Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Adherent Area Measured by Photo of Used Tape | Tapestrips per test product were removed from the baseplate at each product change and saved for the next site visit every 7-9 days for evaluation | The adherent area (cm2) measured per baseplate change after use shows how effectively the ostomy tape adheres to the skin. After removal of the ostomy tape, a photo of the tape was taken. The adherent area was measured from the photo and an image analysing program. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Erythema Measured After Each Treatment Period by Spectrophotometric Method | The measurements were carried out after 7-9 days of treatment with the test tape | A change in the surface skin colour is known to be related to a change in the blood flow. This can be measured non-invasively with a spectrophotometric instrument (Derma-spectrophotometer, Cortex Technology A/S, Hadsund) where redness of the skin is measured. The measurement of erythema is based on an active color detecting chip. Illumination is provided by two high intensity white LEDs. The spectrophotometer accommodates the color sensor, filters, optics and light source. Light is provided by two high intensity with LEDs and a unique feature is the guiding light, which illuminates the target during the positioning of the device. The LEDs illuminates the target area and the skin color measurement is performed. The measurements performed with the spectrophotometric instrument do not have units. But the measures are used for the estimation of the level of the redness (hemoglobin) in the skin. The higher the value, the more pigment in the skin. |
| Erythema Measured After Tape Removal by Photos | The measurements were carried out after 7-9 days of treatment with the test tape | A change in the surface skin colour is known to be related to a change in the blood flow. This can be measured non-invasively with a spectrophotometric instrument (Derma-spectrophotometer, Cortex Technology A/S, Hadsund) where both the redness and the colour of the skin are measured. Furthermore, visual assessments of photos have been used in several exploratory clinical investigations by Coloplast A/S to explore how adhesives affect the skin. The visual assessment is conducted by trained personnel and is a valuable tool for assessing newly developed adhesives and their impact on skin in the early development phases. |
| Feeling of Security | The evaluation was carried out after 7-9 days of treatment with the test tape | Subjects will be asked how they rate feeling of security (How was the feeling of security?) on a five point scale, when wearing the tape; 1. Very Poor, 2. Poor, 3. Acceptable, 4. Good, 5. Very Good. |
| Adhesion of Tape | The evaluation was carried out after 7-9 days of treatment with the test tape | Subjects will be asked how they perceive the immediate adhesion to the skin (how was the immediate adhesion to the skin?) and rate adhesion on a five-point scale: 1. Very poor, 2. Poor, 3. Acceptable, 4. Good, 5. Very good. |
| Skin Issues in the Area Covered by the Tape | The evaluation was carried out after 7-9 days of treatment with the test tape | Subjects will be asked if they had any skin-related complications in the area covered by the tape (yes, no). |
| Adverse Events | 27 days | All Adverse Events are captured and documented throughout the study. |
| Comfort | The evaluation was carried out after 7-9 days of treatment with the test tape | Subjects will be asked how they perceived the comfort of the tape (How comfortable was the tape to wear?) and rate comfort on a 5-pont scale; 1. very discomfortable, 2. Discomfortable, 3. Acceptable, 4. Comfortable, 5. Very comfortable. |

Erythema Measured After Each Treatment Period by Spectrophotometric Method
A change in the surface skin colour is known to be related to a change in the blood flow. This can be measured non-invasively with a spectrophotometric instrument (Derma-spectrophotometer, Cortex Technology A/S, Hadsund) where redness of the skin is measured. The measurement of erythema is based on an active color detecting chip. Illumination is provided by two high intensity white LEDs. The spectrophotometer accommodates the color sensor, filters, optics and light source. Light is provided by two high intensity with LEDs and a unique feature is the guiding light, which illuminates the target during the positioning of the device. The LEDs illuminates the target area and the skin color measurement is performed. The measurements performed with the spectrophotometric instrument do not have units. But the measures are used for the estimation of the level of the redness (hemoglobin) in the skin. The higher the value, the more pigment in the skin.
