NHS 111 Caller Outcomes: Triage vs. Non-Triage Cohorts in Bradford, 2022-2023

Richard Pilbery's study data from figshare compares healthcare outcomes for NHS 111 callers who were triaged versus those who abandoned calls before triage. The dataset includes 19,056 non-triaged and 168,609 triaged index calls from adult patients in Bradford, England, between January 2022 and June 2023. It was last updated in April 2026.
