Implementación de un programa basado en IPASS en UCI / Implementation of an IPASS-based program in the ICU

Introducción: El uso de herramientas estandarizadas como estrategia de comunicación para brindar información relevante, precisa y actualizada, forma parte de las iniciativas de calidad en las instituciones que cumplen altos estándares en la atención de pacientes. Objetivo: Describir la implementación de un programa de traspaso (IPASS) en unidades de cuidados intensivos pediátricos específicos. Material y métodos: Estudio cuasi-experimental antes y después de una intervención, no controlado, utilizando como sujetos a los profesionales de la salud involucrados en traspasos de pacientes de la unidad de terapia intensiva cardiovascular (UCI 35) e inmunosuprimidos (UCI 72). La intervención consistió en la introducción de un paquete de medidas de estandarización del traspaso de pacientes que consta de: una herramienta escrita, una mnemotecnia oral, una capacitación de trabajo en equipo, observación y devolución estandarizada de los traspasos, basados en la metodología IPASS. Se realizó además una encuesta de percepción de seguridad, tanto en la etapa pre y post intervención. Se comparó el cumplimiento de cada componente del traspaso antes y después de la intervención mediante la prueba de chi2 . Resultados: Se realizaron 101 observaciones de traspaso y 56 encuestas. La mediana de pacientes por cada observación fue 6 (r: 4 a 12) y el tiempo promedio de 26± 11 min. Conclusiones: El uso de un paquete de medidas de estandarización del traspaso de pacientes posquirúrgicos cardiovasculares e inmunosuprimidos aumentó significativamente la presencia de información clave sobre criticidad de la enfermedad, acciones y situaciones de contingencia, junto con la inclusión de la síntesis por el receptor del traspaso (AU)

Introduction: The use of standardized tools as a communication strategy to provide relevant, accurate, and up-to-date information is part of quality initiatives in institutions that adhere to high standards in patient care. Objective: To describe the implementation of a handoff program (IPASS) in specific pediatric intensive care units. Methods: An uncontrolled, quasi-experimental, beforeand-after study. Subjects were healthcare providers involved in patient handoffs in the cardiovascular (ICU 35) and immunocompromised-patient (ICU 72) intensive care units. The intervention consisted of the introduction of a bundle to standardize patient handoff consisting of: a written tool, an oral mnemonic, teamwork training, observation, and standardized feedback for handoffs based on the IPASS methodology. A safety perception survey was also carried out, both in the pre- and post-intervention stage. Compliance with each handoff component before and after the intervention was compared using the Chi-squared test. Results: 101 handoff observations and 56 surveys were conducted. The median number of patients per observation was 6 (r: 4 to 12) and the mean handoff time was 26±11 min. Conclusions: The use of a standardized handoff bundle for post-surgical cardiovascular and immunocompromised patients significantly increased the availability of key information on disease severity, actions, and contingency situations, as well as a synthesis by the handoff receiver (AU)

Use of impregnated catheters to decrease colonization rates in neonates - A randomized controlled pilot trial.

OBJECTIVE: Nosocomial infections increase mortality and morbidity in preterm infants. Central venous line colonization is a major risk factor for the development of such infections. In adults and children, antibiotic and antimycotic impregnated catheters have been demonstrated to reduce colonization. However, recently published data showed no significant difference in bloodstream infection in neonates when an impregnated catheter was used. We investigated the effect of impregnation of percutaneously inserted micro-catheters (PICC) on colonization in preterm and sick term infants in our unit. METHODS: Neonates were randomly assigned to receive either a standard (S-PICC; n = 34) or antibiotic and antimycotic impregnated (IP-PICC; n = 37) PICC. Catheters were placed and removed according to a standard procedure and subsequently examined by roll-out culture. The primary outcome was the rate of colonization defined as >15 colony-forming-units/ml. Additional outcomes were catheter associated or systemic infections. RESULTS: The rate of colonization was lower in neonates who received an IP-PICC as compared to S-PICC (5.6% vs. 12.1% respectively; p = 0.42). However, the difference was not significant. In IP-PICC vs S-PICC, catheter related local infection (CRI) although lower was not statistically significant (2.9% vs. 6.1%; p = 0.60). We observed no difference in catheter related systemic infection (CR-SI) (0% vs. 3.1%, p = 0.48). The neonates whose catheters were colonized were predominantly of a lower gestational age (median 254/7, p = 0.05) and males (100%, p = 0.01). In addition, the median colony count in the colonized IP-PICC catheters was lower as compared to S- PICC group (53 vs 250, p = 0.06). CONCLUSIONS: The use of antibiotic and antimycotic impregnated PICC-lines in neonates tended to decrease colonization rates in neonates in our centers but this difference was not significant. Lower gestational age and male sex are risk factors for catheter colonization.

Reproductive and post-reproductive life history of wild-caught Drosophila melanogaster under laboratory conditions.

The life history of the fruit fly (Drosophila melanogaster) is well understood, but fitness components are rarely measured by following single individuals over their lifetime, thereby limiting insights into lifetime reproductive success, reproductive senescence and post-reproductive lifespan. Moreover, most studies have examined long-established laboratory strains rather than freshly caught individuals and may thus be confounded by adaptation to laboratory culture, inbreeding or mutation accumulation. Here, we have followed the life histories of individual females from three recently caught, non-laboratory-adapted wild populations of D. melanogaster. Populations varied in a number of life-history traits, including ovariole number, fecundity, hatchability and lifespan. To describe individual patterns of age-specific fecundity, we developed a new model that allowed us to distinguish four phases during a female's life: a phase of reproductive maturation, followed by a period of linear and then exponential decline in fecundity and, finally, a post-ovipository period. Individual females exhibited clear-cut fecundity peaks, which contrasts with previous analyses, and post-peak levels of fecundity declined independently of how long females lived. Notably, females had a pronounced post-reproductive lifespan, which on average made up 40% of total lifespan. Post-reproductive lifespan did not differ among populations and was not correlated with reproductive fitness components, supporting the hypothesis that this period is a highly variable, random 'add-on' at the end of reproductive life rather than a correlate of selection on reproductive fitness. Most life-history traits were positively correlated, a pattern that might be due to genotype by environment interactions when wild flies are brought into a novel laboratory environment but that is unlikely explained by inbreeding or positive mutational covariance caused by mutation accumulation.
