Get cross-table domain coverage

Provides a high-level overview of data coverage across all OMOP CDM domain tables. For each clinical domain (conditions, drugs, procedures, measurements, etc.), returns row counts, person counts, and date ranges. This is useful for quickly assessing which data domains are populated and to what extent, without needing to query each table individually.

Usage

ds.omop.domain.coverage(
  scope = c("per_site", "pooled"),
  pooling_policy = "strict",
  symbol = "omop",
  conns = NULL,
  execute = TRUE
)

Arguments

scope

Character; "per_site" (default) or "pooled".

pooling_policy

Character; "strict" (default) or "pooled_only_ok".

symbol

Character; the session symbol (default: "omop").

conns

DSI connection object(s) or NULL to use the session default.

execute

Logical; if FALSE, return a dry-run result containing only the generated call code (default: TRUE).

Value

A dsomop_result object with $per_site (named list of data frames with columns table_name, row_count, person_count), $pooled (combined coverage when pooled), and $meta.

Examples

if (FALSE) { # \dontrun{
coverage <- ds.omop.domain.coverage(scope = "pooled")
coverage$pooled
} # }
