<p><strong>BACKGROUND: </strong>The 2016 Presidential Commission to Eliminate Child Abuse and Neglect Fatalities identified systematic review of all cases of near-fatal child maltreatment as a necessary step towards prevention of child maltreatment fatalities. A critical barrier to adoption of this recommendation is the lack of a standard definition of "near-fatality" in the context of suspected child maltreatment.</p>

<p><strong>OBJECTIVE: </strong>To develop a consensus definition of near-fatal child maltreatment to be used in practice, policy, and research.</p>

<p><strong>PARTICIPANTS AND SETTING: </strong>A multidisciplinary expert panel of 23 individuals from across the U.S. including child abuse pediatricians, pediatric intensivists, pediatric emergency medicine physicians, child welfare administrators, child welfare researchers, and child injury/fatality researchers.</p>

<p><strong>METHODS: </strong>A modified Delphi process reflecting an iterative process of 3 rounds of surveys of expert opinion, statistical summary of survey response, and feedback of summary statistics. Consensus was defined as 75 % of panelists ranking an element as required (≥80 on a scale of 0-100) to meet a definition of near-fatality (75th% threshold).</p>

<p><strong>RESULTS: </strong>Experts defined near-fatal child maltreatment as life-threatening cardiopulmonary dysfunction directly attributable to suspected abuse or neglect as evidenced by (a) respiratory insufficiency/failure requiring intubation and mechanical ventilation, (b) respiratory insufficiency/failure requiring medications to reverse effects of toxic ingestion, or (c) cardiac arrhythmia with/without cardiopulmonary resuscitation (CPR).</p>

<p><strong>CONCLUSIONS: </strong>A consensus definition of near-fatal child maltreatment should be introduced in child protective services processes and in child fatality/near-fatality reviews to improve our ability to identify, review, and respond to trends in near-fatal child maltreatment at local, regional, and national levels.</p>
