The use of Patient Reported Outcome Measures (PROMs) is increasingly important in clinical practice. Within the Department of Clinical Neuropsychology at Salford Royal Hospital they are used routinely to collect information on the overall physical, psychological and social adjustment of patients with a traumatic brain injury (TBI). In an attempt to increase PROMs completion rates, we implemented two major changes, reducing the number of PROMs completed and changing the collection method. We critically evaluated the influence that these changes have had on PROMs completion rates and discussed the potential barriers in PROMs completion rates in TBI patients, together with reflections for future improvements of the PROMs used and their administration methods.
