Why is organizational integration important?

Rationale:

A. Car model: The "Car model" is not a recognized model of Health Maintenance Organization (HMO). It seems to be a distractor in this context.

B. Network model: In the network model, the HMO contracts with multiple independent medical groups or practices to provide healthcare services to its members.

C. Group model: In the group model, the HMO contracts with a single medical group, which employs physicians and provides healthcare services to HMO members.

D. Staff model: In the staff model, the HMO directly employs physicians and other healthcare providers who deliver services to its members.

Rationale:

A. Private long-term care insurance: While private long-term care insurance can help cover the costs of nursing home care for individuals who have purchased policies, it is not the largest source of financing for nursing home care.

B. Medicaid: Medicaid is the largest source of financing for nursing home care in the United States. It provides coverage for low-income individuals who meet eligibility criteria, including coverage for long-term care services such as nursing home care.

C. Medicare: While Medicare provides limited coverage for skilled nursing facility care following a hospital stay, it is not the largest source of financing for nursing home care overall.

D. Private out-of-pocket payments: Private out-of-pocket payments, including payments made by individuals or their families, contribute to financing nursing home care but are typically not as significant as Medicaid.
