Toolkit for discussing antibiotics with patients who have orthopaedic implants
January 07, 2013
The following is text from the Shared Decision Making Tool: An Aid to Help Balance Clinical Information and Treatment Options with Patient Preferences, authored by David S. Jevsevar, M.D., M.B.A.
This toolkit accompanied an article in the Jan. 7 issue of ADA News about the ADA/AAOS co-developed guideline on antibiotic prophylaxis for dental patients with joint replacement. Download the full tool (PDF), including its history.
Shared Decision Making Tool
A Shared Decision Making Tool promotes the collaborative decision making between patient and clinician for best treatment strategy. It is an additional tool to be used and supplements, but does not replace, informed consent procedures.
As a useful aid to the AAOS/ADA Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures clinical practice guideline, the Shared Decision Making Tool would engage patients in a decision making process and provide information to further clarify the risks, benefits and alternatives to treatment.
Should I take antibiotics before my dental procedure?
You have an orthopaedic implant (joint replacement, metal plates or rods, etc.) from a previous orthopaedic surgery.
• A potential complication of these implants is bacterial infection, which occurs in approximately 1-3 percent of patients. These infections require more surgery as well as antibiotic usage for an extended period of time. Most infections occur around the time of the procedure (within one year), but some have occurred much later.
• In theory, late implant infections are caused by the spread of the bacteria from the bloodstream to the implant. Unfortunately, there is no clear scientific evidence to support this theory. We know that many patients with orthopaedic implants frequently have bacteria in their blood that does not spread to their implants.
Dental procedures have long been considered a potential cause of implant infections even after the initial orthopedic postoperative period.
This is because dental procedures can introduce bacteria from the mouth into the bloodstream. However, this fact should be considered in the context that eating and performing oral hygiene at home may also introduce oral bacteria into the blood.
• Traditionally, antibiotics have been provided prior to dental procedures in patients with orthopaedic implants to minimize the bacteria that get into the blood.
• Best evidence, however, does not show that antibiotics provided before oral care help prevent infections of orthopaedic implants.
• The routine use of antibiotics in this manner has potential side effects such as increased bacterial resistance, allergic reactions, diarrhea and may even cause death.
Patients who have compromised immune systems might be at greater risk for implant infections.
• Diabetes, rheumatoid arthritis, cancer, chemotherapy and chronic steroid use are examples suggesting immunosuppression. Please discuss your potential for immunosuppression with your physician or dentist.
• Patients who are immune-compromised might wish to consider antibiotics before dental procedures because of their greater risk for infection.
• Decisions with regard to antibiotic premedication should be made by patients, dentists and physicians in a context of open communication and informed consent.
