An estimated third of rheumatologists send aspirated synovial fluid samples for culture routinely during the course of management of their patients irrespective of the underlying diagnosis.
This is done apparently even when sepsis is not suspected.
This audit of 507 synovial fluid culture requests revealed that positive bacterial growth was rare even when sepsis was queried on the request forms but none was positive in any of the routine samples.
Our findings throw doubt on the value of routine synovial fluid culture.
We recommend that such cultures are undertaken when infection is a possibility and in immuno-compromised patients.
An average health district would save £3000 per annum if such a policy was adopted, but across the National Health Service as a whole the total expenditure saved on this unnecessary investigation would be considerable.
