Background: Pressure injuries present a significant challenge for patients receiving home care, particularly those with limited mobility. Although l-arginine supplementation has shown promise for wound healing, the optimal dosage remains unclear. This study compared the effectiveness of two daily l-arginine doses (7 g versus 14 g) in treating pressure injuries over a six-month period. Methods: We retrospectively reviewed the medical records of 120 adult patients with grade 3 or 4 pressure injuries who received home care between June and December 2023. Patient wounds were evaluated using the DESIGN-R assessment tool, which measures various aspects of wound healing. Statistical analysis was performed using SPSS 26.0, employing generalized estimating equations (GEE) to account for repeated measurements over time. Results: The study found that patients receiving the 7 g daily l-arginine dose showed significantly better wound healing after 1 month compared to those receiving 14 g (p < 0.001). While healing rates varied throughout the study period, the 7 g dose consistently demonstrated superior outcomes by the six-month mark (p < 0.05). Notably, the higher 14 g dose did not provide additional healing benefits at any point during the study. Conclusion: Our findings indicate that a daily 7 g l-arginine supplement effectively promotes both early- and late-stage healing of pressure injuries in home-care patients. This lower dose not only matches or exceeds the healing outcomes of the higher dose, but also presents a more cost-effective treatment option. Healthcare providers may consider implementing a 7 g dosage as a standard protocol for pressure injury treatment in home care settings. ; Full Text |
