The influence of the probability of survival on patients' preferences regarding cardiopulmonary resuscitation

Aligning patient values and code status: Choice of Diction's Effect (CODE) study

BACKGROUND

Decisions regarding resuscitation after cardiac arrest are critical from ethical, patient satisfaction, outcome, and healthcare cost standpoints. Physician-reported discussion barriers include topic discomfort, fear of time commitment, and difficulty articulating end-of-life concepts. The influence of language used in these discussions has not been tested. This study explored whether utilizing the alternate term "allow (a) natural death" changed code status decisions in hospitalized patients versus "do not resuscitate" (DNR).

METHODS

All patients age 65 and over admitted to a general medicine hospital teaching service were screened (English-speaking, not ICU-level care, no active psychiatric illness, no substance misuse, no active DNR). Participants were randomized to resuscitation discussions with either DNR or "allow natural death" as the "no code" phrasing. Outcomes included patient resuscitation decision, satisfaction with and duration of the conversation, and decision correlation with illness severity and predicted resuscitation success.

RESULTS

102 participants were randomized to the "allow natural death" (N = 49) or DNR (N = 53) arms. The overall "no code" rate for our sample of hospitalized general medicine inpatients age >65 was 16.7%, with 13% in the DNR and 20.4% in the "allow natural death" arms (p = 0.35). Discussion length was similar in the DNR and "allow natural death" arms (3.9 + 3.2 vs. 4.9 + 3.9 minutes), and not significantly different (p = 0.53). Over 90% of participants were highly satisfied with their code status decision, without difference between arms (p = 0.49).

CONCLUSIONS

Participants' code status discussions did not differ in "no code" rate between "allow natural death" and DNR arms but were short in length and had high patient satisfaction. Previously reported code status discussion barriers were not encountered. It is appropriate to screen code status in all hospitalized patients regardless of phrasing used.

Top 5 barriers in cardiac arrest research as perceived by international early career researchers - A consensus study

Aim of the study

Cardiac arrest research has not received as much scientific attention as research on other topics. Here, we aimed to identify cardiac arrest research barriers from the perspective of an international group of early career researchers.

Methods

Attendees of the 2022 international masterclass on cardiac arrest registry research accompanied the Global Out-of-Hospital Cardiac Arrest Registry collaborative meeting in Utstein, Norway, and used an adapted hybrid nominal group technique to obtain a diverse and comprehensive perspective. Barriers were identified using a web-based questionnaire and discussed and ranked during an in-person follow-up meeting. After each response was discussed and clarified, barriers were categorized and ranked over two rounds. Each participant scored these from 1 (least significant) to 5 (most significant).

Results

Nine participants generated 36 responses, forming seven overall categories of cardiac arrest research barriers. "Allocated research time" was ranked first in both rounds. "Scientific environment", including appropriate mentorship and support systems, ranked second in the final ranking. "Resources", including funding and infrastructure, ranked third. "Access to and availability of cardiac arrest research data" was the fourth-ranked barrier. This included data from the cardiac arrest registries, medical devices, and clinical studies. Finally, "uniqueness" was the fifth-ranked barrier. This included ethical issues, patient recruitment challenges, and unique characteristics of cardiac arrest.

Conclusion

By identifying cardiac arrest research barriers and suggesting solutions, this study may act as a tool for stakeholders to focus on helping early career researchers overcome these barriers, thus paving the road for future research.

Overestimation of Survival Rates of Cardiopulmonary Resuscitation Is Associated with Higher Preferences to Be Resuscitated: Evidence from a National Survey of Older Adults in Switzerland

BACKGROUND

Many widely used advance directives templates include direct questions on individuals' preferences for cardiopulmonary resuscitation (CPR) in case of decision-making incapacity during medical emergencies. However, as knowledge of the survival rates of CPR is often limited, individuals' advance decisions on CPR may be poorly aligned with their preferences if false beliefs about the survival rates of CPR shape stated preferences for CPR.

METHODS

We analyzed nationally representative data from 1,469 adults aged 58+ y who responded to wave 8 (2019/2020) of the Swiss version of the Survey on Health, Ageing, and Retirement in Europe (SHARE) to assess the partial association between knowledge of CPR survival rates and stated preferences for CPR using multivariable probit regression models that adjust for social, health, and regional characteristics. Knowledge of CPR survival rates was assessed by asking how likely it is in general in Switzerland for a 70-y-old to survive until hospital discharge from a CPR performed outside of a hospital. Preferences for CPR were measured by asking respondents if they would wish to be resuscitated in case of cardiac arrest.

RESULTS

Only 9.3% of respondents correctly assessed the chances for a 70-y-old to survive until hospital discharge from a CPR performed outside of a hospital, while 65.2% indicated a preference to be resuscitated in case of a cardiac arrest. Respondents who correctly assessed CPR survival were significantly more likely to wish not to be resuscitated (average marginal effect: 0.18, P < 0.001).

CONCLUSIONS

Reducing misconceptions concerning the survival rates of CPR could change older adults' preferences for CPR and make them more likely to forgo such treatments.

HIGHLIGHTS

Many older adults in Switzerland overestimate the survival rates of cardiopulmonary resuscitation (CPR).The study reveals that individuals with accurate knowledge of CPR survival rates are more likely to refuse resuscitation in case of cardiac arrest.Overestimation of CPR survival rates may lead to a mismatch between individuals' preferences for CPR and their actual end-of-life care decisions.Improving the general population's knowledge of CPR survival rates is crucial to ensure informed decision making and effective advance care planning.

The trajectory of very old critically ill patients

The demographic shift, together with financial constraint, justify a re-evaluation of the trajectory of care of very old critically ill patients (VIP), defined as older than 80 years. We must avoid over- as well as under-utilisation of critical care interventions in this patient group and ensure the inclusion of health care professionals, the patient and their caregivers in the decision process. This new integrative approach mobilises expertise at each step of the process beginning prior to intensive care unit (ICU) admission and extending to long-term follow-up. In this review, several international experts have contributed to provide recommendations that can be universally applied. Our aim is to define a minimum core dataset of information to be shared and discussed prior to ICU admission and to facilitate the shared-decision-making process with the patient and their caregivers, throughout the patient journey. Documentation of uncertainty may contribute to a tailored level of care and ultimately to discussions around possible limitations of life sustaining treatments. The goal of ICU care is not only to avoid death, but more importantly to maintain an acceptable quality of life and functional autonomy after hospital discharge. Societal consideration is important to highlight, together with alternatives to ICU admission. We discuss challenges for the future and potential areas of research. In summary, this review provides a state-of-the-art current overview and aims to outline future directions to address the challenges in the treatment of VIP.

[Opportunities and risks of advance directives : An appraisal of the practice in Germany after legal regulation in 2009]

BACKGROUND

Living wills/advance directives (AD) are an important tool for specifying patient wishes regarding medical care in the case of future inability to consent. Since 2009, German legislation defines framework conditions for the creation and validity of such directives in § 1901a BGB.

METHODS

An extensive literature search in an international and a German-language database was conducted to identify, analyze, and evaluate scientific articles on opportunities, risks, and problems in the creation and implementation of living wills.

RESULTS

Between 10 and 40% of patients have an AD. Among the stipulations in the AD, the demand for sufficient pain therapy is very important. However, numerous problems in the preparation and implementation of ADs reduce their value in everyday clinical practice. In particular, unclear conditions of validity, unspecific instructions for action, and lack of availability of the directives prevent practitioners from determining the patient's will. Other fundamental problems include frequent patient ambivalence and clinical ethical dissent. In addition, the framework condition of unlimited coverage set by the law carries the risk that changes of opinion in the course of life or disease are not taken into account.

CONCLUSION

Preparing an AD requires a high level of information, consultation, and time, as well as regular review or adjustment of its content. These factors are often not considered, thus complicating implementation and reducing the value of living wills. Possible solutions to these problems or alternative concepts for different patient settings are discussed in this review.

Trend of Outcome Metrics in Recent Out-of-Hospital-Cardiac-Arrest Research: A Narrative Review of Clinical Trials

Cardiopulmonary resuscitation (CPR) research traditionally focuses on survival. In 2018, the International Liaison Committee on Resuscitation (ILCOR) proposed more patient-centered outcomes. Our narrative review assessed clinical trials after 2018 to identify the trends of outcome metrics in the field OHCA research. We performed a search of the PubMed database from 1 January 2019 to 22 September 2023. Prospective clinical trials involving adult humans were eligible. Studies that did not report any patient-related outcomes or were not available in full-text or English language were excluded. The articles were assessed for demographic information and primary and secondary outcomes. We included 89 studies for analysis. For the primary outcome, 31 (35%) studies assessed neurocognitive functions, and 27 (30%) used survival. For secondary outcomes, neurocognitive function was present in 20 (22%) studies, and survival was present in 10 (11%) studies. Twenty-six (29%) studies used both survival and neurocognitive function. Since the publication of the COSCA guidelines in 2018, there has been an increased focus on neurologic outcomes. Although survival outcomes are used frequently, we observed a trend toward fewer studies with ROSC as a primary outcome. There were no quality-of-life assessments, suggesting a need for more studies with patient-centered outcomes that can inform the guidelines for cardiac-arrest management.

Older adults' medical preferences for the end of life: a cross-sectional population-based survey in Switzerland

OBJECTIVES

Medical decision-making at the end of life is common and should be as patient-centred as possible. Our study investigates older adults' preferences towards three medical treatments that are frequently included in advance directive forms and their association with social, regional and health characteristics.

SETTING

A cross-sectional study using population-based data of wave 8 (2019/2020) of the Swiss component of the Survey of Health, Ageing and Retirement in Europe.

PARTICIPANTS

1430 adults aged 58 years and older living in Switzerland.

PRIMARY AND SECONDARY OUTCOME MEASURES

Three questions on the preferences regarding cardiopulmonary resuscitation (CPR); life-prolonging treatment in case of high risk of permanent mental incapacity; reduced awareness (sedation) to relieve unbearable pain and symptoms. Their associations with individuals' social, regional and health characteristics.

RESULTS

Most older adults expressed a wish to receive CPR (58.6%) and to forgo life-prolonging treatment in case of permanent mental incapacity (92.2%). Most older adults also indicated that they would accept reduced awareness if necessary to receive effective treatment for pain and distressing symptoms (59.2%). Older adults' treatment preferences for CPR and life-prolonging treatment differed according to sex, age, partnership status, linguistic region and health status, while willingness to accept reduced awareness for effective symptom treatment was more similarly distributed across population groups.

CONCLUSIONS

Simultaneous preferences for CPR and refusal of life-prolonging treatment might appear to be conflicting treatment goals. Considering individuals' values and motivations can help clarify ambivalent treatment decisions. Structured advance care planning processes with trained professionals allows for exploring individuals' motivations and values and helps to identify congruent care and treatment goals.

"If I Become a Vegetable, Then no": A Thematic Analysis of How Patients and Physicians Refer to Prognosis When Discussing Cardiopulmonary Resuscitation

Background: Documenting decisions about the relevance cardiopulmonary resuscitation (CPR) is a standard practice at hospital admission yet a complex task. Objective: Our aim was to explore how physicians approach and discuss CPR prognosis with older patients recently admitted to a post-acute care unit. Method: We recorded 43 conversations between physicians and patients about the relevancy of CPR that took place at admission at the geriatric rehabilitation service of a Swiss university hospital. Thematic analysis determined (i) who initiated the talk about CPR prognosis, (ii) at what point in the conversation, and (iii) how prognosis was referred to. Results: Prognosis was mentioned in 65% of the conversations. We categorized the content of references to CPR prognosis in five themes: factors determining the prognosis (general health, age, duration of maneuvers); life (association of CPR with life, survival); proximal adverse outcomes (broken ribs, intensive care); long-term adverse outcomes (loss of autonomy, suffering a stroke, pain, generic, uncertainty); and being a burden. Discussion and conclusion: Discussing CPR is important to all patients, including those for whom it is not recommended. Information about CPR prognosis is essential to empower and support patients in expressing their expectations from life-prolonging interventions and attain shared decision-making.

Perceptions and Knowledge Regarding Medical Situations at the End of Life among Older Adults in Switzerland

Background: Perceptions and knowledge regarding end-of-life health and health care can influence individuals' advance care planning, such as the completion and content of advance directives. Objectives: To assess older adults' perceptions of medical end-of-life situations in Switzerland along with their accuracy and corresponding associations with sociodemographic characteristics. Design: This is an observational study. Setting/study subjects: A nationally representative sample of adults aged 58 years and older who participated in wave 8 (2019/2020) of the Swiss part of the Survey of Health, Ageing, and Retirement in Europe (cooperation rate: 94.3%). Measurements: Subjective likelihood of 11 end-of-life situations on a 4-point scale: very unlikely (0-25%), rather unlikely (26%-50%), rather likely (51%-75%), and very likely (76%-100%). Results: Older adults' perceptions of end-of-life medical situations in Switzerland were rather heterogeneous and often inaccurate. Study subjects overestimated the success of cardiopulmonary resuscitation, the utility of a fourth-line chemotherapy, of hospital admission for pneumonia for patients with advanced dementia, and for artificial nutrition and hydration in the dying phase, while underestimating the effectiveness of pain management in this situation. Less than 28% of older adults correctly assessed the likelihood of dying in a nursing home, hospital, or at home, respectively. Inaccurate views were more frequent in men (p < 0.01) and individuals with financial difficulties (p < 0.05), whereas adults aged 75+ years (p < 0.01) and respondents from the German-speaking part of Switzerland (p < 0.01) had more accurate perceptions. Conclusions: The wide variation and low accuracy of end-of-life perceptions suggest considerable scope for communication interventions about the reality of end-of-life health and health care in Switzerland.

Frailty and Survival After In-Hospital Cardiopulmonary Resuscitation

BACKGROUND

Older adults face high mortality following resuscitation efforts for in-hospital cardiac arrest. Less is known about the role of frailty in survival to discharge after in-hospital cardiopulmonary resuscitation.

OBJECTIVE

To investigate whether frailty, measured by the Clinical Frailty Scale, is associated with mortality after cardiopulmonary resuscitation following in-hospital cardiac arrest in older adults in the USA.

DESIGN

Retrospective cohort study.

PARTICIPANTS

Patients ≥ 65 years who had undergone cardiopulmonary resuscitation during an inpatient admission at two urban academic hospitals and three suburban community hospitals within a Boston area healthcare system from January 2018-January 2020. Patients with Clinical Frailty Scale scores 1-3 were considered not frail, 4-6 were considered very mildly, mildly, and moderately frail, respectively, and 7-9 were considered severely frail.

MAIN MEASURES

In-hospital mortality after cardiopulmonary resuscitation.

KEY RESULTS

Among 324 patients who underwent cardiopulmonary resuscitation following in-hospital cardiac arrest, 73.1% experienced in-hospital mortality. Patients with a Clinical Frailty Scale score of 1-3 had 54% in-hospital mortality, which increased to 66%, 78%, 84%, and 84% for those with a Clinical Frailty Scale score of 4, 5, 6, and 7-9, respectively (p = 0.001). After adjusting for age, sex, race, and Charlson Comorbidity Index, higher frailty scores were significantly associated with higher odds of in-hospital mortality. Compared to those with a Clinical Frailty Scale score of 1-3, odds ratios (95% CI) for in-hospital mortality for patients with a Clinical Frailty Scale score of 4, 5, 6, and 7-9 were 1.6 (0.8-3.3), 3.0 (1.3-7.1), 4.4 (1.9-9.9), and 4.6 (1.8-11.8), respectively (p = 0.001).

CONCLUSIONS

Higher levels of frailty are associated with increased mortality after in-hospital cardiopulmonary resuscitation in older adults. Clinicians may consider using the Clinical Frailty Scale to help guide goals of care conversations, including discussion of code status, in this patient population.

Seriously Ill Patients' Prioritized Goals and Their Clinicians' Perceptions of Those Goals

CONTEXT

Seriously ill patients whose prioritized healthcare goals are understood by their clinicians are likely better positioned to receive goal-concordant care.

OBJECTIVES

To examine the proportion of seriously ill patients whose prioritized healthcare goal is accurately perceived by their clinician and identify factors associated with accurate perception.

METHODS

Secondary analysis of a multicenter cluster-randomized trial of outpatients with serious illness and their clinicians. Approximately two weeks after a clinic visit, patients reported their current prioritized healthcare goal- extending life over relief of pain and discomfort, or relief of pain and discomfort over extending life - and clinicians reported their perception of their patients' current prioritized healthcare goal; matching these items defined accurate perception.

RESULTS

Of 252 patients with a prioritized healthcare goal, 60% had their goal accurately perceived by their clinician, 27% were cared for by clinicians who perceived prioritization of the alternative goal, and 13% had their clinician answer unsure. Patients who were older (OR 1.03 per year; 95%CI 1.01, 1.05), had stable goals (OR 2.52; 95%CI 1.26, 5.05), and had a recent goals-of-care discussion (OR 1.78, 95%CI 1.00, 3.16) were more likely to have their goals accurately perceived.

CONCLUSION

A majority of seriously ill outpatients are cared for by clinicians who accurately perceive their patients' prioritized healthcare goals. However, a substantial portion are not and may be at higher risk for goal-discordant care. Interventions that facilitate goals-of-care discussions may help align care with goals, as recent discussions were associated with accurate perceptions of patients' prioritized goals.

Outcomes in adults living with frailty receiving cardiopulmonary resuscitation: A systematic review and meta-analysis

Background

Frailty is a clinical expression of adverse ageing which could be a valuable predictor of outcomes from cardiac arrest. The aim of this systematic review was to evaluate survival outcomes in adults living with frailty versus adults living without frailty receiving cardiopulmonary resuscitation (CPR) following cardiac arrest.

Methods

A comprehensive search of MEDLINE, EMBASE, CINAHL, and Web of Science databases was performed using pre-defined search terms, with no date or language restrictions applied. Prospective and retrospective observational studies measuring outcomes from CPR in adults assessed for frailty using an accepted clinical definition were selected.

Results

Eight eligible studies were included. Seven retrospective observational studies presenting high methodological quality were included in a meta-analysis comprising 1704 participants. Frailty was strongly associated with an increased likelihood of mortality after CPR, with moderate inter-study heterogeneity (OR = 3.56, 95% CI = 2.74–4.63, I² = 71%).

Discussion

This review supports the consideration of frailty status in a holistic approach to CPR. The present findings suggest that frailty status provides valuable prognostic information and could complement other known pre-arrest prognostic factors such as comorbidities in the context of Do Not Attempt CPR consideration. Awareness of the poorer outcomes in those living with frailty could support the identification of individuals less likely to benefit from CPR. Validation of our findings and evaluation of quality-of-life in frail individuals surviving cardiac arrest are prerequisites for the future integration of frailty status into CPR clinical decision-making.

Knowledge Gaps in End-of-Life Care and Planning Options Among Older Adults in Switzerland

Objectives: Good knowledge about end-of-life (EOL) care options helps in discussing and planning important aspects of the end of life in advance and contributes to improved well-being among dying patients and their families.

Methods: Our study explores knowledge levels of EOL care and planning options and its sociodemographic and regional patterning using nationally representative data from respondents aged 55+ of wave 6 of the Survey of Health, Ageing and Retirement in Europe in Switzerland (n = 2,199).

Results: Respondents answered correctly on average to just under four out of eight questions regarding EOL care options. Women, individuals with higher education levels, and those living with a partner showed a higher EOL knowledge score, whereas the score is lower among older adults (75+) and individuals living in French- and Italian-speaking Switzerland.

Conclusion: In view of the significant EOL knowledge gaps among older adults in Switzerland, further education efforts on EOL care options are needed, with particular attention to the population groups most affected.

To explain or not to explain?-Artificial intelligence explainability in clinical decision support systems

Explainability for artificial intelligence (AI) in medicine is a hotly debated topic. Our paper presents a review of the key arguments in favor and against explainability for AI-powered Clinical Decision Support System (CDSS) applied to a concrete use case, namely an AI-powered CDSS currently used in the emergency call setting to identify patients with life-threatening cardiac arrest. More specifically, we performed a normative analysis using socio-technical scenarios to provide a nuanced account of the role of explainability for CDSSs for the concrete use case, allowing for abstractions to a more general level. Our analysis focused on three layers: technical considerations, human factors, and the designated system role in decision-making. Our findings suggest that whether explainability can provide added value to CDSS depends on several key questions: technical feasibility, the level of validation in case of explainable algorithms, the characteristics of the context in which the system is implemented, the designated role in the decision-making process, and the key user group(s). Thus, each CDSS will require an individualized assessment of explainability needs and we provide an example of how such an assessment could look like in practice.

On Assessing Trustworthy AI in Healthcare. Machine Learning as a Supportive Tool to Recognize Cardiac Arrest in Emergency Calls

Artificial Intelligence (AI) has the potential to greatly improve the delivery of healthcare and other services that advance population health and wellbeing. However, the use of AI in healthcare also brings potential risks that may cause unintended harm. To guide future developments in AI, the High-Level Expert Group on AI set up by the European Commission (EC), recently published ethics guidelines for what it terms “trustworthy” AI. These guidelines are aimed at a variety of stakeholders, especially guiding practitioners toward more ethical and more robust applications of AI. In line with efforts of the EC, AI ethics scholarship focuses increasingly on converting abstract principles into actionable recommendations. However, the interpretation, relevance, and implementation of trustworthy AI depend on the domain and the context in which the AI system is used. The main contribution of this paper is to demonstrate how to use the general AI HLEG trustworthy AI guidelines in practice in the healthcare domain. To this end, we present a best practice of assessing the use of machine learning as a supportive tool to recognize cardiac arrest in emergency calls. The AI system under assessment is currently in use in the city of Copenhagen in Denmark. The assessment is accomplished by an independent team composed of philosophers, policy makers, social scientists, technical, legal, and medical experts. By leveraging an interdisciplinary team, we aim to expose the complex trade-offs and the necessity for such thorough human review when tackling socio-technical applications of AI in healthcare. For the assessment, we use a process to assess trustworthy AI, called 1Z-Inspection® to identify specific challenges and potential ethical trade-offs when we consider AI in practice.

Prognostic association of frailty with post-arrest outcomes following cardiac arrest: A systematic review and meta-analysis

OBJECTIVE

To synthesize the current evidence examining the association between frailty and a series of post-arrest outcomes following the provision of cardiopulmonary resuscitation (CPR).

DATA SOURCES

We searched MEDLINE, PubMed (exclusive of MEDLINE), EMBASE, CINAHL, and Web of Science from inception to August 2020 for observational studies that examined an association between frailty and post-arrest health outcomes, including in-hospital and post-discharge mortality. We conducted citation tracking for all eligible studies.

STUDY SELECTION

Our search yielded 20,480 citations after removing duplicate records. We screened titles, abstracts and full-texts independently and in duplicate.

DATA EXTRACTION

The prognosis research strategy group (PROGRESS) and the critical appraisal and data extraction for systematic review of prediction modelling studies (CHARMS) guidelines were followed. Study and outcome-specific risk of bias were assessed using the Quality in Prognosis Studies (QUIPS) instrument. We rated the certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) recommendations for prognostic factor research.

DATA SYNTHESIS

Four studies were included in this review and three were eligible for statistical pooling. Our sample comprised 1,134 persons who experienced in-hospital cardiac arrest (IHCA). The mean age of the sample was 71 years. The study results were pooled according to the specific frailty instrument. Three studies used the Clinical Frailty Scale (CFS) and adjusted age (our minimum confounder); the presence of frailty was associated with an approximate three-fold increase in the odds of dying in-hospital after IHCA (aOR = 2.93; 95% CI = 2.43-3.53, high certainty). Frailty was also associated with decreased incidence of ROSC (return of spontaneous circulation) and discharge home following IHCA. One study with high risk of bias used the Hospital Frailty Risk Score and reported a 43% decrease in the odds of discharge home for patients with frailty following IHCA.

CONCLUSION

High certainty evidence was found for an association between frailty and in-hospital mortality following IHCA. Frailty is a robust prognostic factor that contributes valuable information and can inform shared-decision making and policies surrounding advance care directives.

Depiction of Resuscitation on Medical Dramas: Proposed Effect on Patient Expectations

The public has unrealistic views regarding the success of cardiopulmonary resuscitation, and one potential source of misinformation is medical dramas. Prior research has shown that depictions of resuscitation on television are skewed towards younger patients with acute injuries, while most cardiac arrests occur in older patients as a result of medical comorbidities. Additionally, the success rate of televised resuscitations on older shows has vastly exceeded good outcomes in the real world. We sought to understand resuscitation outcomes on current medical dramas and to review the literature for evidence that media affects patient decision-making. We reviewed medical dramas to evaluate the demographics of cardiac arrest victims and the success rate of resuscitations and compared the results to outcomes for real-world patients. Medical dramas continue to focus on trauma as the main cause of cardiac arrest and portray favorable outcomes more frequently than should be expected. Patients who believe the overly optimistic prognoses portrayed on television may be more likely to desire aggressive medical care in the face of serious illness. Healthcare workers should anticipate the need to counter misinformation when discussing patient goals of care and end-of-life planning.

Moving from "Do Not Resuscitate" Orders to Standardized Resuscitation Plans and Shared-Decision Making in Hospital Inpatients

Not for Cardiopulmonary Resuscitation (No-CPR) orders, or the local equivalent, help prevent futile or unwanted cardiopulmonary resuscitation. The importance of unambiguous and readily available documentation at the time of arrest seems self-evident, as does the need to establish a patient’s treatment preferences prior to any clinical deterioration. Despite this, the frequency and quality of No-CPR orders remains highly variable, while discussions with the patient about their treatment preferences are undervalued, occur late in the disease process, or are overlooked entirely.

This review explores the evolution of hospital patient No-CPR/Do Not Resuscitate decisions over the past 60 years. A process based on standardized resuscitation plans has been shown to increase the frequency and clarity of documentation, reduce stigma attached to the documentation of a No-CPR order, and support the delivery of medically appropriate and desired care for the hospital patient.

The outcome of in- and out-hospital cardiopulmonary arrest in the older population: a scoping review

Aim

We aimed to collect the available evidence on outcome regarding survival and quality of life after CPR following both IHCA and OHCA in the older population.

Findings

Hospital survival rates following IHCA and OHCA in the older population improved in the recent decade, though do not exceed 28.5% and 11.1%, respectively. The effect of age on outcome remains controversial and age should not be used as the sole decision criterium whether to initiate CPR.

Message

Future research should study frailty and resilience as an independent predictor regardless of age, and add broader, extensive QoL measures as outcome variables.

Supplementary Information

The online version contains supplementary material available at 10.1007/s41999-021-00454-y.

Purpose

We aimed to collect the available evidence on outcome regarding survival and quality of life after cardiopulmonary resuscitation (CPR) following both in-hospital cardiac arrest (IHCA) and out-of-hospital cardiac arrest (OHCA) in the older population.

Methods

A scoping review was performed studying published reviews after 2008, focusing on outcome of CPR in patients aged ≥ 70 years following IHCA and OHCA. In addition, 11 (IHCA) and 19 (OHCA) eligible studies published after the 2 included reviews were analyzed regarding: return of spontaneous circulation, survival until hospital discharge, long-term survival, neurological outcome, discharge location or other measurements for quality of life (QoL).

Results

The survival until hospital discharge ranged between 11.6 and 28.5% for IHCA and 0–11.1% for OHCA, and declined with increasing age. The same trend was seen regarding 1-year survival rates with 5.7–25.0% and 0–10% following IHCA and OHCA, respectively. A good neurological outcome defined as a Cerebral Performance Category (CPC) 1–2 was found in 11.5–23.6% (IHCA) and up to 10.5% (OHCA) of all patients. However, the proportion of CPC 1–2 among patients surviving until hospital discharge was 82–93% (IHCA) and 77–91.6% (OHCA). Few studies included other QoL measures as an outcome variable. Other risk factors aside from age were identified, including nursing home residency, comorbidity, non-shockable rhythm, non-witnessed arrest. The level of frailty was not studied as a predictor of arrest outcome in the included studies.

Conclusions

Hospital survival rates following IHCA and OHCA in the older population improved in the recent decade, though do not exceed 28.5% and 11.1%, respectively. The effect of age on outcome remains controversial and age should not be used as the sole decision criterium whether to initiate CPR. Future research should study frailty and resilience as an independent predictor regardless of age, and add broader, extensive QoL measures as outcome variables.

Association Between Patient Frailty and Postoperative Mortality Across Multiple Noncardiac Surgical Specialties

Importance

Frailty is an important risk factor for postoperative mortality. Whether the association between frailty and mortality is consistent across all surgical specialties, especially those predominantly performing lower stress procedures, remains unknown.

Objective

To examine the association between frailty and postoperative mortality across surgical specialties.

Design, Setting, and Participants

A cohort study was conducted across 9 noncardiac specialties in hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) and Veterans Affairs Surgical Quality Improvement Program (VASQIP) from January 1, 2010, through December 31, 2014, using multivariable logistic regression to evaluate the association between frailty and postoperative mortality. Data analysis was conducted from September 15, 2019, to April 30, 2020. Patients 18 years or older undergoing noncardiac procedures were included.

Exposures

Risk Analysis Index measuring preoperative frailty categorized patients as robust (Risk Analysis Index ≤20), normal (21-29), frail (30-39), or very frail (≥40). Operative Stress Score (OSS) categorized procedures as low (1-2), moderate (3), and high (4-5) stress. Specialties were categorized by case-mix as predominantly low intensity (>75% OSS 1-2), moderate intensity (50%-75%), or high intensity (<50%).

Main Outcomes and Measures

Thirty-day (both measures) and 180-day (VASQIP only) postoperative mortality.

Results

Of the patients evaluated in NSQIP (n = 2 339 031), 1 309 795 were women (56.0%) and mean (SD) age was 56.49 (16.4) years. Of the patients evaluated in VASQIP (n = 426 578), 395 761 (92.78%) were men and mean (SD) age was 61.1 (12.9) years. Overall, 30-day mortality was 1.2% in NSQIP and 1.0% in VASQIP, and 180-day mortality in VASQIP was 3.4%. Frailty and OSS distributions differed substantially across the 9 specialties. Patterns of 30-day mortality for frail and very frail patients were similar in NSQIP and VASQIP for low-, moderate-, and high-intensity specialties. Frailty was a consistent, independent risk factor for 30- and 180-day mortality across all specialties. For example, in NSQIP, for plastic surgery, a low-intensity specialty, the odds of 30-day mortality in very frail (adjusted odds ratio [aOR], 27.99; 95% CI, 14.67-53.39) and frail (aOR, 5.1; 95% CI, 3.03-8.58) patients were statistically significantly higher than for normal patients. This was also true in neurosurgery, a moderate-intensity specialty, for very frail (aOR, 9.8; 95% CI, 7.68-12.50) and frail (aOR, 4.18; 95% CI, 3.58-4.89) patients and in vascular surgery, a high-intensity specialty, for very frail (aOR, 10.85; 95% CI, 9.83-11.96) and frail (aOR, 3.42; 95% CI, 3.19-3.67) patients.

Conclusions and Relevance

In this study, frailty was associated with postoperative mortality across all noncardiac surgical specialties regardless of case-mix. Preoperative frailty assessment could be implemented across all specialties to facilitate risk stratification and shared decision-making.

Cardiopulmonary Resuscitation Preferences of People Receiving Dialysis

IMPORTANCE

Whether the cardiopulmonary resuscitation (CPR) preferences of patients receiving dialysis align with their values and other aspects of end-of-life care is not known.

OBJECTIVE

To describe the CPR preferences of patients receiving dialysis and how these preferences are associated with their responses to questions about other aspects of end-of-life care.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional survey study of a consecutive sample of patients receiving dialysis at 31 nonprofit dialysis facilities in 2 US metropolitan areas (Seattle, Washington, and Nashville, Tennessee) between April 22, 2015, and October 2, 2018. Analyses for this article were conducted between December 2018 and April 2020.

EXPOSURES

Participants were asked to respond to the question "If you had to decide right now, would you want CPR if your heart were to stop beating?" Those who indicated they would probably or definitely want CPR were categorized as preferring CPR.

MAIN OUTCOMES AND MEASURES

This study examined the association between preference for CPR and other treatment preferences, engagement in advance care planning, values, desired place of death, expectations about prognosis, symptoms, and palliative care needs.

RESULTS

Of the 1434 individuals invited to complete the survey, 1009 agreed to participate, and 876 were included in the analytic cohort (61.1%). The final cohort had a mean (SD) age of 62.6 (14.0) years; 492 (56.2%) were men, and 528 (60.3%) were White individuals. Among 738 of 876 participants (84.2%) who indicated that they would definitely or probably want CPR (CPR group), 555 (75.2%) wanted mechanical ventilation vs 13 of 138 (9.4%) of those who did not want CPR (do not resuscitate [DNR] group) (P < .001). A total of 249 of 738 participants (33.7%) in the CPR group vs 84 of 138 (60.9%) in the DNR group had documented treatment preferences (P < .001). In terms of values about future care, 171 participants (23.2%) in the CPR group vs 5 of 138 (3.6%) in the DNR group valued life prolongation (P < .001); 320 in the CPR group (43.4%) vs 109 of 138 in the DNR group (79.0%) valued comfort (P < .001); and 247 participants (33.5%) in the CPR group vs 24 of 138 (17.4%) in the DNR group were unsure about their wishes for future care (P < .001). In the CPR group, 207 (28.0%) had thought about stopping dialysis vs 62 of 138 (44.9%) in the DNR group (P < .001), and 181 (24.5%) vs 58 of 138 (42.0%) had discussed stopping dialysis (P = .001). No statistically significant associations were observed between CPR preference and documentation of a surrogate decision maker, thoughts or discussion of hospice, preferred place of death, expectations about prognosis, reported symptoms, or palliative care needs.

CONCLUSIONS AND RELEVANCE

The CPR preferences of patients receiving dialysis were associated with some, but not all, other aspects of end-of-life care. How participants responded to questions about these other aspects of end-of-life care were not always aligned with their CPR preference. More work is needed to integrate discussions about code status with bigger picture conversations about patients' values, goals, and preferences for end-of-life care.

Survival after in-hospital cardiopulmonary resuscitation from 2003 to 2013: An observational study before legislation on the life-sustaining treatment decision-making act of Korean patients

We analyzed cardiopulmonary resuscitation (CPR) rates, deaths preceded by CPR, and survival trends after in-hospital CPR, using a sample of nationwide Korean claims data for the period 2003 to 2013.The Korean National Health Insurance Service-National Sample Cohort is a stratified random sample of 1,025,340 subjects selected from among approximately 46 million Koreans. We evaluated the annual incidence of CPR per 1000 admissions in various age groups, hospital deaths preceded by CPR, and survival rate following in-hospital CPR. Analyses of the relationships between survival and patient and hospital characteristics were performed using logistic regression analysis.A total of 5918 in-hospital CPR cases from 2003 to 2013 were identified among eligible patients. The cumulative incidence of in-hospital CPR was 3.71 events per 1000 admissions (95% confidence interval 3.62-3.80). The CPR rate per 1000 admissions was highest among the oldest age group, and the rate decreased throughout the study period in all groups except the youngest age group. Hospital deaths were preceded by in-hospital CPR in 18.1% of cases, and the rate decreased in the oldest age group. The survival-to-discharge rate in all study subjects was 11.7% during study period, while the 6-month and 1-year survival rates were 8.0% and 7.2%, respectively. Survival tended to increase throughout the study period; however, this was not the case in the oldest age group. Age and malignancy were associated with lower survival rates, whereas myocardial infarction and diabetes mellitus were associated with higher survival rates.Our result shows that hospital deaths were preceded by in-hospital CPR in 18.1% of case, and the survival-to-discharge rate in all study subjects was 11.7% during the study period. Survival tended to increase throughout the study period except for the oldest age group. Our results provide reliable data that can be used to inform judicious decisions on the implementation of CPR, with the ultimate goal of optimizing survival rates and resource utilization.

Perspectives of emergency department attendees on outcomes of resuscitation efforts: origins and impact on cardiopulmonary resuscitation preference

Background

Previous studies have shown that individuals overestimate the success of cardiopulmonary resuscitation (CPR) while underestimating its morbidity. Although perceptions of CPR success affect medical care in the emergency department (ED), no ED-based studies have been done.

Objective

To survey ED patients and their companions to assess their expectations, hypothesising that variation in information sources, prior exposure to CPR, and healthcare experience would influence predicted CPR success rates.

Methods

A survey was carried out of adults (age >18 years) in the ED waiting area of a tertiary care hospital between June and September 2016. An optimism scale was created to reflect expected likelihood of survival after CPR, or CPR success, under several sets of circumstances. Potential predictors of optimism for CPR outcome were examined using linear regression. Associations between optimism and CPR preference were evaluated using a Wilcoxon rank-sum test.

Results

There were 500 respondents and 53% had performed or witnessed CPR, and/or participated in a CPR course (64%). Television was the main source of information about CPR for >95% of respondents. At least half (51–64%) of respondents estimated the success rate of CPR as over 75% in all situations. Estimated CPR success rates were unrelated to age, sex, race, spiritual beliefs or personal healthcare experience. More than 90% of respondents wanted to receive CPR. Less than one-third of respondents had discussed CPR with a medical provider, but most wished to do so.

Conclusion

Consistent with prior studies, individuals overestimate the success rate of CPR. Healthcare experience does not appear to mitigate optimism about CPR, and individuals overwhelmingly want CPR for themselves. Though few had talked about CPR with a medical provider, most wanted to have informed decision-making conversations. Such discussions could help patients obtain a more realistic view of CPR outcomes.

Prognostication in Serious Illness

Prognostication is a vital aspect of decision making because it provides patients and families with information to establish realistic and achievable goals of care, is used in determining eligibility for certain benefits, and helps in targeting interventions to those likely to benefit. Prognostication consists of 3 components: clinicians use their clinical judgment or other tools to estimate the probability of an individual developing a particular outcome over a specific period of time; this prognostic estimate is communicated in accordance with the patient's information preferences; the prognostic estimate is interpreted by the patient or surrogate and used in clinical decision making.

Validation of the Risk Analysis Index for Evaluating Frailty in Ambulatory Patients

BACKGROUND

Frailty is a marker of dependency, disability, hospitalization, and mortality in community-dwelling older adults. However, existing tools for measuring frailty are too cumbersome for rapid point-of-care assessment. The Risk Analysis Index (RAI) of frailty is validated in surgical populations, but its performance outside surgical populations is unknown.

OBJECTIVE

Validate the RAI in ambulatory patients.

DESIGN, SETTING, AND PARTICIPANTS

Observational cohort study of outpatient surgical clinics within the University of Pittsburgh Medical Center Healthcare System between July 1, 2016, and December 31, 2016. Frailty was assessed using the RAI. Current Procedural Terminology codes following RAI assessment identified patients with and without minor office-based procedures (eg, joint injection, laryngoscopy).

MAIN OUTCOMES AND MEASURES

All-cause 1-year mortality, assessed by stratified Cox proportional hazard models.

RESULTS

Of 28,059 patients, 13,861 were matched to a minor, office-based procedure and 14,198 did not undergo any procedure. The mean (SD) age was 56.7 (17.2) years; women constituted 15,797 (56.3%) of the cohort. Median time (interquartile range 25th-75th percentile) to measure RAI was 30 (22-47) seconds. Mortality among the frail was two to five times that of patients with normal RAI scores. For example, the hazard ratio for frail ambulatory patients without a minor procedure was 3.69 (95% confidence interval [CI] = 2.51-5.41), corresponding to 30-, 180-, and 365-day mortality rates of 2.9%, 11.2%, and 17.4%, respectively, compared to 0.3%, 2.3%, and 4.0% among patients with normal RAI scores. Discrimination of mortality (overall, and censored at 30, 180, and 365 days) was excellent, ranging from c = 0.838 (95% CI = 0.773-0.902) for 30-day mortality after minor procedures to c = 0.909 (95% CI = 0.855-0.964) without a procedure.

CONCLUSION

RAI is a valid, easily administered tool for point-of-care frailty assessment in ambulatory populations that may help clinicians and patients make better informed decisions about care choices-especially among patients considered high risk with a potentially limited life span.

Effect of Intensivist Communication in a Simulated Setting on Interpretation of Prognosis Among Family Members of Patients at High Risk of Intensive Care Unit Admission: A Randomized Trial

Importance

Discordance about prognosis between a patient's health care decision-making surrogate and the treating intensivist is common in the intensive care unit (ICU). Empowering families, friends, and caregivers of patients who are critically ill to make informed decisions about care is important, but it is unclear how best to communicate prognostic information to surrogates when a patient is expected to die.

Objective

To determine whether family members, who are often health care decision-making surrogates, interpret intensivists as being more optimistic when questions about prognosis in the ICU are answered indirectly.

Design, Setting, and Participants

This web-based randomized trial was conducted between September 27, 2019, and October 17, 2019, among a national sample of adult children, spouses, partners, or siblings of people with chronic obstructive pulmonary disease who were receiving long-term oxygen therapy. Participants were shown video vignettes depicting an intensivist answering a standardized question about the prognosis of a patient at high risk of death on day 3 of ICU admission. Participants were excluded if they had worked as a physician, nurse, or advanced health care practitioner. Data were analyzed from October 18, 2019, to November 12, 2019.

Interventions

Participants were randomized to view 1 of 4 intensivist communication styles in response to the question "What do you think is most likely to happen?": (1) a direct response (control), (2) an indirect response comparing the patient's condition with that of other patients, (3) an indirect response describing the patient's deteriorating physiological condition, or (4) redirection to a discussion of the patient's values and goals.

Main Outcomes and Measures

Participant responses to 2 questions: (1) "If you had to guess, what do you think the doctor thinks is the chance that your loved one will survive this hospitalization?" and (2) "What do you think are the chances that your loved one will survive this hospitalization?" answered using a 0% to 100% probability scale.

Results

Among 302 participants (median [interquartile range] age, 49 [38-59] years; 204 [68%] women) included in the trial, 165 (55%) were adult children of the individual with chronic obstructive pulmonary disease; 77 participants were randomized to view a direct response, 77 participants were randomized to view an indirect response referencing other patients, 68 participants were randomized to view an indirect response referencing physiological condition, and 80 participants were randomized to view a redirection response. Compared with participants who viewed a direct response, participants who viewed an indirect response referencing other patients (β = 10 [95% CI, 1-19]; P = .03), physiological condition (β = 10 [95% CI, 0-19]; P = .04), or redirection to a discussion of the patient's values and goals (β = 19 [95% CI, 10-28]; P < .001) perceived the intensivist to have a significantly more optimistic prognostic estimate.

Conclusions and Relevance

These findings suggest that family members interpret indirect or redirection responses to questions about prognosis in the ICU setting as more optimistic than direct responses.

Betting on CPR: a modern version of Pascal's Wager

Many patients believe that cardiopulmonary resuscitation (CPR) is more likely to be successful than it really is in clinical practice. Even when working with accurate information, some nevertheless remain resolute in demanding maximal treatment. They maintain that even if survival after cardiac arrest with CPR is extremely low, the fact remains that it is still greater than the probability of survival after cardiac arrest without CPR (ie, zero). Without realising it, this line of reasoning is strikingly similar to Pascal's Wager, a Renaissance-era argument for accepting the proposition for God's existence. But while the original argument is quite logical-if not universally compelling-the modern variant makes several erroneous assumptions. The authors here present a case of a patient who unwittingly appeals to Pascal's Wager to explain his request for maximal treatment, in order to highlight the crucial divergences from the original Wager. In understanding the faulty assumptions inherent in the application of Pascal's Wager to code status decisions-and identifying the underlying motivations which the Wager serves to confirm-providers can better ensure that the true values and preferences of patients are upheld.

Predicting the probability of survival with mild or moderate neurological dysfunction after in-hospital cardiopulmonary arrest: The GO-FAR 2 score

BACKGROUND

The Good Outcome Following Attempted Resuscitation (GO-FAR) Score uses pre-arrest factors to predict survival after In-Hospital Cardiac Arrest (IHCA) with minimal neurological dysfunction, (cerebral performance category (CPC) ≤1). Moderate neurological dysfunction (CPC ≤2) may be a more acceptable outcome.

OBJECTIVE

To predict survival after IHCA with mild or moderate neurological dysfunction based on pre-arrest factors.

METHODS

52,468 patients with IHCA from 2012-2017. Data was divided into training (44%), testing (22%), and validation (34%) sets. Univariate analysis was used to identify variables with >3% difference in survival with CPC ≤2. These variables carried forward to the multivariate logistic regression model. The most parsimonious model that best classified patients as having a very poor (≤5%), below average (≤10%), average (11%-30%), or above average (>30%) likelihood of survival with CPC ≤2 was chosen.

RESULTS

Age >85, admission CPC <2, and non-surgical admission were strongly association with poor survival (-12.1%, -14.4%, and -18%, respectively). Nine variables were included in the logistic regression analysis. The final updated model, GO FAR 2, categorized 6.2% of patients with a very poor predicted survival, 24.8% of patients with a below average predicted survival, and 11.3% with above average predicted survival. The observed survival among those with very poor predicted survival was 4.5%.

CONCLUSION

The GO FAR 2 score provides clinicians with a prognostic estimate of the likelihood of a good outcome after IHCA based on pre-arrest patient factors. Future research is required to validate the GO-FAR 2 score.

Pre-arrest and intra-arrest prognostic factors associated with survival after in-hospital cardiac arrest: systematic review and meta-analysis

OBJECTIVE

To determine associations between important pre-arrest and intra-arrest prognostic factors and survival after in-hospital cardiac arrest.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Medline, PubMed, Embase, Scopus, Web of Science, and the Cochrane Database of Systematic Reviews from inception to 4 February 2019. Primary, unpublished data from the United Kingdom National Cardiac Arrest Audit database.

STUDY SELECTION CRITERIA

English language studies that investigated pre-arrest and intra-arrest prognostic factors and survival after in-hospital cardiac arrest.

DATA EXTRACTION

PROGRESS (prognosis research strategy group) recommendations and the CHARMS (critical appraisal and data extraction for systematic reviews of prediction modelling studies) checklist were followed. Risk of bias was assessed by using the QUIPS tool (quality in prognosis studies). The primary analysis pooled associations only if they were adjusted for relevant confounders. The GRADE approach (grading of recommendations assessment, development, and evaluation) was used to rate certainty in the evidence.

RESULTS

The primary analysis included 23 cohort studies. Of the pre-arrest factors, male sex (odds ratio 0.84, 95% confidence interval 0.73 to 0.95, moderate certainty), age 60 or older (0.50, 0.40 to 0.62, low certainty), active malignancy (0.57, 0.45 to 0.71, high certainty), and history of chronic kidney disease (0.56, 0.40 to 0.78, high certainty) were associated with reduced odds of survival after in-hospital cardiac arrest. Of the intra-arrest factors, witnessed arrest (2.71, 2.17 to 3.38, high certainty), monitored arrest (2.23, 1.41 to 3.52, high certainty), arrest during daytime hours (1.41, 1.20 to 1.66, high certainty), and initial shockable rhythm (5.28, 3.78 to 7.39, high certainty) were associated with increased odds of survival. Intubation during arrest (0.54, 0.42 to 0.70, moderate certainty) and duration of resuscitation of at least 15 minutes (0.12, 0.07 to 0.19, high certainty) were associated with reduced odds of survival.

CONCLUSION

Moderate to high certainty evidence was found for associations of pre-arrest and intra-arrest prognostic factors with survival after in-hospital cardiac arrest.

Frailty and associated outcomes and resource utilization following in-hospital cardiac arrest

BACKGROUND

In-hospital cardiac arrest (IHCA) is common and associated with high mortality. Frailty is increasingly recognized as a predictor of worse prognosis among critically ill patients, but its association with outcomes and resource utilization following IHCA is unknown.

METHODS

We performed a retrospective analysis (2013-2016) of a prospectively collected registry from two hospitals of consecutive hospitalized adult patients with IHCA occurring on the hospital wards. We defined frailty using the Clinical Frailty Scale (CFS) score ≥5. CFS scores were based on validated medical review criteria. The primary outcome is hospital mortality. Secondary outcomes include return of spontaneous circulation (ROSC), discharge to long-term care, and hospital costs. We used multivariable logistic regression to adjust for known confounders.

RESULTS

We included 477 patients, and 124 (26.0%) had frailty. Frailty was associated with increased odds of hospital death (adjusted odds ratio [aOR]: 2.91 [95% confidence interval [CI]: 2.37-3.48) and discharge to long-term care (aOR 1.94 [95% CI: 1.57-2.32]). Compared with patients without frailty, patients with frailty had decreased odds of ROSC following IHCA (aOR 0.63 [95% CI: 0.41-0.93]). No difference in mean total costs was demonstrated between patients with and without frailty ($50,799 vs. $45,849). Frail patients did have higher cost-per-survivor ($947,546 vs. $161,550).

CONCLUSIONS

Frail individuals who experience an IHCA are more likely to die in hospital or be discharged to long-term care, and less likely to achieve ROSC in comparison with individuals who are not frail. The hospital costs per-survivor of IHCA are increased when frailty is present.

Development and Validation of the Nursing Home Minimum Data Set 3.0 Mortality Risk Score (MRS3)

Background

To develop a score to predict mortality using the Minimum Data Set 3.0 (MDS 3.0) that can be readily calculated from items collected during nursing home (NH) residents' admission assessments.

Participants

We developed a training cohort of Medicare beneficiaries newly admitted to United States NHs during 2012 (N = 1,426,815) and a testing cohort from 2013 (N = 1,160,964).

Methods

Data came from the MDS 3.0 assessments linked to the Medicare Beneficiary Summary File. Using the training dataset, we developed a composite MDS 3.0 Mortality Risk Score (MRS3) consisting of 17 clinical items and patients' age groups based on their relation to 30-day mortality. We assessed the calibration and discrimination of the MRS3 in predicting 30- and 60-day mortality and compared its performance to the Charlson Comorbidity Index and the clinician's assessment of 6-month prognosis measured at admission.

Results

The 30- and 60-day mortality rates for the testing population were 2.8% and 5.6%, respectively. Results from logistic regression models suggest that the MRS3 performed well in predicting death within 30 and 60 days (C-Statistics of 0.744 [95% confidence limit (CL) = 0.741, 0.747] and 0.709 [95% CL = 0.706, 0.711], respectively). The MRS3 was a superior predictor of mortality compared to the Charlson Comorbidity Index (C-statistics of 0.611 [95% CL = 0.607, 0.615] and 0.608 [95% CL = 0.605, 0.610]) and the clinicians' assessments of patients' 6-month prognoses (C-statistics of 0.543 [95% CL = 0.542, 0.545] and 0.528 [95% CL = 0.527, 0.529]).

Conclusions

The MRS3 is a good predictor of mortality and can be useful in guiding decision-making, informing plans of care, and adjusting for patients' risk of mortality.

The cause of anorexia and proportion of its recovery in older adults without underlying disease: Results of a retrospective study

Aim

It is difficult to determine whether or not end-of-life care is necessary for frail older adults complaining of anorexia without underlying disease, such as cancer or organ failure. The main reason for this is the lack of the specification of the anorexia cause and no understanding of the cause-providing factor and the prognostic factor. This study aimed to clarify the cause of anorexia, and the determinant of the cause and recovery from anorexia.

Methods

Retrospective chart reviews were conducted on patients with anorexia without an underlying disease who were aged ≥65 years and visited the emergency department of a single tertiary care center between 2016 and 2017. Patient characteristics at hospital visit, the cause of anorexia, and diagnostic modalities were summarized. The diagnosis-providing rate, recovery rate, and the association between them were analyzed.

Results

Eighty-three patients (mean age 82.3 years; 50.6% male) were investigated. In 67 patients (81%), the causes of anorexia were identified, including 18 patients (22%) with infection, 13 (16%) with benign gastrointestinal diseases, and 7 (8%) with cardiovascular diseases. In 16 patients (19%), the causes of anorexia were not identified despite examinations. The modality that most contributed to diagnosis was plain computed tomography followed by blood tests. The value regarding information in history-taking and physical examinations was limited. Sixty-five patients (78%) recovered. Only 73% of patients with a definite cause recovered; all patients with an unknown cause recovered.

Conclusions

Older adults with anorexia are not always at the end of life, and efforts to identify the cause are crucial. Moreover, it is vital to realize the limitations associated with the treatment of infections and cardiovascular diseases.

How to discuss about do-not-resuscitate in the intensive care unit?

The improvement in cardiopulmonary resuscitation quality has reduced the mortality of individuals treated for cardiac arrest. However, survivors have a high risk of severe brain damage in cases of return of spontaneous circulation. Data suggest that cases of cardiac arrest in critically ill patients with non-shockable rhythms have only a 6% chance of returning of spontaneous circulation, and of these, only one-third recover their autonomy. Should we, therefore, opt for a procedure in which the chance of survival is minimal and the risk of hospital death or severe and definitive brain damage is approximately 70%? Is it worth discussing patient resuscitation in cases of cardiac arrest? Would this discussion bring any benefit to the patients and their family members? Advanced discussions on do-not-resuscitate are based on the ethical principle of respect for patient autonomy, as the wishes of family members and physicians often do not match those of patients. In addition to the issue of autonomy, advanced discussions can help the medical and care team anticipate future problems and, thus, better plan patient care. Our opinion is that discussions regarding the resuscitation of critically ill patients should be performed for all patients within the first 24 to 48 hours after admission to the intensive care unit.

Toward Understanding the Relationship Between Prioritized Values and Preferences for Cardiopulmonary Resuscitation Among Seriously Ill Adults

CONTEXT

Prioritizing among potentially conflicting end-of-life values may help patients discriminate among treatments and allow clinicians to align treatments with values.

OBJECTIVES

To investigate end-of-life values that patients prioritize when facing explicit trade-offs and identify predictors of patients whose values and treatment preferences seem inconsistent.

METHODS

Analysis of surveys from a multi-center cluster-randomized trial of patients with serious illness. Respondents prioritized end-of-life values and identified cardiopulmonary resuscitation (CPR) preferences in two health states.

RESULTS

Of 535 patients, 60% prioritized relief of discomfort over extending life, 17% prioritized extending life over relief of discomfort, and 23% were unsure. Patients prioritizing extending life were most likely to prefer CPR, with 93% preferring CPR in current health and 67% preferring CPR if dependent on others, compared with 69% and 21%, respectively, for patients prioritizing relief of discomfort, and 78% and 33%, respectively, for patients unsure of their prioritized value (P < 0.001 for all comparisons). Among patients prioritizing relief of discomfort, preference for CPR in current health was less likely among older patients (odds ratio 0.958 per year; 95% CI 0.935, 0.981) and more likely with better self-perceived health (odds ratio 1.402 per level of health; 95% CI 1.090, 1.804).

CONCLUSION

Clinicians face challenges as they clarify patient values and align treatments with values. Patients' values predicted CPR preferences, but a substantial proportion of patients expressed CPR preferences that appeared potentially inconsistent with their primary value. Clinicians should question assumptions about relationships between values and CPR preferences. Further research is needed to identify ways to use values to guide treatment decisions.

Quality of life after in-hospital cardiopulmonary resuscitation for patients over the age of 80 years

Objectives

Success of in-hospital resuscitation decreases with age; however, national data show that 11.3% of patients over 80 years survive to discharge. There are few published qualitative data about the quality of life for these patients postsuccessful resuscitation. We aimed to investigate postresuscitation quality of life in patients over the age of 80 through a series of case studies.

Methods

All patients over the age of 80 years, who received cardiopulmonary resuscitation (CPR) at our district general hospital in 2015–2016, were included. Success of resuscitation, survival at day 1 and to discharge were recorded. For patients who survived to 1 day and beyond, case reports were written to create individual patient stories.

Results

47 patients over the age of 80 years received CPR at Musgrove Park Hospital over a 2-year period. Five (10.6%) survived to discharge. Of those surviving to discharge, two had substantial functional decline, requiring discharge to nursing homes having previously been independent. Of the five families/patients who commented on their experience, only one expressed a positive view. When discussed, the majority of patients/families opted for a Do Not Attempt CPR.

Conclusion

Our results have shown that there is a risk of substantial functional decline associated with successful CPR in those patients over the age of 80 years. The majority of patients and relatives contacted after successful resuscitation expressed a negative view of the experience. Our study highlights the importance of having early informed discussions with patients and families about CPR in order to avoid detrimental outcomes and ensure patient wishes are correctly represented.

A critical review of the factors leading to cardiopulmonary resuscitation as the default position of hospitalized patients in the USA regardless of severity of illness

BACKGROUND

Physicians are occasionally faced with patients requesting full resuscitation against medical advice. More commonly, neither patients nor their family members make such a request, but physicians simply presume that providing cardiopulmonary resuscitation comports with the patient's wishes. In the USA, in contrast to other countries, a unilateral Do-Not-Resuscitate order by the physician is either forbidden by State Statute or not enforced by hospital policy. Unless otherwise specified, performing cardiopulmonary resuscitation on all hospitalized patients, regardless of the severity of the underlying illness, is the default position. Unlike other medical interventions, no deference is given to the medical judgment of the physician even when a patient is in the last days of a terminal illness. We examine the factors that have led to cardiopulmonary resuscitation having this unique status.

MAIN BODY

A review of the historical factors leading to cardiopulmonary resuscitation as the default position was undertaken. Articles published in the medical literature, lay-press articles, legislative enactments of law, and judicial opinions involving the issue of Do-Not-Resuscitate and cardiopulmonary resuscitation were reviewed regarding their impact on physician and hospital practice in the USA.

CONCLUSION

A critical review of the historical factors reveals that the rapid dissemination of cardiopulmonary training for the public, inaccuracies in the media regarding successful cardiopulmonary resuscitation, well-meaning legislative efforts with inadvertent consequences, and judicial interpretation outside the generally accepted concept of malpractice law have contributed to the situation faced by today's physicians and hospitals in the USA.

Predictors Associated with Survival Among Elderly In-Patients Who Receive Cardiopulmonary Resuscitation in Japan: An Observational Cohort Study

BACKGROUND

Little is known about the outcomes of in-hospital cardiopulmonary resuscitation (CPR) in Asian populations including elderly patients in Japan.

OBJECTIVE

To determine the survival outcome of in-hospital CPR among elderly patients in Japan, and to identify predictors associated with survival.

DESIGN

Retrospective cohort study in 81 Japanese hospitals from April 1, 2010 to March 31, 2016.

PATIENTS

We included elderly patients (age ≥ 65 years) who received CPR after 2 days of hospitalization.

MAIN MEASURES

The primary outcome was survival at hospital discharge and the secondary outcomes were the discharge disposition and consciousness level of patients who survived to hospital discharge. To determine predictors associated with survival after in-hospital CPR, we fit multivariable models for patient-level and institutional-level factors.

KEY RESULTS

Among the 5365 patients who received CPR, 595 (11%) survived to discharge. Of those who survived to discharge, 46% of patients were discharged home, and 10% of patients were comatose at discharge. Older age and higher burden of comorbidities were associated with reduced survival. The adjusted OR was 0.35 (95% CI, 0.22-0.55) for age ≥ 90 years compared to age 65-69 years, and 0.68 (95% CI, 0.48-0.97) for Charlson Comorbidity Index score of ≥ 4 compared with score of 0. Other predictors of reduced survival included receiving CPR on weekends compared to weekdays (AOR, 0.63; 95% CI, 0.51-0.77) and in small hospitals compared to large hospitals (AOR, 0.58; 95% CI, 0.40-0.83).

CONCLUSIONS

Among elderly patients in Japan, the survival rate of in-hospital CPR was approximately one in ten, and less than half of these patients were discharged home. In addition to older age and higher illness burden, receiving CPR on weekends and/or in small hospitals were significant predictors of reduced survival. These findings should be considered in advanced care planning discussions with elderly patients to avoid subjecting patients to CPR that are likely futile.

Low Rates of Survival Seen in Orthopedic Patients Receiving In-Hospital Cardiopulmonary Resuscitation

INTRODUCTION

Despite awareness of overall poor survival rates following cardiopulmonary resuscitation (CPR), some orthopedic patients with significant comorbidities continue to have inappropriate resuscitation plans. Furthermore, in certain injury groups such as patients with hip fractures, survival outcome data are very limited; current discussions regarding resuscitation plans may be inaccurate. This study assesses survival in orthopedic patients following CPR, to inform decision-making between physicians, surgeons, and patients.

METHODS

A dual center, retrospective cohort study was performed analyzing all orthopedic admissions that received CPR over a 25-month period, with a minimum of 1 year follow-up. National Cardiac Arrest Audit data, "mortality and morbidity" meeting records, National Hip Fracture Databases, and electronic notes were analyzed. Survival duration was measured, alongside reason for admission, location CPR occurred, and initial rhythm encountered.

RESULTS

Thirty-two patients received CPR over the 25-month period (median age: 83; range: 30-96). Three (9%) of 32 patients survived to discharge. Only 1 of the 26 patients older than 65 years survived to discharge. Fifteen (47%) of 32 had hip fractures, where 4 (27%) of 15 of this group survived 24 hours; none survived to discharge. When recorded, 22 (92%) of 24 initially had a nonshockable rhythm.

DISCUSSION

Cardiopulmonary resuscitation was conceptualized as a treatment for reversible cardiopulmonary causes. When used in trauma and orthopedic patients, especially older and/or hip fracture patients, it seldom led to hospital discharge. Different admission practices such as "front door" orthogeriatric reviews may explain the contrast in usage of CPR between the hospitals.

CONCLUSION

Survival rates following CPR were very low, with it proving specifically ineffective in hip fracture patients. Although every decision about resuscitation should be patient centered and individualized, this study will allow clinicians to be more realistic about outcomes from CPR, particularly in the hip fracture group.
