Abstract
BACKGROUND Whether disclosure of a genetic risk score (GRS) for a common disease influences relevant clinical outcomes is unknown. We describe design of the Myocardial Infarction Genes (MI-GENES) Study, a randomized clinical trial to assess whether disclosing a GRS for coronary heart disease (CHD) leads to lowering of low-density lipoprotein cholesterol (LDL-C) levels. METHODS AND DESIGN We performed an initial screening genotyping of 28 CHD susceptibility single-nucleotide polymorphisms (SNPs) that are not associated with blood pressure or lipid levels, in 1000 individuals from Olmsted County, Minnesota who were participants in the Mayo Clinic BioBank and met eligibility criteria. We calculated GRS based on 28 SNPs and will enroll 110 patients each in two CHD genomic risk categories: high (GRS ≥1.1), and average/low (GRS <1.1). The study coordinator will obtain informed consent for the study that includes placing genetic testing results in the electronic health record. Participants will undergo a blood draw and return 6-10 weeks later (Visit 2) once genotyping is completed and a GRS calculated. At this visit, patients will be randomized (1:1) to receive CHD risk estimates from a genetic counselor based on a conventional risk score (CRS) vs. GRS, followed by shared decision making with a physician regarding statin use. Three and six months following the disclosure of CHD risk, participants will return for measurement of fasting lipid levels and assessment of changes in dietary fat intake and physical activity levels. Psychosocial measures will be assessed at baseline and after disclosure of CHD risk. DISCUSSION The proposed trial will provide insights into the clinical utility of genetic testing for CHD risk assessment.

Abstract
BACKGROUND Very low quality (VLQ) evidence translates into very low confidence in the balance of risk and benefits based on the estimates drawn from the body of evidence. Consequently, this assessment highlights gaps in the research evidence, i.e. knowledge gaps, for important clinical questions. In this way, expert guideline panels identify priority knowledge gaps that, arguably, should inform the research agenda and prioritize scarce research economical resources. The extent to which the research agenda reflects the knowledge gaps identified in clinical practice guidelines is unknown. METHODS A systematic evaluation of the Endocrine Society (ES) clinical practice guidelines portfolio from 2008 to 2014 was conducted with the objectives to identify (1) recommendations in the ES clinical practice guidelines based on VLQ evidence reflecting knowledge gaps in endocrinology, and (2) active research designed to address these gaps by searching the clinical trial registry, clinicaltrials.gov, using terms describing patients (diseases), interventions, comparison, and outcomes. RESULTS In 25 ES guidelines, we found 660 recommendations, of which 131 (20 %) were supported by VLQ evidence. Clinical trialists are attempting to answer 28 (21 %) of these knowledge gaps by performing 69 clinical trials. CONCLUSION The research enterprise is addressing one in five knowledge gaps identified in clinical practice recommendations in endocrinology. These findings suggest an inefficiency in the allocation of very scarce research economical resources. Linking the research agenda to evidence gaps in clinical practice guidelines may improve both the efficiency of the research enterprise and the translation of evidence into more confident clinical practice.

Abstract
BACKGROUND Decision aids can increase patient involvement in decision-making about health care. The study goal was to develop and test a decision aid for use by clinicians in discussion options for changing smoking behavior before and after elective surgery. METHODS In formative work, a decision aid was designed to facilitate patient-clinician discussion regarding three options: continue smoking, attempt a period of temporary abstinence, and attempt to quit smoking for good. A randomized, two-group pilot study was then conducted in smokers evaluated in preparation for elective surgery in a preoperative clinic to test the hypothesis that the decision aid would improve measures of decisional quality compared with usual care. RESULTS The final decision aid consisted of three laminated cards. The front of each card included a colorful graphic describing each choice; the reverse including two to three pros and cons for each decision, a simple graphic illustrating the effects of smoking on the body, and a motivational phrase. In the randomized trial of 130 patients, the decision aid significantly (P < 0.05) improved measures of decisional quality and patient involvement in decision making (Cohen's d effect sizes of 0.76 and 1.20 for the Decisional Conflict Scale and Observing PatienT involvement In decisiON-making scale, respectively). However, the decision aid did not affect any aspect of perioperative smoking behavior, including the distribution of or adherence to choices. CONCLUSIONS Although the use of a decision aid to facilitate clinician-patient discussions regarding tobacco use around the time of surgery substantially improved measures of decisional quality, it alone did not change perioperative tobacco use behavior.

Abstract
PURPOSE Osteoporosis Choice, an encounter decision aid, can engage patients and clinicians in shared decision making about osteoporosis treatment. Its effectiveness compared to the routine provision to clinicians of the patient's estimated risk of fracture using the FRAX calculator is unknown. METHODS Patient-level, randomized, three-arm trial enrolling women over 50 with osteopenia or osteoporosis eligible for treatment with bisphosphonates, where the use of Osteoporosis Choice was compared to FRAX only and to usual care to determine impact on patient knowledge, decisional conflict, involvement in the decision-making process, decision to start and adherence to bisphosphonates. RESULTS We enrolled 79 women in the three arms. Because FRAX estimation alone and usual care produced similar results, we grouped them for analysis. Compared to these, use of Osteoporosis Choice increased patient knowledge (median score 6 vs. 4, p = .01), improved understanding of fracture risk and risk reduction with bisphosphonates (p = .01 and p<.0001, respectively), had no effect on decision conflict, and increased patient engagement in the decision making process (OPTION scores 57% vs. 43%, p = .001). Encounters with the decision aid were 0.8 minutes longer (range: 33 minutes shorter to 3.0 minutes longer). There were twice as many patients receiving and filling prescriptions in the decision aid arm (83% vs. 40%, p = .07); medication adherence at 6 months was no different across arms. CONCLUSION Supporting both patients and clinicians during the clinical encounter with the Osteoporosis Choice decision aid efficiently improves treatment decision making when compared to usual care with or without clinical decision support with FRAX results.

Abstract
BACKGROUND Management strategies for patients with chronic conditions are becoming increasingly complex, which may result in a burden of treatment for patients. To develop a Minimally Disruptive Medicine designed to reduce the burden of treatment, clinicians need to understand which healthcare tasks and aggravating factors may be responsible for this burden. The objective of the present study was to describe and classify the components of the burden of treatment for patients with chronic conditions from the patient's perspective. METHODS We performed a multi-country qualitative study using an online survey and a purposive sampling strategy to select English-, French-, and Spanish-speaking participants with different chronic conditions. Participants were recruited by physicians, patients' associations, advertisement on social media, and 'snowballing'. The answers were analyzed by i) manual content analysis with a grounded theory approach, coded by two researchers, and ii) automatic textual analysis by Reinert's method. RESULTS Between 2013 and 2014, 1,053 participants from 34 different countries completed the online survey using 408,625 words. Results from both analyses were synthesized in a taxonomy of the burden of treatment, which described i) the tasks imposed on patients by their diseases and by their healthcare system (e.g., medication management, lifestyle changes, follow-up, etc.); ii) the structural (e.g., access to healthcare resources, coordination between care providers), personal, situational, and financial factors that aggravated the burden of treatment; and iii) patient-reported consequences of the burden (e.g., poor adherence to treatments, financial burden, impact on professional, family, and social life, etc.). Our findings may not be applicable to patients with chronic conditions who differ from those who responded to our survey. CONCLUSIONS Our taxonomy of the burden of treatment, provided by patients with chronic conditions from different countries and settings, supports the development of tools to ascertain the burden of treatment and highlights potential targets for interventions to minimize it.

Abstract
OBJECTIVES Glycemic control can lower the risk of diabetes-related complications, and delayed treatment intensification can impede optimal diabetes care. This study examines trends in hyperglycemia treatment intensification between 2002 and 2010. STUDY DESIGN Retrospective secondary data analysis of a large national administrative data set of privately insured individuals across the United States. METHODS Adults 18 years or older with diabetes, initiated on metformin monotherapy between 2002 and 2007, were studied, stratified by date of first metformin prescription (2002-2003, 2004-2005, 2006-2007). Time to treatment intensification between 2002 and 2010, defined by the addition of ≥1 agents to metformin, was estimated using Kaplan-Meier and Cox proportional hazards regression analysis. RESULTS There were 75,069 treatment-naïve adults with diabetes first initiated on metformin between 2002 and 2007; mean age was 60 years (SD = 11.5), 49.7% were women, and 63.1% were non-Hispanic white. Diabetes therapy was intensified in 26,169 individuals (34.6%).Treatment intensification became increasingly more likely with time for the 2004-2005 cohort (hazard ratio [HR], 1.07; 95% CI, 1.04-1.10) and for the 2006-2007 cohort (HR, 1.11; 95% CI, 1.07-1.14) compared with the 2002-2003 cohort (P < .001), after adjustment for significant confounders including sex, income level, education level, and comorbidity burden. Sulfonylureas were the most commonly used agents, though their use declined over time; thiazolidinedione use decreased; and incretin use increased (all P < .001). CONCLUSIONS There was a significant increase in diabetes treatment intensification between 2002 and 2010. Choice of secondline agents changed as well, with decreasing prevalence of thiazolidinedione and sulfonylurea use and rising prevalence of incretin use.

Abstract
PURPOSE The workload of health care and its impact on patient functioning and well-being is known as treatment burden. The purpose of this study was to finalize a conceptual framework of treatment burden that will be used to inform a new patient-reported measure of this construct. PATIENTS AND METHODS Semi-structured interviews were conducted with 50 chronically ill patients from a large academic medical center (n=32) and an urban safety-net hospital (n=18). We coded themes identifying treatment burden, with the themes harmonized through discussion between multiple coders. Four focus groups, each with five to eight participants with chronic illness, were subsequently held to confirm the thematic structure that emerged from the interviews. RESULTS Most interviewed patients (98%) were coping with multiple chronic conditions. A preliminary conceptual framework using data from the first 32 interviews was evaluated and was modified using narrative data from 18 additional interviews with a racially and socioeconomically diverse sample of patients. The final framework features three overarching themes with associated subthemes. These themes included: 1) work patients must do to care for their health (eg, taking medications, keeping medical appointments, monitoring health); 2) challenges/stressors that exacerbate perceived burden (eg, financial, interpersonal, provider obstacles); and 3) impacts of burden (eg, role limitations, mental exhaustion). All themes and subthemes were subsequently confirmed in focus groups. CONCLUSION The final conceptual framework can be used as a foundation for building a patient self-report measure to systematically study treatment burden for research and analytical purposes, as well as to promote meaningful clinic-based dialogue between patients and providers about the challenges inherent in maintaining complex self-management of health.

Abstract
PURPOSE To explore perceptions and experiences of Peruvian medical students about observed, preferred, and feasible decision-making approaches. METHODS We surveyed senior medical students from 19 teaching hospitals in 4 major cities in Peru. The self-administered questionnaire collected demographic information, current approach, exposure to role models for and training in shared decision making, and perceptions of the pertinence and feasibility of the different decision-making approaches in general as well as in challenging scenarios. RESULTS A total of 327 senior medical students (51% female) were included. The mean age was 25 years. Among all respondents, 2% reported receiving both theoretical and practical training in shared decision making. While 46% of students identified their current decision-making approach as clinician-as-perfect-agent, 50% of students identified their teachers with the paternalistic approach. Remarkably, 53% of students thought shared decision making should be the preferred approach and 50% considered it feasible in Peru. Among the 10 challenging scenarios, shared decision making reached a plurality (40%) in only one scenario (terminally ill patients). CONCLUSION Despite limited exposure and training, Peruvian medical students aspire to practice shared decision making but their current attitude reflects the less participatory approaches they see role modeled by their teachers.

Abstract
BACKGROUND The presence of germline mutations in sporadic pheochromocytomas and paragangliomas (SPPs) may change the clinical management of both index patients and their family members. However, the frequency of germline mutations in SPPs is unknown. OBJECTIVE To describe the frequency of germline mutations in SPPs and to determine the value of testing index patients and their family members for these mutations. METHODS We searched databases through June 2012 for observational studies of patients with SPPs who underwent germline genetic testing. The criteria used to define sporadic tumours were (i) the absence of a family history of PCC/PG, (ii) the absence of syndromic features, (iii) the absence of bilateral disease and (iv) the absence of metastatic disease. RESULTS We included 31 studies including 5031 patients (mean age 44). These patients received tests for any of these ten mutations: SDHAF2, RET, SDHD, SDHB, SDHC, VHL, TMEM127, MAX, Isocitrate Dehydrogenase Mutation (IDH) and NF1. The overall frequency of germline mutation in SPP was 551 of 5031 or 11%; when studies with patients fulfilling four criteria for sporadic tumours were used, the frequency was 171 of 1332 or 13%. The most common germline mutation was SDHB 167 of 3611 (4·6%). Little outcome data were available to assess the benefits of genetic testing in index cases and family members. CONCLUSIONS The frequency of germline mutations in SPPs is approximately 11-13% and the most common mutations affect less than 1 in 20 patients. The value of testing for germline mutations in patients with SPPs and their family members is unknown, as the balance of potential benefits and harms remains unclear.

Abstract
CONTEXT Various drugs affect body weight as a side effect. OBJECTIVE We conducted this systematic review and meta-analysis to summarize the evidence about commonly prescribed drugs and their association with weight change. DATA SOURCES MEDLINE, DARE, and the Cochrane Database of Systematic Reviews were searched to identify published systematic reviews as a source for trials. STUDY SELECTION We included randomized trials that compared an a priori selected list of drugs to placebo and measured weight change. DATA EXTRACTION We extracted data in duplicate and assessed the methodological quality using the Cochrane risk of bias tool. RESULTS We included 257 randomized trials (54 different drugs; 84 696 patients enrolled). Weight gain was associated with the use of amitriptyline (1.8 kg), mirtazapine (1.5 kg), olanzapine (2.4 kg), quetiapine (1.1 kg), risperidone (0.8 kg), gabapentin (2.2 kg), tolbutamide (2.8 kg), pioglitazone (2.6 kg), glimepiride (2.1 kg), gliclazide (1.8 kg), glyburide (2.6 kg), glipizide (2.2 kg), sitagliptin (0.55 kg), and nateglinide (0.3 kg). Weight loss was associated with the use of metformin (1.1 kg), acarbose (0.4 kg), miglitol (0.7 kg), pramlintide (2.3 kg), liraglutide (1.7 kg), exenatide (1.2 kg), zonisamide (7.7 kg), topiramate (3.8 kg), bupropion (1.3 kg), and fluoxetine (1.3 kg). For many other remaining drugs (including antihypertensives and antihistamines), the weight change was either statistically nonsignificant or supported by very low-quality evidence. CONCLUSIONS Several drugs are associated with weight change of varying magnitude. Data are provided to guide the choice of drug when several options exist and institute preemptive weight loss strategies when obesogenic drugs are prescribed.

Abstract
BACKGROUND Shared decision making is promoted to improve cancer care quality. Patients and clinicians may have different ideas about what constitutes a cancer care decision, which may limit the validity of self-reported measures of shared decision making. We sought to estimate the extent to which patients and clinicians agree on whether a cancer care decision was made during an outpatient encounter. METHODS We surveyed patients and clinicians immediately after an oncology encounter at a large, tertiary medical centre and calculated agreement in response to the single-item question, 'Was a specific decision about cancer care made during the appointment today?' Answer options were 'yes' and 'no'. Participants were 315 oncology patients, with any solid tumour malignancy and at any stage of management, and their clinicians (22 staff oncologists, nine senior fellows and five nurse practitioners). RESULTS Patients and clinicians reported having made a cancer care decision in 184 (58%) and 174 (55%) of encounters, respectively. They agreed on whether a cancer care decision was made in 213 (68%) of encounters (chance-adjusted agreement was 0.34); in 56 of the 102 discordant encounters, the patient reported making a decision while the clinician did not. We found no significant correlates with discordance. CONCLUSIONS Patients and clinicians do not always agree on whether a cancer care decision was made. As such, measures that ask patients and/or clinicians to evaluate a decision-making process or outcome may be methodologically insufficient when they do not explicitly orient respondents towards the thing they are being asked to assess.

Abstract
BACKGROUND Providing patient-centered care requires that patients partner in their personal health-care decisions to the full extent desired. Patient decision aids facilitate processes of shared decision-making between patients and their clinicians by presenting relevant scientific information in balanced, understandable ways, helping clarify patients' goals, and guiding decision-making processes. Although international standards stipulate that patients and clinicians should be involved in decision aid development, little is known about how such involvement currently occurs, let alone best practices. This systematic review consisting of three interlinked subreviews seeks to describe current practices of user involvement in the development of patient decision aids, compare these to practices of user-centered design, and identify promising strategies. METHODS/DESIGN A research team that includes patient and clinician representatives, decision aid developers, and systematic review method experts will guide this review according to the Cochrane Handbook and PRISMA reporting guidelines. A medical librarian will hand search key references and use a peer-reviewed search strategy to search MEDLINE, EMBASE, PubMed, Web of Science, the Cochrane Library, the ACM library, IEEE Xplore, and Google Scholar. We will identify articles across all languages and years describing the development or evaluation of a patient decision aid, or the application of user-centered design or human-centered design to tools intended for patient use. Two independent reviewers will assess article eligibility and extract data into a matrix using a structured pilot-tested form based on a conceptual framework of user-centered design. We will synthesize evidence to describe how research teams have included users in their development process and compare these practices to user-centered design methods. If data permit, we will develop a measure of the user-centeredness of development processes and identify practices that are likely to be optimal. DISCUSSION This systematic review will provide evidence of current practices to inform approaches for involving patients and other stakeholders in the development of patient decision aids. We anticipate that the results will help move towards the establishment of best practices for the development of patient-centered tools and, in turn, help improve the experiences of people who face difficult health decisions.

Accuracy of magnetic resonance imaging in diagnosis of liver iron overload: a systematic review and meta-analysis. Clin Gastroenterol Hepatol 2015; 13:55-63.e5.

Abstract
BACKGROUND & AIMS Guidelines advocate use of magnetic resonance imaging (MRI) to estimate concentrations of iron in liver, to identify patients with iron overload, and to guide titration of chelation therapy. However, this recommendation was not based on a systematic synthesis and analysis of the evidence for MRI's diagnostic accuracy. METHODS We conducted a systematic review and meta-analysis to investigate the diagnostic accuracy of MRI in identifying liver iron overload in patients with hereditary hemochromatosis, hemoglobinopathy, or myelodysplastic syndrome; liver biopsy analysis was used as the reference standard. We searched MEDLINE and EMBASE databases, the Cochrane Library, and gray literature, and computed summary receiver operating curves by fitting hierarchical models. We assessed methodologic quality using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. RESULTS Our final analysis included 20 studies (819 patients, total). Sensitivity and specificity values varied greatly, ranging from 0.00 to 1.00 and from 0.50 to 1.00, respectively. Because of substantial heterogeneity and variable positivity thresholds, we calculated only summary receiver operating curves (and summary estimate points for studies that used the same MRI sequences). T2 spin echo and T2* gradient-recalled echo MRI sequences accurately identified patients without liver iron overload (liver iron concentration > 7 mg Fe/g dry liver weight) (negative likelihood ratios, 0.10 and 0.05 respectively). However, these MRI sequences are less accurate in establishing a definite diagnosis of liver iron overload (positive likelihood ratio, 8.85 and 4.86, respectively). CONCLUSIONS Based on a meta-analysis, measurements of liver iron concentration by MRI may be accurate enough to rule out iron overload, but not to definitely identify patients with this condition. Most studies did not use explicit and prespecified MRI thresholds for iron overload, therefore some patients may have been diagnosed inaccurately with this condition. More studies are needed of standardized MRI protocols and to determine the effects of MRI surveillance on the development of chronic liver disease and patient survival.

Abstract
BACKGROUND Severe insufficiencies in the supply and inequities in the distribution of health care professionals, facilities, and services create conditions for limited quality of care and lack of trust - even violent conflict - between clinicians and patients in the People's Republic of China. Alongside structural reform, shared decision-making (SDM) may help meet the needs and advance the goals of each patient. Little is known, however, about the realities and opportunities for SDM in the People's Republic of China. METHODS To identify reports of SDM in the People's Republic of China, we used multiple sources, including: several databases, searched in English and Chinese, online journals, and clinical trial registries. In addition, we contacted experts in the field to identify any articles missed through our other search strategies. We included all trials and surveys reporting on SDM in Chinese patients. We summarized these studies by describing them with particular attention to reports of patient decisional preference and of the impact of SDM interventions on outcomes in Chinese patients. RESULTS We identified five surveys examining patient preference for SDM and nine studies examining constructs related to SDM in Chinese patients, but none involving patients in Mainland China. We could not find any reports of development, testing, or implementation of SDM tools for patients in Mainland China. CONCLUSION The research on SDM in the People's Republic of China is limited, with almost no direct evidence to inform clinical policies or implementation. Although multiple barriers are apparent, the value of implementing, testing, and disseminating effective SDM in the People's Republic of China in terms of patient experience and outcomes demands urgent realization.

The design of a low literacy decision aid about rheumatoid arthritis medications developed in three languages for use during the clinical encounter. BMC Med Inform Decis Mak 2014; 14:104. [PMID: 25649726 PMCID: PMC4363399 DOI: 10.1186/s12911-014-0104-8] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2014] [Accepted: 11/03/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Shared decision-making in rheumatoid arthritis (RA) care is a priority among policy makers, clinicians and patients both nationally and internationally. Demands on patients to have basic knowledge of RA, treatment options, and details of risk and benefit when making medication decisions with clinicians can be overwhelming, especially for those with limited literacy or limited English language proficiency. The objective of this study is to describe the development of a medication choice decision aid for patients with rheumatoid arthritis (RA) in three languages using low literacy principles. METHODS Based on the development of a diabetes decision aid, the RA decision aid (RA Choice) was developed through a collaborative process involving patients, clinicians, designers, decision-aid and health literacy experts. A combination of evidence synthesis and direct observation of clinician-patient interactions generated content and guided an iterative process of prototype development. RESULTS Three iterations of RA Choice were developed and field-tested before completion. The final tool organized data using icons and plain language for 12 RA medications across 5 issues: frequency of administration, time to onset, cost, side effects, and special considerations. The tool successfully created a conversation between clinician and patient, and garnered high acceptability from clinicians. CONCLUSIONS The process of collaboratively developing an RA decision aid designed to promote shared decision making resulted in a graphically-enhanced, low literacy tool. The use of RA Choice in the clinical encounter has the potential to enhance communication for RA patients, including those with limited health literacy and limited English language proficiency.

Abstract
INTRODUCTION Chronic neuropathic pain is associated with reduced health-related quality of life and substantial socioeconomic costs. Current research addressing management of chronic neuropathic pain is limited. No review has evaluated all interventional studies for chronic neuropathic pain, which limits attempts to make inferences regarding the relative effectiveness of treatments. METHODS AND ANALYSIS We will conduct a systematic review of all randomised controlled trials evaluating therapies for chronic neuropathic pain. We will identify eligible trials, in any language, by a systematic search of CINAHL, EMBASE, MEDLINE, AMED, HealthSTAR, DARE, PsychINFO and the Cochrane Central Registry of Controlled Trials. Eligible trials will be: (1) enrol patients presenting with chronic neuropathic pain, and (2) randomise patients to alternative interventions (pharmacological or non-pharmacological) or an intervention and a control arm. Pairs of reviewers will, independently and in duplicate, screen titles and abstracts of identified citations, review the full texts of potentially eligible trials and extract information from eligible trials. We will use a modified Cochrane instrument to evaluate risk of bias of eligible studies, recommendations from the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) to inform the outcomes we will collect, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to evaluate our confidence in treatment effects. When possible, we will conduct: (1) in direct comparisons, a random-effects meta-analysis to establish the effect of reported therapies on patient-important outcomes; and (2) a multiple treatment comparison meta-analysis within a Bayesian framework to assess the relative effects of treatments. We will define a priori hypotheses to explain heterogeneity between studies, and conduct meta-regression and subgroup analyses consistent with the current best practices. ETHICS AND DISSEMINATION We do not require ethics approval for our proposed review. We will disseminate our findings through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER PROSPERO (CRD42014009212).
