Objective To study the characteristics of invasive catheter infection in neurosurgery intensive care unit (NICU) to provide theoretical basis for the prevention of the infections.Method A retrospective analysis was done into the clinical data of 563 patients with indwelling catheter from January 2011 to December 2012 in our department.Results Among 563 cases undergoing invasive catheteration,there were 106 cases of catheter-associated infections with an incidence of 18.8%. The urinary catheter-associated infection was 24.5% and epidural drainage catheter-associated infection was 16.9%.Conclusion The enhanced consciousness of critical catheter infections,abiding by principles for aseptic operation and strengthened nursing to catheters or tubes are critical for reducing the incidence of invasive catheter-associated infections and ensuring the safety patients.

Objective To analyze the changes in the disease spectrum of hospitalized patients with neurological diseases in a tertiary hospital in the past 5 years,in order to effectively develop targeted disease prevention and treatment strategies.Methods Collect case data of neurological diseases in a tertiary hospital from January 1,2018 to December 31,2022,and use ICD-10 coding for disease classification,and analyze the disease type,gender,age groups,and other factors.Results A total of 9060 patients with neurological diseases were admitted in the past five years.In 2020,the number of discharged patients affected by the COVID-19 was the smallest,accounting for 15.96% ,and in 2022,the number was the largest,accounting for 24.05% .The number of cases showed an increasing trend.There was no statistically significant difference in the composition of male and female patients;There is a statistically significant difference in the number of cases among patients of different age groups,and the incidence categories are different;The top 10 diseases in the ranking of neurological diseases are:transient ischemic attack,headache,spinal nerve disease,neurological disorders,epilepsy,Parkinson's disease,sleep disorders,paralysis,other brain diseases,hydrocephalus.The distribution of the top 10 diseases by gender has statistical significance.Conclusion The hospital can formulate the diagnosis and treatment technology for different age groups according to the distribution characteristics of disease spectrum,carry out comprehensive prevention and treatment measures for key groups,strengthen the construction of key special-ties and allocate health resources properly.

Objective:To evaluate the quality of relevant practice guidelines for the prevention of surgical site infections in adult inpatients and provide a reference for formulating protocols to prevent surgical site infections in adults.Methods:Practice guidelines related to the prevention of surgical site infections in adults published up to June 2, 2020 were retrieved from domestic and foreign databases, guideline websites and the websites of professional societies. The Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) was used to evaluate the methodological quality of the included guidelines, and the intra-group correlation coefficient was used to test the consistency between the reviewers.Results:A total of 6 clinical practice guidelines were included, and in terms of the quality, there were 4 grade A guidelines and 2 grade B guidelines. The average standardized scores of AGREE Ⅱ in 6 dimensions were: 87.04% for scope and purpose, 76.62% for stakeholder involvement, 76.56% for rigor of development, 89.58% for clarity of presentations, 81.60% for applicability, and 81.25% for independence.Conclusions:The existing clinical practice guidelines related to the prevention of surgical site infections in adults are relatively comprehensive with a relatively good quality. Nursing staff need to consider the applicability of evidence application, formulate practical infection prevention strategies, and reduce the incidence of surgical site infections in adults.
