Acceptance of semipermeable glove liners compared to cotton glove liners in health care workers with work-related skin diseases: Results of a quasi-randomized trial under real workplace conditions.

BACKGROUND: Glove liners (GLs) made of cotton (COT) are worn under impermeable gloves to prevent occlusion effects. Semipermeable GLs made of Sympatex (SYM) might be an alternative. OBJECTIVES: To evaluate the acceptance of GLs (COT/SYM) in health care workers (HCWs) with work-related skin diseases (WRSDs). METHODS: One hundred sixty-one HCWs with WRSDs were asked to wear GLs in combination with occlusive gloves for 10 ±2 weeks under workplace conditions. A questionnaire was applied to compare acceptance and usability of the respective glove combinations and previously used protective gloves (PUGs). RESULTS: A total of 120 data sets were available (SYM: n = 65, 77.4%; COT: n = 55, 71.4%). Both GLs provided a significantly lower sweating sensation, more pleasant climate, comfortable wearing experience, and moist or dry feeling on the skin compared to PUGs. SYM-GLs performed significantly better than COT-GLs regarding mobility of hands, sensitivity, and sense of touch. COT-GLs were significantly better than SYM-GLs in the categories fit, donning and doffing, and material contact. CONCLUSIONS: Both GLs did not impair work performance, were applicable in various areas of health care activities, and were preferred over PUGs. Our results indicate that SYM-GLs are an alternative to COT-GLs and thus may contribute to current prevention strategies.

The Effect of COVID-19 on Israeli Ophthalmology Departments: Directors' Perspectives.

BACKGROUND: The coronavirus disease-2019 (COVID-19) pandemic presented a major medical management challenge to ophthalmology departments throughout Israel. OBJECTIVES: To examine the managerial challenges, actions taken, and insights of directors of ophthalmology departments in Israel during the COVID-19 pandemic. METHODS: We conducted a cross sectional survey of directors of ophthalmology departments during the COVID-19 pandemic while the Israeli population was quarantined. RESULTS: All 21 directors answered the survey. The majority of the COVID-19 admissions were located in the center of Israel (53%) and Jerusalem (30%). E-communication took a central role in coping with the pandemic with 80% of the directors satisfied with this form of communication; 75% reported a reduction in clinical and surgery volume of at least 25%, and 40% reported reallocations of manpower. Most of the medical staff used gloves, a face shield, disposable robe, and a mask with no uniformity across departments. Cross satisfaction was noted regarding a hospital's ability to equip the departments. Lack of preparation for post-pandemic era was reported by all directors, but one (95%). Directors sought guidelines and uniformity regarding outpatient referral to the hospital (p = 0.035). CONCLUSIONS: Guidelines via safe digital platforms aid in management decisions and uniformity across departments. Advanced preparation is needed to prevent adverse clinical outcomes and to maintain treatment continuum. Our results can be used to guide and help improve the preparedness of ophthalmology departments during COVID-19 and for future pandemics.

Implementation of a Warm Zone Model During the COVID-19 Pandemic.

ABSTRACT: In March 2020, in response to the coronavirus disease 2019 (COVID-19) pandemic, the executive leadership of an academic medical center in Atlanta tasked an interprofessional quality improvement (QI) team with identifying ways to improve staff and patient safety while caring for patients with suspected or confirmed COVID-19 infection. Additional goals of the initiative were to improve workflow efficiency by reducing the amount of time spent donning and doffing personal protective equipment (PPE) and to conserve PPE, which could be in short supply in a prolonged pandemic. The QI team developed a "warm zone model" that allowed staff members to wear the same mask, eye protection, and gown while moving between the rooms of patients who had tested positive for COVID-19. The risk of self-contamination while doffing PPE is well documented. Staff members were trained to conserve PPE and to properly change gloves and perform hand hygiene between exiting and entering patients' rooms. The warm zone model allowed multidisciplinary team members to reduce the times they donned and doffed PPE per shift while maintaining or increasing the times they entered and exited patients' rooms. Staff members believed that the model improved workflow and teamwork while maintaining staff members' personal safety. Daily gown use decreased on the acute care unit where the model was employed, helping to preserve PPE supplies. Once the model was proven successful in acute care, it was modified and instituted on several critical care COVID-19 cohort units.

Prepregnancy handling of antineoplastic drugs and risk of miscarriage in female nurses.

PURPOSE: To examine the association betweenantineoplastic drug (AD) handling and risk of miscarriage. METHODS: Nurses' Health Study-3 participants self-reported AD administration and engineering controls (ECs) and personal protective equipment (PPE) use at baseline. We estimated the hazard ratio (HR) of miscarriage in relation to baseline AD handling using multivariable Cox proportional regression. RESULTS: Overall, 2440 nurses reported 3327 pregnancies, with 550 (17%) ended in miscarriages. Twelve percent of nurses self-reported currently handling AD and 28% previously handling AD. Compared with nurses who never handled AD, nurses who handled AD at baseline had an adjusted HR of miscarriage of 1.26 (95% confidence interval [CI], 0.97-1.64). This association was stronger after 12-weeks gestation (HR=2.39 [95% CI, 1.13-5.07]). Nurses who did not always use gloves had HR of 1.51 (95% CI, 0.91-2.51) compared with 1.19 (95% CI, 0.89-1.60) for those always using gloves; nurses who did not always use gowns had HR of 1.32 (95% CI, 0.95-1.83) compared with 1.19 (95% CI, 0.81-1.75) for nurses always using gowns. CONCLUSIONS: We observed a suggestive association between AD handling and miscarriage, particularly among nurses who did not consistently use PPE and EC with stronger associations for second trimester losses.

Association between personal protective equipment and SARS-CoV-2 infection risk in emergency department healthcare workers.

BACKGROUND AND IMPORTANCE: Healthcare personnel working in the emergency department (ED) is at risk of acquiring severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2). So far, it is unknown if the reported variety in infection rates among healthcare personnel is related to the use of personal protective equipment (PPE) or other factors. OBJECTIVE: The aim of this study was to investigate the association between PPE use and SARS-CoV-2 infections among ED personnel in the Netherlands. DESIGN, SETTING AND PARTICIPANTS: A nationwide survey, consisting of 42 questions about PPE-usage, ED layout - and workflow and SARS-CoV-2 infection rates of permanent ED staff, was sent to members of the Dutch Society of Emergency Physicians. Members were asked to fill out one survey on behalf of the ED of their hospital. The association between PPE use and the infection rate was investigated using univariable and multivariable regression analyses, adjusting for potential confounders. OUTCOME MEASURES: Primary outcome was the incidence of confirmed SARS-CoV-2 infections among permanent ED staff between 1 March and 15 May 2020. RESULTS: Surveys were sent to 64 EDs of which 45 responded (70.3%). In total, 164 ED staff workers [5.1 (3.2-7.0)%] tested positive for COVID-19 during the study period compared to 0.087% of the general population. There was significant clustering of infected ED staff in some hospitals (range: 0-23 infection). In 13 hospitals, an FFP2 (filtering facepiece particles >94% aerosol filtration) mask or equivalent and eye protection was worn for all contacts with patients with suspected or confirmed SARS-CoV-2 during the whole study period. The unadjusted staff infection rate was higher in these hospitals [7.3 (3.4-11.1) vs. 4.0 (1.9-6.1)%, absolute difference + 3.3%]. Hospital staff testing policy was identified as a potential confounder of the relation between PPE use and confirmed SARS-CoV-2 infections (collinearity statistic 0.95). After adjusting for hospital testing policy, type of PPE was not associated with incidence of COVID 19 infections among ED staff (P = 0.40). CONCLUSION: In this cross-sectional study, the use of high-level PPE (FFP2 or equivalent and eye protection) by ED personnel during all contacts with patients with suspected or confirmed SARS-CoV-2 does not seem to be associated with a lower infection rate of ED staff compared to lower level PPE use. Attention should be paid to ED layout and social distancing to prevent cross-contamination of ED personnel.

[Selected hand skin characteristics of laboratory diagnosticians]. / Wybrane cechy skóry dloni diagnostów laboratoryjnych.

BACKGROUND: Chronic skin exposure to a wet work environment, as well as disinfectants are factors contributing to epidermal barrier damage. This disturbs its protective functions and promotes the development of dermatoses. All these factors occur in the work environment of a laboratory diagnostician. The aim of the paper was to analyze selected skin parameters and skin lesions in the hands of laboratory diagnosticians. MATERIAL AND METHODS: Overall, 50 laboratory diagnosticians employed in a laboratory in Kraków, Poland, took part in the study. After the interview, the skin pH and moisture content were examined. Measurements were performed on the dorsal side of the dominant hand using the Skin-ph-Meter® PH 905 and Corneometer® CM 825 devices. RESULTS: The obtained moisture level values were qualified as dry or very dry skin, and the skin pH was within the reference range. No correlation between the skin pH value and the features examined (professional experience, the number of hours spent in protective gloves during the day, the number of hand washing episodes during the day) was not indicated. The level of skin moisture content seems to positively correlate with the time of wearing gloves. The use of hand moisturizers after each hand washing episode correlated with the level of skin moisture content. CONCLUSIONS: During the COVID-19 pandemic, this professional group has been facing huge challenges, and mental and physical stressors (including wet work environment) will be the source of future occupational diseases.

Instant killing of pathogenic chytrid fungi by disposable nitrile gloves prevents disease transmission between amphibians.

To prevent transmission of the pathogenic chytrid fungi Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal), hygiene protocols prescribe the single use of disposable gloves for handling amphibians. We discovered that rinse water from nitrile gloves instantly kills 99% of Bd and Bsal zoospores. Transmission experiments using midwife toads (Alytes obstetricans) and Bd, and Alpine newts (Ichthyosaura alpestris) and Bsal, show that the use of the same pair of gloves for 2 subsequent individuals does not result in significant transmission of any chytrid fungus. In contrast, handling infected amphibians bare-handed caused transmission of Bsal in 4 out of 10 replicates, but did not result in transmission of Bd. Based on the manufacturer's information, high resolution mass spectrometry (HRMS) and colorimetric tests, calcium lactate and calcium nitrate were identified as compounds with antifungal activity against both Bd and Bsal. These findings corroborate the importance of wearing gloves as an important sanitary measure in amphibian disease prevention. If the highly recommended single use of gloves is not possible, handling multiple post-metamorphic amphibians with the same pair of nitrile gloves should still be preferred above bare-handed manipulation.

Changes in dermatological complaints among healthcare professionals during the COVID-19 outbreak in Turkey.

INTRODUCTION: This questionnaire study evaluates dermatological complaints that may arise due to hygiene measures and anxiety among healthcare professionals (HCPs) during the COVID-19 outbreak. METHODS: A total of 526 volunteers, consisting of doctors and nurses, participated. Demographic features, personal hygiene behavior, personal protective equipment (PPE) use, Hospital Anxiety and Depression Scale-Anxiety (HADS-A) parameters, and symptoms of various dermatological diseases (xerosis, eczema, acne, hair loss, palmar hyperhidrosis, xeromycteria, urticaria, aphthous stomatitis, and seborrheic dermatitis) were investigated. RESULTS: Although the frequency and severity of many dermatological complaints increased during the pandemic period, the most frequent increase was observed in the frequency of complaints suggesting xerosis and eczema. We found that complaints suggesting xerosis and eczema were seen on the hands 2.44 and 3.57 times, respectively, as a result of washing hands 10 times/day, and that handwashing times of 10 seconds or more significantly increased the risk of eczema (5.44 times). Another remarkable result was a fivefold increase in acne complaints among those using any mask. The severity of all complaints except hair loss and seborrheic dermatitis correlated significantly with HADS-A. CONCLUSIONS: Our study showed that the frequency and severity of some dermatological complaints increased in HCPs.

Use of protective gloves by hairdressers: A review of efficacy and potential adverse effects.

Occupational hand eczema is common among hairdressers, and protective gloves are important in limiting exposure to irritants and allergens. Various glove types may differ in their protective ability, and their use may lead to hand eczema due to skin irritancy and allergy. MEDLINE was searched for studies investigating permeation of gloves to irritants and allergens used in the hairdressing trade, as well as adverse effects of glove use affecting hairdressers. Forty-four studies were identified; nine reported on permeation. Of those, two in vitro studies found nitrile rubber (NR) gloves to give the best protection when handling hair dyes. Polyethylene (PE) gloves had the lowest reported break-through time. The prevalence of sensitization to rubber materials in European hairdressers was as follows: thiuram mix, median 2.5% (range 0%-8.2%), weighted average 3.0% (95% confidence interval [CI] 3.0%-3.1%); mercapto mix, median 0.4% (range 0%-3.3%), weighted average 0.5% (95% CI 0.47%-0.50%), mercaptobenzothiazole, median 0.6% (range 0%-6.6%), weighted average 0.7% (95% CI 0.6%-0.7%), NRL-type I allergy, median 1.3% (range 1%-16.4%), weighted average 4.0% (95% CI 3.6%-4.5%). In conclusion, NR gloves provide the best skin protection for hairdressers, although natural rubber latex (NRL) and polyvinylchloride (PVC) gloves may be sufficient in most cases. PE gloves are not recommended. Synthetic rubber gloves with low or no levels of accelerators are preferred.

Hand Dermatitis in Nursing Students.

OBJECTIVE: To determine the frequency of self-reported hand dermatitis and the factors influencing its prevalence among nursing students. METHODS: Researchers collected demographic data and used a self-assessment form to identify dermatologic symptoms. The questionnaires were distributed to the students and collected again after the students completed the forms. RESULTS: Hand dermatitis was present in 20.9% of nursing students. The most common symptoms were irritation/pruritus, redness/cracking, flaking/rash, swelling, and vesicles in hands. The grade of the student, the presence of allergy complaints, and medication used to treat dermatitis were statistically significantly associated with dermatitis prevalence. The use of gloves and cleansing agents used in handwashing were factors linked to hand dermatitis. CONCLUSIONS: Hand dermatitis increases in parallel with the increase of clinical practice hours among nursing students. Familial and environmental factors also increase the risk of hand dermatitis.

Availability, Accessibility and Proper Use of Personal Protective Equipment in Wards at Queen Elizabeth Central Hospital (QECH) Blantyre, Malawi: An Observational Study.

Background: The purpose of this study was to evaluate the availability, accessibility and proper use of personal protective equipment (PPE) in the wards at Queen Elizabeth Central Hospital (QECH). Methods: We conducted an observational study with a cross-section design. Convenience sampling method was used for selection of healthcare workers (HCWs) in wards. HCWs filled a checklist on accessibility of PPEs and they were observed on proper use of PPE while conducting clinical procedures. Nurse ward in-charge was asked to fill out a checklist on availability of PPE in their ward. Results: PPE was available in 75.8% of wards, not available in 12.5%. Goggles were absent in 70.8% of wards. PPEs were 71.4% accessible and 28.6% inaccessible to healthcare workers in the wards. The most inaccessible PPEs were goggles (83.2%) and footwear (73.7%) while facemasks, sterile and non-sterile gloves and aprons were readily accessible. Non sterile gloves were 100% available and accessible. Only 13.5% of the HCWs had good compliance with PPE standard procedures. The average PPE compliance score of those who had been trained was 6 % greater than those who were not trained. Conclusion: This study identified areas of improvement in healthcare system delivery regarding standard precautions with emphasis on PPE. Improvements in training during professional college education and in-service refresher training could improve compliance with appropriate use of PPE for relatively low cost. Management support could improve availability and accessibility of PPE in the wards at QECH, with active supervision to improve adherence levels to personal protective equipment usage. The study can also help in the development of policies and guidelines regarding PPE usage by showing that most HCWs need to be trained in proper PPE usage.

A pilot survey of Southeastern firefighters: Safety practices, use of protective gear, and injury.

INTRO: There were over 60 firefighter line of duty deaths and roughly 30,000 injuries in the United States in 2016. Modern thermoprotective gear has reduced the risks firefighters face from both thermal and inhalation injury, but must be used properly to be effective. The purpose of this study is to examine gear use and associated injury in firefighters. METHODS: Surveys were distributed with questions about demographics, gear usage, and maintenance practices. If previously injured, firefighters described the injury, treatment, and recovery. RESULTS: Of the 50 surveys distributed, 37 were returned (72%). A majority of respondents (70%) reported wearing incomplete gear. Those who reported injury were more likely to have omitted gear (81% vs 45%). For all respondents, the items most commonly omitted were hood (58%), gloves (22%), and earflaps (22%). Regular cleaning of gear was not practiced by 39% of burned respondents and 46% had not had their gear sized within 2 years. Serious burns were reported by 41% of respondents. Mean burn size was 7% total body surface area (TBSA), and 11% reported self-treating their burns, including 63.5% who continued to work despite suffering a 2nd or 3rd degree burn injury. Only 17% were treated at a burn center, and this group missed anywhere from two shifts to 8 months of work. CONCLUSIONS: Firefighters risk injury by omitting gear and not adhering to National Fire Protection Association (NFPA) guidelines on gear sizing, maintenance, and station wear. Firefighters also frequently self-treat serious burns despite unique considerations regarding re-injury. National trends related to gear use and injury risk should be studied further, and standards should be developed for ensuring safe return to work.

Exposure of Agriculture Workers to Pesticides: The Effect of Heat on Protective Glove Performance and Skin Exposure to Dichlorvos.

Dichlorvos is a toxic organophosphate insecticide that is used in agriculture and other insecticide applications. Dermal uptake is a known exposure route for dichlorvos and chemical protective gloves are commonly utilized. Chemical handling and application may occur in a variety of thermal environments, and the rates of both chemical permeation through gloves and transdermal penetration may vary significantly with temperature. There has been no published research on the temperature-dependent kinetics of these processes for dichlorvos and thus, this study reports on the effects of hot conditions for the concentrated and application strength chemical. Dichlorvos breakthrough times for non-disposable polyvinyl chloride (PVC) gloves at 60 °C were approximately halved compared to 25 °C for the concentrate (2 vs. 4 h) and more than halved at application strength (3 vs. >8 h). From permeation experiments covering 15-60 °C, there was a 460-fold increase in cumulative permeation over 8 h for the concentrated dichlorvos and the estimated activation energy halved. Elevated temperature was also shown to be a significant factor for human skin penetration increasing the cumulative penetration of concentrate dichlorvos from 179 ± 37 to 1315 ± 362 µg/cm2 (p = 0.0032) and application strength from 29.8 ± 5.7 to 115 ± 19 µg/cm2 (p = 0.0131). This work illustrates the important role temperature plays in glove performance and health risk via dermal exposure. As such, it is important to consider in-use conditions of temperature when implementing chemical hygiene programs.

Skin reactions among Bulgarian dental students: A self-report questionnaire survey.

BACKGROUND: Dental students are at high risk of developing adverse skin reactions following practical work during the dentistry degree program. They encounter multiple irritants and allergens that may cause skin reactions on exposed parts of the body, notably the hands. OBJECTIVES: To estimate the prevalence of skin reactions related to the pre-clinical and clinical training courses of the dentistry program and associated risk factors in Bulgarian dental students. METHOD: A cross-sectional study was performed using a self-report questionnaire. RESULTS: A total of 467 dental students completed the questionnaire (response 51.8%). The prevalence of self-reported skin symptoms was 21.2%. According to logistic regression analysis, the most important risk factors for work-related skin symptoms were a personal history of atopic dermatitis (odds ratio [OR] 3.92, 95% confidence interval [CI]: 1.99-7.72), allergic rhinoconjunctivitis and/or asthma (OR 1.94, 95%CI: 1.03-3.68), personal history of contact allergy (OR 2.19, 95%CI: 1.06-4.55), and hand washing >16 times a day (OR 2.42, 95%CI: 1.06-5.52). CONCLUSIONS: The results of this study suggest that work-related skin symptoms are frequent among dental students and indicate the need to establish effective primary preventive programs for occupational skin disorders at a national level.

Association between universal gloving and healthcare-associated infections: A systematic literature review and meta-analysis.

OBJECTIVE: Healthcare-associated infections (HAIs) are a significant burden on healthcare facilities. Universal gloving is a horizontal intervention to prevent transmission of pathogens that cause HAI. In this meta-analysis, we aimed to identify whether implementation of universal gloving is associated with decreased incidence of HAI in clinical settings. METHODS: A systematic literature search was conducted to find all relevant publications using search terms for universal gloving and HAIs. Pooled incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were calculated using random effects models. Heterogeneity was evaluated using the Woolf test and the I2 test. RESULTS: In total, 8 studies were included. These studies were moderately to substantially heterogeneous (I2 = 59%) and had varied results. Stratified analyses showed a nonsignificant association between universal gloving and incidence of methicillin-resistant Staphylococcus aureus (MRSA; pooled IRR, 0.94; 95% CI, 0.79-1.11) and vancomycin-resistant enterococci (VRE; pooled IRR, 0.94; 95% CI, 0.69-1.28). Studies that implemented universal gloving alone showed a significant association with decreased incidence of HAI (IRR, 0.77; 95% CI, 0.67-0.89), but studies implementing universal gloving as part of intervention bundles showed no significant association with incidence of HAI (IRR, 0.95; 95% CI, 0.86-1.05). CONCLUSIONS: Universal gloving may be associated with a small protective effect against HAI. Despite limited data, universal gloving may be considered in high-risk settings, such as pediatric intensive care units. Further research should be performed to determine the effects of universal gloving on a broader range of pathogens, including gram-negative pathogens.

A job-exposure matrix addressing hand exposure to wet work.

PURPOSE: The aim of this study was to create a job-exposure matrix (JEM) for wet work. A JEM is a tool used to assess exposure to potential health hazards in occupational epidemiological studies. It can be used when counselling concerning job change/job choice, as a medico-legal tool when recognizing diseases as occupational and when planning interventions regarding prevention of, in this case, occupational hand eczema. METHODS: The study population was based on results from national surveys on working environment performed by the National Research Centre for the Working Environment in Denmark in 2000, 2005, and 2010 (National Research Centre for the Working Environment). We assessed responses on questions regarding wet hands, glove wear and total wet work. For the JEM a cutoff of 2 h total wet work/day was chosen as the exposure measurement. The proportion of responses of 2 h total wet work/day in each profession is illustrated as a number between 0 and 1 equal to 0-100% of the responses. RESULTS: Total wet work was most frequent among cleaners (domestic, office, and hotel cleaning), butchers and fishmongers, cooks, beauticians (hairdressers, barbers, related work) and health care workers (home-based personal workers, dentists, dental assistants). Regarding differences between sexes we found that indifferent of age and profession, women had 78% higher odds of having wet work. CONCLUSION: We found that wet work as an exposure varies among professions depending on whether wet hands or glove wear is assessed. A JEM is a useful tool to assess the extent of the exposure, wet work, independent of prior perceptions of classical wet work professions.

Reduction of Operator Hand Exposure in Interventional Radiology With a Novel Finger Sack Using Tungsten-containing Rubber.

The purpose of this study was to evaluate the x-ray shielding ability of a novel tungsten-particle-containing rubber-based finger sack for use in interventional radiology. Shielding rates for the air kerma (mGy m) were measured using a semiconductor dosimeter with and without the finger sack and commercial lead gloves, at a 20 cm distance from the field of view. A C-arm digital angiography system was used with x-ray tube voltages of 60, 80, 100, and 120 kVp. In addition, the 70 µm dose equivalent to the operator's finger was measured using fluorescent glass dosimeters with and without the finger sack during interventional radiology examinations. The x-ray shielding rates for 60, 80, 100, and 120 kV x rays were 98.0 ± 0.03%, 94.8 ± 0.05%, 92.3 ± 0.12%, and 90.1 ± 0.03%, respectively, with the finger sack and 69.8 ± 0.39%, 61.0 ± 0.53%, 52.3 ± 0.52%, and 47.0 ± 0.69% with the lead gloves. The x-ray shielding rates for the fluoroscopy and cine mode with the finger sack were 91.3 ± 0.21% and 56.5 ± 0.58%, respectively, while with the lead gloves they were 96.5 ± 0.04% and 67.6 ± 0.33%. The 70 µm dose equivalent for the operator's finger exposure dose was reduced by approximately 39.4% using the finger sack. The finger shields were more user friendly, had excellent radiation shielding ability against x rays, and should reduce finger exposure in interventional radiology.

Self-Reported Skin Disorders Among Health Care Workers.

This study aimed to estimate the point prevalence and 1-year period prevalence of skin disorder symptoms (SDS) among health care workers (HCWs) and to explore the possible risk factors. A random sample of 400 HCWs from 13 government health centers in Brunei Darussalam self-administered an adapted Nordic Occupational Skin Questionnaire (NOSQ-2002/SHORT). The point and 1-year prevalence of SDS were 12% and 19%, respectively. Having a history of SDS before the current job, exposure to SDS-exacerbating materials at the workplace, and having clinical roles were correlated for both prevalence estimates. Frequent handwashing and moderate use of latex gloves were associated with higher risk of SDS at 1-year. Female HCWs were more likely to report SDS. In multivariate analyses, only contact with SDS-exacerbating materials at the workplace, prejob SDS, and moderate glove usage were significant predictors of SDS.

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.
