Funduplicatura con disección extensa de la unión esofagogástrica: lecciones aprendidas y resultados tras 178 pacientes consecutivos / Fundoplication with extensive dissection of the esophagogastric junction: Lessons learned and outcomes from 178 consecutives patients

Introducción: La cirugía antirreflujo se asocia con frecuencia a tasas significativas de recurrencia y complicaciones, habiéndose propuesto varias técnicas quirúrgicas para minimizarlas. El objetivo del estudio es evaluar los resultados a tres años de una funduplicatura con disección extensa de la unión esofagogástrica (UEG). Métodos: Estudio observacional retrospectivo que incluyó a 178 pacientes con enfermedad por reflujo gastroesofágico (ERGE) o hernia de hiato (HH) a los que se les realizó una funduplicatura con disección extensa de la UEG entre 2015 y 2020. La recidiva herniaria, los síntomas y la calidad de vida al primer año y a los tres siguientes de la cirugía fueron evaluados mediante tránsito baritado, endoscopia y cuestionarios para síntomas y calidad de vida (Gastro Esophageal Reflux Disease-Health Related Quality of Life [GERD-HRQL]). Resultados: La tasa de pirosis fue de 7,5 y 10,7% al año y a los tres siguientes, respectivamente, regurgitación de 3,8 y 6,9% y disfagia de 3,7 y 7,6%. La presencia de hernia hiatal se evidenció preoperatoriamente en 55,1% y en 7,8 y 9,6% en el seguimiento y la mediana de la escala GERD-HRQL fue de 27, 2 y 0, respectivamente. No aparecieron casos de telescopaje de la funduplicatura ni síntomas que sugieran lesión vagal. No se encontraron diferencias al comparar los distintos tipos de funduplicatura en términos de recidiva del reflujo, complicaciones o recurrencia de la hernia. Conclusiones: La funduplicatura con disección extensa de la UEG contribuye a su correcto posicionamiento y mejor anclaje, lo que asocia bajas tasas de recidiva herniaria y del reflujo, así como disminuye la posibilidad de telescopaje y lesión vagal.(AU)

Introduction: Antireflux surgery is commonly associated with significant recurrence and complication rates, and several surgical techniques have been proposed to minimize them. The aim of this study is to evaluate the results of a fundoplication with extensive dissection of the esophagogastric junction 1 and 3 years after the procedure.Methods: Retrospective observational study including 178 patients with gastroesophageal reflux disease or hiatal hernia who underwent fundoplication with extensive dissection of the esophagogastric junction between 2015 and 2020. Hernia recurrence, symptoms and quality of life at 1 and 3 years after surgery were assessed by barium transit, endoscopy and questionnaires for symptoms and quality of life (GERD-HRQL). Results: Heartburn rate was 7.5% and 10.7% at 1 and 3 years respectively, regurgitation 3.8% and 6.9% and dysphagia was 3.7% and 7.6%. The presence of hiatal hernia was evident preoperatively in 55.1% and in 7.8% and 9.6% at follow-up and the median GERD-HRQL scale was 27, 2 and 0, respectively. There were no cases of slippage of the fundoplication or symptoms suggestive of vagal injury. No differences were found when comparing the different types of fundoplication in terms of reflux and recurrence or complications. Conclusions: Fundoplication with extensive dissection of the esophagogastric junction contributes to correct positioning and better anchorage of the fundoplication, which is associated with low rates of hiatal hernia and reflux recurrence, as well as absence of slippage and lower possibility of vagal injury.(AU)

Using artificial intelligence to reduce orthopedic surgical site infection surveillance workload: Algorithm design, validation, and implementation in 4 Spanish hospitals.

BACKGROUND: Surgical site infection (SSI) surveillance is a labor-intensive endeavor. We present the design and validation of an algorithm for SSI detection after hip replacement surgery, and a report of its successful implementation in 4 public hospitals in Madrid, Spain. METHODS: We designed a multivariable algorithm, AI-HPRO, using natural language processing (NLP) and extreme gradient boosting to screen for SSI in patients undergoing hip replacement surgery. The development and validation cohorts included data from 19,661 health care episodes from 4 hospitals in Madrid, Spain. RESULTS: Positive microbiological cultures, the text variable "infection", and prescription of clindamycin were strong markers of SSI. Statistical analysis of the final model indicated high sensitivity (99.18%) and specificity (91.01%) with an F1-score of 0.32, AUC of 0.989, accuracy of 91.27%, and negative predictive value of 99.98%. DISCUSSION: Implementation of the AI-HPRO algorithm reduced the surveillance time from 975 person/hours to 63.5 person/hours and permitted an 88.95% reduction in the total volume of clinical records to be reviewed manually. The model presents a higher negative predictive value (99.98%) than algorithms relying on NLP alone (94%) or NLP and logistic regression (97%). CONCLUSIONS: This is the first report of an algorithm combining NLP and extreme gradient-boosting to permit accurate, real-time orthopedic SSI surveillance.

Impact of sink removal from intensive care unit rooms on the consumption of antibiotics and on results of Zero Resistance Project

IntroductionDue to the favourable impact of removing the sinks on isolations in bronchoaspirate samples of patients with mechanical ventilation, we now evaluate the impact on the consumption of antibiotics as well as on the results of the Zero Resistance Project (ZRP).Patients and methodsAll the patients admitted to the unit in a quasi-experimental before–after study with a pre-intervention period between 2014 and 2016 and a post-intervention period from 2016 to 2017, to evaluate antibiotic consumption in defined daily doses, and until 2018, to evaluate the ZRP indicators. The intervention was the removal of the sinks from the rooms of the ICU. We evaluated antibiotic consumption densities and their ratios, grouped as Enterobacteriaceae and non-fermenting gram-negative bacilli (NFGNB) according to their antibiograms; the absolute number of ‘antibiotic days’, ‘hospitalised days’, ‘isolation days’, and ‘multi-resistant bacteria (MRB) days’; as well as their incidence densities per 1000 hospitalised days and the ratio between the two years prior to and the two years after the intervention.ResultsPost-intervention antibiotic use was 1.61-fold (1.60–1.62) and 2.24-fold (2.10–2.37) lower for antibiotics used against Enterobacteriaceae and NFGNB, respectively. There were also reductions in the number of days of antibiotic use by 1.29-fold (1.22–1.36), number of MRB days by 1.84-fold (1.63–2.08), and number of patient isolation days by 1.51-fold (1.38–1.66).DiscussionThe results suggest that the intervention had a favourable impact on the consumption of antibiotics, as well as on the number of days on antibiotics, MRB, and isolation.

Costes asociados al diagnóstico y tratamiento quirúrgico del cáncer de mama precoz / Costs associated with the diagnosis and surgical procedure of early breast cancer

ObjetivoEl examen de los costes asociados al diagnóstico y tratamiento quirúrgico en un grupo de pacientes con cáncer de mama.MétodoAnálisis de costes referido a la valoración clínica preoperatoria, tipo de cirugía y hospitalización en una cohorte de 224 pacientes con cáncer de mama en estadios precoces, intervenidas desde junio-2012 a diciembre-2016.ResultadosLa cirugía conservadora en régimen de cirugía mayor ambulatoria versus hospitalización, aplicada a la tumorectomía con biopsia selectiva de ganglio centinela supuso un ahorro de 2.085 € por paciente, y total en nuestra serie de pacientes de 289.815 €. La aplicación del estudio ACOSOG (American College of Surgeons Oncology Group) a 18 pacientes con ganglio centinela positivo evitó la linfadenectomía axilar y redujo el coste en 37.530 €. La RMN preoperatoria en cáncer de mama aportó un beneficio en el tratamiento de 31 pacientes; una selección de pacientes más precisa habría supuesto un ahorro de 37.179 €. Las ampliaciones de márgenes quirúrgicos sin hallazgo de tumor residual determinaron un gasto de 11.592 €.Conclusiones-La cirugía conservadora de mama con biopsia selectiva de ganglio centinela en régimen de cirugía mayor ambulatoria supuso un ahorro importante de recursos sin comprometer el bienestar y pronóstico de las pacientes.-Los costes asociados a la realización de una RMN preoperatoria sin selección previa de pacientes y las reintervenciones de ampliación de márgenes determinaron un gasto evitable en buena parte de las pacientes.(AU)

ObjectiveThe aim of our study was to identify the costs associated with the diagnosis and surgical procedure in a cohort of patients with early breast cancer.MethodWe performed a costs study, referred to the preoperatory radiological-histological study, surgical procedure and inpatient/outpatient health service in a cohort of 224 patients diagnosed and operated on early-stage breast from June 2012 to December 2016.ResultsBreast conserving surgery in outpatient health service applied to lumpectomy with sentinel lymph node biopsy compared to carrying it out in the inpatient setting, contributed to a saving of 2085€ per patient, and total of 289,815€. Following the ACOSOG (American College of Surgeons Oncology Group) trial in 18 patients with tumor-involved sentinel node, no further axillary specific treatment (completion of lymphadenectomy) was made, allowing a saving of 37,530€. In most patients our study have not showed benefit from diagnostic/preoperative breast MRI, leading to an over cost of 37,179€. The surgical rescission without showing the presence of residual tumor burden, led to an additional cost of 11,592€.Conclusions-Breast conserving surgery with sentinel lymph node biopsy in outpatient health service supposed an important economical saving of resources, without compromising the well-being and prognosis of our patients.-The diagnostic/preoperative MRI in all the patients and the surgical rescissions led to an over cost that could be avoided in most of the cases.(AU)

Effectiveness and satisfaction in non-critical surface cleaning and disinfection using quaternary ammonium-based spray and wipe formats / Efectividad y satisfacción en la limpieza y desinfección de superficies no críticas utilizando amonio cuaternario en formatos de aerosol y toallitas húmedas

OBJECTIVE: To compare the effectiveness and satisfaction with the use of sprays and wipes formats under healthcare facilities conditions. METHODS: Randomized crossover experimental study in four hospitals in the Region of Madrid. A quaternary ammonium formula in spray and wipe formats in a crossover manner over two weeks in all the units. The effectiveness was evaluated by means of relative light unit (RLU). The variables of effectiveness, method of use and satisfaction were taken into account. RESULTS: Samples were taken from 162 surfaces and no differences were found after disinfection, 60.00 (17.00-148.00) RLU for sprays and 67.00 (36.00-139.00) RLU for wipes (p = 0.271). A wider range of uses and results was found for sprays. 70.96% of the staff (n = 93) preferred wipes over sprays. CONCLUSIONS: Being equally effective, disinfection with wipes generated greater satisfaction with less variety in the results than sprays

Preoperative intragastric balloon in morbid obesity is unable to decrease early postoperative morbidity of bariatric surgery (sleeve gastrectomy and gastric bypass): a clinical assay.

INTRODUCTION: There are few studies that investigate the usefulness of the preoperative intragastric balloon (IGB). This study will evaluate if pre-surgical weight loss with IGB reduces morbidity and mortality after surgery. METHOD: Prospective randomised study of patients with morbid obesity treated with gastric bypass or vertical gastrectomy, with two arms: the balloon arm (B-arm), where an IGB was inserted within the 6 months before surgery, and the control arm (C-arm). RESULTS: The study included 66 patients: 65.6% women, 69.6% with bypass. Age: 43 years (SD 10.2) B-arm and 42.6 years (SD 9.2) in the C-arm. We found 34.4% therapeutic failures in IGB. The mean body weight loss, %EWL and BMI reduction before surgery was 16.2 kg (SD 9.84) B-arm versus 4.7 (SD 8.70) in the C-arm, 23.6% versus 4.7% (p < 0.001) and 6.04 versus 1 (p < 0.001), respectively. The hospital stay was 7 days (p25-75: 5-8) B-arm and 7 days (p25-75: 5-9) in the C-arm (p = 0.937). Post-surgical morbidity with IGB was 25% versus 29.5% in the C-arm, p = 0.689. The number needed to treat (NNT) to prevent of post-surgical morbidity was 23 patients. The B-arm presented 54.5% moderate-severe post-surgical adverse events (12.5%) versus 82.6% in the C-arm (23.5%), p = 0.111. The cost of placing a balloon was more than 4000 Euros each. CONCLUSIONS: The preoperative balloon does not achieve a reduction in the post-surgical morbidity, nor does it reduce the hospital stay or rate of re-operations. The balloon achieves a higher weight loss result when compared to a diet programme, its added cost must also be given due consideration. TRAIL REGISTRY: This study has been registered on ClinicalTrials.gov with the Identifier: NCT01998243 (November 28, 2013).

Incidence of surgical site infection in dogs undergoing soft tissue surgery: risk factors and economic impact.

OBJECTIVES: To determine (1) the incidence of surgical site infection (SSI) in patients undergoing soft tissue surgery at a veterinary teaching hospital and to study (2) and describe the main risk factors associated with SSI and (3) assess the economic impact of SSI. DESIGN: Prospective cohort study. SETTING: Veterinary teaching hospital. PARTICIPANTS: 184 dogs undergoing soft tissue surgery during a 12-month period (October 2013 to September 2014). PRIMARY OUTCOME MEASURE: Surgical site infection. RESULTS: Out of the 184 patients analysed, SSI was diagnosed in 16 (8.7 per cent) patients, 13 (81.3 per cent) were classified as superficial incisional infection, 2 (12.5 per cent) as deep incisional infection and 1 (6.3 per cent) as organ/space infection. The administration of steroidal anti-inflammatory drugs (P=0.028), preoperative hyperglycaemia (P=0.015), surgical times longer than 60 minutes (P=0.013), urinary catheterisation (P=0.037) and wrong use of the Elizabethan collar (P=0.025) were identified as risk factors. Total costs increased 74.4 per cent, with an increase in postsurgical costs of 142.2 per cent. CONCLUSIONS: The incidence of SSI was higher than the incidence reported in other published studies, although they were within expected ranges when a surveillance system was implemented. This incidence correlated with an increase in costs. Additionally new important risk factors for its development were detected.

Precisión de la resonancia magnética, ecografía y mamografía en la medida del tamaño tumoral y su correlación con el tamaño histopatológico en el cáncer de mama primario / Accuracy of tumor size measurements performed by magnetic resonance, ultrasound and mammography, and their correlation with pathological size in primary breast cáncer

Introducción: El objetivo de este estudio fue evaluar qué prueba de imagen de las empleadas para medir el tamaño del cáncer de mama primario preoperatorio (mamografía, ecografía o resonancia magnética [RM]) se correlacionó mejor con el tamaño del tumor en la pieza quirúrgica postoperatoria. Métodos: Análisis retrospectivo de mujeres con diagnóstico de cáncer de mama y con indicación de tratamiento quirúrgico primario operadas desde enero del 2014 hasta diciembre del 2016. Se recogieron variables sociodemográficas, vinculadas a técnicas de imagen e histológicas. Los resultados se presentaron según edad, tamaño tumoral y tipo histológico. Resultados: Se estudió a 224 mujeres. Al comparar el tamaño mamográfico y de la RM con el histológico final no se encontraron diferencias significativas, tanto de forma global como teniendo en cuenta el grupo histológico o la edad, sin embargo, ambas infraestimaron significativamente los tumores grandes y sobrestimaron significativamente los pequeños. La ecografía infraestimó significativamente el tamaño del tumor, especialmente en tumores grandes, pacientes mayores y en los grupos de carcinoma ductal infiltrante (CDI) y CDI con carcinoma ductal in situ asociado (CDI + CDIS). La RM se correlacionó mejor con el tamaño tumoral histológico aunque sin diferencias estadísticamente significativas. Conclusiones: La RM parece ser el mejor predictor del tamaño del tumor en el cáncer de mama. El grupo histológico y el tamaño del tumor fueron claves en la estimación de la medida del tumor, por lo que se deben tener en cuenta en la planificación de la cirugía. La variable edad no interfirió en la interpretación de las imágenes

Introduction: The objective of this study was to determine which image test used to measure the size of pre-operative primary breast cancer (mammography, ultrasound or magnetic resonance imaging [MRI]) correlated best with the size of the tumor in the postoperative surgical specimen. Methods: A retrospective analysis was conducted of women diagnosed with breast cancer for which primary surgical treatment was indicated and who underwent surgical intervention between January 2014 and December 2016. Sociodemographic, imaging and histological variables were collected. The results are presented by age group, tumor size and histological type. Results: In the 224 women studied, mammography and MRI tumor sizes were compared with pathology study tumor measurements, revealing no significant differences, both overall and based on histologic type or age. However, both significantly underestimated large tumors and significantly overestimated small tumors. Ultrasound significantly underestimated tumor size, especially in large tumors, older patients and in infiltrating ductal carcinoma (IDC) and infiltrating ductal carcinoma with associated ductal carcinoma in situ (IDC + DCIS). MRI correlated best with histological tumor size, although with no statistically significant differences. Conclusions: MRI is the best predictor of tumor size in breast cancer. Histologic type and tumor size are key parameters when estimating tumor size and should be taken into account when planning surgery. Patient age does not interfere with the interpretation of imaging tests

La violencia interpersonal en España a través del Conjunto Mínimo Básico de Datos / Interpersonal violence in Spain through national hospital discharge survey

Objetivo: Describir la epidemiología de la violencia interpersonal en España. Método: Estudio descriptivo de los casos de pacientes con diagnóstico secundario de agresión registrados en el Conjunto Mínimo Básico de Datos de altas hospitalarias, entre 1999 y 2011, utilizando los códigos E960 a E969 de la Clasificación Internacional de Enfermedades (CIE-9). Se describe la distribución por sexo, edad y tipo de alta y de atención requerida, morbilidad asociada, mortalidad y comunidad autónoma. Se estudia la calidad del registro en función de su variación temporal. Resultados: El perfil de agresión en hombres (85%) es el de un paciente de entre 15 y 44 años, que en un 93,7% de los casos precisa atención urgente y cuya gravedad es moderada (95% alta a domicilio). El 2,5% de los pacientes reingresa, y se produce la muerte en el 1,1% de las ocasiones. El perfil en las mujeres (15%) difiere ligeramente: edad comprendida entre 31 y 52 años, el 94% requiere atención urgente (si bien el 96% tiene una gravedad moderada), el 3% reingresa y en el 1,7% de las ocasiones la paciente muere. Conclusiones: Aunque necesitan ser mejorados para evitar ciertas limitaciones, los sistemas de información sanitaria constituyen una riquísima fuente de datos que pueden ser utilizados para la investigación en salud y, a través de sus resultados, para el desarrollo de planes de prevención e intervención sociosanitaria en temas de violencia

Objective: To describe the epidemiology of interpersonal violence in Spain. Method: Descriptive study of the cases of patients with secondary diagnosis of aggression registered on a national hospital discharge database, between 1999 and 2011, using the codes from E960 to E969 of the ICD-9. The distribution by sex, age and type of discharge, associated morbidity, mortality and by autonomous community is described. The quality of the record is studied according to its temporal variation. Results: The case profile of aggression in men (85%) is of a patient between 15 and 44 years old, who in 93.7% of cases requires urgent care and whose severity is moderate (95% discharge home). Two point five percent of patients are readmitted and death occurs in1.1%. The profile in women (15%) differs slightly, with an age between 31 and 52 years, 94% require urgent attention, although 96% have moderate severity; 3% are readmitted and 1.7% die. Conclusions: Although they need to be improved to avoid certain limitations, health information systems are a rich source of data that can be used for research in health and, through their results, for the development of prevention plans and intervention in matters of violence

Impacto de la retirada de los lavabos en una unidad de cuidados intensivos sobre los aislamientos por bacilos gramnegativos no fermentadores en pacientes con ventilación mecánica invasiva / Impact of removing sinks from an intensive care unit on isolations by gram-negative non-fermenting bacilli in patients with invasive mechanical ventilation

Introducción y objetivo: La contaminación de los lavabos, incluso por su infrautilización, se asocia a la transmisión de bacilos gramnegativos no fermentadores (BGNNF) en unidades que atienden a pacientes con alto riesgo de infección. Tras vigilancia previa con muestras ambientales y de pacientes, se explora ahora el impacto de la retirada de los lavabos de los boxes de una UCI sobre aislamientos incidentes relacionados con la atención sanitaria en muestras de broncoaspirado de pacientes con ventilación mecánica invasiva (VMI). Material y métodos: Estudio cuasiexperimental antes-después, con anualidades preintervención y postintervención correspondientes a los períodos abril 2014-2016 y abril 2016-2017, respectivamente. Se estudiaron las densidades de incidencia por 1.000 días de VMI comparándose por el método exacto basado en la distribución binomial y estimándose la razón de densidades de incidencia. Resultados: Las densidades de incidencia por 1.000 días de VMI de aislamientos por BGNNF en las muestras de broncoaspirado de los períodos pre y postintervención fueron 11,28 y 1,91, respectivamente, lo que supone una densidad de incidencia postintervención 5,90 veces menor que la previa (IC95%: 1,49-51,05; p=0,003). Conclusiones: A pesar de las limitaciones del diseño, la retirada de los lavabos apunta a una reducción de los aislamientos

Introduction and objective: Contamination of sinks, even due to their underuse, is associated with the transmission of non-fermenting gram-negative bacilli (NFGNB) to patients in Augmented Care Units. After previous monitoring with environmental and patient samples, we now explore the impact of removing sinks from ICU cubicles on incidental isolations related to health care in bronchoaspirate samples of patients with invasive mechanical ventilation (IMV). Material and methods: Quasi-experimental study, before-and-after, pre-intervention annuities April 2014-2016 and post-intervention April 2016-2017. Incidence densities per 1,000 days of IMV were studied, comparing by the exact method based on the binomial distribution and estimating the incidence density ratio. Results: The incidence densities per 1,000 days of IMV of isolations by NFGNB in bronchoaspirate samples of the pre and post-intervention periods were 11.28 and 1.9, respectively. This implies a post-intervention incidence density 5.90 times lower than before (95% CI: 1.49-51.05, P=.003). Conclusions: Despite of the limitations of the design, the removal of sinks showed a reduction of the isolations

Impact of removing sinks from an intensive care unit on isolations by gram-negative non-fermenting bacilli in patients with invasive mechanical ventilation. / Impacto de la retirada de los lavabos en una unidad de cuidados intensivos sobre los aislamientos por bacilos gramnegativos no fermentadores en pacientes con ventilación mecánica invasiva.

INTRODUCTION AND OBJECTIVE: Contamination of sinks, even due to their underuse, is associated with the transmission of non-fermenting gram-negative bacilli (NFGNB) to patients in Augmented Care Units. After previous monitoring with environmental and patient samples, we now explore the impact of removing sinks from ICU cubicles on incidental isolations related to health care in bronchoaspirate samples of patients with invasive mechanical ventilation (IMV). MATERIAL AND METHODS: Quasi-experimental study, before-and-after, pre-intervention annuities April 2014-2016 and post-intervention April 2016-2017. Incidence densities per 1,000 days of IMV were studied, comparing by the exact method based on the binomial distribution and estimating the incidence density ratio. RESULTS: The incidence densities per 1,000 days of IMV of isolations by NFGNB in bronchoaspirate samples of the pre and post-intervention periods were 11.28 and 1.9, respectively. This implies a post-intervention incidence density 5.90 times lower than before (95% CI: 1.49-51.05, P=.003). CONCLUSIONS: Despite of the limitations of the design, the removal of sinks showed a reduction of the isolations.

[Interpersonal violence in Spain through national hospital discharge survey]. / La violencia interpersonal en España a través del Conjunto Mínimo Básico de Datos.

OBJECTIVE: To describe the epidemiology of interpersonal violence in Spain. METHOD: Descriptive study of the cases of patients with secondary diagnosis of aggression registered on a national hospital discharge database, between 1999 and 2011, using the codes from E960 to E969 of the ICD-9. The distribution by sex, age and type of discharge, associated morbidity, mortality and by autonomous community is described. The quality of the record is studied according to its temporal variation. RESULTS: The case profile of aggression in men (85%) is of a patient between 15 and 44 years old, who in 93.7% of cases requires urgent care and whose severity is moderate (95% discharge home). Two point five percent of patients are readmitted and death occurs in1.1%. The profile in women (15%) differs slightly, with an age between 31 and 52 years, 94% require urgent attention, although 96% have moderate severity; 3% are readmitted and 1.7% die. CONCLUSIONS: Although they need to be improved to avoid certain limitations, health information systems are a rich source of data that can be used for research in health and, through their results, for the development of prevention plans and intervention in matters of violence.

La infrautilización de grifos en una unidad de cuidados intensivos como causa de reservorios de bacilos gramnegativos no fermentadores / Under-utilization of taps in intensive care unit as a cause of reservoirs of nonfermenting gram-negative bacilli

INTRODUCCIÓN: La infrautilización de grifos se relaciona con reservorios de bacilos gramnegativos no fermentadores en su interior con capacidad de diseminación. Se describe la detección del problema y abordaje en una UCI. MÉTODOS: Estudio descriptivo en una UCI con boxes individuales con lavabo propio. Se recogieron muestras clínicas de pacientes y ambientales de los aireadores de los grifos. Se revisaron medidas de higiene. RESULTADOS: Se identificaron 4 casos de Chryseobacterium indologenes, uno de Elizabethkingia meningoseptica y otro por Pseudomonas aeruginosa, tanto en muestras clínicas como ambientales. Los profesionales indicaron utilizar solución hidroalcohólica casi siempre en la higiene de manos. Tras descartar la apertura controlada diaria de grifos por ineficiente, se decidió su retirada. CONCLUSIONES: Las recomendaciones nacionales resultaron insuficientes para la prevención, detección y control de la contaminación de los grifos de una unidad de alto riesgo de infección. Es necesario mejorar el manejo de los grifos en estas unidades

INTRODUCTION: The under-utilisation of taps is associated with the generation of reservoirs of non-fermenting gram-negative bacilli with the ability to disseminate. We describe the detection and approach of the problem in an ICU. METHODS: Observational descriptive study in an ICU with individual cubicles with their own sink. We collected clinical samples from patients and environmental samples from tap aerators and reviewed the unit's hygiene measures. RESULTS: We detected four cases due to Chryseobacterium indologenes, one to Elizabethkingia meningoseptica and another to Pseudomonas aeruginosa; they were identified both in clinical and the environmental samples. The healthcare professionals reported that almost every hand hygiene opportunity was performed with a hydroalcoholic solution. After considered the daily flushing of water outlets as inefficient, it was decided to remove them. CONCLUSIONS: National recommendations were insufficient for preventing, detecting and controlling tap contamination in units with a high risk of infection. The management of taps in these units needs to be improved
