The Book of OHDSI
The Book of OHDSI is a comprehensive guide that explains how to use standardized data and open-source tools to study real-world health data. It helps researchers understand how to organize health data in a common format, check data quality, and perform studies on patient groups, treatment effects, and individual patient outcomes.
At a glance
Use when
Conducting real-world evidence studies, standardizing multi-center health data, performing distributed analytics, developing patient-level prediction models
Avoid when
When only small, isolated datasets are available with no plans for collaboration; when proprietary or closed research frameworks are required
Inputs
Observational healthcare data, clinical databases, research questions related to patient outcomes, treatments, and population health
Outputs
Standardized data models, validated evidence from observational studies, patient-level predictions, population-level estimates, data quality assessments
How it works
This book documents the OHDSI framework, including the OMOP Common Data Model and standard vocabularies for harmonizing observational healthcare data. It covers methods for data characterization, population-level estimation, and patient-level prediction, supported by open-source tools. The book also details processes for ensuring data quality, clinical validity, software validity, and method validity within a distributed research network.

- Assumptions
- Health data can be mapped to a common data model; observational data quality can be assessed systematically; distributed analysis improves generalizability and privacy
- Strengths
- Promotes reproducibility and scalability of real-world evidence; supports collaborative, open science; enables cross-database studies without centralizing sensitive data
- Limitations
- Requires significant effort to map local data to the OMOP CDM; expertise needed in data standardization and tool use; limited to observational data analysis
