Detection of adverse events in general surgery using the " Trigger Tool" methodology.

INTRODUCTION: Surgery is one of the high-risk areas for the occurrence of adverse events (AE). The purpose of this study is to know the percentage of hospitalisation-related AE that are detected by the «Global Trigger Tool¼ methodology in surgical patients, their characteristics and the tool validity. MATERIAL AND METHODS: Retrospective, observational study on patients admitted to a general surgery department, who underwent a surgical operation in a third level hospital during the year 2012. The identification of AE was carried out by patient record review using an adaptation of «Global Trigger Tool¼ methodology. Once an AE was identified, a harm category was assigned, including the grade in which the AE could have been avoided and its relation with the surgical procedure. RESULTS: The prevalence of AE was 36,8%. There were 0,5 AE per patient. 56,2% were deemed preventable. 69,3% were directly related to the surgical procedure. The tool had a sensitivity of 86% and a specificity of 93,6%. The positive predictive value was 89% and the negative predictive value 92%. CONCLUSIONS: Prevalence of AE is greater than the estimate of other studies. In most cases the AE detected were related to the surgical procedure and more than half were also preventable. The adapted «Global Trigger Tool¼ methodology has demonstrated to be highly effective and efficient for detecting AE in surgical patients, identifying all the serious AE with few false negative results.

Multicentre cohort study of acute cholecystitis management during the COVID-19 pandemic.

PURPOSE: To analyse acute cholecystitis (AC) management during the first pandemic outbreak after the recommendations given by the surgical societies estimating: morbidity, length of hospital stay, mortality and hospital-acquired SARS-CoV-2 infection rate. METHODS: Multicentre-combined (retrospective-prospective) cohort study with AC patients in the Community of Madrid between 1st March and 30th May 2020. 257 AC patients were involved in 16 public hospital. Multivariant binomial logistic regression (MBLR) was applied to mortality. RESULTS: Of COVID-19 patients, 30 were diagnosed at admission and 12 patients were diagnosed during de admission or 30 days after discharge. In non-COVID-19 patients, antibiotic therapy was received in 61.3% of grade I AC and 40.6% of grade II AC. 52.4% of grade III AC were treated with percutaneous drainage (PD). Median hospital stay was 5 [3-8] days, which was higher in the non-surgical treatment group with 7.51 days (p < 0.001) and a 3.25% of mortality rate (p < 0.21). 93.3% of patients with SARS-CoV-2 infection at admission were treated with non-surgical treatment (p = 0.03), median hospital stay was 11.0 [7.5-27.5] days (p < 0.001) with a 7.5% of mortality rate (p > 0.05). In patients with hospital-acquired SARS-CoV-2 infection, 91.7% of grade I-II AC were treated with non-surgical treatment (p = 0.037), with a median hospital stay of 16 [4-21] days and a 18.2% mortality rate (p > 0.05). Hospital-acquired infection risk when hospital stay is > 7 days is OR 4.7, CI 95% (1.3-16.6), p = 0.009. COVID-19 mortality rate was 11.9%, AC severity adjusted OR 5.64 (CI 95% 1.417-22.64). In MBLR analysis, age (OR 1.15, CI 95% 1.02-1.31), SARS-CoV-2 infection (OR 14.49, CI 95% 1.33-157.81), conservative treatment failure (OR 8.2, CI 95% 1.34-50.49) and AC severity were associated with an increased odd of mortality. CONCLUSION: In our population, during COVID-19 pandemic, there was an increase of non-surgical treatment which was accompanied by an increase of conservative treatment failure, morbidity and hospital stay length which may have led to an increased risk hospital-acquired SARS-CoV-2 infection. Age, SARS-CoV-2 infection, AC severity and conservative treatment failure were mortality risk factors.

Perforación intestinal por citomegalovirus durante un Síndrome de Reconstitución Inmune / Intestinal Perforation for Cytomegalovirus in Immune Reconstitution Syndrome

RESUMEN El síndrome de reconstitución inmune se produce debido a un aumento de la inmunocompetencia en pacientes previamente inmunocomprometidos. La situación es frecuente tras iniciar un tratamiento antirretroviral de alta eficacia, en pacientes con infección por el virus de inmunodeficiencia humana. En determinados casos, puede conllevar un empeoramiento paradójico de una infección previa. El citomegalovirus, es un germen oportunista que, en el seno de un síndrome de reconstitución inmune, puede dar lugar a perforación intestinal multifocal y peritonitis secundaria de difícil tratamiento. Es más frecuente en pacientes con recuento de linfocitos cooperadores inferior a 50 células/mm3 al iniciar el tratamiento antirretroviral. El objetivo es comunicar dicha situación a través, de un caso clínico para facilitar su sospecha lo más pronto posible, y realizar un tratamiento adecuado. Presentamos el caso de un paciente con virus de inmunideficiencia humana de reciente diagnóstico, en tratamiento con terapia antirretroviral de alta eficacia, que acude a urgencias con abdomen agudo secundario a perforación por citomegalovirus. La infección conlleva importante morbimortalidad, siendo imprescindible un diagnóstico temprano e iniciar precozmente el tratamiento antiviral intravenoso, asociado generalmente a tratamiento quirúrgico(AU)

ABSTRACT Immune reconstitution syndrome occurs due to increased immunocompetence in previously immunocompetent patients. The condition is frequent in patients with human immunodeficiency virus infection who have started a highly active antiretroviral therapy. In certain cases, the syndrome can lead to a paradoxical worsening of a previous infection. Cytomegalovirus is an opportunistic germ that, during an immune reconstitution syndrome, can lead to multifocal intestinal perforation and secondary peritonitis, in cases that are difficult to treat. The syndrome is more frequent in patients with CD4 lymphocyte count below 50/mm3 at the time of starting antiretroviral treatment. The objective is to communicate this situation through a clinical case presentation in order to facilitate suspicion as soon as possible, and to carry out appropriate treatment. We present the case of a patient with a recently diagnosed human immunodeficiency virus, under treatment with highly active antiretroviral therapy, who attended the emergency department with an acute abdomen secondary to perforation due to cytomegalovirus. Infection carries significant morbidity and mortality, and early diagnosis is essential and intravenous antiviral treatment should be started early, generally associated with surgical treatment(AU)

Detección de efectos adversos en cirugía general mediante la aplicación de la metodología «Trigger Tool» / Detection of adverse events in general surgery using the « Trigger Tool» methodology

INTRODUCCIÓN: La cirugía supone una de las áreas de alto riesgo para la aparición de efectos adversos (EA). El objetivo de este estudio es conocer el porcentaje de EA en hospitalización que se detectan mediante la metodología «Global Trigger Tool» en pacientes de cirugía general, las características de los mismos y la validez de la herramienta. MATERIAL Y MÉTODOS: Estudio retrospectivo, observacional y descriptivo sobre pacientes ingresados en cirugía general de un hospital de tercer nivel, sometidos a intervención quirúrgica durante el año 2012. La identificación de EA se lleva a cabo mediante una revisión de historias clínicas empleando una adaptación de la metodología «Global Trigger Tool» Una vez identificado el EA, se le asignó una categoría de daño y se determinó el grado en el que este podría haber sido evitado así como su relación con el procedimiento quirúrgico. RESULTADOS: La prevalencia de EA fue de 36,8%. Con un número de EA por paciente de 0,5. El 56,2% se consideraron evitables. Y un 69,3% se relacionaron directamente con el procedimiento quirúrgico. La herramienta demostró una sensibilidad del 86% y una especificidad del 93,6%. El valor predictivo positivo fue de 89%, el valor predictivo negativo de 92%. CONCLUSIONES: La prevalencia de EA es más alta de lo estimado en otros estudios. La mayoría de los EA detectados están relacionados con el procedimiento quirúrgico, y más de la mitad son evitables. La metodología «Global Trigger Tool» adaptada ha demostrado ser altamente eficaz y eficiente para la detección de EA en cirugía, identificando todos los EA graves y con pocos falsos negativos
