Investigating the Neural Basis of the Loud-first Principle of the Iambic-Trochaic Law.

The perception of rhythmic patterns is crucial for the recognition of words in spoken languages, yet it remains unclear how these patterns are represented in the brain. Here, we tested the hypothesis that rhythmic patterns are encoded by neural activity phase-locked to the temporal modulation of these patterns in the speech signal. To test this hypothesis, we analyzed EEGs evoked with long sequences of alternating syllables acoustically manipulated to be perceived as a series of different rhythmic groupings in English. We found that the magnitude of the EEG at the syllable and grouping rates of each sequence was significantly higher than the noise baseline, indicating that the neural parsing of syllables and rhythmic groupings operates at different timescales. Distributional differences between the scalp topographies associated with each timescale suggests a further mechanistic dissociation between the neural segmentation of syllables and groupings. In addition, we observed that the neural tracking of louder syllables, which in trochaic languages like English are associated with the beginning of rhythmic groupings, was more robust than the neural tracking of softer syllables. The results of further bootstrapping and brain-behavior analyses indicate that the perception of rhythmic patterns is modulated by the magnitude of grouping alternations in the neural signal. These findings suggest that the temporal coding of rhythmic patterns in stress-based languages like English is supported by temporal regularities that are linguistically relevant in the speech signal.

An Electronic Medical Record Intervention to Increase Pharmacologic Prophylaxis for Venous Thromboembolism in Emergency Department Observation Patients.

STUDY OBJECTIVE: The role of venous thromboembolism (VTE) prophylaxis among patients receiving emergency department (ED) observation unit care is unclear. We investigated an electronic health record-based clinical decision support tool aimed at increasing pharmacologic VTE prophylaxis use among at-risk patients placed in ED observation units. METHODS: We conducted an interrupted time-series study of an Epic-based best practice advisory implemented in May 2019 at a health care system comprising 2 academic medical centers and 4 community hospitals with dedicated ED observation units. The best practice advisory alerted staff at 24 hours to conduct a risk assessment and linked to a VTE prophylaxis order set. We used an interrupted time series, Bayesian structured time series, and a multivariable mixed-effect regression model to estimate the intervention effect. RESULTS: Prior to the best practice advisory implementation, there were 8,895 ED observation unit patients with a length of stay more than or equal to 24 hours, and 0.9% received pharmacologic VTE prophylaxis. Afterward, there were 12,664 ED observation unit patients with a length of stay more than or equal to 24 hours, and 4.8% received pharmacologic VTE prophylaxis. The interrupted time series and causal impact analysis showed a statistically significant increase in VTE prophylaxis (eg, absolute percent difference 3.8%, 95% confidence interval 3.5 to 4.1). In a multivariable model, only the intervention was significantly associated with receiving VTE prophylaxis (odds ratio 4.56, 95% confidence interval 2.22 to 9.37). CONCLUSION: An electronic health record-based alert helped to prompt staff caring for ED observation unit patients at risk for VTE with prolonged visits to order recommended pharmacologic prophylaxis. The best risk assessment model to use and the true incidence of VTE events in this population are unclear.

Measuring Medication Use, Obstacles, and Knowledge in Individuals With Cirrhosis.

BACKGROUND & AIMS: Although patient knowledge is modifiable, there are no widely accepted tools to measure patient understanding during cirrhosis care. We aimed to develop and validate "My Cirrhosis Coach" (MCC), a personalized, self-administered questionnaire to evaluate cirrhosis-related medication use, obstacles, and understanding. METHODS: Adults with cirrhosis were prospectively enrolled at 3 tertiary centers from July 2016 through July 2020. Psychometrics including confirmatory factor analysis was used to develop and validate a final questionnaire. Content validity was measured via the content validity index and expert performance. Discriminant validity was assessed by comparing scores between groups hypothesized to have varying performance. RESULTS: The MCC was tested in a diverse cohort (n = 713) with cirrhosis and its complications including ascites (45%) and hepatic encephalopathy (33%) with median Model for End-Stage Liver Disease-Sodium 10 (interquartile range, 9-15). A 6-factor model of the MCC fit the data well (root mean square error of approximation, 0.22; comparative fit index, 0.96; standardized root mean squared residual, 0.104; final domains: Medication Use & Accessibility, Medication Obstacles, Lactulose Use, Diuretic Use, Beta Blocker Use, and Dietary Sodium Use). The MCC had excellent content validity (content validity index, 81%-94%) and accuracy (91%-100%) ratings by experts. Mean domain scores ranged from 1.1 to 2.6 (range, 0-3; 3 indicating better performance). Those with a cirrhosis complication scored higher in the relevant medication domain (ie, diuretic use score in ascites). Compared with outpatients, inpatients scored higher in all knowledge domains except salt use and reported more medication obstacles. Scores differed by income, education level, and having an adult at home. CONCLUSIONS: In a large, diverse cohort, we validated the MCC, which can serve to standardize medication use and knowledge measurement in clinical practice and education-based studies in cirrhosis.

Implementation of an Electronic Alert to Improve Timeliness of Second Dose Antibiotics for Patients With Suspected Serious Infections in the Emergency Department: A Quasi-Randomized Controlled Trial.

STUDY OBJECTIVE: Delays in the second dose of antibiotics in the emergency department (ED) are associated with increased morbidity and mortality in patients with serious infections. We analyzed the influence of clinical decision support to prevent delays in second doses of broad-spectrum antibiotics in the ED. METHODS: We allocated adult patients who received cefepime or piperacillin/tazobactam in 9 EDs within an integrated health care system to an electronic alert that reminded ED clinicians to reorder antibiotics at the appropriate interval vs usual care. The primary outcome was a median delay in antibiotic administration. Secondary outcomes were rates of intensive care unit (ICU) admission, hospital mortality, and hospital length of stay. We included a post hoc secondary outcome of frequency of major delay (>25% of expected interval for second antibiotic dose). RESULTS: A total of 1,113 ED patients treated with cefepime or piperacillin/tazobactam were enrolled in the study, of whom 420 remained under ED care when their second dose was due and were included in the final analysis. The clinical decision support tool was associated with reduced antibiotic delays (median difference 35 minutes, 95% confidence interval [CI], 5 to 65). There were no differences in ICU transfers, inpatient mortality, or hospital length of stay. The clinical decision support tool was associated with decreased probability of major delay (absolute risk reduction 13%, 95% CI, 6 to 20). CONCLUSIONS: The implementation of a clinical decision support alert reminding clinicians to reorder second doses of antibiotics was associated with a reduction in the length and frequency of antibiotic delays in the ED. There was no effect on the rates of ICU transfers, inpatient mortality, or hospital length of stay.

Tailoring Surveillance Colonoscopy in Patients With Advanced Adenomas.

BACKGROUND & AIMS: Patients with advanced colorectal adenomas (AAs) are directed to undergo intensive surveillance. However, the benefit derived from surveillance may be outweighed by the risk of death from non-colorectal cancer (CRC) causes, leading to uncertainty on how best to individualize follow-up. The aim of this study was to derive a risk prediction model and risk index that estimate and stratify the risk for non-CRC cancer mortality (NCM) subsequent to diagnosis and removal of AA. METHODS: We conducted a retrospective cohort study of veterans ≥40 years old who had colonoscopy for diagnostic or screening indications at 13 Veterans Affairs Medical Centers between 2002 and 2009 and had 1 or more AAs. The primary outcome was NCM using a fixed follow-up time period of 5 years. Logistic regression using the lasso technique was used to identify factors independently associated with NCM, and an index based on points from regression coefficients was constructed to estimate risk of 5-year NCM. RESULTS: We identified 2943 veterans with AA (mean age [standard deviation] 63 [8.6] years, 98% male, 74% white), with an overall 5-year mortality of 16.7%, which was nearly all due to NCM (16.6%). Age, comorbidity burden, specific comorbid conditions, and hospitalization within the preceding year were independently associated with NCM. The risk prediction model had a goodness of fit (calibration) P value of .41 and c-statistic (discrimination) of 0.74 (95% confidence interval, 0.71-0.76). On the basis of comparable 5-year risks of NCM, the scores comprised 3 risk categories: low (score of 0-1), intermediate (score of 2-4), and high (score of ≥5), in which NCM occurred in 6.5%, 14.1%, and 33.2%, respectively. CONCLUSIONS: We derived a risk prediction model that identifies veterans with advanced adenomas who are at high risk of NCM within 5 years, and who are thus unlikely to benefit from further surveillance.

Age-specific rates of hospital transfers in long-stay nursing home residents.

INTRODUCTION: hospital transfers and admissions are critical events in the care of nursing home residents. We sought to determine hospital transfer rates at different ages. METHODS: a cohort of 1,187 long-stay nursing home residents who had participated in a Centers for Medicare and Medicaid demonstration project. We analysed the number of hospital transfers of the study participants recorded by the Minimum Data Set. Using a modern regression technique, we depicted the annual rate of hospital transfers as a smooth function of age. RESULTS: transfer rates declined with age in a nonlinear fashion. Rates were the highest among residents younger than 60 years of age (1.30-2.15 transfers per year), relatively stable between 60 and 80 (1.17-1.30 transfers per year) and lower in those older than 80 (0.77-1.17 transfers per year). Factors associated with increased risk of transfers included prior diagnoses of hip fracture (annual incidence rate ratio or IRR: 2.057, 95% confidence interval (CI): [1.240, 3.412]), dialysis (IRR: 1.717, 95% CI: [1.313, 2.246]), urinary tract infection (IRR: 1.755, 95% CI: [1.361, 2.264]), pneumonia (IRR: 1.501, 95% CI: [1.072, 2.104]), daily pain (IRR: 1.297, 95% CI: [1.055,1.594]), anaemia (IRR: 1.229, 95% CI [1.068, 1.414]) and chronic obstructive pulmonary disease (IRR: 1.168, 95% CI: [1.010,1.352]). Transfer rates were lower in residents who had orders reflecting preferences for comfort care (IRR: 0.79, 95% CI: [0.665, 0.936]). DISCUSSION: younger nursing home residents may require specialised interventions to reduce hospital transfers; declining transfer rates with the oldest age groups may reflect preferences for comfort-focused care.

The design and conduct of a pragmatic cluster randomized trial of an advance care planning program for nursing home residents with dementia.

BACKGROUND/AIMS: A significant number of people with Alzheimer's disease or related dementia diagnoses will be cared for in nursing homes near the end of life. Advance care planning (ACP), the process of eliciting and documenting patient-centered preferences for care, is considered essential to providing high quality care for this population. Nursing homes are currently required by regulations to offer ACP to residents and families, but no training requirements exist for nursing home staff, and approaches to fulfilling this regulatory and ethical responsibility vary. As a result, residents may receive care inconsistent with their goals, such as unwanted hospitalizations. Pragmatic trials offer a way to develop and test ACP in real-world settings to increase the likelihood of adoption of sustainable best practices. METHODS: The "Aligning Patient Preferences-a Role Offering Alzheimer's patients, Caregivers, and Healthcare Providers Education and Support (APPROACHES)" project is designed to pragmatically test and evaluate a staff-led program in 137 nursing homes (68 = intervention, 69 = control) owned by two nursing home corporations. Existing nursing home staff receive standardized training and implement the ACP Specialist program under the supervision of a corporate lead. The primary trial outcome is the annual rate of hospital transfers (admissions and emergency department visits). Consistent with the spirit of a pragmatic trial, study outcomes rely on data already collected for quality improvement, clinical, or billing purposes. Configurational analysis will also be performed to identify conditions associated with implementation. RESULTS: Partnerships with large corporate companies enable the APPROACHES trial to rely on corporate infrastructure to roll out the intervention, with support for a corporate implementation lead who is charged with the initial introduction and ongoing support for nursing home-based ACP Specialists. These internal champions connect the project with other company priorities and use strategies familiar to nursing home leaders for the initiation of other programs. Standardized data collection across nursing homes also supports the conduct of pragmatic trials in this setting. DISCUSSION: Many interventions to improve care in nursing homes have failed to demonstrate an impact or, if successful, maintain an impact over time. Pragmatic trials, designed to test interventions in real-world contexts that are evaluated through existing data sources collected routinely as part of clinical care, are well suited for the nursing home environment. A robust program that increases access to ACP for nursing home residents has the potential to increase goal-concordant care and is expected to reduce hospital transfers. If successful, the ACP Specialist Program will be primed for rapid translation into nursing home practice to reduce unwanted, burdensome hospitalizations and improve the quality of care for residents with dementia.

Derivation and validation of a predictive model for advanced colorectal neoplasia in asymptomatic adults.

OBJECTIVE: Knowing risk for advanced colorectal neoplasia (AN) could help patients and providers choose among screening tests, improving screening efficiency and uptake. We created a risk prediction model for AN to help decide which test might be preferred, a use not considered for existing models. DESIGN: Average-risk 50-to-80-year olds undergoing first-time screening colonoscopy were recruited from endoscopy units in Indiana. We measured sociodemographic and physical features, medical and family history and lifestyle factors and linked these to the most advanced finding. We derived a risk equation on two-thirds of the sample and assigned points to each variable to create a risk score. Scores with comparable risks were collapsed into risk categories. The model and score were tested on the remaining sample. RESULTS: Among 3025 subjects in the derivation set (mean age 57.3 (6.5) years; 52% women), AN prevalence was 9.4%. The 13-variable model (c-statistic=0.77) produced three risk groups with AN risks of 1.5% (95% CI 0.72% to 2.74%), 7.06% (CI 5.89% to 8.38%) and 27.26% (CI 23.47% to 31.30%) in low-risk, intermediate-risk and high-risk groups (p value <0.001), containing 23%, 59% and 18% of subjects, respectively. In the validation set of 1475 subjects (AN prevalence of 8.4%), model performance was comparable (c-statistic=0.78), with AN risks of 2.73% (CI 1.25% to 5.11%), 5.57% (CI 4.12% to 7.34%) and 25.79% (CI 20.51% to 31.66%) in low-risk, intermediate-risk and high-risk subgroups, respectively (p<0.001), containing proportions of 23%, 59% and 18%. CONCLUSION: Among average-risk persons, this model estimates AN risk with high discrimination, identifying a lower risk subgroup that may be screened non-invasively and a higher risk subgroup for which colonoscopy may be preferred. The model could help guide patient-provider discussions of screening options, may increase screening adherence and conserve colonoscopy resources.

SymTrak-8 as a Brief Measure for Assessing Symptoms in Older Adults.

BACKGROUND: Patient- and caregiver-reported 23-item SymTrak scales were validated for monitoring clinically actionable symptoms and impairments associated with multiple chronic conditions (MCCs) in older adults. Items capture physical and emotional symptoms and impairments in physical and cognitive functioning. An abbreviated SymTrak is desirable when response burden is a concern. OBJECTIVE: Develop and validate the 8-item SymTrak. DESIGN AND PARTICIPANTS: Secondary analysis of SymTrak validation study; 600 participants (200 patient-caregiver dyads; 200 patients without an identified caregiver). MAIN MEASURES: Demographic questions, SymTrak, and Health Utility Index Mark 3 (HUI3). KEY RESULTS: SymTrak-8 demonstrated good fit to a one-factor model using confirmatory factor analysis (CFA). Concurrent criterion validity was supported by high standardized linear regression coefficients (STB) between baseline SymTrak-8 total score (independent variable) and baseline HUI3 preference-based overall HRQOL utility score (dependent variable; 0 = death, 1 = perfect health), after adjusting for demographics, comorbid conditions, and medications, with strength comparable to SymTrak-23 (STB = - 0.81 and - 0.84, respectively, for SymTrak-8 and SymTrak-23, when patient-reported; and - 0.60 and - 0.62, respectively, when caregiver-reported). Coefficient alpha (0.74; 0.76) and 24-h test-retest reliability (0.83; 0.87) were high for SymTrak-8 for patients and caregivers, respectively. The convergent correlation between brief and parent SymTrak scales was high (0.94). SymTrak-8 demonstrated approximate normality and a linear relationship with SymTrak-23 and HUI3. Importantly, a 3-month change in SymTrak-8 was sensitive to detecting the criterion (3-month reliable change categories; improved, stable, declined in HUI3 overall utility), with results comparable to SymTrak-23. CONCLUSIONS: SymTrak-8 total score demonstrates internal reliably, test-retest reliability, criterion validity, and sensitivity to change that are comparable to SymTrak-23. Thus, patient- or caregiver-reported SymTrak-8 is a viable option for identifying and monitoring the aggregate effect of symptoms and functional impairments in patients with multimorbidity when response burden is a concern.

The mediating role of avoidant coping in the relationships between physical, psychological, and social wellbeing and distress in breast cancer survivors.

OBJECTIVE: Many breast cancer survivors (BCSs) recover from the negative sequelae of cancer treatment. However, some report persistent and disruptive distress well into disease-free survivorship. More information is needed on the predictors of distress in this growing population of BCS, including the role of avoidant coping, or attempts to avoid thoughts, feelings, and reminders of cancer, in mediating the relationship between distress and psychological, physical, and social domains of well-being. METHODS: In a large cross-sectional study, BCS (n = 1,127), who were 3 to 8 years post-diagnosis, completed a survey assessing demographic characteristics, medical history, distress (anxiety and depressive symptoms), avoidant coping, and physical (fatigue), psychological (fear of recurrence, attention, body image), and social (social support from a partner, social constraints from a partner) well-being. Multiple mediation analyses were conducted to determine if avoidant coping mediated the relationship between each distress variable (anxiety and depressive symptoms) and each well-being (fear of recurrence, attention, body image, fatigue, social support, and social constraints) variable. RESULTS: In all six mediation models, avoidant coping significantly (p < 0.001) mediated the relationship between each well-being variable (fear of recurrence, attention, body image, fatigue, social support, and social constraints) and each distress indicator (depression and anxiety). Avoidant coping mediated 19%-54% of the effects of the contributing factors on the distress variables. CONCLUSIONS: Avoidant coping may indicate risk for, or presence of, distress among BCS. Interventions to reduce distress may benefit from addressing avoidant coping styles.

Clinical Decision Support Reduces Unnecessary Tetanus Vaccinations in the Emergency Department.

STUDY OBJECTIVE: Tetanus is the most common vaccination given in the emergency department; yet, administrations of tetanus vaccine boosters in the ED may not comply with the US Centers for Disease Control and Prevention's recommended vaccination schedule. We implemented a clinical decision support alert in the electronic health record that warned providers when ordering a tetanus vaccine if a prior one had been given within 10 years and studied its efficacy to reduce potentially unnecessary vaccines in the ED. METHODS: This was a retrospective, quasi-experimental, 1-group, pretest-posttest study in 3 hospital EDs in Boston, MA. We studied adult patients for whom tetanus vaccines were ordered despite a history of vaccination within the prior 10 years. We compared the number of potentially unnecessary tetanus vaccine administrations in a baseline phase (when the clinical decision support alert was not visible) versus an intervention phase. RESULTS: Of eligible patients, 22.1% (95% confidence interval [CI] 21.8% to 22.4%) had prior tetanus vaccines within 5 years, 12.8% (95% CI 12.5% to 13.0%) within 5 to 10 years, 3.8% (95% CI 3.6% to 3.9%) more than 10 years ago, and 61.3% (95% CI 60.9% to 61.7%) had no prior tetanus vaccination documentation. Of 60,983 encounters, 337 met the inclusion criteria. A tetanus vaccination was administered in 91% (95% CI 87% to 96%) of encounters in the baseline phase, compared to 55% (95% CI 47% to 62%) during the intervention. The absolute risk reduction was 36.7% (95% CI 28.0% to 45.4%), and the number of encounters needed to alert to avoid 1 potentially unnecessary tetanus vaccine (number needed to treat) was 2.7 (95% CI 2.2% to 3.6%). For patients with tetanus vaccines within the prior 5 years, the absolute risk reduction was 47.9% (95% CI 35.5 % to 60.3%) and the number needed to treat was 2.1 (95% CI 1.7% to 2.8%). CONCLUSION: A clinical decision support alert that warns ED clinicians that a patient may have an up-to-date tetanus vaccination status reduces potentially unnecessary vaccinations.

Responsiveness of PROMIS and Patient Health Questionnaire (PHQ) Depression Scales in three clinical trials.

BACKGROUND: The PROMIS depression scales are reliable and valid measures that have extensive normative data in general population samples. However, less is known about how responsive they are to detect change in clinical settings and how their responsiveness compares to legacy measures. The purpose of this study was to assess and compare the responsiveness of the PROMIS and Patient Health Questionnaire (PHQ) depression scales in three separate samples. METHODS: We used data from three clinical trials (two in patients with chronic pain and one in stroke survivors) totaling 651 participants. At both baseline and follow-up, participants completed four PROMIS depression fixed-length scales as well as legacy measures: Patient Health Questionnaire 9-item and 2-item scales (PHQ-9 and PHQ-2) and the SF-36 Mental Health scale. We measured global ratings of depression change, both prospectively and retrospectively, as anchors to classify patients as improved, unchanged, or worsened. Responsiveness was assessed with standardized response means, statistical tests comparing change groups, and area-under-curve analysis. RESULTS: The PROMIS depression and legacy scales had generally comparable responsiveness. Moreover, the four PROMIS depression scales of varying lengths were similarly responsive. In general, measures performed better in detecting depression improvement than depression worsening. For all measures, responsiveness varied based on the study sample and on whether depression improved or worsened. CONCLUSIONS: Both PROMIS and PHQ depression scales are brief public domain measures that are responsive (i.e., sensitive to change) and thus appropriate as outcome measures in research as well as for monitoring treatment in clinical practice. Trial registration ClinicalTrials.gov ID: NCT01236521, NCT01583985, NCT01507688.

Performance Characteristics of Fecal Immunochemical Tests for Colorectal Cancer and Advanced Adenomatous Polyps: A Systematic Review and Meta-analysis.

Background: Studies report inconsistent performance of fecal immunochemical tests (FITs) for colorectal cancer (CRC) and advanced adenomas. Purpose: To summarize performance characteristics of FITs for CRC and advanced adenomas in average-risk persons undergoing screening colonoscopy (reference standard) and to identify factors affecting these characteristics. Data Sources: Ovid MEDLINE, PubMed, Embase, and the Cochrane Library from inception through October 2018; reference lists of studies and reviews. Study Selection: Two reviewers independently screened records to identify published English-language prospective or retrospective observational studies that evaluated FIT sensitivity and specificity for colonoscopic findings in asymptomatic, average-risk adults. Data Extraction: Two authors independently extracted data and evaluated study quality. Data Synthesis: Thirty-one studies (120 255 participants; 18 FITs) were included; all were judged to have low to moderate risk of bias. Performance characteristics depended on the threshold for a positive result. A threshold of 10 µg/g resulted in sensitivity of 0.91 (95% CI, 0.84 to 0.95) and a negative likelihood ratio of 0.10 (CI, 0.06 to 0.19) for CRC, whereas a threshold of greater than 20 µg/g resulted in specificity of 0.95 (CI, 0.94 to 0.96) and a positive likelihood ratio of 15.49 (CI, 9.82 to 22.39). For advanced adenomas, sensitivity was 0.40 (CI, 0.33 to 0.47) and the negative likelihood ratio was 0.67 (CI, 0.57 to 0.78) at 10 µg/g, and specificity was 0.95 (CI, 0.94 to 0.96) and the positive likelihood ratio was 5.86 (CI, 3.77 to 8.97) at greater than 20 µg/g. Studies had low to high heterogeneity, depending on the threshold. Although several FITs had adequate performance, sensitivity and specificity for CRC for 1 qualitative FIT were 0.90 and 0.91, respectively, at its single threshold of 10 µg/g; positive and negative likelihood ratios were 10.13 and 0.11, respectively. Comparison of 3 FITs at 3 thresholds was inconclusive: CIs overlapped, and the comparisons were across rather than within studies. Limitations: Only English-language studies were included. Incomplete reporting limited quality assessment of some evidence. Performance characteristics are for 1-time rather than serial testing. Conclusion: Single-application FITs have moderate to high sensitivity and specificity for CRC, depending on the positivity threshold. Sensitivity of 1-time testing for advanced adenomas is low, regardless of the threshold. Primary Funding Source: Department of Medicine, Indiana University School of Medicine.

Psychometric development of a new body image scale for breast cancer survivors.

The purpose of this study was to psychometrically test a body image scale for breast cancer survivors (BCS). Data (n = 1127 BCSs) were obtained via telephone and mailed questionnaires. Psychometric testing was conducted using Cronbach's alpha, item-total correlations, factor analysis, linear regression, and Pearson's correlations. Data demonstrated a unidimensional seven-item scale with Cronbach's alpha = 0.88 and item-total correlations ranging from 0.367 to 0.829. Construct validity was demonstrated with 48% of the variance in well-being explained by constructs in the conceptual model [F(14,784) = 48.35, p < .001]. The body image scale demonstrated high internal consistency reliability, unidimensionality, and construct validity.

Prevalence of Advanced, Precancerous Colorectal Neoplasms in Black and White Populations: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Colorectal cancer incidence and mortality are higher in black vs white populations. The reasons for these disparities are not clear, yet some guidelines recommend screening black persons for colorectal cancer starting at 40-45 years of age. We performed a systematic review and meta-analysis to compare the prevalence of advanced adenomas (AAs) and advanced precancerous colorectal neoplasms (ACNs) between asymptomatic black and white screen-eligible adults. METHODS: We searched Ovid MEDLINE, PubMed, Embase, and the Cochrane Library to identify articles (published from 1946 through June 2017) that reported prevalence values of AA or ACN in average-risk black and white individuals undergoing screening colonoscopy. Two authors independently assessed study quality and risk for bias using a modified validated quality assessment instrument. In accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 2 authors independently abstracted descriptive and quantitative data from each study. We performed a random-effects meta-analysis to determine risk differences and odds ratios (ORs). RESULTS: Of 1653 articles, we identified 9 studies for analysis that included 302,128 individuals. Six of the 9 studies were of high methodologic quality, and had a low risk for bias. In these 9 studies, the overall prevalence values for AA and ACN did not differ significantly between black (6.57%) and white (6.20%) screened individuals (OR 1.03; 95% confidence interval [CI] 0.81-1.30). In a subgroup of 5 studies, the prevalence of proximal AA and ACN was significantly higher in black (3.30%) than in white (2.42%) screened individuals (OR 1.20; 95% CI 1.12-1.30). Excluding the largest study did not affect overall prevalence (OR 0.99; CI 0.73-1.34) but did eliminate the difference in prevalence of proximal AA or ACN (OR 1.48; 95% CI 0.87-2.52). CONCLUSIONS: In this meta-analysis, we found the overall prevalence of AA and ACN did not differ significantly between average-risk black and white persons, indicating that the age at which to begin colorectal cancer screening need not differ based on race alone.

Reliability and Validity of SymTrak, a Multi-Domain Tool for Monitoring Symptoms of Older Adults with Multiple Chronic Conditions.

BACKGROUND: A reliable and valid clinically practical multi-domain self-report and caregiver-report tool is needed for tracking actionable symptoms in primary care for elderly patients with multiple chronic conditions (MCCs). OBJECTIVE: Assess internal consistency reliability, test-retest reliability, construct validity, and sensitivity to change for SymTrak. DESIGN AND PARTICIPANTS: Among 600 (200 patient-caregiver dyads, 200 patients without an identified caregiver) participants, SymTrak was telephone interviewer-administered at baseline and 3-month follow-up, and at 24 h post-baseline for assessing test-retest reliability in a random subsample of 180 (60 dyads, 60 individual patients) participants. MAIN MEASURES: Demographic questions, SymTrak, Health Utility Index Mark 3 (HUI3). KEY RESULTS: Exploratory factor analysis indicated a single dominant dimension for SymTrak items for both patients and caregivers. Coefficient alpha and 24-h test-retest reliability, respectively, were high for the 23-item SymTrak total score for both patient-reported (0.85; 0.87) and caregiver-reported (0.86; 0.91) scores. Construct validity was supported by monotone decreasing relationships between the mean of SymTrak total scores across the poor-to-excellent categories of physical and emotional general health, and by high correlations with HUI3 overall utility score, even after adjusting for demographic covariates (standardized linear regression coefficient = - 0.84 for patients; - 0.70 for caregivers). Three-month change in the SymTrak total score was sensitive to detecting criterion standard 3-month reliable change categories (Improved, Stable, Declined) in HUI3-based health-related quality of life, especially for caregiver-reported scores. CONCLUSIONS: SymTrak demonstrates good internal consistency and test-retest reliability, construct validity, and sensitivity to change over a 3-month period, supporting its use for monitoring symptoms for older adults with MCCs.

Development and Feasibility of SymTrak, aMulti-domain Tool for Monitoring Symptoms of Older Adults in Primary Care.

BACKGROUND: A clinically practical, brief, user-friendly, multi-domain self-report and caregiver-report tool is needed for tracking actionable symptoms in primary care for elderly patients with multiple chronic conditions (MCCs). OBJECTIVE: Develop and assess usability, administration time, and internal reliability of SymTrak. DESIGN AND PARTICIPANTS: Phase I: legacy instruments, content validity, analyses of existing data, focus groups (physicians, nurses, patients, informal caregivers), and Think Aloud interviews (patients, caregivers) were used to develop SymTrak. Phase II (pilot feasibility study): 81 (27 patient-caregiver dyads, 27 patients without an identified caregiver) participants were self-administered SymTrak in clinic. MAIN MEASURES: SymTrak and demographic questions. KEY RESULTS: Consistent themes emerged from phase I focus groups. Ambiguous wording was corrected with Think Aloud feedback. In phase II, patients and caregivers preferred circling words instead of numbers for item response options. SymTrak self-administration completion time in clinic was brief; mean was 2.4, 3.0, and 3.3 min for the finalized circlingwords version, respectively, for caregivers, dyadic patients, and patients without a caregiver; and the maximum was 6.2 min for any participant. Usability questionnaire ratings were high. Cronbach's alpha for the SymTrak 23-item total score was 0.86, 0.79, and 0.81 for caregivers, dyadic patients, and patients without a caregiver, respectively. CONCLUSIONS: SymTrak demonstrates content validity, positive qualitative findings, high perceived usability, brief self-administered completion time, and good internal reliability.

Incorporating PROMIS Symptom Measures into Primary Care Practice-a Randomized Clinical Trial.

BACKGROUND: Symptoms account for more than 400 million clinic visits annually in the USA. The SPADE symptoms (sleep, pain, anxiety, depression, and low energy/fatigue) are particularly prevalent and undertreated. OBJECTIVE: To assess the effectiveness of providing PROMIS (Patient-Reported Outcome Measure Information System) symptom scores to clinicians on symptom outcomes. DESIGN: Randomized clinical trial conducted from March 2015 through May 2016 in general internal medicine and family practice clinics in an academic healthcare system. PARTICIPANTS: Primary care patients who screened positive for at least one SPADE symptom. INTERVENTIONS: After completing the PROMIS symptom measures electronically immediately prior to their visit, the 300 study participants were randomized to a feedback group in which their clinician received a visual display of symptom scores or a control group in which scores were not provided to clinicians. MAIN MEASURES: The primary outcome was the 3-month change in composite SPADE score. Secondary outcomes were individual symptom scores, symptom documentation in the clinic note, symptom-specific clinician actions, and patient satisfaction. KEY RESULTS: Most patients (84%) had multiple clinically significant (T-score ≥ 55) SPADE symptoms. Both groups demonstrated moderate symptom improvement with a non-significant trend favoring the feedback compared to control group (between-group difference in composite T-score improvement, 1.1; P = 0.17). Symptoms present at baseline resolved at 3-month follow-up only one third of the time, and patients frequently still desired treatment. Except for pain, clinically significant symptoms were documented less than half the time. Neither symptom documentation, symptom-specific clinician actions, nor patient satisfaction differed between treatment arms. Predictors of greater symptom improvement included female sex, black race, fewer medical conditions, and receiving care in a family medicine clinic. CONCLUSIONS: Simple feedback of symptom scores to primary care clinicians in the absence of additional systems support or incentives is not superior to usual care in improving symptom outcomes. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT02383862.

Rasch Analysis, Dimensionality, and Scoring of the Neuropsychiatric Inventory Irritability and Aggression Subscales in Individuals With Traumatic Brain Injury.

OBJECTIVES: To develop, for versions completed by individuals with traumatic brain injury (TBI) and an observer, a more precise metric for the Neuropsychiatric Inventory (NPI) Irritability and Aggression subscales using all behavioral item ratings for use with individuals with TBI and to address the dimensionality of the represented behavioral domains. DESIGN: Rasch and confirmatory factor analyses of retrospective baseline NPI data from 3 treatment studies. SETTING: Postacute rehabilitation clinic. PARTICIPANTS: NPI records (N = 525) consisting of observer ratings (n = 287) and self-ratings (n = 238) by participants with complicated mild, moderate, or severe TBI at least 6 months postinjury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Frequency and severity ratings from NPI Irritability/Lability and Agitation/Aggression subscales. RESULTS: Confirmatory factor analyses of both observer and participant ratings showed good fit for either a 1-factor or a 2-factor solution. Consistent with this, the Rasch model also fit the data well with aggression items indicating the more severe end of the construct and irritability items populating the milder end. CONCLUSIONS: Irritability and aggression appear to represent different levels of severity of a single construct. The derived Rasch metric offers a measure of this construct based on responses to all specific items that is appropriate for parametric statistical analysis and may be useful in research and clinical assessments of individuals with TBI.

Does a Crossover Age Effect Exist for African American and Hispanic Binge Drinkers? Findings from the 2010 to 2013 National Study on Drug Use and Health.

BACKGROUND: Among general population studies, lower rates of binge drinking tend to be found among African Americans and Hispanics compared to Whites. However, among older adult populations, minority groups have been shown to be at higher risk for binge drinking, suggesting the presence of a crossover effect from low to high risk as a function of age. To date, limited research has examined the crossover effect among African American and Hispanic populations compared to non-Hispanic Whites across large developmental time frames or explored variation in risk based on income or gender. This study aimed to fill these gaps in the literature. METHODS: Data were compiled from the 2010 to 2013 National Survey on Drug Use and Health surveys, which provide annual, nationally representative data on substance use behaviors among individuals aged 12 and older. Hispanic, non-Hispanic African American, and non-Hispanic White respondents were included (N = 205,198) in the analyses. RESULTS: A crossover effect was found for African American males and females among the lowest income level (i.e., incomes less than $20,000). Specifically, after controlling for education and marital status, compared to Whites, risk for binge drinking was lower for African American males at ages 18 to 24 and for females at ages 18 to 34, but higher for both African American males and females at ages 50 to 64. No crossover effect was found for Hispanic respondents. CONCLUSIONS: Although African Americans are generally at lower risk for binge drinking, risk appears to increase disproportionately with age among those who are impoverished. Explanatory factors, such as social determinants of health prevalent within low-income African American communities (e.g., lower education, violence exposure, housing insecurity) and potential areas for intervention programming are discussed.
