Evaluating preferences for colorectal cancer screening in individuals under age 50 using the Analytic Hierarchy Process

Patient Preferences in Diagnostic Imaging: A Scoping Review

BACKGROUND

As new diagnostic imaging technologies are adopted, decisions surrounding diagnostic imaging become increasingly complex. As such, understanding patient preferences in imaging decision making is imperative.

OBJECTIVES

We aimed to review quantitative patient preference studies in imaging-related decision making, including characteristics of the literature and the quality of the evidence.

METHODS

The Pubmed, Embase, EconLit, and CINAHL databases were searched to identify studies involving diagnostic imaging and quantitative patient preference measures from January 2000 to June 2022. Study characteristics that were extracted included the preference elicitation method, disease focus, and sample size. We employed the PREFS (Purpose, Respondents, Explanation, Findings, Significance) checklist as our quality assessment tool.

RESULTS

A total of 54 articles were included. The following methods were used to elicit preferences: conjoint analysis/discrete choice experiment methods (n = 27), contingent valuation (n = 16), time trade-off (n = 4), best-worst scaling (n = 3), multicriteria decision analysis (n = 3), and a standard gamble approach (n = 1). Half of the studies were published after 2016 (52%, 28/54). The most common scenario (n = 39) for eliciting patient preferences was cancer screening. Computed tomography, the most frequently studied imaging modality, was included in 20 studies, and sample sizes ranged from 30 to 3469 participants (mean 552). The mean PREFS score was 3.5 (standard deviation 0.8) for the included studies.

CONCLUSIONS

This review highlights that a variety of quantitative preference methods are being used, as diagnostic imaging technologies continue to evolve. While the number of preference studies in diagnostic imaging has increased with time, most examine preventative care/screening, leaving a gap in knowledge regarding imaging for disease characterization and management.

Preferences for Colorectal Cancer Screening Modalities Among the General Population in Saudi Arabia

BACKGROUND

Colorectal cancer (CRC) could be a leading explanation for cancer-related death. Numerous studies have shown the benefit of early screening for colorectal cancer in reducing mortality. Screening for colorectal cancer is a rational and cost-effective strategy for reducing the incidence of colorectal cancer and related mortality. Despite endorsement by academic and healthcare organizations, patient awareness and compliance with screening are low, partly due to patient-related barriers to screening.

AIM

This study aimed to explore the preferred screening method for colorectal cancer in Saudi Arabia in general.

METHODS

This is a cross-sectional study conducted among the Saudi adult population from September 2021 through February 2022. A self-developed questionnaire was distributed among the population using an online platform. Data were tabulated in Google Forms, and all statistical analyses were performed using SPSS version 26 (IBM Corp., Armonk, NY).

RESULTS

During this study, data from 10,781 participants were analyzed. Among them, the most preferred screening modality for colorectal cancer was the stool fecal immunochemical test (41.7%) and the most suitable (33.5%). The most commonly mentioned qualities that influenced choosing a particular screening test were "how the test was performed" (50.4%).

CONCLUSION

Because the stool fecal immunochemical test is the most preferred screening modality for colorectal cancer, this study could serve as a database to aid in the implementation of a colorectal cancer screening program that meets the preferences of the general population of Saudi Arabia.

Colorectal cancer knowledge and perceptions among individuals below the age of 50

BACKGROUND

Colorectal cancer (CRC) rates are increasing in individuals below the age of 50 and this trend has been projected to continue for the foreseeable future. Health officials are calling for increased awareness of rising rates in affected populations to promote discussion and early detection.

METHODS

In May 2018, we surveyed an online purposive sample of adults below the age of 50 (N = 624). We conducted an exploratory analysis examining knowledge of current CRC screening guidelines, knowledge of available CRC screening methods, perceived risk of CRC, and perceived importance of screening for CRC by gender, race, and previous CRC screening activity.

RESULTS

The sample was 56% female, averaged 36 years of age, largely identified as Caucasian (84%), married (48%), and well educated (70% with some college or a college degree). 36% correctly identified the current age of recommended CRC screening initiation. Few (8%) correctly identified all CRC screening options presented. Genetics was thought to be the most relevant determinant of CRC. African American or black participants perceived themselves to be at lower risk of CRC, while women rated the importance of screening significantly lower than men.

CONCLUSION

We identified a lack of CRC knowledge in individuals below the age of 50. Interventions should correct perceptions of risk of CRC and highlight the importance of screening. Complete knowledge of the range of screening options may reduce barriers to screening while a greater knowledge of modifiable risk factors of CRC can promote healthy behaviors.
