RESUMO
Background: Non-critical care Hospital-Acquired Acute Kidney Injury (Non-ICU HA-AKI) is a preventable common complication. Aim: To analyze its risk factors and outcomes in a general hospital ward. Material and Methods: A retrospective paired case-control 1:2 study was carried out from April to December 2014. Non-ICU HA-AKI was defined as those patients who experienced a 1.5-fold, or 0.3 mg/dl rise in serum creatinine after 24 hours of hospitalization. Controls were randomly selected, paired by date of hospital admission and specialty causing the admission. We analyzed short-term outcomes and risk factors. Results: We included 101cases aged 65 ± 16 years (55% women). Mean length of stay at the time of diagnosis of AKI was 7.9 ± 8.9 days. Hospital length of stay was longer in patients with AKI (p < 0.01), The risk for intensive care unit (ICU) admission and mortality were also higher (odds ratio [OR], 2.43 [95% confidence intervals (CI), 1.24 to 4.75)p < 0.01 and OR, 26.2 [95% CI, 8.8 to 104, P < 0.01). In a multivariate analysis, sepsis (OR, 3.64 [95% CI, 1.30 to 10.16] p = 0.013), dehydration (OR, 14.4 [95% CI, 4.49 to 46.19), baseline glomerular filtration (OR, 0.96 [95% CI, 0.94-0.98), contrast medium exposure (OR, 4.33 [95% CI, 1.60 to 11.66), recent exposure to Nonsteroidal Anti-inflammatory Drugs (OR 3.23 [95% CI, 1.22 to 8.52 (p = 0.02)] and Charlson comorbidity index (OR, 1.23 [95% CI, 1.05 to 1.43 (p < 0.01) were independent risk factors for Non-ICU HA-AKI. Conclusions: Non-ICU HA-AKI is associated with a longer hospital stay and higher risk of ICU admission and mortality. Most risk factors are potentially preventable.

Abstract Introduction: Catheter-associated infection is an entity with multiple complications, a condition that alters the quality of life of all patients on hemodialysis. The aim was to estimate the prevalence of infection associated with intravascular hemodialysis devices at the San Rafael Clinical University Hospital over a period of two years, as well as to evaluate the associated infectious complications, readmissions and death in the study population. Methodology: Cross-sectional study of association in which the totality of hemodialysis patients attended in the institution during 2015 and 2016 was included. The analysis is presented in descriptive terms and associations of demographic variables and other outcomes with infection. Results: The prevalence of catheter-associated infection was 5.62%. A total of 320 patients were included, 18 with catheter-associated infection. The most common germ was methicillin susceptible Staphylococcus aureus with 61.1% of cases. There is a statistically significant association with septic thrombosis and the need for admission to the ICU (p = 0.0000).
Resumen Introducción: la infección asociada a catéter es una condición con múltiples complicaciones y altera la calidad de vida de todo paciente en hemodiálisis. En este estudio, se pretendió estimar la prevalencia de infección asociada a dispositivos intravasculares de hemodiálisis en el Hospital Universitario Clínica San Rafael, en un periodo de dos años, y evaluar las complicaciones infecciosas asociadas, reingresos y muerte en la población en estudio. Metodología: estudio transversal de asociación en el que se incluyó la totalidad de pacientes en hemodiálisis atendidos en la institución durante los años 2015 y 2016. El análisis se presenta en términos descriptivos y asociaciones de variables demográficas y otros desenlaces con infección. Resultados: la prevalencia de infección asociada a catéter fue de 5,62 %. Se incluyeron 320 pacientes en total, 18 con infección asociada a catéter. El germen más común fue Estafilococo aureus metilcilino sensible, 61,1 % de los casos. Existe una asociación estadísticamente significativa entre la trombosis séptica y la necesidad de ingreso a UCI (p 0,0000).
