Eight seven out of two hundred and sixty-one patients (87/261) patients underwent knee MRI prior to referral. The average patient age was 53 years with male predominance (52 verses 35 females). Twenty-one out of eight seven patients under review (24%) underwent appropriate imaging prior to referral as per guidelines. However, only thirteen percent of patients underwent plain radiograph of knee before their scan. In cases where magnetic resonance imaging was not indicated, patients waited an average of twelve weeks between their scan and for a referral to be sent to a knee surgeon.

Conclusion

Seventy six percent of patients referred to orthopaedics had inappropriate Magnetic resonance imaging arranged by their primary care physician. For a single consultant's referrals over 1 year these unnecessary MRI (magnetic resonance imaging) of knee cost National Health Services (NHS) £13,200. Closer adherence to the guidelines by primary care physicians will result in a financial saving, better patient experience and a more effective use of resources.
