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.

RESUMO Objetivo: Analisar o efeito da implementação de um protocolo de banho no leito em relação ao tempo livre de infecção e à prevalência de Infecção Relacionada à Assistência à Saúde. Método: Estudo quase experimental, com comparação entre dois grupos. No grupo controle, os dados foram coletados retrospectivamente entre janeiro e abril de 2018. A implementação do protocolo de banho no leito em uma Unidade de Terapia Intensiva ocorreu de maio a outubro de 2018. Os dados do grupo intervenção foram coletados de novembro de 2018 a fevereiro de 2019, por meio do acompanhamento diário durante o período de internação. Resultados: 157 participantes no grupo controle e 169 no grupo intervenção, com média de idade de 56 e 54 anos, respectivamente, sendo a maioria do sexo masculino. A ocorrência de Infecção Relacionada à Assistência à Saúde foi maior no grupo controle (n=32; 20,4%) comparado ao grupo intervenção (n=10; 5,9%), este que apresentou 2,86 menor risco de desenvolver Infecção Relacionada à Assistência à Saúde (p<0,01). O grupo intervenção apresentou maior tempo livre de infecção comparado ao grupo controle, estes que tem, em média, 2,46 vezes maior risco de desenvolver infecção na Unidade de Terapia Intensiva (IC95% 1,18; 5,11). Conclusão: O estudo oferece subsídios para padronização da técnica do banho no leito e prevenção de infecções relacionadas à assistência à saúde. Há limitação na generalização dos resultados, pois os grupos são oriundos de um delineamento quase experimental antes-depois com grupo controle não equivalente, devido à ausência de distribuição aleatória nos grupos comparados.

Occurrence of the bacteria in a hospital environment and their sensitivity profile to the main antimicrobials in a reference general hospital in Curitiba, Brazil / Ocorrência de bactérias em ambiente hospitalar, e seu perfil de sensibilidade aos principais antimicrobianos em um hospital de referência em Curitiba, Brasil / Ocurrencia de bacterias en ambiente hospitalario y su perfil de sensibilidad a los principales antimicrobianos en un hospital de referencia en Curitiba, Brasil

Introduction: Antimicrobial resistance rates are increasing in both hospital and community settings, creating a favorable environment for the development of superbacteria. Therefore, local studies are necessary for the proper management of current antimicrobial arsenals and for addressing the current bacteriological scenario. Aim: The aim of this study is to profile bacterial epidemiology in a hospital in Curitiba, Brazil and associate it with the effectiveness of antimicrobial therapy. Methodology: Data from 2019 to 2021 were collected by the Center for Epidemiology and Hospital Infection Control (CEHIC), and this was a quantitative single-center study. Results: The most commonly detected microorganisms were Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Staphylococcus epidermidis, Pseudomonas aeruginosa, Enterococcus faecalis, Acinetobacter baumannii, Staphylococcus haemolyticus, Staphylococcus hominis, and Enterobacter cloacae. A. baumannii and K. pneumoniae had the lowest mean sensitivity coefficients, while S. aureus was the most sensitive. Erythromycin was the least effective antimicrobial agent, while daptomycin was the most effective. Conclusion: These results are consistent with the literature and can be used to optimize empiric therapies, as there are already important therapeutic failures associated with antimicrobial resistance.

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.

Changing Escherichia coli susceptibility and increasing antimicrobial resistance in community urinary tract infections

Introducción: Las infecciones del tracto urinario causadas por bacterias gramnegativas resistentes a los antibióticos son una preocupación creciente debido a las limitadas opciones terapéuticas. Objetivo: Analizar la tendencia de resistencia a los antibióticos en Escherichia coli resistente a la ciprofloxacina aislada de la infección del tracto urinario adquirida en la comunidad. Métodos: Estudio de series de tiempo que analiza registros de urocultivos positivos para E. coli resistente a ciprofloxacina en personas de ≥18 años de 2011 a 2017. Las tendencias en los patrones de resistencia a los antibióticos se obtuvieron mediante la regresión lineal generalizada de Prais-Winsten. El cambio porcentual anual (APC) y el intervalo de confianza del 95 por ciento (IC 95 por ciento) se calcularon a partir del coeficiente de análisis de regresión β1 y el error estándar (SE). Los valores de p < 0,05 se consideraron estadísticamente significativos. Resultados: De los datos analizados, 3363 (26,1 por ciento) fueron positivos para E. coli resistente a la ciprofloxacina. El aumento de E. coli resistente a la ciprofloxacina fue del 45,3 por ciento. Las mujeres sufrieron más infección por E. coli sensible a la ciprofloxacina (75,5 por ciento), pero los hombres tuvieron una mayor probabilidad de infectarse con E. coli resistente a la ciprofloxacina [2,132 (1,891-2,402)]. El aumento de la resistencia fue mayor para la nitrofurantoína (<0,001) y la ceftriaxona (<0,001). La prevalencia de resistencia fue alta para nitrofurantoína, norfloxacina, ácido nalidíxico, amoxicilina/clavulanato, ceftriaxona y tobramicina. A excepción de la gentamicina, que presentó una tendencia a la baja en la resistencia, los otros antimicrobianos analizados no mostraron tendencias en la resistencia a los antibióticos. Conclusiones: Hubo un aumento promedio en la resistencia a los principales antibióticos utilizados para tratar la infecciones del tracto urinario adquirida en la comunidad. Entre los antibióticos probados, solo la gentamicina mostró una tendencia a la baja en la resistencia. Estos resultados son importantes para dirigir la elección de los antimicrobianos para el tratamiento empírico de la infección urinaria adquirida en la comunidad(AU)

Introduction: Urinary tract infections caused by antibiotic-resistant Gram-negative bacteria are a growing concern due to limited therapeutic options. Objective: To analyze the antibiotic resistance trend in ciprofloxacin-resistant Escherichia coli isolated from community-acquired urinary tract infection. Methods: Time series study analyzing records of urine cultures positive for ciprofloxacin-resistant E. coli in persons aged ≥18 years from 2011 to 2017. The trends in antibiotic resistance patterns were obtained using the Prais-Winsten generalized linear regression. Annual percent change (APC) and 95 percent confidence interval (CI 95 percent) were calculated from the regression analysis coefficient β1 and standard error (SE). Values of p<0.05 were considered statistically significant. Results: From the analyzed data, 3 363 (26.1 percent) were positive for ciprofloxacin-resistant E. coli. The increase in ciprofloxacin-resistant E. coli was 45.3 percent. Females suffered more infection by ciprofloxacin-sensitive E. coli (75.5 percent), but males had a higher chance of being infected with ciprofloxacin-resistant E. coli. [2.132 (1.891- 2.402)]. Increase in resistance was highest for nitrofurantoin (<0.001) and ceftriaxone (<0.001). Prevalence of resistance was high for nitrofurantoin, norfloxacin, nalidixic acid, amoxicillin/clavulanate, ceftriaxone, and tobramycin. Except for gentamicin, which presented a downward trend in resistance, the other antimicrobials analyzed displayed no trends in antibiotic resistance. Conclusions: There was an average increase in resistance to the main antibiotics used to treat community-acquired UTI. Among the antibiotics tested, only gentamicin displayed a downward trend in resistance. These results are important to direct the choice of antimicrobials for the empirical treatment of community-acquired UTI(AU)

Retrospective analysis of laboratory-acquired infection in China / 中国热带医学

@#Abstract: Objective To collect the cases of laboratory-acquired infections (LAI) reported in literatures in China, summarize the infection routes and causes of LAI in China, in order to improve laboratory staff's understanding of its occupational health and safety risks. Methods　The cases of laboratory-acquired infection reported in domestic literatures were collected from PubMed, CNKI, Wanfang Database, CBM China Biomedical Literature Database up to April 11, 2022, retrospectively analyze the number and causes of LAI reports, the main risk factors of LAI and its harm to society, the consequences of LAI or the leakage of pathogenic microorganisms, and put forward the relevant countermeasures of biological safety. Results　A total of 22 LAI reports were collected, reviewed and integrated into 21 reports. There were 7 kinds of pathogenic microorganisms. The main pathogenic microorganisms were hantavirus (42.86%, n=9) and Brucella (33.33%, n=7). There were 122 cases and 3 deaths in the laboratory. Most of the reports came from research laboratories (66.67%, n=14). The main route of infection was inhalation of aerosol (42.86%, n=9), followed by transdermal route (38.09%, n=8). Conclusions Failure to report LAI events will increase the risk of pathogenic microorganisms spreading to people outside the laboratory and the environment through infected laboratory staff. Local health institutions and laboratories should be encouraged to report LAI cases as a powerful tool for monitoring accidental leakage of pathogenic microorganisms and further improving laboratory biosafety. The laboratory needs strong biosafety measures to protect staff's health and prevent environmental pollution caused by accidental leakage of pathogenic microorganisms.

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.

Ubicación intrahospitalaria y tratamiento antimicrobiano inicial en pacientes con neumonía adquirida en la comunidad y su relación con la frecuencia y calidad del proceso de estratificación / Intrahospitalary location and antimicrobial initial treatment in patients with acquired pneumonia in the community and their relationship with the frequency and quality of the stratification process

La importancia de la evaluación inicial de la gravedad del paciente con neumonía es una acción diagnóstica de importancia bien establecida. El objetivo del trabajo fue evaluar la relación entre la frecuencia y calidad del proceso de estratificación de pacientes con neumonía, y el cumplimiento de las sugerencias de ubicación intrahospitalaria y de tratamiento antimicrobiano inicial de un instrumento de estratificación. Se realizó un estudio descriptivo sobre una población de 1,809 pacientes hospitalizados durante 10 años. Se analizó el comportamiento de los índices de ubicación intrahospitalaria y tratamiento antimicrobiano inicial acorde a la sugerencia de un instrumento de estratificación utilizado; en el análisis estadístico se utilizó el Odds ratio y el estadígrafo X2, con un nivel de significación de 95%. En los resultados se destacan que la ubicación intrahospitalaria estuvo acorde a la sugerencia del instrumento en el 96%, con el valor más bajo en los pacientes con neumonía grave y altas probabilidades de recuperación (82%, p<,05). Se constató mayor frecuencia de ubicación intrahospitalaria acorde a la sugerencia del instrumento en los pacientes bien estratificados (p<,05), fundamentalmente en los pacientes con neumonía grave y altas probabilidades de recuperación. La correspondencia del tratamiento antimicrobiano inicial con la propuesta del instrumento fue del 61%; el estrato IIIA mostró el valor más elevado (80%, p<,05). Como conclusiones del estudio se constató un elevado desempeño en el cumplimiento de la sugerencia de ubicación intrahospitalaria del instrumento de estratificación, no así en el cumplimiento de la sugerencia de tratamiento antimicrobiano inicial. Se demostró la existencia de una relación entre el proceso de estratificación y el cumplimiento de la ubicación intrahospitalaria sugerida por el instrumento empleado.

The initial evaluation of the patient's condition with pneumonia is a very important assistance action. The objective was evaluate the relationship between the frequency and quality of the stratification process of the patient with pneumonia, and the execution of suggestions of intrahospitalary location and the initial antimicrobial treatment of stratification instrument. A descriptive study was done on a population of 1,809 patients hospitalized during 10 years. The indexes of intrahospitalary location and of antimicrobian initial treatment were analized according to the suggestions of the instrument; in the statistical analysis it was used the odds ratio and the statistician X2, with a significant level of 95%. The intrahospitalary location was in agreement with the suggestion of the instrument in 96% of the cases, with the lowest value in patients with serious pneumonia and high recovery probabilities (82%, p <,05). The frequency of intrahospitalary location was bigger and veryfied with the suggestion of the instrument in the termed well stratified patients (p <,05), fundamentally in the patients with serious pneumonia and high recovery probabilities. The correspondence of the initial antimicrobial treatment with the proposal of the instrument was of 61%; the stratum IIIA showed the highest value (80%, p <,05). As conclusions, a high performance in the execution of the suggestion of the intrahospitalary location has been one of the characteristics of the process, although as a negative element it stands out the frequent non-fulfillment of the suggestion of the initial antimicrobial treatment. There was a relationship between the stratification process and the execution of the suggestion of the intrahospitalary location.

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.

Resistencia inducible a clindamicina en Staphylococcus aureus resistentes a meticilina aislados de pacientes pediátricos en Paraguay / Inducible resistance to clindamycin in methicillin-resistant Staphylococcus aureus isolated from Paraguayan children

Resumen Introducción: El método de difusión de doble disco se presenta como una alternativa diagnóstica que permite identificar aislados de Staphylococcus aureus susceptibles a clindamicina, ante el aumento de resistencia a meticilina, reduciendo así la posibilidad de fallo en el tratamiento. Objetivo: Determinar la frecuencia de resistencia a clindamicina inducida por eritromicina en S. aureus resistentes a meticilina (SARM) aislados de niños paraguayos. Materiales y Métodos: Estudio observacional, descriptivo, de corte transversal. Se colectaron 145 aislados S. aureus que causaron infecciones de piel y tejidos blandos y osteo-articulares en pacientes pediátricos del Hospital Central del Instituto de Previsión Social en el período de diciembre-2012 a noviembre-2013. La resistencia a clindamicina se determinó por métodos automatizados y de difusión de doble disco. Se realizó reacción de polimerasa en cadena para genes ermA, ermB, ermC y msrA de aislados representativos. Resultados: La resistencia global a meticilina y clindamicina fue de 67 y 13%, respectivamente (11% atribuible al mecanismo de resistencia a clindamicina inducible). Los genes ermC y msrA fueron detectados individualmente en 25 y 17% de los aislados, respectivamente, mientras que un aislado presentó ambos genes en simultáneo. Discusión: La frecuencia de mecanismo de resistencia inducible a clindamicina señala la importancia de los métodos de difusión de doble disco en la práctica microbiológica, así como se encuentran en los límites de puntos de cortes considerados como aceptables para el uso de este antimicrobiano para infecciones cutáneas y osteo-articulares causadas por SARM.

Background: The double disc diffusion method is an alternative diagnostic that allows the identification of Staphylococcus aureus isolates apparently susceptible to clindamycin but that may develop resistance due to an induction phenomena, mainly asociated to the increase in resistance to methicillin, thus increasing the possibility of failure in the treatment. Aim: To determine the frequency of induced clindamycin resistance in methicillin-resistant S. aureus (MRSA) isolated from Paraguayan children. Materials and Methods: In this cross sectional study, we collected 145 S. aureus isolates that caused skin and soft tissue and osteoarticular infections in pediatric patients of the Central Hospital I.P.S. in the period from December-2012 to November-2013. Resistance to clindamycin was determined by automated methods and double disc diffusion. PCR was performed for ermA, ermB, ermC and msrA genes from representative isolates. Results: The global resistance to methicillin and clindamycin was 67 and 13%, respectively (11% attributable to the inducible mechanism). The ermC and msrA genes were detected individually in 25 and 17% of the isolates respectively while an isolate presented both genes simultaneously. Discussion: The frequency of inducible resistance to clindamycin indicates the importance of double disc diffusion methods in microbiological practice, as well as being within the cut off points considered acceptable for the use of this antibiotic for skin infections. and osteoarticular caused by MRSA.

Objective To understand the clinical and pathogen characteristics of community acquired bloodstream infection(CABSI)for improving empirical antimicrobial therapy. Methods The clinical and laboratory findings of 193 CABSI cases in the Fifth Affiliated(Zhuhai)Hospital of Zunyi Medical College from 2013 to 2017 were retrospectively analyzed. Results Of the193 CABSI cases, 97.9％(189/193)had underlying diseases and/or risk factors. Primary site of infection was identified in 81.3％(157/193)of the patients. The top three primary site of infection was urinary tract(39.5％, 62/157), hepatobiliary system(22.9％, 36/157)and lower respiratory tract(20.4％, 32/157). The top pathogens included Escherichia coli(47.2％), Klebsiella pneumoniae(15.0％), coagulase-negative Staphylococcus(10.4％), and Streptococcus spp.(7.8％). All the E. coli and K. pneumoniae strains were susceptible to carbapenems. More than 90％ of the E. coli and K. pneumoniae strains were susceptible to piperacillin-tazobactam and amikacin. About 54.9％(50/91)of the E. coli and 27.6％(8/29)of the K. pneumoniae strains produced extended-spectrum β-lactamases(ESBLs). No vancomycin-resistant gram-positive bacteria were detected. The prevalence of MRCNS and MRSA was 35.0％ and 0, respectively. Conclusions Most CABSI cases had underlying diseases and/or risk factors. The common primary site of infection associated with secondary bloodstream infection is urinary tract, hepatobiliary system, and lower respirtaory tract. Enterobacteriaceae strains are the main pathogen of CABSI.

Healthcare-associated infection and community-acquired infection: Cross-sectional survey of 37 hospitals in Tangshan / 实用医学杂志

Objective To understand the status and the risk factors of healthcare-associated infection (HAI) and community-acquired infection (CAI) , and to provide guidance and basis for prevention and control of nosocomial infections. Methods We investigated and analyzed HAI and CAI of 37 hospitals by the cross-sectional survey method. Results 16 650 patients were investigated, the HAI occurred in 171 and 267 ases with the prevalence rate of 1.54％ and 5.24％ in the second-class and the third-class hospitals. The CAI occurred in 1 889 and 831 cases with the prevalence rate of 17.04％ and 16.31％. HAI prevalence rate in the third-class hospitals was higher than the second-class hospitals, while there was no difference in the rate of CAI. There was statistical significance in constituent of infection sites in different levels of hospitals. There was no difference in community infection. A total of 148 pathogens were isolated from patients with HAI, and the top four bacteria were Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia, Acinetobacter baumannii. The detection rate of multidrug-resistant bacteria were 26.32％ and 31.82％ respectively in the second-class and the third-class hospitals. The utilization rates of antimicrobial agents in the second-class and the third-class hospitals were 42.97％ and 31.82％ respectively. Pathogen detection rate in third-class hospitals was higher than that of the second-class hospitals (47.10％, 32.76％) , and the difference was statistically significant. The survey was found that the use of catheters, urinary tract catheters, ventilators and immunosuppressive agents were risk factors in hospital infection. Conclusion Hospitals should strengthen the monitoring of hospital infection and take various measures to control the rate of hospital infection.
