Primary prevention in health care employees: a prospective intervention study with a 3-year training period.
Irritant contact dermatitis is a mayor problem in health care employees. Because educational programs have shown convincing success in certain occupations (e.g. in hairdressers), this study investigates the effect of a special training program in health care trainees. 521 trainees from 14 nursing schools in Central Germany were randomly divided in 2 groups, (i) an intervention group with a regular teaching protocol regarding all aspects of primary prevention and (ii) a control group without any further teaching. Morphological changes of the hands, use of hand care creams and knowledge regarding skin care were evaluated regularly during their 3 years lasting training period (1999-2002). In the intervention group, we found at the end of the 3-year training period a significant better skin condition of the hands than in the control group: a 3-year prevalence of morphological skin changes of 66.7% versus 89.3%. The unteached trainees (control group) had an odds ratio (OR) of 4.8 [95% confidential interval (CI): 2.9-7.8] for developing any skin changes on the hands after 3 years. Besides the effect of the teaching, the history of hand dermatitis before the study start was an independent risk factor for development of further hand dermatitis [OR 1.9, 95% CI: 1.0-3.6). Age and sex showed no influence on the skin condition. Atopic constitution had an influence on the development of skin changes only at the evaluation after 18 month. The observed effect in the intervention group may best be explained by different behaviour of the trainees, e.g. the amount of hand washing was reduced, while procedure of hand disinfection remained unchanged compared with the control group. However, the amount of used skin care cream did not differ between the both groups. This study shows that primary prevention of skin disease by regularly teaching during the training period of medical employees can effectively reduce the risk of development of irritant skin changes of the hands. Therefore, teaching and continuous motivation regarding preventive individual and collective measures during the training of medical staff should be an obliged part of the curriculum.
