Identification of persons based on verbal descriptions is one of the key skills of police work. Gathering as much description information as possible immediately following the event—for example, at the point of emergency police dispatch—could substantially improve the accuracy of suspect descriptions, the ability to locate missing persons quickly, and other key outcomes of effective police work. The primary objective of this study was to determine what amount and type of persons description information is collected by...

Multi-Protocol Discipline Agencies Use Different Protocols To Process Traffic Accidents

Chris Knight, Christopher Olola, PhD, Greg Scott, MBA, EMD-QI, Isabel Gardett, PhD, Jeff J. Clawson, MD

Apr 03, 2018|AEDR 2018 Vol. 6 Issue 1|Original Research

Traffic incidents (collisions and crashes) are among the most common call types handled by Emergency Communication Centers (ECCs). They are also among the most complex call types because they represent such a range of possible situations. ECCs that handle calls in multiple disciplines (medical, fire, and law enforcement) may have multiple protocols available for handling traffic incidents because the Medical Priority Dispatch System, Police Priority Dispatch System, and Fire Priority Dispatch System each contains its own traffic and transportation incident protocol...

Weapons Reported On-Scene by Callers to Emergency Police Dispatch

Meghan Broadbent, MS, Chris Knight, David Warner, Nathan Williams, BS, Greg Scott, MBA, EMD-QI, Jeff J. Clawson, MD, Isabel Gardett, PhD, Christopher Olola, PhD

Apr 03, 2018|AEDR 2018 Vol. 6 Issue 1|Original Research

Providing information about possible weapons on scene is an essential objective of police dispatching and clearly valuable to officer safety. However, up to now, no information has been available about how often callers report weapons as "involved or mentioned" in an incident, what types of weapons are most commonly reported, or which incident types most commonly have reported weapons associated with them. The primary objective of this study is to determine which types of weapons are reported most often and on which Police Priority Dispatch System (PPDS®)...

Characterization of Call Prioritization Time in a Police Priority Dispatch System™

David Warner, Shawn Messinger, Chris Knight, Greg Scott, MBA, EMD-QI, Jeff J. Clawson, MD, Isabel Gardett, PhD, Tracey Barron, BS, Mark Rector, Brett Patterson, Lazaro Guerra, Angela VanDyke, Christopher Olola, PhD

Time-to-dispatch in a 911 center continues to be a topic of much discussion in public safety. This study represents a first attempt to classify a subset of time-todispatch, call prioritization time, the time required to gather critical information prior to dispatching the call. The study characterizes call prioritization time in two Police dispatching agencies by determining overall median call prioritization time for all Chief Complaints (CCs) in the agencies studied, then by determining specific call prioritization times for the top five most commonly-used CCs...

Research and the Realities of Police Dispatch

Chris Knight

Aug 13, 2013|AEDR 2013 Vol. 1 Issue 2|Perspectives

The reality of police dispatching is that there is nothing routine. Police calls change frequently simply due to the type of business. A perceived cold call of "breaking and entering" into a property can quickly turn into an in-progress "robbery" when it is discovered that a suspect is on the scene and has a weapon. A report of an "assault" can quickly turn into an "active assailant (shooter)" situation, one of the most dangerous and complex types of incidents. The constantly-changing police world is just never routine. Because of the constantly-changing nature of policing and police...

The Distribution Of Emergency Police Dispatch Call Incident Types and Priority Levels Within the Police Priority Dispatch System

Shawn Messinger, David Warner, Chris Knight, Greg Scott, MBA, EMD-QI, Mark Rector, Tracey Barron, BS, Angela VanDyke, Lazaro Guerra, Isabel Gardett, PhD, Brett Patterson, Jeff J. Clawson, MD, Christopher Olola, PhD

Aug 03, 2013|AEDR 2013 Vol. 1 Issue 2|Original Research

911 centers receive a wide variety of calls for police-related incidents. Using the Police Priority Dispatch System (PPDS®), a 911 Emergency Police Dispatcher (EPD) categorizes each incident with a specific Chief Complaint (CC) and prioritizes the case using a systematic alpha-numeric coding matrix. The wide variation in CC types and specific codes assigned can profoundly affect staffing and resource deployment decisions made by law enforcement agencies. However, the frequency of specific call types and priority levels in the PPDS has not been studied formally to date. The objective of...
