A rapid response system (RRS) is a system implemented in many hospitals to identify and respond to patients with early signs of clinical deterioration. The goal of a rapid response is to intervene before the onset of injury, respiratory arrest, or cardiac arrest. Rapid response teams (RRTs) were first described in the 1990s and have been commonplace in US hospitals since the late 2000s. They are generally not the primary service and are dependent on the willingness of front-line providers and nurses to be activated. The overall effectiveness of rapid response teams is somewhat controversial due to the variability across studies.

Rapid response teams (RRTs) are a key intervention in the 100,000 Lives Campaign
Rapid response teams (RRTs) are groups of medical experts who respond to patients experiencing unexpected medical emergencies. They are a key component of a hospital's rapid response system (RRS), which aims to reduce failure-to-rescue events and meet the needs of patients facing unforeseen medical crises. RRTs are trained in early resuscitation interventions and advanced life support, rushing to the patient's bedside to prevent respiratory and cardiac arrest and improve patient outcomes.
RRTs were introduced in 2004 as part of the Institute for Healthcare Improvement's (IHI) "100,000 Lives Campaign," which aimed to improve patient safety and decrease mortality in six clinical areas. The campaign, announced by IHI President and CEO Dr Berwick, garnered attention from nearly half of the hospitals in the United States within a year. The inclusion of RRTs in this campaign brought them to the forefront as a vital patient safety intervention.
The concept of RRTs is simple yet powerful: when a patient shows signs of imminent clinical deterioration, a multidisciplinary team is summoned to immediately assess and treat the patient, with the goal of preventing ICU transfer, cardiac arrest, or death. RRTs are activated through the afferent component of the RRS, which identifies early warning signs, and they constitute the efferent component, providing a rapid response.
The effectiveness of RRTs in reducing ICU transfers is inconclusive, with some studies showing a decrease and others an increase. However, RRTs are associated with improved quality of care for patients experiencing unexpected medical emergencies. They are particularly effective in reducing respiratory and cardiac arrests outside the intensive care unit and decreasing the chance of in-hospital death. RRTs are also valuable in detecting underlying patient safety issues within hospitals.
Sustaining RRTs is crucial to achieving long-term benefits for patients, staff, and hospitals. Nurse leaders play a pivotal role in implementation efforts, providing staffing, developing policies and procedures, and offering RRT training to frontline staff. However, the factors required for RRT sustainability remain unclear, and the overall effectiveness of RRTs in improving patient safety is still debated due to variability across studies.

RRTs are commonplace in US hospitals and consist of nurses, providers, and respiratory therapists
Rapid response teams (RRTs) are a commonplace intervention in US hospitals. They consist of nurses, providers, and respiratory therapists, all of whom have impeccable clinical skills. RRTs are summoned when a patient shows signs of imminent clinical deterioration, such as abnormal vital signs, with the goal of preventing intensive care unit transfer, cardiac arrest, or death.
The concept of RRTs was first introduced in the 1990s, but they became commonplace in the late 2000s, after the Institute for Healthcare Improvement included them in their "100,000 Lives Campaign". This campaign, along with the Joint Commission's National Patient Safety Goal to improve "recognition and response to changes in a patient's condition", spurred the widespread adoption of RRTs in US hospitals.
RRTs are designed to provide on-the-fly critical care in respiratory, cardiac, neurologic, and other clinical emergencies. They are often the difference between life and death for patients whose conditions deteriorate acutely while hospitalized. The team is multidisciplinary, with members trained in early resuscitation interventions and advanced life support. They rush to the patient's bedside to prevent respiratory and cardiac arrest and improve patient outcomes.
The effectiveness of an RRT depends on the willingness of the primary service to seek their help. As such, RRT members must not only be skilled clinicians but also effective communicators and collaborators. They need to build trust with nursing staff, providers, and other hospital personnel to ensure they are activated when needed. RRTs also rely on the timely identification of warning signs, which can be facilitated by track-and-trigger bedside monitoring systems that automatically trigger intervention when certain abnormalities are detected.

RRTs provide on-the-fly critical care in respiratory, cardiac, and neurological emergencies
A rapid response system (RRS) is a system implemented in many hospitals to identify and respond to patients with early signs of clinical deterioration. The goal is to prevent respiratory or cardiac arrest and intensive care unit transfer, cardiac arrest, or death. RRSs consist of two clinical components: an afferent component and an efferent component, as well as two organisational components: process improvement and administrative. The afferent component involves identifying early warning signs that trigger a response from the efferent component, which is the rapid response team (RRT).
RRTs are composed of nurses, providers, and/or respiratory therapists with strong clinical skills. They function as a "clinical Swiss Army Knife", providing critical care outside the intensive care unit (ICU) and handling respiratory, cardiac, neurological, and other clinical emergencies on the fly. RRTs require activation from the front lines and their success in improving patient outcomes is correlated with the number of activations. It is important to encourage formal RRT activation and proactively assess patients at risk of deterioration.
In addition to their clinical skills, RRTs also require strong political skills. They should show gratitude for every call and not undermine the primary service, even if they have more knowledge about the clinical process. RRTs should build trust with nursing staff and providers outside of an RRT response, regularly share their successes, and not overstaff activations, sending only the essential personnel.
Specialised subsets of RRTs have been developed, including sepsis teams, pulmonary embolism response teams, and oncology-specific RRTs, which face unique challenges related to underlying malignancies, treatments, and comorbidities. RRTs can also initiate specific pathways for different scenarios, such as emergency intubation, acute spinal cord catastrophe, or neurovascular interventions.

RRTs are activated when certain prespecified criteria are met, such as abnormal vital signs
Rapid response teams (RRTs) are a crucial aspect of hospital care, providing timely interventions for patients exhibiting signs of clinical deterioration. The activation of these teams is based on specific criteria, including abnormal vital signs, which indicate a potential decline in the patient's condition. This proactive approach aims to prevent adverse outcomes such as cardiac or respiratory arrest and even death.
The concept of RRTs was introduced in the 1990s, but they gained prominence in the late 2000s when the Institute for Healthcare Improvement included them in the "100,000 Lives Campaign." Since then, RRTs have become commonplace in hospitals, particularly in the United States. The team composition varies but typically includes nurses, providers, and respiratory therapists—skilled professionals equipped to handle a range of clinical emergencies.
The activation of an RRT is triggered by pre-specified criteria, which can include abnormal vital signs such as a high respiratory rate, oxygen saturation below 90% These criteria are standardised tools that help identify early signs of reversible clinical deterioration. By using these tools, bedside staff, or even patients and their families in some hospitals, can promptly activate the RRT when they observe concerning changes in the patient's condition.
The effectiveness of RRTs is closely linked to the number of activations, emphasising the importance of recognising the need for their intervention. This recognition is often facilitated by the afferent component of the rapid response system, which identifies the input early warning signs, triggering a response from the efferent component, the RRT. The afferent tools can include single-parameter calling criteria, where only one criterion is required to activate the RRT, or multi-parameter early warning scores that combine several parameters into a single early warning score.
The activation of RRTs based on abnormal vital signs and other prespecified criteria is a proactive approach to patient care. By responding to early warning signs, RRTs can intervene before a patient's condition deteriorates further, potentially preventing transfers to the intensive care unit and improving overall patient outcomes. This timely intervention not only benefits the patient but also contributes to the detection of underlying patient safety issues within hospitals.

RRTs slightly reduce unexpected cardiac arrests but do not affect overall in-hospital mortality
A rapid response system (RRS) is a system implemented in many hospitals to identify and respond to patients with early signs of clinical deterioration on non-intensive care units. The goal is to prevent respiratory or cardiac arrest. Rapid response teams (RRTs) are summoned to the patient's bedside to immediately assess and treat the patient, with the aim of preventing intensive care unit (ICU) transfers, cardiac arrest, or death.
RRTs are composed of medical professionals trained in early resuscitation interventions and advanced life support. A typical team includes a doctor, a senior intensive care nurse, and a staff nurse. They are equipped with resuscitation drugs, fluids, and equipment. The activation of an RRT is triggered by the detection of deterioration through the patient's state, such as an altered heart rate, respiratory rate, blood pressure, or consciousness level.
While RRTs have been widely adopted by hospitals, their overall effectiveness in improving patient outcomes is still debated. Some studies have shown that RRTs can reduce the incidence of unexpected cardiac arrests, but their impact on overall in-hospital mortality remains inconsistent. For example, a study in a 300-bed private hospital found that the incidence of unexpected cardiac arrest decreased from 17 per 1000 admissions before RRT intervention to 12.45 per 1000 admissions after the intervention. However, the mortality rate remained relatively unchanged, with a slight decrease from 73.23% to 66.15%.
The reasons for the inconsistent effects of RRTs are complex and may be influenced by local practices and cultural factors that impact the utilization of these teams. While RRTs are popular among nursing staff and can help identify patient safety issues, the lack of standardized approaches to establishing and managing RRTs may contribute to the variability in outcomes.
In conclusion, while RRTs have shown a slight reduction in unexpected cardiac arrests, they do not appear to significantly impact overall in-hospital mortality. Further research and standardized approaches are needed to enhance the effectiveness of RRTs and improve patient outcomes.

Frequently asked questions
A rapid response in a hospital, also known as a rapid response system (RRS) or rapid response team (RRT), is a system implemented in many hospitals to identify and respond to patients with early signs of clinical deterioration. The goal of a rapid response is to intervene before the onset of injury, respiratory arrest, or cardiac arrest.
A rapid response can be initiated by anyone, including family, hospital staff, nursing staff, physicians, and visitors. At certain hospitals, patients and family members are also permitted to call the team.
A rapid response and a code blue are similar in that they alert a team of highly trained clinicians to respond to a medical emergency. However, a rapid response is for the prevention of serious injury, cardiac arrest, and respiratory arrest, while a code blue is called for a person who has already stopped breathing or whose heart has stopped beating.
A rapid response system consists of two clinical components: an afferent component and an efferent component. The afferent component, also known as the identification limb, uses standardized tools to track early signs of reversible clinical deterioration and trigger a call to the efferent component. The efferent component, or response limb, is the rapid response team that rushes to the patient's bedside to provide treatment.
