Background Apprentice nurses are considered at high risk to developing occupational skin diseases. Objectives This study assessed the frequency and origin of hand eczema, and work‐related risk factors in apprentice nurses. Methods The study involved 240 final‐year apprentice nurses (females 75%, median age 19 years) from vocational schools in Zagreb, Croatia. The study was performed in 2020/2021 and included a questionnaire and clinical examination by means of the Osnabrück Hand Eczema Severity Index (OHSI). Skin prick test (SPT) with natural rubber latex (NRL) allergen, and patch test with the basic series of allergens, and disinfectants, were performed in 42 apprentice nurses with hand eczema that lasted more than 3 months. Results Clinically observed and self‐reported hand eczema were found in 49% and 46% of apprentice nurses, respectively. Those with observed changes were older and reported more days per month spent on practical work than those with healthy skin ( P = .001). Median OHSI was 4 (interquartile range 2‐6). There were no positive SPTs to latex, and 11 (26%) apprentice nurses had positive patch test reactions to one or more tested allergens, mostly nickel. Conclusions Hand eczema was common in final‐year apprentice nurses during the COVID‐19 pandemic. It was mostly of irritative origin, associated with the duration of practical training, confirming cumulative effect of hazards on skin barrier.

Background: Studies investigating simultaneous influence of personal and workrelated factors on skin health during the coronavirus disease 2019 (COVID-19) pandemic are missing.Objectives: To investigate the associations of skin hazards relevant for nursing apprentices with parameters of skin barrier function.Methods: A total of 238 nursing apprentices attending the final year of education (median age 19 years) from vocational schools in Zagreb, Croatia, were enrolled in this study. We administered a questionnaire based on the Nordic Occupational Skin Questionnaire to the nursing apprentices, performed clinical examination of skin on the hands, and evaluated transepidermal water loss (TEWL) and stratum corneum (SC) pH on the dorsum of the hand.Results: Around half of nursing apprentices had compromised hand skin barrier function, as indicated by TEWL values >25 g/m 2 /h (48%) and SC pH >5.5 (57%). Skin barrier was compromised in around 40% of nursing apprentices without clinically observed skin symptoms. Elevated SC pH was independent of ambient conditions associated with skin symptoms and female sex.Conclusions: Measurement of SC pH was shown to be less sensitive to field conditions than TEWL, and should be employed more in the field studies. Strengthening of skin health promotion in healthcare workers and apprentices is needed in pandemic conditions.
