[Disease due to work can be prevented more often; an alert report from The Netherlands Centre for Occupational Diseases]. / Ziekte als gevolg van arbeid vaker te voorkomen; signaleringsrapport van het Nederlands Centrum voor Beroepsziekten.

Epidemiologic data on occupational diseases in the Netherlands are scarce, partly because of the lack of 'risques professionnels' in the Dutch social security system. The Netherlands Centre for Occupational Diseases (NCvB) provides an annual overview of the occurrence and distribution of occupational diseases by sector and occupation. Like in other western countries, the number of reports of occupational diseases has decreased the last few years. Recent data, however, suggest a small increase. The NCvB also provides warning signals, which this centre believes should be known to health and safety policymakers and professionals so that they may respond with appropriate action. The report gives 4 different alerts: on the importance of health and safety awareness during vocational training, on scientific evidence in support of zero tolerance for intimidation and violence, on health and safety consultation regarding conception and pregnancy, which should focus on both men and women, and on the poor working conditions at the bottom end of the labour market. These alerts may also be of special interest to general practitioners and medical specialists because it is they who are primarily confronted with workers and their health problems as mentioned in the alerts.

Characteristics of wet work in nurses.

BACKGROUND OBJECTIVES: Nursing is known for its high prevalence of hand dermatitis, mainly caused by the intense exposure to wet work in nursing activities. We aimed to study the characteristics of wet work exposure in nursing. METHOD: Trained observers monitored the duration and frequency of different wet work activities in 45 randomly chosen nurses from different wards during a morning shift, using a method of continuous observation based on labour-observation techniques. RESULTS: Wet work in intensive care units accounted for 24% of the overall morning shift duration, with a frequency of 49 incidents. This was 16% in dialysis wards, with a frequency of 30 incidents, and 9% on regular wards, with a frequency of 39 incidents. The wet work activities had short mean duration cycles. The mean duration of occlusion by gloves was 3.1 min on regular wards and 6.7 min in intensive care units. DISCUSSION: The characteristics of wet work in nurses differed substantially, depending on the ward. According to the German regulation TRGS 531, our observations classify nursing as a wet work occupation, due to the frequency of wet work rather than its duration. The mean duration of occlusion in our observations was short, which makes an occlusion-induced irritating effect doubtful. Reduction in wet work exposure in nursing on regular wards could focus on the reduction of the frequency of hand-washing and patient-washing. We suggest increasing the use of gloves for patient washing. Although this will increase exposure to occlusion from gloves, it may reduce the frequency of exposure to water and soap by about a quarter.

Skin disease in paper mill workers.

BACKGROUND: Paper mill workers have frequent and prolonged exposure to skin irritants and allergens and may have a higher risk of developing occupational dermatitis. Aims The aim of this study was to determine the extent of skin problems in a paper mill and how much was attributable to contact with allergens. METHODS: A cross-sectional study was carried out among 80 paper mill workers having daily exposure to skin irritants and allergens. They all completed a questionnaire, underwent a standard interview and physical examination. Workers whose history indicated possible contact allergy were patch tested and prick tested. RESULTS: Workers reported a high exposure to skin irritants, especially when carrying out tasks that caused the hands and feet to become wet from perspiration and having contact with process water. Atopic dermatitis was seen in 3% of the workers. Contact dermatitis was seen in 26% of the workers and 36% were diagnosed with mycosis of the feet. All cases of contact dermatitis and mycosis could be attributed to occupational exposure to skin irritants. No cases of relevant contact allergy were seen. CONCLUSION: Occupational dermatitis in paper mills is primarily related to the exposure to skin irritants. Occupational physicians should be aware of the risk of occupational dermatitis in paper mill workers.

Characteristics of wet work in the cleaning industry.

Wet work is the main cause of occupational contact dermatitis in the cleaning industry. Dermatologists and occupational physicians need to base their primary and secondary prevention for workers in the cleaning industry on the characteristics of wet work exposures. We quantified the burden of wet work in professional office cleaning activities with a continuous standardized observation by trained observers of 41 office cleaners. Duration and frequency of wet work exposure and of different cleaning activities were assessed. Wet work made up 50% of such cleaning work. Within a typical 3-hr shift, a mean frequency of 68 episodes of wet work was observed, which classifies office cleaning as wet work. Skin exposure to irritants was markedly different among cleaners who did the same cleaning activities. Reduction in skin irritation can be achieved by training the workers. Because this group of workers, who have a low level of education, has a high risk of developing irritant hand dermatitis, a special effort on training and instruction should be made. A reduction of exposure can be achieved by: using gloves more often; using gloves for a shorter period of time; using gloves while doing activities that otherwise cause the skin to be in contact with water and cleaning substances and washing hands with water only, reserving soap for when the hands are visibly dirty.

Skin protection in nursing work: promoting the use of gloves and hand alcohol.

Nursing has been identified as a wet-work occupation, with a high prevalence of occupational irritant contact dermatitis. Reduction of exposure to skin irritants contributes to the prevention of occupational skin disease in nurses. The role of the use of soap and water, hand alcohol and gloves in prevention programmes is discussed. 2 additional measures for reducing exposure to skin irritants are postulated: use of hand alcohol instead of soap and water in disinfection procedures when the hands are not visibly dirty; use of gloves in wet activities such as patient washing to prevent the hands from becoming wet and visibly dirty. We investigated the effectiveness of these recommendations in a model. Mean daily wet-work exposure during nursing work was modelled: regular model. We also modelled exposure to skin irritants in combination with the implementation of these recommendations: prevention model. The hands of healthy volunteers were exposed to the regular or the prevention model over 3 weeks for 5 days a week. The change in transepidermal water loss (TEWL) on the back of the hands was measured after 3 weeks of exposure to these wet-work simulations. An increase in TEWL occurred with the regular model, while mean TEWL decreased in the prevention model. Skin irritation from occlusion by gloves appeared to be more pronounced in the regular model compared to the prevention model. The results of this study justify the conclusion that in nursing work, hand alcohol is the preferred disinfectant. Although the prevention model implies increased occlusive exposure, this has no additional irritant effect, probably because of the absence of soap exposure.

Exposure of the hands to wet work in nurses.

Prevention of hand dermatitis among nurses can be achieved by reduction of wet-work exposure. A preventive programme should be based on knowledge of exposure levels. An accurate method to assess such exposure levels is needed. Duration and frequency of wet-work activities were assessed by a questionnaire, in various parts of the health care sector. In addition, a randomly chosen sample from this population was observed for the duration and frequency of wet work. In contrast to the questionnaire, the observation method showed less than half the duration of wet work. Observation detected almost double the frequency that was reported with the questionnaire. Gloves were observed to be used daily in special care units for short time periods. A questionnaire does not accurately assess the quantity of wet-work activities. On regular wards, the exposure to irritants is mainly associated with the frequency of wet hands, rather than the duration of wet hands. We assume that the short-term use of gloves on special care units does not cause an increased risk of hand dermatitis. Preventive programmes can focus on decreasing the frequency of wet hands by encouraging the use of gloves; the use of gloves should not only be advised to prevent infections but also to protect against hand dermatitis.

Irritant hand dermatitis: severity of disease, occupational exposure to skin irritants and preventive measures 5 years after initial diagnosis.

Irritant contact dermatitis (ICD) is often chronic; its aetiology frequently being related to occupational exposure. Management of ICD involves persistent reduction in exposure to skin irritants such as water, detergents and prolonged occlusion by gloves. The aim of this study was to determine the severity of hand dermatitis 5 years after initial diagnosis and to find out what factors were related to this outcome. A questionnaire survey was carried out on severity of hand dermatitis, exposure to skin irritants and preventive measures, 5 years after initial ICD diagnosis. Of a cohort of 201 patients with ICD, 172 received the questionnaire and 124 (72%) responded. 5 years after initial diagnosis, 50% still had medium and 32% severe hand dermatitis. Patients with severe ICD and high exposure showed low levels of prevention and difficulty in changing their occupational exposure. Use of emollients was predominantly therapeutic rather than preventive. Occupation was changed in 57% of cases, of which 46% was permanent. In this population, ICD is a chronic disease; implementation of secondary preventive measures appears to fail. In occupations with high exposure to skin irritants, implementation of permanent exposure reduction is more difficult, compared to occupations with a medium level of exposure. High exposures might have led to change of occupation; medium exposures could have been reduced to low levels. In occupations with high exposure, women were overrepresented.
