Objective:To analyze the association between continuity of consultation and the management of glycosylated hemoglobin (HbA1c) in diabetes patients contracted by family doctors.Methods:This study was a cross-sectional study. From May 2022 to October 2022, three community health service centers in the urban area of Beijing were selected by convenient sampling. A total of 360 diabetes patients were selected by simple random sampling from the selected centers. Extraction of data from electronic health records were conducted to collect patient characteristics, information on the continuity evaluation indicators for patient visits (usual provider of care, UPC) in 2021 and information of monitoring and control indicators for HbA1c in 2021. The monitoring and control of HbA1c in patients with different continuity of consultations were compared. Chi-square test and logistic regression analysis were used to determine the association between continuity of consultation and HbA1c management (i.e., HbA1c monitoring and control).Results:Of the 360 patients, 167 (46.4%) were male; the age was 68.0 (60.0, 74.0) years and the number of years since diagnosis was 11.0 (7.0, 17.0) years. One hundred and fifty-nine patients (44.1%) had UPC scores below 30%, 101 patients (28.1%) had UPC scores between 30% and 50%, and 100 patients (27.8%) had UPC scores above 50%. The compliance rate for HbA1c monitoring was 66.4% (239/360), and the compliance rate for HbA1c control was 45.8% (165/360). When the UPC score was less than 30%, between 30%-50%, and greater than 50%, the HbA1c monitoring compliance rates were 53.5% (85/159), 73.3% (74/101), and 80.0% (80/100), respectively, and the HbA1c control compliance rates were 37.7% (60/159), 51.5% (52/101), and 53.0% (53/100), respectively, and the differences were statistically significant ( χ2=22.36, 7.57, P<0.05). As the UPC score increased, the likelihood of achieving HbA1c monitoring ( OR=1.020, 95% CI:1.009-1.030 , P<0.001) and control ( OR=1.012, 95% CI:1.003-1.021 ,P=0.008) targets increased. Conclusion:There is an association between the continuity of consultation and the management of HbA1c.

Objective:To evaluate the reliability and validity of the Chinese version of Consultation and Relational Empathy (CARE) Measure in the Mandarin speaking population.Methods:From March to June 2018, patient interviews and expert consultations were conducted to explore problems of CARE in Mandarin context and preliminary revisions were made to the measure, then the final adapted tool was developed. A questionnaire survey on the validity of the measure was conducted from July to August 2018, among 373 patients from three community health service centers in Beijing Chaoyang District, selected by convenience sampling. The questionnaire included general information of participants and the revised CARE measure. The results of the survey were analyzed for the reliability and validity of Chinese version of CARE measure.Results:In the culture adaptation stage, 30 word-changes and 13 phrase-changes were made to improve the cultural adaptation of CARE. A total of 373 valid questionnaires were were collected with a valid recovery rate of 100.0%. The participants had a mean age of (60.8±13.12) years, with females of 68.6% (256/373), junior high school or high school education of 58.7% (219/373), and retirees of 71.3% (266/373). The results showed that there was a significant difference in scores of each item between the high group (top 27%) and the low group (bottom 27%) ( P<0.001). There was a positive correlation between each item and the total score, with a correlation coefficient between 0.817 and 0.868 ( P<0.001). The reliability analysis results show that the Cronbach′s α of the revised CARE was 0.960. In the content validity analysis, among the 10 items, the proportion of patients who considered the item "not applicable" was between 1.1% and 4.8%, and the proportion who considered the item "important" was between 92.8% and 96.2%. In exploratory factor analysis, KMO=0.944 and Bartlett′s sphericity test P<0.001. One common factor with an eigenvalue>1 was extracted, and the cumulative variance explained by which was 73.85%, with the load value of each item of 0.815-0.909. Conclusion:The revised Chinese version of CARE measure shows good reliability and validity and it can be applied in primary care settings for Mandarin speaking population.

Objective:To characterize the epidemiology of respiratory syndrome across healthcare facilities of different types and tiers in Beijing City, to compare pathogen-testing modalities and their associations with adverse outcomes, and to identify key factors associated with progression to severe illness, thereby informing regional prevention, control, and clinical optimization.Methods:The multicenter observational cohort study was performed using outpatient and emergency department data from five sentinel hospitals in Beijing (Beijing Xiaotangshan Hospital, Beijing Chaoyang District Shuangqiao Hospital, Beijing Haidian Hospital, Beijing You′an Hospital, Capital Medical University (Beijing You′an Hospital), and Beijing Ditan Hospital, Capital Medical University (Beijing Ditan Hospital)) from October 1st, 2023 to April 9th, 2025. Dual-target (two-plex) and triple-target (three-plex) respiratory specimens were collected. Demographic characteristics, visit information, pathogen-testing modalities and results were collected, and the epidemiologic features of patients who progressed to severe illness between the influenza high-incidence season (December to May) and the non-influenza season (June to November) were compared. Categorical variables were analyzed using the chi-square test. Multivariable logistic regression was used to estimate associations between covariates and risk of progression to severe illness.Results:Among the 192 131 cases, patients visited at Beijing You′an Hospital were concentrated in the 16 to 44 year age group, accounting for 66.79%(32 532/48 708). Beijing Xiaotangshan Hospital had a broad age distribution, with older adults comprising up to 22.35% (885/3 960). Of the 47 349 respiratory specimens across the five hospitals, Beijing You′an Hospital had the highest positivity rate for dual-target testing (46.76%(1 585/3 390)), while Beijing Haidian Hospital conducted the largest number of this tests ( n=12 514). For triple-target testing, Beijing You′an Hospital again had the highest positivity rate (45.03%(2 835/6 296)), whereas Beijing Ditan Hospital tested the most specimens ( n=12 011; positivity rate was 29.73%(3 571/12 011)). The influenza season within the same period (November 2023 to January 2024) exhibited a bimodal pattern, with alternating circulation of influenza viruses and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Among 32 744 outpatients/emergency patients who progressed to severe illness, significant seasonal differences were observed by sex, age, comorbidity status, and infection type ( χ2=6.60, 189.24, 32.71 and 189.99, respectively; all P<0.05). After adjustment for sex, age group, comorbidities, and infection type, testing modality remained significantly associated with risk of progression (dual-target testing, odds ratio ( OR)=0.116, 95% confidence interval ( CI) 0.111 to 0.122, P<0.001); no testing, OR=0.063, 95% CI 0.060 to 0.065, P<0.001). Conclusions:The epidemiological pattern of respiratory pathogens undergo significant changes after October 2023, which is characterized by alternating waves of influenza viruses and SARS-CoV-2 with pronounced seasonality and diversity. Substantial inter-hospital differences are observed in testing modalities and positivity rates. Risk of progression to severe illness varies significantly by sex, age, comorbidity burden, and infection type, and is closely associated with the testing modality. These findings support strengthening multiplex pathogen testing and targeted surveillance of high-risk groups to improve early identification and precise control of febrile-respiratory syndromes.

OBJECTIVE To analyze the status of targeted monitoring of the health care-associated infections in in-tensive care unit(ICU)of a three-A hospital of northwest China in recent 7 years so as to provide bases for formu-lating effective prevention and control measures for the health care-associated infections.METHODS The related data were successively collected from the ICU hospitalized patients of the Second Affiliated Hospital of Air Force Medical University who were under the targeted monitoring by nosocomial infection real-time monitoring system from Jan.2017 to Dec.2023.The data included the incidence of infections,infection sites,use of catheters,inci-dence of catheter-related infections,and distribution and prevalence trend of pathogens.RESULTS A total of 49,137 hospitalized patients from five ICU wards of respiratory medicine department,neurosurgery department,neurology department,thoracic surgery department and critical care medicine department were under the monito-ring,1446(1681 case-times)of whom had health care-associated infections,with the infection rate 2.94％,the case-time infection rate 3.42％.The respiratory system was the major infection site of the patients with the health care-associated infections.Among the patients with instrument-associated infections,20.70％had ventilator-asso-ciated pneumonia(VAP),5.71％had urinary catheter-associated urinary tract infection(CAUTI),and 1.96％had catheter-related bloodstream infection(CRBSI).Totally 405 strains of non-repetitive pathogens were isolated from 477 patients with instruments-associated infections,78.77％of which were gram-negative bacteria.The iso-lation rate of multidrug-resistant organisms(MDROs)was 44.12％,and Acinetobacter baumannii was the pre-dominant species of pathogen isolated from the patients with VAP.CONCLUSIONS The targeted monitoring of health care-associated infections may facilitate the awareness of dynamic changes of the infections in a accurate and timely manner so as to provide bases for developing effective prevention and control measures for the health care-associated infection.It is necessary to strengthen the prevention and control of the infections in critical care medi-cine department,neurosurgery department as well as the lower respiratory tract infections and prevent the MDROs infection in the meantime.
