A method to risk-adjust rehabilitation outcomes using functional related groups

Area of Science:

• Health Services Research
• Rehabilitation Medicine
• Health Outcomes Research

Background:

• Healthcare costs and complexity necessitate demonstrating value through outcomes data.
• Existing rehabilitation outcome measures often lack adequate adjustment for patient severity and health status.
• Accurate risk adjustment is crucial for fair evaluation of rehabilitation provider performance.

Purpose of the Study:

• To present a technique for risk-adjusting inpatient rehabilitation outcomes using functional related groups (FRGs).
• To enable providers to demonstrate value by adjusting length of stay and treatment efficiency for relative risk.
• To offer a practical method for ongoing, updated outcomes analysis.

Main Methods:

• Utilizes functional related groups (FRGs) for risk adjustment of outcomes.
• Involves determining FRG categorization for each patient.
• Compares expected versus actual patient distribution within FRGs to adjust length of stay and efficiency.
• Applicable to providers using Functional Independence Measure (FIM) data, alongside diagnostic and demographic information.

Main Results:

• The described method provides a technique to risk-adjust outcomes, moving beyond unadjusted data.
• Functional Related Groups (FRGs) allow for the adjustment of length of stay and treatment efficiency based on patient risk.
• The analysis can be performed using basic tools like spreadsheets or hand calculators.

Conclusions:

• Risk-adjusted outcomes provide a more accurate reflection of rehabilitation provider efficiency and quality.
• Implementing FRG-based risk adjustment prevents misleading interpretations of outcomes data.
• This technique supports informed decision-making for providers, payers, and consumers in healthcare.
