Abstract Objective: To monitor the specific data and classification of acquired infections in abdominal emergency surgery, to evaluate the main risk factors of hospital infections of abdominal emergency surgery, to improve the quality of target monitoring, and to formulate reliable preventive measures targeted to effectively reduce the occurrence of hospital infections. Methods: Through effective monitoring and analysis of the clinical data collected in 2016, the main types of infections found were analyzed by single-factor and multi-factor analysis to find the risk factors of infection, and PDCA management was carried out.The task was expected to be completed in 2019. Statistics of relevant data were conducted through SPSS19.0 to confirm the effectiveness of PDCA. Results: In 2016, the incidence of general hospital infections was 7.91%, with surgical site infection (SSI) as the main type of infection, accounting for 3.6%. Through the collection and analysis of clinical data, it was found that the susceptibility factors of SSI are: The incidence of SSI with NNIS score ≥ 3 is higher than that with NNIS score <3; the difference was statistically significant (χ2=12.687, P<0.05). The incidence of SSI with irrational use of antimicrobials before surgery is higher than that of SSI with reasonable use of antimicrobials before surgery; the difference was statistically significant (χ2=9.092, P<0.05). The incidence of SSI with operation time ≥3h is higher than that with operation time <3h; the difference was statistically significant (χ2=9.087, P<0.05). Through the precise application of PDCA management, the incidence of SSI in 2019 dropped significantly from 3.6% to 1.33% (χ2=3.565, P<0.05).Conclusion: NNIS score ≥3, and irrational use of antimicrobials before surgery can be risk factors for infection of the surgical site. Effective PDCA management for the main risk factors mentioned above can effectively reduce the incidence of SSI.
