RESUMO

BACKGROUND: Surgical management of congenital heart disease (CHD) has increased worldwide, but healthcare-associated infections (HAIs) can threaten these efforts. AIM: To analyse the incidence of HAI, the impact of preventive interventions, and microbiological profiles in a paediatric cardiovascular surgery programme. METHODS: Cohort study including children aged <12 years with CHD who underwent cardiovascular surgery between 2010 and 2021 in Medellín, Colombia (a middle-income setting). Data were collected from medical and laboratory records and infection control programme databases. Impact of various preventive interventions was assessed using a Poisson model. P < 0.05 was considered statistically significant. FINDINGS: A total of 2512 surgeries were analysed. Incidence of surgical site infection (SSI) was 5.9%, followed by central line-associated bloodstream infection (CLABSI; 4.7%), catheter-associated urinary tract infection (CAUTI; 2.2%), and ventilator-associated pneumonia (VAP; 1.4%). Most of the strategies focused on preventing SSI, resulting in a reduction from 9.5% in 2010 to 3.0% in 2021 (P = 0.030). Antibiotic prophylaxis based on patient weight and continuous infusion had an impact on reducing SSI (RR: 0.56; 95% CI: 0.32-0.99). Vacuum-assisted closure (VAC) in clean wounds reduced 100% of infections. No significant risk reduction was observed for other HAI with the implemented interventions. CONCLUSION: Preventive strategies effectively reduced SSI but no other infections, emphasizing the need for targeted approaches to address a broader spectrum of HAI successfully.

Introduction: Nosocomial infections, acquired after hospital admission, are the most common adverse events threatening patient health, with pneumonia, including that caused by SARS-CoV-2, responsible for over 80% of nosocomial infections. The pandemic declared by the WHO in March 2020 reflects the rapid rise in cases driven by the virus's spread through droplets and aerosols. Nosocomial transmission of SARS-CoV-2 has been observed since the outbreak's onset in Wuhan, posing an additional challenge to patient quality of life. International hospital studies report nosocomial COVID-19 infection rates between 11% and 44%. Objective: Identifying the proportion of nosocomial SARS-CoV-2 infection in Brazil between March 2020 and December 2022.Methodology:This is an analytical, retrospective, cross-sectional study on the proportion of nosocomial SARS-CoV-2 infection in Brazil, using secondary data from the Influenza Epidemiological Surveillance Information System. In this study, the analyzed dependent variable was the proportionof nosocomial SARS-CoV-2 infection. The exploratory independent variables included: age group, gender, comorbidities, and macro-region of residence.Results:The study identified a proportion of nosocomial cases of 2.58%, with a higher proportion in the third year of the pandemic, 2022 (5.5%) in the North region (7.57%), among individuals aged 18-59 years (6.93%). Conclusions: This study on nosocomial cases of COVID-19 in Brazil reveals a proportion of 2.58% between 2020 and 2022, with associations identified regarding region, age, and comorbidities. Differences compared to international studies suggest specific methodological issues. This research is of critical importance, given its national scope and broad coverage, and establishes a solid foundation for future epidemiological studies (AU).

RESUMO

Introduction: Healthcare-associated infections pose a significant challenge, contributing to hospital morbidity and mortality. Objective: To describe the behavior of Healthcare Associated Infections before and during the pandemic reported to a high-complexity health institution in Colombia. Material and Methods: In our retrospective observational study on Healthcare-Associated Infections (HAIs), we analyzed data from all in-patients diagnosed with HAIs between 2018 and 2020. This included clinical, demographic, microbiological, and microbial susceptibility information collected from the Committee on Nosocomial Infections' prospective database. Data from 391 isolates were obtained using Whonet software for antimicrobial resistance surveillance. Results: We found 504 cases of HAIs (2018-2020) with an overall in-hospital infection rate of 2.55/1000 patient-days. The median age for pediatric patients was 5 years, and for adults, 56 years, with 57% male. The leading admission diagnoses were oncologic disease complications (31%). Bacteremia had a 30-day mortality rate of 13%, predominantly catheter-associated (37%). Gram-negative bacilli, notably Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa, represented 58% cases of HAI. Discussion: The critical need for specific interventions and antimicrobial management to control HAIs, especially given the challenges posed by the COVID-19 pandemic, is highlighted. Conclusions: This is the first report on HAIs incidence at a tertiary hospital in Bucaramanga, Santander (Colombia). Bacteremia was predominant; 75% of HAIs patients had comorbidities. Gram-negative bacilli prevailed; a notable rise in ICU respiratory infections occurred during the 2020 COVID-19 pandemic. Resistance to cephalosporins and carbapenems was prevalent.

RESUMO

Lean healthcare visual management has been successfully integrated into infection control programs, leading to lower healthcare-associated infection (HAI) rates and greater provider compliance with evidence-based prevention practices; however, its implementation during quality improvement (QI) initiatives in limited-resource settings has not yet been well exploited. We aimed to describe a low-cost strategy involving Kamishibai cards to sustain bundles' adherence to prevent HAIs in a middle-income country. This descriptive case study evaluated the implementation of a lean healthcare visual management tool-Kamishibai board (K-board)-during a nationwide QI collaborative preventing three critical HAIs in 189 adult and pediatric/neonatal intensive care units (ICUs) from September 2021 to January 2023. Considering a limited-resource setting, our team adapted a K-board using simple, cheap, and easy-to-handle materials for routine monitoring of QI procedures, including safety bundles' compliance. After test prototypes, the final K-board version was implemented. The chart materials and assembly cost BRL 80.00 (USD 15.48). Before launching, expert working group meetings were held to shape the contents, refine technical issues, and prepare the ICU teams for implementation. After starting, plan-do-study-act cycles were conducted according to the Breakthrough Series model. Participating ICU teams, including leaders and front-line health workers, performed bedside audits following a weekly chronogram. Two indicators were calculated: the percentage of ICUs in which K-boards were being implemented and whether bundles' compliance was addressed in the K-board. Audit data were recorded in 'SimpleQI'. After 17 months of this initiative, 177 (93.7%) participating ICUs had included this visual management tool in their daily care routines. When more than 94 (>50%) ICUs posted K-board data, the mean compliance for the bundles for each HAI was sustained above 85%. A lean healthcare visual management tool can be adapted to local settings, including healthcare facilities with limited resources. K-board seems to be a feasible method for auditing evidence-based practices in medical care, including safety bundles to simultaneously prevent three types of HAIs.

RESUMO

BACKGROUND: Public health officials are responding to an outbreak of fungal meningitis among patients who received procedures under epidural anesthesia at two clinics (River Side Surgical Center and Clinica K-3) in Matamoros, Mexico, during January 1-May 13, 2023. This report describes outbreak epidemiology and outlines interim diagnostic and treatment recommendations. METHODS: Interim recommendations for diagnosis and management were developed by the Mycoses Study Group Research Education and Consortium (MSGERC) based on the clinical experience of clinicians caring for patients during the current outbreak or during previous outbreaks of healthcare-associated fungal meningitis in Durango, Mexico, and the United States. RESULTS: As of July 7, 2023, the situation has evolved into a multistate and multinational fungal meningitis outbreak. A total of 185 residents in 22 U.S. states and jurisdictions have been identified who might be at risk of fungal meningitis because they received epidural anesthesia at the clinics of interest in 2023. Among these patients, 11 suspected, 10 probable, and 10 confirmed U.S. cases have been diagnosed, with severe vascular complications and eight deaths occurring. Fusarium solani species complex has been identified as the causative agent, with antifungal susceptibility testing of a single isolate demonstrating poor in vitro activity for most available antifungals. Currently, triple therapy with intravenous voriconazole, liposomal amphotericin B, and fosmanogepix is recommended. CONCLUSIONS: Efforts to understand the source of this outbreak and optimal treatment approaches are ongoing, but infectious diseases physicians should be aware of available treatment recommendations. New information will be available on CDC's website.

RESUMO

During the COVID-19 pandemic outbreak, COVID-19 healthcare-associated infections (HAI) and risk management became major challenges facing hospitals. Using evidence from a research project, this commentary presents: 1) various communication and information strategies implemented by four hospitals and their staff in Brazil, Canada and France to reduce the risks of COVID-19 HAIs, and how they were perceived by hospital staff; 2) the flaws in communication in the hospitals; and 3) a proposed agenda for research on and action to improve institutional communications for future pandemics. By analyzing "top-down" strategies at the organizational level and spontaneous strategies initiated by and between professionals, this study shows that during the first waves of the pandemic, reliable information and clear communication about guidelines and health protocols' changes can help alleviate fears among staff and avoid misapplication of protocols, thereby reducing infection risks. There was a lack of a "bottom-up" communication channel, while, when making decisions, it is crucial to listen to and fully take into account staff's voices, experiences, and feelings. More balanced communication between hospital administrators and staff could strengthen team cohesion and lead to better enforcement of protocols, which in turn will reduce the risk of contamination, alleviate the potential impacts on staff health, and improve the quality of care provided to patients.

RESUMO

Global dispersion, hospital outbreaks, and lineage relationships between emerging antibiotic-resistant strains such as Klebsiella pneumoniae are of public health interest. This study aimed to isolate and identify K. pneumoniae clones from third-level healthcare hospitals in Mexico to establish their multidrug-resistant phenotype, phylogeny, and prevalence. Biological and abiotic surface samples were used to isolate K. pneumoniae strains and to test their antibiotic susceptibility to classify them. The housekeeping genes: gapA, InfB, mdh, pgi, phoE, ropB, and tonB were used for multilocus sequence typing (MLST). Phylogenetic networks were constructed with 48 strains. Isolated strains (93) were mainly from urine and blood, 96% were resistant to ampicillin as expected, 60% were extended-spectrum ß-lactamases (ESBL), 98% were susceptible to ertapenem and meropenem and 99% were susceptible to imipenem, 46% were multi-drug resistant (MDR), 17% were extensively-drug resistant (XDR), 1% were pan-drug resistant (PDR), and 36% were not classified. The tonB, mdh, and phoE genes were the most variable, and the InfB gene showed positive selection. The most prevalent sequence types (STs) were ST551 (six clones), ST405 (six clones), ST1088 (four clones), ST25 (four clones), ST392 (three clones), and ST36 (two clones). ST706 was PDR, and ST1088 clones were MDR; neither of these STs has been reported in Mexico. The strains analyzed were from different hospitals and locations; thus, it is important to maintain antibiotic surveillance and avoid clone dissemination to prevent outbreaks, adaptation to antibiotics, and the transmission of antibiotic resistance.

RESUMO

Background: Non-HACEK Gram-negative bacilli (NGNB) infective endocarditis (IE) has a growing frequency. We aimed to describe cases of NGNB IE and find associated risk factors. Methods: We conducted a prospective observational study of consecutive patients with definitive IE according to the modified Duke criteria in four institutions in Brazil. Results: Of 1154 adult patients enrolled, 38 (3.29%) had IE due to NGNB. Median age was 57 years, males predominated, accounting for 25/38 (65.8%). Most common etiologies were Pseudomonas aeruginosa and Klebsiella spp. (8 episodes, 21% each). Worsening heart failure occurred in 18/38 (47.4%). Higher prevalence of embolic events was found (55,3%), mostly to the central nervous system 7/38 (18.4%). Vegetations were most commonly on aortic valves 17/38 (44.7%). Recent healthcare exposure was found in 52.6% and a central venous catheter (CVC) in 13/38 (34.2%). Overall mortality was 19/38 (50%). Indwelling CVC (OR 5.93; 95% CI, 1.29 to 27.3; p = 0.017), hemodialysis (OR 16.2; 95% CI, 1.78 to 147; p = 0.008) and chronic kidney disease (OR 4.8; 95% IC, 1.2 to 19.1, p = 0.049) were identified as risk factors for mortality. Conclusions: The rate of IE due to NGNB was similar to that in previous studies. Enterobacterales and P. aeruginosa were the most common etiologies. NGNB IE was associated with central venous catheters, prosthetic valves, intracardiac devices and hemodialysis and had a high mortality rate.

RESUMO

BACKGROUND: Health care-associated infections (HAIs) are a common cause of morbidity and mortality. There is little information on the risk factors associated with HAI in surgical newborns. OBJECTIVE: To identify the risk factors associated with healthcare-associated infections in surgical newborns. METHODS: Nested case-control study carried out during 2016-2017. Cases were newborns with healthcare-associated infections and controls were newborns without infection. Perinatal characteristics, use of antimicrobial prophylaxis, use of central venous catheter (CVC), mechanical ventilation, parenteral nutrition, age, and weight at the time of surgery, type of surgery, surgical wound classification, duration of surgery, number of surgical procedures, postsurgical HAIs and type of infection were registered. Univariate and multivariate analyses were performed. RESULTS: Seventy-one cases and 142 controls were included. The most frequent HAI was bloodstream infection (36.6%); the main microorganisms isolated in blood cultures were gram-positive cocci. Independent risk factors associated with HAIs in the multivariate analysis were CVC duration > 8 days (aOR = 17.2, 95% CI = 3.8-49.1), ≥ 2 surgeries (aOR = 16.5, 95% CI 5.8 -42.1) and abdominal surgery (aOR = 2.6, 95% CI = 1.2-6.6). CONCLUSION: Newborns undergoing surgery, mainly those with risk factors, require close monitoring during the postoperative period. CVC should be withdrawn as soon as possible.

ANTECEDENTES: Las infecciones asociadas a la atención de la salud (IAAS) son causa frecuente de morbilidad y mortalidad. OBJETIVO: Identificar los factores de riesgo para el desarrollo de IAAS en recién nacidos (RN) sometidos a cirugía. MATERIAL Y MÉTODOS: Estudio de casos y controles anidado en una cohorte. Los casos fueron RN sometidos a cirugía, con IAAS y los controles, RN sometidos a cirugía sin IAAS. Se registraron datos perinatales, uso de profilaxis antimicrobiana, de catéter venoso central (CVC), ventilación mecánica, nutrición parenteral y sondas; edad y peso al momento de la cirugía, tipo de cirugía, clasificación de la herida quirúrgica, duración de la cirugía, número de procedimientos quirúrgicos y tipo de infección. Se realizó análisis univariado y multivariado. RESULTADOS: Se incluyeron 71 casos y 142 controles. Las IAAS más frecuentes fueron las infecciones sanguíneas (36.6 %); los principales microorganismos aislados en hemocultivos fueron cocos grampositivos. Los factores de riesgo asociados a IAAS en el análisis multivariado fueron duración del CVC > 8 días (RMa = 17.2), ≥ 2 intervenciones quirúrgicas (RMa = 16.5) y cirugía abdominal (RMa = 2.6). CONCLUSIONES: Los RN sometidos a cirugía, principalmente aquellos con factores de riesgo, requieren vigilancia estrecha durante el posoperatorio. El CVC debe ser retirado tan pronto sea posible.

RESUMO

Background: Although there are simple and low-cost measures to prevent healthcare-associated infections (HAIs), they remain a major public health problem. Quality issues and a lack of knowledge about HAI control among healthcare professionals may contribute to this scenario. In this study, our aim is to present the implementation of a project to prevent HAIs in intensive care units (ICUs) using the quality improvement (QI) collaborative model Breakthrough Series (BTS). Methods: A QI report was conducted to assess the results of a national project in Brazil between January 2018 and February 2020. A 1-year preintervention analysis was conducted to determine the incidence density baseline of the 3 main HAIs: central line-associated bloodstream infections (CLABSIs), ventilation-associated pneumonia (VAP), and catheter-associated urinary tract infections (CA-UTIs). The BTS methodology was applied during the intervention period to coach and empower healthcare professionals providing evidence-based, structured, systematic, and auditable methodologies and QI tools to improve patients' care outcomes. Results: A total of 116 ICUs were included in this study. The 3 HAIs showed a significant decrease of 43.5%, 52.1%, and 65.8% for CLABSI, VAP, and CA-UTI, respectively. A total of 5140 infections were prevented. Adherence to bundles inversely correlated with the HAI incidence densities: CLABSI insertion and maintenance bundle (R = -0.50, P = .010 and R = -0.85, P < .001, respectively), VAP prevention bundle (R = -0.69, P < .001), and CA-UTI insertion and maintenance bundle (R = -0.82, P < .001 and R = -0.54, P = .004, respectively). Conclusions: Descriptive data from the evaluation of this project show that the BTS methodology is a feasible and promising approach to preventing HAIs in critical care settings.

RESUMO

Introduction. Healthcare-associated infections (HAIs) are the most recurrent adverse event in hospitals worldwide and represent an important public health problem.Gap statement. There are a paucity of multicentric data describing severe HAIs such as bloodstream infection (BSI) and pneumonia in Brazil.Aim. To provide an up-to-date picture of the extent and patterns of HAIs in adult intensive care units (ICUs), as well as to identify variables associated with the risk of development of severe infections.Methodology. Point prevalence surveys were conducted using standardized protocols in 35 ICUs from Minas Gerais state, Brazil. Medical records of eligible inpatients at or before 8 am on the survey day were reviewed to identify HAIs present at the time of the survey. A matched-pairs case-control study was performed on a total of 66 pairs for BSI and 115 pairs for pneumonia according to the selection criteria developed.Results. Overall, 171 patients (45.7%) had at least one HAI, with most (78.4%) acquired in the ICU. These patients presented a total of 240 infections; including 123 pneumonia (51.3%) and 66 BSI (27.5%), and 78.9 and 80.3 %, respectively, were acquired in the ICU. Their aetiology showed a predominance of Gram-negative bacteria versus Gram-positive bacteria (48.9 versus 43.3 %), with Acinetobacter baumannii (13.7%) and Pseudomonas aeruginosa (12.8%) being prominent. One striking observation from our data was the higher prevalence of Staphylococcus aureus (14.5%) and coagulase-negative staphylococci (10.2%) observed in the overall HAIs.Conclusion. A high severe ICU-acquired HAI burden was found when compared with findings from other low- and middle-income countries. These data can be utilized for better planning of nosocomial infection surveillance programmes in our hospitals.

RESUMO

The gut microbiota harbors diverse bacteria considered reservoirs for antimicrobial resistance genes. The global emergence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacterales (ESBL-PE) significantly contributes to healthcare-associated infections (HAIs). We investigated the presence of ESBL-producing Escherichia coli (ESBL-PEco) and ESBL-producing Klebsiella pneumoniae (ESBL-PKpn) in neonatal patients' guts. Furthermore, we identified the factors contributing to the transition towards ESBL-PEco and ESBL-PKpn-associated healthcare-associated infections (HAIs). The study was conducted from August 2019 to February 2020, in a Neonatal Intensive Care Unit of the Hospital Infantil de México Federico Gómez. Rectal samples were obtained upon admission, on a weekly basis for a month, and then biweekly until discharge from the neonatology ward. Clinical data, culture results, and infection information were gathered. We conducted antimicrobial tests, multiplex PCR assay, and pulsed-field gel electrophoresis (PFGE) to determine the antimicrobial resistance profile and genetic relationships. A comparison between the group's controls and cases was performed using the Wilcoxon and Student t-tests. Of the 61 patients enrolled, 47 were included, and 203 rectal samples were collected, identifying 242 isolates. In 41/47 (87%) patients, colonization was due to ESBL-PEco or ESBL-PKpn. And nine of them developed HAIs (22%, 9/41). ESBL-PEco resistance to cephalosporins ranged from 25.4% to 100%, while ESBL-PKpn resistance varied from 3% to 99%, and both bacteria were susceptible to carbapenems, tigecillin, and colistin. The prevalent bla CTX-M-group-1 gene accounted for 77.2% in ESBL-PEco and 82.2% in ESBL-PKpn, followed by bla TEM 50% and bla OXA-1 43.8% in ESBL-PEco and bla TEM 80.2% and bla SHV 76.2% in ESBL-PKpn. Analysis of clonality revealed identical colonizing and infection isolates in only seven patients. Significant risk factors included hospital stay duration, duration of antibiotic treatment, and invasive device usage. Our findings suggest high ESBL-PEco and ESBL-PKpn rates of colonization often lead to infection in neonates. Attention should be paid to patients with ESBL-PE.

RESUMO

SUMMARY INTRODUCTION: Patients hospitalized for treatment may be exposed to healthcare-associated infections, and these infections can affect patients seriously. OBJECTIVE: This research was conducted to determine what hospitalized patients know and what they want to know about healthcare-associated infections. METHODS: This is a full-text original research article. The study was conducted between July and September 2022 with inpatients in all clinics of Kocaeli University Hospital in Turkey. A total of 310 patients participated in this cross-sectional study. The questions were asked by the researcher and the answers were recorded. RESULTS: Almost all (92.8%) the patients who stated that they knew what healthcare-associated infection was evaluated their knowledge as insufficient. Patients with higher educational levels have more information (p=0.000) about healthcare-associated infections. Young (p=0.000) and highly educated patients (p=0.000) stated that the infection rate of the hospital would affect the choice of hospital. CONCLUSION: Patients want to learn about healthcare-associated infections, but most do not know about them. Patients should be informed about healthcare-associated infections during hospitalization planning and hospitalization.

RESUMO

Background: In intensive care units (ICUs), infections by multidrug-resistant (MDR) microorganisms should be monitored to prevent healthcare-associated infections (HAIs). Methods: From 2018 to 2020, we investigated all medical records of patients admitted to the ICU of a public university hospital. All patients colonized/infected by MDR microorganisms and submitted to active surveillance cultures (ASCs) were included. Results and discussion: Male patients prevailed, and 9.5% were positive for MDR bacteria. In-hospital deaths were statistically significant (p < 0.05) for older patients, patients with orotracheal tube use during previous and current hospitalization, and patients with high blood pressure, cardiac and pulmonary diseases, and chronic kidney disease. Carbapenem resistant Enterobacteriaceae was the most frequently resistance profile, followed by extended-spectrum beta-lactamase. The diagnosis or evolution of HAIs was statistically significant (p < 0.0001) for patients treated with meropenem and vancomycin, and in-hospital deaths occurred in 29.5% of patients using polypeptides while the use of macrolides reduced the odds for mortality. The BRADEN Scale demonstrated that 50% of the patients were at high risk of dying. Conclusion: Patients hospitalized in the ICU, colonized or infected by MDR bacteria, using invasive medical devices, and with underlying medical conditions presented increased mortality rates. The prescription of meropenem and vancomycin should be carefully monitored once patients using these antimicrobials already have or develop an HAI.

RESUMO

Introducción: Las infecciones asociadas con la asistencia sanitaria representan un grave problema de salud e impacto económico, elementos que conducen a un aumento en el número de días estancia, agrava el pronóstico del paciente grave y condiciona costo familiar y social. Objetivo: Determinar los principales factores de riesgo asociados a las infecciones relacionadas con la atención médica en la unidad de cuidados intensivos. Métodos: Estudio observacional, analítico, tipo casos y controles en la sala de cuidados intensivos del Hospital Pediátrico Universitario "Paquito González Cueto" en pacientes con infecciones relacionadas con los servicios sanitarios, desde enero 2018 a diciembre 2020. Resultados: Predominaron los menores de 4 años fundamentalmente el grupo de 1-4 años con riesgo 2,1 veces mayor para las infecciones con ligero predominio del sexo masculino, prevalecieron los normopesos 31,6 % que presentaron algún déficit nutricional por defecto, con un riesgo de infección de 7,2 veces para desnutridos; 48,3 % de los pacientes tenían un factor intrínseco asociado. Las enfermedades neurológicas crónicas, oncoproliferativas e inmunodeficiencias fueron las más representativas; el uso previo de antibióticos, cateterismo y estadía hospitalaria prolongada fueron los factores extrínsecos que predominaron, con riesgo significativo en casi la totalidad de los pacientes. Conclusiones: Existe asociación con riesgo elevado de infección en niños menores de 4 años, con déficit nutricional por defecto; factores intrínsecos como las enfermedades crónicas con predominio de las neurológicas y factores de riesgo extrínsecos significativos en su mayoría. Esto permite dirigir las estrategias de mejora para disminuir la morbilidad y mortalidad.

Introduction: Infections associated with healthcare represent a serious health problem and an economic impact, elements that lead to an increase in the number of days/stay, worsen the prognosis of the seriously ill patient and conditions family and social cost. Objective: To determine the main risk factors associated with healthcare-related infections in the intensive care unit. Methods: Observational, analytical, case-control type study in the intensive care unit of "Paquito González Cueto" University Pediatric Hospital in patients with infections related to health services, from January 2018 to December 2020. Results: Children under 4 years of age predominated, mainly the group of 1-4 years with a 2.1 times higher risk for infections, with a slight predominance of the male sex, the normal weight prevailed (31.6%) who presented some nutritional deficit by default, with a risk of infection of 7.2 times for malnourished; 48.3% of the patients had an associated intrinsic factor. Chronic neurological, onco-proliferative and immunodeficiencies diseases were the most representative; the previous use of antibiotics, catheterization and prolonged hospital stay were the extrinsic factors that predominated, with significant risk in almost all patients. Conclusions: There is an association with an elevated risk of infection in children under 4 years of age, with nutritional deficit by default; intrinsic factors such as chronic diseases with a predominance of neurological diseases and significant extrinsic risk factors. This makes it possible to direct improvement strategies to reduce morbidity and mortality.

RESUMO

Healthcare-associated infections (HAIs) represent a global challenge and an even more staggering concern when related to microorganisms capable of resisting and surviving for long periods in the environment, such as Acinetobacter spp. Strategies that allow a reduction of pathogens from hospital environments represent an additional barrier in infection control protocols, minimizing transmission to hospitalized patients. Considering the antimicrobial properties of copper, here, the bacterial load and the presence of Acinetobacter spp. were monitored on high handling surfaces covered by 99.9% copper films on intensive and non-intensive care unit bedrooms in a tertiary care hospital. Firstly, copper-coated films were able to inhibit the adhesion and biofilm formation of A. baumannii strains in in vitro assays. On the other hand, Acinetobacter spp. were isolated from both copper-coated and uncoated surfaces in the hospital, although the majority was detected on surfaces without copper. All carbapenem-resistant A. baumannii isolates identified harbored the blaoxa-23 gene, while the A. nosocomialis isolates were susceptible to most antimicrobials tested. All isolates were susceptible to polymyxin B. Regarding the total aerobic bacteria, surfaces with copper-coated films presented lower total loads than those detected for controls. Copper coating films may be a workable strategy to mitigate HAIs, given their potential in reducing bacterial loads in nosocomial environments, including threatening pathogens like A. baumannii.

RESUMO

INTRODUCCIÓN: La pandemia por coronavirus se diseminó mundialmente con una amplia variedad de presentaciones clínicas. Se reportó que 15% de los pacientes requirió internación en una unidad de cuidados intensivos (UCI). Estudios epidemiológicos demostraron que pacientes con ventilación mecánica invasiva (VMi) por SARS-Cov-2 presentan más riesgo de infecciones asociadas a la atención de la salud (IAAS). OBJETIVO: Describir la incidencia IAAS en adultos internados en UCI en VMi del Sanatorio Anchorena San Martín, durante la pandemia en 2020. PACIENTES Y MÉTODOS: Estudio de cohorte retrospectivo, el análisis de normalidad se efectuó mediante test Shapiro-Wilk. El análisis de regresión múltiple se realizó en forma automática, (backward selection). Para la comparación entre grupo COVID-19 y no COVID-19 se utilizó T test o Test de Wilcoxon según correspondiera; y el χ2 o el test exacto de Fisher. Todas las estimaciones de las funciones de incidencia acumuladas fueron realizadas con el paquete cmprsk. RESULTADOS: Se incluyeron 252 pacientes, 40 desarrollaron IAAS (incidencia acumulada de 15,9%), con un total de 60 eventos de IAAS. La edad (OR 0,96), cantidad de accesos venosos centrales (AVC) (OR 2,01), COVID-19 (OR 2,96) y decúbito prono (OR 2,78) se asociaron a IAAS. Desarrollar IAAS se asoció a más días de VMi y estadía en UCI. La incidencia acumulada de IAAS en pacientes NO COVID fue menor que en COVID-19. Días de VMi y mortalidad en UCI fueron mayores en pacientes con COVID. El 29,6% de los pacientes con COVID-19 desarrolló algún tipo de IAAS vs 7,1% en NO COVID. CONCLUSIÓN: Describimos la incidencia de IAAS en nuestra cohorte. La presencia de COVID-19, AVC, el decúbito prono y estadía en UCI se asociaron con mayor probabilidad de contraer una IAAS.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has spread fast globally comprising a great variety of clinical presentations. It was reported that 15% of patients required admission to intensive care units (ICU). Previous epidemiological studies have reported higher risk of healthcare-associated infections (HCAI) in those patients requiring invasive mechanical ventilation (iMV) due to COVID-19. AIM: To analyze the incidence of HCAI in adults under iMV admitted to ICU of Anchorena San Martín Clinic during COVID-19 pandemic. METHODS: Retrospective cohort study, the analysis of normality was carried out using the Shapiro-Wilk test. The multiple regression analysis was performed automatically, based on backward elimination of the variables (backward selection). For the comparison between the COVID-19 and non-COVID-19 groups, the T test or Wilcoxon test was used, as appropriate; and the χ2 or Fisher's exact test. All cumulative incidence function estimates were made with the cmprsk package. RESULTS: 252 patients were included, 40 patients developed HCAI (accumulated incidence was 15.9%), counting for 60 total HCAI events. Age (OR 0.96), number of central venous access devices (CVAD) (OR 2.01), COVID-19 (OR 2.96) and prone positioning (OR 2.78) were associated with HCAI. HCAI was associated with more days of iMV and ICU stay. The accumulated incidence of HCAI in non-COVID-19 patients was lower than in COVID-19 patients. iMV days and mortality were higher in COVID-19. 29.6% of COVID-19 patients developed HCAIs vs 7.1% of non-COVID-19 ones. CONCLUSION: We describe the incidence of HCAI. Age, COVID-19, CVAD, prone positioning and ICU stay were associated with higher probability of HCAIs.

RESUMO

Resumen La infección por Clostridioides difficile (ICD) puede variar desde diarrea hasta megacolon tóxico. Los objetivos del trabajo fueron mostrar la variación en el número de casos diagnosticados de ICD en este laboratorio entre 2020, cuando comenzó la pandemia de COVID-19 y 2019 y 2021 y detallar los casos precedidos por la infección de SARS-CoV-2. El presente es un estudio retrospectivo observacional en el que se registraron el número total de muestras procesadas con sospecha de ICD y el de positivas y los antecedentes clínicos de pacientes con ICD hasta dos meses después de su diagnóstico de COVID-19. Durante 2020 se procesaron menos muestras que en 2019 y 2021; sin embargo, el porcentaje de positividad fue de 13,1%, 7,2% y 7,8%, respectivamente. Esto pudo deberse a mejoras en el criterio clínico al momento de seleccionar las muestras con sospecha de ICD.

Abstract Clostridioides difficile infection (CDI) can cause anything from diarrhea to toxic megacolon. The objectives of this study were: to show the variation in the number of diagnosed cases of CDI in this center, comparing 2020, when the COVID-19 pandemic began, with 2019 and 2021 and to detail cases preceded by SARS-CoV-2 infection. This is an observational retrospective study in which the total number of samples processed with suspected CDI were recorded. The positive ones and the clinical history of patients with a diagnosis of CDI up to two months after their diagnosis of SARS-CoV-2 infection were recorded as well. During 2020 a smaller number of samples were processed. However, during this year the percentage of positivity was 13.1% vs. 7,2% and 7.8% during 2019 and 2021, respectively. It is believed that this may have been due to improvements in clinical suspicion and sample selection for CDI diagnosis.

Resumo A infecção por Clostridioides difficile (ICD) pode causar desde diarreia até megacólon tóxico. Os objetivos desta apresentação foram: mostrar a variação do número de casos diagnosticados de ICD neste laboratório, entre 2020 quando começou a pandemia de COVID-19 e 2019 e 2021 e, detalhar os casos precedidos pela infecção por SARS-CoV-2. Esse estudo foi retrospectivo observacional e foram registrados: o número total de amostras processadas com suspeita de ICD e de amostras positivas e os antecedentes clínicos daqueles pacientes com diagnóstico de ICD até dois meses após o diagnóstico de COVID 19. Durante 2020, foram processadas menos amostras do que em 2019 e 2021; no entanto, o percentual de positividade foi de 13,1%, 7,2% e 7,8%, respectivamente. Isso pode ter sido resultado de melhorias no critério clínico na hora de selecionar as amostras com suspeita de ICD.

RESUMO

OBJECTIVES: Consumption trends of four broad-spectrum antimicrobials and their correlation with antimicrobial resistance in Gram-negative bacilli (GNB) from 2013-2017 within intensive care units (ICUs) were explored. METHODS: Consumption of meropenem (MEM), polymyxin B (PMB), piperacillin/tazobactam (TZP) and cefepime (FEP) in defined daily doses per 1000 patient-days (DDD/1000PD) was measured. Infection-related GNB isolates were grouped according to specific resistance profiles. Time series of antimicrobial consumption and their parametric correlation with each grouped resistant GNB were explored. RESULTS: A total of 1423 GNB were evaluated. A significant linear decline in consumption was observed for MEM [slope -3.88, 95% confidence interval (CI) -4.96 to -2.81; P < 0.0001] and PMB (slope -3.51, 95% CI -5.528 to -1.495; P = 0.0009). A significant decline in MEM-non-susceptible Acinetobacter spp. (R2 = 0.476; P = 0.006) and an increase in FEP-non-susceptible Escherichia coli (R2 = 0.124; P = 0.006) was observed. A significant correlation between MEM consumption and MEM-non-susceptible Acinetobacter spp. (r = 0.43; P = 0.001) was observed. MEM consumption and MEM-non-susceptible Acinetobacter spp. showed a positive correlation. CONCLUSION: Reduction in the consumption of broad-spectrum antimicrobials may alter the frequency of infection-related isolates and their antimicrobial resistance profiles.
