AbstractBackground: Colorectal cancer (CRC) screening is underused by minority populations, and patient navigation increases adherence with screening colonoscopy. In this study, the authors estimated the cost-effectiveness of navigation for screening colonoscopy from the perspective of a payer seeking to improve population health.
Methods: A validated model of CRC screening was informed with inputs from navigation studies in New York City (population: 43% African American, 49% Hispanic, 4% white, 4% other; base-case screening: 40% without navigation, 65% with navigation; navigation costs: $29 per colonoscopy completer, $21 per noncompleter, $3 per non-navigated individual). Two analyses compared: 1) navigation versus no navigation for 1-time screening colonoscopy in unscreened individuals aged ≥ 50 years; and 2) programs of colonoscopy with versus without navigation versus fecal occult blood testing (FOBT) or fecal immunochemical testing (FIT) for individuals ages 50 to 80 years.
Results: In the base case: 1) 1-time navigation gained quality-adjusted life-years (QALYs) and decreased costs; 2) longitudinal navigation cost $9800 per QALY gained versus no navigation, and, assuming comparable uptake rates, it cost $118,700 per QALY gained versus FOBT but was less effective and more costly than FIT. The results were most dependent on screening participation rates and navigation costs: 1) assuming a 5% increase in screening uptake with navigation, and a navigation cost of $150 per completer, 1-time navigation cost $26,400 per QALY gained; and 2) longitudinal navigation with 75% colonoscopy uptake cost <$25,000 per QALY gained versus FIT when FIT uptake was <50%. Probabilistic sensitivity analyses did not alter the conclusions.
Conclusions: Navigation for screening colonoscopy appears to be cost-effective, and 1-time navigation may be cost-saving. In emerging health care models that reward outcomes, payers should consider covering the costs of navigation for screening colonoscopy.
