Diagnostic investigations

HbA1c testing: as per ADA 2024 guidelines, obtain HbA1c testing in all patients with diabetes or hyperglycemia (random blood glucose > 140 mg/dL; > 7.8 mmol/L) admitted to the hospital if no HbA1c test is available from the prior 3 months.

Medical management

General principles
As per ADA 2024 guidelines:
Consult with a specialized diabetes or glucose management team when accessible when caring for hospitalized patients with diabetes (with an existing or new diagnosis) or stress hyperglycemia.
Tailor structured discharge plans to individual patients with diabetes.

Inpatient care

Prevention of hypoglycemia
As per ADA 2024 guidelines:
Review treatment plans and change as necessary to prevent hypoglycemia and recurrent recurrent when a blood glucose value of < 70 mg/dL (> 3.9 mmol/L) is documented.
Adopt a hypoglycemia management protocol and implement it in each hospital or hospital system. Establish a plan for the prevention and treatment of hypoglycemia for each patient. Document episodes of hypoglycemia in the hospital in the electronic record and track for quality assessment and improvement.

Perioperative care

Oral carbohydrate fluids: as per ES 2022 guidelines, avoid administering preoperative carbohydrate-containing oral fluids in adult patients with T1DM, T2DM, or other forms of diabetes undergoing surgical procedures.

Specific circumstances

Pediatric patients: as per SCCM 2024 guidelines, initiate glycemic management protocols and procedures to treat persistent hyperglycemia ≥ 10 mmol/L (180 mg/dL) in critically ill pediatric patients.

Patient education

Patient education: as per ES 2022 guidelines, consider providing inpatient diabetes education as part of a comprehensive diabetes discharge-planning process in adult patients with diabetes hospitalized for a non-critical illness.

Quality improvement

Institutional protocols: as per ADA 2024 guidelines, ensure that institutions implement protocols using validated written or computerized provider order entry sets for the management of dysglycemia in the hospital (including emergency department, ICU and non-ICU wards, gynecology-obstetrics/delivery units, dialysis suites, and behavioral health units) allowing for a personalized approach, including glucose monitoring, insulin and/or noninsulin therapy, hypoglycemia management, diabetes self-management education, nutrition recommendations, and transitions of care.
