Participant Flow

61 patients were screened for eligibility between May 2018 and December 2019 at the Dermatology department at University Hospital in Linköping, Sweden and 2 of these patients were enrolled. 3 patients were screented for eligibiity and enrolled between July 2019 and December 2019 at S2Clinic in Linköping, Sweden.

Each enrolled participant used both investigational device Variant A and Variant B in either the order A-B-A or B-A-B according to a pre-designed schedule to ensure equal numbers in the two study arms. All 5 enrolled participants completed the study.

Measure
A-B-A
Investigational device is Absorbest moisture sensor in variant A and variant B, placed on the backside of the wound dressing DryMax Extra Soft. Participants performed three dressing changes. They first received variant A, at next dressing change they received variant B, and on the third dressing change they received variant A again. No washout periods
B-A-B
Investigational device is Absorbest moisture sensor in variant A and variant B, placed on the backside of the wound dressing DryMax Extra Soft. Participants performed three dressing changes. They first received variant B, at next dressing change they received variant A, and on the third dressing change they received variant B again. No washout periods

PRIMARY outcome

Timeframe: Inclusion visit to study completed after 3 dressing changes, 1-2 weeks

Population: All patients recieved three dressing changes and were included in the analysis.

Dressing weight after use were measured on a scale and recorded. The weight were compared to a predefined table. Dressing size 10x10 cm: Changed too early \<11 g Correct change 11-26 g Changed too late \>26 g Dressing size 10x20 cm: Changed too early \<17 g Correct change 17-62 g Changed too late \>62 g Dressing size 20x20 cm: Changed too early \<26 g Correct change 26-109 g Changed too late \>109 g
