ObjectiveTo explore the risk factors for hematogenous occupational exposure by analyzing hematogenous occupational exposure in medical workers, and discuss countermeasures in order to reduce the occurrence of hematogenous occupational exposure in medical workers. MethodsWe summarized and analyzed the hematogenous occupational exposure reported by registered medical personnel in the First People's Hospital of Yibin City from January 2012 to December 2014. ResultsThere were 129 cases of hematogenous occupational exposure, and nurses were at high risk of such exposure (65.12%).The exposure occurrence focused in medical personnel with working time shorter than 5 years.The top three high-risk operational procedures were needle injection, puncture, and medical waste disposal; sharp instrument injuries (109 cases, 84.50%) were the main factor leading to hematogenous occupational exposure in medical workers.Sources of exposure were detected and confirmed in 92 cases (71.32%); after testing, 79 cases (61.24%) of infections were confirmed in the source patients with one or more blood-borne pathogens.Through scientific treatment, no infection after hematogenous occupational exposure was detected in the medical workers. ConclusionMonitoring and analysis of hematogenous occupational exposure can facilitate identification of key departments, target population and risk factors, which is important for taking appropriate interventions.
ObjectiveTo learn the status quo and characteristics of multi-drug resistant organism (MDRO) infection in a comprehensive hospital of the first grade in Sichuan Province, analyze the effect of prevention and control intervention, in order to provide a scientific basis for clinical MDRO prevention and control. MethodsWe collected MDRO data from January to June 2014 and from January to June 2015 through multi-drug resistance reporting software, and analyzed and compared the infection of MDRO during those two time periods. Then, we evaluated the prevention and control effect of MDRO infection. ResultsThe number of inpatients from January to June 2014 was 24709, among which 813 were detected with MDRO infection. Of those infected patients, 196 had nosocomial infection of MDRO and the other 617 had community infection/colonization. The proportion of nosocomial MDRO infection was 24.10%. The MDRO nosocomial infection case rate was 0.79%. The proportion of community MDRO infection/colonization was 75.90%. The number of inpatients from January to June 2015 was 25329, and 739 of them were found with MDRO infection, of whom 132 had nosocomial infection and 607 community infection/colonization. The proportion of nosocomial MDRO infection was 17.86%. The MDRO nosocomial infection case rate was 0.52%. The proportion of community infection/colonization was 80.14%. Compared with the first half of 2014, the proportion of nosocomial MDRO infection was lower with a statistically significant difference (χ2=9.062, P<0.001), and MDRO nosocomial infection case rate was also significantly lowered (χ2=14.220, P<0.001). There were significant differences between the first half of 2015 and the same period of 2014 in hospital department distribution of MDRO infection, patient infection site distribution and pathogen detection. ConclusionThe nosocomial MDRO infection control situation of our hospital is improved after the comprehensive prevention and control interventions, and we should focus on the prevention and control of key departments, important infection sites and major resistant bacteria in the future MDRO hospital infection control work.
