ABSTRACT

ABSTRACT Background: Papiliotrema laurentii is one of several non-neoformans cryptococci that have rarely been associated with human infection, since it was previously considered saprophyte and thought to be non-pathogenic to humans. Nevertheless, increasing number of reports of human infection have emerged in recent years, mostly in oncologic patients. Aim: To report a case of a female patient with pyloric obstructive cancer with a catheter-related Papiliotrema laurentii blood stream infection and systematically review the available evidence on P. laurentii infection in humans. Methods: Retrieval of studies was based on Medical Subject Headings and Health Sciences Descriptors, which were combined using Boolean operators. Searches were run on the electronic databases Scopus, Web of Science, MEDLINE (PubMed), BIREME (Biblioteca Regional de Medicina), LILACS (Latin American and Caribbean Health Sciences Literature), Cochrane Library for Systematic Reviews and Opengray.eu. There was no language or date of publication restrictions. The reference lists of the studies retrieved were searched manually. Results: The search strategy retrieved 1703 references. In the final analysis, 31 references were included, with the description of 35 cases. Every patient but one had a previous co-morbidity - 48.4 % of patients had a neoplasm. Amphotericin B was the most used treatment and only a single case of resistance to it was reported. Most patients were cured of the infection. Conclusion: P. laurentii infection in humans is usually associated to neoplasia and multiple co-morbidities, and amphotericin B seems to be a reliable agent for treatment.

ABSTRACT

RESUMO Objetivo: Determinar os fatores de risco para contrair infecções da corrente sanguínea associadas a cateter de acesso central em unidades de terapia intensiva pediátrica, e investigar a incidência e a etiologia dessas infecções nas unidades de terapia intensiva pediátrica com diferentes perfis. Métodos: Este foi um estudo prospectivo de coorte, conduzido em três hospitais. Um deles é um grande hospital público metropolitano, com duas unidades de terapia intensiva pediátrica que contabilizam 19 leitos; o segundo é um hospital regional com oito leitos em unidade de terapia intensiva pediátrica; e o terceiro é um hospital privado com 15 leitos de terapia intensiva pediátrica. Incluíram-se pacientes com idades entre 1 mês e 18 anos, que utilizaram cateter de acesso venoso central por pelo menos 24 horas. Registramos a evolução diária dos pacientes. Colheram-se dados gerais sobre o paciente e sobre o cateter, utilizados como variáveis. Todos os dados foram analisados com utilização do pacote estatístico Statistical Package for Social Science (SPSS), versão 13.0, para comparação de pacientes com infecção da corrente sanguínea associada a cateter com ou sem fatores de risco. Resultados: Durante o período do estudo admitiram-se às unidades de terapia intensiva 728 pacientes; deles, 170 tiveram cateter de acesso venoso central instalado por, no mínimo, 24 horas. A mediana de idade foi de 32 meses, e 97 (57%) dos pacientes eram do sexo masculino. A taxa de incidência de infecções da corrente sanguínea relacionadas a cateter foi de 3,9/1.000 cateteres venosos centrais-dias. A incidência variou entre os hospitais, sendo de 1,6 a 6,6. A taxa geral de mortalidade foi de 11,1%, e as taxas de mortalidade com e sem infecções da corrente sanguínea relacionadas a cateter foram, respectivamente, de 12,9% e 10,7%. Na análise multivariada, os fatores de risco para ocorrência de infecções da corrente sanguínea relacionadas a cateter foram maior tempo de uso do cateter venoso central (OR: 1,07; IC95% 1,00 - 1,14; p = 0,019) e o uso de mais de um cateter venoso central de uma vez (OR: 2,59; IC95% 1,17 - 5,73; p = 0,048). Conclusão: Maior duração do uso de cateter venoso central e mais de um cateter venoso central de uma vez foram os principais fatores de risco para infecções da corrente sanguínea associadas a cateter em unidades de terapia intensiva pediátrica.


ABSTRACT Objectives: To determine the risk factors for acquiring central line-associated blood stream infections (CLABSI) in pediatric intensive care units and to investigate the incidence and etiology of CLABSI in pediatric intensive care units with different profiles. Methods: The study was a prospective cohort study in three hospitals. One of the hospitals is a large metropolitan public hospital with two pediatric intensive care units and a total of nineteen pediatric intensive care unit beds, another is a regional hospital with eight pediatric intensive care unit beds, and the third is a private hospital with fifteen beds. Patients between the ages of 1 month old and 18 years old who used a central venous catheter for over 24 hours were included. We recorded patients' daily progress. General patient and catheter-related data were collected and used as variables. All the data were analyzed using Statistical Package for Social Science (SPSS), version 13.0, to compare patients with CLABSI with or without risk factors. Results: A total of 728 patients were admitted to the pediatric intensive care units, and 170 had a central line in place for at least 24 hours. The median age was 32 months, and 97 (57%) of the patients were males. The CLABSI incidence rate was 3.9/1000 central venous catheter-days. The incidence among hospitals varied from 1.6 to 6.6. The overall mortality rate was 11.1%, and the CLABSI and non-CLABSI mortality rates were 12.9% and 10.7%, respectively. In multivariate analysis, independent risk factors for CLABSI were a longer duration of central venous catheter use (OR: 1.07; 95%CI 1.00 - 1.14; p = 0.019) and the use of more than one central venous catheter at once (OR: 2.59; 95%CI 1.17 - 5.73; p = 0.048). Conclusion: A longer duration of central venous catheter use and the use of more than one central venous catheter at once were the main risk factors for CLABSI in pediatric intensive care units.

ABSTRACT

Resumen Las infecciones asociadas a diálisis peritoneal (DP), corresponden a la principal complicación de los pacientes pediátricos en esta terapia de reemplazo renal, disminuyendo la sobrevida de la membrana peritoneal y empeorando el pronóstico del paciente. El reconocimiento precoz y un tratamiento oportuno de éstas son fundamentales para preservar esta modalidad dialítica. Se presenta una revisión actualizada de la literatura científica, con el fin de entregar recomendaciones reproducibles en los distintos centros pediátricos que realizan diálisis peritoneal crónica en niños.


Peritoneal dialysis-related infections are the main complication in pediatric patients undergoing this renal replacement therapy, associating a high rate of morbidity, generating also a decreasing survival of the peritoneal membrane and worsening the patient outcome. We describe the recommended diagnostic and therapeutic modalities to treat dialysis-related in children.

ABSTRACT

Abstract Objective: This was a systematic review of the incidence density and risk factors for central venous catheter-related infections in a neonatal population. Data source: The MEDLINE, Embase, Cochrane, BDENF, SciELO, and LILACS databases were used without date or language restriction. Studies that analyzed risk factors for bloodstream infections in newborns were identified. Data synthesis: A total of 134 articles were found that met the eligibility criteria. Of these articles, 14 were selected that addressed risk factors for central venous catheter-related infection in neonates. Catheter-related bloodstream infections remain an important complication, as shown by the incidence rates reported in the studies included in this review. The observed risk factors indicate that low birth weight, prematurity, and longer catheter permanence are related to a higher incidence of bloodstream infections. It has been observed that low rates of catheter-related infections, i.e., close to zero, are already a reality in health institutions in developed countries, since they use infection surveillance and control programs. Conclusion: Catheter-related bloodstream infections still show high incidence density rates in developing countries. The authors emphasize the need for further longitudinal studies and the need for better strategies to prevent risk factors, aiming at the reduction of catheter-related infections.


Resumo Objetivo: Revisão sistemática sobre a densidade de incidência e de fatores de risco para infecção associada a cateter venoso central em população neonatal. Fontes dos dados: Usaram-se os bancos de dados Medline, Embase, Cochrane, Bdenf, Scielo e Lilacs, sem restrição de data ou de idioma. Identificaram-se os estudos que analisaram fatores de risco para infecção da corrente sanguínea em recém-nascidos. Síntese dos dados: Foram encontrados 134 artigos conforme os critérios de elegibilidade. Desses, foram selecionados 14 que abordaram fatores de risco para infecção associada a cateter venoso central em neonatos. A infecção da corrente sanguínea associada a cateter continua a mostrar-se como uma importante complicação, conforme demonstram as taxas de incidência relatadas nos estudos incluídos nesta revisão. Os fatores de risco observados apontam que baixo peso ao nascer, prematuridade e maior tempo de permanência do cateter estão relacionados a maior incidência de infecção da corrente sanguínea. Observou-se que taxas de infecção associada a cateter em valores baixos, próximos a zero, já são uma realidade em instituições de saúde de países desenvolvidos, uma vez que usam programas de vigilância e controle de infecção. Conclusão: A infecção da corrente sanguínea associada a cateter ainda apresenta altas taxas de densidade de incidência em países em desenvolvimento. Destaca-se a necessidade de mais estudos longitudinais e a necessidade de melhores estratégias de prevenção dos fatores de risco para a redução de infecção associada a cateter.

ABSTRACT

Abstract INTRODUCTION: Bloodstream infections are the second most common cause of death among patients on hemodialysis. This study aimed to evaluate the incidence of and risk factors associated with central venous catheter-related infections in patients undergoing hemodialysis, and to identify and characterize the type and antimicrobial susceptibility profiles of the primary microorganisms isolated during one year of follow-up. METHODS: A prospective cohort study was conducted in 2014 in a hemodialysis referral center. We included 200 outpatients with acute kidney injury who had no permanent venous access. A nurse assessed the patients for signs of infection three times per week during dressing changes. The clinicopathologic characteristics of patients with and without local or systemic infection were compared. RESULTS: Fifty-five episodes of catheter-related infections occurred in 43 (22%) patients; 38 (69%) were bloodstream infections and 17 (31%) were local infections. Thirty-two (75%) patients with infection had femoral vein catheter placement. In total, 6,240 hemodialysis sessions were performed; the rates of primary bloodstream and local infection were 6.1 and 2.7 episodes per 1,000 patients on daily dialysis, respectively. In the univariate analysis, diabetes was significantly associated with the development of infection, while level of education, ethnicity, age, and sex were not. Gram-negative bacteria were primarily isolated from blood culture specimens (55% of samples). Of the Gram-negative isolates, 56% were resistant to the carbapenems. CONCLUSIONS: We identified a high incidence of catheter-related infections caused by resistant microorganisms in patients undergoing hemodialysis via central venous catheters.

ABSTRACT

Trichosporon asahii es un hongo ubicuo que se ha aislado como parte de la microbiota humana. Recientemente, se ha visto una emergencia de este patógeno en infecciones tanto localizadas como sistémicas. En unidades de cuidados intensivos pediátricos para quemados, existen escasos reportes de infecciones del tracto urinario por este microorganismo. Se describen 2 pacientes pediátricos con internación prolongada por quemaduras extensas y múltiples tratamientos antibióticos previos. Ambos presentaron sepsis por infección del tracto urinario asociada a sonda vesical por Trichosporon asahii. En ambos pacientes, se realizó el recambio de la sonda vesical y tratamiento con voriconazol por 10 días, con buena evolución. En los casos presentados, debido a la ausencia de otros aislamientos microbiológicos y a la buena respuesta al tratamiento antifúngico junto con el recambio de la sonda vesical, se asumió al Trichosporon asahii como el probable agente causal de la sepsis.


Trichosporon asahii is a ubiquitous fungus that has been isolated as part of human microbiota. There has been an emergence of this pathogen in recent years, causing superficial and deep seated infections. There are scarce reports of urinary tract infections in pediatric intensive care burn units caused by this agent. We describe the cases of 2 pediatric patients with prolonged hospitalization due to severe burns that had received several antibiotic courses for previous infections. Both presented sepsis secondary to catheter related urinary tract infection by Trichosporon asahii. Both patients underwent urinary catheter replacement and were treated effectively with voriconazole for 10 days. In the cases presented, sepsis was assumed to be due to Trichosporon asahii since no other microorganism was identified and the patients showed favorable outcome with the prescribed treatment with voriconazole and replacement of the urinary catheter.

ABSTRACT

ABSTRACT Objective: To evaluate the impact of the implementation of insertion and maintenance bundles on the rates of catheter-related bloodstream infection in an intensive care unit. Method: This is a quasi-experimental, before-and-after study with a non-equivalent control group. During a six-month period, insertion and maintenance bundles for the central venous catheters were implemented. Supervision guidelines were developed to assess compliance with the bundle and catheter characteristics. Results: A total of 444 central catheters corresponding to 390 patients were observed, of which 68.7% were inserted in the unit. The maintenance and insertion bundles reached 62.9% and 94.7% compliance, respectively, and 50.7% of the insertions were supervised. It was possible to observe a 54.5% decrease in the rate of central catheter infection (3.48 vs 1.52 x 1000 days/catheter, p<0.05) when compared with the control group. Conclusion: The simultaneous implementation of insertion and maintenance bundles has a positive impact on the reduction of catheter-related bloodstream infection; therefore it is an efficient alternative to improve the quality and safety of care in high complexity units.

ABSTRACT

Background: Infectious complications associated to central venous catheter (CVC) increase morbidity, mortality and costs. Total parenteral nutrition (TPN) is one of the risk factors described for catheter-related bloodstream infection (CR-BSI). The aim of this study was explore if TPN and time of exposition, are risk factors for CR-BSI among patient exposed to this therapy. Patients and Methods: Cohort study of patients with CVC exposed and not exposed to TPN with calculation of the relative risk (RR) for CR-BSI and percentage of CR-BSI according to different times of exposition to TPN. Study encompassed years 2010-2015 and only adult patients were included. Results: During the study period 51 events of CR-BSI were identified, with 27 occurring among those exposed to TPN and 24 among those not exposed. CR-BSI incidence rate was 6.3 in the group with TPN and 1.2 in those without this therapy (RR 5.4; IC 95 3.6-8.2). The percentage of patients with CR-BSI increased in parallel to exposition time (Pearson coefficient +0.91) and the OR increased for expositions ≥ 7 days (OR 2.8; IC 95 1.047.4; p < 0.05). Conclusions: Exposition to TPN increases the risk to CR-BSI in adult patients with CVC and this risk raise with exposition time.


Antecedentes: Las complicaciones infecciosas asociadas a dispositivos vasculares centrales tienen impacto en morbi-mortalidad y costos. Diferentes factores de riesgo han sido identificados en las ITS/CVC, incluyendo la nutrición parenteral total (NPT). Objetivo: Determinar si la NPT y el tiempo de exposición constituyen factores de riesgo para desarrollar ITS/CVC. Pacientes y Método: Estudio de cohortes de diseño prospectivo, de pacientes adultos con catéter venoso central (CVC) convencional, internados en el Hospital Militar entre los años 2010 y 2015 y que estuvieron expuestos o no expuestos a NPT, calculando el riesgo relativo (RR) y la distribución porcentual de las ITS/CVC a diferentes intervalos de exposición de NPT con análisis de coeficiente de correlación y cálculo de Odds Ratio (OR). Resultados: Durante el período de estudio se registraron 51 eventos de ITS/CVC en pacientes adultos con CVC, de los cuales 27 estuvieron expuestos a NPT y 24 no. Incidencia de 6,3 por 1.000 días en expuestos a NPT vs 1,2 en no expuestos (RR de 5,4; IC 95 3,6 a 8,2). La proporción de pacientes con ITS/CVC aumentó a medida que aumentaba la exposición a NPT (coeficiente correlación r = +0,91), siendo significativa para exposiciones ≥ 7 días (OR 2,8; IC 95 1,04-7,4; p < 0,05). Conclusiones: La exposición a NPT aumenta el riesgo de ITS/CVC en pacientes adultos hospitalizados respecto a aquellos pacientes que no reciben NPT, además este riesgo aumenta con el tiempo de exposición.

ABSTRACT

Objective: to analyze the complications related to peritonitis and catheter exit-site infections, in patients on peritoneal dialysis at home.Method: quantitative and cross-sectional study, carried out with 90 patients on peritoneal dialysis at home, in a municipality in the Northeast region of Brazil. For data collection, it was used two structured scripts and consultation on medical records. Descriptive analysis and comparison tests among independent groups were used, considering p<0.05 as level of statistical significance.Results: by comparing the frequency of peritonitis and the length of treatment, it was found that patients over two years of peritoneal dialysis were more likely to develop peritonitis (X²=6.39; p=0.01). The number of episodes of peritoneal catheter exit-site infection showed association with the length of treatment (U=224,000; p=0.015).Conclusion: peritonitis and catheter exit-site infection are associated with the length of treatment.

ABSTRACT

OBJECTIVE: to relate the variables from a surveillance form for intravenous devices in high risk newborn infants with peripherally inserted central catheter related infection. METHODOLOGY: approximately 15 variables were studied, being associated with peripherally inserted central catheter related infection, this being defined by blood culture results. The variables analyzed were obtained from the surveillance forms used with intravenous devices, attached to the medical records of newborn infants weighing between 500 and 1,499 g. The statistical association was defined using the Chi-squared and Student t tests. The study was approved by the Research Ethics Committee of the Instituto Fernandes Figueira under process N. 140.703/12. RESULTS: 63 medical records were analyzed. The infection rate observed was 25.4%. Of the variables analyzed, only three had a statistically-significant relationship with the blood culture - the use of drugs capable of inhibiting acid secretion, post-natal steroid use, and undertaking more than one invasive procedure (p-value of 0.0141, 0.0472 and 0.0277, respectively). CONCLUSION: the absence of significance of the variables of the form may be related to the quality of the records and to the absence of standardization. It is recommended that the teams be encouraged to adhere to the protocol and fill out the form. .


OBJETIVO: relacionar as variáveis de um formulário de vigilância para dispositivos intravenosos em recém-nascido de alto risco, com infecção relacionada ao uso de cateter central de inserção periférica. METODOLOGIA: foram estudadas cerca de 15 variáveis associando-as à infecção por uso do cateter central de inserção periférica, sendo essa definida pelo resultado da hemocultura. As variáveis analisadas foram obtidas nos formulários de vigilância do uso de dispositivo intravenoso, anexados aos prontuários de recém-nascidos de 500 a 1.499g. A associação estatística foi definida pelos testes qui-quadrado e t de Student. O estudo encontra-se aprovado pelo Comitê de Ética em Pesquisa do Instituto Fernandes Figueira sob nº140.703/12. RESULTADOS: foram analisados 63 prontuários. A taxa de infecção observada foi de 25,4%. Das variáveis analisadas, apenas três apresentaram relação estatisticamente significativa com a hemocultura - o uso de drogas inibidoras de secreção ácida, o uso de esteroides pós-natal e a realização de mais de um procedimento de quebra de barreira (p-valor de 0,0141, 0,0472 e 0,0277, respectivamente). CONCLUSÃO: a ausência de significância das variáveis do formulário pode estar relacionada com a qualidade dos registros e ausência de padronização. Recomenda-se incentivo às equipes para a aderência ao protocolo e preenchimento do formulário. .

ABSTRACT

Rhizobium radiobacter es una bacteria Gram-negativa, fijadora de nitrógeno que se encuentra principalmente en el suelo. Rara vez causa infecciones en humanos. Ha sido asociada a bacteriemia secundaria a colonización de catéteres intravasculares en pacientes inmunocomprometidos. El objetivo de este trabajo es informar un caso de endocarditis infecciosa por R. radiobacter. Se trata de paciente masculino, de 47 años de edad, con diagnóstico de enfermedad renal crónica estadio 5 en tratamiento sustitutivo con hemodiálisis, quien acude a centro asistencial por presentar fiebre de dos semanas de evolución. Es hospitalizado, se toman muestras de sangre periférica para hemocultivo y se inicia antibioticoterapia empírica con cefotaxime más vancomicina. El ecocardiograma transtorácico revelo vegetación fusiforme en válvula tricúspide con regurgitación grado III-IV/IV. Al séptimo día del inicio de la antibioterapia el paciente presenta mejoría clínica y paraclínica. La bacteria identificada por hemocultivo es Rhizobium radiobacter resistente a ceftriaxona y sensible a imipenem, amikacina, ampicilina y ampicilina/sulbactam. Debido a la mejoría clínica se decide continuar tratamiento con vancomicina y se anexa imipenem. A los 14 días de iniciada la antibioterapia el paciente es dado de alta con tratamiento ambulatorio con imipenen hasta cumplir seis semanas de tratamiento. En el ecocardiograma control se evidencio ausencia de la vegetación en la válvula tricúspide. Este caso sugiere que R. radiobacter puede ser una causa de endocarditis en pacientes portadores de catéteres intravasculares.


Rhizobium radiobacter is a Gram-negative, nitrogen-fixing bacterium, which is found mainly on the ground. It rarely causes infections in humans. It has been associated with bacteremia, secondary to colonization of intravascular catheters, in immunocompromised patients. The aim of this paper was to report the case of an infective endocarditis caused by R. radiobacter, in a 47-year-old male, diagnosed with chronic kidney disease stage 5, on replacement therapy with hemodialysis and who attended the medical center with fever of two weeks duration. The patient was hospitalized and samples of peripheral blood were taken for culture. Empirical antibiotic therapy was started with cefotaxime plus vancomycin. The transthoracic echocardiogram revealed fusiform vegetation on the tricuspid valve, with grade III-IV/IV regurgitation. On the seventh day after the start of antibiotic therapy, the patient had a clinical and paraclinical improvement. The bacterium identified by blood culture was Rhizobium radiobacter, ceftriaxone-resistant and sensitive to imipenem, amikacin, ampicillin and ampicillin/ sulbactam. Because of the clinical improvement, it was decided to continue treatment with vancomycin and additionally, with imipenem. At 14 days after the start of antibiotic therapy, the patient was discharged with outpatient treatment with imipenem up to six weeks of treatment. The control echocardiogram showed the absence of vegetation on the tricuspid valve. This case suggests that R. radiobacter can cause endocarditis in patients with intravascular catheters.

ABSTRACT

Red cell exchange/transfusion is frequently used in the management of patients with medical complications related to acute severe sickle cell disease [SCD]. However, peripheral venous access is often difficult without central venous catheters [CVCs] in adult patients with moderate or severe SCD. To review our experience with the use of the PORT-A-CATH device in sixteen patients with SCD undergoing exchange or simple transfusions. Among a cohort of 550 patients who frequently visited the inpatient service, sixteen SCD patients required the insertion of a PORT-A-CATH device. These patients included 3 males and 13 females, aged 25-44years [31.1 +/- 2.3; mean +/- [SD]. A total of 24 PORT-A-CATH devices were implanted in these 16 patients during the study period. Eleven patients had 1 device implanted, three patients had 2 devices, one patient had 3 devices, and one patient had 4 devices implanted. Out of the 24 devices implanted, 17 required removal, due to either infection associated with sepsis and/or thrombosis. The organisms involved were Candida spp. [3], C. Parapsilosis [2], C. albicans [1], C. famata [1], C. lusitanice [1], Staphylococcus spp. [6], and S. aureus [3], as well as the coagulase-negative Staphylococcus [2], alpha hemolytic Streptococcus [1], Diphtheroidbacilli [2], Pseudomonas aeruginosa [2], Ps. Spp. [3], Escherichia coli [3], Klebsiella oxytoca [1], Klebsiella pneumoniae [1], Klebsiella spp. [1], Serratia liquefaciens [1], Serra-tia fanticola [1], Achromobacter spp. [2] Chromobacterium violaceum [1], Delftia acidovirans [1], Stenotrophomonas maltophile [1], Alcaligenes faecalis [1], and Enterobacter cloacae [1]. Two episodes of documented thrombosis were observed

ABSTRACT

Dressing is an intervention aimed to prevent infection in central venous catheter. This study aimed to analyze the frequency of catheter-related infection and skin toxicity in the use of transparent film in Hickman’s catheter in patients who underwent allogeneic hematopoietic stem cell transplantation. A case series with 10 cases was carried out. Due to the presence of exudate on the average for 12 days, sterile gauze dressing was used for 12.9 days (average). Transparent film was used, on average, for 15.1 days. Catheters were precociously removed due to infection in four cases. The highest degree of skin toxicity occurred in a case that used gauze dressing and in three cases with film. The transparent film permitted visualization of the exit site of the catheter and changes with longer intervals.


O curativo é intervenção que visa a prevenção de infecção no cateter venoso central. O estudo teve como objetivo analisar a frequência de infecção, relacionada ao cateter, e toxicidade cutânea, na utilização do curativo de poliuretano no cateter de Hickman, implantado em pacientes submetidos ao transplante de células-tronco hematopoéticas alogênico. Para tal, realizou-se uma série de casos, constituída por 10 casos. O exsudato esteve presente em média por 12 dias, sendo necessário o uso do curativo de gaze estéril, com fita adesiva, por 12,9 dias (média). O curativo de poliuretano foi utilizado, em média, por 15,1 dias. A retirada precoce do cateter por infecção ocorreu em quatro casos. O maior grau de toxicidade cutânea aconteceu em um caso que utilizou o curativo de gaze e em três casos com filme. O filme transparente permitiu a visualização do sítio de saída do cateter e a troca com intervalos maiores.

ABSTRACT

The objective of the study was to determine the effect of switching from an open (glass or semi-rigid plastic) infusion container to a closed, fully collapsible plastic infusion container (Viaflex®) on rate and time to onset of central lineassociated bloodstream infections (CLABSI). An open-label, prospective cohort, active healthcare-associated infection surveillance, sequential study was conducted in three intensive care units in Brazil. The CLABSI rate using open infusion containers was compared to the rate using a closed infusion container. Probability of acquiring CLABSI was assessed over time and compared between open and closed infusion container periods; three-day intervals were examined. A total of 1125 adult ICU patients were enrolled. CLABSI rate was significantly higher during the open compared with the closed infusion container period (6.5 versus 3.2 CLABSI/1000 CL days; RR=0.49, 95 percentCI=0.26- 0.95, p=0.031). During the closed infusion container period, the probability of acquiring a CLABSI remained relatively constant along the time of central line use (0.8 percent Days 2-4 to 0.7 percent Days 11-13) but increased in the open infusion container period (1.5 percent Days 2-4 to 2.3 percent Days 11-13). Combined across all time intervals, the chance of a patient acquiring a CLABSI was significantly lower (55 percent) in the closed infusion container period (Cox proportional hazard ratio 0.45, p= 0.019). CLABSIs can be reduced with the use of full barrier precautions, education, and performance feedback. Our results show that switching from an open to a closed infusion container may further reduce CLABSI rate as well as delay the onset of CLABSIs. Closed infusion containers significantly reduced CLABSI rate and the probability of acquiring CLABSI.

ABSTRACT

To establish the bacteriological profile of catheter related infections in patients having various indwelling medical devices. Descriptive study. The study was conducted in the Children Hospital and Institute of Child Health, Lahore during November 2005 to March 2006. A total of 100 culture positive samples from these patients were included comprising of 68 samples of Endotracheal Tubes, 14 samples of Peritoneal Dialysis Catheters, 11 samples of Urinary Catheters and 7 samples of Central Venous Catheters. The most frequent catheter colonizing bacteria were Pseudomonas spp. [34.7%], Klebsiella spp. [27.8%]. Escherichia coli [23.5%], Staphylococcus aureus [5.2%], Coagulase negative Staphylococci [3.5%], Proteus spp. [3.5%], Streptococcus pyogenes [0.9%] and non-haemolytic Streptococci [0.9%]. Catheter related infection remains an ongoing problem which cannot be completely eradicated; however by basic rules of hygiene it can be minimized
