Abstract
Background
Portugal has among the highest rates of dependency among older adults in Europe. Older adults with aging-related comorbidities are prone to the use of potentially inappropriate medication (PIM).
Objective
The aim of this study was to analyze PIM prescriptions in older Portuguese adults, as well as the change rate of PIM prescriptions over time, and assess the geographical variability between the different regions of mainland Portugal.
Methods
Using a national database, PIM prescriptions were analyzed for older adults (aged 65 years and older) between 2019 and 2021 from 2 perspectives: PIM-defined daily dose (DDD) frequency (%) and DDD per 1000 inhabitants per day (DID).
Results
Overall, mainland Portugal presented a PIM DDD frequency of 9.20%, which was relatively higher in Alentejo and Centro and lower in the North. Alprazolam, fluoxetine, and rivaroxaban were PIM with higher DDD frequency values. Over the years, the DID change rates for these three PIM were –3.80%, –14.86%, and +18.54%, respectively, depending on the geographic region. Alprazolam and fluoxetine were mostly prescribed to older women, whereas rivaroxaban was mostly prescribed to older men.
Conclusions
These results emphasize the need to implement initiatives and interventions to decrease PIM prescriptions in older adults.
期刊介绍：
We also encourage the submission of manuscripts presenting preclinical and very preliminary research that may stimulate further investigation of potentially relevant findings, as well as in-depth review articles on specific therapies or disease states, and applied health delivery or pharmacoeconomics.
CTR encourages and supports the submission of manuscripts describing:
• Interventions designed to understand or improve human health, disease treatment or disease prevention;
• Studies that focus on problems that are uncommon in resource-rich countries;
• Research that is "under-published" because of limited access to monetary resources such as English language support and Open Access fees (CTR offers deeply discounted English language editing);
• Republication of articles previously published in non-English journals (eg, evidence-based guidelines) which could be useful if translated into English;
• Preclinical and clinical product development studies that are not pursued for further investigation based upon early phase results.
