INTERACT4 Trial Process Evaluation: Prehospital Blood Pressure Lowering in Stroke

A 2026 process evaluation of the INTERACT4 clinical trial, which investigated ambulance-delivered blood pressure lowering for hyperacute stroke patients in China. The dataset includes quantitative data on protocol fidelity and dose achievement, and qualitative interview data from 34 ambulance and hospital staff across 8 sites.

Use Cases

• Analyzing protocol fidelity and adherence rates based on quantitative case report form data mentioned in the description.
• Modeling factors influencing intervention success based on qualitative themes of system design and staff proficiency.
• Comparing centralized versus hospital-based ambulance system performance on clinical trial metrics.
• Training natural language processing models on thematic analysis of healthcare staff interviews.

Strengths

• Includes mixed-methods data combining quantitative metrics (e.g., 31.7% BP target achievement) and qualitative interview themes.
• Based on a defined trial framework (INTERACT4) with a clear process evaluation methodology.
• Interview data covers 34 participants (19 ambulance staff, 15 doctors) providing multiple perspectives.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small (147.2 KB), indicating limited scope, likely a document summarizing findings.
• Geographic coverage is limited to multiple sites in China, which may affect generalizability.
