Next of Kin-Interview Toolkit

A next-of-kin (NOK) interview provides an in-depth look at how someone lived, their social supports, and the circumstances that led to an overdose death. NOK interviews are tools overdose fatality reviews (OFRs) can use to expand their understanding of the life experiences of a decedent and identify non-traditional touchpoints or systems that may not be represented by OFR team members. This toolkit provides readers with information needed to identify, conduct, and report on a NOK interview.



  • Why to conduct a NOK Interview?
  • Who Should Conduct a NOK Interview?
  • When to Connect With NOK?
  • How to Conduct a NOK Interview?
  • Where to Store NOK Interview Data?
  • How to Use NOK Data?
  • Self-Care for NOK Interviewers

Toolkit Design

The Next-of-Kin Interviews: A Practitioner’s Guide to Implementation is a companion document to Overdose Fatality Review: A Practitioner’s Guide to Implementation. This guide provides readers with information needed to identify, conduct, and report on a NOK interview. The content draws on practice-based knowledge of conducting NOK interviews as part of the OFR. It is organized into seven modules and an appendix with a list of common phrases and definitions and resources.
