[The moderating effect analysis of mindfulness on perceived stress and job burnout of medical staff].

Objective: To explore the moderating mechanism of mindfulness on perceived stress and job burnout of medical staff. Methods: From November 2020 to March 2022, 1626 medical staff were investigated by questionnaires. Chinese Version Perceived Stress Scale (CPSS), Maslach Burnout Inventory-Human Service Survey (MBI-HSS) and Mindful Attention Awareness Scale (MAAS) were used to evaluate the perceived stress, three dimensions of job burnout[depersonalization (DP), emotional exhaustion (EE), personal accomplishment (PA) ], and mindfulness level of medical staff. The Spearman rank correlation analysis was used to analyze the correlation between mindfulness and perceived stress, job burnout of medical staff. And the SPSS PROCESS macro program was used to test the moderating effect of mindfulness on perceived stress and job burnout. Results: Among the 1626 medical staff, 57.38% had perceived stress with health risk (933/1626), and 63.84% (1038/1626) had job burnout, among them, with 618 (38.01%), 274 (16.85%), and 146 (8.98%) experiencing mild, moderate and severe job burnout, respectively. The scores of mindfulness among medical staff were significantly correlated with perceived stress and various dimensions of job burnout (EE, DP and PA) (r(s)=-0.155, -0.351, -0.315, 0.307, P<0.001). Mindfulness had a moderating effect between perceived stress and job burnout, which was achieved through three moderating pathways: perceived stress-mindfulness-EE, perceived stress-mindfulness-DP and perceived stress-mindfulness-PA (ΔR(2)=0.073, 0.06, 0.006, P<0.001) . Conclusion: Medical staff have a high level of job burnout, mindfulness plays a moderating role between perceived stress and job burnout. Specific measures can be taken to improve the level of mindfulness in medical staff, so as to prevent and alleviate job burnout of medical staff.

Early vascular grafting to prevent upper extremity necrosis after electrical burns.

Presented in this paper are the surgical considerations in the management of 8 electrically injured patients, with special reference to the care for wrist damage associated with impaired blood flow, and the prospect for effective recovery. Sound surgical principles, such as early diagnosis and repair of artery damage, complete débridement of dead tissue and affective wound closure, in conjunction with intensive general treatment and overall planning, are necessary for maximally rehabilitated limbs. The electrically injured seem to have benefited a great deal from the procedures outlined, with a lowered incidence of amputation and a better functional recovery.
