Case-mix reimbursement for nursing home services: simulation approach

Area of Science:

• Health Services Research
• Healthcare Economics
• Gerontology

Background:

• Nursing home reimbursement is increasingly shifting towards case-mix models.
• Several US states are adopting or considering case-mix reimbursement.
• Evaluating the impact of these systems on nursing homes is crucial.

Purpose of the Study:

• To develop and apply a method for evaluating case-mix reimbursement systems for Connecticut nursing homes.
• To compare potential outcomes of different state-specific case-mix models against Connecticut's current system.

Main Methods:

• A simulation model was developed to replicate payment structures.
• Payments were simulated using case-mix systems from Maryland, Ohio, and West Virginia.
• The model assessed the relationship between payments and patient needs.

Main Results:

• The studied case-mix systems demonstrated a better correlation between payments and patient needs compared to Connecticut's current system.
• For-profit nursing homes showed a relative financial advantage over nonprofit homes under these models.
• The Ohio system projected the highest additional costs, while the West Virginia system appeared less expensive for direct patient care.

Conclusions:

• Case-mix reimbursement systems offer improved alignment of payments with nursing home patient acuity.
• Implementation of specific case-mix models may create financial disparities between for-profit and nonprofit facilities.
• Policymakers should carefully consider the cost implications and distributional effects of different case-mix methodologies.
