Typical Treatment

ABSTRACT: In healthy individuals, clearance of secretions from the respiratory tract is accomplished primarily through ciliary action. In young children the number of alveoli within the respiratory tract is also lesser and shorter and organisms may move quickly down the respiratory tract triggering more extensive involvement. Postural drainage and percussion are usually taught to family members so that the therapy may be continued at home when needed in cases of chronic disease. Since this highly labour-intensive activity requires the daily intervention of a trained caregiver, it may lead to poor compliance with the recommended treatment plan. The air-pulse generator rapidly inflates and deflates the vest, compressing and releasing the chest wall up to 20 times per second. The vibratory forces of these devices are thought to lower mucus viscosity. High-frequency airway clearance (HFCWC) assist devices generate either positive or negative trans-respiratory pressure excursions. The typical treatment lasts 20-30 minutes, and consists of short periods of compression at different frequencies, separated by coughing. The use of HFCWO compared to CPT also produced a significant improvement in blood inflammation parameter. Key Words: respiratory tract, High-frequency airway clearance (HFCWC), short periods of compression.

Background: Weakness in the muscles used to breathe and swallow can lead to difficulties with airway clearance for people with neurological disorders including neuromuscular disease and cerebral palsy. This can lead to aspiration and other respiratory problems which are the leading causes of death in patients with complex neurological disorders. The Vest™ system supports airway clearance through the use of High-Frequency Chest Wall Oscillation (HFCWO) to loosen secretions in the chest by reducing their viscosity. Objective: To assess the cost-effectiveness of the Vest™ system versus Manual Chest Wall Physiotherapy (MCWP) for airway clearance in patients with neurological disorders including neuromuscular disease and cerebral palsy. Methods: A decision-analytic Markov model was developed to estimate the cost-effectiveness of HFCWO and MCWP over 5- and 10-year time horizons. Costs were estimated from the perspective of the UK National Health Service and personal social services. The main input parameters in the model were: rates of respiratory infection, respiratory-related hospitalisation, antibiotic use for respiratory infection and cost of the Vest™ system. The input parameters were informed by existing clinical guidelines and literature. Sensitivity analyses were conducted to explore uncertainties around the input parameters. Results: Over 5- and 10-year time horizons, the Vest™ system results in more quality-adjusted life-years and lower costs per patient. The Vest™ system has a high probability of being cost-effective (>98%) at willingness-to-pay thresholds of £20,000 and £30,000. The estimated average cost saving per patient over a 5-year time horizon is £5,660 (SD = £2362). Our results show that the Vest™ system may result in approximately £6 million cost savings per 1,000 patients with complex neurological disorders in 5 years. Per 1,000 patients, 2,442 hospital admissions and 49,868 bed days could be averted with the use of the Vest™ system. Our results were generally robust to the sensitivity analyses performed. Conclusion: The Vest™ system results in fewer respiratory infection episodes and hospitalisations, and thus less National Health Service (NHS) resource use, than current practice. Therefore, it is highly likely to be a cost-saving strategy.
