Inhaler Review in Older Adults with Asthma or COPD: A Cost-Effectiveness Study and a Perspective in Portugal
Abstract
Older patients with asthma or chronic obstructive pulmonary disease are particularly susceptible to exacerbations that may be associated with incorrect use of inhalers. Educational programs with inhaler technique review seem to be effective, but no studies have addressed their cost-effectiveness in older adult patients. The objective was to perform a cost-effectiveness analysis of education programs in older patients and estimate the cost benefit of applying such a program in Portugal. We developed a decision tree analysis from a healthcare perspective, according to intervention costs and the exacerbation rates and costs described in a previous meta-analysis. A sensitivity analysis of worst and best case scenarios was performed to estimate thresholds for intervention affordable limits, as well as cost-saving estimations and incremental cost-effectiveness ratios (ICERs) for a Portuguese scenario. We estimated cost-effectiveness thresholds applicable in all settings and performed a sensitivity analysis of a theoretical intervention model in all patients including an inhaler technique review at an annual appointment with a doctor and a nurse. In the best case scenario, the intervention affordable budget could be up to almost 1800€...Continue Reading

Asthma
This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
