OBJECTIVE: To compare patient-reported outcomes and treatment preference between preprandial inhaled insulin and preprandial subcutaneous (SC) insulin in the context of a clinical trial of crossover design with a primary objective of comparing HbA(1C) between groups. RESEARCH DESIGN AND METHODS: Multi-center, randomized, open-label, two-arm crossover trial conducted in the US and Canada with two 12-week periods comparing preference between preprandial human insulin inhalation powder (HIIP; AIR inhaled insulin) and preprandial SC insulin (regular human insulin or insulin lispro) in patients with type 1 diabetes. Patients received HIIP plus insulin glargine during period 1 and SC insulin plus insulin glargine during period 2, or the reverse sequence. MAIN OUTCOME MEASURES: SF-36 Vitality Subscale, Diabetes Symptom Checklist-Revised subscales, Diabetes Treatment Satisfaction Questionnaire, Insulin Delivery System Questionnaire, HIIP-specific questionnaire, preference question. RESULTS: Of 137 patients entered, 119 completed the study (54% female, mean age 40.9 +/- 12.4 years, mean HbA(1C) 8.1 +/- 1.0%). Patients had significantly greater treatment satisfaction and more positive evaluation of their insulin delivery system (easier to control blood sugar, less lifestyle impact) with HIIP than with SC insulin (all p < 0.01). Patients preferring HIIP (80%) were significantly more confident about (p = 0.005) and comfortable with (p = 0.003) using the system than those preferring SC insulin. Results may not be generalizable to all patients with type 1 diabetes. CONCLUSIONS: Some patients desire alternatives to insulin injection. In this study 80% preferred HIIP to injected insulin. Other patients feel more comfortable with familiar insulin delivery. Healthcare providers should help patients find insulin delivery that corresponds to individual preferences.
