Funding for the ethnicity DES was dropped at the beginning of April, but practices are still expected to record ethnicity and first language data on their patient population.
A report in the British Journal of General Practice said that studies into the effect of ethnicity on disease prevalence 'are only possible where high rates of ethnicity recording in general practice exist'.
An accompanying editorial called for collection of this data to be 'accelerated by including additional indices of ethnicity recording and measures of social deprivation in the QOF'.
Existing QOF targets for ethnicity recording have improved data quality, but only apply to new registrations.
The report, which focused on the occurrence of cardiovascular multimorbidity in three east London PCTs, found that the burden of cardiovascular multimorbidity fell disproportionately on patients from minority ethnic groups and on south Asians in particular.
