Evidence for validity of a national physician and patient-reported, cross-sectional survey in China and UK: the Disease Specific Programme

Abstract

This study provides evidence that the methodology used for the China and UK parts of the Diabetes DSP produces representative samples that are comparable with other independent sources of patient treatment outcomes data, which may ultimately inform public health decision-making. Although this method could be used in other countries, the current validation applies to UK and China. Further research is required for other countries.
