Ten-year association between change in speech-in-noise recognition and falls due to balance problems: a longitudinal cohort study.

BACKGROUND: This study examined the relationship between speech-in-noise recognition and incident/recurrent falls due to balance problems ten years later (RQ-1); 10-year change in speech-in-noise recognition and falls (RQ-2a), as well as the role of dizziness in this relationship (RQ-2b). The association between hearing aid use and falls was also examined (RQ-3). METHODS: Data was collected from the Netherlands Longitudinal Study on Hearing between 2006 and December 2022. Participants completed an online survey and digits-in-noise test every five years. For this study, data was divided into two 10-year follow-up time intervals: T0 (baseline) to T2 (10-year follow-up), and T1 (5-years) to T3 (15-years). For all RQs, participants aged ≥ 40 years at baseline, without congenital hearing loss, and non-CI users were eligible (n = 592). Additionally, for RQ-3 participants with a speech reception threshold in noise (SRTn) ≥ -5.5 dB signal-to-noise ratio were included (n = 422). Analyses used survey variables on hearing, dizziness, falls due to balance problems, chronic health conditions, and psychosocial health. Logistic regressions using General Estimating Equations were conducted to assess all RQs. RESULTS: Among individuals with obesity, those with poor baseline SRTn had a higher odds of incident falls ten years later (odds ratio (OR):14.7, 95% confidence interval (CI) [2.12, 103]). A 10-year worsening of SRTn was significantly associated with a higher odds of recurrent (OR: 2.20, 95% CI [1.03, 4.71]) but not incident falls. No interaction was found between dizziness and change in SRTn. Hearing aid use (no use/ < 2 years use vs. ≥ 2 years) was not significantly associated with incident nor recurrent falls. Although there was a significant interaction with sex for this association, the effect of hearing aid use on incident/recurrent falls was not statistically significant among males nor females. CONCLUSIONS: A longitudinal association between the deterioration in SRTn and recurrent falls due to balance problems after 10 years was confirmed in this study. This result stresses the importance of identifying declines in hearing earlier and justifies including hearing ability assessments within fall risk prevention programs. Mixed results of hearing aid use on fall risk warrant further investigation into the temporality of this association and possible differences between men and women.

A comparison of psychosocial health among individuals with different levels of hearing ability during the COVID-19 pandemic.

OBJECTIVE: This study assessed the impact of the COVID-19 pandemic on psychosocial health among individuals with different levels of hearing ability. DESIGN: For this cross-sectional study, adults completed an online digits-in-noise test and survey. Participants were categorised into "good", "insufficient", or "poor" hearing groups. Survey questions included topics on depression, anxiety, distress, somatisation, and loneliness levels. Multiple logistic, linear, and negative binomial regressions examined differences in psychosocial health between hearing groups. Moderation analyses identified vulnerable subgroups. Mediation analyses examined mediating effects of pandemic measures on hearing ability and psychosocial health. STUDY SAMPLE: Eight-hundred and sixty-five adults with or without hearing impairment. RESULTS: Individuals with poor hearing had a higher odds of having elevated anxiety levels and had higher somatisation levels compared to participants with good hearing. Chronic diseases significantly moderated the relationship between poor hearing ability and loneliness. Difficulties with communicating through facemasks, 1.5 m distance, plastic screens, and during video calls significantly mediated the relationships between hearing ability, anxiety and somatisation. CONCLUSIONS: Results highlight the elevated anxiety and somatisation levels experienced among individuals with hearing impairment during the COVID-19 pandemic. More awareness is needed of the negative impact pandemic measures can have on psychosocial health during future health crises.

Cohort profile: Netherlands Longitudinal Study on Hearing (NL-SH).

PURPOSE: The Netherlands Longitudinal Study on Hearing (NL-SH) was set up to examine associations of hearing ability with psychosocial, work and health outcomes in working age adults. PARTICIPANTS: Inclusion started in 2006 and is ongoing. Currently the sample comprises 2800 adults with normal and impaired hearing, aged 18-70 years at inclusion. Five-year follow-up started in 2011, 10-year follow-up in 2016 and 15-year follow-up in 2021. All measurements are web-based. Participants perform a speech-in-noise recognition test to measure hearing ability and fill out questionnaires about their hearing status, hearing aid use, self-reported hearing disability and coping, work status and work-related outcomes (work performance, need for recovery), physical and psychosocial health (depression, anxiety, distress, somatisation, loneliness), healthcare usage, lifestyle (smoking, alcohol), and technology use. FINDINGS TO DATE: The NL-SH has shown the vast implications of reduced hearing ability for the quality of life and health of working-age adults. A selection of results published in 27 papers is presented. Age-related deterioration of hearing ability accelerates after the age of 50 years. Having a history of smoking is associated with a faster decline in hearing ability, but this relationship is not found for other cardiovascular risk factors. Poorer hearing ability is associated with increased distress, somatisation, depression and loneliness. Adults with impaired hearing ability are more likely to be unemployed or unfit for work, and need more time to recuperate from work effort. FUTURE PLANS: Participant data will be linked to a national database to enable research on the association between hearing ability and mortality. Linking to environmental exposure data will facilitate insight in relations between environmental factors, hearing ability and psychosocial outcomes. The unique breadth of the NL-SH data will also allow for further research on other functional problems, for instance, hearing ability and fall risk. TRIAL REGISTRATION NUMBER: NL12015.029.06.

The Effects of Tinnitus and Tinnitus Annoyance on Need for Recovery After Work: Results of the Netherlands Longitudinal Study on Hearing.

OBJECTIVES: The first aim of this study was to examine the relationship between having tinnitus and the need for recovery after work (NFR). The second aim was to investigate whether the level of tinnitus annoyance is associated with NFR. DESIGN: Data from the 5- and 10-year follow-up measurement rounds of the Netherlands Longitudinal Study on Hearing (NL-SH) were used in a cross-sectional analyses. The NL-SH is a web-based prospective cohort study and includes participants aged 18 to 70 years at baseline. For this study, we included only participants who worked at least 12 hours/week and were under the age of 65 years. Participants completed questionnaires on demographic, socioeconomic, psychosocial, hearing-related, and work-related characteristics. In addition, participants answered questions about hearing ability and tinnitus and performed an online digit-triplet speech recognition in noise test to measure the speech reception threshold (SRT) in noise. Participants were asked if (1) they suffer from tinnitus and (2) to rate tinnitus annoyance on a 0-100 numeric rating scale. A linear mixed model was used (1) to estimate the overall (i.e., cross-sectional) association between having tinnitus and NFR and (2) to estimate the overall association between the level of tinnitus annoyance and NFR. The models were checked for effect modification and confounding of factors known to be associated with either tinnitus or NFR and available in the NL-SH. RESULTS: The study sample comprised 770 unique participants in total; 686 and 335 participants at 5- and 10-year follow-up, respectively. Distress, somatization, and self-reported hearing disability appeared to be confounding factors in the analysis of having tinnitus and NFR. After adjusting for these factors, participants with tinnitus had a 2.5% higher NFR (95% confidence interval: -0.9 to 5.9; p = 0.15). In the analysis of tinnitus annoyance and NFR, SRT was an effect modifier. Distress, somatization, depression, and self-reported hearing disability were confounders. After adjustment for effect modification and confounding, tinnitus annoyance was not significantly associated with NFR ( p = 0.79 for tinnitus annoyance). CONCLUSIONS: This study showed that having tinnitus was not associated with a higher NFR. Also, higher levels of tinnitus annoyance were not associated with a higher NFR. NFR was associated with the psychological factors distress, somatization, and depression, which are known to be intricately related to tinnitus. A longitudinal study design is recommended as it can assess the sequence of events, which might help disentangle the association between tinnitus, NFR, and psychological factors.

A comparison of the impact of the COVID-19 pandemic on communication among individuals with and without hearing impairment.

Objective: This study assessed the impact of coronavirus disease-2019 (COVID-19) preventative measures on hearing and communication among individuals with normal and impaired hearing. We also evaluated the use of digital communication tools between these groups.Design: For this cross-sectional study, participants completed an online digits-in-noise test and survey. Survey topics included understanding through masks, behind plastic screens, from a 1.5-m distance, and use of social network sites/apps, direct messaging, and video calling. Logistic regressions assessed the odds of disagreeing versus agreeing with survey statements.Study Sample: A total of 880 adults from the National Longitudinal Study on Hearing completed a survey and hearing test. Based on speech reception threshold scores, participants were categorised into "good" (reference group for all analyses), "insufficient", or "poor" hearing groups.Results: Those with insufficient and poor hearing had more difficulty understanding others through facemasks, plastic screens, and from 1.5 m. Those with poor hearing had a higher odds of video calling more to contact family/friends/acquaintances during the pandemic, but also had more difficulty hearing sufficiently through video calls.Conclusions: This study addresses methodological weaknesses in previous studies. Results strengthen current evidence of the burden COVID-19 measures place on individuals with hearing impairment.

User characteristics associated with use of wrist-worn wearables and physical activity apps by adults with and without impaired speech-in-noise recognition: a cross-sectional analysis.

Objective: To study weekly use of smartwatches, fitness watches and physical activity apps among adults with and without impaired speech-in-noise (SIN) recognition, to identify subgroups of users. Design: Cross-sectional study. Study sample: Adults (aged 28-80 years) with impaired (n = 384) and normal SIN recognition (n = 341) as measured with a web-based digits-in-noise test, from the Netherlands Longitudinal Study on Hearing. Multiple logistic regression analyses were used to study differences and to build an association model. Results: Employed adults in both groups are more likely to use each type of fitness technology (all ORs >3.4, all p-values < 0.004). Specific to fitness watch use, adults living with others use it more (OR 2.5, 95%CI 1.1;5.8, p = 0.033) whereas those abstaining from alcohol (OR 0.3, 95%CI 0.1;0.6) or consuming >2 glasses/week (OR 0.4, 95%CI 0.2;0.81, overall p = 0.006) and hearing aid users (OR 0.5, 95%CI 0.2;0.9, p = 0.024) make less use. Conclusions: Subgroups of adults more and less likely to use fitness technology exist, but do not differ between adults with and without impaired SIN recognition. More research is needed to confirm these results and to develop interventions to increase physical activity levels among adults with hearing loss.

Factors Associated With the Development of Tinnitus and With the Degree of Annoyance Caused by Newly Developed Tinnitus.

OBJECTIVES: Tinnitus is highly prevalent, but only a few risk factors for developing tinnitus are known and little is known about factors associated with the degree of annoyance of new-onset tinnitus. Longitudinal analysis can reveal risk factors associated with the development of tinnitus and might lead to targeted prevention. The aim of this study is twofold. (1) To identify risk factors that are longitudinally associated with the odds of developing tinnitus 5 years later. (2) To identify factors that are cross-sectionally associated with tinnitus annoyance in adults with new-onset tinnitus. METHODS: Baseline, 5-year, and 10-year follow-up data of participants in the Netherlands Longitudinal Study on Hearing (NL-SH) were used. The NL-SH is a web-based prospective cohort study, which started in 2006 and includes both normal hearing and hearing-impaired adults aged 18 to 70 years at baseline. The NL-SH uses an online digit-triplet speech-in-noise test to asses speech recognition ability in noise, and online questionnaires on various aspects of life. At follow-up, participants are asked (1) if they suffer from tinnitus and (2) to rate tinnitus annoyance on a 0 to 100 numeric rating scale. We investigated whether demographic (age, sex, living arrangement, educational level), lifestyle (history of tobacco smoking, alcohol use), health (asthma, severe heart disease, hypertension, history of stroke, osteoarthritis, rheumatoid arthritis, epilepsy, multiple sclerosis, and migraine), hearing (speech recognition ability in noise, hyperacusis, and occupational noise exposure), and psychological variables (distress, somatization, depression, and anxiety) were potential risk factors for new-onset tinnitus, or associated with annoyance caused by new-onset tinnitus. Generalized estimating equations were used to longitudinally analyze the association between potential risk factors and new-onset tinnitus measured 5 years later. A multivariable association model was constructed using a forward selection procedure with p < 0.05 for model entry. Linear regression analysis was used to cross-sectionally analyze the association between potential factors and tinnitus annoyance in new-onset tinnitus. For this purpose, a multivariable association model was constructed using a forward selection procedure with p <0.05 for model entry. RESULTS: In total, 734 participants without tinnitus at baseline were included, from which 137 participants reported to suffer from new-onset tinnitus 5 or 10 years later. Risk factors for new-onset tinnitus were history of smoking (odds ratio 1.5, 95% confidence interval [CI] 1.0 to 2.2, p = 0.027) and higher levels of somatization (odds ratio 2.0, 95% CI 1.2 to 3.3, overall p = 0.024). Factors associated with the degree of tinnitus annoyance were increased levels of anxiety (ß = 11.6, 95% CI 2.3-20.8, overall p = 0.035) and poor speech recognition ability in noise (ß = 13.5, 95% CI, 4.4 to 22.6, overall p = 0.014). CONCLUSIONS: Higher levels of somatization and a history of smoking were found to be risk factors for new-onset tinnitus 5 years later. Anxiety and poor speech recognition ability in noise were associated with higher degrees of tinnitus annoyance in new-onset tinnitus. Somatization deserves to be addressed in future research and clinical practice as it might provide part of a model for the development of chronic tinnitus.

Willingness to participate in a hypothetical orthopaedic diagnostic and invasive surgical trial.

OBJECTIVE: To investigate patient preferences and the determinants of participation willingness in orthopaedic diagnostic or invasive surgical randomized controlled trials. METHODS: This observational study included one hundred patients visiting an orthopaedic clinic. The patients answered if they were willing to participate in a hypothetical invasive and diagnostic trial among patients with a distal radius fracture. RESULTS: We found no difference in participation willingness in either the invasive surgical (66/100) or the diagnostic trial (68/100, p = 0.76). Willingness to participate was not associated with age, gender, country of origin, level of education, marital status, or distance of home from the hospital with the confidence interval for all odds ratios including the value 1. Patients who expressed willingness to participate do so because they wanted to contribute to science; patients who declined to participate wanted to speak with a doctor and to be better informed. CONCLUSION: This study showed a high rate of willingness to participate in orthopaedic surgical invasive trials and in diagnostic trials. Nevertheless, to ensure participation, it is recommended to put emphasis on the contribution to science and to give adequate information about the trial including the opportunity to talk to a doctor.

The Longitudinal Relationship Between Speech Recognition in Noise, Need for Recovery After Work, Job Demand, and Job Control Over a Period of 5 Years.

OBJECTIVE: Hearing impairment may lead to an increased need to recover from fatigue and distress after a day of work. Also, hearing impairment may negatively affect the balance between workload and control over it (job demand and job control). The uptake of hearing solutions may have a positive effect on these outcomes. We aimed to assess the longitudinal relationship between change in speech recognition in noise and changes in need for recovery after work and job demand and job control, and the influence of hearing solutions on these relationships over a period of 5 years. Research questions (RQs) were as follows: (1) Is a 5-year change in speech recognition in noise associated with a change in need for recovery after work over that same 5-year period?; (2) Is a 5-year change in speech recognition in noise associated with a change in job demand and job control over that same 5-year period?; (3) What is the effect of hearing solution uptake in the 5-year period on the change in these outcomes in that same 5-year period? METHOD: Data of the Netherlands Longitudinal Study on Hearing, collected between 2006 and January 2019, were divided into two 5-year follow-up intervals: T0 (baseline) to T1 (5-year follow-up) and T1 (5-year follow-up) to T2 (10-year follow-up). An online digit-triplet in noise test was used to assess speech recognition in noise. Online questionnaires on demographic, socioeconomic, and work-related characteristics were administered. For RQ1-RQ2, the study sample included adults working ≥12 hours per week, with at least two consecutive measurements (n = 783). For RQ3, employees who had not yet obtained hearing solutions at baseline, but who would be eligible based on a speech reception threshold in noise ≥ -5.5 dB signal-to-noise ratio (SNR), were included (n = 147). Longitudinal linear regression analyses using mixed models were performed to assess RQ1-RQ3. RESULTS: After adjusting for baseline values, 5-year change in speech recognition in noise showed a statistically significant association with 5-year change in need for recovery. A worsening of 1 dB SNR in speech recognition in noise in an individual was associated with an increase of 0.72 units in need for recovery (scale range 0 to 100). A 5-year change in speech recognition in noise was not significantly associated with a 5-year change in job demand or job control. The uptake of hearing solutions in the 5-year period did not have a significant effect on change in need for recovery in that same 5-year period. CONCLUSION: The significant longitudinal association between 5-year worsening in speech recognition in noise and increase in need for recovery over the same time period strengthens the evidence for the importance of early detection of a worsening in speech recognition in noise to identify employees with an increase in need for recovery. The absence of an effect of the uptake of a hearing solution on need for recovery indicates that additional alternative interventions may be needed to foster beneficial use of hearing solutions as well as to mitigate the increased need for recovery in case of worsening speech recognition in noise.

Association of beta blocker use and hearing ability in adults: a cross-sectional study.

OBJECTIVES: To investigate the potential association between beta blocker use and hearing ability in adults and to discern whether this effect is dose-dependent. DESIGN: Cross-sectional analyses. Multiple linear regression was performed with hearing ability as the dependent variable and beta blocker use as the independent variable. The independent variable was classified into three dose categories for secondary analysis. Adjustments were made for age, gender, educational level, and tobacco smoking status. STUDY SAMPLE: 1636 adults, 75 of whom reported being on beta blockers, from the internet-based Netherlands Longitudinal Study on Hearing (NL-SH). RESULTS: No significant association was found between beta blocker use and hearing ability in noise. In the adjusted regressions, beta blocker use changed the speech reception threshold in noise (SRT) by -0.04 dB signal-to-noise ratio (SNR) (95%CI [-0.67 to 0.58], p = 0.890). Medium dose beta blocker use changed SRT by -0.42 dB SNR (95%CI [-1.38 to 0.71], p = 0.433), while a high dose changed it by -0.26 dB SNR (95%CI [-1.74 to 1.4], p = 0.767). CONCLUSIONS: No evidence was found for beta blocker-induced changes in hearing ability. Future studies on this topic should favour case-control and cohort study designs, while focussing on a hypertensive population to minimise confounding by indication.

A Comparison of the Use of Smart Devices, Apps, and Social Media Between Adults With and Without Hearing Impairment: Cross-sectional Web-Based Study.

BACKGROUND: eHealth and social media could be of particular benefit to adults with hearing impairment, but it is unknown whether their use of smart devices, apps, and social media is similar to that of the general population. OBJECTIVE: Our aim is to study whether adults with normal hearing and those with impaired hearing differ in their weekly use of smart devices, apps, and social media; reasons for using social media; and benefits from using social media. METHODS: We used data from a Dutch cohort, the National Longitudinal Study on Hearing. Data were collected from September 2016 to April 2020 using a web-based questionnaire and speech-in-noise test. The results from this test were used to categorize normal hearing and hearing impairment. Outcomes were compared using (multiple) logistic regression models. RESULTS: Adults with impaired hearing (n=384) did not differ from normal hearing adults (n=341) in their use of a smartphone or tablet. They were less likely to make use of social media apps on a smartphone, tablet, or smartwatch (age-adjusted odds ratio [OR] 0.67, 95% CI 0.48-0.92; P=.02). Use of social media on all devices and use of other apps did not differ. Adults with hearing impairment were more likely to agree with using social media to stay in touch with family members (OR 1.54, 95% CI 1.16-2.07; P=.003) and friends (age-adjusted OR 1.35, 95% CI 1.01-1.81; P=.046). Furthermore, they were more likely to agree with using social media to perform their work (age-adjusted OR 1.51, 95% CI 1.04-2.18; P=.03). There were no differences in the experienced benefits from social media. CONCLUSIONS: The potential for eHealth is confirmed because adults with hearing impairment are not less likely to use smart devices than their normal hearing peers. Adults with hearing impairment are less likely to use social media apps on a smart device but not less likely to use social media on all types of internet-connected devices. This warrants further research on the types of social media platforms that adults with hearing impairment use and on the type of device on which they prefer to use social media. Given that participants with hearing impairment are more likely than their normal hearing peers to use social media to perform their work, use of social media may be seen as an opportunity to enhance vocational rehabilitation services for persons with hearing impairment.

Interobserver agreement for detecting Hill-Sachs lesions on magnetic resonance imaging.

BACKGROUND: Our aim is to determine the interobserver reliability for surgeons to detect Hill-Sachs lesions on magnetic resonance imaging (MRI), the certainty of judgement, and the effects of surgeon characteristics on agreement. METHODS: Twenty-nine patients with Hill-Sachs lesions or other lesions with a similar appearance on MRIs were presented to 20 surgeons without any patient characteristics. The surgeons answered questions on the presence of Hill-Sachs lesions and the certainty of diagnosis. Interobserver agreement was assessed using the Fleiss' kappa (κ) and percentage of agreement. Agreement between surgeons was compared using a technique similar to the pairwise t-test for means, based on large-sample linear approximation of Fleiss' kappa, with Bonferroni correction. RESULTS: The agreement between surgeons in detecting Hill-Sachs lesions on MRI was fair (69% agreement; κ, 0.304; p<0.001). In 84% of the cases, surgeons were certain or highly certain about the presence of a Hill-Sachs lesion. CONCLUSIONS: Although surgeons reported high levels of certainty for their ability to detect Hill-Sachs lesions, there was only a fair amount of agreement between surgeons in detecting Hill-Sachs lesions on MRI. This indicates that clear criteria for defining Hill-Sachs lesions are lacking, which hampers accurate diagnosis and can compromise treatment.

Uptake of Hearing Aids and Hearing Assistive Technology in a Working Population: Longitudinal Analyses of The Netherlands Longitudinal Study on Hearing.

OBJECTIVE: To identify predictors of the 5-year uptake of hearing aids (HAs) and hearing assistive technology (HAT) in a sample of Dutch employees eligible for HAs and/or HAT. The potential predictors included demographic factors (age, sex, marital status, and living situation), education, hearing factors (ability to recognize speech in noise and self-reported hearing disability), distress, self-efficacy, and work-related factors (job demand, job control, and need for recovery). DESIGN: Five-year follow-up data of the Netherlands Longitudinal Study on Hearing (NL-SH) collected until January 2019 were included. An online digit-triplet in noise test, the National Hearing Test (NHT), was used to assess speech-recognition-in-noise ability. In addition, online questionnaires on demographic, socioeconomic, self-reported hearing disability, health, and work-related characteristics were administered. Adults who worked over 12 hours per week, who had not yet taken up HAs or HAT, but who would be eligible for HAs/HAT based on their NHT score (insufficient or poor hearing ability), were included in the study. The 5-year uptake of HAs/HAT was defined as a dichotomous variable of self-reported HA/HAT use reported 5 years later. Generalized Estimating Equations analyses were performed to analyze the associations between potential predicting factors and the 5-year uptake of HAs/HAT, taking into account the repeated measurements of the predicting factors and the 5-year uptake of HAs/HAT. RESULTS: Data of 218 participants were included. The cumulative incidence of the 5-year uptake of HAs/HAT was 15 to 33%, of which 52 employees took up HAs and 11 employees took up HAT. Married participants had increased odds for 5-year uptake of HAs/HAT compared with unmarried participants (odds ratio [OR] = 2.13, 95% confidence interval [CI] = 1.05 to 4.35). Higher self-reported hearing disability (per one unit, scale range 0 to 74) was associated with increased odds for 5-year uptake of HAs/HAT (OR = 1.05, 95% CI = 1.03 to 1.07). Job demand showed a significant interaction with sex (p = 0.002), and therefore, stratified analyses were performed. In male participants, participants with higher job demand scores (per one unit, scale range 12 to 48) had increased odds for 5-year uptake of HAs/HAT (OR = 1.18, 95% CI = 1.05 to 1.35). No difference was seen in females. CONCLUSION: This study confirms that factors predicting the uptake of HAs/HAT in the general or older populations, including marital status and self-reported hearing disability, also extend to the working population. The identification of job demand as a predictor of the uptake of HAs/HAT (in males only) was a novel finding. It demonstrates the importance of considering work-related factors in aural rehabilitation.

Association between Speech Recognition in Noise and Risk Factors of Cardiovascular Disease.

INTRODUCTION: Risk factors for cardiovascular disease (CVD) are associated with sensorineural hearing loss. CVD risk factors are known to cluster and interact, thereby increasing the cumulative risk for CVD. Previously, using the database of the Netherlands Longitudinal Study on Hearing (NL-SH), an association was found between a history of smoking and an increased decline in speech recognition in noise over 10 years of follow-up. Prospectively limited data are available on the association between CVD risk factors, interactions of these risk factors, and hearing loss. In this study, data from the NL-SH were used to study the association between CVD risk factors and speech recognition in noise longitudinally. METHODS: Baseline, 5-year, and 10-year follow-up data of the NL-SH were included. The NL-SH is a web-based prospective cohort study which started in 2006. Participants were aged 18-70 years at baseline. Speech recognition in noise was determined with an online digit-triplet speech-in-noise test. In addition, participants completed online questionnaires on demographic, lifestyle, and health-related characteristics. The association of the ability to recognize speech in noise with CVD risk factors (i.e., obesity, rheumatoid arthritis [RA], hypertension, diabetes mellitus, and dyslipidemia) was analyzed longitudinally. We also analyzed the interaction between these risk factors (including age, sex, and history of smoking) and speech recognition in noise. RESULTS: None of the CVD risk factors or interactions of 2 CVD risk factors was significantly associated with a decline in SRT over time. Obesity (p = 0.016), RA (p = 0.027), and hypertension (p = 0.044) were associated with overall higher (more unfavorable) SRTs. No overall interactions between CVD risk factors were found. CONCLUSION: Obesity, RA, and hypertension were overall associated with a higher SRT, but no longitudinal associations between these or other CVD factors with SRTs were found. Also, no interactions between 2 CVD risk factors and SRTs were found. Although no longitudinal associations between CVD risk factors and decline in SRTs were found, clinicians should be alert about the concurrent association between CVD risk factors and hearing loss.

Long-term Outcome After Nonoperative Treatment for Rockwood I and II Acromioclavicular Joint Injuries.

BACKGROUND: Rockwood I and II acromioclavicular joint injuries are generally treated nonoperatively. The long-term outcome is considered to be good but has not yet been properly investigated. PURPOSE: To assess the long-term outcome after nonoperative therapy for Rockwood I and II acromioclavicular joint injuries regarding functional and radiologic outcome. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Eligible patients visited the emergency department between January 2003 and December 2015 and were ≥16 years old at the time of presentation. The main study parameters were the Constant score, the Disabilities of the Arm, Shoulder and Hand score, and the Simple Shoulder Test. The Constant score was measured in the injured and contralateral shoulders. Radiologic outcomes in both shoulders included joint displacement, joint space, degenerative changes, osteolysis of the distal clavicle, and ossification of the ligaments. RESULTS: A total of 75 patients were included for follow-up. After a median follow-up of 85 months (interquartile range [IQR], 68.0-100.0), the mean Constant score in the injured shoulder for the total sample was 88.6 (SD, 12.7) as compared with 93.3 (SD, 8.7) in the contralateral shoulder, with a significant difference of 4.7 points between shoulders. The median Disabilities of the Arm, Shoulder and Hand score was 4.2 (IQR, 0.0-10.8), and the median Simple Shoulder Test was 100 (IQR, 91.7-100.0). The median patient satisfaction for the injured shoulder was 83 (IQR, 70.0-95.0). Regarding radiologic outcomes, for the injured shoulder versus the contralateral shoulder, patients had similar rates of degeneration (44% vs 46%) but more frequent osteolysis of the distal clavicle (31% vs 0%), ossification of the ligaments (29% vs 7%), and deformity of the distal clavicle (19% vs 0%). CONCLUSION: Despite the frequent occurrence of radiographic changes, long-term functional outcome after Rockwood I and II acromioclavicular joint injuries is good, with only clinically nonrelevant functional differences between the injured and contralateral shoulders.

The Popeye sign: a doctor's and not a patient's problem.

BACKGROUND: The Popeye sign is a frequently reported finding following long head of the biceps (LHB) surgery and may be more often detected by doctors than by patients. This study investigates agreement between patients and doctors regarding the presence of a Popeye sign following LHB surgery. METHOD: This interobserver study investigates agreement between patients and consulting physicians with regard to assessment of a Popeye sign in patients following LHB surgery. Furthermore, this was compared with assessments by non-consulting physicians (observers) using digital photographs of the operated arm, taken both preoperatively and postoperatively. Data about gender, age, and body mass index (BMI) were collected to investigate their role in doctor's reporting of a Popeye sign. Patient's dissatisfaction with a Popeye sign in the operated arm was evaluated as well. RESULTS: Ninety-seven patients (mean age 61 ± 6.0 years, 62% male) underwent LHB surgery. A Popeye sign was reported by 2 patients (2%) as opposed to 32 cases (40%) by consulting physicians, of which only 1 case was in agreement. Krippendorff's alpha (Kalpha) for agreement between observers for preoperative photographs was 0.074 (95% CI -0.277, 0.382) and 0.495 (95% CI 0.317, 0.659) for postoperative cases. Kalpha between observers and consulting physicians for pre- and postoperative cases were 0.033 (95% CI -970, 0.642) and 0.499 (95% CI 0.265, 0.699), respectively. Phi coefficient analysis showed a moderate, statistically significant correlation between male sex and Popeye sign identification. Rank-biserial calculation revealed negligible correlation between BMI and age with regard to detecting a Popeye sign by both consulting physicians and observers. Dissatisfaction about swelling in the upper arm was reported in 1 case, though in a location that did not correspond to the location of a Popeye sign. CONCLUSION: The Popeye sign is more often identified by doctors than by patients after undergoing LHB surgery. BMI and age are not related to the detection of a Popeye sign, but sex is moderately correlated. Together with the low percentage of dissatisfaction of patients with this swelling, this signifies that a Popeye sign seems to be a doctor's rather than a patient's problem.

Study protocol: Effectiveness of dual-mobility cups compared with uni-polar cups for preventing dislocation after primary total hip arthroplasty in elderly patients - design of a randomized controlled trial nested in the Dutch Arthroplasty Registry.

Background and purpose - Dislocation is the leading reason for early revision surgery after total hip arthroplasty (THA). The dual-mobility (DM) cup was developed to provide more stability and mechanically reduce the risk of dislocation. Despite the increased use of DM cups, high-quality evidence of their (cost-)effectiveness is lacking. The primary objective of this randomized controlled trial (RCT) is to investigate whether there is a difference in the number of hip dislocations following primary THA, using the posterolateral approach, with a DM cup compared with a unipolar (UP) cup in elderly patients 1 year after surgery. Secondary outcomes include the number of revision surgeries, patient-reported outcome measures (PROMs), and cost-effectiveness.Methods and analysis - This is a prospective multicenter nationwide, single-blinded RCT nested in the Dutch Arthroplasty Registry. Patients ≥ 70 years old, undergoing elective primary THA using the posterolateral approach, will be eligible. After written informed consent, 1,100 participants will be randomly allocated to the intervention or control group. The intervention group receives a THA with a DM cup and the control group a THA with a UP cup. PROMs are collected preoperatively, and 3 months, 1 and 2 years postoperatively. Primary outcome is the difference in number of dislocations between the UP and DM cup within 1 year, reported in the registry (revisions), or by the patients (closed or open reduction). Data will be analyzed using multilevel models as appropriate for each outcome (linear/logistic/survival). An economic evaluation will be performed from the healthcare and societal perspective, for dislocation and quality adjusted life years (QALYs).Trial registration - This RCT is registered at www.clinicaltrials.gov with identification number NCT04031820.

Follow-up radiographs in isolated Greater Tuberosity fractures lead to a change in treatment recommendation; an online survey study.

INTRODUCTION: It is common practice to obtain follow-up radiographs of non-operatively treated isolated greater tuberosity (GT) fractures 1 to 2 weeks after trauma. However, the majority of non-operatively treated GT fractures remain stable and do not require reconsideration of the initial treatment decision. Radiological follow-up therefore might be unnecessary. Our primary objective was to study whether radiological folow-up changes the initial treatment recommendation, hypothesizing no change. MATERIALS AND METHODS: Radiographs of 25 patients diagnosed with an isolated GT fracture were selected from our hospital database and presented on a web-based platform. Sixty-eight trauma- and orthopedic surgeons evaluated these radiographs. First the radiographs directly post-trauma and then, in random order, the radiographs 5-14 days post-trauma alongside the first radiographs. Each observer evaluated each set of radiographs once. The observers answered which treatment they would recommend (non-operative/operative), and how certain they were about their advice (absolutely certain, certain, some doubt, very uncertain). Recommendation-consistency and inter-observer agreement are presented as percentages and intra class correlation coefficients (ICC). RESULTS: Overall, 84% (95% CI 82.1-85.8) of treatment recommendations was unchanged after evaluation of the second radiograph. Agreement within each observer ranged from 60 to 98%. The mean proportion of patients about whom the observers were (absolutely) certain of their recommendation increased from 70% at the first evaluation to 83% at the second evaluation (12.8; 95% CI 9.8-15.9). Furthermore, the ICC between the surgeons improved from 0.37 (95% CI 0.26-0.54) for the first evaluation to 0.60 (95% CI 0.47-0.74) for the second. CONCLUSION: In 16% of the patients the treatment recommendation for an isolated GT fracture changed after the evaluation of radiographs 1 to 2 weeks post-trauma. In addition, surgeons were more certain about their recommendation and there was less inter-observer variation. Radiological follow-up of a non-operatively treated isolated GT fracture therefore seems justifiable. LEVEL OF EVIDENCE: III, diagnostic study.

Translation, cross-cultural and construct validity of the Dutch-Flemish PROMIS® upper extremity item bank v2.0.

PURPOSE: To develop a Dutch-Flemish translation of the PROMIS® upper extremity (PROMIS-UE) item bank v2.0, and to investigate its cross-cultural and construct validity as well as its floor and ceiling effects in patients with musculoskeletal UE disorders. METHODS: State of the art translation methodology was used to develop the Dutch-Flemish PROMIS-UE item bank v2.0. The item bank and four legacy instruments were administered to 205 Dutch patients with musculoskeletal UE disorders visiting an orthopedic outpatient clinic. The validity of cross-cultural comparisons between English and Dutch patients was evaluated by studying differential item functioning (DIF) for language (Dutch vs. English) with ordinal logistic regression models and McFadden's pseudo R2-change of ≥ 2% as critical value. Construct validity was assessed by formulating a priori hypotheses and calculating correlations with legacy instruments. Floor/ceiling effects were evaluated by determining the proportion of patients who achieved the lowest/highest possible raw score. RESULTS: Eight items showed DIF for language, but their impact on the test score was negligible. The item bank correlated, as hypothesized, moderately with the Dutch-Flemish PROMIS pain intensity item (Pearson's r = - 0.43) and strongly with the Disabilities of the Arm, Shoulder and Hand questionnaire, Subscale Disability/Symptoms (Spearman's ρ = - 0.87), the Functional Index for Hand Osteoarthritis (ρ = - 0.86), and the Michigan Hand Outcomes Questionnaire, Subscale Activities of Daily Living (ρ = 0.87). No patients achieved the lowest or highest possible raw score. CONCLUSIONS: A Dutch-Flemish PROMIS-UE item bank v2.0 has been developed that showed sufficient cross-cultural and construct validity as well as absence of floor and ceiling effects.

Cost-effectiveness of a transitional pharmaceutical care program for patients discharged from the hospital.

BACKGROUND: To improve continuity of care at hospital admission and discharge and to decrease medication errors pharmaceutical care programs are developed. This study aims to determine the cost-effectiveness of the COACH program in comparison with usual care from a societal perspective. METHODS: A controlled clinical trial was performed at the Internal Medicine department of a general teaching hospital. All admitted patients using at least one prescription drug were included. The COACH program consisted of medication reconciliation, patient counselling at discharge, and communication to healthcare providers in primary care. The primary outcome was the proportion of patients with an unplanned rehospitalisation within three months after discharge. Also, the number of quality-adjusted life-years (QALYs) was assessed. Cost data were collected using cost diaries. Uncertainty surrounding cost differences and incremental cost-effectiveness ratios between the groups was estimated by bootstrapping. RESULTS: In the COACH program, 168 patients were included and in usual care 151 patients. There was no significant difference in the proportion of patients with unplanned rehospitalisations (mean difference 0.17%, 95% CI -8.85;8.51), and in QALYs (mean difference -0.0085, 95% CI -0.0170;0.0001). Total costs for the COACH program were non-significantly lower than usual care (-€1160, 95% CI -3168;847). Cost-effectiveness planes showed that the program was not cost-effective compared with usual care for unplanned rehospitalisations and QALYs gained. CONCLUSION: The COACH program was not cost-effective in comparison with usual care. Future studies should focus on high risk patients and include other outcomes (e.g. adverse drug events) as this may increase the chances of a cost-effective intervention. Dutch trial register NTR1519.
