Abstract

Abstract: To evaluate the clinical benefit of new medicines for type 2 diabetes mellitus (T2DM), the Dutch guideline committee T2DM in primary care established the importance of outcomes and minimal clinically important differences (MCIDs). The present study used an online questionnaire to investigate healthcare professionals' opinions about the importance of outcomes and preferences for MCIDs. A total of 211 physicians, pharmacists, practice nurses, diabetes nurses, nurse practitioners and physician assistants evaluated the importance of mortality, macro‐ and microvascular morbidity, HbA1c, body weight, quality of life, (overall) hospital admissions and severe and other hypoglycemia on a 9‐point scale. All outcomes were considered critical (mean scores 7–9), except for body weight and other hypoglycemia (mean scores 4–6). Only HbA1c and hospital admissions were valued differently by the guideline committee (not critical). Other relevant outcomes according to the respondents were adverse events, ease of use and costs. Median MCIDs were 4 mmol/mol for HbA1c (guideline: 5 mmol/mol) and 3 kg for body weight (guideline: 5 kg weight gain and 2, 5 kg weight loss). Healthcare professionals preferred relative risk reductions of 20% for mortality (guideline: 10%) and macrovascular morbidity (guideline: 25%) and 50% for other hypoglycaemia (guideline: 25%). The MCID of 25% for microvascular morbidity, hospital admissions and severe hypoglycaemia corresponded to the guideline‐MCID. Healthcare professionals' preferences were thus comparable to the views of the guideline committee. However, healthcare professionals had a stricter view on the importance of HbA1c and hospital admissions and the MCIDs for mortality and other hypoglycemia. Abstract : Healthcare professionals' preferences for outcomes and minimal clinically important differences in the evaluation of new type 2 diabetes mellitus (T2DM) medicines were comparable to the views of the Dutch guideline committee T2DM in primary care.
