Patient-reported benefit from oculoplastic surgery

Abstract

Purpose: It is vital that surgeons undertaking oculoplastic procedures are able to show that the surgery they perform is of benefit to their patients. Not only is this fundamental to patient-centred medicine but it is also important in demonstrating cost effectiveness. There are several ways in which benefit can be measured, including clinical scales, functional ability scales, and global quality-of-life scales. The Glasgow benefit inventory (GBI) is an example of a patient-reported, questionnaire-based, post-interventional quality-of-life scale that can be used to compare a range of different treatments for a variety of conditions.

Methods: A cross-sectional study was undertaken using the GBI to score patient benefit from four commonly performed oculoplastic procedures. It was completed for 66 entropion repairs, 50 ptosis repairs, 41 ectropion repairs, and 41 external dacryocystorhinostomies (DCR). The GBI generates a scale from -100 (maximal detriment) through zero (no change) to +100 (maximal benefit).

Results: The total GBI scores of patients undergoing surgery for entropion, ptosis, ectropion, and external DCR were: +25.25 (95% CI 20.00-30.50, P<0.001), +24.89 (95% CI 20.04-29.73, P<0.001), +17.68 (95% CI 9.46-25.91, P<0.001), and +32.25 (95% CI 21.47-43.03, P<0.001), respectively, demonstrating a statistically significant benefit from all procedures.

Conclusion: Patients derived significant quality-of-life benefits from the four most commonly performed oculoplastic procedures.
