Abstract
Objectives. To assess the adherence to antiasthmatic therapy by the use of questionnaire and objective methods in elderly people, as well as to evaluate the association between cognition, depressive symptoms, functional status, and compliance. Methods. Patients aged 65 to 102 with chronic asthma under therapy were analyzed retrospectively to evaluate adherence using the Modified Morisky (MM) scale and a visual analog scale (VAS). In the second part of the study, a 1-year monitoring of asthma based on electronic diary and assessment of drug usage was performed. The MM scale and VAS as well as the estimation of cognition, depression symptoms, and functional status were carried out at the beginning and at the end of the observations. Results. Among 117 participants at the beginning of the study, only 9% and 21% had high adherence to therapy according to the MM scale and VAS, respectively. After 1 year of monitoring, the compliance assessed by the MM scale increased from 3.08 ± 0.97 to 3.85 ± 1.01 and by the VAS from 44% ± 7.8% to 90% ± 5.9%. Adherence by electronic diary and drug packages was lower than in both MM scale and VAS. Cognition status correlated with the results of MM and VAS tests but did not influence other methods of assessment. There was a statistical correlation between depression symptoms, cognition, and adherence (p >.01) in contrast to functional status. Compliance correlated with asthma control tests and PEFR. Conclusion. Low adherence to antiasthmatic treatment is common in elderly people. Proper monitoring of asthma by the use of diary or assessment of drugs packages with estimation of depression symptoms and cognition status could increase the compliance and asthma control in this group of patients.
