Report Suggests Spaced Education Intervention Decreases Inappropriate Prostate Cancer Screening among Veterans


BACKGROUND:
None of the major clinical practice guidelines (CPGs) recommend that prostate cancer screening with prostate-specific antigen (PSA) be routinely performed in asymptomatic males <40 years of age, >75 years of age, or with less than a 10-year life expectancy. And in 2008, the U.S. Preventive Services Task Force revised its guidelines to recommend specifically against PSA screening in men 75 years and older. This study tested an e-mail-based intervention called “spaced education” that was developed to reduce clinicians’ inappropriate screening for prostate cancer. Each of the spaced education (SE) e-mails presented a clinical scenario and asked whether a PSA test was appropriate; each one also contained an answer and explanation. Investigators randomized 95 primary care clinicians at eight VAMCs in the New England region into two groups: the spaced education group, in which clinicians received four cycles of nine e-mails over 36 weeks; and the control group, in which clinicians received no intervention. The trial was conducted from 1/07 to 2/09, with the primary outcome measure being the difference in the percentage of inappropriate PSA screening performed by VA clinicians participating in the intervention with those in the control group.

FINDINGS:

  • During the intervention period (36 weeks), clinicians who received the spaced education intervention ordered significantly fewer inappropriate PSA screening tests than clinicians in the control group (11% vs. 14%). Over the 72-week follow-up period, SE clinicians continued to order fewer inappropriate tests compared to controls (8% vs. 13%), representing a 40% relative reduction in inappropriate screening.
  • The impact of the intervention was unaffected by clincians’ age, gender, or provider type.

LIMITATIONS:

  • This study only tested spaced education in reducing inappropriate prostate cancer screening; results may not be the same when SE is applied for other purposes.

IMPLICATIONS:

  • By facilitating the translation of CPGs into improved clinical care, spaced education interventions may offer a possible solution to the somewhat limited impact of CPGs on clinical practice.

AUTHOR/FUNDING INFORMATION:
This study was partly funded through HSR&D (TEL 02-100 and IIR 04-045). Dr. Kerfoot also was supported by an HSR&D Career Development Award.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
