Introduction: the high incidence and prevalence of urinary tract infections in both hospital patients and outpatients determine that the exact knowledge of the major etiologic agents with antimicrobial susceptibility patterns gain immeasurable epidemiological and economic assistance values. Objective: to do Microbial map for hospital patients, and outpatients suffering from UTIs. Methods: a retrospective and cross study was conducted in 13,939 urine cultures from inpatient and outpatients received in the Microbiology Laboratory at Hermanos Ameijeiras hospital from September 2009 to August 2010. Results: 62 % of the samples were negative, 22 % positive, and 16 % were reported as the contaminated samples representing a cost of 86 100, 61 980, and 22 300 CUC, respectively, with an overall total of 170 380 CUC. The microorganism most frequently isolated was Escherichia coli in both groups (76.4 % and 54.0 % respectively), which were higher than 55 % to trimethoprim/sulfamethoxazole and ciprofloxacin. Ampicillin resistance was close to 90% for almost all microorganisms. Nitrofurantoin for Escherichia coli presented the lowest percentages of resistance. Antimicrobial resistance was higher in hospital patients. Conclusions: the monetary cost per patient for a second or third course of antibiotics, in an initial incorrect therapy, may imply spending approximately 100 times more than a correct initial therapy based on scientific evidence.

Palabras clave : antimicrobial susceptibility; monetary cost per patient.
