PURPOSE: We report the incidence of MDR Acinetobacter infection in Long Term Acute Care Hospitals (LTACHs) in Southern California from January 2008 through December 2008 in long term care facilities with high number of patient with tracheotomies and ventilators.
METHODS: We monitor infection rates base on hospital days in LTACHs where there are high number of patients on chronic ventilators. Acinetobacter were isolated from the patient’s sputum in patients with clinical evidence of infection. Susceptibilities on these bacteria were also performed.
RESULTS: We isolated 152 cases of Acinetobacter infection out of 331 nosocomial infection, at 46% of all nosocomial infections. These organisms were resistant to at least three antibiotics.
CONCLUSION: The rate of MDR Acinetobacter is much higher than previously reported. The reason is that these LTACHs take care of patients on long term ventilators support. These patients are at the highest risk . The majority of these patients were transferred to these hospitals with MDR Acinetobacter from other facilities.
CLINICAL IMPLICATIONS: The incidence of Acinetobacter infection has been increasing in the US and around the world. The reported incidence ranges from 6 percent to as high as 35 percent of hospital acquired infection. The most common manifestations of Acinetobacter outbreak infection have been nosocomial pneumonia (primarily ventilator-associated) followed by bacteremia. Recently there are reports of numerous outbreaks of Acinebacter infections in the hospitals throughout the US. We are also seeing significant increase in MDR organisms recently.
