Thuis heb ik nog een ansichtkaart Waarop een kerk een kar met paard Een slagerij J. van der Ven Een kroeg, een juffrouw op de fiets Het zegt u hoogstwaarschijnlijk niets Maar het is waar ik geboren ben Dit dorp, ik weet nog hoe het was De boerenkind'ren in de klas Een kar die ratelt op de keien Het raadhuis met een pomp ervoor Een zandweg tussen koren door Het vee, de boerderijen En langs het tuinpad van m'n vader Zag ik de hoge bomen staan Ik was een kind en wist niet beter Dan dat 't nooit voorbij zou gaan

Patient-adjusted dosing algorithm vs physician standard of care: 26-week RCT Insulin detemir was started once daily as add-on therapy to any other glucose-lowering regimens or as a replacement for prestudy basal insulin • Insulin dose adjustments* – 303 algorithm sites: patients to adjust dose every 3 days based on mean FPG values, n=2787 FPG (mg/dL)
Basal dose adjustment
<80
Reduce detemir dose by 3 U
80–110 >110
Personal feedback to HCP
Summary • There are many issues contributing to inertia, and consequently many potential solutions • Inertia surrounding insulin initiation and intensification is apparent from clinical trials and real-life practice • Improving education of physicians and patients may address current barriers
No change Increase detemir dose by 3 U
– Standard-of-care sites: physician to adjust dose based on standard of care, n=2817 * Insulin detemir dose titration was not enforced in either group Kunt, Snoek. Int J Clin Pract 2009;63(Suppl. 164):6–10
