Patient navigators increased colon cancer screening in diverse, hard-to-reach populations. This evidence-based program also improved bowel preparation quality for males undergoing colonoscopy.

Area of Science:

  • Public Health
  • Gastroenterology
  • Health Services Research

Background:

  • Colon cancer screening rates remain suboptimal, particularly in diverse and hard-to-reach populations.
  • Low-quality bowel preparation can compromise colonoscopy effectiveness, leading to incomplete examinations or cancellations.
  • Patient navigation is a promising strategy to improve healthcare access and adherence to screening protocols.

Purpose of the Study:

  • To evaluate the effectiveness of a theory-driven, community-partnered patient navigator intervention.
  • To assess the intervention's impact on colon cancer screening knowledge, completion rates, and participant satisfaction.
  • To compare screening outcomes, including polyp detection and bowel preparation quality, between navigated and non-navigated patients.

  • A tailored intervention utilizing evidence-based practices and patient navigators integrated into gastroenterology clinics.
  • Enrollment of 415 ethnically diverse participants via inreach and community outreach over 16 months.
  • Facilitation of screening completions for 358 identified patients; comparison with a matched sample of 214 non-navigated patients.

Main Results:

  • Patient navigators successfully enrolled a diverse cohort and facilitated screening completion for 61% of eligible patients.
  • Participant satisfaction with the navigation program was high, reported by 89% of individuals.
  • Navigated males demonstrated significantly improved bowel preparation quality (OR = .418, p = .020) compared to non-navigated males; no differences in polyp detection were observed between groups.

Conclusions:

  • Evidence-based patient navigator programs are effective in increasing colon cancer screening uptake among underserved populations.
  • This intervention significantly enhances bowel preparation quality for male patients undergoing colonoscopy.
  • Patient navigation represents a valuable strategy for improving screening adherence and procedural quality in colon cancer prevention.
