Skin exposure in geriatric care ? a comparison between observation and self-assessment of exposure

Water, soap, and hand-disinfectant exposure during the COVID-19 pandemic and self-reported hand eczema in frontline workers: A cross-sectional study

BACKGROUND

During the COVID-19 pandemic, increased hand hygiene practices were implemented. Impaired skin health on the hands among healthcare workers has been reported previously. Knowledge of how worker in other occupations have been affected is scarce.

OBJECTIVES

To investigate self-reported hand water-, and soap exposure and use of hand disinfectants, and hand eczema (HE) in frontline workers outside the hospital setting and in IT personnel during the COVID-19 pandemic.

METHODS

In this cross-sectional study, a questionnaire was sent out between 1 March and 30 April in 2021, to 6060 randomly selected individuals representing six occupational groups.

RESULTS

A significant increase in water exposure and hand disinfectant use was shown: Relative position (RP) 19; 95% confidence interval (CI) 0.17-0.21 and RP = 0.38: 95% CI 0.36-0.41, respectively. Newly debuted HE was reported by 7.4% of the population, more frequently among frontline workers (8.6%) compared to IT personnel (4.9%).

CONCLUSIONS

Water and soap exposure and use of hand disinfectants increased during COVID-19 pandemic, which may increase the risk of hand eczema. This highlights the importance of communication and implementation of preventive measures to protect the skin barrier also in occupations other than healthcare workers.

Causes of irritant contact dermatitis after occupational skin exposure: a systematic review

PURPOSE

Irritant contact dermatitis (ICD) is a major cause of occupational disease. The aim was to review the relation between exposure to occupational irritants and ICD and the prognosis of ICD.

METHODS

Through a systematic search, 1516 titles were identified, and 48 studies were included in the systematic review.

RESULTS

We found that the evidence for an association between ICD and occupational irritants was strong for wet work, moderate for detergents and non-alcoholic disinfectants, and strong for a combination. The highest quality studies provided limited evidence for an association with use of occlusive gloves without other exposures and moderate evidence with simultaneous exposure to other wet work irritants. The evidence for an association between minor ICD and exposure to metalworking fluids was moderate. Regarding mechanical exposures, the literature was scarce and the evidence limited. We found that the prognosis for complete healing of ICD is poor, but improves after decrease of exposure through change of occupation or work tasks. There was no substantial evidence for an influence of gender, age, or household exposures. Inclusion of atopic dermatitis in the analysis did not alter the risk of ICD. Studies were at risk of bias, mainly due to selection and misclassification of exposure and outcome. This may have attenuated the results.

CONCLUSION

This review reports strong evidence for an association between ICD and a combination of exposure to wet work and non-alcoholic disinfectants, moderate for metalworking fluids, limited for mechanical and glove exposure, and a strong evidence for a poor prognosis of ICD.

Wet work exposure: comparison of observed and self-reported data

PURPOSE

Wet work is the most important exposure leading to occupational hand eczema; however, the prevalence and character of wet work in various wet work professions remain not fully covered. Self-reported data are widely used in studies of wet work although the validity of these remains uncertain. The objective of the present study is to provide information on validity of self-reported wet work exposure in different professions by comparing work place observations with self-reported data.

METHODS

114 workers from 15 various wet work professions were observed. The observations covered duration and frequency of wet work activities. The observed population as well as a non-observed population from each work place were given a questionnaire covering the same wet work activities.

RESULTS

Correspondence analysis between self-reported and observed wet work showed that misclassification was larger regarding duration than frequency. 29.2% overestimated and 23.9% underestimated total wet work with more than 2 h/day. Professions with high wet work prevalence overestimated duration of wet work activities, but underestimated frequency. Females overestimated frequency, but not duration. The observed group (45%) significantly more often, than the non-observed group (32%), reported having more than 2 h of wet work/day (OR 2.8, 95% CI 1.6-4.9). Sensitivity and specificity of the questionnaire regarding total wet work in the observed population showed 51% sensitivity and 59% specificity.

CONCLUSION

Over- and underestimation of wet work were found to be equally distributed. The correspondence analyses illustrate a noticeable misclassification between the estimations and the observations on all wet work variables, but largest for total wet work.

Is skin exposure to water mainly occupational or nonoccupational? A population-based study

BACKGROUND

Skin exposure to water is considered to contribute to hand eczema. Knowledge about total water exposure during a day is scanty.

OBJECTIVES

To investigate self-reported water exposure at work as well as throughout the day.

METHODS

Skin exposure to water was assessed from two questionnaire-based health surveys: the nationwide Environmental Health Survey 2007 (EHS), which enquired about water exposure throughout the day, and the Stockholm Public Health Survey 2006 (PHS), which probed water exposure at work. Answers from 19,667 individuals (EHS) and 18,318 individuals (PHS) were available for analysis.

RESULTS

In total, 22% of respondents (women 30%, men 12%) reported skin exposure to water more than 20 times during an entire day (EHS) compared with 6% (women 8%, men 4%) at work (PHS). In a univariate analysis, using a merged file comprising data from the EHS and the PHS, water exposure more than 20 times a day was more common in the EHS (prevalence proportion ratio 3·570, 95% confidence interval 3·353-3·802). In multivariate models the variables studied did not fulfil the criteria for being confounders. Water exposure at work declined with increasing age in both women and men (P < 0·0001) as did water exposure during the entire day in men (P < 0·0001). However, women were equally exposed during the entire day across age groups (P = 0·205).

CONCLUSIONS

High water exposure over the entire day was found to be considerably more frequent than exposure at work. Thus, a significant proportion of water exposure seems to occur outside work. This should be considered in prevention of hand eczema and when counselling patients with hand eczema in clinical practice.

Wet work and hand eczema in apprentice nurses; part I of a prospective cohort study

BACKGROUND /OBJECTIVES

Environmental exposure and personal susceptibility both contribute to the development of hand eczema. Here, we report an investigation on wet work exposure and its influence on the risk of developing hand eczema in apprentice nurses.

METHODS

A prospective cohort study was performed among 721 Dutch apprentice nurses. Participants recorded wet work exposure and symptoms of hand eczema using specially designed diary cards.

RESULTS

For 533 apprentice nurses, a follow-up time of 1-3 years was completed. Diary cards were supplied by 383 students. The 1-year period prevalence of hand eczema was 23% in the first year, 25% in the second year and 31% in the third year of follow-up. Eighty-one new cases of hand eczema developed, most of which occurred during the first year of follow-up. In approximately one-third of the participants, wet work exposure exceeded the national guidelines. Frequent hand washing during traineeships [odds ratio (OR) 1.5; 90% confidence interval (CI) 1.0-2.3], frequent hand washing at home (OR 2.3; 90% CI 1.5-3.7) and having a side job involving wet work (OR 1.6; 90% CI 1.0-2.4) were independent risk factors for hand eczema.

CONCLUSION

As a considerable number of apprentice nurses had already developed hand eczema during traineeships, more attention should be paid to skin protection in vocational education.

Exposures related to hand eczema: a study of healthcare workers

BACKGROUND

Hand eczema is common in healthcare workers, owing to intensive exposure to wet work and skin irritants. Targeted interventions and vocational guidance based on documented exposures and risk factors are needed.

OBJECTIVES

The aims of the study were to investigate the relationship between exposures (domestic and at work) and prevalence and severity of hand eczema.

METHODS

Self-administered questionnaires were sent to 3181 healthcare workers in Denmark.

RESULTS

Two thousand two hundred and sixty-nine (71%) workers responded to the questionnaire. Frequent hand washing was significantly related to the presence of hand eczema. Having children < 4 years old in the household was also related to the presence of hand eczema. A lower prevalence of hand eczema was found among those using moisturizers at work, and a higher prevalence was found among those using moisturizers at home.

CONCLUSIONS

Although healthcare workers are recommended to use disinfectants when the hands are not visibly dirty, hand washing is still significantly related to hand eczema. Frequent hand washing may be a question of behavioural habits, and a focus for future guidance should be on changing hand washing habits. Attention should also be paid to healthcare workers with small children at home. The preventive effect of moisturizers used during working hours should be tested in future follow-up studies.

Skin exposure to epoxy in the pipe relining trade - an observational study

BACKGROUND

Epoxy resin systems (ERSs) are frequent causes of occupational allergic contact dermatitis. Epoxy pipe relining has become a widely used alternative to replacing old and worn drain pipes in housing, and involves a high risk of skin exposure to ERSs.

OBJECTIVES

To map out work methods, protective measures and skin and surface contamination among workers involved in epoxy pipe relining, as a basis for prevention of occupational skin disease.

METHODS

Twenty-one employees in eight relining companies in Stockholm County were observed. Contact and contamination with ERSs and the use of personal protective equipment during relining work were noted.

RESULTS

Contamination by uncured ERSs on gloves, personal and shared tools and work areas was identified during mixing, wetting, installation, and cleaning. The gloves used were often inadequate for handling ERSs.

CONCLUSIONS

Relining pipes poses an extensive risk of uncured ERS exposure, and contamination was identified during the whole work process. Shared and personal tools and work areas were extensively contaminated. Changes in work routines and logistics for handling ERSs are essential, and knowledge among both employers and employees regarding the risks caused by ERS exposure is vital to create a safe work environment and prevent contact allergies.

Occupational skin exposure to water: a population-based study

BACKGROUND

Occupational exposure to skin irritants, in particular to water, is an important risk factor for hand eczema.

OBJECTIVES

To assess occupational skin exposure to water in the general population.

METHODS

As part of a public health survey in Stockholm, Sweden, 18,267 gainfully employed individuals aged 18-64 years completed a questionnaire with previously validated questions regarding occupational skin exposure to water.

RESULTS

Altogether 16% reported exposure to water for (1/2) h or more a day, and 13% reported exposure to water more than 10 times a day. Furthermore, 7% reported water exposure of more than 2 h and 6% of more than 20 times a day. Women reported more water exposure than men and many female-dominated occupations were seen to comprise water exposure. Women were also more exposed than men within the same jobs. Young adults were more exposed than older. A total of 18% were employed in high-risk occupations for hand eczema. Fifty-nine per cent of individuals employed in high-risk occupations reported water exposure at work, compared with 11% in low-risk occupations.

CONCLUSIONS

A total of 20% of the population of working age acknowledged occupational skin exposure to water, which was found to be more common in young adults and women. Using job title as a proxy for water exposure gives an underestimation due to misclassification. In assessing occupational skin exposure to water, both exposure time and frequency should be considered.
