Systematic review of urological injury during caesarean section and hysterectomy

Introduction and hypothesisWe aim to review iatrogenic bladder and ureteric injuries sustained during caesarean section and hysterectomy.MethodsA search of Cochrane, Embase, Medline and grey literature was performed using methods pre-published on PROSPERO. Eligible studies described iatrogenic bladder or ureter injury rates during caesarean section or hysterectomy. The 15 largest studies were included for each procedure sub-type and meta-analyses performed. The primary outcome was injury incidence. Secondary outcomes were risk factors and preventative measures.ResultsNinety-six eligible studies were identified, representing 1,741,894 women. Amongst women undergoing caesarean section, weighted pooled rates of bladder or ureteric injury per 100,000 procedures were 267 or 9 events respectively. Injury rates during hysterectomy varied by approach and pathological condition. Weighted pooled mean rates for bladder injury were 212–997 events per 100,000 procedures for all approaches (open, vaginal, laparoscopic, laparoscopically assisted vaginal and robot assisted) and all pathological conditions (benign, malignant, any), except for open peripartum hysterectomy (6,279 events) and laparoscopic hysterectomy for malignancy (1,553 events). Similarly, weighted pooled mean rates for ureteric injury were 9–577 events per 100,000 procedures for all hysterectomy approaches and pathologies, except for open peripartum hysterectomy (666 events) and laparoscopic hysterectomy for malignancy (814 events). Surgeon inexperience was the prime risk factor for injury, and improved anatomical knowledge the leading preventative strategy.ConclusionsCaesarean section and most types of hysterectomy carry low rates of urological injury. Obstetricians and gynaecologists should counsel the patient for her individual risk of injury, prospectively establish risk factors and implement preventative strategies.

Rates of intravenous antibiotic starts among outpatient hemodialysis patients using NHSN dialysis event reporting, 2016–2020

Background: Nearly one-third of patients on hemodialysis receive intravenous (IV) antibiotics annually, but national data characterizing antibiotic use in this population are limited. Using NHSN surveillance data for outpatient dialysis facilities, we estimated temporal changes in the rate of IV antibiotic starts (IVAS) among hemodialysis patients as well as the proportion of IVAS that were not supported by a reported clinical indication. Methods: IVAS events were obtained from the NHSN Dialysis Event module between 2016 and 2020, excluding patients who were out of network, receiving peritoneal or home dialysis, or with unspecified vascular access. IVAS unsupported by documentation were defined as new IVAS without a collected or positive blood culture, pus, redness or swelling event, or an associated clinical symptom. Pooled mean rates of total and unsupported IVAS were estimated per 100 patient months yearly and stratified by vascular access type. Differences in IVAS rates by year were estimated with negative binomial regression. Results: Between 2016 and 2020, 7,278 facilities reported 648,410 IVAS events; 161,317 (25%) were unsupported by documentation (Table 1). In 2016, 3,340 (54%) facilities with ≥1 IVAS event reported an IVAS unsupported by documentation, which increased to 4,994 (73%) in 2020. Total IVAS rates decreased by an average of 8.2% annually (95% CI, 7.1%–9.3%; P < .001). The average annual percentage decrease did not differ significantly by vascular access site. The total IVAS rate was lowest in 2020 (2.17 per 100 patient months; 95% CI, 2.18–2.17). IVAS rates in 2020 were greatest for patients with catheter access (4.79 per 100 patient months; 95% CI, 4.75–4.83), followed by graft (1.71 per 100 patient months; 95% CI, 1.68–1.73), and lowest for patients with fistulas (1.30 per 100 patient months; 95% CI, 1.29–1.31). The overall pooled mean rate of unsupported IVAS was 0.64 per 100 patient months (95% CI, 0.63–0.64), which did not significantly change by year (Fig. 1). Conclusions: Total IVAS rates among outpatient hemodialysis patients have decreased since 2016, and rates among catheter patients remain highest compared to patients with fistulas or grafts. However, unsupported IVAS rates did not change, and the proportion of facilities reporting an unsupported IVAS increased annually. Targeted efforts to engage facilities with unsupported IVAS may help improve accurate reporting and prescribing practices.Funding: NoneDisclosures: None

Primary Ureteric Stent Insertion Under Local Anaesthetic or Sedoanalgesia in Non-pregnancy

Background and Objective To characterise the evidence surrounding local anaesthetic ureteric stent insertion (LAUSI) in contexts outside of pregnancy, a procedure typically performed under general anaesthetic (GAUSI), as it has never been the subject of a systematic review. Materials and Methods A systematic review of the Medline, EMBASE, PubMed, AMED, BNI, EMCARE, HMIC and PsycINFO databases was conducted to examine the published evidence in line with the Preferred Reporting Items of Systematic Review and Meta-analyses (PRISMA) guidelines surrounding the technique, patient demographics, setting, type of LA± sedoanalgesia used, cystoscopy and fluoroscopy usage, patient tolerability and pain, efficacy, complications and cost-effectiveness. Around 1,460 papers were systematically screened for inclusion. Results Seventeen studies were identified; one randomised controlled trials (RCT), four non-randomised comparative studies, and 12 case-series describing LAUSI. The 17 studies encompassed a total of some 1545 LAUSI. The clinical indications were similar to those for GAUSI. Successful LAUSI rate ranged from 71-98.9% in studies overall, with a pooled mean success rate of 89.3% overall (86.8% in LA only, 91.75% in LA ± sedoanalgesia). The tolerability of a LAUSI patient across 14 studies had a pooled mean rate of 91.8% (88.6% in LA only, 95% in LA ± sedoanalgesia). The procedure time was reported in seven studies, and it ranged from 5.35±0.87 to 65.0±27.5 minutes. The four comparative studies showed no difference in complication rates between LAUSI and GAUSI. All five studies reporting on cost-effectiveness showed LAUSI to be superior to GAUSI. Conclusions LAUSI is a safe, effective, and cost-effective alternative to GAUSI, which is under-utilised. Further research in the form of RCTs is required to formally establish its place and acceptability amongst urologists.

Is the routine placement of a feeding jejunostomy during esophagectomy worthwhile?-a systematic review and meta-analysis.

Malnutrition dramatically increases the risk of postoperative complications and delays patient recovery. Therefore, a feeding jejunostomy tube (FJT) is routinely placed during esophagectomy to maintain the postoperative nutrition supply. However, recently published studies have questioned the need of a FJT in every esophageal cancer patient. Because most patients can resume oral intake shortly after surgery, the nutrition-providing function of a FJT becomes much less critical. In contrast, FJT-related complications could be severe. Relevant publications were found out by systemic searching of four medical databases (PubMed, EMBASE, Medline, and Cochrane Center Register of Controlled Trials). By reading the titles and the abstracts, potentially relevant studies were screened from the search results. The incidence of postoperative complications and FJT-related complications were calculated and compared to evaluate the efficacy of a FJT. Eighteen studies were included in the meta-analysis. The no-FJT group had a similar or even lower incidence of postoperative complications [anastomotic leakage (AL), pulmonary complications, and wound infections] compared with the FJT group. Ileus and FJT site infections were the most common FJT-related complications. The incidence of ileus was approximately 6% (95% CI: 3-12%), and over 63% of the patients with an ileus required re-operation to relieve the obstruction. The pooled mean rate of FJT site infections was 7% (95% CI: 6-9%). Approximately 7% of patients had dysfunction (obstruction or dislocation) of the jejunostomy tube (95% CI: 3-14%). The non-selective placement of a FJT during esophagectomy provides few benefits to the patients and may even increase the risk of postoperative complications. Therefore, an intraoperative FJT should be selectively prescribed, but not routinely in the surgical treatment of esophageal cancer.

Progress in Preventing Bloodstream Infections in Hemodialysis: Data From the National Healthcare Safety Network, 2014–2018

Background: More than 450,000 patients receive outpatient hemodialysis in the United States. Patients on hemodialysis are at high risk of bloodstream infections (BSIs), which are associated with significant morbidity and mortality. National prevention efforts targeting hemodialysis facilities have resulted in widespread changes in practice, including modifications to central venous catheter (CVC) maintenance procedures. We analyzed dialysis event surveillance data submitted to the CDC NHSN to describe changes in BSI rates among hemodialysis outpatients from 2014 to 2018. Methods: Outpatient hemodialysis facilities report BSIs (ie, positive blood cultures collected in the outpatient setting or within 1 calendar day after hospital admission) and the number of hemodialysis outpatients treated during the first 2 working days of each month to the NHSN. For each BSI, the suspected source (ie, vascular access, another site, contamination, or uncertain) and vascular access type are indicated: CVC, arteriovenous fistula (AVF) or arteriovenous graft (AVG). Pooled mean rates (per 100 patient months) were calculated for BSIs, access-related BSIs (ARBSIs), and BSIs and ARBSIs were stratified by vascular access type. Annual BSI rate trends were evaluated using a negative binomial regression model, which treated patient months as an offset variable and included access type, year, and an access-year interaction variable. Results: More than 6,000 outpatient hemodialysis facilities reported 134,961 BSIs from 2014 to 2018. Of these BSIs, 102,505 (76%) were categorized as access related. CVCs were present in 63% of BSIs and 70% of ARBSIs. Pooled mean BSI rates decreased 27% from 0.64 to 0.47 per 100 patient months; rates of ARBSIs decreased 27% from 0.49 to 0.36 per 100 patient months. Significant decreases in event rates occurred across vascular access strata (Fig. 1). The reduction in BSI and ARBSI burden was most pronounced among patients with CVCs. BSI rates in patients with CVCs decreased 32% from 2.16 per 100 patient months to 1.46 (annual average decrease, 9.5%), and ARBSI rates in patients with CVCs decreased 32% from 1.83 per 100 patient months to 1.24 (annual average decrease, 9.4%). Conclusions: Substantial reductions in BSI and ARBSI rates among hemodialysis outpatients occurred during this 5-year period, and these reductions appear to be most prominent among CVC and AVF patients. Improvements in infection prevention and control practices, including CVC care, have likely contributed to these reductions. Additional efforts to increase the uptake of known prevention practices and to identify new strategies for prevention might contribute to continued decreases in infections among this highly vulnerable population.Funding: NoneDisclosures: None

Return to Sports After Surgical Treatment of Osteochondral Defects of the Talus: A Systematic Review of 2347 Cases.

Background:Osteochondral defects (OCDs) of the talus are found subsequent to ankle sprains and ankle fractures. With many surgical treatment strategies available, there is no clear evidence on return-to-sport (RTS) times and rates.Purpose:To summarize RTS times and rates for talar OCDs treated by different surgical techniques.Study Design:Systematic review; Level of evidence, 4.Methods:The literature from January 1996 to November 2018 was screened, and identified studies were divided into 7 different surgical treatment groups. The RTS rate, with and without associated levels of activity, and the mean time to RTS were calculated per study. When methodologically possible, a simplified pooling method was used to combine studies within 1 treatment group. Study bias was assessed using the MINORS (Methodological Index for Non-Randomized Studies) scoring system.Results:A total of 61 studies including 2347 talar OCDs were included. The methodological quality of the studies was poor. There were 10 retrospective case series (RCSs) that investigated bone marrow stimulation in 339 patients, with a pooled mean rate of RTS at any level of 88% (95% CI, 84%-91%); 2 RCSs investigating internal fixation in 47 patients found a pooled RTS rate of 97% (95% CI, 85%-99%), 5 RCSs in which autograft transplantation was performed in 194 patients found a pooled RTS rate of 90% (95% CI, 86%-94%), and 3 prospective case series on autologous chondrocyte implantation in 39 patients found a pooled RTS rate of 87% (95% CI, 73%-94%). The rate of return to preinjury level of sports was 79% (95% CI, 70%-85%) for 120 patients after bone marrow stimulation, 72% (95% CI, 60%-83%) for 67 patients after autograft transplantation, and 69% (95% CI, 54%-81%) for 39 patients after autologous chondrocyte implantation. The mean time to RTS ranged from 13 to 26 weeks, although no pooling was possible for this outcome measure.Conclusion:Different surgical treatment options for talar OCDs allow for adequate RTS times and rates. RTS rates decreased when considering patients’ return to preinjury levels versus return at any level.

Ten-year surveillance of central line–associated bloodstream infections in South Korea: Surveillance not enough, action needed

Central line-associated bloodstream infections (CLABSIs) are preventable health care-associated infections that can lead to increased mortality. Therefore, we investigated trends in CLABSI rates, and the factors associated with changing trends over a 10-year period using the Korean National Healthcare-associated Infections Surveillance System (KONIS). We investigated annual CLABSI rates from 2006 to 2015 in 190 KONIS-participating intensive care units (ICUs) from 107 participating hospitals. We collected data associated with hospital and ICU characteristics and analyzed trends using generalized autoregressive moving average models. The CLABSI pooled mean rate decreased from 3.40 in 2006 to 2.20 in 2015 (per 1,000 catheter-days). The trend analysis also showed a significant decreasing trend in CLABSI rates in unadjusted models (annual increase, -0.137; P < .001). After adjusting for hospital and ICU characteristics, significant decreasing trends were identified (annual increase, -0.109; P < .001). However, there were no significant changes in subgroups with non-university-affiliated hospitals, hospitals in metropolitan areas near Seoul, small hospitals (300-699 beds), or surgical ICUs. In South Korea, CLABSI rates have shown significant reductions in the past 10 years with participation in the KONIS. However, CLABSI rates may be reduced by encouraging more hospitals to participate in the KONIS and by improved policy support for hospitals lacking infection control resources.

Three years’ experience of dialysis event surveillance

The main study aim was to track infections, evaluate performance, and identify opportunities for improved practice since infections, especially those associated with multidrug-resistant organisms, are the second most common cause of death among end-stage renal disease patients. This study describes the establishment of baseline dialysis event surveillance at a large dialysis center. Every month, the dialysis center staff reported the total number of maintenance hemodialysis patients to the department of infection control and hospital epidemiology. The surveillance system for dialysis events included monthly monitoring of hemodialysis patients in outpatient settings for positive blood cultures, intravenous antimicrobial initiation, and local vascular access infections. We calculated the pooled mean rates of positive blood cultures, intravenous antimicrobial initiation, and local vascular access infections during the period from June 1, 2014 to September 30, 2017. Results indicated more dialysis events were attributed to the CVC than any other dialysis vascular access. Regardless of vascular access type, intravenous antimicrobial initiation was the most commonly reported dialysis-associated event. Dialysis events surveillance can be used to produce a decrease in both morbidity and mortality rates in hemodialysis patients.

Fixation Options Following Greater Trochanteric Osteotomies and Fractures in Total Hip Arthroplasty: A Systematic Review.

The optimal system for greater trochanteric fixation following osteotomy or fracture remains unknown. This systematic review aims to synthesize the available English-language literature on 5 commonly reported trochanteric fixation methods to quantify and compare rates of complications and reoperation. A comprehensive search of MEDLINE and Embase databases from January 1946 to June 2017 was performed for articles in English describing fixation of trochanteric osteotomies and fractures using wires, cables, cable-plate devices, claw or locking plates, and trochanteric bolts. Pooled mean rates of complications and reoperation with 95% confidence intervals (CIs) were analyzed using a random-effects model. Fifty-seven studies involving 10,956 hips were eligible for inclusion. Five studies had Level-III evidence and 52 had Level-IV evidence. The pooled mean rate of nonunion was 4.17% (95% CI, 3.21% to 5.13%; I = 79%) for wires, 5.07% (95% CI, 0.37% to 9.77%; I = 74%) for cables, 16.11% (95% CI, 10.85% to 21.37%; I = 89%) for cable-plate systems, 9.60% (95% CI, 2.23% to 16.97%; I = 59%) for claw or locking plates, and 12.42% (95% CI, 3.41% to 21.43%; I = 75%) for trochanteric bolts. Substantial heterogeneity in the data precluded formal statistical comparison of outcomes and complications between implants. Available literature on the various trochanteric fixation implants is heterogeneous and consists primarily of retrospective case series. Based on the current literature, it is difficult to support the use of one implant over another. Despite superior mechanical properties, rates of complication and reoperation following cable-plate fixation remains suboptimal, especially in complex revision scenarios. Additional rigorous prospective randomized and cohort studies are needed to make definitive recommendations regarding the most reliable method of trochanteric fixation. Therapeutic Level IV.

DSV-73 - Spinal Fusion Surgical Site Infections at an Acute Care Hospital: A Case Control Study

Background: Surgical site infections (SSI) lead to additional post-operative hospital-days, increased healthcare expenditures and increased morbidity and mortality of post-operative patients. In 2016, the spinal fusion SSI rate for at an acute care hospital was nearly 1.5 times higher than the Centers for Disease Control's National Health and Safety Network pooled mean rate.

Hepatitis C virus viremic rate in the Middle East and North Africa: Systematic synthesis, meta-analyses, and meta-regressions.

ObjectivesTo estimate hepatitis C virus (HCV) viremic rate, defined as the proportion of HCV chronically infected individuals out of all ever infected individuals, in the Middle East and North Africa (MENA).MethodsSources of data were systematically-gathered and standardized databases of the MENA HCV Epidemiology Synthesis Project. Meta-analyses were conducted using DerSimonian-Laird random-effects models to determine pooled HCV viremic rate by risk population or subpopulation, country/subregion, sex, and study sampling method. Random-effects meta-regressions were conducted to identify predictors of higher viremic rate.ResultsAnalyses were conducted on 178 measures for HCV viremic rate among 19,593 HCV antibody positive individuals. In the MENA region, the overall pooled mean viremic rate was 67.6% (95% CI: 64.9–70.3%). Across risk populations, the pooled mean rate ranged between 57.4% (95% CI: 49.4–65.2%) in people who inject drugs, and 75.5% (95% CI: 61.0–87.6%) in populations with liver-related conditions. Across countries/subregions, the pooled mean rate ranged between 62.1% (95% CI: 50.0–72.7%) and 70.4% (95% CI: 65.5–75.1%). Similar pooled estimates were further observed by risk subpopulation, sex, and sampling method. None of the hypothesized population-level predictors of higher viremic rate were statistically significant.ConclusionsTwo-thirds of HCV antibody positive individuals in MENA are chronically infected. Though there is extensive variation in study-specific measures of HCV viremic rate, pooled mean estimates are similar regardless of risk population or subpopulation, country/subregion, HCV antibody prevalence in the background population, or sex. HCV viremic rate is a useful indicator to track the progress in (and coverage of) HCV treatment programs towards the set target of HCV elimination by 2030.

Surveillance of dialysis events: 12-month experience at five outpatient adult hemodialysis centers in Kuwait.

Embedding dialysis surveillance scheme is associated with reductions in blood stream infection and antimicrobial consumption .The aim of this study was to establish baseline dialysis events (DE) rates; hospitalization, intravenous (IV) antibiotics start or a positive blood culture stratified by vascular access category and comparisons to published National Healthcare Safety Network (NHSN) rates. A retrospective review of DE was done between January to December 2012, in five outpatient adult hemodialysis center. The pooled mean rates of hospitalization among patients with fistulas, grafts, permanent and temporary catheters were 2.8, 5.7, 5.1, and 10.6 per 100 patient-months, respectively. For positive blood culture the pooled mean rates were 0.2, 1.0, 1.9 and 2.7 per 100 patient-months in these groups. The IV antibiotics starts event pooled mean rates were 5.9, 9.0, 11.8, and 11.2 per 100 patient-months. DE were significantly more common in patients with permanent and temporary catheters when compared with patients with fistulas and graft (p<0.001). Surveillance of DE rates in Kuwait revealed significantly lower mean rate of hospitalization and positive blood culture while IV antimicrobial start shows significantly higher mean rate when compared to published NHSN data.

Incidence and pathogen distribution of healthcare-associated infections in pilot hospitals in Egypt.

To report type and rates of healthcare-associated infections (HAIs) as well as pathogen distribution and antimicrobial resistance patterns from a pilot HAI surveillance system in Egypt. Prospective surveillance was conducted from April 2011 through March 2012 in 46 intensive care units (ICUs) in Egypt. Definitions were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Trained healthcare workers identified HAIs and recorded data on clinical symptoms and up to 4 pathogens. A convenience sample of clinical isolates was tested for antimicrobial resistance at a central reference laboratory. Multidrug resistance was defined by international consensus criteria. ICUs from 11 hospitals collected 90,515 patient-days of surveillance data. Of 472 HAIs identified, 47% were pneumonia, 22% were bloodstream infections, and 15% were urinary tract infections; case fatality among HAI case patients was 43%. The highest rate of device-associated infections was reported for ventilator-associated pneumonia (pooled mean rate, 7.47 cases per 1,000 ventilator-days). The most common pathogens reported were Acinetobacter species (21.8%) and Klebsiella species (18.4%). All Acinetobacter isolates tested (31/31) were multidrug resistant, and 71% (17/24) of Klebsiella pneumoniae isolates were extended-spectrum β-lactamase producers. Infection control priorities in Egypt should include preventing pneumonia and preventing infections due to antimicrobial-resistant pathogens.

Central Line–Associated Bloodstream Infection in Neonatal Intensive Care Units

Describe the epidemiology of central line-associated bloodstream infections (CLABSIs) in neonatal intensive care units (NICUs) participating in a standardized and mandatory CLABSI surveillance program. Retrospective cohort. Setting. We included patients admitted (April 2007-March 2011) to 7 level II/III NICUs who developed a CLABSI (as defined by the National Healthcare Safety Network). CLABSIs/1,000 central line-days and device utilization ratio were calculated; χ(2) test, Student t test, Kruskal-Wallis, and Poisson regression were used. Overall, 191 patients had 202 CLABSI episodes for a pooled mean rate of 4.0 CLABSIs/1,000 central line-days and a device utilization ratio of 0.20. Annual pooled mean CLABSI rates increased from 3.6 in 2007-2008 to 5.1 CLABSIs/1,000 central line-days in 2010-2011 (P - .01). The all-cause 30-day case fatality proportion was 8.9% (n = 17) and occurred a median of 8 days after CLABSI. Coagulase-negative Staphylococcus was identified in 112 (50.5%) cases. Staphylococcus aureus was identified in 22 cases, and 3 (13.6%) were resistant to methicillin. An underlying intra-abdominal pathology was found in 20% (40/202) of CLABSI cases, 50% of which were reported in the last year of study. When adjusted for mean birth weight, annual CLABSI incidence rates were independently associated with the proportion of intra-abdominal pathology (P = .007) and the proportion of pulmonary pathology (P = .016) reported. The increase in CLABSI rates in Quebec NICUs seems to be associated with an increased proportion of cases with underlying intra-abdominal and pulmonary pathologies, which needs further investigation.

A Year of Change: Nurse Unit Champions Reduce CLABSI on 5 Medical/Surgical Units

CLABSI rates remain higher than national and state benchmarks in our 500+ bed urban teaching hospital, 70% of central-line usage occurs outside the ICU. Despite our ability to greatly reduce CLABSI by focusing on standardizing policy and procedures for insertion and care and maintenance of CVC, rates on medical/surgical units remain increased. Our mean CLABSI rate in 2011 for our 5 medical/surgical units is 1.4/1000 CVC device days compared to NHSN pooled mean rate of 1/1000 CVC device days and the state mean rate of 0.67/1000 CVC device days.

Effect of Supersaturated Oxygen Delivery on Infarct Size After Percutaneous Coronary Intervention in Acute Myocardial Infarction

Myocardial salvage is often suboptimal after percutaneous coronary intervention in ST-segment elevation myocardial infarction. Posthoc subgroup analysis from a previous trial (AMIHOT I) suggested that intracoronary delivery of supersaturated oxygen (SSO(2)) may reduce infarct size in patients with large ST-segment elevation myocardial infarction treated early. A prospective, multicenter trial was performed in which 301 patients with anterior ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention within 6 hours of symptom onset were randomized to a 90-minute intracoronary SSO(2) infusion in the left anterior descending artery infarct territory (n=222) or control (n=79). The primary efficacy measure was infarct size in the intention-to-treat population (powered for superiority), and the primary safety measure was composite major adverse cardiovascular events at 30 days in the intention-to-treat and per-protocol populations (powered for noninferiority), with Bayesian hierarchical modeling used to allow partial pooling of evidence from AMIHOT I. Among 281 randomized patients with tc-99m-sestamibi single-photon emission computed tomography data in AMIHOT II, median (interquartile range) infarct size was 26.5% (8.5%, 44%) with control compared with 20% (6%, 37%) after SSO(2). The pooled adjusted infarct size was 25% (7%, 42%) with control compared with 18.5% (3.5%, 34.5%) after SSO(2) (P(Wilcoxon)=0.02; Bayesian posterior probability of superiority, 96.9%). The Bayesian pooled 30-day mean (+/-SE) rates of major adverse cardiovascular events were 5.0+/-1.4% for control and 5.9+/-1.4% for SSO(2) by intention-to-treat, and 5.1+/-1.5% for control and 4.7+/-1.5% for SSO(2) by per-protocol analysis (posterior probability of noninferiority, 99.5% and 99.9%, respectively). Among patients with anterior ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention within 6 hours of symptom onset, infusion of SSO(2) into the left anterior descending artery infarct territory results in a significant reduction in infarct size with noninferior rates of major adverse cardiovascular events at 30 days.

Multidrug-Resistant Acinetobacter baumannii in New York City—10 Years Into the Epidemic

Multidrug-Resistant <i>Acinetobacter baumannii</i> in New York City—10 Years Into the Epidemic

Special Report: Dialysis Surveillance Report: National Healthcare Safety Network (NHSN)—Data Summary for 2006

AbstractThirty‐two outpatient hemodialysis providers in the United States voluntarily reported 3699 adverse events to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) during 2006. These providers were previously enrolled in the Dialysis Surveillance Network. The pooled mean rates of hospitalization among patients with arteriovenous fistulas, grafts, permanent and temporary central venous catheters were 7.7, 9.2, 15.7, and 34.7 per 100 patient‐months, respectively. For bloodstream infection the pooled mean rates were 0.5, 0.9, 4.2, and 27.1 per 100 patient‐months in these groups. Among the 599 isolates reported, 461 (77%) represented access‐associated blood stream infections in patients with central lines, and 138 (23%) were in patients with fistulas or grafts. The microorganisms most frequently identified were common skin contaminants (e.g., coagulase‐negative staphylococci). In 2007, enrollment in NHSN opened to all providers of outpatient hemodialysis. Specific information is available at http://www.cdc.gov/ncidod/dhqp/nhsn_FAQenrollment.html.

Hospital-Wide Decrease in Nosocomial Infection Markers (NIMs) over a 6 Month Period in Comparison to Baseline Utilizing a Virtual Surveillance System

ISSUE: Hospital Acquired Infections (HAIs) contribute to increased morbidity and mortality, increase length of stay and increase costs for hospitalizations. Being a large teaching facility rendered it impossible for the Infection Control Department to perform hospital wide surveillance using conventional surveillance methods given the available resources. Traditional targeted surveillance methods are being utilized for all Intensive Care Units (adult, pediatric and neonatal) focusing on device related infections and benchmarking against the National Healthcare Safety Network (NHSN) pooled mean rates.

Infecção em idosos internados em instituição de longa permanência

To evaluate the occurrence of infection in elderly interned in long-term care facilities (LTCF) during 13 consecutive months. Fifty five elderly were evaluated according to infection and, reporting was standardized. The median age was 75 (66 81) years. The data set consisted of 20,896 patients-day (PD) of care during the period, with a total of 76 infections for a pooled mean rate of infections 3.20 per 1,000 PD of care. Patient infection rate was 63.6%. Prevalent topographies of infection were respiratory (50%), urinary tract (32%), skin and soft tissue (12%) and gastroenteritis (7%), with an infection rate for specific categories/1000 PD of 1.60, 1.01, 0.38, 0.21, respectively. Mortality infection rate was 5%. Microbiological agents were isolated in 30.5% of the infection episodes. Escherichia coli and Staphylococcus aureus were prevalent. Infection presented an elevated incidence in the elderly interned, but no unusual problem with infections was disclosed.
