Application effects of the TTM intervention of stage 3-4 pressure ulcer for pressure ulcer awareness changes of primary caregivers in the care behavior of pressure ulcer patients

ObjectiveTo explore the application effects of the trans-theoretical model of change(TTM) intervention of stage 3-4 pressure ulcer for pressure ulcer awareness changes of primary caregivers in the care behavior of pressure ulcer patients.

MethodsFifty-six primary caregivers of patients with stage 3-4 pressure ulcer from July 2018 to January 2020 were selected as the research objects.Twenty-eight primary caregivers of patients with stage 3-4 pressure ulcer from July 2018 to March 2019 were set as the control group, and 28 primary caregivers of patients with stage 3-4 pressure ulcer from April 2019 to January 2020 were set as the intervention group.The cognition, care behavior, recurrence rate and healing time of pressure ulcer before TTM intervention and after 6 months of TTM intervention were compared between two groups.

ResultsBefore intervention, the total cognitive score, knowledge related to pressure ulcer, perceived severity and susceptibility score of pressure ulcer in intervention group were significantly higher than those in control group(P < 0.01).Except for the dimensions of knowledge related to pressure ulcer and perceived susceptibility in control group, the scores of the other dimensions increased compared with before intervention, and the increasing of which in the intervention group was more obvious(P < 0.01).The total score of care behavior, turn over behavior, skin care, nutritional support and wound care scores in intervention group after intervention were higher than those in control group(P < 0.01).Except for the dimensions of skin care and nutritional support in control group after intervention, the scores of other dimensions increased compared with before intervention, and the increasing of which in the intervention group was more obvious(P < 0.01).The recurrence rate of pressure ulcer and wound healing time in intervention group were significantly less than those in control group(P < 0.01).

ConclusionsTTM can effectively change the awareness of the primary caregivers of pressure ulcer, improve the care behavior of pressure ulcer, reduce the recurrence rate of pressure ulcer and shorten the wound healing time, which is worthy of promotion.
