Sudden hospital closures displace patients from usual sources of care and force them to access facilities that lack their prior medical records. For patients with complex needs and for nearby hospitals already strained by high volume, disaster-related hospital closures induce a public health emergency. Our objective was to analyze responses of patients from public versus private emergency departments after closure of their usual hospital after Hurricane Sandy. Using a statewide database of emergency visits, we followed patients with an established pattern of accessing 1 of 2 hospitals that closed after Hurricane Sandy: Bellevue Hospital Center and NYU Langone Medical Center. We determined how these patients redistributed for emergency care after the storm. We found that proximity strongly predicted patient redistribution to nearby open hospitals. However, for patients from the closed public hospital, this redistribution was also influenced by hospital ownership, because patients redistributed to other public hospitals at rates higher than expected by proximity alone. This differential response to hospital closures demonstrates significant differences in how public and private patients respond to changes in health care access during disasters. Public health response must consider these differences to meet the needs of all patients affected by disasters and other public health emergencies.

High-dose methotrexate (MTX) can produce acute kidney injury, impairing MTX elimination. Continuous venovenous hemofiltration (CVVH) may enhance elimination in this setting, although its use is largely unstudied. A 79-year-old man received IV MTX for central nervous system lymphoma, and over a 34-h period his serum creatinine increased from 1.09 to 2.24 mg/dL. His serum MTX concentration (sMTX) at the end of this time period was 59.05 micromol/L. After urinary alkalinization and leucovorin and glucarpidase (CPDG2) treatment, sMTX decreased. Fluid overload ensued and CVVH was initiated. The initial MTX extraction ratio and clearance were 0.22 and 47.0 mL/min, respectively. No MTX extraction occurred at an sMTX of 0.15 micromol/L. Continuous venovenous hemodialysis was initiated, and sMTX further declined. CVVH may help eliminate MTX and provide renal replacement at moderate sMTX.

A freestanding, 911-receiving emergency department was implemented at Bellevue Hospital Center during the recovery efforts after Hurricane Sandy to compensate for the increased volume experienced at nearby hospitals. Because inpatient services at several hospitals remained closed for months, emergency volume increased significantly. Thus, in collaboration with the New York State Department of Health and other partners, the Health and Hospitals Corporation and Bellevue Hospital Center opened a freestanding emergency department without on-site inpatient care. The successful operation of this facility hinged on key partnerships with emergency medical services and nearby hospitals. Also essential was the establishment of an emergency critical care ward and a system to monitor emergency department utilization at affected hospitals. The results of this experience, we believe, can provide a model for future efforts to rebuild emergency care capacity after a natural disaster such as Hurricane Sandy.

The effects of chemotherapy in multiple organ systems may be challenging to discern from the sequelae of malignancy and systemic illnesses with concomitant immunocompromise. Chemotherapeutic agents typically affect multiple organ systems. Intrathecal medication errors may pose particularly devastating neurologic consequences and death, often requiring emergent intervention. This article provides an overview of commonly used chemotherapeutic drugs, indications for use, their adverse effects by organ system, and the management of commonly encountered toxicities. Intrathecal medication errors and specific antidotes are discussed in pertinent management sections. Emergency department management should focus on rapid patient assessment, immediate intervention following intrathecal medication errors, exclusion of infection, and excellent supportive care.
