Background and Importance Inappropriate prescription is a risk factor for adverse drug reactions and hospitalisations in the elderly. Concerns about its impact in this age group have led to the development of various strategies to address this issue, with a focus on tools for detecting potentially inappropriate medication (PIM), notably the Beers criteria and the EURO-FORTA list.

Aim and Objectives To compare the 2019 Beers criteria with the 2018 EURO-FORTA list and show their applicability on the primary healthcare context.

Material and Methods We conducted a cross-sectional observational study in a population of patients over 65 years old enrolled in a family health unit in Portugal. Classification of all drugs and active diagnoses in the family health unit according to the tools under analysis. Cross-referencing drugs identified as PIMs according to both instruments with the family health unit database, resulting in the identification of PIMs for each patient, considering their conditions.

Results Twenty-nine of the PIMs according to the Beers criteria are not PIMs according to the EURO-FORTA list; 54 of the PIMs according to the EURO-FORTA list are not PIMs according to the Beers criteria; 47 drugs recommended by the EURO-FORTA list are PIMs according to the Beers criteria. The study included 2,775 patients, 59.70% of whom were on polypharmacy. The prevalence of PIMs was 13.41% according to the Beers criteria and 35.78% according to the EURO-FORTA list, with a higher number of PIMs in women in both instruments. The most frequently prescribed PIMs were benzodiazepines for both tools, followed by antipsychotics and antidepressants.

Conclusion and Relevance The levels of polypharmacy and prescription of PIMs in the presence of certain diseases are considerable in the elderly, in the context of primary healthcare, with both tools being useful in the detection of PIMs. However, there are important differences in the drugs they include, which must be individually analysed from a pharmacotherapeutic point of view. Regarding the integration of these tools into a clinical decision support system, it is concluded that both instruments should be computerised together to take advantage of the benefits of each one and to address the shortcomings that both present.
