Structure and Services

Financing

• Primary Care: This is the first point of contact for patients within the healthcare system. Primary care physicians provide preventive care, diagnose and treat common illnesses, and manage chronic conditions.

• Secondary Care: This level of care involves specialists who provide more advanced diagnosis and treatment for specific medical conditions. Patients are typically referred to specialists by their primary care physician.

• Tertiary Care: This is the highest level of care, provided by specialized hospitals and medical centers equipped to handle complex medical cases, such as major surgeries or critical illnesses.

The healthcare industry is a major consumer of resources, and healthcare spending is a significant portion of many countries’ GDP (Gross Domestic Product). Healthcare can be financed through various means, including:

• Public funding: This comes from government taxes and is used to finance public healthcare programs and provide healthcare to specific populations.
• Private health insurance: This is a system where individuals or employers pay premiums to a health insurance company that covers a portion of their medical expenses.
• Out-of-pocket payments: This refers to the amount of money that patients pay directly for their medical care, not covered by insurance.
