Glasgow Benefit Inventory assessment for Transnasal Endoscopic Pituitary Surgery

Purpose:
This study assesses postoperative quality-of-life outcomes in patients undergoing transnasal endoscopic pituitary surgery for pituitary adenoma.
Methods:
This was a retrospective cohort study in a UK tertiary referral centre. 145 patients who had undergone transnasal endoscopic pituitary surgery for pituitary adenoma over a 6-year period at one institution completed the Glasgow Benefit Inventory (GBI) with at least 3 months’ follow up. Patients with prior radiotherapy were excluded.
The GBI is a patient reported outcome measure that assesses post-intervention outcomes in three domains: ‘general’ functioning, ‘social support’, and ‘physical’ functioning. Pre- and post-operative visual loss scores were additionally assessed via a 1 to 5 Likert scale. GBI scores were assessed alongside these visual loss scores, clinical and surgical parameters and demographics.
