Background-Acinetobacter baumannii (Ab) is emerging as a multidrug-resistant (MDR) nosocomial pathogen of considerable clinical importance. Data on the efficacy of infection control measures in endemic situations are lacking. Here, we investigated the impact of a long-term multifaceted "bundle" approach in controlling endemic MDR Ab in a 950-bed tertiary care center.

The effect of ascorbic acid on urine pH was studied in spinal cord injury patients. Their urine was not colonized by urease positive microorganisms. The study was designed to compare the baseline urine pH value and the urine pH value after the administration of placebo or ascorbic acid 500 mg/6 h. The diet and medical treatment were not controlled. A significant decrease in urine pH value was not obtained. There was no clinical benefit from the use of ascorbic acid.

Our data indicate that long-term control of endemic MRSA is feasible in tertiary care centers. The use of targeted active surveillance for MRSA in patients and healthcare workers in specific wards (identified by means of analysis of clinical epidemiology data) and the use of decolonization were key to the success of the program.
