Project description:ImportanceIncreasing participation in fecal screening tests is a major challenge in countries that have implemented colorectal cancer (CRC) screening programs.ObjectiveTo determine whether providing general practitioners (GPs) a list of patients who are nonadherent to CRC screening enhances patient participation in fecal immunochemical testing (FIT).Design, setting, and participantsA 3-group, cluster-randomized study was conducted from July 14, 2015, to July 14, 2016, on the west coast of France, with GPs in 801 practices participating and involving adult patients (50-74 years) who were at average risk of CRC and not up-to-date with CRC screening. The final follow-up date was July 14, 2016.InterventionsGeneral practitioners were randomly assigned to 1 of 3 groups: 496 received a list of patients who had not undergone CRC screening (patient-specific reminders group, 10 476 patients), 495 received a letter describing region-specific CRC screening adherence rates (generic reminders group, 10 606 patients), and 455 did not receive any reminders (usual care group, 10 147 patients).Main outcomes and measuresThe primary end point was patient participation in CRC screening 1 year after the intervention.ResultsAmong 1482 randomized GPs (mean age, 53.4 years; 576 women [38.9%]), 1446 participated; of the 33 044 patients of these GPs (mean age, 59.7 years; 17 949 women [54.3%]), follow-up at 1 year was available for 31 229 (94.5%). At 1 year, 24.8% (95% CI, 23.4%-26.2%) of patients in the specific reminders group, 21.7% (95% CI, 20.5%-22.8%) in the generic reminders group, and 20.6% (95% CI, 19.3%-21.8%) in the usual care group participated in the FIT screening. The between-group differences were 3.1% (95% CI, 1.3%-5.0%) for the patient-specific reminders group vs the generic reminders group, 4.2% (95% CI, 2.3%-6.2%) for the patient-specific reminders group vs the usual care group, and 1.1% (95% CI, -0.6% to 2.8%) for generic reminders group vs the usual care group.Conclusions and relevanceProviding French GPs caring for adults at average risk of CRC with a list of their patients who were not up-to-date with their CRC screening resulted in a small but significant increase in patient participation in FIT screening at 1 year compared with patients who received usual care. Providing GPs with generic reminders about regional rates of CRC screening did not increase screening rates compared with usual care.Trial registrationclinicaltrials.gov Identifier: NCT02515344.

Project description:Despite the documented benefits of colorectal cancer screening, patient participation rates remain low. Physician recommendation has been identified as a significant predictor of screening completion.The aim of this study is to investigate how primary care physicians perceive colorectal cancer screening communication tasks, as well as to explore the form and content of actual screening discussions.The research design includes a mailed physician survey and a separate observational study in a sample of videotaped medical encounters. PARTICIPANTS AND DATA SOURCES: The participants were 270 primary care physicians who completed a mailed questionnaire (57.9% response rate) and 18 physician-patient encounters that included discussions of colorectal cancer screening.The questionnaire focused on perceived importance and accomplishment of communication tasks relevant to colorectal cancer screening. Two of the authors reviewed transcripts of videotaped physician encounters to determine whether the same communication tasks assessed in the survey were accomplished. Interrater reliability was high across all of the mutually exclusive coding categories (Kappa > .90).Physicians rated colonoscopy as the most important screening option to discuss; self-reports indicate that colonoscopy (84.8%) is more frequently mentioned than fecal occult blood test (FOBT; 49.4%), flexible sigmoidoscopy (34.1%), or computed tomography (CT) imaging (18.1%). Explaining benefits and risks, describing test procedure and frequency, eliciting patient preferences, and making a plan for screening were all viewed as very important. Self-reported accomplishment of these communication tasks was considerably higher than that observed in our separate videotape sample.Most physicians recognize and espouse the importance of recommending colorectal cancer screening to eligible patients. However, findings from both the physician survey and observational study suggest that physicians tend to overestimate the extent of discussions about screening. Interventions may be warranted to improve clinical practice.

Project description:BackgroundLatinos have lower rates of colorectal cancer (CRC) screening and later stage diagnosis than Whites, which may be partially explained by physician communication factors.ObjectiveWe assessed associations between patient-reported physician counseling regarding CRC screening and receipt of CRC screening among Latino primary care patients.DesignThis was a cross-sectional telephone survey.ParticipantsThe participants of this study were Latino primary care patients 50 years of age or older, with one or more visits during the preceding year.Main measuresWe developed patient-reported measures to assess whether physicians provided explanations of CRC risks and tests, elicited patients' barriers to CRC screening, were responsive to patients' concerns about screening, and encouraged patients to be screened. Outcomes were patient reports of receipt of endoscopy (sigmoidoscopy or colonoscopy) and fecal occult blood test (FOBT) within recommended guidelines.Key resultsOf 817 eligible patients contacted, 505 (62 %) completed the survey; mean age was 61 years (SD 8.4), 69 % were women, and 53 % had less than high school education. Forty-six percent reported obtaining endoscopy (with or without FOBT), 13 % reported FOBT only, and 41 % reported no CRC screening. In bivariate analyses, physician explanations, elicitation of barriers, responsiveness to concerns, and greater encouragement for screening were associated with receipt of endoscopy (p < 0.001), and explanations (p < 0.05) and encouragement (p < 0.001) were associated with FOBT. Adjusting for covariates, physician explanations (OR = 1.27; 95 % CI 1.03, 1.58) and greater physician encouragement (OR = 6.74; 95 % CI 3.57, 12.72) were associated with endoscopy; patients reporting quite a bit/a lot of physician encouragement had six times higher odds of obtaining the FOBT as those reporting none/a little encouragement (OR = 6.54; 95 % CI 2.76, 15.48).ConclusionsAmong primarily lower-socioeconomic status Latino patients, the degree to which patients perceived that physicians encouraged CRC screening was more strongly associated with screening than with providing risk information, eliciting barriers, and responding to their concerns about screening.

Project description:ImportanceAlthough colonoscopy is frequently performed in the United States, there is limited evidence to support threshold values for physician adenoma detection rate as a quality metric.ObjectiveTo evaluate the association between physician adenoma detection rate values and risks of postcolonoscopy colorectal cancer and related deaths.Design, setting, and participantsRetrospective cohort study in 3 large integrated health care systems (Kaiser Permanente Northern California, Kaiser Permanente Southern California, and Kaiser Permanente Washington) with 43 endoscopy centers, 383 eligible physicians, and 735 396 patients aged 50 to 75 years who received a colonoscopy that did not detect cancer (negative colonoscopy) between January 2011 and June 2017, with patient follow-up through December 2017.ExposuresThe adenoma detection rate of each patient's physician based on screening examinations in the calendar year prior to the patient's negative colonoscopy. Adenoma detection rate was defined as a continuous variable in statistical analyses and was also dichotomized as at or above vs below the median for descriptive analyses.Main outcomes and measuresThe primary outcome (postcolonoscopy colorectal cancer) was tumor registry-verified colorectal adenocarcinoma diagnosed at least 6 months after any negative colonoscopy (all indications). The secondary outcomes included death from postcolonoscopy colorectal cancer.ResultsAmong 735 396 patients who had 852 624 negative colonoscopies, 440 352 (51.6%) were performed on female patients, median patient age was 61.4 years (IQR, 55.5-67.2 years), median follow-up per patient was 3.25 years (IQR, 1.56-5.01 years), and there were 619 postcolonoscopy colorectal cancers and 36 related deaths during more than 2.4 million person-years of follow-up. The patients of physicians with higher adenoma detection rates had significantly lower risks for postcolonoscopy colorectal cancer (hazard ratio [HR], 0.97 per 1% absolute adenoma detection rate increase [95% CI, 0.96-0.98]) and death from postcolonoscopy colorectal cancer (HR, 0.95 per 1% absolute adenoma detection rate increase [95% CI, 0.92-0.99]) across a broad range of adenoma detection rate values, with no interaction by sex (P value for interaction = .18). Compared with adenoma detection rates below the median of 28.3%, detection rates at or above the median were significantly associated with a lower risk of postcolonoscopy colorectal cancer (1.79 vs 3.10 cases per 10 000 person-years; absolute difference in 7-year risk, -12.2 per 10 000 negative colonoscopies [95% CI, -10.3 to -13.4]; HR, 0.61 [95% CI, 0.52-0.73]) and related deaths (0.05 vs 0.22 cases per 10 000 person-years; absolute difference in 7-year risk, -1.2 per 10 000 negative colonoscopies [95%, CI, -0.80 to -1.69]; HR, 0.26 [95% CI, 0.11-0.65]).Conclusions and relevanceWithin 3 large community-based settings, colonoscopies by physicians with higher adenoma detection rates were significantly associated with lower risks of postcolonoscopy colorectal cancer across a broad range of adenoma detection rate values. These findings may help inform recommended targets for colonoscopy quality measures.

Project description:Women 50-65 years of age have the lowest cervical and colorectal cancer (CRC) screening rates among ages recommended for screening. The primary aim of this work is to determine how cancer risk perceptions and provider communication behaviors, in addition to known demographic factors, influence the uptake of both cervical and CRC screening or a single screen among women in southeast Michigan. Fourteen health services and communication behavior questions were adapted from the Health Information National Trends Survey (HINTS) and administered to a multiethnic sample of adults in southeast Michigan. The outcome variable was self-reported up-to-date cervical cancer and/or CRC screening as defined by the United States Preventive Services Task Force (USPSTF). Demographic and cancer risk/communication behavior responses of the four screening populations (both tests, one test, no tests) were analyzed with multinomial regression for all comparisons. Of the 394 respondents, 54% were up to date for both cervical and CRC screening, 21% were up to date with only cervical cancer screening and 12% were up to date for only CRC screening. Of the 14 risk perception and communication behavior questions, only 'Did your primary care physician (PCP) involve you in the decisions about your health care as much as you wanted?' was significantly associated with women having both screens compared to only cervical cancer screening (aOR 1.67; 95% CI: 1.08, 2.57). The multivariate model showed age, and Middle East and North African (MENA) ethnicity and Black race, in addition to PCP-patient dyad decision-making to be associated with the cancer screenings women completed. Optimizing PCP-patient decision-making in health care may increase opportunities for both cervical cancer and CRC screening either in the office or by self-sampling. Understanding the effects of age and the different interventional strategies needed for MENA women compared to Black women will inform future intervention trials aimed to increase both cancer screenings.
