[Investigation and analysis of the status of blood-borne occupational exposure of medical staff in a top three hospital and intervention measures].

To understand the current situation of blood-borne occupational exposure among health care workers and evaluate the intervention effect of PDCA. Retrospective survey was adopted to investigate and analyze the blood-borne occupational exposure incidents in a hospital from January 2015 to December 2018, and to compare the intervention effects after PDCA management. A total of 82 cases of occupational exposure occurred from 2015 to 2017, and only 9 cases happened after the implementation of PDCA intervention. The exposed population was mainly consisted of nurses (59 cases, 64.83%) , and mainly with low-working age (1-5 years) (56 cases, 61.54%) , and the main source of exposure was hepatitis B (34 cases, 37.36%) . In addition, after the implementation of PDCA, the vaccination rate of personnel was 77.78%, the standardized field treatment rate was 100%, the preventive drug use rate was 88.89%; The qualified rate of occupational protection assessment was higher than that before intervention, which all shows the difference was statistically significant (<0.05) . With the guide of PDCA management, Strengthen the training of new employees or ones with low working years as well as their awareness of protection, and standardize the relevant operational procedures, which can significantly improve the prevention of blood-borne occupational exposure and stress management of medical staff.
