title: [Monitoring of hematogenous occupational exposure in medical staff in infectious disease hospital].
abstract: OBJECTIVE
  To investigate the status and risk factors for hematogenous occupational exposure in medical staff in an infectious disease hospital, and to provide a scientific basis for targeted preventive and control measures.
  
  
  METHODS
  The occupational exposure of 395 medical workers in our hospital was monitored from January 2012 to December 2014, among whom 79 individuals with occupational exposure were subjected to intervention and the risk factors for occupational exposure were analyzed.
  
  
  RESULTS
  The high-risk group was mainly the nursing staff (69.6%). The incidence of hematogenous occupational exposure was high in medical personnel with a working age under 3 years, aged under 25 years, and at the infection ward, accounting for 63.3%, 72.1%, and 72.2%, respectively. Hepatitis B virus, hepatitis C virus, Treponema pallidum, and human immunodeficiency virus were the primary exposure sources. Sharp injury was the major way of injury (91.1%), with needle stick injury accounting for the highest proportion (86.1%). Injury occurred on the hand most frequently (91.1%). The high-risk links were improper disposal during or after pulling the needle, re-capturing the needle, and processing waste, accounting for 46.8%, 17.7%, and 12.7%, respectively. Seventy-nine professionals with occupational exposure were not infected.
  
  
  CONCLUSIONS
  The main risk factor for hematogenous occupational exposure in medical staff in the infectious disease hospital is needle stick injury. Strengthening the occupational protection education in medical staff in infectious disease hospital, implementing protective measures, standardizing operating procedures in high-risk links, and enhancing the supervision mechanism can reduce the incidence of occupational exposure and infection after exposure.
