Study Description

Brief Summary:

Residents of institutional long-term care facilities are at high risk for developing skin and tissue diseases, e.g. xerosis cutis (including pruritus), infections (e.g., tinea pedis, candidiasis), chronic wounds or neoplastic changes (e.g. actinic keratosis, malignant melanoma) but there are few epidemiological figures about the actual frequencies of these conditions in nursing homes. Therefore, in the first part of this study we aim at measuring key dermatological conditions and associated health and functional status, and the skin care practice of aged nursing home residents ("prevalence study").

Basic skin care interventions are believed to reduce skin dryness and to enhance skin health. Thus, the second aim of this study is to investigate the effectiveness of two structured skin care regimens compared to the routine standard skin care on skin health in nursing home residents ("intervention study").

The study will be conducted in a random sample of seven out of approximately 300 institutional long term care facilities of the federal state of Berlin.

Outcome Measures

Primary Outcome Measures :

1. Change From Baseline in Overall Dry Skin Score (ODS) [ Time Frame: Baseline; Day 56+/-4 ]
   Clinical assessment of the presence or severity of skin dryness using a five point rating scale at right lower leg. The Overall Dry Skin score is a clinical assessment of the presence and severity of skin dryness using a five-point scale. A score of '0' indicates no skin dryness, whereas a score of '4' indicates advanced skin roughness, large scales, inflammation and cracks.

Secondary Outcome Measures :

1. Stratum Corneum Hydration (SCH) [ Time Frame: Baseline, Day 56 +/- 4 ]
   Change in Stratum corneum hydration (SCH) at the lower leg. Instrumental skin measurements were conducted to characterize possible effects of the interventions in terms of skin function. The stratum corneum hydration was measured using the Corneometer CM 825 (Courage + Khazaka, Cologne, Germany). This measurement is based on the differences of the dielectric constant of water and other substances. With this device, only the moisture content in the stratum corneum is measured. The arbitrary units (a.u.) range from 0 to 120 where as higher readings indicate higher stratum corneum hydration.Values > 40 a.u. are often considered 'normal', whereas values < 40 a.u. are regarded as typical for dry Skin.
2. Transepidermal Water Loss (TEWL) [ Time Frame: Baseline, Day 56 +/- 4 ]
   Change in Transepidermal water loss (TEWL) at the lower leg. Transepidermal water loss was measured with the Tewameter TM 300 (Courage + Khazaka, Cologne, Germany). The probe captures the constant permeation of water through the stratum corneum in gram per hour per m2. The measuring probe contains a pair of sensors that are located in different distances to the skin surface to determine temperature and relative humidity above the skin surface. The humidity gradient between both sensors is used for calculating the transepidermal water loss. Higher values indicate a higher transepidermal water loss.
3. Skin Surface pH [ Time Frame: Baseline, Day 56 +/- 4 ]
   Changes in Skin surface pH at the lower leg. Skin surface pH was measured with the Skin-pH-Meter PH 905 (Courage + Khazaka, Cologne, Germany), a planar glass electrode. The pH is a measure of acidity and alkalinity of a solution and it indicates the concentration of the hydrogen ions in an aqueous solution. Reference values of human skin have been reported to range from 4 to 6.
4. Itch Assessment. Question 1. Hours of Itching (1 = Less Than 6 Hours/Day; 2 = 6-12 Hours/Day; 3 = 12-18 Hours/Day; 4 = 18-23hours/Day; 5 = All Day) at Baseline [ Time Frame: Baseline ]

   Self-completion of the 5-D itch scale. Having a 6-CIT score of 7 or lower was the criterion to administer the 5-D itch scale.The score of the 5-D Itch scale ranges from '5' (no pruritus) to '25' (most severe pruritus) and contains five items measuring pruritus over the past two weeks.

   A possible cognitive impairment was tested using the Six Item Cognitive Impairment Test on Day 0. It includes six simple questions, for example 'What year is it?' or 'Count backwards from 20 to 10. Scores may range from 0 (= no sign of cognitive impairment) to a maximum score of 28 (= significant cognitive impairment). Residents with sum scores > 8 were classified as 'cognitively impaired'.
