Development of a diagnostic multivariable prediction model of a positive SARS-CoV-2 RT-PCR result in healthcare workers with suspected SARS-CoV-2 infection in hospital settings.

Background: Despite declining COVID-19 incidence, healthcare workers (HCWs) still face an elevated risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. We developed a diagnostic multivariate model to predict positive reverse transcription polymerase chain reaction (RT-PCR) results in HCWs with suspected SARS-CoV-2 infection.

Methods: We conducted a cross-sectional study on episodes involving suspected SARS-CoV-2 symptoms or close contact among HCWs in Bogotá, Colombia.

Impact of urinary catheter on resistance patterns and clinical outcomes on complicated urinary tract infection.

Introduction And Hypothesis: Complicated urinary tract infection (cUTI) is highly prevalent and costly for health systems. The impact of the indwelling urinary catheter on etiologic agents and clinical outcomes has been poorly studied in Latin America.

Methods: Cross-sectional study including patients with cUTI, with positive urine culture, treated at Hospital Universitario San Ignacio, Bogotá (Colombia) between 2017 and 2020.
