[Characteristics of acute pyelonephritis at a short-stay medical unit].
OBJECTIVE
To analyze the epidemiological characteristics of the population admitted to a short-stay medical unit (SSMU) during 2005 due to acute pyelonephritis. To describe and analyze microbiological aspects recorded in these infections and their clinical implication. MATERIAL AND METHOD. A retrospective study was carried out in a cohort of 208 patients admitted in the SSMU during 2005 because of acute pyelonephritis. Epidemiological, clinical and microbiological data were collected. The statistical analysis was done with the SPSS v. 14.0.


RESULTS
208 patients were included, 74% of whom were females. Average age was 43.6 (16-87). Mean length of stay was 4.7+/-1.2 days and 96.6% of patients were discharged successfully from SSMU. Urine culture was valid in 173 patients, 51.4% of which were positive. Escherichia coli was isolated in 93.2% of urine cultures. Blood cultures were valid in 178 cases and in 37 of which were positive. E. coli was isolated in 64.8% of these. In E. coli urine samples, resistance rate to ampicillin was 68.7%, to cotrimoxazole 22.9%, to ciprofloxacin 18.1%; to amoxicillin/clavulanic acid 16.9% and to fosfomycin 2.4. Seven patients were transferred to hospital home care, there being no deaths.


CONCLUSIONS
Acute pyelonephritis with admission criteria can be managed successfully in the SSMU with the applicable therapeutics guidelines with regard to the most common microbiological aspects registered and the low incidence of complications.
