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 .
Efficacy of surgical preparation solutions in shoulder surgery.
BACKGROUND Deep infection following shoulder surgery is a rare but devastating problem . The use of an effective skin-preparation solution may be an important step in preventing infection . The purpose s of the present study were to examine the native bacteria around the shoulder and to determine the efficacy of three different surgical skin-preparation solutions on the eradication of bacteria from the shoulder . METHODS A prospect i ve study was undertaken to evaluate 150 consecutive patients undergoing shoulder surgery at one institution . Each shoulder was prepared with one of three r and omly selected solutions : ChloraPrep ( 2 % chlorhexidine gluconate and 70 % isopropyl alcohol ) , DuraPrep ( 0.7 % iodophor and 74 % isopropyl alcohol ) , or povidone-iodine scrub and paint ( 0.75 % iodine scrub and 1.0 % iodine paint ) . Aerobic and anaerobic cultures were obtained prior to skin preparation for the first twenty patients , to determine the native bacteria around the shoulder , and following skin preparation for all patients . RESULTS Coagulase-negative Staphylococcus and Propionibacterium acnes were the most commonly isolated organisms prior to skin preparation . The overall rate of positive cultures was 31 % in the povidone-iodine group , 19 % in the DuraPrep group , and 7 % in the ChloraPrep group . The positive culture rate for the ChloraPrep group was lower than that for the povidone-iodine group ( p < 0.0001 ) and the DuraPrep group ( p = 0.01 ) . ChloraPrep and DuraPrep were more effective than povidone-iodine in eliminating coagulase-negative Staphylococcus from the shoulder region ( p < 0.001 for both ) . No significant difference was detected among the agents in their ability to eliminate Propionibacterium acnes from the shoulder region . No infections occurred in any of the patients treated in this study at a minimum of ten months of follow-up . CONCLUSIONS ChloraPrep is more effective than DuraPrep and povidone-iodine at eliminating overall bacteria from the shoulder region . Both ChloraPrep and DuraPrep are more effective than povidone-iodine at eliminating coagulase-negative Staphylococcus from the shoulder
