OBJECTIVE:To provide reference for the establishment of prevention and control measures for medication errors. METHODS:Based on JCI standard,51 cases of medication error reported by ADE information platform of our hospital in 2012 were summarized,and analyzed in terms of error type,error time,working life of responsible person,etc. The prevention and con-trol strategies were introduced. RESULTS:Referring to related requirements of JCI standard,medication errors reduced significant-ly during 2013-2014 through personnel training and education,system improvement and process optimization. CONCLUSIONS:Medication errors surveillance and control is important for the promotion of rational use of drugs. JCI standard has played an impor-tant role in monitoring and preventing medication errors.

Objective:To analyze the classification characteristics of nurses ′ perception of management care in tertiary Class A hospital in Tianjin and the differences in demographic characteristics among different categories, and provide reference for care managers to provide targeted care intervention. Methods:Totally 456 nurses from 6 tertiary Class A hospitals in Tianjin were selected by convenience sampling way from May to July 2020, and carried out surveys through the online questionnaire star platform. The content included general subject and the Chinese version of Caring Assessment Tool-administration Scale.Results:According to nurse management care perception totally 456 nurses were divided into 4 Latent groups: low decision-making respect and low care group (C1) 20.5% (94/456), moderate decision-making respect and high care group (C2) 35.6% (162/456), high decision-making respect and low care group (C3) 18.9% (85/456), high decision-making respect and high-care group (C4) 25.0% (115/456). Single factor analysis showed that there were statistically significant differences in the distribution difference of different categories of nurses in departments, working years, department atmosphere and family support ( χ2 values were 19.119-55.947, P<0.01). Multiple Logistic regression analysis showed that departments, working years, department atmosphere had an effect on the level of nurses management, care and perception ( P<0.05 or 0.01). Specifically, nurses in the internal medicine, obstetrics and gynecology and intensive care unit were more close to C2 group ( OR values were 2.435, 5.224, 22.291, P<0.05 or 0.01); nurses in the surgery were more close to C4 group ( OR values were 4.146, P<0.01); nurses with seniority of≤5 years were more close to C1 and C2 groups ( OR values were 0.326, 3.811, P<0.05 or 0.01); nurses with ordinary atmosphere were more close to C1 group ( OR value was 0.057, P<0.01). Conclusions:Nurses ′perception of management care is in the upper middle level, which can be divided into four potential categories. Nurses who are in the surgical department with high seniority or harmonious atmosphere or supportive families have good perception of management care; nurses who are in the department of internal medicine, obstetrics and gynecology, intensive care unit or a department with ordinary atmosphere or low seniority have an average level of management, care and perception, which need to be improved. Care managers could formulate targeted care management measures according to the characteristics of different categories of nurses.

Objective:Four cases with NLRP3-related autoinflammatory diseases were reported to summarize the clinical characteristics, genotype, and treatment responses of the disease, and to improve clinical pediatricians' understanding of the disease.Methods:A retrospective analysis was performed on 4 cases with NLRP3-related autoinflammatory diseases diagnosed in Children's Hospital of Anhui Province in 2016—2021, and the clinical features and treatment progress of NLRP3-related autoinflammatory diseases were retrospectively analyzed based on the clinical features, gene reports, and literature review.Results:① All 4 cases were male. Cases 1, 2, and 3 had the disease onset after birth, and case 4 had the disease onset 6 months after birth. All showed periodic fever, repeated urticaria-like rash, protruding forehead, and saddle nose. White blood cells count, erythrocyte sedimentation rate, and C-reactive protein were increased during the attack period, and those in the interval period were normal, and antibiotic treatment was ineffective. ② The genetic test of all these 4 children showed NLRP3 mutation. Children 1, 2, and 3 were heterozygous mutations, and their parents were wild-type. The mutation was located at chromosome Chr1: 247587658, exon c913 (exon3). G>A, the 305th aspartic acid (Asp) of the protein was changed to asparagine (Asn) in child 1. The mutation was located at the chromosomal Chr1: 247588072, the nucleic acid was changed to c1327(exon3)T>C, and the amino acid was changed to p.Y443H in cases 2 and 3. Somatic heterozygous mutation was found in case 4, and the child's parents were wild-type. In this case, the mutation was located at chromosomal Chr1: 247587658, exon3 G>A, and the 305th Asp of the protein was changed to Asn. ③Children in cases 1, 2, and 3 were treated with glucocorticoids and non-steroidal anti-inflammatory drugs at the initial stage, but the effects were limited. After receiving IL-1 antagonist treatment fever, skin rash, joint swelling and pain disappeared, and the inflammatory indexes were returned to normal. The child 4 received non-steroidal anti-inflammatory drugs and methotrexate, but he failed to respond to the treatment. Treatment with tocilizumab was not effective, however, fever, skin rash, or joint pain disappeared after treated with Khanna.Conclusion:①NLRP3-related autoinflammatory diseases can cause periodic fever, urticaria, joint involvement, and severe involvement of the central nervous system and organ amyloidosis. Which are early misdiagnosis is prone to systemic juvenile idiopathic arthritis. ②The disease was an inflammatory disease mediated by interleukin-1. At present, non-steroidal anti-inflammatory drug, glucocorticoid and chronic anti-rheumatic drugs have limited effects. IL-1 antagonists are effective and safe in the treatment of the disease.
