Improving uptake of colorectal cancer screening by complex patients at an academic primary care practice: a feasibility study.

BACKGROUND: Regular screening reduces mortality from colorectal cancer (CRC). The Canton of Vaud, Switzerland, has a regional screening programme offering faecal immunochemical tests (FITs) or colonoscopy. Participation in the screening programme has been low, particularly among complex patients. Patient navigation has strong evidence for increasing the CRC screening rate. DESIGN AND OBJECTIVE: This feasibility study tested patient navigation performed by medical assistants for complex patients at an academic primary care practice. BASELINE MEASUREMENTS: A review of 328 patients' medical charts revealed that 51% were up-to-date with screening (16% within the programme), 24% were ineligible, 5% had a documented refusal and 20% were not up-to-date, of whom 58 (18%) were complex patients. INTERVENTION FEBRUARY 2023 TO MAY 2023: We tried to help complex patients participate in the screening programme using either in-person or telephone patient navigation. Each intervention was piloted by a physician-researcher and then performed by a medical assistant. Based on the reach, effectiveness, adoption, implementation, maintenance framework, we collected: Intervention participation and refusal, screening acceptance and completion and both patients and medical assistant acceptability (ie, qualitative interviews). RESULTS: Only 4/58 (7%) patients participated in the in-person patient navigation test phase due to scheduling problems. All four patients accepted a prescription and 2/4 (50%) completed their test. We piloted a telephone intervention to bypass scheduling issues but all patients refused a telephone discussion with the medical assistant. At two months after the last intervention, the proportion of patients up-to-date increased from 51% to 56%. CONCLUSION: Our overall approach was resource-intensive and had little impact on the overall participation rate. It was likely not sustainable. New approaches and reimbursement for a specific patient navigator role are needed to increase CRC screening of complex patients.

An Online Influenza Surveillance System for Primary Care Workers in Switzerland: Observational Prospective Pilot Study.

BACKGROUND: A better understanding of the influenza epidemiology among primary care workers could guide future recommendations to prevent transmission in primary care practices. Therefore, we designed a pilot study to assess the feasibility of using a work-based online influenza surveillance system among primary care workers. Such an approach is of particular relevance in the context of the coronavirus disease (COVID-19) pandemic, as its findings could apply to other infectious diseases with similar mechanisms of transmission. OBJECTIVE: This study aims to determine the feasibility of using a work-based online influenza surveillance system for primary care workers in Switzerland. METHODS: Physicians and staff of one walk-in clinic and two selected primary care practices were enrolled in this observational prospective pilot study during the 2017-2018 influenza season. They were invited to record symptoms of influenza-like illness in a weekly online survey sent by email and to self-collect a nasopharyngeal swab in case any symptoms were recorded. Samples were tested by real-time polymerase chain reaction for influenza A, influenza B, and a panel of respiratory pathogens. RESULTS: Among 67 eligible staff members, 58% (n=39) consented to the study and 53% (n=36) provided data. From the time all participants were included, the weekly survey response rate stayed close to 100% until the end of the study. Of 79 symptomatic episodes (mean 2.2 episodes per participant), 10 episodes in 7 participants fitted the definition of an influenza-like illness case (attack rate: 7/36, 19%). One swab tested positive for influenza A H1N1 (attack rate: 3%, 95% CI 0%-18%). Swabbing was considered relatively easy. CONCLUSIONS: A work-based online influenza surveillance system is feasible for use among primary care workers. This promising methodology could be broadly used in future studies to improve the understanding of influenza epidemiology and other diseases such as COVID-19. This could prove to be highly useful in primary care settings and guide future recommendations to prevent transmission. A larger study will also help to assess asymptomatic infections.
