BACKGROUND: Identification of factors that confer an increased risk of mortality in hospital acquired sepsis (HAS) is necessary to help prevent, and improve the outcome of, this condition.
AIM: To evaluate the clinical characteristics and factors associated with mortality in patients with HAS.
METHODS: Retrospective study of patients with HAS in a major Spanish Hospital from 2011 to 2015. Data from adults receiving any of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes associated with sepsis were collected. Those fulfilling the SEPSIS-2 definition with no evidence of infection during the first 48 hours following hospitalization were included (n=196). A multivariate analysis was employed to identify the risk factors of mortality.
FINDINGS: HAS patients were found to have many of the risk factors associated with cardiovascular disease (male sex, ageing, antecedent of cardiac disease, arterial hypertension, dyslipemia, smoking habit) and cancer. Vascular disease or chronic kidney disease were associated with 28 day mortality. Time from hospital admission to sepsis diagnosis, and the presence of organ failure were risk factors for 28-day and hospital mortality. Experiencing more than one episode of sepsis increased the risk of hospital mortality. "Sepsis Code" for the early identification of sepsis was protective against hospital mortality.
CONCLUSIONS: We have identified a number of major factors associated to mortality in patients suffering from HAS. Implementation of surveillance programmes for the early identification and treatment of sepsis translate into a clear benefit.
