Variations in Safe Sleep Practices and Beliefs: Knowledge is not Enough.

OBJECTIVES: Sleep-related infant deaths in the District of Columbia (DC) varies, with rates in certain geographical areas three times higher than DC and seven times higher than the national average. We sought to understand differences in infant sleep knowledge, beliefs, and practices between families in high-risk infant mortality and low-risk infant mortality areas in DC. METHODS: Caregivers of infants presenting to the emergency department were surveyed. The associations between location and safe sleep knowledge, beliefs, and practices were analyzed. RESULTS: Two hundred and eighty-four caregivers were surveyed; 105 (37%) were from the high-risk infant mortality area. The majority (68%) of caregivers reported placing their infant to sleep on their backs, sleeping in a crib, bassinet, or pack and play (72%), and were familiar with the phrase "safe sleep" (72%). Caregivers from the high-risk infant mortality area were more likely to report that their infants sleep in homes other than their own (aOR 1.53; 95% CI 1.23, 2.81) and other people took care of their infants while sleeping (aOR 1.76; 95% CI 1.17, 3.19), adjusting for race/ethnicity, education, marital status, and help with childcare. No differences in safe sleep knowledge, beliefs, and practices were present. CONCLUSIONS FOR PRACTICE: Infants from the high-risk infant mortality area were more likely to sleep in homes other than their own and have other caretakers while sleeping. Lack of differences in caregiver awareness of safe sleep recommendation or practices suggests effective safe sleep messaging. Outreach to other caregivers and study of unmet barriers is needed.

Characteristics and Geographic Variation in Sudden Unexpected Infant Deaths in the District of Columbia.

ABSTRACT: Sleep-related infant death is a major cause of infant mortality in the United States. In the District of Columbia, infant mortality varies widely among regions (2 to 14 per 1000 live births). The study objectives were to analyze the patient characteristics and related variables to sudden unexpected infant deaths at 2 pediatric emergency department (ED) sites and the geographic patterns of infant deaths and their relationship to social vulnerability. This retrospective cohort study examined infants under 1 year of age presenting with cardiac arrest at 2 ED sites from 2010 to 2020. Analysis showed 81 deaths with a median population age of 75 days (SD, 46 days). The most frequent demographics of deceased patients were African American Black (89%) with Medicaid insurance (63%), born at term gestation (66%), and without comorbidity (60%). The cause of death was most frequently undetermined (32%) and asphyxia (31%). Most cases involved bed-sharing (63%), despite more than half of those cases having a known safe sleep surface available. Infant death location showed that most deaths occurred in areas with the highest social vulnerability index, including near a community ED location. Understanding the etiologies of this geographic variability may enhance sleep-related infant death prevention strategies.

Liquid Nicotine, E-Cigarettes, and Vaping: Information for the Pediatric Emergency Medicine Provider.

ABSTRACT: E-cigarettes, or electronic cigarettes, are electronic nicotine delivery systems that are marketed as a healthier alternative to tobacco cigarettes. There has been an exponential increase in their use among youth since their introduction to the United States market in 2007. With increased use and popularity, there has been an increase in calls to poison control centers regarding liquid nicotine toxicity in children and adolescents. Recent US Food and Drug Administration and other federal regulations of e-cigarettes have attempted to limit availability to youth. This article reviews trends in e-cigarette use among youth, the background and mechanism of action of e-cigarettes, liquid nicotine toxicity, management of liquid nicotine toxicity, and recent policy updates regarding e-cigarettes.

Infant Safe Sleep in the District of Columbia: Better for Both.

Sudden unexpected infant death (SUID) rates within the District of Columbia (DC) vary, with rates 3 times higher in certain geographical areas than the cumulative rate in DC and 7 times higher than the national rate. The majority SUIDs are due to unsafe sleep practices. Although safe sleep education and resources are available in these areas, the high sleep-related infant mortality suggests unmet barriers to infant safe sleep. We sought to investigate potential contributions to local infant mortality through focus groups regarding infant sleep practices among DC caregivers. In this qualitative study, caregivers were probed regarding barriers and facilitators of infant sleep practices. Data were collected until thematic saturation was reached, then coded. Themes were developed and revised in an iterative manner. Fifteen caregivers participated in three focus groups. Themes included sources of infant sleep knowledge, challenges for infant sleep, and motivators for infant sleep choice. All caregivers reported knowledge of safe sleep practices. Infant sleep practices varied, and included unsafe practices such as bed sharing, co-sleeping, and use of swings or bouncers for infant sleep. Challenges of adhering to safe sleep practices included infant needs, competing family demands, the overwhelming nature of newborn sleep, threats, and conflicting information. Motivators for infant sleep practices included better sleep, convenience, safety, tradition, and needs of the infant and caregiver. Although caregivers report knowledge of safe sleep recommendations, actual infant sleep practices vary and include unsafe sleep practices. More focused interventions are needed to address this gap between safe sleep knowledge and practice.

Triple threat: New presentation with diabetic ketoacidosis, COVID-19, and cardiac arrhythmias.

Patients with diabetes have increased susceptibility to infection with Severe acute respiratory syndrome-coronavirus 2 and increased morbidity and mortality from Coronavirus disease 2019 (COVID-19) infection. Mortality from COVID-19 is sometimes caused by cardiac arrhythmias. Electrolyte disturbances in patients with diabetic ketoacidosis (DKA) can increase the risk of cardiac arrhythmias. Despite these correlations, little has been reported about the co-incidence of these three conditions: COVID-19, DKA and cardiac arrhythmias. In this case report we describe two children with COVID-19, new-onset DKA and cardiac arrhythmias. These cases emphasize the importance of close cardiac and electrolyte monitoring in patients with COVID-19 infection.

Dyslipidemia and its association with meibomian gland dysfunction.

Abnormal serum lipid levels significantly increase the risk for cardiovascular disease. Furthermore, abnormal compositions of cholesterol in glandular secretions have been hypothesized as an etiology for meibomian gland dysfunction, yet this relationship has not been well studied in clinical settings. The primary purpose of this study was to determine if there is an association between dyslipidemia and meibomian gland dysfunction (MGD). The secondary purpose was to identify the factors, if any, that play a role in this association. A case-control study was performed between October 2013 and February 2015 which recruited 109 patients with MGD and 115 control patients without MGD. All participants were of Indian descent and had no history of dyslipidemia. Basic demographic information was collected as well as fasting levels of serum glucose, creatinine, triglycerides, total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL). To calculate differences between groups, Z test or Student t test were used. A stepwise logistic regression model was used to calculate the estimates of odds ratios (ORs), where MGD was the dependent variable, making the independent variables consist of sex, age, body mass index (BMI), triglycerides ≥150 mg/dL, total cholesterol ≥200 mg/dL, LDL ≥130 mg/dL, or HDL ≤40 mg/dL, serum glucose, and serum creatinine. Dyslipidemia, defined by either a fasting total cholesterol level of ≥ 200 mg/dL, triglycerides ≥150 mg/dL, LDL ≥130 mg/dL, or HDL ≤40 mg/dL, was detected in 70 cases (64 %) and 21 controls (18 %), P < 0.001. Mean levels of triglycerides, total cholesterol, LDL, and HDL were 98.5 ± 42.1, 203.1 ± 13.2, 126.1 ± 10.2, and 53.3 ± 4.2 mg/dL, respectively, in cases and 82.3 ± 36.5, 156.6 ± 14.5, 92.2 ± 12.4, 45.8 ± 2.6 mg/dL, respectively, in controls. All differences were statistically significant (P < 0.05). MGD was significantly associated with age >65 years (OR 2.1; 95 % CI 1.2-3.2, P = 0.04), serum triglyceride concentration ≥150 mg/dL (OR 3.2; 95 % CI 1.9-4.4; P = 0.03), total cholesterol ≥200 mg/dL (OR 14.3; 95 % CI 8.2-20.7, P < 0.01), and LDL ≥130 mg/dL (OR 9.1; 95 % CI 6.6-13.2, P < 0.01). Adults from northern rural India with MGD are more likely to have abnormal serum lipid levels compared to age- and sex-matched adults without MGD. Eye care providers may have a role in discovering undiagnosed dyslipidemia, an important risk factor for cardiovascular illness.

The neuromagnetic response to spoken sentences: co-modulation of theta band amplitude and phase.

Speech elicits a phase-locked response in the auditory cortex that is dominated by theta (3-7 Hz) frequencies when observed via magnetoencephalography (MEG). This phase-locked response is potentially explained as new phase-locked activity superimposed on the ongoing theta oscillation or, alternatively, as phase-resetting of the ongoing oscillation. The conventional method used to distinguish between the two hypotheses is the comparison of post- to prestimulus amplitude for the phase-locked frequency across a set of trials. In theory, increased amplitude indicates the presence of additive activity, while unchanged amplitude points to phase-resetting. However, this interpretation may not be valid if the amplitude of ongoing background activity also changes following the stimulus. In this study, we employ a new approach that circumvents this problem. Specifically, we utilize a fine-grained time-frequency analysis of MEG channel data to examine the co-modulation of amplitude change and phase coherence in the post-stimulus theta-band response. If the phase-locked response is attributable solely to phase-resetting of the ongoing theta oscillation, then amplitude and phase coherence should be uncorrelated. In contrast, additive activity should produce a positive correlation. We find significant positive correlation not only during the onset response but also throughout the response period. In fact, transient increases in phase coherence are accompanied by transient increases in amplitude in accordance with a "signal plus background" model of the evoked response. The results support the hypothesis that the theta-band phase-locked response to attended speech observed using MEG is dominated by additive phase-locked activity.

The effect of imaging on the clinical management of breast pain.

BACKGROUND: Breast pain is a common complaint to primary care and breast specialists. Literature recommends imaging to provide reassurance of benign etiology. The effect of imaging on reassurance and subsequent healthcare utilization has not been described. OBJECTIVE: To determine if initial imaging for breast pain reduces subsequent utilization. DESIGN: Retrospective cohort study at a hospital-based breast health practice. PATIENTS: Women referred for breast pain from 2006-2009. MAIN MEASURES: Imaging ordered at initial provider visit; clinical utilization, defined as the number of follow-up visits, diagnostic imaging studies, and biopsies completed within 12 months following initial visit. KEY RESULTS: Sixty-percent of women were age 40 or younger, 87% were from racial/ethnic minority groups. Twenty-five percent had imaging ordered at initial visit. Of those who received initial imaging, 75% had normal radiographic findings, yet 98% returned for additional evaluation. In adjusted analyses, women with initial imaging had increased clinical services utilization (OR 25.4, 95% CI: 16.7, 38.6). Women with normal clinical breast exams who received initial imaging exhibited increased odds for subsequent clinical services utilization (OR 23.8, 95% CI: 12.9, 44.0). Six cancers were diagnosed; imaging in the absence of clinical breast exam abnormalities did not result in any cancer identification. CONCLUSIONS: Initial imaging for women with breast pain increased the odds of subsequent clinical utilization and did not increase reassurance in ruling out malignancy.

The addition of internists to a breast health program.

With the increases in complexity of care for breast health concerns, there is a growing need for efficient and effective clinical evaluation, especially for vulnerable populations at risk for poor outcomes. The Breast Health Center at Boston Medical Center is a multidisciplinary program, with internists providing care alongside breast surgeons, radiologists, and patient navigators. Using a triage system previously shown to have high provider and patient satisfaction, and the ability to provide timely care, patients are assigned to either a breast surgeon or internist. From 2007 to 2009, internists cared for 2,408 women, representing half of all referrals. Women served were diverse in terms of race (33% black, 30% Hispanic, 5% Asian), language (34% require language interpreter), and insurance status (51% had no insurance or public insurance). Most presented with an abnormal screen (breast examination 54% or imaging 4%) while the remainder were seen for symptoms such as pain (26%), non-bloody nipple discharge (4%), or risk assessment (7%). A majority of final diagnoses were made through clinical evaluation alone (n = 1,760, 73%), without the need for additional diagnostic imaging or tissue sampling; 9% (n = 214) received a benign diagnosis with the aid of breast imaging; 19% (n = 463) required tissue sampling. Only 4% went on to see a breast surgeon. Internists diagnosed 15 incident cancers with a median time to diagnosis of 19 days. Patient and provider satisfaction was high. These data suggest that a group of appropriately trained internists can provide quality breast care to a vulnerable population in a multidisciplinary setting. Replication of this model requires the availability of more clinical training programs for non-surgical providers.

So much nuance: A qualitative analysis of parental perspectives on child passenger safety.

OBJECTIVE: To explore barriers and facilitators to optimal child restraint system (CRS) use for diverse parents of newborn infants and to obtain input from parents on the use of technology-assisted remote car seat checks as tools for promoting optimal CRS use. METHODS: Parents were recruited using purposive sampling. Interviews were conducted with English- or Spanish-speaking parents with a full term newborn and regular access to a car. Interviews were conducted by phone, and recorded and transcribed verbatim. Interviews were conducted until thematic saturation was reached. Data were organized for analysis using Atlas.ti, and codes grouped by theme using constant comparison. RESULTS: 30 parents were enrolled. Barriers and facilitators to optimal CRS use were classified into three themes, as were thoughts on the pros and cons regarding remote car seat checks. Themes on barriers and facilitators included motor vehicle and CRS features (such as age and size of the motor vehicle and presence of the Lower Anchors and Tethers for Children LATCH system), resources (availability, accessibility, and accuracy of resources), and parental factors (parental emotions and characteristics). Themes related to pros and cons of remote car seat checks included the ability (and challenge) of remote car seat checks to identify and correct errors, the potential use of remote car seat checks in certain situations (such as CRS transitions and periods of growth), and convenience of remote car seat checks (including increased availability and ease of access). Subthemes with further detail were arranged within each theme identified. CONCLUSION: From a parent perspective, there are several identified barriers and facilitators of optimal CRS use. Although car seat checks were identified as a resource, in-person accessibility was an issue, and there were mixed opinions on technology-assisted remote car seat checks. These results provide a foundation for additional study on targeted interventions, including remote interventions for which there is an increased need due to the COVID-19 pandemic.

Association of Ventilation during Initial Trauma Resuscitation for Traumatic Brain Injury and Post-Traumatic Outcomes: A Systematic Review.

OBJECTIVES: In the absence of evidence of acute cerebral herniation, normal ventilation is recommended for patients with traumatic brain injury (TBI). Despite this recommendation, ventilation strategies vary during the initial management of patients with TBI and may impact outcome. The goal of this systematic review was to define the best evidence-based practice of ventilation management during the initial resuscitation period. METHODS: A literature search of PubMed, CINAHL, and SCOPUS identified studies from 2009 through 2019 addressing the effects of ventilation during the initial post-trauma resuscitation on patient outcomes. RESULTS: The initial search yielded 899 articles, from which 13 were relevant and selected for full-text review. Six of the 13 articles met the inclusion criteria, all of which reported on patients with TBI. Either end-tidal carbon dioxide (ETCO2) or partial pressure carbon dioxide (PCO2) were the independent variables associated with mortality. Decreased rates of mortality were reported in patients with normal PCO2 or ETCO2. CONCLUSIONS: Normoventilation, as measured by ETCO2 or PCO2, is associated with decreased mortality in patients with TBI. Preventing hyperventilation or hypoventilation in patients with TBI during the early resuscitation phase could improve outcome after TBI.

Discrimination of speech stimuli based on neuronal response phase patterns depends on acoustics but not comprehension.

Speech stimuli give rise to neural activity in the listener that can be observed as waveforms using magnetoencephalography. Although waveforms vary greatly from trial to trial due to activity unrelated to the stimulus, it has been demonstrated that spoken sentences can be discriminated based on theta-band (3-7 Hz) phase patterns in single-trial response waveforms. Furthermore, manipulations of the speech signal envelope and fine structure that reduced intelligibility were found to produce correlated reductions in discrimination performance, suggesting a relationship between theta-band phase patterns and speech comprehension. This study investigates the nature of this relationship, hypothesizing that theta-band phase patterns primarily reflect cortical processing of low-frequency (<40 Hz) modulations present in the acoustic signal and required for intelligibility, rather than processing exclusively related to comprehension (e.g., lexical, syntactic, semantic). Using stimuli that are quite similar to normal spoken sentences in terms of low-frequency modulation characteristics but are unintelligible (i.e., their time-inverted counterparts), we find that discrimination performance based on theta-band phase patterns is equal for both types of stimuli. Consistent with earlier findings, we also observe that whereas theta-band phase patterns differ across stimuli, power patterns do not. We use a simulation model of the single-trial response to spoken sentence stimuli to demonstrate that phase-locked responses to low-frequency modulations of the acoustic signal can account not only for the phase but also for the power results. The simulation offers insight into the interpretation of the empirical results with respect to phase-resetting and power-enhancement models of the evoked response.

The Joys and Frustrations of Breastfeeding and Rooming-In Among Mothers With Opioid Use Disorder: A Qualitative Study.

OBJECTIVES: To investigate perspectives of mothers with opioid use disorder regarding breastfeeding and rooming-in during the birth hospitalization and identify facilitators and barriers. METHODS: We conducted in-depth qualitative interviews with 25 mothers with opioid use disorder 1-12 weeks after delivery. Grounded theory analysis was used until thematic saturation was reached. Findings were triangulated, with experts in the field and a subset of informants themselves, to ensure data reliability. RESULTS: Among 25 infant-mother dyads, 36% of infants required pharmacologic treatment, 72% of mothers initiated breastfeeding, and 40% continued until discharge. We identified the following themes: (1) information drives maternal feeding choice; (2) the hospital environment is both a source of support and tension for mothers exerting autonomy in the care of their infants; (3) opioid withdrawal symptoms negatively impact breastfeeding; (4) internal and external stigma negatively impact mothers' self-efficacy; (5) mothers' histories of abuse and trauma affect their feeding choice and bonding; (6) mothers' recovery makes caring for their infants emotionally and logistically challenging; and (7) having an infant is a source of resilience and provides a sense of purpose for mothers on their path of recovery. CONCLUSIONS: Future interventions aimed at increasing breastfeeding and rooming-in during the birth hospitalization should focus on education regarding the benefits of breastfeeding and rooming-in, supporting mothers' autonomy in caring for their infants, minimizing stigma, and maximizing resilience.

Impact of Parental Presence at Infants' Bedside on Neonatal Abstinence Syndrome.

BACKGROUND: Despite increased incidence of neonatal abstinence syndrome (NAS) over the past decade, minimal data exist on benefits of parental presence at the bedside on NAS outcomes. OBJECTIVE: To examine the association between rates of parental presence and NAS outcomes. METHODS: This was a retrospective, single-center cohort study of infants treated pharmacologically for NAS using a rooming-in model of care. Parental presence was documented every 4 hours with nursing cares. We obtained demographic data for mothers and infants and assessed covariates confounding NAS severity and time spent at the bedside. Outcomes included length of stay (LOS) at the hospital, extent of pharmacotherapy, and mean Finnegan withdrawal score. Multiple linear regression modeling assessed the association of parental presence with outcomes. RESULTS: For the 86 mother-infant dyads, the mean parental presence during scoring was on average 54.4% (95% confidence interval [CI], 48.8%-60.7%) of the infant's hospitalization. Maximum (100%) parental presence was associated with a 9 day shorter LOS (r = -0.31; 95% CI, -0.48 to -0.10; P < .01), 8 fewer days of infant opioid therapy (r = -0.34; 95% CI, -0.52 to -0.15; P < .001), and 1 point lower mean Finnegan score (r = -0.35; 95% CI, -0.52 to -0.15; P < .01). After adjusting for breastfeeding, parental presence remained significantly associated with reduced NAS score and opioid treatment days. CONCLUSIONS: More parental time spent at the infant's bedside was associated with decreased NAS severity. This has important implications for clinical practice guidelines for NAS.

Thoracoscopic extracardiac obliteration of the left atrial appendage for stroke risk reduction in atrial fibrillation.

OBJECTIVES: We evaluated left atrial appendage obliteration in high-risk patients with atrial fibrillation (AF). BACKGROUND: Left atrial appendage thrombosis and embolization is the principal mechanism of stroke in AF. Anticoagulation is underutilized and often contraindicated. METHODS: Thoracoscopic Left Appendage, Total Obliteration, No cardiac Invasion (LAPTONI) was undertaken with a loop snare in eight patients and a stapler in seven patients, median age 71 years, with clinical risk factors for stroke and with an absolute contraindication to or failure of prior thrombosis prevention with warfarin. Eleven patients had a history of prior thromboembolism. One patient took sustained warfarin during follow-up. RESULTS: The LAPTONI procedure was completed in 14 of 15 patients, and 1 patient required urgent conversion to open thoracotomy because of bleeding. Patients have been followed up for 8 to 60 months, mean 42 +/- 14 months. One fatal stroke occurred 55 months after surgery, and one non-disabling stroke three months after surgery. Two other deaths occurred, one after coronary bypass surgery and the other from hepatic failure. The subgroup of 11 patients with prior thromboembolism had an annualized rate of stroke of 5.2% per year (95% confidence interval [CI] 1.3 to 21) after LAPTONI, which compares to a rate of 13% per year (95% CI 9.0 to 19) for similar aspirin-treated patients from the Stroke Prevention in Atrial Fibrillation trials (p = 0.15). CONCLUSIONS: The LAPTONI procedure appears technically feasible without immediate disabling neurologic morbidity or mortality, and it demonstrates low post-operative event rates and a statistical trend toward thromboembolic risk reduction in high-risk AF patients.

Relocation consequences on an ophthalmology consultation service from an inpatient to outpatient facility.

IMPORTANCE: This study shows that relocation of an academic ophthalmology residency program from an inpatient to an outpatient setting in western New York does not affect the consult volume but affects management patterns and follow-up rates. OBJECTIVE: To investigate the effects on the ophthalmology consultation service of an academic program with relocation from a Regional Level-1 Trauma center to an outpatient facility. DESIGN: Consultation notes from 3 years before and 3 years after the University at Buffalo's (UB) Department of Ophthalmology relocation from a Regional Level-1 Trauma center (Erie County Medical Center) to an outpatient facility (Ross Eye Institute) were obtained from hospital electronic medical records and analyzed. SETTING: Hospitalized care and institutional practice. PARTICIPANTS: All inpatient or Emergency Room Ophthalmology consultation patients from the Department of Ophthalmology at UB from 2004 to 2010 (1,379 patients). EXPOSURES: None, this was a retrospective chart review. MAIN OUTCOME MEASURES: Patient demographics, reason for consult, diagnoses, and ophthalmic procedures performed by the UB Department of Ophthalmology before and after its relocation. RESULTS: Relocation to the outpatient facility did not affect consult volume (P=0.15). The number of consults focusing on ophthalmic conditions, as a percentage of the yearly total, rose 460% (P=0.0001), while systemic condition consults with ocular manifestations fell 83% (P=0.0001). Consults for ocular trauma decreased 65% (P=0.0034). Consults ending with a diagnosis of "normal exam" fell, as a percentage of the yearly total (56%, P=0.0023), while diagnoses of new ocular conditions rose 17% (P=0.00065). The percentage of consults for Medicaid patients fell 12% (P=0.0001), while those for privately insured patients rose 15% (P=0.0001). The number of ophthalmic procedures did not change, but postconsult patient follow-up fell from 23% at the Erie County Medical Center clinic to 2% after the move to Ross Eye Institute, a ≥97% decrease. CONCLUSION AND RELEVANCE: Relocation of UB's academic Ophthalmology program from an inpatient department to an outpatient facility had no effect on its consultation patient or procedure volume, but it significantly affected the nature of consult diagnoses and decreased outpatient follow-up by >90% at the latter location. Many hospitals are creating separate outpatient facilities that may experience similar obstacles.

Extensive coronary dissection treated with endarterectomy and coronary reconstruction.

Acute coronary dissection is an uncommon event, usually not related to typical coronary risk factors, usually in women, and usually diagnosed at autopsy. This report describes a young woman with extensive left anterior descending coronary artery (LAD) dissection, refused for intervention since there was no lesion to angioplasty and no artery to bypass. A long arteriotomy was made, removing under direct vision all of the torn and dissected tissue, just as would be done for extensive LAD endarterectomy. A vein was split and attached to reconstruct the artery. Normal left ventricular function was restored.

Is attrition of advanced trauma life support acquired skills affected by trauma patient volume?

BACKGROUND: We assessed the effect of trauma volume on skills attrition among physicians completing the advance trauma life support (ATLS) course. METHODS: Cognitive (40 item multiple choice question [MCQ] examination) and clinical (4 objective structured clinical examinations [OSCE] trauma stations) performances were compared among physicians who completed the ATLS course, subdividing them into groups treating more than 50 and fewer than 50 trauma patients per year. Both groups had 12 physicians from six periods (n = 144) related to time of course completion: immediate (0), 6 months, 2 years, 4 years, 6 years, and 8 years after ATLS. OSCE scores (maximum standardized: 20), the degree of adherence to priorities (priority score: range 1 to 7), the degree of organized approach (approach score: range from 1 to 5) were compared. RESULTS: The mean precourse MCQ scores (59.4% to 62.4%) were similar for both groups. Immediate and progressive cognitive skill attrition and detailed clinical skill attrition were worse in the low volume group. Global skills (organized approach and adherence to priorities) were preserved similarly for at least 8 years in all groups. CONCLUSIONS: Our data suggest that trauma volume affects trauma skills attrition.
