OMOP Delivery Report Generator

Generates HTML reports from OMOP CDM delivery metrics and data quality results. Part of the Connect for Cancer Prevention EHR data/OMOP pipeline.

Pipeline Position

This package operates downstream in the processing pipeline:

1. ccc-omop-file-processor - Processes OMOP files, performs vocabulary harmonization, outputs delivery_report.csv
2. DataQualityDashboard - Runs quality checks (via ccc-omop-analyzer), outputs dqd_results.csv
3. omopDeliveryReport (this package) - Combines both CSVs into HTML report

Installation

remotes::install_github("Analyticsphere/omopDeliveryReport")

Sample input files and a rendered report are available in inst/ref/.

Usage

library(omopDeliveryReport)

# Local file system
generate_omop_report(
  delivery_report_path = "inst/ref/delivery_report.csv",  # Sample data in package
  dqd_results_path = "inst/ref/dqd_results.csv",          # Sample data in package
  output_path = "~/Desktop/example_omop_report.html"
)

# Files in GCS
generate_omop_report(
  delivery_report_path = "gs://bucket/delivery_report.csv",
  dqd_results_path = "gs://bucket/dqd_results.csv",
  output_path = "gs://bucket/report.html"
)

Input Files

delivery_report.csv

Generated by ccc-omop-file-processor via /generate_delivery_report endpoint.

Contents:

• Table row counts (initial, invalid, harmonized, final)
• Vocabulary harmonization statistics
• Domain migration flows
• Type concept breakdowns
• Time series data
• Reference integrity results

dqd_results.csv

Standard output from OHDSI DataQualityDashboard. Contains check results, failure counts, and check metadata organized by table, field, and check category.

Architecture

Processing Pipeline:

Load CSV → Parse Metrics → Calculate Scores → Build HTML → Write Output

The package combines two CSV files (delivery metrics and DQD results) into a single interactive HTML report. Each R module handles one stage of the processing pipeline. Parsers extract metrics using regex patterns, calculators compute scores, and builders assemble HTML from templates using {{variable}} substitution. Works with both local files and Google Cloud Storage.
