Acceptance of a Risk Estimation Tool for Colorectal Cancer Screening
(Office of the Vice Chancellor for Research, 2016-04-08) Luckhurst, Cherie; Imperiale, Tom; Matthias, Marianne S.
Abstract: While colonoscopy is the most prevalent screening test for colorectal cancer (CRC), it is often too expensive, too uncomfortable, or too time-consuming for patients. Non-compliance is common. Recently, fecal immunochemical testing (FIT) has become a guideline-recommended alternative. The FIT is a non-invasive, inexpensive method that requires no uncomfortable preparation by patients. The decision to recommend the colonoscopy or the FIT is based on the patient’s estimated risk for CRC. Several countries have created risk prediction tools to help identify patients at high risk for advanced colorectal neoplasia (the combination of CRC and advanced, precancerous polyps). A U.S.-based prediction tool was recently published1 that uses five easily and reliably measured factors (age, sex, a first degree relative with CRC, waist circumference, and cigarette smoking history) to quantify risk. We aimed to learn the impressions of clinicians and patients to this risk estimation tool. In the first phase of this study, we used a semi-structured format to interview clinicians at a VA medical center and a non-VA hospital. Using a paper prototype of the risk estimation tool, we asked about its usefulness to estimate risk and to aid their selection of a CRC screening tool. Using a grounded theory approach, we analyzed the interview transcripts and identified major themes. We found that clinicians thought the tool was clear and easy to use. However, they are unlikely to use it as a decision aid until FIT is more widely-endorsed as an acceptable alternative screening test. In phase two of the study, we will interview patients to assess their responses to the tool.

(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 Medicine
Background 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.
Barriers to guideline-concordant antibiotic use among inpatient physicians: A case vignette qualitative study
(Wiley, 2016-03) Livorsi, D.; Comer, Amber R.; Matthias, Marianne S.; Perencevich, E.N.; Bair, M.J.; Department of Communication Studies, School of Liberal Arts
BACKGROUND: Greater adherence to antibiotic-prescribing guidelines may promote more judicious antibiotic use, which could benefit individual patients and society at large. OBJECTIVE: To assess physician knowledge and acceptance of antibiotic-prescribing guidelines through the use of case vignettes. DESIGN: We conducted semistructured interviews with 30 inpatient physicians. Participants were asked to respond to 3 hypothetical case vignettes: (1) a skin and soft tissue infection (SSTI), (2) suspected hospital-acquired pneumonia (HAP), and (3) asymptomatic bacteriuria (ASB). All participants received feedback according to guidelines from the Infectious Diseases Society of America (IDSA) and were asked to discuss their level of comfort with following these guidelines. SETTING: Two acute care teaching hospitals for adult patients. INTERVENTION: None. MEASUREMENTS: Data from transcribed interviews were analyzed using emergent thematic analysis. RESULTS: Participants were receptive to guidelines and believed they were useful. However, participants' responses to the case vignettes demonstrated that IDSA guideline recommendations were not routinely followed for SSTI, HAP, and ASB. We identified 3 barriers to guideline-concordant care: (1) physicians' lack of awareness of specific guideline recommendations; (2) tension between adhering to guidelines and the desire to individualize patient care; and (3) skepticism of certain guideline recommendations. CONCLUSIONS: Case vignettes may be useful tools to assess physician knowledge and acceptance of antibiotic-prescribing guidelines. Using case vignettes, we identified 3 barriers to following IDSA guidelines. Efforts to improve guideline-concordant antibiotic prescribing should focus on reducing such barriers at the local level.
A Brief Peer Support Intervention for Veterans with Chronic Musculoskeletal Pain: A Pilot Study of Feasibility and Effectiveness
(Wiley, 2015-01) Matthias, Marianne S.; McGuire, Alan B.; Kukla, Marina; Daggy, Joanne; Myers, Laura J.; Bair, Matthew J.; Department of Communication Studies, School of Liberal Arts
Objective The aim of this study was to pilot test a peer support intervention, involving peer delivery of pain self-management strategies, for veterans with chronic musculoskeletal pain. Design Pretest/posttest with 4-month intervention period. Methods Ten peer coaches were each assigned 2 patients (N = 20 patients). All had chronic musculoskeletal pain. Guided by a study manual, peer coach–patient pairs were instructed to talk biweekly for 4 months. Pain was the primary outcome and was assessed with the PEG, a three-item version of the Brief Pain Inventory, and the PROMIS Pain Interference Questionnaire. Several secondary outcomes were also assessed. To assess change in outcomes, a linear mixed model with a random effect for peer coaches was applied. Results Nine peer coaches and 17 patients completed the study. All were male veterans. Patients' pain improved at 4 months compared with baseline but did not reach statistical significance (PEG: P = 0.33, ICC [intra-class correlation] = 0.28, Cohen's d = −0.25; PROMIS: P = 0.17, d = −0.35). Of secondary outcomes, self-efficacy (P = 0.16, ICC = 0.56, d = 0.60) and pain centrality (P = 0.06, ICC = 0.32, d = −0.62) showed greatest improvement, with moderate effect sizes. Conclusions This study suggests that peers can effectively deliver pain self-management strategies to other veterans with pain. Although this was a pilot study with a relatively short intervention period, patients improved on several outcomes.
Circumstances and consequences of falls among people with chronic stroke
(2013) Schmid, Arlene A.; Yaggi, H. Klar; Burrus, Nicholas; McClain, Vincent; Austin, Charles; Ferguson, Jared; Fragoso, Carlos; Sico, Jason J.; Miech, Edward J.; Matthias, Marianne S.; Williams, Linda S.; Bravata, Dawn M.
Falls are common after stroke; however, circumstances and consequences are relatively unknown. Our objectives were to identify the differences between fallers and non-fallers among people with chronic stroke, identify the circumstances of fall events, and examine the consequences of the falls. This is a secondary data analysis; all participants included sustained a stroke. Variables included demographics, stroke characteristics, and comorbidities. Falls were collected via self-report, and circumstances and consequences were derived from participant description of the event and categorized as appropriate. Among 160 participants, 53 (33%) reported a fall during the 1 yr period. Circumstances of falls were categorized as intrinsic or extrinsic. Location and circumstance of the fall were included: 70% occurred at home and 40% were associated with impaired physical or mental state (e.g., inattention to tying shoes). Additionally, 21% of falls were associated with activities of daily living and mobility and 34% with slips or trips. The majority who fell sustained an injury (72%). Injuries ranged from bruising to fractures, and 55% of those with an injury sought medical care (32% to emergency department). Poststroke falls are associated with an alarming rate of injury and healthcare utilization. Targeting mental and physical states may be key to fall prevention.
A Coding System to Measure Elements of Shared Decision Making During Psychiatric Visits
(2012-08) Salyers, Michelle P.; Matthias, Marianne S.; Fukui, Sadaaki; Holter, Mark C.; Collins, Linda; Rose, Nichole; Thompson, John; Coffman, Melinda; Torrey, William C.
Objective: Shared decision making is widely recognized to facilitate effective health care. The purpose of this study was to assess the applicability and usefulness of a scale to measure the presence and extent of shared decision making in clinical decisions in psychiatric practice. Methods: A coding scheme assessing shared decision making in general medical settings was adapted to mental health settings, and a manual for using the scheme was created. Trained raters used the adapted scale to analyze 170 audio-recordings of medication check-up visits with either psychiatrists or nurse practitioners. The scale assessed the level of shared decision making based on the presence of nine specific elements. Interrater reliability was examined, and the frequency with which elements of shared decision making were observed was documented. The association between visit length and extent of shared decision making was also examined. Results: Interrater reliability among three raters on a subset of 20 recordings ranged from 67% to 100% agreement for the presence of each of the nine elements of shared decision making and 100% for the agreement between provider and consumer on decisions made. Of the 170 sessions, 128 (75%) included a clinical decision. Just over half of the decisions (53%) met minimum criteria for shared decision making. Shared decision making was not related to visit length after the analysis controlled for the complexity of the decision. Conclusions: The rating scale appears to reliably assess shared decision making in psychiatric practice and could be helpful for future research, training, and implementation efforts.
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 Medicine
Background 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.
Consumer and Relationship Factors Associated with Shared Decision-Making in Mental Health Consultations
(2014-12) Matthias, Marianne S.; Fukui, Sadaaki; Kukla, Marina; Eliacin, Johanne; Bonfils, Kelsey A.; Firmin, Ruth; Oles, Sylwia; Adams, Erin L.; Collins, Linda A.; Salyers, Michelle P.; Department of Psychology, IU School of Science
Objective: This study explored the association between shared decision making and consumers’ illness management skills and consumer-provider relationships. Methods: Medication management appointments for 79 consumers were audio recorded. Independent coders rated overall shared decision making, minimum level of shared decision making, and consumer-provider agreement for 63 clients whose visit included a treatment decision. Mental health diagnoses, medication adherence, patient activation, illness management, working alliance, and length of consumer-provider relationships were also assessed. Correlation analyses were used to determine relationships among measures. Results: Overall shared decision making was not associated with any variables. Minimum levels of shared decision making were associated with higher scores on the bond subscale of the Working Alliance Inventory, indicating a higher degree of liking and trust, and with better medication adherence. Agreement was associated with shorter consumer-provider relationships. Conclusions: Consumer-provider relationships and shared decision making might have a more nuanced association than originally thought.
Core domains of shared decision-making during psychiatric visits: scientific and preference-based discussions
(Springer, 2015-01) Fukui, Sadaaki; Matthias, Marianne S.; Salyers, Michelle P.; Department of Psychology, School of Science
Shared decision-making (SDM) is imperative to person-centered care, yet little is known about what aspects of SDM are targeted during psychiatric visits. This secondary data analysis (191 psychiatric visits with 11 providers, coded with a validated SDM coding system) revealed two factors (scientific and preference-based discussions) underlying SDM communication. Preference-based discussion occurred less. Both provider and consumer initiation of SDM elements and decision complexity were associated with greater discussions in both factors, but were more strongly associated with scientific discussion. Longer visit length correlated with only scientific discussion. Providers' understanding of core domains could facilitate engaging consumers in SDM.
