Short-term effect of dressing with Dermaheal ointment in the treatment of diabetic foot ulcer: A double-blinded randomized controlled clinical trial

Background and Aims

Diabetic foot ulcers, a major cause of amputations in diabetics, could benefit from natural products as adjuncts to standard care, given the costs and adverse effects of typical therapies. This study aims to evaluate the short-term effects of dressing with Dermaheal ointment in the treatment of DFUs through a double-blinded randomized controlled clinical trial.

Methods

This double-blinded, placebo-controlled trial included 50 patients with Wagner's ulcer grade I or II, randomly assigned to Dermaheal and placebo groups (received standard treatment and placebo ointment). The ulcer site was dressed daily for four consecutive weeks with either Dermaheal or placebo ointment. Ulcer healing score (using DFU healing checklist), ulcer size with transparent ruler and largest dimension of ulcer, and pain severity using numerical pain rating score (were recorded at five-time points, including baseline, and on weeks 1, 2, 3, and 4). Also, ulcer healing status was investigated at the trial ended in November 2021.

Results

Both groups showed significant improvement in ulcer healing over 4 weeks (p time < 0.001), with more remarkable progress in the Dermaheal group (p group = 0.03). At the trial end, complete ulcer healing was also significantly higher in the Dermaheal group compared to the placebo group (56% vs. 12%, p = 0.002). Both groups exhibited a decrease in ulcer size (p time < 0.001). Considering the baseline ulcer size as a covariate, substantial changes in mean ulcer size were noted in the initial (p = 0.01), second (p = 0.001), third (p = 0.002), and fourth (p = 0.002) weeks of the intervention, showing a preference for the Dermaheal group. However, no significant between-group difference was observed in pain severity levels.

Conclusion

Dressing with Dermaheal as a topical treatment shows promise in improving healing and reducing the size of diabetic foot ulcers. Further research is needed to confirm these findings' long-term efficacy.

Effectiveness of continuous home wound care on patients with diabetic foot ulcers

AIMS

To explore the effectiveness of continuous home wound care on patients with diabetic foot ulcers (DFUs).

DESIGN

A non-randomized parallel controlled non-inferiority trial.

METHODS

Patients with Wagner grade I-III DFUs hospitalized in two distant campuses of the same hospital were included. All patients received infection treatment and wound bed preparation during hospitalization; after discharge, patients in one of the campuses received routine outpatient wound care, and those treated in the other received continuous home wound care. The per-protocol analysis was performed to compare ulcer healing indicators, knowledge, health belief, self-management behaviour and medical expenses of the two groups.

RESULTS

Between October 2021 and December 2022, 116 patients were enrolled in the study; 107 completed. The home care was not inferior in terms of ulcer healing rate and demonstrated significant enhancements in the understanding of warning signs, health belief and self-management behaviour. Additionally, the home care saved 220.38 yuan (24.32 UK pounds) in direct medical expenses for each additional one square centimetre of ulcer healing.

CONCLUSION

The continuous home wound care enhanced self-management behaviour of the patients and saved their medical expenses while not compromising ulcer healing.

IMPACT

This is to date the first study to conduct continuous home wound care practice for patients with DFUs and confirmed its safety and non-inferiority in ulcer healing, and supported its superiority in improving self-management behaviour and saving medical expenses.

REPORTING METHOD

We have adhered to the transparent reporting of evaluations with nonrandomized designs statements and the corresponding checklist was followed.

PATIENT OR PUBLIC CONTRIBUTION

The patients and their primary caregivers were involved in intervention design, we received input from them about the factors that facilitate and hinder patient self-management behaviours to develop intervention strategies.
