Introduction   

In the United States, an estimated 48,000 to 98,000 hospitalized patients lose their lives per year due to medical errors, including cases of preventable cardiopulmonary arrest [1]. In the hospital setting patients can show signs of physiological decline several hours before experiencing cardiac arrest [11]. 

Studies indicate that up to 50% of severe adverse events including in house cardiac arrest (IHCA) and unplanned admissions to intensive care units, and death are avoidable [2]. Between 50-57% of in-hospital cardiac arrests (IHCA) take place on hospital units, where the survival outlook is poor, with about 83% of patients dying within 30 days [2]. In comparison, when in hospital cardiac arrests (IHCA) occur in a cardiac catheterization setting, the 30-day mortality rate drops to 37% [2]. 

The Rapid Response System (RRS) stands as a vital safeguard within healthcare environments, enabling staff across all levels to request immediate, specialized support when a patient exhibits signs indicative of acute health decline [11]. The introduction of Rapid Response Teams (RRTs) was a key strategy toward enhancing healthcare outcomes, highlighted by the “Saving 100,000 Lives” campaign, leading to the adoption of RRTs by hospitals across the globe.  

Initiated in 2004 by the Institute for Healthcare Improvement (IHI), the “Saving 100,000 Lives” campaign advocated for the adoption of Rapid Response Teams (RRTs) as a method to enhance healthcare quality [3]. Composed of multidisciplinary professionals, RRTs should identify and manage patients at elevated risk and improve the “chain of prevention,” lowering instances of cardiac arrests and in-hospital deaths [4].  

Despite their intuitive appeal and widespread adoption, the evidence on their efficacy is varied, highlighting the necessity for an in-depth exploration of the elements influencing their success and areas for improvement [5]. The endorsement of RRTs is vital for the successful deployment and influenced by the perception of the teams’ benefits, which plays a significant role in the systems’ ongoing use and sustainability [6][13].  

Participants will gain comprehensive insights into the complex impacts of RRTs on patient safety and the metrics of hospital quality. Understanding the viewpoints of various stakeholders, including nurse leaders, RRT members, and the broader healthcare team, will enable participants to champion practices that boost the efficacy and sustainability of RRTs, leading to enhanced patient care and results.  

The focus will be on the integral function of Rapid Response Teams (RRTs) and Medical Emergency Teams (METs) in preventing in-hospital cardiac arrests (IHCAs), improving patient outcomes, and elevating the overall quality of care.  

Composition of Rapid Response Teams 

Rapid Response Systems (RRSs) have four fundamental components, ensuring a comprehensive approach to patient care: case detection, medical response, administrative oversight, and quality improvement [7][8]. 

Case Detection 

The afferent limb (case detection and response triggering) is the first critical component, comprising trained healthcare providers including nurses and respiratory therapists who can identify early signs of patient deterioration and initiate the activation of the Rapid Response Team (RRT) [7][8].  

This component is vital for bridging the gap between patients at risk and the response team. In addition, healthcare facilities can empower family members to trigger the RRT, acknowledging the valuable role they can play in patient care [9]. 

Medical Response 

The efferent limb (medical response) represents the core of the RRS [7][8]. Critical care nurses, physicians, including hospitalists, intensivists, or emergency doctors can lead teams [10][11]. Key capabilities for the team include prescribing medications, performing advanced airway management, establishing central venous access, and delivering ICU-level care at the patient’s bedside [12].  

In addition to clinical interventions, the team also plays a crucial role in transferring patients to the ICU as needed and educating unit staff [12][13]. The success of the RRT hinges on effective collaboration and a supportive relationship with the afferent limb, highlighted by staff readiness to assist and activate [14].  

Administrative Oversight 

An administrative arm oversees the RRT, ensuring the team functions by facilitating access to necessary resources and administrative support and essentials for the team’s success and sustainability within the hospital environment [15][16][26]. 

Quality Improvement 

The quality improvement arm focuses on the continual evaluation of the RRT’s interventions [17]. By reviewing activations and providing feedback on team performance, this component plays a key role in enhancing the quality of care [18][19]. Quality improvement tracks quality indicators, including staff satisfaction, the frequency of cardiac arrests outside the ICU, ICU admissions, and the annual rate of hospital deaths per 1,000 discharges, enabling ongoing improvements to the system [18]. This multifaceted structure ensures that RRTs can provide efficient care to patients showing signs of acute deterioration, aiming to improve patient outcomes [18]. 

Bedside nurses play a crucial role in the continuous monitoring and evaluation of hospital patients, where achieving optimal patient outcomes rely on the identification of minor changes in patient conditions and the immediate actions of these nurses [20][21]. The effectiveness of this approach centers on the bedside nurse’s vigilance and sharp assessment skills, coupled with their ability to collaborate and communicate with more experienced healthcare colleagues [24].  

Recognizing early signs of patient distress and initiating appropriate action necessitates a delicate balance between managing complex healthcare needs and leveraging the nurse’s expertise and capabilities [20][21]. Prompt detection and rapid deployment of resources are essential for reducing mortality outside the intensive care unit (ICU), yet the main challenge lies in the bedside nurse’s ability to spot early signs of patient decline and activate the necessary response team [3][22].  

Theoretical Framework 

Discrepancies in patient care often point to a misalignment between patient needs and nurse competencies [23]. These factors may leave nurses ill-equipped to meet the growing demands of patient care, encompassing physical, psychological, and spiritual needs. The American Association of Critical Care Nurses (AACN) Synergy Model for Patient Care promotes matching patient needs with nurse competencies to optimize care outcomes [25].  

Barriers to Nurse Activation 

Three main factors influence the activation of Rapid Response Teams (RRTs): (1) the hospital’s structure and available resources, (2) the prevailing attitudes and practices among healthcare professionals, and (3) the beliefs, characteristics, and understanding of the nurses [26][27].  

The RRT framework emphasizes identifying obstacles that nurses encounter in activating RRTs upon observing patient deterioration. The quality of clinical relationships and team dynamics influence the effectiveness of RRTs, which can either prompt or hinder a nurse’s response to patient needs [26]. 

Clinical Judgment Factors 

Hesitation and uncertainty in nursing can postpone essential interventions resulting in negative outcomes for patients [3]. The primary safeguard against a patient’s rapid deterioration is the bedside nurse’s ability to recognize and act upon physiological changes [20][21].  

Nevertheless, novice nurses may feel apprehensive about making these evaluations, which can delay critical care interventions [28][29]. By focusing on specialized training in Rapid Response Team (RRT) protocols and incorporating early warning systems, it is possible to reduce this hesitancy and improve patient care [28]. 

The relationship dynamics among bedside nurses, their peers, and physicians can discourage nurses from activating the Rapid Response Team (RRT), impacting their self-assurance and perceived competence [3].  

If nurses encounter indifference or skepticism from RRT members it can undermine trust and confidence within the healthcare team, thereby impeding prompt and effective responses to patient requirements [12] [30]. 

Organizational Culture 

Fostering a supportive organizational culture is essential in equipping bedside nurses with the necessary knowledge and skills to identify and respond to signs of patient decline [3]. This requires offering access to educational resources and competency-based training, essential for improving patient outcomes [31].  

The organizational environment should encourage a focus on safety, standardizing procedures, and creating early warning mechanisms to steer nursing practices toward better patient care [15]. 

Role of Rapid Response Teams  

Rapid Response Teams (RRTs) are for the rapid deployment of experienced healthcare professionals to the bedside of patients showing signs of critical illness, with the goal of conducting immediate assessments, triage, and interventions to halt further health decline [3][4].  

Patients experiencing delayed activation of the Rapid Response Team (RRT) succumbed to their conditions in the hospital and had longer hospital stays compared to those who had prompt activation of a RRT [12]. The implementation of the focused RRT models correlated with a significant decline in the rate of cardiac arrests per 1,000 admissions across the units [12]. An essential aspect of RRTs is their ability to extend critical care expertise to patients outside of the ICU [32]. 

The most consistent outcome observed in assessing the effectiveness of Rapid Response Teams (RRTs) is the decrease in in-hospital cardiac arrests through detection of and intervention for patients at risk [5].  

Activation Criteria  

The selection of activation criteria is critical and encompasses a wide range of clinical signals that denote an impending patient crisis. These criteria should enable precise and early patient identification while minimizing false alarms [33]. Early Warning Scores (EWS), result from routine vital sign measurements, have shown superior predictive ability for adverse clinical outcomes compared to single vital sign abnormalities and their adoption can reduce cardiac arrest rates and mortality [34].  

These activation guidelines include physiological measures such as a heart rate outside the 40 to 140 beats per minute range, respiratory rates beyond the 8 to 28 breaths per minute bracket, systolic blood pressure readings outside 90 to 180 mmHg, and oxygen saturation levels below 90% despite supplemental oxygen [11].  

Other critical indicators for RRTs engagement include significant alterations in a patient’s mental state, urine output dropping to less than 50 cc over four hours, or when a staff member has a grave concern for a patient’s immediate well-being [11]. Some institutions have augmented these standards with additional criteria to address specific urgent situations, such as persistent chest pain not alleviated by nitroglycerin, compromised airways, ongoing seizure activity, or unmanaged pain [11][35]. Incorporating a subjective criterion, such as significant concern for a patient’s condition, acknowledges the value of clinical experience and intuition [11][20][21].  

The initiation of the RRT should prompt a response within 15 minutes and occur via overhead announcement or dedicated communication devices [35]. Effective communication utilizes the SBAR (Situation, Background, Assessment, Recommendation) technique, and access to medical records and recent lab results are critical for an efficient and informed RRT response [36].  

Definitions 

Rapid Response Systems (RRS): Programs aimed at enhancing the safety of hospitalized patients experiencing rapid health deterioration [11]. These systems rely on the early identification of high-risk patients, and the prompt notification of a response team including the swift intervention, and continuous performance assessment. 

Critical Care Outreach Teams (CCOT): A variation of RRS that responds to emergencies but also focuses on educating non-critical care staff about critical care practices and facilitates smoother transitions between Intensive Care Units (ICUs) and general hospital wards [37]. 

Medical Emergency Teams (MET): These are physician-led teams equipped with the skills to manage complex medical situations, such as managing difficult airways, establishing central venous access, and providing ICU-level care at the patient’s bedside [38]. 

Medical Response Teams: A broader term that can encompass several types of teams responding to medical emergencies within a hospital setting, without specifying the team’s composition or leadership [38]. 

Rapid Response Teams (RRT): Nurse-led teams activated to address acute changes in a patient’s condition, ensuring immediate care to prevent further deterioration [3][11]. 

Case Study  

John Doe, a 65-year-old male with a history of hypertension and diabetes is admitted to a hospital for elective hip replacement surgery. On the second post-operative day, nursing staff noted subtle changes in John’s vital signs, including an increase in heart rate (tachycardia), respiratory rate (tachypnea), and a decrease in oxygen saturation (hypoxia), despite supplemental oxygen. 

The Tipping Point 

At 0200 hours, the nurse observed that John’s respiratory rate had increased to 31 breaths per minute, and his oxygen saturation had dropped to 85% with a complaint of chest pain. Understanding the hospital’s RRT activation criteria, the nurse activates the Rapid Response Team. 

During the rapid response, the bedside nurse delivers a concise SBAR (Situation, Background, Assessment, Recommendation) report to ensure efficient and effective communication with the team [36]. 

• Situation: John Doe, admitted for elective hip replacement surgery, is experiencing a sudden increase in his respiratory rate of 31 breaths per minute with chest pain, shortness of breath, an oxygen saturation of 85%  

• Background: John is a 72-year-old post op hip with a history of hypertension and diabetes.  

• Assessment: Over the past half-hour, Johns respiratory condition has changed without improvements from standard interventions including inhalers, supplemental oxygen, and breathing treatments.  

• Recommendation: Primary nurse activated the Rapid Response Team to evaluate and manage the situation. 

Initial Bedside Management 

Initial bedside management of the RRT includes: 

• Prompt addressing and management of chest pain  

• Vital signs to assess the patient’s status 

• Supplemental oxygen to maintain adequate oxygen levels 

• Electrocardiogram (ECG) to assess heart function 

• Aspirin and nitroglycerin to mitigate chest pain 

• Elevate the head of bed 45 degrees to ease breathing 

• Continuous monitoring to observe cardiac activity 

• Laboratory tests to measure troponin levels (cardiac enzymes) 

• Transfer to a higher level of care 

RRT Intervention 

The RRT, comprising a critical care nurse, a respiratory therapist, and an intensivist, responded. The team administered aspirin, high-flow oxygen, and ordered chest X-rays and blood tests including a VBG (venous blood gas) and d-dimer, suspecting a possible pulmonary embolism.  

Outcome 

The rapid intervention by the RRT led to an early diagnosis of a pulmonary embolism, anticoagulation therapy, and transfer to the ICU for further management. Because of the early detection and response by the bedside nurse, John’s condition stabilized, and he made a full recovery. John’s case highlights the critical role of RRTs in improving patient safety and outcomes and underscores the importance of vigilance, prompt action, and the seamless collaboration between hospital staff and specialized teams in mitigating risks and enhancing patient care quality. 

• How did the nurse’s vigilance and prompt activation of the Rapid Response Team (RRT) contribute to the early identification of and intervention for John Doe’s post-operative complications? 

• What does this scenario illustrate about the importance of nursing staff in recognizing early signs of patient deterioration? 

• What does this scenario suggest about the potential impact of continuous education, clear communication, and the engagement of all healthcare providers on the quality of patient care and safety initiatives within healthcare settings? 

Conclusion

Evidence suggests that many severe adverse events, such as in-hospital cardiac arrests (IHCAs), unplanned ICU admissions, and deaths, are avoidable, with a considerable proportion of IHCAs occurring in general hospital units where survival rates are poor [2][3]. To combat this, the Rapid Response System (RRS) and Rapid Response Teams (RRTs) have evolved as key interventions to improve patient safety by providing immediate specialized support for patients showing signs of acute decline [2][9][11].  

These systems are part of a broader effort to reduce IHCAs and improve overall healthcare quality, highlighted by initiatives like the “Saving 100,000 Lives” campaign [3]. 

The composition of RRTs includes four essential components: case detection, medical response, administrative oversight, and quality improvement, emphasizing continuous monitoring and intervention for patients at risk [7][8][9].  

Despite their promise, barriers exist, including hospital structure, professional attitudes, and nurse readiness, which can impede RRT activation [26][27]. In addition, clinical relationships, organizational culture, and the selection of appropriate activation criteria play significant roles in the system’s success [3][15][31]. This comprehensive approach underscores the necessity of continuous education, clear communication, and engagement in safety initiatives to enhance patient care quality and reduce preventable adverse events.
