ABSTRACT
Introduction: gastrointestinal involvement in COVID-19 occurs in approximately 20% of patients and may include nausea, vomiting, abdominal pain, diarrhea or abnormal liver function tests. In our country, the characteristics of gastrointestinal involvement in COVID-19 patients have not been studied. Objectives: to determine the prevalence of gastrointestinal and liver involvement in patients with COVID-19 treated at two hospitals in Bogotá, Colombia. To determine the association between COVID-19 gastrointestinal involvement and length of hospital stay, severity and mortality. Design and methodology: a cross-sectional study carried out at two hospitals in a hospital subnetwork in Bogotá, Colombia from February 2020 to March 2021. Results: a total of 1,176 patients with a positive reverse transcription polymerase chain reaction (RT-PCR) were included. Gastrointestinal manifestations occurred in 50% (95%CI 47-52%), with the most frequent being diarrhea in 18.4%, odynophagia in 17.6%, anorexia in 14.7% and abdominal pain in 8.8%. An association was found between diarrhea during hospitalization and prolonged hospitalization (OR 1.93 95%CI 1.19-3.13), and between gastrointestinal bleeding on admission and death (OR 3.13, 95%CI 1.1-9.1), among others. Abnormal liver function tests occurred in 46% (95%CI 43-49%) and were more frequent in patients with severe disease and those who died. Conclusions: the prevalence of gastrointestinal manifestations in patients with COVID-19 was 50%. Diarrhea was associated with a longer hospital stay, and gastrointestinal bleeding was associated with respiratory failure and death. Forty-six percent of patients had abnormal liver function tests, with elevated transaminases being the most frequent. Elevated aspartate transaminase (AST) on admission was associated with greater mortality. (Acta Med Colomb 2022; 48. DOI:https://doi.org/10.36104/amc.2023.2729).
ABSTRACT
Introducción El dolor precordial representa el 5% al 10% de las consultas anuales en los departamentos de emergencias; su diagnóstico suele ser dificultoso y a ello se le suma el problema que implican la externación de pacientes con patología coronaria aguda o las internaciones innecesarias. Esto ha llevado al desarrollo de diferentes sistemáticas para la evaluación de estos pacientes. Objetivo Validar en términos de seguridad y tiempos de estadía hospitalaria un nuevo algoritmo incorporado en nuestro centro que incluye la medición de troponina T de alta sensibilidad en pacientes con sospecha de síndrome coronario agudo. Material y métodos Se incluyeron 528 pacientes que consultaron en el servicio de emergencias con sospecha de síndrome coronario agudo y se les realizó el protocolo de unidad de dolor. Se analizaron variables clínicas, de laboratorio y el resultado de las pruebas funcionales efectuadas. En todos los pacientes se efectuó seguimiento a los 30 días. Resultados El 90,7% de los pacientes fueron externados luego de la observación y al seguimiento el 1,25% había presentado un evento cardíaco, representado por angioplastia coronaria e internación por síndrome coronario agudo; la especificidad del algoritmo global para el diagnóstico de síndrome coronario agudo fue del 97% y el valor predictivo negativo fue del 99%. El tiempo de estadía en el servicio de emergencias del total de los pacientes fue de 4,5 ± 2,5 horas. Conclusión El nuevo algoritmo incorporado en nuestro centro con determinación de troponina T de alta sensibilidad en pacientes con sospecha de síndrome coronario agudo demostró que es seguro al evitar la externación de pacientes que cursaban un síndrome coronario agudo y, a la vez, requiere una corta estadía hospitalaria en el servicio de emergencias.
Introduction Chest pain represents 5 to 10% of annual visits to emergency departments. Its diagnosis is sometimes difficult, with the added problem of inappropriate discharge of patients with acute coronary syndrome or unnecessary hospitalizations. This has led to the development of different algorithms for the evaluation of these patients. Objective The aim of this study was to validate, in terms of safety and length of hospital stay, a novel algorithm incorporated in our center, which includes measurement of high-sensitivity troponin T in patients with suspected acute coronary syndrome. Methods The study included 528 consecutive patients attending the emergency department with suspected acute coronary syndrome and evaluated according to the chest pain unit protocol. Clinical and laboratory variables and functional tests were analyzed. Follow-up at 30 days was performed in all the patients. Results After observation, 90.7% of the patients were discharged and 1.25% presented a cardiovascular event during follow-up, represented by percutaneous coronary intervention and hospitalization due to acute coronary syndrome. The specificity of the global algorithm for the diagnosis of acute coronary syndrome was 97% with a negative predictive value of 99%. Emergency department length of stay was 4.5 ± 2.5 hours for all the patients. Conclusion The novel algorithm incorporated in our center with measurement of high-sensitivity troponin T in patients with suspected acute coronary syndrome has proved to be safe, as it prevents the discharge of patients with acute coronary syndrome and at the same time reduces emergency department length of stay.
