This study assesses if patient navigation has unintended benefits for the populations in which patients are embedded and to estimate its cost-effectiveness when including such benefits. The study examines:

  1. If navigation led patients to share information more often and to more individuals than standard care among 100 African American breast cancer patients from a completed trial.
  2. How navigation thus resulted in greater breast cancer care use among 150 screening-eligible women within patients' networks
  3. If cost effectiveness of navigation is greater, when accounting for the indirect effects on women in participants' networks in addition to its direct effects on participants.
Researchers are modeling how navigation may lead to population-level improvement in stage at diagnosis through 3 network mechanisms (i.e., navigation results in increased, sustained communication; larger networks; more pivotal network positions for navigated women) and how effects vary depending on distribution of networks' breast cancer risk.
