Published: 28 November 2017 - This is a report on outpatient activity in English NHS hospitals and English NHS-commissioned activity in the independent sector. This annual publication covers the financial year ending March 2017. It contains final data and replaces the provisional data that are published each month. The data are taken from the Hospital Episodes Statistics (HES) data warehouse. HES contains records of all admissions, appointments and attendances for patients admitted to NHS hospitals in England. This publication includes analysis of more than 100 million outpatient appointments recorded in HES data during the 12 month period. A number of breakdowns are provided including by patient's age, gender, whether the appointment was attended or not and by provider. Note that this report counts the number of outpatient appointments rather than the number of patients. The purpose of this publication is to inform and support strategic and policy-led processes for the benefit of patient care. This document will also be of interest to researchers, journalists and members of the public interested in NHS hospital activity in England.
