ABSTRACT

Background: Convenience clinics-such as urgent care centers (UCCs), retail clinics, and freestanding emergency departments (FSEDs)-where patients can receive treatment for a variety of medical conditions have increased in number and popularity. We quantify the impact an FSED had on UCC visits in an underserved area in North Baton Rouge, Louisiana. Methods: All FSED and UCC visits were abstracted from 2015 to 2020. Visits were classified using International Classification of Diseases, Tenth Revision codes. We used a time series analysis to evaluate the association of nonemergent and emergent visits to the UCC after the opening of the FSED. Visits were also aggregated at the census block group (neighborhood) level. Demographic characteristics and the neighborhood Area Deprivation Index were used to compare UCC utilization before and after the FSED opened and to describe the visits to the UCC and the FSED. Results: We found a difference in the demographic composition of patients presenting to the UCC after the FSED opened. Emergent visits decreased at the UCC, but nonemergent visits did not change after the FSED opened. The majority of visits to the FSED were nonemergent, and the proportion of nonemergent visits to the FSED increased during the hours that the UCC was closed. The majority of visits to the FSED came from neighborhoods with a high Area Deprivation Index. Conclusion: The opening of an FSED resulted in a reduction of emergent visits to the UCC without impacting the number of nonemergent visits. The opening of an FSED in a poor, healthcare-resource-scarce area resulted in significantly more patients from deprived neighborhoods being treated at the FSED and UCC.

ABSTRACT

Background: Both psychiatric disorders and diverse medications used to treat them have been associated with alopecia. The objective of our study was to investigate the existence of an association between attention-deficit/hyperactivity disorder (ADHD) stimulant medication (ASM) and various types of alopecia. Methods: We conducted a retrospective case-control medical record review of patients between the ages of 6 and 18 years seen in dermatology clinics during a 10-year period. Cases included patients diagnosed with alopecia areata (AA), alopecia totalis (AT), or alopecia universalis (AU). We matched 3 controls on age and sex to each case. We reviewed patients' medical records for the following medications: lisdexamfetamine, amphetamine/dextroamphetamine, dexmethylphenidate, and methylphenidate. We examined the association between medications used to treat ADHD and diagnoses of AA, AT, and/or AU by calculating a series of odds ratios and 95% CIs. Results: We identified 124 cases (110 with AA, 11 with AT, and 3 with AU) and 372 controls. We found a strong association between AU and ASM use (P<0.0071). No relationship between ASM use and other types of hair loss was found. Conclusion: Although the sample size of cases with AU was small, we found a significant association between AU and ASM. While further study is needed, practitioners may consider close monitoring of patients with AA who use ASM for the development of worsening disease and discontinue the medication if the patient experiences an increase in hair loss that appears to be progressing to AU.

ABSTRACT

BACKGROUND: Despite the trend of rising Emergency Department (ED) visits over the past decade, researchers have observed drastic declines in number of ED visits due to the COVID-19 pandemic. The purpose of the current study was to examine the impact of the COVID-19 pandemic and governor mandated Stay at Home Order on ED super utilizers. METHODS: This was a retrospective chart review of patients presenting to the 12 emergency departments of the Franciscan Mission of Our Lady Hospital System in Louisiana between January 1, 2018 and December 31, 2020. Patients who were 18 years of age or older and had four ED visits within a one-year period (2018, 2019, or 2020) were classified as super-utilizers. We examined number and category of visits for the baseline period (January 2018 - March 2020), the governor's Stay at Home Order, and the subsequent Reopening Phases through December 31, 2020. RESULTS: The number of visits by super utilizers decreased by over 16% when the Stay at Home Order was issued. The average number of visits per week rose from 1010.63 during the Stay at Home Order to 1198.09 after the Stay at Home Order was lifted, but they did not return to Pre-COVID levels of approximately 1400 visits per week in 2018 and 2019. When categories of visits were examined, this trend was found for emergent visits (p < 0.001) and visits related to injuries (p < 0.001). Non-emergent visits declined during the Stay at Home Order compared to the baseline period (p < 0.001), and did not increase significantly during reopening compared to the Stay at Home Order (p = 0.87). There were no changes in number of visits for psychiatric purposes, alcohol use, or drug use during the pandemic. CONCLUSIONS: Significant declines in emergent visits raise concerns that individuals who needed ED treatment did not seek it due to COVID-19. However, the finding that super utilizers with non-emergent visits continued to visit the ED less after the Stay at Home Order was lifted raises questions for future research that may inform policy and interventions for inappropriate ED use.

ABSTRACT

OBJECTIVE: We describe the effect of simulation-based education on residents' adherence to protocols for and performance of central venous access. METHODS: Internal medicine and emergency medicine residents underwent a central venous access course that included a lecture, video presentation, readings, and simulation demonstrations presented by faculty. Baseline data were collected before the course was initiated. After a skills session where they rehearsed their ultrasound-guided central venous access skills, residents were evaluated using a procedural checklist and written knowledge exam. Residents also completed questionnaires regarding confidence in performing ultrasound-guided central venous access and opinions about the training course. RESULTS: Residents demonstrated significant improvement on the written knowledge exam (P < 0.0001) and Standard Protocol Checklist (P < 0.0001) after the training course. Training improved a number of patient safety elements, including adherence to sterile technique, transparent dressing, discarding sharps, and ordering postprocedure x-rays. However, a number of residents failed to wash their hands, prepare with chlorhexidine, drape the patient using a sterile technique, anesthetize the site, and perform a preprocedure time-out. Significant improvement in procedural skills was also noted for reduction in skin-to-vein time (P < 0.003) as well as a reduction in number of residents who punctured the carotid artery (P < 0.02). CONCLUSIONS: Simulation-based education significantly improved residents' knowledge and procedural skills along with their confidence. Adherence to the protocol also improved. This study illustrates that simulation-based education can improve patient safety through training and protocols.

ABSTRACT

BACKGROUND: The objective of the current study was to determine whether emergency medicine residents' United States Medical Licensing Examination (USMLE) scores are significantly associated with first-attempt passage of the American Board of Emergency Medicine (ABEM) qualifying (written) examination. We hypothesized that USMLE Step 2 Clinical Knowledge (CK) scores would be useful in predicting students who passed the ABEM qualifying examination on their first attempt. METHODS: For this retrospective cohort study, we examined the data of residents who successfully completed training at two emergency medicine residency programs between the years 2002-2013. Because scores on the USMLE Step examinations varied greatly across years, we obtained means and standard deviations from the National Board of Medical Examiners. We subtracted the mean score for the year each resident took the examination from the resident's examination score, creating centered Step 1 and centered Step 2 CK scores. RESULTS: A multivariate logistic regression analysis indicated that centered Step 2 CK scores could be used to predict the odds of passing the ABEM qualifying examination (odds ratio = 1.05 [95% confidence interval 1.02 to 1.08, P < 0.001]). Using a Step 2 CK score cutoff of 7 points lower than the mean yielded 64% sensitivity and 81% specificity for predicting passage of the ABEM written examination on the first attempt. CONCLUSION: Program directors and selection committees may wish to consider whether applicants' Step 2 CK scores are near the national average when making ranking decisions, as this variable is highly predictive of passing the ABEM qualifying examination on the initial attempt.

ABSTRACT

BACKGROUND: Obtaining central venous cannulation of the internal jugular vein is an important skill for physicians to master. To our knowledge, no studies to date have examined residents' preferences or the safety of the oblique approach compared to other approaches. This study compared medical residents' preferences for and performance of ultrasound-guided central venous access using the transverse, longitudinal, and oblique approaches. METHODS: Emergency medicine and internal medicine residents (n = 72) at an urban community hospital participated in a central venous access course. To assess the residents' preferences, residents were asked to rank the transverse, longitudinal, and oblique approaches as first, second, or third. In addition to preference, skin-to-vein time, carotid artery puncture, and successful completion on the first attempt during a final skills analysis were measured. RESULTS: During the final skills analysis, the majority (87.5%) of residents preferred the transverse approach. The oblique approach had a significantly larger proportion of failures of technique than the transverse approach (P = 0.02). No significant differences in successful cannulation on the first attempt, skin-to-vein time, or carotid artery puncture among the 3 approaches were found during the final skills assessment. CONCLUSION: The majority of residents preferred the transverse approach to the longitudinal and oblique approaches. Although no significant differences among the 3 approaches were found in performance measures, more failures of technique occurred with the oblique approach. This study suggests that novices may require in-depth training and supervision to become proficient with the oblique approach.

ABSTRACT

Neurocognitive screeners are used to detect symptoms of HIV-Associated Neurocognitive Disorders (HAND). However, the degree to which education and socioeconomic status affect these screeners remains unclear. Neurocognitive screeners were administered to 187 socioeconomically disadvantaged HIV+ individuals upon entering treatment who had no other risk factors for HAND. The false positive rates were: 84% for the Montreal Cognitive Assessment, 59% for the International HIV Dementia Scale, and 28.3% for the Modified HIV Dementia Scale. Given these high false positive rates, the screeners may be more useful for establishing baseline functioning and sequential testing to detect deterioration.

ABSTRACT

BACKGROUND: Many users believe that synthetic cannabinoids offer a safe and legal means of getting high. However, spikes in emergency department visits have been associated with use of synthetic cannabinoids. The purpose of the current study was to document emergency department visits from three large hospitals in one metropolitan area over a two month period. METHOD: This was a retrospective chart review examining 218 patients presenting to three inner city emergency departments between March and April 2014. Data collected included demographic information, information regarding ED diagnosis and treatment, signs and symptoms, ancillary testing, ED disposition, and cost of the medical treatment. RESULTS: The majority of patients (75.7%) were discharged after ED workup, but 12.4% were admitted for medical treatment and 11.5% were admitted for psychiatric treatment. Ten patients (4.6%) were admitted to the ICU. Symptoms experienced most frequently include: hypertension, tachycardia, agitation, drowsiness, nausea, and confusion. Cluster analysis revealed four symptom clusters of individuals presenting after using synthetic cannabinoids: 1) confusion, hostility, agitation, 2) nausea, vomiting, abdominal pain, 3) drowsiness, and 4) the absence of these symptoms. CONCLUSION: This study has three important findings. First, significant ED resources are being used to treat individuals presenting due to effects of synthetic cannabis. Second, synthetic cannabis is not a benign substance. Third, while the hostile and agitated user is generally presented in the media, this study finds significant heterogeneity in presentation. Further research is needed to fully understand the implications of synthetic cannabinoid use.

ABSTRACT

OBJECTIVE: Schizophrenia spectrum disorders (SSDs), are diagnosed more frequently among African-Americans (AAs) than Caucasians. It has been suggested that cultural differences in symptom presentation and endorsement (including reporting spiritual/religious experiences) may influence this disparity. The current study investigated the relationship between endorsement of spiritual auditory and visual hallucinations and subsequent diagnosis of SSD among AA patients. DESIGN: Participants (N = 471 AAs) completed the Mini International Neuropsychiatric Interview-Plus (MINI-Plus) Screening Interview as part of their intake to a HIV outpatient clinic. Endorsement of auditory or visual (A/V) hallucinations was explored with the MINI-Plus Psychotic Disorder Module and questions regarding the content of the unusual experience. RESULTS: Logistic regression indicated that endorsement of A/V hallucinations significantly predicted a SSD (OR = 41.6, 95% CI 13.7-126.0, p < .001). However, when hallucinations were spiritual in nature, odds of an SSD fell dramatically (OR = 0.22, 95% CI 0.07-0.64, p < .001). CONCLUSIONS: The current study indicates that not all visual and auditory hallucinations are symptomatic of a psychotic disorder in AA patients. Many of these experiences may be related to spirituality. Clinicians assessing AA patients need to query content of, meaning attributed to, and distress associated with A/V unusual experiences.

ABSTRACT

BACKGROUND: This study sought to examine the epidemiology and mortality of violent suicide attempts presenting to trauma centers and to describe differences in male and female suicide attempters presenting to trauma centers by decade of age. METHOD: Data from the National Trauma Data Bank (American College of Surgeons) years 2010-2012 were used for this study. E-codes indicative of self-inflicted injury (e950-e959) were used to identify violent suicide attempts. Incidents were categorized by decade of age at admission. We examined the effects of age and sex on rates of violent suicide attempts, mechanism used, and mortality. RESULTS: In all, 36035 violent suicide attempts were identified in the National Trauma Data Bank. Proportion of in-hospital mortality differed significantly with age (P< .001). Individuals aged 20 to 29 years had a significantly higher number of attempts with 15.6% mortality, whereas individuals aged 80 plus year had fewer attempts but with 45.9% mortality. There were significant interactions between sex and age on lethality of suicide attempts (P< .01) and mechanism chosen (P< .01), with men being more likely to use firearms across age groups. CONCLUSION: This study highlights the importance of examining the epidemiology of suicide attempts across sex and age. There are significant differences in rate of attempts, lethality of mechanism, and in-hospital mortality. Future studies should continue to investigate violent suicide attempts to design and implement effective treatment strategies targeted toward specific populations.

ABSTRACT

Engagement in treatment for a person having a behavioral health crisis is critical to fully address the concerns of the individual as well as to prevent future crises. This study explored the benefits of establishing outreach visits from a local community mental health provider to psychiatric patients in an emergency department. Using retrospective analysis of data collected by a local mental health agency, the effect of receiving face to face contact in the emergency room with a community mental health worker (and/or telephone follow up) was compared to no outreach interaction. The effect of this intervention was a significant increase in initial appointment attendance at the local mental health clinic in the aftermath of a psychiatric crisis. Community mental health services provided in partnership with community emergency departments may improve patient engagement in aftercare and consequently help alleviate future behavioral health crises as well as return visits to the emergency department.

ABSTRACT

STUDY OBJECTIVE: The current study examines patients' comprehension of their emergency department (ED) encounter, using physician observers to document both physician communication and details of the encounter. METHODS: Eighty-nine patients were recruited from a convenience sample in an urban ED. To be included in this study, patients had to have low triage levels (4 and 5) and be discharged from the ED. Physician observers were present throughout the encounter, documenting physician communication and procedures performed. Patients were then interviewed by physician observers about their communication with physicians, accuracy in recalling facts about the encounter, and understanding of information provided during the encounter. RESULTS: The majority of patients were black and had a high school education. Physicians typically engaged in behaviors related to building rapport and diagnosing patients. However, physicians informed patients about test results and diagnoses less frequently. In terms of patients' accuracy and understanding of the visit, patients were generally aware of basic facts in regard to their ED encounter (ie, whether they had blood drawn), but 65.9% of patients demonstrated less than "good" understanding in at least 1 area assessed. CONCLUSION: The findings of the current study indicate physicians could improve communication with patients, particularly in regard to care received in the ED. This study also indicates that a large percentage of patients fail to understand information about their ED encounter even when physicians provide it. A primary limitation of the current study is the relatively homogenous physician sample.

ABSTRACT

Advances in mobile phone technology now provide a myriad of resources to physicians' fingertips. However, the medical profession continues to struggle with potential for misuse of these devices. There is a need for better understanding of physicians' uses of smartphones in order to establish guidelines for appropriate and professional behavior. The purpose of the current study was to survey physicians' and medical students' practices concerning smartphone use in the healthcare setting. Physicians and medical students were asked to complete anonymous surveys regarding uses of smartphones within the past month in various healthcare settings. Overall, the participants reported distinctly different patterns in the uses they made of their phones in different settings (P<.001), with most individuals engaging in most behaviors while on break but few using their smartphones while with patients or during procedures. It appears that physicians and medical students make decisions about using their smartphones according to some combination of three considerations: degree of relevance to patient care, the appropriateness of the behavior in front of patients, and the issue of how disruptive that behavior may be.

ABSTRACT

We report the case of an adolescent girl who was 14 years old at initial presentation. A shy, immature and timid individual, she began to have recurring, progressive episodes characterised by insomnia, paranoia, distorted thinking and mood instability with a mix of depressive and manic-like symptoms. An extensive medical work up was unrevealing. Her family noted a pattern that coincided with her menstrual cycle. An endocrine consult was obtained, and the diagnosis of catamenial psychosis was performed. After treatment with leuprolide, resulting in a shutdown of the hypothalamic-pituitary-ovarian axis, the patient's symptoms were resolved completely.

ABSTRACT

OBJECTIVE: The purpose of this study was to determine if patients with nontraumatic causes of elevated intracranial pressure (ICP) could be identified by ultrasound measurement of optic nerve sheath diameter (ONSD). It was hypothesized that an ONSD greater than or equal to 5 mm would identify patients with elevated ICP. METHOD: This was a prospective observational trial comparing ONSD with ICP measured by opening pressure manometry on lumbar puncture (LP). The cohort consisted of a convenience sample of adult patients presenting to the emergency department, requiring LP. The ONSD measurement was performed before computed tomography and LP. The physician performing the LP was blinded to the result of the ONSD measurement. An opening pressure on manometry of greater than or equal to 20 cm H2O and an ONSD greater than or equal to 5 mm were considered elevated. RESULTS: Fifty-one patients were included in our study, 24 (47%) with ICP greater than or equal to 20 cm H2O and 27 (53%) with ICP less than 20 cm H2O. The sensitivity of ONSD greater than or equal to 5 for identifying elevated ICP was 75% (95% confidence interval, 53%-90%) with specificity of 44% (25%-65%). The area under the receiver operator characteristic curve was 0.69 (0.54-0.84), suggesting a relationship between ONSD and ICP. CONCLUSION: An ONSD greater than or equal to 5 mm was associated with elevated ICP in nontraumatic causes of elevated ICP. Although a relationship exists, a sensitivity of 75% does not make ONSD measurement an adequate screening examination for elevated ICP in this patient population.

ABSTRACT

Previously developed validity measures are largely lacking in their ability to accurately distinguish malingerers from individuals with genuine intellectual disabilities (ID). The purpose of the present study was to develop a validity index for the Stanford-Binet Intelligence Scales-Fifth Edition (SB-5) aimed at detecting malingered ID. Fifty-four college students were instructed to feign impairment consistent with mental retardation while completing the SB-5. Simulated malingerers performed significantly poorer on the Block Span task of the SB-5 than did individuals with genuine impairment. A Block Span Validity Index (BSVI) cutoff score of less than 10 showed perfect specificity by correctly identifying all persons with true ID and demonstrated 52% sensitivity in identifying persons feigning impairment. For the detection of malingered ID, the BSVI yielded favorable results, although more research is needed to validate the BSVI using a known-groups study design.

ABSTRACT

Delusional parasitosis (DP) is a rare form of somatic delusions where a person believes that he or she is infected with worms, bugs, or other parasites. In the literature, DP has been discussed as a presenting feature of cortical dementias but has not been documented as a presenting feature in subcortical dementias such as HIV-associated dementia. We present a case of a 56-year-old male referred from the dermatology clinic for neuropsychological assessment after presenting with persisting claims that he was infected with "bugs" despite evidence to the contrary. The patient had a history of HIV and substance abuse. The patient was diagnosed with dementia due to HIV disease and psychosis due to dementia (i.e., DP) based on the neuropsychological evaluation. This case report suggests that neuropsychological evaluations may be indicated for patients presenting with DP and risk factors for either cortical or subcortical dementias such as HIV-associated dementia.

ABSTRACT

Tests of word-reading ability, such as the North American Adult Reading Test (NAART) and Wide Range Achievement Test (WRAT) Word Reading subtest, are often used by neuropsychologists to estimate premorbid intelligence. However, despite the fundamental basis in reading, little work has been done to calculate or estimate literacy level from NAART performance. Additionally, few prior studies have evaluated the use of word-reading tests in underrepresented populations such as African Americans or individuals with lower socioeconomic status and educational attainment. Finally, while the correlations between the NAART and older editions of the WRAT are known, no study has yet examined the relationship between the NAART and WRAT-Fourth Edition (WRAT-4). The purpose of the current study, then, was to replicate and extend prior research in these areas. NAART and WRAT-4 Word Reading (WRAT4WR) performances were examined in a sample of 173 primarily African American individuals who were HIV-positive and who had an average of fewer than 12 years of education. Analyses revealed a strong correlation between NAART error scores and WRAT4WR raw scores (r = -.866, p < .001). Linear regression was used to establish the predictive equation to estimate WRAT4WR scores from NAART errors. This information allows for determining reading grade-level equivalents based on NAART error scores.

ABSTRACT

Current research suggests that effort indices designed for the detection of malingered neurocognitive functioning do not have adequate sensitivity or specificity for use in cases where malingered mental retardation (MR) is the issue. Therefore, development and validation of reliable, objective measures for the detection of malingered MR have become imperative for both forensic and disability cases in recent years. The purpose of this study was to develop and validate an embedded malingering index for the Stanford Binet Intelligence Scales, Fifth Edition. Data from individuals in the SB5 standardization sample, who had intellectual deficits in the MR range, were used. Items that were rarely missed by the MR sample were pooled and validated using a sample of 54 college students asked to feign MR. Nonverbal items that were missed significantly more frequently by the malingering "analog MR sample" were retained and composed the Stanford Binet Rarely Missed Items-Nonverbal (SBRMI-NV) index. When only individuals who successfully malingered MR (FSIQ < 71) were included, sensitivity of 0.88 and specificity of 1.00 were obtained. Results indicate that although the SBRMI-NV needs further validation, it shows great promise in the detection of malingered MR.
