What Are Health Care Services?
Health care services refer to organized medical, preventive, diagnostic, therapeutic, and rehabilitative services provided to individuals and communities to promote, maintain, monitor, and restore health. These services can be delivered through hospitals, clinics, health centers, and even through home-based care.
They play a critical role in:
- Preventing illnesses before they become severe
- Treating health conditions effectively and efficiently
- Improving the quality of life for patients with chronic diseases
- Reducing the burden on the economy by maintaining a healthier workforce
For a formal definition, the World Health Organization (WHO) provides comprehensive guidelines on how health systems should be structured for optimal outcomes.

- Management of common illnesses such as colds, minor infections, and mild injuries
- Basic diagnostics like blood pressure measurement, sugar tests, and basic lab investigations
