Bacteriemia en pacientes adultos dados de alta en el servicio de urgencias

Abstract

IntroductionBacteraemia is a marker of severity of infectious processes. However, sometimes in Emergency Department blood cultures are drawn from patients who are discharged without results being available. Material and methodsProspective study of bacteraemia was conducted on adult patients from Emergency Department of tertiary university hospital from March 2014 to February 2015. Epidemiological, clinical and microbiological data were collected from patients admitted and discharged. After the detection of bacteraemia, the microbiology department telephoned the physician responsible (patients admitted) or Primary Care physician (patients discharged). ResultsA total of 429 episodes of bacteraemia were included, of which 13.52% were discharged. These patients were younger (68.5 vs 73.59 years, P=.0001), had a lower Charlson index (1.603 vs 2.309, P=.0013) and lower severity (septic shock 0 vs 34; P<.0001) than admitted patients. After the call to Primary Care, oral antibiotics were started in 10.3%, a change in oral antibiotic in 6.9%, 12% were admitted to hospital, and the rest of them continued same treatment. The 30-day mortality rate was 0%. ConclusionsThere was a significant number of patients with bacteraemia were discharged from Emergency Department. To discharge a clinically stable patient with blood cultures taken in Emergency Department is safe, if there is a re-assessment of the patient if these cultures are positive.
