SP3.2.18 Reducing the negative appendicectomy rate in children as part of the ‘improving emergency surgery’ quality improvement programme: an assessment of outcomes and balancing measures for unintended consequences
Abstract Aim To describe methodology of the quality improvement programme. To assess outcomes and balancing measures. Methods This paper describes how Kotter’s 8-step improvement model was applied in a District General Hospital. The primary outcome (negative appendicectomy rate) was assessed using GIRFT data over 6 years. Reducing negative appendicectomies might conceivably result in delayed surgery (with a potentially increased incidence of perforated/gangrenous appendicitis), increased length of stay (LOS) and increased readmissions due to delay-related complications. These were assessed by a retrospective audit of appendicectomies performed over the same 8-week period in 2016 and 2019. Results The negative appendicectomy rate in children fell from 16% in 2016-2017 (England average 12%) to 4% in 2017-2018. The improvement was sustained at 6% in 2018-2019 (England average 11%). The incidence of perforated/gangrenous appendicitis decreased by 6% from 23% in 2016 to 16% in 2019. Average LOS decreased from 4 days in 2016 to 3 days in 2019. There was 1 (3%) readmission within 7 days in 2016, and 2 (6%) in 2019. Reasons for readmission were postoperative small bowel obstruction due to omental band adhesion(1) and persistent pain (2). None were caused by delayed operation. Conclusions A sustained improvement in negative appendicectomy rate can be achieved by adopting a systematic quality improvement approach. Against expectations, the reduction in negative appendicectomy rate was associated with a slight decrease in average LOS and reduced frequency of perforated/gangrenous appendicitis. There was no significant increase in readmissions, and none were due to delayed operations.
