Revised 15-item Glasgow Benefit Inventory with five factors based on analysis of a large population study of medical and surgical otorhinolaryngological interventions

Septal Perforation Repair Quality of Life Outcomes Using the Revised 15-item Glasgow Benefit Inventory

BACKGROUND

The 18-item Glasgow Benefit Inventory (GBI) has been widely used to measure patient general health response to otorhinolaryngologic and facial plastic interventions. The GBI was recently reorganized into 15 questions with 5 sub-scale factors (GBI-5F) to improve its utility. Application of the GBI-5F to septal perforation treatments may improve our understanding of quality of life outcomes.

METHODOLOGY/PRINCIPAL

The GBI was given to patients seen from August 2018 through October 2021 who were at least 6 months postoperative attempted perforation surgical closure using bilateral nasal mucosal flaps with an interposition graft. Original GBI and GBI-5F scores were computed and subgroup analysis performed in this retrospective medical record review.

RESULTS

Of the 98 patients (mean age 45.5 years) who met study criteria, 65 were female. Mean perforation length was 12.9, and height 9.7 mm. The mean postoperative time to GBI completion was 12.7 months. Highest GBI-5F scores were noted in the Quality of Life factor, followed by Self-confidence and Social Involvement. Females reported significantly higher scores than men. Total GBI scores were similar to those recorded for other rhinologic procedures.

CONCLUSIONS

The GBI-5F provides measurable insight into patient quality of life benefit following septal perforation repair.

The impact of waiting time on hearing outcome and patients' satisfaction after cholesteatoma surgery

BACKGROUND

Cholesteatoma is a formation of epithelium mass in the middle ear. Surgery aims to prevent complications while maintain or improve hearing.

AIMS/OBJECTIVES

To determine if waiting time until cholesteatoma surgery affects hearing outcome and patients' satisfaction.

MATERIAL AND METHODS

A retrospective cohort study performed at the only Ear Nose Throat clinic in one county in Sweden. Sixty concomitant surgeries, both first time and revisions, were included.

RESULTS

Of the 60 surgeries, 33 (55%) were performed within a 3-month period. The mean waiting time was 1.4 months. In the remaining 27 cases, the mean waiting time was 8.6 months. Both groups had preoperatively similar air conduction pure tone average (AC PTA4), 47.3 dB and 47.0 dB respectively. The mean AC PTA4 gain was greater in the group with waiting time ≤3 months (8.6 dB) compared to the >3 months group (1.2 dB, p = 0.040). The patients' satisfaction was lower in the latter group, but the difference was not statistically significant.

CONCLUSIONS

This study indicates that longer waiting time to cholesteatoma surgery has a negative impact on postoperative hearing results but not on patients' satisfaction.

SIGNIFICANCE

The outcome of this study suggests that waiting time to surgery can be a factor determining postoperative hearing results.

Measuring benefit from non-surgical interventions in otolaryngology for different conditions, using the revised 5-factor Glasgow Benefit Inventory

OBJECTIVES

The Glasgow Benefit Inventory (GBI) has been extensively used to report the benefit from otolaryngological surgery. Benefit from non-surgical management has not been reported, despite this being the outcome of most otolaryngology and audiology consultations.

DESIGN

GBI responses from 4543 adults from the Scottish ENT Outcome Study were categorised by diagnosis. Benefit scores for different interventions within diagnostic categories for which surgery was not a potential management are reported using the revised 5-factor Glasgow Benefit Inventory (GBI-5F; 15 questions and 5 factors).

SETTING

Adult otolaryngology outpatient clinics in six university hospitals.

PARTICIPANTS

Adults seen with conditions that had no surgical option and given non-surgical management.

RESULTS

Overall, 80% of participants managed in Scottish Ear Nose and Throat Outcome Study (SENTOS) did not have surgery. A total of 1373 (30%) participants with various diagnoses were given reassurance and advice with no active intervention. There was no change in their GBI-5F total or factor scores, suggesting that they did not come to harm from their lack of active intervention. Hearing aids for bilateral sensorineural hearing loss gave greater benefit than reassurance in all factors, though individuals with a conductive impairment reported greater benefit in the Quality of life factor than those with a sensorineural impairment. Hearing aids and maskers produced benefit in the Support factor for patients with tinnitus. Epley's manoeuvre for benign paroxysmal positional vertigo gave benefit in the total score and the Quality of life factor compared with reassurance. Systemic medication for laryngo-pharyngeal reflux and topical medication for otitis externa gave no greater benefit in any factor or the total score compared with reassurance.

CONCLUSION

The GBI-5F and its five factors give useful information for reporting the benefit of non-surgical interventions in adult otolaryngology and audiology clinics.

FiveQ: A new easy-to-use validated clinical instrument for tinnitus severity

OBJECTIVES

Tinnitus is a complex and debilitating phenomenon with potentially significant implications on quality of life. New presentations can be resource and time intensive for clinicians. Validated comprehensive tinnitus questionnaires may lack practical utility in the high-volume clinical setting. Concise, targeted questionnaires may offer an efficient alternative. This study aimed to assess the validity of the FiveQ, a novel five question construct designed to measure tinnitus severity. Convergent validity was assessed through correlating FiveQ against two comprehensive validated questionnaires, the Tinnitus Handicap Questionnaire (THQ) and Tinnitus Handicap Inventory (THI).

DESIGN

Cross-sectional study with prospective recruitment. The 117 voluntarily recruited participants completed the FiveQ, THI and THQ questionnaires. Results were comparatively analysed.

SETTING

Recruitment was via electronic and print media, audiology clinics and public and private otolaryngology outpatient clinics. Surveys were completed electronically.

PARTICIPANTS

Members of the public aged over 18 with subjective tinnitus were invited to participate.

MAIN OUTCOME MEASURED

Analyses for establishing the content validity, construct validity, internal consistency, explorary factor analysis, and responsiveness of FiveQ was performed.

RESULTS

FiveQ demonstrated a high positive correlation with both the THI (r = 0.773, p < .001) and THQ (r = 0.808, p < .001). Internal consistency for FiveQ reached an acceptable threshold (Cronbach's alpha 0.86). Exploratory factor analysis demonstrated that one latent factor underlies the five items of the FiveQ. FiveQ demonstrated better responsiveness than both the THI and THQ after a 6 week interval repeat measurement.

CONCLUSION

FiveQ demonstrated high-positive correlations with existing validated tinnitus questionnaires as well as acceptable internal consistency and factor analysis. The concise construct of FiveQ allows clinicians to efficiently estimate tinnitus severity, target treatment towards dominant symptoms and establish a reliable estimation of treatment response following interventions.

Relationships Between Health-Related Quality of Life and Speech Perception in Bimodal and Bilateral Cochlear Implant Users

Purpose

Previous studies examining the relationship between health-related quality of life (HRQoL) and speech perception ability in cochlear implant (CI) users have yielded variable results, due to a range of factors, such as a variety of different HRQoL questionnaires and CI speech testing materials in addition to CI configuration. In order to decrease inherent variability and better understand the relationship between these measures in CI users, we administered a commonly used clinical CI speech testing battery as well as two popular HRQoL questionnaires in bimodal and bilateral CI users.

Methods

The Glasgow Benefit Inventory (GBI), a modified five-factor version of the GBI (GBI-5F), and the Nijmegen Cochlear Implant Questionnaire (NCIQ) were administered to 25 CI users (17 bimodal and 8 bilateral). Speech perception abilities were measured with the AzBio sentence test in several conditions (e.g., quiet and noise, binaural, and first-ear CI only).

Results

Higher performance scores on the GBI general subscore were related to greater binaural speech perception ability in noise. There were no other relationships between the GBI or NCIQ and speech perception ability under any condition. Scores on many of the GBI-5F factors were substantially skewed and asymmetrical; therefore, correlational analyses could not be applied. Across all participants, binaural speech perception scores were greater than first-ear CI only scores.

Conclusion

The GBI general subscore was related to binaural speech perception, which is considered the everyday listening condition of bimodal and bilateral CI users, in noise; while the more CI-specific NCIQ did not relate to speech perception ability in any listening condition. Future research exploring the relationships between the GBI, GBI-5F, and NCIQ considering bimodal and bilateral CI configurations separately is warranted.
