Clinical analysis of different types of neonatal sepsis: a multi-center retrospective study / 中国新生儿科杂志

Objective:To study the clinical characteristics of different types of neonatal sepsis.Methods:From January 2012 to December 2019, neonates with confirmed sepsis from 5 neonatal centers of central-south China were reviewed. The neonates were assigned into early-onset sepsis (EOS) and late-onset sepsis (LOS) group, and the latter was further subgrouped into hospital-acquired LOS (hLOS) group and community-acquired LOS (cLOS) group. The etiological and clinical characteristics were analyzed. SPSS 26.0 was used for statistical analysis.Results:A total of 580 neonates were enrolled, including 286 (49.3%) in the EOS group and 294 (50.7%) in the LOS group. In LOS group, 147 were in hLOS group and 147 were in cLOS group. The gestational age and birth weight of hLOS group were significantly lower than the other two groups [(32.7±3.6) weeks vs. (37.1±3.7) weeks and (37.7±3.0) weeks, (1 810±717) g vs. (2 837±865) g and (3 024±710) g] ( P<0.05). The common pathogens in EOS and cLOS groups were coagulase-negative staphylococci and Escherichia coli, while Klebsiella pneumoniae was common in hLOS group. Carbapenems usage in the hLOS group was significantly higher than the other two groups [62.6% vs. 28.7% and 16.2%] ( P<0.05). Antibiotics duration in the hLOS group was longer than the other two groups [19 (14, 27) d vs. 15 (12, 20) d and 14 (12, 19) d] ( P<0.05). Conclusions:The clinical characteristics of neonatal sepsis vary among different types of infections, and it is necessary to establish appropriate prevention, control, diagnosis and treatment protocols.

Bed bath protocol for infection reduction: a quasi-experimental study / Protocolo de higiene de pacientes en la cama para reducir infecciones: estudio cuasiexperimental / Protocolo de banho no leito para redução de infecções: estudo quase experimental

ABSTRACT Objective: To analyze the effect of implementing a bed bath protocol in relation to infection-free time and the prevalence of Healthcare-Associated Infections. Method: A quasi-experimental study with a comparison between two groups. In the Control Group, the data were retrospectively collected between January and April 2018. Implementation of the bed bath protocol in an Intensive Care Unit took place from May to October 2018. Data from the Intervention Group were collected from November 2018 to February 2019 through daily follow-up during the hospitalization period. Results: There were 157 participants in the Control Group and 169 in the Intervention Group, with a mean age of 56 and 54 years old, respectively, and majority of male individuals. The occurrence of Healthcare-Associated Infections was higher in the Control Group (n=32; 20.4%) compared to the Intervention Group (n=10; 5.9%), which presented a 2.86 times lower risk of developing Healthcare-Associated Infections (p<0.01). The Intervention Group presented a longer infection-free time when compared to the Control Group, which had a mean of 2.46 times higher risk of developing infections in the Intensive Care Unit (95%CI: 1.18; 5.11). Conclusion: The study provides support for standardizing the bed bath technique and to preventing health-care associated infections. There is a limitation in generalization of the results, as the groups come from a quasi-experimental before-after design with a non-equivalent Control Group due to the absence of random distribution in the compared groups.

RESUMEN Objetivo: analizar el efecto de implementar un protocolo de higiene de pacientes en la cama en relación con el tiempo sin infección y la prevalencia de Infecciones Relacionadas con la Atención de la Salud. Método: estudio cuasi experimental con comparación entre dos grupos. En el Grupo Control, los datos se recolectaron retrospectivamente entre enero y abril de 2018. La implementación del protocolo de higiene de pacientes en la cama de una Unidad de Cuidados Intensivos tuvo lugar entre mayo y octubre de 2018. Los datos del Grupo Intervención se recolectaron entre noviembre de 2018 y febrero de 2019 por medio del seguimiento diario durante el período de internación. Resultados: hubo 157 participantes en el Grupo Control y 169 en el Grupo Intervención, con una media de edad de 56 y 54 años, respectivamente, y la mayoría del sexo masculino. La incidencia de Infecciones Relacionadas a la Atención de la Salud fue mayor en el Grupo Control (n=32; 20,4%) que en el Grupo Intervención (n=10; 5,9%), y este último presentó 2,86 veces menos riesgo de desarrollar Infecciones Relacionadas a la Atención de la Salud (p<0,01). El Grupo Intervención presentó mayor tiempo sin infección en comparación con el Grupo Control, cuyos participantes tuvieron un promedio de 2,46 veces mayor riesgo de desarrollar infecciones en la Unidad de Cuidados Intensivos (IC95%: 1,18; 5,11). Conclusión: el estudio ofrece aportes para estandarizar la técnica de higiene de pacientes en la cama y prevenir infecciones relacionadas con la atención de la salud. Existe cierta limitación en cuanto a la generalización de los resultados, puesto que los grupos provienen de un diseño cuasiexperimental del tipo "antes-después" con un Grupo Control no equivalente, debido a la ausencia de distribución aleatoria en los grupos comparados.

Comparative assessment of infection prevention and control practice among maternity unit health workers in public and private secondary health facilities in Kaduna state, Nigeria

OBJECTIVES: Infection prevention and control (IPC) practice in health facility (HF) is abysmally low in developing countries, resulting in significant preventable morbidity and mortality. This study assessed and compared health workers' (HWs) practice of IPC strategies in public and private secondary HFs in Kaduna State. MATERIAL AND METHODS: A cross-sectional comparative study was employed. Using multistage sampling, 227 participants each were selected comprising of doctors, midwives, and nurses from public and private HF. Data were collected using interviewer-administered questionnaire and observation checklist and analyzed using bivariate and multivariate analysis. Statistical significance determined at P < 0.05. RESULTS: The practice of infection prevention was poor. Overall, 42.3% of the HWs did not change their gowns in-between patients, with the significantly higher rates in 73.1% of private compared to 42.3% of public HF workers (P < 0.001). In addition, 30.5% and 10.1% of HWs do not use face mask and eye goggle, respectively, when conducting procedures likely to generate splash of body fluids, however, there was no significant difference in these poor practices in public compared to private HFs. The mean IPC practice was 51.6 ± 12.5%, this was significantly lower among public (48.8 ± 12.5%) compared to private (54.5 ± 11.9%) HF workers (P < 0.0001). Private HF workers were 3 times more likely to implement IPC interventions compared to public HF workers. CONCLUSION: IPC practice especially among public HF workers was poor.

Oxigenación por membrana extracorpórea (ECMO): una mirada desde la prevención de Infecciones Asociadas a la Atención en Salud (IAAS) / Extracorporeal membrane oxygenation (ECMO): an infection control perspective

Resumen La aparición de la enfermedad por SARS-CoV-2 el año 2020 nos enfrentó a un aumento creciente y exponencial de pacientes con riesgo vital por falla respiratoria catastrófica y multisistémica que deben ser sometidos a ECMO para sobrevivir. Esto ha generado en nuestro país la aparición de Unidades de Tratamiento (ECMO) en hospitales en que antes no se disponía de este recurso o se realizaba como parte de las intervenciones en Unidades de Cuidados Intensivos (UCI), lo que constituye un nuevo desafío a los programas de control y prevención de infecciones de los centros de salud. Dado que al momento de la redacción de este documento no existe normativa nacional específica que se refiera a este tema, se propone un enfoque para prevención, control y vigilancia de infecciones asociadas a atención de salud en pacientes ECMO. Se presenta una revisión de los riesgos específicos a que están expuestos estos pacientes, definiendo qué medidas de prevención se requieren, proponiendo un conjunto de medidas específicas para instalación y mantención, así como orientación respecto de antibioprofilaxis y se sugiere qué eventos infecciosos vigilar.

Abstract The advent of SARS-CoV-2 disease in 2020 confronts us with a growing and exponential increase in patients at life risk due to catastrophic and multisystemic respiratory failure in need of extracorporeal membrane oxygenation (ECMO) to survive. This has generated in our country the establishment of ECMO treatment Units in hospitals where it was not carried out before or was carried out as part the interventions in Intensive Care Units (ICU), becoming a new challenge to the infection control and prevention programs. Given that at the time of writing this document there are no specific national regulations that refer to this issue, an approach is proposed for the prevention control and surveillance of nosocomial acquired infections in ECMO patients. A review of the specific risks to which these patients are exposed is presented, defining which prevention measures are required, proposing a specific bundle for installation and maintenance, as well as guidance regarding antibioprophylaxis and suggesting which infectious events to monitor.

Knowledge of hand cleanliness among medical students and nurses at tertiary healthcare centre: a cross-sectional study

Background: Hand hygiene is documented as one of the foremost techniques to prevent cross-transmission of germs. Objectives: This paper aims to assess the knowledge of hand cleanliness among medical students and working nurses. Methods: It was a cross-sectional descriptive study, carried over a sample selected by non-probability convenient sampling technique. The questionnaire used here to assess the knowledge and practice on hand hygiene was adapted from the World Health Organization (WHO) Guidelines on Hand Hygiene in Health Care. The data thus collected were presented in terms of counts and percentages. Chi-square test was used to test the significance of the differences, and a p-value of less than 0.05 was considered as statistically significant. Results: Overall, 92.08% of participants have received training in handwashing. Twenty-five (41.60%) medical students believed that the microbes already present with the patient were responsible for hospital-acquired infection (HAI). Medical students had significantly higher knowledge than working nurses regarding dryness of skin due to hand rubbing over handwashing (p<0.05). Medical students also had substantially higher awareness about the performance of handwashing and hand rubbing in sequence (p<0.05), which they think was not right. Knowledge on the colonisation of hands with harmful microbes was more with the nurses. Conclusion: There is a need to increase awareness among medical students and nurses regarding procedural hand hygiene methods to prevent HAI. The current findings can be a basis for conducting a training programme on hand hygiene practices for the medical students, including paramedical staff members.

Infectious complications associated with parenteral nutrition in intensive care unit and non-intensive care unit patients

ABSTRACT Introduction: Malnutrition is associated with an increased risk of complications in hospitalized patients, and parenteral nutrition (PN) is used when oral or enteral feeding is not possible. This study aimed at analyzing associations between PN characteristics and infectious complications in hospitalized patients. Material and methods: This was a retrospective cohort study conducted in a tertiarycare university hospital. Data from consecutive adult patients submitted to PN (January 2016 to December 2017; ICU and ward) were reviewed by means of an electronic database. Patient's clinical characteristics, PN prescription and catheter insertion procedure data were extracted and analyzed. The main outcome was the development of central line-associated bloodstream infection (CLABSI). The secondary outcomes were other infectious complications and mortality, as well as factors associated with CLABSI. Results: We analyzed 165 patients and 247 catheters used for parenteral nutrition infusion. The CLABSI rate was 6.47 per 1000 catheter-days. In the univariable analysis, CLABSI was associated with longer hospitalization time, longer PN time, longer catheter time, catheter insertion performed by a surgeon or a surgical resident, and procedures performed outside the ICU. In an extended time-dependent Cox regression, no variable was associated with a higher risk of CLABSI, and additional PN days did not increase the rate of CLABSI. The overall mortality rate was 24.8%. Only the patients' comorbidity index was associated with death in the multivariable analysis. Discussion: In our study, patients who needed PN had an overall CLABSI rate of 6.47 per 1000 catheter-days. These outcomes were not associated with PN and catheter characteristics studied after adjustment for catheter time. The overall mortality rate was 24.8% and it was not associated with PN in multivariable analyses, only with Charlson comorbidity index.

Early education and clinical exposure on hand hygiene: a key for better compliance

Background: India is underperforming when it comes to compliance to hand hygiene. Early education on followed by regular hand hygiene audits can bring positive changes in infection control practices.Methods: Group I included the 3rd Semester MBBS students who had early education and training on hand hygiene and Group II included the post graduate residents who were exposed to Hand Hygiene later in their carrier were followed up for compliance of WHO Hand Hygiene moments for four months. Compliance among students and residents were observed and compared.Results: Compliance rate was more (40.4%) among medical students as compared to residents (17%). The After moments had a better compliance than Before moments among both students and residents. The difference in the compliance rate was statistically significant.Conclusions: Early clinical exposure of the students to any problem, is the key for better compliance thus explaining the better compliance rate among medical students. Better HH practice can bring down prevalence of Healthcare associated infection by multidrug resistant organism which is a major concern today.

Prevalence and antimicrobial susceptibility profile of microorganisms in a university hospital from Vitória (ES), Brazil / Prevalência de microrganismos e perfil de suscetibilidade antimicrobiana em um hospital universitário de Vitória (ES), Brasil

ABSTRACT INTRODUCTION: Healthcare associated infections (HAIs) occur during the hospital stay as a result of underlying morbidity, invasive procedures, acute pathology or medical treatment. They lead prolonged stay and, consequently, to an increase in financial charges. The main tool to control these infections is the use of antimicrobials. However, the increase in resistance and the low frequency of discovery of new drugs justify the research that evaluates the resistance profile of microorganisms to antimicrobials. OBJECTIVE: To evaluate the prevalence and antimicrobial susceptibility profile of HAIs at a philanthropic reference hospital in Espírito Santo, Brazil. METHODS: Observational, retrospective and cross-sectional study, between July 2014 and June 2016. Data on blood, urine and corporal secretions culture were collected from the data base of the Hospital Infection Control Commission. RESULTS: There was a high prevalence of HAIs in patients older than 60 years. Two hundred and forty three (47.55%) patients were female. The four most prevalent bacteria were: Acinetobacter spp., Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. Polymyxin was the drug which presented the best antimicrobial effects. CONCLUSION: Polymyxin was active in vitro against all isolates of Acinetobacter spp. Regarding K. pneumoniae, both polymyxin and amikacin showed a significant effectiveness. Regarding Pseudomonas aeruginosa, polymyxin was effective in all samples. Regarding S. aureus, teicoplanin, daptomycin and vancomycin were effective in all samples. Polymyxin showed a good overall in vitro activity.

RESUMO INTRODUÇÃO: As infecções relacionadas com a assistência à saúde (IRAS) ocorrem durante a internação como resultado de morbidade subjacente, procedimentos invasivos, patologia aguda ou tratamento médico. Elas levam à prolongada permanência e, consequentemente, à carga econômica. A principal ferramenta para conter essas infecções são os antimicrobianos. No entanto, o aumento da resistência e a baixa taxa de descoberta de novos medicamentos justificam a pesquisa que avalia o perfil de resistência de microrganismos aos antimicrobianos. OBJETIVO: Avaliar a prevalência e o perfil de suscetibilidade antimicrobiana das IRAS ocorridas em um hospital filantrópico de referência do Espírito Santo, Brasil. MÉTODOS: Estudo observacional, retrospectivo e transversal, entre julho de 2014 e junho de 2016. Os dados sobre cultura de sangue, urina e secreções corporais foram coletados da base de dados do Centro de Controle de Infecção Hospitalar. RESULTADOS: Houve alta prevalência de IRAS em pacientes com mais de 60 anos. Duzentos e quarenta e três (47.55%) pacientes eram do sexo feminino. As quatro bactérias mais prevalentes foram: Acinetobacter spp., Klebsiella pneumoniae, Pseudomonas aeruginosa e Staphylococcus aureus. A polimixina foi a droga que apresentou os melhores efeitos antimicrobianos. CONCLUSÃO: A polimixina foi ativa in vitro contra todos os isolados de Acinetobacter spp. Quanto à K. pneumoniae, tanto a polimixina quanto a amicacina apresentaram eficácia significativa. Em relação à Pseudomonas aeruginosa, a polimixina foi efetiva em todas as amostras. Já em relação ao S. aureus, teicoplanina, daptomicina e vancomicina foram efetivas em todas as amostras. A polimixina demonstrou um bom desempenho geral in vitro.

Resistance of non-fermenting Gram-negative bacilli isolated from blood cultures from an emergency hospital / Resistência de bacilos Gram-negativos não fermentadores isolados de hemoculturas de um hospital de emergência

ABSTRACT Introduction: Non-fermenting Gram-negative bacilli (NFGNB) are a heterogeneous group of microorganisms that do not have the ability to ferment carbohydrates as a way to obtain energy. There are more than 120 species classified as pathogenic, among them, Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Burkholderia cepacia. Infections caused by these microorganisms are mostly acquired in the hospital environment, since they are opportunistic pathogens and are among the most important bacteria of greater clinical and epidemiological relevance. Objective: This study evaluated the resistance profile of NFGNB isolated from blood cultures at an emergency hospital in the city of Caruaru, Agreste Pernambuco (PE), Brazil. Methods: The strains present in the blood cultures were isolated on culture media MacConkey and Triple Sugar Iron (TSI) agar. The samples were also submitted to the oxidase test and the polymyxin resistance test, in addition to the Gram staining, to better identify NFGNB bacterial genera. An antibiogram test was carried out to verify the resistance profile. Results: It was found that from 87 (100%) isolated and analyzed strains, 11 (13%) were classified as NFGNB. The genus Acinetobacter sp. was the most frequently found (55%). The Acinetobacter sp. strains were resistant to gentamicin, meropenem, imipenem, amikacin, ciprofloxacin, ceftazidime and ceftriaxone. Conclusion: Screening of resistant NFGNB isolated, as well as greater attention to hospital-acquired infection control practices and epidemiological surveillance systems, in addition to continued care with regard to the targeted use of antibiotics can contribute to successful this battle against infections by these microorganisms.

RESUMO Introdução: Os bacilos Gram-negativos não fermentadores (BGNNF) são um grupo heterogêneo de microrganismos que não possuem a capacidade de fermentar carboidratos como forma de obtenção de energia. Possuem mais de 120 espécies classificadas como patogênicas, destacando-se entre elas Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia e Burkholderia cepacia. As infecções causadas por esses microrganismos são, em sua maioria, adquiridas nos ambientes hospitalares, já que se tratam de patógenos oportunistas, estando entre as bactérias de maior relevância clínica e epidemiológica. Objetivo: Este trabalho avaliou o perfil de resistência dos BGNNF isolados de hemoculturas em um hospital de emergência na cidade de Caruaru, no Agreste Pernambuco (PE), Brasil. Métodos: As cepas presentes nas hemoculturas foram isoladas nos meios de cultura ágar MacConkey e ágar Triple Sugar Iron (TSI). As amostras também foram submetidas ao teste de oxidase e ao teste de resistência a polimixina, além da coloração de Gram, para melhor identificação dos gêneros bacterianos de BGNNF. Foi realizado o antibiograma para verificação do perfil de resistência. Resultados: Verificou-se que das 87 (100%) cepas isoladas e analisadas, 11 (13%) foram classificadas como BGNNF. O gênero Acinetobacter sp. foi o mais frequente (55%). As cepas de Acinetobacter sp. apresentaram-se resistentes a gentamicina, meropenem, imipenem, amicacina, ciprofloxacina, ceftazidima e ceftriaxona. Conclusão: O rastreamento de isolados de BGNNF resistentes, bem como uma maior atenção às práticas de controle de infecção hospitalar e sistemas de vigilância epidemiológica, além do cuidado contínuo em relação ao uso direcionado de antibióticos podem contribuir no combate a infecções por esses microrganismos.

Objective To evaluate hospital acquired infection control using the risk assessment method of hazard vulnerability analysis (HVA). Methods The HVA risk assessment method was used to screen out two hospital-level priority improvement projects in hospital acquired infection management in 2016, and assess the relative risk of the risk factors,for selective intervention according to the"20% -80% principle". 2015 was set as baseline survey, while the first and second half of 2016 as the outcome evaluation stage. The comparison of the count data was performed using the χ2test. Results Baseline survey of hand hygiene found the compliance rate and high-touch surface cleaning pass rate as 64.4% and 57.0% respectively. The first stage of evaluation found the rate as 69.0% and 73.7% respectively, while in the second stage rate was 72.9% and 82.4% respectively. These differences were statistically significant (P<0.001). Baseline survey found the incidence of hospital acquired infection and surgical site infection as 1.26% and 0.29% respectively, while the figures in the stage of evaluation were 1.07% and 0.22% respectively,figures being statistically significant (P<0.05). Conclusions The HVA risk management proves significant for the prevention and control of hospital acquired infection, as it can identify and assess risk factors of hospital acquired infection,for better risk control.

Infección por adenovirus en el Hospital de niños Roberto del Río 2016 / Adenovirus infection at the Roberto del Río children's Hospital 2016

En los meses de invierno, las enfermedades respiratorias representan la primera causa de hospitalización en hospitales pediátricos. La mayoría de estas enfermedades son causadas por virus, dentro de los cuales se encuentra el adenovirus (AdV), el cual puede generar infecciones diseminadas graves, secuelantes e incluso letales y se caracteriza por tener una rápida transmisión entre pacientes, generando brotes intrahospitalarios. Se identificó a 54 pacientes hospitalizados con infección por adenovirus en el periodo de marzo-julio del 2016 con una edad promedio de 18,3 meses, de los cuales 23 casos fueron infecciones asociadas a la atención de salud (IIAS) y 2 tuvieron desenlace fatal. Los casos de IIAS, se asociaron a una mayor tasa de hospitalización prolongada (p= <0.01), ingreso a UPC (p= <0.01) y uso de ventilación mecánica (p= <0.01). No se encontró asociación entre la presencia de antecedentes mórbidos con el desarrollo de IIAS. Las IIAS por adenovirus se asocia a una hospitalización prolongada, ingreso de unidades de alta complejidad y necesidad de uso de ventilación mecánica. Dado que el adenovirus se transmite a través de contactos directo, aerosoles y fómites, las medidas básicas de precaución de contacto y de aislamiento permiten reducir los contagios nosocomiales, recayendo la responsabilidad en todo el equipo de salud a cargo.

Respiratorio deseases are frequent in winter times. being the main cause of hospital admissions. Viral infecciones are the main etiology, and adenovirus infección clould lead to severe disease, with cross infections. We identified 54 patients admitted to the Roberto del Río Childrens hospital in 2016, with a mean age of 18,3 months old; 23 cases where nosocomial infection, and 2 were fatal. Hospital acquired adenovirus infection were associated to long hospital stay (p= <0.01), intensive care admission (p= <0.01) and ventilatory support (p= <0.01). We did not find previous illness conditions. Adenovirus hospital acquired infection is associated with longer hospital stay and dead. Adenovirus is transmitted with direct contact, aerosols and fomites, therefore basic contact precautions are important.

Improving hand hygiene compliance among healthcare workers: an intervention study in a Hospital in Guizhou Province, China

Abstract Objective Hand hygiene (HH) is a critical component for controlling hospital-acquired infection (HAI). The present study was designed to develop an intervention approach to improve compliance with HH among healthcare workers in a hospital setting. Methods The HH intervention study was conducted in Guizhou Provincial People's Hospital, Guiyang, China and organized by its Department of HAI Management. It was an observational, prospective, quasiexperimental (before-after intervention) study. The study was divided into two phases: the baseline phase and the intervention phase. The investigative team included clinical monitoring staff and infection control practitioners who received a series of instructions on HH compliance, monitoring skills, and measurement of the use of HH products. Results Based on 27,852 observations in a 17-month period, the rate of compliance with HH improved from 37.78% at baseline to 75.90% after intervention. Significant improvement in compliance and an increase in consumption of HH products was observed after intervention. The per patient-day consumption of alcohol-based hand rub products and handwash agents increased by 4.75 mL and 4.55 mL, respectively. The consumption of paper towels increased 3.41 sheets per patient-day. During the same period, the prevalence rate of HAI decreased 0.83%. Conclusions This study demonstrates that a significant improvement in compliance with HH can be achieved through a systemic, multidimensional intervention approach involving all categories of healthcare workers in a hospital setting, which may result in a decrease of the HAI rate.

Study of incidence and risk factors of urinary tract infection in catheterized patients admitted at tertiary care hospital, Nizamabad, Telangana State, India

Background: Catheter-associated urinary tract infections (CAUTIs) are the most common hospital acquired infections and a leading cause of morbidity and mortality in hospitalized patients with various life threatening complications. Hence, this study was aimed to determine the incidence, risk factors of CAUTI in a tertiary care hospital so as to find out better preventive measures to reduce the prevalence of CAUTI and their complications so as to reduce the hospital stay and mortality. Materials and methods: Present study included 200 adult patients who received indwelling urethral foley’s catheter and urinary drainage system in various wards in Government General Hospital, Nizamabad from Jan 2015 - May 2016. Patients were diagnosed to have CAUTI according to CDC guidelines to study its incidence and associated risk factors which were analyzed using multi variate analysis. Results: Overall incidence of CAUTI was 59%. The incidence of CAUTI was maximum (70.58%) in the age group of 51-70 years. The incidence of CAUTI was more (69.44%) in females and was directly proportional to the duration of catheterization. The high incidence in the present study reflects the practice of frequent disconnections of urinary closed systems. Multi-variate analysis shows age, duration of catheterization, catheter- tubing disconnections, absence of antibiotic use and renal Md. Yousuf Khan, C. Venkateshwarlu, G. Sreenivas, P. Rahul. Study of incidence and risk factors of urinary tract infection in catheterized patients admitted at tertiary care hospital, Nizamabad, Telangana State, India. IAIM, 2016; 3(8): 83-92. Page 84 insufficiencies as important risk factors for CAUTI. 88.66% of CAUTIs were asymptomatic among 75 clinically evaluable CAUTIs. Conclusion: CAUTI is an important preventable hospital acquired infection seen in all age groups however incidence increases with age, common in both sexes, incidence can be reduced by minimizing the catheter procedures, taking the maximum aseptic precautions, reducing the duration of catheterization and avoiding frequent disconnections, this becomes more significant in patients with underlying renal disease , prophylactic antibiotics prevent CAUTI. As most of the CAUTI are asymptomatic, all catheterized patients should be screened for CAUTI and be treated depending upon antibiotic sensitivity of uropathogens.

Impacto das infecções relacionadas à assistência à saúde em pacientes acometidos por trauma / Impact of health care-related infections in trauma patients

As infecções relacionadas à assistência hospitalar impactam negativamente a saúde de pacientes hospitalizados, e refletem em elevados índices de morbimortalidade. Este estudo epidemiológico descritivo teve como objetivo caracterizar as infecções e avaliar seu impacto na saúde de pacientes acometidos por trauma, em um hospital universitário, no período de um ano. Os resultados mostraram que a prevalência das infecções nos pacientes do estudo foi elevada (15,6%), acometendo principalmente o sexo masculino (80,0%), com idade entre 18 e 40 anos (47,5%), período de internação maior que 15 dias(78,6%), mais frequente no trauma fechado (54,0%) e nas queimaduras (32,5%). Os principais sítios de infecção foram a pneumonia (49,5%) seguida pela infecção do trato urinário (23,8%). A intubação orotraqueal e o cateterismo vesical de longa permanência estiveram significativamente relacionados à maioria das pneumonias (60,3%; p<0,001) e infecções do trato urinário (77,3%; p<0,001), aumentando os riscos para tais infecções em 20 e 6 vezes, respectivamente. A sepse acometeu 44,7% dos pacientes.Ampla gama de microrganismos apresentou resistência aos antimicrobianos, sendo Acinetobacter baumannii (92,7%, p<0,001) e Klebsiella pneumoniae (70,5%, p<0,001) os mais prevalentes. Evoluíram a óbito 28,8% dos pacientes, e 96,8% das mortes relacionavam-se às infecções. A relação das infecções com o óbito foi estatisticamente significativa em pacientes com pneumonia (37,8%, p<0,001) e sepse(54,2%, p<0,001). A relação das infecções com a maioria dos óbitos evidenciou o impacto negativo desta complicação na saúde das vítimas de traumas.

Healthcare associated infections have an impact on the health of hospitalized patients and are reflected inhigh rates of morbidity and mortality. The aim of this descriptive study is to characterize the infections andevaluate their impact on trauma patient health at a University Hospital over a 1-year period. The resultsshowed that the prevalence of infections in trauma patients was elevated (15.6%), affecting mainly males(80.0%), ages between 18 and 30 years (47.5%), more than 15 days hospitalization (78.6%), more frequentin blunt trauma (54.0%) and in burns (32.5%). The principal sites of infection were pneumonia (49.5%) followed by urinary tract infection (23.8%). The tracheal intubation and long-term vesical catheterization were significantly related to most pneumonias (60.3%; p<0.001) and urinary tract infection (77.3%; p<0.001), increasing the risk for such infections on 20 and 6 times, respectively. Sepsis occurred in 44.7% of patients. A wide range of microorganisms showed resistance to antimicrobials, and Acinetobacter baumannii (92.7%, p <0.001) and Klebsiella pneumoniae (70.5%, p <0.001) were the most prevalent. 28.8% of the patients evolved to death, and 96.8% of deaths were related to infections. The relation between infections and death was statistically significant in pneumonia patients (37.8%, p <0.001) and sepsis (54.2%, p <0.001). The association of infections with the death showed the negative impact of this health complication in trauma patients.
