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.
