Comparison of the positive rate of microbiological examination in different clinical specimens

Objective To compare the positive rate of microbiological examination in different clinical specimens, and to provide reliable basis for improving the quality of microbiological examination and management of nosocomial infection. Methods A total of 2 028 bacterial culture specimens were collected from the hospitalized patients in the Second People's Hospital of Jinanfrom March 2016 to February 2018.The samples were examined by Micro Scan autoSCAN4 automatic bacteriological identification analyzer.Strictly according to the specification of the standard operation, the positive rates of microbial testingof all kinds of clinical specimens were statistically analyzed. Results The positive rate of microbiological examination in 2 028 clinical specimens was 44.33%.The positive rate of microbiological examination in sputum was the highest(58.96%), followed by ophthalmic secretion(40.64%), eye contents(37.96%), urine(34.55%), blood(21.11%). Conclusion The positive rate of microbiological examination is different in different clinical specimens.The epidemiological situation of nosocomial infection can be understood by analyzing the microbiological examination of different clinical specimens in clinic.In order to provide a reliable basis for clinical prevention and treatment of nosocomial infection, and to further improve the positive rate of clinical microbiological examination, we should actively carry out improvement countermeasures against its influencing factors.
