A Patient Portal Tool, E-assist, for Supporting CRC Screening

ABSTRACT: To compare patient perceptions, intent to screen, and screening use among those using a patient portal with and without a colorectal cancer (CRC) screening decision support tool, e-assist. To evaluate whether the effectiveness of e-assist is moderated by multi-level factors, including patient health literacy, decision-making preference, and CRC screening decision stage. To assess program impact and create an implementation guide for e-assist by combining results from Aims 1 & 2, a program implementation analysis/process evaluation and the perspectives of staff from future diverse implementation sites including small primary care practices, University-based primary practices and federally-qualified health centers.

Project description:We will investigate the clinical implementation of genome sequencing (GS) for carrier screening to aid reproductive decision-making in adults. The study is organized into three inter-related Projects. The study population will include women and their partners who receive pre-conception testing. In Project 1, we will conduct a Randomized Clinical Trial to test clinical implementation of WGS compared with usual care. We will integrate WGS results with the electronic medical record (EMR), and measure outcomes from patient and physician perspectives. In Project 2, we will perform whole genome sequencing, including validation and interpretation of the identified variants to identify "actionable variants", meaning variants deemed worthy of reporting. This will include a robust approach using a Return of Results Committee (RORC) for determination of reportable results. In Project 3, we will evaluate the ethical and psychosocial implications of expanded carrier screening using WGS for the return of carrier status and secondary findings, and measure the impact on downstream healthcare utilization and cost. Two groups of women are identified through the electronic medical record. The first group has a clinical carrier screening test, usually Cystic Fibrosis (CF), ordered and completed as part of a preconception planning visit. The second group has a carrier screening test, usually CF, performed during pregnancy, they have delivered their baby and are planning a future pregnancy. Eligible women are randomized to either usual care or genome sequencing (GS). Women randomized into the usual care arm have already received their clinical genetic test. These women will not receive genome sequencing. Women in the GS arm will receive their carrier status results for about 700 gene/condition pairs approximately three months after randomization. If there are results to return, women come in for a genetic counseling session. If there are no results, a letter is sent in the mail. Incidental findings (IF) are returned about one month later. As with the carrier status results, all IF are returned in person, and if there are no results a letter is sent in the mail. If a participant is found to be a carrier of an autosomal recessive condition, her male partner is then eligible and invited to participate in the study and receive GS.

Project description:Colorectal cancer (CRC) is the third leading cause of cancer mortality in Switzerland, and kills 1600 people annually. Most deaths could be prevented by screening, but the 2012 Swiss national health survey found that only 40% of 50-75-year-olds had been tested within recommended intervals (26% with colonoscopy in the last 10 year, 7% with fecal occult blood test [FOBT] in the last 2 years, and 7% with both). If screening starts at age 50, in the average risk population absolute risk of dying from CRC at age 80 can be cut from 2% to 1%, reducing relative risk by 50%. Since 2013, Switzerland has reimbursed screening by colonoscopy every 10 years or FOBT every 2 years for adults 50-69 years old. Conforming to current recommendations, the Federal Office of Public Health (FOPH) officially recognizes both screening modalities. When patients are offered a choice of screening test (colonoscopy vs. FOBT), they are as likely to opt for one as the other. Patient preferences are unlikely to vary much between PCP practices, so distribution of colonoscopy and FOBT within each practice should also be roughly equal. Family physicians are recognized as the most trusted professional to discuss CRC screening in Switzerland. However, many primary care physicians (PCPs) prefer prescribing colonoscopy over FOBT, but physician preference for method seems to vary widely between regions. If physician preferences and local medical culture currently influence choice of method more strongly than patient preferences, encouraging PCPs to diagnose patient preferences for screening method may reduce the number of PCPs who prescribe only one method. An earlier study in Switzerland showed that training PCPs and giving them educational support and decision aids raised the number who intend to prescribe colonoscopy and FOBT in equal proportions. A randomized controlled trial in the US showed that when patients were offered both FOBT and colonoscopy rather than only colonoscopy alone, more patients were screened for CRC. Offering choice of method may thus increase overall screening rates. The Swiss Sentinel Surveillance Network (Sentinella) is a cooperative surveillance project including the Federal Office of Public Health (FOPH), PCPs representatives and the five Swiss institutes of family medicine. A sample of 150 to 250 general practitioners, internists and pediatricians in private practices from all regions of Switzerland report weekly morbidity data to the network using irreversibly anonymized patient data collected during consultations. In 2017, 91 out of 129 eligible PCPs of the Sentinella network participated in a cross-sectional data collection on CRC screening. The Sentinella network appears ideally suited to perform an intervention in order to modify screening practices and measure outcomes using the same collection form as in 2017. This study will test the benefits of a prepackaged training program in participatory medicine sent by post to PCPs in Switzerland. The package is designed to improve their diagnoses of patient preferences for screening and screening method (colonoscopy or FOBT). The study begins with the hypothesis that giving PCPs evidence summaries on CRC screening, decision aids for patients, and performance feedback on the 2017 data collection will increase the number of PCPs whose patients include at least one screened with FOBT, and who will prescribe at least one FOBT/FIT (Fecal Immunochemical Test) instead of prescribing only colonoscopy. This might reduce variation in care between PCP practices by increasing variation in methods of screening prescribed within each PCP practices. Analyses from the 2017 data collection suggest that fewer patients refused CRC testing in practices that offered both methods than in practices that offered only colonoscopy. This intervention might increase screening rates overall, while respecting patient’s autonomy to refuse the test and to be prescribed the test they prefer. The study will compare outcomes among PCPs allocated to the intervention group to those in the control group, and will be measured by collecting anonymous structured patient data on 40 consecutive patients by PCPs and questionnaires filled by PCPs. The study is designed to fit within the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework for structuring data collection. RE-AIM ensures that a study’s outcomes for future implementation and dissemination works are collected. The RE-AIM criteria will be used to identify the translatability and public health impact of this intervention, and for making clear to future stakeholders the internal and external validity of study results.

Project description:Pancreatic ductal adenocarcinoma (PDAC) suffers from lack of an effective diagnostic method, limiting improvement in patient survival. Although the FDA-approved biomarker CA19-9 has been used for detection and surveillance of PDAC, its clinical utility is generally regarded to be limited due to its suboptimal diagnostic performance. Liquid chromatography-mass spectrometry (LC-MS) has emerged as a burgeoning technology in clinical proteomics, and identified a plethora of protein biomarker candidates for PDAC. Yet few if any has successfully transitioned into clinical practice. This translational standstill is owed partly to the limited considerations of practical needs and perspectives of clinical implementation in the course of a biomarker pipeline, such as demonstrating analytical validity of proposed biomarkers, which is critical to turning research-grade assays to clinical-grade tests. Here, we developed a fit-for-purpose multi-marker panel for PDAC diagnosis by consolidating analytically robust biomarkers as well as employing a relatively simple LC-MS method. In the discovery phase, we systematically collected putative biomarkers from both in-house proteomics data and the large volume of literature documenting PDAC biomarkers. In the verification phase, we developed a multiple-reaction monitoring (MRM)-MS-based proteomic assay using surrogate peptides that passed stringent analytical validation criteria. Given the intended use of our panel (i.e., primary screening), we adopted a high-throughput protocol including short gradient (<10 min) and simple sample preparation (no depletion or enrichment steps). To further facilitate clinical implementation, we performed verification of our panel on serum samples, which are usually the preferred biospecimen available in clinical settings. We developed a stacking ensemble model based on our final panel of 12 protein biomarkers combined with CA19-9, which showed improved diagnostic performance compared to using CA19-9 alone (AUC 0.919 and 0.830, respectively). A large-scale clinical validation study is underway to demonstrate the clinical validity of our panel.
