Ingredientes Farmacéuticos Activos Potencialmente Inapropiados en Adultos Mayores: Lista IFAsPIAM: Panel de Consenso Argentino.

Objectives: To perform a list agreed by Argentinean experts and adapted to the local context containing potentially inappropriate (PI) medications in old people (OP) usingthe Delphi consensus technique optimized for this subject.

Methods: A preliminary list of potentially inappropriate medications (PIM) was drawn up based on foreign PIM lists and a selective search in the scientific literature. The iterative Delphi process was used to submit the active pharmaceutical ingredients (APIs) of the preliminary PIM list to the panel of Argentinean experts.

[Criteria for defining consensus achievement in Delphi studies that assess potentially inappropriate medications in the elderly].

Background: The statistical analysis of survey responses based on a categorical Likert scale, as those used in the Delphi technique, has been questioned because the methodology used is based on numerical data analysis.

Aim: To develop criteria for defining the consensus achievement in Delphi studies conducted for the assessment of potentially inappropriate medications (PIM) in the elderly.

Methods: It was constructed an index (Yq) which takes into account the agreement by pairs of evaluators, whose calculus equation is based on combinatorial analysis.
