Multidisciplinary teams and social science: a patient perspective.

Multidisciplinary teams (MDTs) are common in colorectal cancer and have been deemed important when providing care. Yet they take place outside of the patient, often with little consideration of the patient's views, goals and desires. In this paper specific examples from a patient perspective are integrated with the social science literature to provide an overview of areas of disconnect between MDT recommendations and the individual patient. The reasons for these disconnects are explored, including how MDTs relate to dyadic patient-clinician relationships, weak incorporation of patient-oriented outcomes in MDTs, poor integration of nonmedical patient information and the patient perspective and the impact of team dynamics and cognitive decision biases. Consideration of these issues should facilitate higher-quality MDT recommendations that are also more acceptable to patients.

Experiences and perspectives of colorectal cancer survivors and general practitioners on the delivery of survivorship care in general practice: a mixed methods study.

BACKGROUND: Many colorectal cancer (CRC) survivors experience ongoing sequelae from their cancer treatment. Limited evidence exists regarding how CRC survivors and general practitioners (GPs) manage these sequelae in the community. This study aimed to explore the experiences and perspectives of CRC survivors and GPs on current approaches to monitoring and managing sequelae of CRC treatment. METHODS: We conducted a mixed-methods study using cross-sectional national surveys and qualitative interviews with CRC survivors and GPs to explore: (1) treatment sequelae experienced by CRC survivors, (2) how these were monitored and managed by general practitioners, and (3) suggestions to improve ongoing management of the treatment sequelae. Survey responses were reported descriptively. Qualitative data were thematically analysed using an interpretive descriptive approach. RESULTS: Seventy participants completed surveys: 51 CRC survivors and 19 GPs, and four interviews were conducted with GPs. CRC survivors experienced a range of treatment sequelae, but often did not discuss these with their GPs (experienced vs discussed: 86% vs 47% for fatigue/lack of energy, 78% vs 27% for psychological/emotional concern, 63% vs 22% for impaired sleep, 69% vs 29% for weight loss/gain, 59% vs 16% for sexual and intimacy concerns). GPs reported inadequate information transfer from cancer services and workload as major barriers to optimal care. CONCLUSIONS: System-level changes that facilitate adequate information transfer from cancer services to GPs upon CRC treatment completion, as well as addressing time constraint issues essential for comprehensive monitoring and management of CRC treatment sequelae, could enhance the care of CRC survivors in the community setting.

Engineering tumor-colonizing E. coli Nissle 1917 for detection and treatment of colorectal neoplasia.

Bioengineered probiotics enable new opportunities to improve colorectal cancer (CRC) screening, prevention and treatment. Here, first, we demonstrate selective colonization of colorectal adenomas after oral delivery of probiotic E. coli Nissle 1917 (EcN) to a genetically-engineered murine model of CRC predisposition and orthotopic models of CRC. We next undertake an interventional, double-blind, dual-centre, prospective clinical trial, in which CRC patients take either placebo or EcN for two weeks prior to resection of neoplastic and adjacent normal colorectal tissue (ACTRN12619000210178). We detect enrichment of EcN in tumor samples over normal tissue from probiotic-treated patients (primary outcome of the trial). Next, we develop early CRC intervention strategies. To detect lesions, we engineer EcN to produce a small molecule, salicylate. Oral delivery of this strain results in increased levels of salicylate in the urine of adenoma-bearing mice, in comparison to healthy controls. To assess therapeutic potential, we engineer EcN to locally release a cytokine, GM-CSF, and blocking nanobodies against PD-L1 and CTLA-4 at the neoplastic site, and demonstrate that oral delivery of this strain reduces adenoma burden by ~50%. Together, these results support the use of EcN as an orally-deliverable platform to detect disease and treat CRC through the production of screening and therapeutic molecules.

Eyes on incivility in surgical teams: Teamwork, well-being, and an intervention.

Incivility in surgery is prevalent and negatively impacts effectiveness and staff well-being. The purpose of this study was to a) examine relationships between incivility, team dynamics, and well-being outcomes, and b) explore a low-cost intervention of 'eye' signage in operating theater areas to reduce incivility in surgical teams. A mixed methods design was used in an orthopedic hospital. Surveys of incivility, teamwork, and well-being were administered three months apart in a small private hospital. An intervention of signage with eyes was placed in the theater area after administration of the first survey, using a pretest-posttest design. Participants also responded to an open-ended question about suggestions for improvements at the end of the survey which was then thematically analyzed. At the individual level (n = 74), incivility was statistically significantly related to team dynamics which in turn was significantly related to burnout, stress, and job attitudes. At the aggregate level, reported incivility was statistically significantly lower after the 'eye' sign intervention. Thematic analysis identified core issues of management behaviors, employee appreciation, communication, and work practices. Incivility in surgical teams has significant detrimental associations with burnout, stress, and job attitudes, which occurs through its impact on decreased team dynamics and communication. A simple intervention that evokes perceptions of being observed, such as signage of eyes in theater areas, has the potential to decrease incivility at least in the short term, demonstrating that incivility is amenable to being modified. Additional research on targeted interventions to address incivility are needed to improve teamwork and staff well-being.

Colorectal cancer detection and treatment with engineered probiotics.

Bioengineered probiotics enable new opportunities to improve colorectal cancer (CRC) screening, prevention and treatment strategies. Here, we demonstrate the phenomenon of selective, long-term colonization of colorectal adenomas after oral delivery of probiotic E. coli Nissle 1917 (EcN) to a genetically-engineered murine model of CRC predisposition. We show that, after oral administration, adenomas can be monitored over time by recovering EcN from stool. We also demonstrate specific colonization of EcN to solitary neoplastic lesions in an orthotopic murine model of CRC. We then exploit this neoplasia-homing property of EcN to develop early CRC intervention strategies. To detect lesions, we engineer EcN to produce a small molecule, salicylate, and demonstrate that oral delivery of this strain results in significantly increased levels of salicylate in the urine of adenoma-bearing mice, in comparison to healthy controls. We also assess EcN engineered to locally release immunotherapeutics at the neoplastic site. Oral delivery to mice bearing adenomas, reduced adenoma burden by ∻50%, with notable differences in the spatial distribution of T cell populations within diseased and healthy intestinal tissue, suggesting local induction of robust anti-tumor immunity. Together, these results support the use of EcN as an orally-delivered platform to detect disease and treat CRC through its production of screening and therapeutic molecules.

Experiences of colorectal cancer survivors in returning to primary coordinated healthcare following treatment.

BACKGROUND: Advances in screening and treatments for colorectal cancer (CRC) have improved survival rates, leading to a large population of CRC survivors. Treatment for CRC can cause long-term side-effects and functioning impairments. General practitioners (GPs) have a role in meeting survivorship care needs of this group of survivors. We explored CRC survivors' experiences of managing the consequences of treatment in the community and their perspective on the GP's role in post-treatment care. METHODS: This was a qualitative study using an interpretive descriptive approach. Adult participants no longer actively receiving treatment for CRC were asked about: side-effects post-treatment; experiences of GP-coordinated care; perceived care gaps; and perceived GP role in post-treatment care. Thematic analysis was used for data analysis. RESULTS: A total of 19 interviews were conducted. Participants experienced side-effects that significantly impacted their lives; many they felt ill-prepared for. Disappointment and frustration was expressed with the healthcare system when expectations about preparation for post-treatment effects were not met. The GP was considered vital in survivorship care. Participants' unmet needs led to self-management, self-directed information seeking and sourcing referral options, leaving them feeling like their own care coordinator. Disparities in post-treatment care between metropolitan and rural participants were observed. CONCLUSION: There is a need for improved discharge preparation and information for GPs, and earlier recognition of concerns following CRC treatment to ensure timely management and access to services in the community, supported by system-level initiatives and appropriate interventions.

The SCRIPT trial: study protocol for a randomised controlled trial of a polygenic risk score to tailor colorectal cancer screening in primary care.

BACKGROUND: Polygenic risk scores (PRSs) can predict the risk of colorectal cancer (CRC) and target screening more precisely than current guidelines using age and family history alone. Primary care, as a far-reaching point of healthcare and routine provider of cancer screening and risk information, may be an ideal location for their widespread implementation. METHODS: This trial aims to determine whether the SCRIPT intervention results in more risk-appropriate CRC screening after 12 months in individuals attending general practice, compared with standard cancer risk reduction information. The SCRIPT intervention consists of a CRC PRS, tailored risk-specific screening recommendations and a risk report for participants and their GP, delivered in general practice. Patients aged between 45 and 70 inclusive, attending their GP, will be approached for participation. For those over 50, only those overdue for CRC screening will be eligible to participate. Two hundred and seventy-four participants will be randomised to the intervention or control arms, stratified by general practice, using a computer-generated allocation sequence. The primary outcome is risk-appropriate CRC screening after 12 months. For those in the intervention arm, risk-appropriate screening is defined using PRS-derived risk; for those in the control arm, it is defined using family history and national screening guidelines. Timing, type and results of the previous screening are considered in both arms. Objective health service data will capture screening behaviour. Secondary outcomes include cancer-specific worry, risk perception, predictors of CRC screening behaviour, screening intentions and health service use at 1, 6 and 12 months post-intervention delivery. DISCUSSION: This trial aims to determine whether a PRS-derived personalised CRC risk estimate delivered in primary care increases risk-appropriate CRC screening. A future population risk-stratified CRC screening programme could incorporate risk assessment within primary care while encouraging adherence to targeted screening recommendations.
