Analysis of physician recipients of recognition awards from the American Academy of Physical Medicine and Rehabilitation by Race and Ethnicity.

BACKGROUND: Medical society recognition awards are important resources for physicians in advancing their careers. There is a need to better understand the representation of physician recipients by race and ethnicity, especially in women with intersectional identities. OBJECTIVE: To assess the proportions of American Academy of Physical Medicine and Rehabilitation (AAPM&R) award recipients by race and ethnicity and the intersection of gender. DESIGN: Cross-sectional and retrospective study. SETTING AND METHODS: One hundred seven (n = 107) published online physician award recipients from 2011 to 2020 were categorized by race, ethnicity, and gender by two independent researchers. There was 100% interrater agreement on race and gender and 95% on ethnicity. Data were analyzed with descriptive analysis and multilinear regression. MAIN OUTCOME MEASUREMENTS: Awards given to physicians coded by race (White/Caucasian, Asian, and Black/African American), ethnicity (Hispanic/Latino), and the intersection of gender with race and ethnicity were analyzed. The primary comparator was proportions by race, ethnicity, and gender of academic physicians in physical medicine and rehabilitation (PM&R) using Association of American Medical Colleges (AAMC) data. A secondary aim was recipients' proportions compared to AAMC benchmarks for all practicing physiatrists. RESULTS: There were no significant differences in representation of award recipients by race or ethnicity compared to the primary comparator of their percentages in academic PM&R. Notably, 96.3% of awards were given to physicians identified as being in or having been in academic medicine. Secondary analysis of award recipients to all practicing physiatrists revealed significant underrepresentation of recipients who were coded as (1) White/Caucasian women, Asian men and women, Black/African American men and women (p = .016), and (2) Hispanic/Latino men and women (p = .028). CONCLUSIONS: This is a novel study assessing race and ethnicity in physician recognition awards presented by a medical society. No significant disparities were found among recipients as compared to representation in academic PM&R. However, there were significant disparities when compared to all practicing physiatrists. These findings deserve further investigation and consideration as medical societies strive to equitably support all members.

An Analysis of Scalp Thickness and Other Novel Risk Factors for Deep Brain Stimulator Infections.

INTRODUCTION:  Deep brain stimulator (DBS) infections are a persistent problem for patients undergoing this procedure. They may require further surgery, treatment with antibiotics, or even removal of the device. To date, no consensus exists on the best practices to avoid DBS infections or what factors predispose patients to an eventual infection. The goal of this study was to examine several patient factors for association with DBS infection. METHODS:  A single-center, single-surgeon quality improvement database was queried. All patients who experienced an infection were identified. The primary variable analyzed was scalp thickness. Other pre-specified, secondary variables included routine intraoperative cultures, operative time, diagnosis, and age. RESULTS:  None of the independent variables examined were significantly associated with DBS infections. Only two of the 46 infections qualified as surgical site infections as defined by the Centers for Disease Control. CONCLUSION:  DBS infections are independent of all of the predictor variables analyzed. Surgical site infections, according to traditional definitions, are not the optimal definition for evaluating DBS infections/erosions. New studies must examine new variables that are not routinely gathered in this population. Also, because of the rare event rates and difficulty in randomizing patients to exposures, a large, multicenter registry may be the optimal study design to solve this clinical problem.

Eye tracking detects disconjugate eye movements associated with structural traumatic brain injury and concussion.

Disconjugate eye movements have been associated with traumatic brain injury since ancient times. Ocular motility dysfunction may be present in up to 90% of patients with concussion or blast injury. We developed an algorithm for eye tracking in which the Cartesian coordinates of the right and left pupils are tracked over 200 sec and compared to each other as a subject watches a short film clip moving inside an aperture on a computer screen. We prospectively eye tracked 64 normal healthy noninjured control subjects and compared findings to 75 trauma subjects with either a positive head computed tomography (CT) scan (n=13), negative head CT (n=39), or nonhead injury (n=23) to determine whether eye tracking would reveal the disconjugate gaze associated with both structural brain injury and concussion. Tracking metrics were then correlated to the clinical concussion measure Sport Concussion Assessment Tool 3 (SCAT3) in trauma patients. Five out of five measures of horizontal disconjugacy were increased in positive and negative head CT patients relative to noninjured control subjects. Only one of five vertical disconjugacy measures was significantly increased in brain-injured patients relative to controls. Linear regression analysis of all 75 trauma patients demonstrated that three metrics for horizontal disconjugacy negatively correlated with SCAT3 symptom severity score and positively correlated with total Standardized Assessment of Concussion score. Abnormal eye-tracking metrics improved over time toward baseline in brain-injured subjects observed in follow-up. Eye tracking may help quantify the severity of ocular motility disruption associated with concussion and structural brain injury.

Detection of third and sixth cranial nerve palsies with a novel method for eye tracking while watching a short film clip.

OBJECT: Automated eye movement tracking may provide clues to nervous system function at many levels. Spatial calibration of the eye tracking device requires the subject to have relatively intact ocular motility that implies function of cranial nerves (CNs) III (oculomotor), IV (trochlear), and VI (abducent) and their associated nuclei, along with the multiple regions of the brain imparting cognition and volition. The authors have developed a technique for eye tracking that uses temporal rather than spatial calibration, enabling detection of impaired ability to move the pupil relative to normal (neurologically healthy) control volunteers. This work was performed to demonstrate that this technique may detect CN palsies related to brain compression and to provide insight into how the technique may be of value for evaluating neuropathological conditions associated with CN palsy, such as hydrocephalus or acute mass effect. METHODS: The authors recorded subjects' eye movements by using an Eyelink 1000 eye tracker sampling at 500 Hz over 200 seconds while the subject viewed a music video playing inside an aperture on a computer monitor. The aperture moved in a rectangular pattern over a fixed time period. This technique was used to assess ocular motility in 157 neurologically healthy control subjects and 12 patients with either clinical CN III or VI palsy confirmed by neuro-ophthalmological examination, or surgically treatable pathological conditions potentially impacting these nerves. The authors compared the ratio of vertical to horizontal eye movement (height/width defined as aspect ratio) in normal and test subjects. RESULTS: In 157 normal controls, the aspect ratio (height/width) for the left eye had a mean value ± SD of 1.0117 ± 0.0706. For the right eye, the aspect ratio had a mean of 1.0077 ± 0.0679 in these 157 subjects. There was no difference between sexes or ages. A patient with known CN VI palsy had a significantly increased aspect ratio (1.39), whereas 2 patients with known CN III palsy had significantly decreased ratios of 0.19 and 0.06, respectively. Three patients with surgically treatable pathological conditions impacting CN VI, such as infratentorial mass effect or hydrocephalus, had significantly increased ratios (1.84, 1.44, and 1.34, respectively) relative to normal controls, and 6 patients with supratentorial mass effect had significantly decreased ratios (0.27, 0.53, 0.62, 0.45, 0.49, and 0.41, respectively). These alterations in eye tracking all reverted to normal ranges after surgical treatment of underlying pathological conditions in these 9 neurosurgical cases. CONCLUSIONS: This proof of concept series of cases suggests that the use of eye tracking to detect CN palsy while the patient watches television or its equivalent represents a new capacity for this technology. It may provide a new tool for the assessment of multiple CNS functions that can potentially be useful in the assessment of awake patients with elevated intracranial pressure from hydrocephalus or trauma.
