Data only helps when it is coded consistently. Clinicians record diagnoses, reasons for visit and other key information using the coded terms in the clinical software, which draw on a nationally recognised vocabulary such as DOCLE, ICPC or SNOMED CT, rather than free text alone, so that searches and audits are reliable. The practice then interrogates its data, with clinical audit tools or built-in reports, to find gaps such as diabetic patients overdue for review, unrecorded smoking status or missed screening, and runs improvement activities to close them.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
