The 2014 Ebola outbreak highlighted biosafety gaps. Funding improved public health laboratories (PHLs) and clinical partners' safety practices, though clinical settings require more attention.
Area of Science:
- Public Health
- Laboratory Science
- Infectious Disease Control
Background:
- The 2014 Ebola outbreak exposed significant biosafety vulnerabilities within US health systems.
- Public health laboratories (PHLs) and sentinel clinical laboratories play a critical role in managing infectious disease threats.
Purpose of the Study:
- To evaluate the impact of a $24.1 million funding initiative aimed at enhancing biosafety practices in PHLs and associated clinical laboratories.
- To assess improvements in risk assessment policies and staff certifications for handling highly infectious diseases.
Main Methods:
- A descriptive statistical analysis was conducted using 9 indicators to evaluate 59 PHLs and 4,040 clinical laboratories over 6 reporting periods (March 2015–April 2018).
- Data collection focused on risk assessments, policy implementation, and staff certifications for packaging and shipping hazardous materials.
Main Results:
- By April 2018, 92% of PHLs had conducted Ebola risk assessments, and policy adoption for risk assessments increased from 52% to 91%.
- Clinical laboratory awardee performance improved, with meeting targets for staff certifications rising from 32% to 46%, and risk assessment policies from 18% to 28%.
- Ebola treatment centers showed improved risk assessment policy implementation, increasing from 48% to 67%.
Conclusions:
- Public health laboratories and clinical partners demonstrated progress in biosafety practices and managing biological threats.
- Continued support for biosafety initiatives is crucial for sustained improvement.
- Specific attention and resources are needed to address persistent gaps within the clinical laboratory community.
