RESUMEN

Policy and financial pressures have driven up use of observation stays for patients in traditional Medicare and the Veterans' Affairs Healthcare System. Using claims data (2004-2014) from OptumLabs™ Data Warehouse, we examined whether people in private Medicare Advantage (MA) and commercial plans experienced similar changes. We found that use of observation increased rapidly for patients in MA plans-even though MA plans were not subject to the same pressures as government-run programs. In contrast, use of observation remained constant for people in commercial plans-except for enrollees 65 and older, for whom it increased somewhat. Privately insured patients returning to the hospital after an inpatient stay were increasingly likely to be placed under observation. Our results suggest that observation is rapidly replacing inpatient admissions and readmissions for many older patients in MA and commercial plans, while younger patients continue to be admitted as inpatients at relatively constant rates.

RESUMEN

BACKGROUND: Shared decision making in the emergency department (ED) can increase patient engagement for patients presenting with chest pain. However, little is known regarding which factors are associated with actual patient involvement in decision making or patients' desired involvement in emergency care decisions. We examined which factors were associated with patients' actual and desired involvement in decision making among ED chest pain patients. METHODS: This is a secondary analysis of data from a randomized trial of a shared decision-making intervention in ED patients with low-risk chest pain. We evaluated the degree to which patients were involved in decision making using the OPTION-12 (observing patient involvement) scale and patients' reported desire for involvement in decision making using the Control Preferences Scale (CPS). We measured the associations of patient factors with OPTION-12 and CPS scores using multivariable regression. RESULTS: Of the 898 patients enrolled, mean (±SD) age was 51.5 (±11.4) years and 59% were female. Multivariable analysis revealed that only two factors were significantly associated with OPTION-12 scores: study site and use of the decision aid. OPTION-12 scores were 10.3 (standard error = 0.6) points higher for patients randomized to the decision aid compared to usual care (p < 0.001). Higher health literacy was associated with lower scores on the CPS, indicating greater desire for involvement (odds ratio = 0.91, p < 0.001). CONCLUSIONS: Patients' reported desire for involvement in decision making was higher among those with higher health literacy. After study site and other potential confounding factors were adjusted for, only use of the decision aid was associated with observed patient involvement in decision making. As the science and practice of shared decision making in the ED moves toward implementation, high-fidelity integration of the decision aid into the flow of care will be necessary to realize desired outcomes.

RESUMEN

OBJECTIVES: Neurovascular and neurocritical care emergencies constitute a leading cause of morbidity/mortality. There has been great evolution in this field, including but not limited to extended time-window therapeutic interventions for acute ischemic stroke. The intent of this article is to evaluate the goals and future direction of clinical rotations in neurovascular and neurocritical care for emergency medicine (EM) residents. METHODS: A panel of 13 board-certified emergency physicians from the Society for Academic Emergency Medicine (SAEM) neurologic emergencies interest group (IG) convened in response to a call for publications-three with fellowship training/board certification in stroke and/or neurocritical care; five with advanced research degrees; three who have been authors on national practice guidelines; and six who have held clinical duties within neurology, neurosurgery, or neurocritical care. A mixed-methods analysis was performed including a review of the literature, a survey of Council of Emergency Medicine Residency Directors (CORD) residency leaders/faculty and SAEM neuro-IG members, and a consensus review by this panel of select neurology rotations provided by IG faculty. RESULTS: Thirteen articles for residency neurovascular education were identified: three studies on curriculum, three studies evaluating knowledge, and seven studies evaluating knowledge after an educational intervention. Intervention outcomes included the ability to recognize and manage acute strokes, manage intracerebral hemorrhage, calculate National Institutes of Health Stroke Scale (NIHSS), and interpret images. In the survey sent to CORD residency leaders and neuro-IG faculty, response was obtained from 48 programs. A total of 52.1% indicated having a required rotation (6.2% general neurology, 2% stroke service, 18.8% neurologic intensive care unit, 2% neurosurgery, 22.9% on a combination of services). The majority of programs with required rotations have a combination rotation (residents rotate through multiple services) and evaluations were positive. CONCLUSIONS: Variability exists in the availability of neurovascular/neurocritical care rotations for EM trainees. Dedicated clinical time in neurologic education was beneficial to participants. Given recent advancements in the field, augmentation of EM residency training in this area merits strong consideration.

RESUMEN

BACKGROUND: Motor vehicle-related injuries (including off-road) are the leading cause of traumatic brain injury (TBI) and acute traumatic spinal cord injury in the United States. OBJECTIVES: To describe motocross-related head and spine injuries of adult patients presenting to an academic emergency department (ED). METHODS: We performed an observational cohort study of adult ED patients evaluated for motocross-related injuries from 2010 through 2015. Electronic health records were reviewed and data extracted using a standardized review process. RESULTS: A total of 145 motocross-related ED visits (143 unique patients) were included. Overall, 95.2% of patients were men with a median age of 25years. Sixty-seven visits (46.2%) were associated with head or spine injuries. Forty-three visits (29.7%) were associated with head injuries, and 46 (31.7%) were associated with spine injuries. Among the 43 head injuries, 36 (83.7%) were concussions. Seven visits (16.3%) were associated with at least 1 head abnormality identified by computed tomography, including skull fracture (n=2), subdural hematoma (n=1), subarachnoid hemorrhage (n=4), intraparenchymal hemorrhage (n=3), and diffuse axonal injury (n=3). Among the 46 spine injuries, 32 (69.6%) were acute spinal fractures. Seven patients (4.9%) had clinically significant and persistent neurologic injuries. One patient (0.7%) died, and 3 patients had severe TBIs. CONCLUSION: Adult patients evaluated in the ED after motocross trauma had high rates of head and spine injuries with considerable morbidity and mortality. Almost half had head or spine injuries (or both), with permanent impairment for nearly 5% and death for 0.7%.

RESUMEN

OBJECTIVES: The authors previously derived a clinical decision rule (CDR) for chest radiography in patients with chest pain and possible acute coronary syndrome (ACS) consisting of the absence of three predictors: history of congestive heart failure, history of smoking, and abnormalities on lung auscultation. The aim of the investigation was to prospectively validate and refine the CDR for chest radiography in an independent patient population. METHODS: Patients over 24 years of age with a primary complaint of chest pain and possible ACS were prospectively enrolled from September 2008 to January 2010 at an academic emergency department (ED) with 73,000 annual patient visits. Physicians completed standardized data collection forms before ordering chest radiographs. Two investigators, blinded to the data collection forms, independently classified chest radiographs as "normal,""abnormal not requiring intervention," or "abnormal requiring intervention" (e.g., heart failure, infiltrates), based on review of the radiology report and medical record. Analyses included descriptive statistics, interrater reliability assessment (kappa), and recursive partitioning. RESULTS: Of 1,159 visits for possible ACS in which chest radiography was obtained, mean (±SD) age was 60.3 (±15.6) years, and 51% were female. Twenty-four percent had a history of acute myocardial infarction, 10% congestive heart failure, and 11% atrial fibrillation. Sixty-nine (6.0%, 95% confidence interval [CI] = 4.7% to 7.5%) patients had a radiographic abnormality requiring intervention. The kappa statistic for chest radiograph classification was 0.93 (95% CI = 0.88 to 0.97). The previously derived prediction rule (no history of congestive heart failure, no history of smoking, and no abnormalities on lung auscultation) was 78.3% sensitive (95% CI = 67.2% to 86.4%) and 45.1% specific (95% CI = 42.2% to 48.1%) and had a positive predictive value of 8.3% (95% CI = 6.4% to 10.7%) and a negative predictive value of 97.0% (95% CI = 95.2% to 98.2%). Due to suboptimal performance, the rule was refined. The refined rule (no shortness of breath, no history of smoking, no abnormalities on lung auscultation, and age < 55 years) was 100.0% sensitive (95% CI = 93.4% to 100.0%) and 11.5% specific (95% CI = 9.6% to 13.5%) and had a positive predictive value of 6.7% (95% CI = 5.3% to 8.4%) and a negative predictive value of 100.0% (95% CI = 96.3% to 100.0%). CONCLUSIONS: Prospective validation of our previously derived CDR for clinically important chest radiographic abnormalities was not successful. Derivation of a refined rule identified all clinically important radiographic abnormalities, but was insufficiently specific. No CDR with adequate sensitivity and specificity could be found.
