Quality of life in adolescents with mild asthma.

The majority of individuals with asthma have mild disease, often in conjunction with allergic rhinitis and exercise-induced bronchoconstriction (EIB). Although health-related quality-of-life (HRQoL) is reduced in moderate to severe asthma and allergic rhinitis, little is known about the effect of mild asthma, mild allergic rhinitis, and EIB on HRQoL outcomes. The objective of this study was to determine the effect of mild asthma, allergic rhinitis, and EIB on HRQoL. A cross-sectional study was conducted of 160 adolescent athletes participating in a screening program to detect EIB. Generic HRQoL was assessed with the teen version of the pediatric quality-of-life inventory (PedsQL). Prior diagnoses of asthma, allergic rhinitis, and EIB, and current symptoms of dyspnea during exercise and asthma, were recorded. Lung function and the presence of EIB were determined by spirometry before and after an exercise challenge test. Adolescent athletes with a prior physician diagnosis of asthma had a lower HRQoL scale summary score (P<0.01) and lower physical functioning, emotional functioning, and school functioning domain scores (P values, 0.01-0.02) in comparison to adolescent athletes with no prior diagnosis of these disorders. Athletes with a prior diagnosis of asthma reported dyspnea during exercise more frequently than did those without asthma (P<0.001). Adolescent athletes with dyspnea during exercise had a lower scale summary score, and lower physical functioning, general well-being, and emotional functioning domain scores (P values, 0.02-0.03). These data show that mild asthma and dyspnea without asthma significantly affect HRQoL. Symptoms of dyspnea during exercise are common in asthma and are associated with lower HRQoL. The clinical significance of these differences in HRQoL is unclear.

Improving care for patients dying in the intensive care unit.

It is impossible for ICU clinicians to avoid caring for dying patients and their families. For many, this is an extremely rewarding aspect of their clinical practice. There is ample evidence that there is room to improve the care of patients who are near death in the ICU. Despite the considerable holes in our knowledge about optimal care of dying critically ill patients, there is considerable agreement on the general principles of caring for these patients and about how to measure the outcomes of palliative care in the ICU. Practical approaches to improving the quality of end-of-life care exist and should be implemented.

Physicians' interactions with health care teams and systems in the care of dying patients: perspectives of dying patients, family members, and health care professionals.

This study investigated the specific physician skills required to interact with health care systems in order to provide high quality care at the end of life. We used focus groups of patients with terminal diseases, family members, nurses and social workers from hospice or acute care settings, and physicians. We performed content analysis based on grounded theory. Groups were interviewed. Two domains were found related to physician interactions with health care systems: 1) access and continuity, and 2) team communication and coordination. Components of these domains most frequently mentioned included taking as much time as needed with the patient, accessibility, and respect shown in working with health team members. This study highlights the need for both physicians and health care systems to improve accessibility for patients and families and increase coordination of efforts between health care team members when working with dying patients and their families.

Dying patients' need for emotional support and personalized care from physicians: perspectives of patients with terminal illness, families, and health care providers.

This study addressed the emotional and personal needs of dying patients and the ways physicians help or hinder these needs. Twenty focus groups were held with 137 individuals, including patients with chronic and terminal illnesses, family members, health care workers, and physicians. Content analyses were performed based on grounded theory. Emotional support and personalization were 2 of the 12 domains identified as important in end-of-life care. Components of emotional support were compassion, responsiveness to emotional needs, maintaining hope and a positive attitude, and providing comfort through touch. Components of personalization were treating the whole person and not just the disease, making the patient feel unique and special, and considering the patient's social situation. Although the levels of emotional support and personalization varied, there was a minimal level, defined by compassion and treating the whole person and not just the disease, that physicians should strive to meet in caring for all dying patients. Participants also identified intermediate and advanced levels of physician behavior that provide emotional and personal support.

Quality indicators for end-of-life care in the intensive care unit.

OBJECTIVE: The primary goal of this study was to address the documented deficiencies in end-of-life care (EOLC) in intensive care unit settings by identifying key EOLC domains and related quality indicators for use in the intensive care unit through a consensus process. A second goal was to propose specific clinician and organizational behaviors and interventions that might be used to improve these EOLC quality indicators. PARTICIPANTS: Participants were the 36 members of the Robert Wood Johnson Foundation (RWJF) Critical Care End-of-Life Peer Workgroup and 15 nurse-physician teams from 15 intensive care units affiliated with the work group members. Fourteen adult medical, surgical, and mixed intensive care units from 13 states and the District of Columbia in the United States and one mixed intensive care unit in Canada were represented. METHODS: An in-depth literature review was conducted to identify articles that assessed the domains of quality of EOLC in the intensive care unit and general health care. Consensus regarding the key EOLC domains in the intensive care unit and quality performance indicators within each domain was established based on the review of the literature and an iterative process involving the authors and members of the RWJF Critical Care End-of-Life Peer Workgroup. Specific clinician and organizational behaviors and interventions to address the proposed EOLC quality indicators within the domains were identified through a collaborative process with the nurse-physician teams in 15 intensive care units. MEASUREMENTS AND MAIN RESULTS: Seven EOLC domains were identified for use in the intensive care unit: a) patient- and family-centered decision making; b) communication; c) continuity of care; d) emotional and practical support; e) symptom management and comfort care; f) spiritual support; and g) emotional and organizational support for intensive care unit clinicians. Fifty-three EOLC quality indicators within the seven domains were proposed. More than 100 examples of clinician and organizational behaviors and interventions that could address the EOLC quality indicators in the intensive care unit setting were identified. CONCLUSIONS: These EOLC domains and the associated quality indicators, developed through a consensus process, provide clinicians and researchers with a framework for understanding quality of EOLC in the intensive care unit. Once validated, these indicators might be used to improve the quality of EOLC by serving as the components of an internal or external audit evaluating EOLC continuous quality improvement efforts in intensive care unit settings.

Risk of mortality and heart failure exacerbations associated with inhaled beta-adrenoceptor agonists among patients with known left ventricular systolic dysfunction.

OBJECTIVES: Recent studies suggest that myocardial beta(2)-adrenoceptors may be important in chronic heart failure. We sought to determine if use of selective beta(2)-agonists was associated with hospitalization for heart failure and all-cause mortality. METHODS: We studied a cohort of patients with left ventricular systolic dysfunction (LVSD). The outcome was the first hospitalization with a primary diagnosis of chronic heart failure or death from any cause. The exposure was the average number of beta-agonist canisters filled per month in the 90 days prior to and 15 days after enrollment. RESULTS: Among 1,529 subjects, the relative risk (RR) of chronic heart failure hospital admission associated with inhaled beta-agonists followed a dose-response relationship: RR for one canister per month, 1.4 (95% confidence interval [CI], 0.9 to 2.0), RR for two canisters per month, 1.7 (95% CI, 1.2 to 2.5), and RR for three canisters per month, 2.1 (95% CI, 1.4 to 3.1). The RR of death demonstrated a similar finding: RR for one canister per month, 0.9 (95% CI, 0.5 to 1.5), RR for two canisters per month, 1.3 (95% CI, 0.9 to 2.1), and RR for three canisters per month, 2.0 (95% CI, 1.3 to 3.1). Adjusting for potential confounding factors did not affect the estimates. CONCLUSION: Among subjects with LVSD, inhaled beta-agonists were associated with an increased risk of heart failure hospitalization, and all-cause mortality. Clinicians should carefully consider the etiology of dyspnea when prescribing beta-agonists to patients with LVSD.

A measure of the quality of dying and death. Initial validation using after-death interviews with family members.

A reliable and valid measure of the quality of the dying experience would help clinicians and researchers improve care for dying patients. To describe the validity of an instrument assessing the quality of dying and death using the perspective of family members after death and to identify clinical correlates of a high quality death, a retrospective cohort study evaluated the 31-item Quality of Dying and Death (QODD) questionnaire. The questionnaire was administered to family members of patients who died in Missoula county Montana in 1996 and 1997. The interview included questions assessing symptoms, patient preferences, and satisfaction with care. Measurement validity was examined for item and total scores and reliability analyses for the QODD total score were assessed. Construct validity was assessed using measures of concepts hypothesized to be associated with the quality of dying and death. There were 935 deaths, of which 252 (27.0%) family interviews were represented. Non-enrolled decedents were not significantly different from enrolled decedents on age, sex, cause of death, or location of death. We excluded sudden deaths (n = 45) and decedents under age 18 (n = 2), leaving 205 after-death interviews. A total QODD score, on a scale from 0 to 100 with higher scores indicating better quality, ranged from 26.0 to 99.6, with a mean of 67.4 and Cronbach's alpha of 0.89. The total QODD score was not associated with patient age, sex, education, marital status, or income. As hypothesized, higher QODD scores were significantly associated with death at home (P < 0.01), death in the location the patient desired (P < 0.01), lower symptom burden (P < 0.001), and better ratings of symptom treatment (P< 0.01). Although the total score was not associated with the presence of an advance directive, higher scores were associated with communication about treatment preferences (P < 0.01), compliance with treatment preferences (P < 0.001), and family satisfaction regarding communication with the health care team (P < 0.01). Availability of a health care team member at night or on weekends was also associated with a higher QODD score (P < 0.001). The QODD total score demonstrated good cross-sectional validity. Clinicians caring for dying patients should focus on improving communication with the patient and family and improving symptom assessment and treatment. Health care teams should focus on continuity of care, including having a team member familiar with the patient available for calls at nights and on weekends. Future work will assess the potential role of the QODD in improving the quality of the dying experience.

Studying communication about end-of-life care during the ICU family conference: development of a framework.

PURPOSE: Family-clinician communication in the intensive care unit (ICU) about withholding and withdrawing life support occurs frequently, yet few data exist to guide clinicians in its conduct. The purpose of this study was to develop an understanding of the way this communication is currently conducted. METHODS: We identified family conferences in the ICUs of 4 Seattle-area hospitals. Conferences were eligible if the physician leading the conference believed that discussion about withholding or withdrawing life support or the delivery of bad news was likely to occur and if all conference participants consented to participate. Fifty conferences were audiotaped, transcribed, and analyzed by using the principles of grounded theory. RESULTS: We developed 2 frameworks for describing and understanding this communication. The first framework describes communication content, including introductions, information exchange, discussions of the future, and closings. The second framework describes communication styles and support provided to families and other clinicians and includes a variety of techniques such as active listening, acknowledging informational complexity and emotional difficulty of the situation, and supporting family decision making. These frameworks identify what physicians discuss, how they present and respond to issues, and how they support families during these conferences. CONCLUSIONS: This article describes a qualitative methodology to understand clinician-family communication during the ICU family conference concerning end-of-life care and provides a frame of reference that may help guide clinicians who conduct these conferences. We also identify strategies clinicians use to improve communication and enhance the support provided. Further analyses and studies are needed to identify whether this framework or these strategies can improve family understanding or satisfaction or improve the quality care in the ICU.

Effectiveness of screening examinations to detect unrecognized exercise-induced bronchoconstriction.

OBJECTIVE: To determine if a physician-administered physical examination and screening questionnaire accurately detects exercise-induced bronchoconstriction (EIB) in adolescent athletes. STUDY DESIGN: Cross-sectional study of 256 adolescents participating in organized sports from 3 suburban high schools. The number of persons screened positive for EIB by physical examination and questionnaire was compared with the number of persons with EIB diagnosed by a "gold standard" test that consisted of a 7-minute exercise challenge followed by serial spirometry. RESULTS: We diagnosed EIB in 9.4% of adolescent athletes. The screening history identified persons with symptoms or a previous diagnosis suggestive of EIB in 39.5% of the participants, but only 12.9% of these persons actually had EIB. Among adolescents with a negative review of symptoms of asthma or EIB, 7.8% had EIB. Among adolescents with no previous diagnosis of asthma, allergic rhinitis, or EIB, 7.2% had EIB diagnosed by exercise challenge. Persons who screened negative on all questions about symptoms or history of asthma, EIB, and allergic rhinitis accounted for 45.8% of the adolescents with EIB. CONCLUSIONS: EIB occurs frequently in adolescent athletes, and screening by physical examination and medical history does not accurately detect it.

A good death: a qualitative study of patients with advanced AIDS.

The objective of this study was to identify and describe the domains that define a "good" versus "bad" death from the perspective of patients with advanced AIDS. We analyzed qualitative data from face-to-face interviews with 35 patients with C3 AIDS. An experienced research interviewer asked the patients to describe a good and bad death. Investigators used the principles of grounded theory to analyze the interview transcripts and identify the major domains defining a "good" versus a "bad" death. We identified 15 domains, of which 12 were mentioned by at least two participants. The 12 domains include: symptoms, quality of life, people present, dying process, location, a sense of resolution, patient control of treatment, issues of spirituality, death scene, physician-assisted suicide, aspects of medical care, and acceptance of death. Within these, we identified 38 sub-categories representing specific aspects of the domains that shape a "good" versus "bad" death for the patients in this study. The identified 12 major domains encompass the major determinants of a "good" versus "bad" death from the perspective of patients with advanced AIDS. A better understanding of these domains may enable clinicians to more fully appreciate the experiences of their dying patients and identify ways to improve the care they provide at the end of life.

Association between inhaled beta-agonists and the risk of unstable angina and myocardial infarction.

BACKGROUND: beta-Adrenoceptor agonists (beta-agonists) are commonly used to treat obstructive lung diseases, and preliminary studies have suggested they are associated with an increased risk of adverse cardiovascular outcomes. We further examined the association between acute coronary syndromes and inhaled beta-agonist therapy. METHODS: We performed a nested, case-control study using data that were collected as part of a larger, ongoing, prospective study of quality improvement in the primary care clinics of seven Veterans Administration Medical Centers. We identified 630 patients with unstable angina or acute myocardial infarction hospitalized between 1996 and 1999. We frequency matched these case patients to 10,486 control subjects according to clinic location, and randomly assigned each an "index date." The computerized pharmacy database at each center was used to ascertain beta-agonist use. Cardiovascular risk factors were assessed from mailed questionnaires and electronic medical records, which included inpatient and outpatient diagnoses, medications, and laboratory results. RESULTS: In comparison with patients who had not filled a beta-agonist prescription during the 90 days prior to their index date, patients who had filled a beta-agonist prescription had an increased risk of experiencing an acute coronary syndrome. The increased risk of an acute coronary syndrome persisted after adjusting for age and cardiovascular risk factors, including hypertension, diabetes, and smoking history. Moreover, there was a dose-response relationship with an adjusted odds ratio (OR) of 1.38 for one to two metered-dose inhaler (MDI) canisters (95% confidence interval [CI], 0.86 to 2.23), an OR of 1.57 for three to five MDI canisters (95% CI, 1.01 to 2.46), and an OR of 1.93 for six or more MDI canisters (95% CI, 1.23 to 3.03). After stratifying for receipt of a beta-blocker prescription, the adjusted OR in subjects who did not receive a beta-blocker was 1.55 for one to two MDI canisters (95% CI, 0.60 to 3.99), an OR of 4.07 for three to five canisters (95% CI, 2.17 to 7.64), and an OR of 3.83 for six or more canisters (95% CI, 2.02 to 7.29). Subjects who had received both beta-blockers and beta-agonists had no increase in risk in acute coronary syndromes unless they had filled six or more beta-agonist MDI canisters. CONCLUSIONS: A prescription for inhaled beta-agonists may increase the risk of myocardial infarction and unstable angina in patients with COPD.

Patients' perspectives on physician skill in end-of-life care: differences between patients with COPD, cancer, and AIDS.

OBJECTIVES: Patients' views of physician skill in providing end-of-life care may vary across different diseases, and understanding these differences will help physicians improve the quality of care they provide for patients at the end of life. The objective of this study was to examine the perspectives of patients with COPD, cancer, or AIDS regarding important aspects of physician skill in providing end-of-life care. DESIGN: Qualitative study using focus groups and content analysis based on grounded theory. SETTING: Outpatients from multiple medical settings in Seattle, WA. PATIENTS: Eleven focus groups of 79 patients with three diseases: COPD (n = 24), AIDS (n = 36), or cancer (n = 19). RESULTS: We identified, from the perspectives of patients, the important physician skills for high-quality end-of-life care. Remarkable similarities were found in the perspectives of patients with COPD, AIDS, and cancer, including the importance of emotional support, communication, and accessibility and continuity. However, each disease group identified a unique theme that was qualitatively more important to that group. For patients with COPD, the domain concerning physicians' ability to provide patient education stood out as qualitatively and quantitatively more important. Patients with COPD desired patient education in five content areas: diagnosis and disease process, treatment, prognosis, what dying might be like, and advance care planning. For patients with AIDS, the unique theme was pain control; for patients with cancer, the unique theme was maintaining hope despite a terminal diagnosis. CONCLUSIONS: Patients with COPD, AIDS, and cancer demonstrated many similarities in their perspectives on important areas of physician skill in providing end-of-life care, but patients with each disease identified a specific area of end-of-life care that was uniquely important to them. Physicians and educators should target patients with COPD for efforts to improve patient education about their disease and about end-of-life care, especially in the areas defined above. Physicians caring for patients with advanced AIDS should discuss pain control at the end of life, and physicians caring for patients with cancer should be aware of many patients' desires to maintain hope. Physician understanding of these differences will provide insights that allow improvement in the quality of care.

Using quality of life to predict hospitalization and mortality in patients with obstructive lung diseases.

STUDY OBJECTIVES: Condition-specific measures of quality of life (QOL) for patients with COPD have been demonstrated to be highly reliable and valid, but they have not conclusively been shown to predict hospitalization or death. OBJECTIVE: We sought to determine whether a brief, self-administered, COPD-specific QOL measure, the Seattle Obstructive Lung Disease Questionnaire (SOLDQ), could accurately predict hospitalizations and death. DESIGN: Prospective cohort study. SETTING: Patients enrolled in the primary care clinics at seven Department of Veterans Affairs (VA) medical centers participating in the Ambulatory Care Quality Improvement Project. PATIENTS: Of 24,458 patients who completed a health inventory, 5,503 reported having chronic lung disease. The 3,282 patients who completed the baseline SOLDQ were followed for 12 months. MEASUREMENTS: Hospitalization and all-cause mortality during the 1-year follow-up period. RESULTS: During the follow-up period, 601 patients (18.3%) were hospitalized, 141 (4.3%) for COPD exacerbations, and 167 patients (5.1%) died. After adjusting for age, VA hospital site, distance to the VA hospital, employment status, and smoking status, the relative risk of any hospitalization among patients with scores on the emotional, physical, and coping skills scales of the SOLDQ that were in the lowest quartile, when compared to the highest quartile, were 2.0 (95% confidence interval [CI], 1.5 to 2.6), 2.5 (95% CI, 1.9 to 3.4), and 1.9 (95% CI, 1.5 to 2.5), respectively. When hospitalizations were restricted to those specifically for COPD, the odds ratio (OR) for the lowest quartile of physical function was 6.0 (95% CI, 3.1 to 11.5). Similarly, patients in the lowest quartile of physical function also had an increased risk of death (OR, 6.8; 95% CI, 3.3 to 13.8). When adjusted for comorbidity (OR, 0.8; 95% CI, 0.5 to 1.2), long-term steroid use (OR, 2.8; 95% CI, 1.6 to 4.9), and prior hospitalization for COPD (OR, 4.5; 95% CI, 2.2 to 9.2), patients having baseline SOLDQ physical function scores in the lowest quartile had an odds of hospitalization for COPD that was fivefold higher than patients with scores in the highest quartile (OR, 5.0; 95% CI, 2.6 to 9.7). CONCLUSIONS: Lower QOL is a powerful predictor of hospitalization and all-cause mortality. Brief, self-administered instruments such as the SOLDQ may provide an opportunity to identify patients who could benefit from preventive interventions.
