J Hosp Infect 2024; 146:125-133. [PMID: 38295904 DOI: 10.1016/j.jhin.2024.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 01/11/2024] [Accepted: 01/13/2024] [Indexed: 03/10/2024]
Abstract
BACKGROUND Surveillance is an acknowledged method to decrease nosocomial infections, such as surgical site infections (SSIs). Electronic healthcare records create the opportunity for automated surveillance. While approaches for different types of surgeries and indicators already exist, there are very few for obstetrics and gynaecology. AIM To analyse the sensitivity and workload reduction of semi-automated surveillance in obstetrics and gynaecology. METHODS In this retrospective, single-centre study at a 1438-bed tertiary care hospital in Germany, semi-automated SSI surveillance using the indicators 'antibiotic prescription', 'microbiological data' and 'administrative data' (diagnosis codes, readmission, post-hospitalization care) was compared with manual analysis and categorization of all patient files. Breast surgeries (BSs) conducted in 2018 and caesarean sections (CSs) that met the inclusion criteria between May 2013 and December 2019 were included. Indicators were analysed for sensitivity, number of analysed procedures needed to identify one case, and potential workload reduction in detecting SSIs in comparison with the control group. FINDINGS The reference standard showed nine SSIs in 416 BSs (2.2%). Sensitivities for the indicators 'antibiotic prescription', 'diagnosis code', 'microbiological sample taken', and the combination 'diagnosis code or microbiological sample' were 100%, 88.9%, 66.7% and 100%, respectively. The reference standard showed 54 SSIs in 3438 CSs (1.6%). Sensitivities for the indicators 'collection of microbiological samples', 'diagnosis codes', 'readmission/post-hospitalization care', and the combination of all indicators were 38.9%, 27.8%, 85.2% and 94.4%, respectively. CONCLUSIONS Semi-automated surveillance systems may reduce workload by maintaining high sensitivity depending on the type of surgery, local circumstances and thorough digitalization.

Abstract
BACKGROUND The effect of hospital participation in the Japan Nosocomial Infection Surveillance (JANIS) programme on surgical site infection (SSI) prevention is unknown. AIM To determine if participation in the JANIS programme improved hospital performance in SSI prevention. METHODS This retrospective before-after study analysed Japanese acute care hospitals that joined the SSI component of the JANIS programme in 2013 or 2014. The study participants comprised patients who had undergone surgeries targeted for SSI surveillance at JANIS hospitals between 2012 and 2017. Exposure was defined as the receipt of an annual feedback report 1 year after participation in the JANIS programme. The changes in standardized infection ratio (SIR) from 1 year before to 3 years after exposure were calculated for 12 operative procedures: appendectomy, liver resection, cardiac surgery, cholecystectomy, colon surgery, caesarean section, spinal fusion, open reduction of long bone fracture, distal gastrectomy, total gastrectomy, rectal surgery, and small bowel surgery. Logistic regression models were used to analyse the association of each post-exposure year with the occurrence of SSI. FINDINGS In total, 157,343 surgeries at 319 hospitals were analysed. SIR values declined after participation in the JANIS programme for procedures such as liver resection and cardiac surgery. Participation in the JANIS programme was significantly associated with reduced SIR for several procedures, especially after 3 years. The odds ratios in the third post-exposure year (reference: pre-exposure year) were 0.86 [95% confidence interval (CI) 0.79-0.84] for colon surgery, 0.72 (95% CI 0.56-0.92) for distal gastrectomy, and 0.77 (95% CI 0.59-0.99) for total gastrectomy. CONCLUSION Participation in the JANIS programme was associated with improved SSI prevention performance in several procedures in Japanese hospitals after 3 years.

Risk Factors Associated with Surgical Site Infection following Cesarean Section in Tertiary Care Hospital, Nepal. Int J Reprod Med 2022; 2022:4442453. [PMID: 35615602 PMCID: PMC9126726 DOI: 10.1155/2022/4442453] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 04/08/2022] [Indexed: 11/17/2022] Open
Abstract
Background Cesarean section (CS) is one of the most performed surgeries in obstetrics. Surgical site infection is the major cause of morbidity and mortality causing an increase in the duration of hospitalization as well as the cost of admission for the patient. Objective To determine incidence of surgical site infection following cesarean section, classify them according to CDC criteria, and identify the different risk factors. Methodology. This is a case-control study conducted at the Department of Obstetrics and Gynecology at Tribhuvan University Teaching Hospital (TUTH), main campus of Institute of Medicine (IOM), Kathmandu, Nepal. Surgical site infections (SSI) in patients who underwent cesarean sections from February 2019 to August 2019 were taken as cases, while the patients who underwent cesarean section before or after the procedure and did not develop SSI comprised the controls. Visual inspection during ward rounds, reports from laboratory, and postprocedure follow-ups for up to 30 days formed the basis of identifying infections on the patients. Risk factors were identified by bivariate and multivariate logistic regression. Results Out of 1135 cases of cesarean sections, 97 of them developed SSI with incidence rate of 8.54%. Among them, 94.85% were superficial incisional and 5.15% were deep incisional type of SSI with no organ space type. Cases had higher mean age 26.88 ± 4.38 years compared to 24.81 ± 5.08 years in controls. Host-related risk factors which led to higher odds of developing surgical site infection (SSI) were obesity with adjusted odds ratio (AOR) 15.72 (confidence interval (CI): 4.60-53.67), diabetes/hypertension in pregnancy with AOR 4.75(CI 1.69-13.32), and other medical diseases with AOR 9.38 (CI 2.89-30.46). Duration of the rupture of membrane for more than 18 hours with AOR 8.38 (CI 1.48-47.35), more than five per vaginal (PV) examination with AOR 1.93 (95% CI 1.03-3.64), and in labor status with AOR 6.52 (CI 1.17-36.38) were some procedure-related factors resulting into higher odds of infection. Conclusion Multiple risk factors like age, obesity, medical complications during pregnancy, occurrence of labor status during cesarean section, prolonged duration of rupture of membrane for more than 18 hours, and more than five vaginal examinations before the procedure increases the chance of surgical site infection (SSI) following cesarean section.

Abstract
OBJECTIVE Surgical site infection (SSI) prevention remains significant, particularly in the era of antimicrobial resistance. Feedback on practices and outcomes is known to be key to reduce SSI rates and optimize antibiotic usage. However, the optimal method, format and frequency of feedback for surgical teams remains unclear. The objective of the study is to understand how data from surveillance and audit are fed back in routine surgical practice. METHODS A systematic scoping review was conducted, using well-established implementation science frameworks to code the data. Two electronic health-oriented databases (MEDLINE, EMBASE) were searched to September 2019. We included studies that assessed the use of feedback as a strategy either in the prevention and management of SSI and/or in the use of antibiotics perioperatively. RESULTS We identified 21 studies: 17 focused on SSI rates and outcomes and 10 studies described antimicrobial stewardship for SSI (with some overlap in focus). Several interventions were reported, mostly multimodal with feedback as a component. Feedback was often provided in written format (62%), either individualized (38%) or in group (48%). Only 25% of the studies reported that feedback cascaded down to the frontline perioperative staff. In 65% of the studies, 1 to 5 implementation strategies were used while only 5% of the studies reported to have utilized more than 15 implementation strategies. Among studies reporting antibiotic usage in surgery, most (71%) discussed compliance with surgical antibiotic prophylaxis. CONCLUSIONS Our findings highlight the need to provide feedback to all levels of perioperative care providers involved in patient care. Future research in this area should report implementation parameters in more detail.

Abstract
OBJECTIVE To estimate the economic burden to the health service of surgical site infection following caesarean section and to identify potential savings achievable through implementation of a surveillance programme. DESIGN Economic model to evaluate the costs and benefits of surveillance from community and hospital healthcare providers' perspective. SETTING England. PARTICIPANTS Women undergoing caesarean section in National Health Service hospitals. MAIN OUTCOME MEASURE Costs attributable to treatment and management of surgical site infection following caesarean section. RESULTS The costs (2010) for a hospital carrying out 800 caesarean sections a year based on infection risk of 9.6% were estimated at £18 914 (95% CI 11 521 to 29 499) with 28% accounted for by community care (£5370). With inflation to 2019 prices, this equates to an estimated cost of £5.0 m for all caesarean sections performed annually in England 2018-2019, approximately £1866 and £93 per infection managed in hospital and community, respectively. The cost of surveillance for a hospital for one calendar quarter was estimated as £3747 (2010 costs). Modelling a decrease in risk of infection of 30%, 20% or 10% between successive surveillance periods indicated that a variable intermittent surveillance strategy achieved higher or similar net savings than continuous surveillance. Breakeven was reached sooner with the variable surveillance strategy than continuous surveillance when the baseline risk of infection was 10% or 15% and smaller loses with a baseline risk of 5%. CONCLUSION Surveillance of surgical site infections after caesarean section with feedback of data to surgical teams offers a potentially effective means to reduce infection risk, improve patient experience and save money for the health service.

Implementation of a comprehensive unit-based safety program to reduce surgical site infections in cesarean delivery. Am J Infect Control 2020; 48:386-390. [PMID: 32093979 DOI: 10.1016/j.ajic.2020.01.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 01/12/2020] [Accepted: 01/18/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND To evaluate whether using a comprehensive and multidisciplinary approach to implement an evidence-based bundle can reduce 30-day surgical site infection rates in women undergoing cesarean delivery. METHODS This observational study with a preintervention and postintervention design included 2576 consecutive women undergoing cesarean delivery at our tertiary care hospital between January 1, 2013 and December 31, 2017. The primary outcome was 30-day surgical site infection rate after cesarean delivery defined according to the Centers for Disease Control and Prevention criteria. The preintervention period span from the January 1, 2013 to December 31, 2014. After initiation of a Comprehensive Unit-based Safety Program (ie, a continuous quality improvement program to improve patient safety using a comprehensive and multidisciplinary approach adapted on local demands), we introduced a bundle of evidence-based interventions (including preoperative shower, hair removal with clippers, correct antibiotic prophylaxis, maintaining normothermia, glycemic control, and strict compliance with hygiene standards as well as practice good hand hygiene) per January 1, 2015 into clinical routine. The postintervention period span from January 1, 2015 to December 31 2017. RESULTS In the preintervention period the overall surgical site infection rate was 16 of 1,060 cesarean deliveries versus in the postintervention period the overall surgical site infection rate was 9 of 1,516 cesarean deliveries (1.50% vs 0.56%; P = .033). This corresponds to a relative risk reduction of over 60% after implementation of the evidence-based bundle (odds ratio 0.39, 95% confidence interval 0.17-0.89; P = .020). CONCLUSIONS In the present study, we have adapted the Comprehensive Unit-based Safety Program strategy to implement an evidence based-bundle into clinical routine. Using this comprehensive and multidisciplinary approach, we could markedly reduce 30-day surgical site infections.

Abstract
OBJECTIVE To determine the rate and associated risk factors for incisional surgical site infection following cesarean section in Ireland. STUDY DESIGN This study was a retrospective population-based cohort study, conducted using the Hospital In-Patient Enquiry database (HIPE) for the period 2005-2016. All women who underwent cesarean section between 2005 and 2016 in Ireland were included. Potential risk factors for incisional surgical site infection were selected based on the existing literature and their availability within the HIPE database. The risk of incisional surgical site infection following cesarean section with exact Poisson 95% confidence intervals were reported. Multivariable Poisson regression included all potential risk factors simultaneously. Risk ratios are reported with their 95% confidence intervals and P-values. RESULTS There were 802,182 deliveries during the study period, 219,859 of which (27.4%) were by cesarean section. There were 1396 cases of incisional surgical site infection, a risk of 0.63% (95% confidence interval: 0.60-0.67%). Public patients had approximately 20% higher risk and the risk was almost 40% higher among women aged over 35 years compared with those aged under 25 years. Most notable, related to the morbidities assessed, was the twofold increased risk of incisional surgical site infection associated with pre-existing diabetes and with urinary tract infection in pregnancy. Premature rupture of membranes, pyrexia during labour and postpartum haemorrhage each increased risk by 40-60%. Hematoma of a cesarean section wound remained by far the strongest risk factor for incisional surgical site infection. CONCLUSION Of all the risk factors we studied, hematoma had the strongest association with development of incisional surgical site infection. Of all women birthing by cesarean section in Ireland during 2005-2016, 25% had at least one of the risk factors identified by our study. Approximately 40% of the incisional surgical site infection cases came from this 25%. This might suggest that a universal approach to reducing risk of surgical site infection is warranted.

Abstract
BACKGROUND According to previously studies, nosocomial infections (NIs) surveillance could effectively reduce infection rates. As NIs surveillance systems have been implemented in some hospitals for several years, their impact on NIs need to be explored. Therefore, the purpose of this review is to evaluate the tendency of NI rates during the surveillance period and the impact of surveillance on NI rates. METHODS A systematic literature search of the PubMed database to identify papers that evaluated effect of surveillance on NIs, all kinds of NIs occurred during hospitalization or discharged were included. Exclude articles investigated the surveillance combined with other infection control measures. RESULTS Twenty-five articles were included. NI rates had different levels of reduction during surveillance period, the reduction were not limited by state, department, surveillance system, and NI type. Continuous surveillance had a positive impact on NI, OR/RR were ranged from 0.43 to 0.95. CONCLUSION Participation in NI surveillance is associated with reducing infection rates, though RCTs need to further prove the effective role of surveillance. Hospitals may consider to perform NIs surveillance systems according to its own conditions.

Abstract
Health care-associated infections (HAI) are a major public health problem with a significant impact on morbidity, mortality and quality of life. They represent also an important economic burden to health systems worldwide. However, a large proportion of HAI are preventable through effective infection prevention and control (IPC) measures. Improvements in IPC at the national and facility level are critical for the successful containment of antimicrobial resistance and the prevention of HAI, including outbreaks of highly transmissible diseases through high quality care within the context of universal health coverage. Given the limited availability of IPC evidence-based guidance and standards, the World Health Organization (WHO) decided to prioritize the development of global recommendations on the core components of effective IPC programmes both at the national and acute health care facility level, based on systematic literature reviews and expert consensus. The aim of the guideline development process was to identify the evidence and evaluate its quality, consider patient values and preferences, resource implications, and the feasibility and acceptability of the recommendations. As a result, 11 recommendations and three good practice statements are presented here, including a summary of the supporting evidence, and form the substance of a new WHO IPC guideline.

Background This study aimed to investigate the prevalence of healthcare-associated infection (HAI) in the China-Japan Friendship Hospital, a tertiary level hospital in Beijing, China. Methods We defined HAI using the criteria established by the Ministry of Health of the People’s Republic of China. Three cross-sectional surveys were conducted from 2012 to 2014. Inpatients who had been hospitalized for at least 48 h were surveyed. Information on HAI prevalence, isolated pathogens and use of antibiotics were collected. Logistic regression models were used to assess the associations between HAI and potential risk factors. Results During three cross-sectional surveys, a total number of 4,029 patients were included (1,233 patients in 2012, 1,220 patients in 2013 and 1,576 patients in 2014). The overall prevalence of patients with HAI was 3.6 % (95 % confidence interval (CI) 3.1 %–4.2 %). Respiratory tract infections were the most common type (64.7 %) of HAIs, followed by urinary tract infections (12.6 %) and bloodstream infections (5.4 %). HAI occurrences were significantly associated with male sex (odds ratio (OR) = 2.25, 95 % CI 1.53-3.32), age over 85 years (OR = 4.74, 95 % CI 2.54–8.83), hospitalization in the intensive care units (ICUs) (OR = 2.42, 95 % CI 1.31–4.49), indwelling urinary catheter (OR = 4.21, 95 % CI 2.46–7.20) and mechanical ventilation (OR = 2.31, 95 % CI 1.30–4.09). Gram-negative bacteria were found to be the most isolated pathogens (67.1 %), with gram-positive bacteria and fungi accounted for 20.3 % and 10.5 %, respectively. Antibiotics were administered to 34.3 % of the included patients over the study period. Conclusions The overall HAI prevalence in our hospital is similar to previous studies that were conducted in other areas of China, and the respiratory tract infection should be the priority in HAI reduction control within China. We should focus HAI reduction efforts on patients with advanced age, hospitalization in the ICU and indwelling devices.

Abstract
OBJECTIVE To describe the epidemiology of healthcare-associated infections (HAI) in hospitals participating in the German national nosocomial infections surveillance system (KISS). METHOD The epidemiology of HAI was described for the surveillance components for intensive care units (ITS-KISS), non-ICUs (STATIONS-KISS), very low birth weight infants (NEO-KISS) and surgical site infections (OP-KISS) in the period from 2006 to 2013. In addition, risk factor analyses were performed for the most important infections of ICU-KISS, NEO-KISS and OP-KISS. RESULTS Data from a total of 3,454,778 ICU patients from 913 ICUs, 618,816 non-ICU patients from 142 non-ICU wards, 53,676 VLBW from 241 neonatal intensive care units (NICU) and 1,005,064 surgical patients from operative departments from 550 hospitals were used for analysis. Compared with baseline data, a significant reduction of primary bloodstream infections (PBSI) and lower respiratory tract infections (LRTI) was observed in ICUs with the maximum effect in year 5 (or longer participation) (incidence rate ratio 0.60 (CI95 0.50-0.72) and 0.61 (CI95 0.52-0.71) respectively). A significant reduction of PBSI and LRTI was also observed in NEO-KISS when comparing the baseline situation with the 5th year of participation (hazard ratio 0.70 (CI95 0.64-0.76) and 0.43 (CI95 0.35-0.52)). The effect was smaller in operative departments after the introduction of OP-KISS (OR 0.80; CI95 0.64-1.02 in year 5 or later for all procedure types combined). Due to the large database, it has not only been possible to confirm well-known risk factors for HAI, but also to identify some new interesting risk factors like seasonal and volume effects. CONCLUSIONS Participating in a national surveillance system and using surveillance data for internal quality management leads to substantial reduction of HAI. In addition, a surveillance system can identify otherwise not recognized risk factors which should - if possible - be considered for infection control management and for risk adjustment in the benchmarking process.

Abstract
Objective.To evaluate the time trend in the surgical site infection (SSI) rate in relation to the duration of surveillance in The Netherlands.Setting.Forty-two hospitals that participated in the the Dutch national nosocomial surveillance network, which is known as PREZIES (Preventie van Ziekenhuisinfecties door Surveillance), and that registered at least 1 of the following 5 frequently performed surgical procedures for at least 3 years during the period from 1996 through 2006: mastectomy, colectomy, replacement of the head of the femur, total hip arthroplasty, or knee arthroplasty.Methods.Analyses were performed for each surgical procedure. The surveillance time to operation was stratified in consecutive 1-year periods, with the first year as reference. Multivariate logistic regression analysis was performed using a random coefficient model to adjust for random variation among hospitals. All models were adjusted for method of postdischarge surveillance.Results.The number of procedures varied from 3,031 for colectomy to 31,407 for total hip arthroplasty, and the SSI rate varied from 1.6% for knee arthroplasty to 12.2% for colectomy. For total hip arthroplasty, the SSI rate decreased significantly by 6% per year of surveillance (odds ratio [OR], 0.94 [95% confidence interval {CI}, 0.90–0.98]), indicating a 60% decrease after 10 years. Nonsignificant but substantial decreasing trends in the rate of SSI were found for replacement of the head of the femur (OR, 0.94 [95% CI, 0.88–1.00]) and for colectomy (OR, 0.92 [95% CI, 0.83–1.02]).Conclusions.Even though most decreasing trends in the SSI rate were not statistically significant, they were encouraging. To use limited resources as efficiently as possible, we would suggest switching the surveillance to another surgical procedure when the SSI rate for that particular procedure has decreased below the target rate.

Abstract
Objective.To evaluate whether the adjusted rates of surgical site infection (SSI) and urinary tract infection (UTI) after cesarean delivery decrease in maternity units that perform active healthcare-associated infection surveillance.Design.Trend analysis by means of multiple logistic regression.Setting.A total of 80 maternity units participating in the Mater Sud-Est surveillance network.Patients.A total of 37,074 cesarean deliveries were included in the surveillance from January 1, 1997, through December 31, 2003.Methods.We used a logistic regression model to estimate risk-adjusted post–cesarean delivery infection odds ratios. The variables included were the maternity units' annual rate of operative procedures, the level of dispensed neonatal care, the year of delivery, maternal risk factors, and the characteristics of cesarean delivery. The trend of risk-adjusted odds ratios for SSI and UTI during the study period was studied by linear regression.Results.The crude rates of SSI and UTI after cesarean delivery were 1.5% (571 of 37,074 patients) and 1.8% (685 of 37,074 patients), respectively. During the study period, the decrease in SSI and UTI adjusted odds ratios was statistically significant (R = −0.823 [P = .023] and R = −0.906 [P = .005], respectively).Conclusion.Reductions of 48% in the SSI rate and 52% in the UTI rate were observed in the maternity units. These unbiased trends could be related to progress in preventive practices as a result of the increased dissemination of national standards and a collaborative surveillance with benchmarking of rates.

Abstract
BACKGROUND Given the continued rise in cesarean birth rate and the increased risk of surgical site infections after cesarean birth compared with vaginal birth, effective interventions must be established for prevention of surgical site infections. Prophylactic intravenous (IV) antibiotic administration 60 minutes prior to skin incision is recommended for abdominal gynecologic surgery; however, administration of prophylactic antibiotics has traditionally been withheld until after neonatal umbilical cord clamping during cesarean delivery due to the concern for potential transfer of antibiotics to the neonate. OBJECTIVES To compare the effects of cesarean antibiotic prophylaxis administered preoperatively versus after neonatal cord clamp on postoperative infectious complications for both the mother and the neonate. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 March 2014) and reference lists of retrieved papers. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing maternal and neonatal outcomes following prophylactic antibiotics administered prior to skin incision versus after neonatal cord clamping during cesarean delivery. Cluster-RCTs were eligible for inclusion but none were identified. Quasi-RCT and trials using a cross-over design were not eligible for inclusion in this review. Studies published in abstract form only were eligible for inclusion if sufficient information was available in the report. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed the studies for inclusion, assessed risk of bias, abstracted data and checked entries for accuracy. We assessed the quality of evidence using the GRADE approach. MAIN RESULTS We included 10 studies (12 trial reports) from which 5041 women contributed data for the primary outcome. The overall risk of bias was low.When comparing prophylactic intravenous (IV) antibiotic administration in women undergoing cesarean delivery, there was a reduction in composite maternal infectious morbidity (risk ratio (RR) 0.57, 95% confidence interval (CI) 0.45 to 0.72, high quality evidence), which was specifically due to the reduction in endometritis (RR 0.54, 95% CI 0.36 to 0.79, high quality evidence) and wound infection (RR 0.59, 95% CI 0.44 to 0.81, high quality evidence) in those that received antibiotics preoperatively as compared to those who received antibiotics after neonatal cord clamping. There were no clear differences in neonatal sepsis (RR 0.76, 95% CI 0.51 to 1.13, moderate quality evidence).There were no clear differences for other maternal outcomes such as urinary tract infection (UTI), cystitis and pyelonephritis (moderate quality evidence), respiratory infection (low quality evidence), or any neonatal outcomes. Maternal side effects were not reported in the included studies.The quality of the evidence using GRADE was high for composite morbidity, endomyometritis, wound infection and neonatal intensive care unit admission, moderate for UTI/cystitis/pyelonephritis and neonatal sepsis, and low for maternal respiratory infection. AUTHORS' CONCLUSIONS Based on high quality evidence from studies whose overall risk of bias is low, intravenous prophylactic antibiotics for cesarean administered preoperatively significantly decreases the incidence of composite maternal postpartum infectious morbidity as compared with administration after cord clamp. There were no clear differences in adverse neonatal outcomes reported. Women undergoing cesarean delivery should receive antibiotic prophylaxis preoperatively to reduce maternal infectious morbidities. Further research may be needed to elucidate short- and long-term adverse effects for neonates.

Abstract
OBJECTIVE To determine the spectrum of etiology and the incidence of healthcare-associated infections (HAIs) among gynecologic and obstetric patients. METHODS In a descriptive survey, data were analyzed from in-patients at the Department of Gynecology and Obstetrics, University Hospital and Faculty of Medicine in Hradec Králové, Czech Republic, between January 2007 and December 2011. RESULTS Among 21 937 patients treated during the study period, there were 189 (0.86%) cases of HAI. Gynecologic patients had a higher incidence of HAIs (1.31%) compared with pregnant women (0.60%). The incidence of HAI was 0.13% after laparoscopic surgery, 0.63% after a minor gynecologic intervention, and 3.73% after major surgery. Vaginal delivery (0.36%) represented a low risk of HAI. Compared with vaginal delivery, the incidence of HAI increased twofold for planned cesarean delivery (0.64%), and tenfold for emergency cesarean delivery (3.63%). The majority of causative microorganisms (72.7%) were susceptible to penicillin antibiotics. None of the patients died as a result of HAI. CONCLUSION The incidence of HAIs at a university hospital in the Czech Republic was very low. Antibiotic resistance was only a minor problem, and the incidence of multiresistant strains was rare.

Abstract
BACKGROUND Surgical site infection (SSI) is an important complication of cesarean section (CS) delivery and a key quality indicator of patient care. METHODS A baseline assessment was undertaken to determine SSI rates, and subsequently a quality improvement program was introduced, followed by repeat surveillance. Data were collected during in-hospital stays and for up to 30 days after CS during both periods. Interventions in the quality improvement program included the use of nonabsorbable sutures for skin closure, use of clippers instead of razors, and use of 2% ChloraPrep for skin disinfection before incision. RESULTS A total of 710 patients were surveyed before the interventions, and 824 patients were surveyed after the interventions. Of these, 114 (16%) had an SSI before the interventions, and 40 (4.9%) had an SSI after the interventions (P < .001; odds ratio, 0.27), with 90% and 83%, respectively, detected after hospital discharge. In multivariate analysis, obesity (P = .002) and the use of absorbable suture materials for skin closure (P = .008) were significantly associated with a higher SSI rate before the interventions; however, only obesity was associated with a higher SSI rate after the quality program. CONCLUSION Surveillance of SSI rates after CS followed by 3 interventions contributed to a significant reduction in SSI rate and improved patient care.

Abstract
Background Surgical site infections (SSIs) are difficult to treat and are associated with substantially longer hospital stay, higher treatment cost, morbidity and mortality, particularly when the etiological agent is multidrug-resistant (MDR). To address the limited data in Uganda on SSIs, we present the spectrum of bacteria isolated from hospitalized patients, the magnitude and impact of MDR bacterial isolates among patients with SSIs. Methods A descriptive cross sectional study was conducted from September 2011 through April 2012 involving 314 patients with SSIs in the obstetrics & gynecology, general surgery and orthopedic wards at Mulago National Hospital in Kampala, Uganda. Wound swabs were taken and processed using standard microbiological methods. Clinico-demographic characteristics of patients were obtained using structured questionnaires and patients’ files. Results Of the 314 enrolled patients with SSIs (mean age 29.7 ±13.14 years), 239 (76.1%) were female. More than half of the patients were from obstetrics and gynecology (62.1%, 195/314). Of 314 wound swabs taken, 68.8% (216/314) were culture positive aerobically, yielding 304 bacterial isolates; of which 23.7% (72/304) were Escherichia coli and 21.1% (64/304) were Staphylococcus aureus. More than three quarters of Enterobacteriaceae were found to be extended spectrum beta lactamase (ESBL) producers and 37.5% of S. aureus were Methicillin resistant S. aureus (MRSA). MDR occurred in 78.3% (238/304) of the isolates; these were more among Gram-negative bacteria (78.6%, 187/238) compared to Gram-positive bacteria (21.4%, 51/238), (p-value < 0.0001, χ2 = 49.219). Amikacin and imepenem for ESBL-producing Enterobacteriacea and vancomycin for MRSA showed excellent performance except that they remain expensive drugs in Uganda. Conclusion Most SSIs at Mulago National Hospital are due to MDR bacteria. Isolation of MRSA and ESBL-producing Enterobacteriaceae in higher proportions than previously reported calls for laboratory guided SSIs- therapy and strengthening of infection control surveillance in this setting.

Abstract
Successive point-prevalence surveys were conducted annually from 2007 to 2011 to monitor the prevalence of healthcare-associated infections (HAIs) in a university hospital in Hubei Province in China. The surveys used the case definition criteria established by the Ministry of Health of the People's Republic of China. In the 5 surveys, the overall frequency of HAIs was 3.16% (301/9533). No significant differences were identified in the point prevalence measurements of HAIs in any of the years from 2007 to 2011. Of all the cases, proportionally, the most frequent infection site was the respiratory tract (2.34%), followed by surgical sites (0.43%) and urinary tract sites (0.28%). Gram-negative aerobic bacilli were the most common organisms mentioned; the most frequently isolated organism was Pseudomonas aeruginosa, followed by Escherichia coli and Acinetobacter baumannii. Approximately one-half of the patients were receiving antibiotics at the time of the surveys. Cephalosporin, penicillin, and quinolone were most commonly used for treatment or prevention. The differences found in HAI prevalence data across the 5 surveys given in the hospital were not statistically significant. In conclusion, this successive point-prevalence survey provides information about the trend of HAI prevalence, epidemical character, and the use of antibiotics among the university hospital's in-patients. This information allows us to initiate targeted programs for infection prevention and control.

Abstract
BACKGROUND Short postoperative stays following caesarean section delivery make it difficult to assess accurately the risk of surgical site infection (SSI). Methods of case-finding that minimize variation are required to support effective surveillance systems, especially where used for benchmarking. AIM To evaluate the efficacy of case-finding methods for SSI following caesarean delivery and their utility in establishing benchmark rates of SSI. METHODS Hospitals conducted surveillance over one or two 13-week periods. Patients were reviewed during their inpatient stay, post partum by community midwives and via patient questionnaire at 30 days post delivery. To estimate the reliability of case-finding methods, case-note reviews were undertaken in a random sample of four hospitals. FINDINGS A total of 404 SSIs were detected in 4107 caesarean deliveries from 14 hospitals. The median time to SSI was 10 days, 66% were detected in-hospital or by community midwives, and an additional 34% were patient-reported. The rate of SSI was 9.8% but the proportion of patients followed up varied significantly between centres. The estimated sensitivity and specificity of case-finding was 91.4% [95% confidence interval (CI): 53.4-98.4] and 98.6% (95% CI: 98.4-98.8), the positive predictive value 91.0% (95% CI: 82.4-96.1) and negative predictive value 98.6% (95% CI: 93.9-99.5). CONCLUSIONS Combined case ascertainment methods are a feasible way to achieve active post-discharge surveillance and had high negative and positive predictive values. Additional SSIs can be detected by patient questionnaires but rates of SSI were strongly influenced by variation in intensity of both healthcare worker- and patient-based case-finding. This factor must be taken into account when comparing or benchmarking rates of SSI.

The vast majority of pregnancies occur amongst a generally healthy patient population, i.e. females from the teenage years in to the 40s. In most cases, the pregnancy is uneventful and where infections do arise, these are often relatively minor and easily treatable, e.g. urinary tract infection and vaginal thrush. However, sepsis is now the leading cause of maternal deaths in the UK accounting for 26 deaths between 2006 and 2008 and there has been an increase in death due to community-acquired Group A streptococcal (GAS) (also known as Streptococcus pyogenes) disease [1]. A literature review of 55 pregnancies with symptomatic Groups A streptococcal infection since 1966 recorded early onset septic shock in 91 % with a maternal mortality rate of 58 % but the mortality has improved to 32 % in recent years [2]. Furthermore, when toxic shock syndrome due to Group A streptococci (can also be caused by Staphylococcus aureus) occurs during pregnant, it can have devasting consequences with multi-organ failure and a mortality of over 50 % in reported cases [3]. A recent review from the UK covers many of the important issues associated with GAS in the obstetrical setting including the its diverse manifestations, the need to manage puerperal sepsis caused by GAS quickly, suggested initial antibiotic therapy (e.g. cefuroxime and metronidazole until confirmed), and issues such as prophylaxis for contacts and the possible role of intravenous immunoglobulins [4].

Abstract
BACKGROUND We implemented evidence-based interventions to reduce risk of surgical site infection (SSI) following low transverse cesarean section (LTCS). METHODS An observational study was conducted to determine LTCS SSI rates and the impact of infection control interventions at an academic teaching hospital during the period October 2005 to December 2008, including the use of 2% chlorhexidine gluconate (CHG) for surgical skin preparation before LTCS and no-rinse CHG cloths for preoperative skin cleansing. We compared overall and risk strata specific SSI rates and standardized incidence ratios during 4 study periods and estimated cost savings. RESULTS Of 1,844 LTCSs performed, 99 patients were identified with SSI. SSI rates per 100 LTCS declined from 6.27 at baseline and 10.84 during the outbreak period to 5.92 in intervention 1 period and 2.29 in intervention 2 period. Overall, a 63.5% reduction in SSI rate from baseline was achieved by ensuring compliance with SSI prevention guidelines and improving skin antisepsis (P = .003). In intervention 2 period, the standardized incidence ratio was 0.99 compared with 2.64 at baseline and 4.50 during the outbreak period. CONCLUSION A multidisciplinary approach including evidence-based SSI prevention practices, effective infection prevention products, and staff and patient engagement substantially reduced infection risk and improved patient safety following LTCS.

Abstract
OBJECTIVE To evaluate different strategies for detecting surgical site infections (SSIs) using different sources (notification by the surgeon, bacteriological results, antibiotic prescription, and discharge diagnosis codes). BACKGROUND Surveillance plays a role in reducing the risks of SSIs but the performance of case reports by surgeons is insufficient. Indirect methods of SSI detection are an alternative to increase the quality of surveillance. METHODS A retrospective cohort study of 446 patients operated consecutively during the first half of 2007 was set up in a 56-bed general surgery unit in Lyon University Hospital, France. Patients were followed up 30 days after intervention. Different methods of detection were established by combining different data sources. The sensitivity and specificity of these methods were calculated by using, as reference method, the manual review of the medical records. RESULTS The sensitivity and specificity of SSI detection were, respectively, 18.4% (95% confidence interval [CI]: 7.9-31.6) and 100% for surgeon notification; 63.2% (95% CI: 47.3-78.9) and 95.1% (95% CI: 92.9-97.1) for detection based on positive cultures; 68.4% (95% CI: 52.6-81.6) and 87.5% (95% CI: 84.3-90.7) using antibiotic prescription; 26.3% (95% CI: 13.2-42.1) and 99.5% (95% CI: 98.8-100) using discharge diagnosis codes. By combining the latter 3 sources, the sensitivity increased at 86.8% (95% CI: 76.3-97.4) and the specificity was lowered at 85.5% (95% CI: 82.1-89.0). CONCLUSIONS SSI detection based on the combination of data extracted automatically from the hospital information system performed well. This strategy has been implemented gradually in Lyon University Hospital.

Abstract
Healthcare acquired (nosocomial) infections are one of the most frequent complications of medical care. The management to prevent such nosocomial infections is a typical example of the use of the general principles of quality management in healthcare institutions: each institution should compare their own nosocomial infection rates for defined patient risk groups with reference data and identify problems concerning specific infection types or units/departments. This comparison should stimulate a careful analysis of the process of care and the options to improve the situation. Structured interventions, such as the introduction of bundles of infection control measures or checklists, are very helpful to increase compliance with infection control measures and to decrease nosocomial infection rates. However, often only interventions individually designed according to the specific needs in a particular unit/department are successful to improve infection rates. Therefore, the employment of experienced infection control personnel and surveillance strategies designed according to the specific needs of the institution are key elements of a good infection control management within healthcare institutions.

Abstract
PURPOSES Unfortunately, surgical site infections (SSIs) are a quite common complication and represent one of the major causes of postoperative morbidity and mortality, and may furthermore lead to enormous additional costs for hospitals and health care systems. METHODS In order to determine the estimated costs due to SSIs, a MEDLINE search was performed to identify articles that provide data on economic aspects of SSIs and compared to findings from a matched case-control study on costs of SSIs after coronary bypass grafting (CABG) in a German tertiary care university hospital. RESULTS A total of 14 studies on costs were found. The additional costs of SSI vary between $3,859 (mean) and $40,559 (median). Median costs of a single CABG case in the recently published study were $49,449 (€36,261) vs. $18,218 (€13,356) in controls lacking infection (p < 0.0001). The median reimbursement from health care insurance companies was $36,962 (€27,107) leading to a financial loss of $12,482 (€9,154) each. CONCLUSION Costs of SSIs may almost triple the individual overall health care costs and those additional charges may not be sufficiently covered. Appropriate measures to reduce SSI rates must be taken to improve the patient's safety. This should also diminish costs for health care systems which benefits the entire community.

Abstract
The epidemiology of MRSA pneumonia varies across countries. One of the most import risk factors for the development of nosocomial MRSA pneumonia is mechanical ventilation. Methicillin resistance in S. aureus ventilator associated pneumonia (VAP) ranged between 37% in German, 54% in the US American and 78% in Asian and Latin American ICUs. In 2009, the incidence density of nosocomial VAP caused by MRSA was 0.28 per 1000 ventilation days in a network of 586 German ICUs. Incidences peaked in neurological and neurosurgical ICUs. Crude hospital mortality in studies performed after 2005 lay between 27% and 59% and attributable MRSA pneumonia mortality at 40%. Since 2005, US American and German data indicate decreasing trends for MRSA pneumonia. Measures to reduce MRSA pneumonia or to control the spread of MRSA include hand hygiene, standard and contact precautions, oral contamination with chlor hexidine, skin decontamination with antiseptics, screening, and (possibly) patient isolation in a single room.

Abstract
Caesarean delivery is frequently complicated by surgical site infections, endometritis and urinary tract infection. Most surgical site infections occur after discharge from the hospital, and are increasingly being used as performance indicators. Worldwide, the rate of caesarean delivery is increasing. Evidence-based guidelines recommended the use of prophylactic antibiotics before surgical incision. An exception is made for caesarean delivery, where narrow-range antibiotics are administered after umbilical cord clamping because of putative neonatal benefit. However, recent evidence supports the use of pre-incision, broad-spectrum antibiotics, which result in a lower rate of maternal morbidity with no disadvantage to the neonate.

Abstract
BACKGROUND Ambiguity remains about the effectiveness of wearing surgical face masks. The purpose of this study was to assess the impact on surgical site infections (SSIs) when non-scrubbed operating room staff did not wear surgical face masks. METHODS Eight hundred twenty-seven participants undergoing elective or emergency obstetric, gynecological, general, orthopaedic, breast or urological surgery in an Australian tertiary hospital were enrolled. Complete follow-up data were available for 811 patients (98.1%). Operating room lists were randomly allocated to a 'Mask group' (all non-scrubbed staff wore a mask) or 'No Mask group' (none of the non-scrubbed staff wore masks). The primary end point, SSI was identified using in-patient surveillance; post discharge follow-up and chart reviews. The patient was followed for up to six weeks. RESULTS Overall, 83 (10.2%) surgical site infections were recorded; 46/401 (11.5%) in the Masked group and 37/410 (9.0%) in the No Mask group; odds ratio (OR) 0.77 (95% confidence interval (CI) 0.49 to 1.21), p = 0.151. Independent risk factors for surgical site infection included: any pre-operative stay (adjusted odds ratio [aOR], 0.43 (95% CI, 0.20; 0.95), high BMI aOR, 0.38 (95% CI, 0.17; 0.87), and any previous surgical site infection aOR, 0.40 (95% CI, 0.17; 0.89). CONCLUSION Surgical site infection rates did not increase when non-scrubbed operating room personnel did not wear a face mask.

Abstract
Abstract
Background
The aim of this cluster-randomized, crossover trial was to compare the efficacy of plain soap and water with an alcohol-based handrub for surgical hand preparation and prevention of surgical-site infection (SSI) in a Kenyan rural hospital.
Methods
A total of 3317 patients undergoing clean and clean-contaminated surgery were included. Follow-up data 30 days after discharge were available for 3133 patients (94·5 per cent).
Results
SSI occurred in 255 patients (8·1 per cent), with similar rates for both study arms: 8·3 per cent for alcohol-based handrub versus 8·0 per cent for plain soap and water (odds ratio 1·03, 95 per cent confidence interval 0·80 to 1·33). After adjustment for imbalances between study arms and clustering effects, the main outcome measure remained unchanged (adjusted odds ratio 1·06, 0·81 to 1·38). The duration of surgery and wound contamination class independently predicted SSI. The cost difference between the methods was small (€4·60 per week for alcohol-based handrub compared with €3·30 for soap and water).
Conclusion
There was no statistically or clinically significant difference in SSI rates, probably because more important factors contribute to SSI development. However, this study demonstrated the feasibility and affordability of alcohol-based handrubs for hand preparation before surgery in settings without continuous, clean water. Registration number: NCT00987402 (http://www.clinicaltrials.gov).

Abstract
Successive point prevalence surveys were conducted in November 2007 and 2008 to monitor the prevalence of healthcare-associated infection (HCAI) in 13 grade III, 1st class hospitals in Hubei Province of China, using the case definition criteria established by the Ministry of Health in the People's Republic of China. In total, of 20 350 patients surveyed, 833 (4.09%) HCAIs were observed in 790 (3.88%) patients. There was no significant difference between the overall prevalence of HCAI in 2007 (4.14%) and 2008 (3.72%). Respiratory tract infection was the most common HCAI (63.15%), followed by surgical site infection (9.60%) and urinary tract infection (8.64%). Only 35.29% (294/833) of HCAI patients had positive microbiology results. Gram-negative bacteria were isolated most frequently and the most frequent organism was Pseudomonas aeruginosa, followed by Escherichia coli, Acinetobacter baumannii and Staphylococcus aureus. Antibiotic use was documented for 10,344 (50.83%) patients, and cephalosporins, penicillins, and quinolones were the most commonly used agents for treatment or prophylaxis.

Abstract
OBJECTIVE The objective of the study was to determine whether vaginal preparation with povidone iodine before cesarean delivery decreased the risk of postoperative maternal morbidities. STUDY DESIGN The design of the study was a randomized, controlled trial in women undergoing cesarean delivery with subjects assigned to have a preoperative vaginal cleansing with povidone iodine or to a standard care group (no vaginal wash). The primary outcome was a composite of postoperative fever, endometritis, sepsis, readmission, wound infection, or complication. RESULTS There were 155 vaginal cleansing subjects and 145 control subjects. Overall, 9.0% developed the composite outcome, with fewer women in the cleansing group (6.5%) compared with the control group (11.7%), although the difference was not statistically significant (relative risk, 0.55; 95% confidence interval, 0.26-1.11; P = .11). Length of surgery, being in labor, and having a dilated cervix were all associated with the composite morbidity outcome. CONCLUSION Vaginal cleansing with povidone iodine before cesarean delivery may decrease postoperative morbidities, although the reduction is not statistically significant.

Abstract
OBJECTIVE To investigate whether the reduction effect due to participation in a nosocomial infection surveillance system for laboratory-confirmed central venous catheter (CVC)-associated primary bloodstream infection (BSI), ventilator-associated pneumonia (VAP), and surgical site infection (SSI) is reproducible for different time periods, independent of confounding factors that might occur during a specific time period. METHODS Data from the German national nosocomial infection surveillance system from the period January 1997 through June 2008 were used. CVC-associated BSI data and SSI data were analyzed for 3 starting periods, and VAP data were analyzed for 2 starting periods. Monthly infection rates were calculated for the following 36 months, and relative risks comparing the first and third surveillance years of each period were calculated. RESULTS A total of 2,399 CVC-associated BSI cases from 267 intensive care units, 3,637 VAP cases from 150 intensive care units, and 829 SSIs following 3 different procedures from 113 departments were analyzed. A significant reduction in VAP was shown for both starting periods investigated (overall relative risk [RR], 0.80 [95% CI, 0.74-0.86]). A significant reduction in CVC-associated BSI was demonstrated for 2 of 3 starting periods (overall RR, 0.83 [95% CI, 0.75-0.91]). A significant reduction in SSI was found for 2 starting periods for knee prosthesis insertion (overall RR, 0.56 [95% CI, 0.38-0.82]), for all of the 3 starting periods for cesarean delivery (overall RR, 0.75 [95% CI, 0.61-0.93]), and for none of the 3 starting periods for endoscopically performed cholecystectomy (overall RR, 0.89 [95% CI, 0.62-1.27]). CONCLUSIONS The surveillance effect, manifest as a significant reduction of nosocomial infection rates between the first and third years of participation in a surveillance system, was observed independently from the calendar year in which the surveillance activities started.

Abstract
This study presents data for ventilator use and ventilator-associated pneumonia (VAP) rates from the German hospital surveillance system for nosocomial infections (KISS: Krankenhaus Infektions Surveillance System). New Centers for Disease Control and Prevention (CDC) definitions became effective during 2005 and we describe the new method used by KISS to determine individual units with data at extreme ranges. The number of VAP cases per 1000 device-days was calculated and a new visual method, specifically funnel plots, was introduced to identify outliers. The VAP rate will be highly influenced by chance variability if only a few VAP cases are observed during a low number of ventilator-days. Funnel plots take this relationship between event rate and volume of cases into account. A total of 391 intensive care units (ICUs) reported surveillance data from 8 86 816 patients and included 6896 VAPs and 3 113 983 patient-days for the period January 2005 to December 2007. The mean VAP rate according to the new CDC definitions was 5.5 cases per 1000 ventilator-days (median: 4.4). The mean ventilator use in all ICUs was 35.7 (median: 29.3). Funnel plots identified 14.3% as outliers; 34 of them as high, and 22 as low, outliers. Since 2008, visual feedback to the KISS ICUs has been supplied by funnel plots. These are less prone to misinterpretation than histograms and they indicate when investigation is required for increasing VAP.

Abstract
Background: Surveillance of surgical site infections (SSI) provides data upon which interventions to improve patient safety can be based. In Thailand, however, SSI surveillance has not yet been standardized. Objectives: To develop a standardized SSI surveillance system and to monitor SSI rates after introduction of such a system. Methods: We conducted a prospective study among 17,752 patients who underwent surgery in ten hospitals in Thailand from April 2004 to May 2005. The SSI rates were computed and benchmarked with the US rates, reported in terms of standardized infection ratio (SIR). We estimated the incidence rate ratio of surgical site infections by comparing the incidence in the last study period with the incidence in the first study period. Results: The study included 17,869 operations and identified 248 SSIs, yielding an SSI rate of 1.4 infections/100 operations and a corresponding SIR of 0.6 (95% confidence interval [CI] = 0.5–0.7). During the study period the overall SSI rate decreased from 1.8 infections/100 operations to 1.2 infections/100 operations, yielding an incidence rate ratio of 0.65 (95% CI = 0.47–0.89). Conclusion: Our study highlighted that a standardized SSI surveillance in a developing country can be initiated through a network and may be followed by a decrease in SSI rates.

Abstract
The patient's external environment plays a significant, and in some cases dominant, role in his or her infection risk. The use of ultraclean air for certain procedures, as well as avoidance of hypothermia have been proven to reduce the risk of infection. There is no data to support the routine use of surgical masks (by surgeons or staff), ventilating helmets, or routine cleaning of all environmental surfaces in between cases. More research needs to be done in order to determine whether OR design changes, in addition to increasing OR efficiency and thus reducing case times, can also reduce infection rates. Further research is also needed to determine whether or not double gloves and/or the use of antiseptic scrubbing in addition to painting are efficacious.

Abstract
OBJECTIVE To present healthcare-acquired infection surveillance data for 2001-2005 in Queensland, Australia. DESIGN Observational prospective cohort study. SETTING Twenty-three public hospitals in Queensland. METHODS We used computer-assisted surveillance to identify episodes of surgical site infection (SSI) in surgical patients. The risk-adjusted incidence of SSI was calculated by means of a risk-adjustment score modified from that of the US National Nosocomial Infections Surveillance System, and the incidence of inpatient bloodstream infection (BSI) was adjusted for risk on the basis of hospital level (level 1, tertiary referral center; level 2, large general hospital; level 3, small general hospital). Funnel and Bayesian shrinkage plots were used for between-hospital comparisons. PATIENTS A total of 49,804 surgical patients and 4,663 patients who experienced healthcare-associated BSI. RESULTS The overall cumulative incidence of in-hospital SSI ranged from 0.28% (95% confidence interval [CI], 0%-1.54%) for radical mastectomies to 6.15% (95% CI, 3.22%-10.50%) for femoropopliteal bypass procedures. The incidence of inpatient BSI was 0.80, 0.28, and 0.22 episodes per 1,000 occupied bed-days in level 1, 2, and 3 hospitals, respectively. Staphylococcus aureus was the most commonly isolated microorganism for SSI and BSI. Funnel and shrinkage plots showed at least 1 hospital with a signal indicating a possible higher-than-expected rate of S. aureus-associated BSI. CONCLUSIONS Comparisons between hospitals should be viewed with caution because of imperfect risk adjustment. It is our view that the data should be used to improve healthcare-acquired infection control practices using evidence-based systems rather than to judge institutions.

Abstract
OBJECTIVE The purpose of this study was to examine the effect of a change in policy regarding the timing of antibiotic administration on the rates of postcesarean delivery surgical-site infections (SSI). STUDY DESIGN This was a retrospective cohort study of 1316 term, singleton cesarean deliveries at 1 institution. A policy change was instituted wherein prophylactic antibiotics were given before skin incision rather than after cord clamp. The primary outcome that was examined was SSI; secondary outcomes were the rates of endometritis and cellulitis. Multivariable regression was performed to control for potential confounders. RESULTS The overall rate of SSI fell from 6.4-2.5% (P = .002). When we controlled for potential confounders, there was a decline in overall SSI with an adjusted odds ratio (aOR) of 0.33 (95% CI, 0.14,0.76), a decrease in endometritis (aOR, 0.34; 95% CI, 0.13,0.92), and a trend towards a decrease in cellulitis (aOR, 0.22; 95% CI, 0.05,1.22). CONCLUSION At our institution, a change in policy to administer prophylactic antibiotics before skin incision led to a significant decline in postcesarean delivery SSIs.

Abstract
PURPOSE OF REVIEW To evaluate the recent literature on new randomized controlled trials and metaanalyses investigating infection control measures in the ICU. The focus is on ventilator-associated pneumonia, urinary tract infections and surgical site infections. RECENT FINDINGS At least 10 randomized controlled studies and 11 metaanalyses were published last year investigating various infection control measures for preventing ventilator-associated pneumonia, urinary tract infections and surgical site infections in ICU patients. They endorsed existing recommendations and led to some changes in the present guidelines. One of the most interesting findings was evidence for the routine use of oral chlorhexidine gluconate rinse to decrease ventilator-associated pneumonia rates. Furthermore, several cohort studies with a before-after design were published and demonstrated a substantial reduction in infection rates by introducing multimodal infection control programs. SUMMARY There is currently enormous interest in the field of infection control in ICU patients. Experts in this field are aiming to summarize existing knowledge on decreasing nosocomial infection rates and to update guidelines. Translating infection prevention evidence into practice, however, is also a very import element of ICU infection control and should be the main focus of further studies.

Abstract
INTRODUCTION Implantable pain therapy devices for chronic pain include spinal cord stimulators (SCS) and intrathecal drug delivery systems (IDDS). A number of different complications can occur after implantation of these devices, but among the most serious is infection. Based on Centers for Disease Control and Prevention guidelines for prevention of surgical site infection, published literature on infection risk with implantable pain therapy devices, and recommendations from groups within our own our institution, we introduced infection control measures for all patients receiving either SCS or IDDS. METHODS After approval from the Institutional Review Board, we performed a retrospective review of patients undergoing primary implantation of SCS or IDDS before and after introduction at our institution of safety measures designed to reduce device-related infection. We compared infection incidence and compliance to infection precautions before and after introduction of these measures. RESULTS Thirty-four SCS or IDDS were implanted before implementation of the infection control measures and 58 were placed after. Five device-related infections occurred. Adherence to most infection precautions improved during the study period, but 100% compliance was seen only with venue used for implantation. Infection incidence declined after introduction of the safety measures, but the reduction was not statistically significant. CONCLUSIONS Introduction of infection control measures for implantable pain therapy devices improved adherence to most infection precautions in our practice. Lack of specific documentation could have hindered practice surveillance within our group. A tool to document performance of infection control measures would be useful not only as a marker of compliance but could also serve as a reminder to perform certain safety measures.
