Antimicrobial Resistance of Acinetobacter Baumannii in an Indian ICU, 2019-2025

Deepthi Puttegowda's study analyzes 3,540 non-duplicate clinical isolates of Acinetobacter baumannii from endotracheal aspirates collected between 2019 and 2025 in a tertiary-care hospital in South India. The data includes prevalence, demographic associations, and antimicrobial susceptibility patterns for multidrug-resistant strains. Results show a 20.2% prevalence of MDR A. baumannii, with high resistance rates to carbapenems, ciprofloxacin, and other agents.

Use Cases

• Analyze prevalence trends of multidrug-resistant Acinetobacter baumannii based on ICU type and patient demographics.
• Model antimicrobial susceptibility patterns based on resistance rates for carbapenems, fluoroquinolones, and aminoglycosides.
• Evaluate the discriminatory performance of common antibiotics for guiding empirical therapy based on ROC curve analysis results.
• Assess demographic risk factors for infection based on patient age and sex distributions mentioned in the results.

Strengths

• Contains 3,540 non-duplicate clinical isolates, providing a substantial sample for analysis.
• Covers a 6-year time range from 2019 to 2025, allowing for temporal trend observation.
• Includes specific, quantified resistance rates for multiple antibiotics (e.g., meropenem 66.4%, ciprofloxacin 71.8%).
• Provides detailed demographic breakdowns, such as 74% of isolates from male patients.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the final dataset is unknown, which may limit suitability assessment.
• Data is from a single-center study in South India, which may limit generalizability to other geographic or healthcare settings.
