    Abstract
  •   Objective  To analyse the risk factors of cross-infection in orthodontic patients and to develop relevant predictive nursing intervention measures.  Methods  A total of 68 patients with cross-infection who received orthodontic treatment in our hospital from March 2017 to December 2019 were selected as the infection group, and 70 patients without cross-infection in our hospital during the same period were selected as the control group. The etiological distribution of infection group was analysed, and the related factors that may lead to cross-infection in patients with general information, disease data, and treatment related data were counted.  Results  A total of 134 strains of gram-negative bacteria (79.3%) were detected in the infection group. Most of them were Actinobacillus actinomycetemcomitans, Fossett's bacteria, and Porphyromonas gingivalis. A total of 35 strains (20.7%) were gram-positive bacteria. Most of them were oral Streptococcus, Staphylococcus aureus, and Staphylococcus epidermidis. Univariate analysis showed significant differences in age, diabetes mellitus, non-use of disposable instruments, unqualified disinfection of instruments, nonstandard operation of doctors, low level of protection awareness of medical staff, and substandard disinfection of air and environment between the two groups (all P < 0.05). Results of multivariate logistic analysis showed that significant differences were observed between the two groups in terms of age, diabetes mellitus, and non-use of disposable instruments and devices. The risk factors of cross-infection in orthodontic patients were as follows: unqualified mechanical disinfection, nonstandard operation of doctors and nurses, low level of protection awareness of medical staff, and substandard air and environment disinfection (all P < 0.05).  Conclusion  The main pathogen of cross-infection in orthodontic patients is gram-negative bacteria. Many risk factors lead to infection in patients. Predictive nursing intervention should be performed to improve prevention awareness.
