RESUMEN
Objective: To investigate the effect of the intervention program based on the Interaction Model of Client Health Behavior (IMCHB) in patients with pressure injury (PI). Methods: The First Affiliated Hospital of Qiqihar Medical University received thirty patients suspected of having pressure injuries from June to December 2022. These patients were selected as the control group. Another thirty patients suspected of having pressure injuries were received by the hospital from January to June 2023 and were selected as the experimental group. The experimental group received a usual care protocol, while the trial group received the IMCHB model intervention for three months. The study compared the knowledge of pressure injuries, quality of life, incidence of pressure injuries, and patient satisfaction of high-risk patients between the two groups. Results: After the intervention, the PI awareness score of caregivers in the experimental group was (31.90 ± 5.24). It is higher than the control group (26.37 ± 6.85). The point of social function, physical function and material function of experimental group were (57.03 ± 5.32), (33.47 ± 3.52) and (58.53 ± 6.93). Respectively, it was higher than the experimental group (48.63 ± 4.80), (27.17 ± 3.04), (46.13 ± 6.72). The incidence of high-risk PI in the experimental group was 3.33%. The point of the control group was 26.67%. The total satisfaction of the experimental group was (8.27 ± 0.78) points, higher than the control group (7.30 ± 0.65). The difference was of statistical significance (P < .05). Conclusion: The intervention program based on IMCHB can significantly improve cognitive ability and thus promote health behavior.
