To evaluate patient’s compliance to treatment (Asthma, COPD and Mixed Asthma/COPD) using the TAI test

Material and Methods

All these patients had spirometry with bronchodilator test, l blood count with eosinophil levels and an asthma compliance test. We evaluated inhalor compliance using the TAI test of 10-12 items. We divided the results  in three groups: good compliance (TIA score =50), intermediate compliance (46-49) and bad compliance (less than 45) .Also we evaluated the non-adherence  as erratic, deliberate and unwitting.


We studied 124 patients, age was 58.4 +15.3, there were 60 men. A total of 67 patients were diagnosed of asthma (age 51.9 +16.7), 39 Asthma/COPD (age 65.3+1.5) and 18 with COPD (age 67.2 +8.2).

The score for using the TAI test was for asthmatics 44.07+81, Mixed 45.56+5.13 and for COPD group 47.56+4.78.Table 1

We found differences in patients with asthma and COPD, ( more compliance in patients with COPD p<0.02) also we found that the type of non-adherence such as erratic and deliberate was greater in the asthma group (p<0.05, p<0.02 respectively and inconsistent in the COPD group (p<0.01). Deliberate non-adherence was greater in mixed group in relation to the copd one (p<0.01, unwitting greater in copd than mixed (p0<001) but not between mixed and asthma taking into consideration compliance and type of  lack of compliance.

Conclusion:We found less adherence to treatment in patients with asthma and mixed asthma/copd in relation to patients with copd. The type of non-adeherence was different in these groups, greater erratic and deliberate lack of compliance in the mixed asthma/copd group and greater unwitting in the copd one.
