Description of original award (Fiscal Year 2004, $104,071)
The investigators plan to demonstrate (1) the proportion of suspects who sustain injuries after less-lethal weapons(LLWs) have been used during their apprehension by law enforcement officers, and (2) the severity pattern of those injuries.  A prospective multi-center trial will involve up to 12 qualifying law-enforcement agencies across the nation that use less lethal kinetic impact munitions and electrical incapacitation devices. A tactical physician already affiliated with the law enforcement agency will review each case. The physician will identify and classify any injuries sustained due to LLW use, complete a case report form and submit the form to a central study site. The unique status of tactical physicians, who bring medical expertise and act within the loop of confidentiality for both law enforcement and medical care, will facilitate this study. The central study site database will be analyzed to determine the percentage of suspects who suffer injuries after less lethal weapon deployment, and the severity of those injuries. This will be the first study of its kind, featuring physician level review of 100 percent of LLW uses in the participating agencies.

Supplemental Award 1 (Fiscal Year 2006, $29,059)
This prospective multicenter trial involves 12 law-enforcement agencies across the nation that utilize less lethal kinetic impact munitions and electrical incapacitation devices.  Currently 9 agencies are collecting data with the remaining three in the approval stage.  This study will utilize a tactical physician affiliated with the law enforcement agency to review each case, which may include medical records retrieved by the agency as part of its use of force investigation and reporting process.  The site investigator / physician identifies and classifies any injuries sustained due to LLW use, completes the case report form and submits the form to the central study site.  The central study site database will be analyzed to determine the percentage of suspects who suffer injuries after less lethal weapon deployment, and the severity of those injuries.

    Supplemental Award 2 (Fiscal Year 2007, $237,523)
The continuation of the LLW Study will provide for an additional year of data collection using the ongoing study design. This will expand the project to an anticipated number of well over 1000 real-world uses of conducted energy weapons (CEW) and kinetic impact projectiles. The size and strength of this database is unprecedented and should allow for multiple subset analyses after the planned primary analysis describing the injury epidemiology associated with each weapon class.  Also, a pilot study will be conducted that will demonstrate metabolic and electrocardiographic changes over time in a group of subjects who have been exposed to a CEW during their apprehension and arrest. These suspects will be admitted to the hospital for observation and serial laboratory testing. In an IRB-reviewed study the subjects' clinical and laboratory data will be collected and compared to similar subjects that were not exposed to a CEW. This is the first time such data has been captured among real-world suspects and is expected to produce new information regarding the effects of illicit drugs, fleeing and physical struggling with police, conducted energy weapons, physical fitness and medical conditions, and other factors that cannot be replicated in laboratory or volunteer settings.
