Every cohort has candidates who can discuss an obscure endocrine disorder in detail and cannot say when colorectal cancer screening starts. The exam is built the other way round. Prevention and health promotion carry real blueprint weight, the content is finite, and it is the most reliably scoreable material on either exam.
Verify against the current source
Screening recommendations are revised regularly, and certifying bodies update items on their own cycle. Use this as a framework and confirm specifics against the current USPSTF recommendations, CDC immunisation schedules and relevant specialty guidance for your exam date.
The definitional item you will almost certainly see
| Level | Goal | Examples |
|---|---|---|
| Primary | Prevent disease before it occurs | Immunisation, seat belts, smoking cessation counselling in a non-smoker's child, folic acid before conception |
| Secondary | Detect disease early, while asymptomatic | Mammography, colonoscopy, blood pressure screening, Pap testing |
| Tertiary | Limit disability and complications in established disease | Cardiac rehabilitation, diabetic foot care, stroke rehabilitation |
The trap is that the same intervention changes level depending on the patient. A statin in someone with no cardiovascular disease is primary prevention; the same statin after a myocardial infarction is tertiary. Read who the patient is, not just what the intervention is.
USPSTF grades
| Grade | Meaning | Action |
|---|---|---|
| A | High certainty of substantial benefit | Offer or provide |
| B | High certainty of moderate benefit, or moderate certainty of moderate to substantial benefit | Offer or provide |
| C | Small net benefit | Offer selectively, based on individual circumstances |
| D | No net benefit, or harms outweigh benefits | Discourage |
| I | Insufficient evidence | Evidence does not support a recommendation either way |
Grade D is the one candidates forget, and it is a favourite distractor. A D recommendation is not neutral — it means the correct answer is not to screen, and an option offering the test is wrong even though it sounds thorough.
The framework, applied
For every screening topic, answer four questions in order. Learning the shape is more durable than memorising isolated ages.
- Who — which population, defined by age, sex, risk factors or exposure?
- When does it start?
- How often, and with which test?
- When does it stop, and what makes it stop early — life expectancy, comorbidity, prior results?
Adult screening topics that recur
- Blood pressure. Screening in adults, with confirmation outside the clinical setting before diagnosing hypertension. Expect an item where the correct answer is repeat or ambulatory measurement rather than starting a drug.
- Colorectal cancer. Average-risk screening now begins earlier than the figure many clinicians learned in training, continues to the mid-seventies, and becomes an individualised decision after that. Multiple acceptable modalities exist; a positive stool-based test requires diagnostic colonoscopy, not a repeat stool test.
- Breast cancer. Know the current recommended starting age, the interval and the upper age boundary, and the distinction between average and elevated risk.
- Cervical cancer. Cytology alone in the twenties; cytology, high-risk HPV testing or co-testing from thirty, at longer intervals. Screening generally ends in the mid-sixties with an adequate negative history. HPV vaccination status does not stop screening.
- Lung cancer. Annual low-dose CT for adults in the specified age band with a sufficient pack-year history who currently smoke or quit within the past fifteen years.
- Abdominal aortic aneurysm. A one-time ultrasound in men aged 65–75 who have ever smoked.
- Diabetes. Screening for prediabetes and type 2 diabetes in adults in the specified age range who are overweight or obese.
- Lipids and statin therapy. Risk-based, using estimated cardiovascular risk rather than cholesterol alone.
- Osteoporosis. Women 65 and older, and younger postmenopausal women whose fracture risk is comparable.
- Depression and anxiety. Screening in adults including pregnant and postpartum patients, with adequate systems for diagnosis and follow-up.
- Infectious disease. HIV, hepatitis C, hepatitis B in those at increased risk, latent tuberculosis in increased-risk populations, and sexually transmitted infection screening by risk.
- Behavioural. Tobacco use with cessation intervention, and unhealthy alcohol use with brief counselling.
- Intimate partner violence. Screening women of reproductive age, with the correct answer usually being a private, direct enquiry.
- Prostate cancer. An individual shared decision within a defined age band; screening is not recommended above it.
Where the distractors live
Wrong options in this domain are usually plausible-sounding tests that are graded D or I: routine screening for ovarian, pancreatic, testicular or thyroid cancer in asymptomatic adults, or carotid artery stenosis screening in the general population. "Order more tests" is not a safe default in prevention items.
Counselling and behaviour change
Health promotion items reward motivational interviewing over instruction. The pattern of the correct answer is consistent: it explores the patient's own view rather than delivering information they did not ask for.
Know the stages of change — precontemplation, contemplation, preparation, action, maintenance — and match the intervention to the stage. A patient in precontemplation who is handed a quit date is being mismanaged; the correct response raises the topic and explores ambivalence. The five A's for tobacco (ask, advise, assess, assist, arrange) is another framework worth having ready.
Immunisation
Vaccine schedules change annually, so learn the structure and check the current schedule close to your exam date:
- Which vaccines are live, and therefore avoided in pregnancy and significant immunosuppression.
- Catch-up principles — an interrupted series is resumed, not restarted.
- True contraindications versus common false ones. Mild illness, low-grade fever and a family history of reactions are not contraindications, and items test exactly that.
- Adult vaccines by age and by risk condition, including those tied to specific chronic diseases.
Why this domain is worth the hours
It is finite, it is published, and it is predictable. Nobody enjoys memorising screening intervals, which is precisely why they are the points other candidates leave on the table while chasing a rare diagnosis worth a single item. Two focused sessions on this material will do more for your score than a week spent on zebras.
Key points
- Learn the framework — who, starting when, how often, until when — rather than isolated numbers.
- USPSTF grades A and B are the ones to know; grade D means actively do not screen.
- Primary, secondary and tertiary prevention appear as a definitional item almost every time.
- Guidelines change; study the version current for your exam date and verify against the source.
