Item Factors Associated with Nutritional Risk Assessment in Critically Ill Patients Using the Malnutrition Universal Screening Tool (MUST)(MDPI, 2024) Díaz Chavarro, Blanca Cecilia; Molina Recio, Guillermo; Assis Reveiz, Jorge Karim; Romero Saldaña, ManuelBackground: Malnutrition is an underdiagnosed condition that negatively affects the clinical outcomes of patients, being associated with an increased risk of adverse events, increased hospital stay, and higher mortality. Therefore, nutritional assessment is a required and necessary process in patient care. The objective of this study was to identify the factors associated with nutritional risk by applying the Malnutrition Universal Screening Tool (MUST) scale in a population of critically ill patients. Methods: This was an observational, analytical, and retrospective study. Sociodemographic, clinical, hematological, and biochemical variables and their relationship with nutritional risk and mortality were analyzed. Results: Of 630 patients, the leading cause of admission was pathologies of the circulatory and respiratory system (50%); 28.4% were at high nutritional risk; and mortality was 11.6% and associated with nutritional risk, hemoglobin, and plasma urea nitrogen. Conclusions: The presence of gastrointestinal symptoms and the type of nutritional support received during hospitalization could increase the likelihood of presenting a medium/high nutritional risk, while polycythemia reduced this probability. An associative model was found to determine nutritional risk with an adequate specificity and diagnostic validity index.Item Frequency of antibiotic prescribing in adults hospitalized for SARS-CoV-2 in a high complexity institution in Santiago de Cali, Colombia(Asociacion Colombiana de Infectologia, 2023-04-23) Melo Burbano, Luis Álvaro; Galindes Casanova, Duván Arley; Benitez Escobar, Edith Norela; Assis Reveiz, Jorge Karim; Daza Arana, Jorge Enrique; Oñate Gutiérrez, José MillánObjective: To determine the frequency of antibiotic use and to know which clinical and socio-demographic variables were related to the probability of suffering infections associated with COVID-19.Methods: Adults hospitalized for COVID-19 who received one or more antibiotics during hospitalization were evaluated. We performed a descriptive analysis of variables in the general population' bivariate analysis in two groups (documented vs. presumed infection) and multivariate logistic regression of factors associated with mortality.Results: We determined that 60.4% of adults hospitalized for COVID-19, received antibiotics. Co-infection was documented in 6.2% and superinfection in 23.3%. Gram-negative germs were reported in 75.8% of cultures, fungi in 17.8% and gram-positive in 14.2%. Variables such as age, comorbidities, ICU, anemia, steroids, mechanical ventilation, hemofiltration were statistically significantly related to documented infection. High-flow cannula was associated as a protective factor. Overall mortality was 43.9%, 57.8% in the first group and 38.1% in the second (p=0.002).Item Impact of Central Line-Associated Bloodstream Infections on Mortality and Hospital Stay in Adult Patients at a Tertiary Care Institution in Cali, Colombia, 2015–2018(American Institute of Physics, 2024) Mosquera, Jorge Mario Angulo; Assis Reveiz, Jorge Karim; Barrera, Lena; Liscano, YamilBackground: Central line-associated bloodstream infections (CLABSIs) are a significant healthcare challenge globally, increasing mortality risk and complicating central vascular catheter use. In Colombia, few studies have assessed the impact of CLABSIs on hospital stay and mortality. Objective: To determine the association between CLABSIs and discharge outcomes and hospital stay duration in adult patients at a tertiary care institution in Cali, Colombia, from 1 January 2015 to 31 December 2018. Methods: A nested case–control study was conducted. The odds of mortality associated with CLABSIs were estimated using conditional logistic regression. Non-conditional logistic regression was used to determine the odds of mortality when CLABSIs were caused by resistant microorganisms. Hospital stay duration, catheter duration, and time from catheter insertion to discharge were compared between patients with and without CLABSIs. The most frequent etiological agents were identified. Results: Patients with CLABSIs had 3.89 times the odds of mortality (95% CI [1.33–11.31], p = 0.013) compared to those without CLABSIs. The odds of mortality for patients with resistant microorganism CLABSIs were 4.04 times (95% CI [1.17–13.96], p = 0.027) higher than those with sensitive microorganism CLABSIs. Hospital stay duration (median = 51 days vs. 17 days; p = 0.000), catheter duration (median = 19 days vs. 7 days; p < 0.001), and time from catheter insertion to discharge (median = 40 days vs. 9 days; p < 0.001) were significantly longer in CLABSI patients. Klebsiella pneumoniae was the most isolated pathogen (20.2%), followed by Staphylococcus aureus (14.9%). Implications: CLABSI patients have longer catheter and hospitalization durations and higher mortality risk. Resistant microorganism CLABSIs are associated with elevated mortality risk. Conclusions: This study corroborates the positive relation between CLABSI and the mortality risk, which is influenced by resistant bacteria, though causality is not established. CLABSI is also linked to longer hospital stays, underscoring the need for improving infection control strategies.Item Nutritional State, Immunological and Biochemical Parameters, and Mortality in the ICU: An Analytical Study(2023-07) Díaz Chavarro, Blanca Cecilia; Romero Saldaña, Manuel; Assis Reveiz, Jorge Karim; Molina Recio, GuillermoIntensive care unit (ICU) hospitalization involves critically ill patients with multiple diseases and possible complications, including malnutrition, which increases hospital stay and mortality. Therefore, identifying the patient’s prior nutritional state, following up during hospitalization, and implementing early intervention positively affect patient’s vital situations at discharge. The objective of this study is to determine the nutritional state of patients admitted to an ICU in Cali (Colombia) in 2019 and its association with immunological and biochemical parameters and mortality observed during hospitalization. This was an observational, analytical, and retrospective study of patients admitted to an ICU in a clinic in Cali (Colombia) from 1 January to 31 March 2019. The association between their nutritional state and outcome variables such as hospital stay, immunological and biochemical function, and mortality was analyzed. Logistic regression was used to predict patients’ vital status at hospital discharge. In terms of the nutritional level, low weight was observed in 17.5% patients, and overweight/obesity was observed in 53.5% of the population. Nutritional state was associated with leukocytosis. The patients with lymphocytosis had longer hospital stays than those with normal lymphocyte ranges. Age, blood leukocytes, and creatinine and potassium levels increased the risk of mortality. Lymphocyte values have been used as predictors of severity and hospitalization time. The scientific literature has also evidenced a higher leukocyte count in people with obesity, and such leukocytosis is associated with the risk of mortality. The results of blood and laboratory tests determining kidney function and blood electrolytes allow for the prediction of mortality risk in critically ill patients.Item Revascularización miocárdica: Tópicos selectos para profesionales de la salud(Editorial Universidad Santiago de Cali, 2025-03-22) Daza Arana, Jorge Enrique; Lozada Ramos, Heiler; Bernal Sánchez, José Julián; Vivas López, Luis Fernando; Sánchez Soto, Tulio Hernán; Assis Reveiz, Jorge Karim; Romero Serna, Andrés David; Lanas Zanetti, Fernando; Guevara García, Juan Guillermo; Clavijo Prado, Carlos Andrés; Medina Gallo, Luis Felipe; Edward David Buriticá Marín;
