Search ClinicalTrials.gov by intervention and condition, then sweep the WHO ICTRP portal for records from other registries, logging the date and record count for each search so your handoff documents registry coverage. ClinicalTrials.gov lets you filter registered studies by condition, intervention, location, status, study type, dates, and other study fields, so build the drug-and-condition query there first and record the result count. The WHO ICTRP Search Portal provides a single access point for records supplied by participating clinical-trial registries, which is how you reach registrations held outside ClinicalTrials.gov.
- Run the ClinicalTrials.gov search with the drug as the intervention and the target condition as the condition filter; record the date, the exact query terms, and the number of records returned. Expected result: a dated baseline count for the ClinicalTrials.gov portion of the sweep.
- Repeat the same intervention-and-condition terms in the WHO ICTRP Search Portal; record the date and the number of records returned. Expected result: a dated count covering records supplied by other participating registries.
- Compare the two result sets and note which records appear only in the ICTRP results. Expected result: a list of registry records your ClinicalTrials.gov search did not surface, which you carry into the handoff.
- Assemble the handoff with both dated counts, the query terms used, and the list of records unique to each source. Expected result: a registry sweep whose coverage is documented by source, date, and count.
Use the structured registration fields, such as study identification, status, design, eligibility, locations, and outcomes, to describe each record consistently in the handoff. If a record appears in only one source, treat it as unresolved and check the registration directly in the registry that supplied it before the Monday handoff.
