To analyze the current situation and influencing factors of post competency of full-time staff in nosocomial infection management in different levels of medical institutions in Guizhou Province.

Based on the principle of convenience sampling, 69 tertiary hospitals and 151 secondary hospitals in 9 cities (regions) of Guizhou Province were selected, and 766 full-time staff of nosocomial infection management were investigated by questionnaire. Multiple linear regression method was used for multivariate analysis.

The total score of post competence of full-time staff of nosocomial infection management in tertiary medical institutions (5.287 ±1.074) was higher than that in secondary medical institutions (4.835 ±1.194). The full-time staff of the third-level medical institutions outperformed those of the second-level medical institutions in terms of the overall level of competency, the self-evaluation scores of 4 core items, and self-evaluation scores of 11 sub-items (t=5.580, P<0.001). The scores of tertiary medical institutions and secondary medical institutions had the lowest score in comprehensive knowledge items, which were (4.394 ±1.401) and (3.614 ±1.529), respectively. The results of multiple regression analysis showed that the professional titles of the full-time staff of nosocomial infection management (B=-0.541, 95%CI:-1.024 to -0.058), the application level of office software (B=-0.854, 95%CI: -1.108 to -0.599), the importance degree the hospital attached to infection control (B=-0.393, 95%CI: -0.707 to -0.078), and the construction of the nosocomial infection control management system (B=-0.759, 95%CI: -1.314 to -0.204) were the independent factors for the post competency in tertiary medical institutions. The age of the full-time staff in the secondary medical institution (B=0.942, 95%CI: 0.435-1.449), the average monthly income (B=0.535, 95%CI: 0.165-0.905), and the application level of office software (B=-0.657, 95%CI: -0.909 to -0.405) were independent factors for the post competency in secondary medical institutions.

The overall post competency of the full-time staff of nosocomial infection management in Guizhou Province is at the upper-middle level, and the full-time staff of the tertiary medical institutions are obviously better than the secondary medical institutions.
