An observational study in Checklist, Teamwork and Information Exchange, sponsored by University of Jena. Completed at 1 site in Germany. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2025-09-24.
Sponsored by University of Jena · Observational
In this study, we designed and evaluated a team timeout checklist (TTOC) which aimed at improving team communication and information exchange before skin incision. The WHO surgical safety checklist was used as a basis with the following changes: we clarified the wording of specific items (e.g., surgical site), we clarified checks by denoting separate items involved for each check, and we denoted circulating nurses as responsible for checklist readout and adherence.
719 studies on the registry are indexed under Communication; 159 are open to participants now.
This study's enrollment of 151 is above the median of 104 across 132 observational studies indexed under Communication.

-
Exclusion Criteria:
teams were observed before and after checklist use
information exchange
this measure assessed whether all sub-items on the TTOC were adequately checked and respective information audibly shared in the team
Time frame: from the time patients were rolled into the OR until skin incision
team communication
using a validate coding scheme, we assessed how team members communicated with each other using professional coding software to log a set of ten behaviors (e.g., instructions, questions, confirmations, speaking up...)
Time frame: from the time patients were rolled into the OR until skin incision
duration of pre skin incision period with and without checklist
to assess how long the period before incision takes with and without TTOC
Time frame: from the time patients were rolled into the OR until skin incision
Ran from Aug 2024 to primary completion in May 2025, 9 months.
Of 51 non-industry observational studies under Communication, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 61. This study's 9 months is below that.
Counting every sponsor, half of 53 studies reached it within 25 months; a quarter within 9 and three quarters within 61.
