Mortality of people with intellectual disabilities during the 2017/2018 influenza epidemic in the Netherlands: potential implications for the COVID-19 pandemic.

BACKGROUND: Data on the development of Covid-19 among people with intellectual disabilities (IDs) are scarce and it is uncertain to what extent general population data applies to people with ID. To give an indication of possible implications, this study investigated excess mortality patterns during a previous influenza epidemic. METHODS: Using Dutch population and mortality registers, a historical cohort study was designed to compare mortality during the 2017-2018 influenza epidemic with mortality in the same period in the three previous years. People with ID were identified by entitlements to residential ID-care services as retrieved from a national database. RESULTS: Data covered the entire adult Dutch population (12.6 million; GenPop), of which 91 064 individuals were identified with an ID. During the influenza epidemic, mortality among people with ID increased almost three times as much than in the GenPop (15.2% vs. 5.4%), and more among male individuals with ID (+19.5%) than among female individuals with ID (+10.6%), as compared with baseline. In both cohorts, comparable increases in mortality within older age groups and due to respiratory causes were seen. Particularly in the ID-cohort, excess deaths also occurred in younger age groups, due to endocrine diseases and ID-specific causes. CONCLUSIONS: During the 2017-2018 influenza epidemic, excess mortality among people with ID was three times higher than in the general Dutch population, appeared more often at young age and with a broader range of underlying causes. These findings suggest that a pandemic may disproportionally affect people with ID while population data may not immediately raise warnings. Early detection of diverging patterns and faster implementation of tailored strategies therefore require collection of good quality data.

Longitudinal Associations Between Fatigue and Perceived Work Ability in Cancer Survivors.

Purpose To examine the associations between changes of fatigue and changes of perceived work ability in cancer survivors. Furthermore, to examine the effects of physical job demands on these associations. Methods Data from a feasibility study on a multidisciplinary intervention to enhance return to work in patients with cancer receiving chemotherapy was used. Fatigue (Multidimensional Fatigue Inventory) and perceived work ability (first item of the Work Ability Index) were assessed at baseline, and after 6, 12, and 18 months. Change scores (S1, S2, S3) from each assessment to the next were calculated, thus encompassing three separate time periods of 6 months. Regression analyses were used to quantify associations between change of perceived work ability and (model 1) change of general fatigue, and (model 2) change of mental and physical fatigue for each 6-month period separately. For model 2, interaction effects of perceived physical job demands were studied. Results A total of 89 participants were included for analysis, among which 84% with a diagnosis of breast cancer. On average, in model 1, a reduction of five points on general fatigue was associated with an improvement of one point in perceived work ability in all three 6-month periods. Model 2 showed, similarly, that change of physical fatigue (S1 and S2: B = - 0.225; p < .001 and B = - 0.162; p = .012) and change of mental fatigue (S3: B = - 0.177; p = .027) were significantly inversely associated with change of perceived work ability. Interaction effects were not significant. Conclusion The inverse, longitudinal association between fatigue and perceived work ability supports previous findings from cross-sectional studies and shows potential occupational impact of targeting fatigue in cancer rehabilitation.

Value of work for employees with a chronic disease.

Background: Most people with a chronic disease value participation in work. Knowledge is limited, however, as to what extent employees with a chronic disease value participating in work, and the main reasons for this. Limited research is available on which specific factors contribute to the perceived value of work. Aims: To evaluate main reasons for, and the extent to which employees with a chronic disease value participation in work, and factors which motivate or demotivate employees in work. Methods: A survey of members of three large patient federations was performed. Respondents had a chronic disease and were of working age. The extent and reasons for valuing work were analysed using descriptive statistics; (de)motivating aspects were qualitatively analysed using specific software. Results: The 1683 respondents valued work with an average of 8 on a scale from 1 to 10 (1: 'work is not at all important to me' and 10: 'work is extremely important to me'). Most frequent reported reasons for valuing work were the provision of income, social contact and the ability to contribute to society. Motivational aspects for work were being financially independent, having positive social contact with colleagues or clients and having the ability to contribute to society. In contrast, negative social contact, performing useless work and having little autonomy demotivated people. Conclusions: Employed people with a chronic disease generally value work, mainly because it makes them financially independent, provides social contact and enables them to contribute to society.

Feasibility of a multidisciplinary intervention to help cancer patients return to work.

This study evaluates feasibility of a multidisciplinary intervention combining occupational counselling with physical exercise to enhance cancer patients' return to work, assesses whether care providers and patients were satisfied with the intervention, and describes barriers to and facilitators of execution. Newly diagnosed cancer patients, treated with chemotherapy and on sick leave from (self-)employment participated. Patients received counselling from an oncological occupational physician (OOP), were assessed by a sports physician, and performed a 12-week training programme supervised by physiotherapists. Care providers completed registration forms to collect data on reach, dose delivered and received in executing the protocol and were interviewed about their satisfaction and barriers to and facilitators of execution. Patients completed three questionnaires on satisfaction and usefulness of the intervention. Fifty-six per cent of all patients were eligible (reach). In total, 123 patients participated. For all intervention components dose delivered exceeded 75%; dose received ranged from 49%-79%. Overall, patients and care providers were satisfied and perceived the intervention as useful. Care providers considered the intervention feasible, while execution was facilitated by highly motivated patients and impeded by physical limitations hindering exercise. It is feasible to conduct this multidisciplinary intervention in cancer patients during curative treatment. Patients and care providers were satisfied with the intervention.

Predictors for earlier return to work of cancer patients.

PURPOSE: This study aims to investigate how perceived work ability, job self-efficacy, value of work, and fatigue predict return to work (RTW) in cancer patients who received chemotherapy. METHODS: Data of a before-after study on a multidisciplinary intervention that aimed to enhance RTW was used, consisting of four assessments up to 18 months. Time to partial and full RTW of 76 and 81 participants, respectively, was analyzed in Cox proportional hazard analysis with time-dependent variables. Univariate analyses of work ability, job self-efficacy, value of work, or fatigue as covariates were succeeded by multivariate analyses of work ability and either job self-efficacy, value of work, or fatigue as covariates. RESULTS: Participants were mostly female (93%), and diagnosed with breast cancer (87%). Most participants were permanently employed (84%) and 48% was sole breadwinner. When adjusted for timing variables and prognostic factors, all hypothesized factors were predictive for earlier RTW (p < .05). In models that also included work ability, only job self-efficacy significantly predicted earlier full RTW: hazard ratio = 1.681; p = .025. CONCLUSIONS: Lower fatigue and higher value of work, work ability, and job self-efficacy of cancer survivors are associated with earlier RTW. Work ability and job self-efficacy seem to be key predictors. IMPLICATIONS FOR CANCER SURVIVORS: Limiting fatigue, increasing value of work, job self-efficacy, and perceived work ability are promising goals for enhancing earlier RTW. Occupational rehabilitation should empower patients to organize appropriate conditions for work and to educate them on rights and obligations during sick leave.

A retrospective analysis of noise-induced hearing loss in the Dutch construction industry.

PURPOSE: Noise exposure is an important and highly prevalent occupational hazard in the construction industry. This study examines hearing threshold levels of a large population of Dutch construction workers and compares their hearing thresholds to those predicted by ISO-1999. METHODS: In this retrospective study, medical records of periodic occupational health examinations of 29,644 construction workers are analysed. Pure-tone audiometric thresholds of noise-exposed workers are compared to a non-exposed control group and to ISO-1999 predictions. Regression analyses are conducted to explore the relationship between hearing loss and noise intensity, noise exposure time and the use of hearing protection. RESULTS: Noise-exposed workers had greater hearing losses compared to their non-noise-exposed colleagues and to the reference population reported in ISO-1999. Noise exposure explained only a small proportion of hearing loss. When the daily noise exposure level rose from 80 dB(A) towards 96 dB(A), only a minor increase in hearing loss is shown. The relation of exposure time and hearing loss found was similar to ISO-1999 predictions when looking at durations of 10 years or more. For the first decade, the population medians show poorer hearing than predicted by ISO-1999. DISCUSSION: Duration of noise exposure was a better predictor than noise exposure levels, probably because of the limitations in noise exposure estimations. In this population, noise-induced hearing loss was already present at the beginning of employment and increased at the same rate as is predicted for longer exposure durations.
