Comparison of clinical outcomes of venous thromboembolic disease between outpatient and inpatient management.

Objectives: To compare the occurrence of death, bleeding, and recurrence according to inpatient or outpatient management of venous thromboembolic disease (VTE). Materials and methods: . Retrospective cohort that included a consecutive sampling of VTE consultations between 2016 and 2019 diagnosed in the Emergency Center of a private hospital in Argentina. Results: There were 1202 cases, 908 with isolated deep vein thrombosis (DVT), 205 with isolated pulmonary embolism (PE), and 89 cases of combined DVT - PE. 66% were women, with a median age of 77 years; 72% of cases were managed on an outpatient basis (n= 862). Comorbidities associated with hospitalization were obesity (p=0.03), chronic obstructive pulmonary disease (COPD) (p=0.01), heart failure (CHF) (p=0.01), chronic renal failure (CKD) (p=0.01), and cancer (p=0.01). At 90 days, the cumulative incidence of bleeding was 2.6% in inpatient compared to 2.9% in outpatient management (p=0.81); recurrence was 0% versus 0.9% (p=0.07), and mortality was 42.9% versus 18.9%, respectively (p=0.01). The HR for 90-day mortality in hospitalized patients adjusted for confounders (sex, age, type of VTE, obesity, CKD, CHF, COPD, and cancer) was 1.99 (95% CI 1.49-2.64; p=0.01). Conclusions: In this elderly, and predominantly female Argentine population, the 90-day mortality in patients hospitalized for VTE was higher than mortality in patients with outpatient management, without differences in recurrence or major bleeding.

Development and validation of COEWS (COVID-19 Early Warning Score) for hospitalized COVID-19 with laboratory features: A multicontinental retrospective study.

Background: The emergence of new SARS-CoV-2 variants with significant immune-evasiveness, the relaxation of measures for reducing the number of infections, the waning of immune protection (particularly in high-risk population groups), and the low uptake of new vaccine boosters, forecast new waves of hospitalizations and admission to intensive care units. There is an urgent need for easily implementable and clinically effective Early Warning Scores (EWSs) that can predict the risk of complications within the next 24-48 hr. Although EWSs have been used in the evaluation of COVID-19 patients, there are several clinical limitations to their use. Moreover, no models have been tested on geographically distinct populations or population groups with varying levels of immune protection. Methods: We developed and validated COVID-19 Early Warning Score (COEWS), an EWS that is automatically calculated solely from laboratory parameters that are widely available and affordable. We benchmarked COEWS against the widely used NEWS2. We also evaluated the predictive performance of vaccinated and unvaccinated patients. Results: The variables of the COEWS predictive model were selected based on their predictive coefficients and on the wide availability of these laboratory variables. The final model included complete blood count, blood glucose, and oxygen saturation features. To make COEWS more actionable in real clinical situations, we transformed the predictive coefficients of the COEWS model into individual scores for each selected feature. The global score serves as an easy-to-calculate measure indicating the risk of a patient developing the combined outcome of mechanical ventilation or death within the next 48 hr.The discrimination in the external validation cohort was 0.743 (95% confidence interval [CI]: 0.703-0.784) for the COEWS score performed with coefficients and 0.700 (95% CI: 0.654-0.745) for the COEWS performed with scores. The area under the receiver operating characteristic curve (AUROC) was similar in vaccinated and unvaccinated patients. Additionally, we observed that the AUROC of the NEWS2 was 0.677 (95% CI: 0.601-0.752) in vaccinated patients and 0.648 (95% CI: 0.608-0.689) in unvaccinated patients. Conclusions: The COEWS score predicts death or MV within the next 48 hr based on routine and widely available laboratory measurements. The extensive external validation, its high performance, its ease of use, and its positive benchmark in comparison with the widely used NEWS2 position COEWS as a new reference tool for assisting clinical decisions and improving patient care in the upcoming pandemic waves.

Prevalence of the use of antidepressants in patients with venous thromboembolism / Prevalencia del uso de antidepresivos en pacientes con enfermedad tromboembólica venosa.

OBJECTIVE: To estimate the prevalence of Antidepressant use in patients with a history of venous thromboembolism (VTE). Describe the patient's characteristics and which drugs are the most prescribed. METHODS: A cross-sectional study involving a consecutive sample of patients included in the Registro de Enfermedad Tromboembólica (RIET) from the Hospital Italiano de Buenos Aires in a period between 01/01/2014 to 01/09/2018. All patients presented symptomatic VTE and confirmed diagnosis. Drugs considered included in this study were: Selective Serotonin Reuptake Inhibitors (SSRI), Dopamine and Norepinephrine Reuptake Inhibitors (NDRI), Serotonin and Norepinephrine Reuptake Inhibitors (SNRI) and Tricyclic antidepressants (TCA). RESULTS: From a total of 2373 patients with VTE, 472 were active users of antidepressants, showing a prevalence of antidepressant use of 19.9% (CI 95%). The most frequently prescribed drugs by drug classification were: SSRI 83.9%, TCA 20.5%, ISRN 14.6%, and NDRI 2.5%. Patients presented a median age of 76 years, predominantly women (71.4%), with several comorbidities: 52.24% arterial hypertension, 37.29% overweight, and 34.75% history of smoking. Concerning relevant history, we observed: 29.03% active oncologic disease, 26.27% major surgery before the VTE, and 21.61% previous VTE. CONCLUSION: The prevalence of antidepressant use in patients with VTE is 19.9%, superior by far to that of the general population. Depression is a major cause of morbidity worldwide, and its prevalence is increasing over the years.

OBJETIVOS: Estimar la prevalencia de consumo de fármacos antidepresivos en pacientes que hayan sufrido un evento tromboembólico venoso (TEV), describir esta población y las drogas más utilizadas. MATERIAL Y MÉTODOS: Corte transversal que incluyó una muestra consecutiva de adultos incluidos en el Registro de Enfermedad Tromboembólica (RIET) del Hospital Italiano de Buenos Aires entre el 01/01/2014 y el 1/09/2018. Se consideraron los siguientes fármacos: Inhibidores Selectivos de la Recaptación de Serotonina (IRSS), Inhibidores de la Recaptación de Dopamina y Noradrenalina (IRDN), Inhibidores de la Recaptación de Serotonina y Noradrenalina (IRSN), y Antidepresivos Tricíclicos (ATC). RESULTADOS: De un total de 2373 pacientes, 472 se identificaron como usuarios activos de antidepresivos, arrojando una prevalencia de 19,9% (IC95% de 18,3-21,6). Según familia farmacológica, en orden de mayor a menor frecuencia, se indicaron: IRSS 83,9%, ATC 20,5%, IRS 14,6% e IRDN y IRDN 2,5%. Los pacientes bajo tratamiento con antidepresivos presentaron una mediana de edad de 76 años, mayoritariamente mujeres (71,4%), con alta carga de comorbilidad: 52,24% hipertensión arterial, 37,29% sobrepeso, 34,75% ex tabaquismo. Los antecedentes de mayor frecuencia resultaron enfermedad oncológica activa (29,03%), cirugía mayor en último mes (26,27%), y el 21,61% presentaba ETV previa. CONCLUSIONES: La prevalencia de uso de antidepresivos en pacientes con ETV resultó 19,9%, superior a la población general. La depresión es una causa principal de enfermedad y discapacidad en todo el mundo, cuya prevalencia aumentó durante los últimos años.
