RESUMO
BACKGROUND: Patient participation in clinical trials is influenced by demographic and other individual level characteristics. However, there is less research on the role of geography and neighborhood-level factors on clinical trial participation. This study identifies the demographic, clinical, geographic, and neighborhood predictors of consenting to a clinical trial among cancer patients at a large, urban, NCI-designated cancer center in the Mid-Atlantic region. METHODS: We used demographic and clinical data from patients diagnosed with cancer between 2015 and 2017. We geocoded patient addresses and calculated driving distance to the cancer center. Additionally, we linked patient data to neighborhood-level educational attainment, social capital and cancer prevalence. Finally, we used generalized linear mixed-effects conditional logistic regression to identify individual and neighborhood-level predictors of consenting to a clinical trial. RESULTS: Patients with higher odds of consenting to trials were: Non-Hispanic White, aged 50-69, diagnosed with breast, GI, head/neck, hematologic, or certain solid tumor cancers, those with cancers at regional stage, never/former tobacco users, and those with the highest neighborhood social capital index. Patients who lived further from the cancer center had higher odds of consenting to a trial. With every 1-km increase in residential distance, there was a 4% increase in the odds that patients would consent to a trial. Neither of the additional neighborhood-level variables predicted consenting to a clinical trial. CONCLUSIONS: This study identifies important demographic, patient-level, and geographic factors associated with consenting to cancer clinical trials, and lays the groundwork for future research exploring the role of neighborhood-level factors in clinical trial participation.

Background: Although current evidence suggests that there are unique benefits of breastfeeding for mothers receiving comprehensive treatment, including counseling and pharmacotherapy, for opioid use disorder (OUD) and their infants, breastfeeding rates in this population are low. Support and counseling about breastfeeding are key predictors of infant feeding behaviors. Thus, identifying knowledge and attitudes regarding breastfeeding of individuals who work in OUD treatment facilities could offer insight into targets for breastfeeding-promotion interventions in such settings. Materials and Methods: Individuals who work at two urban perinatal OUD treatment centers were e-mailed a link to complete a questionnaire electronically. Breastfeeding knowledge, attitudes, and perceptions of those who completed the questionnaire were described using descriptive statistics. Results: Among the 24 survey respondents, most correctly identified the health benefits of breastfeeding for infants with neonatal abstinence syndrome, whereas less than half correctly identified the health benefits of breastfeeding for all infants. Only 16% reported receiving work-related breastfeeding education. The leading perceived breastfeeding challenges for women in treatment for OUD were (1) concern with transfer of medication (e.g., methadone) through breast milk, (2) daily commutes for treatment, and (3) beliefs that formula is better than breastfeeding. Conclusions: Professionals who work in perinatal OUD treatment centers could benefit from education regarding breastfeeding in mothers in treatment for OUD.
