Background: The UK National Institute for Clinical Excellence (NICE) has
recommended the use of the new oral anticoagulant Xarelto® (rivaroxaban) over
injectable low molecular weight heparin (LMWH) in adults undergoing elective hip or
knee arthroplasty surgery. Aim: To assess patients’ perception of use of oral
anticoagulation versus injectable LMWH therapy after hip and knee arthroplasty.
Materials And Methods: A survey was conducted between August 2009 and
November 2009 of 50 patients (age range, 35 - 84 years, mean 65 years) receiving
injectable LMWH for VTE prophylaxis after total hip and knee replacement surgery.
The survey focused on preference, compliance, efficacy and safetyResults: A
significantly larger proportion preferred tablet prophylaxis to injections postoperatively
(68% Vs 26%). Older patients preferred tablets while younger patients preferred
injections (mean age 66.7 yrs vs. 61.7 yrs). Of the patients who preferred injection
prophylaxis, perceived compliance with tablet prophylaxis was less likely than
injections (38.46% Vs 53.85 %,). In those favouring tablet prophylaxis, a significantly
greater number of patients felt they would be compliant (82% vs. 18%), despite these
same patients perceiving injections as more clinically efficacious than tablets
(67.65% vs. 14.70%). Perception on safety between both methods was similar.
Conclusion: Our sample preferred oral anticoagulation following arthroplasty surgery.
However patients should be given an informed choice of anticoagulation as
differences in age and preference may affect compliance
