2019冠状病毒病(COVID-19)诊疗浙江经验 Management of COVID-19: the Zhejiang experience

当前2019冠状病毒病（COVID-19）疫情仍处于胶着状态。浙江大学医学院附属第一医院是国家感染性疾病临床医学中心，浙江省COVID-19患者救治中心。疫情一线的专家集智攻关，以国家卫生健康委员会和国家中医药管理局发布的COVID-19诊治指南为依据，以抗病毒、抗休克、抗低氧血症、抗继发感染、维持水电解质和酸碱平衡、维持微生态平衡的“四抗二平衡”救治策略为核心，总结完善诊治方案，聚焦临床实践的一些具体问题，为COVID-19患者临床诊治提供借鉴。推荐以多学科协作诊治个性化治疗提高COVID-19患者救治质量。建议病原学检测、炎症指标监测和肺部影像学动态观察指导临床诊治。痰液的病毒核酸检测阳性率最高，约10%的急性期患者血液中检测到病毒核酸，50%的患者粪便中检测到病毒核酸，粪便中可分离出活病毒，须警惕粪便是否具有传染性；开展细胞因子等炎症指标监测有助于发现是否出现细胞因子风暴，判断是否需要人工肝血液净化治疗。通过以“四抗二平衡”为核心的综合治疗提高治愈率、降低病死率；早期抗病毒治疗能减少重症、危重症发生，前期使用阿比多尔联合洛匹那韦/利托那韦抗病毒显示出一定效果。休克和低氧血症多为细胞因子风暴所致，人工肝血液净化治疗能迅速清除炎症介质，阻断细胞因子风暴，对维持水电解质酸碱平衡也有很好的作用，可以提高危重型患者的疗效。重型病例疾病早期可适量、短程应用糖皮质激素。氧疗过程中，患者氧合指数小于200 mmHg时应及时转入重症医学科治疗；采用保守氧疗策略，不推荐常规进行无创通气；机械通气患者应严格执行集束化呼吸机相关性肺炎预防管理策略；氧合指数大于150 mmHg时，及早减、停镇静剂并撤机拔管。不推荐预防性使用抗菌药物，对于病程长，体温反复升高和血降钙素原水平升高的患者可酌情使用抗菌药物；要关注COVID-19患者继发真菌感染的诊治。COVID-19患者有肠道微生态紊乱，肠道乳酸杆菌、双歧杆菌等有益菌减少，推荐对所有患者进行营养和胃肠道功能评估，以营养支持和补充大剂量肠道微生态调节剂，纠正肠道微生态失衡，减少细菌移位和继发感染。COVID-19患者普遍存在焦虑和恐惧心理，应建立动态心理危机干预和处理。提倡中西医结合辨证施治；优化重型患者护理促进康复。严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染后病毒清除规律仍不明了，出院后仍须居家隔离2周，并定期随访。以上经验和建议在本中心实行，取得较好效果，但COVID-19是一种新的疾病，其诊治方案及策略仍有待进一步探索与完善。

Mental health outcome and resilience among aiding Wuhan nurses: One year after the COVID-19 outbreak in China.

OBJECTIVE: This study aimed to explore whether aiding Wuhan experience of nurses was associated with adverse mental health outcome one year after the COVID-19 outbreak in China. METHODS: In this study, 100 nurses with and 100 nurses without aiding Wuhan experience a year ago were enrolled from February 1, 2021 to March 31, 2021 in Zhejiang Province, China. Depression, anxiety, insomnia, distress and psychological resilience of participants was assessed and analyzed. RESULTS: A total of 100 participants from 112 aiding Wuhan nurses completed the survey, with a response rate of 89.3%. Another 100 nurses from the same hospitals without aiding Wuhan experience were enrolled as controls. In both groups, a considerable proportion of participants reported symptoms of depression (46.0% for the aiding Wuhan group vs. 49.0% for the controls, similarly hereinafter), anxiety (40.0% vs. 38.0%), and PTSD (61.0% vs. 56.0%). Aiding Wuhan nurses were more likely to suffer from insomnia (41.0% vs. 29.0%, P = 0.041). Multivariable logistic regression analysis showed that aiding Wuhan experience was not associated with depression (adjusted OR (AOR) 0.22; 95%CI, 0.05-1.01), anxiety (AOR 0.53; 95%CI, 0.12-2.43), insomnia (AOR 1.52; 95%CI, 0.76-3.02), PTSD (AOR 0.50; 95%CI, 0.19-1.34), or resilience (AOR 1.59; 95%CI, 0.78-3.26). Resilience was negatively correlated with depression, anxiety, insomnia, and PTSD. CONCLUSIONS: This survey indicated that aiding Wuhan experience a year ago did not cause additional adverse mental health outcomes in nurses, expect for insomnia. The psychological status of nurses in general calls for more attention.

[Qualitative study on working experience of COVID-19 care nurses].

OBJECTIVE: To study the working experience of COVID-19 care nurses. METHODS: Twenty two nurses taking care of COVID-19 patients were interviewed by means of descriptive phenomenology. All the data were transcribed and recorded, and then processed into WORD documents. The Colaizzi 7 footwork was used to classify, encode, establish nodes and extract themes based on Nvivo11.0 software. RESULTS: Two main themes were extracted: one is the positive feelings of nurses, including the sense of professional mission and pride, the sense of achievement and happiness, the improvement of self-worth and ability, the powerful support system and the power of role models; the other is the negative experience of nurses, including the worry and anxiety at work, the lack of experience and trust, the difficulty of work, and the inconvenience of isolating life. CONCLUSIONS: s While fully affirming the work value of nurses, it is necessary for the society, hospitals and patients to give extensive and continuous support, care and respect to nurses, so as to stimulate their working enthusiasm and sense of professional achievement. Hospital managers need to implement all kinds of security work, meet the safety needs of nurses, pay attention to the physical and mental health of nurses, strengthen the training of nursing talents for critical and severe diseases and infectious diseases, improve the allocation of human resources, and enhance the ability of material allocation and reserve for major health events, so as to make adequate preparations for coping with public health events in the future.

Factors Associated With Mental Health Outcomes Among Health Care Workers Exposed to Coronavirus Disease 2019.

Importance: Health care workers exposed to coronavirus disease 2019 (COVID-19) could be psychologically stressed. Objective: To assess the magnitude of mental health outcomes and associated factors among health care workers treating patients exposed to COVID-19 in China. Design, Settings, and Participants: This cross-sectional, survey-based, region-stratified study collected demographic data and mental health measurements from 1257 health care workers in 34 hospitals from January 29, 2020, to February 3, 2020, in China. Health care workers in hospitals equipped with fever clinics or wards for patients with COVID-19 were eligible. Main Outcomes and Measures: The degree of symptoms of depression, anxiety, insomnia, and distress was assessed by the Chinese versions of the 9-item Patient Health Questionnaire, the 7-item Generalized Anxiety Disorder scale, the 7-item Insomnia Severity Index, and the 22-item Impact of Event Scale-Revised, respectively. Multivariable logistic regression analysis was performed to identify factors associated with mental health outcomes. Results: A total of 1257 of 1830 contacted individuals completed the survey, with a participation rate of 68.7%. A total of 813 (64.7%) were aged 26 to 40 years, and 964 (76.7%) were women. Of all participants, 764 (60.8%) were nurses, and 493 (39.2%) were physicians; 760 (60.5%) worked in hospitals in Wuhan, and 522 (41.5%) were frontline health care workers. A considerable proportion of participants reported symptoms of depression (634 [50.4%]), anxiety (560 [44.6%]), insomnia (427 [34.0%]), and distress (899 [71.5%]). Nurses, women, frontline health care workers, and those working in Wuhan, China, reported more severe degrees of all measurements of mental health symptoms than other health care workers (eg, median [IQR] Patient Health Questionnaire scores among physicians vs nurses: 4.0 [1.0-7.0] vs 5.0 [2.0-8.0]; P = .007; median [interquartile range {IQR}] Generalized Anxiety Disorder scale scores among men vs women: 2.0 [0-6.0] vs 4.0 [1.0-7.0]; P < .001; median [IQR] Insomnia Severity Index scores among frontline vs second-line workers: 6.0 [2.0-11.0] vs 4.0 [1.0-8.0]; P < .001; median [IQR] Impact of Event Scale-Revised scores among those in Wuhan vs those in Hubei outside Wuhan and those outside Hubei: 21.0 [8.5-34.5] vs 18.0 [6.0-28.0] in Hubei outside Wuhan and 15.0 [4.0-26.0] outside Hubei; P < .001). Multivariable logistic regression analysis showed participants from outside Hubei province were associated with lower risk of experiencing symptoms of distress compared with those in Wuhan (odds ratio [OR], 0.62; 95% CI, 0.43-0.88; P = .008). Frontline health care workers engaged in direct diagnosis, treatment, and care of patients with COVID-19 were associated with a higher risk of symptoms of depression (OR, 1.52; 95% CI, 1.11-2.09; P = .01), anxiety (OR, 1.57; 95% CI, 1.22-2.02; P < .001), insomnia (OR, 2.97; 95% CI, 1.92-4.60; P < .001), and distress (OR, 1.60; 95% CI, 1.25-2.04; P < .001). Conclusions and Relevance: In this survey of heath care workers in hospitals equipped with fever clinics or wards for patients with COVID-19 in Wuhan and other regions in China, participants reported experiencing psychological burden, especially nurses, women, those in Wuhan, and frontline health care workers directly engaged in the diagnosis, treatment, and care for patients with COVID-19.
