abstract = {\<jats:p\> Background. A portion of the Functional Assessment of Cancer Therapy-Lung (FACT-L) instrument contributed to a previously published utility index, the FACT Lung Utility Index or FACT-LUI. Six FACT items representing lung cancer quality of life covered fatigue, pain, dyspnea, cough, anxiety, and depression. Two FACT items had been previously combined by the index authors into one for nausea and/or appetite loss, resulting in 7 final domains. Methods. The objective was to perform measurement invariance testing within a confirmatory factor analysis (CFA) framework to support the feasibility of using the FACT-LUI for non\textendashpreference-based psychometric applications. The original index patients comprised group 1, and similar FACT patient data ( n = 249) from another published study comprised group 2. One 2-factor model and two 1-factor CFA models were evaluated to assess measurement invariance across groups, using varying degrees of item parceling and a small number of residual covariances, all justified by the literature. Results. The 1-factor models were most optimal. A 1-factor model with 1 pair of items parceled showed invariance to the partial scalar level using usual fit criteria across groups, requiring 2 unconstrained intercepts. A 1-factor model with 3 pairs of justified parcels showed full configural, metric, and scalar invariance across groups. Conclusions. The FACT-LUI items fit a partially to fully invariant 1-factor model, suggesting feasibility for non\textendashpreference-based applications. Implications. Results suggest useful incorporation of the FACT-LUI into clinical trials with no substantial increased respondent burden, allowing preference-based and other psychometric applications from the same index items. \</jats:p\>\<jats:sec\>\<jats:title\>Highlights\</jats:title\>\<jats:p\> This work suggests that in addition to being originally designed for use as a utility index, the 7 FACT-LUI items together also fit simple CFA and measurement invariance models. This less expected result indicates that these items as a group are also potentially useful in non\textendashpreference-based applications. Clinical trials can make for challenging decisions concerning which patient-reported outcome measures to include without being burdensome. However, the literature suggests a need for improved reporting of quality of life in lung cancer in particular as well as cancer in general. Inclusion of more disease-specific items such as the FACT-LUI may allow for information gathering of both preference-based and non\textendashpreference-based data with less demand on patients, similar to what has been done with some generic instruments. \</jats:p\>\</jats:sec\>},

abstract = {Background - There is an escalating worldwide population of thyroid cancer survivors. In addition to conventional metrics of quality of care, quality of life (QoL) assessment in thyroid cancer patients is imperative. Thyroid cancer survivors face unique impediments to health-related QoL (HRQoL), including thyroid-specific symptoms and exposure to disease-related stressors-including fear of recurrence and financial toxicity-over a prolonged survival period. Survey instruments currently used to assess HRQoL in TC survivors may be insufficient to accurately capture the burden of disease in this population. We aimed to identify the HRQoL instruments in the literature which have been applied in the thyroid cancer survivor population, and to present the psychometric properties of the scales and indexes that have been used. We hypothesize that few instruments have shown evidence of validity in this population. Summary - Of the 927 articles identified by search criteria, only 28 studies using 15 HRQoL instruments met inclusion criteria. Of the 15 HRQoL instruments identified, 9 were psychometric health status instruments and 6 were preference-based indexes, but none had been validated in the thyroid cancer survivor population. While the majority of reviewed studies demonstrated impaired psychological and emotional well-being in thyroid cancer survivors, these findings were not uniformly demonstrated across studies, and the longevity of the impact of thyroid cancer on HRQoL was variably reported. Conclusions -- Discrepancies in the literature regarding the impact of thyroid cancer survivorship on HRQoL emphasize the challenges of accurately assessing patient perspectives, reinforcing the importance of using well-constructed instruments to measure patient-reported outcomes in the target population. Care providers involved in the treatment of thyroid cancer survivors should be aware of longitudinal effects on HRQoL, especially pertaining to chronic psychological debilitation. Further development and rigorous validation of thyroid cancer-specific instruments will allow for better data gathering and understanding of the barriers to achieving high long-term HRQoL in thyroid cancer survivors throughout their long post-survival treatment course.},

This randomized controlled trial was approved by the institutional review board and was HIPAA-compliant. 157 women between 18 and 75 (mean, 49.7 years) years of age, undergoing stereotactic or ultrasound-guided core biopsy, were enrolled in the study and were prospectively randomized to music or usual care. Patients in the music group listened to music of their choice during the biopsy. All patients completed the State Trait Anxiety Inventory (STAI) before and after the biopsy. Differences in pre-biopsy and post-biopsy anxiety levels were compared between the two groups using the Mann-Whitney U test.

abstract = {The impact of mammography screening recall on quality-of-life (QOL) has been studied in women at average risk for breast cancer, but it is unknown whether these effects differ by breast cancer risk level. We used a vignette-based survey to evaluate how women across the spectrum of breast cancer risk perceive the experience of screening recall. Women participating in mammography or breast MRI screening were recruited to complete a vignette-based survey. Using a numerical rating scale (0-100), women rated QOL for hypothetical scenarios of screening recall, both before and after benign results were known. Lifetime breast cancer risk was calculated using Gail and BRCAPRO risk models. Risk perception, trait anxiety, and breast cancer worry were assessed using validated instruments. The final study cohort included 162 women at low (n = 43, 26%), intermediate (n = 66, 41%), and high-risk (n = 53, 33%). Actual breast cancer risk was not a predictor of QOL for any of the presented scenarios. Across all risk levels, QOL ratings were significantly lower for the period during diagnostic uncertainty compared to after benign results were known (p 0.05). In multivariable regression analyses, breast cancer worry was a significant predictor of decreased QoL for all screening scenarios while awaiting results, including scenarios with non-invasive imaging alone or with biopsy. High trait anxiety and family history predicted lower QOL scores after receipt of benign test results (p 0.05). Women with high trait anxiety and family history may particularly benefit from discussions about the risk of recall when choosing a screening regimen.},

abstract = {A preference-based quality-of-life index for non-small cell lung cancer was developed with a subset of Functional Assessment of Cancer Therapy (FACT)-General (G) and FACT-Lung (L) items, based on clinician input and the literature. A total of 236 non-small cell lung carcinoma patients contributed their preferences, randomly allocated among three survey groups to decrease burden. The FACT-L Utility Index (FACT-LUI) was constructed with two methods: 1) multiattribute utility theory (MAUT), where a visual analog scale (VAS)-based index was transformed to standard gamble (SG); and 2) an unweighted index, where items were summed, normalized to a 0 to 1.0 scale, and the result transformed to a scale length equivalent to the VAS or SG MAUT-based model on a Dead to Full Health scale. Agreement between patients' direct utility and the indexes for current health was assessed. The agreement of the unweighted index with direct SG was superior to the MAUT-based index (intraclass correlation for absolute agreement: 0.60 v. 0.35; mean difference: 0.03 v. 0.19; and mean absolute difference 0.09 v. 0.21, respectively). Mountain plots showed substantial differences, with the unweighted index demonstrating a median bias of 0.02 versus the MAUT model at 0.2. There was a significant difference ( = 0.0002) between early (I-II) and late stage (III-IV) patients, the mean difference for both indexes being greater than distribution-based estimates of minimal important difference. The population was limited to non-small cell lung cancer patients. However, most quality-of-life literature consulted and the FACT instruments do not differentiate between lung cancer cell types. Minorities were also limited in this sample. The FACT-LUI shows early evidence of validity for informing economic analysis of lung cancer treatments.},

abstract = {The Radiology Process Model (RPM) was previously described in terms of its conceptual basis and proposed survey items. The current study describes the first pilot application of the RPM in the field and the results of initial psychometric analysis. We used an Institutional Review Board-approved pilot RPM survey in 100 patients having outpatient interventional radiology procedures. The 24 survey items had 4 or 5 levels of severity. We assessed for missing data, items that patients found confusing, any suggestions by patients for additional items and clarity of items from patient feedback. Factor analysis was performed and internal consistency measured. Construct validity was assessed by correlation of patient responses to the items as a summated scale with a visual analog scale (VAS) they completed indicating their interventional radiology experience. The visual analog scale and the RPM summated scale were strongly correlated (r = 0.7). Factor analysis showed four factors: interactions with facility and doctors/staff, time-sensitive aspects, pain, and anxiety. The items showed high internal consistency (alpha: 0.86) as a group and approximately 0.7 to 0.9 by the factors. Analysis shows that two items could be deleted (cost and communication between radiologist and referrers). Revision of two items and potential addition of others are discussed. The RPM shows initial evidence of psychometric validity and internal consistency reliability. Minor changes are anticipated before wider use.},

abstract = {Thyroid cancer incidence is increasing. The effect of diagnosis and treatment on health related quality of life (HRQoL) is an essential variable given no change in life span for the majority of patients. HRQoL instruments, with data useful for between-disease comparisons, are being increasingly used for health policy and outcomes evaluation. Variation exits among the instruments based on the impact of a specific disease. We assessed which of four well-validated preference-based surveys detect changes in health and clinical intervention in patients diagnosed with the papillary thyroid cancer (PTC). Four commonly used HRQoL questionnaires (Short Form-12v2® (SF6D), EuroQol-5D (EQ5D), and Health Utilities Index Mark 2 and 3 (HUI2, HUI3) were administered to patients with the diagnosis of PTC at three perioperative time points during the first year of treatment. Clinicopathological and treatment course data were assessed for HRQoL impact including complications from surgery, re-operation for persistence/early recurrence, and adjuvant radioactive iodine treatment. We compared standard metrics, including ceiling effect, intraclass correlation coefficient, effect sizes, and quality-adjusted life-years (QALYs) among the four instruments. Of 117 patients, 27% had a preoperative diagnosis of anxiety or depression, 41% had regional lymph node metastases, three had distant metastases and 49% underwent adjuvant radioactive iodine treatment. The ceiling effect (i.e. proportion with a perfect score) was greatest with the EQ5D and least with the SF6D. Index scores ranged from 0.77 (SF6D) to 0.90 (EQ5D). All scores declined at 2 weeks' post-op, and returned to pretreatment at six-months. The SF6D was the only instrument to exceed the conventional minimal-important difference between all three time points. QALYs were as follows: SF6D - 0.79, EQ5D - 0.90, HUI2 - 0.88, HUI3 - 0.86. Our results reflect the general good health of PTC patients. The effect on quality of life is primarily related to emotional and social impacts of treatment. The results support the measurement of a similar underlying construct, although variation in detecting changes in health exists between the instruments. Of the instruments assessed, the SF6D is the most responsive to treatment effects and should be utilized in future economic analyses in this patient population.},

The overall radiology process model was constructed as a set of nested models, which allow more integrated detail within the domains of patient experience.This model and others like it may help the ACR develop quality metrics to reasonably quantify the patient experience.},

abstract = {OBJECTIVE. The purpose of this article is to evaluate the cost effectiveness
of a treatment strategy for symptomatic uterine fibroids that uses
MRI-guided focused ultrasound as a first-line therapy relative to
uterine artery embolization (UAE) or hysterectomy. MATERIALS AND
METHODS. We developed a decision-analytic model to compare the cost
effectiveness of three first-line treatment strategies: MRI-guided
focused ultrasound, UAE, and hysterectomy. Treatment-specific short-
and long-term utilities, lifetime costs, and quality-adjusted life
years (QALYs) were incorporated, allowing us to conduct an incremental
cost-effectiveness analysis, using a societal willingness-to-pay
(WTP) threshold of $50,000/QALY to designate a strategy as cost effective.
Sensitivity analyses were subsequently performed on all key parameters.
RESULTS. In the base-case analysis, UAE as a first-line treatment
of symptomatic fibroids was the most effective and expensive strategy
(22.75 QALYs; $22,968), followed by MRI-guided focused ultrasound
(22.73 QALYs; $20,252) and hysterectomy (22.54 QALYs; $11,253). MRI-guided
focused ultrasound was cost effective relative to hysterectomy, with
an associated incremental cost-effectiveness ratio (ICER) of $47,891/QALY.
The ICER of UAE relative to MRI-guided focused ultrasound was $234,565/QALY,
exceeding the WTP threshold of $50,000/QALY, therefore rendering
MRI-guided focused ultrasound also cost effective relative to UAE.
In sensitivity analyses, results were robust to changes in most parameters
but were sensitive to changes in probabilities of recurrence, symptom
relief, and quality-of-life measures. CONCLUSION. First-line treatment
of eligible women with MRI-guided focused ultra-sound is a cost-effective
noninvasive strategy. For those not eligible for MRI-guided focused
ultra-sound, UAE remains a cost-effective option. These recommendations
integrate both the short- and long-term decrements in quality of
life associated with the specific treatment modalities.},

abstract = {The Testing Morbidities Index (TMI) was developed to measure the effects of any diagnostic or screening procedure on health-related quality of life (HRQOL); it includes seven domains incorporating mental and physical aspects before, during, and after testing. To add to prior work on the validity of the TMI classification, responsiveness of a summated scale version was evaluated in 71 colonoscopy patients. Further data on construct validity were also obtained.Patients enrolled in the study when scheduling colonoscopy days to weeks beforehand. The baseline survey included the EuroQol five-dimensional (EQ-5D) questionnaire with five levels in each attribute (EQ-5D-5L questionnaire) and its visual analogue scale (VAS) assessment (EQ-VAS), the Short Form 12 version 2 (SF-12v2) component summary scores and six-dimensional health state short-form (derived from the short-form 12v2 health survey [SF-6D] utilities), and an original construct-specific VAS (CS-VAS) for usual HRQOL using utility scale anchors. The TMI's highest possible summated score (all best levels) served as its baseline. Survey data were generally obtained by telephone interview. A postprocedure survey was given to patients after colonoscopy and interviews conducted as soon as possible after the day of the procedure. The postprocedure survey included the SF-12v2/SF-6D, EQ-5D questionnaire instruments, TMI items, and a CS-VAS incorporating the overall HRQOL effects of colonoscopy.Standardized response means showed greatest responsiveness by the TMI (-1.52) followed by the CS-VAS instruments (-0.42). The EQ-5D-5L questionnaire, the EQ-VAS, and the SF-12 component summaries were unresponsive, and the SF-6D was minimally responsive (-0.05). Correlation of the post-CS-VAS with the TMI was substantial (r = -0.52), suggesting TMI construct validity. Moderate to strong correlation of the baseline CS-VAS with standard indexes was observed (r = 0.54-0.81).The TMI appears responsive and exhibits further evidence of construct validity.},

For oral health complications, however, the validity of oral-health specific and generic health-related quality-of-life (QoL) instruments is unknown for cancer patients. This study evaluates the performance, measurement, and prediction characteristics of the Oral Health Impact Profile (OHIP-14) and EQ-5D in cancer patients with bisphosphonate-associated Osteonecrosis of the Jaw (ONJ). 34 cancer patients assessed the QoL of their own ONJ with the OHIP-14 and evaluated the QoL of 4 standardized ONJ Health States with the EQ-5D, as previously published. For each instrument, the standard response mean (SRM), effect size (ES), and ability to distinguish minimally important differences (MID) were evaluated for ONJ compared to baseline (longitudinal responsiveness). Instrument MIDs (cross-sectional responsiveness) were also calculated. Performance of a published general dentistry algorithm to predict EQ-5D values from OHIP-14 results was tested. The OHIP-14 and EQ-5D instruments demonstrated moderate to large longitudinal and cross-sectional responsiveness. Pain was one of the most responsive domains for both instruments. Ceiling/floor effects were most prominent for OHIP-14. A general dentistry algorithm did not adequately predict EQ-5D values for cancer patients. This study provides the first empirical evidence for the performance, measurement, and prediction characteristics of oral-health specific and generic QoL instruments for the oral health side effects of systemic cancer treatment. Instrument validity is supported for oral health complications in cancer patients. These results provide benchmarks for PROs at the intersection of oral medicine and surgery, dentistry, and oncology.

treatments: abdominal hysterectomy, magnetic resonance (MR) imaging-guided
focused ultrasound surgery, and uterine artery embolization (UAE).
MATERIALS AND METHODS: This retrospective study was approved by the
institutional review board and was HIPAA compliant. The waiting trade-off
(WTO) method, a variation on the time trade-off (TTO) method, is
used to obtain utilities for diagnostic procedures on the basis of
the fact that people wait longer to avoid noxious tests and/or procedures.
The WTO method provides short-term quality of life tolls in terms
of quality-adjusted life-weeks by scaling wait times with pre- and
posttreatment utilities. Utilities for uterine fibroids before and
after treatment were obtained with the TTO method and a visual analog
scale (VAS) by using a questionnaire administered by means of a phone
interview. WTO wait times were adjusted for quality of life with
VAS and TTO utilities and a transformation of VAS. Wait times were
compared by using nonparametric tests. The study participants included
62 patients who had undergone abdominal hysterectomy, 74 who had
undergone UAE, and 61 who had undergone MR imaging-guided focused
ultrasound surgery. RESULTS: Quality of life increased with all treatments.
The median WTO wait time was higher for hysterectomy (21.6 weeks)
than for UAE or MR imaging-guided focused ultrasound surgery (14.1
weeks for both) (P \< .05). Quality-adjusted life-week tolls were
smaller when scaled according to TTO than when scaled according to

of testing and screening, to be the foundation of a multiattribute
utility instrument, the Temporary Utilities Index. METHODS: Seventy-six
women ranked the importance of attributes of the testing process
after breast biopsy. Seven survey items on the testing process were
subsequently developed and assessed for clarity by a second group
of 19 patients. The items cover attributes of mental and physical
well-being before, during, and after testing. A survey panel of 164
subjects accessed online used the items to endorse expected and experienced
effects of colon screening and mammography. They also endorsed items
from a colorectal benefits and barriers scale, a risk perception
scale, and EQ-5D, to utilize in the analyses of validity of the TUI
items. RESULTS: Based on criteria from the literature and limited
psychometric analysis, the items showed evidence of practicality,
validity, and a strong association with barriers. CONCLUSIONS: The
TUI health classification and survey items show evidence of validity,
and may inform economic analysis, once combined with utility weights.},

abstract = {To determine if radiology residents who used a structured reporting system (SRS) produced higher quality reports than residents who used conventional free-text dictation to report cranial magnetic resonance (MR) imaging in patients suspected of having a stroke. The study was approved by an institutional review board and was HIPAA compliant; informed consent was obtained. This study included residents, with 16 in the control group and 18 in the intervention group. For phase 1, each subject reviewed the same set of 25 brain MR imaging cases and dictated the cases by using free-text conventional dictation. For phase 2, 4 months later, the control group repeated the same process, whereas the intervention group reread the same MR imaging cases by using SRS to create reports. Resident-generated reports were graded for accuracy and completeness by a neuroradiologist on the basis of consensus interpretations and criterion standard diagnoses as established with at least 6 months of clinical follow-up, imaging follow-up, and/or histologic examination where appropriate. Accuracy and completeness scores were analyzed by using a Wilcoxon signed rank test for paired data and a Mann-Whitney U test for nonpaired data. Intervention group residents were surveyed regarding their opinions of SRS. For phase 1 reports, no significant difference in accuracy or completeness scores between control and intervention groups was found. Decreases in accuracy (91.5 to 88.7) and completeness (68.7 to 54.3) scores for phase 2 compared with phase 1 for the intervention group were found; increases in accuracy (91.4 to 92.4) and completeness (67.8 to 71.7) scores for phase 2 compared with phase 1 for the control group were found (all P values \< .001). The most common complaints were that the SRS was overly constraining with regard to report content and was time-consuming to use. While there are many potential benefits of structuring radiology reports, such changes cannot be assumed to improve report accuracy or completeness. Any SRS should be tested for effect on intrinsic report quality.},

The US Task Force on Organ Transplantation recommended that considerations

three types of need, related to age, clinical urgency, and quality

were asked to choose between two hypothetical patients who differed
in clinical urgency (time to death textless1 year), age, pretransplant
and post-transplant quality of life, and life expectancy. RESULTS:
A pool of 1600 people were notified via email about the survey; 623
(39 responded. Respondents preferred giving organs to younger people
up to an age difference of textless15.4 years (SD 18) and more clinically
urgent people up to a difference in urgency of textless2.54 months

patient and the relative status of the patients. If both had worse
than average quality of life, respondents preferred the better-off
patient. When both had better than average quality of life, they
preferred the worse-off patient. In analysis according to age versus
clinical urgency, the older the patient, the more urgency needed
to receive priority. In quality of life versus clinical urgency,
the better the control's quality of life, the more urgency the competing
patient required. The worse the patient's post-transplant outcome,
the more urgency needed to receive priority. CONCLUSIONS: It appears
that clinical urgency is only one of many factors influencing attitudes
about allocation decisions and that respondents may invoke different

test can influence its cost-effectiveness, but the quantification
of that morbidity is controversial. Accounting for pain and invasiveness
requires the measurement of "process utility" in addition to the
expected value of testing. An original time trade-off variant was
applied to the imaging evaluation of cerebrovascular disease, for
which differences in morbidity are important to patients. MATERIALS
AND METHODS: A "waiting trade-off" (WTO) was used to evaluate the
preferences of 89 patients for magnetic resonance (MR) angiography
and conventional x-ray angiography. Patients were experienced with
both tests. A weighted difference was calculated between the period
a patient was willing to wait for a test result and treatment after
a hypothetical "ideal" test and the choice to undergo conventional
angiography or MR angiography with immediate treatment. A rating
scale was used to check the convergent validity of the WTO. RESULTS: Paired data showed a highly significant difference (P = .0001) between
the mean preference for conventional and MR angiography, favoring
the latter and translating into a difference of 5 quality-adjusted
life days. The more negatively patients judged their conventional
angiographic experience, the longer they were willing to wait for
the ideal test result. CONCLUSION: The WTO provides a reasonable
estimate of the relative morbidity of more invasive conventional
angiographic procedures and provides a quality-adjustment term for
economic analysis. Such an approach may enable more complete evaluation
