Patients undergoing elective inpatient surgery for four common elective procedures (hip and knee replacement, varicose vein surgery and groin hernia surgery) funded by the English NHS are asked to complete questionnaires before and after their operations to assess improvement in health as perceived by the patients themselves.
Extended analyses of the latest finalised data are published three times a year as 'special topics'. The latest, A Study on Varicose Vein Treatments, Patient Reported Outcome Measures (PROMs) in England, was published on 11 February 2016.
