Associations between Hours Worked, Symptoms and Health Resource Utilization among Full‐time Male Japanese Workers

Examining associations between work-related injuries and all-cause healthcare use among middle-aged and older workers in Canada using CLSA data

INTRODUCTION

Prior studies examining the relationship between work- related injuries and healthcare use among middle-aged and older workers were mainly cross-sectional and reported inconsistent results.

OBJECTIVE

The objective of this study was to examine the associations between work-related injuries and 10 types of healthcare service use for any cause among middle-aged and older Canadian workers using longitudinal data.

METHODS

Our study involved longitudinal analysis of baseline and 18-month follow-up Maintaining Contact Questionnaire data from the Canadian Longitudinal Survey on Aging (CLSA) for a national sample of Canadian males and females aged 45-85 years who worked or were recently retired (N = 24,748).

RESULTS

Among CLSA participants who worked or were recently retired, 361 per 10,000 reported a work-related injury within the year prior to the survey. Work-related injuries decreased with increasing age. Work-related injury was associated with emergency department visits, overnight hospitalization, visits to dentists, and visits to physiotherapists, occupational therapists, or chiropractors at follow-up in bivariate analyses. Compared to those with no work-related injuries, Canadians with work-related injuries had used, on average, a significantly higher number of health services within the last 12 months prior their survey. When controlling for the contribution of various socio-demographic, work-related, and health-related characteristics, work-related injuries remained a significant predictor of emergency department visits and visits to physiotherapists, occupational therapists, or chiropractors.

CONCLUSIONS

The relationship between work-related injuries, emergency department visits, and visits to physiotherapists, occupational therapists, or chiropractors in middle-aged and older workers in Canada suggests that workplace injuries can be associated with ongoing health problems.

PRACTICAL APPLICATIONS

Healthcare services used by injured employees must be considered priorities for employment insurance coverage, if not already covered. Future research should more fully examine whether pre-existing health conditions predict both work-related injury and subsequent health problems. Injury-specific healthcare use following work-related injuries in middle-aged and older workers, as well as economic costs, should also be examined.

Impact of Long Working Hours and Shift Work on Unmet Health Care Need Among Korean Workers

Background

This study aimed to identify work-related risk factors, including long working hours and night/shift work, for unmet health care need using data of a representative panel of Korean adults.

Methods

Associations between work-related factors and unmet health care need were analyzed using data of 3,440 participants (10,320 observations) from the 2011-2013 Korean Health Panel Study. A generalized estimating equation was used for the analysis of repeated measures.

Results

The prevalence of unmet health care was 16.6%. After adjusting sex, age, socioeconomic status, work characteristics, and working more than 60 hours per week (odds ratio [OR]: 1.43, 95% confidence interval [CI]: 1.23–1.65) or 50–59 hours per week (OR: 1.26, 95% CI: 1.08–1.46) instead of 40–49 hours per week and night/shift work (OR: 1.27, 95% CI: 1.06–1.51) were associated with unmet health care need.

Conclusion

Long working hours and night/shift work are risk factors for unmet health care need among the Korean working population.

Occupational Health Services Improve Effective Coverage for Hypertension and Diabetes Mellitus at Japanese Companies

The World Health Organization (WHO) aims to enable all people to receive health services, and has proposed effective coverage (EC) as an index for this aim. EC refers to "the fraction of potential health gain that is actually delivered to the population through the health system, given its capacity," and is used to indicate the percentage of the population whose diseases are well controlled among those who require treatment or are receiving treatment. This study aimed to evaluate the effects of occupational health services on EC. We hypothesized that occupational health services provided to employees by full-time occupational health practitioners, such as occupational physicians and occupational health nurses, improve EC for hypertension, diabetes mellitus and hyperlipidemia compared to those services provided by part-time occupational health practitioners. We conducted a cross-sectional study to analyze the results of general medical examinations, personnel information, and medical expense claims in fiscal year 2011. A total of 91,351 male employees at a company group participated in the study. The EC for hypertension, diabetes mellitus and hyperlipidemia was measured and compared between the employees in workplaces with occupational health practitioners (OH group) and the employees in workplaces without occupational health practitioners (non-OH group). The EC for hypertension and diabetes mellitus was significantly greater in the OH group than in the non-OH group (aOR: 1.41, 95% CI: 1.20 - 1.66 for hypertension; aOR: 1.53, 95% CI: 1.17 - 2.00 for diabetes mellitus), while the EC for hyperlipidemia was comparable (aOR: 1.11, 95% CI: 0.92 - 1.34). Occupational health services provided by full-time occupational health practitioners greatly improve health management after a medical examination.

Key information providers, channels, and characteristics of Japanese consumers’ informed choices of over-the-counter medications

People need reliable information regarding over-the-counter medications (OTCs), so that they can independently make appropriate informed choices. The study aimed to identify the information providers and channels that have an impact on the purchase of OTCs, and to demonstrate the information needs of OTC purchasers, using these providers and channels, from the viewpoint of information characteristics such as specialty, objectivity, concreteness, comprehensiveness, individuality, and availability, focusing on the efficacy of OTCs and related safety information. A questionnaire survey of randomly sampled adults aged ≥20 was conducted at the Japan Drugstore Show 2012, hosted by the Japan Association of Chain Drug Stores. In this questionnaire, information was particularly limited to the efficacy and safety of OTCs. Multivariate logistic regression analysis was performed on data from 1743 respondents (1625 purchasers and 118 non-purchasers of OTCs) who obtained information on OTCs in their daily lives, to demonstrate the associations between the use of information providers and channels (predictor variables) and the purchase of OTCs (outcome variable), as well as between information characteristics valued by purchasers (predictor variables) and their use of these information providers or channels (outcome variables). Both the use of pharmacists as information providers and consultation at pharmacies as an information channel were positively associated with the purchase of OTCs (odds ratio [OR], 3.74; 95 % confidence interval [CI], 2.46–5.68; P < 0.001 and OR, 4.55; 95 % CI 2.92–7.11, P < 0.001, respectively), whereas both the use of family or friends using OTCs as information providers and family or friends as information channels were negatively associated with the purchase of OTCs (OR, 0.60; 95 % CI 0.40–0.90; P = 0.014 and OR, 0.55; 95 % CI 0.36–0.82; P = 0.004, respectively). OTC purchasers who valued individuality of information were more likely to use pharmacists (OR 2.00; 95 % CI 1.61–2.48; P < 0.001) and consultation at pharmacies (OR 1.98; 95 % CI 1.61–2.43; P < .001). In conclusion, individualized information provided by pharmacists on the efficacy and safety of OTCs during consultation at pharmacies can play the most important role in the informed choices of OTC purchasers.

Does time pressure create barriers for people to receive preventive health services?

OBJECTIVE

Regular use of recommended preventive health services can promote good health and prevent disease. However, individuals may forgo obtaining preventive care when they are busy with competing activities and commitments. This study examined whether time pressure related to work obligations creates barriers to obtaining needed preventive health services.

METHODS

Data from the 2002-2010 Medical Expenditure Panel Survey (MEPS) were used to measure the work hours of 61,034 employees (including 27,910 females) and their use of five preventive health services (flu vaccinations, routine check-ups, dental check-ups, mammograms and Pap smear). Multivariable logistic regression analyses were performed to test the association between working hours and use of each of those five services.

RESULTS

Individuals working long hours (>60 per week) were significantly less likely to obtain dental check-ups (OR=0.81, 95% CI: 0.72-0.91) and mammograms (OR=0.47, 95% CI: 0.31-0.73). Working 51-60 h weekly was associated with less likelihood of receiving Pap smear (OR=0.67, 95% CI: 0.46-0.96). No association was found for flu vaccination.

CONCLUSIONS

Time pressure from work might create barriers for people to receive particular preventive health services, such as breast cancer screening, cervical cancer screening and dental check-ups. Health practitioners should be aware of this particular source of barriers to care.
