ABSTRACT
OBJECTIVE: The Veterans Health Administration (VHA), the largest single provider of spinal cord injury and disorder (SCI/D) care in the United States, currently mandates that every patient receives a screening urine culture during the annual evaluation, a yearly comprehensive history and physical examination. This testing has shown in a small subset of patients to overidentify asymptomatic bacteriuria that is then inappropriately treated with antibiotics. The objective of the current analysis was to assess the association of the annual evaluation on urine testing and antibiotic treatment in a national sample of Veterans with SCI/D. DESIGN/METHOD: A retrospective cohort study using national VHA electronic health record data of Veterans with SCI/D seen between October 1, 2017-September 30, 2019 for their annual evaluation. RESULTS: There were 9447 Veterans with SCI/D who received an annual evaluation; 5088 (54%) had a urine culture obtained. 2910 cultures (57%) were positive; E. coli was the most common organism obtained (12.9% of total urine cultures). Of the patients with positive urine cultures, 386 were prescribed antibiotics within the 7 days after that encounter (13%); of the patients with negative cultures (n = 2178), 121 (6%) were prescribed antibiotics; thus, a positive urine culture was a significant driver of antibiotic use (p < 0.001). CONCLUSION: The urine cultures ordered at the annual exam are often followed by antibiotics; this practice may be an important target for antibiotic stewardship programs in SCI.

Few studies have harnessed social media to explore patients' experiences with urinary tract infection (UTI); therefore, we captured UTI experiences and future research suggestions through a Twitter-disseminated survey. The survey posed three qualitative questions inquiring about the impact of UTIs, greatest UTI management hurdle, and research suggestions. We also asked participants to rate how seriously others perceive UTIs and the importance of UTIs in their life (scale: 1-100 (highest)). The study period spanned from January to June 2021. Coding was performed in duplicate, followed by thematic analysis. Of 466 participants from 22 countries, 128 considered their UTIs recurrent (n = 43) or chronic (n = 85). Six major themes emerged: UTIs drastically impact (1) physical and (2) mental health and (3) cause severe limitations in life activities. Patients reported (4) negative clinician interactions and perceived inadequate care, (5) a lack of knowledge and awareness surrounding UTIs, and (6) research gaps in UTI diagnostics and treatment. The participants considered UTIs extremely important (median: 100, IQR: 90-100), but characterized others' perceptions of them as less serious (median: 20, IQR: 10-30). Our survey revealed a patient population struggling with UTIs, particularly chronic UTIs. Our findings highlight perceived shortcomings in current UTI treatment and diagnostics.
ABSTRACT
Background: The SARS-CoV-2 (COVID-19) pandemic brought the public overwhelming and conflicting information. Rates of trust in healthcare professionals have been declining among laypersons over the past five decades. In this setting, we sought to evaluate the use of medications, both with or without a prescription, to prevent and treat SARS-CoV-2 as well as trust in healthcare among patients in a primary care clinic. Design: We surveyed 150 veterans in primary care clinic waiting rooms at a large southwestern tertiary care Veterans Affairs hospital. This survey was performed in March-November 2021. Methods: The survey asked about respondents' demographics, use of medications, nutritional supplements, and other remedies for the prevention and treatment of COVID-19, perceived access to care using Agency for Healthcare Research and Quality (AHRQ) Consumer Assessment of Healthcare Providers and System (CAHPS), overall health status, and barriers to medical appointments in the last 12 months. Distrust was measured using the Revised Health Care Distrust scale. We used univariate and multivariate linear regression analyses to study predictors of distrust to healthcare. Results: Forty-two (28%) of 150 respondents reported taking an agent for the prevention of COVID-19, while 4% reported storing antibiotics for the treatment of COVID-19, if diagnosed. Medications were obtained from medical providers, US stores or markets, the Internet, home stockpiles, and other countries. Medications with potentially harmful effects taken for the prevention and treatment of COVID-19 included hydroxychloroquine, pseudoephedrine, and antibiotics. Among those surveyed, the mean (SD) on the health system distrust score was 2.2 (0.6) on a scale of 1-5, with 5 indicating higher distrust. Younger age, self-reported poor health, lack of a regular physician, and self-reported poor access to care were independently associated with distrust in healthcare. Conclusion: Self-medication to prevent COVID-19 infection with unproven therapies was common among respondents, as was some level of distrust in the healthcare system. Access to care was one of the modifiable factors associated with distrust. Future studies may explore whether improving trust may moderate self-treatment behavior and storage of potentially harmful medications. Plain Language Summary: Self-Medication Habits and Trust in Healthcare Among Patients in a Primary Care Setting in the United States The public has received information from many different sources on COVID-19. Trust in healthcare leadership has also been impacted. We studied self-medication habits to prevent or treat COVID-19 among a group of primary care patients in a large hospital system in the Southwest United States. We also explored these patients' trust in their healthcare system.We asked people waiting in primary care clinic waiting rooms whether they had taken any medications, nutritional supplements, or other remedies to prevent or treat COVID-19. We also asked people whether they stored medications in the event that they were diagnosed with COVID. The survey explored patients' trust in the healthcare system through a validated trust survey tool. The survey also assessed basic demographic information, health literacy, access to care, and self-reported health status. These survey answers were analyzed to see whether there was an association between trust in healthcare and other factors including self-medication habits, access to care, demographics, or perceived health.This study found that over 25% of the 150 people surveyed had taken a medication, nutritional supplement, or remedy in an attempt to prevent COVID. We found that some people were taking potentially harmful medications, including hydroxychloroquine, pseudoephedrine, and antibiotics. We found that patients' distrust score was 2.2 on a scale of 1-5 (5 is associated with higher distrust). Self-medication for the prevention or treatment of COVID was not associated with distrust; however, younger age, self-perceived lack of access to healthcare, self-perceived poor overall health, and not having a regular doctor were predictors for lower trust. This information provides a basis to further study self-medication habits as well as ways to improve trust in the healthcare system.
ABSTRACT
STUDY DESIGN: Retrospective cohort. OBJECTIVES: The primary outcome of the study was to identify patient characteristics associated with a positive COVID-19 test. The secondary outcome was to identify patient characteristics associated with mortality from COVID-19. SETTING: Veterans Health Administration (VHA) National Spinal Cord Injury and Disorders (SCI) Registry, created by the National Spinal Cord Injury and Disorders SCI Program Office in March 2020. METHODS: Data was analyzed in the form of descriptive statistics and then subsequent regression analysis was performed. RESULTS: A total of 4,562 persons with SCI were tested for COVID-19 between March and July 2020, and 290 were positive. The study found that African Americans had increased odds of testing positive for COVID-19 (OR 1.53 (1.18-2.00), p < 0.01). Increased age correlated with increased odds of mortality after testing positive for COVID-19 (1.046 (1.003-1.090)). Non-smokers had lower odds of mortality following positive COVID-19 test (0.15 (0.04-0.52)). No association was found between neurologic level of injury (NLI) and positive COVID-19 test or increased mortality. Increased Body Mass Index (BMI) did correlate with positive COVID-19 test but not increased mortality. The case fatality rate for persons with SCI and a positive test for COVID-19 was 12%. CONCLUSIONS: It is important to define the risk factors for patients with SCI to elucidate and mitigate individual and population risks. These risk factors also can play a role in determining the allocation of critical healthcare resources.

ABSTRACT
High rates of antimicrobial resistance and formation of biofilms makes treatment of Escherichia coli catheter-associated urinary tract infections (CAUTI) particularly challenging. CAUTI affect 1 million patients per year in the United States and are associated with morbidity and mortality, particularly as an etiology for sepsis. Phage have been proposed as a potential therapeutic option. Here, we report the development of phage cocktails that lyse contemporary E. coli strains isolated from the urine of patients with spinal cord injury (SCI) and display strong biofilm-forming properties. We characterized E. coli phage against biofilms in two in vitro CAUTI models. Biofilm viability was measured by an MTT assay that determines cell metabolic activity and by quantification of colony forming units. Nine phage decreased cell viability by >80% when added individually to biofilms of two E. coli strains in human urine. A phage cocktail comprising six phage lyses 82% of the strains in our E. coli library and is highly effective against young and old biofilms and against biofilms on silicon catheter materials. Using antibiotics together with our phage cocktail prevented or decreased emergence of E. coli resistant to phage in human urine. We created an anti-biofilm phage cocktail with broad host range against E. coli strains isolated from urine. These phage cocktails may have therapeutic potential against CAUTI.
ABSTRACT
BACKGROUND: Chart reviews often fall short of determining what drove antibiotic treatment of asymptomatic bacteriuria (ASB). To overcome this shortcoming, we searched providers' free-text for documentation of their decision-making and for misleading signs and symptoms that may trigger unnecessary treatment of ASB. METHODS: We reviewed a random sample of 10 positive urine cultures per month, per facility, from patients in acute or long-term care wards at 8 Veterans Affairs facilities. Cultures were classified as urinary tract infection (UTI) or ASB, and as treated or untreated. Charts were searched for 13 potentially misleading symptoms, and free-text documentation of providers' decision-making was classified into 5 categories. We used generalized estimating equations logistic regression to identify factors associated with ASB treatment. RESULTS: One hundred fifty-eight (27.5%) of 575 ASB cases were inappropriately treated with antibiotics. Significant factors associated with inappropriate treatment included: abdominal pain, falls, decreased urine output, urine characteristics, abnormal vital signs, laboratory values, and voiding issues. Providers prescribed an average of 1.4 antimicrobials to patients with ASB, with cephalosporins (41%) and fluoroquinolones (21%) being the most common classes prescribed. CONCLUSIONS: Chart reviews of providers' decision-making highlighted new factors associated with inappropriate ASB treatment. These findings can help design antibiotic stewardship interventions for ASB.
ABSTRACT
BACKGROUND: As more left ventricular-assist devices (LVADs) are implanted, multidrug-resistant LVAD infections are becoming increasingly common, partly due to bacterial biofilm production. To aid in developing bacteriophage therapy for LVAD infections, we have identified the most common bacterial pathogens that cause LVAD driveline infections (DLIs) in our heart transplant referral center. MATERIALS AND METHODS: We studied a retrospective cohort of patients who received LVADs from November 2003 to August 2017 to identify the common causative organisms of LVAD infection. We also studied a prospective cohort of patients diagnosed with DLIs from October 2018 to May 2019 to collect bacterial strains from DLIs for developing bacteriophages to lyse causative pathogens. LVAD infections were classified as DLI, bacteremia, and pump/device infections in the retrospective cohort. RESULTS: In the retrospective cohort of 582 patients, 186 (32.0%) developed an LVAD infection, with 372 microbial isolates identified. In the prospective cohort, 96 bacterial strains were isolated from 54 DLIs. The microorganisms causing DLIs were similar in the two cohorts; the most common isolate was Staphylococcus aureus. We identified 6 prospective S. aureus strains capable of biofilm formation. We developed 3 bacteriophages that were able to lyse 5 of 6 of the biofilm-forming S. aureus strains. CONCLUSIONS: Similar pathogens caused LVAD DLIs in our retrospective and prospective cohorts, indicating our bacterial strain bank will be representative of future DLIs. Our banked bacterial strains will be useful in developing phage cocktails that can lyse ≥80% of the bacteria causing LVAD infections at our institution.

INTRODUCTION: Antimicrobial-resistant bacterial infections are an increasing public health threat and people with spinal cord injury (SCI) are disproportionally at higher risk. National guidelines concerning urine testing after SCI are conflicting. Unnecessary urine testing in the SCI population (with high asymptomatic bacteriuria prevalence) leads to unnecessary antimicrobial use, propagating resistant infections, especially urinary tract infections (UTIs). OBJECTIVES: (a) Describe UTI antimicrobial adherence in patients with SCI. (b) Explore SCI patient knowledge and attitudes toward current urine testing and treatment practices. DESIGN: Mixed methods. SETTING: Veterans Health Administration (VHA) patients with SCI. PARTICIPANTS: Veterans identified as having SCI seen at a VHA facility nationwide. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Self-reported medication adherence, patient beliefs and behaviors toward UTIs and antimicrobial use. RESULTS: A total of 105 Morisky Medication Adherence Scale-8 (MMAS-8) surveys were completed out of 369 distributed surveys (28% response rate). Overall, patients reported high medication adherence (mean score of 7.2/8, with 8 being a perfect adherence score). Ten qualitative interviews were completed. Themes identified include generally high adherence to prescribed antimicrobial courses and high levels of patient satisfaction with current outpatient VHA SCI bladder care. The quantitative findings converge with these themes observed in the qualitative interviews; patients were satisfied with current urine testing and treatment practices. CONCLUSIONS: Veterans with SCI are generally satisfied with their current UTI management and self-report taking antimicrobials for UTIs as prescribed. Veterans with SCI typically report high trust in their SCI providers and value their advice on bladder care management. Therefore, it is imperative for clinicians to provide evidence-based education to patients, as well as ensure that each prescribed course of antibiotics for UTI is clinically necessary. Information from this study will guide an intervention promoting appropriate urine testing and antimicrobial prescription practices by SCI providers.
