Sleep Apnoea Costs UK & US Billions – New Research Calls for Screening

Obstructive sleep apnoea, a condition characterized by repeated interruptions in breathing during sleep, carries a significant economic burden, costing the US and UK economies over £137 billion ($185 billion) annually, according to new research published in the journal Thorax. The study highlights the widespread impact of this often-undiagnosed condition, extending beyond individual health to affect national productivity and healthcare systems.

At its core, obstructive sleep apnoea involves the relaxation of throat muscles during sleep, leading to a narrowing or complete blockage of the airway. This results in pauses in breathing, often accompanied by loud snoring and gasping for air. While many individuals may dismiss these symptoms as harmless, they are indicative of a serious health issue linked to an increased risk of cardiovascular disease, including heart attack and stroke.

The prevalence of obstructive sleep apnoea is substantial. Researchers estimate that approximately 1 billion people globally are affected, including around 8 million in the UK. However, a concerning 85% of cases remain undiagnosed, leaving millions vulnerable to the condition’s long-term health consequences and its broader economic impact.

The recent study, led by researchers at University College London, surveyed over 4,000 adults in the UK and US. Findings revealed that roughly one in five respondents reported experiencing breathing pauses during sleep and excessive daytime sleepiness – key indicators of obstructive sleep apnoea. Researchers then extrapolated these findings to estimate the economic consequences, focusing on lost workdays and diminished performance while at work.

The economic toll is considerable. The analysis estimates that obstructive sleep apnoea costs the US economy $180 billion (£133 billion) and the UK economy £4.2 billion each year. Importantly, the study authors acknowledge that this figure is likely an underestimate, as it does not account for increased medical expenses associated with managing the condition, nor the costs related to traffic accidents and workplace injuries potentially linked to daytime fatigue.

The findings underscore the urgent need for improved screening and earlier intervention. The study authors advocate for workplace screening programs, particularly for professions where alertness is critical, such as transportation. “Given the significant yet often overlooked burden of [obstructive sleep apnoea] and its economic impact, we urge policymakers to allocate resources towards developing an effective screening strategy and implementing targeted public health campaigns and policies,” the authors wrote in their published report.

However, addressing obstructive sleep apnoea is not simply a matter of diagnosis. Treatment adherence remains a significant challenge. Nearly two-thirds of patients discontinue continuous positive airway pressure (CPAP) therapy, the most common and effective treatment, which involves wearing a mask during sleep to maintain open airways. This highlights the need for alternative treatment options and strategies to improve patient compliance.

While CPAP remains the gold standard, emerging therapies offer potential alternatives. These include weight loss medications – particularly relevant given the strong association between obesity and obstructive sleep apnoea – oral appliances designed to reposition the jaw and keep the airway open, and hypoglossal nerve stimulation implants, which stimulate the nerve controlling tongue movement. However, these alternatives are not suitable for all patients, and their long-term efficacy is still under investigation.

Beyond the medical challenges, societal factors can also impede effective management of the condition. Concerns about job security can prevent individuals from seeking diagnosis and treatment. Adrian Jones, national officer at the trade union Unite, emphasized the need for employer education and reassurance. “Professional drivers often hide issues of sleep apnoea out of fear of losing their jobs,” he stated. “Before introducing screening, employers must be fully educated that sleep apnoea can be effectively managed. Workers must have the confidence that they will be supported, not dismissed, if a problem is identified.”

The economic and health consequences of untreated obstructive sleep apnoea are substantial. Increased awareness, coupled with accessible screening programs and a supportive work environment, are crucial steps toward mitigating the burden of this widespread, yet often overlooked, condition. Early identification and consistent treatment, the researchers conclude, could yield significant savings – potentially billions annually – in productivity costs and, more importantly, improve the health and well-being of millions.
