Any provider working with victims of sexual assault where the offender is an intimate partner — often referred to as intimate partner sexual violence (IPSV) — should be trained in the use of lethality assessments or be familiar with the risk factors of IPSV. Individuals who are experiencing IPSV may be at risk of lethality, and appropriate awareness and training ensures more informed providers can identify and interrupt potentially lethal situations. Lethality assessments contributed to the rise in awareness and education about strangulation. SARTs can use evaluation or case review to identify opportunities to for education, prevention, or systems change.
Lethality risk assessment is important because — 
- it can reduce intimate partner homicide by giving responders a way to assess risk and intervene before there is a lethal assault,
- victims want to know more about their risk,
- victims may want evidence of dangerousness for civil and criminal proceedings,
- advocates and first responders want to be able to assess risk to provide victims with the safest responses possible,
- all disciplines need an accurate system to determine potential danger to victims, and
- factors exist that have been shown to distinguish between cases of intimate partner violence and those at risk of intimate partner homicide.
Further research on intimate partner homicide identified that —
- victims at risk of severe bodily harm or homicide worked infrequently with advocates, 
- victims had previously met with law enforcement in 50 percent of domestic violence homicides,  and
- it is possible to identify the risk of homicide by an intimate partner. 
The Lethality Assessment Program
It is important for SARTs to know how to use lethality assessment tools, such as the Lethality Assessment Program (LAP) that can help them identify high-risk cases. In 2003, the Maryland Network Against Domestic Violence (MNADV), noticing the identified gaps in services to victims who were murdered, developed the LAP for use by first responders.
The LAP includes a risk assessment screen to be used by first responders to identify and immediately connect individuals with the highest risk to advocacy. The LAP is also used to educate victims on risk factors of lethality as part of empowerment-based safety planning. Connecting victims to advocates enhances safety and improves the possibility victims will seek other services such as shelter, law enforcement, and medical services. After implementing the LAP, Maryland experienced a 34 percent drop in intimate partner homicides between July 2007 and June 2012. 
Over time, additional risk assessment programs were developed, and research continues to review and comment on their effectiveness. The lethality assessment screening tool is currently used as a component of the LAP in 32 states, with continued success.
A SART’s jurisdiction may use a lethality risk assessment instrument as part of domestic violence protocol or other coordinated community responses. SARTs should be aware of and familiar with any lethality risk assessment instruments being used in their jurisdiction. As those who commit domestic violence also commit sexual assault, victims may seek supportive services to address a sexual assault. Victims at risk may present to many of the disciplines represented on the SART. If the entire team knows how to assess lethality risks, more victims can be connected to advocacy services, which have been shown to reduce the risk of serious injury or homicide.
