465,289 chemotherapy authorizations, 29,151 for radiotherapy, and 383,568 hospital admissions for children and adolescents in Brazil's Unified Health System were tracked between 2000 and 2007. The analysis, by Marília Fornaciari Grabois of Instituto Nacional do Câncer, maps origin-destination flows between health districts. It identifies 48 chemotherapy, 53 radiotherapy, and 112 hospital admission networks, revealing that most care occurred in districts of Brazil's 12 largest cities.
Use Cases
- Modeling healthcare network efficiency based on origin-destination flow data.
- Identifying gaps in regional cancer care coverage based on travel occurring outside dominant networks.
- Planning service distribution to meet population needs based on mapped treatment volumes and urban system structure.
Strengths
- Analysis covers a significant 8-year period from 2000 to 2007.
- Dataset includes three distinct treatment modalities: chemotherapy, radiotherapy, and hospital admissions.
- Geographic unit of analysis (health care district) allows for spatial network modeling.
Limitations
- Row count and specific column definitions are unknown, limiting suitability assessment.
- Data is from 2000-2007; its freshness for current planning is unverified.
- Description metadata is limited; actual data quality requires manual inspection after download.
