RESUMO
Introduction: Japan has the largest aging population with 33% of the population over the age of 60 years. The number of Japanese adults with dementia is estimated to be approximately 4.6 million, comprising nearly 15% of the older adult population. It is critical to administer cognitive assessments early in the disease state that have high reliability and low user burden to detect negative cognitive changes as early as possible; however, current preclinical AD detection methods are invasive, time-consuming, and expensive. A number of traditional and digital cognitive assessments are also available, but many of these tests are time-consuming, taxing to the user, and not widely scalable. The purpose of this study was to incorporate a digital cognitive assessment battery into a standard clinical assessment performed within a Japanese-based neuropsychology clinic to assess the diagnostic accuracy and the relationship between the digital Neurotrack Cognitive Assessment Battery (N-CAB) to traditional cognitive assessments. Methods: Healthy individuals and probable Alzheimer's patients completed the N-CAB, as well as two traditional cognitive assessments, the Mini Mental Status Exam (MMSE) and the Revised Hasegawa's Dementia Scale (HDS-R). Results: Our results demonstrate the Image Pairs hand-response phase of the N-CAB had the highest diagnostic accuracy with 95% sensitivity and 89% specificity to probable Alzheimer's disease. This was closely followed by the Symbol Match assessment, with a 96% sensitivity and 74% specificity to probable Alzheimer's disease. Additionally, Symbol Match and Path Points used in combination resulted in a sensitivity of 94%, specificity of 90%; a model with all N-CAB assessments resulted in a sensitivity and specificity of 100%. All N-CAB assessments had moderate to strong and significant correlations with the MMSE and HDS-R. Discussion: Together, this suggests that the N-CAB assessment battery may be an appropriate alternative for the clinical screening of cognition for earlier detection of Alzheimer's disease.
RESUMO
BACKGROUND: As evidenced by the further reduction in access to testing during the COVID-19 pandemic, there is an urgent, growing need for remote cognitive assessment for individuals with cognitive impairment. The Neurotrack Cognitive Battery (NCB), our response to this need, was evaluated for its temporal reliability and stability as part of ongoing validation testing. OBJECTIVE: The aim of this study is to assess the temporal reliability of the NCB tests (5 total) across a 1-week period and to determine the temporal stability of these measures across 3 consecutive administrations in a single day. METHODS: For test-retest reliability, a range of 29-66 cognitively healthy participants (ages 18-68 years) completed each cognitive assessment twice, 1 week apart. In a separate study, temporal stability was assessed using data collected from 31 different cognitively healthy participants at 3 consecutive timepoints in a single day. RESULTS: Correlations for the assessments were between 0.72 and 0.83, exceeding the standard acceptable threshold of 0.70 for temporal reliability. Intraclass correlations ranged from 0.60 to 0.84, indicating moderate to good temporal stability. CONCLUSIONS: These results highlight the NCB as a brief, easy-to-administer, and reliable assessment for remote cognitive testing. Additional validation research is underway to determine the full magnitude of the clinical utility of the NCB.
RESUMO
PURPOSE: A3 problem solving is part of the Lean management approach to quality improvement (QI). However, few tools are available to assess A3 problem-solving skills. The authors sought to develop an assessment tool for problem-solving A3s with an accompanying self-instruction package and to test agreement in assessments made by individuals who teach A3 problem solving. METHODS: After reviewing relevant literature, the authors developed an A3 assessment tool and self-instruction package over five improvement cycles. Lean experts and individuals from two institutions with QI proficiency and experience teaching QI provided iterative feedback on the materials. Tests of inter-rater agreement were conducted in cycles 3, 4 and 5. The final assessment tool was tested in a study involving 12 raters assessing 23 items on six A3s that were modified to enable testing a range of scores. RESULTS: The intraclass correlation coefficient (ICC) for overall assessment of an A3 (rater's mean on 23 items per A3 compared across 12 raters and 6 A3s) was 0.89 (95% CI 0.75 to 0.98), indicating excellent reliability. For the 20 items with appreciable variation in scores across A3s, ICCs ranged from 0.41 to 0.97, indicating fair to excellent reliability. Raters from two institutions scored items similarly (mean ratings of 2.10 and 2.13, p=0.57). Physicians provided marginally higher ratings than QI professionals (mean ratings of 2.17 and 2.00, p=0.003). Raters averaged completing the self-instruction package in 1.5 hours, then rated six A3s in 2.0 hours. CONCLUSION: This study provides evidence of the reliability of a tool to assess healthcare QI project proposals that use the A3 problem-solving approach. The tool also demonstrated evidence of measurement, content and construct validity. QI educators and practitioners can use the free online materials to assess learners' A3s, provide formative and summative feedback on QI project proposals and enhance their teaching.

With a population of forty million and substantial geographic variation in sociodemographics and health services, California is an important setting in which to study disparities. Its population (37.5 percent White, 39.1 percent Latino, 5.3 percent Black, and 14.4 percent Asian) experienced 59,258 COVID-19 deaths through April 14, 2021-the most of any state. We analyzed California's racial/ethnic disparities in COVID-19 exposure risks, testing rates, test positivity, and case rates through October 2020, combining data from 15.4 million SARS-CoV-2 tests with subcounty exposure risk estimates from the American Community Survey. We defined "high-exposure-risk" households as those with one or more essential workers and fewer rooms than inhabitants. Latino people in California are 8.1 times more likely to live in high-exposure-risk households than White people (23.6 percent versus 2.9 percent), are overrepresented in cumulative cases (3,784 versus 1,112 per 100,000 people), and are underrepresented in cumulative testing (35,635 versus 48,930 per 100,000 people). These risks and outcomes were worse for Latino people than for members of other racial/ethnic minority groups. Subcounty disparity analyses can inform targeting of interventions and resources, including community-based testing and vaccine access measures. Tracking COVID-19 disparities and developing equity-focused public health programming that mitigates the effects of systemic racism can help improve health outcomes among California's populations of color.

BACKGROUND: Academic fellowships in quality improvement (QI) and patient safety (PS) have emerged as one strategy to fill a need for physicians who possess this expertise. The authors aimed to characterise the impact of two such programmes on the graduates and their value to the institutions in which they are housed. METHODS: In 2018, a qualitative study of two US QIPS postgraduate fellowship programmes was conducted. Graduates' demographics and titles were collected from programme files,while perspectives of the graduates and their institutional mentors were collected through individual interviews and analysed using thematic analysis. RESULTS: Twenty-eight out of 31 graduates (90%) and 16 out of 17 (94%) mentors participated in the study across both institutions. At a median of 3 years (IQR 2-4) postgraduation, QIPS fellowship programme graduates' effort distribution was: 50% clinical care (IQR 30-61.8), 48% QIPS administration (IQR 20-60), 28% QIPS research (IQR 17.5-50) and 15% education (7.1-30.4). 68% of graduates were hired in the health system where they trained. Graduates described learning the requisite hard and soft skills to succeed in QIPS roles. Mentors described the impact of the programme on patient outcomes and increasing the acceptability of the field within academic medicine culture. CONCLUSION: Graduates from two QIPS fellowship programmes and their mentors perceive programmatic benefits related to individual career goal attainment and institutional impact. The results and conceptual framework presented here may be useful to other academic medical centres seeking to develop fellowships for advanced physician training programmes in QIPS.

INTRODUCTION: Obstructive sleep apnea (OSA) is an independent cerebrovascular risk factor and highly prevalent in patients with ischemic stroke and transient ischemic attack (TIA). Timely diagnosis and treatment of OSA is important as clinical data suggest that treatment of OSA in the setting of acute ischemic stroke improves functional outcomes. We aimed to assess polysomnography (PSG) utilization in US. Veterans with acute stroke or TIA over a 2-year period. METHODS: Veterans with acute ischemic stroke or TIA presenting to a Veterans Administration Medical Center (VAMC) between October 1, 2015, and June 30, 2017, were included. Demographic, clinical data, and PSG within 12 months of hospital discharge were obtained from the VA Corporate Data Warehouse to determine the rate of PSG testing among those with acute ischemic stroke or TIA. Fisher's exact test and two-sample t tests were used to compare demographic and clinical characteristics for those receiving and not receiving PSG. Mixed effect logistic regression was used to model the association of clinical and demographic characteristics with PSG receipt. RESULTS: In fiscal years (FYs) 2016 and 2017, 9,200 Veterans were admitted to a VAMC with ischemic stroke (6,011) or TIA (3,089). Veterans were elderly (70.5 ± 11.1 years), predominantly male (95.7%), and largely Caucasian (68.0% Caucasian, 26.3% African-American). Just 6.0% of Veterans underwent PSG within 1 year of acute ischemic stroke or TIA in FY 2016, compared to 6.2% in FY 2017 (p = 0.72). Compared to Veterans ≥80 years, those <60 had adjusted OR of 6.73 (4.10-11.05), those 60-69 had OR 4.29 (2.73-6.74), and those 70-79 had OR 2.63 (1.66-4.18) of having PSG. Veterans with diabetes or heart failure had significantly higher odds, whereas those with dementia had significantly lower odds of receiving PSG. CONCLUSION: PSG utilization among US Veterans is low and stable over time, despite recent guidelines recommending PSG among those having stroke or TIA. Older Veterans and those with dementia were unlikely to get PSG, representing especially vulnerable populations.

BACKGROUND: Implementation of new programs within healthcare systems can be extraordinarily complex. Individuals within the same healthcare organization often have different perspectives on how implementation of a new program unfolds over time, and it is not always clear in the midst of implementation what issues are most important or how to address them. An implementation support team within the Veterans Health Administration (VHA) sought to develop an efficient method for eliciting an ongoing, detailed and nuanced account of implementation progress from multiple viewpoints that could support and inform active implementation of two new VHA programs. METHODS: The new Prospectively-Reported Implementation Update and Score ("PRIUS") provided a quick, structured, prospective and open-ended method for individuals to report on implementation progress. PRIUS updates were submitted approximately twice a month. Responding to the prompt "What are some things that happened over the past two weeks that seem relevant from your perspective to the implementation of this project?", individuals scored each update with a number ranging from + 3 to - 3. RESULTS: In 2016-17, individuals submitted over 600 PRIUS updates across the two QI projects. PRIUS-based findings included that staff from different services reported fundamentally different perspectives on program implementation. Rapid analysis and reporting of the PRIUS data led directly to changes in implementation. CONCLUSIONS: The PRIUS provided an efficient, structured method for developing a granular and context-sensitive account of implementation progress. The approach appears to be highly adaptable to a wide range of settings and interventions.

OBJECTIVE: To examine patient safety event reporting behavior by trainees caring for surgical patients compared to other clinicians. DESIGN: Qualitative analysis of a patient safety event reporting system comparing reports entered by trainees to those entered by attending physicians and nurses. Categorical data associated with reports were compared, and free-text event descriptions underwent content analysis focusing on themes related to report completeness and report focus. SETTING: The Hospital of the University of Pennsylvania, an academic tertiary care hospital in Philadelphia, Pennsylvania. PARTICIPANTS: All patient safety event reports related to surgical patients from a 6-month period (July-December 2016). RESULTS: One thousand four hundred twenty-three reports were entered by trainees (T), attendings (A), and nurses (N). Trainees had a lower number of reports entered per reporter compared to nurses (T median [IQR]: 1 [1-2], N: 2 [1-3]), and the highest percentage of reports entered anonymously for any group (T: 28.7%, N: 9.9%, A: 4.6%). The overall distribution of event location and event type differed significantly between groups (p < 0.001). Trainee reports were found to have a broader range of focus, more elements associated with completeness of reports, and more frequent use of blame language. CONCLUSIONS: Surgical trainees report a wide variety of issues in the perioperative, floor, and ICU settings. Their reports often include more details than those entered by other clinicians, but feature higher rates of anonymous reporting and use of blame language. Analysis of patient safety event reports by trainees compared with other healthcare professionals can reveal important insights into the clinical learning environment and areas for safety improvement.

A recent call to address health care disparities has come from the Accreditation Council for Graduate Medical Education's (ACGME's) Clinical Learning Environment Review (CLER) program. The CLER program aspires that faculty and residents will identify the disparities among the patient populations they serve and engage in quality improvement (QI) activities designed to address them. In this Perspective, the authors provide a framework for integrating QI and health equity principles in graduate medical education to meet these ACGME expectations. The authors illustrate their four-step framework by describing a faculty development workshop that provides strategies and tools for embedding equity into existing QI educational efforts and using QI methods to address equity challenges. Using examples, the authors outline how medical educators can begin to integrate QI and equity initiatives to address health care disparities and involve their residents/fellows in the process. In addition, the authors emphasize the importance of applying an equity lens to QI interventions and of recognizing that QI initiatives will have different impacts on outcomes depending on the patient population. The authors conclude by discussing the need for institutional leadership to build capacity and training to improve data collection and reporting of quality metrics by demographic variables; provide resources to disseminate lessons learned; support faculty development to teach and mentor trainees through equity-related QI work; and prioritize time in the curriculum for learners to participate in equity improvement activities.

Alignment between institutions and graduate medical education (GME) regarding quality and safety initiatives (QI) has not been measured. The objective was to determine US internal medicine residency program directors' (IM PDs) perceived resourcing for QI and alignment between GME and their institutions. A national survey of IM PDs was conducted in the Fall of 2013. Multivariable linear regression was used to test association between a novel Integration Score (IS) measuring alignment between GME and the institution via PD perceptions. The response rate was 72.6% (265/365). According to PDs, residents were highly engaged in QI (82%), but adequate funding (14%) and support personnel (37% to 61%) were lower. Higher IS correlated to reports of funding for QI (76.3% vs 54.5%, P = .012), QI personnel (67.3% vs 41.1%, P < .001), research experts (70.5% vs 50.0%, P < .001), and computer experts (69.0% vs 45.8%, P < .001) for QI assistance. Apparent mismatch between GME and institutional resources exists, and the IS may be useful in measuring GME-institutional leadership alignment in QI.

Importance: Many health systems are considering increasing price transparency at the time of order entry. However, evidence of its impact on clinician ordering behavior is inconsistent and limited to single-site evaluations of shorter duration. Objective: To test the effect of displaying Medicare allowable fees for inpatient laboratory tests on clinician ordering behavior over 1 year. Design, Setting, and Participants: The Pragmatic Randomized Introduction of Cost data through the electronic health record (PRICE) trial was a randomized clinical trial comparing a 1-year intervention to a 1-year preintervention period, and adjusting for time trends and patient characteristics. The trial took place at 3 hospitals in Philadelphia between April 2014 and April 2016 and included 98â¯529 patients comprising 142â¯921 hospital admissions. Interventions: Inpatient laboratory test groups were randomly assigned to display Medicare allowable fees (30 in intervention) or not (30 in control) in the electronic health record. Main Outcomes and Measures: Primary outcome was the number of tests ordered per patient-day. Secondary outcomes were tests performed per patient-day and Medicare associated fees. Results: The sample included 142 921 hospital admissions representing patients who were 51.9% white (74 165), 38.9% black (55 526), and 56.9% female (81 291) with a mean (SD) age of 54.7 (19.0) years. Preintervention trends of order rates among the intervention and control groups were similar. In adjusted analyses of the intervention group compared with the control group over time, there were no significant changes in overall test ordering behavior (0.05 tests ordered per patient-day; 95% CI, -0.002 to 0.09; P = .06) or associated fees ($0.24 per patient-day; 95% CI, -$0.42 to $0.91; P = .47). Exploratory subset analyses found small but significant differences in tests ordered per patient-day based on patient intensive care unit (ICU) stay (patients with ICU stay: -0.16; 95% CI, -0.31 to -0.01; P = .04; patients without ICU stay: 0.13; 95% CI, 0.08-0.17; P < .001) and the magnitude of associated fees (top quartile of tests based on fee value: -0.01; 95% CI, -0.02 to -0.01; P = .04; bottom quartile: 0.03; 95% CI, 0.002-0.06; P = .04). Adjusted analyses of tests that were performed found a small but significant overall increase in the intervention group relative to the control group over time (0.08 tests performed per patient day, 95% CI, 0.03-0.12; P < .001). Conclusions and Relevance: Displaying Medicare allowable fees for inpatient laboratory tests did not lead to a significant change in overall clinician ordering behavior or associated fees. Trial Registration: clinicaltrials.gov Identifier: NCT02355496.

Resident physicians routinely order unnecessary inpatient laboratory tests. As hospitalists face growing pressures to reduce low-value services, understanding the factors that drive residents' laboratory ordering can help steer resident training in high-value care. We conducted a qualitative analysis of internal medicine (IM) and general surgery (GS) residents at a large academic medical center to describe the frequency of perceived unnecessary ordering of inpatient laboratory tests, factors contributing to that behavior, and potential interventions to change it. The sample comprised 57.0% of IM and 54.4% of GS residents. Among respondents, perceived unnecessary inpatient laboratory test ordering was self-reported by 88.2% of IM and 67.7% of GS residents, occurring on a daily basis by 43.5% and 32.3% of responding IM and GS residents, respectively. Across both specialties, residents attributed their behaviors to the health system culture, lack of transparency of the costs associated with health care services, and lack of faculty role models that celebrate restraint.

PURPOSE: Over the last decade, the use of oral chemotherapy (OC) for the treatment of cancer has dramatically increased. Despite their route of administration, OCs pose many of the same risks as intravenous agents. In this quality improvement project, we sought to examine our current process for the prescription of OC at the Abramson Cancer Center of the University of Pennsylvania and to improve on its safety. METHODS: A multidisciplinary team that included oncologists, advanced-practice providers, and pharmacists was formed to analyze the current state of our OC practice. Using Lean Six Sigma quality improvement tools, we identified a lack of pharmacist review of the OC prescription as an area for improvement. To address these deficiencies, we used our electronic medical system to route OC orders placed by treating providers to an oncology-specific outpatient pharmacist at the Abramson Cancer Center for review. RESULTS: Over 7 months, 63 orders for OC were placed for 45 individual patients. Of the 63 orders, all were reviewed by pharmacists, and, as a result, 22 interventions were made (35%). Types of interventions included dosage adjustment (one of 22), identification of an interacting drug (nine of 22), and recommendations for additional drug monitoring (12 of 22). CONCLUSION: OC poses many of the same risks as intravenous chemotherapy and should be prescribed and reviewed with the same oversight. At our institution, involvement of an oncology-trained pharmacist in the review of OC led to meaningful interventions in one third of the orders.

BACKGROUND: Although health care organizations (HCOs) are intensely focused on improving the safety of health care, efforts to date have almost exclusively targeted treatment-related issues. The literature confirms that the approaches HCOs use to identify adverse medical events are not effective in finding diagnostic errors, so the initial challenge is to identify cases of diagnostic error. WHY HEALTH CARE ORGANIZATIONS NEED TO GET INVOLVED: HCOs are preoccupied with many quality- and safety-related operational and clinical issues, including performance measures. The case for paying attention to diagnostic errors, however, is based on the following four points: (1) diagnostic errors are common and harmful, (2) high-quality health care requires high-quality diagnosis, (3) diagnostic errors are costly, and (4) HCOs are well positioned to lead the way in reducing diagnostic error. FINDING DIAGNOSTIC ERRORS: Current approaches to identifying diagnostic errors, such as occurrence screens, incident reports, autopsy, and peer review, were not designed to detect diagnostic issues (or problems of omission in general) and/or rely on voluntary reporting. The realization that the existing tools are inadequate has spurred efforts to identify novel tools that could be used to discover diagnostic errors or breakdowns in the diagnostic process that are associated with errors. New approaches--Maine Medical Center's case-finding of diagnostic errors by facilitating direct reports from physicians and Kaiser Permanente's electronic health record--based reports that detect process breakdowns in the followup of abnormal findings--are described in case studies. CONCLUSION: By raising awareness and implementing targeted programs that address diagnostic error, HCOs may begin to play an important role in addressing the problem of diagnostic error.

BACKGROUND: The "Diagnosis and Treatment of Sleep Apnea in Cerebrovascular Disease" (GoToSleep) study is evaluating a strategy to improve the diagnosis and treatment of sleep apnea among veterans with stroke or transient ischemic attack (TIA) who also have hypertension. Specifically, the GoToSleep study was designed to overcome some of the barriers that exist within the Veterans Health Administration (VHA) to the timely diagnosis and treatment of sleep apnea by using ambulatory home-based polysomnography and auto-titrating continuous positive airway pressure (CPAP) to reduce the reliance on laboratory-based sleep studies. METHODS: The GoToSleep study is a prospective, multi-site, randomized, controlled strategy trial among an expected 318 veterans with cerebrovascular disease and hypertension who are assigned to an intervention group or a control group. Patients in the intervention group receive unattended polysomnography at baseline, and those with sleep apnea receive auto-titrating CPAP therapy for up to one year. Patients in the control group receive usual care and unattended polysomnography at the end of the study to identify the rate of undiagnosed sleep apnea. The primary objectives of the GoToSleep study are to determine whether a diagnostic and therapeutic intervention strategy among veterans with cerebrovascular disease and hypertension improves: (1) detection of sleep apnea; (2) appropriate treatment for sleep apnea; and (3) control of hypertension. Twenty-four-hour blood pressure assessments are made at baseline and at the end of the one-year study period for both groups. Antihypertensive medications and their doses are recorded at the time of the 24-hour blood pressure measurements. DISCUSSION: This manuscript provides the rationale for 4 key components of the design of the GoToSleep trial: the inclusion of patients with cerebrovascular disease and hypertension without the use of a measure of daytime sleepiness as an eligibility criterion; the use of portable polysomnography and auto-titrating CPAP in patients' homes rather than using sleep laboratory polysomnography with fixed pressure CPAP; the analytic approach to evaluating change in blood pressure in the context of change in antihypertensive medications; and the use of a usual care control group.

BACKGROUND: Within the Veterans Health Administration (VHA), approximately 6000 veterans are hospitalized with acute ischemic stroke annually. We examined the use and misuse of thrombolytic therapy with tissue plasminogen activator (tPA) in a national sample of veterans who were admitted to a VHA Medical Center (VAMC) with acute ischemic stroke. METHODS: Medical record reviews were conducted on 5000 acute stroke patients who were admitted to a VAMC in 2007. Patients were defined as eligible to receive tPA if they arrived at the hospital within 3 hours of stroke symptom onset and had no contraindications to tPA. We compared eligible patients who received tPA to those who did not and examined the distribution of eligible patients across the 129 VAMCs included in this study. RESULTS: Among the 3931 ischemic stroke patients, 174 (4.4%) were eligible for tPA. Among the 135 patients who arrived within 2 hours of symptom onset which allowed adequate time for testing and evaluation, 19 (14.1%) received tPA. An additional 11 patients received tPA but did not meet eligibility criteria. Eligible patients receiving tPA were similar to eligible patients not receiving tPA in terms of clinical conditions and time to brain imaging. Among the 30 patients that received tPA, 5 (16.6%) received the wrong dose. Among the 85 VAMCs that received ≥1 eligible patient, on average 2.3 patients were eligible for tPA annually. CONCLUSIONS: Relatively few eligible veterans receive thrombolysis across the VHA system. Strategies to improve thrombolysis delivery will have to account for the low annual volume of eligible stroke patients cared for at individual VAMCs.

Second-hand exposure to aerosols containing fentanyl and other opiates during surgical procedures has been implicated as possibly contributing to maintenance of addiction among medical professionals, specifically anesthesiologists. This article outlines a pilot study that was conducted to verify a reported finding fentanyl in the air of operating suites. Environmental fentanyl air sampling and analysis methods were developed and evaluated for this study. Multiple sampling media and extraction solvents were evaluated for trace fentanyl air sampling. Non-specific binding losses were reduced by using silanized binder-free glass fiber sampling media with subsequent methanol extraction. Filtration air samples were then collected in surgical suites during the entire operation time from two cardiovascular surgical procedures. Both surgical procedures were conducted at the same hospital but on different days. Samples were extracted and analyzed by high-performance liquid chromatography/tandem mass spectrometry using a capillary high-performance liquid chromatography coupled to a quadrupole time-of-flight mass spectrometer. The total air volume collected per surgery was 290 to 300 L at a rate of 1 LPM giving an limit of quantification for fentanyl of 57 pg/m(3) air (17 pg/filter). No fentanyl was detected in the air during cardiovascular surgical operations from either surgical suite.
