After application of the bonding agent to the assigned groups of teeth (SWB,
QWB) and the appropriate FS, the teeth were stored in distilled water for 24 hours.
The
QWB is calibrated with a San Diego survey conducted in the early 1970s.
The committee urged the commission to modify the Kaplan
QWB public survey instrument to include more symptoms associated with mental illness, while at the same time pressing for all due speed in collecting the data for mental health.
Two experienced primary care physicians used the
QWB to rate the utilities of the various outcome states in the tree.
Priority is based partially upon a highly technical and somewhat abstract calculation of how each relates to quality of well-being (
QWB) associated with the nature of the condition and the quality of life resulting from providing or denying treatment.(18) Specifically, Oregon adopted an approach called "quality-adjusted life year" (QALY) that incorporates both the quality of life and the effect on life expectancy from treating particular conditions.(19)
The key section of the survey consisted of thirty-one hypothetical health outcomes, which respondents were asked to rate on a Quality of Well Being (
QWB) scale from 0 ("as bad as death") to 100 ("the situation describes good health").
In fact, however, economic considerations had little or nothing to do with placement of this (or any other) treatment on the final list; rather, like most items near the bottom of the list, treatment of extremely premature infants was rated low because it had been assigned to the lowest-ranked service category: treatments offering "minimal or no improvement in
QWB," or Quality of Well-Being, the OHSC's term for quality of life.
