Item Assessing Depression Improvement with the Remission Evaluation and Mood Inventory Tool (REMIT)(Elsevier, 2019-09) Bushey, Michael A.; Kroenke, Kurt; Baye, Fitsum; Lourens, Spencer; Psychiatry, School of MedicineObjective The Remission Evaluation and Mood Inventory Tool (REMIT) was developed as a brief complementary measure to provide a more robust assessment of depression improvement than tracking DSM-V symptom improvement alone. This study provides further validation of the REMIT tool and examines its utility in predicting depression improvement. Methods The sample comprised 294 primary care patients enrolled in a telecare trial of pain plus depression and/or anxiety. Assessments collected included: REMIT, PHQ-9 and measures assessing anxiety, pain, sleep, fatigue, somatization, health-related quality of life and disability. Data was analyzed to assess the REMIT's validity, its minimally important difference (MID), and its utility in predicting 6-month depression improvement. Results Convergent and construct validity of REMIT was supported by moderate correlations with mental health measures and weaker correlation with physical health measures. MID of approximately 2 points for REMIT was estimated by two metrics: 0.5 standard deviation and 1 standard error of measurement. Both baseline and 3-month change in REMIT scores predicted depression improvement at 6 months. Indeed, REMIT was as good or better predictor than the PHQ-9. Conclusion The REMIT measure is a brief 5-item tool that augments core DSM-V symptom-oriented metrics in assessing and predicting recovery from major depression.Item Automated Self-management (ASM) vs. ASM-Enhanced Collaborative Care for Chronic Pain and Mood Symptoms: the CAMMPS Randomized Clinical Trial(Springer, 2019-06-21) Kroenke, Kurt; Baye, Fitsum; Lourens, Spencer G.; Evans, Erica; Weitlauf, Sharon; McCalley, Stephanie; Porter, Brian; Matthias, Marianne S.; Bair, Matthew J.; Medicine, School of MedicineBackground Chronic musculoskeletal pain is often accompanied by depression or anxiety wherein co-occurring pain and mood symptoms can be more difficult to treat than either alone. However, few clinical trials have examined interventions that simultaneously target both pain and mood conditions. Objective To determine the comparative effectiveness of automated self-management (ASM) vs. ASM-enhanced collaborative care. Design Randomized clinical trial conducted in six primary care clinics in a VA medical center. Participants Two hundred ninety-four patients with chronic musculoskeletal pain of at least moderate intensity and clinically significant depressive and/or anxiety symptoms. Intervention ASM consisted of automated monitoring and 9 web-based self-management modules. Comprehensive symptom management (CSM) combined ASM with collaborative care management by a nurse-physician team. Both interventions were delivered for 12 months. Main Measures Primary outcome was a composite pain-anxiety-depression (PAD) z-score consisting of the mean of the BPI, PHQ-9, and GAD-7 z-scores: 0.2, 0.5, and 0.8 represent potentially small, moderate, and large clinical differences. Secondary outcomes included global improvement, health-related quality of life, treatment satisfaction, and health services use. Key Results Both CSM and ASM groups had moderate PAD score improvement at 12 months (z = − 0.65 and − 0.52, respectively). Compared to the ASM group, the CSM group had a − 0.23 (95% CI, − 0.38 to − 0.08; overall P = .003) greater decline in composite PAD z-score over 12 months. CSM patients were also more likely to report global improvement and less likely to report worsening at 6 (P = .004) and 12 months (P = .013). Conclusions Two intervention models relying heavily on telecare delivery but differing in resource intensity both produced moderate improvements in pain and mood symptoms. However, the model combining collaborative care led by a nurse-physician team with web-based self-management was superior to self-management alone.Item Barriers and facilitators to provide quality TIA care in the Veterans Healthcare Administration(American Academy of Neurology, 2017-12-12) Damush, Teresa M.; Miech, Edward J.; Sico, Jason J.; Phipps, Michael S.; Arling, Greg; Ferguson, Jared; Austin, Charles; Myers, Laura; Baye, Fitsum; Luckhurst, Cherie; Keating, Ava B.; Moran, Eileen; Bravata, Dawn M.; Medicine, School of MedicineObjective: To identify key barriers and facilitators to the delivery of guideline-based care of patients with TIA in the national Veterans Health Administration (VHA). Methods: We conducted a cross-sectional, observational study of 70 audiotaped interviews of multidisciplinary clinical staff involved in TIA care at 14 VHA hospitals. We de-identified and analyzed all transcribed interviews. We identified emergent themes and patterns of barriers to providing TIA care and of facilitators applied to overcome these barriers. Results: Identified barriers to providing timely acute and follow-up TIA care included difficulties accessing brain imaging, a constantly rotating pool of housestaff, lack of care coordination, resource constraints, and inadequate staff education. Key informants revealed that both stroke nurse coordinators and system-level factors facilitated the provision of TIA care. Few facilities had specific TIA protocols. However, stroke nurse coordinators often expanded upon their role to include TIA. They facilitated TIA care by (1) coordinating patient care across services, communicating across service lines, and educating clinical staff about facility policies and evidence-based practices; (2) tracking individual patients from emergency departments to inpatient settings and to discharge for timely follow-up care; (3) providing and referring TIA patients to risk factor management programs; and (4) performing regular audit and feedback of quality performance data. System-level facilitators included clinical service leadership engagement and use of electronic tools for continuous care across services. Conclusions: The local organization within a health care facility may be targeted to cultivate internal facilitators and a systemic infrastructure to provide evidence-based TIA care.Item Comparing the Patient Health Questionnaire – 15 and the Somatic Symptom Scale – 8 as measures of somatic symptom burden(Elsevier, 2017-10) Toussaint, Anne; Kroenke, Kurt; Baye, Fitsum; Lourens, Spencer; Department of Medicine, School of MedicinePurpose The Patient Health Questionnaire – 15 (PHQ-15) and the Somatic Symptom Scale – 8 (SSS-8) are self-report measures which assess somatic symptom burden. The present study investigates whether the two measures are comparable in terms of their psychometric properties and estimates of symptom burden. Method Item characteristics, reliability, symptom severity and construct validity with regard to other relevant psychological, health-related quality of life and disability measures were compared for the PHQ-15m and the SSS-8 in 294 primary care patients who participated in a randomized comparative effectiveness trial targeting pain and mood symptoms. Results The reliabilities of the PHQ-15m and the SSS-8 were α = 0.66 and α = 0.72, respectively. Both measures were highly correlated (r = 0.79). All item characteristics were comparable and both instruments showed the same pattern of correlations with instruments measuring depression, anxiety, pain, quality of life and impairment (r = 0.25 to 0.53). A 1-point score increase (worsening of somatic symptoms) on either instrument resulted in a 3.7% to 3.9% increase in the number of disability days reported for the last four weeks. Using the same severity thresholds (5: low, 10: medium, 15: high), both measures identified nearly identical subgroups of patients with regard to health-related quality of life and disability. Conclusion The PHQ-15m and the SSS-8 are comparable measures in terms of reliability and validity and severity classifications. These findings are in line with previous results and support the use of the SSS-8 as a valuable and short alternative to the original PHQ-15 in settings with limited assessment time.Item Comparison of Risk Factor Control in the Year After Discharge for Ischemic Stroke Versus Acute Myocardial Infarction(American Heart Association, 2018-02) Bravata, Dawn M.; Daggy, Joanne; Brosch, Jared; Sico, Jason J.; Baye, Fitsum; Myers, Laura J.; Roumie, Christianne L.; Cheng, Eric; Coffing, Jessica; Arling, Greg; Medicine, School of MedicineBACKGROUND AND PURPOSE: The Veterans Health Administration has engaged in quality improvement to improve vascular risk factor control. We sought to examine blood pressure (<140/90 mm Hg), lipid (LDL [low-density lipoprotein] cholesterol <100 mg/dL), and glycemic control (hemoglobin A1c <9%), in the year post-hospitalization for acute ischemic stroke or acute myocardial infarction (AMI). METHODS: We identified patients who were hospitalized (fiscal year 2011) with ischemic stroke, AMI, congestive heart failure, transient ischemic attack, or pneumonia/chronic obstructive pulmonary disease. The primary analysis compared risk factor control after incident ischemic stroke versus AMI. Facilities were included if they cared for ≥25 ischemic stroke and ≥25 AMI patients. A generalized linear mixed model including patient- and facility-level covariates compared risk factor control across diagnoses. RESULTS: Forty thousand two hundred thirty patients were hospitalized (n=75 facilities): 2127 with incident ischemic stroke and 4169 with incident AMI. Fewer stroke patients achieved blood pressure control than AMI patients (64%; 95% confidence interval, 0.62-0.67 versus 77%; 95% confidence interval, 0.75-0.78; P<0.0001). After adjusting for patient and facility covariates, the odds of blood pressure control were still higher for AMI than ischemic stroke patients (odds ratio, 1.39; 95% confidence interval, 1.21-1.51). There were no statistical differences for AMI versus stroke patients in hyperlipidemia (P=0.534). Among patients with diabetes mellitus, the odds of glycemic control were lower for AMI than ischemic stroke patients (odds ratio, 0.72; 95% confidence interval, 0.54-0.96). CONCLUSIONS: Given that hypertension control is a cornerstone of stroke prevention, interventions to improve poststroke hypertension management are neededItem Composite measures of pain, anxiety, and depressive (PAD) symptoms: Construct and predictive validity(Elsevier, 2021-09) Bushey, Michael A.; Kroenke, Kurt; Baye, Fitsum; Lourens, Spencer; Psychiatry, School of MedicineObjective Pain, anxiety, and depression (PAD) are common, co-occurring symptoms that adversely affect one another and may respond to common treatments. PAD composite measures would be useful for tracking treatment response in patients with PAD symptoms. The goal of this study is to compare 3 different PAD composite scales in terms of construct validity, responsiveness, and utility in predicting global improvement. Method The sample consisted of 294 primary care patients enrolled in a telecare trial for treating pain, anxiety, and depression. Assessments at baseline and 3 months included the Brief Pain Inventory, PHQ-9 depression scale, GAD-7 anxiety scale, PROMIS measures, Medical Outcomes Study Short-Form items, disability measures, and patient-reported global improvement. Construct validity of the PAD composite measures, their responsiveness, and their ability to predict global improvement was analyzed using Pearson correlations, standardized response means, and receiver operating characteristics analysis. Results PAD composite measures correlated strongly with one another, and moderately with measures of function, vitality, and disability. Each PAD composite measure demonstrated similar responsiveness in detecting improvement at 3 months as assessed by standardized response means (SRMs) and area under the curve (AUC analyses).The SRMs for partial and substantial global improvement corresponded to moderate (Cohen's d of 0.58 to 0.69) and large (0.81 to 0.93) effect sizes, respectively. Conclusions Three different PAD composite measures demonstrate good construct validity as well as responsiveness in detecting global improvement of pain, anxiety and depression at 3 months.Item Comprehensive vs. Assisted Management of Mood and Pain Symptoms (CAMMPS) trial: Study design and sample characteristics(Elsevier, 2017) Kroenke, Kurt; Evans, Erica; Weitlauf, Sharon; McCalley, Stephanie; Porter, Brian; Williams, Tabeel; Baye, Fitsum; Lourens, Spencer G.; Matthias, Marianne S.; Bair, Matthew J.; Medicine, School of MedicineBackground Pain is the most common presenting somatic symptom in medical outpatients, and depression and anxiety are the two most common mental disorders. They frequently co-occur, are under-treated, and result in substantial disability and reduced health-related quality of life. Objectives The Comprehensive vs. Assisted Management of Mood and Pain Symptoms (CAMMPS) study is a randomized comparative effectiveness trial designed to test the relative effectiveness of a lower-resource vs. a higher-resource technology-assisted intervention for the management of patients suffering from pain plus anxiety and/or depression. Methods/design CAMMPS has enrolled 294 primary care patients with chronic pain plus comorbid anxiety and/or depression and randomized them to either: 1) Assisted Symptom Management (ASM) consisting of automated symptom monitoring by interactive voice recording or Internet and prompted pain and mood self-management; or 2) Comprehensive Symptom Management (CSM) which combines ASM with optimized medication management delivered by a nurse-physician specialist team and facilitated mental health care. Outcomes are assessed at baseline, 1, 3, 6, and 12 months. The primary outcome is a composite pain-anxiety-depression (PAD) severity score. Secondary outcomes include individual pain, anxiety, and depression scores, health-related quality of life, disability, healthcare utilization, and treatment satisfaction. Discussion CAMMPS provides an integrated approach to PAD symptoms rather than fragmented care of single symptoms; coordinated symptom management in partnership with primary care clinicians and psychologists embedded in primary care; efficient use of health information technology; attention to physical and psychological symptom comorbidity; and the coupling of self-management with optimized medication management and facilitated mental health care.Item Development and Validation of Electronic Quality Measures to Assess Care for Patients With Transient Ischemic Attack and Minor Ischemic Stroke(AHA, 2017) Bravata, Dawn M.; Myers, Laura J.; Cheng, Eric; Reeves, Mathew; Baye, Fitsum; Zhangsheng, Yu; Damush, Teresa; Miech, Edward J.; Sico, Jason; Phipps, Michael; Zillich, Alan; Johanning, Jason; Chaturvedi, Seemant; Austin, Curt; Ferguson, Jared; Maryfield, Bailey; Snow, Kathy; Ofner, Susan; Graham, Glenn; Rhude, Rachel; Williams, Linda S.; Arling, Greg; Medicine, School of MedicineBackground—Despite interest in using electronic health record (EHR) data to assess quality of care, the accuracy of such data is largely unknown. We sought to develop and validate transient ischemic attack and minor ischemic stroke electronic quality measures (eQMs) using EHR data. Methods and Results—A random sample of patients with transient ischemic attack or minor ischemic stroke, cared for in Veterans Health Administration facilities (fiscal year 2011), was identified. We constructed 31 eQMs based on existing quality measures. Chart review was the criterion standard for validating the eQMs. To evaluate eQMs in terms of eligibility, we calculated the proportion of patients who were genuinely not eligible to receive a process (based on chart review) and who were correctly identified as not eligible by the EHR data (specificity). To assess eQMs about classification of whether patients received a process, we calculated the proportion of patients who actually received the process (based on chart review) and who were classified correctly by the EHR data as passing (sensitivity). Seven hundred sixty-three patients were included. About eligibility, specificity varied from 25% (brain imaging; carotid imaging) to 99% (anticoagulation quality). About pass rates, sensitivity varied from 30% (antihypertensive class) to 100% (coronary risk assessment; international normalized ratio measured). The 16 eQMs with ≥70% specificity in eligibility and ≥70% sensitivity in pass rates included coronary risk assessment, international normalized ratio measured, HbA1c measurement, speech language pathology consultation, anticoagulation for atrial fibrillation, discharge on statin, lipid management, neurology consultation, Holter, deep vein thrombosis prophylaxis, oral hypoglycemic intensification, cholesterol medication intensification, antihypertensive intensification, antihypertensive class, carotid stenosis intervention, and substance abuse referral for alcohol. Conclusions—It is feasible to construct valid eQMs for processes of transient ischemic attack and minor ischemic stroke care. Healthcare systems with EHRs should consider using electronic data to evaluate care for their patients with transient ischemic attack and to complement and expand quality measurement programs currently focused on patients with stroke.Item Gene expression profiles among murine strains segregate with distinct differences in the progression of radiation-induced lung disease(The Company of Biologists, 2017-04-01) Jackson, Isabel L.; Baye, Fitsum; Goswami, Chirayu P.; Katz, Barry P.; Zodda, Andrew; Pavlovic, Radmila; Gurung, Ganga; Winans, Don; Vujaskovic, Zeljko; Biostatistics, School of Public HealthMolecular mechanisms underlying development of acute pneumonitis and/or late fibrosis following thoracic irradiation remain poorly understood. Here, we hypothesize that heterogeneity in disease progression and phenotypic expression of radiation-induced lung disease (RILD) across murine strains presents an opportunity to better elucidate mechanisms driving tissue response toward pneumonitis and/or fibrosis. Distinct differences in disease progression were observed in age- and sex-matched CBA/J, C57L/J and C57BL/6J mice over 1 year after graded doses of whole-thorax lung irradiation (WTLI). Separately, comparison of gene expression profiles in lung tissue 24 h post-exposure demonstrated >5000 genes to be differentially expressed (P<0.01; >twofold change) between strains with early versus late onset of disease. An immediate divergence in early tissue response between radiation-sensitive and -resistant strains was observed. In pneumonitis-prone C57L/J mice, differentially expressed genes were enriched in proinflammatory pathways, whereas in fibrosis-prone C57BL/6J mice, genes were enriched in pathways involved in purine and pyrimidine synthesis, DNA replication and cell division. At 24 h post-WTLI, different patterns of cellular damage were observed at the ultrastructural level among strains but microscopic damage was not yet evident under light microscopy. These data point toward a fundamental difference in patterns of early pulmonary tissue response to WTLI, consistent with the macroscopic expression of injury manifesting weeks to months after exposure. Understanding the mechanisms underlying development of RILD might lead to more rational selection of therapeutic interventions to mitigate healthy tissue damage.Item Have clinicians adopted the use of brain MRI for patients with TIA and minor stroke?(American Academy of Neurology, 2017-01-17) Chaturvedi, Seemant; Ofner, Susan; Baye, Fitsum; Myers, Laura J.; Phipps, Mike; Sico, Jason J.; Damush, Teresa; Miec, Edward; Reeves, Mat; Johanning, Jason; Williams, Linda S.; Arling, Greg; Cheng, Eric; Yu, Zhangsheng; Bravata, Dawn; Biostatistics, School of Public HealthBACKGROUND: Use of MRI with diffusion-weighted imaging (DWI) can identify infarcts in 30%-50% of patients with TIA. Previous guidelines have indicated that MRI-DWI is the preferred imaging modality for patients with TIA. We assessed the frequency of MRI utilization and predictors of MRI performance. METHODS: A review of TIA and minor stroke patients evaluated at Veterans Affairs hospitals was conducted with regard to medical history, use of diagnostic imaging within 2 days of presentation, and in-hospital care variables. Chart abstraction was performed in a subset of hospitals to assess clinical variables not available in the administrative data. RESULTS: A total of 7,889 patients with TIA/minor stroke were included. Overall, 6,694 patients (84.9%) had CT or MRI, with 3,396/6,694 (50.7%) having MRI. Variables that were associated with increased odds of CT performance were age >80 years, prior stroke, history of atrial fibrillation, heart failure, coronary artery disease, anxiety, and low hospital complexity, while blood pressure >140/90 mm Hg and high hospital complexity were associated with increased likelihood of MRI. Diplopia (87% had MRI, p = 0.03), neurologic consultation on the day of presentation (73% had MRI, p < 0.0001), and symptom duration of >6 hours (74% had MRI, p = 0.0009) were associated with MRI performance. CONCLUSIONS: Within a national health system, about 40% of patients with TIA/minor stroke had MRI performed within 2 days. Performance of MRI appeared to be influenced by several patient and facility-level variables, suggesting that there has been partial acceptance of the previous guideline that endorsed MRI for patients with TIA.
