The misuse of cardiopulmonary resuscitation

Over a 41-month period, 1,233 "Code Blues" were retrospectively reviewed. Twenty-five codes on infants and children < 16 years of age were eliminated from the study group. The adult survivors of 1,208 codes numbered 243 (20.1%). Clinical chart review revealed that 49 (4.0%) did not involve cardiopulmonary resuscitation (CPR) or intubation and were "non-codes." Of the remaining 1,159 codes, there were 194 (16.7%) survivors. Of these survivors, 102 (52.5%) were patients with respiratory distress or failure and required intubation only. No CPR was needed. Thus, only the remaining 92 survivors of the 1,057 codes were cardiac cases for which CPR was appropriate (8.7% survival). Ventricular tachycardia and fibrillation, promptly defibrillated, was the most important rhythm factor for survival. Underlying ischemic heart disease (acute myocardial infarction and chronic ischemic heart disease with arrhythmia) was the most common underlying disease entity among the survivors. CPR performed in the group of patients unlikely to survive was expensive.     

The effects of preoperative therapy with angiotensin-converting enzyme inhibitors on clinical outcome after cardiovascular surgery

PURPOSE: Quality of life of breast cancer survivors 8 years after diagnosis was compared with that among similarly aged women who had never confronted cancer (controls). METHODS: Survivors of a consecutive series of 227 breast cancer patients first treated in 1984 were approached for this study. Random-digit dialing was used to identify controls with the same age and residential distribution as the survivors. Quality of life was assessed in terms of physical health, functional status, psychologic distress, and social functioning. RESULTS: Participation was obtained from 96% (n = 124) of 129 eligible survivors and 61% (n = 262) of 427 potentially eligible controls. Consistently smaller proportions of survivors reported positive quality-of-life outcomes compared with controls, but these differences were generally small and nonsignificant statistically. When limited to women who remained free of disease over the entire follow-up period (n = 98), survivors' quality of life was similar to that among controls, with the exception of arm problems and sexual satisfaction for those women who lived with a partner. In contrast, survivors who developed recurrence or new primary breast cancer (n = 26) experienced a worse quality of life in all domains except social functioning. CONCLUSION: In most domains and for women without further disease events after diagnosis, quality of life does not seem to be permanently and globally impaired by breast cancer. Consequently, breast cancer survivors who remain free of disease probably do not need organized late psychosocial follow-up to improve quality of life. However, arm problems and sexuality are two areas in which additional effort may be still needed to improve quality of life of long-term survivors.     

Factors influencing CPR outcome in Siriraj Hospital

This prospective study of cardiopulmonary resuscitation was surveyed in Siriraj Hospital from 1 March 1996 to 31 May 1996. In a 3-month-period, 94 resuscitated patients were reported with initial survivors 31 cases (33%) and 3 patients (3%) were alive until discharged from the hospital. Most of the resuscitated patients belonged to the emergency department (47%) with the lowest survival rate (23%). The common causes of cardiac arrest were heart diseases (31%) and respiratory failure (21%). All survivors who were able to be discharged from the hospital had suffered cardiac arrest from heart diseases. After resuscitation, only half of the initial survivors received postarrest care in the intensive care units, the rest remained in general wards and outpatient department. By using logistic regression for multivariate analysis, the survival rate was correlated with locations of CPR, duration of CPR and duration of attempt endotracheal intubation. The initial survival outcome of CPR was not related to sex, age, time of day of CPR, duration of hospitalization before CPR, types of arrhythmia, delay in doctors' arrival and performers of CPR.     

Quality of life following spinal cord injury: knowledge and attitudes of emergency care providers

STUDY OBJECTIVES: To measure emergency care providers' attitudes toward quality of life after spinal cord injury (SCI) and to determine if their perceptions influence the care they provide. DESIGN: A closed-ended questionnaire. SETTING AND PARTICIPANTS: Two hundred thirty-three emergency nurses, emergency medicine technicians, emergency medicine residents, and attending physicians at three level I trauma centers were surveyed. Their responses were compared with previously reported quality-of-life ratings of a group of 128 high-level SCI survivors. MEASUREMENTS AND RESULTS: One hundred fifty-three emergency care providers completed the survey (response rate, 63%). Forty-one percent believed that resuscitation efforts after severe SCI are too aggressive, and 28% believed that future quality of life should be a factor in determining the interventions that should be provided. If they sustained severe SCIs themselves, 22% of providers would want nothing done to ensure their survival, and 23% would want pain relief only. Only 18% imagined they would be glad to be alive with a severe SCI, compared with 92% of a true SCI comparison group. Seventeen percent of providers anticipated an average or better quality of life compared with 86% of the actual SCI comparison group. CONCLUSION: The quality of life, self-esteem, and outcomes that emergency health care providers imaging after SCI are considerably more negative than those reported by SCI survivors. Because providers' knowledge and attitudes may affect the care they provide and may influence patients and families struggling with critical treatment decisions, emergency care providers must be aware of outcomes, well-being, and life satisfaction following severe SCI.     

Properties of recombinant bacteriophage T4 tail sheath protein and its deletion fragments

We aimed to determine whether our results were any better or worse than other published reports and to examine the efficacy of the West Midlands Ambulance Service (WMAS) policy of applying cardiopulmonary resuscitation (CPR) and manual ventilation to all unwitnessed cardiac arrests in preference to immediate defibrillation. All cardiac arrests were studied from October 1994 to September 1996. In all unwitnessed arrests, crews undertook CPR and manually ventilated the lungs via a mask or an endotracheal tube with a bag and valve or a mechanical resuscitator using an FIO2 of 1 or 0.21 for at least 2 min before defibrillation was attempted. There were 3403 diagnosed cardiac arrests but, in these, the diagnosis was not certain. CPR and advanced life support (ALS) were applied in 3380 patients and return of spontaneous circulation (ROSC) was obtained in 554, giving a success rate of 16.4%. A total of 364 patients were accepted into hospital, 90 patients died in A&E but 274 patients were admitted to ICU/CCU. Seventy died within 24 h, 69 died after 24 h and 135 were discharged alive and well without cerebral damage. The final success to discharge rate was 49.27%. Of those discharged, 69 had a circulatory arrest period of more than 4 min but in only 10 was a bystander available to start CPR. The European Resuscitation Council Guidelines recommending immediate defibrillation for unwitnessed arrests are not supported by these results. The apparent lack of cerebral damage and the percentage success suggests that resuscitation considerations should be as brain orientated as they are heart orientated. The elapsed time periods reported challenge several shibboleths.     

Documenting life-support preferences in hospitalized patients

PURPOSE: The purpose of this article was to determine the extent to which patients at high risk of hospital death who undergo cardiopulmonary resuscitation (CPR) have previously had their life support preferences addressed and documented. MATERIALS AND METHODS: We conducted a retrospective chart review of all patients older than 18 years of age hospitalized for more than 24 hours who sustained a cardiac arrest with attempted CPR at our tertiary care university teaching hospital during 1994 (n = 71). We searched all hospital charts specifying ICD-9 codes: Cardiac arrest, ventricular fibrillation, ventricular tachycardia, asystole, electromechanical dissociation, defibrillation, or CPR. Patients were selected if (1) they had a true cardiac arrest (abrupt cessation of spontaneous circulation) and (2) had attempted CPR or defibrillation. Patients were classified as "high risk" if they satisfied at least one of the following: modified prearrest morbidity index > or = 7, moderate/severe dementia, day 1 APACHE II score > 24 or > or = 4 dysfunctional organ systems. RESULTS: We searched 147 charts; of 71 patients meeting inclusion criteria, 53 were high risk. Of patients at high risk of sustaining a cardiopulmonary arrest during the index hospital admission, 3 (6%) had preferences addressed within the first 24 hours of hospitalization, 7 (13%) had delayed discussion of preferences before arrest, 23 (43%) had preferences addressed post arrest, and 20 (38%) had no documented discussions. Of the 23 high-risk patients initially surviving cardiac arrest, all were subsequently given "do not resuscitate" orders. Univariate analysis of factors associated with life-support discussion before cardiac arrest were previous cardiac arrest (OR, 5.9) and APACHE II score > 24 (OR, 1.1), although neither reached statistical significance. None of the 32 patients with a modified PAM index > or = 7 (32 of 71) survived hospitalization. Only 3 patients survived to hospital discharge. CONCLUSIONS: Early communication regarding life-support preferences is important in high-risk patients so that inappropriate or unwanted treatment is not implemented. Given that optimal care includes addressing and documenting life-support preferences in high-risk patients early in their hospitalization, this standard was infrequently met.     

Pain and quality of life following radical retropubic prostatectomy

PURPOSE: We assess pain and quality of life following radical retropubic prostatectomy and determine whether intraoperative anesthetic management has any long-term effects on outcomes. MATERIALS AND METHODS: A total of 110 patients undergoing radical retropubic prostatectomy were randomly assigned to receive epidural and/or general anesthesia. Patients responded to a questionnaire mailed 3 and 6 months following surgery that assessed prostate symptoms, pain related to surgery, quality of life and mood. RESULTS: No long-term effects of anesthesia were observed. Of the 103 respondents (94%) at 3 months 49% had some pain related to surgery. Although pain was not related to anesthesic technique, patients who had it at 3 months used significantly more pain medication on postoperative day 3. Pain at 3 months was mild, averaging 1.5 on a scale of 0 to 10, and associated with poor perceptions of overall health (p <0.02), and reduced physical (p <0.01) and social (p <0.01) functioning. Pain at 3 months was associated with higher levels of preoperative anxiety (p <0.05). At 6 months 36 of 90 patients (35%) had some pain related to surgery and the impact was similar. CONCLUSIONS: Long-term effects of intraoperative anesthesic technique were not apparent. Mild pain following radical retropubic prostatectomy was common and associated with reduced quality of life, particularly social functioning. Affective distress, particularly anxiety, before surgery and use of pain medications following surgery may be predictors of chronic pain following radical retropubic prostatectomy.     

Outcomes of acute exacerbation of severe congestive heart failure: quality of life, resource use, and survival. SUPPORT Investigators. The Study to Understand Prognosis and Preferences for Outcomes and Risks of Treatments

BACKGROUND: Congestive heart failure (CHF) is a common disease with high health care costs and high mortality rates. Knowledge of the health-related quality of life outcomes of CHF may guide decision making and be useful in assessing new therapies for this population. METHODS: A prospective cohort study was conducted involving 1390 adult patients hospitalized with an acute exacerbation of severe CHF (New York Heart Association class III-IV). Demographic data and health-related quality of life were determined by interview; physiologic status and cost and intensity of care were determined from hospital charts. RESULTS: The median (25th, 75th percentiles) age of patients was 68.0 (58.2, 76.9) years; 61.7% were male. Survival was 93.4% at discharge from the index hospitalization, 72.9% at 180 days, and 61.5% at 1 year. Of patients interviewed at 180 days, the median health rating on a scale of 0 to 100 (0 indicates death; 100, excellent health) was 60 (interquartile range, 50-80), and 59.7% were independent in their activities of daily living. Overall quality of life was reported to be good, very good, or excellent in 58.2% at 180 days. Patients with worse functional capacity were more likely to die. Health perceptions among the patients with available interview data improved at 60 and 180 days after acute exacerbation of severe CHF. CONCLUSIONS: Patients hospitalized for acute exacerbation of severe CHF have a generally poor 6-month survival, but survivors retain relatively good functional status and have good health perceptions. Furthermore, health perceptions improve after the acute exacerbation.     

Pain, depression, and physical functioning following burn injury.

Objective: Little is known about how pain and depression after burn injury may influence long-term outcomes such as physical functioning. This prospective study examined associations between pain, depression, and physical functioning in a sample of burn injury survivors. Design and Participants: Questionnaires assessing pain, depression, and physical functioning were completed by 64 (52% of original sample) adult burn survivors shortly after discharge from burn care and at 1- and 2-year follow-ups. Results: Pain and physical functioning improved over the 2 years of the study, whereas depression levels were stable. Pain and depression were associated with poorer physical functioning over time, but associations varied according to the time span under consideration. Also, the association between pain and physical functioning was strongest among persons with higher depression scores. Conclusions: Pain and depression may contribute independently to compromises in physical functioning. The co-occurrence of pain and depression represents even greater risk for reduced physical functioning over time among burn survivors.

Long-term outcomes in open pelvic fractures

BACKGROUND: Open pelvic fractures represent one of the most devastating injuries in orthopedic trauma. The purpose of this study was to document the injury characteristics, complications, mortality, and long-term, health-related quality of life outcomes in patients with open pelvic fractures. METHODS: The trauma registry at an adult trauma center was used to identify all multiple system blunt trauma patients with a pelvic fracture from January of 1987 to August of 1995 (n = 1,179). Demographic data, mechanism of injury, and fracture type were determined from hospital records. Short-term outcome measures included infectious complications, mortality, and length of stay in hospital. Long-term outcomes of survivors were obtained by telephone interview using the SF-36 Health Survey and the Functional Independence Measure. RESULTS: Open pelvic fractures were uncommon, occurring in 44 patients (4%). Patients with open fractures were about 9 years younger, on average, than patients with closed fractures (30 vs. 39, p < 0.001). Similarly, patients with open fractures were more likely to be male (75 vs. 57%, p < 0.02), more likely to have been involved in a motorcycle crash (27 vs. 6%, p < 0.001), and more likely to have an unstable pelvic ring disruption (45 vs. 25%, p < 0.001). Open pelvic fracture patients required more blood than closed pelvic fracture patients, both in the first day (16 vs. 4 units, p < 0.001) and during the total hospital admission (29 vs. 9 units, p < 0.001). Five patients with perineal wounds did not receive a diverting colostomy; in turn, these individuals had a total of six pelvic infectious complications (one abscess, two with osteomyelitis, and three perineal wound infections). Overall, 11 patients died, six patients were lost to follow-up, and 27 were long-term survivors (mean duration of 4 years). Chronic disability was common after a pelvic fracture, with problems related to physical role performance and physical functioning, and was particularly severe after an open pelvic fracture (p < 0.05 for both as measured by the SF-36). CONCLUSIONS: Patients with open pelvic fractures often survive, need to be treated with massive blood transfusions, and often require a colostomy. They are frequently left with chronic pain and residual disabilities in physical functioning and physical roles, and many remain unemployed years after injury.     

Do not resuscitate: an ethical dilemma for the decision-maker

Since its introduction in the 1960s, cardiopulmonary resuscitation (CPR) has been universally available to all hospital patients unless the consultant in charge has specified a 'do not resuscitate' (DNR) order. The public perception of CPR has tended to be one of overoptimism, but this is not matched by the low survival to discharge ratio of approximately 1:10. In addition, there is the risk of prolonging suffering, compared with the quick and relatively painfree alternative offered by cardiac arrest. Decisions about resuscitation pose many ethical dilemmas for those involved and should take into consideration the patient's wishes, prognosis and quality of life.     

Discriminability in length of lines in the Müller-Lyer figure

OBJECTIVE: To compare patients' health-related quality of life after systemic methotrexate therapy versus laparoscopic salpingostomy for tubal pregnancy. DESIGN: Multicenter randomized clinical trial. SETTING: Departments of obstetrics and gynecology of six Dutch hospitals. PATIENT(S): Hemodynamically stable patients with a laparoscopically confirmed unruptured tubal pregnancy without signs of active bleeding, who were randomly assigned to undergo either systemic methotrexate therapy or laparoscopic salpingostomy. INTERVENTION(S): Standard health-related quality of life questionnaires administered before and 2 days, 2 weeks, 4 weeks. and 16 weeks after confirmative laparoscopy. MAIN OUTCOME MEASURE(S): Health-related quality of life. RESULT(S): Health-related quality of life was impaired most severely 2 days after confirmative laparoscopy in both treatment groups and improved during follow-up. Health-related quality of life was impaired more severely after systemic methotrexate therapy than after laparoscopic salpingostomy. Medically treated patients had more limitations in physical functioning, role functioning, and social functioning; had worse health perceptions, less energy, more pain, more physical symptoms, and a worse overall quality of life; and were more depressed than surgically treated patients. CONCLUSION(S): Systemic methotrexate therapy had a more negative impact on patients' health-related quality of life than did laparoscopic salpingostomy. This negative impact on patients' health-related quality of life of systemic methotrexate therapy should be taken into account when deciding on the appropriate therapy for tubal pregnancy.     

Recovery after allogeneic marrow transplantation: prospective study of predictors of long-term physical and psychosocial functioning

No prospective data have documented the physical and psychosocial functioning of patients before and after BMT. In this study 67 allogeneic transplant patients completed standardized self-report measures pre-transplant. Survivors were re-assessed at 90 days (n = 34) and 1 year (n = 31) post-transplant. Telephone interviews established 4-year work history and performance status. Physical function was most impaired at 90 days post-transplant, with a return to pre-transplant levels of functioning by 1 year in most areas. By 2 years post-transplant, 68% of patients had returned to full-time work. Only 9% of 4-year survivors failed to return to full-time occupations. Mean levels of anxiety and depression did not change over the first year. Pre-transplant, 27% of patients reported depression and 41% reported elevated anxiety. Greater emotional distress at 1 year was predicted by pre-transplant family conflict, non-married status and development of less severe chronic GVHD. Impaired physical recovery at 1 year was predicted by more severe chronic GVHD, pre-transplant physical impairment and family conflict. The large majority of long-term survivors returned to full-time employment with normal physical and psychosocial functioning, although recovery took longer than 1 year for approximately 40%. Family relationships were important determinants of physical and emotional recovery.     

Preexisting dementia in stroke patients. Baseline frequency, associated factors, and outcome

BACKGROUND AND PURPOSE: The link between stroke and degenerative dementia, especially Alzheimer's disease, is closer than expected by chance. Dementia after stroke may be due to the cumulative effect of vascular and degenerative changes. The prevalence of dementia just before stroke onset remains unsettled. The aim of this study was to determine the frequency of preexisting dementia in stroke patients, associated factors, and consequences on outcome. METHODS: We evaluated the cognitive functioning prior to stroke in 202 consecutive patients with ischemic or hemorrhagic stroke by means of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). We classified in the dementia group patients with IQCODE scores of 104 or more. Six months after stroke onset, survivors underwent a battery of neuropsychological tests. RESULTS: Thirty-three patients were demented before stroke (16.3%; 95% confidence interval, 11.2 to 21.4). There was no diagnosis of dementia in 32 of these 33 patients. We determined by logistic regression analysis that female sex, family dementia, leukoaraiosis, and cerebral atrophy are independently associated with prestroke dementia. All survivors who had IQCODE scores of 104 or more at the acute stage met criteria for dementia 6 months later. CONCLUSIONS: Our study showed that one sixth of stroke patients have preexisting dementia. Therefore, some patients with so-called "poststroke dementia" probably had unrecognized preexisting dementia.     

Advance directives and other medical decisions concerning the end of life in cancer patients in Japan

The purpose of our survey was to investigate the experience of physicians regarding advance directives and other medical decisions concerning the end of life. A postal questionnaire was sent to 500 Japanese physicians who were most involved in medical care of terminal patients. A total of 339 (68%) physicians responded. In dealing with terminal patients, approximately half gave priority to their patients' wishes for medical care, if known, regardless of the patient's competency. Of the respondents, 149 had been presented with advance directives by their patients and 35% followed all advance directives presented in their practice. Cardiopulmonary resuscitation (CPR) for arrested patients to enable their family to be at the bedside at the time of the death was common. More than 60% of the respondents thought that active euthanasia and assisted suicide were never ethically justified. Our study indicates that the wishes of patients are currently not always given top priority in medical decisions concerning the end of life.     

Mortality in burned children with acute renal failure

BACKGROUND: During the past 13 years, mortality from acute renal failure in burned children has been on the decline. OBJECTIVE: To determine which new burn therapies contributed to the decrease in mortality. DESIGN: The medical records of burned children admitted from February 1966 to January 1997 were reviewed, and the outcome of changes in the treatment of burned children were compared. PATIENTS AND METHODS: Sixty children with acute renal failure were identified. These children were divided into those admitted from 1966 to 1983 (n=24) and those admitted from 1984 to 1997 (n=36). They were compared with matched control subjects from the same period without renal failure. Values are presented as means+/-SEMs. Statistical analysis was by the Student t test or chi2 analysis. RESULTS: Mortality rates in burned children with acute renal failure decreased from 100% before 1983 to 56% after 1984 (P<.001). The time between a burn injury and the initiation of intravenous fluid resuscitation was 8.6+/-1.7 hours before 1983 compared with 3.0+/-0.5 hours after 1984 (P<.005). The time between a burn injury and complete early wound excision decreased from 228+/-37 hours before 1983 to 40+/-7 hours after 1984 (P<.001). The incidence of sepsis decreased from 71% to 44% in these periods (P<.05). After 1984, survivors had a shorter time delay for fluid resuscitation than nonsurvivors (1.7+/-0.5 hours vs 4.8+/-0.9 hours; P<.005) and a lower incidence of sepsis (19% vs 60%; P<.05). From 1984 to 1997, burned children with acute renal failure who did not require dialysis had significantly shorter delays for fluid resuscitation (2.2+/-0.5 hours vs 4.4+/-0.9 hours) and complete wound excision (29+/-6 hours vs 49+/-7 hours) compared with those requiring dialysis (P<.05 for both). CONCLUSION: Early adequate fluid resuscitation, early wound excision, and better infection control may reduce mortality in burned children with acute renal failure.     

Adverse perinatal outcomes in young adolescents

BACKGROUND: Identification of psychiatric patients with severe and persisting impairments can facilitate treatment, aid in program planning, and provide data for cost-of-care projections. METHODS: In this prospective study of patient outcomes, 1,679 inpatients were classified on admission using a functional status measure developed by the authors. Consenting subjects were reassessed at discharge and at 3, 6, and 12 months postdischarge to determine what proportion of patients classified as low functioning on admission remained so at follow-up. RESULTS: Patients classified as low functioning on admission represented 23.4% of the sample; the proportion that remained low functioning at the follow-ups ranged from 56.1% to 65.2%. Compared to the high functioning group, three times more low functioning patients were rehospitalized within 12 months of discharge (9.4% vs 32%). CONCLUSIONS: Patients with increased risk of persisting disability can be identified on admission using commonly available clinical measures. Of patients with low functioning on admission, more than half will have long-term impairment.     

Life values, resuscitation preferences, and the applicability of living wills in an older population

OBJECTIVES: To determine whether life values are related to resuscitation preferences and living will completion in an older population and to assess beliefs about the applicability of living wills. DESIGN: Individual structured interviews. SETTING: An independent retirement community. PARTICIPANTS: One hundred thirty-two subjects older than 63 years of age. MEASUREMENTS: Resuscitation preferences were elicited in five hypothetical scenarios. Subjects with living wills were asked whether their living will would play a role in the scenarios. Subjects rated the importance of 13 life value statements. RESULTS: The percentage of subjects desiring CPR in each scenario was as follows: current condition (66%); acute illness (33%); terminal disease (8%); functional impairment (8%); and dementia (7%). The percentage of those with a living will who thought their living wills would play a role in the scenarios was as follows: acute illness (84%); terminal disease (93%); functional impairment with intact cognition (66%); and dementia (91%). Factor analysis of the life value statements revealed five meaningful factors: quality of life; capacity/autonomy; family relations; physical comfort; and treatment philosophy. Multiple correlations were found between four of five life value factors and hypothetical resuscitation preferences or the presence of a living will. CONCLUSION: Subjects misinterpreted the applicability of living wills in nonterminal illness scenarios. A relationship between life values and resuscitation preferences was noted, which emphasizes the importance of eliciting and including life values when discussing advance directives.
