↵a Practices in existence in February 2018, except practices with <1000 registered patients.
↵b Working at scale defined as working to serve populations of >30 000 patients, either as single practices or in collaboration with other practices.
↵c Services beyond the core general practice contract, for example, extended access out of hours, and services normally delivered in secondary care.
↵d Large practices, superpartnerships, and multisite organisations, working to deliver core general practice at scale. The core general practice contract requires practices to manage patients who are acutely ill, chronically ill, or terminally ill, during office hours.
↵e IMD 2015 of lower layer super-output area of practice postcode. IMD = Index of Multiple Deprivation. OR = odds ratio.
