Development of Interview Guide

• Study investigators worked together to determine
  aspects of the research question that would best
  be collected through patient narratives
• Committees of Aboriginal community members and TB
  stakeholders provided feedback advised upon
  historical perspectives establishing
  relationships, which was then integrated into the
  interview tool
• Study coordinators worked with qualitative
  investigators to integrate patient responses into
  final interview guide

Analysis Framework

• A standardized set of interview codes were
  inductively developed and refined utilizing
  cross-province data
• Based on the codes, a framework was inductively
  developed in which to categorize interview data
• Information was continually vetted through
  Committees and analysis was refined accordingly
