Epidemiology of nosocomial infections : 10-month experience in one hospital.
Infectious Diseases Forum, Roussel'93. Symposium. Acapulco (MEX), 1993/09/02.
We analyzed data on nosocomial infections obtained from the worldwide and Mexican medical literature and from the monitoring system at Regional Specialties Hospital No. 25 in Nuevo Le6n, Mexico.
We found a considerably higher incidence of hospital-acquired infections among patients in intensive care units.
The urinary and respiratory tracts were the predominant sites of nosocomial infection.
The principal causative organisms were the gram-negative bacilli, particularly Enterobacteriaceae, and some nonfermenting microorganisms, such as Pseudomonas species.
An increase also was noted in the isolation of coagulase-negative staphylococcus, particularly related to infections from foreign objects such as catheters and prostheses.
Analysis of the antimicrobial resistance patterns of 1045 bacterial strains, particularly those from the Enterobacteriaceae family, isolated at our hospital from November 1991 to August 1992 revealed that resistance to cefotaxime and amikacin is not a significant problem, even though these drugs have been used in the hospital for more than 10 years.
The incidence of nosocomial infections can be reduced through control measures such as epidemiologic monitoring systems, adherence to isolation procedures, the rational use of antimicrobial agents, and the use of susceptibility tests to determine bacterial resistance patterns in the hospital environment.
