Introduction: National health security requires that healthcare facilities be prepared to provide rapid,effective emergency and trauma care to all patients affected by a catastrophic event. We sought toquantify changes in healthcare utilization patterns for an at-risk Medicare population before, during,and after Superstorm Sandy’s 2012 landfall in New Jersey (NJ).

Methods: This study is a retrospective cohort study of Medicare beneficiaries impacted bySuperstorm Sandy. We compared hospital emergency department (ED) and healthcare facilityinpatient utilization in the weeks before and after Superstorm Sandy landfall using a 20%random sample of Medicare fee-for-service beneficiaries continuously enrolled in 2011 and 2012(N=224,116). Outcome measures were pre-storm discharges (or transfers), average length of stay,service intensity weight, and post-storm ED visits resulting in either discharge or hospital admission.

Results: In the pre-storm week, hospital transfers from skilled nursing facilities (SNF) increased by39% and inpatient discharges had a 0.3 day decreased mean length of stay compared to the prioryear. In the post-storm week, ED visits increased by 14% statewide; of these additional “surge”patients, 20% were admitted to the hospital. The increase in ED demand was more than double thestatewide average in the most highly impacted coastal regions (35% versus 14%).

Conclusion: Superstorm Sandy impacted both pre- and post-storm patient movement in NewJersey; post-landfall ED surge was associated with overall storm impact, which was greatest incoastal counties. A significant increase in the number and severity of pre-storm transfer patients,in particular from SNF, as well as in post-storm ED visits and inpatient admissions, draws attentionto the importance of collaborative regional approaches to healthcare in large-scale events.

Ocular trauma is one of the most common and vision-threatening ophthalmic presentations with a wide spectrum of complications, such as bleeding, infection, vision loss, and enucleation. A 64-year-old-male presented to the emergency department (ED) with a self-inflicted orbital penetrating injury with a hair comb. Computed tomography showed the comb traversed the medial orbit inferior to the medial rectus but did not damage the optic nerve; there were no globe or orbital wall fractures. His ocular exam was significant for a right eye afferent pupillary defect and decreased visual acuity 20/800, consistent with optic neuropathy. Primary concerns were stabilizing and removing the foreign body without causing further damage in the setting of an uncooperative patient. The comb was removed with the aid of local and systemic analgesia using gentle traction and normal saline irrigation. The patient was admitted for systemic and topical antibiotics and showed improvement in visual acuity and resolution of his optic neuropathy. This case illustrates the importance of rapid ED assessment and management of complex penetrating ocular trauma. Examination should specifically look for signs of globe rupture and optic nerve injury. Expedited foreign body removal should be managed together with an ophthalmologist with procedural sedation and broad-spectrum antibiotics to avoid further visual and infectious complications.

Introduction: International Classification of Disease, Ninth Revision (ICD-9) diagnosis codes have not been validated for identifying cases of missed abortion where a pregnancy is no longer viable but the cervical os remains closed. Our goal was to assess whether ICD-9 code “632” for missed abortion has high sensitivity and positive predictive value (PPV) in identifying patients in the emergency department (ED) with cases of stable early pregnancy failure (EPF).

Methods: We studied females ages 13-50 years presenting to the ED of an urban academic medical center. We approached our analysis from two perspectives, evaluating both the sensitivity and PPV of ICD-9 code “632” in identifying patients with stable EPF. All patients with chief complaints “pregnant and bleeding” or “pregnant and cramping” over a 12-month period were identified. We randomly reviewed two months of patient visits and calculated the sensitivity of ICD-9 code “632” for true cases of stable miscarriage. To establish the PPV of ICD-9 code “632” for capturing missed abortions, we identified patients whose visits from the same time period were assigned ICD-9 code “632,” and identified those with actual cases of stable EPF. Results: We reviewed 310 patient records (17.6% of 1,762 sampled). Thirteen of 31 patient records assigned ICD-9 code for missed abortion correctly identified cases of stable EPF (sensitivity=41.9%), and 140 of the 142 patients without EPF were not assigned the ICD-9 code “632”(specificity=98.6%). Of the 52 eligible patients identified by ICD-9 code “632,” 39 cases met the criteria for stable EPF (PPV=75.0%).

Conclusion: ICD-9 code “632” has low sensitivity for identifying stable EPF, but its high specificity and moderately high PPV are valuable for studying cases of stable EPF in epidemiologic studies using administrative data.

Introduction: Prior studies have reported conflicting results regarding the utility of ultrasound in the diagnosis of traumatic pneumothorax (PTX) because they have used sonologists with extensive experience. This study evaluates the characteristics of ultrasound for PTX for a large cohort of trauma and emergency physicians.

Methods: This was a prospective, observational study on a convenience sample of patients presenting to a trauma center who had a thoracic ultrasound (TUS) evaluation for PTX performed after the Focused Assessment with Sonography for Trauma exam. Sonologists recorded their findings prior to any other diagnostic studies. The results of TUS were compared to one or more of the following: chest computed tomography, escape of air on chest tube insertion, or supine chest radiography followed by clinical observation.

Results: There were 549 patients enrolled. The median injury severity score of the patients was 5 (inter-quartile range [IQR] 1-14); 36 different sonologists performed TUS. Forty-seven of the 549 patients had traumatic PTX, for an incidence of 9%. TUS correctly identified 27/47 patients with PTX for a sensitivity of 57% (confidence interval [CI] 42-72%). There were 3 false positive cases of TUS for a specificity of 99% (CI 98%-100%). A “wet” chest radiograph reading done in the trauma bay showed a sensitivity of 40% (CI 23-59) and a specificity of 100% (99-100).

Conclusion: In a large heterogenous group of clinicians who typically care for trauma patients, the sonographic evaluation for pneumothorax was as accurate as supine chest radiography. Thoracic ultrasound may be helpful in the initial evaluation of patients with truncal trauma. [West J Emerg Med 2013;14(2):103-108.]
