Frailty-Adjusted Inpatient Glycaemic Targets for Preventing Hypoglycaemia: A Quality Improvement Project

Area of Science:

• Geriatrics
• Endocrinology
• Quality Improvement Science

Background:

• Older adults with frailty are at high risk of adverse events from poorly controlled diabetes, including hypoglycemia.
• Current guidelines recommend individualized glucose targets based on frailty, but adherence is inconsistent.
• Hypoglycemia in frail elderly patients can lead to falls, cognitive decline, and increased mortality.

Purpose of the Study:

• To evaluate a quality improvement project aimed at reducing hypoglycemia in frail elderly inpatients with diabetes.
• To improve the setting of individualized glucose targets aligned with patient frailty status.
• To assess the impact of interventions on hypoglycemia incidence and management.

Main Methods:

• A two-cycle quality improvement project was conducted on four elderly-care wards.
• Inclusion criteria: patients aged ≥65 with diabetes experiencing hypoglycemia (<4 mmol/L).
• Interventions included staff education and reinforcement of hypoglycemia management guidelines, with frailty assessment using the Clinical Frailty Scale (CFS).

Main Results:

• Hypoglycemia incidence in elderly inpatients with diabetes decreased by 60% (from 15% to 6%) between cycles.
• Among patients experiencing hypoglycemia, the proportion with frequent episodes (≥3) fell by 10%.
• Correct glucose target documentation improved significantly for patients with CFS 7-9 (25% to 80%) but decreased for CFS 4-6 (56% to 20%).

Conclusions:

• Frailty-adjusted glycaemic targets and proactive medication review effectively reduce hypoglycemia in hospitalized older adults.
• Sustaining these improvements necessitates continuous staff education, standardized care pathways, and clear documentation.
• This approach enhances the safety of diabetes management for vulnerable, frail elderly populations.
