Cancer Screening: Group Education for Clients — Colorectal Cancer

Summary of CPSTF Finding

The Community Preventive Services Task Force (CPSTF) finds insufficient evidence to determine the effectiveness of group education in increasing screening for colorectal cancer, based on the small number of studies with methodologic limitations and inconsistent findings.

The CPSTF has related findings for group education specific to the following:

Intervention

Group education conveys information on indications for, benefits of, and ways to overcome barriers to screening with the goal of informing, encouraging, and motivating participants to seek recommended screening. Group education is usually conducted by health professionals or by trained lay people who use presentations or other teaching aids in a lecture or interactive format, and often incorporate role modeling or other methods. Group education can be given to a variety of groups, in different settings, and by different types of educators with different backgrounds and styles.

About The Systematic Review

The CPSTF finding is based on evidence from a Community Guide systematic review published in 2008 (Baron et al., 1 study, search period 1966-2004) combined with more recent evidence (1 study, search period 2004-2008). The systematic review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to cancer prevention and control. This finding updates and replaces the 2008 CPSTF finding on Cancer Screening: Group Education Colorectal Cancer.

Summary of Results

Two studies qualified for the updated systematic review.

Summary of Economic Evidence

An economic review of this intervention was not conducted because CPSTF did not have enough information to determine if the intervention works.

Applicability

Applicability of this intervention across different settings and populations was not assessed because CPSTF did not have enough information to determine if the intervention works.

Evidence Gaps

The CPSTF identified several areas that have limited information. Additional research and evaluation could help answer the following questions and fill remaining gaps in the evidence base. (What are evidence gaps?)

The following outlines evidence gaps for client incentives to increase breast, cervical, or colorectal cancer screening.

  • Are group education interventions that target specific groups more effective in increasing breast, cervical, or colorectal cancer screening within those groups than within untargeted interventions?
  • Does effectiveness vary with intensity of education sessions or specific components included in them?
  • What are the incremental effects of adding intervention components to other interventions?
  • What influence do newer methods of communication (e.g., the Internet, e-mail, social media, automated interactive voice response, texting) have on intervention effectiveness?
  • What is the influence of health system factors on intervention effectiveness?
  • Are interventions effective for promoting colorectal cancer screening with methods other than FOBT?
  • Are interventions to promote colorectal cancer screening equally effective when specific to one type of test as they are when addressing colorectal cancer screening more generally?

Study Characteristics

  • Both studies assessed intervention effects on colorectal cancer screening by FOBT.
  • One study offered interactive group sessions delivered by peer facilitators, and the other offered sessions delivered by promotoras with an in-class format.
  • Populations included Latinas, African Americans, and white Americans.
  • Interventions were delivered in churches or homes in the community.

Analytic Framework

Effectiveness Review

Analytic Framework see Figure 1 on page 100

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

Search Strategies

The following outlines the search strategy used for these reviews of interventions to increase breast, cervical, and colorectal cancer screening: Client Reminders; Client Incentives; Mass Media Targeting Clients; Group Education for Clients; One-on-One Education for Clients; Reducing Structural Barriers for Clients; Reducing Client Out-of-Pocket Costs; Provider Assessment and Feedback; Provider Incentives.

Effectiveness Review

With the assistance of a CDC librarian, the following databases were searched for publications from 2004 up to 2008: Medline (Ovid), CINAHL (Ovid), PsycINFO (Ovid), Cochrane [Cochrane Reviews, Other Reviews, Methods Studies, Technology Assessments, Economic Evaluations], WoS (SSCI only), Chronic Disease Prevention – cancer prevention and control subcategory (no longer exists).

The team considered studies for inclusion if they were human studies conducted in high income economies according to the World Bank, and published in English.

Considerations for Implementation

CPSTF did not have enough evidence to determine whether the intervention is or is not effective. This does not mean that the intervention does not work, but rather that additional research is needed to determine whether or not the intervention is effective.
