Quid du timing de lrsquoantibioprophylaxie

Timing of antimicrobial prophylaxis and the risk of surgical site infections results from the Trial to Reduce Antimicrobial

Prophylaxis Errors

Steinberg JP1 et al Ann Surg 2009

OBJECTIVE The objective of this study is to determine the optimal timing for surgical antimicrobial prophylaxis (AMP)

SUMMARY BACKGROUND DATA National AMP guidelines should be supported by evidence from large contemporary data sets

METHODS Twenty-nine hospitals prospectively obtained information on AMP from 4472 randomly selected cardiac hipknee

arthroplasty and hysterectomy cases Surgical site infections (SSIs) were ascertained through routine surveillance using National

Nosocomial Infections Surveillance system methodology The association between the prophylaxis timing and the occurrence of

SSI was assessed using conditional logistic regression (conditioning on hospital)

RESULTS One-hundred thirteen SSI were detected in 109 patients SSI risk increased incrementally as the interval of time

between antibiotic infusion and the incision increased (overall association between timing and infection risk P = 004) When

antibiotics requiring long infusion times (vancomycin and fluoroquinolones) were excluded the infection risk following

administration of antibiotic within 30 minutes prior to incision was 16 compared with 24 associated with administration of

antibiotic between 31 to 60 minutes prior to surgery (OR 174 95 confidence interval 098-304) The infection risk increased

as the time interval between preoperative antibiotic and incision increased or if the antibiotic was first infused after incision

(ORthinsp=thinsp220 95 CI 103-466) but not prior to 60 minutes Intraoperative redosing (performed in only 21 of long operations)

appeared to reduce SSI risk in operations lasting more than 4 hours (OR of 308 with no redosing 95 confidence interval 074-

1290) but only when the preoperative dose was given correctly

CONCLUSIONS These data from a large multicenter collaborative study confirm and extend previous observations and show a

consistent relationship between the timing of AMP and SSI risk with a trend toward lower risk occurring when AMP with

cephalosporins and other antibiotics with short infusion times were given within 30 minutes prior to incision

Impact of vancomycin surgical antibiotic prophylaxis on the development of methicillin-sensitive staphylococcus aureus surgical site infections report from Australian Surveillance Data (VICNISS) Bull AL1 Worth LJ Richards MJ Ann Surg 2012 OBJECTIVE To compare risks for developing surgical site infection (SSI) due to Staphylococcus aureus when vancomycin is used for antibiotic prophylaxis with risks when a β-lactam antibiotic is administered for prophylaxis BACKGROUND Vancomycin is often used as surgical antibiotic prophylaxis for major surgery In nonsurgical populations there is evidence that vancomycin is less effective for prevention and treatment of methicillin-sensitive Staphylococcus aureus (MSSA) infections Since 2002 the Victorian Healthcare Associated Surveillance System (VICNISS) has used standardized methods for infection surveillance in Australia including any prophylactic antibiotic agent administered before surgical procedures METHODS Surveillance records were obtained for patients undergoing 4 clean surgical procedures during the period of November 2002 to June 2009 Logistic regression analysis was used to examine risk factors for infection including age procedure duration American Society of Anesthesiologists score and choice and timing of antibiotic prophylaxis RESULTS The data set consisted of 22549 procedures including cardiac bypass and hip and knee arthroplasty procedures Vancomycin prophylaxis was administered in 1610 cases and a β-lactam antibiotic for 20939 cases A total of 754 SSIs were recorded The most frequent pathogens were MSSA methicillin-resistant Staphylococcus aureus and Pseudomonas species The adjusted odds ratio (OR) for an SSI with MSSA was 279 where vancomycin prophylaxis was administered (P lt 0001) For methicillin-resistant Staphylococcus aureus infection the adjusted OR for vancomycin was 044 (P = 005) whereas for Pseudomonas infection it was 096 (P = 095) CONCLUSIONS In a large Australian study population prophylaxis with vancomycin was found to be associated with an increased risk of SSI due to MSSA when compared with prophylaxis with a β-lactam antibiotic Given the potential for poorer surgical outcomes in the setting of indiscriminate prophylactic vancomycin use measures to improve adherence to guidelines for restricted administration of prophylactic vancomycin are supported

Conclusion

bull En cas de reprise de prothegravese infecteacutee la seule situation ougrave lrsquoadministration drsquoune antibioprophylaxie (agrave large spectre) semble neacutecessaire est celle ougrave lrsquoantibiotheacuterapie deacutebuteacutee en per-opeacuteratoire degraves les preacutelegravevements reacutealiseacutes ne semblent pas avoir un spectre suffisant pour couvrir les bacteacuteries reacutesistantes dont le patient pourrait ecirctre porteur suite agrave un seacutejour reacutecent dans un hocircpital ou un autre centre de soins

Impact of vancomycin surgical antibiotic prophylaxis on the development of methicillin-sensitive staphylococcus aureus surgical site infections report from Australian Surveillance Data (VICNISS) Bull AL1 Worth LJ Richards MJ Ann Surg 2012 OBJECTIVE To compare risks for developing surgical site infection (SSI) due to Staphylococcus aureus when vancomycin is used for antibiotic prophylaxis with risks when a β-lactam antibiotic is administered for prophylaxis BACKGROUND Vancomycin is often used as surgical antibiotic prophylaxis for major surgery In nonsurgical populations there is evidence that vancomycin is less effective for prevention and treatment of methicillin-sensitive Staphylococcus aureus (MSSA) infections Since 2002 the Victorian Healthcare Associated Surveillance System (VICNISS) has used standardized methods for infection surveillance in Australia including any prophylactic antibiotic agent administered before surgical procedures METHODS Surveillance records were obtained for patients undergoing 4 clean surgical procedures during the period of November 2002 to June 2009 Logistic regression analysis was used to examine risk factors for infection including age procedure duration American Society of Anesthesiologists score and choice and timing of antibiotic prophylaxis RESULTS The data set consisted of 22549 procedures including cardiac bypass and hip and knee arthroplasty procedures Vancomycin prophylaxis was administered in 1610 cases and a β-lactam antibiotic for 20939 cases A total of 754 SSIs were recorded The most frequent pathogens were MSSA methicillin-resistant Staphylococcus aureus and Pseudomonas species The adjusted odds ratio (OR) for an SSI with MSSA was 279 where vancomycin prophylaxis was administered (P lt 0001) For methicillin-resistant Staphylococcus aureus infection the adjusted OR for vancomycin was 044 (P = 005) whereas for Pseudomonas infection it was 096 (P = 095) CONCLUSIONS In a large Australian study population prophylaxis with vancomycin was found to be associated with an increased risk of SSI due to MSSA when compared with prophylaxis with a β-lactam antibiotic Given the potential for poorer surgical outcomes in the setting of indiscriminate prophylactic vancomycin use measures to improve adherence to guidelines for restricted administration of prophylactic vancomycin are supported

Timing of antimicrobial prophylaxis and the risk of surgical site infections results from the Trial to Reduce Antimicrobial

Prophylaxis Errors

Steinberg JP1 et al Ann Surg 2009

OBJECTIVE The objective of this study is to determine the optimal timing for surgical antimicrobial prophylaxis (AMP)

SUMMARY BACKGROUND DATA National AMP guidelines should be supported by evidence from large contemporary data sets

METHODS Twenty-nine hospitals prospectively obtained information on AMP from 4472 randomly selected cardiac hipknee

arthroplasty and hysterectomy cases Surgical site infections (SSIs) were ascertained through routine surveillance using National

Nosocomial Infections Surveillance system methodology The association between the prophylaxis timing and the occurrence of

SSI was assessed using conditional logistic regression (conditioning on hospital)

RESULTS One-hundred thirteen SSI were detected in 109 patients SSI risk increased incrementally as the interval of time

between antibiotic infusion and the incision increased (overall association between timing and infection risk P = 004) When

antibiotics requiring long infusion times (vancomycin and fluoroquinolones) were excluded the infection risk following

administration of antibiotic within 30 minutes prior to incision was 16 compared with 24 associated with administration of

antibiotic between 31 to 60 minutes prior to surgery (OR 174 95 confidence interval 098-304) The infection risk increased

as the time interval between preoperative antibiotic and incision increased or if the antibiotic was first infused after incision

(ORthinsp=thinsp220 95 CI 103-466) but not prior to 60 minutes Intraoperative redosing (performed in only 21 of long operations)

appeared to reduce SSI risk in operations lasting more than 4 hours (OR of 308 with no redosing 95 confidence interval 074-

1290) but only when the preoperative dose was given correctly

CONCLUSIONS These data from a large multicenter collaborative study confirm and extend previous observations and show a

consistent relationship between the timing of AMP and SSI risk with a trend toward lower risk occurring when AMP with

cephalosporins and other antibiotics with short infusion times were given within 30 minutes prior to incision

Timing of antimicrobial prophylaxis and the risk of surgical site infections results from the Trial to Reduce Antimicrobial

Prophylaxis Errors

Steinberg JP1 et al Ann Surg 2009

OBJECTIVE The objective of this study is to determine the optimal timing for surgical antimicrobial prophylaxis (AMP)

SUMMARY BACKGROUND DATA National AMP guidelines should be supported by evidence from large contemporary data sets

METHODS Twenty-nine hospitals prospectively obtained information on AMP from 4472 randomly selected cardiac hipknee

arthroplasty and hysterectomy cases Surgical site infections (SSIs) were ascertained through routine surveillance using National

Nosocomial Infections Surveillance system methodology The association between the prophylaxis timing and the occurrence of

SSI was assessed using conditional logistic regression (conditioning on hospital)

RESULTS One-hundred thirteen SSI were detected in 109 patients SSI risk increased incrementally as the interval of time

between antibiotic infusion and the incision increased (overall association between timing and infection risk P = 004) When

antibiotics requiring long infusion times (vancomycin and fluoroquinolones) were excluded the infection risk following

administration of antibiotic within 30 minutes prior to incision was 16 compared with 24 associated with administration of

antibiotic between 31 to 60 minutes prior to surgery (OR 174 95 confidence interval 098-304) The infection risk increased

as the time interval between preoperative antibiotic and incision increased or if the antibiotic was first infused after incision

(ORthinsp=thinsp220 95 CI 103-466) but not prior to 60 minutes Intraoperative redosing (performed in only 21 of long operations)

appeared to reduce SSI risk in operations lasting more than 4 hours (OR of 308 with no redosing 95 confidence interval 074-

1290) but only when the preoperative dose was given correctly

CONCLUSIONS These data from a large multicenter collaborative study confirm and extend previous observations and show a

consistent relationship between the timing of AMP and SSI risk with a trend toward lower risk occurring when AMP with

cephalosporins and other antibiotics with short infusion times were given within 30 minutes prior to incision

Quid du timing de lrsquoantibioprophylaxie

Timing of antimicrobial prophylaxis and the risk of surgical site infections results from the Trial to Reduce Antimicrobial

Prophylaxis Errors

Steinberg JP1 et al Ann Surg 2009

OBJECTIVE The objective of this study is to determine the optimal timing for surgical antimicrobial prophylaxis (AMP)

SUMMARY BACKGROUND DATA National AMP guidelines should be supported by evidence from large contemporary data sets

METHODS Twenty-nine hospitals prospectively obtained information on AMP from 4472 randomly selected cardiac hipknee

arthroplasty and hysterectomy cases Surgical site infections (SSIs) were ascertained through routine surveillance using National

Nosocomial Infections Surveillance system methodology The association between the prophylaxis timing and the occurrence of

SSI was assessed using conditional logistic regression (conditioning on hospital)

RESULTS One-hundred thirteen SSI were detected in 109 patients SSI risk increased incrementally as the interval of time

between antibiotic infusion and the incision increased (overall association between timing and infection risk P = 004) When

antibiotics requiring long infusion times (vancomycin and fluoroquinolones) were excluded the infection risk following

administration of antibiotic within 30 minutes prior to incision was 16 compared with 24 associated with administration of

antibiotic between 31 to 60 minutes prior to surgery (OR 174 95 confidence interval 098-304) The infection risk increased

as the time interval between preoperative antibiotic and incision increased or if the antibiotic was first infused after incision

(ORthinsp=thinsp220 95 CI 103-466) but not prior to 60 minutes Intraoperative redosing (performed in only 21 of long operations)

appeared to reduce SSI risk in operations lasting more than 4 hours (OR of 308 with no redosing 95 confidence interval 074-

1290) but only when the preoperative dose was given correctly

CONCLUSIONS These data from a large multicenter collaborative study confirm and extend previous observations and show a

consistent relationship between the timing of AMP and SSI risk with a trend toward lower risk occurring when AMP with

cephalosporins and other antibiotics with short infusion times were given within 30 minutes prior to incision

Impact of vancomycin surgical antibiotic prophylaxis on the development of methicillin-sensitive staphylococcus aureus surgical site infections report from Australian Surveillance Data (VICNISS) Bull AL1 Worth LJ Richards MJ Ann Surg 2012 OBJECTIVE To compare risks for developing surgical site infection (SSI) due to Staphylococcus aureus when vancomycin is used for antibiotic prophylaxis with risks when a β-lactam antibiotic is administered for prophylaxis BACKGROUND Vancomycin is often used as surgical antibiotic prophylaxis for major surgery In nonsurgical populations there is evidence that vancomycin is less effective for prevention and treatment of methicillin-sensitive Staphylococcus aureus (MSSA) infections Since 2002 the Victorian Healthcare Associated Surveillance System (VICNISS) has used standardized methods for infection surveillance in Australia including any prophylactic antibiotic agent administered before surgical procedures METHODS Surveillance records were obtained for patients undergoing 4 clean surgical procedures during the period of November 2002 to June 2009 Logistic regression analysis was used to examine risk factors for infection including age procedure duration American Society of Anesthesiologists score and choice and timing of antibiotic prophylaxis RESULTS The data set consisted of 22549 procedures including cardiac bypass and hip and knee arthroplasty procedures Vancomycin prophylaxis was administered in 1610 cases and a β-lactam antibiotic for 20939 cases A total of 754 SSIs were recorded The most frequent pathogens were MSSA methicillin-resistant Staphylococcus aureus and Pseudomonas species The adjusted odds ratio (OR) for an SSI with MSSA was 279 where vancomycin prophylaxis was administered (P lt 0001) For methicillin-resistant Staphylococcus aureus infection the adjusted OR for vancomycin was 044 (P = 005) whereas for Pseudomonas infection it was 096 (P = 095) CONCLUSIONS In a large Australian study population prophylaxis with vancomycin was found to be associated with an increased risk of SSI due to MSSA when compared with prophylaxis with a β-lactam antibiotic Given the potential for poorer surgical outcomes in the setting of indiscriminate prophylactic vancomycin use measures to improve adherence to guidelines for restricted administration of prophylactic vancomycin are supported

Impact of vancomycin surgical antibiotic prophylaxis on the development of methicillin-sensitive staphylococcus aureus surgical site infections report from Australian Surveillance Data (VICNISS) Bull AL1 Worth LJ Richards MJ Ann Surg 2012 OBJECTIVE To compare risks for developing surgical site infection (SSI) due to Staphylococcus aureus when vancomycin is used for antibiotic prophylaxis with risks when a β-lactam antibiotic is administered for prophylaxis BACKGROUND Vancomycin is often used as surgical antibiotic prophylaxis for major surgery In nonsurgical populations there is evidence that vancomycin is less effective for prevention and treatment of methicillin-sensitive Staphylococcus aureus (MSSA) infections Since 2002 the Victorian Healthcare Associated Surveillance System (VICNISS) has used standardized methods for infection surveillance in Australia including any prophylactic antibiotic agent administered before surgical procedures METHODS Surveillance records were obtained for patients undergoing 4 clean surgical procedures during the period of November 2002 to June 2009 Logistic regression analysis was used to examine risk factors for infection including age procedure duration American Society of Anesthesiologists score and choice and timing of antibiotic prophylaxis RESULTS The data set consisted of 22549 procedures including cardiac bypass and hip and knee arthroplasty procedures Vancomycin prophylaxis was administered in 1610 cases and a β-lactam antibiotic for 20939 cases A total of 754 SSIs were recorded The most frequent pathogens were MSSA methicillin-resistant Staphylococcus aureus and Pseudomonas species The adjusted odds ratio (OR) for an SSI with MSSA was 279 where vancomycin prophylaxis was administered (P lt 0001) For methicillin-resistant Staphylococcus aureus infection the adjusted OR for vancomycin was 044 (P = 005) whereas for Pseudomonas infection it was 096 (P = 095) CONCLUSIONS In a large Australian study population prophylaxis with vancomycin was found to be associated with an increased risk of SSI due to MSSA when compared with prophylaxis with a β-lactam antibiotic Given the potential for poorer surgical outcomes in the setting of indiscriminate prophylactic vancomycin use measures to improve adherence to guidelines for restricted administration of prophylactic vancomycin are supported

Quid du timing de lrsquoantibioprophylaxie

Timing of antimicrobial prophylaxis and the risk of surgical site infections results from the Trial to Reduce Antimicrobial

Prophylaxis Errors

Steinberg JP1 et al Ann Surg 2009

OBJECTIVE The objective of this study is to determine the optimal timing for surgical antimicrobial prophylaxis (AMP)

SUMMARY BACKGROUND DATA National AMP guidelines should be supported by evidence from large contemporary data sets

METHODS Twenty-nine hospitals prospectively obtained information on AMP from 4472 randomly selected cardiac hipknee

arthroplasty and hysterectomy cases Surgical site infections (SSIs) were ascertained through routine surveillance using National

Nosocomial Infections Surveillance system methodology The association between the prophylaxis timing and the occurrence of

SSI was assessed using conditional logistic regression (conditioning on hospital)

RESULTS One-hundred thirteen SSI were detected in 109 patients SSI risk increased incrementally as the interval of time

between antibiotic infusion and the incision increased (overall association between timing and infection risk P = 004) When

antibiotics requiring long infusion times (vancomycin and fluoroquinolones) were excluded the infection risk following

administration of antibiotic within 30 minutes prior to incision was 16 compared with 24 associated with administration of

antibiotic between 31 to 60 minutes prior to surgery (OR 174 95 confidence interval 098-304) The infection risk increased

as the time interval between preoperative antibiotic and incision increased or if the antibiotic was first infused after incision

(ORthinsp=thinsp220 95 CI 103-466) but not prior to 60 minutes Intraoperative redosing (performed in only 21 of long operations)

appeared to reduce SSI risk in operations lasting more than 4 hours (OR of 308 with no redosing 95 confidence interval 074-

1290) but only when the preoperative dose was given correctly

CONCLUSIONS These data from a large multicenter collaborative study confirm and extend previous observations and show a

consistent relationship between the timing of AMP and SSI risk with a trend toward lower risk occurring when AMP with

cephalosporins and other antibiotics with short infusion times were given within 30 minutes prior to incision

Timing of antimicrobial prophylaxis and the risk of surgical site infections results from the Trial to Reduce Antimicrobial

Prophylaxis Errors

Steinberg JP1 et al Ann Surg 2009

OBJECTIVE The objective of this study is to determine the optimal timing for surgical antimicrobial prophylaxis (AMP)

SUMMARY BACKGROUND DATA National AMP guidelines should be supported by evidence from large contemporary data sets

METHODS Twenty-nine hospitals prospectively obtained information on AMP from 4472 randomly selected cardiac hipknee

arthroplasty and hysterectomy cases Surgical site infections (SSIs) were ascertained through routine surveillance using National

Nosocomial Infections Surveillance system methodology The association between the prophylaxis timing and the occurrence of

SSI was assessed using conditional logistic regression (conditioning on hospital)

RESULTS One-hundred thirteen SSI were detected in 109 patients SSI risk increased incrementally as the interval of time

between antibiotic infusion and the incision increased (overall association between timing and infection risk P = 004) When

antibiotics requiring long infusion times (vancomycin and fluoroquinolones) were excluded the infection risk following

administration of antibiotic within 30 minutes prior to incision was 16 compared with 24 associated with administration of

antibiotic between 31 to 60 minutes prior to surgery (OR 174 95 confidence interval 098-304) The infection risk increased

as the time interval between preoperative antibiotic and incision increased or if the antibiotic was first infused after incision

(ORthinsp=thinsp220 95 CI 103-466) but not prior to 60 minutes Intraoperative redosing (performed in only 21 of long operations)

appeared to reduce SSI risk in operations lasting more than 4 hours (OR of 308 with no redosing 95 confidence interval 074-

1290) but only when the preoperative dose was given correctly

CONCLUSIONS These data from a large multicenter collaborative study confirm and extend previous observations and show a

consistent relationship between the timing of AMP and SSI risk with a trend toward lower risk occurring when AMP with

cephalosporins and other antibiotics with short infusion times were given within 30 minutes prior to incision

Impact of vancomycin surgical antibiotic prophylaxis on the development of methicillin-sensitive staphylococcus aureus surgical site infections report from Australian Surveillance Data (VICNISS) Bull AL1 Worth LJ Richards MJ Ann Surg 2012 OBJECTIVE To compare risks for developing surgical site infection (SSI) due to Staphylococcus aureus when vancomycin is used for antibiotic prophylaxis with risks when a β-lactam antibiotic is administered for prophylaxis BACKGROUND Vancomycin is often used as surgical antibiotic prophylaxis for major surgery In nonsurgical populations there is evidence that vancomycin is less effective for prevention and treatment of methicillin-sensitive Staphylococcus aureus (MSSA) infections Since 2002 the Victorian Healthcare Associated Surveillance System (VICNISS) has used standardized methods for infection surveillance in Australia including any prophylactic antibiotic agent administered before surgical procedures METHODS Surveillance records were obtained for patients undergoing 4 clean surgical procedures during the period of November 2002 to June 2009 Logistic regression analysis was used to examine risk factors for infection including age procedure duration American Society of Anesthesiologists score and choice and timing of antibiotic prophylaxis RESULTS The data set consisted of 22549 procedures including cardiac bypass and hip and knee arthroplasty procedures Vancomycin prophylaxis was administered in 1610 cases and a β-lactam antibiotic for 20939 cases A total of 754 SSIs were recorded The most frequent pathogens were MSSA methicillin-resistant Staphylococcus aureus and Pseudomonas species The adjusted odds ratio (OR) for an SSI with MSSA was 279 where vancomycin prophylaxis was administered (P lt 0001) For methicillin-resistant Staphylococcus aureus infection the adjusted OR for vancomycin was 044 (P = 005) whereas for Pseudomonas infection it was 096 (P = 095) CONCLUSIONS In a large Australian study population prophylaxis with vancomycin was found to be associated with an increased risk of SSI due to MSSA when compared with prophylaxis with a β-lactam antibiotic Given the potential for poorer surgical outcomes in the setting of indiscriminate prophylactic vancomycin use measures to improve adherence to guidelines for restricted administration of prophylactic vancomycin are supported
