Improved Medical Student Engagement with EHR Documentation following the 2018 Centers for Medicare and Medicaid Billing Changes.

BACKGROUND: Medical student note writing is an important part of the training process but has suffered in the electronic health record (EHR) era as a result of student notes being excluded from the billable encounter. The 2018 CMS billing changes allow for medical student notes to be used for billable services provided that physical presence requirements are met, and attending physicians satisfy performance requirements and verify documentation. This has the potential to improve medical student engagement and decrease physician documentation burden. METHODS: Our institution implemented medical student notes as part of the billable encounter in August 2018 with support of our compliance department. Note characteristics including number, type, length, and time in note were analyzed before and after implementation. Rotating medical students were surveyed regarding their experience following implementation. RESULTS: There was a statistically significant increase in the number of student-authored notes following implementation. Attending physicians' interactions with student notes greatly increased following the change (4% of student notes reviewed vs. 84% of student notes). Surveyed students reported that having their notes as part of the billable record made their notes more meaningful and enhanced their learning. The majority of surveyed students also agreed that they received more feedback following the change. CONCLUSION: Medical students are interested in writing notes for education and feedback. Inclusion of their notes as part of the billable record can facilitate their learning and increase their participation in the note writing process.

Children with epilepsy demonstrate macro- and microstructural changes in the thalamus, putamen, and amygdala.

PURPOSE: Despite evidence for macrostructural alteration in epilepsy patients later in life, little is known about the underlying pathological or compensatory mechanisms at younger ages causing these alterations. The aim of this work was to investigate the impact of pediatric epilepsy on the central nervous system, including gray matter volume, cerebral blood flow, and water diffusion, compared with neurologically normal children. METHODS: Inter-ictal magnetic resonance imaging data was obtained from 30 children with epilepsy ages 1-16 (73% F, 27% M). An atlas-based approach was used to determine values for volume, cerebral blood flow, and apparent diffusion coefficient in the cerebral cortex, hippocampus, thalamus, caudate, putamen, globus pallidus, amygdala, and nucleus accumbens. These values were then compared with previously published values from 100 neurologically normal children using a MANCOVA analysis. RESULTS: Most brain volumes of children with epilepsy followed a pattern similar to typically developing children, except for significantly larger putamen and amygdala. Cerebral blood flow was also comparable between the groups, except for the putamen, which demonstrated decreased blood flow in children with epilepsy. Diffusion (apparent diffusion coefficient) showed a trend towards higher values in children with epilepsy, with significantly elevated diffusion within the thalamus in children with epilepsy compared with neurologically normal children. CONCLUSION: Children with epilepsy show statistically significant differences in volume, diffusion, and cerebral blood flow within their thalamus, putamen, and amygdala, suggesting that epilepsy is associated with structural changes of the central nervous system influencing brain development and potentially leading to poorer neurocognitive outcomes.

Utility of prenatal MRI in the evaluation and management of fetal ventriculomegaly.

OBJECTIVE: Fetal ventriculomegaly may occur in isolation or as part of a broader syndrome. We aimed to determine the added value of magnetic resonance imaging (MRI) for informing the pre-natal and postnatal care of pregnancies complicated by ventriculomegaly (VM). STUDY DESIGN: Retrospective analysis of all cases of prenatally diagnosed VM referred to the fetal center at Lucile Packard Children's Hospital Stanford 1/1/2009-6/1/2014 were reviewed. Ultrasound (US) and MRI findings were reviewed, and the added yield of MRI evaluated. RESULTS: A total of 91 cases of fetal VM were identified and 74 (81%) underwent MRI. In 62/74 (84%) cases, additional CNS or non-CNS findings, not seen on US, were discovered on MRI, of which 58 were CNS-related. Forty-six (62%) of the additional findings were considered clinically relevant, of which 45 were CNS-related. CONCLUSION: Fetal MRI identifies additional, clinically relevant CNS and non-CNS findings in a majority of cases of VM following initial US.

In-depth investigations of adolescents and adults with holoprosencephaly identify unique characteristics.

PurposeWith improved medical care, some individuals with holoprosencephaly (HPE) are surviving into adulthood. We investigated the clinical manifestations of adolescents and adults with HPE and explored the underlying molecular causes.MethodsParticipants included 20 subjects 15 years of age and older. Clinical assessments included dysmorphology exams, cognitive testing, swallowing studies, ophthalmic examination, and brain magnetic resonance imaging. Genetic testing included chromosomal microarray, Sanger sequencing for SHH, ZIC2, SIX3, and TGIF, and whole-exome sequencing (WES) of 10 trios.ResultsSemilobar HPE was the most common subtype of HPE, seen in 50% of the participants. Neurodevelopmental disabilities were found to correlate with HPE subtype. Factors associated with long-term survival included HPE subtype not alobar, female gender, and nontypical facial features. Four participants had de novo pathogenic variants in ZIC2. WES analysis of 11 participants did not reveal plausible candidate genes, suggesting complex inheritance in these cases. Indeed, in two probands there was a history of uncontrolled maternal type 1 diabetes.ConclusionIndividuals with various HPE subtypes can survive into adulthood and the neurodevelopmental outcomes are variable. Based on the facial characteristics and molecular evaluations, we suggest that classic genetic causes of HPE may play a smaller role in this cohort.

Special requirements for electronic medical records in neurology.

Electronic medical records (EMRs) are being rapidly adapted in the United States with goals of improving patient care, increasing efficiency, and reducing costs. Neurologists must become knowledgeable about the utility and effectiveness of the important parts of these systems specifically needed for care of neurology patients. The field of neurology encompasses complex disorders whose diagnosis and management heavily relies on detailed medical documentation of history and physical examination, and often on specialty-specific ancillary tests and extensive neuroimaging. Small discrepancies in documentation or absence of an in-hand ancillary test result can drastically change the current workup or treatment decision of a complex patient with neurologic disease. We describe current models and opportunities for improvements to EMRs that provide utility and efficiency in the care of neurology patients.

The impact of an online social network with wireless monitoring devices on physical activity and weight loss.

BACKGROUND: Online social networks (OSNs) are a new, promising approach for catalyzing health-related behavior change. To date, the empirical evidence on their impact has been limited. PURPOSE: Using a randomized trial, we assessed the impact of a health-oriented OSN with accelerometer and scales on participant's physical activity, weight, and clinical indicators. METHODS: A sample of 349 PeaceHealth Oregon employees and family members were randomized to the iWell OSN or a control group and followed for 6 months in 2010-2011. The iWell OSN enabled participants to connect with "friends," make public postings, view contacts' postings, set goals, download the number of their steps from an accelerometer and their weight from a scale, view trends in physical activity and weight, and compete against others in physical activity. Both control and intervention participants received traditional education material on diet and physical activity. Laboratory data on weight and clinical indicators (triglycerides, high-density lipoprotein, or low-density lipoprotein), and self-reported data on physical activity, were collected at baseline, 3 months, and 6 months. RESULTS: At 6 months, the intervention group increased leisure walking minutes by 164% compared with 47% in the control group. The intervention group also lost more weight than the controls (5.2 pounds compared with 1.5 pounds). There were no observed significant differences in vigorous exercise or clinical indicators between the 2 groups. Among intervention participants, greater OSN use, as measured by number of private messages sent, was associated with a greater increase in leisure walking and greater weight reduction over the study period. CONCLUSIONS: The study provides evidence that interventions using OSNs can successfully promote increases in physical activity and weight loss.

Stimulus-induced drop episodes in Coffin-Lowry syndrome.

The Coffin-Lowry syndrome (CLS) is a rare but well-defined X-linked semidominant syndrome characterized by psychomotor and growth retardation, and progressive skeletal changes. CLS is caused by loss of function mutations in the Rps6ka3 gene encoding the ribosomal S6 kinase 2 (RSK2) protein. A distinctive paroxysmal disorder has been described in some CLS patients, characterized by episodes of sudden falling, without apparent alteration of consciousness, usually induced by unexpected tactile or auditory stimuli. Duration of episodes is very short, usually lasting a few seconds. The appellation "Stimulus-induced drop episodes" (SIDEs) was proposed for these non-epileptic events in CLS patients. SIDEs are clinically heterogeneous; with some patients exhibiting cataplexy-like events characterized by sudden hypotonia and collapse, and others hyperekplexia-like episodes with a startle response. The pathophysiology of SIDEs is not well understood.

Newborn with prenatally diagnosed choroidal fissure cyst and panhypopituitarism and review of the literature.

Little has been reported on fetal diagnosis of choroidal fissure cysts and prediction of the clinical complications that can result. We describe the case of a near-term male infant with prenatally diagnosed choroidal fissure cyst and bilateral clubfeet. His prolonged course in the neonatal intensive care nursery was marked by severe panhypopituitarism, late-onset diabetes insipidus, placement of a cystoperitoneal shunt, and episodes of sepsis. Postnatal genetic evaluation also revealed an interstitial deletion involving most of band 10q26.12 and the proximal half of band 10q26.13. The patient had multiple readmissions for medical and surgical indications and died at 6 months of age. This case represents the severe end of the spectrum of medical complications for children with choroidal fissure cysts. It highlights not only the importance of comprehensive evaluation and multidisciplinary management and counseling in such cases, but also the need for heightened vigilance in these patients.

Decrease in hospital-wide mortality rate after implementation of a commercially sold computerized physician order entry system.

BACKGROUND: Implementations of computerized physician order entry (CPOE) systems have previously been associated with either an increase or no change in hospital-wide mortality rates of inpatients. Despite widespread enthusiasm for CPOE as a tool to help transform quality and patient safety, no published studies to date have associated CPOE implementation with significant reductions in hospital-wide mortality rates. OBJECTIVE: The objective of this study was to determine the effect on the hospital-wide mortality rate after implementation of CPOE at an academic children's hospital. PATIENTS AND METHODS: We performed a cohort study with historical controls at a 303-bed, freestanding, quaternary care academic children's hospital. All nonobstetric inpatients admitted between January 1, 2001, and April 30, 2009, were included. A total of 80,063 patient discharges were evaluated before the intervention (before November 1, 2007), and 17,432 patient discharges were evaluated after the intervention (on or after November 1, 2007). On November 4, 2007, the hospital implemented locally modified functionality within a commercially sold electronic medical record to support CPOE and electronic nursing documentation. RESULTS: After CPOE implementation, the mean monthly adjusted mortality rate decreased by 20% (1.008-0.716 deaths per 100 discharges per month unadjusted [95% confidence interval: 0.8%-40%]; P = .03). With observed versus expected mortality-rate estimates, these data suggest that our CPOE implementation could have resulted in 36 fewer deaths over the 18-month postimplementation time frame. CONCLUSION: Implementation of a locally modified, commercially sold CPOE system was associated with a statistically significant reduction in the hospital-wide mortality rate at a quaternary care academic children's hospital.

Neuroimaging advances in holoprosencephaly: Refining the spectrum of the midline malformation.

Holoprosencephaly (HPE) is a complex congenital brain malformation characterized by failure of the forebrain to bifurcate into two hemispheres, a process normally completed by the fifth week of gestation. Modern high-resolution brain magnetic resonance imaging (MRI) has allowed detailed analysis of the cortical, white matter, and deep gray structural anomalies in HPE in living humans. This has led to better classification of types of HPE, identification of newer subtypes, and understanding of the pathogenesis. Currently, there are four generally accepted subtypes of HPE: alobar, semilobar, lobar, and middle interhemispheric variant. These subtypes are defined primarily by the degree and region of neocortical nonseparation. Rather than there being four discrete subtypes of HPE, we believe that there is a continuum of midline neocortical nonseparation resulting in a spectrum disorder. Many patients with HPE fall within the border zone between the neighboring subtypes. In addition, there are patients with very mild HPE, where the nonseparation is restricted to the preoptic (suprachiasmic) area. In addition to the neocortex, other midline structures such as the thalami, hypothalamic nuclei, and basal ganglia are often nonseparated in HPE. The cortical and subcortical involvements in HPE are thought to occur due to a disruption in the ventral patterning process during development. The severity of the abnormalities in these structures determines the severity of the neurodevelopmental outcome and associated sequelae.

Compound heterozygosity for mutations in PAX6 in a patient with complex brain anomaly, neonatal diabetes mellitus, and microophthalmia.

We report on a patient with trisomy 21, microophthalmia, neonatal diabetes mellitus, hypopituitarism, and a complex structural brain anomaly who was a member of a large bilineal family with eye anomalies. The patient inherited a different mutation in PAX6 from each parent and is the only known living and second reported patient with compound heterozygosity for mutations in PAX6. PAX6 is a transcription factor involved in eye and brain development and has roles in pancreatic and pituitary development. Clinical evaluation of the propositus and his parents demonstrated the effects of mutations of differing severity in multiple individuals.

Differential diagnosis and evaluation in pediatric multiple sclerosis.

The differential diagnosis for multiple sclerosis (MS) in childhood and adolescence includes infectious, inflammatory, and neoplastic disorders as well as metabolic neurogenetic leukodystrophies, toxic leukodystrophies, and vascular conditions. The evaluation is determined by the clinical and neuroradiologic presentation. A minimal diagnostic battery is proposed. More expanded evaluations are indicated for specific or atypical clinical presentations.

Acute disseminated encephalomyelitis.

Acute disseminated encephalomyelitis (ADEM) is an immune-mediated inflammatory disorder of the CNS characterized by a widespread demyelination that predominantly involves the white matter of the brain and spinal cord. The condition is usually precipitated by a viral infection or vaccination. The presenting features include an acute encephalopathy with multifocal neurologic signs and deficits. Children are preferentially affected. In the absence of specific biologic markers, the diagnosis of ADEM is still based on the clinical and radiologic features. Although ADEM usually has a monophasic course, recurrent or multiphasic forms have been reported, raising diagnostic difficulties in distinguishing these cases from multiple sclerosis (MS). The International Pediatric MS Study Group proposes uniform definitions for ADEM and its variants. We discuss some of the difficulties in the interpretation of available literature due to the different terms and definitions used. In addition, this review summarizes current knowledge of the main aspects of ADEM, including its clinical and radiologic diagnostic features, epidemiology, pathogenesis, and outcome. An overview of ADEM treatment in children is provided. Finally, the controversies surrounding pediatric MS and ADEM are addressed.

Links between abnormal brain structure and cognition in holoprosencephaly.

Converging information on medical issues, motor ability, and cognitive outcomes is essential when addressing long-term clinical management in children with holoprosencephaly. This study considered whether adding more informative structural indices to classic holoprosencephaly categories would increase prediction of cognitive outcomes. Forty-two children with holoprosencephaly were examined to determine the association of deep gray nuclei abnormalities with cognitive abilities and the effect of motor skill deficits on cognitive performance. Additionally, a cognitive profile was described using the Carter Neurocognitive Assessment, an experimental diagnostic instrument designed specifically for young children with severe neurodevelopmental dysfunction. Findings indicated that nonseparation of the deep gray nuclei was significantly associated with the cognitive construct of vocal communication, but not with the cognitive constructs of social awareness, visual attention, or auditory comprehension. Importantly, motor skill deficits did not significantly affect performance on the Carter Neurocognitive Assessment. This study is the first investigation to provide a descriptive overview of specific cognitive skills in this group of children. The results also strongly suggest that this feature of the brain's structure does not predict all aspects of neurodevelopmental function. These findings contribute a critical component to the growing body of knowledge regarding the medical and clinical outcomes of children with holoprosencephaly.

Factor analysis of neuroanatomical and clinical characteristics of holoprosencephaly.

The objective of this study is to better understand the relationship between neuroradiologic and clinical characteristics in holoprosencephaly (HPE) using the multivariate analysis called factor analysis. HPE is a brain malformation characterized by incomplete cleavage of the cerebral hemispheres and deep gray structures. We performed evaluations on 89 children with HPE that included their history, developmental assessment, and physical examination. Ten clinical variables included in factor analysis were the grade of spasticity, dystonia, choreoathetosis, hypotonia, mobility, upper extremity/hand function, expressive language, feeding/swallowing difficulty, endocrinopathies, and temperature dysregulation. Five neuroimaging variables graded by pediatric neuroradiologists were the grade of HPE (from least to most severe: lobar, semilobar, and alobar) and the degree of non-separation of caudate, lentiform, thalamic, and hypothalamic nuclei. Factor analysis using principle component extraction and varimax rotation was utilized. Four significant factors were identified: (1) neuroimaging/developmental factor, (2) motor factor, (3) hypothalamic/oromotor factor, and (4) hypotonia factor. These four factors accounted for 65.2% of the variance. In this factor analysis of HPE patients, we were able to reduce the large number of clinical and radiological variables into four factors. These factors and the constructs underlying them provide structure to the data and provide key parameters for future studies involving neurodevelopmental outcomes in HPE.

Endocrine disorders associated with holoprosencephaly.

OBJECTIVE: To investigate the incidence of endocrinopathies in holoprosencephaly (HPE) and correlate the severity of the endocrinopathies with the neuroanatomic abnormalities. STUDY DESIGN: We reviewed the histories and medical records of 117 children with HPE for endocrinopathies and related treatments. Neuroimaging studies were graded for severity of HPE, hypothalamus non-separation, and pituitary abnormalities. RESULTS: Diabetes insipidus (DI) occurred in 70% of patients with classic HPE. The severity of the DI correlated with the grade of HPE and hypothalamic non-separation (p < 0.0001). Anterior pituitary dysfunctions were much less common. Hypothyroidism was identified in 11% of patients, hypocorticism in 7%, and growth hormone deficiency in 5%. Only one patient with middle interhemispheric variant of holoprosencephaly (MIH) had any of these disorders. CONCLUSIONS: Patients with HPE have a high incidence of DI that may be related to the failure of cleavage of hypothalamic nuclei. Anterior pituitary dysfunctions are much less common than DI.

Evaluation and management of children with holoprosencephaly.

Recent advances in genetics and neuroimaging have greatly contributed to our understanding of the spectrum of midline brain and craniofacial malformations known as holoprosencephaly. Neuroradiologic studies have provided detailed characteristics of four major types of holoprosencephaly: alobar, semilobar, lobar, and middle interhemispheric variant. Clinical studies in children with these types of holoprosencephaly have revealed a wide range of survival and neurologic outcomes. Motor and developmental dysfunctions correlate with the severity of the brain malformation in holoprosencephaly. These findings have implications in the management of medical problems associated with holoprosencephaly and overall prognostication.

Mild developmental delay in terminal chromosome 6p deletion.

Deletions involving the short arm of chromosome 6 are relatively rare. Although features of this condition are variable, common findings include developmental delay, ocular abnormalities, hearing loss, and cardiac defects. In an effort to define further the clinical variability of this condition, we report a 6-year-old female with a de novo terminal deletion of chromosome 6 at band 6p24, with mild gross motor delays and normal cognition.

Microangiopathy of brain, retina, and inner ear (Susac's syndrome) in an adolescent female presenting as acute disseminated encephalomyelitis.

Susac's syndrome is a rare disorder that consists of microangiopathy of the brain, retina, and inner ear and usually affects young women in young adulthood. The triad of clinical manifestations consists of acute encephalopathy with neurologic signs, branch retinal artery occlusion (BRAO), and sensorineural hearing loss. We present a case of an adolescent female who presented at age 16 years with clinical and neuroimaging features of acute disseminated encephalomyelitis (ADEM). The full triad did not develop until 2.5 years after the initial neurologic presentation.
