Rapid response teams, do not resuscitate orders, and potential opportunities to improve end-of-life care: a multicentre retrospective study

Rapid response system and mortality in intensive care unit: a nationwide cohort study in South Korea

The beneficial effects of a rapid response system (RRS) on clinical outcomes in patients admitted to a ward have been established. However, the relationship between RRS implementation and clinical outcomes in patients in the intensive care unit (ICU) has not yet been established. Therefore, we aimed to investigate whether the RRS affects clinical outcomes in critically ill patients admitted to the ICU. As a nationwide, population-based cohort study, all adult patients who were admitted to the ICU from 1 January 2019 to 31 December 2021 in South Korea were included. Patients in hospitals with an RRS formed the RRS group; those in hospitals lacking an RRS constituted the non-RRS group. In total, 900,606 patients admitted to the ICU were included in the final analysis. Among them, 365,305 (40.6%) were assigned to the RRS group, and 535,301 (59.4%) were assigned to the non-RRS group. After propensity score (PS) matching, a total of 454,748 patients (227,374 in each group) were included in the final analysis. In the PS-matched cohort, the RRS group showed 8% (odds ratio [OR]: 0.92, 95% confidence interval [CI]: 0.91, 0.94; P < 0.001) and 11% (hazard ratio: 0.89, 95% CI: 0.88, 0.90; P < 0.001) lower in-hospital mortality rates and 1-year all-cause mortality rates than the non-RRS group, respectively. In addition, ICU readmission rates and the occurrence rate for adverse events during hospitalization in the RRS group were 3% (OR: 0.97, 95% CI: 0.95, 0.98; P < 0.001) and 21% (OR: 0.79, 95% CI: 0.78, 0.80; P < 0.001) lower than those in the non-RRS group, respectively. RRS deployment was linked to lower in-hospital and 1-year all-cause mortality rates, ICU readmission rates, and the occurrence of adverse events during hospitalization among ICU patients. The findings indicate that using the RRS could assist not only patients in the ward but also critically ill patients in the ICU.

Oncology Intensive Care Units: Distinguishing Features and Clinical Considerations

The rapidly advancing field of cancer therapeutics has led to increased longevity among cancer patients as well as increasing complexity of cancer-related illness and associated comorbid conditions. As a result, institutions and organizations that specialize in the in-patient care of cancer patients have similarly evolved to meet the constantly changing needs of this unique patient population. Within these institutions, the intensive care units that specialize in the care of critically ill cancer patients represent an especially unique clinical resource. This article explores some of the defining and distinguishing characteristics associated with oncology ICUs.

The associations between rapid response systems and their components with patient outcomes: A scoping review

Background

While rapid response systems have been widely implemented, their impact on patient outcomes remains unclear. Further understanding of their components-including medical emergency team triggers, medical emergency team member composition, additional roles in patient care beyond responding to medical emergency team events, and their involvement in "Do-Not-Resuscitate" order placement-may elucidate the relationship between rapid response systems and outcomes.

Objective

To explore how recent studies have examined rapid response system components in the context of relevant adverse patient outcomes, such as in-hospital cardiac arrests and hospital mortality.

Design

Scoping review.

Methods

PubMed, CINAHL, and Embase were searched for articles published between November 2014 and June 2022. Studies mainly focused on rapid response systems and associations with in-hospital cardiac arrests were considered. The following were extracted for analysis: study design, location, sample size, participant characteristics, system characteristics (including medical emergency team member composition, additional system roles outside of medical emergency team events), medical emergency team triggers, in-hospital cardiac arrests, and hospital mortality.

Results

Thirty-four studies met inclusion criteria. While most studies described triggers used, few analyzed medical emergency team trigger associations with outcomes. Of those, medical emergency team triggers relating to respiratory abnormalities and use of multiple triggers to activate the medical emergency team were associated with adverse patient outcomes. Many studies described medical emergency team member composition, but the way composition was reported varied across studies. Of the seven studies with dedicated medical emergency team members, six found their systems were associated with decreased incidence of in-hospital cardiac arrests. Six of seven studies that described additional medical emergency team roles in educating staff in rapid response system use found their systems were associated with significant decreases in adverse patient outcomes. Four of five studies that described proactive rounding responsibilities reported found their systems were associated with significant decreases in adverse patient outcomes. Reporting of rapid response system involvement in "Do-Not-Resuscitate" order placement was variable across studies.

Conclusions

Inconsistencies in describing rapid response system components and related data and outcomes highlights how these systems are complex to a degree not fully captured in existing literature. Further large-scale examination of these components across institutions is warranted. Development and use of robust and standardized metrics to track data related to rapid response system components and related outcomes are needed to optimize these systems and improve patient outcomes.

An Exploratory Investigation into the Roles of Critical Care Response Teams in End-of-Life Care

Background

Critical Care Response Teams (CCRTs) represent an important interface between end-of-life care (EOLC) and critical care medicine (CCM). The aim of this study was to explore the roles and interactions of CCRTs in the provision of EOLC from the perspective of CCRT members.

Methods

Twelve registered nurses (RNs) and four respiratory therapists (RTs) took part in focus groups, and one-on-one interviews were conducted with six critical care physicians. Thematic coding using a modified constructivist grounded theory approach was used to identify emerging themes through an iterative process involving a four-member coding team.

Results

Three main perspectives were identified that spoke to CCRT interactions and perceptions of EOLC encounters. CCRT members felt that they provide a unique skill set of multidisciplinary expertise in treating critically ill patients and evaluating the utility of intensive care treatments. However, despite feeling that they possessed the skills and resources to deliver quality EOLC, CCRT members were ambivalent with respect to whether EOLC was a part of their mandate. Challenges were also identified that impacted the ability of CCRTs to deliver quality EOLC.

Conclusions

This research aids in understanding for the first time CCRT roles in EOLC from the perspectives of individual CCRT members themselves. While CCRTs provide unique multidisciplinary expertise to evaluate the utility of intensive care treatments, opportunities exist to support CCRTs in EOLC, such as dedicated EOLC training, protocols for advance care planning, documentation, and transitions to palliative care.

Risk Factors for Early Medical Emergency Team Reactivation in Hospitalized Patients

OBJECTIVES

The objective of this study was to investigate the risk factors for early medical emergency team reactivation (which is defined as repeated medical emergency team calls within 72 hr after the index medical emergency team call) in the patients remaining on the ward after index medical emergency team activation.

DESIGN

Retrospective analysis with prospectively collected data.

SETTING

A university-affiliated, tertiary referral hospital.

PATIENTS

All consecutive patients over 18 years old who received medical emergency team intervention.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of the 3,989 cases eligible for analysis, 514 cases (12.9%) were classified into the reactivation group, with the remainder assigned to the nonreactivation group. In a multivariate analysis, chronic lung disease (odds ratio, 1.38; 95% CI, 1.03-1.86; p = 0.032), chronic liver disease (odds ratio, 1.44; 95% CI, 1.04-1.99; p = 0.028), activation due to bedside concern about overall deterioration without abnormal physiological variables (odds ratio, 1.30; 95% CI, 1.00-1.68; p = 0.049), advice or consultation only for medical emergency team intervention (odds ratio, 0.78; 95% CI, 0.63-0.97; p = 0.027), and discussion about treatment limitation (odds ratio, 0.39; 95% CI, 0.25-0.60; p < 0.001) were independently associated with medical emergency team reactivation. In the reactivation group, 249 patients (48.5%) were transferred to the ICU after repeated calls. Medical department admission (odds ratio, 1.68; 95% CI, 1.12-2.52; p = 0.012), chronic liver disease (odds ratio, 1.73; 95% CI, 1.07-2.79; p = 0.025), hematological malignancies (odds ratio, 1.63; 95% CI, 1.10-2.41; p = 0.015), and tachypnea at the end of medical emergency team were risk factors for medical emergency team reactivation requiring ICU admission. Discussion about treatment limitation (odds ratio, 0.14; 95% CI, 0.05-0.40; p < 0.001) was also associated with decreased risk of medical emergency team reactivation requiring ICU admission.

CONCLUSIONS

An increased risk of early medical emergency team reactivation was associated with medical emergency team activation by bedside concern about overall deterioration and patients with chronic lung or liver disease.

Intensity of Vasopressor Therapy and In-Hospital Mortality for Infants and Children: An Opportunity for Counseling Families

CONTEXT

Most pediatric deaths occur in an intensive care unit, and treatment specific predictors of mortality could help clinicians and families make informed decisions.

OBJECTIVE

To investigate whether the intensity of vasopressor therapy for pediatric patients, regardless of diagnosis, predicts in-hospital mortality.

METHODS

Single-center, retrospective medical chart review of children aged 0-17 who were admitted between 2005 and 2015 at a pediatric tertiary care center in the U.S. and received any vasopressor medication-dopamine, dobutamine, epinephrine, vasopressin, norepinephrine, or hydrocortisone.

RESULTS

During the 10-year period, 1654 patients received at least one vasopressor medication during a hospitalization. Median age at the time of hospitalization was three months, and the median duration of hospitalization was 23 days; 8% of patients had two to five hospitalizations in which they received vasopressors. There were 176 total patients who died while receiving vasopressors; most (93%) died during their first hospitalization. The most common diagnosis was sepsis (34%), followed by congenital heart disease (17%). Dopamine was the most commonly prescribed first-line vasopressor (70%), and hydrocortisone was the most commonly prescribed second-line vasopressor (49%) for all pediatric patients. The incidence of mortality rose sequentially with escalating vasopressor support, increasing from under 10% with the first vasopressor to 48% at the maximum number of agents. The odds of death almost doubled with the addition of each new vasopressor.

CONCLUSIONS

The intensity of vasopressor therapy for pediatric patients, regardless of diagnosis, is associated with in-hospital mortality; vasopressor escalation should trigger intensive palliative care supports.

The association between hospital length of stay before rapid response system activation and clinical outcomes: a retrospective multicenter cohort study

Background

Rapid response system (RRS) is being increasingly adopted to improve patient safety in hospitals worldwide. However, predictors of survival outcome after RRS activation because of unexpected clinical deterioration are not well defined. We investigated whether hospital length of stay (LOS) before RRS activation can predict the clinical outcomes.

Methods

Using a nationwide multicenter RRS database, we identified patients for whom RRS was activated during hospitalization at 9 tertiary referral hospitals in South Korea between January 1, 2016, and December 31, 2017. All information on patient characteristics, RRS activation, and clinical outcomes were retrospectively collected by reviewing patient medical records at each center. Patients were categorized into two groups according to their hospital LOS before RRS activation: early deterioration (LOS < 5 days) and late deterioration (LOS ≥ 5 days). The primary outcome was 28-day mortality and multivariable logistic regression was used to compare the two groups. In addition, propensity score-matched analysis was used to minimize the effects of confounding factors.

Results

Among 11,612 patients, 5779 and 5883 patients belonged to the early and late deterioration groups, respectively. Patients in the late deterioration group were more likely to have malignant disease and to be more severely ill at the time of RRS activation. After adjusting for confounding factors, the late deterioration group had higher 28-day mortality (aOR 1.60, 95% CI 1.44–1.77). Other clinical outcomes (in-hospital mortality and hospital LOS after RRS activation) were worse in the late deterioration group as well, and similar results were found in the propensity score-matched analysis (aOR for 28-day mortality 1.66, 95% CI 1.45–1.91).

Conclusions

Patients who stayed longer in the hospital before RRS activation had worse clinical outcomes. During the RRS team review of patients, hospital LOS before RRS activation should be considered as a predictor of future outcome.

End-of-life care and intensive care unit clinician involvement in a private acute care hospital: A retrospective descriptive medical record audit

INTRODUCTION

More Australians die in the hospital than in any other setting. This study aimed to (i) evaluate the quality of end-of-life (EOL) care in the hospital against an Australian National Standard, (ii) describe the characteristics of intensive care unit (ICU) clinician involvement in EOL care, and (iii) explore the demographic and clinical factors associated with quality of EOL care.

METHOD

A retrospective descriptive medical record audit was conducted on 297 adult inpatients who died in 2017 in a private acute care hospital in Melbourne, Australia. Data collected related to 20 'Processes of Care', considered to contribute to the quality of EOL care. The decedent sample was separated into three cohorts as per ICU clinician involvement.

RESULTS

The median age of the sample was 81 (25th-75th percentile = 72-88) years. The median tally for EOL care quality was 16 (25th-75th percentile = 13-17) of 20 care processes. ICU clinicians were involved in 65.7% (n = 195) of cases; however, contact with the ICU outreach team or an ICU admission during the final inpatient stay was negatively associated with quality of EOL care (coefficient = -1.51 and -2.07, respectively). Longer length of stay was positively associated with EOL care (coefficient = .05). Specialist palliative care was involved in 53% of cases, but this was less likely for those admitted to the ICU (p < .001). Evidence of social support, bereavement follow-up, and religious support were low across all cohorts.

CONCLUSION

Statistically significant differences in the quality of EOL care and a negative association between ICU involvement and EOL care quality suggest opportunities for ICU outreach clinicians to facilitate discussion of care goals and the appropriateness of ICU admission. Advocating for inclusion of specialist palliative care and nonclinical support personnel in EOL care has merit. Future research is necessary to investigate the relationship between ICU intervention and EOL care quality.

Adoption of a dedicated multidisciplinary team is associated with improved survival in acute pulmonary embolism

BACKGROUND

Acute pulmonary embolism remains a significant cause of mortality and morbidity worldwide. Benefit of recently developed multidisciplinary PE response teams (PERT) with higher utilization of advanced therapies has not been established.

METHODS

To evaluate patient-centered outcomes and cost-effectiveness of a multidisciplinary PERT we performed a retrospective analysis of 554 patients with acute PE at the university of Virginia between July 2014 and June 2015 (pre-PERT era) and between April 2017 through October 2018 (PERT era). Six-month survival, hospital length-of-stay (LOS), type of PE therapy, and in-hospital bleeding were assessed upon collected data.

RESULTS

317 consecutive patients were treated for acute PE during an 18-month period following institution of a multidisciplinary PE program; for 120 patients PERT was activated (PA), the remaining 197 patients with acute PE were considered as a separate, contemporary group (NPA). The historical, comparator cohort (PP) was composed of 237 patients. These 3 groups were similar in terms of baseline demographics, comorbidities and risk, as assessed by the Pulmonary Embolism Severity Index (PESI). Patients in the historical cohort demonstrated worsened survival when compared with patients treated during the PERT era. During the PERT era no statistically significant difference in survival was observed in the PA group when compared to the NPA group despite significantly higher severity of illness among PA patients. Hospital LOS was not different in the PA group when compared to either the NPA or PP group. Hospital costs did not differ among the 3 cohorts. 30-day re-admission rates were significantly lower during the PERT era. Rates of advanced therapies were significantly higher during the PERT era (9.1% vs. 2%) and were concentrated in the PA group (21.7% vs. 1.5%) without any significant rise in in-hospital bleeding complications.

CONCLUSIONS

At our institution, all-cause mortality in patients with acute PE has significantly and durably decreased with the adoption of a PERT program without incurring additional hospital costs or protracting hospital LOS. Our data suggest that the adoption of a multidisciplinary approach at some institutions may provide benefit to select patients with acute PE.

Unplanned Admission to the ICU: A Qualitative Study Examining Family Member Experiences

BACKGROUND

Transfers to the ICU from acute care are common, and it is essential to understand how family members of critically ill patients experience these transitions of care.

RESEARCH QUESTION

Can we enhance our understanding of family members' experiences during hospital stays complicated by a patient's unplanned admission to the ICU?

STUDY DESIGN AND METHODS

Qualitative interviews were conducted with family members of patients were transferred from acute care to the ICU at a level I trauma center in Seattle, WA (n = 17). To organize data, we used thematic analysis, coupled with a validated conceptual model of clinician-surrogate communication.

RESULTS

Drawing from a validated conceptual model, we used two domains to frame our coding: "information processing" and "relationship building." Within information processing, we coded information disclosure, sensemaking, and expectations; within relationship building, we coded emotional support, trust, and consensus and conflict. Family members wanted timely, accurate information about the patient's condition both during and after transfer. An unplanned ICU admission was a stressful event for family members, who looked to clinicians for emotional support. Developing trust was challenging, because family members struggled to feel like integrated members of the medical team when patients transitioned from one setting to another.

INTERPRETATION

Family of patients who experience an unplanned ICU admission want high-quality communication both during and after a patient's transfer to the ICU. This communication should help family members make sense of the situation, address unmet expectations, and provide emotional support. In addition, interventions that foster family-clinician trust can help family members feel like integrated members of the care team as they face the challenge of navigating multiple different environments within the hospital.

Role of the Rapid Response System in End-of-Life Care Decisions

PURPOSE

An important role of the rapid response system (RRS) is to provide opportunities for end-of-life care (EOLC) decisions to be appropriately operationalized. We investigated whether EOLC decisions were made after the RRS-recommended EOLC decision to the primary physician.

MATERIALS AND METHODS

We studied whether patients made EOLC decisions consistent with the rapid response team's (RRT) recommendations, between January 1, 2017, and February 28, 2019. The primary outcome was the EOLC decision after the RRT's recommendation to the primary physician. The secondary outcome was the mechanism of EOLC decision-making: through institutional do-not-resuscitate forms or the Korean legal forms of Life-Sustaining Treatment Plan (LSTP).

RESULTS

Korean LSTPs were used in 26 of the 58 patients who selected EOLC, from among the 75 patients for whom the RRS made an EOLC recommendation. Approximately 7.2% of EOLC decisions for inpatients were related to the RRT's interventions in EOLC decisions. Patients who made EOLC decisions did not receive cardiopulmonary resuscitation, mechanical ventilation, or dialysis.

CONCLUSION

The timely intervention of the RRS in EOLC facilitates an objective assessment of the patient's medical conditions, the limitation of treatments that may be minimally beneficial to the patient, and the choice of a higher quality of care. The EOLC decision using the legal process defined in the relevant Korean Act has advantages, wherein patients can clarify their preference, the family can prioritize the patient's preference for EOLC decisions, and physicians can make transparent EOLC decisions based on medical evidence and informed patient consent.

Rapid response team trigger modifications: are we using them safely?

BACKGROUND

Rapid response teams (RRT) were first proposed as a means of reducing inpatient morbidity and mortality. Modifying RRT activation triggers poses a potential risk for delayed recognition of a deteriorating patient. Trigger modifications have not been validated for safety.

AIMS

To determine if RRT trigger modifications are associated with: increased frequency of recurrent RRT activation; increased length of stay (LOS); increased intensive care admission; and increased in-hospital mortality.

METHODS

A retrospective audit of all RRT activations occurring at the Launceston General Hospital (LGH) over an 18-month period was performed.

RESULTS

Rate of recurrent RRT activations did not decrease with the use of trigger modifications around the time of RRT activation, and for patients with two modifications, the frequency increased (1.98 vs 1.32, P = 0.007). LGH LOS increased for patients with any trigger modifications compared to those with none (11 vs 9, P = 0.0002), and for patients with two modifications (11.5 vs 9, P = 0.010). Total hospital LOS increased for patients with any modifications compared to patients with none (12 vs 10, P = 0.002). There was no significant association between trigger modifications and frequency of intensive care unit admission. The relative risk of in-hospital death increased with increasing numbers of trigger modifications (relative risk 1.38-4.89).

CONCLUSIONS

Trigger modifications are associated with increased hospital LOS and increased rate of in-hospital death and do not reduce the number of recurrent events. For patients in whom escalation of care is not appropriate, the presence of multiple trigger modifications at the time of an RRT activation may be a useful trigger for conversations around goals of care.

Pragmatic methods to avoid intensive care unit admission when it does not align with patient and family goals

For patients with chronic, life-limiting illnesses, admission to the intensive care unit (ICU) near the end of life might not improve patient outcomes or be consistent with patient and family values, goals, and preferences. In this context, advance care planning and palliative care interventions designed to clarify patients' values, goals, and preferences have the potential to reduce provision of high-intensity interventions that are unwanted or non-beneficial. In this Series paper, we have assessed interventions that are effective at helping patients with chronic, life-limiting illnesses to avoid an unwanted ICU admission. The evidence found was largely from observational studies, with considerable heterogeneity in populations, methods, and types of interventions. Results from randomised trials of interventions to improve communication about goals of care are scarce, of variable quality, and mixed. Although observational studies show that advance care planning and palliative care interventions are associated with a reduced number of ICU admissions at the end of life, causality has not been well established. Using the available evidence we suggest recommendations to help to avoid ICU admission when it does not align with patient and family values, goals, and preferences and conclude with future directions for research.

Advance care planning in the context of clinical deterioration: a systematic review of the literature

Background:

A Rapid Response Team can respond to critically ill patients in hospital to prevent further deterioration and unexpected deaths. However, approximately one-third of reviews involve a patient approaching the end-of-life. It is not well understood whether patients have pre-existing advance care plans at the time of significant clinical deterioration requiring Rapid Response Team review. Nor is it understood whether such critical events prompt patients, their families and treating teams to discuss advance care planning and consider referral to specialist palliative care services.

Aim and design:

This systematic review examined advance care planning with patients who experience significant clinical deterioration in hospital and require Rapid Response Team review. The prevalence of pre-existing advance directives, whether this event prompts end-of-life discussions, the provision of broader advance care planning and referral to specialist palliative care services was examined.

Data sources:

Three electronic databases up to August 2017 were searched, and a manual review of article reference lists conducted. Quality of studies was appraised by the first and fourth authors.

Results:

Of the 324 articles identified through database searching, 31 met the inclusion criteria, generating data from 47,850 patients. There was a low prevalence of resuscitation orders and formal advance directives prior to Rapid Response Team review, with subsequent increases in resuscitation and limitations of medical treatment orders, but not advance directives. There was high short- and long-term mortality following review, and low rates of palliative care referral.

Conclusions:

The failure of patients, their families and medical teams to engage in advance care planning may result in inappropriate Rapid Response Team review that is not in line with patient and family priorities and preferences. Earlier engagement in advance care planning may result in improved person-centred care and referral to specialist palliative care services for ongoing management.

The Quality of End-of-Life Care after Limitations of Medical Treatment as Defined by a Rapid Response Team: A Retrospective Cohort Study

BACKGROUND

Despite the increase in the identification of patients at the end of life after the introduction of rapid response team (RRT), there is doubt as to whether there has been an improvement in the quality of care offered to these patients. Proper end-of-life care is the next expected step after identifying patients who are dying.

OBJECTIVE

To evaluate the end-of-life care after limitations of medical treatment (LOMTs) as defined by an RRT.

DESIGN

This is a single-center retrospective cohort study at a tertiary teaching hospital in Porto Alegre, Brazil, from July 2014 to July 2016.

SETTING/SUBJECTS

We included 242 patients with an LOMT as defined by the RRT.

MEASUREMENTS

Outcomes of interest included symptoms and palliative measures after RRT review.

RESULTS

During the study period, there were 5396 calls to 2937 patients, representing 126 calls per 1000 hospital discharges. Of these calls, 4.9% (n = 242) resulted in an LOMT. The primary care team agreed with the LOMT decision proposed by the RRT in 91.7% of cases. Regarding end-of-life symptoms, 7.4% and 5.8% of patients presented with intense or moderate pain, respectively, and 62.4% of patients presented dyspnea in the last 48 hours of hospitalization. Less than 15% of patients received attention for their spiritual needs and/or received psychological support.

CONCLUSIONS

Our data reinforce the important role of RRTs in the identification of end-of-life patients with clinical deterioration. Despite the increase in the identification of these patients, the quality of end-of-life care needs to be improved.

Who Benefits from Aggressive Rapid Response System Treatments Near the End of Life? A Retrospective Cohort Study

BACKGROUND

Many patients near the end of life are subject to rapid response system (RRS) calls. A study was conducted in a large Sydney teaching hospital to identify a cutoff point that defines nonbeneficial treatment for older hospital patients receiving an RRS call, describe interventions administered, and measure the cost of hospitalization.

METHODS

This was a retrospective cohort of 733 adult inpatients with data for the period three months before and after their last placed RRS call. Subgroup analysis of patients aged ≥ 80 years was conducted. Log-rank, chi-square, and t-tests were used to compare survival, and logistic regression was used to examine predictors of death.

RESULTS

Overall, 65 (8.9%) patients had a preexisting not-for-resuscitation (NFR) or not-for-RRS order; none of those patients survived to three months. By contrast, patients without an NFR or not-for-RRS order had three-month survival probability of 71% (log-rank χ² 145.63; p < 0.001). Compared with survivors, RRS recipients who died were more likely to be older, to be admitted to a medical ward, and to have a larger mean number of admissions before the RRS. The average cost of hospitalization for the very old transferred to the ICU was higher than for those not requiring treatment in the ICU (US$33,990 vs. US$14,774; p = 0.045).

CONCLUSION

Identifiable risk factors clearly associated with poor clinical outcomes and death can be used as a guide to administer less aggressive treatments, including reconsideration of ICU transfers, adherence to NFR orders, and transition to end-of-life management instead of calls to the RRS team.

Rapid Response Events in Hospitalized Patients: Patient Symptoms and Clinician Communication

CONTEXT

Patients triggering rapid response team (RRT) intervention are at high risk for adverse outcomes. Data on symptom burden of these patients do not currently exist, and current symptom management and communication practices of RRT clinicians are unknown.

OBJECTIVES

We sought to identify the symptom experience of RRT patients and observe how RRT clinicians communicate with patients and their families.

METHODS

We conducted a prospective observational study from August to December 2015. Investigators attending RRT events measured frequencies of symptom assessment, communication, and supportive behaviors by RRT clinicians. As the rapid response event concluded, investigators measured patient-reported pain, dyspnea, and anxiety using a numeric rating scale of 0 (none) to 10 (most severe), with uncontrolled symptoms defined as numeric rating scale score of ≥4.

RESULTS

We observed a total of 52 RRT events. RRT clinicians assessed for pain during the event in 62% of alert patients, dyspnea in 38%, and anxiety in 21%. Goals of care were discussed during 3% of events and within 24 hours in 13%. For the primary outcome measure, at the RRT event conclusion, 44% of alert patients had uncontrolled pain, 39% had uncontrolled dyspnea, and 35% had uncontrolled anxiety.

CONCLUSION

Hospitalized patients triggering RRT events have a high degree of uncontrolled symptoms that are infrequently assessed and treated. Although these patients experience an acute change in medical status and are at high risk for adverse outcomes, goals-of-care discussions with RRT patients or families are rarely documented in the period after the events.

A pilot study of a Medication Rationalization (MERA) intervention

BACKGROUND

Many seriously ill and frail inpatients receive potentially inappropriate or harmful medications and do not receive medications for symptoms of advanced illness. We developed and piloted an interprofessional Medication Rationalization (MERA) approach to deprescribing inappropriate medications and prescribing appropriate comfort medications.

METHODS

We conducted a single-centre pilot study of inpatients at risk of 6-month mortality from advanced age or morbidity. The MERA team reviewed the patients' medications and made recommendations on the basis of guidelines. We measured end points for feasibility, acceptability, efficiency and effectiveness.

RESULTS

We enrolled 61 of 115 (53%) eligible patients with a mean age of 79.6 years (standard deviation [SD] 11.7 yr). Patients were taking an average of 11.5 (SD 5.2) medications before admission and had an average of 2.1 symptoms with greater than 6/10 severity on the revised Edmonton Symptom Assessment System. The MERA team recommended 263 medication changes, of which 223 (85%) were accepted by both the medical team and the patient. MERA team's recommendations resulted in the discontinuation of 162 medications (mean 3.1 per patient), dose changes for 48 medications (mean 0.9 per patient) and the addition of 13 medications (mean 0.2 per patient). Patients who received the MERA intervention stopped significantly more inappropriate medications than similar non-MERA comparison patients for whom data were collected retrospectively (3.1 v. 0.9 medications per patient, p < 0.01). The MERA approach was highly acceptable to patients and medical team members.

INTERPRETATION

The MERA intervention is feasible, acceptable, efficient and possibly effective for changing medication use among seriously ill and frail elderly inpatients. Scalability and effectiveness may be improved through automation and integration with medication reconciliation programs.

An exploration of medical emergency team intervention at the end of life for people with advanced cancer

PURPOSE

Recent advances in cancer therapies offer survival benefit when cure is no longer possible. The contribution of the Medical Emergency Teams (METs) in the context of advancing disease has received little empirical consideration. This study set out to explore MET intervention at the end of life for people with advanced cancer in an Australian comprehensive cancer centre, and its impact on quality of death.

METHOD

A retrospective medical chart review was undertaken to explore MET response for people with advanced (incurable) cancer nearing end of life. Occurrence of MET interventions at the end of life and a quality of death score were recorded for two randomly selected cohorts of patients, those who experienced a MET response within their last week of life (n = 50) and those who did not (n = 50).

RESULTS

The cohort who did not receive MET intervention had a significantly higher (better) quality of death score when compared with patients who did receive a MET intervention (p = 0.01). Within the cohort who received a MET intervention, a subgroup (n = 19) where the MET influenced end-of-life decision-making had a significantly higher quality of death score (p = 0.02) than patients in the MET cohort (n = 31) where the MET did not influence end-of-life care.

CONCLUSION

The contribution of the MET to end-of-life care for patients with cancer has not previously been reported. Further research is now needed to prospectively examine MET involvement at the end of life with consideration to quality of patient care and death, family experience, and support requirements of MET members.

Comprehensive cardiopulmonary life support (CCLS) for cardiopulmonary resuscitation by trained paramedics and medics inside the hospital

The cardiopulmonary resuscitation (CPR) guideline of comprehensive cardiopulmonary life support (CCLS) for management of the patient with cardiopulmonary arrest in adults provides an algorithmic step-wise approach for optimal outcome of the patient inside the hospital by trained medics and paramedics. This guideline has been developed considering the infrastructure of healthcare delivery system in India. This is based on evidence in the international and national literature. In the absence of data from the Indian population, the extrapolation has been made from international data, discussed with Indian experts and modified accordingly to ensure their applicability in India. The CCLS guideline emphasise the need to recognise patients at risk for cardiac arrest and their timely management before a cardiac arrest occurs. The basic components of CPR include chest compressions for blood circulation; airway maintenance to ensure airway patency; lung ventilation to enable oxygenation and defibrillation to convert a pathologic 'shockable' cardiac rhythm to one capable to maintaining effective blood circulation. CCLS emphasises incorporation of airway management, drugs, and identification of the cause of arrest and its correction, while chest compression and ventilation are ongoing. It also emphasises the value of organised team approach and optimal post-resuscitation care.

Epidemiology of in-hospital mortality in acute patients admitted to a tertiary-level hospital

BACKGROUND

Healthcare professionals may have difficulty in recognising the dying patient in acute care settings, and yet, this is essential if timely end-of-life care is to be provided. While approximately one-third of patients who pass away in-hospital are reviewed by the rapid response team (RRT), there is limited available research on other factors associated with mortality within the hospital setting.

AIMS

To describe the epidemiology of in-hospital mortality within a tertiary-level hospital, particularly in the context of RRT activation.

METHODS

We utilised the database extraction of demographic, admission and RRT activation data on acute patients discharged from an Australian acute tertiary hospital between 1 January 2009 and 31 December 2013. Analyses included simple descriptors, Chi-squared and non-parametric Kruskal-Wallis tests as appropriate.

RESULTS

Of the 44,297 patients discharged from our hospital, 1603 died during admission. The general medical, haematology/oncology and intensive care teams provided care for the majority of the patients who died. A small number of diagnoses had in-patient mortality rates of greater than 25%. These included respiratory failure, alcoholic liver disease, vascular disorders of the intestine, sepsis and aspiration pneumonia. Over 75% of patients who received a RRT call survived to hospital discharge; however, patients who received four or more RRT calls during admission had an in-hospital mortality rate of over 40%.

CONCLUSION

Acute in-patient mortality is unequally distributed throughout the hospital, and a small number of diagnoses has large associated in-patient mortality rates. Repeated involvement of the RRT is associated with in-patient mortality.

Clinical significance of palliative care assessment in patients referred for urgent intensive care unit admission: A cohort study

PURPOSE

To evaluate clinical characteristics of patients with palliative care (PC) and urgent intensive care unit (ICU) referrals in the same hospital admission.

METHODS

All urgent ICU referrals at an academic, tertiary hospital, and the co-occurrence and timing of PC assessment were retrieved from a prospectively collected database.

RESULTS

From May 2014 to May 2015, 2476 patients were analyzed and 179 (7%) had co-occurrence of PC assessment and urgent ICU referral in the same hospital admission. Hospital mortality was higher (odds ratio, 8.3; 95% confidence interval, 5.4-12.7) and ICU admission was lower (odds ratio, 0.54; 95% confidence interval, 0.40-0.74) in patients with PC assessment, compared with patients without concurrent PC and ICU referrals. Variables associated with PC assessment were older age, diagnosis of cancer, depressed level of consciousness, nonsurgical admission, lower performance status, physician's subjective prognosis of poor outcome, and length of hospitalization before ICU referral.

CONCLUSION

In this cohort of patients with urgent ICU referral, clinical characteristics at the moment of ICU referral were associated with co-occurrence of PC assessment in the same hospital admission. These characteristics might guide the development of instruments to enhance early referral of high-risk patients to PC services.

Do not resuscitate: An expanding role for critical care response team

BACKGROUND

Do not resuscitate (DNR) order is an important aspect of medical practice. Since the implementation of critical care response team (CCRT), frequently we have encountered with patients in the wards that should have been made DNR. Initiating DNR became an important part of CCRT activity. We were obliged to extended the role of CCRT - beyond managing seriously ill patients - in addressing the code status for patients after discussion with the managing teams.

PURPOSE

We compare the trend of initiation of DNR orders in the regular ward before and after implementing CCRT.

METHODS

Our hospital is 1200 bed tertiary care center. CCRT has been launched in January 1, 2008. The CCRT is 24/7 service led by in-house North American certified intensivists. Cohort analysis of prospectively collected data of 5406 CCRT activation from January 1, 2008, to September 30, 2013. Data before implementation of CCRT was available for 299 patients from the period of June 1, 2007, to December 31, 2007. A comparison made between the two groups (before and after implementation of CCRT) for demographic data and percentage of patients in whom DNR order initiated.

RESULTS

Before CCRT implementation, 299 patients were attended by Intensive Care Unit physician for regular consultation, 41.1% were females and 52.4% were males with mean of age 58.44 ± 18.47 standard deviation (SD). DNR was initiated in 2.7% of patients. After CCRT implementation, 5904 CCRT activations, 47.6% females and 52.4% males with mean of age 59.17 ± 20.07 SD DNR initiated in 468 (7.9%) of cases. There was 5.2% increase in DNR orders initiation and completion after CCRT introduced to our institute.

Activities of a Medical Emergency Team: A Prospective Observational Study of 795 Calls

Relatively few papers have examined specific causes for Medical Emergency Team (MET) review and the assessment and management undertaken by the MET. The aim of our study was to describe the type of patients who require MET review, the reasons such reviews are requested and the subsequent immediate management of these patients. Our prospective single-centre observational study was conducted in a university-affiliated tertiary hospital in New Zealand between October 2012 and September 2013. Each trigger for MET review was assessed separately to allow analysis of the main associated underlying conditions and interventions. Seven hundred and ninety-five MET calls were generated for 630 patients. Mean patient age was 64 years. Sixty percent of all calls involved medical patients. There was a marked diurnal variation in the incidence of MET calls, with MET calls more likely during the daytime and evening compared to the night. The most common triggers for MET calls were an unresponsive or fitting patient (25.2%), tachycardia (24.2%), and an Early Warning Score of 8 or more (22.8%). Neurological causes (30.7%), cardiovascular failure (hypotension, pulmonary oedema) (26.7%), respiratory failure (22.6%), and sepsis (19.2%) were the most common underlying conditions. One of these top four conditions was present in nearly all patients (99.2%). The majority of MET calls were made for a relatively small number of underlying conditions and triggers, supporting the concept of ‘MET syndromes’. The pattern of interventions is predictable from the triggering condition. This may guide education and training of ward staff to improve detection of deteriorating patients and prevent or pre-emptively manage causes of such deterioration prior to MET criteria being reached. The association between time of day and crisis recognition suggests the hospital system does not reliably detect deteriorating patients. This questions the adequacy of monitoring of deteriorating patients on hospital wards.

Designing a critical care nurse-led rapid response team using only available resources: 6 years later

Rapid response teams have been introduced to intervene in the care of patients whose condition deteriorates unexpectedly by bringing clinical experts quickly to the patient's bedside. Evidence supporting the need to overcome failure to deliver optimal care in hospitals is robust; whether rapid response teams demonstrate benefit by improving patient safety and reducing the occurrence of adverse events remains controversial. Despite inconsistent evidence regarding the effectiveness of rapid response teams, concerns regarding care and costly consequences of unaddressed deterioration in patients' condition have prompted many hospitals to implement rapid response teams as a patient safety strategy. A cost-neutral structure for a rapid response team led by a nurse from the intensive care unit was implemented with the goal of reducing cardiopulmonary arrests occurring outside the intensive care unit. The results of 6 years' experience indicate that a sustainable and effective rapid response team response can be put into practice without increasing costs or adding positions and can decrease the percentage of cardiopulmonary arrests occurring outside the intensive care unit.

The Goals of Patient Care project: implementing a proactive approach to patient-centred decision-making

BACKGROUND

Patients in the later stages of their lives risk being harmed by futile or unwanted interventions if realistic care goals and patient values are not recognised. Doctors have difficulty discussing and informing patients' healthcare goals.

AIMS

To review implementation of a Goals of Patient Care (GOPC) summary in medical inpatients and its applicability in emergency medical response (EMR) situations.

METHODS

Single-centre cross-sectional study of adult medical inpatients and adult inpatients requiring EMR at a Victorian general hospital.

MEASURES

presence and content of GOPC summary, secondary review of decision-making and discussion documentation, patient characteristics; EMR precipitants and outcomes.

RESULTS

GOPC were documented for 82 of 101 patients. One had an existing advance directive, and six had records of a patient-appointed substitute decision-maker. For patients with GOPC, 80 had life-prolonging treatment aims, with a varying degree of treatment limitation in 48. Discussion with patient or substitute decision-maker was evident in 43 cases. GOPC were documented prior to nine of 23 EMR. The EMR triggered a GOPC modification in three instances.

CONCLUSIONS

Introduction of a routine GOPC summary encourages consideration of goals of care for most medical inpatients. Few have pre-existing records of their wishes, and there are opportunities for improvement in this regard. Doctors may still have difficulty determining goals of care, and discussion of GOPC with patients and families may not be clearly documented. Most patients requiring EMR do not have prior GOPC review, and the role of the summary in these situations remains unclear.

A retrospective cohort study of age-based differences in the care of hospitalized patients with sudden clinical deterioration

PURPOSE

The proportion of elderly patients is increasing, but it is unknown if there are age-based differences in care of hospitalized patients with sudden clinical deterioration. We sought to examine the relation between patient age and care for hospitalized patients experiencing sudden clinical deterioration.

METHODS

We identified hospitalized adults (n = 5103) in 4 hospitals with sudden clinical deteriorations triggering medical emergency team (MET) activation between January 1, 2007, and December 31, 2009. We compared intensive care unit (ICU) admission rates (within 2 hours of MET activation), goals of care (resuscitative vs nonresuscitative), and hospital mortality according to age (<50, 50-64, 65-79, and 80+ years), adjusting for patient, physician, and hospital characteristics.

RESULTS

Age was associated with decreased likelihood of admission to ICU (P < .0001) and increased likelihood of change in goals of care (P < .0001). Compared to patients younger than 50 years, patients 80 years or older had 67% lower odds of ICU admission (odds ratio, 0.33; 95% confidence interval, 0.26-0.41) and 587% higher odds (odds ratio, 6.87; 95% confidence interval, 4.20-11.26) of having their goals of care changed to exclude resuscitation. Hospital mortality was associated with patient age, ranging from 15% to 46% (P < .0001).

CONCLUSIONS

Patient age is associated with care for hospitalized patients with sudden clinical deterioration, suggesting that strategies to guide care of elderly patients during MET activation may be beneficial.

Intensive care unit admission in patients following rapid response team activation: call factors, patient characteristics and hospital outcomes

Rapid Response Systems (RRSs) have been widely introduced throughout hospital health systems, yet there is limited research on the characteristics and outcomes of patients admitted to an intensive care unit (ICU) following RRS activation. Using database extraction, this study examined the factors associated with ICU admission and patient outcome in patients receiving RRS activation in a tertiary level hospital between 2009 and 2013. Of 3004 RRS activations, 392 resulted in ICU admissions. Call factors associated with ICU admission and increased hospital mortality included tachypnoea (P <0.001 and P <0.001, respectively), hypoxia (P <0.001 and P <0.001, respectively) and having multiple Medical Emergency Team call triggers breached simultaneously (P <0.001 and P <0.001, respectively). Patients with seizures (P <0.001) and tachycardia (P=0.004) were more likely to survive to hospital discharge. Patient factors associated with ICU admission included young age (P <0.001) and having severe liver disease (P <0.001). Factors associated with increased hospital mortality included delayed RRS activation (P <0.001), increased age (P <0.001) and comorbidities including ischaemic heart disease (P=0.006), congestive heart failure (P <0.001), chronic kidney disease (P <0.001) and severe liver disease (P <0.001). Multiple factors relating to both the nature of the RRS activation call and patient characteristics are associated with ICU admission and hospital mortality post RRS activation. This information may be useful for risk stratification of deteriorating patients and determination of appropriate escalation.

Hospital rapid response team and patients with life-limiting illness: a multicentre retrospective cohort study

BACKGROUND

Approximately one-third of rapid response team consultations involve issues of end-of-life care. We postulate a greater occurrence in patients with a life-limiting illness, in whom the opportunity for advance care planning and palliative care involvement should be offered.

AIMS

We aim to review the characteristics and compare outcomes of rapid response team consultations on patients with and without a life-limiting illness.

DESIGN/SETTING

A 3-month retrospective cohort study of all rapid response team consultations was conducted. The sample population included all adult inpatients in a major teaching hospital network.

RESULTS

We identified 351 patients - including 139 with a life-limiting illness - receiving a total of 456 rapid response team consultations. The median time from admission to the first rapid response team consultation was 3 days. Patients with a life-limiting illness had a significantly higher mortality rate (41.7% vs 13.2%), were older (72.6 vs 63.5 years), more likely to come from a residential aged-care facility (29.5% vs 4.1%) and had a shorter hospital stay (10 vs 13 days). Rapid response team consultations resulted in a change to more palliative goals of care in 28.5% of patients, of whom two-thirds had a life-limiting illness.

CONCLUSION

Patients with a life-limiting illness had worse outcomes post-rapid response team consultation. Our findings suggest that a routine clarification of goals of care for this cohort, within 3 days of hospital admission, may be advantageous. These discussions may provide clarity of purpose to treating teams, reduce the burden of unnecessary interventions and promote patient-centred care agreed upon in advance of any deterioration.

Development of a tool for defining and identifying the dying patient in hospital: Criteria for Screening and Triaging to Appropriate aLternative care (CriSTAL)

OBJECTIVE

To develop a screening tool to identify elderly patients at the end of life and quantify the risk of death in hospital or soon after discharge for to minimise prognostic uncertainty and avoid potentially harmful and futile treatments.

DESIGN

Narrative literature review of definitions, tools and measurements that could be combined into a screening tool based on routinely available or obtainable data at the point of care to identify elderly patients who are unavoidably dying at the time of admission or at risk of dying during hospitalisation.

MAIN MEASUREMENTS

Variables and thresholds proposed for the Criteria for Screening and Triaging to Appropriate aLternative care (CriSTAL screening tool) were adopted from existing scales and published research findings showing association with either in-hospital, 30-day or 3-month mortality.

RESULTS

Eighteen predictor instruments and their variants were examined. The final items for the new CriSTAL screening tool included: age ≥65; meeting ≥2 deterioration criteria; an index of frailty with ≥2 criteria; early warning score >4; presence of ≥1 selected comorbidities; nursing home placement; evidence of cognitive impairment; prior emergency hospitalisation or intensive care unit readmission in the past year; abnormal ECG; and proteinuria.

CONCLUSIONS

An unambiguous checklist may assist clinicians in reducing uncertainty patients who are likely to die within the next 3 months and help initiate transparent conversations with families and patients about end-of-life care. Retrospective chart review and prospective validation will be undertaken to optimise the number of prognostic items for easy administration and enhanced generalisability. Development of an evidence-based tool for defining and identifying the dying patient in hospital: CriSTAL.

Integration of palliative care in the context of rapid response: a report from the Improving Palliative Care in the ICU advisory board

Rapid response teams (RRTs) can effectively foster discussions about appropriate goals of care and address other emergent palliative care needs of patients and families facing life-threatening illness on hospital wards. In this article, The Improving Palliative Care in the ICU (IPAL-ICU) Project brings together interdisciplinary expertise and existing data to address the following: special challenges for providing palliative care in the rapid response setting, knowledge and skills needed by RRTs for delivery of high-quality palliative care, and strategies for improving the integration of palliative care with rapid response critical care. We discuss key components of communication with patients, families, and primary clinicians to develop a goal-directed treatment approach during a rapid response event. We also highlight the need for RRT expertise to initiate symptom relief. Strategies including specific clinician training and system initiatives are then recommended for RRT care improvement. We conclude by suggesting that as evaluation of their impact on other outcomes continues, performance by RRTs in meeting palliative care needs of patients and families should also be measured and improved.

The effect of rapid response teams on end-of-life care: a retrospective chart review

BACKGROUND

A subset of critically ill patients have end-of-life (EOL) goals that are unclear. Rapid response teams (RRTs) may aid in the identification of these patients and the delivery of their EOL care.

OBJECTIVES

To characterize the impact of RRT discussion on EOL care, and to examine how a preprinted order (PPO) set for EOL care influenced EOL discussions and outcomes.

METHODS

A single-centre retrospective chart review of all RRT calls (January 2009 to December 2010) was performed. The effect of RRT EOL discussions and the effect of a hospital-wide PPO set on EOL care was examined. Charts were from the Ontario Ministry of Health and Long-Term Care Critical Care Information Systemic database, and were interrogated by two reviewers.

RESULTS

In patients whose EOL status changed following RRT EOL discussion, there were fewer intensive care unit (ICU) transfers (8.4% versus 17%; P<0.001), decreased ICU length of stay (5.8 days versus 20 days; P=0.08), increased palliative care consultations (34% versus 5.3%; P<0.001) and an increased proportion who died within 24 h of consultation (25% versus 8.3%; P<0.001). More patients experienced a change in EOL status following the introduction of an EOL PPO, from 20% (before) to 31% (after) (P<0.05).

CONCLUSIONS

A change in EOL status following RRT-led EOL discussion was associated with reduced ICU transfers and enhanced access to palliative care services. Further study is required to identify and deconstruct barriers impairing timely and appropriate EOL discussions.

Noncomfort medication use in acute care inpatients comanaged by palliative care specialists near the end of life: a cohort study

BACKGROUND/OBJECTIVE

To examine comfort medication (CM) and noncomfort (NC) medication use in inpatients comanaged by palliative care (PC) near the end of life.

METHODS

Chart review of inpatients comanaged by the PC service at 2 academic hospitals. Medications were categorized as CM and NC medication according to the published guidelines.

RESULTS

Seventy patients met inclusion criteria. In the final week of life, inpatients were receiving a mean of 6 CM (40 doses) and 7 NC medications (41 doses). Four new NC medications were started per patient, but only 3 were discontinued. The NC medications were most frequently discontinued on the day of PC consult, but 14% were stopped on the day of death/PC unit transfer.

CONCLUSION

Inpatients comanaged by PC continue to receive NC medications as they near the end of life.
