BackgroundPatient-centered care is respectful to a patient's preference. All prior clinical trials on patient self-titration algorithms for basal insulin were decided by physicians. We hypothesized that patients and physicians have different preferences.Patients And MethodsPhysicians and diabetes patients were asked to choose their preferred insulin glargine self-titration algorithm among 5 algorithms. Algorithm 1, 1 U increase once daily; algorithm 2, 2 U increase every 3 days; algorithm 3, 3 U increase every 3 days; algorithm 4, titration every 3 days according to fasting blood glucose, and algorithm 5, weekly titration 2-8 U based on 3-day mean fasting blood glucose levels.ResultsEleven (5.2%) out of 210 physicians and 180 (90.9%) out of 198 patients preferred algorithm 1 (χ2=300.4, p=0.000). In contrast, 195 (92.9%) physicians and 18 (9.1%) patients preferred algorithm 2 (χ2=286.6, p=0.000). In addition, 4 (1.9%) physicians but no patients preferred algorithm 3 (χ2=2.099, p=0.124). Neither physicians nor patients chose algorithms 4 or 5. Most physicians preferred algorithm 2 since it is recommended by guidelines, but most patients preferred algorithm 1 for its simplicity.ConclusionPatients had different preferences compared with physicians. Attention should be given to patients' preferences to increase adherence and improve glycemic control.
