When can a patient with diabetes and a urinary tract infection be discharged from the hospital, considering they have been treated for diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS)?

When to Discharge a Patient with Diabetes and UTI After DKA/HHS Treatment

A patient with diabetes and UTI who was treated for DKA or HHS can be discharged when DKA/HHS has resolved (defined by specific metabolic criteria), the patient is clinically stable, able to eat and drink, successfully transitioned to subcutaneous insulin, and the UTI is adequately treated with an appropriate antibiotic plan. 1

Metabolic Resolution Criteria for DKA/HHS

Before considering discharge, confirm resolution using these specific parameters (though clinical judgment should not delay discharge if patient is otherwise stable): 1

For DKA resolution:

• Glucose <200 mg/dL 1
• Serum bicarbonate ≥15 mmol/L 1
• Venous pH >7.3 1
• Anion gap ≤12 mmol/L 1

For HHS resolution:

• Calculated serum osmolality <315 mOsm/kg 1
• Patient is alert and oriented 1

Clinical Stability Requirements

The patient must meet ALL of the following criteria before discharge: 1

• Hemodynamic stability: Adequate hydration status restored, stable vital signs 1
• Oral intake: Patient is able to eat and drink without nausea or vomiting 1
• Glycemic control: Successfully transitioned from IV to subcutaneous insulin with stable glucose levels 1
• Electrolyte balance: Potassium normalized (4-5 mmol/L), no ongoing electrolyte abnormalities 1
• Mental status: Alert and oriented, able to participate in self-care 1

Critical Insulin Transition Protocol

Do not discharge until the subcutaneous insulin transition is complete and proven effective: 1

• Initiate subcutaneous multidose insulin regimen (basal-bolus) once patient can eat and DKA/HHS is resolving 1
• Continue IV insulin infusion for 2-4 hours AFTER administering subcutaneous basal insulin to prevent rebound hyperglycemia and recurrent ketoacidosis 1
• Document stable glucose control on the subcutaneous regimen before stopping IV insulin 1

UTI Treatment Considerations

The UTI must be adequately addressed before discharge: 2, 3

• Appropriate antibiotic therapy initiated based on culture results (if available) or empiric coverage 2
• Clinical improvement in UTI symptoms (fever resolution, decreased dysuria) 2
• Ensure antibiotic prescription and clear instructions for completion of therapy at home 2, 3
• UTI is a common precipitating cause of DKA (30-50% of cases), so adequate treatment prevents recurrence 3

Mandatory Discharge Requirements

The patient cannot be safely discharged without ALL of the following in place: 1

Medical Stability Checklist:

• Any urgently needed procedures or surgeries completed 1
• Acceptable glycemic control achieved (glucose 150-250 mg/dL range acceptable during transition) 1
• Precipitating cause (UTI) identified and treatment plan established 1, 3

Patient Capability Assessment:

• Patient (or caregiver) demonstrates ability to manage diabetes regimen at discharge location 1
• Patient can perform or has assistance with blood glucose monitoring 1
• Patient understands insulin administration technique 1

Discharge Planning Documentation:

• Diabetes supplies provided: Blood glucose meter, test strips, insulin pens/syringes, needles, and proper disposal containers 1
• Medication reconciliation completed: All home and hospital medications cross-checked, chronic medications not inadvertently stopped 1
• Written discharge plan: Specific insulin regimen, glucose monitoring schedule, sick-day management instructions 1

Required Patient Education Before Discharge

Document that the patient received education on: 1

• Recognition, treatment, and prevention of both hyperglycemia AND hypoglycemia 1
• When to call healthcare provider (specific glucose thresholds, warning signs) 1
• Home glucose monitoring technique and target ranges 1
• Insulin administration timing and technique (if applicable) 1
• Sick-day management to prevent DKA/HHS recurrence 1
• Healthy food choices and meal planning 1
• Proper disposal of sharps and diabetes supplies 1

Mandatory Follow-Up Arrangements

Schedule follow-up BEFORE discharge—do not discharge without confirmed appointments: 1

• Within 1-2 weeks if glycemic medications were changed or glucose control is not optimal at discharge 1
• Within 1 month for all patients who experienced hyperglycemia in hospital 1
• Follow-up should be with primary care, endocrinology, or diabetes care and education specialist 1
• Scheduling appointments prior to discharge significantly increases attendance rates 1

Communication Requirements

Complete these communication tasks before discharge: 1

• Discharge summary transmitted to primary care provider as soon as possible 1
• Summary must include: root cause of hyperglycemia (UTI in this case), DKA/HHS treatment course, complications, recommended ongoing treatments 1
• Clear documentation of discharge diabetes regimen communicated to both patient/caregiver AND outpatient providers 1
• Identification of specific healthcare professionals who will provide diabetes care after discharge 1

Common Pitfalls to Avoid

Critical errors that lead to readmission: 1, 4

• Premature discontinuation of IV insulin: Always overlap with subcutaneous insulin by 2-4 hours 1, 4
• Insufficient subcutaneous insulin dosing: Ensure adequate basal-bolus regimen established, not just correction doses 1, 5
• Discharging before patient can eat: Patient must tolerate oral intake before transition to subcutaneous insulin 1
• Inadequate patient education: Lack of hypoglycemia recognition education is a major cause of adverse events post-discharge 1
• No follow-up scheduled: Patients without pre-scheduled appointments have significantly higher readmission rates 1

Special Considerations for Discharge Insulin Regimen

Tailor the discharge regimen based on admission HbA1c: 1, 6

• HbA1c <7.5-8%: Resume prehospitalization treatment regimen (oral agents and/or insulin) 1
• HbA1c 8-10%: Discharge on oral agents plus basal insulin at 50% of hospital basal dose 1
• HbA1c >10%: Discharge on basal-bolus regimen or combination of preadmission oral agents plus 80% of hospital basal insulin dose 1

Never discharge on sliding scale insulin alone—this results in poor glycemic control and increased complications 5
