Microdatasus: Brazilian Health System Microdata via R Package

Microdatasus is an R package providing direct access to microdata from Brazil's Unified National Health System (SUS). The algorithm downloads and preprocesses data from various health information systems, including automatic labeling of categorical fields. This enables a continuous workflow for analyzing health data within the R statistical environment.

Use Cases

• Analyze public health trends based on data from multiple Brazilian health information systems
• Study categorical health variables based on the automatic labeling feature described
• Conduct epidemiological research based on microdata from the Brazilian Unified National Health System (SUS)

Strengths

• Provides direct access to microdata from Brazil's national health system, reducing manual download workload
• Includes preprocessing functions for automatic coding of categorical fields, streamlining analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks
