14.1 Primary Health Care Principles & Universal Health Coverage

Primary Health Care Principles & Universal Health Coverage

Primary Health Care (PHC) forms the conceptual, clinical, and operational backbone of the Kenyan health system. For clinical officers preparing for the Clinical Officers Council (COC) Pre-Internship Examination, mastery of PHC principles, international health declarations, and national health financing reforms is essential. Primary health care is not merely first-contact curative relief; it is a whole-of-society approach to health and well-being centered on the needs and preferences of individuals, families, and communities.

1. Historical Evolution: Alma-Ata (1978) to Astana (2018)

The Alma-Ata Declaration (1978)

In September 1978, the International Conference on Primary Health Care convened in Alma-Ata, Kazakhstan (former USSR), co-sponsored by the World Health Organization (WHO) and UNICEF. The conference produced the historic Declaration of Alma-Ata, which famously articulated the global target of 'Health for All by the Year 2000'.

Key tenets of the Alma-Ata Declaration include:

• Health as a Fundamental Human Right: Health is defined not merely as the absence of disease or infirmity, but as a state of complete physical, mental, and social well-being. Attaining the highest possible level of health is a worldwide social goal.
• Gross Health Inequality is Unacceptable: The existing gross inequality in the health status of people, particularly between developed and developing countries as well as within individual nations, is politically, socially, and economically unacceptable.
• Critique of the Hospital-Centric Model: Alma-Ata repudiated the colonial and post-colonial reliance on high-cost, urban-biased, technology-heavy tertiary curative hospitals (the 'tertiary trap'), which consumed the vast majority of national health budgets while leaving rural and peri-urban majorities without basic preventive or curative services.
• Definition of Primary Health Care: Essential health care based on practical, scientifically sound, and socially acceptable methods and technology, made universally accessible to individuals and families in the community through their full participation and at a cost that the community and country can afford to maintain at every stage of their development in the spirit of self-reliance and self-determination.

Comprehensive PHC vs. Selective PHC

Following Alma-Ata, intense debate emerged between two contrasting paradigms:

1. Comprehensive PHC: Championed by Alma-Ata, emphasizing community empowerment, social justice, intersectoral public policy, sanitation, clean water, and political reform to eliminate the root socioeconomic drivers of ill-health.
2. Selective PHC: Introduced at the 1979 Bellagio Conference as an interim, cost-effective compromise. Selective PHC focused strictly on targeted, high-impact clinical interventions known by the acronym GOBI-FFF:
   • G — Growth monitoring (to detect early pediatric undernutrition)
   • O — Oral rehydration therapy (to halt diarrheal mortality)
   • B — Breastfeeding promotion (exclusive breastfeeding for 6 months)
   • I — Immunization (Expanded Programme on Immunization)
   • F — Female education and literacy
   • F — Family spacing (contraception and family planning)
   • F — Food supplementation

While Selective PHC produced rapid reductions in infant mortality, critics noted that vertical, donor-driven disease programs fragmented primary care systems and failed to build resilient, permanent local infrastructure.

The Astana Declaration (2018)

Forty years after Alma-Ata, the Global Conference on Primary Health Care in Astana, Kazakhstan, unanimously adopted the Astana Declaration (2018). Astana reaffirmed the fundamental principles of Alma-Ata while updating PHC for the 21st century:

• Anchor of Universal Health Coverage (UHC): Declared that strengthening PHC is the most inclusive, effective, and cost-efficient vehicle to achieve UHC and the health targets of Sustainable Development Goal 3 (SDG 3).
• Dual Disease Burden: Addressed the escalating global burden of non-communicable diseases (cardiovascular disease, hypertension, type 2 diabetes, cancers) and mental health disorders alongside persistent infectious endemics (HIV, tuberculosis, malaria).
• Primary Care Networks (PCNs): Promoted hub-and-spoke models linking community units and primary clinics with sub-county referral facilities.
• Digital Health: Integrated electronic health records, mobile health (mHealth), and digital decision-support tools into frontline community delivery.

2. The Five Pillars / Core Principles of PHC

Primary Health Care is governed by five cardinal principles that guide the planning, allocation, and delivery of health services:

3. The 8 Essential Elements of PHC (ELEMENTS)

The Alma-Ata Declaration outlined eight fundamental components of Primary Health Care, easily remembered using the classic acronym ELEMENTS:

                                THE 8 PHC ELEMENTS

     [E] ── Education concerning prevailing health problems & prevention methods
     [L] ── Locally endemic disease prevention and vector control
     [E] ── Expanded Programme on Immunization (KEPI) against major infections
     [M] ── Maternal and child health care, including family planning
     [E] ── Essential drugs and medical supplies provision (KEML / KEMSA)
     [N] ── Nutrition promotion and adequate household food supply
     [T] ── Treatment of common diseases, physical trauma, and minor injuries
     [S] ── Safe water supply and basic environmental sanitation (WASH)

Detailed Analysis of the Elements

1. Education on Health Problems (E): Raising community health literacy regarding disease transmission, maternal danger signs, infant feeding, personal hygiene, and lifestyle risk factors. Clinical officers routinely deliver health education during outpatient consultations and child welfare clinics.
2. Locally Endemic Disease Control (L): Targeted surveillance and suppression of geographic endemics. In Kenya, this includes distribution of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) for malaria, mass drug administration (MDA) with albendazole and praziquantel for schistosomiasis and soil-transmitted helminths in the Lake Victoria and Coastal basins, and visceral leishmaniasis (kala-azar) management in ASAL regions.
3. Expanded Programme on Immunization (E): Administering potent, cold-chain-preserved vaccines to eliminate vaccine-preventable child mortality under the Kenya Expanded Programme on Immunization (KEPI) schedule (BCG, OPV/IPV, Pentavalent, PCV-10, Rotavirus, Measles-Rubella, Yellow Fever, HPV).
4. Maternal and Child Health Care (M): Antenatal care (ANC), skilled birth attendance, emergency obstetric and newborn care (EmONC), postnatal care (PNC), cervical cancer screening, and modern contraceptive options (implants, IUCDs, injectables, barrier methods) to reduce maternal and perinatal mortality.
5. Essential Drugs Provision (E): Ensuring continuous availability of safe, efficacious, affordable medicines listed in the Kenya Essential Medicines List (KEML) through the Kenya Medical Supplies Authority (KEMSA) and county distribution networks, prioritized by therapeutic importance.
6. Nutrition Promotion (N): Promoting maternal, infant, and young child nutrition (MIYCN), exclusive breastfeeding for 6 months, growth monitoring, vitamin A supplementation, routine micronutrient fortification, and therapeutic feeding for acute malnutrition.
7. Treatment of Common Ailments and Injuries (T): Primary curative clinical care delivered at dispensaries, health centers, and outpatient departments: managing upper respiratory infections, pneumonia, uncomplicated malaria, urinary tract infections, superficial wounds, burns, and minor orthopedic trauma.
8. Safe Water Supply and Sanitation (S): Improving water, sanitation, and hygiene (WASH) infrastructure: promoting household water treatment (chlorination, filtration, boiling), construction of Ventilated Improved Pit (VIP) latrines, handwashing stations with soap, and safe medical waste disposal.

Expanded PHC in Kenya: Modern Kenyan health policy explicitly expands these original eight elements to include mental health care integration, non-communicable disease (NCD) screening and management (hypertension, diabetes), gender-based violence (GBV) survivor support, and primary oral and ophthalmic care.

4. Universal Health Coverage (UHC) in Kenya & Health Financing Reforms

Constitutional Foundation & The UHC Cube

Article 43(1)(a) of the Constitution of Kenya 2010 explicitly guarantees that:

"Every person has the right to the highest attainable standard of health, which includes the right to health care services, including reproductive health care."

Universal Health Coverage implies that all individuals and communities receive the health services they need—promotive, preventive, curative, rehabilitative, and palliative—of sufficient quality to be effective, without exposing the user to financial hardship.

In Kenya, out-of-pocket (OOP) healthcare expenditures historically accounted for over 30% to 40% of total health expenditure. Out-of-pocket spending is the most regressive and inequitable financing mechanism: catastrophic health events routinely plunged hundreds of thousands of Kenyan families into absolute poverty annually due to the sale of productive assets, distress borrowing, or detention in hospitals over unpaid bills.

The 2023 Healthcare Financing Transformation

In October 2023, the Government of Kenya enacted four transformative health statutes that fundamentally overhauled the national health architecture:

1. The Primary Health Care Act, 2023: Institutionalized Primary Care Networks (PCNs) and formally recognized Community Health Promoters (CHPs) with standardized stipends and operational kits.
2. The Social Health Insurance Act, 2023: Repealed the National Hospital Insurance Fund (NHIF) Act of 1998 and established the Social Health Authority (SHA).
3. The Digital Health Act, 2023: Mandated a unified national digital health ecosystem, centralized patient health records, and the electronic Community Health Information System (eCHIS).
4. The Facilities Improvement Financing (FIF) Act, 2023: Provided legal mechanisms enabling public health facilities to retain and reinvest revenue generated from clinical services, halting the sweeping of facility collections into County Revenue Funds.

The Structural Shift: NHIF to Social Health Authority (SHA)

The historical National Hospital Insurance Fund (NHIF) suffered from critical structural flaws: it disproportionately catered to the formal employment sector (which constitutes less than 20% of Kenya's working population), relied on voluntary informal sector enrollment characterized by adverse selection and high attrition rates, provided minimal coverage for outpatient primary care, and struggled with unsustainable claims ratios for private tertiary facilities.

The Social Health Authority (SHA) manages three distinct, statutory, ring-fenced funds designed to pool risk progressively and provide comprehensive coverage across all six levels of healthcare delivery:

                         SOCIAL HEALTH AUTHORITY (SHA)

  • Outpatient primary care   • Secondary & tertiary care    • Dialysis, kidney transplant,
  • 100% FREE at point of use   at Level 4, 5, 6 hospitals     oncology & radiation

The Three Statutory Funds under SHA

1. Primary Healthcare Fund (PHCF)

• Financing Source: Fully exchequer-funded through government tax revenues; does not require individual household contributions.
• Covered Facilities: Level 2 (Dispensaries) and Level 3 (Health Centres), including linked Level 1 community units.
• Benefit Package: Universal, comprehensive outpatient primary health care services: clinical consultations, preventive screenings, antenatal care, basic diagnostic laboratory tests, and essential medicines from the Kenya Essential Medicines List.
• Reimbursement Mechanism: Directly reimburses contracted primary facilities via risk-adjusted capitation, eliminating point-of-care co-payments or user fees for any Kenyan citizen.

2. Social Health Insurance Fund (SHIF)

• Financing Source: Progressive statutory contributions. Formal sector employees contribute 2.75% of their gross monthly income (without an upper ceiling, ensuring progressive cross-subsidization). Informal sector and self-employed households contribute an annualized premium determined through standardized socioeconomic means-testing proxy tools. The National and County governments pay contributions on behalf of certified indigent and vulnerable households.
• Covered Facilities: Contracted Level 4 (Sub-County Hospitals), Level 5 (County Referral Hospitals), and Level 6 (National Referral Hospitals).
• Benefit Package: Inpatient admissions, general and specialized surgical procedures, maternal and neonatal inpatient care, diagnostic imaging (ultrasound, X-ray, CT scan, MRI), adult and pediatric specialty consultations, and pharmacy benefits according to authorized clinical management guidelines.

3. Emergency, Chronic and Critical Illness Fund (ECCIF)

• Financing Source: Centrally funded through exchequer allocations, statutory levies, and strategic health development partnerships.
• Purpose & Safety Net Function: Designed specifically to eliminate catastrophic medical expenditure for high-cost or life-threatening conditions once SHIF benefit ceilings are exhausted or during uninsured acute medical crises.
• Covered Clinical Indications:
  • Emergency Care: Immediate stabilization, resuscitation, and critical emergency surgery for polytrauma, acute stroke, acute myocardial infarction, and severe burns (fulfilling Article 43(2) of the Constitution: "A person shall not be denied emergency medical treatment").
  • Critical Illness: Extended Intensive Care Unit (ICU) and High Dependency Unit (HDU) care beyond standard SHIF inpatient limits.
  • Chronic Catastrophic Diseases: End-stage renal disease (hemodialysis, peritoneal dialysis, and kidney transplantation workup), comprehensive oncology treatments (chemotherapy regimens, external beam radiotherapy, brachytherapy, surgical oncology), and chronic palliative care.
