ABSTRACT
ObjectiveTo understand the cooperative work and mechanism in the corona virus disease 2019 containment action by the support-to-Hebei epidemiological investigation group formed by five provinces， summarize the existing challenges， and discuss the relevant mechanism， so as to provide evidence for future support actions. MethodsA questionnaire survey was used to investigate the members from five provinces of the support-to-Hebei epidemiological investigation team. The content included basic information， work situation， problems in cooperative work， and suggestions in support mechanisms. ResultsA total of 104 questionnaires were issued， of which 101 valid questionnaires were collected with an effective response rate of 97.12%. The proportions of respondents who participated in the epidemic-related data preparation， case investigation， technical training， supervision of key venues， and specimen collection was 93.07%， 85.15%， 81.19%， 65.35%， and 44.55%， respectively. The respondents believed that information sharing channel of local epidemic situation was blocked （95.05%）， coordination mechanism among local departments was insufficient （84.16%）， communication and coordination mechanism among the dispatch institutions， support team， and local departments was unperfect （84.16%）， management of the dispatch institutions to the support team was relatively loose （79.21%）， dispatch institutions failed to make full use of professional advantages of the support team （72.28%）， and majority of the support team members engaged in a single profession （59.41%）. The respondents suggested that local departments should improve the information sharing mechanism （95.05%）， strengthen communication and coordination among the dispatch institutions， support team， and local departments （92.08%）， and dispatch institutions should clarify the tasks and responsibilities of the support team （91.09%）， formulate cross-regional emergency support plans （87.13%） and evaluation plans of support action （72.28%）. ConclusionIn order to ensure the efficiency and accuracy of future support actions， it is necessary to improve the mechanism of emergency coordination， communication and matching， response procedures， team management， and support evaluation.
