First-Ever Stroke Risk After Hospital Encounters in Tasmania, 2007-2020

A 2007-2020 case-crossover study in Tasmania, Australia, investigating the association between hospital encounters and first-ever stroke risk within 90 days. The dataset includes 4,907 first-ever stroke patients, with 25% having a prior hospital encounter. It was authored by figshare admin karger and published under a CC-BY-4.0 license.

Use Cases

• Modeling stroke risk based on prior emergency department presentations and hospital admissions.
• Analyzing temporal patterns of stroke risk based on the 90-day and 7-day lookback periods.
• Identifying common diagnostic groups preceding stroke based on ICD-10-AM codes.
• Validating case-crossover study designs for acute event triggers.

Strengths

• Includes 4,907 first-ever stroke patient records.
• Provides specific odds ratios (e.g., OR 2.6, 95% CI 2.3-2.9) for risk associations.
• Covers a 13-year time range (2007-2020) from a defined geographic region (Tasmania, Australia).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Tasmanian population studied.
