• Purpose: The primary purpose of the UHDDS is to collect data that can be used to analyze healthcare utilization, costs, and outcomes.
• Impact on DRGs: The UHDDS data is used to calculate Diagnosis-Related Groups (DRGs), a classification system used to group patients with similar clinical characteristics. DRGs are used to determine hospital reimbursement rates.

UACDS: A Closer Look

• Description: The UACDS is a standardized data set used to collect patient-level data on outpatient visits.
• Usage: It is used by ambulatory care providers, such as physician offices and outpatient clinics, to report data to state and federal agencies.
• Purpose: The primary purpose of the UACDS is to collect data that can be used to analyze healthcare utilization, costs, and outcomes in outpatient settings.

Comparison of UHDDS and UACDS
