Aerobika* device proves to be a cost-effective treatment option in the management of post-exacerbation COPD patients.

The Aerobika* device (Trudell Medical International) is a cost-effective treatment option in the management of COPD exacerbations, according to a study published October 20th in the International Journal of COPD.[1] This study, which used data from the published literature and national fee schedules to model the cost-effectiveness of the Aerobika* device, shows that it provides both clinical benefit and direct medical cost savings in a post-exacerbation care COPD population.

COPD is a major (and growing) source of morbidity, mortality and healthcare utilization, with hospitalization for acute exacerbations being the biggest cost driver.[2] Once a patient experiences an exacerbation, the risk of further exacerbation is increased two- to four-fold[3], and many patients experience two or three exacerbations every year.[4] As many as one in five patients discharged from hospital following an exacerbation are re-admitted within 30 days.[5]

The economic burden on the healthcare system associated with COPD is significant; in the US alone, the cost of COPD in 2010 was estimated to be US $50 billion; $30 billion in direct healthcare expenditure, with the remainder accounted for by indirect costs such as productivity losses and costs to families.[6] Approximately half of the direct costs could be accounted for by hospital care for COPD exacerbations,[6] which supports the GOLD guideline treatment goals of minimizing the negative impact of exacerbations and preventing recurrences.[2] Healthcare systems in many countries acknowledge the problem, and policies are now being put in place to try to address it; the US Medicare Hospital Readmission Reduction Program penalizes hospitals for excess 30-day, all-cause readmissions after a hospitalization for an acute exacerbation of COPD.[7]

The Aerobika* device is a drug-free, handheld mechanical oscillating positive expiratory pressure (OPEP) device that has been designed to address the structural and functional challenges in the airways of patients with COPD. When the patient exhales through the device, it helps to expand the airways, loosen and expel mucus from the lungs and may also enhance drug deposition. It has been shown to improve lung function, exercise capacity and quality of life in COPD patients,[8] and a recent real-word study showed that the device reduced exacerbation rates in patients during the critical 30-day post-exacerbation period.[9] Using data from the latter study to provide real-world input, the authors of this current analysis showed cost savings ($553 per patient) and improved outcomes (equivalent to 6 fewer exacerbations per 100 patients per year) with the Aerobika* device compared with no OPEP/PEP use, and concluded that the device provides cost-effective treatment for post-exacerbation COPD patients.

The authors also used various scenarios to investigate the likelihood of the benefit continuing over a full year, and predicted further clinical and cost benefits (21 exacerbations per 100 patients per year; cost savings of $1,952 per patient). Author Dominic Coppolo, MBA, RRT, FAARC, Vice President Clinical Strategy and Development noted, "Our model provides evidence of clinical and cost benefits of the Aerobika* device in that critical 30-day period following an exacerbation. Given the high burden of COPD - in particular, costs relating to exacerbations - in the US population, we would expect that even a small benefit would have a significant impact on the healthcare system". He went on to say that, although further studies would be needed to validate the long-term effectiveness, these data also give a good indication that the benefits will be sustained with long-term use.

"With the increasing pressure to improve care and reduce hospital admissions, the previously-published real-world study showing exacerbation reductions in the critical 30-day post exacerbation period gave us useful insights into the benefits of integrating the Aerobika* device into standard clinical practice", noted Dr Jason Suggett (Group Director of Global Science and Technology, TMI). "This new analysis now gives us clear evidence that such clinical benefits would be translated into cost-effectiveness in this post-exacerbation population. Moreover, we just presented new data at CHEST 2017 demonstrating that the proprietary pressure/oscillation engine of the Aerobika* device efficiently generates oscillations throughout a high percentage of each exhaled breath, and with consistently high pressure amplitudes. The Aerobika* device demonstrated efficient and effective performance related to therapeutic effectiveness nearly twice that of other devices tested."[10]

About the Aerobika® device   
The Aerobika* device is a hand-held, robust, easy-to-use, drug-free oscillating positive expiratory pressure (OPEP) device designed to help expel mucus from the lungs, expand airways and enhance drug deposition. When the patient exhales through the device, intermittent resistance creates a unique pressure-oscillation dynamic, which expands the airways, helps expel the mucus to the upper airways where it can be coughed out. The Aerobika* device is designed to function independent of angle of use or flow rate, and allows for a direct aerosol pathway for patients using a nebulizer for medication delivery. The Aerobika* device has been shown to significantly improve forced vital capacity (FVC), 6-min walk distance (6MWD), and St. George's Respiratory Questionnaire (SGRQ) score in COPD patients.[8] The Aerobika* device is available in Canada, Mexico, and select European countries including the UK and Germany through Trudell Medical International and in the US via Monaghan Medical Corporation.

About the study
A one-year Markov model was used to estimate the cost-effectiveness of the Aerobika* device in patients who had experienced an exacerbation in the previous month, or a post-exacerbation care population, with input data from the published literature and national fee schedules. Using a base-case assumption that the benefit of the Aerobika* device would last 30 days, cost-savings ($553 per patient) and improved outcomes (ie, 6 fewer exacerbations per 100 patients per year) were demonstrated when compared with no OPEP/positive expiratory pressure use. Assuming a scenario with effect beyond the conservative 30 day time frame, the Aerobika* device continued to show benefit (21 exacerbations per 100 patients per year; cost savings of $1,952 per patient). One-way sensitivity analyses were conducted for all input variables, increasing or decreasing the effect by 20%, to determine the impact of change on costs and health effects; the results supported the robustness of the base-case conclusions.
