Abstract

Aims

To assess the impact of a multifaceted strategy to improve perioperative diabetes care throughout the hospital care pathway.

Methods

We conducted a controlled before-and-after study in six hospitals. The purpose of the strategy was to target four predominant barriers that obstruct optimal care delivery. We provided feedback on baseline indicator performance, developed a multidisciplinary protocol and patient information, and provided professional education. After a 6-month intervention, we determined the performance changes against three outcome indicators and nine process indicators using data on 811 patients with diabetes who underwent major surgery. The progress of the interventions was monitored closely.

Results

Two process indicators improved significantly in the intervention hospitals: the proportion of patients for whom glycaemic control had been evaluated preoperatively increased by 9% (P < 0.002) and the proportion of patients with blood glucose measurements within 1 h after surgery increased by 29% (P < 0.0001). Four other process indicators and all three outcome indicators improved more in the intervention hospitals than in the control hospitals, but the differences were not statistically significant. These included the proportion of patients with all glucose values at 6–10 mmol/l (+3%) and the proportion of patients with hyperglycaemia (−8%). The implementation of the multidisciplinary protocol was still ongoing after the 6-month intervention period.

Conclusions

The multifaceted improvement strategy had a limited impact on the quality of perioperative diabetes care. This study demonstrates the complexity of improving perioperative diabetes care throughout the multiprofessional hospital care pathway.
