OBJECTIVE To study the risk factors and protection measures for the occupational exposure to HBV,and reduce the occupational exposure risk of blood.METHODS A survey was carried out among 1352 medical staff.And then we carried on the analysis to 43 questions of it and used Logistic regression analytic method to find out the risk factors and protective measures.RESULTS Seventy one persons had occuptional exposure risk to HBV and 56 persons had needle puncture wound or sharp wound.The risk factors included needle puncture wound or sharp wound,blood contaminated skin and mucous membrane,and the long working life.While knowledge of infection control,protection consciousness,washing hands,using gloves,and wearing glasses were the protective factors.CONCLUSIONS It plays the vital role to reduce occupational exposure to HBV that the medical staff should reduce injury in work,vaccinate the HBV vaccine,use protection goods and raise the protection consciousness.

Objective:To construct follow-up index system of ICU patients with acute kidney injury based on the Omaha nursing outcome classification system, and to provide a reference for the clinical care quality and the follow-up work of ICU patients after discharge.Methods:Based on the Omaha nursing outcome classification system, the Delphi method was used to establish the content of the follow-up index system for ICU patients with acute kidney injury, and determine the weight of all levels of indicators.Results:After two rounds of expert consultation, questionnaire response rates were 95.00%and 100.00%, expert authority coefficients were 0.861 and 0.892 (both P<0.01), coordination coefficients ranged from 0.296 to 0.667 and 0.240 to 0.804, the difference were statistically significant ( χ2 values were 60.77-288.17, and P<0.01). The final index system consisted of 4 first-level indicators, 16 second-level indicators, and 52 third-level indicators. The analytic hierarchy process was used to determine the weights of all indexes, and the consistency test (consistency ratio<0.1) was performed. Conclusions:The follow-up index system of ICU patients with acute kidney injury was constructed to provide a reference for the clinical care quality and the follow-up work of ICU patients after discharge, and to provide a theoretical basis for the follow-up mode after ICU.
