28 Median inhaled corticosteroid use (%) Issues with Current Therapies Reported Compliance vs. Actual Use of Inhaled Corticosteroids1/Milgrom, p 1052, Table 1, L1-395.410080Median inhaled corticosteroid use (%)58.4Slide B.8Although ICS are widely used in the treatment of childhood asthma, compliance may be less than optimal. A prospective study specifically assessed compliance in 24 asthmatic children 8 to 12 years of age who required ICS and beta2 agonists for control and who were thought to be compliant. Although patient diaries reported a compliance rate of 95.4% with ICS (i.e., that 95.4% of prescribed doses were taken), electronic monitoring of MDIs revealed that fewer than 60% of doses were actually taken. Moreover, only 31.8% of prescribed doses were taken at the correct time of day. Overall, 92% of patients exaggerated their corticosteroid use. It was concluded that not only did these children fail to comply with therapy, but they misrepresented their use and did so with the tacit approval of their parents.1601/Milgrom, p 1052, Table 1, L1-3; p 1054, C2, ¶1, L2-12; p 1056,C2, ¶2, L1-54031.820(n=24)ReporteduseActualuseActual use at correct timeReported compliance is not always a reflection of actual useAdapted from Milgrom H et al J Allergy Clin Immunol 1996;98(6, pt 1):1051–1057.Reference1.

Five of eight children who required courses of oral corticosteroid during the study were among the least compliant, including two who were hospitalized.1These findings suggest that inadequate control of asthma may reflect noncompliance, a problem that is widespread and that may not be confined to obviously uncooperative patients.18068.21/Milgrom,p 1056, C2, ¶3, L1-8p 1052, C2, ¶1, L1-6; p 1053,C2, ¶1, L9-10;p 1054, C2, ¶2, L1-4; p 1055,C1, L4-9; p 1056,C2, L8-11p 1056, C2, ¶2, L10-1460Compliance(%)402013.7Children with stable asthma* (n=16)Children requiring oral corticosteroid rescue (n=8)*Did not require oral corticosteroidsAdapted from Milgrom H et al J Allergy Clin Immunol 1996;98(6, pt 1):1051–1057.B.9ReferenceMilgrom H, Bender B, Ackerson L et al.

Patients who smoked or had comorbidities, poor adherence, or poor inhaler technique were not excluded from study participation. In fact, smokers comprised almost 25% of the total population of both ELEVATE trials, with smokers older than 45 years of age accounting for 9% of the population in both trials. Further, bronchodilator reversibility was not required for enrollment, allowing the inclusion of patients with a mix of chronic obstructive pulmonary disease and asthma. Adherence and proper inhaler technique were not inclusion criteria although adherence was evaluated during the trial.11. Price D et al. N Engl J Med. 2011;364:1695–1707.

The results of a study in Thailand show that asthma symptom is still uncontrolled in large number of patients as you can see that 15% of patients were admitted, 20% need ER visit and 24% were absent from work due to asthmatic attack.
