Beyond methods to applied research: Realizing the vision of PROMIS®

Patients' perspectives about their health are critical to improving health outcomes. Patient reported outcomes (PRO) are emerging as a standard way to capture patient perspectives in clinical research and care delivery. Conventionally, researchers used lengthy fixed instruments that were burdensome and had limited applicability across disease groups and the life course. To address these challenges, the National Institutes of Health invested in the development of an innovative, paradigm-shifting measurement system: The Patient-Reported Outcomes Measurement Information System® (PROMIS®). This article provides an overview of the vision, funding, development, and growth of PROMIS® over the last 15 years. We highlight current and future research needs given the expanding adoption of PROMIS® across a variety of health care contexts. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Healthcare providers' discussions of physical activity with older survivors of cancer: Potential missed opportunities for health promotion

OBJECTIVES

Physical activity (PA) promotes physical functioning and health-related quality of life in older survivors of cancer. Using a population-based sample of Medicare Advantage beneficiaries, we aimed to characterize the survivors who reported discussing PA with their healthcare provider.

MATERIALS AND METHODS

Data from the Surveillance, Epidemiology, and End Results (SEER) cancer registries was linked with the 2008-2014 Medicare Health Outcomes Survey (MHOS). Older survivors diagnosed with localized- or regional-stage female breast, prostate, or colorectal cancer ≥24 months prior to survey and had visited a healthcare provider in the previous year were included in the multiple logistic regression model. Best-fitting models were identified using the Hosmer and Lemeshow Goodness-of-Fit test.

RESULTS

The final sample (N = 5630) included 3006 survivors who reported discussing PA and 2624 survivors who did not report discussing PA. Older survivors of cancer were significantly more likely to report discussing PA if they had a history of cardiovascular disease (p < .001), diabetes (p < .001), or musculoskeletal disease (p < .001); had a history of fall(s) in the previous twelve months (p = .003); or were obese (p < .001).

DISCUSSION

PA is an important aspect of the management of cancer, other comorbid conditions, and maintenance of physical functioning in older adulthood. The results suggest that PA discussions are not occurring consistently across survivors, and key opportunities for health promotion are being missed. Future work should identify ways to encourage these conversations in all cancer follow-up appointments.

Understanding care and outcomes in adolescents and young adult with Cancer: A review of the AYA HOPE study

Historically, adolescents and young adults (AYA) diagnosed with cancer have been an understudied population, and their unique care experiences, needs, and outcomes were not well understood. Thus, 10 years ago, the National Cancer Institute supported the fielding of the Adolescent and Young Adult Health Outcomes and Patient Experiences (AYA HOPE) study to address this gap. We recruited individuals diagnosed at ages 15 to 39 with germ cell, Hodgkin and non-Hodgkin lymphoma, acute lymphoblastic leukemia, and sarcoma from Surveillance, Epidemiology, and End Results cancer registries into the first multicenter population-based study of medical care, physical, and mental health outcomes for AYAs with cancer in the United States. This review of the 17 published manuscripts showed low awareness of clinical trials and substantial impact of cancer on financial burden, education and work, relationships and family planning, and physical and mental health. It highlights the feasibility of a longitudinal population-based study and key lessons learned for research on AYAs with cancer in and beyond the United States.

Examining the relative influence of multimorbidity on variations in older cancer patients’ experiences with care

14

Background: Cancer patients often have multiple chronic conditions and require complex care coordination. We compared older (ages 66+) cancer patients’ reports of their healthcare experiences based on level of multimorbidity. Methods: Data from the SEER-CAHPS combines cancer registry (Surveillance, Epidemiology, and End Results; SEER), patient experiences (Consumer Assessment of Healthcare Providers and Systems; CAHPS) and Medicare claims data. Multimorbidity was captured as: (1) the National Cancer Institute-Combined Comorbidity Index (NCCI, 16 Charlson conditions diagnosed ≤12 months prior to cancer); and (2) a Multimorbidity Burden Index (MBI), which categorizes conditions based on the impact to cancer treatment (no comorbidity, low/medium, and high). Outcomes were CAHPS patient experience measures: Doctor Communication, Getting Care Quickly, Getting Needed Care, Obtaining Prescription Drugs, Customer Service, and ratings of Overall Care, Personal Doctor, and Specialist. Multivariable linear regression provided associations of each multimorbidity measure with CAHPS measures controlling for standard case mix adjustors, years from diagnosis to survey and diagnostic stage. Results: The study cohort included 9305 cancer patients (53% male, 84% Non-Hispanic White, average age 77, average time from diagnosis 29 months), with a distribution of NCCI conditions as: 0 (cancer only), 73%; 1, 17%; ≥2, 10%. Cancer patients with NCCI = 0 and those with MBI = no comorbidity rated their Personal Doctor more negatively than those with any comorbidities ( p < 0.02). Those with NCCI ≥ 2 or MBI = low/medium reported better Doctor Communication ( p < 0.04). Those with high MBI rated their specialist physician better than those with no multimorbidity ( p = 0.04), and those with low/medium MBI reported better experiences Getting Care Quickly ( p = 0.02). No other associations were significant. Conclusions: Cancer patients with multimorbidity report better communication with their doctor and care = by = personal doctors and specialists. Increased attention to the care experiences of cancer patients with multimorbidity may lead to insights and interventions that benefit all cancer patients.

Moving forward toward standardizing analysis of quality of life data in randomized cancer clinical trials

Background

There is currently a lack of consensus on how health-related quality of life and other patient-reported outcome measures in cancer randomized clinical trials are analyzed and interpreted. This makes it difficult to compare results across randomized controlled trials (RCTs) synthesize scientific research, and use that evidence to inform product labeling, clinical guidelines, and health policy. The Setting International Standards in Analyzing Patient-Reported Outcomes and Quality of Life Endpoints Data for Cancer Clinical Trials (SISAQOL) Consortium aims to develop guidelines and recommendations to standardize analyses of patient-reported outcome data in cancer RCTs.

Methods and Results

Members from the SISAQOL Consortium met in January 2017 to discuss relevant issues. Data from systematic reviews of the current state of published research in patient-reported outcomes in cancer RCTs indicated a lack of clear reporting of research hypothesis and analytic strategies, and inconsistency in definitions of terms, including “missing data,”“health-related quality of life,” and “patient-reported outcome.” Based on the meeting proceedings, the Consortium will focus on three key priorities in the coming year: developing a taxonomy of research objectives, identifying appropriate statistical methods to analyze patient-reported outcome data, and determining best practices to evaluate and deal with missing data.

Conclusion

The quality of the Consortium guidelines and recommendations are informed and enhanced by the broad Consortium membership which includes regulators, patients, clinicians, and academics.

Measuring cancer care experiences: Introducing SEER-CAHPS

6595

Background: Care experience ratings are recognized as measures of healthcare quality. Here we introduce a new, public data resource, SEER-CAHPS, which links cancer registry data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) program with Medicare claims and the Medicare Consumer Assessment of Healthcare Providers and Systems (MCAHPS) survey. Methods: The SEER-CAHPS resource includes cancer registry data from 1973-2011 (diagnosis, incidence, mortality, and sociodemographic data), Medicare CAHPS survey data from 1998-2013 (sociodemographic, health status, and care experience ratings), and Medicare fee-for-service (FFS) claims data from 2002-2013. The survey includes global ratings of overall care, personal doctor, specialist, health plan, and prescription drug plans, and composite ratings of doctor communication, care coordination, getting needed care, and getting care quickly. Data also contain survey weights to account for the Medicare CAHPS sampling design. Cross-sectional and longitudinal analyses are possible. Results: Currently, SEER-CAHPS includes 205,339 individuals with a history of cancer documented in SEER (FFS: 26,802 with a survey before cancer diagnosis, and 55,231 with a survey after cancer diagnosis; Medicare Advantage [MA]: 57,227 with a survey before cancer diagnosis and 71,436 with a survey after cancer diagnosis). The data resource also includes 724,965 MCAHPS respondents without cancer in SEER regions (FFS: 282,592; MA: 447,358). The data provide insights on topics including experiences of cancer patients in their last year of life; experiences of cancer survivors; and the associations of guideline-concordant follow-up care with patient experiences among cancer survivors. We will demonstrate project sample-size estimation and present instructions for submitting data access applications. Conclusions: SEER-CAHPS, a new, publicly available resource, provides population-based, cancer-specific data on patient experiences, health outcomes and healthcare utilization.

United States Population-Based Estimates of Patient-Reported Outcomes Measurement Information System Symptom and Functional Status Reference Values for Individuals With Cancer

Purpose To estimate cancer population-based reference values in the United States for eight PROMIS (Patient-Reported Outcomes Measurement Information System) domains by age and stage of disease. Patients and Methods For the Measuring Your Health (MY-Health) study, persons newly diagnosed with cancer (prostate, colorectal, non-small-cell lung, non-Hodgkin lymphoma, breast, uterine, or cervical) from 2010 to 2012 (N = 5,284) were recruited through the National Cancer Institute's SEER Program. Participants were mailed surveys 6 to 13 months after diagnosis. Raking by race/ethnicity, age, and stage generated weighted average PROMIS scores for pain interference, fatigue, anxiety, depression, sleep disturbance, physical function, ability to participate in social roles, and cognitive function. PROMIS measures are standardized to a T-score metric, with a score of 50 representing the general US population mean. Clinically meaningful differences were defined as a 3-point difference in scores. Results Several reference values (means) for patients with cancer were worse than the general United States population norms of 50. These include pain interference (52.4), fatigue (52.2), and physical function (44.1). Reference values were highest (ie, showed greatest symptom burden) in lung cancer (pain interference, 55.5; fatigue, 57.3; depression, 51.4) and cervical cancer (anxiety, 53.2; sleep disturbance, 53.4). Reference values for patients age 65 to 84 years reported lower sleep disturbance, anxiety, and depression, and better cognitive function than younger patients. Cancer reference values were poorer among those with advanced disease compared with patients with limited or no evidence of disease, specifically physical function (41.1 v 46.6, respectively), fatigue (55.8 v 50.2, respectively), and pain interference (55.2 v 50.9, respectively). Conclusion In a large, population-based sample of patients with recently diagnosed cancer, we observed symptom severity and functional deficits by age, stage, and cancer type consistent with the expected impact of cancer diagnosis and treatment. These United States cancer reference values can help facilitate interpretation of the PROMIS domain scores in research studies or in clinical applications that measure and evaluate the symptom and functional burden patients with cancer experience after initial treatment.

Measuring experiences of patients with cancer with care: The SEER-CAHPS linked data resource

238

Background: Care experience ratings are recognized as measures of quality. We introduce a new resource, SEER-CAHPS, linking cancer registry data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) program with Medicare claims and the Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey. Methods: The SEER-CAHPS data resource includes registry data from 1973-2011 (diagnosis, incidence, mortality, and sociodemographic data), Medicare CAHPS survey data from 1998-2013 (sociodemographic, health status, and care experience ratings), and Medicare fee-for-service (FFS) claims data from 2002-2013. SEER-CAHPS includes global ratings of overall care, personal doctor, specialist, health plan, and prescription drug plan and composite ratings of doctor communication, care coordination, getting needed care, and getting care quickly. The data also contain optional survey weights to account for the Medicare CAHPS sampling design. Results: Currently, SEER-CAHPS includes 205,339 individuals with a history of cancer documented in SEER (FFS: 26,802 with a survey before cancer diagnosis, and 55,231 with a survey after cancer diagnosis; Medicare Advantage [MA]: 57,227 with a survey before cancer diagnosis and 71,436 with a survey after cancer diagnosis). The database also includes 724,965 MCAHPS respondents without cancer in SEER regions (FFS: 282,592; MA: 447,358). The data provide insights on topics including experiences of cancer patients in their last year of life; experiences of cancer survivors; experiences of dually eligible (Medicare-Medicaid) cancer patients; and the associations of guideline-concordant follow-up care with patient experiences among people with colorectal cancer. We will demonstrate project sample-size estimation and present instructions for submitting data access applications. Conclusions: SEER-CAHPS provides population-based, cancer-specific data on patient experiences and associations with both health outcomes and healthcare utilization.

Responsiveness of 8 Patient-Reported Outcomes Measurement Information System (PROMIS) measures in a large, community-based cancer study cohort

BACKGROUND

The Patient-Reported Outcomes Measurement Information System (PROMIS) was a National Institutes of Health-funded initiative to develop measures of symptoms and function. Responsiveness is the degree to which a measure can detect underlying changes over time. The objective of the current study was to document the responsiveness of 8 PROMIS measures in a large, population-based cancer cohort.

METHODS

The Measuring Your Health study recruited 2968 patients who were diagnosed with 1 of 7 cancers between 2010 and 2012 through 4 Surveillance, Epidemiology, and End Results registries. Participants completed a baseline survey (6-13 months after diagnosis) and a 6-month follow-up survey. Changes in 8 PROMIS scores were compared with global ratings of transition, changes in performance status, and clinical events.

RESULTS

Measures were responsive to 6-month declines and improvements in performance status with small to large effect sizes (ES) (Cohen d = 0.34-0.71; P < .01). Mean changes and effect sizes were larger for participants who reported declines compared with those who reported improvements. Small-to-medium ES were observed in patients who reported being "a little" worse (d = 0.31-0.56), and medium-to-large ES were observed in those who reported being "a lot" worse (d = 0.53-0.72). Hospitalized participants reported significant score increases, resulting in worsening of pain (d = 0.51), fatigue (d = 0.35), and depression (d = 0.57; all P < .01). Cancer recurrence and progression were associated with smaller increases in pain, fatigue, and sleep disturbance (d = 0.22-0.27).

CONCLUSIONS

The current results indicated that all 8 PROMIS measures were sensitive to patient-perceived worsening and improvement and to major clinical events. These findings will be able to inform the design and interpretation of future research studies and clinical initiatives administering PROMIS measures.

Use of complementary and alternative medicine and breast cancer survival in the Health, Eating, Activity, and Lifestyle Study

PURPOSE

Use of complementary and alternative medicine (CAM) is common among breast cancer patients, but less is known about whether CAM influences breast cancer survival.

METHODS

Health Eating, Activity, and Lifestyle (HEAL) Study participants (n = 707) were diagnosed with stage I-IIIA breast cancer. Participants completed a 30-month post-diagnosis interview including questions on CAM use (natural products such as dietary and botanical supplements, alternative health practices, and alternative medical systems), weight, physical activity, and comorbidities. Outcomes were breast cancer-specific and total mortality, which were ascertained from the Surveillance Epidemiology and End Results registries in Western Washington, Los Angeles County, and New Mexico. Cox proportional hazards regression models were fit to data to estimate hazard ratios (HR) and 95 % confidence intervals (CI) for mortality. Models were adjusted for potential confounding by sociodemographic, health, and cancer-related factors.

RESULTS

Among 707 participants, 70 breast cancer-specific deaths and 149 total deaths were reported. 60.2 % of participants reported CAM use post-diagnosis. The most common CAM were natural products (51 %) including plant-based estrogenic supplements (42 %). Manipulative and body-based practices and alternative medical systems were used by 27 and 13 % of participants, respectively. No associations were observed between CAM use and breast cancer-specific (HR 1.04, 95 % CI 0.61-1.76) or total mortality (HR 0.91, 95 % CI 0.63-1.29).

CONCLUSION

Complementary and alternative medicine use was not associated with breast cancer-specific mortality or total mortality. Randomized controlled trials may be needed to definitively test whether there is harm or benefit from the types of CAM assessed in HEAL in relation to mortality outcomes in breast cancer survivors.

Who Treats Adolescents and Young Adults with Cancer? A Report from the AYA HOPE Study

PURPOSE

Physicians play a critical role in delivering effective treatment and enabling successful transition to survivorship among adolescent and young adult (AYA) cancer patients. However, with no AYA cancer medical specialty, information on where and by whom AYAs with cancer are treated is limited.

METHODS

Using the National Cancer Institute's population-based AYA HOPE Study, 464 AYAs aged 15-39 at diagnosis treated by 903 physicians were identified. Differences in physician and hospital characteristics were examined by age at diagnosis and cancer type (germ cell cancer, non-Hodgkin lymphoma, Hodgkin lymphoma, acute lymphocytic leukemia [ALL], and sarcoma) using chi-square tests.

RESULTS

Treating physicians were predominately 51-64 years old, male, United States-trained in non-pediatric specialties, and in group practices within large metropolitan areas. Older patients were less often treated by pediatric physicians (p < 0.01) and more likely to be treated by United States-trained physicians without research/teaching responsibilities and in hospitals without residency programs (p < 0.05). The majority of the few pediatricians (n = 44) treated ALL patients. Physicians with research/teaching responsibilities and those based in medical schools were more likely to treat patients with ALL and sarcoma compared with other cancer types (p < 0.01). Of HL patients, 73% were treated at a cancer center compared with 56% of patients with germ cell cancer (p < 0.01), while ALL (85%) and sarcoma (87%) patients were more likely to be treated in hospitals with residency programs (p < 0.01).

CONCLUSIONS

Most AYAs with cancer were treated by non-pediatric physicians in community settings, although physician characteristics varied significantly by patient cancer type and age at diagnosis.

The challenge of measuring intra-individual change in fatigue during cancer treatment

PURPOSE

To evaluate how well three different patient-reported outcomes (PROs) measure individual change.

METHODS

Two hundred and fourteen patients (from two sites) initiating first or new chemotherapy for any stage of breast or gastrointestinal cancer participated. The 13-item FACIT Fatigue scale, a 7-item PROMIS^® Fatigue Short Form (PROMIS 7a), and the PROMIS^® Fatigue computer adaptive test (CAT) were administered monthly online for 6 months. Reliability of measured change was defined, under a population mixed effects model, as the ratio of estimated systematic variance in rate of change to the estimated total variance of measured individual differences in rate of change. Precision of individual measured change, the standard error of measurement of change, was given by the square root of the rate-of-change sampling variance. Linear and quadratic models were examined up to 3 and up to 6 months.

RESULTS

A linear model for measured change showed the following by 6 and 3 months, respectively: PROMIS CAT (0.363 and 0.342); PROMIS SF (0.408 and 0.533); FACIT (0.459 and 0.473). Quadratic models offered no noteworthy improvement over linear models. Both reliability and precision results demonstrate the need to improve the measurement of intra-individual change.

CONCLUSIONS

These results illustrate the challenge of reliably measuring individual change in fatigue with a level of confidence required for intervention. Optimizing clinically useful measurement of intra-individual differences over time continues to pose a challenge for PROs.

Cancer negatively impacts on sexual function in adolescents and young adults: The AYA HOPE study

OBJECTIVE

This cohort study examined the impact of cancer on sexual function and intimate relationships in adolescents and young adults (AYAs). We also explored factors predicting an increased likelihood that cancer had negatively affected these outcomes.

METHODS

Participants (n = 465, ages 15-39) in the Adolescent and Young Adult Health Outcomes and Patient Experience (AYA HOPE) study completed two surveys approximately 1 and 2 years post-cancer diagnosis. We used multivariable logistic regression to determine factors negatively affected by perceptions of sexual function at 2 years post-diagnosis.

RESULTS

Forty-nine percent of AYAs reported negative effects on sexual function at 1 year post-cancer diagnosis and 70% of those persisted in their negative perceptions 2 years after diagnosis. Those reporting a negative impact at 2 years were more likely to be 25 years or older (OR, 2.53; 95% CI, 1.44-4.42), currently not raising children (OR, 1.81; 95% CI, 1.06-3.08), experiencing fatigue (OR, 0.99; 95% CI, 0.975-0.998) and more likely to report that their diagnosis has had a negative effect on physical appearance (OR, 3.08; 95% CI, 1.97-4.81). Clinical factors and mental health were not significant predictors of negative effects on sexual function.

CONCLUSIONS

Many AYAs diagnosed with cancer experience a persistent negative impact on sexual life up to 2 years following diagnosis. The findings underscore the need to develop routine protocols to assess sexual function in AYAs with cancer and to provide comprehensive management in the clinical setting.

Cancer registry-survey data linkages to measure patient-centered quality of care: SEER-MHOS and SEER-CAHPS

303

Background: Limited opportunities exist to conduct population-based surveillance of cancer patient-reported outcomes. Data from the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) program has recently been linked with data from two Centers for Medicare & Medicaid Services quality improvement surveys: the Medicare Health Outcomes Survey (MHOS) and the Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys. We provide an overview of the data available, recent findings, and priority areas for future research. Methods: Since 1998, the MHOS has conducted 2-wave/biennial surveys of individuals ages 65+ and individuals with disabilities enrolled in Medicare Advantage (MA) health plans on aspects of health-related quality of life, functional status, comorbidities, and symptoms. Fourteen cohorts are available, representing over 126K patients with cancer and over 1.9 million MA enrollees without a history of cancer. The SEER-MHOS publicly available data resource has produced over 40 data use agreements and 19 publications. SEER-CAHPS links cancer registry data with cross-sectional survey data of Medicare beneficiaries (both fee-for-service and MA) that contain information on patient experiences with care, including access to needed and timely care, doctor communication, health plan customer service, and care coordination. The current linkage contains survey data from 1998 to 2010 and includes over 150K and 570K respondents with and without a history of cancer, respectively. Plans to launch the publicly available resource are underway. Results: Recent findings include the impact of diagnosis and treatment on health-related quality of life in older cancer survivors, physical health impairments and variation of treatment received, the impact of cancer on activities of daily living, and variations in care ratings between participants with and without cancer across the cancer control continuum. Conclusions: The SEER-MHOS and SEER-CAHPS linked data resources provide population-based surveillance data on cancer patient-reported outcomes which allow unprecedented opportunities to evaluate national quality improvement activities.

Next steps for adolescent and young adult oncology workshop: An update on progress and recommendations for the future

Each year, 70,000 adolescents and young adults (AYAs) between ages 15 and 39 years in the United States are diagnosed with cancer. In 2006, a National Cancer Institute (NCI) Progress Review Group (PRG) examined the state of science associated with cancer among AYAs. To assess the impact of the PRG and examine the current state of AYA oncology research, the NCI, with support from the LIVESTRONG Foundation, sponsored a workshop entitled "Next Steps in Adolescent and Young Adult Oncology" on September 16 and 17, 2013, in Bethesda, Maryland. This report summarizes the findings from the workshop, opportunities to leverage existing data, and suggestions for future research priorities. Multidisciplinary teams that include basic scientists, epidemiologists, trialists, biostatisticians, clinicians, behavioral scientists, and health services researchers will be essential for future advances for AYAs with cancer.

Patterns of Chronic Conditions and Their Associations With Behaviors and Quality of Life, 2010

INTRODUCTION

Co-occurring chronic health conditions elevate the risk of poor health outcomes such as death and disability, are associated with poor quality of life, and magnify the complexities of self-management, care coordination, and treatment planning. This study assessed patterns of both singular and multiple chronic conditions, behavioral risk factors, and quality of life in a population-based sample.

METHODS

In a national survey, adults (n = 4,184) answered questions about the presence of 27 chronic conditions. We used latent class analysis to identify patterns of chronic conditions and to explore associations of latent class membership with sociodemographic characteristics, behavioral risk factors, and health.

RESULTS

Latent class analyses indicated 4 morbidity profiles: a healthy class (class 1), a class with predominantly physical health conditions (class 2), a class with predominantly mental health conditions (class 3), and a class with both physical and mental health conditions (class 4). Class 4 respondents reported significantly worse physical health and well-being and more days of activity limitation than those in the other latent classes. Class 4 respondents were also more likely to be obese and sedentary, and those with predominantly mental health conditions were most likely to be current smokers.

CONCLUSIONS

Subgroups with distinct patterns of chronic conditions can provide direction for screening and surveillance, guideline development, and the delivery of complex care services.

Adolescent and young adult cancer survival

Adolescent and young adults (AYAs) face challenges in having their cancers recognized, diagnosed, treated, and monitored. Monitoring AYA cancer survival is of interest because of the lack of improvement in outcome previously documented for these patients as compared with younger and older patient outcomes. AYA patients 15-39 years old, diagnosed during 2000-2008 with malignant cancers were selected from the SEER 17 registries data. Selected cancers were analyzed for incidence and five-year relative survival by histology, stage, and receptor subtypes. Hazard ratios were estimated for cancer death risk among younger and older ages relative to the AYA group. AYA survival was worse for female breast cancer (regardless of estrogen receptor status), acute lymphoid leukemia (ALL), and acute myeloid leukemia (AML). AYA survival for AML was lowest for a subtype associated with a mutation of the nucleophosmin 1 gene (NPM1). AYA survival for breast cancer and leukemia remain poor as compared with younger and older survivors. Research is needed to address disparities and improve survival in this age group.

Estimating the health and economic burden of cancer among those diagnosed as adolescents and young adults

Adolescent and young adult cancer survivors-those who were ages 15-39 at their first cancer diagnosis-have important health limitations. These survivors are at risk for higher health care expenditures and lost productivity, compared to adults without a history of cancer. Using Medical Expenditure Panel Survey data, we present nationally representative estimates of the economic burden among people who were diagnosed with cancer in adolescence or young adulthood. Our findings demonstrate that surviving cancer at this age is associated with a substantial economic burden. Compared to adults without a history of cancer, adolescent and young adult cancer survivors had excess annual medical expenditures of $3,170 per person and excess annual productivity losses of $2,250 per person. Multifaceted prevention strategies, including education and sustained intervention programs to ensure access to lifelong risk-based follow-up care, may be effective ways to improve the economic outcomes associated with cancer survivorship in this population.

Development and Initial Validation of the PROMIS(®) Sexual Function and Satisfaction Measures Version 2.0

INTRODUCTION

The Patient-Reported Outcomes Measurement Information System (PROMIS)(®) Sexual Function and Satisfaction measure (SexFS) version 1.0 was developed with cancer populations. There is a need to expand the SexFS and provide evidence of its validity in diverse populations.

AIM

The aim of this study was to describe the development of the SexFS v2.0 and present preliminary evidence for its validity.

METHODS

Development built on version 1.0, plus additional review of extant items, discussions with 15 clinical experts, 11 patient focus groups (including individuals with diabetes, heart disease, anxiety, depression, and/or are lesbian, gay, bisexual, or aged 65 or older), 48 cognitive interviews, and psychometric evaluation in a random sample of U.S. adults plus an oversample for specific sexual problems (2281 men, 1686 women). We examined differential item functioning (DIF) by gender and sexual activity. We examined convergent and known-groups validity.

RESULTS

The final set of domains includes 11 scored scales (interest in sexual activity, lubrication, vaginal discomfort, clitoral discomfort, labial discomfort, erectile function, orgasm ability, orgasm pleasure, oral dryness, oral discomfort, satisfaction), and six nonscored item pools (screeners, sexual activities, anal discomfort, therapeutic aids, factors interfering with sexual satisfaction, bother). Domains from version 1.0 were reevaluated and improved. Domains considered applicable across gender and sexual activity status, namely interest, orgasm, and satisfaction, were found to have significant DIF. We identified subsets of items in each domain that provided consistent measurement across these important respondent groups. Convergent and known-groups validity was supported.

CONCLUSIONS

The SexFS version 2.0 has several improvements and enhancements over version 1.0 and other extant measures, including expanded evidence for validity, scores centered around norms for sexually active U.S. adults, new domains, and a final set of items applicable for both men and women and those sexually active with a partner and without. The SexFS is customizable, allowing users to select relevant domains and items for their study.

Cancer-related information needs and cancer's impact on control over life influence health-related quality of life among adolescents and young adults with cancer

OBJECTIVE

Adolescents and young adults (AYAs) diagnosed with cancer between 15 and 39 years of age often report need for greater amounts of cancer-related information and perceive that cancer has had a negative impact on control over their life. We examined whether unmet information need and perceived control over life are associated with health-related quality of life (HRQOL).

METHODS

We examined data from 484 AYA cancer survivors recruited from population-based cancer registries in 2007-2008. Participants completed surveys a median of 11 months after diagnosis. Multivariable linear regression analyses estimated associations of unmet cancer-related information needs and impact of cancer on control over life on HRQOL (SF-12).

RESULTS

Two-thirds of AYAs reported an intermediate or high level of unmet information need, and half (47%) reported a negative impact of cancer on control. Greater unmet information need was associated with lower overall mental and physical HRQOL and lower levels of all HRQOL subscales except vitality. A negative impact on control over life was associated with lower overall mental HRQOL as well as lower HRQOL across all subscales except general health perceptions (all p <0.05). In multivariable analyses, perceived control and unmet information need were independently associated with HRQOL (p-values for interaction >0.1).

CONCLUSIONS

Adolescent and young adult patients with cancer have high levels of unmet cancer-related information needs and perceived negative impact of cancer on control over life; both were independently associated with lower HRQOL. Addressing unmet information needs among AYA cancer survivors and finding ways to increase their sense of control may help improve HRQOL in this understudied population.

Fertility preservation knowledge, counseling, and actions among adolescent and young adult patients with cancer: A population-based study

BACKGROUND

The fertility of adolescent and young adult (AYA) patients with cancer can be threatened by treatments, but to the authors' knowledge little is known regarding the extent to which providers discuss this with patients or recommend fertility preservation, or the patient and physician characteristics associated with these interactions.

METHODS

Questionnaires from 459 AYA patients with cancer who were diagnosed between 2007 and 2008 and recruited through 7 US population-based cancer registries were analyzed using sex-specific multivariable models. The authors assessed characteristics associated with not discussing therapy effects on fertility or fertility preservation options, and not making fertility preservation arrangements.

RESULTS

Males without a medical oncologist were more likely not to be told that therapy might affect fertility than those with a medical oncologist (male odds ratio [OR], 2.28; 95% confidence interval [95% CI], 1.03-5.00). Individuals without insurance (male OR, 2.91 [95% CI, 1.41-5.91] and female OR, 5.46 [95% CI, 1.59-18.72]); those raising children aged <18 years; and, among males only, those who received treatment posing no or a low fertility risk (OR, 3.39; 95% CI, 1.60-7.16) were more likely not to discuss fertility preservation with providers. Finally, among males, those without a college degree (OR, 1.98; 95% CI, 1.00-3.97), lacking private insurance (OR, 2.97; 95% CI, 1.16-7.63), and raising children aged <18 years (OR, 3.53; 95% CI, 1.63-7.65) were more likely to not make fertility preservation arrangements; too few females had made fertility preservation arrangements for similar analyses to be performed.

CONCLUSIONS

Discussion and action surrounding fertility preservation for AYA patients with cancer are associated with medical factors, patient socioeconomic data, and child-rearing status. These results highlight the need for insurance coverage for fertility preservation and increased awareness of fertility preservation options.

High-gain cryogenic amplifier assembly employing a commercial CMOS operational amplifier

We have developed a cryogenic amplifier for the measurement of small current signals (10 fA-100 nA) from cryogenic optical detectors. Typically operated with gain near 10(7) V/A, the amplifier performs well from DC to greater than 30 kHz and exhibits noise level near the Johnson limit. Care has been taken in the design and materials to control heat flow and temperatures throughout the entire detector-amplifier assembly. A simple one-board version of the amplifier assembly dissipates 8 mW to our detector cryostat cold stage, and a two-board version can dissipate as little as 17 μW to the detector cold stage. With current noise baseline of about 10 fA/(Hz)(1/2), the cryogenic amplifier is generally useful for cooled infrared detectors, and using blocked impurity band detectors operated at 10 K, the amplifier enables noise power levels of 2.5 fW/(Hz)(1/2) for detection of optical wavelengths near 10 μm.
