Diagnosis-related groups (DRGs) group patients with similar needs based on their diagnoses, treatments, age, and expected discharge date. They are used to balance hospital workloads, determine reimbursements, and track patient outcomes. DRGs are classified into systems, with Medicare in the US having over 500 groups. Hospitals use DRGs to monitor patients and allocate resources. Insurance providers use DRGs to determine compensation and eliminate falsified records. Patients may shift between DRGs due to changes in their conditions.
A diagnosis-related group (DRG) is a grouping of patients who are expected to have similar needs, based on their diagnoses, treatments to date, and profiles in terms of age and expected discharge date. There are several systems used to classify diagnosis-related groups in hospital and clinical settings and are used for tasks such as balancing a hospital’s workload and determining the type of reimbursements hospitals are entitled to from government insurers, as well as private insurance companies. They can also be used to track patient outcomes and hospital cases.
A common classification system is the one used by Medicare in the United States, where there are more than 500 groups related to the diagnosis. Each group is based on why a patient is in the hospital and the type of procedures performed, with additional considerations such as age and complications. For example, “craniotomy for a patient older than 17” is a diagnosis-related group. People in this group are expected to use similar levels of hospital resources.
For hospitals, it’s important to balance workloads to ensure they have the staff, equipment and facilities they need to deliver the appropriate case. Using a diagnosis-related group system, hospitals can monitor their patients and see what kind of resources they have available. While every patient is different, people with similar underlying conditions and histories of procedures tend to use similar levels of resources, ranging from staff to imaging equipment.
Some insurance providers use a pay-for-performance system and track progress across facilities using diagnosis-related group systems to determine how much compensation a facility should receive. One benefit of standardized systems like this is the elimination of falsified or inflated records; If everyone within a group is expected to consume the same amount of resources, a base payment can be provided for each member of the group to cover associated expenses. Looking at performance within these groups can also be helpful in seeing how well a facility is meeting goals of care.
These grouping systems are very broad and recognize the sheer number of reasons people seek treatment and the potential for complications and comorbidities. Patients may shift between diagnosis-related groups as a result of changes in their conditions or cases, as seen when a patient develops serious complications that require more medical interventions. A patient’s diagnosis-related grouping is a matter for internal records, and patients are usually not told which diagnosis-related group they are in.
