Design and Evaluation of a Team Timeout Checklist (TTOC) to Improve Information Exchange in the Operating Room Before Skin Incision

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.

Treatment and study plan

Primary outcomes

  1. information exchange

    Time frame: from the time patients were rolled into the OR until skin incision

    this measure assessed whether all sub-items on the TTOC were adequately checked and respective information audibly shared in the team

  2. team communication

    Time frame: from the time patients were rolled into the OR until skin incision

    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...)

Secondary outcomes

  1. duration of pre skin incision period with and without checklist

    Time frame: from the time patients were rolled into the OR until skin incision

    to assess how long the period before incision takes with and without TTOC
