A Cost-Effectiveness Study on Digital Cognitive Behavioural Therapy for Insomnia and its Impact on the QALYs Metric
Dr. Elizabeth Stokes is a senior researcher in the Health Economics Research Centre at the University of Oxford and a health economist. She assesses the cost effectiveness of new interventions and ways of functioning through economic evaluations. Dr. Christopher Miller, research director at Big Health and a senior researcher in the Department of Clinical Neurosciences at the University of Oxford. They discuss their latest research on digital Cognitive Behavioral Therapy (dCBT) for insomnia with Dr. Kate Porcheret from the ESRS’ Digital & Communications Committee.
Dr. Stokes co-authored a paper with Dr. Miller titled “Quality-adjusted life years for digital cognitive behavioural therapy for insomnia (Sleepio): a secondary analysis” in which they investigated the impact of dCBT for insomnia in the Quality-Adjusted Life Years (QALYs) metric and its value for money.
They explain the concept of quality-adjusted life years and how it is used to measure both length and quality of life in economic valuations. Their study found that the digital sleep-improvement program Sleepio (a fully automated digital CBT or dCBT – digital Cognitive Behavioural Therapy), was associated with statistically significant gains in QALYs over time compared to the control group receiving standard care of sleep hygiene education. The benefits may last longer than the 48 weeks evaluated and while the gain in QALYs may not be huge, it is likely to be cost-effective. The researchers considered these types of evaluations very important and will speak with decision makers about these results. This will potentially help with the uptake of Sleepio (or other similar cost-effective products) in healthcare-based systems, like being part of the NHS reimbursement strategy (the UK National Health Service).
The quality-adjusted life year (QALY) is a measure that evaluates the length and quality of life. Used in economic evaluation, it allows to assess whether a treatment is worth its cost (Stokes et al., 2022). One quality-adjusted life year (QALY) is equal to 1 year of life in perfect health (National Institute for Health and Care Excellence – NICE, 2023).
Sleepio is a digital sleep-improvement program featuring Cognitive Behavioural Therapy (CBT) techniques. Cognitive Behavioral Therapy for insomnia (also known as CBTi), trains people to use techniques that address the mental (or cognitive) factors associated with insomnia, such as the ‘racing mind’, and to overcome the worry and other negative emotions that accompany the experience of being unable to sleep (Sleepio, 2023).
