Abstract
PURPOSE Laser endoscopic enucleation of the prostate (EEP) for benign prostatic obstruction has become increasingly prevalent worldwide. Considering the medical cost-savings and concomitantly fewer nosocomial infections, the feasibility of same-day postoperative discharge of patients who have undergone laser EEP in terms of its safety and effectiveness has become a subject matter of growing interest. We aimed to review those studies focussing on day-case surgery (DCS) in patients undergoing laser EEP. METHODS A systematic search was conducted using PubMed-MEDLINE and Web of Science databases until October 2022 with the following search terms: "same day discharge AND laser enucleation of the prostate", "day-case AND laser enucleation of the prostate", "same day surgery AND laser enucleation of the prostate" and "one day surgery AND laser enucleation of the prostate" by combining PICO (population, intervention, comparison, outcome) terms. We identified 15 eligible studies. RESULTS While 14 of the studies focussed on holmium laser EEP, one focused on thulium laser vapoenucleation of the prostate. We observed an improvement in functional parameters in all studies we reviewed, and DCS success and readmission rates ranged between 35.3-100% and 0-17.8%, respectively. The complication rates varied between 0 and 36.7%, most of the complicatons were Clavien-Dindo (CD) I and II. CD ≥ III complications did not significantly differ between same day discharge (SDD) and non-SDD groups in the studies. CONCLUSION Laser EEP is feasible and promising DCS treatment option delivering improved functional parameters compared to baseline values, and lower perioperative complication and readmission rates in certain patients.

Abstract
PURPOSE To systematically review studies focused on the feasibility and outcomes of outpatient endoscopic enucleation of the prostate for benign prostatic obstruction. METHODS A literature search was conducted through December 2022 using PubMed/Medline, Web of Science, and Embase databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. Risk of bias assessment was performed according to the Newcastle-Ottawa Scale for case control studies. RESULTS Of 773 studies, ten were included in the systematic review (n = 1942 patients) and four in the meta-analysis (n = 1228 patients). The pooled incidence of successful same-day discharge was 84% (95% CI 0.72-0.91). Unplanned readmission was recorded in 3% (95% CI 0.02-0.06) of ambulatory cases. In the reported criteria-selected patients submitted to SDD surgery, the forest plot suggested a lower rate of postoperative readmission (OR 0.56, 95% CI 0.34-0.91, p = 0.02) and complications (OR 0.69, 95% CI 0.48-1, p < 0.05) rates compared to standard protocols. CONCLUSION We provide the first systematic review and meta-analysis on SDD for endoscopic prostate enucleation. Despite the lack of randomized controlled trials, we confirm the feasibility and safety of the protocol with no increase in complications or readmission rate in well-selected patients.

Abstract
Mixed cardiogenic-septic shock (MS), defined as the combination of cardiogenic (CS) and septic (SS) shock, is often encountered in cardiac intensive care units. Herein, the authors compared the impact of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in MS, CS, and SS. Of 1,023 patients who received VA-ECMO from January 2012 to February 2020 at a single center, 211 with pulmonary embolism, hypovolemic shock, aortic dissection, and unknown causes of shock were excluded. The remaining 812 patients were grouped based on the cause of shock at VA-ECMO application: i) MS (n = 246, 30.3%), ii) CS (n = 466, 57.4%), iii) SS (n = 100, 12.3%). The MS group was younger and had lower left ventricular ejection fraction than the CS or SS group did. The 30 day and 1 year mortalities were the highest in SS (30 day mortality: 50.4% vs. 43.3% vs. 69.0%, p < 0.001 for MS versus CS versus SS, respectively; 1 year mortality: 67.5% vs. 53.2% vs. 81.0%, p < 0.001 for MS versus CS versus SS, respectively). Posthoc analysis showed that the 30 day mortality of MS was not different from CS, while the 1 year mortality of MS was worse than CS but better than SS. Venoarterial extracorporeal membrane oxygenation application for MS may help improve survival and should therefore be considered if indicated.

Abstract
Pseudomonas aeruginosa (P. aeruginosa) is among the most common pathogens associated with healthcare-acquired infections, and is often antibiotic resistant, causing significant morbidity and mortality in cases of P. aeruginosa bacteremia. It remains unclear how the incidence of P. aeruginosa bacteremia changed during the Coronavirus Disease 2019 (COVID-19) pandemic, with studies showing almost contradictory conclusions despite enhanced infection control practices during the pandemic. This systematic review sought to examine published reports with incidence rates for P. aeruginosa bacteremia during (defined as from March 2020 onwards) and prior to the COVID-19 pandemic. A systematic literature search was conducted in accordance with PRISMA guidelines and performed in Cochrane, Embase, and Medline with combinations of the key words (pseudomonas aeruginosa OR PAE) AND (incidence OR surveillance), from database inception until 1 December 2022. Based on the pre-defined inclusion criteria, a total of eight studies were eligible for review. Prior to the pandemic, the prevalence of P. aeruginosa was on an uptrend. Several international reports found a slight increase in the incidence of P. aeruginosa bacteremia during the COVID-19 pandemic. These findings collectively highlight the continued importance of good infection prevention and control and antimicrobial stewardship during both pandemic and non-pandemic periods. It is important to implement effective infection prevention and control measures, including ensuring hand hygiene, stepping up environmental cleaning and disinfection efforts, and developing timely guidelines on the appropriate prescription of antibiotics.

Abstract
Trauma patients face unique challenges that require coordination by social workers knowledgeable in the intricacies of trauma patient psychosocial support which is often achieved by obtaining ancillary consultations. The impact of employing a designated trauma social worker (DTSW) in the utilization of these consults has not been described. A retrospective review was conducted of trauma patients admitted to an academic, urban Level 1 trauma center. The pre-intervention cohort (n = 272) corresponded to patients admitted before the presence of a DTSW (01/2013 to 06/2013), while the post-intervention cohort (n = 282) corresponded to patients admitted afterward (09/2015 to 01/2016). Data collection included demographics, injury profile, and types of interdisciplinary or therapy consultations. Post-intervention patients were found to be older and admitted with more injuries. Supportive care, physical therapy and occupational therapy consultations were more likely to be obtained in the post-intervention cohort. Hospital length of stay remained unchanged. This study suggests that the implementation of a DTSW significantly facilitates the utilization of interdisciplinary consultations. Length of stay remains unchanged, suggesting that a DTSW helps to coordinate care in a timely manner without increasing the hospital stay. DTSW implementation may be considered in trauma centers where one does not currently exist.

Abstract
AIM To determine risk factors for MRSA colonization in a Level IV Neonatal Intensive Care Unit (NICU) independent of length of stay and gestational age in the context of a persistently circulating MRSA clone. DESIGN Retrospective matched case-control study. SETTING Level IV NICU PATIENTS: Infants admitted between April 4,2017- March 31,2018. METHODS Based on weekly surveillance cultures, infants who acquired MRSA were matched 1:1 with MRSA-negative control infants by duration of exposure (length of stay) and gestational age to determine risk factors for acquisition. RESULTS Fifty case infants were matched with controls. Isolates from 45 of the 50 cases were mupirocin-resistant and related by pulse-field gel electrophoresis. On matched univariable analysis, the following were significantly associated with a risk for MRSA acquisition: 1.Bed location in the acute area(P = 0.03), 2.Requirement of any level of respiratory support during the week prior to MRSA detection(P = 0.04), 3.Higher ATP pass rate (a measure of effectiveness of cleaning) during the week of and week prior(P = 0.01), 4.Higher MRSA colonization pressure during the week of and week prior(P< 0.0001), 5.Not having a hearing test during the time between the previous negative culture and MRSA acquisition(P = 0.01). A multivariable conditional logistic regression model (that excluded ATP pass rate) found that only colonization pressure was associated with acquisition of MRSA colonization. CONCLUSIONS In an outbreak setting, MRSA colonization pressure is significantly associated with MRSA acquisition in the NICU independent of length of stay and gestational age.

Abstract
BACKGROUND Postoperative SSI is a common and potentially serious complication in spine surgery. Seasonal variation occurs in rates of nosocomial infection, with higher rates found in the summer, during which hot, humid conditions may be optimal for proliferation of bacteria. This might also influence the rate of SSI. The purpose of the study was to examine seasonal variation in SSI after PLIF/TLIF surgery, including relationships with experience of surgeons and causal organisms. METHODS Cases with SSI after PLIF/TLIF surgery at 10 facilities between January 1, 2012, and December 31, 2014 were retrieved from a database. Infection was defined based on CDC guidelines for SSIs. Patients were followed for at least two years after surgery. Surgeries were examined in spring (April-June), summer (July-September), autumn (October-December), and winter (January-March). Seasonal variation and other factors with a potential association with SSIs were evaluated. RESULTS A total of 1174 patients (607 males, 567 females) who underwent PLIF/TLIF surgery were identified. The operations were PLIF (n = 667), TLIF (n = 443), MIS-PLIF (n = 27), and MIS-TLIF (n = 37). The total SSI rate for the 2-year period was 2.5% (29/1174), and the 2-year average SSI rates for surgeries in each season were spring, 2.6% (7/266); summer, 3.9% (13/335); fall, 1.3% (4/302); winter, 1.8% (5/271). The SSI rate was significantly higher in summer than non-summer (3.9% vs. 1.9%, p < 0.05). SSIs were caused by a variety of pathogens, including Gram-positive cocci, and Staphylococcus aureus was the most common pathogenic organism to cause SSI. CONCLUSION Seasonality should be taken into account in strategies for SSI prevention, with particular attention on mitigation of increased temperature and humidity in the summer and on infection caused by Gram-positive cocci and S. aureus.

Abstract
Objectives: To describe the evolution of day-case success rate over the years and to identify predictive factors for prolonged hospitalization or readmissions. Methods: Retrospective review of all consecutive day-case holmium laser enucleation of the prostate (HoLEP) performed by a single surgeon between January 2013 and February 2019 using a prospective database. Day-case success was defined as discharge within less than 12 hours from admission without any readmission within 48 hours after discharge. Protocol for day-case treatment included systematic bladder catheter insertion with continuous irrigation for ∼2 hours and catheter removal on postoperative day 1. Patients were reached by phone on postoperative day 1 to ensure voiding. For the descriptive statistics, an analysis of variance was performed. Univariate and multivariate analyses were used to identify risk factors. Results: A total of 266 patients were retrieved and dispatched as follows: group 1 (n = 88) from January 2013 to July 2015, group 2 (n = 89) from August 2015 to June 2017, and group 3 (n = 89) from July 2017 to February 2019. The overall success rate was 80.5% (214/266) over the study period. It significantly improved over time from 70% in group 1 to 84% in group 2 and 87% in group 3 (p = 0.014). In the meantime, the operating time and the total energy delivered to the tissue decreased from 77 minutes in the first group to 60.4 minutes in the second group and 55.4 minutes in the third group (p < 0.001), and from 95.2 kJ in the first group to 84 kJ in the second group and 77.9 kJ in the third group (p = 0.041). On multivariate analysis, the only risk factor significantly associated with day-case failure was prostate volume greater than 90 cc (odds ratio = 2.041, p = 0.047). Conclusion: Day-case HoLEP is a reliable and safe procedure with a high success rate. The surgeon's experience seems to be crucial to improve perioperative outcomes, but prostate volume greater than 90 cc remains associated with higher failure rates.

Abstract
BACKGROUND Novel quality improvement(QI) methods are needed to optimize healthcare costs and value. Our goal was to determine if Statistical Process Control(SPC), an industrial QI tool, could transform length of stay(LOS) into a process measure, identify outliers, and their impact on surgical outcomes. METHODS SPC was performed on an institutional colorectal resection database 1/1/13-5/1/2018 to identify outliers and compare outcome variables across outliers and non-outliers. Control charts analyzed the process performance of LOS over time. Control limits were set at ± 1 standard deviation(SD) from the mean. Measures were stable within these limits. RESULTS LOS was stable, with consistent annual rates and variation of outliers. Outliers had identifiable causes of variation that were significantly different from non-outliers(p < 0.05). The variation resulted in more complications, readmissions, and reoperations in outliers(p < 0.05). CONCLUSIONS SPC can be applied to LOS, a stable process measure with decreasing variability over time, and easy outlier identification. Identifying outliers can facilitate targeted quality improvement.

Abstract
BACKGROUND Patients with inflammatory bowel disease might be at increased risk of invasive bacterial infections. OBJECTIVES The objective of this study was to identify the rate of bacteremia in hospitalised patients with inflammatory bowel disease and risk factors. METHODS An observational cohort of hospitalised patients with inflammatory bowel disease, aged 16-80 years, from 2008 to 2017 in a large tertiary hospital. Patients with Charlson comorbidity index of 2 or greater were excluded. Patients with one or more positive blood culture were reviewed. Logistic regression was used to evaluate risk factors for bacteremia. RESULTS Of 5522 admitted patients, only 1.3% had bacteremia (73/5522) (39, Crohn's disease; 25, ulcerative colitis; nine, unclassified inflammatory bowel disease). The most common pathogen was Escherichia coli (19/73 patients). The mortality rate at 30 days of patients with bacteremia was 13.7% (10/73). Longer hospitalisations (mean length of stay (21.6 ± 31.0 vs. 6.4 ± 16.0 days; P < 0.0001) and older age (mean age 47.5 ± 18.0 vs. 40.2 ± 15.4 years, P < 0.0001)) were associated with an increased risk of bacteremia. In multivariate analysis, treatment with either anti-tumour necrosis factor α, purine analogues, steroids or amino salicylates was not associated with an increased risk of bacteremia. Risk was greatest among patients aged 65 years or older (relative risk 2.84, 95% confidence interval 1.6-4.8; P = 0.0001) relative to those under 65 years. CONCLUSION Age over 65 years, but not inflammatory bowel disease-related medications, is associated with an increased risk of bacteremia in hospitalised patients with inflammatory bowel disease.

Abstract
OBJECTIVE To determine risk factors independent of length of stay (LOS) for Staphylococcus aureus acquisition in infants admitted to the neonatal intensive care unit (NICU). DESIGN Retrospective matched case-case-control study. SETTING Quaternary-care referral NICU at a large academic children's hospital. METHODS Infants admitted between January 2014 and March 2016 at a level IV NICU who acquired methicillin resistant (MRSA) or susceptible (MSSA) S. aureus were matched with controls by duration of exposure to determine risk factors for acquisition. A secondary post hoc analysis was performed on the entire cohort of at-risk infants for risk factors identified in the primary analysis to further quantify risk. RESULTS In total, 1,751 infants were admitted during the study period with 199 infants identified as having S. aureus prevalent on admission. There were 246 incident S. aureus acquisitions in the remaining at-risk infant cohort. On matched analysis, infants housed in a single-bed unit were associated with a significantly decreased risk of both MRSA (P=.03) and MSSA (P=.01) acquisition compared with infants housed in multibed pods. Across the entire cohort, pooled S. aureus acquisition was significantly lower in infants housed in single-bed units (hazard ratio,=0.46; confidence interval, 0.34-0.62). CONCLUSIONS NICU bed design is significantly associated with S. aureus acquisition in hospitalized infants independent of LOS. Infect Control Hosp Epidemiol 2018;39:46-52.

Abstract
OBJECTIVES To evaluate host characteristics, mode of infection acquisition, and infection control procedures in patients with a positive respiratory syncytial virus (RSV) test result after the introduction of the GenXpert Influenza/RSV polymerase chain reaction (PCR) assay. DESIGN Retrospective cohort study. PATIENTS Adults with a positive PCR test result for RSV who were hospitalized in a tertiary academic medical center between January 2015 and December 2016 were included in this study. Our infection control policy applies contact isolation precautions only for immunocompromised patients. METHODS Patients were identified through 2 databases, 1 consisting of patients isolated because of RSV infection and 1 with automatically collected laboratory results. Baseline and clinical characteristics were collected through a retrospective medical chart review. The rate of and clinical factors associated with healthcare-associated RSV infections were evaluated. RESULTS In total, 108 episodes in 106 patients hospitalized with a positive Xpert RSV test result were recorded during the study period. Among them, 11 episodes were healthcare-associated infections (HAIs) and 97 were community-acquired infections (CAIs). The mean length of hospital stay (LOS, 40.2 vs 11.2 days), the mean number of room switches (3.5 vs 1.7) and ward switches (1.5 vs 0.4), and the mean numbers of contact patients (9.9 vs 3.8) were significantly longer and higher in the HAI group than in the CAI group (P<.0001). Surveillance of microbiology records and clinical data did not reveal evidence for a cluster or an epidemic during the 2-year observation period. CONCLUSIONS The introduction of a rapid molecular diagnostic test systematically applied to patients with influenza-like illness may challenge current infection control policies. In our study, patients with HAIs had a prolonged hospital stay and a high number of contact patients, and they switched rooms and wards frequently. Infect Control Hosp Epidemiol 2017;38:1291-1297.

Abstract
BACKGROUND Complex surgeries such as a pancreatoduodenectomy (PD) traditionally have long hospital stays (LOS). METHODS Patients who underwent elective PD at our institution from 8/2011-6/2015 were retrospectively examined. Interquartile ranges were calculated from LOS. Patient were compared between the highest quartile and the remainder of the cohort. RESULTS 492 patients had a median LOS of 9 days, with 106 (22%) admitted for >14 days. Characteristics associated with prolong hospitalization include age (p = 0.004) and preoperative albumin <3.5 (p = 0.007). Significant intra-operative measures associated with prolonged LOS were blood loss (EBL, p = 0.004) and increased operative time (p = 0.008). Any complication extended hospitalizations (p < 0.001). Patients in the top quartile were less likely to be discharged home (p < 0.0001) and more likely to be readmitted (p < 0.0001). CONCLUSION Older patients with hypoalbuminemia are at higher risk of prolonged LOS following PD as well as high EBL, operative time, and surgical complications. Focused efforts to counsel and optimize patients pre-operatively and minimize intra-operative complications may shorten hospital stays.

Abstract
OBJECTIVE Although postoperative readmissions are frequent in vascular surgery patients, the reasons for these readmissions are not well characterized, and effective approaches to their reduction are unknown. Our aim was to analyze the reasons for vascular surgery readmissions and to report potential areas for focused efforts aimed at readmission reduction. METHODS The 2012 to 2013 American College of Surgeons National Quality Improvement Program (ACS NSQIP) data set was queried for vascular surgery patients. Multivariable models were developed to analyze risk factors for postdischarge infections, the major drivers of unplanned 30-day readmissions. RESULTS We identified 86,403 vascular surgery patients for analysis. Thirty-day readmission occurred in 8827 (10%), of which 8054 (91%) were unplanned. Of the unplanned readmissions, 61% (n = 4951) were related to the index vascular surgery procedure. Infectious complications were the most common reason for a surgery-related readmission (1940 [39%]), with surgical site infection being the most common type of infection related to unplanned readmission. Multivariable analysis showed the top five preoperative risk factors for postdischarge infections were the presence of a preoperative open wound, inpatient operation, obesity, work relative value unit, and insulin-dependent diabetes (but not diabetes managed with oral medications). Cigarette smoking was a weak predictor and came in tenth in the mode (overall C index, 0.657). When operative and postoperative factors were included in the model, total operative time was the strongest predictor of postdischarge infectious complications (odds ratio [OR] 1.2 for each 1-hour increase in operative time), followed by presence of a preoperative open wound (OR, 1.5), inpatient operation (OR, 2), obesity (OR, 1.8), and discharge to rehabilitation facility (OR, 1.7; P < .001 for all). Insulin-dependent diabetes, cigarette smoking, dialysis dependence, and female gender were also predictive, albeit with smaller effects (OR, 1.1-1.3 for all; P < .001). The overall fit of the multivariable model was fair (C statistic, 0.686). CONCLUSIONS Infectious complications dominate the reasons for unplanned 30-day readmissions in vascular surgery patients. We have identified preoperative, operative, and postoperative risk factors for these infections with the goal of reducing these complications and thus readmissions. Expected patient risk factors, such as diabetes, obesity, renal insufficiency, and cigarette smoking, were less important in predicting infectious complications compared with operative time, presence of a preoperative open wound, and inpatient operation. Our findings suggest that careful operative planning and expeditious operations may be the most effective approaches to reducing infections and thus readmissions in vascular surgery patients.

Abstract
Outcomes after surgeries involving physicians as patients have not been researched. This study compares postoperative adverse events between physicians as surgical patients and nonhealth professional controls.Using reimbursement claims data from Taiwan's National Health Insurance Program, we conducted a matched retrospective cohort study of 7973 physicians as surgical patients and 7973 propensity score-matched nonphysician controls receiving in-hospital major surgeries between 2004 and 2010. We compared postoperative major complications, length of hospital stay, intensive care unit (ICU), medical expenditure, and 30-day mortality.Compared with nonphysician controls, physicians as surgical patients had lower adjusted odds ratios (ORs) with 95% confidence intervals (CIs) of postoperative deep wound infection (OR 0.63, 95% CI 0.40-0.99; P < 0.05), prolonged length of stay (OR 0.68, 95% CI 0.62-0.75; P < 0.0001), ICU admission (OR 0.74, 95% CI 0.66-0.83; P < 0.0001), and increased medical expenditure (OR 0.80, 95% CI 0.73-0.88; P < 0.0001). Physicians as surgical patients were not associated with 30-day in-hospital mortality after surgery. Physicians working at medical centers (P < 0.05 for all), dentists (P < 0.05 for all), and those with fewer coexisting medical conditions (P < 0.05 for all) had lower risks for postoperative prolonged length of stay, ICU admission, and increased medical expenditure.Although our study's findings suggest that physicians as surgical patients have better outcomes after surgery, future clinical prospective studies are needed for validation.

Abstract
OBJECT Spinal metastases most commonly affect the vertebral bodies of the spinal column, and spinal cord compression is an indication for surgery. Commonly, an open posterior approach is employed to perform a transpedicular costotransversectomy or lateral extracavitary corpectomy. Because of the short life expectancies in patients with metastatic spinal disease, decreasing the morbidity of surgical treatment and recovery time is critical. One potential approach to decreasing morbidity is utilizing minimally invasive surgery (MIS). Although significant advances have been made in MIS of the spine, data supporting the utility of MIS are still emerging. This study compared outcomes of patients who underwent mini-open versus traditional open transpedicular corpectomy for spinal metastases in the thoracic spine. METHODS A consecutive cohort from 2006 to 2013 of 49 adult patients who underwent thoracic transpedicular corpectomies for spinal metastases was retrospectively identified. Patients were categorized into one of 2 groups: open surgery and mini-open surgery. Mini-open transpedicular corpectomy was performed with a midline facial incision over only the corpectomy level of interest and percutaneous instrumentation above and below that level. The open procedure consisted of a traditional posterior transpedicular corpectomy. Chi-square test, 2-tailed t-test, and ANOVA models were employed to compare perioperative and follow-up outcomes between the 2 groups. RESULTS In the analysis, there were 21 patients who had mini-open surgery and 28 patients who had open surgery. The mean age was 57.9 years, and 59.2% were male. The tumor types encountered were lung (18.3%), renal/bladder (16.3%), breast (14.3%), hematological (14.3%), gastrointestinal tract (10.2%), prostate (8.2%), melanoma (4.1%), and other/unknown (14.3%). There were no significant intergroup differences in demographics, comorbidities, neurological status (American Spinal Injury Association [ASIA] grade), number of corpectomies performed, and number of levels instrumented. The open group had a mean operative time of 413.6 minutes, and the mini-open group had a mean operative time of 452.4 minutes (p = 0.329). Compared with the open group, the mini-open group had significantly less blood loss (917.7 ml vs. 1697.3 ml, p = 0.019) and a significantly shorter hospital stay (7.4 days vs. 11.4 days, p = 0.001). There was a trend toward a lower perioperative complication rate in the mini-open group (9.5%) compared with the open group (21.4%), but this was not statistically significant (p = 0.265). At follow-up, there were no significant differences in ASIA grade (p = 0.342), complication rate after the 30-day postoperative period (p = 0.999), or need for surgical revision (p = 0.803). The open approach had a higher overall infection rate of 17.9% compared with that in the mini-open approach of 9.5%, but this was not statistically significant (p = 0.409). CONCLUSIONS The mini-open transpedicular corpectomy is associated with less blood loss and shorter hospital stay compared with open transpedicular corpectomy. The mini-open corpectomy also trended toward lower infection and complication rates, but these did not reach statistical significance.

Abstract
OBJECT Smoking is one of the leading causes of preventable morbidity and death in the U.S. and has been associated with perioperative complications. In this study, the authors examined the effects of smoking on perioperative outcomes and pseudarthrosis rates following anterior cervical corpectomy. METHODS All adult patients from 2006 to 2011 who underwent anterior cervical corpectomy were identified. Patients were categorized into 3 groups: patients who never smoked (nonsmokers), patients who quit for at least 1 year (quitters), and patients who continue to smoke (current smokers). Demographic, medical, and surgical covariates were collected. Multivariate analysis was used to define the relationship between smoking and blood loss, 30-day complications, length of hospital stay, and pseudarthrosis. RESULTS A total of 160 patients were included in the study. Of the 160 patients, 49.4% were nonsmokers, 25.6% were quitters, and 25.0% were current smokers. The overall 30-day complication rate was 20.0%, and pseudarthrosis occurred in 7.6% of patients. Mean blood loss was 368.3 ml and mean length of stay was 6.5 days. Current smoking status was significantly associated with higher complication rates (p < 0.001) and longer lengths of stay (p < 0.001); current smoking status remained an independent risk factor for both outcomes after multivariate logistic regression analysis. The complications that were experienced in current smokers were mostly infections (76.5%), and this proportion was significantly greater than in nonsmokers and quitters (p = 0.013). Current smoking status was also an independent risk factor for pseudarthrosis at 1-year follow-up (p = 0.012). CONCLUSIONS Smoking is independently associated with higher perioperative complications (especially infectious complications), longer lengths of stay, and higher rates of pseudarthrosis in patients undergoing anterior cervical corpectomy.

Abstract
Clostridium difficile is the leading cause of infectious diarrhea in
hospitalized patients. Integrating several infection control and prevention methods is a
burgeoning strategy for reducing disease incidence in healthcare settings. We present an
up-to-date review of the literature on ‘control bundles' used to mitigate the
transmission of this pathogen. All clinical studies of control bundles reported
substantial reductions in disease rates, in the order of 33%–61%.
Using a biologically realistic mathematical model we then simulated the efficacy of
different combinations of the most prominent control methods: stricter antimicrobial
stewardship; the administering of probiotics/intestinal microbiota transplantation; and
improved hygiene and sanitation. We also assessed the health gains that can be expected
from reducing the average length of stay of inpatients. In terms of reducing the rates of
colonization, all combinations had the potential to give rise to marked improvements. For
example, halving the number of inpatients on broad-spectrum antimicrobials combined with
prescribing probiotics or intestinal microbiota transplantation could cut pathogen
carriage by two-thirds. However, in terms of symptomatic disease incidence reduction,
antimicrobials, probiotics and intestinal microbiota transplantation proved substantially
less effective. Eliminating within-ward transmission by improving sanitation and reducing
average length of stay (from six to three days) yielded the most potent symptomatic
infection control combination, cutting rates down from three to less than one per 1000
hospital bed days. Both the empirical and theoretical exploration of C. difficile
control combinations presented in the current study highlights the potential gains that
can be achieved through strategically integrated infection control.

Abstract
BACKGROUND Contact with health care workers may be an important means of infection transmission between patients, yet little is known about patterns of patient contact with staff and visitors in hospitals. In a cross-sectional study, the frequency, type, and duration of contacts made by health care workers, other hospital staff, and visitors to patients in acute care settings were documented. METHODS Patients were observed in seven units of three academic hospitals, with recording of each occurrence of someone's entry into the patient's room. The health care worker's role, the duration of the visit, and the highest level of patient contact made were noted. Staff were also surveyed to determine their perception of how many patients per hour they come into contact with, how long they spend with patients, and the level of patient contact that occurs. FINDINGS Hourly room entries ranged from 0 to 28 per patient (median, 5.5), and patients received visits from 0 to 18 different persons per hour (median, 3.5). Nurses made the most visits (45%), followed by personal visitors (23%), medical staff (17%), nonclinical staff (7%), and other clinical staff (4%). Visits lasted 1 to 124 minutes (median, 3 minutes for all groups). Persons entering patients' rooms touched nothing inside the room, only the environment, the patient's intact skin, or the patient's blood/body fluids 22%, 33%, 27%, and 18% of the time, respectively. Medical staff estimated visiting an average of 2.8 different patients per hour (range, 0.5-7.0), and nursing staff estimated visiting an average of 4.5 different patients per hour (range, 0.5-18.0). CONCLUSIONS Examining patterns of patient contact may improve understanding of transmission dynamics in hospitals. New transmission models should consider the roles of health care workers beyond patients' assigned nurses and physicians.

Abstract
BACKGROUND Enhanced recovery after colon surgery has not been widely adopted in the United States and Europe, despite evidence that postoperative complications and hospital length of stay are decreased. OBJECTIVE We sought to evaluate the introduction of a comprehensive care process for enhanced recovery after colon surgery in 8 community hospitals. DESIGN A system-wide, surgeon-directed, multidisciplinary committee developed a comprehensive enhanced-care quality-improvement program. Surgeons and operations leaders in each hospital developed the internal structure to implement the process. PATIENTS Surgeons had the option of entering or not entering patients in the enhanced-care pathway. Other than trauma patients, there were no exclusion criteria. MAIN OUTCOME MEASURES To limit selection bias, the study population included all patients undergoing colon resections (those entered and not entered in the care process). Length of stay, postoperative days, hospital costs, 30-day readmission rate, and return to surgery for the study population were compared with a 2-year historical baseline. RESULTS Forty-two percent of the study population was entered in the enhanced-care process. The average length of stay and the number of postoperative days in the study population decreased by 1.5 (P < .0001) and 1.3 (P < .0001) days. The rate of readmissions and returns to surgery remained stable (P > .05), and the average hospital cost decreased by $1763 (P = .02). Generalized linear regression analysis demonstrated that the enhanced-care process was a more significant variable than was the surgical approach (laparoscopic vs open surgery) in decreasing length of stay. LIMITATIONS The degree of compliance with care process elements and the relative contribution of each element of the care process are unknown. CONCLUSIONS A comprehensive enhanced-care colon surgery care process was successfully introduced in a community hospital system, as indicated by the clinical outcome measures.

Abstract
BACKGROUND The purpose of this study was to determine whether trauma team oversight of patient management would positively affect efficiency of care as defined by improved patient throughput, with augmentation of both clinical and economic outcomes. METHODS All patients activating the trauma team at a level I trauma center during two time periods (last 6 months of 2005 and 2006) were reviewed. Trauma team activation criteria remained constant across the two time periods. During period one, patients were admitted to multiple services depending on injury pattern, whereas in period two, most patients were admitted to the trauma service for trauma team oversight of their management. In period two, improved documentation and appropriate coding were encouraged. Data are reported as mean +/- SD, and median. RESULTS Patient demographics, number of full-time trauma surgeons, and payer mix were similar during the two time periods. Trauma activations increased 150% (p < 0.05). The percentage of patients admitted to the trauma service increased (68% vs. 86%, p < 0.001). Median injury severity score (ISS) of admitted patients was unchanged, although mean ISS decreased (15 +/- 15 vs. 12 +/- 11, p < 0.0001). Hospital length of stay decreased (12 +/- 55 vs. 6 +/- 11, p < 0.0001). Linear regression analysis identified ISS and admission during the later time period as significant predictors of decreased length of stay. Changes in billings and coding practices resulted in statistically significant increases in trauma surgeon work-related relative value units (182% increase), charges (360% increase), and collections (280% increase). The increased system efficiency resulted in significant decreases in the actual hospital costs per patient and led to the generation of an overall net positive hospital contribution margin per patient. CONCLUSIONS Implementation of trauma team oversight of patient care resulted in increased efficiency of care delivery, with shorter hospital lengths of stay despite increased patient volume. This paradigm change, coupled with improved documentation and coding, resulted in improved reimbursement for the physician, and lower cost per discharge for the hospital.

Abstract
OBJECTIVE To estimate the independent effect of a single lower respiratory tract infection, urinary tract infection, or other healthcare-acquired infection on length-of-stay and variable costs and to demonstrate the bias from omitted variables that is present in previous estimates. DESIGN Prospective cohort study.Setting. A tertiary care referral hospital and regional district hospital in southeast Queensland, Australia. PATIENTS Adults aged 18 years or older with a minimum inpatient stay of 1 night who were admitted to selected clinical specialities. RESULTS Urinary tract infection was not associated with an increase in length of hospital stay or variable costs. Lower respiratory tract infection was associated with an increase of 2.58 days in the hospital and variable costs of AU $24, whereas other types of infection were associated with an increased length of stay of 2.61 days but not with variable costs. Many other factors were found to be associated with increased length of stay and variable costs alongside healthcare-acquired infection. The exclusion of these variables caused a positive bias in the estimates of the costs of healthcare-acquired infection. CONCLUSIONS The existing literature may overstate the costs of healthcare-acquired infection because of bias, and the existing estimates of excess costs may not make intuitive sense to clinicians and policy makers. Accurate estimates of the costs of healthcare-acquired infection should be made and used in appropriately designed decision-analytic economic models (ie, cost-effectiveness models) that will make valid and believable predictions of the economic value of increased infection control.

Abstract
PURPOSE Ours aims were to assess the feasibility of short stay after conservative breast surgery when giving the choice to women, to identify women characteristics associated to short (less than 48 hours) or conventional stay and to confront satisfaction and anxiety of the two groups. METHODS Women were able to choice the length of stay immediately after surgery. Afterwards they completed a questionnaire measuring pain, anxiety and satisfaction. Clinical data concerning surgery were also collected. RESULTS The hospital stay was short for 114 women (75.5%) and conventional for 37 women (24.5%). Length of stay was related to education level (P = 0,021), general health status (ASA score) (P = 0,003), breast pain (P = 0,001), the number of wound drains (P = 0,005), cancer (P = 0,001) and satisfaction about hospitalisation (P = 0,022). Post-surgical morbidity was similar between groups, except prolonged axillary drainage more frequent in conventional stay group. CONCLUSION Women often chose a short stay after breast conservative surgery. This procedure is feasible routinely without heavy complication. Women preference for a short stay is real and could be improved by a better organisation, which ensure the continuity of care between hospital and home, with satisfaction assessment.

Abstract
OBJECTIVES To describe the patterns of nosocomial infections in patients with traumatic injuries and to compare the associations between injury severity, derived from various severity scoring systems, and subsequent nosocomial infections. DESIGN Prospective observational study. SETTING A 750-bed university hospital serving as a medical school and referral center for the southern part of Thailand. PARTICIPANTS All trauma patients admitted to the hospital for more than 3 days during 1996 to 1999 were eligible for this study. METHODS The severity of injuries was measured in terms of injury severity score (ISS), revised trauma score (RTS), new injury severity score (NISS), and trauma injury severity score (TRISS). Infections acquired during hospitalization were categorized using Centers for Disease Control and Prevention criteria. The association between severity of injury and nosocomial infection was examined with Poisson regression models. RESULTS There were 222 nosocomial infections identified among 146 patients, yielding an infection rate of 0.8 infections per 100 patient-days. Surgical-site infection was the most common site-specific infection, accounting for 31.1% of all infections. The incidence of intravenous catheter-related bloodstream infection was 1.6 infections per 100 catheter-days. The bladder catheter-related urinary tract infection rate was 2.8 infections per 100 catheter-days. The rate of ventilator-associated pneumonia was 3.2 infections per 100 ventilator-days. The incidence of infection correlated well with injury severity. The infection incidence rate ratios for one severity category increment of ISS, NISS, RTS, and TRISS were 1.65 (95% confidence interval [CI95], 1.42 to 1.92), 1.79 (CI95, 1.55 to 2.05), 1.64 (CI95 1.43 to 1.88), and 1.32 (CI95, 1.14 to 1.52), respectively. CONCLUSIONS Surgical-site infection was the most common site-specific nosocomial infection. The NISS might be the most appropriate severity scoring system for adjustment of infection rates in trauma patients.

Abstract
STUDY DESIGN A prospective analysis of variations in monthly spinal infection rates at a spinal cord injury center with resident and fellow involvement in surgical care. OBJECTIVE To analyze the association between resident and fellow participation in spinal surgery and the incidence of perioperative wound infection over the academic year. SUMMARY OF BACKGROUND DATA It has been hypothesized that resident and fellow participation in surgical procedures may account for increased wound complications. Previous spinal infection studies have not addressed variations in the incidence of perioperative wound infections over the academic year. METHODS All cases of postoperative spinal infections at a spinal cord injury center from January 1994 through December 1997 were analyzed to determine whether monthly variations reflect the changes in surgical house officer experience through the academic year. RESULTS A statistically significant (P < 0.027) increase in the incidence of spinal infection was demonstrated for the month of January. No other significant variations in the monthly incidence of spinal infection existed. No significant differences were found when the data were analyzed: year-to-year (P < 0.727), season-to-season (P < 0.204), 4-month resident rotation (P < 0.061), and 6-month fellow rotation (P < 0.075). CONCLUSION A significantly higher incidence of spinal infection (10.5%) was observed for the month of January. Because January does not represent the start of a new resident or fellow rotation, there appears to be no association between the incidence of perioperative spinal wound infections and the level of experience of the surgical house officers in a regional spinal cord injury center.

Abstract
OBJECTIVES To determine the risk factors for acquisition of nosocomial primary bloodstream infections (BSIs), including the effect of nursing-staff levels, in surgical intensive care unit (SICU) patients. DESIGN A nested case-control study. SETTING A 20-bed SICU in a 1,000-bed inner-city public hospital. PATIENTS 28 patients with BSI (case-patients) were compared to 99 randomly selected patients (controls) hospitalized > or =3 days in the same unit. RESULTS Case- and control-patients were similar in age, severity of illness, and type of central venous catheter (CVC) used. Case-patients were significantly more likely than controls to be hospitalized during a 5-month period that had lower regular-nurse-to-patient and higher pool-nurse-to-patient ratios than during an 8-month reference period; to be in the SICU for a longer period of time; to be mechanically ventilated longer; to receive more antimicrobials and total parenteral nutrition; to have more CVC days; or to die. Case-patients had significantly lower regular-nurse-to-patient and higher pool-nurse-to-patient ratios for the 3 days before BSI than controls. In multivariate analyses, admission during a period of higher pool-nurse-to-patient ratio (odds ratio [OR]=3.8), total parenteral nutrition (OR=1.3), and CVC days (OR=1.1) remained independent BSI risk factors. CONCLUSIONS Our data suggest that, in addition to other factors, nurse staffing composition (ie, pool-nurse-to-patient ratio) may be related to primary BSI risk. Patterns in intensive care unit nurse staffing should be monitored to assess their impact on nosocomial infection rates. This may be particularly important in an era of cost containment and healthcare reform.

Abstract
OBJECTIVE To assess the relative importance of risk factors for surgical-site infections (SSIs) in orthopedic patients and thereby determine which risk factors to monitor in the national surveillance of SSI in The Netherlands. DESIGN Reanalysis of data on SSI and associated risk factors from two surveillance projects on nosocomial infections, carried out in 1992 and 1993 in The Netherlands: Project Surveillance Nosocomial Infections in the region of Utrecht (PSZU) and the first Project Surveillance Surgical Wound Infections (SWIFT-1). Odds ratios (ORs) were calculated for age, gender, preoperative stay, and the number of operations. In addition, in PSZU, other nosocomial infections, and, in SWIFT-1, prophylactic antibiotics, acute surgery, and wound contamination were studied. PARTICIPANTS The study was confined to hospitalized orthopedic patients (PSZU, 4,872; SWIFT-1, 6,437). RESULTS In PSZU, the following ORs were significant in a multivariate model: age 0-44 years, 1.0; 45-64 years, 1.6; 65-74 years, 4.7; and 75-99 years, 6.0. For a preoperative stay over 4 days, the OR was 3.3 (95% confidence interval [CI95], 2.5-4.0), and for multiple surgery, 2.5 (CI95, 1.9-3.0). For females, the OR was 0.8 (not significant). The same model applied to SWIFT-1 gave similar ORs. Adjustment for additional nosocomial infections (PSZU) decreased the ORs for ages over 65 years remarkably. The OR for additional nosocomial infections in patients under 65 years of age was 15.6 (CI95, 4.3-57.4). Adjustment for prophylactic antibiotics, acute surgery, and wound-contamination class (SWIFT-1) did not influence the ORs of the original model, but showed that wound-contamination class was an important risk factor. CONCLUSIONS Age, additional nosocomial infections, wound-contamination class, preoperative stay, and the number of operations were identified as important risk factors for SSI in Dutch orthopedic patients.

Abstract
OBJECTIVE To analyze the relationship between presentation with a community-acquired infection (CAI) and the risk of subsequent nosocomial infection, and the assessment of a likely diagnostic bias in this association. DESIGN A prospective cohort study. APACHE-II and TISS were used to assess severity and therapeutic intensity, respectively. Nosocomial infection (NI) was diagnosed according to SENIC and CDC diagnostic criteria. The relative risk and its 95% confidence interval were estimated. SETTING The intensive care unit (ICU) of the University of Granada Hospital (Spain). It is a ten-bed multidisciplinary unit. PATIENTS 448 patients admitted to the intensive care unit (ICU) between December-1986 and April-1988 who stayed at the ICU for at least 24 hours were included in the study. RESULTS The crude analysis suggests that CAI may prevent NI. When data were stratified by other variables a previous infection acted as a preventive factor in patients admitted to the ICU from emergency room, in patients with lower severity level and in those with shorter stay lengths at ICU. Patients with a CAI showed higher severity; they were treated more aggressively, they had a longer stay at ICU before a NI was diagnosed and they remained at ICU longer. In multivariate analysis the NI risk in patients with a CAI compared with those not infected previously and controlling for other variables was of 0.36. CONCLUSION The presence of a CAI may introduce a differential information bias in the study of NI.

Abstract
This study was carried out in order to assess the validity of the pure cross-sectional study in the ascertainment of nosocomial infection risk-factors. The results yielded by two designs (cross-sectional and case-control) are compared. A cross-sectional design was performed in a tertiary hospital. 592 patients were studied, 38 of whom were nosocomially infected. The clinical information on all the patients included in this design was reviewed after hospital discharge. A matched case-control study was nested in the population cross-sectionally surveyed. 66 cases (28 additional patients developed a hospital infection) and 132 controls were selected. Odds ratios (ORs) for the risk factors analyzed by both designs were compared. There were no significant differences between the estimates yielded by both designs; however, a trend of lower OR estimates for the cross-sectional study was seen, which may be important for risk factors not strongly related to (low relative risk) nosocomial infection. Several factors which might account for the results observed (random error, bias introduced by matching) are discussed. It is suggested that pure cross-sectional designs for the study of risk factors of nosocomial infection may introduce a negative (toward-the-null) bias.

Abstract
Two different measures of hospital-acquired infection (HAI), risk per discharge and incidence rate, were used to analyse the incidence of 225 primary HAIs detected in 3,090 patients in an 11-month survey. Longer hospital stay was associated with a greater risk of developing HAI, but the strength of the association was different for the two measures used. Day-specific incidence rates were found to vary, with a peak between the 14th and 19th days of hospitalisation. Similar patterns were observed when the data were stratified by age, sex and operation. Methods for calculating HAI should control for the length of hospital stay. Further studies are required to clarify the mechanisms that affect the temporal pattern of incidence of HAI observed with length of hospitalisation.

Abstract
To evaluate the relationship between severity and nosocomial infection in critical patients, we have conducted a prospective study at the Intensive Care Unit of the University of Granada Hospital (Spain). Patients' severity was evaluated by APACHE II and TISS. We found a positive association with nosocomial infection risk for an APACHE II score greater than 12 points (RR = 2.45) and for first-day TISS greater than 20 points (RR = 2.51). With a multivariate analysis we did not find an association between APACHE II and nosocomial infection risk, but each TISS point suggests an infection risk increment of 6%. We concluded TISS may be considered a good infection risk predictor. TISS could also be taken into account when nosocomial infection rates from several ICUs are compared.

Abstract
Several authors have suggested that incidence density should be used in studying nosocomial infection. We assess several risk factors for hospital infection by two ratios, the incidence density ratio (IDR) and the relative risk (RR), in an historical cohort of 843 patients. The variables analyzed were: operation, its length, type of surgical wound, severity of underlying disease, and age. The IDR figures were always lower than those yielded by the RR. For example, the IDR for operated patients was 2.78, whereas RR yielded a figure of 6.46, or the IDR for patients greater than 60 years old was 0.96, whereas the RR achieved a significant value of 1.67. This suggests that the use of IDR to analyze risk factors for nosocomial infection improves comparability of results obtained in different hospital settings. Also, it may allow a more exact quantification of an effect. These facts influence implementation of nosocomial infection control measures.
