Summary
During a period of 10 years, 293 of 4270 admissions to the general intensive care unit (ICU) at Medway Maritime Hospital had 356 bacteraemias due to one of 14 microorganisms. Incidence of bacteraemia was least on the third day after admission, significantly greater on the fifth day and stable thereafter. From the fifth day the acquisition rate was 18.9 (16.5–21.3)/1000 bed-days, lower in those with an initial Acute Physiological Assessment and Chronic Health Evaluation II score (APII) <18, or admitted from the emergency room. A total of 1395 patients with no positive cultures in the first four days stayed in ICU for ≥5 days, and 204 subsequently had one or more bacteraemias. Hospital mortality in these patients was 45.6% (38.8–52.4), greater than in those with similar APII but sterile cultures . Observed mortality was greater than predicted only in bacteraemic patients . ICU-acquired bacteraemia was associated with an approximate additional absolute mortality of 11% contributing 0.5% to the 29.9% hospital mortality of all ICU admissions, 1.6% to the 34.6% of those staying ≥5 days, and 5.6% to the 35.9% of those remaining >24 days.

Summary
Staphylococcus aureus (SA) is becoming increasingly resistant to antibiotics in hospitals and the community. Long-term outcomes following susceptible and resistant SA infection have not been studied. We performed a retrospective matched pair analysis of all patients with positive culture for meticillin-resistant SA (MRSA) or meticillin-susceptible SA (MSSA) from any site to assess the outcomes of infection. Data were collected for length of hospitalisation and in-hospital mortality, as well as longer-term outcomes including all-cause mortality, number of rehospitalisations and subsequent cultures for SA during the year following infection. Twelve months after their initial SA infection, 42% of patients were dead. There were no differences between the groups in short-term mortality, length of hospitalisation, number of subsequent hospitalisations and cultures for SA during the year following infection. Following discharge, however, MRSA infection was associated with higher mortality than MSSA at three months (32% vs 18% P = 0.02), six months (42% vs 22% P = 0.002) and 12 months (51% vs 32% P = 0.005). In conclusion, SA infection is associated with a high one-year all-cause mortality. Most deaths occur after discharge. The likelihood of dying during the year following infection is higher for patients with MRSA infection than for those with MSSA infection.
