Unspoken Truths: Mental Health Among Academic Surgeons.

OBJECTIVE: To characterize the current state of mental health within the surgical workforce in the United States. BACKGROUND: Mental illness and suicide is a growing concern in the medical community; however, the current state is largely unknown. METHODS: Cross-sectional survey of the academic surgery community assessing mental health, medical error, and suicidal ideation. The odds of suicidal ideation adjusting for sex, prior mental health diagnosis, and validated scales screening for depression, anxiety, post-traumatic stress disorder (PTSD), and alcohol use disorder were assessed. RESULTS: Of 622 participating medical students, trainees, and surgeons (estimated response rate=11.4%-14.0%), 26.1% (141/539) reported a previous mental health diagnosis. In all, 15.9% (83/523) of respondents screened positive for current depression, 18.4% (98/533) for anxiety, 11.0% (56/510) for alcohol use disorder, and 17.3% (36/208) for PTSD. Medical error was associated with depression (30.7% vs. 13.3%, P <0.001), anxiety (31.6% vs. 16.2%, P =0.001), PTSD (12.8% vs. 5.6%, P =0.018), and hazardous alcohol consumption (18.7% vs. 9.7%, P =0.022). Overall, 13.2% (73/551) of respondents reported suicidal ideation in the past year and 9.6% (51/533) in the past 2 weeks. On adjusted analysis, a previous history of a mental health disorder (aOR: 1.97, 95% CI: 1.04-3.65, P =0.033) and screening positive for depression (aOR: 4.30, 95% CI: 2.21-8.29, P <0.001) or PTSD (aOR: 3.93, 95% CI: 1.61-9.44, P =0.002) were associated with increased odds of suicidal ideation over the past 12 months. CONCLUSIONS: Nearly 1 in 7 respondents reported suicidal ideation in the past year. Mental illness and suicidal ideation are significant problems among the surgical workforce in the United States.

Confirmatory Factor Analysis and Measurement Invariance of the Functional Assessment of Cancer Therapy Lung Cancer Utility Index (FACT-LUI).

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-preference-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-preference-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. Highlights: 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-preference-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-preference-based data with less demand on patients, similar to what has been done with some generic instruments.

Music during image-guided breast biopsy reduces patient anxiety levels.

PURPOSE: Interventions to decrease anxiety associated with image-guided breast biopsy are needed. Music intervention has been shown to be helpful in other outpatient procedural settings but data are limited regarding its effectiveness in the setting of breast biopsy. The purpose of this study was to determine whether listening to self-selected music during image-guided breast biopsy lowers anxiety. MATERIALS AND METHODS: 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. RESULTS: Baseline trait anxiety scores in the two groups were similar (34.0 music, 31.5 control, p = .11). Patients in both groups showed lower state anxiety levels after the biopsy (45.6 to 34.3 music, 41.0 to 33.8 control, p < .001 for both). Patients who listened to music showed a greater reduction in anxiety (mean decrease 11.2 music, 7.3 control, p = .03). Post-biopsy anxiety levels were similar to normative values for working women in the same age group. CONCLUSION: Listening to self-selected music reduces anxiety in patients undergoing breast biopsy.

Breast cancer risk, worry, and anxiety: Effect on patient perceptions of false-positive screening results.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: Women with high trait anxiety and family history may particularly benefit from discussions about the risk of recall when choosing a screening regimen.

A Patient-Centered Utility Index for Non-Small Cell Lung Cancer in the United States.

Background. 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. Design. 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. Results. 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 (P = 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. Limitations. 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. Conclusions. The FACT-LUI shows early evidence of validity for informing economic analysis of lung cancer treatments.

Pilot Study of a Patient-Centered Radiology Process Model.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: The RPM shows initial evidence of psychometric validity and internal consistency reliability. Minor changes are anticipated before wider use.

Measurement and Variation in Estimation of Quality of Life Effects of Patients Undergoing Treatment for Papillary Thyroid Carcinoma.

BACKGROUND: Thyroid cancer incidence is increasing. The effect of diagnosis and treatment on health-related quality of life (HRQoL) is an essential variable in the absence of a 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 papillary thyroid cancer (PTC). METHODS: 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 between the four instruments. RESULTS: 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 EQ5D and least with SF6D. Index scores ranged from 0.77 (SF6D) to 0.90 (EQ5D). All scores declined at two weeks postoperatively and returned to pretreatment levels at six months. The SF6D was the only instrument to exceed the conventional minimally important difference between all three time points. Quality-adjusted life-years were as follows: SF6D, 0.79; EQ5D, 0.90; HUI2, 0.88; and HUI3, 0.86. CONCLUSIONS: 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.

Developing a Patient-Centered Radiology Process Model.

PURPOSE: There has been increasing interest in the process of care that patients experience. To keep step with the rest of medicine, our specialty should be designing metrics that assess the overall experience of patients seeking care in radiology departments. A recent memo from the ACR chair calls for more work in this area. The aim of this study was to develop a patient-centered model for the experience of radiologic care, which may be helpful in addressing this need. METHODS: Using principles of multiattribute utility theory and psychometric theory as well as recent literature, a model was developed for a patient-centered index that could be used in radiology facilities. RESULTS: A model was developed that concisely incorporates patient-centeredness of both radiologists and staff members (communication with patient and referrers, competence, and pain control) as well as patient- and process-related issues such as costs, procedural morbidity, access to care, appointment duration, waiting, timing of appointments, cleanliness of facility, and coordination with clinical services. The overall radiology process model was constructed as a set of nested models, which allow more integrated detail within the domains of patient experience. CONCLUSIONS: This model and others like it may help the ACR develop quality metrics to reasonably quantify the patient experience.

Catalog and comparison of societal preferences (utilities) for lung cancer health states: results from the Cancer Care Outcomes Research and Surveillance (CanCORS) study.

BACKGROUND: The EQ-5D and SF-6D are 2 health-related quality-of-life indexes that provide preference-weighted measures for use in cost-effectiveness analyses. METHODS: The National Cancer Institute's Cancer Care Outcomes Research and Surveillance (CanCORS) Consortium included the EQ-5D and SF-12v2 in their survey of newly diagnosed lung cancer patients. Utilities were calculated from patient-provided scores for each domain of the EQ-5D or the SF-6D. Utilities were calculated for categories of cancer type, stage, and treatment. RESULTS: There were 5015 enrolled lung cancer patients with a baseline survey in CanCORS; 2396 (47.8%) completed the EQ-5D, and 2344 (46.7%) also completed the SF-12v2. The mean (standard deviation) utility from the EQ-5D was 0.78 (0.18), and from the SF-6D (derived from SF-12v2) was 0.68 (0.14). The EQ-5D demonstrated a ceiling effect, with 20% of patients reporting perfect scores, translating to a utility of 1.0. No substantial SF-6D floor effects were noted. Utilities increased with age and decreased with stage and comorbidities. Patient-reported (EQ-5D) visual analog scale scores for health status had a moderate (r = 0.48, p < 0.0001) positive correlation with utilities. A subset (n = 1474) completed follow-up EQ-5D questionnaires 11-13 months after diagnosis. Among these patients, there was a nonsignificant decrease in mean utility for stage IV and an increase in mean utility for stages I, II, and III. CONCLUSION: This study generated a catalog of community-weighted utilities applicable to societal-perspective cost-effectiveness analyses of lung cancer interventions and compared utilities based on the EQ-5D and SF-6D. Potential users of these scores should be aware of the limitations and think carefully about their use in specific studies.

Comparing morbidities of testing with a new index: screening colonoscopy versus core-needle breast biopsy.

PURPOSE: Focusing on outcomes of care alone may be too restrictive. Patients can experience morbidity that is important to them from health care processes themselves. However, many processes, such as testing and screening, have been little evaluated. This study's purpose was to assess the construct validity of a new preference-based index, the Testing Morbidities Index (TMI), by comparing two common cancer-related procedures in prior publications: screening colonoscopy and core-needle breast biopsy. METHODS: Women evaluating their breast biopsies (n = 100) were compared with men and women who had undergone screening colonoscopy (n = 109) after both groups completed the TMI. The TMI addresses physical and mental or emotional quality of life affected by test-specific aspects occurring before, during, or after any test. It has 7 domains and survey items. TMI scores can be scaled in various ways, including multi-attribute value theory-based patient or societal preferences, where 0 = dead and 1.0 = full health, as used here. RESULTS: There was significantly greater morbidity from breast biopsy (mean, 0.84) than from screening colonoscopy (mean, 0.88) comparing overall TMI preference scores (P < .0001). Breast biopsy showed significantly worse morbidity (P = .005 to P < .0001) in most domains. Pain or discomfort before testing was worse for colonoscopy because of bowel preparation. The TMI showed no floor effect and an acceptable ceiling effect. CONCLUSIONS: The TMI provides the first objective evidence comparing the morbidity of one cancer-related testing procedure with another. The TMI may be useful in assessments of medical care processes informative to institutions and imaging departments, shared decision-making scenarios, and economic analyses.

MRI-guided focused ultrasound surgery for uterine fibroid treatment: a cost-effectiveness analysis.

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.

Percutaneous breast biopsy: effect on short-term quality of life.

PURPOSE: To examine the effects of percutaneous breast biopsy on short-term quality of life. MATERIALS AND METHODS: The institutional review board approved this HIPAA-compliant prospective study. From December 1, 2007, through February 28, 2010, women undergoing percutaneous breast biopsy in an academic medical center were recruited to participate in a mixed-mode survey 2-4 days after biopsy. Patients described their biopsy experience by using the Testing Morbidities Index (TMI), a validated instrument for assessing short-term quality of life related to diagnostic testing. The scale ranged from 0 (worst possible experience) to 100 (no adverse effects). Seven attributes were assessed: pain or discomfort before and during testing, fear or anxiety before and during testing, embarrassment during testing, and physical and mental function after testing. Demographic and clinical information were also collected. Univariate and multivariate linear regression analyses were performed to identify significant predictors of TMI score. RESULTS: In 188 women (mean age, 51.4 years; range, 22-80 years), the mean TMI score (±standard deviation) was 82 ± 12. Univariate analysis revealed age and race as significant predictors of the TMI score (P < .05). In the multivariate model, only patient age remained a significant independent predictor (P = .001). TMI scores decreased by approximately three points for every decade decrease in patient age, which suggests that younger women were more adversely affected by the biopsy experience. CONCLUSION: Younger patient age is a significant predictor of decreased short-term quality of life related to percutaneous breast biopsy procedures. Tailored prebiopsy counseling may better prepare women for percutaneous biopsy procedures and improve their experience.

Responsiveness of the testing morbidities index in colonoscopy.

OBJECTIVES: 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. METHODS: 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. RESULTS: 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). CONCLUSION: The TMI appears responsive and exhibits further evidence of construct validity.

Patient and societal value functions for the testing morbidities index.

BACKGROUND: We developed preference-based and summated scale scoring for the Testing Morbidities Index (TMI) classification, which addresses short-term effects on quality of life from diagnostic testing before, during, and after testing procedures. METHODS: The two TMI preference functions use multiattribute value techniques; one is patient-based and the other has a societal perspective, informed by 206 breast biopsy patients and 466 (societal) subjects. Because of a lack of standard short-term methods for this application, we used the visual analog scale (VAS). Waiting tradeoff (WTO) tolls provided an additional option for linear transformation of the TMI. We randomized participants to 1 of 3 surveys: The first derived weights for generic testing morbidity attributes and levels of severity with the VAS; a second developed VAS values and WTO tolls for linear transformation of the TMI to a "dead-healthy" scale; the third addressed initial validation in a specific test (breast biopsy). The initial validation included 188 patients and 425 community subjects. Direct VAS and WTO values were compared with the TMI. Alternative TMI scoring as a nonpreference summated scale was included, given evidence of construct and content validity. RESULTS: The patient model can use an additive function, whereas the societal model is multiplicative. Direct VAS and the VAS-scaled TMI were correlated across modeling groups (r = 0.45-0.62). Agreement was comparable to the value function validation of the Health Utilities Index 2. Mean absolute difference (MAD) calculations showed a range of 0.07-0.10 in patients and 0.11-0.17 in subjects. MAD for direct WTO tolls compared with the WTO-scaled TMI varied closely around 1 quality-adjusted life day. CONCLUSIONS: The TMI shows initial promise in measuring short-term testing-related health states.

Patient-centered outcomes in imaging: quantifying value.

The Patient-Centered Outcomes Research Institute was created in response to a mandate to conduct comparative effectiveness research in clinical care to inform decision making. The institute will be funded by the Patient-Centered Outcomes Research Trust Fund, through congressional set-asides, and by Medicare and private health insurers, through a per beneficiary fee. The institute is governed by a board with a broad stakeholder constitution. Key committees set the national agenda for patient-centered outcomes research, the agenda for funding priorities, and communication and dissemination of the evidence with the goal of increasing the rate of implementation of the evidence into policy. In imaging, patient-centered outcomes go beyond the traditional metrics of patient satisfaction. Instead, these outcomes need to encompass the benefits and harms, focus on outcomes relevant to patients, and provide information to inform decision making. Therefore, radiologists need to be involved as stakeholders in the design, conduct, and dissemination of this research.

Quality-of-life assessment of fibroid treatment options and outcomes.

PURPOSE: To obtain utilities (a unit of measure of a person's relative preferences for different health states compared with death or worst possible outcome) for uterine fibroids before and after treatment and to measure short-term utilities for the following uterine fibroid 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 VAS or transformation of VAS. CONCLUSION: Quality of life increased after all fibroid treatments. WTO is feasible for assessing the quality-adjusted morbidity of treatment procedures.

Quality of life implications of bisphosphonate-associated osteonecrosis of the jaw.

PURPOSE: Potentially debilitating, osteonecrosis of the jaw (ONJ) is an emerging complication of bisphosphonates. However, its effect on quality of life (QoL) is unknown. We determined the ONJ-related QoL decline in a cancer patient cohort. PATIENTS AND METHODS: Thirty-four cancer patients with bisphosphonate-associated ONJ completed a telephone survey (October 2007 through May 2008). The Oral Health Impact Profile 14 (OHIP) retrospectively assessed participant oral health-related QoL before and after ONJ. Standardized ONJ descriptions were developed in a multidisciplinary, iterative process and were evaluated with three frequently used preference-based QoL measurement methods on a 0 (death) to 1 (perfect health) scale: Visual Analogue Scale (VAS), Time Trade-Off (TTO), and EQ-5D. RESULTS: ONJ significantly (p < .001) increased OHIP scores (worse QoL) for additive (3.56-16.53) and weighted (7.0-17.5) methods. Seven individual OHIP items significantly increased (Bonferroni correction p < .0035): pain, eating discomfort, self-consciousness, unsatisfactory diet, interrupted meals, irritability, and decreased life satisfaction. Mean preference-based QoL values significantly decreased (p < .001) with worsening ONJ stage (VAS, TTO, and EQ-5D): no ONJ (0.76, 0.86, 0.82), ONJ stage 1 (0.69, 0.82, 0.78), ONJ stage 2 (0.51, 0.67, 0.55), and ONJ stage 3 (0.37, 0.61, 0.32). As ONJ worsened, EQ-5D domain scores significantly increased (p < .001). Pain/discomfort and anxiety/depression contributed most to declining QoL. CONCLUSIONS: ONJ significantly affects QoL, a detriment that increases with worsening ONJ. QoL impairments for ONJ stages 2 and 3 are similar to other treatment side effects that influence decision-making. Bisphosphonate-associated ONJ QoL is an important consideration for patients, clinicians, and policy makers.

Initial development of the Temporary Utilities Index: a multiattribute system for classifying the functional health impact of diagnostic testing.

PURPOSE: The effects of testing and screening on quality of life may influence the future behavior of society, but have not been quantified. We derived a health classification and survey items for the morbidities 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.

Methods for measuring temporary health States for cost-utility analyses.

A variety of methods are available to measure preferences for temporary health states for cost-utility analyses. The objectives of this review were to summarize the available temporary health-state valuation methods, identify advantages and disadvantages of each, and identify areas for future research. We describe the key aspects of each method and summarize advantages and disadvantages of each method in terms of consistency with QALY theory, relevance to temporary health-state-specific domains, ease of use, time preference, and performance in validation studies. Two broad categories of methods were identified: traditional and adapted. Traditional methods were health status instruments, time trade-off (TTO), and the standard gamble (SG). Methods adapted specifically for temporary health-state valuation were TTO with specified duration of the health state, TTO with a lifespan modification, waiting trade-off, chained approaches for TTO and SG, and sleep trade-off. Advantages and disadvantages vary by method and no 'gold standard' method emerged. Selection of a method to value temporary health states will depend on the relative importance of the following considerations: ability to accurately capture the unique characteristics of the temporary health state, level of respondent burden and cognition, theoretical consistency of elicited preference values with the overall purpose of the study, and resources available for study development and data collection. Further research should focus on evaluating validity, reliability and feasibility of temporary health-state valuation methods.

Measuring the quality-of-life effects of diagnostic and screening tests.

Health-related quality of life (HRQL) is a central concept for understanding the outcomes of medical care. When used in cost-effectiveness analysis, HRQL is typically measured for conditions persisting over long time frames (years), and quality-adjusted life year (QALY) values are generated. Consequently, years are the basic unit of time for cost-effectiveness analysis results: dollars spent per QALY gained. However, shorter term components of health care may also affect HRQL, and there is increased interest in measuring and accounting for these events. In radiology, the short-term HRQL effects of screening and diagnostic testing may affect a test's cost-effectiveness, even though they may only last for days. The unique challenge in radiology HRQL assessment is to realistically tap into the testing and screening experience while remaining consistent with QALY theory. The authors review HRQL assessment and highlight methods developed to specifically address the short-term effects of radiologic screening and testing.
