Which of the following terms is associated with the length of time a patient stays within a bundled payment system?

The correct association in this context is with the per diem rate. This term specifically refers to the daily rate for reimbursement, which is instrumental in bundled payment systems where the total payment for care, which can include multiple services and components, is predetermined based on the length of stay.

In a bundled payment model, healthcare providers are compensated for a variety of services surrounding a specific treatment or condition over a fixed period, and the per diem rate helps manage the costs associated with patient care for each day they are hospitalized. This system encourages healthcare facilities to provide efficient care while keeping the patient's length of stay in mind, economically incentivizing shorter stays without compromising the quality of care.

On the other hand, a global budget refers to an overall budget for a facility or system and is not specific to the length of stay for an individual patient. A capitated rate is a payment model where providers receive a set amount for each enrolled patient regardless of how many services the patient uses, which does not directly relate to the duration of a stay in the same manner. Durational cost, while it may imply a relationship with time, is not a standard term used in healthcare reimbursement systems and does not accurately describe the financial structure involved in bundled payments.
