Despite urinary tract infections (UTIs) being a common problem in patients with spinal cord injuries (SCIs), and a well-known complication of invasive urologic procedures, little consensus exists regarding the standard of care for peri-procedural antibiotic use for SCI patients undergoing urodynamics studies (UDS). Our research seeks to evaluate local antibiotic prophylaxis pattern in SCI patients undergoing UDS, assess incidence of post-procedural UTI, describe local antibiotic resistance trends, and provide antibiotic stewardship considerations to guide future practice. Retrospective cohort study of SCI patients undergoing UDS from January 2010 to January 2020 at a Veterans Affairs SCI Center. Data on patient demographics, UTI risk factors, pre-procedural urinalysis and culture, and peri-procedural antibiotics was extracted. Incidence of post-procedural UTI was tabulated. Findings were summarized using descriptive statistics. 331 patients were studied. Pre-procedural urine culture was done in 73% of cases, with positive results in 49%. E. coli was the most commonly isolated organism (19%). Antibiotics were used in 86% of cases, 26% of which had a negative culture. A onetime dose of intramuscular gentamicin given immediately pre-procedure was the most common practice (53%; N = 152). No cases of post-procedural UTIs were identified during the study period. No post-UDS UTIs occurred under current local practice where most patients received a one-time dose of intramuscular gentamicin as prophylaxis. Though routine gentamicin prophylaxis may play a role in reducing UTI incidence, the low rate of post-UDS UTI in this population, including patients with positive cultures who received no antibiotics, suggests the possibility of refining practice patterns to improve antibiotic stewardship.

Background: Comorbidity indices have been used to represent the overall medical complexity of patient populations in clinical research; however, it is not known how well they capture the comorbidities of patients with a stroke or brain injury admitted to inpatient rehabilitation facilities (IRFs).Objective: To determine how well commonly used comorbidity indices capture the comorbidities of patients admitted to IRFs after a stroke or brain injury.Design: Cross‐sectional, retrospective study.Setting: IRFs nationwide.Participants: Adults from four impairment groups: (1) hemorrhagic stroke, (2) ischemic stroke, (3) nontraumatic brain injury (NTBI), and (4) traumatic brain injury (TBI).Main Outcome Measures: International Classification of Diseases, Tenth Revision, Clinical Modification (ICD‐10‐CM) codes were extracted from the Uniform Data System for Medical Rehabilitation (UDSMR) for IRF discharges from October 1, 2015 to December 31, 2017. The percentage of discharges captured by Deyo‐Charlson, Elixhauser, and Centers for Medicare and Medicaid Services (CMS) tiers was determined, as was the percentage of comorbidities captured. These measures were also compared with respect to their ability to capture chronic medical complexity by examining the percentage of codes captured after removal of codes deemed to represent hospital complications or sequela of the admission diagnosis.Results: The percentage of discharges without at least one ICD‐10‐CM code captured by any index ranged from 0.3%‐3.8%. The percentage of comorbidities with a prevalence exceeding 1% captured by at least one index ranged from 37.1%‐43.6%. Chronic comorbidities were most likely to be captured by Elixhauser (40.7%‐44.4%), followed by Deyo‐Charlson (7.8%‐9.6%), then CMS tiers (4.5%‐6.9%). Existing comorbidity measures capture most IRF discharges related to a brain injury or stroke, whereas most medical comorbidities escape representation. Several common, functionally relevant diagnoses were not captured.Conclusion: The use of comorbidity indices in the IRF neurologic injury population should account for the fact that these measures miss several common, important comorbidities.

Objective: To review the literature regarding outcomes of surgical and nonsurgical management of lower extremity (LE) fractures in chronic spinal cord injury (SCI).Type: Systematic review.Literature Survey: Medline (PubMed), Embase, Cochrane Database of Systemic Reviews, Cochrane Central, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, International Clinical Trials Registry Platform, and International Standard Randomized Controlled Trials were searched from January 1, 1966, to March 1, 2019.Methodology: Search was restricted to English language and adults (age ≥ 18 yr). Titles and abstracts were reviewed for relevance to study topics for inclusion. Case reports, reviews, non‐SCI population studies, and studies examining fractures at the time of acute SCI were excluded. References of included articles from the original search and task force and external submissions yielded two additional articles that were included in the review after voting by task force members. Data extraction was performed by four task force members using a data extraction form, glossary, and instructions created in Microsoft Excel. Quality assessment was performed by three methodologists using prespecified criteria.Synthesis: Twenty‐three articles were included. Use of surgery to treat LE fractures in chronic SCI has increased, though nonoperative management was still more frequently reported. Regardless of type of management, amputations, nonunion/malunion, and pressure injuries were among the most commonly reported complications. Functional and quality of life outcomes were less frequently reported.Conclusions: There is insufficient evidence to support operative versus nonoperative management as best practice for management of LE fracture of SCI. Existing literature was limited by small sample sizes, lack of randomization or matched study designs, significant heterogeneity in populations and treatment strategies studied, and variability in defining and reporting outcomes of interest. The field would benefit from future research to address study design issues and standardization of outcome reporting to facilitate comparison of outcomes of operative versus nonoperative management.

Objective: Youth with attention deficit hyperactivity disorder (ADHD) perform more poorly on preseason cognitive testing and report more baseline concussion-like symptoms but prior studies have not examined the influence of medication use on test performance or symptom reporting. This study investigated whether medication use is relevant when interpreting baseline ImPACT® results from student athletes with ADHD. Method: Participants were 39,247 adolescent athletes, ages 13–18 (mean age = 15.5 years, SD = 1.3), who completed baseline cognitive testing with ImPACT®. The sample included slightly more boys (54.4%) than girls. Differences in ImPACT® composite scores and concussion-like symptom reporting (between ADHD/No medication, ADHD/Medication, No ADHD/Medication, and Control groups) were examined with ANOVAs, conducted separately by gender. Results: In this large, state-wide data-set, youth with ADHD had greater rates of invalid ImPACT results compared to control subjects (ADHD/No Medication: girls = 10.9%, boys = 10%; ADHD/Medication: girls = 8.1%, boys = 9.1%; Controls: girls = 5.2%, boys = 6.7%). Groups differed across all ImPACT® composites (invalid profiles were removed), in the following order (from worse to better performance): ADHD/No Medication, ADHD/Medication, and Control participants. Pairwise effect sizes indicated that the largest differences were on the Visual Motor Speed composite, with the ADHD/No medication group performing worse than the ADHD/Medication group and the Controls. The ADHD/Medication group did not differ meaningfully from Controls on any composite, for either sex (d = 0 to .19). The ADHD groups did not differ on total symptom scores but both ADHD groups endorsed significantly more symptoms compared to Controls. Conclusions: Contrary to our hypothesis, we found medication use had only a subtle effect on cognitive performance and no significant effect on concussion-like symptom reporting. Student athletes reporting medication use for ADHD performed comparably to student athletes with no ADHD on baseline testing.
