Staff risks stratification in preparation for COVID-19 in a tertiary healthcare facility in Nigeria

INTRODUCTION: this report is a documentation of a staff risk stratification programme, undertaken in University of Benin Teaching Hospital, with outcomes, and the actions taken to protect staff. METHODS: an adapted risk stratification tool was circulated to all staff through their respective heads of departments/units. Staff were expected to voluntary assess their health and risk status in the context of COVID-19, using the tool. A central multi-disciplinary screening committee assessed submissions and invited staff who required further evaluation for physical interviews. Respondents were categorized into three risk/exposure groups from lowest to highest - A, B, and C, based on their individual health assessments, occupational exposures, and information obtained from direct interviews. RESULTS: the committee received submissions from 746 staff, representing 19.4% (about a fifth) of the hospital’s 3,840 staff. One hundred and twenty two of these were invited for physical interviews, of whom 88 (72.1%) were categorized as high risk (Category C): pregnancy (53.4%); bronchial asthma (19.3%); hypertension (11.4%); cancer (3.4%) and sickle cell disease (2.3%); fractures and pulmonary tuberculosis (1%, respectively). These staff were recommended for redeployment from areas of high risk exposure to COVID-19. CONCLUSION: a management-driven risk assessment of hospital staff in preparation for the COVID-19 pandemic revealed that a fifth of staff assessed themselves as being vulnerable to adverse outcomes from exposure. It is our hope that similar risk stratification programmes will become standard practice in healthcare facilities during disease outbreaks, especially in Africa.
