Objective The objective of this study was to qualitatively describe the impact of a Rapid Response Team (RRT) at a 944-bed, university-affiliated hospital.
Methods We analysed 49 open-ended interviews with administrators, primary team attending physicians, trainees, RRT attending hospitalists, staff nurses, nurses and respiratory technicians.
Results Themes elicited were categorised into the domains of (1) morale and teamwork, (2) education, (3) workload, (4) patient care, and (5) hospital administration. Positive implications beyond improved care for acutely ill patients were: increased morale and empowerment among nurses, real-time redistribution of workload for nurses (reducing neglect of non-acutely ill patients during emergencies), and immediate access to expert help. Negative implications were: increased tensions between nurses and physician teams, a burden on hospitalist RRT members, and reduced autonomy for trainees.
Conclusions The RRT provides advantages that extend well beyond a reduction in rates of transfers to intensive care units or codes but are balanced by certain disadvantages. The potential impact from these multiple sources should be evaluated to understand the utility of any RRT programme.

Rapid response teams (RRTs), also known as medical emergency teams or medical response teams, were developed to promote rapid assessment and treatment of patients whose clinical condition was deteriorating but who were not yet in shock or cardiac arrest.1 In 2004, the Institute for Healthcare Improvement included RRTs in its influential 100 000 Lives Campaign, and by the next year over 1400 American hospitals had implemented programmes.2 In 2008, RRTs became part of hospital accreditation by The Joint Commission.3
By making it easy to escalate care earlier, RRTs are thought to reduce mortality and codes occurring outside of intensive care units (ICUs).4–8 Despite these potential successes, the impact of RRTs has been questioned: some authors have casted doubt on the prudence of implementing RRTs without stronger evidence of improved outcomes.9–13 Existing studies have focused their measures of success on mortality and code rates4–8; however, RRTs may have substantial impact beyond these outcomes. For example, Donaldson et al described reasons staff nurses are in favour of RRTs—many of which may be only tangentially related to reducing mortality outside of intensive care (physical assistance, one-call mobilisation, competency of a critical care nurse, and expedited transfer of patients).14
Whether RRTs can decrease mortality and codes outside of the ICU represents only one component of their value. To create a comprehensive view of the impact and value of an RRT on a hospital and its staff, the objective of this study was to qualitatively describe the experiences of and attitudes held by nurses, physicians, administrators and staff regarding RRTs.
To broadly evaluate the RRT, we chose a qualitative methodological approach. Qualitative methodology provides a framework for developing exploratory studies to describe comprehension and behaviours that are based on complex beliefs that can be difficult to measure in a standardised quantitative manner.15 We conducted qualitative, open-ended interviews with nurses, physicians, RRT members, housestaff (both interns and resident physicians) and administrators during November 2008 to January 2009.
Yale-New Haven Hospital is an academic hospital in New Haven, Connecticut. During the period of this study, the hospital had 944 beds and 45 000 adult discharges per year covered by a medical staff of 1600 with an additional 500 affiliated physicians, 700 residents, 250 fellows, 1200 nurses for adult medical or surgical areas, and 21 senior administrators (7 of which had oversight for clinical areas).
The adult RRT was instituted in December 2005. During the period of this study, the team covered 43 patient-care units and received an average of 36.7 calls per 1000 discharges (figure 1). The RRT was composed of a hospitalist physician, a critical care ‘SWAT’ nurse, and a respiratory therapist. A ‘SWAT’ nurse is a resource nurse or ‘floater’ with >2 years of critical care experience. Our RRT could also be classified as a medical response team or medical emergency team because it included a physician. Our clinical administrative policy addressed the purpose, procedure, trigger-criteria and responsibilities for the RRT. If a patient met one of the trigger criteria, the patient's nurse was expected to call the RRT simultaneously with the primary team so that decisions could be made jointly. As of December 2008, the median response time was 2 min, the median time at the bedside was 56 min, 40% of calls occurred during the day, 35% during the evening and 25% at night.
As is standard in qualitative research, we used purposeful sampling to ensure that we included a diverse group of participants; we interviewed participants until no new concepts were identified by additional interviews (theoretical saturation).15 16
Participants were selected from administrators, registered nurses, senior attending physicians, housestaff and members of the adult RRT. Registered nurses were interviewed from four different medical units, two with a high rate of RRT activations and two with a low rate of RRT activations. We purposefully sought and interviewed staff with varied views based on the working knowledge of the Medical Director who was able to characterise people in favour of or opposed to the RRT.
In total, we interviewed 49 participants: 18 registered nurses, 8 administrators, 6 primary team senior attending physicians, 6 house staff members, 4 RRT attending physicians, 4 RRT critical care (SWAT) nurses, and 3 RRT respiratory technicians. After obtaining consent, one investigator (CPB) conducted and recorded private interviews with each participant. Interviews (except for those with hospital administrators) began with a request to describe a recent or memorable experience when the participant had been involved with an RRT. Standard open-ended questions and probes were used to elicit a broad discussion about the RRT programme (Appendix).
Interviews were transcribed verbatim by an independent transcriptionist. Using the common coding techniques for qualitative data and the constant comparative method of qualitative data analysis, we elicited from the interviews a list of major thematic categories and subcategories.15 After a comprehensive coding structure had been established, researchers met in pairs (each researcher met with every other) to formally code each interview line-by-line. As new themes were elicited, the group reconvened, reviewed the themes, and made iterative changes to the coding structure; disagreements in coding were resolved through negotiated consensus. After all interviews had been coded and the taxonomy was complete, all authors met again to refine and to finalise the coding structure. A qualitative software coding programme (Atlas-TI, GmbH, Germany) was used to retrieve and organise quotations.
The project was approved by the Yale School of Medicine Human Investigation Committee. Written informed consent was obtained from all participants.
Themes elicited from interviews were categorised into the broad domains of morale and teamwork, education, workload, patient care, and hospital administration (table 1). Within each domain, themes emerged in the subcategories of positive and negative implications. In addition, interviewees identified suggestions for improving the programme (table 2).
Morale and teamwork
Positive implications: improved morale for nurses
A major theme that emerged for nurses was a sense of security and of empowerment generated by knowing skilled backup was available immediately through a single phone call. In the words of one nurse: “It's very comforting to have someone help us to assess the patient … to make the decision that the person is too sick to remain on the floor … and to support us.” This theme was echoed by both physicians and administrators. One hospitalist said, “(The nurses) actually have something they can do about it versus just kind of watching the patient flounder.”
The availability of the RRT empowered nurses who were able to obtain additional help without having to request permission. As one nurse explained, “I don't usually hesitate to call. I notify the team of any changes, and if I feel like I need additional nursing support or if I need respiratory support right that minute, I will call an RRT.” In the words of one senior leader: “When a nurse says, ‘I know my patient and something doesn't seem right,’ and picks up a phone to call a rapid response—that is, part of creating the work environment where the voice of nurse is heard and respected.”
Negative implications: conflict between primary team and nurse or RRT
While the RRT improved morale for nurses, it was also perceived to increase conflict between nurses and physicians. Some primary team physicians felt that nurses called the RRT inappropriately instead of calling the physicians who were the primary team and thus better suited to caring for the patient. This reduced the primary team members' ability to perform their role in caring for patients.
I know that it's made more tension between nursing and housestaff … [The nurses] always … apologised when they were calling one [RRT] because … they knew it upset us … it gave us so much more work and that we sort of philosophically disagreed with why they were calling them many times. (PGY-3 resident)
Consequently, some primary teams discouraged the nurse from calling an RRT regardless of the severity of the situation:
The attending pulled me aside during the RRT to basically reprimand me for going above his head … even though I needed that extra support and I knew I should have called the RRT much earlier in the day … That's a barrier in calling an RRT, which could affect the patient's outcome. (Nurse)
In contrast, nurses often viewed the RRT as a solution to pre-existing problems with nurse–physician teamwork. Nurses reported feeling as though they sometimes tried going through the correct channels with the housestaff without a satisfactory outcome:
The patient was decompensating and during rounds I tried to express my concerns and my observations to the medical team … The patient continued to decompensate through the morning and I called the team every 5 min basically. With really no support and response … The patient was having trouble breathing; the patient's abdomen was distended and firm … So by lunch time, I had spent most of my morning with this patient … I ended up calling an RRT, which probably should have been called 3 h earlier. (Nurse)
Several nurses felt this tension derived from a perception by physicians that a call to the RRT implied a failure on the part of the physician. In contrast, nurses were very practical about using it as a way to get another set of experienced eyes and hands:
I don't think it's that they don't appreciate the help from the hospitalist attending who shows up, because the hospitalist attending never really dictates care … But I think physicians look at it as they're not doing the best job that they can be doing. Instead of looking at it as help. (Nurse)
Despite these issues, nurses reported that the tensions improved over the years since the initial implementation of the programme:
Sometimes they … have a bit of an attitude thing, “Oh I can handle this. This is my patient. I know this patient. I didn't want a rapid response to be called.” You know, we get a fair amount of that, but not as much as we did in the beginning. In the beginning … nurses were getting yelled at by the primary team like, “How dare you call a rapid response on my patient?” … They seem to be more receptive now. (SWAT nurse)
Positive implications: educational tool
For both nurses and physicians, the RRT intervention could be used as a learning tool; and in particular, was seen as a good way to support and nurture junior nurses:
From an educational standpoint, you have seasoned people who can teach the younger physicians or residents how you approach someone like this. (Attending)
As a SWAT nurse … you have a little bit more time where once the rapid response is finished up, you are then able to go back to the nurse who initially called the rapid response and say, “You know, hey either that was a great job and you were really were dead-on with your call.” Or, “These are some things that maybe [you] could have done before the rapid response was called to help better the situation.” (SWAT nurse)
The hospitalists who rotated being on call for the RRT also appreciated the ongoing exposure to acutely decompensating patients as a way to make sure that their skills remained up to date. In the words of one hospitalist, “So just to kind of keep up some of the skills of, you know, when there's … a more difficult situation.”
Negative implications: detriment to education of housestaff
Because the RRT served to escalate care rapidly to the most experienced clinicians, physicians felt that physician learners were not being adequately exposed to the decision-making process that is a requisite part of learning to be an independent physician. Teaching about thought processes was being lost in the effort to expedite care for patients and the traditional teaching approach to care was upended:
The intern is the front line in the hospital … the one who goes, assesses the situation, tries to come up with a treatment plan and implements it under the auspices of a senior resident and an attending … Very rarely on the floors is a situation so dire that an intern can't have 15 min to try to figure out a treatment plan … unfortunately what's happening with the RRTs is … RRTs are being called, a team is rushing in and barking orders, and the intern then is left in the dust. (PGY-3 resident)
Positive implications: redistribution of nurses' workload
An important effect of the RRT was that it facilitated a redistribution of the workload for nurses. When a patient was very sick, it could take substantial effort by multiple nurses to attend to that patient. Consequently, the focus on the sick patient may divert resources from the other patients on the unit:
I had pushed a couple of medications and still could not get the heart rate down … once you start doing a few medications and doing the follow-up, you're watching the clock (and it had been about an hour, an hour and a half) … I'm starting to just focus on that 1 patient … we're hurting our other 4 patients … At the same, I had called in another nurse … now her 4 patients are not seeing the care that they should … So you're looking at maybe 8 patients now. (Nurse)
Repeatedly, interviewees described how the RRT provided nurses a way to realign the workload and to ensure that other patients were not being neglected.
Positive implications: balance of physician workload
Just as for nurses, acutely ill patients required a great deal of attention from physicians, potentially diverting their attention from other patients. This was a particular problem on nights and weekends when physicians already carried a larger workload. Physicians also noted the value of the RRT in providing expert assistance from both physicians and nurses in these situations.
I feel like the rapid responses that I've been involved in are in the middle of the night, and I'm tired and everyone's really busy, and we've got people coming up from the ED, and it's just … we need to get these people safe so we can go attend to our other people. (Intern)
I think that sometimes you legitimately need more help. When I'm here on the weekend as the only resident … I'm responsible for 40 very sick patients alone. (PGY-3 resident)
Negative implications: burden to RRT members
The RRT was staffed by hospitalists who also carryied their own patient load during their shift. For this reason, many hospitalists described a negative impact of RRT calls on their workload.
[The RRT] is not our only clinical responsibility for the day … it implies that at any time in your day, you drop that other patient; that other family; that other conversation … and you run to these situations … it's extremely disruptive … You see how huge this place is … it takes 10 min with the way the elevators work in this hospital to get to 5-2 [another patient unit] … So I think it's just a huge, huge stressor in terms of having physicians do it who are clinically responsible for others. (Hospitalist)
Positive implications: escalation of care for patients
The majority of participants described a positive impact of the RRT for patients in facilitating rapid escalation of care. Escalation of care took multiple forms: patients who were becoming increasingly acutely ill received necessary care in an expedited fashion, transfer to the ICU was smoother, and patient-safety could be ensured. In particular, participants articulated that the RRT provided a formalised process for escalating care that was more effective than earlier models. In the past, SWAT nurses had been available for help, and consults from the ICU were also available. These processes, however, could be erratic or dependent on personal relations or complicated politics. Formalising the mechanism for escalating care to an RRT with appropriate expertise and devising a means for having them arrive in timely fashion meant that escalation of care was more effective and efficient. In the words of one administrator:
What the rapid response teams have done is sort of implement a more rational and planned approach to that previous sort of ‘Helter-skelter’ approach … “Well, I gotta find the respiratory therapist.” One call really precipitates team action … We were actually able to implement the team, teams without resource additions, because this work was [already] getting done in a slightly less-organised fashion. (Administrator)
Providers repeatedly described examples when a patient had begun deteriorating and quickly received more efficient and effective care and/or transfer than would have been possible in the days before the RRT programme.
It's gotten [patients] to safer levels of care within the hospital. For example, that patient … who needed to go back to the OR—the physicians caring for her were not willing to see that she was in distress … getting that outside opinion really helped them reevaluate the situation and move her to where she really needed to be. (SWAT nurse)
Negative implications: errors and delays due to lack of continuity
A few primary attendings felt that their plans for patients were disrupted by the RRT and caused disjointed care for the patients.
The RRT teams would have made mistakes had we not been there because they didn't know the patient… they came in, diligent though they were, listened to the patient's lungs… and wanted to give the patient some diuretic to get the fluid out. We knew that this patient had a chronic lung process, for the rales were always there. The patient had renal failure and it would have been a bad idea to give the diuretic. And so my concern is that although there are times when RRT certainly makes sense, I think you're much better off dealing with someone who knows the patient. (Primary attending)
In addition, it could be very time consuming for RRT members to get adequately briefed on the pertinent medical history of the patient. As one intern said, “They're not familiar with the patient. It takes them too long to look in the chart and figure out what's going on.”
In addition to the above themes, there were two ideas that emerged from hospital administrators that were specifically about creating a positive impact for the hospital as a whole.
Positive implications: patient flow
Administrators reported that the RRT served as a centralised mechanism to triage which patients should go to the ICU. In this manner, the RRT helped to manage the flow to the ICU beds, as well as averting some transfers altogether. As one administrator said:
If we can stabilise patients who become unstable before they require ICU transfer, then we leave that bed open for a patient from another place and are better able to handle incoming patients and patients from our ORs. (Administrator)
Positive implications: nursing retention
Administrators described that the RRT programme played an important role in retention of nurses:
We do have data that over the last couple years nurse retention has improved and nurse turnover has declined. We also have … interviews with our staff nurses about the rapid response teams. That they really feel like somebody has their back … they have somebody to call. (Administrator)
Suggestions for improvement
A number of suggestions emerged from the interviews about how to improve the RRT as it was implemented. These suggestions are listed in table 2 and many correspond directly to the themes about negative impact described above.
In this qualitative study, we found that the positive impact of the existing implementation of the RRT for adult patients at our hospital extended well beyond a reduction in mortality or rates of codes. The RRT expedited effective care for acutely ill patients, ensured other patients were not neglected, improved morale and perhaps retention of nurses, facilitated hospital throughput and provided learning opportunities for nurses and physicians alike. At the same time, this study of the RRT showed some disadvantages: tensions may develop between floor nurses and primary teams, the RRT was perceived to have disruptive effects on trainee autonomy and education, and RRT members may have an excessive workload. Based on this information, we were able to target improvements to our RRT programme by emphasising decreasing tensions between teams, reviewing the distribution of workload for team members and others, and developing an integrated approach to education for both nurses and physicians to engage them in the RRT.
Some of the disadvantages to the RRT programme elicited by this study may be specific to the environment of a teaching hospital. In particular, negative comments focused on lack of continuity of care and changes in traditional teaching approaches. This tension between clinical teaching and patient-safety is not new—longstanding controversies in this regard are exemplified by the debates over resident duty hours.17 18 Patient-safety, however, does not need to preclude learning; and strategies to mitigate these disadvantages were suggested by interviewees, such as placing trainees on the RRT and using the event of an RRT as a teaching tool. To ensure that the education of physician or nurse trainees does not occur at the expense of patient-safety and timely, quality care, we have used the information from this study to instigate expanded efforts in simulation with scenarios focused on clinical deterioration. Moreover, the experience of interviewees indicates that, over time, providers get used to the RRT and that many of the problems and conflicts abate.
The results of this study begin to address the question of how we define success for RRTs—should RRTs be evaluated on outcomes beyond a reduction in codes or mortality? Studies touting the success4–8 19–24 or failure9 10 12 25–27 of RRTs have typically relied on these narrowly defined, quantitative determinants of success. The results of our study, however, show that relying entirely on these outcomes neglects numerous consequences—many quite valuable—of implementing the RRT. The RRT has effectively organised and streamlined work for those who care for the clinically deteriorating patient. This has led to ancillary benefits to staff morale, allowed increased attention to non-acutely ill patients, improved hospital throughput, and enhanced education. Our thoughtful assessment of negative aspects has also engaged staff and facilitated programme improvement. Together, looking at all of these outcomes, positive and negative, we believe the RRT promotes the ‘safety culture’ at our hospital. Some of these outcomes have been partially assessed in earlier studies,14 28 but comprehensive evaluation of all participants, such as was done in this study, are rare. Many of the positive and negative implications that we delineated qualitatively can and should be assessed quantitatively in future evaluations of any RRT programme to fully understand its value.
These qualitatively derived endpoints may also lend insight into the numerous reports of RRT failures.9 10 12 25–27 As several authors have noted, the nature of the implementation of the RRT programme has a profound effect on programme outcomes.11 29 RRT programmes vary from ‘robust’ to ‘challenged’,14 depending on the extent of cultural change present in the hospitals. Our study suggests several metrics by which implementation and culture can be assessed, including belief in effectiveness of RRT, relationship between nurses and physicians, response of physicians to nurse calling the RRT, willingness of nurses to call the RRT, morale, perceptions of workload distribution and others. Similar factors have been assessed in some studies of ‘challenged’ implementations.28 30 31
The limitations of the study were related to generalisability and are typical to qualitative and quality improvement research. We included a purposeful sample from one hospital and one implementation of an adult RRT programme. However, the generalisability of qualitative work is not intended to derive from a statistically representative sample; instead, qualitative work should describe in depth a full range of attitudes to create a theoretical understanding of an issue. To maximise the validity of our findings, we used the methodological techniques of purposeful sampling, grounded theory and coding by multiple researchers who came to agreement on the coding structure. Future work could evaluate the prevalence of the different themes across a wider spectrum of hospitals.
Future evaluations of the impact of any RRT programme should include assessment of outcomes beyond those of codes and mortality. Efforts must include evaluation of the impact on morale of nurses, speed of escalation of care for acutely ill patients, tensions between teams, distribution of workload, education for nurses and physicians, and appropriate care for patients not involved in the RRT.
