Bacteremia in Cancer Patients with 28-Day Mortality and Resistance Factors, Peru 2020-2024

293 adult cancer patients with bacteremia were studied at a referral center in Lima between July 2020 and June 2024. Yosué Vera's research found a 28-day all-cause mortality rate of 32.1%, with severity of infection and comorbidities identified as primary drivers rather than antimicrobial resistance.

Use Cases

• Predict 28-day mortality risk in cancer patients with bacteremia based on factors like sepsis, septic shock, and Charlson Comorbidity Index.
• Analyze the prevalence and impact of antimicrobial resistance, such as ESBL-producing Enterobacteriaceae and carbapenem-resistant Gram-negative bacteria.
• Model associations between bacteremia characteristics (e.g., primary source, pathogen type like CoNS) and patient outcomes.
• Study demographic and clinical profiles of cancer patients with bloodstream infections, including tumor type and disease activity.

Strengths

• Includes 293 patient records with detailed clinical and demographic variables like age (mean 65.4 years), gender (53.9% female), and tumor type (84.3% solid tumors).
• Provides a clear 28-day mortality outcome (32.1%) and associated risk factors with statistical measures (e.g., Relative Risk from Poisson regression).
• Covers a defined four-year time range (July 2020 to June 2024) at a single referral center, allowing for temporal consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known (293), but the dataset is very small (5.5 KB), which may limit statistical power for some analyses.
• Data reflects a single-center study in Lima, Peru, which may limit generalizability to other geographic or healthcare settings.
