Brief summary
Introduction: Health-related quality of life (HRQoL) is a commonly used health outcome. For many acute conditions (e.g. fractures), retrospective measurement of HRQoL is necessary to establish pre-morbid health status. However, the validity of retrospective measurement of HRQoL following an intervening significant health event has not been established. The aim of this study was to test the validity of retrospective measurement (recall) of HRQoL by using a test-retest design to measure reliability and agreement between prospective and retrospective patient-reported HRQoL before and after an intervening health event (major elective orthopaedic surgery). Method: Participants were recruited from the pre-admission clinic of a metropolitan hospital. Participants were assessed for their HRQoL using the EQ-5D-5L at two time-points; prospectively at two weeks prior to their date of surgery and then retrospectively (recalling their pre-operative health) following elective hip or knee joint replacement surgery. Prospective measurements were compared with retrospective measurements for the five domain scores (nominal data) using intra-class correlation and for the EQ-Index score and the EQ-Visual Analogue Scale (VAS) score (continuous data), using Pearson’s correlation. Agreement was tested in the continuous variables using Lin’s coefficient of concordance (pc) and inspection of Bland-Altman plots.
Interventions
The condition being observed was health related quality of life (HRQOL). Patients undergoing elective hip or knee replacement surgery were prospectively assessed using the EQ-5D-5L two weeks prior to their surgery. HRQOL was assessed again following the patients surgery but prior to discharge from hospital (i.e. within four days post-surgery), retrospective of two weeks prior to their surgery. The prospective and retrospective measurements were assessed for agreement.
