Management of Persistent Hyperglycemia with Impaired Renal Function and Non-Healing Wound

Patient Assessment

The American College of Physicians and the American Diabetes Association recommend that patients with persistent hyperglycemia, impaired and worsening renal function, and a non-healing wound should have their glycemic control optimized with a basal-bolus insulin regimen while closely monitoring renal function, as evidenced by a patient presenting with persistent hyperglycemia, impaired and worsening renal function, and a non-healing wound 1, 2
The patient's refusal to follow a diabetic diet is contributing to poor glycemic control, according to the American Diabetes Association 2

The American College of Physicians recommends insulin as the preferred therapy for persistent hyperglycemia in patients with impaired renal function, with a target glucose range of 140-180 mg/dL to balance glycemic control with hypoglycemia risk 3, 2, 6
A basal-bolus insulin regimen is the recommended approach for patients with diabetes and poor glycemic control, especially those with complications such as non-healing wounds, as suggested by the American Diabetes Association and the Endocrine Society 3, 4
The American Diabetes Association recommends continuing basal insulin and adding prandial insulin coverage with rapid-acting insulin before meals to address postprandial hyperglycemia 3, 4

The National Kidney Foundation recommends immediate attention to rising creatinine levels over a short period, with consideration of temporarily reducing or holding diuretic therapy until renal function stabilizes 7
The American Journal of Kidney Diseases suggests monitoring electrolytes closely, particularly potassium levels, given the combination of renal impairment and spironolactone 7

The American College of Physicians recommends implementing a multidisciplinary approach to wound care, including regular wound assessment, appropriate dressing changes, and possible consultation with a wound care specialist, as well as emphasizing the importance of improved glycemic control for wound healing 1
The American Diabetes Association suggests considering referral to a podiatrist or vascular specialist to evaluate peripheral circulation and optimize wound healing conditions 1

The American Diabetes Association recommends continuing education about the impact of diet on glucose control and wound healing, despite patient resistance to a formal diabetic diet, and considering consultation with a dietitian to develop a personalized meal plan 2, 8
The American College of Physicians suggests focusing on consistent carbohydrate intake rather than strict caloric restriction, which may improve insulin dosing accuracy 3

The National Kidney Foundation recommends checking renal function and electrolytes within 3-5 days to assess response to any medication adjustments 7
The American Diabetes Association suggests documenting wound healing progress at each visit and correlating with glycemic control, as well as providing ongoing diabetes education focusing on the relationship between glucose control and wound healing 1, 2, 8

The American Diabetes Association strongly discourages sole reliance on sliding-scale insulin in hospital and outpatient settings, and recommends avoiding aggressive glycemic targets in patients with renal impairment due to increased hypoglycemia risk 9, 6, 7
The American Journal of Kidney Diseases suggests avoiding dismissing patient concerns about diet and instead working collaboratively to find acceptable dietary modifications 8
