Brief summary
This study evaluates whether the use of a block room (parallel processing model) for regional anaesthesia is associated with improved operating theatre efficiency in orthopaedic surgery. Using routinely collected theatre management system data from a tertiary hospital, patients are classified into three groups based on anaesthetic pathway: block before surgery, theatre block, and no block. The primary outcome is anaesthetic-controlled time, with secondary outcomes including time to readiness for surgery, post-anaesthesia care unit duration, and theatre turnover time. The study is a retrospective observational cohort analysis of cases performed between January 2023 and November 2025. Findings aim to provide contemporary Australian data to inform perioperative workflow optimisation and service planning.
Interventions
This is an observational study evaluating exposure to different anaesthetic workflow pathways in orthopaedic surgery.
Data are collected retrospectively from the Theatre Management System (TMS) at Royal Perth Hospital for cases performed between January 2023 and November 2025.

This is an observational study evaluating exposure to different anaesthetic workflow pathways in orthopaedic surgery. Data are collected retrospectively from the Theatre Management System (TMS) at Royal Perth Hospital for cases performed between January 2023 and November 2025. Participants are classified into three groups based on the timing and location of regional anaesthesia: Block Before Surgery (BBS): Regional anaesthesia performed preoperatively in a block room prior to arrival in the operating theatre. Theatre Block Surgery (TBS): Regional anaesthesia performed after arrival in the operating theatre. No Block Surgery (NBS): No regional anaesthesia performed perioperatively. These groups reflect differences in perioperative workflow and exposure to parallel processing. No intervention is assigned as part of this study. Data are collected retrospectively from routinely recorded theatre management system data for cases performed between January 2023 and November 2025. "This is an observational study evaluating exposure to different anaesthetic workflow pathways in orthopaedic surgery. The primary exposure of interest is the Block Before Surgery (BBS) pathway, in which regional anaesthesia is performed preoperatively in a block room prior to arrival in the operating theatre, enabling parallel processing. Data are collected retrospectively from the Theatre Management System (TMS) at Royal Perth Hospital for cases performed between January 2023 and November 2025. Outcomes observed include anaesthesia-controlled time, theatre turnover time, time from arrival in theatre to patient readiness, and post-anaesthesia care unit (PACU) duration."

Inclusion criteria
Patients undergoing orthopaedic surgery at Royal Perth Hospital between January 2023 and November 2025. Single orthopaedic procedure recorded per surgical episode based on the International Classification of Diseases, 10th Revision, Australian Modification (ICD-10-AM) coding. Procedures restricted to a predefined list where perioperative analgesia can reasonably be provided using regional anaesthesia. Complete and valid theatre timestamp data available for outcome derivation.
Exclusion criteria
Cases with multiple orthopaedic procedure codes recorded for the same surgical episode. Cases not meeting predefined orthopaedic procedure inclusion criteria. Missing, implausible, or internally inconsistent theatre timestamp data. Repeat surgical episodes for the same patient, with only the first eligible case included in the analysis.
