Change in economy of ultrasound probe motion among general medicine trainees.

OBJECTIVES: To observe change in economy of 9 ultrasound probe movement metrics among internal medicine trainees during a 5-day training course in cardiac point of care ultrasound (POCUS). METHODS: We used a novel probe tracking device to record nine features of ultrasound probe movement, while trainees and experts optimized ultrasound clips on the same volunteer patients. These features included translational movements, gyroscopic movements (titling, rocking, and rotation), smoothness, total path length, and scanning time. We determined the adjusted difference between each trainee's movements and the mean value of the experts' movements for each patient. We then used a mixed effects model to trend average the adjusted differences between trainees and experts throughout the 5 days of the course. RESULTS: Fifteen trainees were enrolled. Three echocardiographer technicians and the course director served as experts. Across 16 unique patients, 294 ultrasound clips were acquired. For all 9 movements, the adjusted difference between trainees and experts narrowed day-to-day (p value < 0.05), suggesting ongoing improvement during training. By the last day of the course, there were no statistically significant differences between trainees and experts in translational movement, gyroscopic movement, smoothness, or total path length; yet on average trainees took 28 s (95% CI [14.7-40.3] seconds) more to acquire a clip. CONCLUSIONS: We detected improved ultrasound probe motion economy among internal medicine trainees during a 5-day training course in cardiac POCUS using an inexpensive probe tracking device. Objectively quantifying probe motion economy may help assess a trainee's level of proficiency in this skill and individualize their POCUS training.

Hypertension Control During the Coronavirus Disease 2019 Pandemic: A Cohort Study Among US Veterans.

DESIGN: Retrospective cohort study. OBJECTIVE: We sought to examine whether disruptions in follow-up intervals contributed to hypertension control. BACKGROUND: Disruptions in health care were widespread during the coronavirus disease 2019 pandemic. PATIENTS AND METHODS: We identified a cohort of individuals with hypertension in both prepandemic (March 2019-February 2020) and pandemic periods (March 2020-February 2022) in the Veterans Health Administration. First, we calculated follow-up intervals between the last prepandemic and first pandemic blood pressure measurement during a primary care clinic visit, and between measurements in the prepandemic period. Next, we estimated the association between the maintenance of (or achieving) hypertension control and the period using generalized estimating equations. We assessed associations between follow-up interval and control separately for periods. Finally, we evaluated the interaction between period and follow-up length. RESULTS: A total of 1,648,424 individuals met the study inclusion criteria. Among individuals with controlled hypertension, the likelihood of maintaining control was lower during the pandemic versus the prepandemic (relative risk: 0.93; 95% CI: 0.93, 0.93). Longer follow-up intervals were associated with a decreasing likelihood of maintaining controlled hypertension in both periods. Accounting for follow-up intervals, the likelihood of maintaining control was 2% lower during the pandemic versus the prepandemic. For uncontrolled hypertension, the likelihood of gaining control was modestly higher during the pandemic versus the prepandemic (relative risk: 1.01; 95% CI: 1.01, 1.01). The likelihood of gaining control decreased with follow-up length during the prepandemic but not pandemic. CONCLUSIONS: During the pandemic, longer follow-up between measurements contributed to the lower likelihood of maintaining control. Those with uncontrolled hypertension were modestly more likely to gain control in the pandemic.

How much magnesium sulfate is needed to "keep total serum magnesium above 2.0 mg/dL"?

For patients at increased risk of life-threating ventricular arrythmias, hospitalists often administer intravenous magnesium sulfate to maintain total serum magnesium concentration (TsMg) above 2 mg/dL. How long each dose keeps TsMg above this threshold is not well known, however. We collected TsMg values from 12,618 veterans who were given 24,363 doses of intravenous magnesium sulfate during 14,901 hospitalizations for acute heart failure. Across dose amounts, the average TsMg dropped below 2.0 mg/dL within 24 h of administration. When we limited our analysis to 2 g doses (the most common dose) and adjusted for baseline TsMg, estimated glomerular filtration rate, oral magnesium supplementation, and loop diuretic dosing, we found that less than half of the adjusted TsMg values remained above 2.0 mg/dL just 12 h after dose administration. Hospitalists should expect, on average, to administer 2 g intravenous magnesium sulfate at least twice daily to maintain total serum magnesium above 2 mg/dL.

Excess mortality in US Veterans during the COVID-19 pandemic: an individual-level cohort study.

BACKGROUND: Most analyses of excess mortality during the COVID-19 pandemic have employed aggregate data. Individual-level data from the largest integrated healthcare system in the US may enhance understanding of excess mortality. METHODS: We performed an observational cohort study following patients receiving care from the Department of Veterans Affairs (VA) between 1 March 2018 and 28 February 2022. We estimated excess mortality on an absolute scale (i.e. excess mortality rates, number of excess deaths) and a relative scale by measuring the hazard ratio (HR) for mortality comparing pandemic and pre-pandemic periods, overall and within demographic and clinical subgroups. Comorbidity burden and frailty were measured using the Charlson Comorbidity Index and Veterans Aging Cohort Study Index, respectively. RESULTS: Of 5 905 747 patients, the median age was 65.8 years and 91% were men. Overall, the excess mortality rate was 10.0 deaths/1000 person-years (PY), with a total of 103 164 excess deaths and pandemic HR of 1.25 (95% CI 1.25-1.26). Excess mortality rates were highest among the most frail patients (52.0/1000 PY) and those with the highest comorbidity burden (16.3/1000 PY). However, the largest relative mortality increases were observed among the least frail (HR 1.31, 95% CI 1.30-1.32) and those with the lowest comorbidity burden (HR 1.44, 95% CI 1.43-1.46). CONCLUSIONS: Individual-level data offered crucial clinical and operational insights into US excess mortality patterns during the COVID-19 pandemic. Notable differences emerged among clinical risk groups, emphasizing the need for reporting excess mortality in both absolute and relative terms to inform resource allocation in future outbreaks.

Point-of-care ultrasound in geriatrics: a national survey of VA medical centers.

BACKGROUND: Point-of-care ultrasound (POCUS) can aid geriatricians in caring for complex, older patients. Currently, there is limited literature on POCUS use by geriatricians. We conducted a national survey to assess current POCUS use, training desired, and barriers among Geriatrics and Extended Care ("geriatric") clinics at Veterans Affairs Medical Centers (VAMCs). METHODS: We conducted a prospective observational study of all VAMCs between August 2019 and March 2020 using a web-based survey sent to all VAMC Chiefs of Staff and Chiefs of geriatric clinics. RESULTS: All Chiefs of Staff (n=130) completed the survey (100% response rate). Chiefs of geriatric clinics ("chiefs") at 76 VAMCs were surveyed and 52 completed the survey (68% response rate). Geriatric clinics were located throughout the United States, mostly at high-complexity, urban VAMCs. Only 15% of chiefs responded that there was some POCUS usage in their geriatric clinic, but more than 60% of chiefs would support the implementation of POCUS use. The most common POCUS applications used in geriatric clinics were the evaluation of the bladder and urinary obstruction. Barriers to POCUS use included a lack of trained providers (56%), ultrasound equipment (50%), and funding for training (35%). Additionally, chiefs reported time utilization, clinical indications, and low patient census as barriers. CONCLUSIONS: POCUS has several potential applications for clinicians caring for geriatric patients. Though only 15% of geriatric clinics at VAMCs currently use POCUS, most geriatric chiefs would support implementing POCUS use as a diagnostic tool. The greatest barriers to POCUS implementation in geriatric clinics were a lack of training and ultrasound equipment. Addressing these barriers systematically can facilitate implementation of POCUS use into practice and permit assessment of the impact of POCUS on geriatric care in the future.

Relative Blood Volume Profiles Hours After Loop Diuretic Administration: A Systematic Review and Meta-analysis.

Background: Plasma refill rates can be estimated by combining measurements of urine output with relative blood volume profiles. Change in plasma refill rates could guide decongestive loop diuretic therapy in acute heart failure. The objective of the study was to assess average relative blood volume profiles generated from 2 or 3 follow-up measurements obtained hours after loop diuretic administration in subjects with vs without baseline congestion. Methods: A systematic review was conducted of articles written in English, French, Spanish, and German, using MEDLINE (1964 to 2019), Cochrane Reviews (1996 to 2019), and Embase (1974 to 2019). Search terms included the following: diuretics, hemoconcentration, plasma volume, and blood volume. We included studies of adults given a loop diuretic with at least one baseline and one follow-up measurement. A single author extracted subject- or group-level blood volume measurements, aggregated them when needed, and converted them to relative changes. Results: Across all 16 studies that met the prespecified inclusion criteria, relative blood volume maximally decreased 9.2% (6.6% to 12.0%) and returned to baseline after 3 or more hours. Compared to subjects without congestion, those with congestion experienced smaller decreases in relative blood volume across all follow-up periods (P = 0.001) and returned to baseline within the final follow-up period. Conclusions: Single doses of loop diuretics produce measurable changes in relative blood volume that follow distinct profiles for subjects with vs without congestion. Measured alongside urine output, these profiles may be used to estimate plasma refill rates-potential patient-specific targets for decongestive therapy across serial diuretic doses.

Contexte: Le taux de remplissage plasmatique peut être estimé en combinant les mesures de la diurèse et les profils volémiques relatifs. Chez les personnes atteintes d'insuffisance cardiaque aiguë, une variation du taux de remplissage plasmatique pourrait guider un traitement décongestif par un diurétique de l'anse. L'étude avait pour objectif d'évaluer les profils volémiques relatifs moyens obtenus dans le cadre de deux ou trois mesures de suivi réalisées quelques heures après l'administration d'un diurétique de l'anse à des sujets présentant ou non une congestion initiale. Méthodologie: Une revue systématique d'articles rédigés en anglais, en français, en espagnol et en allemand a été effectuée au moyen des bases de données MEDLINE (1964 à 2019), Cochrane Reviews (1996 à 2019) et Embase (1974 à 2019). Les termes de recherche comprenaient : diurétiques, hémoconcentration, volume plasmatique et volume sanguin. Nous avons inclus des études portant sur des adultes ayant reçu un diurétique de l'anse chez qui au moins une mesure initiale et une mesure de suivi avaient été effectuées. Un seul auteur a recueilli des mesures du volume sanguin individuelles ou de groupe, les a regroupées, au besoin, et converties en variations relatives. Résultats: Parmi les 16 études qui répondaient aux critères d'inclusion prédéfinis, le volume sanguin relatif a diminué de 9,2 % (de 6,6 % à 12,0 %) et est revenu aux valeurs initiales après trois heures ou plus. Les sujets qui présentaient une congestion ont connu des diminutions du volume sanguin relatif inférieures à celles de ceux n'en présentant pas lors de toutes les périodes de suivi (p = 0,001); le volume sanguin relatif est revenu aux valeurs initiales durant la période finale de suivi. Conclusions: Des doses uniques de diurétique de l'anse produisent des changements mesurables du volume sanguin relatif selon des profils distincts chez les sujets présentant une congestion, comparativement à ceux n'en présentant pas. Utilisés en association avec les mesures de la diurèse, ces profils peuvent servir à estimer le taux de remplissage plasmatique, qui constitue potentiellement une cible particulière au patient qui reçoit une série de doses d'un diurétique comme traitement décongestif.

Absolute and relative excess mortality across demographic and clinical subgroups during the COVID-19 pandemic: an individual-level cohort study from a nationwide healthcare system of US Veterans.

Background: Most analyses of excess mortality during the COVID-19 pandemic have employed aggregate data. Individual-level data from the largest integrated healthcare system in the US may enhance understanding of excess mortality. Methods: We performed an observational cohort study following patients receiving care from the Department of Veterans Affairs (VA) between 1 March 2018 and 28 February 2022. We estimated excess mortality on an absolute scale (i.e., excess mortality rates, number of excess deaths), and a relative scale by measuring the hazard ratio (HR) for mortality comparing pandemic and pre-pandemic periods, overall, and within demographic and clinical subgroups. Comorbidity burden and frailty were measured using the Charlson Comorbidity Index and Veterans Aging Cohort Study Index, respectively. Results: Of 5,905,747 patients, median age was 65.8 years and 91% were men. Overall, the excess mortality rate was 10.0 deaths/1000 person-years (PY), with a total of 103,164 excess deaths and pandemic HR of 1.25 (95% CI 1.25-1.26). Excess mortality rates were highest among the most frail patients (52.0/1000 PY) and those with the highest comorbidity burden (16.3/1000 PY). However, the largest relative mortality increases were observed among the least frail (HR 1.31, 95% CI 1.30-1.32) and those with the lowest comorbidity burden (HR 1.44, 95% CI 1.43-1.46). Conclusions: Individual-level data offered crucial clinical and operational insights into US excess mortality patterns during the COVID-19 pandemic. Notable differences emerged among clinical risk groups, emphasising the need for reporting excess mortality in both absolute and relative terms to inform resource allocation in future outbreaks.

Excess Mortality Among Patients in the Veterans Affairs Health System Compared With the Overall US Population During the First Year of the COVID-19 Pandemic.

Importance: During the first year of the COVID-19 pandemic, there was a substantial increase in the rate of death in the United States. It is unclear whether those who had access to comprehensive medical care through the Department of Veterans Affairs (VA) health care system had different death rates compared with the overall US population. Objective: To quantify and compare the increase in death rates during the first year of the COVID-19 pandemic between individuals who received comprehensive medical care through the VA health care system and those in the general US population. Design, Setting, and Participants: This cohort study compared 10.9 million enrollees in the VA, including 6.8 million active users of VA health care (those with a visit in the last 2 years), with the general population of the US, with deaths occurring from January 1, 2014, to December 31, 2020. Statistical analysis was conducted from May 17, 2021, to March 15, 2023. Main Outcomes and Measures: Changes in rates of death from any cause during the COVID-19 pandemic in 2020 compared with previous years. Changes in all-cause death rates by quarter were stratified by age, sex, race and ethnicity, and region, based on individual-level data. Multilevel regression models were fit in a bayesian setting. Standardized rates were used for comparison between populations. Results: There were 10.9 million enrollees in the VA health care system and 6.8 million active users. The demographic characteristics of the VA populations were predominantly male (>85% in the VA health care system vs 49% in the general US population), older (mean [SD], 61.0 [18.2] years in the VA health care system vs 39.0 [23.1] years in the US population), and had a larger proportion of patients who were White (73% in the VA health care system vs 61% in the US population) or Black (17% in the VA health care system vs 13% in the US population). Increases in death rates were apparent across all of the adult age groups (≥25 years) in both the VA populations and the general US population. Across all of 2020, the relative increase in death rates compared with expected values was similar for VA enrollees (risk ratio [RR], 1.20 [95% CI, 1.14-1.29]), VA active users (RR, 1.19 [95% CI, 1.14-1.26]), and the general US population (RR, 1.20 [95% CI, 1.17-1.22]). Because the prepandemic standardized mortality rates were higher in the VA populations prior to the pandemic, the absolute rates of excess mortality were higher in the VA populations. Conclusions and Relevance: In this cohort study, a comparison of excess deaths between populations suggests that active users of the VA health system had similar relative increases in mortality compared with the general US population during the first 10 months of the COVID-19 pandemic.

Using reflection in nursing practice to enhance patient care.

The ability to reflect on, and learn from, practice experiences is essential for nurses when seeking to provide effective person-centred care. This article outlines the various types of reflection that nurses can use, such as reflection-in-action and reflection-on-action. It also details some of the main models of reflection and explains how nurses might develop their skills in reflection to enhance the quality of patient care. The article provides examples of cases and reflective activities to demonstrate how nurses can use reflection in their practice.

Elucidation of the GSK3α Structure Informs the Design of Novel, Paralog-Selective Inhibitors.

Glycogen synthase kinase 3 (GSK3) remains a therapeutic target of interest for diverse clinical indications. However, one hurdle in the development of small molecule GSK3 inhibitors has been safety concerns related to pan-inhibition of both GSK3 paralogs, leading to activation of the Wnt/ß-catenin pathway and potential for aberrant cell proliferation. Development of GSK3α or GSK3ß paralog-selective inhibitors that could offer an improved safety profile has been reported but further advancement has been hampered by the lack of structural information for GSK3α. Here we report for the first time the crystal structure for GSK3α, both in apo form and bound to a paralog-selective inhibitor. Taking advantage of this new structural information, we describe the design and in vitro testing of novel compounds with up to ∼37-fold selectivity for GSK3α over GSK3ß with favorable drug-like properties. Furthermore, using chemoproteomics, we confirm that acute inhibition of GSK3α can lower tau phosphorylation at disease-relevant sites in vivo, with a high degree of selectivity over GSK3ß and other kinases. Altogether, our studies advance prior efforts to develop GSK3 inhibitors by describing GSK3α structure and novel GSK3α inhibitors with improved selectivity, potency, and activity in disease-relevant systems.

Current Use and Barriers to Point-of-Care Ultrasound in Primary Care: A National Survey of VA Medical Centers.

BACKGROUND: More primary care providers (PCPs) have begun to embrace the use of point-of-care ultrasound (POCUS), but little is known about how PCPs are currently using POCUS and what barriers exist. In this prospective study, the largest systematic survey of POCUS use among PCPs, we assessed the current use, barriers to use, program management, and training needs for POCUS in primary care. METHODS: We conducted a prospective observational study of all VA Medical Centers (VAMCs) between June 2019 and March 2020 using a web-based survey sent to all VAMC Chiefs of Staff and Chiefs of primary care clinics (PCCs). RESULTS: Chiefs of PCCs at 105 VAMCs completed the survey (82% response rate). Only 13% of PCCs currently use POCUS, and the most common applications used were bladder and musculoskeletal ultrasound. Desire for POCUS training exceeded current use, but lack of trained providers (78%), ultrasound equipment (66%), and funding for training (41%) were common barriers. Program infrastructure to support POCUS use was uncommon, and only 9% of VAMCs had local policies related to POCUS. Most PCC chiefs (64%) would support POCUS training. CONCLUSIONS: Current use of POCUS in primary care is low despite the recent growth of POCUS training in Internal Medicine residency programs. Investment in POCUS training and program infrastructure is needed to expand POCUS use in primary care and ensure adequate supervision of trainees.

How Much Is Enough? The Relationship Between Prosocial Effort and Moral Character Judgments.

The amount of effort required to bring about a prosocial outcome can vary from low-handing a stranger the wallet she just dropped-to high-spending days tracking down the owner of a lost wallet. The goal of the current research is to characterize the relationship between prosocial effort and moral character judgments. Does more prosocial effort always lead to rosier moral character judgments? Across four studies (N = 1,658), we find that moral character judgments increase with prosocial effort to a point and then plateau. We find evidence that this pattern is produced, in part, by descriptive and prescriptive norms: exceeding descriptive norms increases moral character judgments, but exceeding prescriptive norms has the opposite effect, which leads to a tapering off of moral character judgments at higher levels of effort.

Current use, training, and barriers in point-of-care ultrasound in hospital medicine: A national survey of VA hospitals.

BACKGROUND: Point-of-care ultrasound (POCUS) can reduce procedural complications and improve the diagnostic accuracy of hospitalists. Currently, it is unknown how many practicing hospitalists use POCUS, which applications are used most often, and what barriers to POCUS use exist. OBJECTIVE: This study aimed to characterize current POCUS use, training needs, and barriers to use among hospital medicine groups (HMGs). DESIGN, SETTING, AND PARTICIPANTS: A prospective observational study of all Veterans Affairs (VA) medical centers was conducted between August 2019 and March 2020 using a web-based survey sent to all chiefs of HMGs. These data were compared to a similar survey conducted in 2015. RESULT: Chiefs from 117 HMGs were surveyed, with a 90% response rate. There was ongoing POCUS use in 64% of HMGs. From 2015 to 2020, procedural POCUS use decreased by 19%, but diagnostic POCUS use increased for cardiac (8%), pulmonary (7%), and abdominal (8%) applications. The most common barrier to POCUS use was lack of training (89%), and only 34% of HMGs had access to POCUS training. Access to ultrasound equipment was the least common barrier (57%). The proportion of HMGs with ≥1 ultrasound machine increased from 29% to 71% from 2015 to 2020. An average of 3.6 ultrasound devices per HMG was available, and 45% were handheld devices. CONCLUSION: From 2015 to 2020, diagnostic POCUS use increased, while procedural use decreased among hospitalists in the VA system. Lack of POCUS training is currently the most common barrier to POCUS use among hospitalists.

Impact of Diagnostic Criteria on UTI Prevalence in Young Infants With Jaundice: A Meta-analysis.

BACKGROUND AND OBJECTIVE: Previously reported prevalence of urinary tract infections (UTIs) in infants with jaundice range from <1% to 25%. However, UTI criteria are variable and, as demonstrated in a meta-analysis on UTI prevalence in bronchiolitis, disease prevalence is greatly impacted by disease definition. The objective of this study was to conduct a systemic review and meta-analysis examining the impact of including positive urinalysis (UA) results as a diagnostic criterion on the estimated UTI prevalence in young infants with jaundice. METHODS: The data sources used were Medline (1946-2020) and Ovid Embase (1976-2020) through January 2020 and bibliographies of retrieved articles. We selected studies reporting UTI prevalence in young infants with jaundice. Data were extracted in accordance with meta-analysis of observational studies in epidemiology guidelines. Random-effects models produced a weighted pooled event rate with 95% confidence intervals (CI). RESULTS: We screened 526 unique articles by abstract and reviewed 53 full-text articles. We included 32 studies and 16 contained UA data. The overall UTI prevalence in young infants with jaundice from all 32 studies was 6.2% (95% CI, 3.9-8.9). From the 16 studies with UA data, the overall UTI prevalence was 8.7% (95% CI, 5.1-13.2), which decreased to 3.6% (95% CI, 2.0-5.8) with positive UA results included as a diagnostic criterion. CONCLUSIONS: The estimated UTI prevalence in young infants with jaundice decreases substantially when UA results are incorporated into the UTI definition. Due to the heterogeneity of study subjects' ages and definitions of jaundice, positive UA results, and UTI, there is uncertainty about the exact prevalence and about which infants with hyperbilirubinemia warrant urine testing.

Lay people's beliefs about creativity: evidence for an insight bias.

Research finds that creative ideas are generated by two cognitive pathways: insight and persistence. However, emerging research suggests people's lay beliefs may not adequately reflect both routes. We propose that people exhibit an insight bias, such that they undervalue persistence and overvalue insight in the creative process.

Comparison of in-person versus tele-ultrasound point-of-care ultrasound training during the COVID-19 pandemic.

BACKGROUND: Lack of training is currently the most common barrier to implementation of point-of-care ultrasound (POCUS) use in clinical practice, and in-person POCUS continuing medical education (CME) courses have been paramount in improving this training gap. Due to travel restrictions and physical distancing requirements during the COVID-19 pandemic, most in-person POCUS training courses were cancelled. Though tele-ultrasound technology has existed for several years, use of tele-ultrasound technology to deliver hands-on training during a POCUS CME course has not been previously described. METHODS: We conducted a retrospective observational study comparing educational outcomes, course evaluations, and learner and faculty feedback from in-person versus tele-ultrasound POCUS courses. The same POCUS educational curriculum was delivered to learners by the two course formats. Data from the most recent pre-pandemic in-person course were compared to tele-ultrasound courses during the COVID-19 pandemic. RESULTS: Pre- and post-course knowledge test scores of learners from the in-person (n = 88) and tele-ultrasound course (n = 52) were compared. Though mean pre-course knowledge test scores were higher among learners of the tele-ultrasound versus in-person course (78% vs. 71%; p = 0.001), there was no significant difference in the post-course test scores between learners of the two course formats (89% vs. 87%; p = 0.069). Both learners and faculty rated the tele-ultrasound course highly (4.6-5.0 on a 5-point scale) for effectiveness of virtual lectures, tele-ultrasound hands-on scanning sessions, and course administration. Faculty generally expressed less satisfaction with their ability to engage with learners, troubleshoot image acquisition, and provide feedback during the tele-ultrasound course but felt learners completed the tele-ultrasound course with a better basic POCUS skillset. CONCLUSIONS: Compared to a traditional in-person course, tele-ultrasound POCUS CME courses appeared to be as effective for improving POCUS knowledge post-course and fulfilling learning objectives. Our findings can serve as a roadmap for educators seeking guidance on development of a tele-ultrasound POCUS training course whose demand will likely persist beyond the COVID-19 pandemic.

A longer shortlist increases the consideration of female candidates in male-dominant domains.

Making it onto the shortlist is often a crucial early step toward professional advancement. For under-represented candidates, one barrier to making the shortlist is the prevalence of informal recruitment practices (for example, colleague recommendations). The current research investigates informal shortlists generated in male-dominant domains (for example, technology executives) and tests a theory-driven intervention to increase the consideration of female candidates. Across ten studies (N = 5,741) we asked individuals to generate an informal shortlist of candidates for a male-dominant role and then asked them to extend the list. We consistently found more female candidates in the extended (versus initial) list. This longer shortlist effect occurs because continued response generation promotes divergence from the category prototype (for example, male technology executives). Studies 3 and 4 supported this mechanism, and study 5 tested the effect of shortlist length on selection decisions. This longer shortlist intervention is a low-cost and simple way to support gender equity efforts.

Retention of Point-of-Care Ultrasound Skills Among Practicing Physicians: Findings of the VA National POCUS Training Program.

BACKGROUND: Point-of-care ultrasound (POCUS) use continues to increase in many specialties, but lack of POCUS training is a known barrier among practicing physicians. Many physicians are obtaining POCUS training through postgraduate courses, but the impact of these courses on skill retention and frequency of POCUS use post-course is unknown. The purpose of this study was to assess the change in POCUS knowledge, skills, and frequency of use after 6-9 months of participating in a brief training course. METHODS: Course participants' POCUS knowledge and hands-on technical skills were tested pre-course using an online, 30-question knowledge test and a directly observed skills test, respectively. The same knowledge and skills tests were repeated immediately post-course and after 6-9 months using remote tele-ultrasound software. Course participants completed a survey on their POCUS use pre-course and after 6-9 months post-course. RESULTS: There were 127 providers who completed the POCUS training course from October 2016 to November 2017. Knowledge test scores increased from a median of 60% to 90% immediately post-course followed by a slight decrease to 87% after 8 months post-course. Median skills test scores for 4 common POCUS applications (heart, lung, abdomen, vascular access) increased 36-74 points from pre-course to immediately post-course with a 2-7-point decrease after 8 months. Providers reported more frequent POCUS use post-course, which suggests application of their POCUS knowledge and skills in clinical practice. More frequent use of cardiac POCUS applications was associated with significantly greater retention of cardiac skills at 8 months. CONCLUSIONS: Practicing physicians can retain POCUS knowledge and hands-on skills 8 months after participating in a 2.5-day POCUS training course, regardless of frequency of POCUS use post-course.

The creative cliff illusion.

Across eight studies, we tested whether people understand the time course of their own creativity. Prior literature finds that creativity tends to improve across an ideation session. Here we compared people's beliefs against their actual creative performance. Consistent with prior research, we found that people's creativity, on aggregate, remained constant or improved across an ideation session. However, people's beliefs did not match this reality. We consistently found that people expected their creativity to decline over time. We refer to this misprediction as the creative cliff illusion. Study 1 found initial evidence of this effect across an ideation task. We found further evidence in a sample with high domain-relevant knowledge (study 2), when creativity judgments were elicited retrospectively (study 3), and across a multiday study (study 5). We theorized the effect occurs because people mistakenly associate creativity (the novelty and usefulness of an idea) with idea production (the ability to generate an idea). Study 4 found evidence consistent with this mechanism. The creative cliff illusion was attenuated among those with high levels of everyday creative experience (study 6) and after a knowledge intervention that increased awareness of the effect (study 7). Demonstrating the impact of creativity beliefs on downstream performance, study 8 found that declining creativity beliefs negatively influenced task persistence and creative performance, suggesting that people underinvest in ideation. This research contributes to work on prediction in the creative domain and demonstrates the importance of understanding creativity beliefs for predicting creative performance.

Discharge-ready volume status in acute decompensated heart failure: a survey of hospitalists.

Acute decompensated heart failure is the leading cause of hospitalization in older adults. Clinical practice guidelines recommend patients should be euvolemic at hospital discharge - yet accurate assessment of volume status is recognized to be exceptionally challenging. This conundrum led us to investigate how hospitalists are assessing volume status and discharge- readiness of patients hospitalized with heart failure. We collected audience response data during a didactic heart failure presentation at the 2019 Society of Hospital Medicine annual meeting. Respondents (n = 216), 76% of whom were practicing physician hospitalists caring for more than 20 acute heart failure patients per year, were presented six questions. Eighteen percent of respondents reported not being able to determine the completeness of decongestion on discharge and 32% reported that complete decongestion was not a treatment target. These findings suggest important differences between guideline recommendations and how hospitalists treat heart failure in current clinical practice.
