The results of this study suggest that preoperative warming can reduce rates of SSI after surgery .
OBJECTIVE To determine whether preoperative warming can reduce the risk of surgical site infection ( SSI ) after surgery .
BACKGROUND Intraoperative hypothermia is a risk factor for the occurrence of  SSI in patients after surgery .
However , the effectiveness of preoperative warming in reducing the incidence of the condition remains unclear .
Multistate point-prevalence survey of health care-associated infections.
BACKGROUND Currently , no single U.S. surveillance system can provide estimates of the burden of all types of health care-associated infections across acute care patient population s. We conducted a prevalence survey in 10 geographically diverse states to determine the prevalence of health care-associated infections in acute care hospitals and generate up date d estimates of the national burden of such infections . METHODS We defined health care-associated infections with the use of National Healthcare Safety Network criteria .  One-day surveys of r and omly selected in patients were performed in participating hospitals . Hospital personnel collected demographic and limited clinical data . Trained data collectors review ed medical records retrospectively to identify health care-associated infections active at the time of the survey . Survey data and 2010 Nationwide Inpatient Sample data , stratified according to patient age and length of hospital stay , were used to estimate the total numbers of health care-associated infections and of in patients with such infections in U.S. acute care hospitals in 2011 . RESULTS Surveys were conducted in 183 hospitals . Of 11,282 patients , 452 had 1 or more health care-associated infections  ( 4.0 % ; 95 % confidence interval , 3.7 to 4.4 ) . Of 504 such infections , the most common types were pneumonia ( 21.8 % ) , surgical-site infections ( 21.8 % ) , and gastrointestinal infections ( 17.1 % ) . Clostridium difficile was the most commonly reported pathogen ( causing 12.1 % of health care-associated infections ) . Device-associated infections ( i.e. , central -catheter-associated bloodstream infection , catheter-associated urinary tract infection , and ventilator-associated pneumonia ) , which have traditionally been the focus of programs to prevent health care-associated infections , accounted for 25.6 % of such infections . We estimated that there were 648,000 patients with 721,800 health care-associated infections in U.S. acute care hospitals in 2011 . CONCLUSIONS Results of this multistate prevalence survey of health care-associated infections indicate that public health surveillance and prevention activities should continue to address C. difficile infections . As device- and procedure-associated infections decrease , consideration should be given to exp and ing surveillance and prevention activities to include other health care-associated infections
