Britain’s waiting-list debate normally counts patients and procedures. New ONS analysis suggests another cost can remain long after treatment finally happens: lower earnings.
The cost of an NHS waiting list may not end when the patient finally reaches the operating theatre.
New analysis from the Office for National Statistics has linked longer waits for some musculoskeletal treatments in England with lower employee earnings for years afterwards.
The largest estimated effect was among patients treated for “other joint disorders”.
For those patients, each additional four weeks spent waiting for treatment was associated with an estimated £487 reduction in annual employee earnings in the fourth year after treatment.
And the effect was not confined to one category.
For each additional four weeks waiting, the ONS estimated peak annual earnings reductions of:
- £487 for other joint disorders, in the fourth year after treatment
- £392 for other musculoskeletal conditions, in the third year
- £329 for back, neck and musculoskeletal pain, in the third year
- £301 for osteoarthritis, in the fourth year
The findings turn the NHS waiting-list debate into something more than a question of how long patients must tolerate pain or delayed treatment.
They suggest that, for some working people, the economic consequences of waiting may continue years after the medical procedure itself has taken place.
MORE THAN ONE MILLION PATIENTS STUDIED
The ONS analysis covered 1,019,897 working-age patients who received elective inpatient NHS treatment for musculoskeletal conditions in England between April 2015 and March 2023.
Researchers linked NHS records with information on employment, earnings and benefit receipt and examined patients’ labour-market outcomes for up to five years following treatment.
Median waiting time across the musculoskeletal conditions studied was 69 days.
Patients with osteoarthritis waited longest, with a median of 83 days.
But the ONS was interested in something that ordinary NHS waiting-list statistics do not show.
What happened economically to patients after they were eventually treated?
Its analysis found statistically significant reductions in gross employee earnings associated with longer waiting times across all four condition groups studied.
Those effects could persist for as long as five years after treatment.
LOWER PAY, BUT NOT NECESSARILY LOST JOBS
There is an important qualification.
The ONS did not find statistically significant evidence that longer waits affected whether patients subsequently remained employees.
Nor did it find a statistically significant relationship between longer waits and later receipt of benefits.
That makes the earnings finding particularly interesting.
The apparent economic damage is not primarily showing up in these results as people simply disappearing from employment and moving onto benefits.
Instead, some of it appears in what people earn after treatment.
That distinction matters.
A worker can remain officially employed while suffering an economic loss through reduced hours, lower productivity, missed opportunities, slower progression or changes in the work they are capable of doing.
The ONS analysis establishes the earnings effect, not which of those mechanisms is responsible for it.
A DIFFERENT WAY OF COUNTING THE NHS BACKLOG
Political arguments about NHS waiting lists tend to revolve around headline numbers.
How many people are waiting?
How many weeks have they waited?
How many appointments and operations have been delivered?
Those figures matter.
But they do not capture every cost imposed by delayed treatment.
For a working-age patient, four additional weeks waiting for an operation can also mean another month managing pain or restricted mobility while attempting to remain economically productive.
The new ONS analysis suggests the consequences can remain visible in earnings years later.
That changes the economic calculation surrounding efforts to reduce waiting times.
Faster treatment costs money.
But delayed treatment may also carry costs that never appear on an NHS balance sheet.
They can instead appear in somebody’s payslip.
THE BENEFITS QUESTION IS MORE COMPLICATED
The findings also add an important qualification to another political argument.
Long NHS waiting lists are sometimes blamed for Britain’s rise in health-related benefit claims and economic inactivity.
Previous research by the Institute for Fiscal Studies found little evidence that worsening waits for elective hospital treatment had been a major cause of the increase in working-age health-related benefit claims.
The new ONS analysis does not overturn that conclusion.
It found no statistically significant relationship between longer musculoskeletal treatment waits and subsequent benefit receipt.
But the absence of a clear benefits effect does not mean waiting has no economic consequences.
The ONS results suggest those consequences can instead emerge through lower earnings among people who continue working.
That is a much less visible cost.
THE PRICE OF FOUR MORE WEEKS
There are limits to what the figures can tell us.
The estimates relate specifically to working-age NHS patients receiving elective inpatient treatment for the musculoskeletal conditions studied.
They should not simply be extrapolated across every patient on every NHS waiting list.
And statistical estimates of this kind should not be interpreted as meaning every individual who waits an additional four weeks will personally lose exactly £487.
But the broader finding is difficult to dismiss.
Across a dataset containing more than one million patients, longer waits were associated with significant earnings reductions that persisted after treatment.
Britain has spent years debating the NHS backlog principally as a healthcare crisis.
The ONS has put a price on another part of it.
For some patients, the clock does not stop costing them money when their treatment finally begins.
