ABSTRACT
BACKGROUND: Hyperglycemia is frequently observed in critically ill patients and is linked to increased complications, prolonged ICU stays, and higher mortality. Traditional physician-led insulin management may lack the responsiveness required for optimal glycemic control. In contrast, nurse-led insulin infusion protocols offer a more timely and effective approach in the ICU setting.
AIM: This study evaluated the effectiveness of a nurse-led insulin infusion protocol in managing hyperglycemia among critically ill patients compared to conventional physician-directed care.
METHODS: A quasi-experimental design was implemented in the ICU of Fayoum University Hospital, Egypt, from January to June 2024. A total of 80 adult patients with hyperglycemia were randomly assigned to either a nurse-led insulin infusion protocol group (n = 40) or a standard care group (n = 40). Key outcomes included time to achieve target blood glucose (BG) levels (110-149 mg/dl), frequency of BG monitoring, and ICU length of stay. Data were analyzed using SPSS software.
RESULTS: Patients in the intervention group achieved significantly better glycemic control at all five time points (p < 0.001), with 62.5% reaching target BG levels within 1-2 days compared to 12.5% in the control group. Additionally, 52.5% of intervention patients had ICU stays of 3-4 days, whereas the same proportion in the control group stayed for more than 7 days (p < 0.001). The frequency of BG monitoring was also higher in the intervention group.
CONCLUSION: The nurse-led insulin infusion protocol significantly enhanced glycemic control and reduced ICU stay duration. These findings support integrating nurse-led protocols in ICU settings to improve patient outcomes, ensure timely interventions, and optimize resource utilization.
