Fitness Certificates and Occupational Health Records: What Gets Signed

Fit and unfit are not enough. The decisions that matter to a factory sit in between — and the wording of that middle ground is what a physician is actually signing.

A fitness certificate looks like a formality until something goes wrong. Then it becomes the document that says what the examining physician knew, what they decided, and what the employer was told to do about it. Structuring that decision properly costs nothing at the time and is worth a great deal afterwards.

The middle ground is the useful part

Most workers are fit. A few are clearly not. The decisions that actually change anything are in between, and collapsing them into a binary destroys the information the factory needs.

  • Fit — no limitation on the work assigned.
  • Fit with advice — cleared for the work, with health guidance for the worker themselves.
  • Fit with restriction — cleared, but not for a specific thing: no night shift for three months, no work at height, a role change.
  • Temporarily unfit — not now, with a stated review point rather than an open ending.
  • Specialist review — a decision the examining physician is not the right person to make alone.
  • Urgent referral — something found today that cannot wait for the file to be typed up.

A restriction is only useful if it is specific and time-bound. Light duties tells a production manager nothing they can act on; no night shift for three months tells them exactly what to change and when to revisit it.

Certificates need numbers

Every certificate should carry a unique number within the issuing centre, and that numbering should be unbroken. Numbering is what makes a certificate checkable: an auditor holding a printed page can ask which record it corresponds to, and a factory can tell whether it holds all of them. Gaps and duplicates are the two things that make a set of certificates look unreliable, regardless of how good the underlying work was.

What belongs in the file

The worker's identity as the factory knows it — employee ID as well as name, because rosters are full of repeated names — the date, the job or department the decision relates to, what was examined, the decision, any restriction or advice, the referral if one was made, and who signed. A decision recorded without the job it relates to is close to meaningless: fitness is always fitness for something.

Flagging out-of-range values

Automated flagging of abnormal values helps the reviewing physician — but only if it is conservative. Reference ranges are often written conditionally, and a system that guesses at which limb of a range applies will eventually shade the wrong cell on a document a doctor is about to sign. Flagging should be treated as advisory, applied only where the range is unambiguous, and said to be advisory on the page itself. A wrong flag is worse than no flag.

Follow-up is part of the record

Referring a worker and never recording what happened next leaves the file weaker than not referring at all: it documents that something was found and stops there. Keeping a follow-up queue — contacted, scheduled, attended, unable to contact — turns a referral into a closed loop, which is both better medicine and better evidence.

SihatSuite records fitness decisions across all six outcomes with restrictions and advice attached, numbers each certificate within the centre, keeps a follow-up queue with priority, and flags out-of-range values conservatively with the advisory footnote printed on the sheet.
