Transitioning from Hospital Insulin to Oral Hypoglycemic Agents at Home

Decision Algorithm Based on HbA1c and Pre-Hospital Treatment

For Type 2 diabetes patients previously on oral agents alone who required insulin during hospitalization, resume their previous oral medications at the same doses after 48 hours if HbA1c is <8% and renal function is adequate, while progressively decreasing and stopping ultra-rapid insulin as glycemic control is achieved 1
The American Diabetes Association recommends arranging follow-up with the treating physician within 1-2 weeks to discuss potential oral hypoglycemic agent dose increases if needed based on the patient's individualized HbA1c target 1
Ensure home nursing support is arranged for initial glucose monitoring for patients with HbA1c <8% 1
For patients with HbA1c 8-9%, continue slow-acting insulin at home, and provide a protocol for insulin dose adaptation 1
For patients with HbA1c >9% or persistent hyperglycemia, do not transition to oral hypoglycemic agents alone, and maintain the basal-bolus insulin scheme 1, 2

Before resuming any oral agents, verify renal function, with creatinine clearance >30 mL/min for all oral hypoglycemic agents and >60 mL/min for metformin 1

For patients with stress hyperglycemia characterized by elevated blood glucose but HbA1c <6.5%, stop insulin progressively as capillary blood glucose normalizes, and measure fasting blood glucose at one month, then annually 1, 2

The American College of Clinical Endocrinologists recommends resuming oral medications 1-2 days before discharge to assess glycemic response before the patient leaves the hospital 4
For patients with poor prior control, discharge on either a basal-bolus insulin regimen or previous oral agents plus 80% of the hospital basal insulin dose 5, 6

Provide comprehensive diabetes self-management education, including understanding of diabetes diagnosis, self-monitoring of blood glucose technique, blood glucose targets, dietary advice, injection technique, and sick-day management 3

Avoid transitioning patients with HbA1c >9% to oral hypoglycemic agents alone, as these patients have demonstrated inadequate control and require continued insulin therapy 1, 2
Monitor for hypoglycemia during transition, particularly when resuming sulfonylureas or glinides 7

For HbA1c <8%, schedule a follow-up with the treating physician at 1 month 1, 2
For HbA1c 8-9%, schedule a diabetologist consultation, which can be distant or via telemedicine 1, 2
For HbA1c >9%, schedule a diabetologist consultation before discharge 1, 2
