Antiparkinson drugs use and adherence in older adults and associated factors: an integrative review

Abstract

Objectives To identify factors associated with antiparkinson drugs use and adherence in older adults with Parkinson's disease (PD) through an integrative literature review. Method An integrative literature review involving a search for relevant publications in Portuguese, English, and Spanish on the electronic databases LILACS, MEDLINE - via PubMed, Web of Science and Scopus, without restriction regarding date or study design, was carried out during the period August-September 2021. The selection of studies was performed independently by two reviewers and the final validation conducted by a third reviewer. Results After applying the eligibility criteria, 5 of the 460 studies found were included in the review. Results showed moderate adherence rates (range 35.3-66.8%) and the main factors associated with lower adherence to antiparkinson therapy were older age, cognitive deficit, greater motor impairment, multimorbidities, change in therapy regimens, depression, polypharmacy, lower education, non-white ethnicity and male gender. Factors associated with greater adherence were younger age, white ethnicity, no change in therapy regimen, higher level of knowledge about PD, good clinical control, higher educational level, married status, higher income and greater level of awareness. Conclusions Non-adherence to antiparkinsonian therapy was frequent and multifactorial., Understanding this behavior is important to help inform the scientific community and devise public policies and strategic planning in health services for improving the quality of life of the older population.
