Objective To investigate the cost-effect of tele-wound treatment platform with cellular phone terminator and traditional outpatient treatment on chronic lower limb ulcers in remote district.Methods Thirty seven cases with chronic lower limb ulcers from the key hospitals in the district of west Hunan Province were collected by cluster sampling,and randomly divided into the intervention group (25 cases)and the control group (12 cases).They chose remote wound treatment platform intervention with cellular phone terminator and traditional dressing change in clinic.All patients received a 1.5-year follow-up,or cure and amputations were set as the endpoint of the study.The cost-effect,including the incidence of complications in the course of treatment,number of switches,treatment time,the cost of treatment,as well as medical human resources consumption was analyzed and compared between the two groups.Results The incidence of complications in the course of treatment in the intervention was (76.0％) significantly lower than the control group(91.7％).There was a significant increase in the dressing times and the duration of treatment; and there was no significant difference in the cost of treatment and medical human resources consumption between two groups.Conclusions Compared to the traditional outpatients wound treatment,the multimedia message-based tele-wound treatment platform unlikely increased medical human resources consumption and the cost of treatment,and may reduce the incidence of complications and the treatment time.
