What this is
What is a sustained return check?
What is a sustained return check?
A sustained return check is a follow-up assessment carried out some weeks after a worker resumes full duties, confirming whether the role, the hours and the adjustments have actually held rather than simply started. It exists because a return that lasts three weeks and then fails is not the success the closure record recorded.
When is a sustained return check carried out?
At the interval the Return to Work programme sets, counted from the date full duties resumed rather than from the date the case was opened. Doing it too early repeats the closure record's optimism; doing it too late lets a relapse go unlogged until it resurfaces as a new case.
Who carries out a sustained return check?
Occupational health, working from the original case file and, where possible, a direct conversation with the worker. A check completed from records alone can confirm attendance but cannot confirm whether an adjustment has quietly stopped being honoured.
Scope
When is a sustained return check required?
This check sits after the case is administratively closed, and its most common failure is not being run at all because nothing in the closed file demands it.
Use this template when
- A worker has been back on full duties for the number of weeks the programme sets as its check interval
- The original case closure recorded 'Returned to full duties' and that claim needs testing, not just filing
- A prior sustained return check flagged a partial or failed sustain and a further check is due
- The absence trend review needs individual sustainment outcomes to detect a pattern across cases
- A linked record needs this one to exist: links case closure, absence trend review
Do not use it for
- Work Restriction Record, which records what a worker can and cannot do while recovering, for use during the case, not after it.
- Modified Duty Plan, which sets out temporary duties during recovery and is closed out once full duties resume.
- Return to Work Interview, which records the conversation on the day of return, covering fitness and adjustments at that moment rather than weeks later.
- Case Closure Record, which ends the file on the date the outcome is decided and cannot itself confirm whether that outcome held.
- Absence Trend Review, which aggregates outcomes across many cases and depends on this record's output rather than replacing it.
Compliance mapping
Which ISO 45001 cl.9.1 requirements does this satisfy?
ISO 45001 does not name a sustained return check by that title, but its requirement to monitor the effectiveness of measures taken is exactly what this record exists to satisfy: a control, in this case a return to work, is only demonstrated effective by checking it after the fact, not by having been implemented.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 45001 cl.9.1.1 | Monitoring and measurement of the effectiveness of OH&S outcomes and measures taken | Has it held |
| ISO 45001 cl.9.1 | Determination of what needs to be monitored, and at what interval, to evaluate performance | Header |
| ISO 45001 cl.10.2 | Nonconformity and corrective action where a measure taken, here a return to work, is found not to have held | Outcome |
| ISO 45001 cl.8.1.2 | Sustained application of controls, reflected in whether adjustments remain in place rather than lapsing | Has it held |
| ISO 45001 cl.5.4 | Consultation and participation of workers, applied here to the worker's own account of what helped or hindered | What made the difference |
| ISO 45001 cl.9.3 | Trend data on OH&S outcomes considered as an input to management review | Related records |
| ISO 45001 cl.7.5.3 | Control of documented information, including the sign-off that confirms the check was actually carried out | Outcome |
What it does not cover
- Work Restriction Record, which documents an active restriction during recovery rather than confirming one has or has not held afterward.
- Modified Duty Plan, which is the plan for temporary duties, not the later confirmation of what happened once full duties resumed.
- Return to Work Interview, which is the day-of-return conversation and cannot substitute for a check carried out weeks on.
- Case Closure Record, which ends the file on the decided outcome and is the record this check exists to test.
- The corrective action itself, which belongs in the CAPA or new referral raised from this check, not in the check's own narrative fields.
Global
Sustained Return Check requirements by country
The obligation to monitor whether a return has held is a management-system expectation more than a statutory one, though the return-to-work programme it sits inside usually has statutory roots.
Provincial workers compensation board (WCB) return-to-work programmes
Boards increasingly expect evidence that a return was sustained, not just that it occurred, when reviewing claim outcomes.
A closed claim revisited after a relapse is far easier to defend with a sustained return check on file than with only the original closure record.
HSE guidance on managing sickness absence and return to work
No statutory sustained-return check, but HSE guidance treats an unmonitored return as an incomplete case management process.
Where the case relates to a work-related condition, a relapse after an unmonitored return can itself become a finding under the general duty to manage risk to health.
ISO 45001
Clause 9.1 requires monitoring the effectiveness of measures taken, which a return to work is, under a certified management system.
An auditor asks not just whether a return-to-work process exists but whether outcomes are checked afterward and fed back in, which is this record's function.
How to complete it
How to complete a sustained return check, step by step
The scored fields describe a status. Whether that status is true depends on judgement calls the form prompts for but cannot enforce.
Adjustment Quietly Withdrawn exists because supervisors change and informal accommodations fade without anyone deciding to remove them. 'Still On Full Duties: Yes' will not surface this; only asking the worker, specifically about the adjustment rather than how things are going generally, will.
A check run too early repeats the closure record's optimism under a different name. Run too late, it lets a relapse pass unlogged until it resurfaces as a fresh case with no link back. The right interval depends on the condition and the role, not a single figure applied uniformly.
Still In The Role and Still On Full Duties can both read 'Yes' while Adjustments Still Needed reads 'Yes' and Worker Feedback is mixed. That combination describes someone coping, not a held return, and the check should record it as a partial sustain rather than round it up.
Return Sustained answered 'No' or 'Partly' matters twice: for the worker, who may need a new referral, and for the organisation, which needs to know whether a role, task or supervisor pattern keeps producing returns that do not hold. Leaving it in the case file only serves the first.
What auditors find
Most common sustained return check findings
The check, where it exists at all, is usually completed competently. The findings concern whether it was run, and whether an honest 'No' actually went anywhere.
| Finding | Clause | What fixes it |
|---|---|---|
| No sustained return check performed; the case treated as finished at closure. | ISO 45001 cl.9.1 | Make scheduling this check a required output of the Case Closure Record, not a discretionary follow-up. |
| Adjustment Quietly Withdrawn marked Yes with no action raised in response. | ISO 45001 cl.10.2 | Route a Yes answer here directly to an action with an owner, rather than a narrative flag. |
| Return Sustained marked Yes despite recorded absence or a recurred condition. | ISO 45001 cl.9.1.1 | Define what level of Days Absent Since Return or Same Condition Recurred forces Partly or No. |
| Case Reopened marked Yes with no New Referral ID recorded. | ISO 45001 cl.8.1.2 | Require the referral reference before a reopened case can be filed as complete. |
| Check completed from the case file alone, with no worker view recorded. | ISO 45001 cl.5.4 | Treat a blank Worker View On What Helped as an incomplete check, not an optional field. |
| Outcome not linked to the Absence Trend Review despite the feed flag being checked. | ISO 45001 cl.9.3 | Confirm the Absence Trend Review ID is populated whenever the feed flag is set, or it never reaches the aggregate. |
Case in point
Case in point: the check that never happened
A case closure record marked a worker returned to full duties after a shoulder injury, with a modified lifting limit noted as an ongoing adjustment. The case closed cleanly, no sustained return check was scheduled, and the file moved to the closed register. Nine weeks later the worker re-injured the same shoulder, and a new case opened with no reference to the first.
The investigation found the lifting limit had been dropped after six weeks when a new supervisor, unaware of the adjustment, rostered the worker back onto full lifting duties. Nobody had asked the worker whether the adjustment was still in place, because nobody was scheduled to ask. A check at the programme's usual interval would have caught the withdrawal before the second injury, not after it.

From a document you fill in to a programme that runs itself
The check itself is a short conversation and a short form. What fails is the scheduling of it and what happens to an honest 'No' once it is recorded.
Schedules the sustained return check automatically from the case closure date, rather than leaving it to be remembered.
Takes a check that finds a task or role repeatedly failing to sustain a return into the risk register for that task.

Watches for closed cases with no sustained return check on file past the programme's expected interval, and raises it before a relapse resurfaces as an unlinked new case.
Feeds 'What made the difference' answers into supervisor guidance, so adjustments are less likely to be dropped through simple unawareness.

Sustained Return Check definitions and key terms
- Sustained return
- A return to duties confirmed, after a defined interval, to have held, as distinct from a return that was merely underway on the day the case closed.
- Adjustment
- A workplace accommodation, reduced hours, altered duties, a lifting limit, put in place to support a return and expected to remain until formally reviewed.
- Case reopened
- The outcome recorded when a sustained return check finds the return has failed, triggering a new referral rather than a repeat of the original case.
- Redeployed
- Working in a different role from the one held before the case began, recorded here as a distinct outcome from remaining in the original role.
- ISO 45001 clause 9.1
- The monitoring and measurement clause requiring an organisation to determine what needs checking, and at what interval, to know whether its measures are working.
FAQ
Frequently asked questions about sustained return check
Why check again if the case is already closed?+
Because the closure record states an intended or newly observed outcome, not a proven one. Closing on the day of return and never checking again means the organisation only learns a return failed when it reappears as a new case, with the link to the first one often lost.
What counts as the return not being sustained?+
Significant absence since return, the same condition recurring, an adjustment quietly withdrawn, or the worker no longer in the role. Return Sustained should read 'Partly' where some but not all are present, rather than rounded up to a clean outcome.
Who decides the interval for the check?+
The Return to Work programme sets it, and it should vary with the case rather than being fixed. A lifting adjustment and a graduated hours plan do not fail on the same timeframe, and one default interval will catch the wrong one too late.
Should the worker know a check is coming?+
Yes. A check run purely from attendance records cannot ask about a quietly withdrawn adjustment or gather honest feedback, and both are the fields most likely to catch a problem before it becomes a relapse.
What happens if the check finds the return has not held?+
Case Reopened is marked Yes and a New Referral ID raised, restarting the case chain rather than editing the original closure. The closure record stands as the decision made at the time; the reopened case is the correction.
Does a single failed check mean the return-to-work process is broken?+
Not on its own. One case is a worker who needs a new referral. A pattern across many checks, the same task, supervisor or condition, is what the Absence Trend Review exists to surface, and that is the level at which a process problem becomes visible.
