The Cost of Unplanned Respiratory Care

While chronic respiratory diseases often require ongoing management, it is unplanned exacerbations that place the greatest strain on NHS resources. Exacerbations frequently result in emergency department attendances, ambulance call-outs and hospital admissions, making them one of the most resource-intensive aspects of respiratory care. In COPD, exacerbations account for the majority of healthcare costs, with hospital admissions being the largest single contributor to NHS expenditure [2].

Emergency admissions are expensive, with a single hospitalisation for an acute COPD exacerbation estimated to cost between £1,000 and £7,000, depending on severity, with more severe exacerbations often requiring prolonged inpatient care or intensive care support [8]. During periods of high seasonal demand, respiratory admissions contribute significantly to bed occupancy, reducing capacity across the wider health system [1].

The impact extends well beyond the initial admission. Approximately 20% of patients admitted with a COPD exacerbation are readmitted within 30 days, while almost one-third are readmitted within 90 days [9]. Recurrent exacerbations are also associated with accelerated decline in lung function, poorer quality of life, greater risk of future hospitalisation and increased mortality [2]. As a result, each exacerbation increases demand not only on acute services but also on primary care, community respiratory teams and pulmonary rehabilitation services.

The Opportunity for Earlier Intervention

Many respiratory exacerbations develop gradually over several days, with worsening symptoms and measurable physiological changes preceding the need for emergency care. However, these early warning signs often occur between routine clinical appointments and may go unnoticed until the patient's condition has deteriorated sufficiently to require urgent treatment [2].

Continuous remote monitoring offers an opportunity to identify deterioration earlier by providing clinicians with objective, longitudinal data on a patient's respiratory status. Detecting subtle changes over time could enable earlier intervention, helping to prevent exacerbations from progressing to emergency presentations or hospital admissions [2].

Earlier detection could also support more effective risk stratification, allowing clinicians to prioritise patients showing objective evidence of deterioration and target limited NHS resources towards those at greatest risk. As the demand for respiratory services continues to grow, technologies that support proactive, data-driven disease management have the potential to improve patient outcomes while helping the NHS move from reactive care towards prevention [10].

Conclusion

As the prevalence of respiratory disease continues to rise, the NHS faces increasing pressure to deliver high-quality care with limited resources. Supporting earlier detection of deterioration and more proactive management could help reduce avoidable exacerbations, improve patient outcomes and ensure that NHS resources are directed towards those who need them most.
