The Effectiveness and Safety of Niacinamide 4% and Virgin Coconut Oil 30% for Secondary Prevention of Occupational Hand Dermatitis

Study Overview
=================
Brief Summary
-----------------
Occupational hand dermatitis (OHD) often occurs in intensive care unit (ICU) nurses, especially in individuals who are vulnerable due to irritant exposure e.g. hand rub alcohol and repeated hand washing activities. The use of moisturizer is one of the recommendations for skin care in OHD. Niacinamide which has anti-inflammatory effects and can improve the skin barrier function. Virgin coconut oil (VCO) is rich in lipids and lauric acid, and has an occlusive effect. Until now there are no guidelines and reference types of moisturizers for secondary prevention in DTAK.

Detailed Description
-----------------
The aim of this study is identify the effectiveness and safety between moisturizing cream containing niacinamide 4% and VCO 30% for secondary prevention of occupational hand dermatitis in ICU nurses This study also measured HECSI , TEWL, and SCap before and after treatment

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| HECSI | Hand eczema severity index (HECSI) is a score to indicate the severity of hand dermatitis. The range of HECSI score is 0-360. The HECSI score before treatment was expected to be higher than after treatment. Outcome: change of HECSI | 14 days |

| TEWL | Trans Epidermal Waterloss (TEWL) is the primary parameter which measured for the skin barrier function, when the skin barrier is damaged the skin will be disrupted in maintaining water. Passive water diffusion via the Corneal stratum. TEWL is measured in g/h/m2. The TEWL value before treatment was expected to be higher than after treatment. Outcome: change of TEWL | 14 days |

| SCap | Skin Capasitance (SCap) is a score for skin hidration. SCap can be done with measuring the water level in corneal stratum using non-invasive electric method which measure the capacitance. SCap is measured in Arbitrary Unit (AU). SCap value before treatment was expected to be lower than after treatment. Outcome: change of SCap | 14 days |
