Design: Cost-effectiveness analysis alongside a randomised controlled trial, with Medicare payment valuation and patient time costed at average US wage
Population: Women with breast cancer living in medically underserved areas of the USA
Primary outcome: Incremental cost per quality-adjusted life year gained with virtual pain coping skills training versus attention control
Effect: EQ-5D-5L preference weight higher by 0.066 (P=0.04); incremental 0.04 QALYs (95% CI 0.00-0.08); ICER $12,725 per QALY (5,566-69,343), rising to $20,438 per QALY (9,051-111,403) including patient time. Hospitalisations trended higher in the intervention group

Behavioural pain interventions work in cancer and are almost never available to the patients furthest from a centre. A randomised trial had already shown that a four-session virtual pain coping skills programme improved pain outcomes for women with breast cancer in medically underserved areas against an attention control. This analysis asks what it costs per unit of benefit.

Quality of life on the EQ-5D-5L was higher by an average of 0.066 preference weight across follow-up (P = 0.04), amounting to an incremental 0.04 quality-adjusted life years (95% CI 0.00-0.08). Against a programme cost of $500, that gives an incremental cost-effectiveness ratio of $12,725 per QALY (95% CI 5,566-69,343). Adding the value of patients' own time — $303 — raises it to $20,438 per QALY.

One finding should not be skipped: medical resource use was similar between groups, but hospitalisations trended higher in the intervention arm. The analysis does not explain this, and in a study whose case rests on cost per QALY, a non-significant trend towards more hospital admissions in the treated group is the number that could invert the conclusion if it turned out to be real.

The ICERs are calculated with Medicare payment rates and US wages, so they do not transfer. What does transfer is the structure: four remote sessions, delivered by a therapist, generating a measurable quality-of-life gain in patients who could not otherwise access the service.

The ICER figures are US-costed and do not transfer to Indian settings
The transferable claim is that four remote sessions produced a measurable quality-of-life gain
Note the non-significant trend towards more hospitalisations in the intervention group
The QALY gain interval reaches zero, so the benefit could be nil
Where remote psychological support exists, this supports directing it at pain specifically

Why it matters

It puts a price on a supportive care intervention, which is the form of evidence that decides whether such services are funded at all.

The statistics, in plain English

An incremental gain of 0.04 quality-adjusted life years with a confidence interval running from 0.00 to 0.08 means the benefit could be anything from nothing to twice the point estimate — and when the denominator of a cost-effectiveness ratio can be near zero, the ratio itself becomes unstable, which is why the upper bound of the ICER interval reaches $69,343. An EQ-5D difference of 0.066 is around the commonly cited threshold for a minimally important difference, so it is real but modest.
