The abstract discusses a very important topic of trauma-informed care principles and strategies. The setting is an Emergency Department. There is discussion on how the article will discuss the main pillars of Trauma-Informed Care and how they relate to patients that are being seen for traumatic injuries. The abstract states that the authors will be providing practice considerations for ER MDs in their clinical delivery of these specific populations. As the article is written by MDs, it is appropriate that the focus is for MDs. The title is clear in that it states the main idea (TIC), the setting (ER) and the population (Traumatic injury).

The literature review discusses the origin of Trauma-Informed Care and that research is still in the early stages of the concept and emergency rooms. The article is a review of the main guiding principles according to SAMHSA and how ER MDs can incorporate these strategies into their own practices. As the topic is a relatively new topic in the arena of Emergency Medicine, the literature review is a good start in determining what has been researched to date on Trauma-Informed Care.

The results of the literature review are separated into the following categories: Widespread Scope of Trauma Recognizing the S/S of Trauma--Chart of S/S trauma, Chart of Helpful Phrases during debriefing, Chart of 10 domains of De-escalation *Clinical Care in Trauma--chart of psychological first aid in ER, chart of a trauma-informed care system

The data is presented in 3 major components. The tables and relevant and clearly presented. The categories of review start at an overview, then specifics on trauma, and finally how to move into the ER unit. The final category is specific to the purpose of the article and its "title".

Major points in the article which needs clarification, refinement, reanalysis, rewrites and/or additional information and suggestions for what could be done to improve the article.

1. There are 81 references provided. Some of the references are not complete in regards to citation. The majority of the references are not current (Within 5 years of article-Feb 2019).
2. The authors do not specify what type of literature review they are completing, nor do they discuss the search methods that were utilized in gathering the sources. There is not any discussion on what variables the authors included/excluded in their search of the literature. The study method is not complete in that it does not have the potential to be replicated.
3. The article does not discuss any limitations for the study. The conclusions do give an overview of the results--however, it still appears very broadly discussed.
4. There is not a discussion on opportunities for future research.

Minor points like figures/tables not being mentioned in the text, a missing reference, typos, and other inconsistencies.

1. One item that would be helpful--is perhaps a chart on the last category in how MDs can incorporate Trauma-Informed Care in their practice.
