The Office for National Statistics estimates that waits above 2015–16 levels are linked to up to 60,572 extra years of benefit receipt among treated inpatients.1 Set against what treatment is linked to, that is a small share, and more than half of it comes from five specialties.
The ONS published the analysis on 12 October, commissioned by NHS England. It links hospital records for working-age people in England to benefit records, for planned inpatient treatment between 2015 and 2024.1 Treatment was associated with lower benefit receipt for up to five years, compared with a modelled version of the same people untreated.1
The ONS then asked what would have changed if waits had stayed at the 2015–16 distribution, the last year the 92%-within-18-weeks standard was met. Its answer is 38,972 to 60,572 additional person-years on any benefit over five years, across 29 specialties.1 The specialty rows in its Table 1 sum to 60,570 extra years, against 1.41 million fewer years of benefit receipt linked to treatment itself. That is the 4.3% in the headline, a ratio this desk calculated, not one the ONS publishes.1
In trauma and orthopaedics, treatment is linked to 228,704 fewer person-years on benefits, and shorter waits would have raised that by 7.5%.1 Gastroenterology has the biggest treatment-linked fall of any specialty, 321,094 person-years, but waits add only 0.8%.1 In 14 of the 29 specialties the offset is 5% or more, and it is highest in cardiac surgery and urology, at 7.7% each.1
Noodle News reported on 13 October that 65.2% of England's waiting pathways were within 18 weeks in August, against the 92% standard.
The Department for Work and Pensions' Pathways to Work green paper said long waiting lists "led to people going untreated for longer", reducing earlier help, according to Civil Service World.2 The ONS result fits that direction: longer waits, more years on benefits.1
The Institute for Fiscal Studies found that areas where elective waits rose most did not see meaningfully larger rises in disability or incapacity benefit claims. It put the possible effect for mental health and musculoskeletal conditions at no more than 7% of the national rise, according to Civil Service World.2
The two studies ask different questions, one about treated patients over five years and one about local claim trends, and one reading is that both point to a modest role for waits.
The ONS gives no monetary cost, so the extra years cannot be converted into pounds. People still on waiting lists are excluded, and so is everyone outside ages 30 to 59, oncology and haematology. The inpatient and outpatient results cover different patients and cannot be summed. The 95% confidence intervals are in the ONS dataset, which this piece did not retrieve. We did not retrieve the IFS paper itself, and its funder was the Joseph Rowntree Foundation.2
