Using Facebook to promote the uptake of colorectal cancer screening

Application of the 'online assessment + FOBT at home' to improve participation and the efficacy of opportunistic screening for colorectal cancer: a retrospective cohort study

BACKGROUND

Colorectal cancer (CRC) screening faces two major challenges: insufficient screening coverage and poor adherence. A smartphone applet named "Early Screening Assistant (ESA)" was developed to create an online risk-assessment and fecal occult blood test (FOBT) at home. This retrospective study was designed to evaluate whether the new CRC screening strategy can improve the colonoscopy participation rate (PR) and lesion detection rate (DR).

METHODS

In total, 6194 individuals who accepted normal health examinations and CRC screening based on the ESA from June 2020 to May 2022 were assigned to the ESA group. Accordingly, 7923 inhabitants who only accepted normal health examinations were assigned to the control group. The colonoscopy PR and neoplastic lesion DR were then compared between the two groups.

RESULTS

Overall, a higher proportion of subjects in the ESA group (285 of 6194 [4.6%]) completed colonoscopy than in the control group (126 of 7923, [1.6%]), p < 0.01). The neoplastic lesion DR also significantly increased in the ESA group (76 of 6194 [1.22%]) compared with the control group (15 of 7923 [0.19%]) (p < 0.01). The adjusted diagnostic sensitivity and specificity of the "Online assessment + FOBT at home" were 41.5% and 62.6% for neoplastic lesions, respectively.

CONCLUSIONS

This retrospective cohort study confirmed that the new CRC screening strategy based on the "Online assessment + FOBT at home" can improve colonoscopy participation and the neoplastic lesion detection rate and may represent a promising screening strategy for CRC.

Scandinavian Nurses’ Use of Social Media during the COVID-19 Pandemic—A Berger and Luckman Inspired Analysis of a Qualitative Interview Study

There is a knowledge gap about nurses’ use of social media in relation to and during the COVID-19 pandemic, which demands the upholding of a physical distance to other people, including patients and their relatives. The study aims to explore how nurses in the Scandinavian countries used social media for professional purposes in relation to the first 15 months of the COVID-19 pandemic. Qualitative, semi-structured interviews with 30 nurses in three Scandinavian countries (Denmark, Norway, and Sweden) were conducted. Thematic analyses were made, methodically inspired by Braun and Clarke, and theoretically inspired by Berger and Luckmann’s theory about the construction of social reality. The Standards for Reporting Qualitative Research (SRQR) checklist was used. The results showed that social media was a socialisation tool for establishing new routines in clinical practice. Virtual meeting places supported collective understandings of a specific COVID-19 ‘reality’ and ‘knowledge’ amongst nurses, with the pandemic bringing to the fore the issue of e-professionalism among nurses relating to their clinical practice. However, social media and virtual education were not commonly used in patient contacts. Further, nurses attempted a re-socialisation of the public to proper COVID-19 behaviour through social media. Moreover, blurred boundaries between acting as a private individual and a professional nurse were identified, where ethics of the nursing profession extended to nurses’ private lives.

COVID-19 Vaccine Communication via Chatbot: A Qualitative Study on Message Preferences of Young Adults and Public Health Workers in Urban American Communities

Background

Automated conversational agents, or chatbots, have a role in reinforcing evidence-based guidance delivered through other media and offer an accessible, individually tailored channel for public engagement. In early-to-mid 2021, young adults and minority populations disproportionately affected by COVID-19 in the United States were more likely to be hesitant toward COVID-19 vaccines, citing concerns regarding vaccine safety and effectiveness. Successful chatbot communication requires purposive understanding of user needs.

Objective

We aimed to review the acceptability of messages to be delivered by a chatbot named VIRA from Johns Hopkins University. The study investigated which message styles were preferred by young, urban-dwelling Americans as well as public health workers, since we anticipated that the chatbot would be used by the latter as a job aid.

Methods

We conducted 4 web-based focus groups with 20 racially and ethnically diverse young adults aged 18-28 years and public health workers aged 25-61 years living in or near eastern-US cities. We tested 6 message styles, asking participants to select a preferred response style for a chatbot answering common questions about COVID-19 vaccines. We transcribed, coded, and categorized emerging themes within the discussions of message content, style, and framing.

Results

Participants preferred messages that began with an empathetic reflection of a user concern and concluded with a straightforward, fact-supported response. Most participants disapproved of moralistic or reasoning-based appeals to get vaccinated, although public health workers felt that such strong statements appealing to communal responsibility were warranted. Responses tested with humor and testimonials did not appeal to the participants.

Conclusions

To foster credibility, chatbots targeting young people with vaccine-related messaging should aim to build rapport with users by deploying empathic, reflective statements, followed by direct and comprehensive responses to user queries. Further studies are needed to inform the appropriate use of user-customized testimonials and humor in the context of chatbot communication.
