Market Access Terminology: What is a DRG?

A Diagnosis-Related Group (DRG) is a classification system used in the healthcare sector to group patients according to specific clinical and statistical criteria. 

It facilitates delivery of medical care, resource management, and evaluation of treatment effectiveness. 

Key purposes of DRG-based approach: 

1. Treatment standardization: DRGs enable clinicians and medical facilities to apply uniform approaches to diagnosing and treating specific conditions. 

2. Efficient resource allocation: Grouping patients by DRGs assists in more efficient use of medical resources such as hospital beds, medications, and equipment. 

3. Data analysis: The system allows for the collection and analysis of morbidity data, fostering improvements in healthcare quality and identification of system weaknesses.

How is the system applied? 

In the DRG-based system, disorders are classified by multiple criteria, such as: 

• Diagnosis (e.g., chronic disease, acute infection) 

• Patient age 

• Presence of comorbidities 

• Treatment modality 

For example, the DRG classification for cardiovascular diseases includes patients with diagnoses like ischemic heart disease, hypertension, and heart failure. These diagnoses are further divided into subgroups based on severity of patient’s condition and treatment method used. 

International Experience 

DRGs are used worldwide in various countries to streamline healthcare services. Examples include: 

• USA: DRG-based system in the United States is employed to categorize patients by diagnosis and link treatment costs to a respective group, helping payers and governmental agencies control health expenditure.   

• Australia: The Australian Refined Diagnosis Related Groups (AR-DRG) system adapts the DRG model to Australia’s health system specifics and aids in resource allocation planning.

Local Experience

The DRG model was introduced in Russia in the 1990s and has undergone several changes since then. However, its core functions remain unchanged: 

1. Healthcare funding: DRGs are used to calculate treatment rates under OMS system. Each disease group has a designated rate assigned to it, which helps control medical facilities’ spending. 

2. Disease classification: Russia has developed its own DRG classification that reflects the specifics of the national healthcare system. The ICD (International Classification of Diseases) coding system is integrated with the national DRG system. 

3. Treatment quality monitoring: The use of the model enables the analysis of treatment outcomes and the detection of weaknesses in the healthcare system. This contributes to raising the quality of medical services and promoting better public health. 

Diagnosis-Related Groups (DRGs) play a crucial role in healthcare management in Russia and worldwide. They help standardize treatment protocols, streamline resources, and analyze morbidity data.
