Investigation On Preventive Consciousness Of Cross-infection In Dentist And Nursing Staffs Of Stomatological Hospital

objectives:1. To investigate the status of dental practitioners about cross-infectionprevention and protection;2. To investigate the status of dental practitioners' knowledge aboutcross-infection;3. To analysis the factors affecting dental practitioners' behavior aboutcross-infection prevention and protection;4. To analysis the factors affecting dental practitioners' knowledge aboutcross-infection prevention and protection;5. To provide the first-hand data for the infection control instomatological hospital;6. To provide the decision-making basis for instituting relative regulationsabout cross-infection in stomatological hospitalMethods: 582 dental practitioners were randomly chosen from 5 hospitalsof stomatology. Software of EpiData3.0 was used to establish the database; Spss13.0 and SAS9.0 were used for statistical analysis.The methods of T test and AVOVA were used for the analysis ofthe practitioners' knowledge, opinion and behavior aboutcross-infection. Multiple linear regression and Pearson linearregression were used to investigate the affecting factors and therelevance between these affecting factors.Results:1. The status of dental practitioners' behavior about cross-infectionprevention and protection100% dental practitioners carried out the principle of one machine forone person, and 95.9% dental practitioners paid attention to the ventilationof the clinic. 86.9% medical staff have gloves when they treat patients,72.3% of those wash hands after and before treatment, and 73.7% of thosehad hepatitis Bvaccines injection; However, only 12.5% dentalpractitioners used new veil after treatment.2. The status of dental practitioners' knowledge about cross-infectionprotection and prevention83.3% of them thought that it was necessary to receive training aboutcross-infection protection and prevention. 75.4% of them thought they hadreceived the training, in whom 72% received training from the textbook and68.0% from academic meetings or cathedra.3. The effect of medical staff on behavior on cross-infection protection andpreventionThere is no significant difference in behavior on cross-infectionprotection and prevention among groups of different age, the title of a technical post or section office of medical staff. (P＞0.05) However, thereis significant difference in behavior on cross-infection protection andprevention among groups of different sex, academic career,occupation, work time or hospital of medical staff. (P＜0.05) The behavioron cross-infection protection and prevention of women is better than men,that of doctors is better than that of nurses. Graduate students on behavioron cross-infection protection and prevention got higher score than othergroups, the medical staff whose have 1 to 5years work experience(8.65±1.31 ) higher than those of more 20 years (8.14±1.55).HospitalⅤgot the highest score(8.51±1.35 ) and hospitalⅠgot the lowestscore(7.89±1.57)4. The multiple factor analysis result of dental practitioners' behavior oncross-infection protection and preventionGender (regression coefficient 0.737), degree (regression coefficient0.477) and the institution (regression coefficient 0.151), were the factorsaffecting dental practitioners' behavior on cross-infection protection andprevention.5. The effect of medical staff on knowledge about cross-infection protectionand preventionThere is no significant difference in knowledge about cross-infectionprotection and prevention among groups of different sex, age, occupation,the title of a technical post or work time of medical staff. (P＞0.05)However, there is significant difference in behavior on cross-infectionprotection and prevention among groups of different academic career,section office or hospital of medical staff. (P＜0.05) Graduate students onknowledge about cross-infection protection and prevention got higher score than other groups, however, the medical staff of the department ofProsthodontics, the department of Orthodontics, the department of lowerscore than those of other section office. The department of Orthodontics gotthe lowest score (7.27±1.79). There is significant difference in knowledgeabout cross-infection protection and prevention among medical staff ofdifferent hospitals. Furthermore, HospitalⅢgot the highestscore(8.42±1.17) and hospitalⅠgot the lowest score(6.71±1.52. Thegroup of professor got higher than other groups. (P＜0.05) The medical staffof the department of Orthodontics, the department of Prosthodontics,the department of Oral medical got lower score than those of other sectionoffice(the department of Protection, the department of Pediatric,theOral emergency department and the department of Implantology)(P＜0.05),and graduate student higher score than other groups.6. The multiple factor analysis result of dental practitioners' knowledge oncross-infection protection and preventionThe institution of dental practitioners was the factor affecting thedental practitioners' knowledge on cross-infection protection andprevention (the institution regression coefficient 0.286;the departmentregression coefficient 0.184)8. 7. There was positive correlation between dental practitioners' behaviorand knowledge on cross-infection protection and prevention (P=0.000,relevant coefficient r=0.232).Conclusion:1. The protection measures/behaviors against cross-infection should betaken and enhanced in dental practitioners; 2. There is a positive correlation between protecting behaviors andprotecting knowledge against cross-infection in dental practitioners, theprofessional education and training for cross-infection protectionshould taken and enhanced in systemic management.
