[Pharmacological intervention in the medication review of institutionalised elderly patients under polypharmacy].

OBJECTIVE

To describe the Drug-Related Problems (DRP) and their resolution after pharmacological review in institutionalised elderly patients under polypharmacy.

DESIGN

Descriptive, retrospective cohort study from January to October of 2022.

LOCATION

Twelve nursing homes at the Community of Madrid.

PARTICIPANTS

295 patients aged 65 or older taking at least 5 chronic medications prescribed prior to the treatment review.

INTERVENTIONS

Medication reviews carried out by the pharmacist and agreed upon in face-to-face meetings between the primary care doctor, the nursing home doctor and the pharmacist.

MAIN MEASUREMENTS

Detected DRP, types and resolution. A age, sex, and number of medications before and after the intervention. Pharmacological subgroups according to anatomical therapeutic chemical classification system (ATC) and active pharmaceutical ingredients involved in the detected DRPs.

RESULTS

1425 DRP were detected, with a mean of 4.85 (SD 3.33) DRPs/patient. The most frequent DRP was reconciliation error (32.52%), followed by pharmaceutical regimen and dosaje. Among the 1425 improvement proposals, 86.73% of them were accepted.Significant statistically differences were observed between the number of medications per patient prior to the pharmacotherapy review (12.29) and after it (10.20), obtaining an average difference of 2.09 (95%CI: 1.98-2.21; P<.001).

CONCLUSIONS

It is found that the intervention of multidisciplinary team in which the pharmacist performs a revision of the medication decreased the number of prescribed medications. Therefore, it reduces polymedication and its associated risks.
