PHC Framework and Saudi Context

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Primary Health Care (PHC) rests on the WHO-Alma-Ata (1978) pillars: accessibility, equity, community participation, intersectoral action, and appropriate technology.
The five core PHC functions in Saudi family practice are continuity, comprehensiveness, coordination, first-contact accessibility, and community orientation.
Levels of prevention (Leavell & Clark): primordial (address risk factors of risk factors), primary (vaccination, counselling), secondary (screening, early detection), tertiary (limit complications), and quaternary (protect from over-medicalisation).
Screening must satisfy Wilson & Jungner criteria before adoption; Saudi national programs include newborn, premarital, breast, colorectal, and hypertension/diabetes risk screening.
High-yield formulas: BMI = kg/m²; MAP = (2·DBP + SBP)/3; NNT = 1/ARR; eGFR (CKD-EPI 2021, race-free) uses sex-specific κ and α.
Ramadan fasting in diabetic patients requires pre-Ramadan assessment (CREED criteria) and structured SMBG.

PHC Framework and Saudi Context

The Alma-Ata Declaration defined PHC as essential care made universally accessible through community participation. In Saudi Arabia, the Vision 2030 Health Sector Transformation re-organised care around the Model of Care (MoC), emphasising PHC centres as the population’s first contact. The MoH tiered referral flows from PHC → general hospital → tertiary/specialised centre, with the family physician acting as gatekeeper.

Levels of Prevention

Level	Goal	Family-practice example
Primordial	Prevent emergence of risk factors	School-based anti-tobacco policy
Primary	Reduce incidence	MMR vaccination, smoking cessation
Secondary	Early detection	Biennial mammogram 40–74 (MoH)
Tertiary	Reduce complications	Diabetic foot clinic, cardiac rehab
Quaternary	Avoid over-medicalisation	Limiting unnecessary antibiotics

Consultation Models

Calgary–Cambridge: 73 skills across initiating, gathering, physical exam, explaining, closing.
Patient-Centred Clinical Method (Stewart): explore illness experience, understand the whole person, find common ground, incorporate prevention, strengthen the doctor–patient relationship.
Pendleton: seven tasks that include the patient’s ideas, concerns, and expectations (ICE).

Chronic Disease Quick Reference

Diabetes (Saudi MoH 2024): HbA1c target <7 % for most adults; mean glucose = 28.7 × HbA1c − 46.7 mg/dL.
Hypertension: diagnose at ≥140/90 mmHg clinic (or ≥135/85 home); use MAP = (2·DBP + SBP)/3 for haemodynamic assessment.
Asthma: stepwise GINA; assess control with ACT, inhaler technique at every visit.
Obesity: BMI ≥25 (overweight), ≥30 (obese) in Saudi adults; add waist circumference (>102 cm men, >88 cm women).

Exam trap: vaccination is primary, not secondary, prevention; HbA1c reflects the prior 8–12 weeks; BMI alone misses sarcopenic obesity.

Applying Wilson & Jungner in the Saudi Setting

Before adopting any screening test, verify: the condition is an important health problem; there is an accepted treatment; facilities for diagnosis and treatment exist; a recognisable latent or early stage is identifiable; a suitable, valid, acceptable test is available; the natural history is understood; an agreed policy on whom to treat exists; the cost is economically balanced; and screening is a continuous process, not a one-off project. The Saudi MoH national programs — newborn (17 disorders), premarital (thalassaemia, sickle cell, HCV, HBV), breast (mammography 40–74 biennial), colorectal (FIT 45–74), and hypertension/diabetes risk (annual BP, BMI, glycaemia in high-risk groups) — all satisfy these criteria at a population level.

Chronic Care Model and Self-Management

Wagner’s Chronic Care Model links six elements: community resources, health system, self-management support, delivery system design, decision support, and clinical information systems. In practice, the family physician activates SMART goals (Specific, Measurable, Achievable, Relevant, Time-bound), confirms understanding with the teach-back method, and uses the Saudi Healthy Plate 2024 (½ vegetables/fruits, ¼ lean protein, ¼ whole grains, plus water and 2–3 cups of laban) for culturally specific counselling.

Cultural Competency and Ramadan

Pre-Ramadan risk stratification for diabetic patients follows the CREED mnemonic (Consultation, Risk evaluation, Education, Exercise, Diet/Drug adjustment). The IDF-DAR risk calculator places patients into low/moderate/high categories; high-risk patients should be advised against fasting. The MoH Ramadan Health Encyclopedia provides patient leaflets in Arabic and English.

Common Mistakes and Exam Strategy

Mixing up ARR vs RRR inflates apparent treatment effect; NNT = 1/ARR only when ARR is a decimal proportion.
The CKD-EPI 2021 race-free equation removes the race coefficient used pre-2021; the 2009 MDRD is no longer recommended in adults.
Continuity ≠ comprehensiveness: continuity spans time, comprehensiveness spans health problems.
Family APGAR is a screening tool for family dysfunction, not a diagnostic instrument.

Practice Prompts

A 52-year-old Saudi man with T2DM (HbA1c 8.1 %, eGFR 72) wants to fast Ramadan. Outline a structured pre-Ramadan plan including SMBG targets, medication adjustment (metformin + gliclazide MR), and red-flag symptoms requiring breaking the fast.
A 45-year-old asymptomatic woman asks about colorectal screening. Apply Wilson & Jungner to justify the Saudi FIT-based program, then list counselling points on test interpretation (≥10 µg Hb/g faeces = positive) and follow-up colonoscopy pathway.
