Streptococcus Pneumoniae Serotype Distribution in Chile, 2016-2023

A retrospective study of 2016-2023 invasive pneumococcal disease cases from two public hospitals in Chile, authored by Angélica R. Bravo. Non-vaccine serotypes predominated, with pediatric vaccination coverage at 75.5% and adult mortality reaching 20.4%. The dataset likely contains demographic, clinical, vaccination, and serotype data for confirmed IPD patients.

Use Cases

• Analyze serotype replacement trends based on the prevalence of non-vaccine serotypes like 19A, 24F, and 6C.
• Compare pediatric and adult disease outcomes based on vaccination coverage and mortality data.
• Evaluate vaccine policy effectiveness based on the temporal shift in serotype distribution.
• Model disease burden based on demographic and clinical variables collected from hospital records.

Strengths

• Covers an 8-year time range (2016-2023) for longitudinal analysis.
• Includes specific mortality (20.4%) and vaccination coverage (75.5% pediatric, 6.3% adult) figures.
• Focuses on a defined geographic region (Chile) with data from two public hospitals.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the two-hospital sampling frame.
