Age-related differences in care preferences, treatment decisions, and clinical outcomes of seriously ill hospitalized adults: lessons from SUPPORT

Patient views about treatment of stage 5 CKD: a qualitative analysis of semistructured interviews

BACKGROUND

How patients choose between alternative treatments for kidney failure is poorly understood. Recent studies of chronic kidney disease report that clinical outcomes, such as life expectancy, are rarely reflected in a patient's decision for type of treatment compared with nonclinical outcomes, such as time on dialysis therapy, convenience, or impact on the family.

METHODS

A qualitative analysis using thematic synthesis of patient views about renal replacement therapy (RRT) was undertaken. As part of a national study of patients and renal health care providers, we interviewed 95 Australian dialysis and transplant patients to explore how they perceive these alternative treatments.

RESULTS

52 patients were on satellite hemodialysis therapy, 8 patients were on incenter hemodialysis therapy, 8 patients were on continuous ambulatory peritoneal dialysis therapy, 5 patients were on automated peritoneal dialysis therapy, 4 patients were on home hemodialysis therapy, and 18 patients had a functioning transplant at the time of interview. Freedom, convenience, self-care, effectiveness, and simplicity were commonly cited positive characteristics, whereas confinement, risk, family burden, pain, and time commitment were negative characteristics associated with RRTs. Characteristics were not specific to dialysis modalities, and some (eg, self-care) were seen as both positive and negative. A limitation of the study was that only 17 of 77 (22%) dialysis patients interviewed were on a home-based therapy.

CONCLUSIONS

Patients preferred RRTs that enhanced their freedom and autonomy and were convenient, effective, and simple. Treatments that minimized confinement and risk also were viewed positively. Our analysis suggests that patients might choose between therapies based on their perception regarding which therapy most embodies particular characteristics that minimize impact on their lifestyle. Presentation of information regarding RRTs should focus on these characteristics and the potential impact of alternative treatments on the patients and how they wish to lead their lives.

Treating cancer patients who are near the end of life in the emergency department

Cancer-related visits to the emergency department (ED) can be expected to increase in the next decade as the population ages. Some of the these patients and their caregivers will come to the ED without prior end-of-life care planning, and others will require modification of prior plans based on disease progression. In this article, we discuss some of these end-of-life issues related to and including those of legal documents, transmission of patient wishes, limiting factors in implementing those wishes, and the new horizon of palliative care in the ED.

End-of-life issues in the acute and critically ill patient

The challenges of end-of-life care require emergency physicians to utilize a multifaceted and dynamic skill set. Such skills include medical therapies to relieve pain and other symptoms near the end-of-life. Physicians must also demonstrate aptitude in comfort care, communication, cultural competency, and ethical principles. It is imperative that emergency physicians demonstrate a fundamental understanding of end-of-life issues in order to employ the versatile, multidisciplinary approach required to provide the highest quality end-of-life care for patients and their families.

Prolonged acute mechanical ventilation, hospital resource utilization, and mortality in the United States

OBJECTIVE

Adjusted costs of mechanical ventilation (MV) are $1,500 per patient-day. We compared the prevalence, characteristics, and outcomes of MV < 96 hrs (MV < 96) and prolonged acute MV (PAMV) of > or = 96 hrs' duration in a representative sample of U.S. hospital discharges.

DESIGN

A multicenter cross-sectional study.

SETTING

Nationally representative sample of U.S. hospital discharges.

PATIENTS

Adult hospital discharges were identified from the 2003 Nationwide Inpatient Sample, Healthcare Cost and Utilization Project from the Agency for Healthcare Research and Quality (AHRQ). PAMV was based on the presence of ICD-9 code 96.72, and MV < 96 hrs based on ICD-9 codes 96.70 and 96.71.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of 31,340,578 discharges for adults (> or = 18 yrs), 2.4% had any MV, of which 469,168 (61%) had MV < 96, and 294,333 (39%) had PAMV. Patient demographics were similar for MV < 96 and PAMV. With the exception of acute myocardial infarction and chronic and end-stage renal disease without dialysis, the prevalence of coexisting conditions was higher in the PAMV group. Median length of stay (17 vs. 6 days) and hospital costs ($40,903 vs. $13,434) also were higher with PAMV vs. MV < 96. Although Agency for Healthcare Research and Quality disease severity and mortality probability were higher in the PAMV than MV < 96 group, actual mortality was similar between the two groups (34% vs. 35%).

CONCLUSIONS

There were nearly 300,000 PAMV discharges in the United States in 2003 at an annual aggregated hospital cost of > $16 billion, or nearly two thirds of the cost for all of the MV discharges. Despite a higher predicted mortality, patients requiring PAMV had the same likelihood of being discharged alive as those on shorter-term MV. These analyses will help inform health care decision-making and resource planning in the face of an aging population.

Uncomplicated acute renal failure and post-hospital care: a not so uncomplicated illness

BACKGROUND

Although uncomplicated acute renal failure (ARF) is associated with significant hospital resource utilization, its health care requirements following hospital discharge are not well understood. The goal of this study was to characterize the post-hospital care requirements incurred by patients with uncomplicated ARF and to determine its important influencing factors.

METHODS

We obtained hospital case mix data sets for a 2-year period (1999-2000) from the Massachusetts Division of Health Care Finance and Policy. Utilizing DRG and ICD-9-CM codes from 23 Massachusetts hospitals, we identified 2,128 adult patients whose primary reason for hospitalization was uncomplicated ARF. Post-hospital care was defined as the receipt of extended facility care or home health care following hospital discharge.

RESULTS

Nearly 50% of patients hospitalized with uncomplicated ARF required some type of post-hospital care, of whom 27% underwent extended facility care while 22% received home health care. The post-hospital care requirements for uncomplicated ARF were similar to those for serious medical conditions (e.g. heart failure) and exceeded those of many common illnesses (e.g., bronchitis). Advancing age, worsening severity of illness, female gender, and emergency room admission were independently associated with receipt of post-hospital care (p < 0.05). A trend existed between less frequent post-hospital care requirements and hospitalization at academic medical centers compared with non-academic hospitals.

CONCLUSIONS

Uncomplicated ARF is frequently associated with prolonged care following hospitalization. As the health care utilization for ARF becomes better characterized, these post-hospital care resources should not be overlooked.

Hospital Recovery is Facilitated by Prevention of Pressure Ulcers in Older Adults

Pressure ulcers are areas of tissue damage caused by unrelieved pressure that results in ischemia. About 70% of pressure ulcers occur in adults who are older than 65 years of age; the most common sites are the sacrum and heels. The rate at which new ulcers develop in acute care settings varies from 0.4% to 38%, with a mean incidence of about 7%. Recovery in patients who have pressure ulcers is delayed, as demonstrated by an increased length of hospitalization and increased health care costs. This article addresses recovery in older adults who are at risk for the development of a pressure ulcer.

The end of life: a qualitative study of the perceptions of people over the age of 80 on issues surrounding death and dying

This study explored how elderly people living in the community perceive issues around death, dying, and the end of life using a qualitative grounded theory approach. Forty individuals aged between 80 and 89 years who were living alone in the community were interviewed and were identified through purposive and random sampling. The results revealed that issues associated with end of life included fear of how they would die, fear of becoming a burden to others, wanting to prepare for and have a choice with regard to where and when they die, and issues relating to assisted dying. The study demonstrated that issues relating to the end of life are a major concern for older people, but are seldom addressed by professionals. Listening to and understanding the views and experiences of the older age group regarding end-of-life care is needed if adequate person-centered care is to be delivered to this ever-growing population group.

Acute Coronary Care in the Elderly, Part II

Background— Age is an important determinant of outcomes for patients with acute coronary syndromes. However, community practice reveals a disproportionately lower use of cardiovascular medications and invasive treatment even among elderly patients who would stand to benefit. Limited trial data are available to guide care of older adults, which results in uncertainty about benefits and risks, particularly with newer medications or invasive treatments and in the setting of advanced age and complex health status.

Methods and Results— Part II of this American Heart Association scientific statement summarizes evidence on presentation and treatment of ST-segment–elevation myocardial infarction in relation to age (<65, 65 to 74, 75 to 84, and ≥85 years). The purpose of this statement is to identify areas in which the evidence is sufficient to guide practice in the elderly and to highlight areas that warrant further study. Treatment-related benefits should rise in an elderly population, yet data to confirm these benefits are limited, and the heterogeneity of older populations increases treatment-associated risks. Elderly patients with ST-segment–elevation myocardial infarction more often have relative and absolute contraindications to reperfusion, so eligibility for reperfusion declines with age, and yet elderly patients are less likely to receive reperfusion even if eligible. Data support a benefit from reperfusion in elderly subgroups up to age 85 years. The selection of reperfusion strategy is determined more by availability, time from presentation, shock, and comorbidity than by age. Additional data are needed on selection and dosing of adjunctive therapies and on complications in the elderly. A “one-size-fits-all” approach to care in the oldest old is not feasible, and ethical issues will remain even in the presence of adequate evidence. Nevertheless, if the contributors to treatment benefits and risks are understood, guideline-recommended care may be applied in a patient-centered manner in the oldest subset of patients.

Conclusions— Few trials have adequately described treatment effects in older patients with ST-segment–elevation myocardial infarction. In the future, absolute and relative risks for efficacy and safety in age subgroups should be reported, and trials should make efforts to enroll the elderly in proportion to their prevalence among the treated population. Outcomes of particular relevance to the older adult, such as quality of life, physical function, and independence, should also be evaluated, and geriatric conditions unique to this age group, such as frailty and cognitive impairment, should be considered for their influence on care and outcomes. With these efforts, treatment risks can be minimized, and benefits can be placed within the health context of the elderly patient.

Differences in veterans' and nonveterans' end-of-life preferences: a pilot study

BACKGROUND

Investigators conducting focus groups on end-of-life preferences noted that veterans voiced opinions that strongly differed from those of nonveterans.

OBJECTIVE

The objective of this study was to further explore differences between veterans' and nonveterans' end-of-life preferences.

METHODS

Ten focus groups and a pilot survey were conducted.

SETTING AND SAMPLE

The focus groups consisted of Arab Muslims, Arab Christians, Hispanics, blacks, and whites stratified by gender (n = 73). Fifteen male veterans were included across all five racial groups.

MEASURES

A moderator discussion guide was used to lead the focus groups and a pilot survey asked about demographic information and end-of-life preferences.

RESULTS

Veterans were more likely to be married (p < 0.05) and less connected to their cultural group (p < 0.05) than nonveterans. The focus group results indicated that veterans in this study were more likely to oppose the use of heroic measures compared to nonveterans. More so than nonveterans, veterans felt that their doctors should be frank and open (p < 0.05) were strongly in favor of do-not-resuscitate (DNR) orders (p < 0.10), yet were less likely to have a proxy (p < 0.10) or durable power of attorney p < 0.01). Comparing end-of-life preferences, veterans felt less strongly than nonveterans about remembering personal accomplishments (p < 0.05), being listened to (p < 0.05), being with friends (p < 0.01), or being comfortable with their nurse (p < 0.05), but did want to be around their pets at the end of life p < 0.10).

IMPLICATIONS

The Department of Veterans Affairs is in a unique position to improve endof- life care for veterans. Providing end-of-life care that is congruent with the veteran's wishes can improve satisfaction and increase cost effectiveness by eliminating unacceptable services.

Death, dying, and last wishes

Issues regarding patient care near the end of life can be challenging and rewarding for emergency physicians. Knowledge of the patient's wishes is essential, and may be accomplished by advance directives or communication with patients and surrogates. Resuscitative efforts are appropriate for many patients, but inappropriate for others. The goals of medicine remain the following: providing optimal health care, provision of the best possible symptom control, communication, empathy, and caring. As death approaches, provision of the best possible medical care, in accordance with the patient's wishes, can be rewarding for patients, families, and health care providers.

Hospitalizations during the last months of life of nursing home residents: a retrospective cohort study from Germany

Background

To describe hospitalisations of nursing home (NH) residents in Germany during their last months of life.

Methods

Retrospective cohort study on 792 NH residents in the Rhine-Neckar region in South-West Germany, newly institutionalized in the year 2000, who died until the study end (December 2001). Baseline variables were derived from a standardized medical examination routinely conducted by the medical service of the health care insurance plans in Germany. Information on hospitalisations and deaths was extracted form records of the pertinent health insurance plans.

Results

NH residents who died after NH stay of more than 1 year spent 5.8% of their last year of life in hospitals. Relative time spent in hospitals increased from 5.2% twelve months before death (N = 139 persons) to 24.1% in their last week of life (N = 769 persons). No major differences could be observed concerning age, gender or duration of stay in NH. Overall, 229 persons (28.9%) died in hospital. Among these, the last hospital stay lasted less than 3 days for 76 persons (31.9%). Another 25 persons (3.2%) died within three days after hospital discharge.

Conclusion

Our study indicates that proximity of death is the most important driver of health care utilization among NH residents. The relation of age or gender to health care expenditures seem to be weak once time to death is controlled for. Duration of NH stay does not markedly change rates of hospitalisation during the last months of life.

Resuscitation of the Elderly

The changing demographics of America's population over the past couple of decades have propelled geriatric medicine into the fore-front. Due to this, emergency medicine physicians will face numerous challenges managing an increasing number of critically ill elderly patients. This article will focus on success of resuscitation in this population, important pathophysiologic changes that occur with aging, as well as ethical considerations in end-of-life care.

Patient desires: A model for assessment of patient preferences for care of severe or terminal illness

Objective:Patient-centered care is better achieved through a comprehensive understanding of patients' preferences for how they want to live their life and how they want to influence their own death. Though much has been written on identifying goals of care, it is often difficult for clinicians to articulate patient goals to guide care planning. We explored the literature on patient's preferences for their care in chronic or life-limiting illness to develop a model for assessment of patient perspectives. We then illustrated our model with composite patients from our clinics and we provide questions to guide patient discussion.

Methods:We searched MEDLINE from 1986 to 2004 for primary research articles that relate primarily to a patient's preferences for his or her care. We reviewed over 3500 titles, abstracts, and research papers. Hundreds of articles described patients' quality of life, health status, or satisfaction. We excluded consensus guidelines, non-English papers, reviews, and articles focused on medical professional perspectives. Forty-eight studies focused primarily on patient preferences. Using an iterative process, we identified unique issues and broader themes in patients' desires for their care.

Results:Studies focused on patients with cancer, those in hospice or those with terminal disease. Three domains emerged: patient feelings about disease, feelings about suffering, and feelings about the circumstances of death. Attention was given to the differences between patients in terms of the strength and persistence of feelings in each domain.

Significance of results:Based on existing data, there are three fundamental domains of patient perspective that influence preferences for care. These domains can be assessed by the care team to guide the development of a plan of care and to identify areas of conflict. Our review identifies gaps in the end-of-life literature and areas for future work in patient preferences.

Medical decision-making for seriously ill non-elderly and elderly patients

OBJECTIVES

Age of patients by itself is no longer a contra-indication for most medical interventions. The increase of possible interventions for elderly patients has contributed to a sharp age-specific increase of health care costs. Our study aimed to increase the insight in medical decision-making about life-prolonging interventions for patients from non-elderly and elderly age groups.

DESIGN

Case-control study.

SETTING

Clinical practices in three settings: oncology, nursing home and cardiology.

SUBJECTS

Eighty-one physicians, representing a response of 60%.

METHODS

Face-to-face interviews using a structured questionnaire addressing decision-making about the application of taxoid treatment for breast cancer patients, the application of bypass surgery for patients with angina pectoris under or over 70 years of age, and referral to specialist treatment because of a suspected malignancy of nursing home patients under or over 75 years of age.

RESULTS

The chance of having been treated was in all settings lower for patients with a relatively poor quality of life and for patients who had no (known) preference to be treated. No differences were found for chance of having been treated between non-elderly and elderly patients with similar patient characteristics. The only exception to this is the patient preference concerning treatment: elderly patients were more likely to have been treated against their will than non-elderly patients were.

CONCLUSIONS

A relatively high frequency of non-treatment decisions for elderly patients may be predominantly explained by the fact that patient characteristics that determine non-treatment decision-making are more prevalent in elderly age groups, and not by the effect of age per se.

Becky's legacy: personal and professional reflections on loss and hope

The author, a psychologist who has been specializing in end-of-life issues for over a decade, uses the death of his fiancée (Becky), following the withdrawal of a ventilator and the refusal to place her back on the machine, to discuss research and analysis of end-of-life care in the United States. After briefly discussing his own background, Becky's history, and their relationship, he details Becky's last weeks of life and the first weeks of his grieving process. This story provides a background for discussing end-of-life issues including what constitutes a "good death," concerns about aggressive treatment and the cost of care near the end of life, prognosis, advance directives, and demographic issues. There is also a major section on psychosocial issues that arise when a person is dying. The author concludes with a set of "lessons learned" as a result of his relationship with Becky and going through the dying process with her and her family.

Efficacy of proton magnetic resonance spectroscopy in neurological diagnosis and neurotherapeutic decision making

Anatomic and functional neuroimaging with magnetic resonance imaging (MRI) includes the technology more widely known as magnetic resonance spectroscopy (MRS). Now a routine automated "add-on" to all clinical magnetic resonance scanners, MRS, which assays regional neurochemical health and disease, is therefore the most accessible diagnostic tool for clinical management of neurometabolic disorders. Furthermore, the noninvasive nature of this technique makes it an ideal tool for therapeutic monitoring of disease and neurotherapeutic decision making. Among the more than 100 brain disorders that fall within this broad category, MRS contributes decisively to clinical decision making in a smaller but growing number. In this review, we will cover how MRS provides therapeutic impact in brain tumors, metabolic disorders such as adrenoleukodystrophy and Canavan's disease, Alzheimer's disease, hypoxia, secondary to trauma or ischemia, human immunodeficiency virus dementia and lesions, as well as systemic disease such as hepatic and renal failure. Together, these eight indications for MRS apply to a majority of all cases seen. This review, which examines the role of MRS in enhancing routine neurological practice and treatment concludes: 1) there is added value from MRS where MRI is positive; 2) there is unique decision-making information in MRS when MRI is negative; and 3) MRS usefully informs decision making in neurotherapeutics. Additional efficacy studies could extend the range of this capability.

To know or not to know: the case of communication by and with older adult Russians diagnosed with cancer

This paper describes the ways in which group identifications and stereotypes can inform our understanding of cancer treatment and survivorship, as well as the more general social processes surrounding the communicative experiences of older adult Russians diagnosed with cancer, by providing a theoretical essay (with some modest illustrative data) to shed light on salient cross-cultural health and identity issues. Utilizing an approach grounded in social identity theory, it describes the ways in which understanding primary identities associated with large social collectives such as cultural groups, secondary identities associated with health behaviors and tertiary identities associated with a cancer diagnosis can help explain certain cancer-related social processes. Subtle cultural differences in approaches to health care, particularly with older adult populations, are likely influenced by assumptions embedded in their economic, social, and political systems.

Association of Depression and Life-Sustaining Treatment Preferences in Patients With COPD

STUDY OBJECTIVE

Depressive symptoms and reduced health-related quality of life are common in patients with severe COPD. Therefore, understanding the association between preferences for life-sustaining treatment and depression or quality of life is important in providing care. No prior studies have examined the effects of depression and quality of life on treatment preferences in this population.

DESIGN AND PATIENTS

Cross-sectional study of 101 patients with oxygen-prescribed COPD.

METHODS

Patients completed the St. George's Respiratory Questionnaire, Center for Epidemiologic Studies-Depression survey, and questions regarding their preferences for mechanical ventilation and cardiopulmonary resuscitation if needed to sustain life.

RESULTS

Median age was 67.4 years, and median FEV1 was 26.3% predicted. Depression was significantly associated with preferences for resuscitation (50% of depressed patients and 23% of patients without depression refused resuscitation; p = 0.007), but was not associated with preferences for mechanical ventilation. Health-related quality of life was not associated with preferences for either resuscitation or mechanical ventilation.

CONCLUSIONS

Clinicians caring for patients with oxygen-prescribed COPD should understand that health-related quality of life does not predict treatment preferences and should not influence clinicians' views of patients' treatment preferences. However, depression does appear to influence patients' treatment decisions for cardiopulmonary resuscitation, and improvement in depressive symptoms should trigger a reassessment of these preferences.

Hospitalizations for tuberculosis in the United States in 2000: predictors of in-hospital mortality

STUDY OBJECTIVES

Despite curative therapy, mortality remains high for hospitalized patients with tuberculosis (TB) in the United States. The purpose of this study was to describe the characteristics of hospitalized patients with TB and to identify patient characteristics associated with in-hospital mortality.

DESIGN, SETTING, AND PATIENTS

Using the 2000 Nationwide Inpatient Sample, representing 20% of US hospital admissions, we identified 2,279 hospital admissions with a primary diagnosis of TB (International Classification of Diseases, ninth revision, codes, 010.xx to 018.xx).

MEASUREMENTS AND RESULTS

Mortality was the main outcome measure. Logistic regression analyses were performed including age, gender, race, insurance status, income, Deyo-adapted Charlson comorbidity index (DCI), HIV status, hospital admission source, and hospital characteristics as explanatory variables. A disproportionate number of patients hospitalized with TB were men (64%), nonwhite (72%), lived in areas with median incomes of < $35,000 (50%), and had publicly funded health insurance (49%) or no health insurance (17%). The mortality rate for patients hospitalized for TB was greater than that for non-TB hospital admissions (4.9% vs 2.4%, respectively; p < 0.001). Patients with TB who died during hospitalization were older (mean age, 65.1 vs 49.4 years, respectively; p < 0.001), had greater comorbid illness (DCI, 1.1 vs 0.55, respectively; p < 0.001), required longer hospitalizations (19.9 vs 13.9 days, respectively; p < 0.001), and accumulated substantially higher charges ($79,585 vs $31,610, respectively; p < 0.001) than did patients with TB who were alive at hospital discharge. In a multivariable analysis, older age, comorbid illnesses, and emergency department admissions were independently associated with mortality. The total charges for TB hospitalizations in the United States in 2000 exceeded $385 million.

CONCLUSIONS

Despite public health efforts, patients who are hospitalized with TB are frequently admitted through emergency care settings, have a high risk of in-hospital mortality, and incur substantial hospital charges. To improve TB health outcomes, more vigorous clinical management and prevention strategies should especially target older patients and those with comorbid medical conditions.

Preferences in end-of-life care of older persons: after-death interviews with proxy respondents

This population-based study employing after-death interviews with proxies describes older persons' preferences regarding medical care at the end of life. Interviews were held with 270 proxy respondents of 342 deceased persons (age range 59-91) in the Netherlands, The deceased were respondents to the Longitudinal Aging Study Amsterdam. The prevalence of advance directives (ADs), preferences for medical decisions at the end of life (i.e. withholding treatment, physician-assisted suicide euthanasia) and preferences about the focus of treatment in the last week of life (i.e. comfort care versus extending life) were examined. Written ADs were present in 14% of the sample. A quarter had designated a surrogate decision-maker. Co-morbidity and perceived self-efficacy (PSE) were positively associated with ADs. About half the sample had expressed a preference in favour or against one or more medical decisions at the end of life. Predictors positively associated with expressing a preference were co-morbidity, dying from cancer, and PSE. Being religious was negatively associated with expressing a preference. The knowledge of the proxy regarding the older person's preference for the focus of treatment was dependent on the patient's symptom burden as perceived by the proxy. The majority of older persons had died without either an AD, or having expressed preferences for end-of-life care. Stimulating the formulation of ADs may help professionals who work with older people to understand these preferences better, especially in the case of non-cancer patients and those with low PSE.

Prognosis of patients aged 80 years and over admitted in medical intensive care unit

OBJECTIVE

To determine the prognostic indicators of long-term survival after admission to a medical intensive care unit (MICU) for patients aged 80 years and over. DESIGN. Prospective cohort study.

SETTING

A 14-bed MICU in a 970-bed, acute care, tertiary, university hospital in Paris, France.

PATIENTS

A total of 233 patients aged 80 years and over discharged from a MICU during a 2-year period.

MEASUREMENTS AND MAIN RESULTS

Severity at admission was estimated using the Simplified Acute Physiology Score. The underlying condition was classified using the MacCabe classification. The functional status was assessed using the Knaus classification. The outcome after MICU discharge was determined after a median 2-year follow-up. The functional outcome was assessed by telephone interviews, employing the Instrumental Activities of Daily Living (IADL). The in-MICU mortality was 19.5% including death occurring during the 2 days following discharge. The long-term survival rates for patients admitted to the MICU were 59% at 2 months, 33% at 2 years, and 29% at 3 years. The multivariate analysis identified two prognostic factors of death after discharge: presence of an underlying fatal disease (HR 1.7; 95% CI 1.1-2.6) and severe functional limitation (HR 1.7; 95% CI 1.2-2.6). The IADL was excellent or good for 56% of the surviving patients.

CONCLUSION

Long-term survival after MICU is mainly related to the underlying condition, whereas known factors for in-MICU survival do not influence long-term prognosis.

Controversial issues in critical care for the elderly: a perspective from Canada

Age alone does not at all preclude the possibility of warranted, effective, and successful intensive care. From a medical perspective, the key issue is the reversibility or otherwise of an acute illness and where this illness sits in the trajectory of that individual's life and possible death. It makes no more sense to admit a 19-year-old let alone a 91-year-old to an intensive care unit if intensive care cannot provide what is needed. Of paramount importance in our consideration of critical care for the elderly is a determination and an understanding of the many needs--medical, emotional, social, spiritual, psychologic--that elderly people have. By exploring them with compassion and sensitivity, we can establish whether the goals of care include critical care and the associated technology, or whether alternative and more conservative approaches more closely reflect the values and preferences of an increasingly elderly population.

Hospitalization of Hospice Patients with Cancer

OBJECTIVES

To identify factors associated with hospitalization of elderly hospice patients with cancer and to describe their hospital experiences.

DESIGN

Retrospective analysis of the last year of life.

SETTING

Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database.

PARTICIPANTS

Medicare beneficiaries dying of lung or colorectal cancer between 1988 and 1998 who enrolled in hospice.

MEASUREMENTS

Hospitalization after hospice entry. For hospitalized patients, we describe admission diagnoses, aggressiveness of care, and in-hospital death.

RESULTS

Of the 23608 patients, 1423 (6.0%) were hospitalized after hospice enrollment. Hospitalization declined over time by 7.0% per year of hospice enrollment. Factors associated with higher hospitalization rates were younger age, male gender, black race/ethnicity, local cancer stage at diagnosis, and hospice enrollment within 4 months of cancer diagnosis. The most common reasons for hospital admission were lung cancer, metastatic disease, bone fracture, pneumonia, and volume depletion. Of the 1423 patients hospitalized, 34.6% received aggressive care and 35.8% died in the hospital.

CONCLUSION

The rates of hospitalization for elderly hospice patients with lung or colorectal cancer appear to be declining. However, patients who are hospitalized undergo aggressive care and often die in the hospital rather than at home. This aggressive care may be consistent with changes in patients' care preferences, but could also reflect the current culture of acute care hospitals, which focuses on curative treatment and is ill-equipped to provide palliative care.

Effect of age on the development of ARDS in trauma patients

STUDY OBJECTIVES

The purpose of this study was to determine the independent effect of age on the risk of developing ARDS in patients with trauma.

DESIGN

Prospective cohort study.

SETTING

Level I trauma center.

MEASUREMENTS AND RESULTS

A total of 4,020 consecutive trauma patients who were > 12 years of age were identified through the Harborview Medical Center Trauma Registry over a 3-year period. During this time, 484 of the trauma patients (12%) developed ARDS, as identified by the Harborview Medical Center ARDS Registry. Patients who developed ARDS were, on average, older (mean [+/- SD] age, 44.0 +/- 18.8 vs 40.2 +/- 20.0 years, respectively; p < 0.0001) and had higher injury severity scores (23.7 +/- 11.3 vs 18.0 +/- 10.3, respectively; p < 0.0001) than trauma patients who did not develop ARDS. The maximum unadjusted odds ratio for developing ARDS was 2.93 (95% confidence interval, 1.91 to 4.50) for the group 60 to 69 years of age compared to the group 13 to 19 years of age. Patients aged > or = 80 years had an equal risk of developing ARDS compared to those age 13 to 19 years.

CONCLUSIONS

Age demonstrated a complex relationship with risk for ARDS development. Older patients showed increasingly higher risks for ARDS development up to 60 to 69 years of age, when the risk for ARDS declined. We concluded that older patients are at significantly greater risk of developing ARDS when compared to younger patients, while the oldest patients may be at less risk.

What does it mean to be critically ill and elderly?

The number of critically ill elderly continues to rise, causing health care workers to be faced with decisions regarding aggressiveness of care, rationing of resources, and optimizing outcome. Although survival rates in the critically ill elderly may be lower than those in the younger critically ill, health care workers must focus on customizing treatment to optimize physiologic recovery, quality of life, and functional status. We advocate better research designs incorporating long-term outcomes and genetic predisposition as a means of improving care in the elderly critically ill.

Public education regarding resuscitation: effects of a multimedia intervention

STUDY OBJECTIVE

Previous studies have demonstrated inaccuracies in knowledge and perceptions regarding cardiopulmonary resuscitation (CPR) among the general public. This study was undertaken to determine the effect of a multimedia educational intervention on knowledge base and resuscitation preferences among the lay public.

METHODS

In this prospective interventional study with preintervention and postintervention measurements, a validated multisite survey was administered to 310 volunteer lay participants in community-based settings during 2001 and 2002. The survey was piloted and validated (percentage of agreement index 98.6%; 95% confidence interval [CI] 0.9810 to 0.9900). An original 8-minute multimedia educational video was written and produced by physicians to provide educational information about cardiac resuscitation to the lay public.

RESULTS

Among 310 participants, the mean age was 40 years (range 17 to 92 years), 67% were female, and 57% reported household incomes of more than 30,000 US dollars. Participants' median estimates of predicted postcardiac arrest survival rate before and after the educational intervention were 50% and 16%, respectively (median change 30%; 95% CI 25% to 35%). Median estimated durations of resuscitative efforts in the emergency department before and after the educational intervention were 30 minutes and 19 minutes, respectively (median change 10 minutes; 95% CI 5 to 15 minutes). For a series of hypothetical scenarios, significantly more participants indicated that they would refuse resuscitative efforts in scenarios involving terminally ill patients after the educational intervention.

CONCLUSION

Inaccurate perceptions regarding cardiac resuscitation and postarrest survival exist among the lay public. A novel educational intervention demonstrated effective improvements in knowledge base regarding resuscitation, resulting in significant effects on resuscitation preferences among the lay public. Improved public education regarding resuscitation is needed to improve knowledge regarding CPR among the lay public.

Family involvement in end-of-life hospital care

OBJECTIVES

To examine whether the end-of-life treatment provided to hospitalized patients differed for those who had a family member present at death and those who did not.

DESIGN

A retrospective cohort analysis.

SETTING

An urban community hospital.

PARTICIPANTS

All 370 inpatients who died during a 1-year period.

MEASUREMENTS

Medical records were examined for whether life-support treatments were provided or withdrawn, occurrence and timing of do-not-resuscitate (DNR) orders, and use of comfort measures such as narcotics and sedation.

RESULTS

DNR orders were written for 85% of patients. For patients who had a DNR order written, the average time from the DNR order to death was 4.8 days. Only 26% of patients had one or more treatments withdrawn. Sixty-seven percent of patients received narcotics before death, and 22% received sedatives. Patients aged 75 and older and African Americans were less likely to have a family member present at death. After adjusting for age and ethnicity, patients who had a family member present at death were more likely to have DNR orders written, to have treatments withdrawn, and to receive narcotics before death. Patients with a family member present at death also had a shorter time to death after DNR orders were written.

CONCLUSION

The presence of a family member at death appears to be an indirect measure of family involvement during patients' hospitalization. Family involvement before death may reduce the use of technology and increase the use of comfort care as patients die.

Loss of independence in activities of daily living in older adults hospitalized with medical illnesses: increased vulnerability with age

OBJECTIVES

To describe the changes in activities of daily living (ADL) function occurring before and after hospital admission in older people hospitalized with medical illness and to assess the effect of age on loss of ADL function.

DESIGN

Prospective observational study.

SETTING

The general medical service of two hospitals.

PARTICIPANTS

Two thousand two hundred ninety-three patients aged 70 and older (mean age 80, 64% women, 24% nonwhite).

MEASUREMENTS

At the time of hospital admission, patients or their surrogates were interviewed about their independence in five ADLs (bathing, dressing, eating, transferring, and toileting) 2 weeks before admission (baseline) and at admission. Subjects were interviewed about ADL function at discharge. Outcome measures included functional decline between baseline and discharge and functional changes between baseline and admission and between admission and discharge.

RESULTS

Thirty-five percent of patients declined in ADL function between baseline and discharge. This included the 23% of patients who declined between baseline and admission and failed to recover to baseline function between admission and discharge and the 12% of patients who did not decline between baseline and admission but declined between hospital admission and discharge. Twenty percent of patients declined between baseline and admission but recovered to baseline function between admission and discharge. The frequency of ADL decline between baseline and discharge varied markedly with age (23%, 28%, 38%, 50%, and 63% in patients aged 70-74, 75-79, 80-84, 85-89, and > or =90, respectively, P <.001). After adjustment for potential confounders, age was not associated with ADL decline before hospitalization (odds ratio (OR) for patients aged > or =90 compared with patients aged 70-74 = 1.26, 95% confidence interval (CI) = 0.88-1.82). In contrast, age was associated with the failure to recover ADL function during hospitalization in patients who declined before admission (OR for patients aged > or =90 compared with patients aged 70-74 = 2.09, 95% CI = 1.20-3.65) and with new losses of ADL function during hospitalization in patients who did not decline before admission (OR for patients aged > or =90 compared with patients aged 70-74 = 3.43, 95% CI = 1.92-6.12).

CONCLUSION

Many hospitalized older people are discharged with ADL function that is worse than their baseline function. The oldest patients are at particularly high risk of poor functional outcomes because they are less likely to recover ADL function lost before admission and more likely to develop new functional deficits during hospitalization

Social identity and health: an intergroup communication approach to cancer

This article describes the ways in which group identifications and stereotypes can inform our understanding of cancer prevention and treatment as well as more general social processes surrounding the experience of cancer. From a perspective grounded in social identity theory, we describe the ways in which understanding primary identities (i.e., those associated with large social collectives such as cultural groups), secondary identities (i.e., those associated with health behaviors), and tertiary identities (i.e., those associated with cancer) can help explain certain cancer-related social processes. We forward a series of propositions to stimulate further research on this topic.

Research design in end-of-life research: state of science

PURPOSE

The volume of research on end-of-life care, death, and dying has exploded during the past decade. This article reviews the conceptual and methodological adequacy of end-of-life research to date, focusing on limitations of research to date and ways of improving future research.

DESIGN AND METHODS

A systematic search was conducted to identify the base of end-of-life research. Approximately 400 empirical articles were identified and are the basis of this review.

RESULTS

Although much has been learned from research to date, limitations in the knowledge base are substantial. The most fundamental problems identified are conceptual and include failure to define dying; neglect of the distinctions among quality of life, quality of death, and quality of end-of-life care. Methodologically, the single greatest problem is the lack of longitudinal studies that cover more than the time period immediately before death.

IMPLICATIONS

Gaps in the research base include insufficient attention to psychological and spiritual issues, the prevalence of psychiatric disorder and the effectiveness of the treatment of such disorders among dying persons, provider and health system variables, social and cultural diversity, and the effects of comorbidity on trajectories of dying.

Outcomes of and Resource Consumption by High-Cost Patients in the Intensive Care Unit

• Background Care of patients in an intensive care unit is among the most costly in hospitals. Little is known about high-cost patients within the intensive care unit or their outcomes of care.

• Objectives To examine outcomes of and resource consumption by high-cost adult patients who received care in an intensive care unit at an academic medical center.

• Methods Data on patients admitted during the period January 1, 1995, through June 30, 1999, were analyzed retrospectively. An intensive care unit database, the hospital discharge data set, and a cost-accounting data set were used to determine the total intensive care unit cost for the hospitalization. Patients were then stratified into cost deciles. Hospital and intensive care unit outcomes for patients in the top decile were compared with those of patients in the other deciles.

• Results Cost data were available on 10606 of the 11244 patients who received care in an intensive care unit. Patients in the top decile accounted for 48.7% of all intensive care unit costs, and 67.6% of this group survived to discharge despite prolonged care. Patients transferred from an outside hospital were more likely to be in the top decile, have a longer stay in the intensive care unit, or die than were the other patients.

• Conclusions A small group of patients accounts for a disproportionately higher amount of intensive care unit resources but has a relatively high survival rate. This cohort should be treated as an intact group that is not amenable to traditional cost-cutting measures.

The use of life-sustaining treatments in hospitalized persons aged 80 and older

OBJECTIVES

To characterize the use of life-sustaining treatments in hospitalized patients aged 80 and older.

DESIGN

A prospective cohort study.

SETTING

Four teaching hospitals in the United States that participated in the Hospitalized Elderly Longitudinal Project (HELP).

PARTICIPANTS

Hospitalized patients aged 80 and older.

MEASUREMENTS

We report the rates of admissions to intensive and coronary care units and the rates of use of cardiopulmonary resuscitation (CPR), ventilators, right heart catheterization, artificial nutrition and hydration, surgical interventions, hemodialysis, and blood transfusions.

RESULTS

Of the 1,266 patients enrolled in HELP, 72 died during the enrollment hospitalization. The median age of those who died was 86 (range 83-89). Of the patients who died, the median number of activities of daily living impairments was two (range 1-4) before hospitalization, and 70% reported their baseline quality of life as fair or poor. Most patients who died had stated that they did not want aggressive care; 70% wanted their care focused on comfort rather than prolonging life, and 80% had a do-not-resuscitate order. However, the majority (63%) of the patients received one or more life-sustaining treatments before they died. Fifty-four percent were admitted to intensive or coronary care units, 43% were on a ventilator, 18% received CPR, 18% received tube feeding, 17% underwent surgery, 15% had right heart catheterization, 14% received blood transfusions, and 6% had hemodialysis. Intensive care did not affect survival time.

CONCLUSION

The use of life-sustaining treatments was prevalent in very old patients who died in the course of hospitalization, despite the fact that the majority had a preference for comfort care. This lack of congruence warrants further investigation and efforts to provide care that is more consistent with patients' preferences.

Assessing differences in care needs and service utilization in geriatric palliative care patients

Little is known of the palliative care needs and experiences of older adults. This study explored whether these needs differed from those of younger patients. We performed a retrospective data analysis of 1184 palliative care consultations in a major teaching hospital. There were statistically significant differences across age groups in patient demographic and clinical characteristics, advance care planning, and service utilization. Patients over age 80 had a reduced prevalence of cancer, a higher prevalence of dementia and incapacity, more frequent decisions to withhold or withdraw life-sustaining treatments, and fewer interventions for symptom management. The palliative care needs of older adults appear to be substantially different from those of younger patients. Dementia and incapacity profoundly influence decision-making, requiring more time and communication with patients and families.

Resuscitation research: future directions and ethical issues

Cardiopulmonary resuscitation research is a vital area of research that has made significant contributions to medical care over the last several decades. Abundant information currently exists in the medical literature, as a result of research in the areas of cardiac arrest and outcomes, physiology of cardiac arrest, pharmacologic treatments, mechanical interventions, and societal and ethical issues. Despite numerous clinical trials demonstrating physiologic benefit of various interventions, few interventions have had as much impact on outcomes of cardiac arrest as have improvements in out-of-hospital response times and rapid availability of medical treatment. Although abundant information exists regarding physiologic aspects of resuscitation, relatively little information exists about ethical, psychological, and social aspects of resuscitation. In addition to attempts to improve outcomes of cardiac arrest, researchers should also strive to improve the experiences of patients and families involved. These realities provide future strategies and directions for the best use of resuscitation research resources; although physiologic and pharmacologic research will always have significant roles in the improvement of medical care, the rapid delivery of out-of-hospital care and ethical issues will be indispensable areas of research focus in the future.

Principles of perioperative pain management in older adults

The consequences of poor planning for pain management during surgery of geriatric patients not only affect the immediate well-being of the patient but also have terrible socioeconomic implications. Delays in rehabilitation, increases in hospital lengths of stay, and increased comorbidity can be expected if interventions for pain management are either inadequate or excessive without appropriate monitoring. During surgery, seniors are likely to suffer from acute and chronic pain that must be addressed aggressively in the postoperative period to ensure a rapid functional recovery. New pain scales have been developed with seniors in mind, and greater testing of older scales in elderly populations have helped to identify measures of pain more suited to frail seniors. This article is designed to help clinicians to strategically implement optimal pain management principles and techniques and, thus, help to fulfill the obligation to relieve pain and suffering in patients in the perioperative period, which will ensure the greatest chance of recovery to optimal independence for patients.

Communication and decision-making in seriously ill patients: findings of the SUPPORT project. The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments

OBJECTIVES

The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) represents one of the largest and most comprehensive efforts to describe patient preferences in seriously ill patients, and to evaluate how effectively patient preferences are communicated. Our objective was to review findings from SUPPORT describing the communication of seriously ill patients' preferences for end-of-life care.

METHODS

We identified published reports from SUPPORT describing patient preferences and the communication of those preferences. We abstracted findings that addressed each of the following questions: What patient characteristics predict patient preferences for end of life care? How well do physicians, nurses, and surrogates understand their patients' preferences, and what variables are correlated with this understanding? Does increasing the documentation of existing advance directives result in care more consistent with patients' preferences?

RESULTS

Patients who are older, have cancer, are women, believe their prognoses are poor, and are more dependent in ADL function are less likely to want CPR. However, there is considerable variability and geographic variation in these preferences. Physician, nurse, and surrogate understanding of their patient's preferences is only moderately better than chance. Most patients do not discuss their preferences with their physicians, and only about half of patients who do not wish to receive CPR receive DNR orders. Factors other than the patients' preferences and prognoses, including the patient's age, the physician's specialty, and the geographic site of care were strong determinants of whether DNR orders were written. In SUPPORT patients, there was no evidence that increasing the rates of documentation of advance directives results in care that is more consistent with patients' preferences.

CONCLUSIONS

SUPPORT documents that physicians and surrogates are often unaware of seriously ill patients' preferences. The care provided to patients is often not consistent with their preferences and is often associated with factors other than preferences or prognoses. Improving these deficiencies in end-of-life care may require systematic change rather than simple interventions.
