AbstractBackgroundSelective digestive decontamination (SDD) and selective oropharyngeal decontamination (SOD) regimens appear protective against ICU-acquired overall bacteraemia. These regimens can be factorized as topical antibiotic prophylaxis (TAP) with (SDD) or without (SOD) protocolized parenteral antibiotic prophylaxis (PPAP) using cephalosporins. Both TAP and cephalosporins are risk factors for enterococcal colonization although their impact on enterococcal bacteraemia within studies of SDD/SOD remains unclear.ObjectivesTo benchmark the enterococcal bacteraemia incidence within component (control and intervention) groups of SDD/SOD studies among ICU patients versus studies without intervention (observational groups).MethodsThe literature was searched for SDD/SOD studies reporting enterococcal bacteraemia incidence data. In addition, component groups of studies of various non-antibiotic interventions served to provide additional points of reference.ResultsThe mean incidence per 100 patients (and 95% CI) for enterococcal bacteraemia among 19 SDD/SOD studies was equally increased among concurrent control (2.1; 1.0%–4.7%) and intervention (2.3; 2.0%–2.7%) groups versus the benchmark incidence (0.8; 0.6%–1.2%) derived from 16 observational study groups and also versus 9 component groups from non-antibiotic studies. These higher incidences remained apparent (P < 0.02) in a meta-regression model adjusting for groupwide factors such as PPAP use, mechanical ventilation proportion, group mean length of stay >7 days and publication year.ConclusionsThe incidences of enterococcal bacteraemia within both concurrent control and intervention groups of SDD/SOD studies are unusually high compared with the literature-derived benchmark. The impact of parenteral cephalosporin used as PPAP additional to TAP on enterococcal bacteraemia incidence was indeterminate in this analysis.

AbstractSelective digestive decontamination (SDD) regimens, variously constituted with topical antibiotic prophylaxis (TAP) and protocolized parenteral antibiotic prophylaxis (PPAP), appear highly effective for preventing ICU-acquired infections but only within randomized concurrent control trials (RCCT’s). Confusingly, SDD is also a concept which, if true, implies population benefit. The SDD concept can finally be reified  in humans using the broad accumulated evidence base, including studies of TAP and PPAP that used non-concurrent controls (NCC), as a natural experiment. However, this test implicates overall population harm with higher event rates associated with SDD use within the ICU context.

Over Time

Background: Ventilator-associated pneumonia (VAP) represents the highest burden among all healthcare-associated infections (HAIs), with a particularly high rate in patients in neurosurgical ICUs. Numerous VAP risk factors have been identified to provide a basis for preventive measures. However, the impact of individual factors on the risk of VAP is unclear. The goal of this study was to evaluate the dynamics of various VAP risk factors given the continuously declining prevalence of VAP in our neurosurgical ICU. Methods: This prospective cohort unit-based study included neurosurgical patients who stayed in the ICU >48 consecutive hours in 2011 through 2018. The infection prevention and control (IPC) program was implemented in 2010 and underwent changes to adopt best practices over time. We used a 2008 CDC definition for VAP. The dynamics of VAP risk factors was considered a time series and was checked for stationarity using theAugmented Dickey-Fuller test (ADF) test. The data were censored when a risk factor was present during and after VAP episodes. Results: In total, 2,957 ICU patients were included in the study, 476 of whom had VAP. Average annual prevalence of VAP decreased from 15.8 per 100 ICU patients in 2011 to 9.5 per 100 ICU patients in 2018 (Welch t test P value = 7.7e-16). The fitted linear model showed negative slope (Fig. 1). During a study period we observed substantial changes in some risk factors and no changes in others. Namely, we detected a decrease in the use of anxiolytics and antibiotics, decreased days on mechanical ventilation, and a lower rate of intestinal dysfunction, all of which were nonstationary processes with a declining trend (ADF testP > .05) (Fig. 2). However, there were no changes over time in such factors as average age, comorbidity index, level of consciousness, gender, and proportion of patients with brain trauma (Fig. 2). Conclusions: Our evidence-based IPC program was effective in lowering the prevalence of VAP and demonstrated which individual measures contributed to this improvement. By following the dynamics of known VAP risk factors over time, we found that their association with declining VAP prevalence varies significantly. Intervention-related factors (ie, use of antibiotics, anxiolytics and mechanical ventilation, and a rate of intestinal dysfunction) demonstrated significant reduction, and patient-related factors (ie, age, sex, comorbidity, etc) remained unchanged. Thus, according to the discriminative model, the intervention-related factors contributed more to the overall risk of VAP than did patient-related factors, and their reduction was associated with a decrease in VAP prevalence in our neurosurgical ICU.Funding: NoneDisclosures: None

Background Mexico is still in the growing phase of the epidemic of coronary heart disease (CHD), with mortality increasing by 48% since 1980. However, no studies have analyzed the drivers of these trends. We aimed to model CHD deaths between 2000 and 2012 in Mexico and to quantify the proportion of the mortality change attributable to advances in medical treatments and to changes in population-wide cardiovascular risk factors. Methods We performed a retrospective analysis using the previously validated IMPACT model to explain observed changes in CHD mortality in Mexican adults. The model integrates nationwide data at two-time points (2000 and 2012) to quantify the effects on CHD mortality attributable to changes in risk factors and therapeutic trends. Results From 2000 to 2012, CHD mortality rates increased by 33.8% in men and by 22.8% in women. The IMPACT model explained 71% of the CHD mortality increase. Most of the mortality increases could be attributed to increases in population risk factors, such as diabetes (43%), physical inactivity (28%) and total cholesterol (24%). Improvements in medical and surgical treatments together prevented or postponed 40.3% of deaths; 10% was attributable to improvements in secondary prevention treatments following MI, while 5.3% to community heart failure treatments. Conclusions CHD mortality in Mexico is increasing due to adverse trends in major risk factors and suboptimal use of CHD treatments. Population-level interventions to reduce CHD risk factors are urgently needed, along with increased access and equitable distribution of therapies.

Abstract Background Antimicrobial stewardship programs (ASP) aim to improve appropriate antimicrobial use. Post-operative antibiotics are generally not necessary, especially those without surgical site infections risk factors (e.g. obesity). Few studies have described the impact of ASP interventions on patient outcomes especially in unique populations such as obstetrics. This study aims to evaluate the impact of ASP interventions on post-elective caesarean (eLSCS) oral antibiotic prophylaxis use and patient outcomes including SSI rates. Methods This pre-post quasi-experimental study was conducted over 9 months (2 months pre- and 7 months post-intervention) in all women admitted for eLSCS in our institution. Interventions included eLSCS surgical prophylaxis guideline dissemination, where a single antibiotic dose within 60 minutes before skin incision was recommended. Post-eLSCS oral antibiotics was actively discouraged in those without SSI risk factors. This was followed by ASP intervention notes (phase 1) for 3 months, and an additional phone call to the ward team for the next 7 months (phase 2). Phase 3 (next 6 months) constituted speaking to the operating consultant. The primary outcome was post-operative oral antibiotics prescription rates. Secondary outcomes included rates of 30-day post-operative SSI. Results A total of 1751 women was reviewed. Appropriateness of pre-operative antibiotic prophylaxis was 98% in our institution. There were 244 women pre-intervention, 274 in post-intervention phase 1, 658 in phase 2 and 575 in phase 3. Pre-intervention post-eLSCS antibiotic prescribing rates was 82% (200), which reduced significantly post-intervention to 54% (148) in phase 1, 50% (331) in phase 2 and 39% (226) in phase 3 (p&lt; 0.001). There was no significant difference in patients who developed post-operative SSI pre-post intervention (0.8%, 2 of 242 vs. 1.9%, 28 of 1479, p=0.420) and among who received post-operative oral antibiotics compared to those without (1.9%, 17 of 905 vs. 1.5%, 13 of 846, p=0.582). Conclusion ASP interventions can reduce post-eLSCS antibiotic prophylaxis rates without adversely impacting patient safety. Disclosures All Authors: No reported disclosures

Background and Purpose. Residing in “disadvantaged” communities may increase morbidity and mortality independent of individual social resources and biological factors. This study evaluates the impact of population-level disadvantage on incident ischemic stroke likelihood in a multiethnic urban population. Methods. A population based case-control study was conducted in an ethnically diverse community of New York. First ischemic stroke cases and community controls were enrolled and a stroke risk assessment performed. Data regarding population level economic indicators for each census tract was assembled using geocoding. Census variables were also grouped together to define a broader measure of collective disadvantage. We evaluated the likelihood of stroke for population-level variables controlling for individual social (education, social isolation, and insurance) and vascular risk factors. Results. We age-, sex-, and race-ethnicity-matched 687 incident ischemic stroke cases to 1153 community controls. The mean age was 69 years: 60% women; 22% white, 28% black, and 50% Hispanic. After adjustment, the index of community level disadvantage (OR 2.0, 95% CI 1.7–2.1) was associated with increased stroke likelihood overall and among all three race-ethnic groups. Conclusion. Social inequalities measured by census tract data including indices of community disadvantage confer a significant likelihood of ischemic stroke independent of conventional risk factors.

The Impact

Male sexual dysfunction includes erectile dysfunction (ED), ejaculation disorders, orgasmic dysfunctions, and disorders of sexual interest/desire. Although current epidemiologic research supports the high prevalence of ED worldwide, incidence data are limited. Furthermore, prevalence data on other male sexual dysfunctions are also limited whereas incidence data are lacking. These epidemiologic data vary widely due to the different definitions used, the method of sampling, and the unknown value of the instruments used to assess sexual dysfunction. Many of the epidemiologic studies are old and associated with poor methodology. Although risk factors for ED are well described, there are almost no data for risk factors in other sexual dysfunctions. The impact of modification of risk factors in sexual dysfunctions is extremely interesting. To provide evidence-based data, there is an urgent need for new, properly designed epidemiological research.

Aim. To study the influence of different risk factors on complications rate while treating pulpitis. Methods. Retrospective analysis of 130 patients with pulpitis outpatient’s cards, who were treated by vital and devitalized pulp extirpation without additional rehabilitation (63 patients) and with addition of individually selected rehabilitation program (67 patients), was carried out. The presence and rate of risk factors for complications in both study groups were analyzed, the level of their impact in complications formation was assessed. The data were processed by analysis of variance. Results. The most significant risk factors for developing complications while treating pulpitis were low local dental and general recovery potential, multiple foci of dental and periodontal infection, mastication muscles malfunction, malocclusion, mental disorders. 60% of patients had the combination of 3 and more risk factors, which in half of all cases were associated with developing complications, if endodontic treatment of pulpitis was not associated with individually selected rehabilitation. Rehabilitation included physiotherapy (if indicated), e.g. low-frequency alternating magnetic field, intra-channel iodine electrophoresis, individually selected homeopathic drugs, Bach flower essences and kinesiotherapy in addition to full mouth debridement. Conclusion. The impact of a range of risk factors, which can be revealed in conditions of common outpatient dental practice, on pulpitis treatment effectiveness was revealed. The addition of individually selected rehabilitation program, targeted on revealed risk factors elimination, to traditional pulpitis treatment decreases the complications rate.

As in past pandemics, co-circulating pathogens may play a role in the epidemiology of coronavirus disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In particular, experimental evidence indicates that influenza infection can up-regulate the expression of ACE2—the receptor of SARS-CoV-2 in human cells—and facilitate SARS-CoV-2 infection. Here we hypothesized that influenza impacted the epidemiology of SARS-CoV-2 during the early 2020 epidemic of COVID-19 in Europe. To test this hypothesis, we developed a population-based model of SARS-CoV-2 transmission and of COVID-19 mortality, which simultaneously incorporated the impact of non-pharmaceutical control measures and of influenza on the epidemiological dynamics of SARS-CoV-2. Using statistical inference methods based on iterated filtering, we confronted this model with mortality incidence data in four European countries (Belgium, Italy, Norway, and Spain) to systematically test a range of assumptions about the impact of influenza. We found consistent evidence for a 1.8–3.4-fold (uncertainty range across countries: 1.1 to 5.0) average population-level increase in SARS-CoV-2 transmission associated with influenza during the period of co-circulation. These estimates remained robust to a variety of alternative assumptions regarding the epidemiological traits of SARS-CoV-2 and the modeled impact of control measures. Although further confirmatory evidence is required, our results suggest that influenza could facilitate the spread and hamper effective control of SARS-CoV-2. More generally, they highlight the possible role of co-circulating pathogens in the epidemiology of COVID-19.

Background Delirium occurs frequently in critically ill and injured patients and is associated with significant morbidity and mortality. Limited data exists on the risk factors for developing delirium in critically ill trauma patients and the effect of antipsychotic (AP) medications on delirium progression. Objective The objective of this study is to determine the incidence of delirium in critically ill trauma versus non-trauma surgical patients and determine if the presence of trauma was associated with intensive care unit (ICU) delirium. Secondary outcomes included identifying risk factors for delirium and determining the impact of AP medication use on delirium progression in critically ill trauma patients. Methods This retrospective review studies adult trauma/surgical ICU patients admitted between May 2017-July 2018 to a level I trauma and tertiary referral center. Regression modeling was used to determine the impact of AP use on delirium-free days. Results Delirium was more common in critically ill trauma patients versus non-trauma surgical ICU patients [54/157 (34.4%) vs 42/270 (15.6%), P < .001]. Of the 54 trauma patients with delirium, 28 (52%) received an AP medication for delirium treatment and in the multiple linear regression analysis, AP use was significantly associated with fewer delirium-free days ( P = .02). Discussion Higher admission sequential organ failure assessment scores and increased length of stay were significantly associated with delirium onset in critically ill trauma patients. Use of AP medications for delirium treatment in this population had a negative impact on delirium-free days.

Abstract Background.  The purpose of this study was to determine the risk of prosthetic joint infection (PJI) as a complication of routine genitourinary (GU) procedures in patients with total hip arthroplasty (THA) or total knee arthroplasty (TKA) and to study the impact of antibiotic prophylaxis administered prior to these procedures. Methods.  We conducted a prospective, single-center, case-control study between December 1, 2001 and May 31, 2006. Case patients were hospitalized with total hip or knee PJI. Control subjects underwent a THA or TKA and were hospitalized during the same period on the same orthopedic floor without a PJI. Data regarding demographic features and potential risk factors were collected. The outcome measure was the odds ratio (OR) of PJI after GU procedures performed within 2 years of admission. Results.  A total of 339 case patients and 339 control subjects were enrolled in the study. Of these, 52 cases (15%) and 55 controls (16%) had undergone a GU procedure in the preceding 2 years. There was no increased risk of PJI for patients undergoing a GU procedure with or without antibiotic prophylaxis (adjusted OR [aOR] = 1.0, 95% confidence interval [CI] = 0.2–4.5, P = .95 and aOR = 1.0, 95% CI = 0.6–1.7, P = .99, respectively). Results were similar in a subset of patients with a joint age less than 6 months, less than 1 year, or greater than 1 year. Conclusions.  Genitourinary procedures were not risk factors for subsequent PJI. The use of antibiotic prophylaxis before GU procedures did not decrease the risk of subsequent PJI in our study.
