Purpose: To characterize pediatricians’ perceived constraints and areas of confidence in assessing patient-reported outcomes (PROs) in the U.S., and to test associations of these factors with implementing PRO assessment. Methods: Using a random sample from the members of American Medical Association, we recruited general pediatricians and pediatric subspecialists to complete a survey (July 2011 to December 2013). Perceived constraints and confidence in PRO assessment were compared by age, pediatric specialty (general pediatrics, 7 subspecialties), practice settings (academic, private), and region of practice. Multivariable logistic regression tested associations of demographic, constraint, and confidence factors with implementing PRO assessment. Findings: The survey was completed by 458 participants (response rate 48.5%); of them, 40.4%, 15.9%, 15.5%, and 8.1% were general pediatricians, cardiology, hematology/oncology, and pulmonary specialists, respectively. PRO assessment was implemented by 29.0% of the pediatricians. The top five constraints for PRO assessment included limited time/manpower (79.0%), limited training (77.4%), lengthy PRO instruments (76%), lack of meaningful cut-offs on PRO scores (75.5%), and unavailable PRO instruments (75.0%). Limited knowledge about PROs (OR 3.80; 95% CI 1.65, 4.80) and unavailability of PRO instruments (OR 1.81; 95% CI 1.04, 3.16) increased the odds of not implementing the assessment, whereas confidence in PRO assessments compatible with norms (OR 0.34; 95% CI 0.20, 0.58) and perceived benefit over clinical judgment alone (OR 0.58; 95% CI 0.34, 0.99) decreased the odds of not implementing the assessment. Interpretation: Significant barriers to PRO assessment in pediatric settings suggest the need for providing training, resources, and practical guidance toward implementation.

Background To the authors' knowledge, social network status in adolescent and young adult (AYA) cancer survivors has not been adequately studied to date. The authors developed and validated a functional social network index (FSNI) for AYA survivors, and compared its performance with that of 2 traditional indices (density and betweenness centrality). Methods A total of 102 AYA survivors and 102 noncancer controls who were matched for age, sex, and race were recruited from an Internet panel. Each participant reported relationships with up to 25 close friends and/or relatives. The authors developed a FSNI with reported marital status, contact frequency with friends/relatives, available resources for emotional and tangible support, and available resources for physical activity and weight management advice. Linear regression was used to analyze associations between the FSNI and cancer diagnoses, treatments, and coping skills. Results Based on the FSNI, survivors were found to have more available resources for emotional support (beta [b] = 3.02; P = .003), tangible support (b = 4.17; P .05) nor significant associations with coping skills (all P values >.05). Conclusions The FSNI appears to provide a better social network assessment for AYA cancer survivors than traditional indices. Cancer 2018;124:2220-7. © 2018 American Cancer Society.

Poor asthma control in children is related to impaired patient-reported outcomes (PROs; eg, fatigue, depressive symptoms, anxiety), but less well studied is the effect of PROs on children's school performance and sleep outcomes. In this study we investigated whether the consistency status of PROs over time affected school functioning and daytime sleepiness in children with asthma.Of the 238 children with asthma enrolled in the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Asthma Study, 169 children who provided survey data for all 4 time points were used in the analysis. The child's PROs, school functioning, and daytime sleepiness were measured 4 times within a 15-month period. PRO domains included asthma impact, pain interference, fatigue, depressive symptoms, anxiety, and mobility. Each child was classified as having poor/fair versus good PROs per meaningful cut points. The consistency status of each domain was classified as consistently poor/fair if poor/fair status was present for at least 3 time points; otherwise, the status was classified as consistently good. Seemingly unrelated regression was performed to test if consistently poor/fair PROs predicted impaired school functioning and daytime sleepiness at the fourth time point.Consistently poor/fair in all PRO domains was significantly associated with impaired school functioning and excessive daytime sleepiness (Ps .01) after controlling for the influence of the child's age, sex, and race/ethnicity.Children with asthma with consistently poor/fair PROs are at risk of poor school functioning and daytime sleepiness. Developing child-friendly PRO assessment systems to track PROs can inform potential problems in the school setting.

Survivors of lymphoma had the largest FSNI, whereas survivors of central nervous system malignancies had the smallest (b = 2.77; P = .02). A higher FSNI was associated with better coping skills: less denial (b = 0.10; P = .01), using emotional support (b = 0.08; P = .04), using instrumental support (b = 0.12; P.001), less behavioral disengagement (b = 0.08; P = .04), venting of emotions (b = 0.10; P = .004), positive reframing (b = 0.12; P = .003), planning for the future (b = 0.08; P = .03), and religious engagement (b = 0.16; P.001). Density and betweenness centrality indices demonstrated neither significant differences in social networks between cancer survivors and controls (all P values.05) nor significant associations with coping skills (all P values.05).The FSNI appears to provide a better social network assessment for AYA cancer survivors than traditional indices.

Background Health-related quality of life (HRQOL) is increasingly measured as an outcome for clinical and health services research. However, relatively little is known about how non-health factors affect HRQOL. Personality is a potentially important factor, yet evidence regarding the effects of personality on HRQOL measures is unclear. Methods This systematic review examined the relationships among aspects of personality and HRQOL. Eligible studies were identified from Medline and PsycINFO. The review included 76 English-language studies with HRQOL as a primary outcome and that assessed personality from the psychological perspective. Individuals with various health states, including ill (e.g., cancer, cardiovascular disorders), aging, and healthy, were included in this review study. Results Some personality characteristics were consistently related to psychosocial aspects more often than physical aspects of HRQOL. Personality characteristics, especially neuroticism, mastery, optimism, and sense of coherence were most likely to be associated with psychosocial HRQOL. Personality explained varying proportions of variance in different domains of HRQOL. The range of variance explained in psychosocial HRQOL was 0 to 45% and the range of explained variance in physical HRQOL was 0 to 39%. Conclusions Personality characteristics are related to HRQOL. Systematic collection and analysis of personality data alongside HRQOL measures may be helpful in medical research, clinical practice, and health policy evaluation.

e21563 Background: AYA cancer survivors are at risk of various adverse health outcomes, but the relation between health status, social integration (i.e., social network and support) and loneliness is understudied. Methods: 102 AYA survivors (mean age = 25 years; diagnoses = leukemia 27%; lymphoma 24%; brain tumors 9%; solid tumors 41%) and 102 age-sex-matched controls were recruited from a community-based online panel. Participants reported social network information (e.g., contact frequency, resources for health counseling) for up to 25 of closest friends/relatives, which was used to create a functional social network index. UCLA Loneliness Scale, Duke-UNC Functional Social Support Questionnaire and PROMIS Health Profile were used to measure loneliness, social support and health-related outcomes (physical functioning, depression, anxiety, fatigue and pain), respectively. Multiple linear regression was used to compare functional social network, social support and loneliness between survivors and controls, and to assess the relation between health outcomes and perceived loneliness. Results: Compared to controls, survivors of lymphoma (b = 1.98; p = 0.005), leukemia (b = 1.67; p = 0.012) and solid tumors (b = 1.22; p = 0.030) had a higher functional social network index. However, social support did not differ between survivors and controls (p’s > 0.05). Brain tumor survivors (b = 15.65; p = 0.006) and solid tumor survivors (b = 10.83; p < 0.001) had more loneliness than controls. Compared to low loneliness controls, high loneliness survivors had significantly lower physical functioning (b = -7.72; p < 0.001) and higher anxiety (b = 8.35; p < 0.001), depression (b = 10.57; p < 0.001), fatigue (b = 5.52; p = 0.011) and pain (b = 6.37; p < 0.001) after adjusting for age, sex, education, social integration, and number of self-reported chronic health conditions. Conclusions: Loneliness is significantly associated with poor health-related outcomes in AYA survivors, which is independent of the influence of social integration. Future research is warranted to understand the relation between health status and social interactions among AYA survivors to inform intervention-based strategies.
