Preventing Diabetic Ketoacidosis: Clinical Decisions in Action (On-Demand)-DKA_Continuous_Ketone

Pdf Summary

The document explains newly released expert consensus guidance on continuous ketone monitoring for diabetes, while emphasizing that the technology is still emerging and lacks outcome-trial evidence.<br /><br />Key points:<br />- A four-band ketone vocabulary is now standardized: normal, elevated, high, and urgent high, based on blood beta-hydroxybutyrate.<br />- Action thresholds are:<br />  - <0.6 mmol/L: no ketone-related action needed<br />  - 0.6–1.5: follow sick-day plan, check glucose, insulin delivery, fluids, carbs, and contact care team<br />  - 1.5–3.0: same actions with greater urgency and frequent repeat checks<br />  - ≥3.0: seek immediate emergency care; audible or vibrating alarm required<br />- Clinicians should act on the ketone number itself, not trend arrows.<br />- Below the urgent-high threshold, alarms should be optional and customizable to reduce alarm fatigue.<br /><br />The paper also stresses what is not yet established:<br />- No continuous ketone monitoring device has proven it prevents DKA or improves outcomes.<br />- Accuracy, precision, and regulatory approval vary by product and region.<br />- Consumers may already access some devices that are not FDA or EMA approved.<br />- Capillary ketone testing remains the standard of care, and users should still have a meter, strips, and a written sick-day plan.<br /><br />Groups most likely to benefit first, if future trials show benefit, include:<br />- People with recurrent DKA<br />- SGLT2 inhibitor users<br />- Pregnant patients<br />- Pump or automated insulin delivery users<br />- People on low-carb or ketogenic diets<br />- Patients with CKD, cardiovascular disease, neuropathy, frailty, mental health comorbidity, or limited access to emergency care<br /><br />Overall, the document frames continuous ketone monitoring as promising but not yet proven, and recommends careful patient counseling based on current consensus rather than marketing claims.
