Background:
Working in healthcare is regarded as a risk factor for occupational skin disease. Workers are exposed to disinfectants, soaps, detergents and latex and need to wash their hands frequently and thoroughly.
Aims:
To investigate the association between healthcare work and patch test reactions to various potential sensitizers in a population of contact dermatitis patients in various dermatology and occupational medicine units in north-eastern Italy.
Methods:
Patients with suspected allergic dermatitis underwent patch testing. Odds ratios (ORs) and 95% confidence intervals (CIs), adjusted by age and sex, were calculated for healthcare workers (HCWs), using white-collar workers as control group.
Results:
HCWs represented 14% of the sample of 19088 patients (68% women, 32% men). Among HCWs, both sexes had a higher risk of developing hand/forearm dermatitis (females: OR 2.1, 95% CI 1.8-2.5; males: OR 1.6, 95% CI 1.3-2.1). HCWs had an increased risk of sensitization to formaldehyde (OR 1.65; 95% CI 1.2-2.3) and to p-phenylenediamine (OR 1.6; CI 1.1-2.3).
Conclusions:
Our study suggests a significant association between healthcare work, hand/forearm dermatitis and sensitization to formaldehyde and p-phenylenediamine.
