Multicenter assessment of the revisit risk for a further drug-related problem in the emergency department in cocaine users (MARRIED-cocaine study).

Introduction And Objectives: Emergency departments (EDs) in Spanish hospitals daily attend a large number of patients for adverse reactions or clinical complications resulting from cocaine use. After discharge, some of these patients revisit the ED for the same reason within a year. The objective of the present study was to quantify the rate of such revisits and identify the factors associated with them.
