A Qualitative Analysis of Barriers to Colorectal Cancer Screening among Korean Americans

Assessing Fear, Embarrassment, and Disgust in Colonoscopy: The Development of Measurement Instruments and Psychometric Evidence

BACKGROUND

Avoidance of colonoscopy is often associated with fear, embarrassment, and disgust aroused in screening procedures. However, each emotion can be linked to different challenges faced by patients. More research is needed to evaluate and address the causes of these respective emotions.

AIM

The purpose of this study was to develop and assess the scales of three negative emotions (i.e., fear, embarrassment, and disgust) caused by specific issues in colonoscopy screening.

METHOD

The measurement items were developed based on multiple common barriers in colonoscopy screening procedures. An online sample of 232 adults aged 45-75 was recruited from Amazon Mechanical Turk to test the scales. Explorative and confirmatory factor analyses were conducted to validate the measurement models.

RESULTS

Psychometric evidence demonstrated the factor structures of three negative emotions. Each emotional factor was caused by unique combinations of barriers in the preparation, screening, and recovery stages of colonoscopy. Most of the emotional factors were associated with attitudes and screening intention.

CONCLUSION

This study showed different dimensions of negative emotions and their underlying causes in colonoscopy. These findings will help assess specific causes of negative emotions in colonoscopy and develop effective interventions to improve screening uptake.

Social determinants and participation in fecal occult blood test based colorectal cancer screening: A qualitative systematic review and meta-synthesis

ISSUE ADDRESSED

Colorectal cancer (CRC) screening through fecal occult blood testing (FOBT) has saved thousands of lives globally with multiple countries adopting comprehensive population wide screening programs. Participation rates in FOBT based CRC screening for the socially and economically disadvantaged remains low. The aim of this systematic review is to explore empirical evidence that will guide targeted interventions to improve participation rates within priority populations.

METHODS

PubMed, Embase, Scopus, Cinahl and PsycInfo were systematically searched from inception to 22 June 2022. Eligible studies contained qualitative evidence identifying barriers to FOBT based CRC screening for populations impacted by the social determinants of health. An inductive thematic synthesis approach was applied using grounded theory methodology, to explore descriptive themes and interpret these into higher order analytical constructs and theories.

RESULTS

A total of 8,501 publications were identified and screened. A total of 48 studies from 10 countries were eligible for inclusion, representing 2,232 subjects. Coding within included studies resulted in 30 key descriptive themes with a thematic frequency greater than 10%. Coded themes applied to four overarching, interconnected barriers driving inequality for priority populations: social, behavioural, economic and technical/interfaces. SO WHAT?: This study has highlighted the need for stronger patient/provider relationships to mitigate barriers to FOBT screening participation for diverse groups. Findings can assist health professionals and policy makers address the systemic exclusion of priority populations in cancer screening by moving beyond the responsibility of the individual to a focus on addressing the information asymmetry driving low value perceptions.

Fatalism and metaphor in Confucianism: A qualitative study of barriers to genetic testing among first-degree relatives of hereditary cancer patients from China

OBJECTIVE

Despite the benefits, the rate of genetic testing among first-degree relatives (FDRs; parents, children, and siblings) remains low, and the barriers to undergoing testing among FDRs in China are not clear. We explored the reasons why FDRs refused genetic testing.

METHODS

Semi-structured face-to-face interviews were conducted with 22 patients and 27 FDRs. Participants were recruited at an urban tertiary hospital in Guangzhou, South China. We used qualitative content analysis to analyse the transcripts of audio recordings and identify major themes and subthemes.

RESULTS

Three major themes emerged related to FDRs' low rate of participation in genetic testing. First, there is cognitive distance from genetic testing/cancer and a lack of knowledge of preventive medicine that deepens the 'fatalistic' attitude towards cancer among FDRs, which leads to an enormous gap between their knowledge and understanding of genetic testing. Second, medical consultation is not valued in Confucianism, and the view of cancer as 'bad news' and the risk of cancer as a curse makes cancer a metaphor, which leads to exhausting arguments when persuading FDRs to undergo genetic testing. Third, physical distance from the hospital, loss of privacy, possible discrimination in many social activities and genetic testing as a source of stress and anxiety lead FDRs to fear the disruption of their daily lives.

CONCLUSIONS

There are many barriers to genetic testing among the FDRs of hereditary cancer patients originating from the national social and cultural context. Healthcare professionals should develop interventions rooted in culture and promote cancer risk communication between hereditary cancer patients and FDRs.

Barriers to Colorectal Cancer Screening in US Immigrants: A Scoping Review

INTRODUCTION

Timely colorectal cancer (CRC) screening has been shown to improve CRC-related morbidity and mortality rates. However, even with this preventative care tool, CRC screening rates remain below 70% among eligible United States (US) adults, with even lower rates among US immigrants. The aim of this scoping review is to describe the barriers to CRC screening faced by this unique and growing immigrant population and discuss possible interventions to improve screening.

METHODS

Four electronic databases were systematically searched for all original research articles related to CRC screening in US immigrants published after 2010. Following a full-text review of articles for inclusion in the final analysis, data extraction was conducted while coding descriptive themes. Thematic analysis led to the organization of this data into five themes.

RESULTS

Of the 4637 articles initially identified, 55 met inclusion criteria. Thematic analysis of the barriers to CRC screening identified five unique themes: access, knowledge, culture, trust, health perception, and beliefs. The most cited barriers were in access (financial burden and limited primary care access) and knowledge (CRC/screening knowledge).

CONCLUSIONS

US immigrants face several barriers to the receipt of CRC screening. When designing interventions to increase screening uptake among immigrants, gaps in physician and screening education, access to care, and trust need to be addressed through culturally sensitive supports. These interventions should be tailored to the specific immigrant group, since a one-size-fits approach fails to consider the heterogeneity within this population.

Heterogeneity in the Utilization of Fecal Occult Blood Testing and Colonoscopy among Migrants and Non-Migrants in Austria: Results of the Austrian Health Interview Survey

Many European studies report lower participation in colorectal cancer screening among migrants than non-migrants. A major limitation of these studies is that usually, the heterogeneity of migrants cannot be accounted for. The aim of this investigation was to examine differences in the utilization of fecal occult blood testing and colonoscopy between non-migrants and the five largest migrant groups residing in Austria using data from the Austrian Health Interview Survey 2019. The two outcomes were compared between non-migrants and migrants using multivariable logistic regression adjusted for socioeconomic and health variables. Migrants from a Yugoslav successor state (OR = 0.61; 95%-CI: 0.44–0.83), Turkish (OR = 0.35; 95%-CI: 0.22–0.55), Hungarian (OR = 0.37; 95%-CI: 0.16–0.82) and German migrants (OR = 0.70; 95%-CI: 0.51–0.98) were less likely to have used a fecal occult blood test compared to non-migrants. Participation in colonoscopy was lower among Turkish migrants (OR = 0.42; 95%-CI: 0.27–0.67) and migrants from a Yugoslav successor state (OR = 0.56; 95%-CI: 0.42–0.75) than among non-migrants. The findings are consistent with studies from other countries and highlight barriers migrants face in accessing the health care system. To address these barriers, the heterogeneity of the population must be taken into account when developing educational materials in order to promote informed decisions about whether or not to participate in colorectal cancer screening.

Psychological distance: a qualitative study of screening barriers among first-degree relatives of colorectal cancer patients

BACKGROUND

Colorectal cancer screening can reduce the incidence and mortality through early detection. First-degree relatives (FDRs) of patients with colorectal cancer are at high risk for colorectal cancer and therefore require colonoscopy. However, despite the high risk, screening adherence among FDRs remains low and the barriers to undergoing screening among FDRs in China are not clear. We explored the reasons why FDRs refused screening.

METHODS

In this qualitative study, 28 semistructured, in-depth interviews were conducted face-to-face. Participants were recruited at two hospitals (an urban tertiary hospital and a community health center) in Guangzhou, South China. We used qualitative content analysis to analyze transcripts based on audio recordings and identify major themes and subthemes.

RESULTS

Three major themes emerged related to FDRs' low screening participation. First, the emotional distance between FDRs and medicine was pulled away by uncomfortable feelings approaching hospitals and misunderstanding of cancer. Second, they confirmed their health state and minimized cancer risk if they had no signs in routine health examination, no symptoms and maintained a healthy, happy life. Third, they considered screening far from their daily life from the perspective of spatial distance and priority. Therefore, screening was not necessary in their view.

CONCLUSIONS

Healthcare professionals should narrow psychological distance between people and screening when promoting screening technology.
