New American Academy of Orthopaedic Surgeons (AAOS) criteria specify when it may be appropriate to consider antibiotic administration prior to various dental procedures to prevent infection of an orthopaedic replacement joints or implants. “Appropriate Use Criteria (AUC) for the Management of Patients with Orthopaedic Implants Undergoing Dental Procedures” was recently approved by the AAOS Board of Directors.
Most patients with replacement hip, knee, shoulder or other implants, are not at risk for infection following dental procedures. However, there are a small number of patients those with severely compromised immune systems due to AIDS, uncontrolled diabetes or chemotherapy; a recent history of joint infections; and/or patients taking specific drugs for rheumatoid arthritis or to prevent organ transplant complications who should receive consideration for antibiotic administration prior to dental procedures. In these patients, infection may occur during the procedure when bacteria travel through the blood stream to the implant, which cannot fight off disease or infection. A severe infection will most likely require surgery at the site of the implant infection, and may even cause death.
Because infections can be so dangerous, “surgeons and dentists prefer to err on the side of caution in the most high-risk patients,” said Robert H. Quinn, MD, AUC section leader, AAOS Committee on Evidence-Based Quality and Value. And yet, antibiotic overuse throughout the health care system has made many types of bacteria resistant to treatment.
“These guidelines will hopefully help to decrease antibiotic use in patients with artificial joints, but still provide reasonable scenarios when they might be considered,” said Dr. Quinn.
The AUC, available through the AAOS Ortho Guidelines website and app, includes questions for clinicians to gauge risk related to the type of dental procedure, given the patient’s implant status and overall health. There are 64 scenarios, each with an antibiotic “appropriateness rating” from 1 to 9, determined by a 14-member voting panel of orthopaedic surgeons, dentists, oral surgeons and epidemiologists. A rating between 7 and 9 means that antibiotic use is “appropriate for the indication provide and is likely to improve the patient’s health outcomes or survival.” With a rating of 4 to 6, antibiotics “may be appropriate;” and 1 to 3, “rarely appropriate.” Specific antibiotics and dosage are provided for scenarios when antibiotic treatment is recommended.
