Efficacy of Stamp Skin Grafting to Promote the Healing Process of Chronic Wounds.

Objective: To investigate the clinical efficacy of stamp skin grafting in promoting wound healing for patients with chronic wounds.

Methods: This study enrolled 86 patients with chronic wounds from a wound care clinic between November 2022 and December 2023. The participants were randomly allocated into the control (n = 44) and skin-grafting (n = 42) groups using a preset random number table. The control group received conventional wet dressing care, whereas the skin-grafting group underwent additional stamp skin-grafting care.

Results: The skin-grafting group demonstrated significantly reduced wound healing time, improved healing efficacy, decreased dressing change frequency, and lowered dressing change costs compared with the control group (all Ps < .05). During the nursing process, the skin-grafting group exhibited significantly lower pretreatment Numeric Rating Scale scores when the fourth and fifth dressings were changed and during-treatment Visual Analog Scale scores from the third to fifth dressing changes compared with the control group (all Ps < .05). After adjusting for confounding factors, wound area served as an independent risk factor for both healing time (rpartial = 0.457, P < .05) and healing efficacy (β = -0.559, P < .05) in the skin-grafting group, whereas patient adherence to wound care served as an independent risk factor for both healing time (rpartial = 0.333, P < .05) and healing efficacy (β = 1.194, P < .05) in the control group, as well as for healing efficacy (β = 1.318, P < .05) in the skin-grafting group.

Conclusions: Stamp skin grafting effectively promotes the rapid recovery of chronic wounds with reduced medical burden and patient pain. The effectiveness primarily depends on the wound area and patient adherence.
