Atuação do enfermeiro na rede básica de saúde frente a gestante com infecção do trato urinário

The Urinary Tract Infection (UTI) in pregnancy is important as a consequence of the high incidence during the gestation. It is the third most common clinical complication in pregnancy affecting 10-12% of women whether prevalence is increasing in the first trimester of pregnancy, it may also contribute to maternal and infant mortality. Due the relevance for the results of obstetric and neonatal complications from UTI, these complications must be prevented, because it can lead to health hazards to pregnant women and newborns, producing a direct effect on morbidity and perinatal mortality. On this basis, it was defined as objectives of this research the identification of the profile of nurses from the Family Health Strategy (FHS) in the East and West Health Districts from the city of Natal / RN before the women with UTI and to verify the nurse performance during prenatal consultations. This is an exploratory study with a quantitative approach using a sample of 40 nurses active workers during this survey, it was approved by the Research Ethics Committee of the Universidade Federal do Rio Grande do Norte Protocol n0 232/10 P-CEP/UFRN and opinion n0 080/2011. The tool for data collection was a structured interview. The data collected were organized into an electronic database application Microsoft ® Excel 2007, exported and analyzed using the Statistical Package for Social Sciences (SPSS) version 17.0, and coded, tabulated and presented through tables and charts into their respective percentage distributions, using the descriptive and inferential statistical analysis, chi-square test and significance level of 5% (distribution in relative and absolute frequencies) in the independent variables. Therefore, it was observed from these results that the longer action of nurses in the FHS from the East and Weast health districts of the city of Natal/RN contributed to the development of a greater number of activities to control the incidence of UTI in women who are attended in the prenatal care service, proven by significance in statistics

Carga de trabalho de enfermagem e infecções relacionadas à assistência à saúde na unidade de terapia intensiva

In recent decades, the search for quality care has been widely discussed by the institutions and health professionals. In this context, it is the nurse coordinator of the process of providing nursing staff, reflecting the commitment to quality of care. In this process, it is the appearance of Infections Related to health care and its potential association with the workload in nursing as a valuable indicator of quality of care. Thus, this research contributes to studies to characterize the demand of nursing work to promote a safe healthcare practice. This study aimed to identify the association of nursing workload with the number of cases of Ventilator-Associated Pneumonia, urinary tract infection and central venous catheter infection in the intensive care unit. This is a quantitative research approach, descriptive, cross-sectional and prospective, held at Unimed Hospital in Natal-RN. The study population consisted of all patients treated in the Intensive Care Unit, Hospital for a period of 90 consecutive days in 2011. The convenience sample was compostapelos patients admitted to the ICU during the period of data collection, a total sample of 286 patients. To perform the data analysis software were used: Statistica 6.0, SPPS (Statistical Package for Social Sciences) version 17.0 (2004) and Excel 2007. In the descriptive analysis, we used Measures of Central Tendency and Measures of Dispersion or Variability and the use of nonparametric tests. Of the 286 patients, 88 were from the ICU and 198 ICU II II. Males predominated in the ICU I (51.1%) and female ICU II (57.6%) patients in the ICU I were aged 61-80 years (39.8%) followed by greater than 80 years (39.8%). In the ICU II, most of the patients were aged 61-80 years (38.9%) and then from 41 to 60 years (24.2%). In relation to the class of TISS inlet predominant class II in the two ICUs (59.1%), followed by Class III also in the two units (34.6%). Most patients (70.6%) out of the ICUs belonging to class II TISS. In the ICU I, the average number of forms of the TISS 28 was 6, has in ICU II this value drops to 3.2 forms. The overall mean was 19.9 TISS points in ICU patients I and ICU II.the 17 points in the average hours required to provide adequate nursing care to patients in the ICU I found that is 10 , 7 hours, and the ICU II 9.2 hours. It was found that the time provided by the nursing staff were higher in ICU II, with an average of 19 hours available for nurses in this sector. In the ICU I, which showed higher need of available hours, it was found that the mean value of 12.7 available hours. It was found that only 2.4% of patients had these units Ventilator-Associated Pneumonia, 1.0% were infected central venous catheter and 1.4% of patients had urinary tract infection. Infection associated with health care occurs, on average, on the tenth day of hospitalization. In the ICU II, this average value extends to the twelfth day with an excess of 2.7 hours of nursing care while in ICU I value decays to the ninth day of hospitalization with a deficiency of 12-hour assistance. It is concluded that patients generally showed a need for classification of semi-intensive care and has been assisted in their need to load. As for his association with the Related Infections Health will assist this analysis could not be performed due to the small number of notifications in this period. It is suggested further study how other factors related to infections me a longer period of analysis

Complications and risk factors in transrectal ultrasound-guided prostate biopsies

CONTEXTO E OBJETIVO: A biópsia da próstata não é um procedimento isento de riscos. Existe preocupação com respeito às complicações e quais seriam os melhores antibióticos usados antes do procedimento. O objetivo foi determinar a taxa de complicações e os possíveis fatores de risco para complicação na biópsia da próstata. TIPO DE ESTUDO E LOCAL: Estudo prospectivo clínico, realizado no Hospital das Clínicas de Botucatu. MÉTODOS: Foram realizadas biópsias em 174 pacientes que apresentavam anormalidade ao exame digital da próstata ou antígeno prostático específico maior que 4 ng/ml ou ambos. Todos os pacientes realizaram enema e antibioticoprofilaxia previamente ao exame. As complicações foram anotadas após o término do procedimento e em consultas posteriores. Algumas condições foram investigadas como possíveis fatores de risco para biópsias de próstata: idade, câncer da próstata, diabetes melito, hipertensão arterial sistêmica, antecedentes de prostatite, uso de ácido acetilsalicílico, volume prostático, número de biópsias e uso de sonda vesical. RESULTADOS: As complicações hemorrágicas foram mais comuns (75,3%) enquanto que as infecciosas ocorreram em 19% dos casos. O tipo mais freqüente foi a hematúria, ocorrendo em 56% dos pacientes. A infecção do trato urinário ocorreu em 16 pacientes (9,2%). Sepse foi observada em três pacientes (1,7%). Não houve óbitos. em 20% dos pacientes não foram observadas complicações após o exame. A presença da sonda vesical foi fator de risco para complicações infecciosas (p < 0,05). O número maior de amostras nas biópsias foi relacionado à hematúria, sangramento retal e complicações infecciosas (p < 0,05). As demais condições investigadas não se relacionaram com complicações pós-biópsia da próstata. CONCLUSÕES: As complicações pós-biópsia da próstata foram em sua maioria autolimitadas. A taxa de complicações graves foi baixa, sendo a biópsia de próstata guiada pelo ultra-som segura e eficaz. A retirada de um maior número de fragmentos na biópsia relaciona-se com hematúria, sangramento retal e complicações infecciosas. A sonda vesical foi um fator de risco para complicações infecciosas.

Factors predictive of inappropriateness in requests for parenteral antimicrobials for therapeutic purposes: A study in a small teaching hospital in Brazil

Background: The identification of patterns of inappropriate antimicrobial prescriptions in hospitals contributes to the improvement of antimicrobial stewardship programs (ASP). Methods: We conducted a cross-sectional study to identify predictors of inappropriateness in requests for parenteral antimicrobials (RPAs) in a teaching hospital with 285 beds. We reviewed 25% of RPAs for therapeutic purposes from y 2005. Appropriateness was evaluated according to current guidelines for antimicrobial therapy. We assessed predictors of inappropriateness through univariate and multivariate models. RPAs classified as 'appropriate' or 'probably appropriate' were selected as controls. Case groups comprised inappropriate RPAs, either in general or for specific errors. Results: Nine hundred and sixty-three RPAs were evaluated, 34.6% of which were considered inappropriate. In the multivariate analysis, general predictors of inappropriateness were: prescription on week-ends/holidays (odds ratio (OR) 1.67, 95% confidence interval (CI) 1.20-2.28, p = 0.002), patient in the intensive care unit (OR 1.57, 95% CI 1.11-2.23, p = 0.01), peritoneal infection (OR 2.15, 95% CI 1.27-3.65, p = 0.004), urinary tract infection (OR 1.89, 95% CI 1.25 -2.87, p = 0.01), combination therapy with 2 or more antimicrobials (OR 1.72, 95% CI 1.15-2.57, p = 0.008) and prescriptions including penicillins (OR 2.12, 95% CI 1.39-3.25, p = 0.001) or 1(st) generation cephalosporins (OR 1.74, 95% CI 1.01-3.00, p = 0.048). Previous consultation with an infectious diseases (ID) specialist had a protective effect against inappropriate prescription (OR 0.34, 95% CI 0.24-0.50, p < 0.001). Factors independently associated with specific prescription errors varied. However, consultation with an ID specialist was protective against both unnecessary antimicrobial use (OR 0.04, 95% CI 0.01-0.26, p = 0.001) and requests for agents with an insufficient antimicrobial spectrum (OR 0.14, 95% CI 0.03-0.30, p = 0.01). Conclusions: Our results demonstrate the importance of previous consultation with an ID specialist in assuring the quality of prescriptions. Also, they highlight prescription patterns that should be approached by ASP policies.

Fatores associados à recorrência da infecção do trato urinário em crianças

OBJETIVOS: verificar a freqüência de infecção urinária recorrente (ITU) e avaliar os fatores associados à recorrência da ITU em crianças. MÉTODOS: estudo retrospectivo de 95 pacientes com seguimento de um ano (68 meninas e 27 meninos, mediana de idade três anos). As variáveis estudadas foram: sexo, idade, febre, constipação, tipo de bactéria, refluxo vésico-ureteral (RVU), anormalidades na cintilografia renal com ácido dimercaptosuccínico (DMSA). RESULTADOS: infecção urinária recorrente ocorreu em 49,5% crianças (19 com trato urinário normal, 19 com RVU e 9 com estenose da junção pielocalicial). Comparando o grupo com ITU recorrente com o grupo sem ITU recorrente não se encontrou diferença significativa entre sexos, presença de febre, constipação e anormalidades na cintilografia renal com DMSA. A ITU recorrente foi significativamente maior nas crianças com um ano ou menos, naquelas menores de dois anos com RVU, nas com bactéria diferente da Escherichia coli e sem profilaxia antibacteriana. Os fatores de risco significativos para a recorrência ITU foram idade < 2 anos (OR = 3,83) e refluxo vésico-ureteral (OR = 4,95). CONCLUSÕES: por causa da elevada freqüência de ITU recorrente é importante o seguimento regular de grupo de crianças com fatores de risco para ITU recorrente.

Cicatrizes renais em crianças com refluxo vesicoureteral primário

OBJETIVO: verificar a incidência de cicatrizes renais em crianças com refluxo vesicoureteral primário, comparando com sexo, idade no diagnóstico, infecção febril, grau do refluxo e tipo de bactéria. MÉTODOS: estudo retrospectivo de 58 crianças, com idade entre dois meses a 11 anos, apresentando refluxo vesicoureteral primário, detectado pela uretrocistografia miccional, após episódio documentado de infecção urinária. Diagnóstico de cicatriz renal foi obtido pela cintilografia com DMSA cinco meses, no mínimo, após o tratamento da infecção urinária; em 40 crianças, o exame foi repetido após período de seis meses a seis anos. RESULTADOS: 45 crianças (77,6%) eram meninas e 13 (22,4%) eram meninos, 51,7% com idade menor ou igual a 2 anos. A incidência de cicatriz renal foi de 55,2%. Houve maior proporção significativa de cicatrizes renais no sexo feminino, na presença do sintoma febre e no refluxo dilatado (III, IV e V). Presença de febre e sexo feminino foram fatores de risco significativos na ocorrência de cicatriz renal (febre - OR= 6,19, e sexo feminino - OR= 4,12). Houve tendência da presença de cicatriz renal em maiores de 2 anos. O intervalo entre início dos sintomas e a primeira consulta foi maior nas crianças com cicatrizes renais. Novas cicatrizes renais foram observadas em 12,5%. CONCLUSÃO: a presença de febre e sexo feminino foram fatores de risco para presença de cicatrizes renais, principalmente no refluxo vesicoureteral dilatado. A alta incidência de cicatrizes renais neste estudo pode estar relacionada ao retardo do diagnóstico do refluxo vesicoureteral.

Late presentation of posterior urethral valve: two case reports

CONTEXTO: Válvula de uretra posterior (VUP) é uma conhecida malformação congênita urinária, geralmente diagnosticada em exames ultra-sonográficos pré-natais ou ao nascimento. Raramente, esta doença pode ser encontrada em adolescentes e em adultos. RELATO DE CASOS: Este artigo mostra dois casos de VUP, encontrados em um adolescente e em um adulto. Ambos apresentavam sinais clínicos de infecção do trato urinário e sintomas obstrutivos infravesicais. Os diagnósticos foram realizados por uretrocistografia miccional e uretrocistoscopia. Fulguração endoscópica das válvulas foi o tratamento de escolha para ambos os casos. O acompanhamento demonstrou melhora importante dos sintomas após o tratamento.

Is the ultrasound-estimated bladder weight a reliable method for evaluating bladder outlet obstruction?

OBJECTIVETo evaluate the correlation between ultrasound-estimated bladder weight (UEBW) in patients with different degrees of bladder outlet obstruction (BOO).METHODSWe evaluated 50 consecutive non-neurogenic male patients with lower urinary tract symptoms (LUTS) referred to urodynamic study (UDS). All patients self-answered the International Prostate Score Symptoms (IPSS) questionnaire. After the UDS, the bladder was filled with 150 mL to determine UEBW.Patients with a bladder capacity under 150 mL, a previous history of prostate surgery or pelvic irradiation, an IPSS score <8, a bladder stone or urinary tract infection were excluded.After a pressure-flow study, the Schafer linear passive urethral resistance relation nomogram was plotted to determine the grade of obstruction: Grades I-II/VI were defined as mild obstruction, Grades III-IV/VI as moderate obstruction, and Grades V-VI/VI as severe obstruction.RESULTSThe UEBW was 51.7 +/- 26.9, 54.1 +/- 30.0 and 54.8 +/- 28.2 in patients with mild, moderate and severe BOO, respectively (P = 0.130). The UEBW allowed us to define four groups: (i) UEBW < 35 g; (ii) 35 g <= UEBW < 50 g; (iii) 50 g <= UEBW < 70 g; and (4) UEBW >= 70 g.We did not find any differences in age, prostate weight, IPSS, PVR, cystometric bladder capacity, presence of detrusor overactive and degree of obstruction in the aforementioned groups.CONCLUSIONDespite the fact that some studies have emphasized the value of UEBW as an efficient non-invasive method for evaluating lower urinary tract obstruction, our study suggests that UEBW does not present any individual correlation with LUTS or objective measurements of BOO.

Efeito protetor da microbiota cecal congelada e liofilizada sobre a infecção experimental de frangos de corte por Salmonella enterica sorovar Enteritidis

Estudaram-se os efeitos do tratamento de frangos de corte com microbiota cecal anaeróbia liofilizada (MCL) e congelada (MCC) sobre a infecção do trato digestivo das aves por Salmonella enterica sorovar Enteritidis. Foi usada microbiota intestinal sem prévia identificação bacteriana. A infecção foi persistente, em ordem, no ceco, inglúvio e duodeno. A infecção também foi autolimitante nos grupos tratados e no controle. Não ocorreu diferença entre o grupo-controle positivo e os tratados com MCL ou MCC. Houve redução da colonização do ceco no período de 12 dias após o desafio nos grupos tratados com MCL e MCC, o que não ocorreu no grupo-controle positivo. Não houve variação entre os tratamentos com MCL e MCC quanto às características pesquisadas. A S. Enteritidis reduziu o ganho de peso médio nas aves inoculadas. Os tratamentos com MCL e MCC minimizaram a redução de peso nos grupos infectados.

Perfil de sensibilidade e multirresistência em linhagens de Escherichia coli isoladas de infecção do trato urinário, de piometra e de fezes de cães

Susceptibility profile and multiple drug resistance in 158 E. coli strains isolated from urinary tract infection (UTI), pyometra, and feces of dogs were studied. Norfloxacin, ciprofloxacin, and enrofloxacin were the most-effective drugs (>60%) for E. coli strains. High rates of resistance to antimicrobials were observed in 60% or more of the isolated strains using sulfametoxazole/trimetoprim. Multiple drug resistance for three or more antimicrobials was observed in two (47.1%) strains isolated from UTI, seven (13.5%) from pyometra, and four (7.3%) from feces. From these, 17 (33.3%), one (1.9%), and three (5.5%), respectively, showed multiple resistance to five or more drugs.

Evaluation of the Diramic system for urine cultures

O sistema Diramic foi avaliado para o diagnóstico das infecções do trato urinário (ITU). O sistema Diramic foi desenvolvido em Cuba e possibilita resultados de diagnóstico das infecções do trato urinário (ITU) em quatro horas e baseia-se na variação da turvação do crescimento microbiano no meio de cultura após incubação a 37ºC/4 horas. 396 amostras de urinas provenientes de ambulatórios e enfermarias do HC da FMB-UNESP-Botucatu/SP foram analisadas pelo sistema Diramic. O método da alça calibrada (AC) foi adotado como método de referência. A taxa de coincidência entre os dois métodos foi de 96,46% (382 amostras de urina), não havendo diferença significativa entre os resultados obtidos nos dois métodos. Os resultados para sensibilidade e especificidade foram 84,37 e 98,80% respectivamente e 10 resultados no Diramic foram falsos negativos (2,5%) e 4 falso positivos (1,01%). Os microrganismos identificados nas urinas positivas foram Escherichia coli (68,75%), Klebsiella pneumoniae (10,94%), leveduras (6,25%), Pseudomonas aeruginosa (4,69%), Enterobacter cloacae (3,12%) e Proteus mirabilis, Staphyloccocus coagulase negativo, Morganella morganii e Citrobacter freundii também foram identificadas (1,56% para cada espécie). O método Diramic foi eficiente na triagem das urinoculturas, porém verificou-se algumas restrições quanto ao diagnóstico das infecções do trato urinário quando causadas por leveduras e em pacientes submetidos a antibioticoterapia.

Virulence factors of uropathogenic Escherichia coli from a University Hospital in Ribeirão Preto, São Paulo, Brazil

O objetivo do trabalho foi determinar a ocorrência de fatores de virulência, tais como, a expressão de fímbrias, produção de hemolisina, colicina e aerobactina em 100 cepas de Escherichia coli isoladas de pacientes ambulatoriais e hospitalizados de um hospital universitário de nível de atendimento terciário, entre os meses de julho e agosto de 2000, que apresentavam sinais clínicos e laboratoriais de infecção do trato urinário (ITU). Foram pesquisados os genes pap, afa e sfa responsáveis pela expressão de fímbrias através da técnica de PCR. A freqüência dos fatores de virulência entre as cepas estudadas foi de 96,0%, 76,0% e 24,0% para hemolisina, aerobactina e colicina respectivamente, e a prevalência dos genes para os sistemas de adesinas fimbriais foi de 32,0%, 19,0% e 11,0% para os genes pap, sfa e afa respectivamente. As cepas isoladas dos pacientes ambulatoriais exibiram um número maior de fatores de virulência quando comparadas com aquelas provenientes de indivíduos hospitalizados.

Predictors of incorrectness in antimicrobial prescription in the Bauru State Hospital (Bauru city, São Paulo State, Brazil)

The inappropriate use of antimicrobials in hospitals presents a negative impact on patient outcome and is associated with the emergence and spread of multidrug-resistant microorganisms. Antimicrobial stewardship programs (ASPs) have been instituted in order to improve the quality of prescriptions in hospitals. In this setting, the identification of patterns of inappropriate antimicrobial prescription is a valuable tool that allows ASPs to identify priorities for directing educative/restrictive policies. With this purpose, a study was conducted in the Bauru State Hospital, a teaching hospital with 285 beds affiliated to the Botucatu Medical School, São Paulo State University. The hospital maintains an active ASP since it was opened, in 2002. We selected 25% of the requests for parenteral antimicrobials (RPAs) from 2005 for analysis. Prescriptions for prophylactic purposes were excluded. All other RPAs were classified according to a modified Kunin and Jones categories. Univariate and multivariable analyses were performed to identify predictors of general inappropriateness and of specific prescription errors. Prescriptions classified as "appropriate'' or "probably appropriate" were selected as controls in all stages of the study. Among 963 RPAs included in our study, 34.6% were inappropriate. General predictors of inappropriateness were: prescription on weekends/holidays (OR = 1.67, 95% CI = 1.20-2.28, p = 0.002), patient from intensive care unit (OR = 1.57, 95% CI = 1.11-2.23, p = 0.01), peritoneal (OR = 2.15, 95% CI = 1.27-3.65, p = 0.004) or urinary tract infection (OR = 1.89, 95% CI = 1.25-2.87, p = 0.002), combined therapy with two or more antimicrobials (OR = 1.72, 95% CI = 1.15-2.57, p = 0.008) and prescriptions including penicillin (OR = 2.12, 95% CI = 1.39-3.25, p = 0.001) or first-generation cephalosporins (OR = 1.74, 95% CI = 1.01-3.00, p = 0.048). Previous consultation with an infectious diseases (ID) specialist had a protective effect against inappropriate prescription (OR = 0.34, 95% CI = 0.24-0.50, p < 0.001). Factors independently associated with specific prescription errors varied. However, consultation with an ID specialist was protective against both unnecessary antimicrobial use (OR = 0.04, 95% CI = 0.01-0.26, p = 0.001) and requests for agents with insufficient spectrum (OR = 0.14, 95% CI = 0.03-0.30, p = 0.01). In conclusion, the analysis of factors predictive of inappropriateness in antimicrobial prescription allowed us to identify issues requiring intervention. Also, it provided a positive feedback of the ASP efficacy, demonstrating the importance of previous consultation with an ID specialist to assure the quality of antimicrobial prescriptions.

Surveillance Programme for Healthcare Associated Infections in the State of São Paulo, Brazil. Implementation and the first three years' results

Governmental programmes should be developed to collect and analyse data on healthcare associated infections (HAIs). This study describes the healthcare setting and both the implementation and preliminary results of the Programme for Surveillance of Healthcare Associated Infections in the State of São Paulo (PSHAISP), Brazil, from 2004 to 2006. Characterisation of the healthcare settings was carried out using a national database. The PSHAISP was implemented using components for acute care hospitals (ACH) or long term care facilities (LTCF). The components for surveillance in ACHs were surgical unit, intensive care unit and high risk nursery. The infections included in the surveillance were surgical site infection in clean surgery, pneumonia, urinary tract infection and device-associated bloodstream infections. Regarding the LTCF component, pneumonia, scabies and gastroenteritis in all inpatients were reported. In the first year of the programme there were 457 participating healthcare settings, representing 51.1% of the hospitals registered in the national database. Data obtained in this study are the initial results and have already been used for education in both surveillance and the prevention of HAI. The results of the PSHAISP show that it is feasible to collect data from a large number of hospitals. This will assist the State of São Paulo in assessing the impact of interventions and in resource allocation. (C) 2010 The Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.
