Nurses' experience of loss, grief, family health and care targeting patients and families in long-term cancer illness: A qualitative study.

PURPOSE: This study aimed to explore the experiences of registered nurses in hematology departments and primary care settings regarding loss, grief, and family health in adult patients and their families during long-term cancer illnesses. METHOD: A qualitative study was conducted taking a phenomenological hermeneutic approach. Data were collected between February and March 2023 through individual, semi-structured interviews with 12 nurses working in hematology departments and primary care settings in Denmark. The interviews were recorded, transcribed, and analyzed using thematic analysis. RESULTS: The analysis resulted in the identification of four main themes with related subthemes: (1) Patients' individual losses leading to grief reactions, (2) Nurses' experience of families grieving the loss of former daily living, (3) Supporting families with family health as an implicit concept, and (4) Overcoming barriers through nurses' care interventions targeting family health. Results showed that nurses encountered various losses and grief reactions affecting both patients and families. Barriers such as experience levels and working conditions affected care quality. Despite challenges, nurses addressed these by utilizing communication, involving families, and directing them to additional healthcare services. CONCLUSION: The study unveiled limited nurse awareness of family health, acknowledging its significance in patient and family care. The findings highlight the importance of improving nurses' comprehension of effectively supporting families as a cohesive unit in the context of long-term cancer illnesses.

Syncope in older adults: challenges, approach and treatment.

Syncope can have devastating consequences, resulting in injuries, accidents or even death. In our ageing society, the subsequent healthcare usage, such as emergency room presentations, surgeries and hospital admissions, forms a significant and growing socioeconomic burden. Causes of syncope in the older adult include orthostatic hypotension, carotid sinus syndrome, vasovagal syncope, structural cardiac abnormalities, cardiac arrhythmias and conduction abnormalities. As stated in the recently published World Falls Guidelines, syncope in older adults often presents as falls, which is either due to amnesia for loss of consciousness, or pre-syncope leading to a fall, especially in those prone to falls with several other risk-factors for falls present. This difference in presentation can hinder the recognition of syncope. In patients with unexplained falls, or in whom the history comprises red flags for potential syncope, special attention to (pre)syncope is therefore warranted. When syncope is mistaken for other causes of a transient loss of consciousness, such as epileptic seizures, or when syncope presents as falls, patients are often referred to multiple specialists, which may in turn lead to excessive and unnecessary diagnostic testing and costs. Specialist services that are able to provide a comprehensive assessment can improve diagnostic yield and minimise diagnostic testing, thus improving patient satisfaction. Comprehensive assessment also leads to reduced length of hospital stay. Increasingly, geriatricians are involved in the assessment of syncope in the older patient, especially given the overlap with falls. Therefore, awareness of causes of syncope, as well as state-of-the-art assessment and treatment, is of great importance.

Applying systems thinking to unravel the mechanisms underlying orthostatic hypotension related fall risk.

Orthostatic hypotension (OH) is an established and common cardiovascular risk factor for falls. An in-depth understanding of the various interacting pathophysiological pathways contributing to OH-related falls is essential to guide improvements in diagnostic and treatment opportunities. We applied systems thinking to multidisciplinary map out causal mechanisms and risk factors. For this, we used group model building (GMB) to develop a causal loop diagram (CLD). The GMB was based on the input of experts from multiple domains related to OH and falls and all proposed mechanisms were supported by scientific literature. Our CLD is a conceptual representation of factors involved in OH-related falls, and their interrelatedness. Network analysis and feedback loops were applied to analyze and interpret the CLD, and quantitatively summarize the function and relative importance of the variables. Our CLD contains 50 variables distributed over three intrinsic domains (cerebral, cardiovascular, and musculoskeletal), and an extrinsic domain (e.g., medications). Between the variables, 181 connections and 65 feedback loops were identified. Decreased cerebral blood flow, low blood pressure, impaired baroreflex activity, and physical inactivity were identified as key factors involved in OH-related falls, based on their high centralities. Our CLD reflects the multifactorial pathophysiology of OH-related falls. It enables us to identify key elements, suggesting their potential for new diagnostic and treatment approaches in fall prevention. The interactive online CLD renders it suitable for both research and educational purposes and this CLD is the first step in the development of a computational model for simulating the effects of risk factors on falls.

Value of a comprehensive geriatric assessment for predicting one-year outcomes in patients undergoing transcatheter aortic valve implantation: results from the CGA-TAVI multicentre registry.

BACKGROUND: In a three-month report from the CGA-TAVI registry, we found the Multidimensional Prognostic Index (MPI) and Short Physical Performance Battery (SPPB) to be of value for predicting short-term outcomes in elderly patients undergoing transcatheter aortic valve implantation (TAVI). In the present analysis, we examined the association of these tools with outcomes up to one year post-TAVI. METHODS: CGA-TAVI is an international, observational registry of geriatric patients undergoing TAVI. Patients were assessed using the MPI and SPPB. Efficacy of baseline values and any postoperative change for predicting outcome were established using logistic regression. Kaplan-Meier analysis was carried out for each comprehensive geriatric assessment tool, with survival stratified by risk category. RESULTS: One year after TAVI, 14.1% of patients deceased, while 17.4% met the combined endpoint of death and/or non-fatal stroke, and 37.7% the combined endpoint of death and/or hospitalisation and/or non-fatal stroke. A high-risk MPI score was associated with an increased risk of all-cause mortality (aOR = 36.13, 95% CI: 2.77-470.78, P = 0.006) and death and/or non-fatal stroke (aOR = 10.10, 95% CI: 1.48-68.75, P = 0.018). No significant associations were found between a high-risk SPPB score and mortality or two main combined endpoints. In contrast to a worsening SPPB, an aggravating MPI score at three months post-TAVI was associated with an increased risk of death and/or non-fatal stoke at one year (aOR = 95.16, 95% CI: 3.41-2657.01). CONCLUSIONS: The MPI showed value for predicting the likelihood of death and a combination of death and/or non-fatal stroke by one year after TAVI in elderly patients.

Comprehensive geriatric assessment in patients undergoing transcatheter aortic valve implantation - results from the CGA-TAVI multicentre registry.

BACKGROUND: In older patients with aortic stenosis (AS) undergoing TAVI, the potential role of prior CGA is not well established. To explore the value of comprehensive geriatric assessment (CGA) for predicting mortality and/or hospitalisation within the first 3 months after transcatheter aortic valve implantation (TAVI). METHODS: An international, multi-centre, prospective registry (CGA-TAVI) was established to gather data on CGA results and medium-term outcomes in geriatric patients undergoing TAVI. Logistic regression was used to evaluate the predictive value of a multidimensional prognostic index (MPI); a short physical performance battery (SPPB); and the Silver Code, which was based on administrative data, for predicting death and/or hospitalisation in the first 3 months after TAVI (primary endpoint). RESULTS: A total of 71 TAVI patients (mean age 85.4 years; mean log EuroSCORE I 22.5%) were enrolled. Device success according to VARC criteria was 100%. After adjustment for selected baseline characteristics, a higher (poorer) MPI score (OR: 3.34; 95% CI: 1.39-8.02; p = 0.0068) and a lower (poorer) SPPB score (OR: 1.15; 95% CI: 1.01-1.54; p = 0.0380) were found to be associated with an increased likelihood of the primary endpoint. The Silver Code did not show any predictive ability in this population. CONCLUSIONS: Several aspects of the CGA have shown promise for being of use to physicians when predicting TAVI outcomes. While the MPI may be useful in clinical practice, the SPPB may be of particular value, being simple and quick to perform. Validation of these findings in a larger sample is warranted. TRIAL REGISTRATION: The trial was registered in ClinicalTrials.gov on November 7, 2013 ( NCT01991444 ).

The Association of Cardiovascular Disorders and Falls: A Systematic Review.

OBJECTIVE: Cardiovascular disorders are recognized as risk factors for falls in older adults. The aim of this systematic review was to identify cardiovascular disorders that are associated with falls, thus providing angles for optimization of fall-preventive care. DESIGN: Systematic review. DATA SOURCES: Medline and Embase. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: studies addressing persons aged 50 years and older that described cardiovascular risk factors for falls. Key search terms for cardiovascular abnormalities included all synonyms for the following groups: structural cardiac abnormalities, cardiac arrhythmia, blood pressure abnormalities, carotid sinus hypersensitivity (CSH), orthostatic hypotension (OH), vasovagal syncope (VVS), postprandial hypotension (PPH), arterial stiffness, heart failure, and cardiovascular disease. Quality of studies was assed using the Newcastle-Ottawa Scale. RESULTS: Eighty-six studies were included. Of studies that used a control group, most consistent associations with falls were observed for low blood pressure (BP) (4/5 studies showing a positive association), heart failure (4/5), and cardiac arrhythmia (4/6). Higher prevalences of CSH (4/6), VVS (2/2), and PPH (3/4) were reported in fallers compared with controls in most studies, but most of these studies failed to show clear association measures. Coronary artery disease (6/10), orthostatic hypotension (9/25), general cardiovascular disease (4/9), and hypertension (7/25) all showed inconsistent associations with falls. Arterial stiffness was identified as an independent predictor for falls in one study, as were several echocardiographic abnormalities. CONCLUSION: Several cardiovascular associations with falls were identified, including low BP, heart failure, and arrhythmia. These results provide several angles for optimizing fall-preventive care, but further work on standard definitions, as well as the exact contribution of individual risk factors on fall incidence is now important to find potential areas for preventive interventions.

Factors associated with recognition and prioritization for falling, and the effect on fall incidence in community dwelling older adults.

BACKGROUND: Recent trials have shown that multifactorial fall interventions vary in effectiveness, possibly due to lack of adherence to the interventions. The aim of this study was to examine what proportion of older adults recognize their falls risk and prioritize for fall-preventive care, and which factors are associated with this prioritization. METHODS: Observational study within the intervention arm of a cluster randomized controlled trial (RCT) on the effect of preventive interventions for geriatric problems in older community-dwellers at risk of functional decline. SETTING:  general practices in the Netherlands. Participants were community dwellers (70+) in whom falling was identified as a condition. A comprehensive geriatric assessment (CGA) was performed by a registered community care nurse. Participants were asked which of the identified conditions they recognized and prioritized for in a preventive care plan, and subsequent interventions were started. Multivariable logistic regression was performed to identify which factors were associated with this prioritization. Fall-incidence was measured during one-year follow-up. RESULTS: The RCT included 6668 participants, 3430 were in the intervention arm. Of those, 1209 were at risk of functional decline, of whom 936 underwent CGA. In 380 participants (41 %), falling was identified as a condition; 62 (16 %) recognized this and 37 (10 %) prioritized for it. Factors associated with prioritization for falls-prevention were: recurrent falls in the past year (OR 2.2 [95 % CI 1.1-4.4]), severe fear-of-falling (OR 2.7 [1.2-6.0]) and use of a walking aid (2.3 [1.1-5.0]). Sixty participants received a preventive intervention for falling; 29 had prioritized for falling. Incidence of falls was higher in the priority group than the non-priority group (67 % vs. 37 % respectively) during first six months of follow-up, but similar between groups after 12 months (40.7 % vs. 44.4 %). CONCLUSIONS: The proportion of community-dwellers at risk of falls that recognizes this risk and prioritizes for preventive care is small. Recurrent falls in the past year, severe fear-of-falling and use of a walking aid were associated with prioritization. Prioritization was associated with a greater fall-risk during first six months, which appeared to level out at one-year follow-up. These results could aid in the identification of community-dwellings likely to benefit from fall-preventive interventions. TRIAL REGISTRATION: NTR2653 , 17 December 2010.

Speech audiometry in Estonia: Estonian words in noise (EWIN) test.

OBJECTIVE: Currently, there is no up-to-date speech perception test available in the Estonian language that may be used to diagnose hearing loss and quantify speech intelligibility. Therefore, based on the example of the Nederlandse Vereniging voor Audiologie (NVA)-lists ( Bosman, 1989 ; Wouters et al, 1994 ) an Estonian words in noise (EWIN) test has been developed. DESIGN: Two experimental steps were carried out: (1) selection and perceptual optimization of the monosyllables, and (2) construction of 14 lists and an evaluation in normal hearing (NH) subjects both in noise and in quiet. STUDY SAMPLE: Thirty-six normal-hearing (NH) native speakers of Estonia (age range from 17 to 46 years). RESULTS: The reference psychometric curve for NH subjects was determined, with the slope and speech reception threshold being well in accordance with the respective values of the NVA lists. The 14 lists in noise yielded equivalent scores with high precision. CONCLUSION: The EWIN test is a reliable and valid speech intelligibility test, and is the first of its kind in the Estonian language.

AF is associated with self-reported syncope and falls in a general population cohort.

BACKGROUND: syncope is an important, but underestimated clinical problem in older persons. It is often overlooked in clinical practice or mistaken for falls. Atrial fibrillation (AF) is the most common cardiac arrhythmia, but little evidence exists regarding the association between AF, falls and syncope in the general population. METHODS: cross-sectional analyses within a population sample of people aged 50+, taken from The Irish Longitudinal Study on Ageing. Ten-minute electrocardiogram recordings (n = 4,885) were analysed to detect AF. Syncope (self-reported faints or blackouts) and falls in the past year, co-morbidities, health measures and medications were gathered through computer-aided personal interviews. Multivariable logistic regression was performed to study associations between AF, falls and syncope. RESULTS: mean age was 62 years (range: 50-91), 54% were female. Prevalence of AF was 3%, increasing to 8% in participants aged 75+. Of participants, 5% (n = 223) reported syncope and 20% (n = 972) reported falls. After adjustment for confounders, AF was significantly associated with faints and blackouts (odds ratio (OR) 2.0 [95% confidence interval (CI) 1.0-3.9]). After stratification by age category, we found that this association was strongest and only significant in participants aged 50-64 years (OR 4.4 [1.5-12.6]). Stratified for age group, AF was significantly associated with falls in participants aged 65-74 years (OR 2.0 [1.0-4.1]). CONCLUSIONS: adults aged 50+ with self-reported syncope and adults aged 65-74 years with falls are twice as likely to have AF at physical examination. These associations are independent of stroke, cardiovascular and psychotropic drugs and other confounders. Further longitudinal studies are needed to explore this association and potential causality further.

Prognostic value of a qualitative brain MRI scoring system after cardiac arrest.

BACKGROUND AND PURPOSE: To develop a qualitative brain magnetic resonance imaging (MRI) scoring system for comatose cardiac arrest patients that can be used in clinical practice. METHODS: Consecutive comatose postcardiac arrest patients were prospectively enrolled. Routine MR brain sequences were scored by two independent blinded experts. Predefined brain regions were qualitatively scored on the fluid-attenuated inversion recovery (FLAIR) and diffusion-weighted imaging (DWI) sequences according to the severity of the abnormality on a scale from 0 to 4. The mean score of the raters was used. Poor outcome was defined as death or vegetative state at 6 months. RESULTS: Sixty-eight patients with 88 brain MRI scans were included. Median time from the arrest to the initial MRI was 77 hours (IQR 58-144 hours). At 100% specificity, the "cortex score" performed best in predicting unfavorable outcome with a sensitivity of 55%-60% (95% CI 41-74) depending on time window selection. When comparing the "cortex score" with historically used predictors for poor outcome, MRI improved the sensitivity for poor outcome over conventional predictors by 27% at 100% specificity. CONCLUSIONS: A qualitative MRI scoring system helps assess hypoxic-ischemic brain injury severity following cardiac arrest and may provide useful prognostic information in comatose cardiac arrest patients.

Decreased left ventricular (LV) function is associated with hip-fractures.

BACKGROUND: Several risk factors for falls and hip-fractures have been recognized, but controversy still exists toward the importance of structural cardiac abnormalities as a potentially modifiable risk factor for recurrent falls. Aim of this study was to determine the association between echocardiographic abnormalities and hip-fractures. METHODS: Design case-control study within consecutive patients undergoing hip-surgery in an academic hospital. CASES: patients with traumatic hip-fractures. CONTROLS: patients undergoing planned hip surgery (non-traumatic). INCLUSION CRITERIA: age≥50 years, presence of pre-operative echocardiogram. EXCLUSION CRITERIA: high energy trauma, pathological and/or previous hip-fracture. OUTCOME: echocardiographic abnormalities (ventricular function, atrial enlargement, valve stenosis and/or regurgitation, pulmonary hypertension (pulmonary artery pressure (PAP) ≥35mmHg)). Multivariate logistic regression was performed to calculate odds ratios (OR) and to correct for confounders. RESULTS: We included 197 patients (141 cases). Mean age was 77 years (SD), 65% female. After adjustment for potential confounders, decreased LV systolic function was associated with hip-fractures (OR 3.2 [95%CI 1.1-9.1]). Increasing severity of LV dysfunction was also associated with hip-fractures (p for trend=0.012). DISCUSSION: In conclusion, patients with traumatic hip-fracture had greater risk of decreased LV function than patients who underwent planned hip-surgery. Possibly, decreased LV function is an underestimated risk factor for injurious falls.

Self-reported cardiovascular conditions are associated with falls and syncope in community-dwelling older adults.

BACKGROUND: with increasing age, causes of syncope are more often of cardiac origin. Syncope in older persons is often mistaken for falls. Data regarding the association between specific cardiovascular conditions, falls and syncope are limited. METHODS: cross-sectional analyses within a population sample aged 50+ (n = 8,173). Syncope and falls in the past year, cardiovascular conditions and co-variates were gathered through personal interviews. Associations between cardiovascular conditions and (recurrent) falls and syncope were studied through multivariable logistic regression. RESULTS: mean age was 64 years (range: 51-105); 54% was female. Four per cent reported syncope, 19% falls and 23% cardiovascular morbidity. Abnormal heart rhythm was associated with falls (odds ratio (OR) 1.3 [95% confidence interval (CI) 1.0-1.5]), syncope (OR 1.6 [1.2-2.3]) and recurrent syncope (OR 2.2 [1.3-3.6]). Heart murmur was associated with falls (OR 1.4 [1.1-1.8]), recurrent falls (OR 1.5 [1.0-2.0]) and syncope (OR 1.9 [1.3-2.7]). Angina was associated with recurrent falls (OR 1.4 [1.0-1.9]), syncope (OR 1.8 [1.2-2.6]) and recurrent syncope (OR 2.7 [1.6-4.6]). Heart failure was associated with recurrent falls (OR 1.9 [1.0-3.4]) and myocardial infarction with syncope (OR 1.5 [1.0-2.3]). CONCLUSION: self-reported cardiovascular conditions are associated with falls and syncope in a general population cohort. This warrants additional cardiovascular evaluation in older patients with unexplained falls and syncope.

Atrial fibrillation is associated with impaired mobility in community-dwelling older adults.

OBJECTIVES: To examine the independent associations between atrial fibrillation (AF) and objectively measured mobility in a nationally representative cohort. DESIGN: Wave 1 of The Irish Longitudinal Study on Ageing (TILDA), a population-based study assessing health, economic, and social aspects of ageing. SETTING: Community-dwelling adults completed a home-based interview and a center-based health assessment. PARTICIPANTS: Participants aged 50 years or older, with Mini-Mental State Examination score of 24 or higher, and who completed at least 1 mobility test (n = 4525). MEASUREMENTS: Mobility was assessed with the Timed Up-and-Go (TUG) test and usual and dual task gait speed obtained using a 4.88-m GAITRite® mat. AF was diagnosed using a 10-minute surface electrocardiogram recording. Linear regression analyses were performed to compare mobility in participants with and without AF, adjusting for confounders. RESULTS: In this sample (mean age 62.3 years; range 51-89), overall prevalence of AF was 3.1%, increasing to 6.7% in the over 70s (11.8% men; 2.8% women). In multivariate analysis, AF was independently associated with slower TUG (ß 0.37; 95% confidence interval [CI] 0.07-0.71; P = .043) and slower usual gait speed (ß -3.59; 95% CI -7.05 to -0.12; P = .030). There was a significant age*AF interaction effect for usual gait speed (ß -0.480, 95% CI -0.907 to -0.053, P = .028). Adults with AF walked 3.77 cm/s more slowly than adults without AF at age 70, declining by 4.8 cm/s for each additional decade. CONCLUSION: AF is independently associated with lower usual gait speed in community-dwelling adults and this effect is magnified in those aged 70 and older. This may place them at increased risk of falls, hospitalization, cognitive decline, and mortality, as well as stroke and heart failure. Early recognition and treatment of AF is vital to improve physical function and reduce this risk.

SSRIs increase risk of blood transfusion in patients admitted for hip surgery.

BACKGROUND: Recent studies have shown that an increased bleeding tendency can be caused by Selective Serotonin Reuptake Inhibitors (SSRI) use. We aimed to investigate the occurrence and risk of blood transfusion in SSRI users compared to non-SSRI users in a cohort of patients admitted for hip-surgery. METHODS: We conducted a retrospective cohort study of patients who underwent planned or emergency hip surgery from 1996 to 2011 in the Academic Medical Center in Amsterdam. Primary outcome measure was risk of blood transfusion. Secondary outcome measures were pre- and postoperative hemoglobin level. Multivariate logistic regression was used to adjust for potential confounders. RESULTS: One-hundred and fourteen SSRI users were compared to 1773 non-SSRI users. Risk of blood transfusion during admission was increased for SSRI users in multivariate analyses (OR 1.7 [95% CI 1.1-2.5]). Also, pre-operative hemoglobin levels were lower in SSRI users (7.8 ± 1.0 mmol/L) compared to non-SSRI users (8.0 ± 1.0 mmol/L) (p  =  0.042)), as were postoperative hemoglobin levels (6.2 ± 1.0 mmol/L vs. 6.4 ± 1.0 mmol/L respectively) (p  =  0.017)). CONCLUSIONS: SSRI users undergoing hip surgery have an increased risk for blood transfusion during admission, potentially explained by a lower hemoglobin level before surgery. SSRI use should be considered as a potential risk indicator for increased blood loss in patients admitted for hip surgery. These results need to be confirmed in a prospective study.

Exploring the sensitivity of speech-in-noise tests for noise-induced hearing loss.

OBJECTIVE: Recently, the digit triplet test was shown to be a sensitive speech-in-noise test for early high-frequency hearing loss in noise-exposed workers. This study investigates if a further improvement is achieved when using a closed set of consonant-vowel-consonant (CVC) speech items with the same vowel, and/or a low-pass (LP) filtered version of the standard speech-shaped noise. DESIGN: Speech reception thresholds in noise were gathered for the digit triplet, CVC, and CVC_LP test and compared to the high-frequency pure-tone average (PTA). STUDY SAMPLE: 118 noise-exposed workers showing a wide range of high-frequency hearing losses. RESULTS: For the 84 Dutch-speaking participants, the CVC test showed an increased measurement error and a decreased between-subject variation, leading to a weaker correlation with the PTA2,3,4,6 (R = 0.64) and thus a lower sensitivity compared to the digit triplet test (R = 0.86). However, the use of LP-filtered noise resulted in a sensitivity improvement (R = 0.79 versus R = 0.64) due to the large increase in between-subject spread. Similar trends were found for the 34 French-speaking workers. CONCLUSIONS: Using CVC words with the same vowel could not increase the sensitivity to detect isolated high-frequency hearing loss. With LP-filtered noise, test sensitivity improved, but it did not surpass the original digit triplet test.

Development and validation of the Leuven intelligibility sentence test with male speaker (LIST-m).

OBJECTIVE: In addition to the LIST with a female speaker ( van Wieringen & Wouters, 2008 ), a new speech perception test with a male voice was developed and validated, for evaluating the intelligibility performance of cochlear implant (CI) users or severely hearing-impaired persons. DESIGN: Three experimental steps were carried out: (1) a perceptual optimization of the recorded materials, (2) an evaluation in normal-hearing (NH) listeners, and (3) a validation in CI-users. Measurements were performed both in quiet and in noise. STUDY SAMPLE: Forty-four NH subjects and six CI-users participated. RESULTS: After selecting the sentences with a similar intelligibility, the reference psychometric curve for NH listeners was determined, showing steep slopes for measurements in quiet (12.3%/dB) and in noise (18.7%/dB), similar to the LIST with female voice. The 38 lists of 10 sentences yielded equal scores, and the within-subject test-retest reliability was high (1.7 dB in quiet, 1.1 dB in noise). For the CI-users, parallel psychometric curves were found between the LIST with male and female voice. CONCLUSIONS: The LIST-m is a reliable and valid speech intelligibility test that can be used for CI-users, both in quiet and in noise.

Efficient hearing screening in noise-exposed listeners using the digit triplet test.

OBJECTIVES: Hearing screening in occupational medicine is generally based on pure-tone threshold audiometry. However, reliable and valid thresholds can only be obtained in a sound-proof room, using a high-quality, well-calibrated audiometer, and by a well-trained administrator. Thresholds also need to be determined for several audiometric frequencies. This makes the test time-consuming and expensive, which is not ideal for the screening of large populations. A Speech-In-Noise test (SPIN), by contrast, does not have the abovementioned requirements. Because it can be implemented as a quick automated self-test, possibly over the Internet, a SPIN test is highly advantageous for screening purposes. However, its sensitivity for (isolated) high-frequency hearing loss, as typically seen in noise-exposed listeners, was unclear up to present. In this study, the authors investigated the sensitivity and specificity of the Digit Triplet SPIN test for detecting and monitoring (early-stage) high-frequency hearing loss, and its similarity across two different language versions. DESIGN: One-hundred eighteen noise-exposed workers, representing a wide range from no to severe high-frequency hearing loss, completed the French or Dutch version of the broadband Digit Triplet self-test in an office-like room. Pure-tone thresholds, collected by a professional audiologist in favorable settings, served as the reference. RESULTS: The 84 Dutch-speaking participants showed a very strong linear relation between the reference and the Digit Triplet test, with the pure-tone average at 2, 3, 4, and 6 kHz as a strong predictor (R = 0.86) for the speech-reception threshold. The sensitivity and specificity to detect mild high-frequency hearing loss were 92% (61 of 66) and 89% (16 of 18), respectively. The area under the receiver operating characteristic (ROC) curve was very high (≥0.91) for several degrees of high-frequency hearing loss. With a within-subject standard deviation of only 0.8 dB, the Digit Triplet test also had a low measurement error. The results of the 34 French-speaking subjects showed a highly similar trend. CONCLUSIONS: The Digit Triplet test proves to have a high sensitivity and specificity for detecting different degrees of high-frequency hearing loss. Given its ease of use, this test is very suitable for screening purposes in occupational medicine, and potentially for the screening of adolescents at risk of recreational noise-induced hearing loss.

Comparison of three types of French speech-in-noise tests: a multi-center study.

OBJECTIVE: To compare results on the everyday sentence test 'FIST', the new closed-set sentence test 'FrMatrix', and the digit triplet screening test 'FrDigit3'. DESIGN: First, the FrMatrix was developed and normative values were obtained. Subsequently, speech reception thresholds (SRTs) for the three types of tests were gathered at four study centers representing different geographic regions in Belgium and France. STUDY SAMPLE: Fifty-seven normal-hearing listeners took part in the normative study of the FrMatrix, and 118 subjects, with a wide range of hearing thresholds, participated in the comparative study. RESULTS: Homogenizing the individual words of the FrMatrix with regard to their intelligibility resulted in a reference SRT of -6.0 (±0.6) dB SNR and slope at the SRT of 14.0 %/dB. The within-subject variability was only 0.4 dB. Comparison of the three tests showed high correlations between the SRTs mutually (>0.81). The FrMatrix had the highest discriminative power, both in stationary and in fluctuating noise. For all three tests, differences across the participating study centers were small and not significant. CONCLUSIONS: The FIST, the FrMatrix, and the FrDigit3 provide similar results and reliably evaluate speech recognition performance in noise both in normal-hearing and hearing-impaired listeners.

The French digit triplet test: a hearing screening tool for speech intelligibility in noise.

A French speech intelligibility screening test in noise that applies digit triplets as stimuli has been developed and evaluated for both telephone and broadband headphone use. After optimizing the speech material based on the intelligibility of the individual digits, norms for normal-hearing subjects were established. speech reception thresholds (SRTs) of -6.4 +/- 0.4 and -10.5 +/- 0.3 dB SNR, and slopes of 17.1 and 27.1 %/dB were obtained for telephone and broadband headphone presentation, respectively. The French digit triplet test by telephone was then implemented as an automatic self-screening test by home telephone, and further evaluated in normal-hearing and hearing-impaired listeners. A test-retest variability of 0.7 dB was found and the correlation between SRT and pure-tone average (PTA(0.5,1,2,4)) was 0.77. One month after launching the test, 20,000 calls were registered. It can be concluded that both versions of the newly developed test have steep slopes and small SRT differences across normal-hearing listeners. The screening test by telephone is highly reliable and proves to fulfill the need for an easily accessible and objective hearing screening.
