ABSTRACT
AIM: To determine whether outcomes for people with diabetes undergoing elective surgery improve following the introduction of innovations in the peri-operative care pathway. METHODS: Following a baseline audit of 185 people with diabetes listed for elective surgery (July to December 2017) with a length of stay > 24 hours, a number of changes in practice were implemented. These included dissemination of a 'diabetes peri-operative passport' to participants preoperatively, formation of a diabetes surgery working group, recruitment of surgical diabetes champions and the roll-out of surgical diabetes study days. Crucial was recruitment of a diabetes peri-operative nurse, whose role included engaging and educating others and supporting individuals throughout their peri-operative diabetes care. Records of 166 individuals listed for surgery during the implementation period (July to December 2018) were then audited using the same methodology. RESULTS: The availability of a recent HbA1c measurement significantly increased (63% vs 92%; P ≤ 0.001). The mean HbA1c of those seen for optimizations by the diabetes peri-operative nurse significantly decreased [84 mmol/mol (9.8%) vs 62 mmol/mol (7.8%); P ≤ 0.001]. Recurrent hypoglycaemia significantly decreased (7.0% vs 0.6%; P = 0.002) and the mean number of hyperglycaemic events in people experiencing hyperglycaemia almost halved (3.0 vs 1.7; P=0.007). The mean length of hospital stay significantly decreased (4.8 vs 3.3 days; P=0.001) and, crucially, 30-day readmissions did not increase (12% vs 9%; P=0.307). Postoperative complications significantly decreased (28% vs 16%; P=0.008), including a composite of dysglycaemic complications, poor wound healing, wound infection and other infections (12% vs 5.4%; P=0.023). CONCLUSION: The new pathway improved important peri-operative outcomes for people with diabetes undergoing elective surgery with the potential for cost savings. These findings could have important implications for peri-operative care on a wider scale.
