Cardiopulmonary resuscitation in elderly patients hospitalized in the 1990s: a favorable outcome.

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.

Utilization of cardiopulmonary resuscitation in nursing homes in one community: rates and nursing home characteristics.

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.

The precordial thump.

The American Heart Association (AHA) currently recommends the precordial thump as the initial maneuver in treatment of ventricular tachycardia (VT) and monitored ventricular fibrillation (VF). These recommendations are based largely on anecdotal reports of successful "thump-version" of asystole, VF, and VT. The Milwaukee County Paramedic System follows the AHA guidelines in the treatment of VT and VF. The precordial thump is included in the advanced cardiac life support (ACLS) paramedic training program, and has been used in our approach to the pulseless, nonbreathing patient. During an eight-month period, 50 pulseless, nonbreathing patients received precordial thumps during ACLS resuscitative attempts. Twenty-seven patients who developed monitored VT and 23 patients with monitored VF were thumped. Three of 27 patients (11%) with VT were thumped into a supraventricular rhythm, 12 of 27 patients (44%) remained in VT, and 12 of 27 patients were thumped from VT into more malignant rhythms: three, into asystole; eight, into VF; and one, into an idioventricular/electromechanical dissociation rhythm. A total of 23 patients were thumped without effect. Subsequently, using countershock and medications, 12 of these 23 patients were successfully resuscitated. In the prehospital setting the precordial thump is usually not beneficial, and may be detrimental. Thus its use as the initial maneuver in treating the cardiac arrest patient with VT or VF in this setting cannot be supported. The presence of acidosis and hypoxia may explain why prehospital precordial thump responses differ from those seen in the hospital environment.

Evaluation of the systolic murmur in the elderly.

A common clinical entity in the elderly population is the systolic murmur detected during cardiac auscultation. Although it can occur in patients of any age group, the approach to diagnosis differs in the elderly. Two cases are presented which illustrate different pathologic processes that can result in the development of a systolic murmur. The prevalence of this entity in the elderly is highlighted, and a strategy for diagnosis is outlined.
