Newer infection prevention techniques , such as preoperative antiseptic scrubbing , are affected and may help reduce the infection rate , while traditionally accepted methods of prophylaxis such as laminar-flow operating rooms and body exhaust suits may raise the infection rate
Despite advances in our underst and ing of surgical site infections following total joint arthroplasty , this serious surgical complication continues to represent a substantial economic burden for the patient , the treating institution and the healthcare system .
After increasing for the past decade , infection rates have stabilized at 1.6 % ; however , the total cost is projected to increase with the total number of revision procedures performed .
Dental procedures as risk factors for prosthetic hip or knee infection: a hospital-based prospective case-control study.
BACKGROUND The actual risk of prosthetic joint infection as a result of dental procedures and the role of antibiotic prophylaxis have not been defined . METHODS To examine the association between dental procedures with or without antibiotic prophylaxis and prosthetic hip or knee infection , a prospect i ve , single-center , case-control study for the period 2001 - 2006 was performed at a 1200-bed tertiary care hospital in Rochester , Minnesota . Case patients were patients hospitalized with total hip or knee infection . Control subjects were patients who underwent a total hip or knee arthroplasty but without a prosthetic joint infection who were hospitalized during the same period on the same orthopedic floor . Data regarding demographic features and potential risk factors were collected . Logistic regression was used to assess the association of variables with the odds of infection . RESULTS A total of 339 case patients and 339 control subjects were enrolled in the study . There was no increased risk of prosthetic hip or knee infection for patients undergoing a high-risk or low-risk dental procedure who were not administered antibiotic prophylaxis ( adjusted odds ratio [ OR ] , 0.8 ; 95 % confidence interval [ CI ] , 0.4 - 1.6 ) , compared with the risk for patients not undergoing a dental procedure ( adjusted OR , 0.6 ; 95 % CI , 0.4 - 1.1 ) respectively . Antibiotic prophylaxis in high-risk or low-risk dental procedures did not decrease the risk of subsequent total hip or knee infection ( adjusted OR , 0.9 [ 95 % CI , 0.5 - 1.6 ] and 1.2 [ 95 % CI , 0.7 - 2.2 ] , respectively ) . CONCLUSIONS Dental procedures were not risk factors for subsequent total hip or knee infection . The use of antibiotic prophylaxis prior to dental procedures did not decrease the risk of subsequent total hip or knee infection
