A Re-audit of the Management of Diabetic Ketoacidosis (DKA): The Importance of the Seven-Day Working Inpatient Diabetes Specialist Nurse Service.

ABSTRACT

Background Diabetic ketoacidosis (DKA) is a life-threatening metabolic emergency due to insulin deficiency in patients with diabetes mellitus. The United Kingdom national survey and local audits of the management of DKA have revealed several areas of suboptimal care, and room for improvement, necessitating the need for intensified education, updating local guidelines, and increased recruitment of seven-day working inpatient diabetes specialist nurses. Therefore, this project aimed to re-audit our adherence to the DKA treatment guidelines. Methodology A retrospective re-audit examining patient admissions with DKA between October 2022 and September 2023. A list of 18 standards/criteria, adopted from the Joint British Diabetes Society (JBDS) DKA treatment guidelines was used for this re-audit. Results were compared with that of the previous audit. Results We had 126 patients admitted with DKA between October 2022 and September 2023. There were 62 males and 64 females with an average (range) age of 46.5 (19-92) years. Eighty percent had type 1 diabetes, and common precipitating factors for admission included infection and poor adherence to insulin treatment. The median (IQR) length of hospital stay was 2.1 (1.0-5.1) days. Compared to the previous audit, improvements occurred in 11 of 18 standards/criteria. This included timely commencement of intravenous fluids and fixed-rate insulin, commencing glucose infusion to prevent hypoglycemia, potassium replacement, continuation of long-acting insulin during treatment, timely conversion to variable-rate insulin infusion, and conversion to the usual subcutaneous insulin regimen. Additionally, 124 patients (98.4%) were reviewed at least once by the inpatient diabetes specialist nurses (DSN) during their admission. Complications of treatment, namely, iatrogenic hypoglycemia and transient hypokalemia occurred in 13 (10.3%) and 40 (31.7%) patient admissions, respectively. Conclusions This re-audit demonstrated improved adherence to the guidelines during several steps in the management of DKA. It also demonstrated room for improvement regarding other aspects of care. The importance of continued education, accurate documentation, and the presence of seven-day working inpatient DSN cover cannot be overemphasized.
