Ceftazidime/avibactam alone or in combination with an aminoglycoside for treatment of carbapenem-resistant Enterobacterales infections: a retrospective cohort study.

BACKGROUND: Ceftazidime/avibactam is one of the preferred treatment options for carbapenem-resistant Enterobacterales (CRE). However, the benefit of combining ceftazidime/avibactam with another antibiotic remains unclear. OBJECTIVES: To identify variables associated with treatment failure during the use of ceftazidime/avibactam for CRE infections and assess the effect of combining an aminoglycoside with ceftazidime/avibactam. METHODS: This was a retrospective cohort study of patients with a positive CRE culture treated with ceftazidime/avibactam between 2015 and 2021 in 134 Veterans Affairs (VA) facilities. The primary outcome was 30-day mortality and the secondary outcome was in-hospital mortality. A subanalysis in patients who received an aminoglycoside was also performed. RESULTS: A total of 303 patients were included. The overall 30-day and in-hospital mortality rates were 12.5% and 24.1%, respectively. Age (aOR 1.052, 95% CI 1.013-1.093), presence in the ICU (aOR 2.704, 95% CI 1.071-6.830), and receipt of an aminoglycoside prior to initiation of ceftazidime/avibactam (aOR 4.512, 95% CI 1.797-11.327) were independently associated with 30-day mortality. In the subgroup of patients that received an aminoglycoside (n=77), their use in combination with ceftazidime/avibactam had a 30-day mortality aOR of 0.321 (95% CI, 0.089-1.155). CONCLUSIONS: In veterans treated with ceftazidime/avibactam for CRE infections, increased age, receipt of an empiric aminoglycoside, and presence in the ICU at the time of index culture were associated with higher 30-day mortality. Among patients who received an aminoglycoside, their use in combination with ceftazidime/avibactam trended toward protectiveness of 30-day mortality, suggesting a potential role for this combination to treat CRE infections in patients who are more severely ill.

Antibiotic utilization trends in Veterans Affairs patients with Stenotrophomonas maltophilia bloodstream infections.

Objective: Stenotrophomonas maltophilia is a multidrug-resistant gram-negative bacillus that can cause serious infections but has limited treatment options. This study aims to establish trends in the treatment of S. maltophilia bloodstream infections (BSI) across the United States in Department of Veterans Affairs (VA) facilities. Methods: Data was evaluated over a 10-year timeframe (2012 to 2021) in this retrospective cohort study. Veterans with ≥ 1 blood culture with S. maltophilia within a VA medical encounter were included. Microbiology, pharmacy, and patient information were collected through national VA data sources and chart review. Descriptive statistics and Poisson regression were used to summarize patient demographics, facility characteristics, microbiologic data, and treatment trends. Results: A total of 374 blood cultures positive for S. maltophilia were identified across 75 VA facilities. Of 282 unique patients with BSI, the majority were male (93.6%), white (67.4%), with a mean age of 64 ± 13.1 years. Of those patients, 78% received treatment, 12.8% had a polymicrobial blood culture, and 5.3% had a documented sulfa allergy. Susceptibility results were most reported for trimethoprim-sulfamethoxazole (TMP-SMX), levofloxacin, and ceftazidime, with 4.5%, 4.3%, and 44.4% resistant isolates, respectively. Antibiotics most prescribed included TMP-SMX (41.5%) and levofloxacin (39.4%), followed by ciprofloxacin (13.8%) and ceftazidime (12.4%). Combination therapy was prescribed in 33% of patients. No significant trends were found with antibiotic utilization over time. Conclusions: TMP-SMX and levofloxacin were the most prescribed antibiotics for S. maltophilia BSI treatment. No significant changes were seen with antibiotic prescribing trends in Veterans from 2012 to 2021.

Race, Social Determinants of Health, and the Quality of Diabetic Eye Care.

Importance: Besides race, little is known about how other social determinants of health (SDOH) affect quality of diabetic eye care. Objective: To evaluate the association between multiple SDOH and monitoring for diabetic retinopathy (DR) in accordance with clinical practice guidelines (CPGs). Design, Setting, and Participants: This cohort study was conducted in 11 US medical centers and included adult patients (18-75 years old) with diabetes. Patients received care from 2012 to 2023 and had 18 months or more of follow-up. Exposures: Multiple SDOH and associated factors, including ethnicity, urbanicity of residence, health insurance type, and diabetes type. Main Outcomes and Measures: Adjusted odds ratio (aOR) of receiving 1 or more eye-care visits and 1 or more dilated fundus examinations in accordance with CPGs. Results: The study cohort included 37 397 adults with diabetes: 10 157 Black patients and 27 240 White patients. The mean (SD) age was 58 (11) years for Black patients and 59 (11) years for White patients. Of the Black patients, 6422 (63.2%) were female and 3735 (36.8%) male; of the White patients, 13 120 (48.1) were female and 14 120 (51.8) were male. Compared with those of the same race in urban communities, Black patients (aOR, 0.12; 95% CI, 0.04-0.31) and White patients (aOR, 0.75; 95% CI, 0.62-0.91) with diabetes living in rural communities had 88% and 25% lower odds of having eye-care visits, respectively. Sicker Black and White patients, defined by the Charlson Comorbidity Index, had 4% (aOR, 1.04; 95% CI, 1.02-1.06) and 5% (aOR, 1.05, CI 1.04-1.06) higher odds of having an eye-care visit, respectively. Black patients with preexisting DR had 15% lower odds of visits (aOR, 0.85, CI 0.73-0.99) compared with those without preexisting DR while White patients with preexisting DR had 16% higher odds of eye-care visits (aOR, 1.16; 95% CI, 1.05-1.28). White patients with Medicare (aOR, 0.85; 95% CI, 0.80-0.91) and Medicaid (aOR, 0.81; 95% CI, 0.68-0.96) had lower odds of eye-care visits vs patients with commercial health insurance. Hispanic White patients had 15% lower odds of eye-care visits (aOR, 0.85; 95% CI, 0.74-0.98) vs non-Hispanic White patients. White patients with type 1 diabetes had 17% lower odds of eye-care visits (aOR, 0.83; 95% CI, 0.76-0.90) vs those with type 2 diabetes. Among patients who had eye-care visits, those with preexisting DR (Black: aOR, 1.68; 95% CI, 1.11-2.53; White: aOR, 1.51; 95% CI, 1.16-1.96) were more likely to undergo dilated fundus examinations. Conclusions and Relevance: This study found that certain SDOH affected monitoring for DR similarly for Black and White patients with diabetes while others affected them differently. Patients living in rural communities, Black patients with preexisting DR, and Hispanic White patients were not receiving eye care in accordance with CPGs, which may contribute to worse outcomes.

Pattern of admissions and needs assessment for palliative care services among in-patients in a tertiary health facility in South-Western Nigeria.

BACKGROUND: Palliative care evolution focuses on education and medication accessibility. As little as 12% of palliative care needs are met. Assessment of the domains of Palliative care and patients' and families' experience are essential in life-limiting conditions. The Lagos University Teaching Hospital (LUTH), have the National Cancer Centre without offering palliative care services. AIM: The aim was to examine pattern of admissions and needs assessment for palliative services among patients admitted into LUTH wards. MATERIALS AND METHOD: Responses were entered into a data sheet inputted into Epi info version 7.2. Descriptive characteristics of the participants were presented as frequencies and percentages for age, sex, pattern of disease, domains of Palliative care, Advance care Plan, Preparation for home care, death and Education about the illness and category of medical conditions (palliative and non-palliative conditions). Together for Short Lives (TfSL) tool was used to categorize respondents' conditions into Palliative and Non-palliative conditions. Chi-square test was used to determine association between independent variables (pattern of diagnoses, stage of disease, advanced care plan, preparation for home care/ death and education on illness) and dependent variables (category of medical condition). Chi-square test was also used to explore the association between specialty of the managing doctor (independent variable) and Advance care plan (dependent variable). The level of statistical significance was P-value < 0.05. RESULTS: 80.6% of the respondents had palliative care conditions, 83.7% had family members as their caregiver while 13.2% of the participants had no caregiver and 65.9% had no advance care plan. There was no preparation for home care or death in 72.1%, 70.5% had education about their illness, and 68.2% were in the advanced stage of their disease. Participants attending the surgery non-trauma unit (51.6%) were more likely to have advance care plans. Adults were more likely to have palliative care conditions (79.8%) compared to children (20.2%), and was statistically significant. CONCLUSION: Majority of the participants need palliative care services but are unavailable and unmet and the most predominant condition was cancer. Majority had no advance care plan or preparation for home care or death despite having advanced stage of the disease. This survey emphasized the need for symptom management, communication and provision of support.

The effect of antibiotic premedication on postoperative complications following dental extractions.

OBJECTIVES: We aimed to evaluate the association between antibiotic prophylaxis and adverse outcomes following tooth extraction within the Veterans Affairs Healthcare System. METHODS: We conducted a retrospective cohort study of patients undergoing dental extractions in 2015-2019. The primary exposure was antibiotic prophylaxis. The primary outcome was post-extraction complication within 7 days (e.g., alveolar osteitis and surgical site infection); the secondary outcome was subsequent medical care relating to a post-extraction oral complication within 7 days. Multivariable logistic regression models assessed the independent effect of antibiotic prophylaxis on each outcome. RESULTS: Of 385,880 visits with a dental extraction, 122,810 (31.8%) received antibiotic prophylaxis. Overall, 3387 (0.9%) experienced a post-extraction complication and 350 (0.09%) received medical care relating to a post-extraction oral complication within 7 days. In multivariable regression, diabetes was a statistically significant (p = 0.01) effect modifier of the association between antibiotic prophylaxis and post-extraction complication. Among visits for patients without diabetes, antibiotic prophylaxis was significantly associated with an increased odds of post-extraction complication (odds ratio [OR] = 1.25, 95% confidence interval [CI]: 1.13-1.38), but among visits for patients with diabetes no significant effect was observed (OR = 1.03, 95% CI: 0.92-1.15). Antibiotic prophylaxis was not significantly associated with post-extraction medical care (OR = 1.04; 95% CI: 0.83-1.30). CONCLUSIONS: In this large retrospective cohort, we observed no significant protective effect of antibiotic prophylaxis on post-extraction complications or subsequent medical care utilization in a setting with low complication rates. These data suggest that use of antibiotic prophylaxis in similar settings may need to be re-evaluated to minimize unnecessary antibiotic use.

Infection preventionists' current and preferred training strategies and tools.

BACKGROUND: Educating health care staff on infection prevention and control (IPC) is an essential role of infection preventionists (IPs), but the COVID-19 pandemic diverted resources away from IPC education. METHODS: Association for Professionals in Infection Control and Epidemiology members were invited to complete an online survey from spring 2023 to assess current and preferred approaches and tools for training health care personnel on IPC. Vendors, retirees, APIC staff, or those not working in health care or public health were excluded. RESULTS: In all, 2,432 IPs participated. IPs were more likely to report engaging in impromptu health care worker training (ie, just-in-time teaching and team huddles) versus planned educational activities (ie, learning modules, formal presentations, train-the-trainer, or simulation; Kruskal-Wallis = 288, P < .001). IPs' top preferred teaching methodologies included simulation or interactive activity, and their lowest preferred approach was independent learning modules. IPC training apps were frequently requested technology. DISCUSSION: IPs ranked simulation as their top preferred teaching method; however, simulation was one of the least frequently used approaches. IP education should include strategies for delivering effective impromptu training and how to develop and implement interactive simulation-based education. CONCLUSIONS: The expressed needs and preferences of IPs should be considered when developing IPC-related teaching and training tools.

A mixed-methods analysis of provider-documented and patient-reported urinary tract infection symptoms among veterans with neurogenic bladder.

ABSTRACT: Inappropriate urinary tract infection (UTI) diagnosis in patients with neurogenic bladder (NB) may result from ambiguous symptoms experienced by these patients and contributes to antibiotic overuse. Characterization of patient-reported signs and symptoms may help providers more appropriately diagnose UTIs. A previous study collected signs and symptoms recorded in electronic medical records (EMR) of patients with NB due to spinal cord injury/disorder (SCI/D), multiple sclerosis (MS), and Parkinson's Disease (PD) with at least one UTI diagnosis between 2017-2018 at four medical centers. In this study, twenty-three Veterans from this cohort with UTI diagnoses in the prior year participated in focus groups conducted May 2021 - May 2022. Transcripts were coded using mixed deductive and inductive coding. Qualitative data were compared to EMR data to give a comprehensive picture of signs and symptoms. Both providers and patients attributed non-specific symptoms like urine changes to UTI, but there was discordance between patients and providers in the identification of other signs and symptoms. Several patients described providers disregarding symptoms other than fever or chills. Optimizing UTI care for patients with NB could involve improving patient provider communication about UTI signs and symptoms and emphasizing thorough elicitation and evaluation of all signs and symptoms.

Feasibility, acceptability, and efficacy of a positive emotion regulation intervention to promote resilience for healthcare workers during the COVID-19 pandemic: A randomized controlled trial.

INTRODUCTION: Burnout poses a substantial, ongoing threat to healthcare worker (HCW) wellbeing and to the delivery of safe, quality healthcare. While systemic and organization-level changes in healthcare are critically important, HCWs also need individual-level skills to promote resilience. The objective of this trial is to test feasibility, acceptability, and efficacy of PARK, an online self-guided positive affect regulation intervention, in a sample of healthcare workers during the COVID-19 pandemic. DESIGN AND METHODS: In the context of the unprecedented rise in burnout during the COVID-19 pandemic, we conducted a randomized waitlist-controlled trial of the Positive Affect Regulation sKills (PARK) program-a five-week, online, self-guided coping skills intervention nested within an ongoing cohort of HCWs. N = 554 healthcare workers were randomly assigned to receive the intervention immediately or to receive the intervention after approximately 12 weeks. Outcomes included change in burnout, emotional wellbeing (positive affect, meaning and purpose, depression, anxiety) and sleep over approximately 12 weeks. Analyses included mixed-effects linear regression models comparing change over time in outcomes between intervention and control conditions. RESULTS: One third (n = 554) of the participants in the cohort of HCWs consented to participate and enrolled in PARK in April 2022. Compared to those who did not enroll, participants in the trial reported higher burnout, poorer emotional wellbeing, and poorer sleep at baseline (April, 2022; all ps < .05). Intent-to-treat analyses showed that participants randomly assigned to the intervention immediately (PARK-Now) improved significantly on anxiety (within-group change on PROMIS T-score = -0.63; p = .003) whereas those in the waitlist (PARK-Later) did not (within group T-score change 0.04, p = 0.90). The between-group difference in change, however, was not statistically significant (B = -0.67 p = 0.10). None of the other wellbeing outcomes changed significantly in the intervention group compared to the waitlist. Additional as-treated analyses indicated that those participants who completed all 5 of the weekly online lessons (N = 52; 9.4%) improved significantly more on the primary outcome of positive affect compared to those who enrolled in PARK but completed zero lessons (n = 237; 42.8%; B = 2.85; p = .0001). CONCLUSIONS: Online self-guided coping skills interventions like PARK can be effective in targeted samples and future work will focus on adaptations to increase engagement and tailor PARK for HCWs who could most benefit.

Utilization of at-home tests for coronavirus disease 2019 (COVID-19) among healthcare workers in Chicago.

Objective: To describe utilization of at-home coronavirus disease 2019 (COVID-19) testing among healthcare workers (HCW). Design: Serial cross-sectional study. Setting and participants: HCWs in the Chicago area. Methods: Serial surveys were conducted from the Northwestern Medicine (NM HCW SARS-CoV-2) Serology Cohort Study. In April 2022, participants reflected on the past 30 days to complete an online survey regarding COVID-19 home testing. Surveys were repeated in June and November 2022. The percentage of completed home tests and ever-positive tests were reported. Multivariable Poisson regression was used to calculate prevalence rate ratios (PRR) and univariate analysis was used for association between participant characteristics with home testing and positivity. Results: Overall, 2,226 (62.4%) of 3,569 responded to the survey in April. Home testing was reported by 26.6% of respondents and 5.9% reported having at least one positive home test. Testing was highest among those 30-39 years old (35.9%) and nurses (28.3%). A positive test was associated (P < .001) with exposure to people, other than patients with known or suspected COVID-19. Home testing increased in June to 36.4% (positivity 19.9%) and decreased to 25% (positivity 13.5%) by November. Conclusion: Our cohort findings show the overall increase in both home testing and ever positivity from April to November - a period where changes in variants of concern of SARS-CoV-2 were reported nationwide. Having an exposure to people, other than patients with known or suspected COVID-19 was significantly associated with both, higher home testing frequency and ever-test positivity.

Development and implementation of a nationwide multidrug-resistant organism tracking and alert system for Veterans Affairs medical centers.

OBJECTIVE: Develop and implement a system in the Veterans Health Administration (VA) to alert local medical center personnel in real time when an acute- or long-term care patient/resident is admitted to their facility with a history of colonization or infection with a multidrug-resistant organism (MDRO) previously identified at any VA facility across the nation. METHODS: An algorithm was developed to extract clinical microbiology and local facility census data from the VA Corporate Data Warehouse initially targeting carbapenem-resistant Enterobacterales (CRE) and methicillin-resistant Staphylococcus aureus (MRSA). The algorithm was validated with chart review of CRE cases from 2010-2018, trialed and refined in 24 VA healthcare systems over two years, expanded to other MDROs and implemented nationwide on 4/2022 as "VA Bug Alert" (VABA). Use through 8/2023 was assessed. RESULTS: VABA performed well for CRE with recall of 96.3%, precision of 99.8%, and F1 score of 98.0%. At the 24 trial sites, feedback was recorded for 1,011 admissions with a history of CRE (130), MRSA (814), or both (67). Among Infection Preventionists and MDRO Prevention Coordinators, 338 (33%) reported being previously unaware of the information, and of these, 271 (80%) reported they would not have otherwise known this information. By fourteen months after nationwide implementation, 113/130 (87%) VA healthcare systems had at least one VABA subscriber. CONCLUSIONS: A national system for alerting facilities in real-time of patients admitted with an MDRO history was successfully developed and implemented in VA. Next steps include understanding facilitators and barriers to use and coordination with non-VA facilities nationwide.

Facility- and patient-level factors associated with implementation of contact precautions in hospitalized VA patients with positive CRE cultures.

Decreasing the time to contact precautions (CP) is critical to carbapenem-resistant Enterobacterales (CRE) prevention. Identifying factors associated with delayed CP can decrease the spread from patients with CRE. In this study, a shorter length of stay was associated with being placed in CP within 3 days.

Barriers and facilitators to guideline concordant dental antibiotic prescribing in the United States: A qualitative study of the National Dental PBRN.

OBJECTIVES: While factors contributing to dental antibiotic overprescribing have previously been described, previous work has lacked any theoretical behavior change framework that could guide future intervention development. The purpose of this study was to use an evidence-based conceptual model to identify barriers and facilitators of appropriate antibiotic prescribing by dentists as a guide for future interventions aimed at modifying antibiotic prescribing. METHODS: Semi-structured interviews were conducted with dentists from the National Dental Practice Based Research Network (PBRN) exploring patient and practice factors perceived to impact antibiotic prescribing. Audio-recorded telephone interviews were transcribed and independently coded by three researchers. Themes were organized around the COM-B model to inform prospective interventions. RESULTS: 73 of 104 dentists (70.1%) were interviewed. Most were general dentists (86.3%), male (65.7%), and white (69.9%). Coding identified three broad targets to support appropriate dental antibiotic prescribing among dentists: (1) increasing visibility and accessibility of guidelines, (2) providing additional guidance on antibiotic prescribing in dental scenarios without clear guidelines, and (3) education and communication skills-building focused on discussing appropriate antibiotic use with patients and physicians. CONCLUSIONS: The findings from our study are consistent with other studies focusing on antibiotic prescribing behavior in dentists. Understanding facilitators and barriers to dental antibiotic prescribing is necessary to inform targeted interventions to improve appropriate antibiotic prescribing. Future interventions should focus on implementing multimodal strategies to provide the necessary support for dentists to judiciously prescribe antibiotics.

Knowledge, perceptions, and beliefs about urinary tract infections in persons with neurogenic bladder and impacts on interventions to promote person-centered care.

STUDY DESIGN: Qualitative study. OBJECTIVES: To explore how knowledge, perceptions, and beliefs about urinary tract infections (UTIs) among persons with neurogenic bladder (NB) may impact health behaviors and provider management and enhance person-centeredness of interventions to improve UTI management. SETTING: Three Veterans Affairs (VA) medical centers. METHODS: Adults with NB due to spinal cord injury/disorder (SCI/D) or multiple sclerosis (MS) with UTI diagnoses in the prior year participated in focus groups. Transcripts were coded using deductive codes linked to the Health Belief Model and inductive codes informed by grounded theory. RESULTS: Twenty-three Veterans (SCI/D, 78%; MS: 18.5%) participated in discussions. Three themes emerged: (1) UTI knowledge; (2) factors affecting the intervention environment; and (3) factors affecting modes of delivery. Knowledge gaps included UTI prevention, specific symptoms most indicative of UTI, and antibiotic side effects. Poor perceptions of providers lacking knowledge about NB and ineffective patient-provider communication were common in the Emergency Department and non-VA facilities, whereas participants had positive perceptions of home-based care. Participants perceived lower severity and frequency of antibiotic risks compared to UTI risks. Participant preferences for education included caregiver involvement, verbal and written materials, and diverse settings like peer groups. CONCLUSIONS: Identifying patient perspectives enhances person-centeredness and allows for novel interventions improving patient knowledge and behaviors about UTIs. Partnering with trusted providers and home-based caregivers and improving NB knowledge and communication in certain care settings were important. Patient education should address mental risk representations and incorporate preferences for content delivery to optimize self-efficacy and strengthen cues to action.

Risk factors for oral infection and dry socket post-tooth extraction in medically complex patients in the absence of antibiotic prophylaxis: A case-control study.

INTRODUCTION: Dry socket and infection are complications of tooth extractions. The objective was to determine risk factors for post-extraction complications in patients without antibiotic prophylaxis stratified by early- and late-complications and complication type (oral infection and dry socket). METHODS: Retrospective, case (with complications)-control (without complications) study of patients (n = 708) who had ≥1 extraction performed at any Veterans Health Administration facility between 2015-2019 and were not prescribed an antibiotic 30 days pre-extraction. RESULTS: Early complication cases (n = 109) were more likely to be female [odds ratio (OR) = 2.06; 95% confidence interval (CI):1.05-4.01], younger (OR = 0.29; 95% CI:0.09-0.94 patients ≥ 80 years old, reference:18-44 years), Native American/Alaska Native (OR = 21.11; 95% CI:2.33-191.41) and have fewer teeth extracted (OR = 0.53 3+ teeth extracted; 95% CI:0.31-0.88, reference:1 tooth extracted). Late complication cases (n = 67) were more likely to have a bipolar diagnosis (OR = 2.98; 95% CI:1.04-8.57), history of implant placement (OR = 8.27; 95% CI:1.63-41.82), and history of past smoking (OR = 2.23; 95% CI:1.28-3.88). CONCLUSION: Predictors for post-extraction complications among patients who did not receive antibiotic prophylaxis were similar to prior work in cohorts who received prophylaxis. Unique factors identified in a medically complex population included being younger, Native American/Alaska Native, having mental health conditions, history of a dental implant, and fewer teeth extracted.

Guideline concordance and antibiotic-associated adverse events between Veterans administration and non-Veterans administration dental settings: a retrospective cohort study.

Background: Antibiotics prescribed as infection prophylaxis prior to dental procedures have the potential for serious adverse drug events (ADEs). However, the extent to which guideline concordance and different dental settings are associated with ADEs from antibiotic prophylaxis is unknown. Aim: The purpose was to assess guideline concordance and antibiotic-associated ADEs and whether it differs by VA and non-VA settings. Methods: Retrospective cohort study of antibiotic prophylaxis prescribed to adults with cardiac conditions or prosthetic joints from 2015 to 2017. Multivariable logistic regression models were fit to assess the impact of ADEs, guideline concordance and dental setting. An interaction term of concordance and dental setting evaluated whether the relationship between ADEs and concordance differed by setting. Results: From 2015 to 2017, 61,124 patients with antibiotic prophylaxis were identified with 62 (0.1%) having an ADE. Of those with guideline concordance, 18 (0.09%) had an ADE while 44 (0.1%) of those with a discordant antibiotic had an ADE (unadjusted OR: 0.84, 95% CI: 0.49-1.45). Adjusted analyses showed that guideline concordance was not associated with ADEs (OR: 0.78, 95% CI: 0.25-2.46), and this relationship did not differ by dental setting (Wald χ^2 p-value for interaction = 0.601). Conclusion: Antibiotic-associated ADEs did not differ by setting or guideline concordance.

Management of Asymptomatic Bacteriuria and Urinary Tract Infections in Patients With Neurogenic Bladder and Factors Associated With Inappropriate Diagnosis and Treatment.

OBJECTIVE: Inappropriate diagnosis and treatment of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) are leading causes of antibiotic overuse but have not been well-studied in patients with risks for complicated UTI such as neurogenic bladder (NB). Our aim was to describe ASB and UTI management in patients with NB and assess factors associated with inappropriate management. DESIGN: Retrospective cohort study. SETTING: Four Department of Veteran's Affairs (VA) medical centers. PARTICIPANTS: Adults with NB due to spinal cord injury/disorder (SCI/D), multiple sclerosis (MS), or Parkinson disease (PD) and encounters with an ASB or UTI diagnosis between 2017 and 2018. Clinical and encounter data were extracted from the VA Corporate Data Warehouse and medical record reviews for a stratified sample of 300 encounters from N=291 patients. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Prevalence of appropriate and inappropriate ASB and UTI diagnosis and treatment was summarized. Multivariable logistic regression models assessed factors associated with inappropriate management. RESULTS: N=200 UTI and N=100 ASB encounters were included for the 291 unique patients (SCI/D, 39.9%; MS, 36.4%; PD, 23.7%). Most patients were men (83.3%), >65 years (62%), and used indwelling or intermittent catheterization (68.3%). Nearly all ASB encounters had appropriate diagnosis (98%). 70 (35%) UTI encounters had inappropriate diagnosis, including 55 (27.5%) with true ASB, all with inappropriate treatment. Among the remaining 145 UTI encounters, 54 (27%) had inappropriate treatment. Peripheral vascular disease, chronic kidney disease, and cerebrovascular disease were associated with increased odds of inappropriate management; indwelling catheter (aOR 0.35, P=.01) and Physical Medicine & Rehabilitation provider (aOR 0.29, P<.01) were associated with decreased odds. CONCLUSION: Up to half of UTI encounters for patients with NB had inappropriate management, largely due to inappropriate UTI diagnosis in patients with true ASB. Interventions to improve ASB and UTI management in patients with NB should target complex patients with comorbidities being seen by non-rehabilitation providers.

The association of burnout with work absenteeism and the frequency of thoughts in leaving their job in a cohort of healthcare workers during the COVID-19 pandemic.

Introduction: During the coronavirus disease 2019 pandemic, high levels of burnout were reported among healthcare workers. This study examines the association of work absenteeism and frequency of thoughts in leaving current job with burnout among a cohort of healthcare workers during the COVID-19 pandemic. Methods: A cross-sectional survey of healthcare workers was conducted from April-May, 2022 on healthcare workers from 10 hospitals, 18 immediate care centers, and 325 outpatient practices in the Chicago area and surrounding Illinois suburbs. Logistic regression models were used to assess the association of burnout scores (Oldenburg Burnout Inventory-OLBI) and its sub-scores (exhaustion and disengagement scores) with work absenteeism and thoughts of leaving work. Results: One-fifth and 60% of respondents (n = 1,825) reported unplanned absenteeism and thoughts of leaving their job, respectively. After adjusting for covariates, higher burnout scores, especially exhaustion scores, were associated with increased odds of unplanned absenteeism (OR = 1.04, 95% CI: 1.01-1.08). Burnout scores and both sub-scores were also positively associated with the frequency of thoughts of leaving work, e.g., each unit increase in the OLBI burnout score was associated with 1.39 (95% CI: 1.34-1.43) times higher odds of thinking about leaving work "a lot/constantly" vs. "never". Discussion: Overall, this study cohort showed a positive association between burnout scores and unplanned work absenteeism (and frequency of thoughts in leaving job) during the COVID-19 pandemic. More research is needed to support healthcare worker well-being during times of stress and direct solutions to addressing unplanned absenteeism in the light of a pandemic.

Treatment effectiveness of antibiotic therapy in Veterans with multidrug-resistant Acinetobacter spp. bacteremia.

Objective: To describe antimicrobial therapy used for multidrug-resistant (MDR) Acinetobacter spp. bacteremia in Veterans and impacts on mortality. Methods: This was a retrospective cohort study of hospitalized Veterans Affairs patients from 2012 to 2018 with a positive MDR Acinetobacter spp. blood culture who received antimicrobial treatment 2 days prior to through 5 days after the culture date. Only the first culture per patient was used. The association between treatment and patient characteristics was assessed using bivariate analyses. Multivariable logistic regression models examined the relationship between antibiotic regimen and in-hospital, 30-day, and 1-year mortality. Generalized linear models were used to assess cost outcomes. Results: MDR Acinetobacter spp. was identified in 184 patients. Most cultures identified were Acinetobacter baumannii (90%), 3% were Acinetobacter lwoffii, and 7% were other Acinetobacter species. Penicillins-ß-lactamase inhibitor combinations (51.1%) and carbapenems (51.6%)-were the most prescribed antibiotics. In unadjusted analysis, extended spectrum cephalosporins and penicillins-ß-lactamase inhibitor combinations-were associated with a decreased odds of 30-day mortality but were insignificant after adjustment (adjusted odds ratio (aOR) = 0.47, 95% CI, 0.21-1.05, aOR = 0.75, 95% CI, 0.37-1.53). There was no association between combination therapy vs monotherapy and 30-day mortality (aOR = 1.55, 95% CI, 0.72-3.32). Conclusion: In hospitalized Veterans with MDR Acinetobacter spp., none of the treatments were shown to be associated with in-hospital, 30-day, and 1-year mortality. Combination therapy was not associated with decreased mortality for MDR Acinetobacter spp. bacteremia.
