Objective:To establish a standardized intervention system for chronic wounds and observe its clinical practice application effects.Methods:From January to December 2019, convenience sampling was used to select 150 patients with chronic wounds admitted to Room 1 of the Wound Treatment Center of the No.988 Hospital of the Chinese People's Liberation Army as the control group, and 145 patients with chronic wounds admitted to Room 2 of the Wound Treatment Center as the observation group. Control group conducted conventional wound intervention, and observation group implemented standardized wound intervention. The wound and pain of the two groups of patients were compared.Results:After the intervention, the wound temperature of observation group was higher than that of control group, and the pH value of exudate, pain score, and Bates-Jensen score were lower than those of control group, and the differences were statistically significant ( P<0.05) . The wound healing time of observation group was shorter than that of control group, and the hospitalization cost was less than that of control group, and the differences were statistically significant ( P<0.05) . Conclusions:The standardized intervention system for chronic wounds can effectively improve the treatment effect of chronic wounds, shorten wound healing time, reduce wound treatment costs and the burden on patients, medical care systems and society, and can provide scientific guidance and basis for the implementation, further research and development of clinical wound care.
