In the first such collaboration of its kind, an expert panel of rheumatologists and orthopaedic surgeons has developed guidelines for the perioperative management of anti-rheumatic medication in patients undergoing total hip or knee replacement.
"Patients with rheumatic diseases who have joint replacement surgery are at increased risk for joint infection, a potentially devastating complication," said Susan Goodman, MD, co-principal investigator and a rheumatologist at Hospital for Special Surgery in New York City. "As infection risk is linked to the use of anti-rheumatic medication, our goal was to develop recommendations on when to stop medication prior to joint replacement and the optimal time for patients to restart treatment after surgery. Appropriate medication management in the perioperative period may provide an important opportunity to lower the risk of an infection or other adverse outcome."
The expert panel consisted of 31 specialists from more than 20 hospitals and professional organizations. The medication guidelines concern adults with rheumatoid arthritis; spondyloarthritis, including ankylosing spondylitis and psoriatic arthritis; juvenile idiopathic arthritis; and lupus undergoing hip or knee replacement.
The study included traditional disease-modifying anti-rheumatic drugs (DMARDs), biologic agents, tofacitinib, and glucocorticoids. The panel developed guidelines on when to continue, when to withhold, and when to restart these medications, as well as the optimal perioperative dosing of corticosteroids.
Among the main recommendations:
- Non-biologic DMARDs may be continued throughout the perioperative period in patients with rheumatoid arthritis, spondyloarthritis, juvenile idiopathic arthritis and lupus undergoing elective hip or knee replacement.
- Biologic medications should be withheld as close to one dosing cycle as scheduling permits prior to elective hip or knee replacement and restarted after evidence of wound healing, typically 14 days, for all patients with rheumatic diseases.
The patient panel, which had significant input, attached far greater importance to preventing infection at the time of surgery than to the possibility of a disease flare from stopping medication.
"The recommendations are intended for use by clinicians, including orthopaedists, rheumatologists, and other physicians performing risk assessment and evaluation, as well as by patients," Dr. Goodman noted. "Communication is key. It is imperative that open and informed communication between the patient, orthopaedic surgeon and rheumatologist take place."
