Reporting of self-reported hand eczema as an occupational disease in hospital cleaners: A cross-sectional questionnaire-based study

BACKGROUND

Hand eczema (HE) is a prevalent disease among professional cleaners.

OBJECTIVES

To investigate how often cleaners have their self-reported HE, induced or worsened by cleaners' occupational activities, reported as an occupational disease to the authorities in Denmark and to identify reasons for underreporting. In addition, consultation by physicians and treatment for HE among cleaners were also investigated.

METHODS

This cross-sectional questionnaire-based study included hospital cleaners at three different hospitals in Region Zealand, Denmark.

RESULTS

We included 224 out of 234 cleaners from three hospitals (response rate: 96%). The lifetime prevalence of self-reported HE with onset in adulthood was 18.3% (n = 41), with cleaners believing every case to be caused or exacerbated by their occupation. Only 9.7% (n = 4/41) of the cases were reported as an occupational disease to the authorities. The most common reasons for non-reporting were a lack of perceived seriousness of the disease (40.5%) and unawareness of the risk of self-reported HE being of occupational origin (32.4%). Remarkably, only 75.7% (n = 28/37) of workers with unreported cases had consulted a physician at some point. Additionally, among cleaners who self-reported HE attributed or aggravated by their occupation, but not officially reported as such, only 56.8% (n = 21/37) had ever used hand moisturisers, while less than 45% had ever used topical steroids or calcineurin inhibitors.

CONCLUSION

Our findings reveal substantial underreporting of self-reported HE, perceived to be induced or worsened by the cleaner's occupational activities, as an occupational disease to the authorities.

Professional Cleaners' and Healthcare Workers' Ability to Recognize Hand Eczema

Timely intervention reduces the risk of a poor prognosis in hand eczema, making early recognition of symptoms important in high-risk professions. However, limited data exist regarding the ability of cleaners and healthcare workers to recognize hand eczema. The aim of this study was to examine cleaners' and healthcare workers' ability to recognize hand eczema in clinical photographs and to assess the severity of the disease. Cleaners and healthcare workers completed a questionnaire consisting of 16 questions and participated in a structured interview referring to a validated photographic severity guide for chronic hand eczema, which comprised clinical photographs of hand eczema at varying levels of severity. Eighty cleaners and 201 healthcare workers (total N = 281) participated in the study. The rates of correctly identified hand eczema in clinical photographs (cleaners/ healthcare workers) were: 41.2%/57.7% (mild hand eczema), 81.2%/92.0% (moderate hand eczema), 85.0%/94.5% (severe hand eczema) and 82.5%/97.0% (very severe hand eczema). The proficiency of healthcare workers in recognizing hand eczema was significantly higher than that of cleaners. The results indicate that a large proportion of cleaners and healthcare workers fail to recognize mild hand eczema in clinical photographs. Healthcare workers had higher success rates in recognizing hand eczema in all severity categories. Symptom underestimation may lead to under-reporting of the true prevalence of hand eczema, with consequent loss of opportunities for prevention.

Notification of hand eczema as an occupational disease among Danish hairdressers: a national survey on patients' perception

OBJECTIVES

Self-reported hand eczema was previously found under-reported as an occupational disease to the authorities among Danish hairdressers graduating from 1985 to 2007. This study investigates whether self-reported hand eczema among Danish hairdressers graduating from 2008 to 2018 is under-reported as an occupational disease to the authorities.

METHODS

A cross-sectional study on all Danish hairdressers graduating from 2008 to 2018 was conducted. The participants were identified using information from the Danish Hairdressers' and Beauticians' Union. In May 2020, a self-administered survey on hand eczema was sent to all hairdressers.

RESULTS

A response rate of 30.7% (1485/4830) was obtained. The lifetime prevalence of self-reported hand eczema was 40.1%, and 84.1% of hairdressers with hand eczema believed it to be occupational of whom 27.0% answered it was reported as an occupational disease to the authorities. Of hairdressers believing their hand eczema was occupational, consulting a doctor and answering it was reported as an occupational disease, 94.4% had consulted a dermatologist. The main reason for not reporting was 'I would probably not gain anything from it anyway' (40.0%).

CONCLUSIONS

Based on hairdressers' perception, occupational hand eczema still seems to be an under-reported disease which may lead to underestimation of the problem and impair prevention, diagnosis and treatment.

Diagnostics and Prevention of Occupational Allergy in Hairdressers

PURPOSE OF REVIEW

This study aims to provide an overview on current knowledge on occupational allergic diseases in hairdressers and up-to-date perspectives of prevention.

RECENT FINDINGS

Hand eczema (dermatitis) is common in hairdressers, often caused by contact allergy to one or multiple small molecules (haptens) used, e.g., for dyeing, bleaching, and waving/relaxing or by ancillary substances such as preservatives. Hairdressers, compared to other patch-tested patients, have an up to fivefold increased risk to be found sensitized, e.g., against p-phenylenediamine, ammonium persulfate, and glyceryl thioglycolate. Some of these small molecules may induce respiratory sensitization causing allergic rhinitis and/or asthma, notably persulfate salts. Occupational hazards in hairdressing are well described. This knowledge needs to be put into use for risk reduction, mainly by substitution of allergenic ingredients by less allergenic ones, education, and use of ventilation and suitable single-use gloves.

Aetiology of occupational hand eczema in hairdressers: Tackling the complexity of exposure combinations to identify patterns associated with increased risk of hand eczema

INTRODUCTION

Hairdressers are exposed to wet work and manifold allergens at work, rendering exposure complex and the aetiology of occupational hand eczema (OHE) often multifactorial in this occupational group.

OBJECTIVES

To identify exposure patterns associated with increased risk of hand eczema in hairdressers.

METHODS

All hairdressers graduating from 2004 to 2007 and 2015 to 2018 received a questionnaire in 2009 and 2020, respectively. Current exposures (with or without regular glove use) and OHE were self-reported, and their association examined. Patterns of exposure were identified by latent class analysis (LCA).

RESULTS

A total response of 39.9% (668/1675) was obtained. Six exposure profiles (#1-6) were identified by LCA across 11 tasks performed with or without gloves as well as deep conditioning, that is, 23 task items. Compared to profile #1 with the lowest OHE risk (reference) an increased risk of current OHE were seen in profile #4 [adjusted odds ratio [aOR] 6.5, 95% confidence interval [CI] 1.5-44.8 and #6 (aOR 39.4, 95%CI 6.1-362.8)] in logistic regression analysis. Profile #1 and #6 had performed the same tasks, but in profile #6 regular glove use was performed in 9.1% (1/ 11) of tasks compared to 72.7% (8/11) of tasks in profile #1 (p = 0.002).

CONCLUSION

Although occupational exposures in hairdressing are complex, meaningful patterns associated with a wide range of OHE risk can be identified by LCA. The increase of OHE risk seems predominantly to be due to poor compliance with protective gloves. LCA could be applied to further fields of complex (skin) exposures.

Artificial Nails and Long-lasting Nail Polish in Danish Hairdressers: Self-use, Occupational Exposure and Related Eczema

Artificial nail modelling systems (ANMS), encompassing artificial nails and long-lasting nail polish, are sources of acrylate exposure in beauticians and users of ANMS. Hairdressers' exposure to ANMS from self-use and occupational exposure is currently unknown. In 2020 a questionnaire was sent to all hairdressers graduating during 2008 to 2018 in Denmark (n = 4,830). Self-use of ANMS was reported by 87.6% of respondents (1,251/1,428), and application of ANMS to others was reported by 22.1% (316/1,428). Of these, application to others was performed in a salon by 37.1% (109/294), privately by 51.0% (150/294) and in both settings by 11.9% (35/294). Compliance with glove use was seen in 23.0% (67/291) among those applying ANMS to others. Among hairdressers exposed to ANMS, 4.3% (52/1,218) reported ANMS-related hand eczema. Being a trained beautician (adjusted odds ratio 3.26, 95% confidence interval 1.06-9.99) and having had a positive patch-test to acrylates (adjusted odds ratio 7.70, 95% confidence interval 1.44-41.13) were associated with ANMS-related hand dermatitis. In conclusion, hairdressers have a high prevalence of exposure to ANMS and ANMS-related hand dermatitis. Compliance with glove use when applying ANMS to others is poor. Patch-testing with acrylates is valuable in the diagnostic work-up of hand eczema in hairdressers.
