Methods: The questionnaires were randomly distributed to the anesthesiologists who participated the 22<sup>nd</sup> annual meeting of Chinese society of anesthesiology. The main contents of this survey included the arterial line managing status, the incidence of arterial line occlusion, the effects of arterial line occlusion on the anesthesiologists’ therapy and consequences caused by arterial line occlusion. Results: Totally 294 questionnaires were collected, in which 261 questionnaires were valid. In all respondents, 28.3% expressed that they could not flush arterial line on time, and 95.4% had experienced flushing arterial line only or sometimes or occasionally when the arterial waveform was not normal. Furthermore, 93.9% had experienced partial occlusion of the arterial line, and 79.3% had experienced complete occlusion. According to the serious recall of the respondents, the incidence of partial arterial line occlusion was 17.7% ± 22.0%, and the incidence of complete arterial line occlusion was 3.6% ± 8.1%. For all the respondents, 89.7% had experienced suspecting arterial line occlusion while real hypotension occurred, 65.1% had experienced not treating hypotension timely due to this suspicion, and 31% had experienced serious consequences caused by this suspicion. Conclusion: The incidence of arterial line occlusion is high during invasive blood pressure monitoring, which is a threat to the patients’ safety. So, intensive attention should be paid to the arterial line management.展开更多

rates of AMR,posing a threat to effective treatment.The World Health Or-ganization(WHO)Access,Watch,Reserve(AWaRe)classification system was introduced to address this issue and guide appropriate antibiotic prescribing.However,there is a lack of studies examining the prescribing patterns of antimi-crobials using the AWaRe classification,especially in North India.Therefore,this study aimed to assess the prescribing patterns of antimicrobials using the WHO AWaRe classification in a tertiary care centre in North India.Ophthalmology,Obstetrics and Gynecology).Metronidazole and ceftriaxone were the most prescribed antibiotics.According to the AWaRe classification,57.61%of antibiotics fell under the Access category,38.27%in Watch,and 4.11%in Reserve.Most Access antibiotics were prescribed within the Medicine department,and the same department also exhibited a higher frequency of Watch antibiotics prescriptions.The questionnaire survey showed that only a third of participants were aware of the AWaRe classification,and there was a lack of knowledge regarding AMR and the potential impact of AWaRe usage.RESULTS The research was carried out in accordance with the methodology presented in Figure 1.A total of n=123 patients were enrolled in this study,with each of them receiving antibiotic prescriptions.The majority of these prescriptions were issued to inpatients(75.4%),and both the Medicine and Surgical departments were equally represented,accounting for 49.6%and 50.4%,respectively.Among the healthcare providers responsible for prescribing antibiotics,72%were Junior Residents,18.7%were Senior Residents,and 9.3%were Consultants.These findings have been summarized in Table 1.The prescriptions included 27 different antibiotics,with metronidazole being the most prescribed(19%)followed by ceftriaxone(17%).The mean number of antibiotics used per patient was 1.84±0.83.The mean duration of antibiotics prescribed was 6.63±3.83 days.The maximum number of antibiotics prescribed per patient was five.According to the AWaRe classification,57.61%of antibiotics fell under the Access,38.27%in Watch,and 4.11%in Reserve categories,suggesting appropriate antibiotic selection according to these criteria.The distribution of antibiotics prescribed according to the WHO AWaRe categories is presented in Figure 2.The difference in prescribing frequencies amongst departments can be noted.Most of the antibiotics prescribed in the Access category were from the Medicine department(75.4%),followed by Surgery(24.6%).For Watch antibiotics,Medicine had a higher proportion(63.4%)compared to Surgery(36.6%).In terms of seniority,Junior Residents prescribed the highest number of antibiotics for both Access and Watch categories in Medicine and Surgery departments.Senior residents and Consultants prescribed a lower number of antibiotics in all categories and departments.Only a few antibiotics were prescribed in the Reserve category,with most prescriptions being from the Medicine department.The study also evaluated the Knowledge and Awareness of Healthcare professionals towards the WHO AWaRe classi-fication through a questionnaire survey.A total of 93 participants responded to the survey.Among them,most parti-cipants were Junior Residents(69.9%),followed by Senior Residents(25.8%)and Faculty(4.3%).When enquired if they knew about the WHO AWaRe classification only 33.3%of the participants responded positively.Of those who were aware of the AWaRe classification,the most common source of information was the internet(31.2%),followed by the antimicrobial policy of their institution(15.1%)as seen in Table 2.The survey results on the knowledge and awareness of AMR among healthcare professionals are also presented in Tables 3 and 4.Out of the 93 participants,68(73.1%)agreed that the emergence of AMR is inevitable,while only 13(14.0%)disagreed that AWaRe usage will result in the inability to treat serious infections.Additionally,58(62.4%)agreed that it will lead to lengthier hospital stays,43(46.2%)agreed that the success of chemotherapy and major surgery will be hampered,and the majority also agreed that its use will lead to increased cost of treatment and increased mortality rates.Regarding the utilization of AWaRe in the hospital summarized in Tables 4 and 5,35.5%of the participants agreed that it should be used,while only 2.2%disagreed.Additionally,34.4%agreed that AWaRe reduces adverse effects of inappro-priate prescription.However,37.6%of the participants considered that AWaRe threatens a clinician's autonomy and 30.1%thought that its use can delay treatment.Additionally,the DDD of each drug was also evaluated.The usage of various antimicrobial drugs in a hospital setting,along with their daily doses and DDD according to the WHO's Anatomical Therapeutic Chemical classification system was calculated.Some of the important findings include high usage rates of ceftriaxone and metronidazole,and relatively low usage rates of drugs like colistin and clindamycin.Additionally,some drugs had wider ranges than others.Comparison of WHO defined DDD with Daily Drug dose(Mean)in the studied prescriptions is represented in the Clustered Bar chart in Figure 3.Finally,the Mean Daily Drug Dose for prescribed drugs was compared with WHO defined DDD for each drug using a Student’s T test.The mean daily drug dose of amoxy/clav was significantly higher than the WHO DDD(1.8 vs 1.50,P=0.014),while the mean daily drug dose of metronidazole and doxycycline were significantly lower than the WHO DDD(P<0.001 and P=0.008,respectively).The mean daily drug dose of piperacillin/tazobactam,amikacin,clindamycin,and levofloxacin did not show significant differences compared to the WHO DDD(P>0.05).CONCLUSION This research indicates an appropriate proportion of prescriptions falling under the Access category(57.61%),suggesting appropriate antibiotic selection,a significant proportion also belongs to the Watch category(38.27%),emphasizing the need for greater caution to prevent the escalation of AMR.There is a moderate level of awareness among healthcare professionals about AMR and the steps being taken to tackle it,highlighting the gap in implementation of policies and need for more steps to be taken in spreading the knowledge about the subject.However,there is a significant difference between the WHO DDD and the prescribed daily dose in the analysed prescriptions suggesting overuse and underuse of antibiotics.展开更多

This study assessed prevalence and risk factors for stress, depression, and anxiety (SDA) in medical students during quarantine by COVID-19. Methods: A cross-sectional observational study of medical students by means of the DASS-21 questionnaire. Risk factors for SDA were assessed based on epidemiologic questions related to COVID-19. Receiver Operating Characteristics (ROC) curves were calculated for each predictor, as well as sensitivity and specificity. Results: This survey reached 1009 responses. A prevalence of 77.5% for some SDA disorder was found, 63% being severe. Previous diagnosis of psychiatric disorder was a factor of risk for anxiety (OR 2.78 CI95% 1.44 - 14.25, p = 0.044), as well as for depression (OR 3.37 CI95% 1.98 - 6.02, p Conclusion: Psychiatric conditions as well as chronic illnesses were risk factors for high prevalence of anxiety, depression and stress during the COVID-19 pandemic among medical students.展开更多

文摘Objective: The objective is to investigate the incidence and consequences of arterial line occlusion during invasive blood pressure monitoring in the form of questionnaire survey. Methods: The questionnaires were randomly distributed to the anesthesiologists who participated the 22<sup>nd</sup> annual meeting of Chinese society of anesthesiology. The main contents of this survey included the arterial line managing status, the incidence of arterial line occlusion, the effects of arterial line occlusion on the anesthesiologists’ therapy and consequences caused by arterial line occlusion. Results: Totally 294 questionnaires were collected, in which 261 questionnaires were valid. In all respondents, 28.3% expressed that they could not flush arterial line on time, and 95.4% had experienced flushing arterial line only or sometimes or occasionally when the arterial waveform was not normal. Furthermore, 93.9% had experienced partial occlusion of the arterial line, and 79.3% had experienced complete occlusion. According to the serious recall of the respondents, the incidence of partial arterial line occlusion was 17.7% ± 22.0%, and the incidence of complete arterial line occlusion was 3.6% ± 8.1%. For all the respondents, 89.7% had experienced suspecting arterial line occlusion while real hypotension occurred, 65.1% had experienced not treating hypotension timely due to this suspicion, and 31% had experienced serious consequences caused by this suspicion. Conclusion: The incidence of arterial line occlusion is high during invasive blood pressure monitoring, which is a threat to the patients’ safety. So, intensive attention should be paid to the arterial line management.

文摘BACKGROUND The overuse and misuse of antimicrobials contribute significantly to antimicrobial resistance(AMR),which is a global public health concern.India has particularly high rates of AMR,posing a threat to effective treatment.The World Health Or-ganization(WHO)Access,Watch,Reserve(AWaRe)classification system was introduced to address this issue and guide appropriate antibiotic prescribing.However,there is a lack of studies examining the prescribing patterns of antimi-crobials using the AWaRe classification,especially in North India.Therefore,this study aimed to assess the prescribing patterns of antimicrobials using the WHO AWaRe classification in a tertiary care centre in North India.Ophthalmology,Obstetrics and Gynecology).Metronidazole and ceftriaxone were the most prescribed antibiotics.According to the AWaRe classification,57.61%of antibiotics fell under the Access category,38.27%in Watch,and 4.11%in Reserve.Most Access antibiotics were prescribed within the Medicine department,and the same department also exhibited a higher frequency of Watch antibiotics prescriptions.The questionnaire survey showed that only a third of participants were aware of the AWaRe classification,and there was a lack of knowledge regarding AMR and the potential impact of AWaRe usage.RESULTS The research was carried out in accordance with the methodology presented in Figure 1.A total of n=123 patients were enrolled in this study,with each of them receiving antibiotic prescriptions.The majority of these prescriptions were issued to inpatients(75.4%),and both the Medicine and Surgical departments were equally represented,accounting for 49.6%and 50.4%,respectively.Among the healthcare providers responsible for prescribing antibiotics,72%were Junior Residents,18.7%were Senior Residents,and 9.3%were Consultants.These findings have been summarized in Table 1.The prescriptions included 27 different antibiotics,with metronidazole being the most prescribed(19%)followed by ceftriaxone(17%).The mean number of antibiotics used per patient was 1.84±0.83.The mean duration of antibiotics prescribed was 6.63±3.83 days.The maximum number of antibiotics prescribed per patient was five.According to the AWaRe classification,57.61%of antibiotics fell under the Access,38.27%in Watch,and 4.11%in Reserve categories,suggesting appropriate antibiotic selection according to these criteria.The distribution of antibiotics prescribed according to the WHO AWaRe categories is presented in Figure 2.The difference in prescribing frequencies amongst departments can be noted.Most of the antibiotics prescribed in the Access category were from the Medicine department(75.4%),followed by Surgery(24.6%).For Watch antibiotics,Medicine had a higher proportion(63.4%)compared to Surgery(36.6%).In terms of seniority,Junior Residents prescribed the highest number of antibiotics for both Access and Watch categories in Medicine and Surgery departments.Senior residents and Consultants prescribed a lower number of antibiotics in all categories and departments.Only a few antibiotics were prescribed in the Reserve category,with most prescriptions being from the Medicine department.The study also evaluated the Knowledge and Awareness of Healthcare professionals towards the WHO AWaRe classi-fication through a questionnaire survey.A total of 93 participants responded to the survey.Among them,most parti-cipants were Junior Residents(69.9%),followed by Senior Residents(25.8%)and Faculty(4.3%).When enquired if they knew about the WHO AWaRe classification only 33.3%of the participants responded positively.Of those who were aware of the AWaRe classification,the most common source of information was the internet(31.2%),followed by the antimicrobial policy of their institution(15.1%)as seen in Table 2.The survey results on the knowledge and awareness of AMR among healthcare professionals are also presented in Tables 3 and 4.Out of the 93 participants,68(73.1%)agreed that the emergence of AMR is inevitable,while only 13(14.0%)disagreed that AWaRe usage will result in the inability to treat serious infections.Additionally,58(62.4%)agreed that it will lead to lengthier hospital stays,43(46.2%)agreed that the success of chemotherapy and major surgery will be hampered,and the majority also agreed that its use will lead to increased cost of treatment and increased mortality rates.Regarding the utilization of AWaRe in the hospital summarized in Tables 4 and 5,35.5%of the participants agreed that it should be used,while only 2.2%disagreed.Additionally,34.4%agreed that AWaRe reduces adverse effects of inappro-priate prescription.However,37.6%of the participants considered that AWaRe threatens a clinician's autonomy and 30.1%thought that its use can delay treatment.Additionally,the DDD of each drug was also evaluated.The usage of various antimicrobial drugs in a hospital setting,along with their daily doses and DDD according to the WHO's Anatomical Therapeutic Chemical classification system was calculated.Some of the important findings include high usage rates of ceftriaxone and metronidazole,and relatively low usage rates of drugs like colistin and clindamycin.Additionally,some drugs had wider ranges than others.Comparison of WHO defined DDD with Daily Drug dose(Mean)in the studied prescriptions is represented in the Clustered Bar chart in Figure 3.Finally,the Mean Daily Drug Dose for prescribed drugs was compared with WHO defined DDD for each drug using a Student’s T test.The mean daily drug dose of amoxy/clav was significantly higher than the WHO DDD(1.8 vs 1.50,P=0.014),while the mean daily drug dose of metronidazole and doxycycline were significantly lower than the WHO DDD(P<0.001 and P=0.008,respectively).The mean daily drug dose of piperacillin/tazobactam,amikacin,clindamycin,and levofloxacin did not show significant differences compared to the WHO DDD(P>0.05).CONCLUSION This research indicates an appropriate proportion of prescriptions falling under the Access category(57.61%),suggesting appropriate antibiotic selection,a significant proportion also belongs to the Watch category(38.27%),emphasizing the need for greater caution to prevent the escalation of AMR.There is a moderate level of awareness among healthcare professionals about AMR and the steps being taken to tackle it,highlighting the gap in implementation of policies and need for more steps to be taken in spreading the knowledge about the subject.However,there is a significant difference between the WHO DDD and the prescribed daily dose in the analysed prescriptions suggesting overuse and underuse of antibiotics.
文摘Background: Measures to contain the COVID-19 transmission reached teaching routines of universities worldwide with possible mental health consequences for anxiety. This study assessed prevalence and risk factors for stress, depression, and anxiety (SDA) in medical students during quarantine by COVID-19. Methods: A cross-sectional observational study of medical students by means of the DASS-21 questionnaire. Risk factors for SDA were assessed based on epidemiologic questions related to COVID-19. Receiver Operating Characteristics (ROC) curves were calculated for each predictor, as well as sensitivity and specificity. Results: This survey reached 1009 responses. A prevalence of 77.5% for some SDA disorder was found, 63% being severe. Previous diagnosis of psychiatric disorder was a factor of risk for anxiety (OR 2.78 CI95% 1.44 - 14.25, p = 0.044), as well as for depression (OR 3.37 CI95% 1.98 - 6.02, p Conclusion: Psychiatric conditions as well as chronic illnesses were risk factors for high prevalence of anxiety, depression and stress during the COVID-19 pandemic among medical students.

文摘Urban parks are an important part of urban ecosystems and also provide recreational services for urban residents.However,it is still unclear how the recreational attractiveness of urban parks can be evaluated.In this study,12 typical parks in Changchun,China were selected for evaluation of their recreational attractiveness.We built a recreational attractiveness evaluation system based on the analytical hierarchy process(AHP)to produce a composite evaluation index.This method included:1)the landscape quality of the parks;2)the recreational facilities;3)the conditions of the area;and 4)the accessibility of the parks.Our results showed that Nanhu Park,Children’s Park,Shengli Park,and Jingyuetan Forest Park had high recreational attractiveness,whereas Linyuan Park had the lowest attractiveness among the 12 parks.These results agreed with the information obtained from a field survey of the actual recreational and revisit rates,which showed that the evaluation index is reliable.Correlation analysis showed that the landscape quality and recreational facilities of parks had a direct effect on their recreational attractiveness.A negative correlation was found between the accessibility of a park and its recreational attractiveness.We conclude that if the scenery and facilities are not as good as a visitor expects,then they may choose to visit a different park,even if it takes a longer time to reach.
文摘Objective: To compile nursing undergraduates' opinions and suggestions for biochemistry textbook to improve the readability and applicability of a textbook of biochemistry.Methods: This investigation involved 279 nursing undergraduates through delivery of a self-made questionnaire, which was to be used to analyze and study the students' suggestions and opinions on the content of the biochemistry textbook.Results: The investigation revealed that the textbook's difficulty was associated negatively with students' interest(P < 0.05), and the textbook's importance was associated positively with students' interest(P < 0.05). Students suggested that the textbook should be closely related to nursing. The contents,difficulty, structure and charts of the textbook should be adjusted properly.Conclusions: The content of the nursing version of the biochemistry textbook should be driven by the needs of the nursing major and should focus on simplifying the textbook's content, and making it practical. This will make the textbook vivid and readable, enhancing the interest of students to accept and benefit from the textbook.
文摘Over the last decade, the popularity of Transportation Network Companies (TNCs) as a mode of travel has been increasing at a steady pace. This trend <span style="font-family:Verdana;">highlights the importance of identifying the determinants that influence transportati</span><span style="font-family:Verdana;">on users to adopt TNCs as a preferred mode choice and the impacts of su</span><span style="font-family:Verdana;">ch preferences on their travel patterns and transportation network o</span><span style="font-family:Verdana;">peration. This paper reports on a recent study undertaken in Birmingham, AL aiming at understanding and documenting the factors that influence transportation users to select TNCs (such as Uber/Lyft) for completing typical day trips. In </span><span style="font-family:Verdana;">doing so, a travel diary questionnaire survey was developed in accordance with</span> <span style="font-family:Verdana;">the Institute of Transportation Engineers (ITE) Manual on Transportation Engineering Studies using the Qualtrics Research Core platform. The que</span><span style="font-family:Verdana;">stionnair</span><span style="font-family:Verdana;">e was used to survey over 450 transportation users in the Birmingham Metro area. The survey participants provided detailed trip information for a </span><span style="font-family:Verdana;">typical 24-hr day along with demographic data and travel preference informatio</span><span style="font-family:Verdana;">n. The survey responses provide high-resolution micro-level indicators </span><span style="font-family:Verdana;">of travel preferences and behaviors in a TNC-served area, which is a much-needed </span><span style="font-family:Verdana;">type of information for researchers and transportation planning agencies.</span>
