Objective To observe the application effect of the H2H model in rehabilitation nursing for patients undergoing radical mastectomy.

Methods A total of 294 patients who underwent radical mastectomy were enrolled as study subjects and randomly divided into conventional group and H2H group using a simple randomization method (coin toss), with 147 patients in each group. The conventional group received routine nursing interventions, while the H2H group received nursing interventions based on the H2H model. At 1 week and 3 months post-intervention, shoulder joint functionassessed using the Constant-Murley Shoulder Function Score (CMS), nutritional indicators (serum albumin, hemoglobin) levels, self-management efficacyassessed using the Self-care Self-efficacy Scale (SUPPH), and quality of lifeassessed using the Functional Assessment of Cancer Therapy-Breast (FACT-B)were observed and compared between the two groups.

Results At 3 months post-intervention, the pain, daily living activities, range of motion, and muscle strength scores in the CMS were higher than those at 1 week post-intervention in both groups, with the H2H group showing higher scores than the conventional group, and the differences were statistically significant (P < 0.05). At 3 months post-intervention, the albumin and hemoglobin levels were lower than those at 1 week post-intervention in both groups, but the H2H group had higher levels than the conventional group, and the differences were statistically significant (P < 0.05). At 3 months post-intervention, the positive attitude, self-decision-making, and self-stress reduction scores in the SUPPH were higher than those at 1 week post-intervention in both groups, with the H2H group showing higher scores than the conventional group, and the differences were statistically significant (P < 0.05). At 3 months post-intervention, the scores for physical well-being, social/family well-being, emotional well-being, functional well-being, and the breast cancer-specific module in the FACT-B were higher than those at 1 week post-intervention in both groups, with the H2H group showing higher scores than the conventional group, and the differences were statistically significant (P < 0.05).

Conclusion The application of the H2H model in rehabilitation nursing for patients after radical mastectomy can promote the recovery of shoulder joint function, improve nutritional status, and enhance self-management efficacy and quality of life.
