Sepsis and Acute Myeloid Leukemia: A Population-Level Study of Comparative Outcomes of Patients Discharged From Texas Hospitals.

BACKGROUND: In the United States, approximately 750,000 cases of sepsis occur annually, and 28% to 50% of affected people die. Treatment is costly, often involving admission to the intensive care unit and prolonged hospitalization. We evaluated outcomes of patients with acute myeloid leukemia (AML) and sepsis in Texas. PATIENTS AND METHODS: We conducted a population-based cohort study of adults discharged from Texas hospitals during 2011, using ICD-9-CM codes and the Texas Inpatient Data Collection. RESULTS: A total of 2,173,776 adults were discharged from hospitals in Texas, and 5501 (0.25%) had a diagnosis of AML. Among patients with AML, 40% were ≥ 65 years old, and 52% were men. The rate of sepsis for AML patients was 16% compared to 4% for non-AML patients. Among patients with AML, sepsis was associated with pneumonia, acute renal failure, and hematologic dysfunctions in 34%, 32%, and 29% of discharges, respectively. Median length of stay, intensive care unit admission rate, and median hospital charges per stay for patients with AML and sepsis were 13 days (range, 1-133 days), 72%, and $122,333, respectively. Among in-hospital deaths due to sepsis, mortality was 30% in AML patients compared to 21% in non-AML patients. CONCLUSION: Patients with AML had a higher sepsis incidence and higher mortality rates overall, especially in relation to stem-cell transplant recipients and those with other types of cancer. Clinical trials are needed to determine whether early intervention or treatment in specialized centers could improve outcomes and reduce costs of care, particularly in the management of serious complications such as sepsis.

Acute Respiratory Failure Induced by Magnesium Replacement in a 62-Year-Old Woman with Myasthenia Gravis.

Magnesium is known to act at the neuromuscular junction by inhibiting the presynaptic release of acetylcholine and desensitizing the postsynaptic membrane. Because of these effects, magnesium has been postulated to potentiate neuromuscular weakness. We describe the case of a 62-year-old woman with myasthenia gravis and a metastatic thymoma who was admitted to our intensive care unit for management of a myasthenic crisis. The patient's neuromuscular weakness worsened in association with standard intravenous magnesium replacement, and the exacerbated respiratory failure necessitated intubation, mechanical ventilation, and an extended stay in the intensive care unit. The effect of magnesium replacement on myasthenia gravis patients has not been well documented, and we present this case to increase awareness and stimulate research. In addition, we discuss the relevant medical literature.

Implementation of modified early-goal directed therapy for sepsis in the emergency center of a comprehensive cancer center.

PURPOSE: The investigation examines the impact of a standardized sepsis order set and algorithm utilizing non-invasive monitoring for early-goal directed therapy (EGDT) in an emergency center setting on the clinical outcomes of sepsis in cancer patients. METHODS: Single-center, retrospective study comparing clinical outcomes of sepsis before and after routine usage of a standardized order set and algorithm for non-invasive elements of EGDT for sepsis in an emergency center of a comprehensive cancer center. The outcomes measures evaluated were 28-day in-hospital mortality, intensive care unit length of stay, hospital length of stay, goal mean arterial pressure and urine output within the first 6 h of treatment, time to measurement of lactic acid, and appropriateness and timeliness of initial antibiotic therapy. RESULTS: The 28-day in-hospital mortality was significantly lower in the post-intervention group compared to the pre-intervention group (20 vs. 38%, p = 0.005). The percentages of patients who reached their goal mean arterial pressure (74 vs. 90%, p = 0.004) and goal urine output (79 vs. 96%, p = 0.002) during the first 6 h of treatment were higher the after than the before group. No significant differences were detected in the rest of the outcome measures. CONCLUSIONS: Implementation of a standardized sepsis order set and algorithm to improve compliance with the non-invasive elements of EGDT for sepsis in cancer patients in the emergency center setting was associated with a decreased 28-day in-hospital mortality rate.
