Patient-reported benefit from oculoplastic surgery

The Glasgow Benefit Inventory (GBI) is a measure of patient benefit developed especially for otorhinolaryngological (ORL) interventions. Patient benefit is the change in health status resulting from health care intervention. The GBI was developed to be patient-oriented, to be maximally sensitive to ORL interventions, and to provide a common metric to compare benefit across different interventions. The GBI is an 18-item, postintervention questionnaire intended to be given to patients to fill in at home or in the outpatient clinic. In the first part of the paper, five different ORL interventions were retrospectively studied: middle ear surgery to improve hearing, provision of a cochlear implant, middle ear surgery to eradicate ear activity, rhinoplasty, and tonsillectomy. A criterion that was specific to the intervention was selected for each study, so that the patient outcome could be classified as above and below criterion. In all five interventions, the GBI was found to discriminate between above- and below-criterion outcomes. The second part of the paper reports on the results and implications of a factor analysis of patient responses. The factor structure was robust across the study, and so led to the construction of subscales. These subscales yield a profile score that provides information on the different types of patient benefit resulting from ORL interventions. The GBI is sensitive to the different ORL interventions, yet is sufficiently general to enable comparison between each pair of interventions. It provides a profile score, which enables further breakdown of results. As it provides a patient-oriented common metric, it is anticipated that the GBI will assist audit, research, and health policy planning.

To assess the effect of blepharoptosis on patients' visual function and health-related quality of life and to determine what measures are associated with postsurgical change in functional status. Prospective, observational case series. One hundred patients with unilateral or bilateral blepharoptosis. INTERVENTION/MAIN OUTCOME MEASURES: Preoperative and postoperative upper eyelid position (i.e., margin reflex distance [MRD]) and superior visual field (SVF) height, as well as subjective visual function and health-related quality-of-life functional status before and after ptosis surgery. There was a mean 30-point increase in functional index score after ptosis repair (P 0.100). The strongest correlation of postoperative functional index change was with the preoperative functional status (r = -0.79, P < 0.001). Patients' functional status is reduced by blepharoptosis, and surgical repair results in measurable increase in health-related quality of life. Patients' self-reported preoperative functional impairment is most strongly associated with the degree of postsurgical functional improvement.
