Final answer:
The statement that 'To determine length of stay' does not describe a purpose of performing the Minimum Data Set (MDS), which is used for assessing residents in nursing homes to develop care plans and determine reimbursement, not length of stay.
Step-by-step explanation:
The statement that does not describe a purpose of performing the Minimum Data Set (MDS) is: To determine length of stay. The MDS is a standardized assessment tool used primarily in the United States by nursing homes and long-term care facilities to assess the functional capabilities of residents. Its purposes include conducting a comprehensive assessment of each resident's functional capabilities and their needs to develop an individualized plan of care, determining the level of reimbursement from Medicare or Medicaid, and the assessment can certainly affect the reimbursement due to the resident's health care needs. However, it does not directly determine the length of stay for patients, as length of stay is dependent on individual patient needs and treatment regimens.
