Early Anticoagulation Is Associated With Reduced Mortality for Acute Pulmonary Embolism

BACKGROUND Acute pulmonary embolism (PE) may be rapidly fatal if not diagnosed and treated. IV heparin reduces mortality and recurrence of PE, but the relationship between survival and timing of anticoagulation has not been extensively studied. METHODS We studied 400 consecutive patients in the ED diagnosed with acute PE by CT scan angiography and treated in the hospital with IV unfractionated heparin from 2002 to 2005. Patients received heparin either in the ED or after admission. Time from ED arrival to therapeutic activated partial thromboplastin time (aPTT) was calculated. Outcomes included in-hospital and 30-day mortality, hospital and ICU lengths of stay, hemorrhagic events on heparin, and recurrent venous thromboembolism within 90 days. RESULTS In-hospital and 30-day mortality rates were 3.0% and 7.7%, respectively. Patients who received heparin in the ED had lower in-hospital (1.4% vs 6.7%; P = .009) and 30-day (4.4% vs 15.3%; P < .001) mortality rates as compared with patients given heparin after admission. Patients who achieved a therapeutic aPTT within 24 h had lower in-hospital (1.5% vs 5.6%; P = .093) and 30-day (5.6% vs 14.8%; P = .037) mortality rates as compared with patients who achieved a therapeutic aPTT after 24 h. In multiple logistic regression models, receiving heparin in the ED remained predictive of reduced mortality, and ICU admission remained predictive of increased mortality. CONCLUSIONS We report an association between early anticoagulation and reduced mortality for patients with acute PE. We advocate further study with regard to comorbidities to assess the usefulness of modifications to hospital protocols.

Dyspnea Review for the Palliative Care Professional: Treatment Goals and Therapeutic Options

Although dyspnea is frequently encountered in the palliative care setting, its optimal management remains uncertain. Clinical approaches begin with accurate assessment, as delineated in part one of this two-part series. Comprehensive dyspnea assessment, which encompasses the physical, emotional, social, and spiritual aspects of this complex symptom, guide the clinician in choosing therapeutic approaches herein presented as part two. Global management of dyspnea is appropriate both as complementary to disease-targeted treatments that target the underlying etiology, and as the sole focus when the symptom has become intractable, disease is maximally treated, and goals of care shift to comfort and quality of life. In this setting, current evidence supports the use of oral or parenteral opioids as the mainstay of dyspnea management, and of inhaled furosemide and anxiolytics as adjuncts. Nonpharmacologic interventions such as acupuncture and pulmonary rehabilitation have potential effectiveness, although further research is needed, and use of a simple fan warrants consideration given its potential benefit and minimal burden and cost.

Quality Measures for Palliative Care in Patients With Cancer: A Systematic Review

PURPOSE Quality assessment is a critical component of determining the value of medical services, including palliative care. Characterization of the current portfolio of measures that assess the quality of palliative care delivered in oncology is necessary to identify gaps and inform future measure development. METHODS We performed a systematic review of MEDLINE/PubMed and the gray literature for quality measures relevant to palliative care. Measures were categorized into National Quality Forum domains and reviewed for methodology of development and content. Measures were additionally analyzed to draw summative conclusions on scope and span. RESULTS Two hundred eighty-four quality measures within 13 measure sets were identified. The most common domains for measure content were Physical Aspects of Care (35%) and Structure and Processes of Care (22%). Of symptom-related measures, pain (36%) and dyspnea (26%) were the most commonly addressed. Spiritual (4%) and Cultural (1%) Aspects of Care were least represented domains. Generally, measures addressed processes of care, did not delineate benchmarks for success, and often did not specify intended interventions to address unmet needs. This was most evident regarding issues of psychosocial and spiritual assessment and management. CONCLUSION Within a large cohort of quality measures for palliative, care is often a focus on physical manifestations of disease and adverse effects of therapy; relatively little attention is given to the other aspects of suffering commonly observed among patients with advanced cancer, including psychological, social, and spiritual distress.

Strategies to combat chronic critical illness.

Purpose of reviewThe population of chronically critically ill patients is growing as advances in intensive care management improve survival from the acute phase of critical illness. These patients are characterized by complex medical needs and heavy resource utilization. This article reviews evidence supporting a comprehensive approach to the prevention and management of chronic critical illness (CCI). Recent findingsThe most efficient approach to weaning patients with CCI at long-term acute care hospitals is daily unassisted breathing trials through a tracheostomy collar. However, a substantial number of patients transferred to long-term acute care hospitals pass their spontaneous weaning trials. Transfer to long-term acute care hospitals is associated with higher acute care costs and payments, but lower costs through the entire episode of illness. Universal decontamination is more effective than targeted decontamination or screening and isolation for preventing nosocomial bloodstream infections. SummaryCombating CCI begins with prevention in the acute phase of illness. Management strategies include a spectrum of ventilatory, nutritional, and rehabilitation support. Further patient-centered outcome-based research in this specific population is needed to continue to help guide optimal care.

Priorities for Evaluating Palliative Care Outcomes in Intensive Care Units

Defining the quality of intensive care unit (ICU) care when patients are dying is challenging. Palliative care has been recommended to improve outcomes of dying ICU patients; however, traditional ICU quality indicators do not always align with palliative care. Evidence suggests that some aspects of ICU care improve when palliative care is integrated; however, consensus is lacking concerning the outcomes that should be measured. Overcoming challenges to measuring palliative care will require consensus development and rigorous research on the best way to evaluate ICU palliative care services.

Clinical Cases in Acute Intoxication

Abstract Over 2.5 million accidental and intentional drug-related poisonings are reported annually in the United States. Early diagnosis and management of patients who present with acute intoxication can significantly reduce both morbidity and mortality. The initial evaluation of patients with suspected or proven intoxications should focus on hemodynamic stability, mental status, and respiratory function. However, early recognition of toxic ingestion is paramount to implementing life-saving treatments. Important historical clues are often found in a social history that considers intravenous drug use, alcohol use, and any access or exposure to illicit substances. A patients medication list should also be scrutinized for psychoactive or sedative medications, such as tricyclic antidepressants or opioids. In this article we present case-based discussions of the specific diagnosis and management of 5 commonly occurring acute intoxication syndromes.
