The threshold value above which tiotropium becomes most cost effective in this third scenario increases to €1,918 for an additional exacerbation-free month and €15,635 for a QALY, yet is still below acceptable limits reported for the Spanish setting.
An increase in the occurrence of an acute exacerbation, in other words additional exacerbations, caused a significant deterioration in the health status in the Fatigue (odds ratio (OR) = 1.77, p = 0.02) and Mastery (OR = 1.92, p = 0.01) domains of the CRQ, and in the Symptom scores (OR = 2.11, p = 0.01) in the SGRQ.
However, to be able to detect 22 additional exacerbations, 39 exacerbations would have been incorrectly (false positive) identified and possibly contacted.
For the binomial evaluation of rates, we extracted data on the number of patients having had at least one exacerbation in each arm over the course of the trial, regardless of how many additional exacerbations patients may have experienced.
The curves show that, in terms of exacerbation-free months, ipratropium has the highest probability of being cost effective when the threshold value for cost per additional exacerbation-free month is below €1,050.
The threshold value for costs per additional exacerbation-free month of €639 above which tiotropium becomes the optimal choice in Spain is higher than the ceiling ratios above which tiotropium became most cost effective in the Netherlands (€0) and Canada (€10) in the 1-year model [ 17].
Lastly, fatigue not only influences the quality of life but may be an additional factor contributing to the exacerbation of the obese condition.
In 7 patients, CD diagnosis was previously established; six were admitted with clinical symptoms consistent with CD exacerbation, and an additional patient with a recurrent groin abscess without apparent luminal symptoms.
Sputum samples from an additional 70 elderly patients with exacerbation of chronic obstructive pulmonary disease with positive detection for influenza virus (n = 50) or respiratory syncytial virus (n = 20) were tested for HMPV infection.
These data suggest an additional mechanism of seizure and tic exacerbation in FXS related to an intergenerational influence from autoimmunity in the mother.
In case of asthma exacerbations patients pay an additional visit to the general practice or chest physician.
