Background: Few have investigated long-term effect of treatment of posttraumatic olfactory dysfunction (OD). Aims/objectives: To explore if sequential treatment with corticosteroids and olfactory training (OT) improved smell in patients with OD after moderate and severe traumatic brain injury (TBI). Material and methods: Twenty-two patients with persistent OD, mean 62 months after trauma, completed an open uncontrolled intervention study of treatment for 10 d with oral corticosteroids and thereafter for 3 months with OT twice daily. Olfaction was assessed by Sniffin’ Sticks. They were tested at four-time points, with the last assessment 12 months after baseline measurements. Results: Mean age at trauma was 45 (SD 14) years. Mean threshold, discrimination and identification (TDI) score at baseline was 14.4 (SD 7.3) and increased to mean 20.8 (SD 7.4) after 1 year (minimum −3.0; maximum 19.5, p value

Background The Norwegian Tonsil Surgery Register (NTSR) was launched in January 2017. The purpose of the register is to present data on tonsil surgery to facilitate improvements in patient care. Data used for evaluating the quality of medical care needs to be of high reliability. This study aims to assess the inter-rater reliability (IRR) of the variables reported to the register by medical professionals. Methods The study population consists of the first 137 tonsil surgery patients who were included in the NTSR at St. Olav’s University Hospital in Trondheim. An experienced rater completed the register’s paper form for all 137 patients based on their electronic medical records, blinded for the data already in the register. To assess the inter-rater reliability between the register and the external rater, we calculated observed agreement, Cohen’s kappa and Gwet’s AC1 coefficients with 95% confidence intervals. Results All tested variables in the NTSR have almost perfect reliability except for the variable for the cold steel technique, which had a substantial to almost perfect reliability. The inter-rater agreement was substantial to almost perfect for every variable, with substantial (kappa/AC1 > 0.61) to almost perfect (kappa/AC1 > 0.81) agreement for all the examined variables. Conclusion This study shows that the reliability of the NTSR is high for all variables registered by the professionals at the hospital immediately after surgery. © The Author(s). 2019 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/)

PURPOSE: Surgical quality registers provide tools to measure and improve the outcome of surgery. International register collaboration creates an opportunity to assess and critically evaluate national practices, and increases the size of available datasets. Even though millions of yearly tonsillectomies and tonsillotomies are performed worldwide, clinical practices are variable and inconsistency of evidence regarding the best clinical practice exists. The need for quality improvement actions is evident. We aimed to systematically investigate the existing tonsil surgery quality registers found in the literature, and to provide a thorough presentation of the planned Nordic Tonsil Surgery Register Collaboration.METHODS: A systematic literature search of MEDLINE and EMBASE databases (from January 1990 to December 2016) was conducted to identify registers, databases, quality improvement programs or comprehensive audit programs addressing tonsil surgery.RESULTS: We identified two active registers and three completed audit programs focusing on tonsil surgery quality registration. Recorded variables were fairly similar, but considerable variation in coverage, number of operations included and length of time period for inclusion was discovered.CONCLUSION: Considering tonsillectomies and tonsillotomies being among the most commonly performed surgical procedures in otorhinolaryngology, it is surprising that only two active registers could be identified. We present a Nordic Tonsil Surgery Register Collaboration-an international tonsil surgery quality register project aiming to provide accurate benchmarks and enhance the quality of tonsil surgery in Denmark, Finland, Norway and Sweden.

'Aim': To evaluate the Hearing Disability and Handicap Scale (HDHS) in an unselected population of adults with hearing impairment. 'Subjects and methods': A total of 342 consecutive adults who consulted the outpatient unit of audiology in the ENT department of a Norwegian university hospital answered HDHS, which intends to assess the negative consequences of hearing loss. The psychometric evaluation included internal structure analyses and made use of principal factors followed by varimax rotation, construct validity by corrected item–total correlation, and internal consistency reliability by Cronbach's alpha coefficient. 'Results': HDHS showed good psychometric properties with three factors, i.e. speech perception (five items), non-speech sound (five items) and participation restriction (10 items). All had good internal consistency reliability. The inventory distinguished between activity limitations and other problems related to social life participation. 'Conclusion:' HDHS was found to be adequate for research and clinical purposes in an unselected adult population with a quite different cultural background and language than the original one.
