We are currently in Phase 3 as of March 22.
|Criteria for Decision-making|
|Basis for Triggering Criteria||Country Transmission Classification* (WHO)||Local Mitigation Measures||Local IRB Directions||Changes to Research|
|Phase 0||Potential, but no immediate threat of spread to local researchers and employees||Imported cases only; Under investigation; or Interrupted transmission
|No institutional closures||No protocol or reporting changes likely||Develop contingency plans|
|Phase 1||Limited number of cases, minimal risk to researchers and subjects. All cases acquired from outside or known sources of infection; no to minimal local cases||Local transmission||Limited institutional closures (e.g. targeted nursing homes and schools)||Protocol or reporting changes or postponement possible||Same as Phase 0
Screen participants for potential infectious risk
Cease sponsor on-site monitoring visits
IRBs will implement triage procedures to prioritize reviews to manage workload
|Phase 2||Moderate to significant risks to researchers or subjects; Disruptions to ability to conduct research; Local community spread; High absenteeism; Sporadic institutional closures||Local transmission or Community transmission||Institutional closures and measures to work from home||Protocol or reporting changes or postponement possible||Same as Phase 1
Defer enrolling new participants except for Tier 1 and limited Tier 2 studies.
Implement tiered procedures for enrollment/research procedures:
Tier 1: allowable*
Tier 2: must be strongly justified*
Tier 3: direct contact should be paused
|Phase 3||Significant risks to researchers or subjects; Massive regional disruption; Widespread institutional closures||Community transmission (where there’s limited ability to relate cases through transmission chains)||Widespread institutional closure (schools, large events, public spaces, businesses) limitations on transport,||Protocol or reporting changes or postponement likely||Same as Phase 2
Tier 1 studies continue without change.
Cease in-person interactions in Tier 2 studies except with IRB approval.
Research activities in Tier 3 must not enroll new participants in studies requiring in-person interaction nor continue to conduct in-person visits. Data collection that does not require in-person participant interaction (e.g. telephone or online) may continue.
International Sites should follow this tiered plan subject to local health authority and local IRB direction.
It is strongly advised that investigators confer with and rely on local partners to ensure appropriate decision-making for your local context.
- Community transmission is evidenced by the inability to relate confirmed cases through chains of transmission for a large number of cases, or by increasing positive tests through sentinel samples (routine systematic testing of respiratory samples from established laboratories).
- Local transmission indicates locations where the source of infection is within the reporting location.
- Imported cases only indicates locations where all cases have been acquired outside the location of reporting.
- Under investigation indicates locations where type of transmission has not been determined for any cases.
- Interrupted transmission indicates locations where interruption of transmission has been demonstrated (details to be determined)
