Do we practice evidence based medicine with regard to drain usage in knee arthroplasty? Results of a questionnaire of BASK members

Clinical governance requires our clinical practice to be evidence based. We wished to see if British Orthopaedic surgeons are using the current evidence with regards to the use of drains in knee arthroplasty. A questionnaire was faxed to all UK members of BASK to ascertain their current practice regarding the use of drains in knee arthroplasty and the rationale for their drain policy. The study suggests that the majority of practising members of BASK do not practice evidence based medicine with regard to the use of drains in knee arthroplasty.
