To study the clinical effect of psychiatric nursing-based vancomycin in patients with staphylococcus aureus infectious skin disease. A retrospective analysis was performed on 100 patients with staphylococcus aureus infectious skin disease admitted to our hospital from March 2019 to July 2020. Al patients received psychiatric nursing and were divided into control group (mupiroxine) and experimental group (vancomycin) according to the treatment mode, with 50 patients in each group. The effective rate of treatment, adverse reactions, disappearance time of dermatological clinical symptoms and recurrence after one course of treatment were compared between the two groups. The effective rate of the experimental group was significantly higher than that of the control group (P<0.05).The incidence of adverse reactions and the disappearance time of clinical symptoms in the experimental group were significantly lower than those in the control group (P<0.05). After one course of treatment, the number of patients with recurrence in the experimental group was significantly lower than that in the control group (P<0.05). Vancomycin might be a boon for patients with staphylococcus aureus infectious skin diseases, with good effectiveness and safety profiles.
