Cancer Screening: Provider Incentives — Breast Cancer

The CPSTF finding is based on evidence from a Community Guide systematic review published in 2008 (Sabatino, et al., search period through September 2004) combined with more recent evidence (search period 2004 – October 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: Provider Incentives Breast Cancer.

The effectiveness of provider-directed interventions was determined by considering evidence across all three cancer screening sites combined, as long as there were not differences in effectiveness by screening test. This was done because provider behavior was thought to be less influenced than client behavior by the nature of screening tests.

Detailed results from the systematic review are available in the CPSTF Finding and Rationale Statement

The review included five studies that assessed intervention effectiveness for breast, cervical, and colorectal cancers.

• Screening completion for breast, cervical or colorectal cancer: median increase of 1.7 percentage points (interquartile interval [IQI]: 0.1 to 3.6 percentage points; 7 study arms)
• Completed breast cancer screening by mammography: estimated effects ranged from a 2.0 percentage point decrease to a 1.7 percentage point increase (2 study arms)

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

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

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 reviews of provider incentives to increase breast, cervical, and colorectal cancer screening.

The effectiveness of provider incentives in increasing colorectal, breast, and cervical cancer screening has not been established. Despite great interest in and use of provider incentives in many organized health systems (e.g., pay-for-performance models), relatively little published scientific information is available to assess the effectiveness of incentives in increasing screening for breast, cervical, and colorectal cancers. Several research questions remain.

• Are provider incentives effective in increasing screening for colorectal, breast, and cervical cancers?
• Do provider incentives incrementally increase the effectiveness of provider assessment and feedback interventions?
• What are the most cost-effective approaches to reward cancer screening performance and/or referral by practitioners?
• Do these interventions result in other positive or negative changes in health behavior or use of healthcare services?
• 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?

• Physician settings ranged from large, multi-specialty organizations to individual practice associations or physician practices.
• Included studies reported completed screenings, recommended or offered screenings, or both.
• Studies that reported completed screenings used medical records, self-report, or performance reports to measure outcomes.
• Interventions included provider incentives alone or with provider assessment and feedback and reminders.
• Incentives varied across studies.

Effectiveness Review

Analytic Framework see Figure 3 on page 101

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.

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.

The 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.
