Emergency response and the need for collective competence in epidemiological teams.

Objective: To determine the challenges met by, and needs of, the epidemiology emergency response workforce, with the aim of informing the development of a larger survey, by conducting key informant interviews of public health experts. Methods: We defined our study population as public health experts with experience of epidemiology deployment. Using purposive sampling techniques, we applied random number sampling to shortlists of potential interviewees provided by key organizations to obtain 10 study participants; we identified three additional interviewees through snowballing. The same interviewer conducted all key informant interviews during May-August 2019. We thematically analysed de-identified transcripts using a qualitative data analysis computer software package. Findings: Despite our interviewees having a wide range of organizational and field experience, common themes emerged. Interviewees reported a lack of clarity in the definition of an emergency response epidemiologist; the need for a broader range of skills; and inadequate leadership and mentoring in the field. Interviewees identified the lack of interpersonal skills (e.g. communication) and a lack of career progression options as limitations to the effectiveness of emergency response. Conclusion: The epidemiology emergency response workforce is currently not achieving collective competence. The lack of a clear definition of the role must be addressed, and leadership is required to develop teams in which complementary skills are harmonized and those less experienced can be mentored. Epidemiology bodies must consider individual professional accreditation to ensure that the required skills are being achieved, as well as enabling continual professional development.
