Contrasting methods to operationalize antibiotic exposure in clinical research: a real-world application on health care–associated Clostridioides difficile infection
To summarize common methods of antibiotic operationalization in clinical research and demonstrate exposure variable selection methods, ensuring clarity for diverse audiences.
Key Findings:
Eight key variables were identified through factor analysis, which are crucial for understanding antibiotic exposure.
Logistic regression highlighted the importance of overall antibiotic exposure and duration, suggesting areas for clinical focus.
LASSO regression emphasized the complexity of antibiotic exposure with multiple relevant variables, indicating the need for nuanced approaches.
Interpretation:
Investigators should consider multiple characteristics of antibiotic exposure tailored to their research questions and theoretical frameworks, enhancing the relevance of their findings.
Limitations:
Study limited to a single hospital's electronic health records, which may introduce biases.
Findings may not be generalizable to other settings or populations, necessitating caution in application.
Conclusion:
A comprehensive understanding of antibiotic exposure is essential for studying its effects on health care-associated infections, guiding future research directions.
