Using a mobile application to reduce potentially inappropriate prescribing for older Brazilian adults in primary care: a triple-blind randomised clinical trial.

Backgound: Potentially inappropriate prescribing (PIP) has been evaluated in several countries, and several strategies have been devised for deprescribing drugs in older adults. The aim of this study was to evaluate the efficacy of a mobile application in reducing PIP for older adults in primary care facilities in Brazil.

Methods: This randomised, triple-blind, parallel-group trial was conducted in 22 public primary care facilities in Brazil.

Older people's knowledge of the purpose of drugs prescribed at primary care appointments.

Objective: This study aimed to assess older people's knowledge of the purpose of drugs prescribed at medical appointments in primary care units and the possible factors related to their level of knowledge about their medications.

Methods: This was a cross-sectional study conducted in 22 basic health units in Brazil. Patients aged ≥60 years were included in this study (n=674).

Polypharmacy in older patients at primary care units in Brazil.

Background Despite extensive studies of polypharmacy in older patients, no consensus regarding the definition of this practice exists in the literature. Several studies have defined polypharmacy as problematic when considering only the numbers of medications used by patients. Objective This study aimed to assess the prevalence of polypharmacy prescribing by comparing two different definitions (quantitative and qualitative) and evaluating factors associated with this practice in older patients.
