In some cases, higher-level functional capacity (instrumental activities of daily living: instrumental ADL) is reduced prior to the decline in ADL functioning in elderly people. The rate of poor self-administration of medication is generally considered to be associated with a decline in ADL and cognitive impairment associated with aging in elderly patients. However, the relationships between patient satisfaction of self-applying transdermal delivery systems of anti inflammatory analgesic drugs (patches) and instrumental ADL in elderly patients are not clear.
In this study, we investigated the relationship between patient satisfaction regarding self-application of patches (satisfaction) and instrumental ADL in elderly patients aged 65 years and over, who independently live at their home (Barthel Index ≥ 60).
We analyzed data from 50 patients (14 males, 36 females; aged 65 - 95 years, with an average age of 77.7 ± 7.3 years) who used a self-administered patch. We conducted a survey on the satisfaction levels with a self-administered questionnaire that used a five-point Likert scale. We used the Barthel Index to measure their ADL, and the Tokyo Metropolitan Institute of Gerontology (TMIG) Index of Competence to measure instrumental ADL. Relationships between overall satisfaction levels and TMIG scores were determined using the Spearman rank correlation, performed using the SPSS Statistics 20.0, at a significance threshold of 5%.
The average Barthel Index score was 93.8 ± 1.0, and the average TMIG score was 11.1 ± 3.0. Additionally, the average overall satisfaction level was 4.3 ± 1.0. Finally, significant positive correlations were observed between overall satisfaction levels and TMIG scores (r = 0.473, P < 0.001).
