UK screening programmes - Free UK Medical PG Review

Quick Overview

The UK NHS offers population-based screening programmes targeting conditions where early detection improves outcomes. Programmes cover cancer (bowel, breast, cervical, AAA), antenatal/newborn, and adult vascular risk. Understanding age criteria, intervals, and referral thresholds is essential for GP practice and patient counseling per NICE PH16 guidelines.

Core Facts & Concepts

Cancer Screening Programmes

Programme	Age Range	Interval	Method	Referral Threshold
Cervical	25-64 years	25-49: 3-yearly 50-64: 5-yearly	HPV primary testing	HPV+ with cytology abnormality → colposcopy
Breast	50-71 years	3-yearly	Mammography (2 views)	Suspicious lesion (R4/R5) → 2-week wait
Bowel	60-74 years	2-yearly	FIT (Faecal Immunochemical Test)	≥120 μg Hb/g faeces → colonoscopy
AAA	Men 65 years	One-off	Abdominal ultrasound	≥5.5cm → vascular referral

Antenatal Screening

Infectious diseases (booking): HIV, syphilis, hepatitis B, rubella immunity
Fetal anomaly scan: 18-20+6 weeks (11 structural conditions)
Down syndrome screening:
- Combined test (11-14 weeks): nuchal translucency + βhCG + PAPP-A
- Quadruple test (14-20 weeks): if missed combined
- Risk ≥1:150 → offer invasive testing (amniocentesis/CVS)
Sickle cell/thalassaemia: universal at booking

Newborn & Child Screening

Newborn blood spot (day 5): 9 conditions including PKU, MCADD, sickle cell, CF, hypothyroidism
Newborn hearing: automated otoacoustic emissions (AOAE) within 4-5 weeks
Newborn physical examination: within 72 hours + 6-8 weeks (hips, heart, eyes, testes)

⭐ Clinical Pearl: FIT replaced guaiac-based FOBt in 2019 - more sensitive and doesn't require dietary restriction

Problem-Solving Approach

Screening Eligibility Assessment

Verify age criteria: Automatic invitations sent; manual checks for new registrations
Identify exclusions:
- Cervical: total hysterectomy for benign disease (if cervix removed)
- Breast: symptomatic patients → 2-week wait, NOT screening
- Bowel: active IBD, previous CRC → surveillance colonoscopy instead
- AAA: women not screened (low prevalence); known AAA → surveillance
Document informed choice: Screening is voluntary; record acceptance/decline
Manage abnormal results:
- Cervical HPV+/cytology abnormal → colposcopy within 6 weeks
- Breast recall (R3-R5) → assessment clinic within 3 weeks
- FIT positive → colonoscopy within 2 weeks
- AAA 3.0-4.4cm → annual USS; 4.5-5.4cm → 3-monthly USS

Red Flags - Screening Inappropriate 🚩

Symptoms present → diagnostic pathway, NOT screening
High-risk individuals → intensified surveillance (e.g., Lynch syndrome)
Life expectancy <5 years → discuss risks/benefits

Analysis Framework

Screening vs Surveillance vs Diagnosis

Feature	Screening	Surveillance	Diagnosis
Population	Asymptomatic, average risk	High-risk/previous disease	Symptomatic
Pathway	Invitation-based	Specialist-led protocol	2-week wait/urgent
Example	FIT at age 62	Annual colonoscopy (Lynch)	Rectal bleeding → sigmoidoscopy

Wilson-Jungner Screening Criteria (applied to NHS programmes)

Condition: important, understood natural history, detectable latent phase
Test: acceptable, valid (sensitive/specific), agreed threshold
Treatment: effective intervention, agreed policy on whom to treat
Programme: cost-effective, continuous process, quality-assured
