[Construction and application of virtual simulation teaching platform for in-hospital emergency nursing of craniofacial injury patients].

PURPOSE: To construct a virtual simulation teaching platform for in-hospital emergency nursing of craniofacial injury patients by virtual simulation technology, and to evaluate its application effect. METHODS: Through virtual reality, animation, human-computer interaction and other technologies, a 3D experiment scene based on high simulation virtual human was constructed to reproduce the virtual rescue scenes of craniofacial injury patients, such as emergency reception, first-aid cooperation, massive hemorrhage rescue cooperation, and tracheotomy cooperation in emergency rescue of sudden airway obstruction, and exercise modules and assessment modules were set. In the virtual simulation platform, the students used the holistic nursing theory and the PDCA cycle method to observe, evaluate and care for craniofacial injury patients. Preliminary evaluation of the platform was carried out in the training of 62 dental nurses. RESULTS: The virtual simulation platform could improve students' comprehensive first-aid ability for craniofacial injury patients. The item with the highest satisfaction rate for the virtual simulation platform was the consistency between the content of the virtual simulation platform and the theoretical course (the satisfaction rate was 91.9%), and the lowest satisfaction rate was the convenience of the virtual simulation platform operation and the page setting (the satisfaction rate was 80.6%). The evaluation module of the virtual simulation platform showed that the highest score of the comprehensive evaluation was 97, the lowest score was 56, and the average score was 80.2. CONCLUSIONS: The virtual simulation teaching platform for in-hospital first aid of craniofacial injury patients can create an immersive learning mode, provide an intuitive rescue experience to the students, and improve their comprehensive first-aid ability.

[Current status of oral health literacy and its influencing factors among adult orthodontic patients].

PURPOSE: To investigate the current status of oral health literacy among adult orthodontic patients and analyze its influencing factors. METHODS: Totally 163 adult orthodontic patients were recruited by convenience sampling method from November 2021 to February 2022 at the Department of Oral and Craniomaxillofacial Surgery, Center of Craniofacial Orthodontics in Shanghai Ninth People's Hospital. General information questionnaire, Chinese version of Health Literacy in Dentistry (HeLD-14), Chinese version of Self-Efficacy Scale for Self-care (SESS) and Social Support Rating Scale (SSRS) were applied. SPSS 21.0 software package was used for data analysis. RESULTS: The mean score of oral health literacy in adult orthodontic patients was (48.74±5.54), and the lowest score were obtained in concern (6.80±1.19) and support (6.40±1.59) dimensions. Multiple stepwise regression analysis showed that adult orthodontic patients' consultation self-efficacy, social support utilization, family or friends' orthodontic history and objective support were the influencing factors of oral health literacy. CONCLUSIONS: The oral health literacy in adult orthodontic patients is at a middle to high level, but concern and support literacy need to be improved. Strengthening consultation self-efficacy, objective support and utilization of social support can improve adult orthodontic patients' oral health literacy. Attention should be paid to patients who have no relatives or friends with history of orthodontic treatment.

[Analysis of information needs of patients with dentofacial deformities at different stages of treatment].

PURPOSE: To investigate the treatment experience and information needs of patients with dentofacial deformities in the process of surgical program design, surgical treatment and postoperative rehabilitation. METHODS: Thirty-six patients with dentofacial deformities at different treatment stages from March to July 2019 were selected for semi-structured interview. Colaizzi content analysis method and QSR NVivo 12.0 software were used to analyze and code the data, as well as extract the theme and genus. RESULTS: Three themes and eight categories were extracted, including① information needs in different treatment stages, mainly specific content of information needs at pre-operative preparation stage, orthognathic perioperative stage and post-operative rehabilitation stage; ② information support methods, i.e., diversified information support methods and patients' recognition of internet information;③ patients' cognition difference,namely the difference between patients' psychological expectation and the results of operation. CONCLUSIONS: Due to the treatment characteristics of orthognathic surgery and individual cognitive differences of patients, there is a large demand for information support at different stages of treatment. However, the current information support mode is limited, so it is necessary to further improve and provide scientific, professional and targeted information support for patients with dentofacial deformities.

[Qualitative study on the decision-making of orthognathic surgery in adult patients with malocclusion].

PURPOSE: The main purpose of this study was to explore the experience associated with patient's decision to have or not have orthognathic treatment. METHODS: Phenomenological methodology was used in this study. Ten patients were collected from January 2018 to March 2018, who were consulted in the Department of Oral and Craniomaxillofacial Surgery, Center of Craniofacial Orthodontics in Shanghai Ninth People's Hospital. They were interviewed by semi-structured, face to face in-depth interviews. Data were organized and analyzed by Colaizzi methods. RESULTS: By reading, analysis and extraction, two topics, i.e, motivation and interference factor were obtained. CONCLUSIONS: The treatment information service was limited. Further research is needed to improve the information services that support the treatment decision of malocclusion patients and help them to make the best choice.

[Influential factors analysis of positive psychology in patients with oral and maxillofacial trauma].

PURPOSE: To investigate the positive psychological reaction of patients with oral and maxillofacial trauma and related factors. METHODS: One hundred and five hospitalized patients with oral and maxillofacial trauma were investigated by self-designed general data questionnaire, positive psychological scale posttraumatic growth evaluation of quantitative PTG, and self-image questionnaire. SPSS 18.0 software package was used to analyze the data. RESULTS: Positive psychological score of the patients was 56.01±17.322, and self-image average score was 51.33±7.306. There were significant differences between male and female patients after trauma in new possibilities, personal power, self transformation and personal feeling (P<0.05); there was no significant difference between different ages in positive psychological reaction.With the improvement of educational level of patients, better personal power (P=0.031) and self transformation (P=0.01), and more positive psychological reaction were observed; Posttraumatic positive psychology of patients was negatively correlated with self-image score (r=-0.318, P<0.001). CONCLUSIONS: The male patients with oral and maxillofacial trauma have more positive attitude than female. With the improvement of educational level, more positive psychological reaction was documented in term of personal strength, self-transformation,but no obvious change in relationship with others, new possibilities and personal feeling. The better self image, the more positive psychological reaction was displayed.

[Establishment of an evidence-based protocol for tracheotomy care in adult patients].

PURPOSE: To establish a clinical practice protocol for tracheotomy care of adult patients. METHODS: Though constructive document retrieval, personnel interview and brain-storming, protocol draft was constructed. Delphi method was used in the study, and the final protocol was based on two rounds of consultation among 15 experts from 10 tertiary general hospitals. SPSS 16.0 software package was used for statistical analysis. RESULTS: The effective rates of two rounds of questionnaire were 100% and 93.3%, the authority coefficient was 0.83, and the P value of expert coordination coefficients W was less than 0.05. The final evidence-based protocol for tracheotomy care in adult patients consists of 5 sections, 16 dimensions and 61 items. CONCLUSIONS: The evidence-based tracheotomy care protocol was combined with Chinese clinical status and experts' opinion. The protocol was scientific and credible, which may play an important role in clinical practice.
