Is occupational medicine right for you?

I have always worked a portfolio career alongside clinical medicine, including a number of leadership roles in clinical practice and medical education. For more than ten years I have also built things in tech, learning mostly outside formal training rather than through a conventional computer science route. The part of that work I found most rewarding was never the code itself. It was the underlying principle: if something you need does not exist, you can build it.

That shaped what I was looking for in a medical specialty too. I was not looking for a lane that would ask me to set the rest of that aside. I wanted something flexible enough to use the whole of what I could do, medicine and the entrepreneurial, technical side of things, rather than one instead of the other.

Occupational medicine fit that unusually well. The work is structured around sessions rather than a single continuous rota, which left room to build something alongside it. In my case, that became OccMed.Space. I could not find AI supported tools that gave real feedback on DOccMed preparation, so I built them, using the same instinct that had shaped the rest of my career.

This is the guide I would have wanted before I started.

Occupational medicine sits between clinical medicine and the world of work. The question an occupational physician is usually answering isn't only what is wrong with this person. It is closer to: can this person do this job safely, what would need to change for them to do it safely, and what is the likely timescale.

That shows up in a few consistent ways across most roles. Consultations are usually scheduled, thirty minutes to an hour, rather than an open list. There is no routine night or weekend on-call rota, though some sectors such as aviation, offshore, and transport expect occasional out-of-hours availability for incidents. Report writing is a core output, not an add-on. After most consultations you are producing a written opinion for an employer, and being clear and defensible in that report matters as much as the clinical judgement behind it.

The other structural difference is who the physician is actually working for. The employee is the patient. The employer is usually the party commissioning and paying for the assessment. The physician's job is to give independent, evidence based advice, not to argue the employer's case or the employee's case. That is a different professional posture from most of clinical medicine, and it takes some adjustment.

It helps to treat this as two separate decisions rather than one. The first is whether to practise occupational medicine at all. The second is whether to become a specialist on the GMC Specialist Register. You do not have to answer both at once.

You can do meaningful, properly supervised occupational health work without immediately committing to specialist training. The Diploma in Occupational Medicine, DOccMed, is the usual starting credential. It is not equivalent to specialist registration, but it opens up genuine work, including management referrals, health surveillance, and some safety critical assessments, within your competence and with proper supervision.

If you want the GMC Specialist Register, there are two routes. The standard one runs through ST3: two to three years of relevant core or specialty experience, then four years of full time higher specialty training, leading to a Certificate of Completion of Training. Entry to ST3 is competitive. NHS England recruitment figures put the 2025 round at around 119 applications for 7 posts nationally, a ratio in the region of 17 to 1. Numbers move from year to year, so check the current figures on fom.ac.uk rather than planning around this one.

The second route is the Portfolio Pathway, previously called CESR, for doctors who have not been through a formal training programme but can demonstrate that their knowledge, skills, and experience match the specialty curriculum. It tends to suit experienced doctors more than doctors early in their careers, because it depends on already having broad, well supervised exposure to build evidence from.

Neither pathway is inherently better. ST3 gives you the most structured route if you can get a post. The Portfolio Pathway is realistic if you build experience first and put together a case for equivalence later, without needing to compete for one of a small number of national training places straight away.

Doctors who move into occupational medicine and stay tend to mention some combination of the following.

They wanted more predictable hours, particularly after years of rota disruption, without leaving medicine. They found themselves more interested in the relationship between health and function than in diagnosis and treatment on their own. The question of whether someone can work, and what would help them do so, turned out to be more engaging than they expected. They wanted a career that could flex around other commitments, part time or portfolio work, without it feeling like a compromise. And a fair number were drawn to working further upstream, on prevention and workplace risk, rather than only responding after someone becomes unwell.

The same doctors are usually just as clear about what put them off, or what caught them out.

Some doctors miss direct treatment. If most of what you enjoy about medicine is prescribing, performing procedures, or seeing someone improve because of something you did, occupational medicine will feel like a step back from that, because it is advisory rather than therapeutic almost all of the time.

Report writing surprises people, even those who expected it. It is not incidental paperwork. A poorly reasoned or badly worded report is a genuine source of complaints and professional risk, so learning to write clearly and defensibly under time pressure is a real skill you need to build.

The ethical position takes adjustment too. You are not on anyone's side. Employees sometimes want you to back a particular adjustment or outcome. Employers sometimes want a definite return date the evidence does not support. Staying independent in both directions, consistently, is harder than it sounds until you are actually doing it.

And access to formal training is genuinely limited, which means patience and some flexibility about which route you take matter more here than in many other specialties.

Both of the decisions above, whether to practise occupational medicine and whether to pursue specialist registration, are easier to make well after some real exposure rather than from reading alone.

A sensible approach is to find a properly supervised occupational health role, even part time, and spend six to twelve months in it before deciding anything more permanent. Pay attention to whether you enjoy the actual consultations and the report writing, not just the improved hours. Notice whether you miss treatment, and how much. Ask whether the role gives you access to a range of case types, or whether it is mostly repetitive management referrals with little variety.

Supervision quality matters more than almost anything else at this stage. A well supervised role with a broad case mix will tell you far more about whether the specialty suits you than a high volume, poorly supported one. It is also worth remembering that a diploma level role and a consultant role can look quite different day to day, so testing the work at diploma level tells you a great deal, but it will not answer every question about specialist practice.
