Inter-rater reliability of assessments regarding the quality of drug treatment, and drug-related hospital admissions.

Aims: To investigate inter-rater agreement on the quality of drug treatment, and the relationship between the drug treatment and hospital admission.

Methods: Three specialist physicians and two resident physicians determined, independently and in consensus, the quality of drug treatment from an overall medical perspective, and its association with admission, in 30 randomly selected patients (50% female, median age 72 years) admitted to Sahlgrenska University Hospital, Sweden, in April 2018. The inter-rater agreement was evaluated with Gwet's agreement coefficient (AC ).
