RESUMO
Objective To analyze the epidemic characteristics of road traffic injuries in Haishu District of Ningbo City and to provide evidence for effective prevention strategies. Methods Based on the "Ningbo Inpatient Injury Monitoring Report Card"， we analyzed the epidemiological characteristics and the influencing factors of hospitalization expenses using the road traffic injuries cases collected from 2015-2019 of Haishu District were analyzed. Results The ratio of male to female was 1.46∶1 among the 8 543 cases. Most cases were between 25 to 64 years old. There were 83.09% cases had junior high school education or below. The top three occupations in the cases were preschoolers， transportation workers， and retired people. Road traffic injuries occurred more frequently in spring for preschoolers and in summer vacation for school-age children. Motor vehicle accidents caused more serious injuries than non-motor vehicle accidents （χ 2=59.069， P<0.001）. The economic burden caused by the traffic injuries was heavy. The main influencing factors of hospitalization expenses for road traffic injuries were age， gender， severity of injury and the attribute of injury. The median hospitalization cost was 12 400 Yuan， and the interquartile distance was 23 400 Yuan. Conclusion Road traffic injury not only causes serious bodily injury， but also increases the economic burden of family and society directly or indirectly. Traffic safety education should be carried out for key groups to prevent the occurrence of road traffic injuries.
RESUMO
Objective:To conduct data mining on hospital accreditation results for inspirations and clues in hospital management.Methods:The Apriori function contained in the arules package of R software was used to extract the association rules. This practice aimed to analyze association rules of the accreditation results of 56 tertiary hospitals which were made based on tertiary hospital accreditation standard(2011)and Detailed Rules from 2017 to 2019; to explore the correlation between the clauses, and analyze the inspirations for hospital management.Results:A total of 6 566 138 and 247 rules were generated for all clauses and core clauses, receptively. The top 10 rules sorted by lift were selected as strong association rules. Among them, the minimum lift of all clauses and core clauses was 1.41 and 1.53, respectively. There was a strong correlation between the establishment of a quality and safety management team in the hospital and the development & implementation of relevant regulations by the hospital. There were strong correlations among emergency service procedure and regulations, patient rights to know, responsibility system by the first one to receive a complaint, medical safety(adverse)event reporting, development & implementation of antimicrobial management system, as well as training for prevention of multi-drug resistance infection measures, and multi-drug resistance infection hospital infection control system.Conclusions:This study suggested that hospital management should highlight the correlation between regulations development and staffing, that between indicator systems and monitoring feedback systems, and that between indicators in different sectors in the medical process. These correlations can be used as management clues and inspirations for hospital management.
