INTRODUCTION Unlike dementia, the effect of mild cognitive impairment (MCI) on outcomes after deep brain stimulation (DBS) in Parkinson's disease (PD) is less clear. We aimed to examine the effect of MCI on short- and long-term DBS outcomes. METHODS To study the effect of MCI type, cognitive domains (attention, language, visuospatial, memory, executive(More)
BACKGROUND Patients with epilepsy or multiple sclerosis (MS) have high risks of depression and increased risks of suicide, but little is known about their risks of suicidal ideation. OBJECTIVE We sought to (1) estimate the prevalence of thoughts of being better off dead or of self-harm among patients with epilepsy or MS, (2) identify risk factors for such(More)
BACKGROUND Recently, van Walraven developed a weighted summary score (VW) based on the 30 comorbidities from the Elixhauser comorbidity system. One of the 30 comorbidities, cardiac arrhythmia, is currently excluded as a comorbidity indicator in administrative datasets such as the Nationwide Inpatient Sample (NIS), prompting us to examine the validity of the(More)
BACKGROUND CONTEXT Anterior cervical discectomy and fusion (ACDF) and posterior cervical foraminotomy (PCF) are both used to surgically treat patients with cervical radiculopathy and have been shown to have similar outcomes. Nonetheless, ACDF has become increasingly more commonplace compared with PCF, in part because of a pervasive belief that PCF has a(More)
BACKGROUND CONTEXT Atlantoaxial fusion is used to correct atlantoaxial instability that is often secondary to traumatic fractures, Down syndrome, or rheumatoid arthritis. The effect of age and comorbidities on outcomes following atlantoaxial fusion is unknown. PURPOSE This study aimed to better understand trends and predictors of outcomes and charges(More)
OBJECTIVES To investigate the association between socioeconomic status and deep brain stimulation (DBS) outcomes in Parkinson's disease (PD). MATERIALS AND METHODS We analyzed a cohort of PD patients who underwent DBS from 2007 to 2011, who had Clinical Global Impression Scale-Improvement subscale (CGI-I) scores at approximately one year postsurgery. We(More)
OBJECTIVE The current study retrospectively evaluated patient reported outcomes (PROs) collected before and after at least 2 sessions of onabotulinumtoxinA (onabot) injections for chronic migraine. Depression was assessed by the Patient Health Questionnaire-9. METHOD Chronic migraineurs receiving onabot were identified. In addition to the Patient Health(More)
OBJECTIVE The Accreditation Council for Graduate Medical Education (ACGME) established duty-hour regulations for accredited residency programs on July 1, 2003. It is unclear what changes occurred in the national incidence of medication errors in surgical patients before and after ACGME regulations. DESIGN Patient and hospital characteristics for pre- and(More)
BACKGROUND A majority of stroke patients suffer from obstructive sleep apnea (OSA), which can go unrecognized as the current OSA screens do not perform well in stroke patients. The objective of this study is to modify the existing OSA screening tools for use in stroke patients. METHODS The cohort study consisted of patients who completed the validated OSA(More)
Electronic health records (EHRs) present an opportunity to access large stores of data for research, but mapping raw EHR data to clinical phenotypes is complex. We propose adding patient-reported data to the EHR to improve phenotyping performance and describe a retrospective cohort study demonstrating a test case in depressive disorder. We compared four(More)
