As there is no consensus whether persons naïve to the disease under study or patients suffering from the disease provide more appropriate data on utilities [ 15, 19], information was collected from both groups.
Orthodontic treatment has been reported to have no effect on quality of life (Shaw et al., 2007), so a cost-effectiveness analysis (CEA) may be more appropriate than a cost-utility analysis.
This study represents one of the larger analyses undertaken to date comparing the EQ-5D and SF-6D and suggests that the EQ-5D may be the more appropriate technique for measurement of utility values in severe chronic pain.
A 2010 review of the PACIC found conflicting results about its purported 5-factor structure and suggested that a single factor interpretation was more appropriate, raising questions about the utility of its subscales [ 33].
A general population-derived utility is desirable when the utility is needed to inform decisions that allocate societal resources, while a patient-derived utility may be more appropriate when making treatment decisions guided by patient preferences.
In such a case, the QoS level, expressed in terms of average utility, is a more appropriate measure.
Uncertainty is an important factor in many orthopedic procedures and therefore utility scores are more appropriate than value scores in this context.
It introduces the average utility measure, which considers both the length of itemsets and their utilities, and is thus more appropriate in real-world situations.
However, in cases where generic utility instruments may not capture clinically important changes, as has been shown among patients with UI related problems [ 19, 20], disease-specific community-based utility instruments may be considered more appropriate.
Regrettably, this is true; they're like the utilities – water, electricity, gas or, more appropriate, sewage – I suggested here the other day.
