Learning Objective 1: find out how glucometrics can be used as a tool to evaluate the quality of inpatient glycemic control in a general ward
Learning Objective 2: use Glucometrics to bench-mark inpatient diabetes management against other center of excellence for improvement.
Methods: Capillary blood glucose readings from a general medical ward over a two-month period were collected using the hospital Cobas-IT system. The readings were converted into patient-day average values using the glucometrics software developed at Yale University. The readings were benchmarked against the best patient care unit in Yale-New Haven hospital who had achieved 65% of patient-day mean of between 3.9 to 8.3 mmol/L.
Results: A total of 6245 samples were collected over the study period with 324 patient-days. The median patient-day glucose was 7.3 mmol/L. 60.5% of patient-days had glucose readings within our defined target range of 3.9 to 8.3 mmol/L. 3.4 % included hypoglycemia of < 3.9 mmol/L and 6.8% had severe hyperglycemia of > 16.6 mmol/L The median duration of glucose monitoring was 1.3 days and the median number of glucose samples per patient day was 20.
Conclusion: We achieved 60.5% of patient-days with glucose readings within the target range, which is lower than Yale-New Haven figure of 65%. This study demonstrates that we can use Glucometrics to compare inpatient diabetes management across institution. This helps us to benchmark against other center of excellence for improvement.
