Rationale: Acinetobacter baumannii (AB) has caused prominence as one of the greatest threats to medicine due to its alarming ability to accumulate diverse mechanisms of multidrug-resistance. Its recent emergence in incidence in causing nosocomial infections worldwide has made it a global concern.
Objective: To describe the clinical and microbiological profile of patients with clinically significant Acinetobacter baumannii infection admitted at Manila Doctors Hospital
Methods:Adult patients admitted from January 2015 to December 2015 at Manila Doctors Hospital positive for AB from different specimens were initially identified; charts of the respective subjects were retrieved for data collection.
Results: 87% of patients had clinical infection; 64% of the patients with infection were nosocomial in nature and 14 (22.9%) patients had MDR AB infection. Most common area of admission was at the private room (70.5%). Common isolated site of infection was respiratory in nature. Highest resistance rate for MDR group was observed with piperacillin at 91.7% (n=12) followed by tetracycline at 90.0% (n=11). Most of the patients with AB infection were resolved at 92% and a total of 3 deaths (4.9%) were attributed to AB infection.
Conclusion:Among adult patients admitted at the Manila Doctors Hospital with AB solates, majority were isolated from regular room admissions (70.5%) and were nosocomial respiratory infections.
Vigilant routine surveillance and good antimicrobial stewardship still remains key to prevent the spread and rise of multi-drug resistant isolates of this pathogen.
