Incidence Analysis

Background: Prior studies suggest that cefazolin, widely used for antibiotic prophylaxis in hysterectomy, might not prevent surgical site infections (SSIs) as well as antibiotics with a broader antianaerobic antimicrobial spectrum. We compared the effectiveness of cefazolin versus antibiotic regimens with a broader antimicrobial spectrum in a ≥500-bed regional referral center. Methods: Study design: retrospective cohort. Population and setting: patients ≥18 years old who underwent hysterectomy between 1998 and 2018 at the University of Wisconsin Hospital. Analysis: propensity score matching with a caliper of 0.2 to select controls for cefazolin treatment, matching on: age, body mass index (BMI), diabetes, length of stay, duration of surgery, and preoperative renal function. We conducted a crude SSI incidence analysis and adjusted for additional covariates (malignancy, intraoperative temperature, and preoperative glucose level) using a Cox proportional hazards model. All analyses were conducted using STATA SE v15 software. Results: We had 4,087 hysterectomy patients, with 123 SSIs (3%). Among these SSIs, 46%, 11%, and 42% were superficial, deep, and organ-space, respectively. Malignancies were present in 83% of SSI patients, with 30% being ovarian cancer. Risk factors for SSI in the unmatched sample multivariable analysis (MV) were length of stay (aHR, 1.1; 95% CI, 1.05–1.1; P < .001), duration of surgery (aHR, 1.2; 95% CI, 1.1–1.32; P < .001), and BMI (aHR, 1.04; 95% CI, 1.02–1.06; P < .001). After propensity matching, 2,282 hysterectomies remained. In the crude incidence analysis, cefazolin (IR, 6.0) had a protective SSI effect compared to cefoxitin (IR, 7.1), ciprofloxacin/metronidazole (IR, 27.2), clindamycin/gentamicin (IR, 14.1), any antianaerobic regimen (IR, 8.0), and regimens not guideline recommended (IR, 11.7). In our MV analyses of cefazolin versus comparator antibiotic regimens, we found that hypothermia was consistently associated with a higher SSI risk (P ≤ .03). Receipt of a β-lactam antibiotic regimen was associated with a significantly lower SSI risk (aHR, 0.31; 95% CI, 0.11–0.89, P = .03), but cefazolin’s protective SSI effect was no longer statistically significant. Conclusions: We found that cefazolin had a lower SSI risk compared to other antibiotic regimens, including those with better antianaerobic spectrum, in our tertiary-care hospital’s 11-year high-risk cohort. Our analysis suggests that maintaining intraoperative normothermia and administering β-lactam antibiotic prophylaxis are important modifiable risk factors for SSI prevention.Funding: NoneDisclosures: None

Epidemiological Characteristics

Background and Objective.Enterococcal bloodstream infections (BSIs) cause morbidity and mortality in children. This study aims to describe the epidemiological characteristics of enterococcal BSI, to determine the risk factors for vancomycin-resistantEnterococcus(VRE) BSI, and to compare outcomes of VRE BSI and vancomycin-susceptibleEnterococcus(VSE) BSI in this population.Methods.A retrospective cohort study at a 418-bed tertiary care children's hospital in Philadelphia, Pennsylvania, examined the epidemiological characteristics of children hospitalized with enterococcal BSI during the period from 2001 through 2006. A nested case-control study compared patients with VRE BSI with control patients with VSE BSI. Analysis included regression modeling to identify independent risk factors for VRE BSI.Results.We identified 339 patients with enterococcal BSI during the study period, including 39 patients with VRE infection. Fifty-three patients (16%) died before hospital discharge. Risk factors for VRE included long-term receipt of mechanical ventilation (adjusted odds ratio [OR], 5.40 [95% confidence interval {CI}, 1.28-6.48]), receipt of immunosuppressive medications during the preceding 30 days (adjusted OR, 2.88 [95% CI, 1.40-20.78]), use of vancomycin during the 2 weeks before onset of bacteremia (adjusted OR per day of vancomycin use, 1.25 [95% CI, 1.14-1.38]), and older age (adjusted OR, 1.08 [95% CI, 1.03-1.14]). VRE BSI was not associated with an increased length of stay after onset of bacteremia (0.77 days [95% CI, 0.55-1.07 days]). Mortality was higher for VRE BSI, but the difference was not statistically significant (adjusted OR, 1.94 [95% CI, 0.78-4.8]).Conclusion.Most enterococcal BSI in children was caused by VSE. Risk factors for VRE BSI included receipt of vancomycin, long-term receipt of mechanical ventilation, immunosuppression, and older age. Differences in length of stay and mortality were not detected.

Background.Carbapenem-resistantKlebsiella pneumoniae(CRKP) is resistant to almost all antimicrobial agents, and CRKP infections are associated with substantial morbidity and mortality.Objective.To describe an outbreak of CRKP in Puerto Rico, determine risk factors for CRKP acquisition, and detail the successful measures taken to control the outbreak.Design.Two case-control studies.Setting.A 328-bed tertiary care teaching hospital.Patients.Twenty-six CRKP case patients identified during the outbreak period of February through September 2008, 26 randomly selected uninfected control patients, and 26 randomly selected control patients with carbapenem-susceptibleK. pneumoniae(CSKP) hospitalized during the same period.Methods.We performed active case finding, including retrospective review of the hospital's microbiology database and prospective perirectal surveillance culture sampling in high-risk units. Case patients were compared with each control group while controlling for time at risk. We sequenced theblaKPCgene with polymerase chain reaction for 7 outbreak isolates and subtyped these isolates with pulsed-field gel electrophoresis.Results.In matched, multivariable analysis, the presence of wounds (hazard ratio, 19.0 [95% confidence interval {CI}, 2.5-142.0]) was associated with CRKP compared with noK. pneumoniae.Transfer between units (adjusted odds ratio [OR], 7.5 [95% CI, 1.8-31.1]), surgery (adjusted OR, 4.0 [95% CI, 1.0-15.7]), and wounds (adjusted OR, 4.9 [95% CI, 1.1-21.8]) were independent risk factors for CRKP compared to CSKP. A novelK. pneumoniaecarbapenemase variant (KPC-8) was present in 5 isolates. Implementation of active surveillance for CRKP colonization and cohorting of CRKP patients rapidly controlled the outbreak.Conclusions.Enhanced surveillance for CRKP colonization and intensified infection control measures that include limiting the physical distribution of patients can reduce CRKP transmission during an outbreak.

Background.Antimicrobial stewardship programs (ASPs) decrease unnecessary antimicrobial use, decrease antimicrobial resistance, and improve patient outcomes. The effectiveness of a prior approval system—that is, the requirement that approval be obtained from ASP practitioners before certain antimicrobials can be used—depends on the accuracy of the patient data communicated from the primary service.Objectives.To determine the incidence of inaccurate communication of patient data during ASP interactions, describe examples of inaccurate communications, and identify risk factors for inaccurate communication.Design.We used a retrospective cohort design. We evaluated the communicated patient data for clinically important inaccuracies, using the patients' medical records as the gold standard.Setting.A tertiary care medical center that has a prior approval system for restricted antimicrobials.Patients.Inpatients discussed in telephone ASP interactions.Intervention.Observational study.Results.Of telephone calls requesting prior approval from ASP practitioners, 39% (95% confidence interval [CI], 31%-48%) contained an inaccuracy in at least 1 type of patient data (eg, current antimicrobial therapy); the incidence varied widely between data types. Examples of inaccuracies are given to demonstrate their clinical relevance. In multivariable analysis, inaccurate communications were more common for telephone calls from surgical services (versus calls from nonsurgical services: odds ratio, 2.1 [95% CI, 1.1-3.9]) and for calls received by Infectious Diseases fellows (versus pharmacists: odds ratio, 2.0 [95% CI, 1.1-3.8]).Conclusions.A high proportion of ASP calls requesting prior approval included patient data inaccuracies, which have the potential to affect the prescribing of antimicrobials. Although risk factors were identified, these communication errors were common across the different types of ASP interactions. Inaccurate communications may compromise the utility of ASPs that use a prior approval system for optimizing antimicrobial use.

A Prospective Study

Background: Prevention of Surgical site infection (SSI) remains a focus of attention because wound infections continue to be a major source of expense, morbidity, and even mortality. Three quarters of deaths of surgical patients with SSIs are attributed to nosocomial infections, nearly all of which are organ/space infections. The objective of the present study was to estimate the incidence of SSI and to study the various risk factors associated with SSI.Methods: This is a prospective study of 180 eligible cases eligible subjects, who underwent various surgeries in the department of General Surgery after applying inclusion and exclusion criteria. The study conducted at the Navodaya Medical College Hospital and Research Centre, Raichur. The tenure for the study was April 2017 to June 2017. Data was collected using pretested proforma. Data was analysed using SPSS version 16. Chi -square test and multiple logistic regression was applied to know the association between various risk factors and occurrence of SSI.Results: Among 180 patients 33 (18.33%) developed surgical site infections (SSI). Among 33 SSIs 25 (75.76%) were grade 3 and 8 (24.24%) were grade 4 infections. SSIs were found more commonly among patients over 50 years, diabetics, HIV infected patients, patients with longer duration of surgery and associations with these factors were found statistically significant.Conclusions: The incidence rate of SSI was quite high, and its end results will have a greater impact on patients as well as on healthcare systems. Prevention of SSI requires multipronged approach targeting both patient related and procedure related risk factors in pre- operative, intra-operative, and post-operative period.

OBJECTIVEHospital-acquired conditions (HACs) significantly compromise patient safety, and have been identified by the Centers for Medicare and Medicaid Services as events that will be associated with penalties for surgeons. The mitigation of HACs must be an important consideration during the postoperative management of patients undergoing spine tumor resection. The purpose of this study was to identify the risk factors for HACs and to characterize the relationship between HACs and other postoperative adverse events following spine tumor resection.METHODSThe 2008–2014 American College of Surgeons’ National Surgical Quality Improvement Program database was used to identify adult patients undergoing the resection of intramedullary, intradural extramedullary, and extradural spine lesions via current procedural terminology and ICD-9 codes. Demographic, comorbidity, and operative variables were evaluated via bivariate statistics before being incorporated into a multivariable logistic regression model to identify the independent risk factors for HACs. Associations between HACs and other postoperative events, including death, readmission, prolonged length of stay, and various complications were determined through multivariable analysis while controlling for other significant variables. The c-statistic was computed to evaluate the predictive capacity of the regression models.RESULTSOf the 2170 patients included in the study, 195 (9.0%) developed an HAC. Only 2 perioperative variables, functional dependency and high body mass index, were risk factors for developing HACs (area under the curve = 0.654). Hospital-acquired conditions were independent predictors of all examined outcomes and complications, including death (OR 2.26, 95% CI 1.24–4.11, p = 0.007), prolonged length of stay (OR 2.74, 95% CI 1.98–3.80, p < 0.001), and readmission (OR 9.16, 95% CI 6.27–13.37, p < 0.001). The areas under the curve for these models ranged from 0.750 to 0.917.CONCLUSIONSThe comorbidities assessed in this study were not strongly predictive of HACs. Other variables, including hospital-associated factors, may play a role in the development of these conditions. The presence of an HAC was found to be an independent risk factor for a variety of adverse events. These findings highlight the need for continued development of evidence-based protocols designed to reduce the incidence and severity of HACs.

AbstractObjective:To evaluate the impact of methicillin resistance in Staphylococcus aureus on mortality, length of hospitalization, and hospital charges.Design:A cohort study of patients admitted to the hospital between July 1, 1997, and June 1, 2000, who had clinically significant S. aureus bloodstream infections.Setting:A 630-bed, urban, tertiary-care teaching hospital in Boston, Massachusetts.Patients:Three hundred forty-eight patients with S. aureus bacteremia were studied; 96 patients had methicillin-resistant S. aureus (MRSA). Patients with methicillin-susceptible S. aureus (MSSA) and MRSA were similar regarding gender, percentage of nosocomial acquisition, length of hospitalization, ICU admission, and surgery before S. aureus bacteremia. They differed regarding age, comorbidities, and illness severity score.Results:Similar numbers of MRSA and MSSA patients died (22.9% vs 19.8%; P = .53). Both the median length of hospitalization after S. aureus bacteremia for patients who survived and the median hospital charges after S. aureus bacteremia were significantly increased in MRSA patients (7 vs 9 days, P = .045; $19,212 vs $26,424, P = .008). After multivariable analysis, compared with MSSA bacteremia, MRSA bacteremia remained associated with increased length of hospitalization (1.29 fold; P = .016) and hospital charges (1.36 fold; P = .017). MRSA bacteremia had a median attributable length of stay of 2 days and a median attributable hospital charge of $6,916.Conclusion:Methicillin resistance in S. aureus bacteremia is associated with significant increases in length of hospitalization and hospital charges.

<b><i>Introduction:</i></b> An increase in age has been observed among patients admitted to the intensive care unit (ICU). Age is a well-known risk factor for ICU readmission and mortality. However, clinical characteristics and risk factors of ICU readmission of elderly patients (≥65 years) have not been studied. <b><i>Methods:</i></b> This retrospective single-center cohort study was conducted in a total of 122-bed ICU of a tertiary care hospital in Seoul, Korea. A total of 85,413 patients were enrolled in this hospital between January 1, 2007, and December 31, 2017. The odds ratio of readmission and in-hospital mortality was calculated by logistic regression analysis. <b><i>Results:</i></b> Totally, 29,503 patients were included in the study group, of which 2,711 (9.2%) had ICU readmissions. Of the 2,711 readmitted patients, 472 patients were readmitted more than once (readmitted 2 or more times to the ICU, 17.4%). In the readmitted patient group, there were more males, higher sequential organ failure assessment (SOFA) scores, and hospitalized for medical reasons. Length of stay (LOS) in ICU and in-hospital were longer, and 28-day and in-hospital mortality was higher in readmitted patients than in nonreadmitted patients. Risk factors of ICU readmission included the ICU admission due to medical reason, SOFA score, presence of chronic heart disease, diabetes mellitus, chronic kidney disease, transplantation, use of mechanical ventilation, and initial ICU LOS. ICU readmission and age (over 85 years) were independent predictors of in-hospital mortality on multivariable analysis. The delayed ICU readmission group (&#x3e;72 h) had higher in-hospital mortality than the early readmission group (≤72 h) (20.6 vs. 16.2%, <i>p</i> = 0.005). <b><i>Conclusions:</i></b> ICU readmissions occurred in 9.2% of elderly patients and were associated with poor prognosis and higher mortality.

Abstract Background: The study analysed risk factors for bacterial and fungal co-infection in patients with COVID-19 and the impact on mortality.Methods: This is a single-center retrospective study conducted on 387 patients with confirmed COVID-19 pneumonia admitted to an Italian Tertiary-care hospital, between 21 February 2020 and 31 May 2020. Bacterial/fungal coinfection was determined by the presence of characteristic clinical features and positive culture results. Multivariable logistic regression was used to analyze risk factors for the development of bacterial/fungal co-infection after adjusting for demographic characteristics and comorbidities. Thirty-day survival of the patients with or without co-infections was analysed by Kaplan-Meier method.Results: In 53/387 (13.7%) patients with COVID-19 pneumonia, 67 episodes of bacterial/fungal co-infection occurred (14 presented >1 episode). Pneumonia was the most frequent co-infection (47.7%), followed by BSI (34.3%) and UTI (11.9%). S. aureus was responsible for 24 episodes (35.8%), E. coli for 7 (10.4%), P. aerugionsa and Enterococcus spp. for 5 episodes each (7.4%). Five (7.4%) pulmonary aspergillosis, 3 (4.4%) pneumocystosis and 5 (7.4%) invasive candidiases were observed. Multivariable analysis showed a higher risk of infection in patients with an age>65 years (csHR 2.680; 95%CI: 1.254 - 5.727; p=0.054), with cancer (csHR 5.243; 95%CI: 1.173-23.423; p=0.030), with a LOS>10 days (csHR 12.507; 95%CI: 2.659 – 58.830; p=0.001), early (within 48h) admitted in ICU (csHR 11.766; 95% CI: 4.353-31.804; p<0.001), and with a SOFA score>5 (csHR 3.397; 95% CI: 1.091 - 10.581; p=0.035). Estimated cumulative risk of developing at least 1 bacterial/fungal co-infection episode was of 15% and 27% after 15 and 30 days from admission, respectively. Kaplan-Meier estimated a higher cumulative probability of death in patients with bacterial/fungal co-infection (log-rank=0.031). Thirty-day mortality rate of patients with pneumonia was 38.7%, higher than those with BSI (30.4%).Conclusions: Bacterial and fungal infections are a serious complication affecting the survival of patients with COVID-19-related pneumonia. Some issues need to be investigated, such as the best empirical antibiotic therapy and the need for possible antifungal prophylaxis.

Objective To characterize and identify risk factors for 30-day surgical site infections (SSIs) in patients with head and neck cancer who underwent microvascular reconstruction. Study Design Cross-sectional study with nested case-control design. Setting Nine American tertiary care centers. Subjects and Methods Hospitalized patients were included if they underwent head and neck cancer microvascular reconstruction from January 2003 to March 2016. Cases were defined as patients who developed 30-day SSI; controls were patients without SSI at 30 days. Postoperative antibiotic prophylaxis (POABP) regimens were categorized by Gram-negative (GN) spectrum: no GN coverage, enteric GN coverage, and enteric with antipseudomonal GN coverage. All POABP regimens retained activity against anaerobes and Gram-positive bacteria. Thirty-day prevalence of and risk factors for SSI were evaluated. Results A total of 1307 patients were included. Thirty-day SSI occurred in 189 (15%) patients; median time to SSI was 11.5 days (interquartile range, 7-17). Organisms were isolated in 59% of SSI; methicillin-resistant Staphylococcus aureus (6%) and Pseudomonas aeruginosa (9%) were uncommon. A total of 1003 (77%) patients had POABP data: no GN (17%), enteric GN (52%), and antipseudomonal GN (31%). Variables independently associated with 30-day SSI were as follows: female sex (adjusted odds ratio [aOR], 1.6; 95% CI, 1.1-2.2), no GN POABP (aOR, 2.2; 95% CI, 1.5-3.3), and surgical duration ≥11.8 hours (aOR, 1.9; 95% CI, 1.3-2.7). Longer POABP durations (≥6 days) or antipseudomonal POABP had no association with SSI. Conclusions POABP without GN coverage was significantly associated with SSI and should be avoided. Antipseudomonal POABP or longer prophylaxis durations (≥6 days) were not protective against SSI. Antimicrobial stewardship interventions should be made to limit unnecessary antibiotic exposures, prevent the emergence of resistant organisms, and improve patient outcomes.

AbstractObjective:To identify risk factors associated with surgical-site infections (SSIs) following cesarean sections.Design:Prospective cohort study.Setting:High-risk obstetrics and neonatal tertiary-care center in upstate New York.Patients:Population-based sample of 765 patients who underwent cesarean sections at our facility during 6-month periods each year from 1996 through 1998.Methods:Prospective surgical-site surveillance was conducted using methodology of the National Nosocomial Infections Surveillance System. Infections were identified during admission, within 30 days following the cesarean section, by read-mission to the hospital or by a postdischarge survey.Results:Multiple logistic-regression analysis identified four factors independently associated with an increased risk of SSI following cesarean section: absence of antibiotic prophylaxis (odds ratio [OR], 2.63; 95% confidence interval [CI95], 1.50-4.6; P=.008); surgery time (OR, 1.01; CI95, 1.00-1.02; P=.04); <7 prenatal visits (OR, 3.99; CI95, 1.74-9.15; P=.001); and hours of ruptured membranes (OR, 1.02; CI95,1.01-1.03; P=.04).Patients given antibiotic prophylaxis had significantly lower infection rates than patients who did not receive antibiotic prophylaxis (F=02), whether or not active labor or ruptured membranes were present.Conclusion:Among the variables identified as risk factors for SSI, only two have the possibility to be changed through interventions. Antibiotic prophylaxis would benefit all cesarean patients regardless of active labor or ruptured membranes and would decrease morbidity and length of stay. Women's healthcare professionals also must continue to encourage pregnant women to start prenatal visits early in the pregnancy and to maintain scheduled visits throughout the pregnancy to prevent perinatal complications, including postoperative infection.
