Effects of patient-reported outcome assessment order.

BACKGROUND: In clinical trials and clinical practice, patient-reported outcomes are almost always assessed using multiple patient-reported outcome measures at the same time. This raises concerns about whether patient responses are affected by the order in which the patient-reported outcome measures are administered. METHODS: This questionnaire-based study of order effects included adult cancer patients from five cancer centers. Patients were randomly assigned to complete questionnaires via paper booklets, interactive voice response system, or tablet web survey. Linear Analogue Self-Assessment, Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events, and Patient-Reported Outcomes Measurement Information System assessment tools were each used to measure general health, physical function, social function, emotional distress/anxiety, emotional distress/depression, fatigue, sleep, and pain. The order in which the three tools, and domains within tools, were presented to patients was randomized. Rates of missing data, scale scores, and Cronbach's alpha coefficients were compared by the order in which they were assessed. Analyses included Cochran-Armitage trend tests and mixed models adjusted for performance score, age, sex, cancer type, and curative intent. RESULTS: A total of 1830 patients provided baseline patient-reported outcome assessments. There were no significant trends in rates of missing values by whether a scale was assessed earlier or later. The largest order effect for scale scores was due to a large mean score at one assessment time point. The largest difference in Cronbach's alpha between the versions for the Patient-Reported Outcomes Measurement Information System scales was 0.106. CONCLUSION: The well-being of a cancer patient has many different aspects such as pain, fatigue, depression, and anxiety. These are assessed using a variety of surveys often collected at the same time. This study shows that the order in which the different aspects are collected from the patient is not important.

Optimizing brief, focused assessment of priority symptoms and concerns in recurrent and/or metastatic squamous cell carcinoma of the head and neck: Content validation of the Functional Assessment of Cancer Therapy/National Comprehensive Cancer Network Head and Neck Symptom Index-10 (FHNSI-10).

BACKGROUND AND AIMS: Patients with recurrent and/or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN) experience vast disease and treatment burdens. Brief, focused instruments are needed to assess patient-reported priority symptoms and concerns as targeted outcome assessments for use in clinical research. Although the instrument was developed based on expert and patient input and is psychometrically valid, the Functional Assessment of Cancer Therapy (FACT)/National Comprehensive Cancer Network (NCCN) Head and Neck Symptom Index-10 (FHNSI-10) has yet to undergo content validation from the perspective of R/M SCCHN patients to evaluate its use as a brief symptom-focused targeted endpoint assessment for use in clinical research. METHODS: Interviews conducted with R/M SCCHN patients explored priority symptoms and concerns, followed by cognitive debriefing of the FHNSI-10 to evaluate face validity. Transcripts were analyzed, and results were mapped to the FHNSI-10. In accordance with published recommendations, expert input from the original development and published literature was considered for content validity assessment. RESULTS: A total of 18 patients participated in a concept elicitation interview; saturation was obtained at interview 17. Most (83%) were undergoing active treatment, male (94%), white (72%), and did not have a college degree (67%). The most commonly mentioned symptoms were lumps/swelling, pain, sore throat, difficulty swallowing, and voice changes. For all items, ≥75% reported each question was relevant to their R/M SCCHN experience and 94% reported the instrument captured their experiences with R/M SCCHN. CONCLUSION: Results provide support for the content validity of the FHNSI-10, inasmuch as all 10 items were spontaneously reported and considered relevant to R/M SCCHN. Content validity might be enhanced by adding cough and hearing impairment items; however, the existing FHNSI-10 covers the majority of symptoms uncovered in interviews with a small sample of R/M SCCHN patients.

Development of the Functional Assessment of Cancer Therapy-Carcinoid Syndrome Symptom Index.

OBJECTIVE: To develop a symptom-focused index to evaluate representative symptoms, treatment side effects, and emotional and functional well-being of patients with carcinoid syndrome (CS). METHODS: The development of the Functional Assessment of Cancer Therapy-Carcinoid Syndrome Symptom Index (FACT-CSI) followed US Food and Drug Administration guidelines for the development of patient-reported outcome (PRO) measures and involved the following: (a) literature review; (b) interviews with 14 CS patients; (c) interviews with 9 clinicians; and (d) instrument development involving input from a range of PRO measure development and CS experts. The resulting draft instrument underwent cognitive interviews with 7 CS patients. RESULTS: Forty-six CS sources were reviewed. Analysis of patient interviews produced 23 patient-reported symptoms. The most frequently endorsed physical symptoms were flushing, diarrhea, abdominal pain, fatigue, and food sensitivity/triggers. Seven priority CS emotional and functional themes were also identified by patients. Expert interviews revealed 12 unique priority symptoms - the most common being diarrhea, flushing, wheezing, edema, abdominal pain/cramping, fatigue, and 8 emotional and functional concerns. Through an iterative process of team and clinical collaborator meetings, data review, item reduction and measure revision, 24 items were selected for the draft symptom index representing symptoms, emotional concerns, global assessment of treatment side effects, and functional well-being. Cognitive interview results demonstrated strong content validity, including positive endorsement of item clarity (>86% across items), symptom relevance (>70% for most items), and overall measure content (86%). CONCLUSIONS: The FACT-CSI is a content-relevant, symptom-focused index reflecting the highest priority and clinically relevant symptoms and concerns of people with CS.

Validation of the Functional Assessment of Cancer Therapy-Leukemia instrument in patients with acute myeloid leukemia who are not candidates for intensive therapy.

BACKGROUND: The objective of this study was to validate the Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) in patients with acute myeloid leukemia (AML) who are not candidates for intensive therapy. METHODS: A sample of 317 patients with AML who were not eligible for intensive chemotherapy completed the FACT-Leu and EuroQol 5-Dimension (EQ-5D) measures (Utility Index and Visual Analogue Scale) every 28 days until the end of treatment. Internal consistency reliability was estimated with Cronbach's α. Concurrent validity was examined with correlations between FACT-Leu and EQ-5D scales, and known-groups validity was examined by determining whether FACT-Leu scales distinguished between Eastern Cooperative Oncology Group (ECOG) performance status ratings (PSRs) and between maximum adverse event toxicities at the baseline. This study examined responsiveness to change by anchoring change in the FACT-Leu scales to a 0.10 change in the EQ-5D Health Utility Index. RESULTS: Cronbach's α usually exceeded the threshold for good (≥0.80) or excellent reliability (≥0.90). Correlations between FACT-Leu and EQ-5D scales were moderate (r > 0.50) or high (r > 0.70). FACT-Leu scales distinguished between ECOG PSR groups with large effect sizes for an ECOG PSR of 0 versus an ECOG PSR of 2 (0.50 ≤ d < 0.80). In addition, Functional Assessment of Cancer Therapy-General, Additional Concerns, FACT-Leu Total, and Trial Outcomes Index scales distinguished between patients with grade 3 or lower maximum adverse event toxicities and those with maximum adverse event toxicities higher than grade 3, but effect sizes were small (d < 0.50). Finally, FACT-Leu scale coefficients for a 0.10 change in the 5-level version of the EQ-5D HUI ranged between -0.01 and 4.30. CONCLUSIONS: The FACT-Leu is a suitable outcome measure for AML clinical trials among patients not eligible for intensive therapy, and it may have value for clinical monitoring.

Financial burden and quality of life among thyroid cancer survivors.

BACKGROUND: Survivors of cancer in the United States are often financially encumbered by expenses and lost wages from cancer treatment. The majority of patients with thyroid cancer are diagnosed before age 65, when they are not eligible for Medicare. We hypothesized that financial distress would be common among thyroid cancer survivors and would be associated with poor health-related quality of life. METHODS: A financial distress questionnaire and Patient-Reported Outcomes Measurement Information System (29-item) were completed online by 1,743 adult thyroid cancer survivors living in the United States. Multivariable modeling was used to identify variables which independently predicted poor health-related quality of life. The magnitude of predicted change was estimated by ß coefficients and 95% confidence intervals. A ß ≥3 was considered clinically significant; α was set at 0.01. RESULTS: Financial difficulties were reported by 43% of thyroid cancer survivors and were associated with worse anxiety (ß = 5.07; P < .01) and depression (ß = 5.47; P < .01). Living in poverty was associated with worse anxiety (ß = 4.14; P < .01) and depression (ß = 4.35; P < .01). Lost productivity at work was associated with worse fatigue (ß = 5.99; P < .01) and social functioning (ß = -4.07; P < .01). Inability to change jobs was associated with worse fatigue (ß = 3.08; P < .01), pain interference (ß = 3.56; P < .01), and social functioning (ß = -3.09; P < .01). Receiving disability benefits was associated with worse pain interference (ß = 3.93; P < .01). Impaired ability to obtain a job was associated with worse social functioning (ß = -3.02; P < .01). Reported unemployment rate was 12.3%. CONCLUSION: Financial distress and negative financial events were common among thyroid cancer survivors and were associated with poorer health-related quality of life across 5 Patient-Reported Outcomes Measurement Information System health domains.

Assessment of Self-Management Treatment Needs Among COPD Helpline Callers.

Telephone quitlines are an effective population-based strategy for smoking cessation, particularly among individuals with tobacco-related diseases such as chronic obstructive pulmonary disease (COPD). Expanding quitline services to provide COPD-focused self-management interventions is potentially beneficial; however, data are needed to identify specific treatment needs in this population. We conducted a telephone-based survey (N = 5,772) to examine educational needs, behavioral health characteristics, and disease-related interference among individuals with COPD who received services from the American Lung Association (ALA) Lung Helpline. Most participants (73.7%) were interested in COPD-focused information, and few had received prior instruction in breathing exercises (33.9%), energy conservation (26.5%), or airway clearing (32.1%). About one-third of participants engaged in regular exercise, 16.3% followed a special diet, and 81.4% were current smokers. Most participants (78.2%) reported COPD-related interference in daily activities and 30.8% had been hospitalized within the past six months for their breathing. Nearly half of participants (45.4%) reported current symptoms of anxiety or depression. Those with vs. without anxiety/depression had higher rates of COPD-related interference (83.9% vs. 73.5%, p < .001) and past six-month hospitalization (33.4% vs. 28.3%, p < .001). In conclusion, this survey identified strong interest in disease-focused education; a lack of prior instruction in specific self-management strategies for COPD; and behavioral health needs in the areas of exercise, diet, and smoking cessation. Anxiety and depression symptoms were common and associated with greater disease burden, underscoring the importance of addressing coping with negative emotions. Implications for self-management treatments that target multiple behavioral needs of COPD patients are discussed.

Disease and treatment factors associated with lower quality of life scores in adults with multiple endocrine neoplasia type I.

BACKGROUND: Physical and psychosocial morbidity of multiple endocrine neoplasia type-1 is ill-defined. How disease and treatment-related factors relate to patient-reported outcomes including health-related quality of life is unknown. We hypothesized that disease and treatment burden negatively impacts health-related quality of life in adults with multiple endocrine neoplasia type-1. METHODS: Adults (≥18 years) with multiple endocrine neoplasia type-1 completed an online survey of demographics, disease features, treatments, and Patient-Reported Outcomes Measurement Information System 29-item profile measure, and scores were compared with normative US data. Multivariable modeling was performed to evaluate factors associated with decreased health-related quality of life. RESULTS: Multiple endocrine neoplasia type-1 patients (n = 207) reported worse health-related quality of life compared with US normative data in all health-related quality of life domains (P < .001). Persistent hypercalcemia after parathyroid surgery was associated with higher levels of anxiety, depression, fatigue, and decreased social functioning (P < .05). Patients <45 years of age at diagnosis reported worse physical and social functioning (P < .01). Traveling >50 miles for doctor appointments and ≥20 doctor appointments/year (P < .05) were associated with worse health-related quality of life. History of pancreatic neuroendocrine tumors was not associated with worse health-related quality of life. CONCLUSION: This is the largest study to assess clinical and treatment factors associated with health-related quality of life in multiple endocrine neoplasia type-1. Persistent hyperparathyroidism, increased travel distance and frequency of doctor appointments were all associated with worse health-related quality of life.

Financial burden is associated with worse health-related quality of life in adults with multiple endocrine neoplasia type 1.

BACKGROUND: Health-related quality of life and financial burden among patients with multiple endocrine neoplasia type 1 is poorly described. It is not known how financial burden influences health-related quality of life in this population. We hypothesized that the financial burden attributable to multiple endocrine neoplasia type 1 is associated with worse health-related quality of life. METHODS: United States adults (≥18 years) with multiple endocrine neoplasia type 1 were recruited from the AMENSupport MEN online support group. Patient demographics, clinical characteristics, and financial burden were assessed via an online survey. The instrument Patient-Reported Outcomes Measurement Information System 29-item profile measure was used to assess health-related quality of life. Multivariable linear regression was used to identify significant variables in each Patient-Reported Outcomes Measurement Information System domain. RESULTS: Out of 1,378 members in AMENSupport, our survey link was accessed 449 times (33%). Of 153 US respondents who completed our survey, 84% reported financial burden attributable to multiple endocrine neoplasia type 1. The degree of financial burden had a linear relationship with worse health-related quality of life across all Patient-Reported Outcomes Measurement Information System domains (r = 0.36-0.55, P < .001); 63% reported experiencing ≥1 negative financial event(s). Borrowing money from friends/family (30%), unemployment (13%), and spending >$100/month out-of-pocket on prescription medications (46%) were associated consistently with impaired health-related quality of life (ß = 3.75-6.77, P < .05). Respondents were 3- and 34-times more likely to be unemployed and declare bankruptcy than the US population, respectively. CONCLUSION: This study characterizes the financial burden in patients with multiple endocrine neoplasia type 1. Individuals with multiple endocrine neoplasia type 1 report a high degree of financial burden, negative financial events, and unemployment. Each of these factors was associated with worse health-related quality of life.

Health-Related Quality of Life in Patients with Idiopathic Pulmonary Fibrosis.

PURPOSE: Idiopathic pulmonary fibrosis (IPF) produces symptoms and activity limitations that impair health-related quality of life (HRQOL). The Patient-Reported Outcomes Measurement Information System(®) (PROMIS(®)) includes measures of self-reported health and HRQOL for a range of conditions. This study evaluated the HRQOL of individuals with IPF using PROMIS measures and examined associations between HRQOL and key symptoms or supplemental oxygen need. METHODS: Individuals who reported being told by a doctor that they have IPF completed an online battery of measures at baseline and 7-10 days later (for test-retest reliability). Measures included a brief survey of demographic and health-related questions, the PROMIS-29 profile, the Modified Medical Research Council Dyspnea Scale (MMRC), PROMIS dyspnea severity short form, A Tool to Assess Quality of life in IPF (ATAQ-IPF) and one cough item from the Functional Assessment of Chronic Illness Therapy (FACIT). RESULTS: 220 individuals were included in the final sample. Except for sleep disturbance, all PROMIS domain scores significantly (p < .01) differed by MMRC level. Supplemental oxygen users were more impaired than non-users in fatigue, physical function, and social role participation (p < 0.01). The test-retest reliability was acceptable to excellent (>0.7) for all scales, but was lower for sleep disturbance (0.64). CONCLUSIONS: People with IPF report substantial deficits in HRQOL across a range of PROMIS domains, and deficits vary by dyspnea and cough severity. These deficits warrant monitoring in clinical practice and consideration when investigating new therapies. Further research is required to further evaluate the psychometric performance of the PROMIS-29 in IPF.

Development and validation of the functional assessment of cancer therapy-antiangiogenesis subscale.

The Functional Assessment of Cancer Therapy (FACT)-Antiangiogenesis (AntiA) Subscale was developed and validated to enhance treatment decision-making and side effect management for patients receiving anti-angiogenesis therapies. Side effects related to anti-angiogenesis therapies were identified from the literature, clinician input, and patient input. Fifty-nine possible patient expressions of side effects were generated. Patient and clinician ratings of the importance of these expressions led us to develop a 24-item questionnaire with clinical and research potential. To assess the scale's reliability and validity, 167 patients completed the AntiA Subscale, the Functional Assessment of Cancer Therapy-general (FACT-G), the FACT-Kidney Symptom Index (FKSI), the FACIT-Fatigue Subscale, the Global Rating of Change Scale (GRC), and the PROMIS Global Health Scale. Patient responses to the AntiA were analyzed for internal consistency, test-retest reliability, convergent and discriminant validity, and responsiveness to change in clinical status. All tested scales were found to have good internal consistency reliability (Cronbach's alpha 0.70-0.92). Test-retest reliability was also good (0.72-0.88) for total and subscale scores and lower for individual items. The total score, subscale scores, and all single items (except nosebleeds) significantly differentiated between groups defined by level of side effect bother. Evaluation of responsiveness to change in this study was not conclusive, suggesting an area for further research. The AntiA is a reliable and valid measure of side effects from anti-angiogenesis therapy.

A qualitative study of unmet healthcare needs in chronic obstructive pulmonary disease. A potential role for specialist palliative care?

RATIONALE: Patients with chronic obstructive pulmonary disease (COPD) have high symptom burdens and poor health-related quality of life. The American Thoracic Society issued a consensus statement outlining the need for palliative care for patients with chronic respiratory diseases. A better understanding of the unmet healthcare needs among patients with COPD may help determine which aspects of palliative care are most beneficial. OBJECTIVES: To identify the unmet healthcare needs of patients with COPD hospitalized for exacerbation using qualitative methods. METHODS: We conducted 20 semistructured interviews of patients admitted for acute exacerbations of COPD focused on patient understanding of diagnosis and prognosis, effect of COPD on daily life and social relationships, symptoms, healthcare needs, and preparation for the end of life. Transcribed interviews were evaluated using thematic analysis. MEASUREMENTS AND MAIN RESULTS: Six themes were identified. (1) Understanding of disease: Most participants correctly identified their diagnosis and recognized their symptoms worsening over time. Only half understood their disease severity and prognosis. (2) SYMPTOMS: Breathlessness was universal and severe. (3) Physical limitations: COPD prevented participation in activities. (4) Emotional distress: Depressive symptoms and/or anxiety were present in most participants. (5) Social isolation: Most participants identified social limitations and felt confined to their homes. (6) Concerns about the future: Half of participants expressed fear about their future. CONCLUSIONS: There are many unmet healthcare needs among patients hospitalized for COPD exacerbation. Relief of symptoms, physical limitations, emotional distress, social isolation, and concerns about the future may be better managed by integrating specialist palliative care into our current care model.

A randomized trial of weekly symptom telemonitoring in advanced lung cancer.

CONTEXT: Lung cancer patients experience multiple, simultaneous symptoms related to their disease and treatment that impair functioning and health-related quality of life (HRQL). Computer technology can reduce barriers to nonsystematic, infrequent symptom assessment and potentially contribute to improved patient care. OBJECTIVES: To evaluate the efficacy of technology-based symptom monitoring and reporting in reducing symptom burden in patients with advanced lung cancer. METHODS: This was a prospective, multisite, randomized controlled trial. Two hundred fifty-three patients were enrolled at three sites and randomized to monitoring and reporting (MR) or monitoring alone (MA). Patients completed questionnaires at baseline, 3, 6, 9, and 12 weeks and symptom surveys via interactive voice response weekly for 12 weeks. MR patients' clinically significant symptom scores generated an e-mail alert to the site nurse for management. The primary endpoint was overall symptom burden; secondary endpoints included HRQL, treatment satisfaction, symptom management barriers, and self-efficacy. RESULTS: This randomized controlled trial failed to demonstrate efficacy of symptom monitoring and reporting in reducing symptom burden compared with monitoring alone in lung cancer. HRQL declined over 12 weeks in both groups (P < 0.006 to P < 0.025); at week 12, treatment satisfaction was higher in MA than MR patients (P < 0.012, P < 0.027). Adherence to weekly calls was good (82%) and patient satisfaction was high. CONCLUSION: Feasibility of using a technology-based system for systematic symptom monitoring in advanced lung cancer patients was demonstrated. Future research should focus on identifying patients most likely to benefit and other patient, provider, and health system factors likely to contribute to the system's success.

Measuring health-related quality of life in leukemia: the Functional Assessment of Cancer Therapy--Leukemia (FACT-Leu) questionnaire.

OBJECTIVE: Develop and validate a health-related quality-of-life (measure for patients with acute and chronic leukemia. METHODS: The study consisted of two phases: scale construction and scale validation. For the item-generation phase, a summary of the literature combined with qualitative results from item-generation interviews with 29 acute or chronic leukemia patients and 16 health care providers yielded an initial item pool reflecting leukemia-specific concerns and symptoms. Items underwent iterations of review and reduction according to defined retention criteria to support content validity, as defined by priority concerns of patients. Seventeen final leukemia-specific items were combined with the Functional Assessment of Cancer Therapy-General to create the FACT-Leukemia (FACT-Leu) scale. For the validation phase, 79 individuals with acute or chronic leukemia completed questionnaires at three time points. RESULTS: All FACT-Leu subscale and aggregated scores showed high internal consistency (αs ranging from 0.75 to 0.96). Test-retest reliability was adequate for all subscales (intraclass correlation range 0.765-0.890). The FACT-Leu scale demonstrated good convergent validity, with significant correlations with quality-of-life criteria and performance status, in the expected direction. FACT-Leu subscale scores were significantly different among the three performance status change groups, suggesting good responsiveness to change. CONCLUSIONS: The FACT-Leu scale is a valid, reliable, and efficient measure of leukemia-specific health-related quality of life for acute and chronic disease.

Oral health and oral health care practices among low-income pregnant women.

INTRODUCTION: Access to dental care is a problem in California as in many parts of the United States. Many women, including half of those having dental problems, do not see a dentist during pregnancy. The objective of this study was to describe the oral health status and oral health practices of low-income pregnant women in San Diego, California, and to determine the needs for oral health care education in this population. METHODS: This descriptive, retrospective, correlational study examined oral health and oral health care practices by age, ethnicity, and gravidity by using medical records from a convenience sample of 380 low-income pregnant women. RESULTS: Most participants were primigravida, aged between 19 and 29 years, of Hispanic ethnicity, and insured by the state (Medi-Cal). All women received education on oral health. The majority (84%) were encouraged to get a dental examination. It had been more than 1 year since the last dental visit for most women (55%). Hispanic women were in need of dental care more than Filipina women or women of other ethnicities. A broken tooth was the primary reason for immediate dental referrals. Regularity of flossing and brushing teeth differed significantly (P= .015, P < .001) across ethnic groups, with Filipina women reporting better oral care practices. DISCUSSION: The results provide information for the future planning of effective dental health promotion programs. Findings suggest that low-income pregnant women have some healthy oral health care practices but are in need of dental services and oral health education. An oral health history, oral health education, dental screening, and dental referral, if needed, should be a routine part of prenatal care and annual examinations.

Quality of life assessment in renal transplant: review and future directions.

We performed a systematic search of the literature using the MEDLINE (through 2006) database to identify the patient-reported outcome measures of quality of life (QOL) used most often in the renal transplant literature. After applying limits and reviewing references, we identified 338 renal transplant articles with a formal QOL assessment. Among the most frequently cited instruments were generic QOL tools, such as the Short Form-36, the Sickness Impact Profile, and the World Health Organization Quality of Life questionnaire. Other frequently cited instruments were more targeted in nature, such as the End-stage Renal Disease-Symptom Checklist and the Kidney Disease Quality of life questionnaire. In the present article, we review the most commonly used instruments, their use in renal transplant, and suggest future directions to improve QOL assessment in this population.

An innovative symptom monitoring tool for people with advanced lung cancer: a pilot demonstration.

Treatment for advanced lung cancer is not curative; therefore, the primary goals of its care are to maximize symptom management and minimize treatment toxicity. Increasingly, patient-reported symptoms and health-related quality of life (HRQL) outcomes have been accepted as important endpoints; several validated measures have gained wide acceptance in research, but their use in practice has been limited. Computer technology increasingly is used to reduce patient and administrative burden in conducting assessments to produce a real-time presentation of symptom and HRQL data. This paper describes a technology-based monitoring system developed for patients with advanced lung cancer who were starting chemotherapy. Among the 90 participants, compliance with the weekly symptom survey was 92%. Patient acceptability of the system was high, as evidenced by 30 patients who elected to complete an additional monitoring interval beyond the 12-week study period. Of patients who reported discussing their responses with a provider (95%), a majority (69%) stated that the questionnaire helped them to focus on issues to be discussed with their physicians. The system also was favorably reviewed by physicians, who indicated that the report helped them to compare patients' responses over time. Next steps will include a randomized trial to test the system's efficacy in improving symptom management.

Should health-related quality of life be measured in cancer symptom management clinical trials? Lessons learned using the functional assessment of cancer therapy.

There are several advantages to including comprehensive health-related quality of life (HRQL) in symptom trials in oncology. The most obvious is to test the hypothesis that HRQL will be improved in addition to the symptom benefit. We should not "require," however, that a successful symptom intervention also improve other dimensions of HRQL. On the other hand, we should expect that it will not make other dimensions worse through side effects or exacerbation of disease, even if it improves the symptom. HRQL assessment in the trial helps evaluate the competing risks of any therapy. Furthermore, assessment of HRQL is now accomplished with very brief assessment (usually 30 questions or less), and the knowledge gained is valuable. With HRQL, one can compare cancer patients with those with other conditions and can determine the contribution of symptoms and side effects to the more broadly defined HRQL. Examples using the Functional Assessment of Cancer Therapy measurement system will demonstrate how HRQL assessment has contributed to our understanding of common cancer symptoms and their place in the conceptualization of HRQL. The prevalence of clinically significant symptoms is greatest in poor performance status (PS) patients compared with patients with good PS. Symptom improvement trials specifically designed for these patients should be encouraged, particularly with interventions that can provide symptomatic relief and improve multidimensional HRQL.

Validation of the functional assessment of cancer therapy--lung symptom index-12 (FLSI-12).

We tested the reliability and validity of a brief symptom index for use with patients in the advanced stages of lung cancer. The Functional Assessment of Cancer Therapy--Lung Symptom Index-12 (FLSI-12) is a brief self-report measure that combines seven items addressing symptoms common in advanced-stage lung cancer with five symptoms or concerns that are relevant to most people with advanced-stage cancer. The index was administered prospectively to 92 advanced-stage lung cancer patients beginning at the initiation of chemotherapy and for 12 consecutive weeks. Reliability, convergent and concurrent validities, and responsiveness to change were determined and a minimally important difference (MID) was estimated. The index had good internal consistency (all Cronbach's alpha's>0.70), moderate to high item-to-total correlations (93% rho's> or =0.30), and correlated highly with a measure of overall quality of life (rho's> or =0.50). Baseline scores differentiated patients with better versus worse clinical features (p's<.05). Prospective changes in index scores were sensitive to changes in performance status ratings (p's<.05). An MID of 3-4 points was estimated by combining guideline-, distribution-, and anchor-based methods. The results show that the FLSI-12 is a psychometrically sound measure and support its use as an endpoint in clinical trials of advanced-stage lung cancer.

Development and validation of the Functional Assessment of Cancer Therapy-Kidney Symptom Index (FKSI).

The Functional Assessment of Cancer Therapy (FACT)-Kidney Symptom Index (FKSI) was developed and validated to enhance treatment decision-making, practice guidelines, symptom management, and treatment efficacy for kidney cancer patients. Thirty-four symptoms related to the disease were identified and tested. An equal weighting of patient and clinician ratings of the relative importance of each of these items led to production of a 15-item index (FKSI-15) and a 10-item abbreviated option (FKSI-10). To assess psychometric properties, patients completed the FKSI, Functional Assessment of Cancer Therapy-General (FACT-G), Eastern Cooperative Oncology Group-Performance Status Rating (ECOG-PSR), and a Global Rating of Change Scale (GRCS). Patient responses to the FKSI were analyzed for internal consistency, test-retest reliability, convergent and discriminant validity, and responsiveness to change in clinical status. The FKSI-10 showed high internal consistency; correlations between both FKSI-10 and the physical and functional well being domains of the FACT-G were high. The FKSI-10 differentiated patients grouped by ECOG-PSR (all P < 0.001) and discriminated patients based on their GRCS rating. The minimally important difference (MID) range estimate for the FKSI-10 was 2-4 points; the psychometric properties of the FKSI-15 were very similar (MID range, 3-5 points).Thus, the FKSI-15 and FKSI-10 are reliable and valid symptom indices for evaluating kidney cancer patients.

Validation of the Functional Assessment of Chronic Illness Therapy Fatigue Scale relative to other instrumentation in patients with rheumatoid arthritis.

OBJECTIVE: This study validated a brief measure of fatigue in rheumatoid arthritis (RA), the Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Scale. METHODS: The FACIT Fatigue was tested along with measures previously validated in RA: the Multidimensional Assessment of Fatigue (MAF) and Medical Outcomes Study Short-Form 36 (SF-36) Vitality. The sample included 636 patients with RA enrolled in a 24 week double blind, randomized clinical trial (RCT) of adalimumab versus placebo. RESULTS: The FACIT Fatigue showed good internal consistency (alpha = 0.86 to 0.87), strong association with SF-36 Vitality (r = 0.73 to 0.84) and MAF (r = -0.84 to -0.88), and the ability to differentiate patients according to clinical change using the American College of Rheumatology (ACR) response criteria (ACR 20/50/70). Psychometric performance of the FACIT Fatigue scale was comparable to that of the other 2 fatigue measures. A minimally important difference in FACIT Fatigue change score of 3-4 points was confirmed in a separate sample of 271 patients with RA enrolled in a second double blind RCT of adalimumab versus placebo. CONCLUSION: The FACIT Fatigue is a brief, valid measure for monitoring this important symptom and its effects on patients with RA.
