Package 'microdatasus'

microdatasus: Download and prepare DataSUS microdata

Description

Provides a reproducible workflow for DataSUS microdata: fetch_datasus() discovers, downloads, and combines published DBC files; read_dbc() reads a local DBC file; and the ⁠process_*()⁠ functions convert system-specific fields into analysis-ready values and labels.

Details

Start with fetch_datasus() and then use the processor corresponding to the selected system, such as process_sim(), process_sinasc(), process_sih(), process_sia(), process_cnes(), or one of the ⁠process_sinan_*()⁠ functions. fetch_cadger() and fetch_sigtab() retrieve current auxiliary tables used by CNES and SIA processing.

For concepts, coverage, data flows, and caveats of each Brazilian health information system, see Saldanha (2026), Sistemas de Informação em Saúde no Brasil.

Download DataSUS microdata

Description

Downloads published DBC files from DataSUS, reads them with read_dbc(), and combines the records in deterministic period, state, and file-part order.

Usage

fetch_datasus(
  year_start,
  month_start = NULL,
  year_end,
  month_end = NULL,
  uf = "all",
  information_system,
  vars = NULL,
  stop_on_error = FALSE,
  timeout = 240,
  track_source = FALSE,
  quiet = FALSE
)

Arguments

year_start, year_end	Numeric scalars giving the first and last requested years, inclusive.
month_start, month_end	Numeric scalars giving the first and last requested months, inclusive. Months are required for SIH, SIA, and CNES systems and ignored, with a warning, for annual systems.
uf	A Brazilian state abbreviation, a character vector of abbreviations, or "all". "all" cannot be combined with individual states. A warning alert is displayed when this argument is ignored for systems published only as national files.
information_system	A single system identifier listed in Supported systems.
vars	NULL, or a character vector of column names to retain. Selection is applied to each file before the files are combined.
stop_on_error	Logical scalar. If TRUE, abort after any listing, download, or read failure. If FALSE, warn and return the files that could be read successfully.
timeout	A positive numeric scalar giving the connection and transfer timeout, in seconds, for each network attempt.
track_source	Logical scalar. If TRUE, append a source column with the original DBC file name. This column is retained even when vars is supplied. The function aborts if the downloaded data already contain a column named source.
quiet	Logical scalar. If FALSE (the default), display the transfer progress reported by curl::curl_download() and announce each file before downloading it. If TRUE, suppress status messages, per-file announcements, and progress meters. Warnings and errors are not suppressed.

Details

The function first lists the relevant DataSUS directories and downloads only files present in those listings. When more than one publication represents the same system, period, state, and file part, definitive/current data take precedence over preliminary data, and current data take precedence over historical copies.

Downloads are sequential. Unless quiet = TRUE, transfer progress is displayed by curl::curl_download(). Transient network failures are retried up to two times; missing, empty, invalid DBC, and incompatible-schema files are not retried. Partial files and other temporary files are removed before the function returns or aborts.

Years and state abbreviations refer to DataSUS processing periods and places of processing, which may differ from dates or places of occurrence and residence contained in the records.

Value

A tibble containing all successfully read records, or NULL if no requested file could be read. No diagnostic attributes are added.

Prepare CNES microdata

Description

Recodes supported CNES fields into descriptive values and normalizes escaped Unicode text. Establishment ("CNES-ST") and professional ("CNES-PF") records have different layouts and are processed accordingly.

Usage

process_cnes(
  data,
  information_system = c("CNES-ST", "CNES-PF"),
  nomes = FALSE,
  municipality_data = TRUE
)

Arguments

data	A data frame returned by fetch_datasus() or another data frame with a compatible CNES layout.
information_system	A single character string: "CNES-ST" for establishments or "CNES-PF" for professionals.
nomes	Logical scalar. For "CNES-ST" data, if TRUE, download the current CADGER table with fetch_cadger() and add establishment trade names. This requires network access. It has no effect for "CNES-PF".
municipality_data	Logical scalar. If TRUE, add municipality names and available territorial attributes for supported municipality-code columns.

Details

Columns not explicitly recoded are retained, but Unicode normalization is applied to every column and consequently the returned tibble contains character columns. Lookup joins can add establishment, occupation, and municipality information.

Value

A tibble with character columns. Supported codes are replaced with descriptions, and requested lookup fields are added where applicable.

municipality_data	Logical scalar. If TRUE, add municipality names and available territorial attributes for supported municipality-code columns.

Details

Columns not explicitly recoded are retained, but Unicode normalization is applied to every column and consequently the returned tibble contains character columns. Other SIA layouts downloadable with fetch_datasus() are not currently supported by this processing function.

Value

A tibble with character columns. Supported codes are replaced with descriptions, and requested lookup fields are added where applicable.

Read a DBC file

Description

Decompresses a DataSUS DBC file to a temporary DBF file and reads it into a tibble. Use this function for a DBC file already available locally; use fetch_datasus() to discover and download files from DataSUS.

Usage

read_dbc(file, as_character = TRUE)

Arguments

file	A single character string with the path to a readable, non-empty DBC file.
as_character	If TRUE (the default), converts every column to character. If FALSE, preserves the types inferred from the DBF metadata.

Details

Decompression is performed through the package's bundled DBC implementation. The intermediate DBF file is created in the R temporary directory and removed before the function returns or aborts. The implementation was adapted from the healthbR package.

Invalid input files, decompression failures, and DBF reading failures abort with errors in the microdatasus_dbc_error family.

Value

A tibble with one column per DBF field. By default, all columns are character vectors; with as_character = FALSE, DBF-inferred types are retained.
