Avoiding adult in-hospital cardiac arrest: A retrospective cohort study to determine preventability

Rapid Response Systems

The hospital rapid response system (RRS) is a patient safety and quality intervention that responds quickly to clinical deteriorations on general wards with the goal of preventing cardiopulmonary arrests, reducing hospital mortality, and facilitating triage and level of care escalations. The RRS is one of the first organized, and systematic, elements of the "ICU without walls" model. RRSs have been shown to be effective in preventing deterioration to cardiopulmonary arrest on general hospital wards and reducing total and unexpected hospital mortality. Recent studies have demonstrated that this benefit can be enhanced through targeted improvements and modifications of existing RRSs.

A novel structured debriefing program for consensus determinations of in-hospital cardiac arrest predictability and preventability

AIM

Hospital rapid response systems aim to stop preventable cardiac arrests, but defining preventability is a challenge. We developed a multidisciplinary consensus-based process to determine in-hospital cardiac arrest (IHCA) preventability based on objective measures.

METHODS

We developed an interdisciplinary ward IHCA debriefing program at an urban quaternary-care academic hospital. This group systematically reviewed all IHCAs weekly, reaching consensus determinations of the IHCA's cause and preventability across three mutually exclusive categories: 1) unpredictable (no evidence of physiologic instability < 1 h prior to and within 24 h of the arrest), 2) predictable but unpreventable (meeting physiologic instability criteria in the setting of either a poor baseline prognosis or a documented goals of care conversation) or 3) potentially preventable (remaining cases).

RESULTS

Of 544 arrests between 09/2015 and 11/2023, 339 (61%) were deemed predictable by consensus, with 235 (42% of all IHCAs) considered potentially preventable. Potentially preventable arrests disproportionately occurred on nights and weekends (70% vs 55%, p = 0.002) and were more frequently respiratory than cardiac in etiology (33% vs 15%, p < 0.001). Despite similar rates of ROSC across groups (67-70%), survival to discharge was highest in arrests deemed unpredictable (31%), followed by potentially preventable (21%), and then those deemed predictable but unpreventable which had the lowest survival rate (16%, p = 0.007).

CONCLUSIONS

Our IHCA debriefing procedures are a feasible and sustainable means of determining the predictability and potential preventability of ward cardiac arrests. This approach may be useful for improving quality benchmarks and care processes around pre-arrest clinical activities.

Non-beneficial resuscitation during in-hospital cardiac arrests in a metropolitan teaching hospital

PURPOSE

To describe the prevalence of non-beneficial resuscitation attempts in hospitalised patients and identify interventions that could be used to reduce these events.

METHODS

A retrospective analysis was conducted of all adult IHCAs receiving cardiopulmonary resuscitation (CPR) in a teaching hospital over nine years. Demographics and arrest characteristics were obtained from a prospectively collected database. Non-beneficial CPR was defined as CPR being administered to patients who had a current not for resuscitation (NFR) order in place or who had an NFR order enacted on a previous hospital admission. Further antecedent factors and resuscitation characteristics were collected for these patients.

RESULTS

There were 257 IHCAs, of which 115 (44.7%) occurred on general wards, with 19.8% of all patients surviving to discharge home. There were 39 (15.2%) instances of non-beneficial CPR of which 28/39 (72%) occurred in unmonitored patients on the ward comprising nearly a quarter (28/115) of all arrests in this patient group. A specialist had reviewed 30/39 (76.9%) of these patients, and 33.3% (13/39) had a medical emergency team (MET) review prior to their arrest.

CONCLUSIONS

Over one in seven resuscitation attempts were non-beneficial. MET reviews and specialist ward rounds provide opportunities to improve the documentation and visibility of NFR status. This article is protected by copyright. All rights reserved.

eStablish And Formalize Expert Criteria for Avoidable Resuscitation Review (SAFECARR) Electronic Delphi: Development of a Consensus Framework for Classifying and Reviewing Cardiac Arrests Within the PICU

OBJECTIVES

To develop a consensus framework that can guide the process of classifying and reviewing pediatric in-hospital cardiac arrest in the PICU.

DESIGN

A three-round electronic Delphi consensus study with an additional in-person session with pediatric resuscitation experts. The modified electronic Delphi consisted of survey questions sent to the expert panel with the goals of (1) achieving consensus on definitions of avoidable, potentially avoidable, and unavoidable PICU in-hospital cardiac arrest and (2) achieving consensus and ranking of a list of factors that contribute to potentially avoidable PICU in-hospital cardiac arrest.

SETTING

Electronic surveys of resuscitation experts including pediatric critical care, cardiac critical care, emergency medicine, and hospital medicine physicians, nurses, advance practice nurses, and resuscitation researchers.

PATIENTS

Not applicable.

INTERVENTIONS

Not applicable.

MEASUREMENTS AND MAIN RESULTS

Over three rounds of an electronic Delphi, 24 resuscitation experts participated. In Round 1, consensus was reached for the definitions of potentially avoidable and unavoidable cardiac arrest. Consensus was not reached for avoidable cardiac arrest. In Round 2, the expert panel agreed with seven factors from the literature and achieved consensus on an additional seven factors. Consensus was achieved on the modified definition of avoidable cardiac arrest. In Round 3, participants were asked to rank the contributing factors in order of their importance. For the in-person session, the consensus definitions and contributing factors from the modified electronic Delphi were presented to a multidisciplinary group of pediatric resuscitation experts and reached consensus for all three definitions.

CONCLUSIONS

A multidisciplinary group of pediatric resuscitation experts generated a consensus-based framework to classify and review pediatric in-hospital cardiac arrest in the PICU. Future work will focus on the application of this framework and further validation of these definitions and contributing factors for in-hospital cardiac arrest both within and outside the PICU.

Improving sepsis care for hospital inpatients using existing medical emergency response systems

BACKGROUND

Sepsis is a medical emergency; timely management has been shown to reduce mortality. We aimed to improve the care of inpatients who developed sepsis after hospital admission by integrating a sepsis bundle with an existing medical emergency team (MET).

METHODS

We performed a before-and-after study at an Australian institution. A multimodal intervention was implemented including formation of a working group, development of a guideline, standard documentation, education, audit and feedback. The primary outcome was the proportion of MET calls where there was compliance with the sepsis resuscitation bundle within one hour of MET call.

RESULTS

There was an improvement in completion of the entire resuscitation bundle (OR 2.33, 95%, CI: 1.23 - 4.41) and lactate measurement (OR 2.72, CI: 1.53, 4.84) within one hour of MET call. There was a non-significant reduction in the median time to antibiotic administration in patients where antibiotics were initiated or changed at the MET call (60 mins vs. 44 mins, p = 0.8). In hospital mortality was observed to fall from 22.1% to 11.4%, but after adjusting for age and baseline illness severity this differences was not statistically significant (OR 0.52, CI: 0.23, 1.19, p = 0.12).

CONCLUSION

The implementation of a multimodal sepsis bundle and the utilisation of an existing MET call system demonstrated an increase in the overall uptake of a sepsis bundle. This was associated with an observed reduction in all-cause in-hospital mortality, although this difference was not statistically significant after adjustment for confounders. Further interventions with a focus on nursing education and engagement may improve timely antibiotic administration.

A review of Code Blue activations in a single Regional Australian Healthcare Service: A retrospective descriptive study of RISKMAN data

BACKGROUND

In the case of life-threatening conditions such as respiratory or cardiac arrest, or the clinical deterioration of the patient, a Code Blue activation may be instigated. A Code Blue activation involves a team of advanced trained clinicians attending the emergency needs of the patient.

AIMS AND OBJECTIVES

The aim of the study was to explore the number of cases of Code Blue activations, looking at the timing, clinical ward, diagnosis and activation criteria while noting cases where escalation from a Medical Emergency Team (MET) call occurs in one Regional Healthcare Service in Victoria, Australia, over a six-year period.

METHODS

A quantitative retrospective descriptive study of Code Blue emergencies over a six-year period from June 2010 to June 2016 was conducted. Data collected from the RISKMAN program operating at a single site was imported into SPSS (V 22) for descriptive statistical analysis. A STROBE EQUATOR checklist was used for this study (see File S1).

FINDINGS

The majority of Code Blue activations were male (59%, n = 127) and aged between 70 and 89 years of age (43%, n = 93). A Code Blue activation was more likely to occur at 08:00 hr, 14:00 hr or 22:00 hr, corresponding to the nurses' change in shift, with the majority of Code Blues (27.8%, n = 60) occurring in the emergency department. Cardiac arrest was the main activation criterion with 54.6% (n = 118) cases followed by respiratory arrest (14%, n = 32). Interestingly, 20% (n = 45) of the Code Blue activations were upgraded from a Medical Emergency Team (MET) call.

CONCLUSION

This project has produced several interesting findings surrounding Code Blue activations at one regional healthcare service which are not present in existing literature and is worthwhile for further investigation.

RELEVANCE TO CLINICAL PRACTICE

Understanding Code Blue activation criteria, common timings (month, time of day) and patient demographics ensures clinicians can remain vigilant in watching for the signs of patient deterioration and improve staff preparedness Code Blue events.

To identify the factors that influence the recognizing and responding to adult patient deterioration in acute hospitals

AIMS

To identify factors that influence recognition and response to adult patient deterioration in acute hospitals.

DESIGN

A mixed-studies systematic review.

DATA SOURCES

CINAHL, Medline, and Web of Science were searched for relevant literature published between 2007 - 2018.

REVIEW METHODS

Studies were critically appraised, data extracted and thematically analysed.

RESULTS

Thirteen papers met the inclusion criteria. Three main themes were identified: (a) Knowledge and understanding of clinical deterioration; (b) Organizational factors; managing deterioration and staffing levels; and (c) Communication; inter-professional relationships and professional-patient communication.

CONCLUSION

Despite national guidelines, the review findings suggest that the recognition and response to adult patient deterioration in acute hospital settings is sub-optimal. A multitude of factors influencing the recognition and response to adult patient deterioration emerged from the findings.

IMPACT

Patients are receiving sub-optimal care due to failure in recognizing and responding to patient deterioration in an appropriate and timely manner. Nurses lack knowledge and understanding of deterioration. Organizational factors contribute to inadequate care and communication among professionals was highlighted as challenging. The factors that influence the recognizing and responding to patient deterioration in acute hospitals are multi-faceted, however this review highlights immediate recommendations for professionals in the acute care setting.
