BACKGROUND: Healthcare workers (HCWs) wash their hands with tap water (TW) and soap. However, hard TW causes dermatitis.
OBJECTIVES: The present study aimed to compare the effects of ultra-pure soft water (UPSW) with those of TW on the hands of HWCs.
METHODS: The present study was a prospective randomized trial with a crossover design. All the nurses in the neonatal intensive care unit (NICU) at the study centre were divided into Sequence 1 (UPSW to TW) or 2 (TW to UPSW) and washed their hands with TW or UPSW in alternating 4-week periods with a 4-week washout period. Trans-epidermal water loss (TEWL) and stratum corneum hydration (SCH) were evaluated. Skin condition was self-assessed.
RESULTS: Twenty-one and 22 nurses were assigned to Sequence 1 and Sequence 2, respectively. USPW increased SCH to a significantly greater degree than TW (mean: 26.3 μS ± 12.3 SD; 95% confidence interval: 1.12-51.54; p = 0.041) although it did not affect TEWL. UPSW use significantly improved the subjects' skin condition, as reflected in an overall increase in the assessment scores.
CONCLUSIONS: UPSW improved SCH and the condition of hand skin. Prolonged USPW use may increase nurses' comfort during work and hand hygiene compliance.
