RESUMO
Like soldiers, frontline medical staff provide a first line of defense and have played a critical role in responses to the outbreak of coronavirus disease-2019 in December 2019. It is important to acknowledge the considerable pressure placed on frontline medical staff in the face of a new type of coronavirus that is highly infectious and for which no specific treatment is available. Here, we review the various kinds of psychological problems afflicting frontline medical staff who are combatting the severe acute respiratory syndrome epidemic. These include anxiety, insomnia, depression, interpersonal difficulties, and post-traumatic stress disorder syndrome. We further present a summary of countermeasures for alleviating these problems based on our findings. These countermeasures include ensuring the provision of adequate protective gear for frontline medical staff, developing timely and clear guidelines, strengthening social support, and providing clear criteria and additional training, focusing on the choice of frontline medical staff. An understanding of the psychological impacts of an epidemic situation and of relevant countermeasures will contribute to reducing the psychological pressures on frontline medical staff. Consequently, they will be able to cope better with outbreaks of infectious diseases in the future, to reduce the psychological pressure of the front-line medical staff, and to improve the treatment level.
RESUMO
To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.
