DOccMed

The DOccMed
A clear, structured route through the Diploma in Occupational Medicine (DOccMed) — the Faculty of Occupational Medicine’s qualification for doctors practising occupational health. Here is what the exam involves, and the question bank we have built to revise for it. It covers the two-report portfolio and the 20-minute oral as well as the MCQ, so the whole diploma is prepared in one place.
This is one of our GP Diplomas — qualifications GPs commonly add to their portfolio. The DOccMed is taken by GPs offering occupational health and by doctors entering the specialty. Its multiple-choice paper is the same paper as the Part 1 MFOM, with the same question sets and one pass mark, so this bank serves both.
A best-fit MCQ paper, plus a portfolio & viva
The DOccMed has two parts: an online multiple-choice paper, and a portfolio of two written reports defended at a short oral viva. This question bank revises the MCQ paper; our companion guide covers the portfolio and viva.
The DOccMed syllabus
Twelve themed areas spanning the FOM core syllabus. Our question bank covers every one — an average of about 83 questions per module (83–84 each), 1,000 in total.
Everything for the exam, in one place
The same engine that powers our AKT and MSRA revision, focused on the DOccMed. Our questions are written and reviewed by clinicians and re-audited against current guidance, with corrections logged and dated.

“Occupational medicine rewards applying a framework, not reciting limits. For almost any question, ask: is this person fit for the role, with or without adjustments; is the condition work-related; what surveillance or reporting does the law require; and what do I tell the employer versus the employee? Get those reflexes and the paper feels familiar.”Dr Victoria Hammond, Co-Founder & Lead for Educational Design (MBBS, BSc (Hons))

Question 1 of 10
Biological Hazards: a new haematology nurse with no chickenpox history
Scenario: A 26-year-old nurse joining a haematology unit reports no recollection of ever having had chickenpox or shingles and has no record of varicella vaccination. As the OH physician you are aware she will have direct contact with severely immunocompromised patients. You consider how to establish her varicella status and what to advise if she is found to be susceptible.
Question: What is the most appropriate occupational health management of her varicella status?
Pick an answer to reveal the explanation.
The correct answer is B. Check varicella-zoster antibody status; if she is seronegative (susceptible), offer varicella vaccination.
Core Lens: High-Yield Takeaways
- No clear history → check serology — an HCW with no definite history of chickenpox or shingles and no vaccination record should have varicella-zoster virus (VZV) antibody status checked rather than being assumed immune.
- Seronegative → offer vaccine — a worker found to be VZV-seronegative (susceptible) should be offered varicella vaccination: two doses 4–8 weeks apart (Green Book chapter 34).
- Susceptibility matters most around the vulnerable — on a haematology unit her contact with severely immunocompromised patients makes establishing and correcting susceptibility especially important.
- Prophylaxis is for after a real exposure, not routine cover — post-exposure prophylaxis has a place after a significant exposure in specific susceptible high-risk individuals, not as routine pre-placement cover; since September 2024 intramuscular VZIG has not been available in the UK, and oral antivirals are now first line (UKHSA).
- Right vaccine, right course — a susceptible worker needs two doses of varicella vaccine, not a single dose and not a shingles (zoster) vaccine, which is designed to reduce reactivation in people already infected.
Chemical hazards: reproductive toxins and advice for workers planning pregnancy
Scenario: A 29-year-old laboratory worker tells you she and her partner are planning to start a family and is worried about a solvent she handles that is labelled as a reproductive toxin. She is not yet pregnant. Her manager has said that protections only apply once she formally notifies the company that she is pregnant. She asks what should happen now.
Question: What is the most appropriate occupational-health advice regarding her exposure to this reproductive toxin?
Pick an answer to reveal the explanation.
The correct answer is C. Assess and control exposure under COSHH now for all exposed workers, minimising hers before any pregnancy.
Core Lens: High-Yield Takeaways
- Control comes first and applies now — reproductive toxins are substances hazardous to health, so under COSHH exposure must be assessed and adequately controlled for all exposed workers irrespective of whether anyone is pregnant.
- The risk is not confined to confirmed pregnancy — reproductive toxicity can affect fertility and the earliest, often unrecognised, weeks of pregnancy, so waiting for a formal pregnancy notification leaves the most vulnerable period unprotected.
- MHSWR adds a specific new-and-expectant-mother duty — the Management of Health and Safety at Work Regulations already require the general risk assessment to cover risks to new and expectant mothers wherever women of child-bearing age are employed (regulation 16(1)), and once an employer is notified of a pregnancy they require a specific risk assessment and, if risks cannot be avoided, adjustment of conditions or hours, suitable alternative work, or suspension on full pay; but this supplements, and does not replace, the underlying COSHH duty.
- Reproductive toxins can affect men too — some agents impair male fertility, so advice and control are not solely a female issue.
Overseas posting: the fitness-to-travel assessment
Scenario: A 49-year-old engineer is being posted for 12 months to a remote site in a tropical, malaria-endemic region with limited local healthcare. He has well-controlled type 2 diabetes on oral medication and takes a statin. The employer asks OH to carry out a pre-placement fitness-to-travel assessment and to advise what should be addressed before deployment.
Question: What should the pre-placement fitness-to-travel assessment for this overseas posting most appropriately focus on?
Pick an answer to reveal the explanation.
The correct answer is B. His fitness for this posting: diabetes care abroad, vaccines, malaria prophylaxis and evacuation plans.
Core Lens: High-Yield Takeaways
- Fitness to travel is destination- and role-specific — the assessment is not a generic “fit today” snapshot; it weighs the worker’s health against where they are going, for how long, and what healthcare is available there.
- Chronic conditions are managed, not disqualifying — well-controlled type 2 diabetes does not bar an overseas posting; the question is whether it can be safely maintained at the destination (medication supply, storage, monitoring, escalation if it destabilises).
- Cover the predictable travel risks — vaccinations appropriate to the region, malaria chemoprophylaxis for an endemic area, and advice on food/water, heat and access to care.
- Plan for things going wrong — in a remote area with limited healthcare, contingency and medical-evacuation arrangements are part of a competent assessment.
Law & Ethics: a worker who removes a machine guard
Scenario: During an OH workplace visit a worker is seen removing the guard from a machine to work faster and ignoring the respirator provided for a dusty task. A supervisor asks whether health-and-safety duties rest entirely with the employer, or whether the worker is also breaking a legal duty by acting in this way and by interfering with the provided protection.
Question: Which statement best describes the employee’s duties under the Health and Safety at Work etc. Act 1974?
Pick an answer to reveal the explanation.
The correct answer is B. Take reasonable care and cooperate (section 7); do not interfere with or misuse safety provisions (section 8). Under section 7 employees must take reasonable care for their own and others’ safety and cooperate with the employer; under section 8 no one may intentionally or recklessly interfere with or misuse anything provided for safety.
Core Lens: High-Yield Takeaways
- Safety duties are two-way. The employer carries the major duties, but section 7 places a clear duty on every employee to take reasonable care for their own health and safety and that of others affected by their acts or omissions.
- Cooperation is part of section 7. Employees must also cooperate with the employer so far as is necessary to enable the employer to meet its own legal duties — for example, by following safe systems and attending surveillance.
- Section 8 forbids interference and misuse. No person may intentionally or recklessly interfere with or misuse anything provided in the interests of health, safety or welfare — removing a machine guard is the classic breach.
- Ignoring provided PPE is a section 7 failure. Refusing to wear a provided respirator for a dusty task is a failure to take reasonable care and breaches the employee’s duty under COSHH regulation 8(2) to make full and proper use of control measures.
- The duties apply to all workers. Sections 7 and 8 bind every employee, not only safety representatives, and accepting personal risk does not excuse endangering others or defeating provided controls.
Mental health & stress: sedating medication in a safety-critical role
Scenario: A 45-year-old who drives a heavy goods vehicle for a logistics firm tells you in an occupational health consultation that his GP has recently started him on a regular sedating medication. He reports daytime drowsiness. He is worried about losing his job and asks you not to tell his employer anything, insisting he is “fine to drive”. His next shift is tomorrow and involves long motorway journeys carrying other road users’ safety.
Question: What is the most appropriate course of action?
Pick an answer to reveal the explanation.
The correct answer is C. Advise against driving, seek consent to tell the employer he is unfit for now and, if refused, disclose in the public interest.
Core Lens: High-Yield Takeaways
- Impairment trumps blood levels: a person must not drive or perform safety-critical work if a medicine impairs their ability, regardless of any specified drug-driving limit; reported daytime drowsiness in an HGV driver is a clear warning.
- Advise on function, seek consent: the OH report to the employer conveys that he is temporarily unfit for the safety-critical element and needs restriction or redeployment, without disclosing the diagnosis or drug – ideally with his consent.
- Confidentiality is strong but not absolute: if he refuses consent and a serious risk of harm to others persists, GMC guidance permits disclosure in the public interest as a last resort, after trying to obtain consent.
- It is the driver’s legal responsibility: the duty not to drive while unfit rests on the individual, but in occupational health there is an added duty to help the employer manage the risk.
- Document and act before the shift: with a shift tomorrow carrying others’ safety, advice and escalation cannot wait.
MSK & Ergonomics: participatory ergonomics in redesigning a high-risk task
Scenario: A manufacturer wants to redesign an assembly task that is causing repeated musculoskeletal complaints. Previous top-down changes, imposed by managers without consulting the line, were poorly used and made little difference. An occupational health adviser is asked to suggest an approach more likely to produce workable, well-adopted improvements to this high-musculoskeletal-risk task.
Question: Which approach best reflects participatory ergonomics?
Pick an answer to reveal the explanation.
The correct answer is C. Involve line workers, with managers and ergonomists, in identifying problems and designing solutions.
Core Lens: High-Yield Takeaways
- Participatory ergonomics means involving the people who do the work — those operators hold detailed, practical knowledge of the task and its problems, and engaging them is central to the approach.
- It is collaborative, not top-down — workers, management and ergonomics/OH expertise work together to identify hazards and to design, trial and refine solutions.
- Involvement drives adoption — solutions developed with the workforce are more practical and far more likely to be used and sustained than changes imposed from above.
- It directly addresses the failure described — the previous top-down changes were poorly used precisely because the line was not consulted; participation fixes that.
Occupational Lung Disease: smoking, occupational exposure and combined risk
Scenario: A 47-year-old man who has worked with asbestos insulation in the past, and continues to be exposed to construction dust, attends an occupational health review. He smokes 20 cigarettes a day. He says he is reluctant to stop smoking because, in his words, the asbestos has ‘already done the damage’, so quitting now would make no difference to his lung-cancer risk.
Question: How should you advise him about the combined effect of smoking and his occupational exposure?
Pick an answer to reveal the explanation.
The correct answer is B. Smoking and asbestos interact to give a combined lung-cancer risk far above either alone; stopping smoking substantially reduces it.
Core Lens: High-Yield Takeaways
- Asbestos and smoking interact more than additively for lung cancer — the combined risk is markedly greater than the sum of the two separate risks (a classic example of synergy in occupational epidemiology).
- Stopping smoking still helps — a lot — even after asbestos exposure has occurred, smoking cessation substantially lowers the future lung-cancer risk, so the “damage is done” fatalism is wrong.
- Many occupational lung carcinogens combine with smoking — the same combined-risk message applies to silica, diesel exhaust, radon and others.
- Mesothelioma is driven by asbestos, not smoking — but lung cancer (a different cancer) is where the smoking interaction is so important, which is why cessation is the key modifiable lever.
- Smoking cessation is core OH business — addressing a powerful, modifiable risk multiplier sits squarely within occupational health’s preventive role.
Physical hazards: appointed doctor and the radiation health record
Scenario: A hospital asks you to clarify the medical-surveillance arrangements for its classified radiation workers. One employee is confused about why he sees an “appointed doctor” as well as having a dose badge, and asks what the doctor actually decides and what happens to the records that are kept about him.
Question: Which statement best describes the role of the appointed doctor and the health record for this classified worker?
Pick an answer to reveal the explanation.
The correct answer is A. The appointed doctor certifies fitness for radiation work in a health record kept for at least 30 years.
Core Lens: High-Yield Takeaways
- The appointed doctor is HSE-appointed — under the Ionising Radiations Regulations 2017, classified persons are under medical surveillance by a doctor specifically appointed by HSE for that purpose (or by an HSE employment medical adviser).
- The doctor certifies fitness, not dose — the appointed doctor judges whether the worker is medically fit for the radiation work and records this in a health record, usually reviewed at least annually; dose itself is measured by the approved dosimetry service.
- The health record is retained long-term — the employer must keep the health record of a classified person until the person has or would have reached 75 and in any event for at least 30 years from the last entry, reflecting the long latency of radiation effects.
- Confidentiality is preserved — the employer is told the fitness conclusion and any work restriction, not the underlying clinical detail.
- Two parallel records exist — the health record (fitness entries by the appointed doctor) and the dose record (approved dosimetry service) are distinct and serve different purposes.
Principles of OH: hand dermatitis presenting in primary care
Scenario: You are a GP seeing a 38-year-old cleaner with a three-week history of an itchy, cracked rash on both hands. She works long shifts using cleaning chemicals and wears occlusive gloves for much of the day. She mentions the rash improves over a week off but flares within a couple of days of returning to work. She is otherwise well, has no past skin history, and asks for “something to clear it up”.
Question: What is the most appropriate initial approach?
Pick an answer to reveal the explanation.
The correct answer is B. Manage the skin while exploring work-relatedness, linking the timing pattern to her workplace exposures.
Core Lens: High-Yield Takeaways
- “Is this work-related?” is a core primary-care question — a symptom pattern that improves away from work and recurs on return should prompt an occupational history (see HSE guidance on work-related dermatitis).
- The history here screams occupational — a hand rash that improves away from work and flares on return, in someone with wet work, chemicals and occlusive gloves, is a classic occupational dermatitis pattern.
- Asking about work changes management — treating the skin without addressing the exposure means the rash will keep recurring; identifying the cause is part of the treatment.
- It is not an either/or — you can manage the skin and explore the occupational cause in the same consultation; neither blanket sick-listing nor dismissing work as irrelevant is right.
- Good work generally supports health — the aim is to keep her working safely where possible, with the cause addressed, not to default to time off.
Sickness absence: appropriate keeping-in-touch during long-term absence
Scenario: A team leader has been off for three months with a serious physical illness and is partway through treatment. Her manager is unsure how to keep in touch: he worries that contacting her at all might be seen as harassment, but also that total silence will make her feel abandoned. He asks OH what approach to keeping in touch during her long-term absence is appropriate.
Question: What is the most appropriate occupational health advice on keeping in touch?
Pick an answer to reveal the explanation.
The correct answer is C. Agree supportive keeping-in-touch contact at a frequency and by a method that suits her, without pressure.
Core Lens: High-Yield Takeaways
- Sensible, agreed contact is good practice: NICE NG146 and ACAS-style absence-management guidance recommend keeping in touch during long-term absence in a way that is supportive and agreed with the employee.
- Contact should be reasonable, not pressuring or intrusive: the aim is to maintain connection and plan support, not to pressure a premature return or surveil the worker.
- Let the employee shape frequency and method: agree how often and by what means (phone, email, occasional meeting) so contact is welcome rather than oppressive.
- Silence and harassment are both failures: no contact risks isolation and a harder return; excessive or coercive contact risks distress and complaints – aim for the supportive middle.
