Declaration of interests
• I am a co-investigator on the EPOCH study
Linking audit to quality improvement?
• Definitions
• Healthcare problem = emergency laparotomy
• HQIP Audit = NELA
• Adding value through linked research projects
• Conclusions
Definitions and context
• Clinical audit• ”…a quality improvement process that seeks to
improve patient care and outcomes through systematic review of care against explicit criteria and the implementation of change.”
NICE 2002
Definitions and context
• Emergency Laparotomy• An abdominal surgical procedure performed at
short notice to treat life-threatening intra-abdominal conditions e.g. obstruction or perforation of the bowel
Definitions and context
• ELN = Emergency Laparotomy Network
• NELA = National Emergency Laparotomy Audit
• EPOCH = Enhanced Perioperative Care for High-Risk Patients (clinical trial)
Emergency Laparotomy: 1998-2012
• High incidence of adverse outcome
• Poor supervision
• Low critical care usage
• High cost

• 37 Hospitals returned data• 2 hospitals excluded (< 50% case ascertainment)
• 35 hospitals • > 90% case ascertainment• 1853 patients• 1941 emergency laparotomies• 46 (range 8-184) procedures per hospital

• Organisational audit• Model action plan• Sharing best practice
• Patient audit• Local availability of data• Software added value e.g. run charts
How does audit achieve QI?
How does audit achieve QI?
• Effect of data collection “Hawthorne effect”
• Audit driving QI

EPOCH
Chief Investigator: Prof Rupert PearseQI Lead: Prof Carol Peden
EPOCH background: emergency laparotomy
• Emergency Laparotomy Network & HES data
• ≈ 30,000 cases per year (England and Wales)
• Overall 25% mortality at 90 days
• Variation in 30-day mortality (4 to 31%)
• Variation in delivered care (vs. standards)
EPOCH background: enhanced recovery

EPOCH: objectives
• Can a quality improvement project to implement a care pathway improve 90-day survival for emergency laparotomy?• Integrated ethnographic evaluation• Cost-effectiveness of project• Long-term impact on mortality (via HQIP-NELA)
EPOCH: trial design
• Stepped wedge randomised cluster trial
• Data capture via HQIP-NELA web portal
• Intervention (vs. usual care):• Integrated Care Pathway• Based on RCS-DoH Recommendations• Package of training and support
RCTs and Cluster RCTs
• RCT = randomised controlled trial• Minimisation of confounding (randomisation)• Minimisation of bias (blinding)• A priori analysis plan addressing single question
• RCT: unit of randomisation = patient• Cluster RCT: unit of randomisation = cluster

EPOCH: trial timelines
• December 2013 • Start-up
• March 2014• Trial starts
• April 2014• First cluster ‘activated’
• August 2015 • Final cluster activated
• Mid - Sept 2015• Final patient recruited
EPOCH: patients
• Aged ≥40 years undergoing non-elective open abdominal surgery in acute NHS hospitals
• Exclusions: Gynaecological and trauma laparotomy, Repeat laparotomy, Appendicectomy
EPOCH: integrated care pathway
