Background: Inappropriate diagnosis of infections results in antibiotic overuse and may delay diagnosis of underlying conditions. Here we describe the development and characteristics of 2 safety measures of inappropriate diagnosis of urinary tract infection (UTI) and community-acquired pneumonia (CAP), the most common inpatient infections on general medicine services., Methods: Measures were developed from guidelines and literature and adapted based on data from patients hospitalized with UTI and CAP in 49 Michigan hospitals and feedback from end-users, a technical expert panel (TEP), and a patient focus group. Each measure was assessed for reliability, validity, feasibility, and usability., Results: Two measures, now endorsed by the National Quality Forum (NQF), were developed. Measure reliability (derived from 24 483 patients) was excellent (0.90 for UTI; 0.91 for CAP). Both measures had strong validity demonstrated through (a) face validity by hospital users, the TEPs, and patient focus group, (b) implicit case review (ĸ 0.72 for UTI; ĸ 0.72 for CAP), and (c) rare case misclassification (4% for UTI; 0% for CAP) due to data errors (<2% for UTI; 6.3% for CAP). Measure implementation through hospital peer comparison in Michigan hospitals (2017 to 2020) demonstrated significant decreases in inappropriate diagnosis of UTI and CAP (37% and 32%, respectively, P < .001), supporting usability., Conclusions: We developed highly reliable, valid, and usable measures of inappropriate diagnosis of UTI and CAP for hospitalized patients. Hospitals seeking to improve diagnostic safety, antibiotic use, and patient care should consider using these measures to reduce inappropriate diagnosis of CAP and UTI., Competing Interests: Potential conflicts of interest.

Objective: To examine impacts of a structured mentorship committee program on academic promotion and participant perceptions because impacts of formal mentorship programs for clinical faculty are unknown., Participants and Methods: This prospective cohort study at a Midwestern Veterans Affairs tertiary care system from December 17, 2019 to December 31, 2022 included clinical track faculty in the Medicine Service below the rank of Clinical Associate Professor. Mentoring meetings (mentee, committee chair, and mentors) were generally held twice annually. All participants were surveyed after each meeting (response rate: 100%)., Results: All 23 of 23 (100%) eligible faculty were enrolled as mentees, and 49 distinct meetings occurred. Three (13%) mentees were promoted, and the remaining 20 (87%) continued in the program. Mean scores (SD), scaled 1 (strongly disagree) to 5 (strongly agree), for mentors and mentees were 4.71 (0.51) and 4.80 (0.54) for "effective use of my time"; 4.58 (0.64) and 4.37 (0.49) for "appropriate progress since last meeting"; 4.52 (0.66) and 4.31 (0.64) for "program increased my work satisfaction"; and 4.07 (0.96) and 3.75 (0.92) for "program reduced my work burnout," respectively., Conclusion: Clinically oriented physicians viewed the program positively. It appeared to help junior faculty get promoted and led to improved work satisfaction and reduced burnout., Competing Interests: The authors report no competing interests.

Importance: Little is known about incidence of, risk factors for, and harms associated with inappropriate diagnosis of community-acquired pneumonia (CAP)., Objective: To characterize inappropriate diagnosis of CAP in hospitalized patients., Design, Setting, and Participants: This prospective cohort study, including medical record review and patient telephone calls, took place across 48 Michigan hospitals. Trained abstractors retrospectively assessed hospitalized patients treated for CAP between July 1, 2017, and March 31, 2020. Patients were eligible for inclusion if they were adults admitted to general care with a discharge diagnostic code of pneumonia who received antibiotics on day 1 or 2 of hospitalization. Data were analyzed from February to December 2023., Main Outcomes and Measures: Inappropriate diagnosis of CAP was defined using a National Quality Forum-endorsed metric as CAP-directed antibiotic therapy in patients with fewer than 2 signs or symptoms of CAP or negative chest imaging. Risk factors for inappropriate diagnosis were assessed and, for those inappropriately diagnosed, 30-day composite outcomes (mortality, readmission, emergency department visit, Clostridioides difficile infection, and antibiotic-associated adverse events) were documented and stratified by full course (>3 days) vs brief (≤3 days) antibiotic treatment using generalized estimating equation models adjusting for confounders and propensity for treatment., Results: Of the 17 290 hospitalized patients treated for CAP, 2079 (12.0%) met criteria for inappropriate diagnosis (median [IQR] age, 71.8 [60.1-82.8] years; 1045 [50.3%] female), of whom 1821 (87.6%) received full antibiotic courses. Compared with patients with CAP, patients inappropriately diagnosed were older (adjusted odds ratio [AOR], 1.08; 95% CI, 1.05-1.11 per decade) and more likely to have dementia (AOR, 1.79; 95% CI, 1.55-2.08) or altered mental status on presentation (AOR, 1.75; 95% CI, 1.39-2.19). Among those inappropriately diagnosed, 30-day composite outcomes for full vs brief treatment did not differ (25.8% vs 25.6%; AOR, 0.98; 95% CI, 0.79-1.23). Full vs brief duration of antibiotic treatment among patients was associated with antibiotic-associated adverse events (31 of 1821 [2.1%] vs 1 of 258 [0.4%]; P = .03)., Conclusions and Relevance: In this cohort study, inappropriate diagnosis of CAP among hospitalized adults was common, particularly among older adults, those with dementia, and those presenting with altered mental status. Full-course antibiotic treatment of those inappropriately diagnosed with CAP may be harmful.

Importance: Guidelines recommend withholding antibiotics in asymptomatic bacteriuria (ASB), including among patients with altered mental status (AMS) and no systemic signs of infection. However, ASB treatment remains common., Objectives: To determine prevalence and factors associated with bacteremia from a presumed urinary source in inpatients with ASB with or without AMS and estimate antibiotics avoided if a 2% risk of bacteremia were used as a threshold to prompt empiric antibiotic treatment of ASB., Design, Setting, and Participants: This cohort study assessed patients hospitalized to nonintensive care with ASB (no immune compromise or concomitant infections) in 68 Michigan hospitals from July 1, 2017, to June 30, 2022. Data were analyzed from August 2022 to January 2023., Main Outcomes and Measures: The primary outcome was prevalence of bacteremia from a presumed urinary source (ie, positive blood culture with matching organisms within 3 days of urine culture). To determine factors associated with bacteremia, we used multivariable logistic regression models. We estimated each patient's risk of bacteremia and determined what percentage of patients empirically treated with antibiotics had less than 2% estimated risk of bacteremia., Results: Of 11 590 hospitalized patients with ASB (median [IQR] age, 78.2 [67.7-86.6] years; 8595 female patients [74.2%]; 2235 African American or Black patients [19.3%], 184 Hispanic patients [1.6%], and 8897 White patients [76.8%]), 8364 (72.2%) received antimicrobial treatment for UTI, and 161 (1.4%) had bacteremia from a presumed urinary source. Only 17 of 2126 patients with AMS but no systemic signs of infection (0.7%) developed bacteremia. On multivariable analysis, male sex (adjusted odds ratio [aOR], 1.45; 95% CI, 1.02-2.05), hypotension (aOR, 1.86; 95% CI, 1.18-2.93), 2 or more systemic inflammatory response criteria (aOR, 1.72; 95% CI, 1.21-2.46), urinary retention (aOR, 1.87; 95% CI, 1.18-2.96), fatigue (aOR, 1.53; 95% CI, 1.08-2.17), log of serum leukocytosis (aOR, 3.38; 95% CI, 2.48-4.61), and pyuria (aOR, 3.31; 95% CI, 2.10-5.21) were associated with bacteremia. No single factor was associated with more than 2% risk of bacteremia. If 2% or higher risk of bacteremia were used as a cutoff for empiric antibiotics, antibiotic exposure would have been avoided in 78.4% (6323 of 8064) of empirically treated patients with low risk of bacteremia., Conclusions and Relevance: In patients with ASB, bacteremia from a presumed urinary source was rare, occurring in less than 1% of patients with AMS. A personalized, risk-based approach to empiric therapy could decrease unnecessary ASB treatment.

Objective: To explore infection preventionists' perceptions of hospital leadership support for infection prevention and control programs during the coronavirus disease 2019 (COVID-19) pandemic and relationships with individual perceptions of burnout, psychological safety, and safety climate., Design: Cross-sectional survey, administered April through December 2021., Setting: Random sample of non-federal acute-care hospitals in the United States., Participants: Lead infection preventionists., Results: We received responses from 415 of 881 infection preventionists, representing a response rate of 47%. Among respondents, 64% reported very good to excellent hospital leadership support for their infection prevention and control program. However, 49% reported feeling burned out from their work. Also, ∼30% responded positively for all 7 psychological safety questions and were deemed to have "high psychological safety," and 76% responded positively to the 2 safety climate questions and were deemed to have a "high safety climate." Our results indicate an association between strong hospital leadership support and lower burnout (IRR, 0.61; 95% CI, 0.50-0.74), higher perceptions of psychological safety (IRR, 3.20; 95% CI, 2.00-5.10), and a corresponding 1.2 increase in safety climate on an ascending Likert scale from 1 to 10 (β, 1.21; 95% CI, 0.93-1.49)., Conclusions: Our national survey provides evidence that hospital leadership support may have helped infection preventionists avoid burnout and increase perceptions of psychological safety and safety climate during the COVID-19 pandemic. These findings aid in identifying factors that promote the well-being of infection preventionists and enhance the quality and safety of patient care.

Background: Antimicrobial stewardship in Thailand has made major progress backed by a national strategic plan. The current study aimed to assess the antimicrobial stewardship program (ASP) composition, reach, and breadth, as well as urine culture stewardship in Thai hospitals., Methods: We sent an electronic survey to 100 Thai hospitals between February 1, 2021 and August 31, 2021. This hospital sample represented 20 hospitals in each of Thailand's 5 geographical regions., Results: The response rate was 100%. A total of 86 of 100 hospitals had an ASP. These were often multi-disciplinary in nature, with half including infectious disease-trained physicians and pharmacists, infection preventionists, and nursing staff. Urine culture stewardship protocols existed in 51% of hospitals., Conclusions: The national strategic plan in Thailand has allowed the country to stand up robust ASPs. Further research should examine the effectiveness of such programs and ways to expand them into other medical settings, like nursing homes, urgent care, and outpatient while continuing to grow telehealth and urine culture stewardship., (Copyright © 2023 Association for Professionals in Infection Control and Epidemiology, Inc.

In a cross-sectional survey of US acute care hospitals, antimicrobial stewardship programs were present in most Veterans Affairs and nonfederal hospitals but varied in team composition, scope, and impact. Diagnostic stewardship was common across hospitals. Veterans Affairs hospitals had increased reach in outpatient settings.

Objective: The ways that device-associated infection prevention practices changed during the coronavirus disease 2019 (COVID-19) pandemic remain unknown. We collected data mid-pandemic to assess the use of several infection prevention practices and for comparison with historical data., Design: Repeated cross-sectional survey., Setting: US acute-care hospitals., Participants: Infection preventionists., Methods: We surveyed infection preventionists from a national random sample of 881 US acute-care hospitals in 2021 to estimate the current use of practices to prevent catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), and ventilator-associated events (VAE). We compared the 2021 results with those from surveys occurring every 4 years since 2005., Results: The 2021 survey response rate was 47%; previous survey response rates ranged from 59% to 72%. Regular use of most practices to prevent CLABSI (chlorhexidine gluconate for site antisepsis, 99.0%, and maximum sterile barrier precautions, 98.7%) and VAE (semirecumbent positioning, 93.4%, and sedation vacation, 85.8%) continued to increase or plateaued in 2021. Conversely, use of several CAUTI prevention practices (portable bladder ultrasound scanner, 65.6%; catheter reminders or nurse-initiated discontinuation, 66.3%; and intermittent catheterization, 37.3%) was lower in 2021, with a significant decrease for some practices compared to 2017 (P ≤ .02 for all comparisons). In 2021, 42.1% of hospitals reported regular use of the newer external urinary collection devices for women., Conclusions: Although regular use of CLABSI and VAE preventive practices continued to increase (or plateaued), use of several CAUTI preventive practices decreased during the COVID-19 pandemic. Structural issues relating to care during the pandemic may have contributed to a decrease in device-associated infection prevention practices.

Importance: Hospitalized patients with asymptomatic bacteriuria (ASB) often receive unnecessary antibiotic treatment, which increases antibiotic resistance and adverse events., Objective: To determine whether diagnostic stewardship (avoiding unnecessary urine cultures) or antibiotic stewardship (reducing unnecessary antibiotic treatment after an unnecessary culture) is associated with better outcomes in reducing antibiotic use for ASB., Design, Setting, and Participants: This 3-year, prospective quality improvement study included hospitalized general care medicine patients with a positive urine culture among 46 hospitals participating in a collaborative quality initiative, the Michigan Hospital Medicine Safety Consortium. Data were collected from July 1, 2017, through March 31, 2020, and analyzed from February to October 2022., Exposure: Participation in the Michigan Hospital Medicine Safety Consortium with antibiotic and diagnostic stewardship strategies at hospital discretion., Main Outcomes and Measures: Overall improvement in ASB-related antibiotic use was estimated as change in percentage of patients treated with antibiotics who had ASB. Effect of diagnostic stewardship was estimated as change in percentage of patients with a positive urine culture who had ASB. Effect of antibiotic stewardship was estimated as change in percentage of patients with ASB who received antibiotics and antibiotic duration., Results: Of the 14 572 patients with a positive urine culture included in the study (median [IQR] age, 75.8 [64.2-85.1] years; 70.5% female); 28.4% (n = 4134) had ASB, of whom 76.8% (n = 3175) received antibiotics. Over the study period, the percentage of patients treated with antibiotics who had ASB (overall ASB-related antibiotic use) declined from 29.1% (95% CI, 26.2%-32.2%) to 17.1% (95% CI, 14.3%-20.2%) (adjusted odds ratio [aOR], 0.94 per quarter; 95% CI, 0.92-0.96). The percentage of patients with a positive urine culture who had ASB (diagnostic stewardship metric) declined from 34.1% (95% CI, 31.0%-37.3%) to 22.5% (95% CI, 19.7%-25.6%) (aOR, 0.95 per quarter; 95% CI, 0.93-0.97). The percentage of patients with ASB who received antibiotics (antibiotic stewardship metric) remained stable, from 82.0% (95% CI, 77.7%-85.6%) to 76.3% (95% CI, 68.5%-82.6%) (aOR, 0.97 per quarter; 95% CI, 0.94-1.01), as did adjusted mean antibiotic duration, from 6.38 (95% CI, 6.00-6.78) days to 5.93 (95% CI, 5.54-6.35) days (adjusted incidence rate ratio, 0.99 per quarter; 95% CI, 0.99-1.00)., Conclusions and Relevance: This quality improvement study showed that over 3 years, ASB-related antibiotic use decreased and was associated with a decline in unnecessary urine cultures. Hospitals should prioritize reducing unnecessary urine cultures (ie, diagnostic stewardship) to reduce antibiotic treatment related to ASB.

Background: Due to their high biodiversity, small water bodies play an important role for freshwater ecosystems. Nonetheless, systematic pesticide monitoring in small creeks with a catchment <30 km 2 is rarely conducted., Methods: In this study, event-driven water samples were taken from May until November 2017 and March until July 2018 after 20 rain events at three sampling sites with catchment areas of <27 km 2 in the Wetterau, a region with intensive agriculture in Southern Hesse, Germany. Additionally, enriched extracts of the native water samples from the campaign in 2018 were used for the Microtox assay to determine baseline toxicity to invertebrates over time and sum of toxic units (STU) were calculated to compare the potential toxicity of the samples., Results: Overall, 37 pesticides and 17 transformation products were found, whereby the herbicide metamitron (79 µg/L) showed the highest concentration. Regularly, pesticide concentrations peaked at the time of the highest water level within each sampling event. Within each sampling event maximum pesticide concentration was mostly reached in water samples taken during the first two hours. The sum of the time-weighted mean concentration values of all pesticides was between 2.0 µg/L and 7.2 µg/L, whereby the measured concentrations exceeded their regulatory acceptable concentration (RAC) at 55% of all sampling events for at least one pesticide. The mean EC 50 values varied between 28.6 ± 13.1 to 41.3 ± 12.1 REF (relative enrichment factor). The results indicated that several samples caused baseline toxicity, whereby the highest activity was measured at the time of highest water levels and pesticides concentrations, and then steadily decreased in parallel with the water level. Median STUs of invertebrates ranged from -2.10 to -3.91, of algae/aquatic plants from -0.79 to -1.84 and of fish from -2.47 to -4.24. For one of the three sampling sites, a significant linear correlation between baseline toxicity and STU invertebrate was found ( r 2  = 0.48)., Conclusion: The results of the present study suggest that (1) current pesticide monitoring programs underestimate risks posed by the exposure to pesticides for aquatic organisms and (2) pre-authorization regulatory risk assessment schemes are insufficient to protect aquatic environments., Competing Interests: Jörg Oehlmann is an Academic Editor for PeerJ.

Background: Quality improvement and patient safety (QIPS) curricula are critical in graduate medical education, yet barriers limit the educational experience and project outcomes., Objective: To explore the impact of QIPS curricular enhancements and integration of continuous improvement specialists (CIS) by examining the A3 document, the primary project product and surrogate for project quality., Methods: Since 2009, University of Michigan internal medicine and medicine-pediatric residents participate in a QIPS curriculum, which includes a 4-week group project. In 2016, residency leaders collaborated with CIS staff, non-clinical experts in QIPS with backgrounds in engineering and business, to improve the curriculum. Informed by a needs assessment, the intervention was implemented in 2017 and consisted of a set of enhancements including integration of CIS staff into groups as co-facilitators. In this retrospective cohort study, a blinded reviewer evaluated all available A3 documents before and after the intervention using a quantitative analysis tool., Results: All residents participated in the curriculum during the pre-intervention (July 2009 to June 2016, n=351) and post-intervention (July 2017 to June 2020, n=148) periods. A total of 23 of 84 (27%) pre-intervention and 31 of 34 (91%) post-intervention A3 documents were available for review. Scores improved significantly for 17 of 23 (74%) A3 items and for 7 of 8 (88%) sections. Mean A3 total scores increased from 29.0 to 47.0 (95% CI 12.6-23.4; P <.001) out of a possible 69.0., Conclusions: Embedding CIS experts into residency QIPS curricula is associated with improved A3 document quality., Competing Interests: Conflict of interest: The authors declare they have no competing interests., (© 2023.)

Background: Oral case presentations - structured verbal reports of clinical cases - are fundamental to patient care and learner education. Despite their continued importance in a modernized medical landscape, their structure has remained largely unchanged since the 1960s, based on the traditional Subjective, Objective, Assessment, Plan (SOAP) format developed for medical records. We developed a problem-based alternative known as Events, Assessment, Plan (EAP) to understand the perceived efficacy of EAP compared to SOAP among learners., Methods: We surveyed (Qualtrics, via email) all third- and fourth-year medical students and internal medicine residents at a large, academic, tertiary care hospital and associated Veterans Affairs medical center. The primary outcome was trainee preference in oral case presentation format. The secondary outcome was comparing EAP and SOAP on 10 functionality domains assessed via a 5-point Likert scale. We used descriptive statistics (proportion and mean) to describe the results., Results: The response rate was 21% (118/563). Of the 59 respondents with exposure to both the EAP and SOAP formats, 69% (n = 41) preferred the EAP format as compared to 19% (n = 11) who preferred SOAP (p < 0.001). EAP outperformed SOAP in 8 out of 10 of the domains assessed, including advancing patient care, learning from patients, and time efficiency., Conclusions: Our findings suggest that trainees prefer the EAP format over SOAP and that EAP may facilitate clearer and more efficient communication on rounds, which in turn may enhance patient care and learner education. A broader, multi-center study of the EAP oral case presentation will help to better understand preferences, outcomes, and barriers to implementation., (© 2023.

Background: Definitions of malnutrition imperfectly reflect nutritional status or predict perioperative consequences. We sought to identify predictive nutritional trends by examining the effect of preoperative weight on postoperative outcomes in patients with colorectal cancer (CRC)., Methods: This retrospective review examined 148 patients with CRC treated with curative-intent surgery at the Veterans Affairs Ann Arbor Healthcare System in Michigan from January 1, 2015 to December 31, 2019. We evaluated weight dynamics of patients, starting 1 year before cancer diagnosis until 1 year after surgery. We evaluated the association of these weight dynamics with surgical outcomes. Primary outcomes observed were hospital readmission and length of stay (LOS), chemotherapy completion, and delayed recovery defined as abnormal clinical developments., Results: There were 115 patients in the colon cancer (CC) cohort and 33 in the rectal cancer (RC) cohort. Low preoperative albumin (< 3.5 g/dL) was present in 25 patients with CC (22%) and 11 patients with RC (33%). Six-month preoperative weight loss of at least 3% occurred in 32 patients with CC (36%). Delayed recovery was observed in 35 patients with CC (30%) and 21 patients with RC (64%). Nutrition consultation rates for the CC and RC groups were 15% and 36%, respectively, before the operation; 95% and 100%, respectively, for postoperative inpatients; and 12% and 73%, respectively, for postoperative outpatients. Six-month preoperative weight loss of ≥ 3% was significantly associated with delayed recovery ( P < .001) and 60-day readmissions ( P = .015) but not increased LOS or chemotherapy noncompletion., Conclusions: A ≥ 3% weight loss 6 months preceding curative surgery for CRC was associated with adverse outcomes. An intensive nutrition prehabilitation program initiated at the time of cancer diagnosis is needed and may reduce associated complications., Competing Interests: Author disclosures The authors report no actual or potential conflicts of interest or outside sources of funding with regard to this article., (Copyright © 2023 Frontline Medical Communications Inc., Parsippany, NJ, USA.)

Background: As the COVID-19 pandemic evolves, it is critical to understand characteristics that have allowed US healthcare systems, including the Veterans Affairs (VA) and non-federal hospitals, to mount an effective response in the setting of limited resources and unpredictable clinical demands generated by this system shock., Objective: To compare the impact of and response to resource shortages to both VA and non-federal healthcare systems during the COVID-19 pandemic., Design: Cross-sectional national survey administered April 2021 through May 2022., Participants: Lead infection preventionists from VA and non-federal hospitals across the US., Main Measures: Surveys collected hospital demographic factors along with 11 questions aimed at assessing the effectiveness of the hospital's COVID response., Key Results: The response rate was 56% (71/127) from VA and 47% (415/881) from non-federal hospitals. Compared to VA hospitals, non-federal hospitals had a larger average number of acute care (214 vs. 103 beds, p<.001) and intensive care unit (24 vs. 16, p<.001) beds. VA hospitals were more likely to report no shortages of personal protective equipment or medical supplies during the pandemic (17% vs. 9%, p=.03) and more frequently opened new units to care specifically for COVID patients (71% vs. 49%, p<.001) compared with non-federal hospitals. Non-federal hospitals more frequently experienced increased loss of staff due to resignations (76% vs. 53%, p=.001) and financial hardships stemming from the pandemic (58% vs. 7%, p<0.001)., Conclusions: In our survey-based national study, lead infection preventionists noted several distinct advantages in VA versus non-federal hospitals in their ability to expand bed capacity, retain staff, mitigate supply shortages, and avoid financial hardship. While these benefits appear to be inherent to the VA's structure, non-federal hospitals can adapt their infrastructure to better weather future system shocks., (© 2022.

Background A recent randomized trial, the MICHELLE trial, demonstrated improved posthospital outcomes with a 35-day course of prophylactic rivaroxaban for patients hospitalized with COVID-19 at high risk of venous thromboembolism. We explored how often these findings may apply to an unselected clinical population of patients hospitalized with COVID-19. Methods and Results Using a 35-hospital retrospective cohort of patients hospitalized between March 7, 2020, and January 23, 2021, with COVID-19 (MI-COVID19 database), we quantified the percentage of hospitalized patients with COVID-19 who would be eligible for rivaroxaban at discharge per MICHELLE trial criteria and report clinical event rates. The main clinical outcome was derived from the MICHELLE trial and included a composite of symptomatic venous thromboembolism, pulmonary embolus-related death, nonhemorrhagic stroke, and cardiovascular death at 35 days. Multiple sensitivity analyses tested different eligibility and exclusion criteria definitions to determine the effect on eligibility for postdischarge anticoagulation prophylaxis. Of 2016 patients hospitalized with COVID-19 who survived to discharge and did not have another indication for anticoagulation, 25.9% (n=523) would be eligible for postdischarge thromboprophylaxis per the MICHELLE trial criteria (range, 2.9%-39.4% on sensitivity analysis). Of the 416 who had discharge anticoagulant data collected, only 13.2% (55/416) were actually prescribed a new anticoagulant at discharge. Of patients eligible for rivaroxaban per the MICHELLE trial, the composite clinical outcome occurred in 1.2% (6/519); similar outcome rates were 5.7% and 0.63% in the MICHELLE trial's control (no anticoagulation) and intervention (rivaroxaban) groups, respectively. Symptomatic venous thromboembolism events and all-cause mortality were 6.2% (32/519) and 5.66% in the MI-COVID19 and MICHELLE trial control cohorts, respectively. Conclusions Across 35 hospitals in Michigan, ≈1 in 4 patients hospitalized with COVID-19 would qualify for posthospital thromboprophylaxis. With only 13% of patients actually receiving postdischarge prophylaxis, there is a potential opportunity for improvement in care.

Objective: The patient-physician relationship impacts patients' experiences and health outcomes. Physician attire is a form of nonverbal communication that influences this relationship. Prior studies examining attire preferences suffered from heterogeneous measurement and limited context. We thus performed a multicentre, cross-sectional study using a standardised survey instrument to compare patient preferences for physician dress in international settings., Setting: 20 hospitals and healthcare practices in Italy, Japan, Switzerland and the USA., Participants: Convenience sample of 9171 adult patients receiving care in academic hospitals, general medicine clinics, specialty clinics and ophthalmology practices., Primary and Secondary Outcome Measures: The survey was randomised and included photographs of a male or female physician dressed in assorted forms of attire. The primary outcome measure was attire preference, comprised of composite ratings across five domains: how knowledgeable, trustworthy, caring and approachable the physician appeared, and how comfortable the respondent felt. Secondary outcome measures included variation in preferences by country, physician type and respondent characteristics., Results: The highest rated forms of attire differed by country, although each most preferred attire with white coat. Low ratings were conferred on attire extremes (casual and business suit). Preferences were more uniform for certain physician types. For example, among all respondents, scrubs garnered the highest rating for emergency department physicians (44.2%) and surgeons (42.4%). However, attire preferences diverged for primary care and hospital physicians. All types of formal attire were more strongly preferred in the USA than elsewhere. Respondent age influenced preferences in Japan and the USA only., Conclusions: Patients across a myriad of geographies, settings and demographics harbour specific preferences for physician attire. Some preferences are nearly universal, whereas others vary substantially. As a one-size-fits-all dress policy is unlikely to reflect patient desires and expectations, a tailored approach should be sought that attempts to match attire to clinical context., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: Strategies to optimize antibiotic prescribing at discharge are not well understood., Methods: In fall 2019, we surveyed 39 Michigan hospitals on their antibiotic stewardship strategies. The association of reported strategies with discharge antibiotic overuse (unnecessary, excess, suboptimal fluoroquinolones) for community-acquired pneumonia (CAP) and urinary tract infection (UTI) was evaluated in 2 ways: (1) all strategies assumed equal weight and (2) strategies were weighted based on the ROAD (Reducing Overuse of Antibiotics at Discharge) Home Framework (ie, Tier 1-Critical infrastructure, Tier 2-Broad inpatient interventions, Tier 3-Discharge-specific strategies) with Tier 3 strategies receiving the highest weight., Results: Between 1 July 2017 and 30 July 2019, 39 hospitals with 20 444 patients (56.5% CAP; 43.5% UTI) were included. Survey response was 100%. Hospitals reported a median (interquartile range [IQR]) 12 (9-14) of 34 possible stewardship strategies. On analyses of individual stewardship strategies, the Tier 3 intervention, review of antibiotics prior to discharge, was the only strategy consistently associated with lower antibiotic overuse at discharge (adjusted incident rate ratio [aIRR] 0.543, 95% confidence interval [CI]: .335-.878). On multivariable analysis, weighting by ROAD Home tier predicted antibiotic overuse at discharge for both CAP and UTI. For diseases combined, having more weighted strategies was associated with lower antibiotic overuse at discharge (aIRR 0.957, 95% CI: .927-.987, per weighted intervention); discharge-specific stewardship strategies were associated with a 12.4% relative decrease in antibiotic overuse days at discharge., Conclusions: The more stewardship strategies a hospital reported, the lower its antibiotic overuse at discharge. However, Tier 3, or discharge-specific strategies, appeared to have the largest effect on antibiotic prescribing at discharge., Competing Interests: Potential conflicts of interest. S.

Background: Healthcare-associated infection (HAI) is a common and largely preventable cause of morbidity and mortality. The COVID-19 pandemic has presented unprecedented challenges to health systems. We conducted a national survey to ascertain hospital characteristics and the use of HAI prevention measures in Israel., Methods: We e-mailed surveys to infection prevention and control (IPC) leads of acute care hospitals in Israel. The survey included questions about the use of practices to prevent catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), and Clostridioides difficile infection (CDI). The survey also assessed COVID-19 impact and healthcare worker well-being., Results: IPC leads from 15 of 24 invited hospitals (63%) completed the survey. Only one-third of respondents reported strong support for IPC from hospital leadership. Although several prevention practices were used by all hospitals (e.g., maximum sterile barrier precautions for CLABSI and real-time assessment of environmental cleaning for CDI), use of other practices was suboptimal-particularly for CAUTI and VAP. COVID-19 had a profound impact on Israeli hospitals, with all hospitals reporting opening of new units to care for COVID patients and most reporting moderate to extreme financial hardship. All hospitals reported highly successful plans to vaccinate all staff and felt confident that the vaccine is safe and effective., Conclusion: We provide a status report of the IPC characteristics and practices Israeli hospitals are currently using to prevent HAIs during the COVID-19 era. While many globally accepted IPC practices are widely implemented, opportunities to increase the use of certain IPC practices in Israeli hospitals exist., (© 2022. The Author(s).)

Background: We sought to determine the incidence of community-onset and hospital-acquired coinfection in patients hospitalized with coronavirus disease 2019 (COVID-19) and to evaluate associated predictors and outcomes., Methods: In this multicenter retrospective cohort study of patients hospitalized for COVID-19 from March 2020 to August 2020 across 38 Michigan hospitals, we assessed prevalence, predictors, and outcomes of community-onset and hospital-acquired coinfections. In-hospital and 60-day mortality, readmission, discharge to long-term care facility (LTCF), and mechanical ventilation duration were assessed for patients with versus without coinfection., Results: Of 2,205 patients with COVID-19, 141 (6.4%) had a coinfection: 3.0% community onset and 3.4% hospital acquired. Of patients without coinfection, 64.9% received antibiotics. Community-onset coinfection predictors included admission from an LTCF (OR, 3.98; 95% CI, 2.34-6.76; P < .001) and admission to intensive care (OR, 4.34; 95% CI, 2.87-6.55; P < .001). Hospital-acquired coinfection predictors included fever (OR, 2.46; 95% CI, 1.15-5.27; P = .02) and advanced respiratory support (OR, 40.72; 95% CI, 13.49-122.93; P < .001). Patients with (vs without) community-onset coinfection had longer mechanical ventilation (OR, 3.31; 95% CI, 1.67-6.56; P = .001) and higher in-hospital mortality (OR, 1.90; 95% CI, 1.06-3.40; P = .03) and 60-day mortality (OR, 1.86; 95% CI, 1.05-3.29; P = .03). Patients with (vs without) hospital-acquired coinfection had higher discharge to LTCF (OR, 8.48; 95% CI, 3.30-21.76; P < .001), in-hospital mortality (OR, 4.17; 95% CI, 2.37-7.33; P ≤ .001), and 60-day mortality (OR, 3.66; 95% CI, 2.11-6.33; P ≤ .001)., Conclusion: Despite community-onset and hospital-acquired coinfection being uncommon, most patients hospitalized with COVID-19 received antibiotics. Admission from LTCF and to ICU were associated with increased risk of community-onset coinfection. Future studies should prospectively validate predictors of COVID-19 coinfection to facilitate the reduction of antibiotic use.

Background: Community-acquired pneumonia (CAP) is a common cause for hospitalization and antibiotic overuse. We aimed to improve antibiotic duration for CAP across 41 hospitals participating in the Michigan Hospital Medicine Safety Consortium (HMS)., Methods: This prospective collaborative quality initiative included patients hospitalized with uncomplicated CAP who qualified for a 5-day antibiotic duration. Between 23 February 2017 and 5 February 2020, HMS targeted appropriate 5-day antibiotic treatment through benchmarking, sharing best practices, and pay-for-performance incentives. Changes in outcomes, including appropriate receipt of 5 ± 1-day antibiotic treatment and 30-day postdischarge composite adverse events (ie, deaths, readmissions, urgent visits, and antibiotic-associated adverse events), were assessed over time (per 3-month quarter), using logistic regression and controlling for hospital clustering., Results: A total of 41 hospitals and 6553 patients were included. The percentage of patients treated with an appropriate 5 ± 1-day duration increased from 22.1% (predicted probability, 20.9% [95% confidence interval: 17.2%-25.0%]) to 45.9% (predicted probability, 43.9% [36.8%-51.2%]; adjusted odds ratio [aOR] per quarter, 1.10 [1.07-1.14]). Thirty-day composite adverse events occurred in 18.5% of patients (1166 of 6319) and decreased over time (aOR per quarter, 0.98 [95% confidence interval: .96-.99]) owing to a decrease in antibiotic-associated adverse events (aOR per quarter, 0.91 [.87-.95])., Conclusions: Across diverse hospitals, HMS participation was associated with more appropriate use of short-course therapy and fewer adverse events in hospitalized patients with uncomplicated CAP. Establishment of national or regional collaborative quality initiatives with data collection and benchmarking, sharing of best practices, and pay-for-performance incentives may improve antibiotic use and outcomes for patients hospitalized with uncomplicated CAP., Competing Interests: Potential conflicts of interest.

Background: Antibiotic overuse at hospital discharge is common and harmful; however, methods to improve prescribing during care transitions have been understudied. We aimed to pilot a pharmacist-facilitated antibiotic timeout prior to discharge., Methods: From May 2019 to October 2019, we conducted a single-center, controlled pilot study of a pharmacist-facilitated antibiotic timeout prior to discharge. The timeout addressed key elements of stewardship (eg, duration) and was designed and implemented using iterative cycles with rapid feedback. We evaluated implementation outcomes related to feasibility, including usability, adherence, and acceptability, using mixed methods. Pre versus postintervention antibiotic use at discharge in intervention versus control groups was assessed using logistic regression models controlling for patient characteristics., Results: Pharmacists conducted 288 antibiotic timeouts. Timeouts were feasible (mean 2.5 minutes per timeout) and acceptable (85% [40/48] of hospitalists believed timeouts improved prescribing). Pharmacists recommended an antibiotic change in 25% (73/288) of timeouts with 70% (51/73) of recommended changes accepted by hospitalists. Barriers to adherence included unanticipated and weekend discharges. Compared to control services, there were no differences in antibiotic use after discharge during the intervention., Conclusions: A pharmacist-facilitated antibiotic timeout at discharge was feasible and holds promise as a method to improve antibiotic use at discharge., (Copyright © 2021.

Background: Indwelling urinary catheters are commonly used in hospitalized patients, which can lead to the development of urinary catheter complications, including catheter-associated urinary tract infection (CAUTI). Limited reports on the appropriateness of urinary catheter use exist in Japan. This study investigated the prevalence and appropriateness of indwelling urinary catheters, and the incidence of CAUTI in non-intensive care unit (non-ICU) wards in Japanese hospitals., Methods: This prospective observational study was conducted in 7 non-ICU wards from 6 hospitals in Japan from October 2017 to June 2018. At each hospital the study teams evaluated urinary catheter prevalence through in-person bedside evaluation for at least 5 days of each week for 3 months. Catheter associated urinary tract infection (CAUTI) incidence and appropriateness of catheter use was collected via chart review., Results: We assessed 710 catheter-days over 5528 patient-days. The mean prevalence of indwelling urinary catheter use in participating wards was 13% (range: 5% to 19%), while the mean incidence of CAUTI was 9.86 per 1000 catheter-days (range: 0 to 33.90). Approximately 66% of the urinary catheter days assessed had an appropriate indication for use (range: 17% to 81%). A physician's order for catheter placement was present in only 10% of catheterized patients., Conclusion: This multicenter study provides epidemiological information about the appropriate use of urinary catheters in Japanese non-ICU wards. A multimodal intervention may help improve the appropriate use of urinary catheters., (© 2022. The Author(s).)

Objectives: We examined the association between multimorbidity and social participation and whether purpose in life and life satisfaction moderate this relationship., Methods: Participants were 12,825 Health and Retirement Study adults. We used multiple linear regression to examine the association between a cumulative-updated multimorbidity-weighted index (MWI) and social participation., Results: Among adults with average purpose in life or life satisfaction, MWI was associated with lower social participation. For those with above average purpose in life, each 1-point increase in MWI was associated with a 0.11-point (95% confidence interval [CI]: [0.07, 0.14]) better social participation score. Participants with above average life satisfaction experienced a 0.04-point (95% CI: [0.02, 0.07]) better social participation score with each 1-point increase in MWI., Discussion: Multimorbidity was associated with worse social participation, but this was reversed by above average purpose in life and life satisfaction. Interventions that improve well-being should be assessed to enhance social participation among older adults with any degree of multimorbidity.

Background: Antibiotics are commonly prescribed to patients as they leave the hospital. We aimed to create a comprehensive metric to characterize antibiotic overuse after discharge among hospitalized patients treated for pneumonia or urinary tract infection (UTI), and to determine whether overuse varied across hospitals and conditions., Methods: In a retrospective cohort study of hospitalized patients treated for pneumonia or UTI in 46 hospitals between 1 July 2017-30 July 2019, we quantified the proportion of patients discharged with antibiotic overuse, defined as unnecessary antibiotic use, excess antibiotic duration, or suboptimal fluoroquinolone use. Using linear regression, we assessed hospital-level associations between antibiotic overuse after discharge in patients treated for pneumonia versus a UTI., Results: Of 21 825 patients treated for infection (12 445 with pneumonia; 9380 with a UTI), nearly half (49.1%) had antibiotic overuse after discharge (56.9% with pneumonia; 38.7% with a UTI). For pneumonia, 63.1% of overuse days after discharge were due to excess duration; for UTIs, 43.9% were due to treatment of asymptomatic bacteriuria. The percentage of patients discharged with antibiotic overuse varied 5-fold among hospitals (from 15.9% [95% confidence interval, 8.7%-24.6%] to 80.6% [95% confidence interval, 69.4%-88.1%]) and was strongly correlated between conditions (regression coefficient = 0.85; P < .001)., Conclusions: Antibiotic overuse after discharge was common and varied widely between hospitals. Antibiotic overuse after discharge was associated between conditions, suggesting that the prescribing culture, physician behavior, or organizational processes contribute to overprescribing at discharge. Multifaceted efforts focusing on all 3 types of overuse and multiple conditions should be considered to improve antibiotic prescribing at discharge., (© The Author(s) 2020.

We assessed the long-term sustainability of a quality improvement intervention to reduce urethral catheter use at a Veterans Affairs (VA) hospital. During the 8 years after the initial intervention, point-prevalence surveillance showed that urethral catheter use continued to decrease (OR, 0.91; 95% CI, 0.86-0.97; P = .003) and that appropriateness of catheter use remained unchanged.
