Background Electric stimulation (E-stim) has been found to be an effective treatment in improving wound healing rates. However, the wound healing trajectory and its related predictors for complete wound closure (CWC) have not been reported with E-stim treatment. Materials and methods This was a retrospective study. Data on 159 patients treated at an outpatient wound clinic utilizing combined intervention of E-stim and conventional care were included. The Kaplan–Meier healing curve together with linear regression models depicted the percentage of patients with CWC against time. Results With 100, 112 and 140 days of treatment, the percentages of patients with CWC were 59·12%, 61·01% and 65·41%, respectively. Linear regression models predicted that all patients would achieve CWC by 21·55, 22·26 and 24·80 weeks, respectively. The speed for the increase in the number and percentage of patients with CWC peaked between 50–75 days of treatment. To optimize timely healing, referral to other treatment facilities or change of treatment protocol is warranted around the peak time. With the combined intervention of E-stim and conventional care, positive predictors for CWC included a shorter wound duration at initial evaluation (P = 0·005, OR = 3·10), better compliance with appointments (P = 0·007, OR = 3·38) and the diagnosis of venous leg ulcer (P = 0·001, OR = 3·88). Conclusions This study provided preliminary data on wound healing trajectory and predictors with combined E-stim and conventional care. E-stim seemed to expedite wound healing; however, further research studies are needed.
