Health State Utilities for Childhood Attention-Deficit/Hyperactivity Disorder Based on Parent Preferences in the United Kingdom

Abstract

This UK-based study suggests that parent SG interviews are a valid method for obtaining utilities for child ADHD-related health states. The utilities obtained in this study would be appropriate for use in a cost-utility analysis evaluating the costs and benefits of childhood ADHD treatments in the United Kingdom.

Utilities and disutilities for attributes of injectable treatments for type 2 diabetes

“…This duration was evaluated in the pilot study described below, and patients reported no difficulties. The health state duration of 1 month has consistently been found to be acceptable to patients in previous utility studies [7,[43][44][45]. As the health states were being developed, drafts were presented to a physician who is an endocrinologist and diabetes specialist.…”

“…The utility interview procedures have been established in many previous studies that assessed patient preferences Diabetes injection utilities 221 relating to medical conditions [7,41,[43][44][45][46]. The first step was a visual analog scale (VAS) exercise intended to familiarize the patients with the health states.…”

“…Death may not be an effective lower anchor for all health states, however, because participants may be reluctant to gamble with death when the health states describe mild medical conditions. Thus, to discriminate among health states in the high range of the utility scale, it is often necessary to use a temporary health state approach [4,7,[43][44][45][47][48][49][50][51][52]. In this approach, the health states are framed in terms of a specific duration (e.g., 1 month in the current study), with the lower anchor of 0 corresponding to a ''worst'' health state instead of death.…”

“…Finally, patients rated the worst health state so that the raw SG scores could be adjusted onto a chronic scale ranging from death (0) to perfect health (1), following a previously established procedure occasionally referred to as ''chaining'' [4,7,[43][44][45][50][51][52][53]. Patients were asked to choose between living in the worst health state for their entire lifetime or accepting a gamble between death and having perfect health for their entire lifetime.…”

“…This duration was evaluated as part of the pilot study described below, and patients reported no difficulties. The health state duration of 1 month has also been used in several previous utility studies, and it has consistently been found to be acceptable to patients [45][46][47].…”
