Objective? To investigate the effectiveness of family-based telenursing on the management of pressure sores in discharged emergency patients with pressure sores. Methods? Using the convenient sampling method, we selected 100 dyads of pressure sores patients along with their main home caregiver (one caregiver per patient). The patients were admitted to the Emergency Department of Beijing Anzhen Hospital from January to December 2017, who were randomly divided into the observation group and control group (50 dyads for each group). After the discharge of the control group, routine follow-ups were administered to guide the care of pressure sores. After the discharge of the observation group, the family-based telenursing was implemented for pressure sore management. The differences between the two groups of patients at the time of discharge, 2 months after discharge, nursing knowledge of pressure sore disease, differences in home care ability, and satisfaction with pressure sores management were analyzed. Results? There were no significant differences between the two groups at the time of discharge (P＞ 0.05). After 2 months of discharge, the severity of pressure sores, risk score, and recurrence rate of pressure sores in the observation group were lower than those in the control group, and the differences were statistically significant (P＜ 0.05). The caregiver's knowledge of pressure sores in the observation group was better than the control group, and the difference was statistically significant (P＜0.05). The total scores and the dimension scores of the family nursing evaluation in the observation group were higher than those in the control group, and the differences were statistically significant (P＜0.05). Patients and caregivers in the observation group were more satisfied with the nursing methods than the control group (P＜0.05). Conclusions? Family-based telenursing can improve the knowledge of pressure sores, the nursing ability,and effectively manage pressure sores.
