A two-point strategy to clarify prognosis in >80 year olds experiencing out of hospital cardiac arrest. Resuscitation 2023; 191:109962. [PMID: 37683995 DOI: 10.1016/j.resuscitation.2023.109962] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 08/29/2023] [Accepted: 08/31/2023] [Indexed: 09/10/2023]
Abstract
BACKGROUND The global population is aging, with the number of ≥80-year-olds projected to triple over the next 30 years. Rates of out-of-hospital cardiac arrest (OHCA) are also increasing within this age group. METHODS The Victorian Ambulance Cardiac Arrest Registry was utilised to identify OHCAs in patients aged ≥80 years between 2002-2021. Predictors of survival to discharge were defined and a prognostic score derived from this cohort. RESULTS 77,628 patients experienced OHCA of whom 25,269 (32.6%) were ≥80 years (80-90 years = 18,956; 90-100 years = 6,148; >100 years = 209). The number of patients ≥80 years increased over time both absolutely (p = 0.002) and proportionally (p = 0.028). 619 (2.4%) patients survived to discharge without change over time. Older ages had no difference in witnessed OHCA status but were less likely to have shockable rhythm (OR 0.50 (95% CI 0.44-0.57) for 90-100-year-olds, OR 0.28 (95% CI 0.12-0.63) for 90-100-year-olds). If OHCA was witnessed and there was a shockable rhythm then survival was 14%; if one factor was present survival was 5-6% and if neither factor was present, survival was 0.09%. These survival rates enabled derivation of a simplified prognostic assessment score - the '15/5/0' score - highly comparable to a previously-published American cohort. CONCLUSIONS Elderly OHCA rates have increased to one-third of caseload. The most important factors predicting survival were whether the OHCA was witnessed and there was a shockable rhythm. We present a simple two-point '15/5/0' prognostic score defining which patients will gain most from advanced resuscitative measures.

[PMID: 34971720 DOI: 10.1016/j.resuscitation.2021.12.026] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 12/21/2021] [Accepted: 12/21/2021] [Indexed: 12/21/2022]
Abstract
AIMS Long term outcomes after out-of-hospital cardiac arrest (OHCA) are not well understood. This study aimed to evaluate the long-term (1-year and beyond) survival outcomes, including overall survival and survival with favorable neurological status and the quality-of-life (QOL) outcomes, among patients who survived the initial OHCA event (30 days or till hospital discharge). METHODS Embase, Medline and PubMed were searched for primary studies (randomized controlled trials, cohort and cross-sectional studies) which reported the long-term survival outcomes of OHCA patients. Data abstraction and quality assessment was conducted, and survival at predetermined timepoints were assessed via single-arm meta-analyses of proportions, using generalized linear mixed models. Comparative meta-analyses were conducted using the Mantel-Haenszel Risk Ratio (RR) estimates, using the DerSimonian and Laird model. RESULTS 67 studies were included, and among patients that survived to hospital discharge or 30-days, 77.3% (CI=71.2-82.4), 69.6% (CI=54.5-70.3), 62.7% (CI=54.5-70.3), 46.5% (CI=32.0-61.6), and 20.8% (CI=7.8-44.9) survived to 1-, 3-, 5-, 10- and 15-years respectively. Compared to Asia, the probability of 1-year survival was greater in Europe (RR=2.1, CI=1.8-2.3), North America (RR=2.0, CI=1.7-2.2) and Oceania (RR=1.9,CI=1.6-2.1). Males had a higher 1-year survival (RR:1.41, CI=1.25-1.59), and patients with initial shockable rhythm had improved 1-year (RR=3.07, CI=1.78-5.30) and 3-year survival (RR=1.45, CI=1.19-1.77). OHCA occurring in residential locations had worse 1-year survival (RR=0.42, CI=0.25-0.73). CONCLUSION Our study found that up to 20.8% of OHCA patients survived to 15-years, and survival was lower in Asia compared to the other regions. Further analysis on the differences in survival between the regions are needed to direct future long-term treatment of OHCA patients.

Abstract
Introduction : L’objectif de notre étude est de déterminer si l’âge des patients en arrêt cardiaque (AC) a une influence sur les durées de réanimation cardiopulmonaire (RCP) par les équipes préhospitalières.
Patients et méthodes : Nous avons réalisé une étude monocentrique, prospective, à partir des données de notre centre hospitalier universitaire, issues du Registre électronique des arrêts cardiaques. Ont été inclus tous les patients ayant présenté un AC, hormis ceux retrouvés en état de rigidité cadavérique ou qui avaient préalablement exprimé des directives anticipées sur leur fin de vie. Les patients ont été séparés en deux groupes selon leur âge : les moins de 75 ans et ceux de 75 ans et plus. Le critère de jugement principal était la durée de RCP spécialisée décidée par le médecin de l’équipe préhospitalière.
Résultats : Du 1er janvier au 31 décembre 2015, sur 253 patients victimes d’AC, 188 (74 % d’hommes, 78 % d’asystolie) ont bénéficié d’une RCP par une équipe du Service mobile d’urgence et de réanimation. Il y a eu 39 % de récupération d’une activité cardiaque spontanée (RACS). Seuls 31 % des patients étaient admis vivants à l’hôpital, ils étaient 6 % à j30. La durée de RCP était plus importante pour les patients de moins de 75 ans (29 ± 15 vs 23 ± 19 minutes ; p < 0,01). Mais pour les patients ayant une RACS, la durée de RCP était identique entre les deux groupes (16 ± 10 vs 14 ± 9 minutes ; p = 0,34). La survie des patients de 75 ans et plus était de 10 vs 22 % pour les moins de 75 ans (p = 0,35).
Conclusion : Notre étude suggère que l’âge des patients influence négativement les durées de réanimation des équipes préhospitalières.

Abstract
Objective Out-of-hospital cardiac arrest (OHCA) patients unresponsive to basic life support are frequently transferred to emergency departments (EDs) for further resuscitation. Although some survive with good neurologic outcomes, additional resuscitation in EDs is often futile. Without a dedicated termination of resuscitation (TOR) rule for ED resuscitation, the decision when to stop the resuscitation is up to emergency physicians. In this study, we assessed the association between patient characteristics and duration of resuscitation in EDs to understand how emergency physicians decide when to terminate cardiopulmonary resuscitation. Methods A retrospective analysis of the OHCA registry of a single ED was conducted. Adult (18 years or older) patients without any return of spontaneous circulation (ROSC) after unsuccessful ED advanced cardiac life support were included. The primary endpoint was duration of resuscitation attempts. Prehospital and demographic factors were assessed as independent variables. The relationship between these factors and duration of resuscitative attempts was analyzed with multivariable quantile regression. Results From January 2008 to August 2012, ED resuscitation was terminated without ROSC in 266 patients (53.5%). The duration of resuscitative attempts was significantly shorter if any of the currently recognized poor prognostic factors was present. Interestingly, controversial factors such as female sex and older age were significantly associated with shorter resuscitation duration, while factors definitively indicating poor prognosis, such as severe trauma and poor baseline neurological status, showed no significant association. Conclusion The results of this study suggest that physicians adjust the resuscitation duration according to their subjective prediction of futility despite the absence of evidence-based TOR guidelines.

Abstract
UNLABELLED BACKGROUND A growing elderly population along with advances in equipment and approaches for pre-hospital resuscitation necessitates up-to-date information when developing policies to improve elderly out-of-hospital cardiac arrest (OHCA) outcomes. We examined the effects of bystander type (family or non-family) intervention on 1-month outcomes of witnessed elderly OHCA patients. METHODS Data from a total of 85,588 witnessed OHCA events in patients aged ≥65 years, which occurred from 2005 to 2008, were obtained from a nationwide population-based database. Patients were stratified into three age categories (65-74, 75-84, ≥85 years), and the effects of bystander type (family or non-family) on initial cardiac rhythm, rate of bystander cardiopulmonary resuscitation (CPR), and 1-month outcomes were assessed. RESULTS The overall survival rate was 6.9% (65-74 years: 9.8%, 75-84 years: 6.9%, ≥85 years: 4.6%). Initial VF/VT was recorded in 11.1% of cases with a family bystander and 12.9% of cases with a non-family bystander. The rate of bystander CPR was constant across the age categories in patients with a family bystander and increased with advancing age categories in patients with a non-family bystander. Patients having a non-family bystander were associated with significantly higher 1-month rates of survival (OR: 1.26; 95% CI: 1.19-1.33) and favorable neurological status (OR: 1.47; 95% CI: 1.34-1.60). CONCLUSIONS Elderly patient OHCA events witnessed by a family bystander were associated with worse 1-month outcomes than those witnessed by a non-family bystander. Healthcare providers should consider targeting potential family bystanders for CPR education to increase the rate and quality of bystander CPR.

Abstract
OBJECTIVE The impact of prehospital care after the return of spontaneous circulation in out-of-hospital cardiac arrest patients is not known. This study describes adherence to the resuscitation guidelines, factors associated with poor adherence and possible impact of prehospital postresuscitation care on the outcome of out-of-hospital cardiac arrest. METHODS One hundred and fifty-seven Finnish out-of-hospital cardiac arrest patients hospitalized during 1 year, were analyzed retrospectively. Patient and arrest characteristics, prehospital postresuscitation care and survival to hospital discharge were analyzed using multivariate logistic regression. RESULTS Forty percent of the patients received care accordant with the guidelines. Male sex (P=0.045), witnessed arrest (P=0.031), initial ventricular fibrillation/ventricular tachycardia rhythm (P=0.007) and the presence of an emergency physician (P=0.017) were associated with care in line with the current guidelines. In multivariate logistic regression analysis, age over median (odds ratio=3.6, 95% confidence interval 1.5-8.6), nonventricular fibrillation/ventricular tachycardia initial rhythm (odds ratio=4.0, 95% confidence interval 1.6-9.8), administration of adrenaline (odds ratio=7.0, 95% confidence interval 2.3-21.4) and unsatisfactory prehospital postresuscitation care (odds ratio=2.5, 95% confidence interval 1.1-6.3) were associated with a failure to survive up to hospital discharge. CONCLUSIONS Less than 50% of out-of-hospital cardiac arrest patients received prehospital postresuscitation care compatible with the current guidelines. Markers of poor prognosis were associated with unsatisfactory care, which in turn was more frequent among the patients who did not survive to hospital discharge. The importance of the guidelines should be highlighted in the future.

Abstract
OBJECTIVE Early defibrillation programs have improved long-term outcomes following out-of-hospital cardiac arrest from ventricular fibrillation. Although long-term collective quality of life and survival are favorable, there are subsets of these patients who may be predisposed to worse outcomes. In particular, elderly patients may present with more comorbid medical conditions affecting their outcome. However, the impact of age on mortality rate and quality of life after rapid defibrillation is unknown. DESIGN Observational study. SETTING Hospital. SUBJECTS All patients with an out-of-hospital cardiac arrest between November 1990 and January 2001 who received rapid defibrillation for ventricular fibrillation in Olmsted County, Minnesota. All patients received treatment at one hospital. INTERVENTIONS Long-term outcome and quality of life were followed. Survival was estimated using the Kaplan-Meier method. The quality of life was established by an SF-36 survey. MEASUREMENTS AND MAIN RESULTS Two hundred patients presented in ventricular fibrillation out-of-hospital cardiac arrest; of these, 138 (69%) survived to hospital admission, seven (4%) died in the emergency department, and 79 (39%) were discharged neurologically intact. The average age was 62+/-16 yrs, with 51% (n = 40) of the population > or =65. The average length of follow-up was 4.8+/-3.0 yrs. The 5-yr survival in patients <65 was 94% (confidence interval, 86-100%) and 66% (confidence interval, 52-84%) in patients > or =65 (p <.001). The observed survival in the younger group was not different from that expected in a U.S. age- and gender-matched population. However, in the older group, the expected survival was significantly lower compared with an age- and gender-matched U.S. population (p =.01) but similar to an age-, gender-, and disease-matched cohort of patients from Olmsted County not experiencing an arrest. In both age-dependent cohort populations, the quality of life scores crossed the norm in all categories with exception of vitality in patients >65 yrs old (42.6+/-7.2). In direct comparison between the two patient groups, the older cohort reported lower levels of physical functioning (p =.002), role-emotional score (p =.03), and role-physical score (p =.007). Other SF-36 scores were not different between the groups. Sixty-five percent of patients <65 yrs returned to work compared with 56% of older patients. CONCLUSIONS The survival rate for ventricular fibrillation out-of-hospital cardiac arrest is significantly improved by the presence of a rapid defibrillation program. In patients <65 yrs old, long-term survival is equal to that of normal individuals and quality of life is similar to the general population. The survival, although high, in older patients is less than that in age-matched healthy controls, and physical and emotional quality of life scores are decreased.

Abstract
INTRODUCTION The impact of the immediate in-hospital post-resuscitation care after out-hospital cardiac arrest is not well known. Based on treatment variables and laboratory findings a multiple logistic regression model was created for the prediction of survival at 6 months from the event. MATERIALS AND METHODS A retrospective study of the hospital charts of patients successfully resuscitated and treated in one of three community hospitals from 1998 to 2000. In addition to several pre-hospital variables, the mean 72 h values of clinical features such as blood pressure, blood glucose concentration and initiated treatment used, were included in a forward multiple logistic regression model predicting survival at 6 months from the event. RESULTS The charts of 98 out of a total of 102 patients were sufficiently complete and included in the analysis. Variables independently associated with survival were age, delay before a return of spontaneous circulation, mean blood glucose and serum potassium, and the use of beta-blocking agents during post-resuscitation care. When those patients who were assigned a 'do not attempt to resuscitate' (DNAR) order during the first 72 h of treatment were excluded from the analysis blood glucose, blood potassium and the use beta-blocking agents remained independently associated with survival. CONCLUSION This study suggests that in-hospital factors are associated with survival from out-of-hospital cardiac arrest. The mean blood glucose and serum potassium during the first 72 h of treatment and the use of beta-blocking agents were significantly and independently associated with survival.

Abstract
Despite all of the progress in reanimating patients in cardiac arrest over the last half century, resuscitation attempts usually fail to restore spontaneous circulation. Thus, the most common of all resuscitation decisions after initiation remains the decision to stop. An entire library of research and guidelines for terminating resuscitative efforts has been developed in the past decade. However, this most central decision is often left open to chance, provider preference, family wishes, futility judgments, and resource concerns-a host of subjective considerations at the bedside and beyond. This article sheds light on these considerations, acknowledging the pivotal role that resuscitation science and guidelines can play in the multifactorial decision to discontinue resuscitative efforts.

Abstract
OBJECTIVE To examine whether previously observed sex-related differences in coronary artery disease syndromes also apply to patients with out-of-hospital sudden cardiac arrest, a probable subset of patients with coronary artery disease who are easy to recognize and are treated in a standardized fashion. DESIGN Prospective, population-based study conducted over a 6-yr period. SETTING A large urban municipality (population, 1.1 million) served by a single emergency medical services system with centralized medical direction and standardized protocols. PATIENTS All patients with out-of-hospital, nontraumatic, primary cardiac arrest. INTERVENTIONS Standardized advanced cardiac life support protocols. MEASUREMENTS AND MAIN RESULTS During the 6 yrs of the study, 4147 consecutive patients were studied, 42% of whom were women (p <.001). Although women were significantly older than men (mean age, 68.7 +/- 18 vs. 61.7 +/- 17 yrs; p =.001), there were no significant differences for the percentages of witnessed and unwitnessed arrests, response intervals, and the length and type of treatment provided. Although men were more likely to have ventricular fibrillation/ventricular tachycardia on presentation (41% vs. 30%), women had more asystole (8.8% vs. 7%) and (organized) pulseless electrical activity than men (24% vs. 18%; p <.001). Nevertheless, more women were resuscitated (13.5% vs. 10.7%; p =.005), particularly women with non-ventricular fibrillation/ventricular tachycardia presentation (12.6% vs. 9.6%; p <.02). These differences were more pronounced when controlling for age (95% confidence interval, 1.44 [1.25-1.74]). CONCLUSIONS In cases of out-of-hospital sudden cardiac arrest, women have significantly better resuscitation rates than men, especially when controlling for age, particularly among women with non-ventricular fibrillation/ventricular tachycardia presentations. Additional studies are required to validate these observations, not only for long-term survival and external validity, but also for other potential genetic factors and potential discrepancies with other studies.

Abstract
OBJECTIVE To investigate the factors which influence decision making by experienced emergency physicians when they decide whether to (a) pronounce 'life extinct' in adult patients with non traumatic cardiac arrest while in the ambulance, or (b) bring them into the resuscitation room in the Emergency Department for further assessment/management. DESIGN Qualitative study involving semi structured interviews and a focus group. SETTING Accident & Emergency (A&E) departments in the Yorkshire region. PARTICIPANTS Fifteen emergency physicians (two clinical fellows, nine specialist registrars and four consultants) working in the Yorkshire region. RESULTS Six main themes were identified that impacted upon the decision making process: the doctor's past experience, ambulance service issues, prehospital care, patient characteristics, presence and views of relatives, and organisational issues. CONCLUSION The reasoning behind decisions made when a patient arrives at the Emergency Department in cardiac arrest is multifactorial. Strict guidelines would be difficult to construct since individuals vary in the importance they attach to different factors.

Abstract
OBJECTIVE To assess whether advanced age is an independent predictor of survival to hospital discharge in community-dwelling adult patients who sustained an out-of-hospital cardiac arrest in a suburban county. METHODS A prospective cohort study was conducted in a suburban county emergency medical services system of community-dwelling adults who had an arrest from a presumed cardiac cause and who received out-of-hospital resuscitative efforts from July 1989 to December 1993. The cohorts were defined by grouping ages by decade: 19-39, 40-49, 50-59, 60-69, 70-79, and 80 or more. The variables measured included age, gender, witnessed arrest, response intervals, location of arrest, documented bystander cardiopulmonary resuscitation, and initial rhythms. The primary outcome was survival to hospital discharge. Results are reported using analysis of variance, chi square, and adjusted odds ratios from a logistic regression model. Age group 50-59 served as the reference group for the regression model. RESULTS Of the 2,608 total presumed cardiac arrests, the overall survival rate to hospital discharge was 7.25%. Patients in age groups 40-49 and 50-59 experienced the best rate of successful resuscitation (10%). Each subsequent decade had a steady decline in successful outcome: 8.1% for ages 60-69; 7.1% for ages 70-79; and 3.3% for age 80+. In a post-hoc analysis, further separation of the older age group revealed a successful outcome in 3.9% of patients ages 80-89 and 1% in patients 90 and older. Patients aged 80 years or more were more likely to arrest at home, were more likely to have an initial bradyasystolic rhythm, yet had a similar rate of resuscitation to hospital admission. In the regression model, age 80 or older was associated with a significantly worse survival to hospital discharge (OR = 0.4, 95% CI = 0.20 to 0.82). CONCLUSIONS There was a twofold decrease in survival following out-of-hospital cardiac arrest to discharge in patients aged 80 or more when compared with the reference group in this suburban county setting. However, resuscitation for community-dwelling elders aged 65-89 is not futile. These data support that out-of-hospital resuscitation of elders up to age 90 years is not associated with a universal dismal outcome.

Abstract
The purpose of this study was to describe the chain of survival in Amsterdam and its surroundings and to suggest areas for improvement. To ensure accurate data, collection was made by research personnel during the resuscitation, according to the Utstein recommendations. Between June 1, 1995 and August 1, 1997 all consecutive cardiac arrests were registered. Patient characteristics, resuscitation characteristics and time intervals were analyzed in relation to survival. From the 1046 arrests with a cardiac etiology and where resuscitation was attempted, 918 cases were not witnessed by EMS personnel. The analysis focussed on these 918 patients of whom 686 (75%) died during resuscitation, 148 (16%) died during hospital admission and 84 patients (9%) survived to hospital discharge. Patient and resuscitation characteristics associated with survival were: age, VF as initial rhythm, witnessed arrest and bystander CPR. EMS arrival time was significantly shorter for survivors (median 9 min) compared to non-survivors (median 11 min). In 151 cases the police was also alerted and arrived 5 min (median) earlier than EMS personnel. Using the OPC/CPC good functional health was observed in 50% of the survivors and moderate performance in 29%. All links in the chain of survival must be strengthened, but equipping the police with semi-automatic defibrillators may be the most useful intervention to improve survival.

Abstract
Sudden cardiac death is one of the leading causes of death and a major public health problem that particularly affects the elderly. Sudden cardiac death may be a terminal event after a prolonged debilitating and painful illness, or it may occur following many years of symptoms related to a cardiac disorder; however, in many elderly persons, the cardiac arrest may be the first manifestation of cardiac disease in a supposedly healthy and physically active person. Whether cardiopulmonary resuscitation should be performed in elderly patients who sustain cardiac arrest is a significant issue confronting the medical profession and the general public. Several questions must be answered when evaluating the decision of whether or not to perform cardiopulmonary resuscitation on an elderly patient.

Abstract
BACKGROUND Though mouth-to-mouth resuscitation (MMR) is widely endorsed as a useful lifesaving technique, studies have shown that health care professionals are reluctant to perform it. To characterize the circumstances which facilitate this reluctance among physicians, we have surveyed current and future residency trainees regarding attitudes toward providing ventilation by this method to strangers experiencing arrest in the community. METHODS A total of 280 categorical emergency medicine (EM) and internal medicine (IM) house officers and respective program applicants at a 655 bed Brooklyn, New York teaching hospital were anonymously surveyed regarding their willingness to attempt resuscitation in five hypothetical scenarios of cardiopulmonary arrest. RESULTS A direct relationship was observed between residency training level and reluctance to perform MMR in each scenario. Applicants expressed greater overall willingness to perform MMR than all residents (56 versus 34%, P < 0.00001). Willingness among experienced residents was lower than for junior-level residents (29 versus 40%, P = 0.01). EM and IM physicians were statistically indifferent in their responses. There were no differences in willingness to perform MMR by age in MD applicant or resident groups. CONCLUSIONS Many physicians and future doctors are reluctant to perform MMR on arrest victims in the community, a trend that increases in prevalence among those with more residency training. These data support the hypothesis that diminished helping behavior occurs gradually over the training period and may occur as a direct consequence of the training experience. A model for characterizing the elements that make up a rescuer's decision process is proposed.

Abstract
Paramedics in Oslo are allowed to make decisions about withholding or terminating cardiopulmonary resuscitation (CPR). In order to elicit the criteria used, 35 paramedics and nine doctors were interviewed after 70 episodes of cardiac arrest outside-of-hospital. CPR was not attempted in 21 patients, and discontinued in the field in 28 patients. Spontaneous circulation was restored in 15 patients, and six patients were transported to hospital with ongoing CPR. Both prognostic and ethical criteria were used without a clear borderline. Signs considered to indicate good prognosis such as VF, gaps, contracted pupils, or normal skin color always led to start of CPR. Bystander CPR was continued even when the professional thought the effort was futile, partly to encourage the bystanders. The social status of the patient did not affect the decisions, and advanced age only when combined with important criteria such as arrest times or the relatives' wishes. The only apparent difference between paramedics and doctors was that the reputation of the EMS system influenced only the paramedics. All paramedics had long experience which influenced their decisions, which were based on a rapidly composed broad picture of the patient's situation. All presented serious ethical considerations about life and death indicating that they did not make these decisions lightly.

Abstract
OBJECTIVES To review the various outcomes from cardiopulmonary resuscitation (CPR), the factors that influence these outcomes, the costs associated with CPR, and the application of cost-analyses to CPR. DATA SOURCES Data used to prepare this article were drawn from published articles and work in progress. STUDY SELECTION Articles were selected for their relevance to the subjects of CPR and cost-analysis by MEDLINE keyword search. DATA EXTRACTION The authors extracted all applicable data from the English literature. DATA SYNTHESIS Cost-analysis studies of CPR programs are limited by the high variation in resources consumed and attribution of cost to these resources. Furthermore, cost projections have not been adjusted to reflect patient-dependent variation in outcome. Variation in the patient's underlying condition, presenting cardiac rhythm, time to provision of definitive CPR, and effective perfusion all influence final outcome and, consequently, influence the cost-effectiveness of CPR programs. Based on cost data from previous studies, preliminary estimates of the cost-effectiveness of CPR programs for all 6-month survivors of a large international multicenter collaborative trial are $406,605.00 per life saved (range $344,314.00 to $966,759.00), and $225,892.00 per quality-adjusted-life-year (range $191,286.00 to $537,088.00). CONCLUSIONS Reported outcome from CPR has varied from reasonable rates of good recovery, including return to full employment to 100% mortality. Appropriate CPR is encouraged, but continued widespread application appears extremely expensive.

Abstract
OBJECTIVE To determine which factors are perceived by senior house officers (SHOs), consultants, and medical registrars in accident and emergency (A&E) medicine as being important in decision making. METHODS 132 SHOs in A&E medicine, of 172 attending an induction course at the start of their job (77%), completed a questionnaire relating to 20 factors of possible importance in decision making; 73 completed the questionnaire at six weeks and 55 at six months. Ten medical registrars and 31 consultants in A&E medicine also completed the questionnaire. RESULTS The SHOs were able to recognise bystander cardiopulmonary resuscitation and early advanced I support, as well as the presence of ventricular fibrillation, as important prognostic factors. There was considerable variation in all three groups in their opinions on the importance of the other factors considered. There was no obvious change in SHO responses over the period of training. CONCLUSIONS Lack of guidelines may result in more patients receiving resuscitation than are salvageable, as doctors maintain a low threshold for continuing resuscitation to avoid missing potential survivors. A decision making algorithm is recommended.

Abstract
The appropriateness of aggressive resuscitation in many clinical settings has been questioned. Survival rates from cardiac arrest in the elderly are generally reported as poor, and satisfactory results from resuscitation attempts prolonged beyond 15 minutes are said to be rare. It was the purpose of this study to examine success rates for resuscitation in a cohort of elderly inpatients suffering cardiac arrest. We retrospectively reviewed 213 consecutive cardiac arrests occurring during a 12-month period in a large tertiary private hospital. Patient age, presenting rhythm, and survival to hospital discharge were recorded. Elderly was defined as 70 years or older. Cardiac arrests in the elderly totaled 89. Average age in this cohort was 76.2 +/- 4.5 years. Eighteen patients (20.2%) had return of spontaneous circulation and 8 patients survived to hospital discharge (44.4% of those with return of spontaneous circulation). No significant difference in age or presenting rhythm of survivors versus nonsurvivors could be demonstrated, although a trend to more frequent ventricular fibrillation or ventricular tachycardia was seen (P = .059, Fisher's exact). Time for resuscitation averaged 25.75 +/- 9.2 minutes for survivors and 32.6 +/- 22.1 minutes for nonsurvivors. Survival to hospital discharge occurs in 9% of in-hospital cardiac arrests in the elderly following average CPR times substantially in excess of 15 minutes.

Abstract
More than 250,000 women will die of cancer in the United States this year, almost 10% of which are due to gynecologic malignancies. Many of these women will have received care in the intensive care unit (ICU). With important advances in medical technology and the advent of an expanded pharmacologic armamentarium, our ability to maintain life has increased greatly over the past few years. However, this phenomenon has been associated with great emotional and financial cost. It is estimated that ICU charges totaled almost 10% of the $810 billion spent on health care in the United States in 1992. Because 6-month survival rates for patients with cancer admitted to an ICU are the lowest of any disease subgroup (23.7%), we must critically evaluate the role of the ICU in the care of these patients. Decisions regarding admission to an ICU, level of care, and termination of care must take into account patient and family wishes, a reasonable estimation of the reversibility of the acute disease process in question, and the natural history of the underlying disease. Many prognostic scoring systems have been devised to estimate the probability of death among adult ICU patients; however, most of these systems were developed with data from trauma patients rather than from patients with an underlying malignancy, and none are capable of predicting which patient will die. Decisions concerning level of care in the ICU will necessarily involve medical as well as ethical considerations and are best made with a team approach.

Abstract
To compare resuscitation outcomes in elderly and younger prehospital cardiac arrest victims, we used a retrospective case series over 5 years in rural advanced life support (ALS) units and a University hospital base station. Participants included 563 adult field resuscitations. Excluded were patients with noncardiac etiologies, those less than 30 years old, and those with unknown initial rhythms. Patients were grouped by age. Return of spontaneous circulation (ROSC) and survival to hospital discharge were compared by Yates' chi-square test. ALS treatment of cardiac arrest was by regional protocols and on-line physician direction. Sixty percent (320/532) of patients were over 65 years old. The proportion with initial rhythm ventricular fibrillation (VF) was 50% in the elderly and 48% in younger patients. ROSC was achieved in 18% of elderly and 16% of younger patients; survival was 4% among the elderly and 5% for younger patients. The oldest survivor was 87 years old. Most survivors were discharged, in good Cerebral Performance Categories. There was no difference in outcome by age group when initial cardiac rhythm was considered. Early cardiopulmonary resuscitation (CPR) and ALS and initial rhythm VF were associated with the best resuscitation success. Age has less effect on resuscitation success than other well-known factors such as early CPR and ALS. Advanced age alone should probably not deter resuscitation attempts.

Abstract
OBJECTIVE To determine whether age is associated with the outcome of cardiopulmonary resuscitation (CPR) in the coronary care unit (CCU). DESIGN Retrospective chart review. SETTING The coronary care units of two Canadian tertiary care teaching hospitals. PATIENTS Two hundred sixty-four coronary care unit patients undergoing cardiopulmonary resuscitation between January 1, 1985 and June 30, 1992. RESULTS There was no significant difference in survival to discharge after CPR between patients less than 70 years of age (17.0%) and patients 70 years of age and older (17.2%) (odds ratio = 0.99; 95% confidence interval = 0.46, 1.80). Patients 70 years of age and older who survived to discharge after CPR had significantly greater lengths of stay (28.1 vs 19.3 days, P = .008). CONCLUSIONS Age was not associated with a difference in survival to discharge after CPR in the CCU, although a clinically significant difference could not be excluded because of limited power.

Abstract
The aim of this study was to describe factors associated with in-hospital mortality among patients being hospitalised after out-of-hospital cardiac arrest and who were found in ventricular fibrillation. The study was set in the community of Göteborg, Sweden. The subjects consisted of all patients who were hospitalised alive after out-of-hospital cardiac arrest, being reached by our mobile coronary care unit and who were found in ventricular fibrillation, between 1981 and 1992. In all, 488 patients fulfilled the inclusion criteria of which 262 (54%) died during initial hospitalization. In a multivariate analysis including age, sex, history of cardiovascular disease, chronic medication prior to arrest and circumstances at the time of arrest, the following appeared as independent predictors of hospital mortality: (1) interval between collapse and first defibrillation (P < 0.001); (2) on chronic medication with diuretics (P < 0.01); (3) age (P < 0.01); (4) bystander initiated CPR (P < 0.05); and (5) a history of diabetes (P < 0.05). In a multivariate analysis considering various aspects of status on admission to hospital, the following were independently associated with death: (1) degree of consciousness (P < 0.001) and (2) systolic blood pressure (P < 0.05). In conclusion, among patients with out of hospital cardiac arrest found in ventricular fibrillation and being hospitalised alive, 54% died in hospital. The in-hospital mortality was related to patient characteristics before the cardiac arrest as well as to factors at the resuscitation itself.

Abstract
OBJECTIVE To assess survival after cardiac arrest and to determine whether age is an independent determinant of late mortality or poor neurologic outcome. DESIGN Analyses using results of Brain Resuscitation Clinical Trial I (1979 to 1984) and Brain Resuscitation Clinical Trial II (1984 to 1989), two randomized, double-blind studies of outcome following cardiac arrest. SETTING A multicenter study in 12 acute care hospitals in nine countries (Brain Resuscitation Clinical Trial I), and 24 hospitals in eight countries (Brain Resuscitation Clinical Trial II). PATIENTS A total of 774 patients who were initially comatose after successful resuscitation from cardiac arrest. The analyses include both in- and out-of-hospital cardiac arrests. RESULTS The 6-month mortality rate for the entire group was 81%. Mortality rate was 94% for the oldest group (> 80 yrs) compared with 68% for the youngest group (< or = 45 yrs) (p < .01). Other independent predictors of mortality were history of diabetes mellitus, inhospital arrests, arrest time of > 5 mins, history of congestive heart failure, a noncardiac cause of arrest, and cardiopulmonary resuscitation time of > 20 mins. Of the 774 patients, 27% recovered good neurologic function. There was no statistically significant difference in neurologic recovery rates by age. Multivariate analysis showed that independent predictors of good neurologic recovery were: no history of diabetes mellitus, a cardiac cause of arrest, short arrest time, and short cardiopulmonary resuscitation time. CONCLUSION Increasing age was a factor in postresuscitation mortality, but was not an independent predictor of poor neurologic outcome.

Abstract
Many patients who receive cardiopulmonary resuscitation (CPR) for cardiac arrest do not survive to leave hospital. Factors associated with adverse outcomes include unwitnessed cardiac arrest in general wards, particularly at night, prolonged resuscitation, asystole, associated disorders (e.g. sepsis, malignancy, renal failure, and left ventricular dysfunction), absent pupillary responses, hypoxaemia, low PetCO2 during resuscitation, and severe acid base imbalance. Outside hospitals, cardiac arrests result in more favourable outcomes if they occur at work, and bystander CPR and early defibrillation are initiated. On admission to ICU, likely predictors of death or severe neurological disability include prolonged coma, impaired brainstem reflexes, and persistent convulsions. Experience with cerebrospinal fluid enzymes and electrophysiological measurements is limited. Multivariate scoring systems are not sufficiently reliable. The importance of hyperglycaemia, the required level of CPR training, and the appropriateness of responding to some cases, remain debatable.

Abstract
BACKGROUND The rising healthcare costs and the ethical and economic implications of cardiopulmonary resuscitation (CPR) have generated interest in defining criteria to predict the appropriateness of CPR in specific patients. Age has been proposed as one such a criterion. METHODS As part of a quality assurance program, all instances of CPR (code-500) at our VA Medical Center were prospectively studied over a period of 45 months. Only events in noncritical care hospital areas were included in this analysis. The CPR data were prospectively collected, and follow-up of initial survivors was continued until the end of the study period or until a patient died. RESULTS Of a total of 422 code-500 events, 387 (92 percent) met our study definition of cardiorespiratory arrest, and 255 of these occurred in a noncritical care area and were included in the study. Our immediate survival was 52 percent (n = 132), survival after intensive care unit (ICU) stay was 22 percent (n = 55), survival to hospital discharge was 11 percent (n = 28), and 4 percent of the patients (n = 10) were alive at the end of follow-up (mean, 22 months). None of the patients discharged alive had a significant new neurologic deficit, and all but one returned to their preadmission environment. The post-CPR hospital charges for each of the surviving patients was estimated at $63,000. Age, the admitting diagnosis, and main comorbidity did not predict long-term survival. The post-CPR Apache II score correlated with a patient surviving the ICU stay, but did not correlate with long-term survival either. CONCLUSIONS Age alone is not a valid criterion to decide whether a patient is a suitable candidate for CPR, and the principal diagnosis and main comorbidity at the time of admission do not appear to predict long-term survival either. Whether in-hospital CPR in noncritical care areas is cost-effective is an issue that society at large must eventually decide.

Abstract
The bioethical issues confronting the Jewish chaplain in a long-term care facility are critical, particularly as life-support systems become more sophisticated and advance directives become more commonplace. May an elderly competent patient refuse CPR in advance if it is perceived as a life-prolonging measure? May a physician withhold CPR or artificial nutrition and hydration (which some view as basic care and not as therapeutic intervention) from terminal patients with irreversible illnesses? In this study of Jewish ethics relating to these issues, the author carefully examines the moral implications and legal precedents in the literature. Jewish ethics, affirming a 'sanctity of life' position, suggest that while an elderly person may direct in advance that CPR not be administered in most instances, in the absence of a DNR (Do Not Resuscitate) order, CPR must be performed. In reference to 'tube-feeding', while there is some debate about whether elderly patients may refuse the initiation of 'tube-feeding', there is a consensus that once initiated, it may not be withdrawn.

Abstract
BACKGROUND Studies suggest that a majority of elderly patients would want to undergo cardiopulmonary resuscitation (CPR) if they had a cardiac arrest. Yet few studies have examined their preferences after clinicians have informed them about the outcomes of CPR. METHODS To study older patients' preferences regarding CPR, we interviewed as many ambulatory patients as possible in one geriatrics practice in Denver from August 1, 1991, through July 31, 1992. RESULTS A total of 371 patients at least 60 years of age were eligible; 287 completed the interview (mean age, 77 years; range, 60 to 99). When asked about their wishes if they had cardiac arrest during an acute illness, 41 percent opted for CPR before learning the probability of survival to discharge. After learning the probability of survival (10 to 17 percent), 22 percent opted for CPR. Only 6 percent of patients 86 years of age or older opted for CPR under these conditions. When asked about a chronic illness in which the life expectancy was less than one year, 11 percent of the 287 patients opted for CPR before learning the probability of survival to discharge. After learning the probability of survival (0 to 5 percent), 5 percent said they would want CPR. CONCLUSIONS Older patients readily understand prognostic information, which influences their preferences with respect to CPR. Most do not want to undergo CPR once a clinician explains the probability of survival after the procedure.

Abstract
OBJECTIVE To compare the clinical characteristics and survival of elderly and younger hospitalized patients who sustain cardiac arrest and receive cardiopulmonary resuscitation (CPR) in the 1990's and to assess predictors of survival. DESIGN Retrospective survey of cardiac arrest database and hospital charts, plus telephone follow-up. SETTING 450-bed acute care teaching hospital. STUDY POPULATION Seventy-eight hospitalized patients 70 years or older and 73 hospitalized patients under 70 years of age. MEASUREMENTS Survey of cardiac arrest data base, hospital charts, and telephonic follow-up to allow (1) comparison of clinical characteristics, survival, and long-term follow-up between two age groups and (2) univariate and multivariate analysis of predictors of mortality. MAIN RESULTS Pre-arrest clinical characteristics were not significantly different between the age groups. Prior to arrest the majority of patients were functionally active, and over one-third were hospitalized for acute coronary artery syndromes. In approximately 85% of the patients, the arrest was witnessed, and 70% of the patients had their cardiac rhythm monitored at onset of the arrest. Survival was not significantly different between the age groups; 26% of the total 151 patients were discharged. No significant difference was noted in pre-post arrest functional status of survivors. Survival at 1, 2, and 3 years in elderly and younger survivors was 86% versus 80%, 76% versus 67%, and 71% versus 61%, respectively. Multivariate analysis identified the presence of coronary artery disease, admission systolic blood pressure, and functional level to be independent pre-arrest predictors of mortality. At the time of the arrest, the initial cardiac rhythm and duration of CPR were found to be independent predictors of mortality. CONCLUSIONS Elderly patients hospitalized in the 1990's who receive CPR have outcomes similar to younger patients who receive CPR. The favorable outcome in the elderly patients may reflect patient selection: the majority of our patients were functionally active prior to hospitalization, without multiple serious illnesses; many were hospitalized for acute coronary artery syndromes; and, in most cases, the arrest was witnessed with the patient's cardiac rhythm monitored at onset of the arrest.

Abstract
PURPOSE To determine the benefits of cardiopulmonary resuscitation (CPR) in nursing home patients and assess possible prearrest and arrest predictors of survival. PATIENTS AND METHODS During a 4-year period (1986 to 1989), consecutive nursing home patients from Milwaukee, Wisconsin, who sustained cardiac arrest and received CPR by paramedics were studied. The patients' prearrest clinical characteristics were determined including age, length of stay in nursing home, medical diagnoses, medications, circumstances surrounding the arrest, laboratory studies, and baseline functional status. Cardiac arrest data were obtained from a paramedic computer data base and included whether the arrest was witnessed, initial cardiac rhythm, and success of CPR. Survival was defined as the discharge of the patient alive from the hospital, and the patient's pre- and post-arrest functional status was compared. Possible predictors of survival were analyzed from the patient's prearrest characteristics and arrest characteristics. RESULTS Of the total 196 patients who received CPR, 37 (19%) were successfully resuscitated and hospitalized, and 10 (5%) survived to be discharged. However, 27% of patients survived whose arrests were witnessed and who demonstrated ventricular fibrillation at the time of the arrest. In comparison, only 2.3% of all other nursing home patients who received CPR survived (p < 0.0002). Age, mental or functional status, hematocrit, renal dysfunction, pulmonary disease, cancer, and cardiovascular disease were not significant predictors of survival. At the time of hospital discharge, the functional status of the majority (80%) of the survivors was comparable to their prearrest status and 40% of the survivors lived for greater than 12 months. CONCLUSION We conclude that only a small percentage of nursing home patients who sustain cardiac arrest will benefit from CPR. However, greater than 25% of nursing home patients whose arrest is witnessed and who demonstrate ventricular fibrillation will survive. This is comparable to the survival rate of elderly community-dwelling persons who sustain cardiac arrest. Our data suggest that CPR should be initiated only in nursing home patients whose cardiac arrest is witnessed and should only be continued in patients whose initial documented cardiac rhythm is ventricular fibrillation or ventricular tachycardia.

Abstract
Defibrillation of patients with primary ventricular fibrillation (VF) results in a variety of rhythm changes. We analysed these changes in rhythm in 200 patients, using the American Heart Association's recommendation of two defibrillations prior to drug therapy. Sixty-three (31.5%) patients were immediate survivors with 38 (19%) being discharged from hospital alive. There was no difference between the age of immediate survivors (66.5 years, S.D. = 11.2) and non-survivors (68.3 years, S.D. = 13.7, P = 0.37). Immediate survivors were significantly more likely to be discharged alive from hospital if they were younger (70.0 years, S.D. 8.5 vs. 62.1 years, S.D. 15.8, P = 0.014). Increasing delays to the initiation of basic life support (CPR) and to defibrillation were associated with significantly less likelihood of cardioversion to sinus rhythm (P < 0.005 and P < 0.002, respectively). Those patients who stayed in VF were not more likely to be defibrillated into asystole or electro-mechanical dissociation. Seventeen percent (34) of patients were defibrillated to sinus rhythm after the first defibrillation and 14% (19) after the second, with similar hospital discharge rates (62% and 58%, respectively). Sixty percent (32) of patients in sinus rhythm, after two defibrillations, were discharged alive, compared to only 4% (6) of those patients not in sinus rhythm after two defibrillations. Our data provide new information on rhythm changes during resuscitation and supports the need for the earliest possible initiation of basic life support and defibrillation to improve survival from cardiac arrest due to ventricular fibrillation.

Abstract
OBJECTIVE To determine the rate of cardiopulmonary resuscitation use among all nursing homes in a large urban area, to examine CPR use over time, to discover whether CPR use varies among nursing homes, and to describe characteristics of patients undergoing CPR. DESIGN Retrospective survey. SETTING Nursing homes in a large urban area. PARTICIPANTS One hundred ninety-six nursing home residents of 68 nursing homes underwent cardiopulmonary resuscitation over a 4-year period (1986-1989). Over this time there were 9,486 deaths in these homes, which comprised 10,252 beds. MEASUREMENTS The CPR:death ratio was determined for each facility. The ratio was analyzed over time and by type of facility (eg, proprietary, non-profit, size of facility). The ratio was also examined among facilities with variable death rates. Patients undergoing CPR are described. RESULTS The ratio of CPR:death over the 4-year period was 0.02. CPR:death ratio was higher (0.03) for the proprietary homes compared with the non-profit homes (0.01) P < 0.0001. A significant downward trend of CPR:death was noted over the study period for the non-profit homes; no such trend was noted in the proprietary homes. Size of nursing home did not influence the rate of CPR use. Homes with greater numbers of deaths per bed had a lower utilization of CPR. Patients undergoing CPR were old, frail, and had multiple medical problems. CPR attempts were frequent around the time of nursing home admission. CONCLUSION The utilization of CPR in nursing homes is quite low. Non-profit homes utilize CPR less than proprietary homes. Nursing homes with the highest numbers of deaths per bed utilize CPR less than homes with lower numbers of deaths per bed. Nursing home residents receiving CPR are quite old, have multiple illnesses, and are impaired.

Abstract
Without a well-functioning, prehospital, do-not-resuscitate (DNR) system in place, emergency medical service (EMS) providers must resuscitate all patients who access the system, regardless of the patients' wishes and regardless of what makes ethical or economic sense. In lieu of valid documentation, it is not appropriate to withhold resuscitative measures in this critical, time-dependent situation. In order to help EMS systems implement functional prehospital DNR protocols, this paper reviews the state-of-the-art of prehospital DNR including the issues to consider when designing such a system and a discussion of the features of some of the existing systems. This review includes: 1) the basis and requirements of a DNR system; 2) legal and physical forms for DNR orders; 3) eligibility for DNR status; 4) reversal of DNR orders; and 5) inappropriate use of EMS systems for DNR patients. Finally, a more general discussion of overall resource utilization in prehospital resuscitations is presented to emphasize that implementing prehospital DNR systems is only one piece of a larger issue.
