[Estimation of incidence and analysis of sepsis in an area of Valencia (Spain)].
OBJECTIVE
To study the incidence of sepsis in an area of Valencia, as well as its characteristics, and to evaluate short-term outcomes.


METHODS
An active surveillance program was carried out to determine the incidence and characteristics of sepsis. All patients attending the Hospital de La Ribera from January 1999 to December 2004 were included. Incidence rates were calculated and logistic regression analysis was performed.


RESULTS
The incidence rate was 60.9 per 100,000 person-years. The incidence was highest among children younger than 1 year (1,138 per 100,000 person-years). A total of 14.4 % of cases were nosocomial infections. The most common microorganisms found were Escherichia coli, Streptococcus pneumoniae and Neisseria meningitidis. Microbiologically undocumented sepsis accounted for 32 % of the cases. The case-fatality rate was 1.3 %. Seventeen patients (11.1 %) were transferred to an intensive care unit (ICU). The risk of being transferred to an ICU was 14 times higher in patients with meningitis than in those with other sources of infection, independently of age and microbiological characteristics (OR 13.9, 95 % CI 2.6-75.3, P = 0.002).


CONCLUSIONS
The incidence rate of sepsis is high in the pediatric age group. Clinical sepsis represented an important percentage of pediatric sepsis in our center. The main factor associated with patient transfer to the ICU was the central nervous system as the source of sepsis.
