60 Background: Several colorectal cancer (CRC) screening options are considered in guidelines for individuals at average-risk (IAR). These options differ in aspects such as invasiveness, recommended frequency, and precision that need to be compared and weighed. This study elicited and compared the relative importance that physicians and IAR place on these screening aspects. Methods: Primary care physicians [PCPs] and gastroenterologists [GIs] who recommended/performed ≥1 screening one month prior to study and adult IAR completed a discrete choice experiment (DCE). Participants repeatedly chose between screening tests described by type of test, frequency, true-positive (TP), true-negative (TN), and adenoma TP (physicians only). The instrument was tested in qualitative (physicians: n=6; IAR: n=6) and quantitative pilots (physicians: n=100; IAR: n=202). A mixed logit model was used to estimate relative attribute importance (RAI) and predicted choice probabilities for colonoscopy, multi-target stool DNA (mt-sDNA), fecal immunochemical test (FIT), and methylated septin 9 (mSEPT9) blood test. Generalizability to the population was confirmed. Results: 1,249 IAR and 400 physicians participated. IAR were 46% male and the mean age was 58.9. Physicians were 79% male and their mean age was 53.4. Preferences were most affected by TP rates (IAR RAI=58%; physicians RAI=42%). Physicians also placed high importance (RAI=41%) on adenoma TP rates. TN rates (IAR RAI=33%; physician RAI=9%), frequency (IAR RAI=6%; physician RAI=2%) and type (IAR RAI=4%; physician RAI=6%) were less important. Despite both IAR and physicians placing most importance on precision, preferences for screening modalities differed. On average, physicians preferred colonoscopy, while IAR preferred mt-sDNA over colonoscopy (p<0.001). Both preferred mt-sDNA and colonoscopy over FIT (p<0.001), with a mSEPT9 blood test being least preferred (p<0.001). Preferences of IAR were heterogeneous with individuals who underwent colonoscopy or sigmoidoscopy screening preferring colonoscopy and the rest preferring mt-sDNA (p<0.001). Conclusions: While both GI and PCPs overwhelmingly preferred colonoscopy, preferences of IAR were heterogenous, with mt-sDNA being preferred on average other modalities. Offering choices in addition to colonoscopy could improve screening uptake. [Table: see text]

Abstract Background The symptom burden associated with cancer and its treatment can negatively affect patients’ quality of life and survival. Symptom-focused collaborative care model (CCM) interventions can improve outcomes, but only if patients engage with them. We assessed the receptivity of severely symptomatic oncology patients to a remote nurse-led CCM intervention. Methods In a pragmatic, cluster-randomized, stepped-wedge trial conducted as part of the National Cancer Institute IMPACT Consortium (E2C2, NCT03892967), patients receiving cancer care were asked to rate their sleep disturbance, pain, anxiety, emotional distress, fatigue, and limitations in physical function. Patients reporting at least 1 severe symptom (≥7/10) were offered phone consultation with a nurse symptom care manager (RN SCM). Initially, patients had to “opt-in” to receive a call, but the protocol was later modified so they had to “opt-out” if they did not want a call. We assessed the impact of opt-in vs opt-out framing and patient characteristics on receptiveness to RN SCM calls. All statistical tests were 2-sided. Results Of the 1204 symptom assessments (from 864 patients) on which at least 1 severe symptom was documented, 469 (39.0%) indicated receptivity to an RN SCM phone call. The opt-out period (odds ratio [OR] = 1.61, 95% confidence interval [CI] = 1.12 to 2.32, P = .01), receiving care at a tertiary care center (OR = 3.59, 95% CI = 2.18 to 5.91, P &lt; .001), and having severe pain (OR = 1.80, 95% CI = 1.24 to 2.62, P = .002) were associated with statistically significantly greater willingness to receive a call. Conclusions Many severely symptomatic patients were not receptive to an RN SCM phone call. Better understanding of reasons for refusal and strategies for improving patient receptivity are needed.

AbstractObjectiveObesity is stigmatized and people with obesity report experiencing stigmatizing situations when seeking health care. The implications of these experiences are not well understood. This study tests an indirect effects model of negative care experiences as an intermediate variable between obesity and care avoidance/utilization and switching primary care doctors.MethodsA survey was completed by 2380 primary care patients in the Learning Health Systems Network (LHSNet) Clinical Data Research Network with a BMI >25 kg/m2. Measures included scales assessing stigmatizing situations, perceived patient‐centered communication, perceived respect, having delayed needed care, and having looked for a new primary doctor in the past 12 months. Sequential and serial indirect effects of care experiences and respect in the association between BMI and care utilization outcomes was modeled.ResultsThe hypothesized model was supported by findings. The associations between BMI and delaying needed care (OR = 1.06, p < 0.001) and attempting to switch primary doctors (OR = 1.02, p = 0.04) was mediated by both stigmatizing situations experienced in a health care context and lower patient‐centered communication. Lower perceived respect mediated the association between care experiences and utilization outcomes.ConclusionsPeople with higher BMIs may avoid care or switch doctors as a result of stigmatizing experiences and poor communication with doctors. These outcomes may contribute to morbidity in people with obesity if they delay or avoid care for health concerns when symptoms first present.

Introduction: Little is known about the characteristics and resources that enable patients with heart failure (HF) to engage in effective self-management. To address this gap in knowledge, we measured personal and health care resources for self-management and examined associations with mortality among patients with HF. Methods: We surveyed 5543 residents of 11 counties in Southeast Minnesota with a first-ever code for HF [International Classification of Disease, Ninth Revision code 428 or Tenth Revision code I50] between 1/1/2013 and 3/31/2016. Self-management resources were measured with the health care and personal subscales of the Chronic Illness Resources Survey (CIRS), both of which included 3 questions on a 5-point scale. The responses were averaged and participants were categorized as low if the mean score was below the median of the distribution (range from 1 to 5). The survey was returned by 2866 participants (response rate 52%) and those with complete data on the main items of interest were retained for analysis (N=2212). Cox proportional hazards regression was used to determine the association between each subscale and mortality. Results: Among 2212 participants (mean age 72.8 years, 54.1% men) the median health care score was 4, while the personal score was 3. Those with low health care resources were older and less educated than those with a higher score (p<0.05), while those with low personal resources had less comorbidities and lower education attainment compared to those with a higher score (p<0.05). After a mean (SD) follow-up of 1.3 ± 0.6 years, 207 deaths occurred. Low levels of both self-management resources were associated with an increased risk of death compared with patients with high levels (Table). Conclusions: Having limited self-management resources is associated with an increased risk of mortality among patients with HF. Thus, interventions aimed at supporting self-management among patients with HF may improve outcomes.

INTRODUCTION: Significant variability between colonoscopy operators contributes to postcolonoscopy colorectal cancers (CRCs). We aimed to estimate postcolonoscopy colorectal neoplasia (CRN) detection by multi-target stool DNA (mt-sDNA), which has not previously been studied for this purpose. METHODS: In a retrospective cohort of patients with +mt-sDNA and completed follow-up colonoscopy, positive predictive value (PPV) for endpoints of any CRN, advanced adenoma, right-sided neoplasia, sessile serrated polyps (SSP), and CRC were stratified by the time since previous colonoscopy (0–9, 10, and ≥11 years). mt-sDNA PPV at ≤9 years from previous average-risk screening colonoscopy was used to estimate CRN missed at previous screening colonoscopy. RESULTS: Among the 850 studied patients with +mt-sDNA after a previous negative screening colonoscopy, any CRN was found in 535 (PPV 63%). Among 107 average-risk patients having +mt-sDNA ≤9 years after last negative colonoscopy, any CRN was found in 67 (PPV 63%), advanced neoplasia in 16 (PPV 15%), right-sided CRN in 48 (PPV 46%), and SSP in 20 (PPV 19%). These rates were similar to those in 47 additional average risk persons with previous incomplete colonoscopy and in an additional 68 persons at increased CRC risk. One CRC (stage I) was found in an average risk patient who was mt-sDNA positive 6 years after negative screening colonoscopy. DISCUSSION: The high PPV of mt-sDNA 0–9 years after a negative screening colonoscopy suggests that lesions were likely missed on previous examination or may have arisen de novo . mt-sDNA as an interval test after negative screening colonoscopy warrants further study.

AbstractRecommended colorectal cancer screening modalities vary with respect to safety, efficacy, and cost. Better understanding of the factors that influence patient preference is, therefore, critical for improving population adherence to colorectal cancer screening. To address this knowledge gap, we conducted a panel survey focused on three commonly utilized colorectal cancer screening options [fecal immunochemical test or guaiac-based fecal occult blood test (FIT/gFOBT), multi-target stool DNA (mt-sDNA) test, and colonoscopy] with a national sample of U.S. adults, ages 40–75 years and at average risk of colorectal cancer, in November 2019. Of 5,097 panelists invited to participate, 1,595 completed the survey (completion rate, 31.3%). Our results showed that when presented a choice between two colorectal cancer screening modalities, more respondents preferred mt-sDNA (65.4%) over colonoscopy, FIT/gFOBT (61%) over colonoscopy, and mt-sDNA (66.9%) over FIT/gFOBT. Certain demographic characteristics and awareness of and/or experience with various screening modalities influenced preferences. For example, uninsured people were more likely to prefer stool-based tests over colonoscopy [OR, 2.53; 95% confidence interval (CI), 1.22–5.65 and OR, 2.73; 95% CI, 1.13–7.47]. People who had heard of stool-based screening were more likely to prefer mt-sDNA over FIT/gFOBT (OR, 2.07; 95% CI, 1.26–3.40). People who previously had a stool-based test were more likely to prefer FIT/gFOBT over colonoscopy (OR, 2.75; 95% CI, 1.74–4.41), while people who previously had a colonoscopy were less likely to prefer mt-sDNA or FIT/gFOBT over colonoscopy (OR, 0.39; 95% CI, 0.24–0.63 and OR, 0.40; 95% CI, 0.26–0.62). Our survey demonstrated broad patient preference for stool-based tests over colonoscopy, contrasting the heavy reliance on colonoscopy for colorectal cancer screening in clinical practice and highlighting the importance of considering patient preference in colorectal cancer screening recommendations.Prevention Relevance:Our national survey demonstrated broad patient preference for stool-based tests over colonoscopy, contrasting the heavy reliance on colonoscopy for colorectal cancer screening in clinical practice and highlighting the importance of considering patient preference in colorectal screening recommendations.

Background Prior reports indicate that living in a rural area may be associated with worse health outcomes. However, data on rurality and heart failure (HF) outcomes are scarce. Methods and Results Residents from 6 southeastern Minnesota counties with a first‐ever code for HF ( International Classification of Diseases, Ninth Revision [ ICD‐9 ], code 428, and International Classification of Diseases, Tenth Revision [ ICD‐10 ] code I50) between January 1, 2013 and December 31, 2016, were identified. Resident address was classified according to the rural‐urban commuting area codes. Rurality was defined as living in a nonmetropolitan area. Cox regression was used to analyze the association between living in a rural versus urban area and death; Andersen‐Gill models were used for hospitalization and emergency department visits. Among 6003 patients with HF (mean age 74 years, 48% women), 43% lived in a rural area. Rural patients were older and had a lower educational attainment and less comorbidity compared with patients living in urban areas ( P <0.001). After a mean (SD) follow‐up of 2.8 (1.7) years, 2440 deaths, 20 506 emergency department visits, and 11 311 hospitalizations occurred. After adjustment, rurality was independently associated with an increased risk of death (hazard ratio [HR], 1.18; 95% CI, 1.09–1.29) and a reduced risk of emergency department visits (HR, 0.89; 95% CI, 0.82–0.97) and hospitalizations (HR, 0.78; 95% CI, 0.73–0.84). Conclusions Among patients with HF, living in a rural area is associated with an increased risk of death and fewer emergency department visits and hospitalizations. Further study to identify and address the mechanisms through which rural residence influences mortality and healthcare utilization in HF is needed in order to reduce disparities in rural health.

27 Background: Colorectal cancer (CRC) is the second most deadly and fourth most frequently diagnosed cancer in the United States. Early detection can improve CRC outcomes, but overall screening rates (62%) remain below the 80% goal set by the National Colorectal Cancer Roundtable. Multiple options are endorsed for average-risk CRC screening, including the multi-target stool DNA (mt-sDNA) test, which includes patient and provider navigation support. Cross-sectional adherence with the mt-sDNA test was previously reported in a large Medicare population (71%). In the current study we investigated cross-sectional adherence with the mt-sDNA test in a broader, national sample of insured patients. Methods: Aggregate data from Exact Sciences Laboratories LLC (ESL; Madison, WI) were retrospectively analyzed in compliance with HIPAA requirements. Study participants included individuals ages 50 years and older who were covered by commercial insurance or Medicare, had a valid mt-sDNA test order placed between January 1–December 31, 2018, and received a test kit shipped from ESL. Cross-sectional adherence, defined as successful completion and return of the test kit within 365 days of the shipment date, was assessed overall and by patient- and provider-level factors. Results: In total, 1,420,460 participants met the study criteria (61.2% women; mean age 65.7 years). Overall cross-sectional adherence was 66.8%. Adherence was 72.1% in participants with Traditional Medicare, 69.1% in participants with Medicare Advantage, and 61.9% in participants with commercial insurance (p<0.001). Adherence increased by participant age (p<0.001): 60.8% for ages 50-64, 71.3% for ages 65-75, and 74.7% for ages 76+ years. For Traditional Medicare patients, ages 65-75, adherence was 73.6%. Participants with mt-sDNA tests ordered placed by gastroenterologists had a higher adherence rate (78.3%) than those with orders placed by primary care clinicians (67.2%) (p<0.001). Adherence rates were highest among patients with ordering providers in the Pacific region (71.4%) and West North Central region (70.1%), and lowest in the Mid-Atlantic region (65.7%), New England (65.2%), West South Central region (64.6%), and Puerto Rico and US territories (60.7%). Conclusions: Novel data from this large, national sample of insured patients demonstrate high cross-sectional adherence with the mt-sDNA test (66.8%), supporting the substantial contribution this guideline-endorsed option plays in average-risk CRC screening. At the patient-level, adherence increased with patient age, and was highest in those covered by Traditional Medicare. Provider-level stratification showed the highest adherence for mt-sDNA tests ordered by gastroenterologists. This study adds to data regarding the impact of accompanying navigation support and at-home convenience of mt-sDNA on screening completion rates.
