Final answer:
The Staff Model HMO is the model that hires physicians as salaried employees instead of contracting them.
Step-by-step explanation:
Among the different models of Health Maintenance Organizations (HMOs), the one that hires physicians and pays them a salary, rather than contracting with physicians to create a network of care providers is the Staff Model. In the Staff Model HMO, the healthcare providers are direct employees of the HMO and are paid a fixed salary. This contrasts with other models where HMOs create a network of providers through contracts. The Group Model contracts with a single multi-specialty medical group that provides care to HMO members. The Network Model contracts with more than one medical group or a combination of individual practitioners and groups. Lastly, the Independent Practice Association (IPA) Model HMO contracts with a network of individual doctors who are in private practice to provide services to HMO members at negotiated rates.
