Objective:To construct a representative index system for evaluating pediatric orthopedic nursing quality, providing a basis for hospital pediatric orthopedic nursing quality assessment and monitoring.Methods:From April to July 2023, using the "structure-process-outcome" three-dimensional quality structure model as the theoretical framework, a literature review was conducted, and an item pool was formulated. Through two rounds of Delphi method expert consultations, the hierarchical analysis method was finally employed to determine the indicators and their weights at each level.Results:The effective recovery rates of the questionnaire of the two rounds of expert consultations were 100% (20/20), the authority coefficients of experts were 0.87 and 0.88, the coefficients of variation were 0.00 to 0.27 and 0.00 to 0.24. The Kendell harmony coefficients of the second and third indicators in the two rounds of inquiry were 0.140, 0.166 and 0.192, 0.161(all P<0.05). The final pediatric orthopedic nursing quality evaluation index system included 3 primary indicators, 21 secondary indicators and 83 tertiary indicators. Among the primary indicators, the weight of process quality was the highest at 0.493 4, followed by outcome quality at 0.310 8, and the lowest was structural quality at 0.195 8. In the secondary indicators, "assessment criteria of limb blood circulation" had the highest weight at 0.099 8. Conclusions:The constructed pediatric orthopedic nursing quality evaluation index system covers key aspects and is more operationally feasible. It provides better guidance for nursing interventions and quality control.

Objective To explore the clinical application of ultrasound-guided transabdominal villus and amniocentesis in the prenatal diagnosis of thalassemia,and to find a suitable method for the prenatal diagnosis of thalassemia in Qinzhou.Methods A total of 531 high-risk pregnant women with severe or intermediate thalassemia during single pregnancy who were treated in the Department of Medical Genetics and Prenatal Diagnosis,Qinzhou Maternal and Child Health Hospital from March 2021 to April 2022 were selected for the study.According to different sampling methods,they were divided into control group(amniocentesis,n=415)and study group(transabdominal villus puncture,n=116).The success rate,complication rate of the two groups were compared.Results The success rate of puncture in the control group was 100％,2 cases were aborted within 2 weeks after surgery,17 cases were diagnosed with severe alpha-thalassemia,10 cases with severe β-thalassemia and 64 cases with intermediate thalassemia,48 cases with moderate and severe thalassemia induced labor.The success rate of puncture in the research group was 100％,10 cases were diagnosed with severe alpha-thalassemia,4 cases with severe β-thalassemia and 17 cases with intermediate thalassemia,and 26 cases with moderate severe thalassemia were induced labor.There was no significant difference in puncture success rate and abortion rate between the two methods(P>0.05).Conclusion Both methods are safe and effective.Transabdominal villus sampling can detect fetal thalassemia in early pregnancy,and it is worth promoting and applying in clinical practice.

Objective:Bacterial liver abscess is one of the common infectious diseases of the digestive system.Invasive Klebsiella pneumoniae liver abscess syndrome(IKLAS)refers to cases where,in addition to liver abscess,there are migratory infections foci or other invasive manifestations.The clinical characteristics and risk factors of IKLAS are not fully elucidated,and there is a lack of research on the effectiveness and cost-effectiveness of different treatment methods.This study aims to compare the clinical characteristics of patients with IKLAS and non-IKLAS,and explore effective and economical treatment methods. Methods:This retrospective study collected medical records of patients with Klebsiella pneumoniae liver abscess treated at Xiangya Hospital of Central South University from January 2010 to December 2023.A total of 201 patients were included,dividing into an IKLAS group(n=37)and a non-IKLAS group(n=164).Differences in demographics,symptoms and signs,laboratory indicators,imaging characteristics,comorbidities,treatment methods,treatment outcomes,and direct treatment costs between 2 groups were analyzed.The study also compared the effectiveness and costs of different treatment methods. Results:Compared with the non-IKLAS group,the proportion of patients with diabetes,Quick Sequential Organ Failure Assessment(qSOFA)≥2,immune deficiency,anemia,and thrombocytopenia in the IKLAS group was higher,and the level of procalcitonin at the onset in the IKLAS group was also higher(all P<0.05).In terms of symptoms and signs,the IKLAS group had a higher proportion of visual abnormalities and a lower proportion of complaints of abdominal pain(both P<0.05).In terms of complications,the incidence of combined pleural effusion,pulmonary infection,acute renal failure,respiratory failure,and multiple organ failure was higher in the IKLAS group(all P<0.05).The IKLAS group had a higher proportion of patients treated with antibiotics alone(24.32%vs 11.59%),while the non-IKLAS group had a higher proportion of patients treated with antibiotics combined with puncture and drainage(86.59%vs 64.86%,both P<0.05).The overall effective rate of the IKLAS group(83.78%)was lower than that of the non-IKLAS group(95.73%),and the treatment and drug costs were higher(all P<0.05).The treatment method of antibiotics combined with surgical resection of infectious foci showed a 100%improvement rate,antibiotics combined with abscess puncture and drainage had an 84.9%improvement rate,and in antibiotics alone had an 82.1%improvement rate,with statistical differences among the 3 treatment methods(P<0.05).In terms of treatment costs,antibiotics alone were the most expensive(P<0.05). Conclusion:Patients with IKLAS have poorer prognosis and higher direct medical costs.The combination of abscess puncture and drainage or surgery has a higher improvement rate and lower hospitalization costs compared to antibiotics alone,suggesting that surgical intervention may reduce antibiotic costs and save medical expenses.
