The purpose of this study is to evaluate the performance and safety of Connettivina Bio, when used in the management of wounds. Moreover, the study will evaluate the correlation of the 'dressing system' (formed by the Connettivina Bio primary dressing plus a secondary one) used in different care settings. The study will include Italian healthcare facilities.

The primary objective of the prospective, multicentric, post-market clinical investigation is to evaluate the performance of Connettivina Bio (cream, gauze-pads) in the amelioration of wound bed appearance after 14 days of treatment. This objective will be assessed by measuring the percentage of patients showing, from baseline to 14 days of treatment, positive change in at least one of the following parameters: amelioration of wound tissue type (4=necrotic, 3=slough, 2=granulation tissue, 1=epithelial tissue, 0=closed), decrease of exudate amount (1=dry, 2=moist,3= slightly exuding, 4=heavily exuding, 5=wet) and amelioration of exudate type (1=bloody, 2=bloody/purulent, 3=clear, 4=murky,5= purulent, 6=serous). Furthermore, the secondary objectives of this clinical investigation include to define the Investigator's choice in clinical practice of Connettivina Bio (cream, gauze-pad) related to the clinical wound characteristics, the type of secondary dressing applied on the wound and the wound etiology, for this reason a descriptive analysis will be performed at baseline. Additionally, for the secondary objectives, the performance of Connettivina Bio (cream, gauze-pads) will be evaluated from baseline to 7, 21, 28, 42 and 56 days as amelioration of wound bed appearance in terms of type of wound bed tissue and exudate quantity and quality. To evaluate the improvement of quality of life of patients treated, the latter will be evaluated as a change from baseline to 56 days after the start of treatment, through administration of EuroQoL-5D (EQ-5D). Moreover, to evaluate the easiness of Connettivina Bio (cream, gauze-pads) application, the latter will be appraised by the clinician and by the patient after 56 days from the start of treatment as excellent, good, acceptable, bad or unacceptable. Finally, the safety and tolerability of Connettivina Bio (cream, gauze-pads) will be assessed throughout all the visits by investigating local and expected adverse events, as consequence of the product application and any other adverse event occurred during the study.
