This presents the results of a Dutch study which explored how well the howRu and howRwe surveys capture patients’ perceptions. Patients competed the surveys and were then interviewed by a review panel of GPs, who then completed the same surveys. The correlation between the patients and the review panel for howRu was CCC=0.80; for howRwe CCC=0.57. They concluded that howRu is suitable for use clinically at the individual patient level, but howRwe is not [NB howRwe is only used as an aggregate measure].
