RESUMEN
BACKGROUND: Persistent mortality in adults hospitalized due to acute COVID-19 justifies pursuit of disease mechanisms and potential therapies. The aim was to evaluate which virus and host response factors were associated with mortality risk among participants in Therapeutics for Inpatients with COVID-19 (TICO/ACTIV-3) trials. METHODS: A secondary analysis of 2625 adults hospitalized for acute SARS-CoV-2 infection randomized to 1 of 5 antiviral products or matched placebo in 114 centers on 4 continents. Uniform, site-level collection of participant baseline clinical variables was performed. Research laboratories assayed baseline upper respiratory swabs for SARS-CoV-2 viral RNA and plasma for anti-SARS-CoV-2 antibodies, SARS-CoV-2 nucleocapsid antigen (viral Ag), and interleukin-6 (IL-6). Associations between factors and time to mortality by 90 days were assessed using univariate and multivariable Cox proportional hazards models. RESULTS: Viral Ag ≥4500â ng/L (vs <200â ng/L; adjusted hazard ratio [aHR], 2.07; 1.29-3.34), viral RNA (<35 000â copies/mL [aHR, 2.42; 1.09-5.34], ≥35 000â copies/mL [aHR, 2.84; 1.29-6.28], vs below detection), respiratory support (<4 L O2 [aHR, 1.84; 1.06-3.22]; ≥4 L O2 [aHR, 4.41; 2.63-7.39], or noninvasive ventilation/high-flow nasal cannula [aHR, 11.30; 6.46-19.75] vs no oxygen), renal impairment (aHR, 1.77; 1.29-2.42), and IL-6 >5.8â ng/L (aHR, 2.54 [1.74-3.70] vs ≤5.8â ng/L) were significantly associated with mortality risk in final adjusted analyses. Viral Ag, viral RNA, and IL-6 were not measured in real-time. CONCLUSIONS: Baseline virus-specific, clinical, and biological variables are strongly associated with mortality risk within 90 days, revealing potential pathogen and host-response therapeutic targets for acute COVID-19 disease.

Taking leftover prescribed antibiotics without consulting a healthcare professional is problematic for the efficacy, safety, and antibiotic stewardship. We conducted a cross-sectional survey of adult patients in English and Spanish between January 2020 and June 2021 in six safety-net primary care clinics and two private emergency departments. We assessed the reasons for stopping prescribed antibiotics early and what was done with the leftover antibiotics. Additionally, we determined 1) prior leftover antibiotic use, 2) intention for future use of leftover antibiotics, and 3) sociodemographic factors. Of 564 survey respondents (median age of 51), 45% (251/564) reported a history of stopping antibiotics early, with 171/409 (42%) from safety net and 80/155 (52%) from the private clinics. The most common reason for stopping prescribed antibiotics early was "because you felt better" (194/251, 77%). Among survey participants, prior use of leftover antibiotics was reported by 149/564 (26%) and intention for future use of leftover antibiotics was reported by 284/564 (51%). In addition, higher education was associated with a higher likelihood of prior leftover use. Intention for future use of leftover antibiotics was more likely for those with transportation or language barriers to medical care and less likely for respondents with private insurance. Stopping prescribed antibiotics early was mostly ascribed to feeling better, and saving remaining antibiotics for future use was commonly reported. To curb nonprescription antibiotic use, all facets of the leftover antibiotic use continuum, from overprescribing to hoarding, need to be addressed.

BACKGROUND: Risk factors for ciprofloxacin or MDR in primary care urine specimens are not well defined. OBJECTIVES: We created a primary care-specific antibiogram for Escherichia coli isolates from cases with complicated and uncomplicated urinary tract infection (UTI) and evaluated risk factors for ciprofloxacin, trimethoprim/sulfamethoxazole and MDR among Enterobacterales. METHODS: We conducted a cross-sectional study to determine resistance and risk factors by collecting urine cultures from all patients (≥18 years) presenting with provider-suspected UTI at two primary care, safety-net clinics in Houston, TX, USA between November 2018 and March 2020. RESULTS: Among 1262 cultures, 308 cultures grew 339 uropathogens. Patients with Enterobacterales (nâ=â199) were mostly female (93.5%) with a mean age of 48.5 years. E. coli was the predominant uropathogen isolated (nâ=â187/339; 55%) and had elevated trimethoprim/sulfamethoxazole (43.6%) and ciprofloxacin (29.5%) resistance, low nitrofurantoin (1.8%) resistance, and no fosfomycin resistance. Among E. coli, 10.6% were ESBL positive and 24.9% had MDR. Birth outside the U.S.A., prior (2 year) trimethoprim/sulfamethoxazole resistance, and diabetes mellitus were associated with trimethoprim/sulfamethoxazole resistance. Prior (60 day) fluoroquinolone use, prior ciprofloxacin resistance and both diabetes mellitus and hypertension were strongly associated with ciprofloxacin resistance. Prior fluoroquinolone use and a history of resistance to any studied antibiotic were associated with MDR, while pregnancy was protective. CONCLUSIONS: We found elevated resistance to UTI-relevant antimicrobials and novel factors associated with resistance; these data can be incorporated into clinical decision tools to improve organism and drug concordance.

PURPOSE: Recurrent cystitis guidelines recommend relying on a local antibiogram or prior urine culture to guide empirical prescribing, yet little data exist to quantify the predictive value of a prior culture. We constructed a urinary antibiogram and evaluated test metrics (sensitivity, specificity, and Bayes' positive and negative predictive values) of a prior gram-negative organism on predicting subsequent resistance or susceptibility among patients with uncomplicated, recurrent cystitis. MATERIALS AND METHODS: We performed a retrospective database study of adults with recurrent, uncomplicated cystitis (cystitis occurring 2 times in 6 months or 3 times in 12 months) from urology or primary care clinics between November 1, 2016, and December 31, 2018. We excluded pregnant females, patients with complicated cystitis, or pyelonephritis. Test metrics were calculated between sequential, paired cultures using standard formulas. RESULTS: We included 597 visits from 232 unique patients wherein 310 (51.2%) visits had a urine culture and 165 had gram-negative uropathogens isolated. Patients with gram-negative uropathogens were mostly females (97%), with a median age of 58.5 years. Our antibiogram found 38.0%, 27.9%, and 5.5% of Escherichia coli isolates had resistance to trimethoprim-sulfamethoxazole, ciprofloxacin, and nitrofurantoin, respectively. Prior cultures (within 2 years) had good predictive value for detecting future susceptibility to first-line agents nitrofurantoin (0.85) and trimethoprim-sulfamethoxazole (0.78) and excellent predictive values (≥0.90) for cefepime, ceftriaxone, cefuroxime, ciprofloxacin, levofloxacin, gentamicin, tobramycin, piperacillin-tazobactam, and imipenem. CONCLUSIONS: Considerable antibiotic resistance was detected among E coli isolates in patients with recurrent, uncomplicated cystitis. Using a prior culture as a guide can enhance the probability of selecting an effective empirical agent.

BACKGROUND: Using antibiotics without a prescription is potentially unsafe and may increase the risk of antimicrobial resistance. We evaluated the effect of patient, health system, and clinical encounter factors on intention to use antibiotics without a prescription that were (1) purchased in the United States, (2) obtained from friends or relatives, (3) purchased abroad, or (4) from any of these sources. METHODS: The survey was performed January 2020-June 2021 in 6 publicly funded primary care clinics and 2 private emergency departments in Texas, United States. Participants included adult patients visiting 1 of the clinical settings. Nonprescription use was defined as use of antibiotics without a prescription; intended use was professed intention for future nonprescription antibiotic use. RESULTS: Of 564 survey respondents (33% Black and 47% Hispanic or Latino), 246 (43.6%) reported prior use of antibiotics without a prescription, and 177 (31.4%) reported intent to use antibiotics without a prescription. If feeling sick, respondents endorsed that they would take antibiotics obtained from friends/relatives (22.3% of 564), purchased in the United States without a prescription (19.1%), or purchased abroad without a prescription (17.9%). Younger age, lack of health insurance, and a perceived high cost of doctor visits were predictors of intended use of nonprescription antibiotics from any of the sources. Other predictors of intended use were lack of transportation for medical appointments, language barrier to medical care, Hispanic or Latino ethnicity, and being interviewed in Spanish. CONCLUSIONS: Patients without health insurance who report a financial barrier to care are likely to pursue more dangerous nonprescription antimicrobials. This is a harm of the US fragmented, expensive healthcare system that may drive increasing antimicrobial resistance and patient harm.

BACKGROUND: Antimicrobial resistance (AMR) is undermining modern medicine, a problem compounded by bacterial adaptation to antibiotic pressures. Phages are viruses that infect bacteria. Their diversity and evolvability offer the prospect of their use as a therapeutic solution. Reported are outcomes of customized phage therapy for patients with difficult-to-treat antimicrobial resistant infections. METHODS: We retrospectively assessed 12 cases of customized phage therapy from a phage production center. Phages were screened, purified, sequenced, characterized, and Food and Drug Administration-approved via the IND (investigational new drug) compassionate-care route. Outcomes were assessed as favorable or unfavorable by microbiologic and clinical standards. Infections were device-related or systemic. Other experiences such as time to treatment, antibiotic synergy, and immune responses were recorded. RESULTS: Fifty requests for phage therapy were received. Customized phages were generated for 12 patients. After treatment, 42% (5/12) of cases showed bacterial eradication and 58% (7/12) showed clinical improvement, with two-thirds of all cases (66%) showing favorable responses. No major adverse reactions were observed. Antibiotic-phage synergy in vitro was observed in most cases. Immunological neutralization of phages was reported in 5 cases. Several cases were complicated by secondary infections. Complete characterization of the phages (morphology, genomics, and activity) and their production (methods, sterility, and endotoxin tests) are reported. CONCLUSIONS: Customized phage production and therapy was safe and yielded favorable clinical or microbiological outcomes in two-thirds of cases. A center or pipeline dedicated to tailoring the phages against a patient's specific AMR bacterial infection may be a viable option where standard treatment has failed.

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.

Urinary tract infections (UTI) are one of the most common indications for antibiotic prescriptions in the outpatient setting. Given rising rates of antibiotic resistance among uropathogens, antibiotic stewardship is critically needed to improve outpatient antibiotic use, including in outpatient clinics (primary care and specialty clinics) and emergency departments. Outpatient clinics are in general a neglected practice area in antibiotic stewardship programs, yet most antibiotic use in the United States is in the outpatient setting. This article provides a comprehensive review of antibiotic stewardship strategies for outpatient UTI in the adult population, with a focus on the "five Ds" of stewardship for UTI, including right diagnosis, right drug, right dose, right duration, and de-escalation. Stewardship interventions that have shown success for improving prescribing for outpatient UTI are discussed, including diagnostic stewardship strategies, such as reflex urine cultures, computerized decision support systems, and modified reporting of urine culture results. Among the many challenges to achieving stewardship for UTI in the outpatient setting, some of the most important are diagnostic uncertainty, increasing antibiotic resistance, limitations of guidelines, and time constraints of stewardship personnel and front-line providers. This article presents a stewardship framework, built on current evidence and expert opinion, that clinicians can use to guide their own outpatient management of UTI.

BACKGROUND: Urine cultures are nonspecific and often lead to misdiagnosis of urinary tract infection and unnecessary antibiotics. Diagnostic stewardship is a set of procedures that modifies test ordering, processing, and reporting in order to optimize diagnosis and downstream treatment. In this study, we aimed to develop expert guidance on best practices for urine culture diagnostic stewardship. METHODS: A RAND-modified Delphi approach with a multidisciplinary expert panel was used to ascertain diagnostic stewardship best practices. Clinical questions to guide recommendations were grouped into three thematic areas (ordering, processing, reporting) in practice settings of emergency department, inpatient, ambulatory, and long-term care. Fifteen experts ranked recommendations on a 9-point Likert scale. Recommendations on which the panel did not reach agreement were discussed during a virtual meeting, then a second round of ranking by email was completed. After secondary review of results and panel discussion, a series of guidance statements was developed. RESULTS: One hundred and sixty-five questions were reviewed. The panel reaching agreement on 104, leading to 18 overarching guidance statements. The following strategies were recommended to optimize ordering urine cultures: requiring documentation of symptoms, sending alerts to discourage ordering in the absence of symptoms, and cancelling repeat cultures. For urine culture processing, conditional urine cultures and urine white blood cell count as criteria were supported. For urine culture reporting, appropriate practices included nudges to discourage treatment under specific conditions and selective reporting of antibiotics to guide therapy decisions. CONCLUSIONS: These 18 guidance statements can optimize use of urine cultures for better patient outcomes.

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.

OBJECTIVE: This systematic review aims to assess what is known about convalescence following abdominal surgery. Through a review of the basic science and clinical literature, we explored the effect of physical activity on the healing fascia and the optimal timing for postoperative activity. BACKGROUND: Abdominal surgery confers a 30% risk of incisional hernia development. To mitigate this, surgeons often impose postoperative activity restrictions. However, it is unclear whether this is effective or potentially harmful in preventing hernias. METHODS: We conducted 2 separate systematic reviews using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The first assessed available basic science literature on fascial healing. The second assessed available clinical literature on activity after abdominal surgery. RESULTS: Seven articles met inclusion criteria for the basic science review and 22 for the clinical studies review. The basic science data demonstrated variability in maximal tensile strength and time for fascial healing, in part due to differences in layer of abdominal wall measured. Some animal studies indicated a positive effect of physical activity on the healing wound. Most clinical studies were qualitative, with only 3 randomized controlled trials on this topic. Variability was reported on clinician recommendations, time to return to activity, and factors that influence return to activity. Interventions designed to shorten convalescence demonstrated improvements only in patient-reported symptoms. None reported an association between activity and complications, such as incisional hernia. CONCLUSIONS: This systematic review identified gaps in our understanding of what is best for patients recovering from abdominal surgery. Randomized controlled trials are crucial in safely optimizing the recovery period.

OBJECTIVE: Effective diabetic foot ulcer (DFU) care has been stymied by a lack of input from patients and caregivers, reducing treatment adherence and overall quality of care. Our objectives were to capture the patient and caregiver perspectives on experiencing a DFU and to improve prioritization of patient-centered outcomes. METHODS: A DFU-related stakeholder group was formed at an urban tertiary care center. Seven group meetings were held across 4 months, each lasting â¼1 hour. The meeting facilitator used semistructured questions to guide each discussion. The topics assessed the challenges of the current DFU care system and identified the outcomes most important to stakeholders. The meetings were audio recorded and transcribed. Directed and conventional content analyses were used to identify key themes. RESULTS: Six patients with diabetes (five with an active DFU), 3 family caregivers, and 1 Wound Clinic staff member participated in the stakeholder group meetings. The mean patient age was 61 years, four (67%) were women, five (83%) were either African American or Hispanic, and the mean hemoglobin A1c was 8.3%. Of the five patients with a DFU, three had previously required lower extremity endovascular treatment and four had undergone at least one minor foot amputation. Overall, stakeholders described how poor communication between medical personnel and patients made the DFU experience difficult. They felt overwhelmed by the complexity of DFU care and were persistently frustrated by inconsistent medical recommendations. Limited resources further exacerbated their frustrations and barriers to care. To improve DFU management, the stakeholders suggested a centralized healthcare delivery pathway with timely access to a coordinated, multidisciplinary DFU team. The clinical outcomes most valued by stakeholders were (1) avoiding amputation and (2) maintaining or improving health-related quality of life, which included independent mobility, pain control, and mental health. From these themes, we developed a conceptual model to inform DFU care pathways. CONCLUSIONS: Current DFU management lacks adequate care coordination. Multidisciplinary approaches tailored to the self-identified needs of patients and caregivers could improve adherence. Future DFU-related comparative effectiveness studies will benefit from direct stakeholder engagement and are required to evaluate the efficacy of incorporating patient-centered goals into the design of a multidisciplinary DFU care delivery system.

We question the reliability of the vague symptoms that most commonly define catheter-associated urinary tract infection (CAUTI) and encourage further examination of whether the current CAUTI definition reflects a true infection. While diagnosing CAUTI using the current surveillance definition, physicians may be missing a number of nonurinary etiologies for fever, prematurely diagnosing urinary tract infection, and prescribing unnecessary antibiotics. We believe it is time to reconsider the quality metric of CAUTI. By doing so, we can improve antibiotic use and quality of patient care.

Background: Use of antibiotics without a prescription may increase unnecessary and inappropriate drug use or doses as well as global risk for antimicrobial resistance. Purpose: To perform a scoping review of research on the prevalence of nonprescription antibiotic use in the United States and to examine the factors that influence it. Data Sources: Searches of PubMed, EMBASE, CINAHL, Scopus, and relevant Web sites without language restrictions from January 2000 to March 2019. Study Selection: Studies reporting nonprescription use of antibiotics, storage of antibiotics, intention to use antibiotics without a prescription, and factors influencing nonprescription use. Data Extraction: Two reviewers independently screened citations and full texts and performed data abstraction. Data Synthesis: Of 17 422 screened articles, 31 met inclusion criteria. Depending on population characteristics, prevalence of nonprescription antibiotic use varied from 1% to 66%, storage of antibiotics for future use varied from 14% to 48%, and prevalence of intention to use antibiotics without a prescription was 25%. Antibiotics were obtained without a prescription from various sources, including previously prescribed courses, local markets or stores, and family or friends. Reported factors contributing to nonprescription use included easy access through markets or stores that obtain antibiotics internationally for under-the-counter sales, difficulty accessing the health care system, costs of physician visits, long waiting periods in clinics, and transportation problems. Limitation: Scarce evidence and heterogeneous methods and outcomes. Conclusion: Nonprescription antibiotic use is a seemingly prevalent and understudied public health problem in the United States. An increased understanding of risk factors and pathways that are amenable to intervention is essential to decrease this unsafe practice. Primary Funding Source: None.

Several studies have indicated that fluoroquinolone use may be associated with an increased risk of aortic aneurysm or dissection (AAD). Because patients with AAD or Marfan syndrome are at increased risk for aortic rupture, we performed a retrospective cohort study to determine the prevalence of systemic fluoroquinolone exposure and predictors of fluoroquinolone use in these patients. Data were obtained from the advisory board billing and administrative database, which contained information on 22 million adult hospitalizations in the United States for the study period (2009 to 2015). International Classification of Diseases (9/10) and Current Procedural Terminology codes were used to identify patients who had AAD or Marfan syndrome or underwent aortic repair. We identified 136,789 admissions for AAD, which involved 99,818 unique patients, 20% of whom received fluoroquinolone during a hospital admission. Of the 7,045 patients with dissection, 18% were exposed to fluoroquinolone. Of the 27,876 AAD patients who underwent aortic repair, 19% received fluoroquinolone during a hospitalization before the repair. In the AAD patients, having a diagnosis of pneumonia or urinary tract infection increased the likelihood of receiving fluoroquinolone during admission by 46% and 40%, respectively (P < 0.001). Additionally, we identified 2,871 admissions for Marfan syndrome, which involved 1,872 patients, 14% of whom received fluoroquinolone during an admission. In these patients, pneumonia and urinary tract infections also increased the risk of fluoroquinolone exposure. If the deleterious effects of fluoroquinolone on aortic integrity are substantiated, reducing fluoroquinolone use in hospitalized patients with aortic disorders will become an urgent safety issue for antibiotic stewardship programs.

OBJECTIVES: To determine the rates of emergency department (ED) visits and inpatient hospitalizations for genitourinary (GU) complications after spinal cord injury (SCI) using a national sample; to examine which patient and facility factors are associated with inhospital mortality; and to estimate direct medical costs of GU complications after SCI. DESIGN: Retrospective cross-sectional and cost analysis of the 2006 to 2015 National Inpatient Sample and National Emergency Department Sample from the Healthcare Cost and Utilization Project. PARTICIPANTS: SCI-related encounters using various International Classification of Disease, Ninth Edition, Clinical Modification diagnosis codes. The inpatient sample included 1,796,624 hospitalizations, and the ED sample included 618,118 treat-and-release visits. MAIN OUTCOME MEASURES: The exposure included a GU complication, identified by International Classification of Disease, Ninth Edition, Clinical Modification codes 590-599. The outcomes then included an ED visit or hospitalization, death prior to discharge, and direct medical costs estimated from reported hospital charges. RESULTS: For the inpatient sample, we observed a 2.5% annual increase (95% confidence interval [CI], 1.8-3.2) in the proportion of SCI-related hospitalizations with any GU complication from 2006 to 2011, and a lesser rate of increase of 0.9% (95% CI, 0.4-1.4) each year from 2011 to 2015. Age, level of injury, and payer source were correlated to inhospital mortality. The costs of GU-related health care use exceeded $4 billion over the study period. CONCLUSIONS: This study shows the rates and economic burden of health care use associated with GU complications in persons with SCI in the United States. The need to develop strategies to effectively deliver health care to the SCI population for these conditions remains great.

OBJECTIVE: The objective of this study was to evaluate a new academic relative-value unit (aRVU) scoring system linked to faculty compensation and analyze its association with overall departmental academic productivity. SUMMARY BACKGROUND DATA: Faculty are often not incentivized or financially compensated for educational and research activities crucial to the academic mission. METHODS: We launched an online, self-reporting aRVU system in 2015 to document and incentivize the academic productivity of our faculty. The system captured 65 specific weighted scores in 5 major categories of research, education, innovation, academic service, and peer review activities. The aRVU scores were rank-aggregated annually, and bonuses were distributed to faculty members in 3 tiers: top 10%, top third, and top half. We compared pre-aRVU (academic year 2015) to post-aRVU (academic year 2017) departmental achievement metrics. RESULTS: Since 2015, annual aRVU bonuses totaling $493,900 were awarded to 59 faculty members (58% of eligible department faculty). Implementing aRVUs was associated with significant increases in several key departmental academic achievement metrics: presentations (579 to 862; P = 0.02; 49% increase), publications (390 to 446; P = 0.02; 14%), total research funding ($4.6âM to $8.4âM; P < 0.001; 83%), NIH funding ($0.6âM to $3.4âM; P < 0.001; 467%), industry-sponsored clinical trials (8 to 23; P = 0.002; 188%), academic society committee positions (226 to 298; P < 0.001; 32%), and editorial leadership positions (50 to 74; P = 0.01; 48%). CONCLUSIONS: Implementing an aRVU system was associated with increases in departmental academic productivity. Although other factors undoubtedly contributed to these increases, an aRVU program may represent an important mechanism for tracking and rewarding academic productivity in surgery departments.

Background: Overuse of urine testing is a driver of inappropriate antimicrobial use. Limiting wasteful testing is important for patient safety. We examined the national prevalence and patterns of urine testing during adult inpatient admission in the United States. Methods: We performed a retrospective cohort study using a national dataset of inpatient admissions from 263 hospitals in the United States from 2009 to 2014. We included all adult inpatient admissions, excluding those related to pregnancy, urology procedures, and with lengths of stay >30 days. A facility-level fixed-effects quasi-Poisson regression model was used to examine the incidence of urinalysis and urine culture testing for select diagnoses and patient factors. Results: The cohort included 4473655 admissions. Charges for urinalysis were present for 2086697 (47%) admissions, with 584438 (13%) including >1 urinalysis. Charges for urine culture were present for 1197242 (27%) admissions, with 246211 (6%) having >1 culture. Urine culture testing varied by principal diagnosis. Heart failure and acute myocardial infarction had 29% and 35% fewer cultures sent on the first day of admission compared to all other admissions (P < .001). Female sex and receipt of antibiotics during the hospital admission consistently predicted increased culture testing, regardless of principal diagnosis or age. Conclusions: Urine testing was common and frequently repeated during inpatient admission, suggesting large-scale overuse. The variation in testing by diagnosis suggests that clinical presentation modifies test use. The sex bias in urine testing is not clinically supported and must be addressed in interventions aimed at reducing excess urine testing.
