THUMB: Multi-centre Cluster Trial for Caesarean Section Haemorrhage
Sponsor: Bruce Biccard
Summary
The quality improvement project evaluating the delivery of a perioperative care complex intervention to improve haemorrhage-related outcomes in patients undergoing caesarean section. The objectives of the current study will be: 1. To evaluate whether implementation of the 'Rule of THUMB' perioperative complex intervention increases risk assessment, diagnosis and compliance with proven interventions for haemorrhage during and after caesarean section. 2. To understand the influence of contextual and socio-dynamic factors on how the trial results were achieved and how the intervention mechanisms did, or did not, work in practice (the process evaluation). The findings from this study will be used subsequently to modify and improve the quality improvement intervention, so that it can be delivered at scale across Africa and assess its impact on haemorrhage during and after caesarean section in the future.

Quality improvement program
The intervention comprises two mandatory risk assessments (preoperatively in theatre and postoperatively prior to discharge from the recovery area) which are linked to hospital-specific responses. Assessments for bleeding will occur intraoperatively (through direct vision, haemodynamic changes and/or measurement of blood loss) and postoperatively (with the use of the rapid assessment tool). If bleeding is diagnosed at any point, the THUMB checklist will be used to activate bundled care. On discharge from recovery, high-risk patients will be scheduled to receive a postoperative ward visit within four hours, when a further assessment for bleeding will occur.
