Health systems provide the structural framework through which health services are delivered to communities. For community health professionals in Kenya, understanding the core components that constitute a health system is essential to effectively participate in planning, management, and improvement of health outcomes. This chapter introduces the six health system building blocks as defined by the World Health Organization, contextualizing their meaning and relevance in Kenya’s community health settings. Mastery of these concepts enables practitioners to engage critically with health system challenges and contribute to sustainable health service delivery.

4.1 Definition of Terms

In this section, we clarify key terminology related to health system building blocks. Precise understanding of these terms equips community health workers to navigate and influence the health system effectively.

4.1.1 Health System

The term health system refers to all organizations, people, and actions whose primary intent is to promote, restore, or maintain health. In Kenya, this includes public and private healthcare providers, regulatory bodies, financing mechanisms, and the communities themselves. The health system is not limited to hospitals and clinics but extends to policy frameworks, supply chains, and health information networks that collectively influence health outcomes.

Characteristics of a Health System

• Comprehensive scope: Encompasses preventive, curative, rehabilitative, and palliative services, ensuring holistic care across the life course.
• Multi-sectoral involvement: Includes government ministries, non-governmental organizations, community groups, and private sector players working collaboratively.
• Resource mobilization and allocation: Involves financing, workforce deployment, and infrastructure development tailored to population health needs.
• Regulatory framework: Governed by policies, laws, and standards that ensure quality, equity, and accountability.
• Community participation: Recognizes the role of individuals and communities in shaping priorities and accessing care.

Kenya’s community health strategy integrates these components to improve access and equity, particularly in rural and marginalized areas where formal health facilities are distant.

4.1.2 Health System Building Blocks

The six health system building blocks are fundamental components identified by the World Health Organization to describe and analyze the structure and function of health systems. These blocks serve as a framework for health system strengthening and performance improvement.

The Six Building Blocks

• Service Delivery: The provision of effective, safe, and quality health interventions to those who need them, when and where needed.
• Health Workforce: All people engaged in actions whose primary intent is to enhance health, including community health workers, nurses, doctors, and administrators.
• Health Information Systems: Mechanisms for collecting, analyzing, and disseminating health data to support decision making at all levels.
• Access to Essential Medicines: Ensuring the availability, affordability, and appropriate use of medicines and health technologies.
• Health Financing: The mobilization, accumulation, and allocation of funds to cover the health needs of the population.
• Leadership and Governance: The oversight, policy guidance, regulation, and accountability mechanisms that direct the health system.

In Kenyan community health, these blocks interrelate to support service delivery at the grassroots, for example through community health volunteers’ linkages with health facilities.

4.1.3 Service Delivery

Service delivery refers to the manner in which health services are organized and provided to communities. It is the frontline of the health system where policies and resources translate into patient care.

Essential Elements of Service Delivery

• Accessibility: Services must be physically and financially reachable by all population segments, including those in remote areas.
• Quality: Care should meet established standards for safety, effectiveness, and patient-centeredness.
• Continuity: Health services should be consistent and coordinated across different levels and over time.
• Comprehensiveness: Includes preventive, promotive, curative, rehabilitative, and palliative care.
• Equity: Services should be distributed fairly, addressing disparities related to socio-economic status, geography, or other factors.

4.1.4 Health Workforce

The health workforce encompasses all individuals who deliver health services and support functions. In community health, this includes both formally trained professionals and community health volunteers who provide essential outreach.

Key Aspects of the Health Workforce

• Adequate numbers: Sufficient personnel to meet population health needs without excessive workload.
• Competency: Appropriate skills and knowledge to deliver quality care, maintained through continuous education.
• Distribution: Equitable allocation of workers across urban and rural areas to reduce service gaps.
• Motivation: Incentives, recognition, and supportive working conditions that encourage retention and performance.
• Regulation: Licensing, ethical standards, and supervision to ensure professionalism and accountability.

In Kenyan community health, challenges like attrition of community health volunteers highlight the importance of motivation and support mechanisms.

4.1.5 Health Information System

A health information system collects, processes, and disseminates data required for health decision-making. Reliable data allows managers and policymakers to plan, monitor, and evaluate health programs.

Functions of Health Information Systems

• Data collection: Routine gathering of information on health status, service utilization, and resource availability.
• Data management: Organizing and storing data securely for easy retrieval.
• Analysis and interpretation: Transforming raw data into meaningful insights for action.
• Dissemination: Sharing information with stakeholders at all levels, from community health workers to national planners.
• Use of information: Applying evidence to improve quality, allocate resources, and respond to health needs.

4.1.6 Access to Essential Medicines

Access to essential medicines means that people receive the medicines they need, in appropriate doses, at affordable prices, and without undue delay. This is vital for effective treatment and disease control.

Dimensions of Access to Medicines

• Availability: Medicines must be in stock at health facilities and community outlets.
• Affordability: Costs should not prevent individuals from obtaining necessary medicines.
• Quality assurance: Medicines must meet safety and efficacy standards.
• Rational use: Appropriate prescribing and dispensing to avoid misuse and resistance.
• Supply chain management: Efficient procurement, storage, and distribution systems to prevent stock-outs.

Community health workers often support medicine adherence and report stock levels to improve supply chain responsiveness.

4.1.7 Health Financing

Health financing involves mobilizing and managing funds to ensure that health services are accessible and affordable. It influences the sustainability and equity of the health system.

Core Functions of Health Financing

• Revenue collection: Gathering funds from taxes, insurance premiums, or user fees.
• Pooling of resources: Combining funds to spread financial risks across populations.
• Purchasing: Allocating funds to providers based on agreed priorities and performance.
• Financial protection: Shielding individuals from catastrophic health expenditures.
• Equity: Ensuring that financing mechanisms do not disproportionately burden the poor.

Kenya’s National Hospital Insurance Fund (NHIF) plays a significant role in pooling resources and providing financial protection for community members.

4.1.8 Leadership and Governance

Leadership and governance refer to the stewardship and oversight that ensure the health system functions effectively and ethically. This building block ensures accountability and strategic direction.

Dimensions of Leadership and Governance

• Policy formulation: Developing clear health policies and strategic plans.
• Regulation and enforcement: Establishing standards and ensuring compliance.
• Coordination: Harmonizing activities among multiple stakeholders.
• Accountability mechanisms: Transparent monitoring and evaluation processes.
• Community engagement: Involving citizens in decision-making and feedback.

In Kenya, county health management teams exemplify governance by coordinating community health services, overseeing resource use, and engaging local leaders.
