ABSTRACT
For over 50 years, clinical research methodology has wrestled with the problem of the lack of correspondence between tests of treatments and applications of treatments. The former comprise of trials featuring scrupulous control of patient eligibility, treatment compliance, clinician expertise, follow-up intensity, and so on. In applying a validated treatment, the practitioner has to confront considerable real-world variation in potential patients and in implementation regimes. The remedy, going by the name of "pragmatic trials," is to conduct clinical trials in conditions corresponding more closely to everyday practice. This solution has proved easier to utter than to execute, and the paper reviews the extensive literature on pragmatic trials, seeking to assess whether it has terminated in clarity or contestation.

BACKGROUND: Optimizing the organization of care for community-dwelling frail older people is an important issue in many Western countries. In Belgium, a series of complex, innovative, bottom-up interventions was recently designed and implemented to help frail older people live at home longer. As the effectiveness of these interventions may vary between different population groups according to their long-term care needs, they must be evaluated by comparison with a control group that has similar needs. METHODS: The goal was to identify target groups for these interventions and to establish control groups with similar needs and to explore, per group, the extent to which the utilization of long-term care is matched to needs. We merged two databases: a clinical prospective database and the routine administrative database for healthcare reimbursements. Through Principal Component Analysis followed by Clustering, the intervention group was first stratified into disability profiles. Per profile, comparable control groups for clinical variables were established, based on propensity scores. Using chi-squared tests and logistic regression analysis, long-term care utilization at baseline was then compared per profile and group studied. RESULTS: Stratification highlighted five disability profiles: people with low-level limitations; people with limitations in instrumental activities of daily life and low-level of cognitive impairment; people with functional limitations; people with functional and cognitive impairments; and people with functional, cognitive, and behavioral problems. These profiles made it possible to identify long-term care needs. For instance, at baseline, those who needed more assistance with hygiene tasks also received more personal nursing care (P < 0.05). However, there were some important discrepancies between the need for long-term care and its utilization: while 21% of patients who were totally dependent for hygiene tasks received no personal nursing care, personal nursing care was received by 33% of patients who could perform hygiene tasks. CONCLUSIONS: The disability profiles provide information on long-term care needs but not on the extent to which those needs are met. To assess the effectiveness of interventions, controls at baseline should have similar disability profiles and comparable long-term care utilization. To allow for large comparative effectiveness studies, these dimensions should ideally be available in routine databases.

Meta-analysis is a firmly established methodology and an integral part of the process of generating knowledge across the empirical sciences. Meta-analysis has also focused on methodology and has become a dominant critic of methodological shortcomings. We highlight several problematic issues on how we research in psychology: excess of heterogeneity in the results and difficulties for replication, publication bias, suboptimal methodological quality, and questionable practices of the researchers. These and other problems led to a "crisis of confidence" in psychology. We discuss how the meta-analytical perspective and its procedures can help to overcome the crisis. A more cooperative perspective, instead of a competitive one, can shift to consider replication as a more valuable contribution. Knowledge cannot be based in isolated studies. Given the nature of the object of study of psychology the natural unit to generate knowledge must be the estimated distribution of the effect sizes, not the dichotomous decision on statistical significance in specific studies. Some suggestions are offered on how to redirect researchers' research and practices, so that their personal interests and those of science as such are better aligned
El meta-análisis es una metodología firmemente establecida y una parte integral del proceso de generación de conocimiento en las ciencias empíricas. El meta-análisis también se ha centrado en la metodología y se ha convertido en uno de los principales críticos de las deficiencias metodológicas. Destacamos varios puntos problemáticos sobre cómo investigamos en psicología: exceso de heterogeneidad en los resultados y dificultades para la replicación, sesgo de publicación, calidad metodológica sub-óptima y prácticas cuestionables de los investigadores. Estos y otros problemas condujeron a una "crisis de confianza" en psicología. Discutimos cómo la perspectiva meta-analítica y sus procedimientos pueden ayudar a superar la crisis. Una perspectiva más cooperativa, en lugar de competitiva, puede ayudar a cambiar para que consideremos la replicación como una contribución más valiosa. El conocimiento no puede basarse en estudios aislados. Dada la naturaleza del objeto de estudio de la psicología la unidad natural para generar conocimiento debe ser la distribución estimada del tamaño del efecto, no la decisión dicotómica sobre la significación estadística en estudios específicos. Se ofrecen algunas sugerencias sobre cómo redirigir la investigación y las prácticas de los investigadores, de modo que sus intereses personales y los de la ciencia en sí estén más alineados

BACKGROUND: The Core Outcome Measures in Effectiveness Trials (COMET) database is a publically available, searchable repository of published and ongoing core outcome set (COS) studies. An annual systematic review update is carried out to maintain the currency of database content. METHODS: The methods used in the fourth update of the systematic review followed the same approach used in the original review and previous updates. Studies were eligible for inclusion if they reported the development of a COS, regardless of any restrictions by age, health condition or setting. Searches were carried out in March 2018 to identify studies that had been published or indexed between January 2017 and the end of December 2017. RESULTS: Forty-eight new studies, describing the development of 56 COS, were included. There has been an increase in the number of studies clearly specifying the scope of the COS in terms of the population (n = 43, 90%) and intervention (n = 48, 100%) characteristics. Public participation has continued to rise with over half (n = 27, 56%) of studies in the current review including input from members of the public. The rate of inclusion of all stakeholder groups has increased, in particular participation from non-clinical research experts has risen from 32% (mean average in previous reviews) to 62% (n = 29). Input from participants located in Australasia (n = 17; 41%), Asia (n = 18; 44%), South America (n = 13; 32%) and Africa (n = 7; 17%) have all increased since the previous reviews. CONCLUSION: This update included a pronounced increase in the number of new COS identified compared to the previous three updates. There was an improvement in the reporting of the scope, stakeholder participants and methods used. Furthermore, there has been an increase in participation from Australasia, Asia, South America and Africa. These advancements are reflective of the efforts made in recent years to raise awareness about the need for COS development and uptake, as well as developments in COS methodology.

BACKGROUND: Core outcome sets (COS) comprise a minimum set of outcomes that should be measured and reported in all trials for a specific health condition. The COMET (Core Outcome Measures in Effectiveness Trials) Initiative maintains an up to date, publicly accessible online database of published and ongoing COS. An annual systematic review update is an important part of this process. METHODS: This review employed the same, multifaceted approach that was used in the original review and the previous two updates. This approach has identified studies that sought to determine which outcomes/domains to measure in clinical trials of a specific condition. This update includes an analysis of the inclusion of participants from low and middle income countries (LMICs) as identified by the OECD, in these COS. RESULTS: Eighteen publications, relating to 15 new studies describing the development of 15 COS, were eligible for inclusion in the review. Results show an increase in the use of mixed methods, including Delphi surveys. Clinical experts remain the most common stakeholder group involved. Overall, only 16% of the 259 COS studies published up to the end of 2016 have included participants from LMICs. CONCLUSION: This review highlights opportunities for greater public participation in COS development and the involvement of stakeholders from a wider range of geographical settings, in particular LMICs.

The term comparative effectiveness research (CER) took center stage with passage of the American Recovery and Reinvestment Act (2009). The companion US$1.1 billion in funding prompted the launch of initiatives to train the scientific workforce capable of conducting and using CER. Passage of the Patient Protection and Affordable Care Act (2010) focused these initiatives on patients, coining the term 'patient-centered outcomes research' (PCOR). Educational and training initiatives were soon launched. This report describes the initiative of the Pharmaceutical Research and Manufacturers Association of America (PhRMA) Foundation. Through provision of grant funding to six academic Centers of Excellence, to spearheading and sponsoring three national conferences, the PhRMA Foundation has made significant contributions to creation of the scientific workforce that conducts and uses CER/PCOR.

Registry-based randomized controlled trials are defined as pragmatic trials that use registries as a platform for case records, data collection, randomization, and follow-up. Recently, the application of registry-based randomized controlled trials has attracted increasing attention in health research to address comparative effectiveness research questions in real-world settings, mainly due to their low cost, enhanced generalizability of findings, rapid consecutive enrollment, and the potential completeness of follow-up for the reference population, when compared with conventional randomized effectiveness trials. However several challenges of registry-based randomized controlled trials have to be taken into consideration, including registry data quality, ethical issues, and methodological challenges. In this article, we summarize the advantages, challenges, and areas for future research related to registry-based randomized controlled trials.

BACKGROUND: In recent years, comparative effectiveness tools and methods have evolved to assist health care decision makers in identifying optimal therapies. In-person training programs on comparative effectiveness research may be helpful in understanding and applying this information. OBJECTIVE: To provide a follow-up assessment of the use of comparative effectiveness research (CER) in the pharmacy and therapeutics (P&T) committee decision-making process, using information collected from participants 1 year after attending a live continuing education program, in which participants were taught about CER designs and how to access available CER resources through the Agency for Healthcare Research and Quality (AHRQ) Effective Health Care (EHC) Program. METHODS: A retrospective, cross-sectional questionnaire was developed and mailed to 2 groups of individuals: CER workshop attendees and interested nonattendees (expressing an interest in attending a workshop but did not attend for unknown reasons). The questionnaire asked respondents to indicate personal and organizational use of CER in the decision-making process. Participants were asked to indicate whether their knowledge, ability, and use of CER studies increased since participating in the program. Data were analyzed using nonparametric tests to compare the responses of attendees and nonattendees, as well as overall reliability of the instrument. RESULTS: A total of 164 respondents completed the questionnaire (63 attendees and 101 nonattendees; overall response rate = 44%). The majority of respondents were pharmacists (n = 157, 95.7%) and were affiliated with a hospital (n = 106, 64.6%). Proportions of attendees and nonattendees differed significantly in the use of EHC research reviews/reports (45% and 28%, respectively; P = 0.02) and EHC executive summaries of research reviews/reports (48% and 29%, respectively; P = 0.01). At 1-year follow-up, the majority of attendees reported an increase ("somewhat" or "very much") in knowledge of CER (91.5%), ability to use CER (83.0%), and use of CER studies (58.7%). CONCLUSIONS: Health professionals attending a continuing education CER program reported higher use of EHC CER materials compared with nonattendees. Additionally, attendees reported increased use of CER in clinical decision making. A continuing education program such as this may provide an effective avenue for introducing CER methods and resources to the P&T committee and clinical decision-making processes.

BACKGROUND: Understanding how treatments work in the real world and in real patients is an important and complex task. In recent years, comparative effectiveness research (CER) studies have become more available for health care providers to inform evidence-based decision making. There is variability in the strengths and limitations of this new evidence, and researchers and decision makers are faced with challenges when assessing the quality of these new methods and CER studies. OBJECTIVES: To (a) describe an online tool developed by the CER Collaborative, composed of the Academy of Managed Care Pharmacy, the International Society for Pharmacoeconomics and Outcomes Research, and the National Pharmaceutical Council, and (b) provide an early evaluation of the training program impact on learners' self-reported abilities to evaluate and incorporate CER studies into their decision making. METHODS: To encourage greater transparency, consistency, and uniformity in the development and assessment of CER studies, the CER Collaborative developed an online tool to assist researchers, new and experienced clinicians, and decision makers in producing and evaluating CER studies. A training program that supports the use of the online tool was developed to improve the ability and confidence of individuals to apply CER study findings in their daily work. Seventy-one health care professionals enrolled in 3 separate cohorts for the training program. Upon completion, learners assessed their abilities to interpret and apply findings from CER studies by completing on online evaluation questionnaire. RESULTS: The first 3 cohorts of learners to complete the training program consisted of 71 current and future health care practitioners and researchers. At completion, learners indicated high confidence in their CER evidence assessment abilities (mean = 4.2). Learners reported a 27.43%-59.86% improvement in capabilities to evaluate various CER studies and identify study design flaws (mean evaluation before CER Certificate Program [CCP] scores = 1.86-3.14 and post-CCP scores = 3.92-4.24). Additionally, 63% of learners indicated that they expected to increase their use of evidence from CER studies in at least 1-2 problem decisions per month. CONCLUSIONS: The CER Collaborative has responded to the need for increased practitioner training to improve understanding and application of new CER studies. The CER Collaborative tool and certificate training program are innovative solutions to help decision makers meet the challenges they face in honing their skills to best incorporate credible and relevant CER evidence into their decision making. DISCLOSURES: The CER Collaborative, the development of the questionnaires and web-based tool, and the development of the CER Certificate Program were supported by grants and in-kind contributions from the Academy of Managed Care Pharmacy (AMCP), the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), and the National Pharmaceutical Council (NPC).

OBJETIVO: Evaluar la eficiencia de la terapia combinada de metformina y dapagliflozina, un nuevo antidiabético oral con un mecanismo de acción independiente de la insulina, en el tratamiento de la diabetes mellitus tipo 2 (DM2) en comparación con inhibidores de DPP4, sulfonilureas y tiazolidindionas, combinados también con metformina. DISEÑO: Análisis de coste-efectividad utilizando un modelo de simulación de eventos discretos a partir de los resultados de los ensayos clínicos disponibles y considerando un horizonte temporal de toda la vida del paciente. Emplazamiento: Perspectiva del Sistema Nacional de Salud. PARTICIPANTES: El modelo simuló la historia natural de 30.000 pacientes con DM2 para cada opción comparada. MEDICIONES PRINCIPALES: Años de vida ajustados por calidad (AVAC) y consecuencias económicas del manejo de la enfermedad y sus complicaciones. Se consideraron los costes directos (actualizados a euros de 2013) y se aplicó un descuento del 3% tanto para costes como para resultados en salud. RESULTADOS: El análisis principal comparó dapagliflozina con los inhibidores de DPP4, resultando dapagliflozina como una opción de tratamiento que aportaría una ligera mayor efectividad (0,019 AVAC) con menores costes totales asociados (−42 Euros). En los análisis adicionales, dapagliflozina fue una opción coste-efectiva en comparación con sulfonilureas y tiazolidindionas con razones de coste por AVAC ganado de 3.560 Euros y 2.007 Euros, respectivamente. Los análisis de sensibilidad univariantes y probabilístico confirmaron la solidez de los RESULTADOS: CONCLUSIONES: Los resultados del análisis realizado sugieren que dapagliflozina, en combinación con metformina, sería una alternativa coste-efectiva en el contexto español para el tratamiento de la DM2
OBJECTIVE: To assess the efficiency of the combined therapy with metformin and dapagliflozin, a new oral anti-diabetic drug with an insulin-independent mechanism of action, in the treatment of type-2 diabetes mellitus (T2DM) compared to DPP4 inhibitors, sulphonylureas and thiazolidindiones, also combined with metformin. DESIGN: Cost-effectiveness analysis using a discrete event simulation model based on the results of the available clinical trials and considering patient's entire life as time horizon. SETTING: National Health System perspective. PARTICIPANTS: The model simulated the natural history of 30,000 patients with T2DM for each of the options compared. MAIN MEASUREMENTS: Quality-adjusted life-years (QALY) and economic consequences of managing the disease and its complications. The analysis considered direct costs updated to 2013. A discount rate of 3% was applied to costs and health outcomes. RESULTS: In the main analysis comparing dapagliflozin with DPP4 inhibitors, dapagliflozin resulted in a treatment option that would provide a slightly higher effectiveness (0.019 QALY) and lower overall associated costs (- 42 Euros). In the additional analyses, dapagliflozin was a cost-effective option compared with sulphonylureas and thiazolidinediones resulting in a cost per QALY gained of 3,560 Euros and 2,007 Euros, respectively. The univariate and probabilistic sensitivity analyses confirmed the robustness of the RESULTS: CONCLUSIONS: The results of the analyses performed suggested that dapagliflozin, in combination with metformin, would be a cost-effective alternative in the Spanish context for the treatment of T2DM

The Patient-Centered Outcomes Research Institute has accelerated conversations about the importance of actively engaging stakeholders in all aspects of comparative effectiveness research (CER). Other scientific disciplines have a history of stakeholder engagement, yet few empirical examples exist of how these stakeholders can inform and enrich CER. Here we present a case study which includes the methods used to engage stakeholders, what we learned from them, and how we incorporated their ideas in a CER project. We selected stakeholders from key groups, built relationships with them and collected their feedback through interviews, observation and ongoing meetings during the four research process phases: proposal development, adapting study methods, understanding the context and information technology tool design and refinement.

AIM: Explore key factors influencing future expectations for the production of evidence from comparative effectiveness research for drugs in the USA in 2020 and construct three plausible future scenarios. MATERIALS & METHODS: Semistructured key informant interviews and three rounds of modified Delphi with systematic scenario-building methods. RESULTS & CONCLUSION: Most influential key factors were: health delivery system integration; electronic health record development; exploitation of very large databases and mixed data sources; and proactive patient engagement in research. The scenario deemed most likely entailed uneven development of large integrated health systems with pockets of increased provider risk for patient care, enhanced data collection systems, changing incentives to do comparative effectiveness research and new opportunities for evidence generation partnerships.

Health research, including health outcomes and comparative effectiveness research, is on the cusp of a golden era of access to digitized real-world data, catalyzed by the adoption of electronic health records and the integration of clinical and biological information with other data. This era promises more robust insights into what works in health care. Several barriers, however, will need to be addressed if the full potential of these new data are fully realized; these will involve both policy solutions and stakeholder cooperation. Although a number of these issues have been widely discussed, we focus on the one we believe is the most important-the facilitation of greater openness among public and private stakeholders to collaboration, connecting information and data sharing, with the goal of making robust and complete data accessible to all researchers. In this way, we can better understand the consequences of health care delivery, improve the effectiveness and efficiency of health care systems, and develop advancements in health technologies. Early real-world data initiatives illustrate both potential and the need for future progress, as well as the essential role of collaboration and data sharing. Health policies critical to progress will include those that promote open source data standards, expand access to the data, increase data capture and connectivity, and facilitate communication of findings.

Purpose. To assess the efficiency of pazopanib compared with trabectedin in the treatment of adult patients with selective subtypes of advanced soft-tissue sarcoma (STS) after chemotherapy failure. Methods. The progression of STS was modeled using a partitioned survival analysis model. Survival curves for pazopanib and trabectedin were modeled using data from PALETTE phase III clinical trial and based on unadjusted indirect comparison. Effectiveness was measured in quality-adjusted life years (QALY). The Spanish National Health System perspective was considered over a 10-year time horizon, including direct health care costs (Euros, 2014). A discount rate of 3 % was applied to both costs and outcomes. The robustness of the results was evaluated using univariate and probabilistic sensitivity analyses (PSA). Results. Pazopanib was associated with better health outcomes than trabectedin (0.705 versus 0.686 QALY). Pazopanib also showed lower direct health care costs (21,861 versus 45,338), mainly due to lower cost of pharmacological treatment (13,762 versus 33,392), administration (57 versus 2,955) and AE management (658 versus 1,695) costs. PSA confirmed that pazopanib was a dominant option in 71 % of the simulations performed. Conclusions. In this analysis, and from a health economics perspective, pazopanib was the option of choice versus trabectedin in the treatment of adult patients with advanced soft-tissue sarcoma after chemotherapy failure (AU)

Comparative effectiveness research (CER) is an important branch of pharmacoeconomics that systematically studies and evaluates the cost-effectiveness of medical interventions. CER plays instrumental roles in guiding government public health policy programs and insurance. Countries throughout the world use different methods of CER to help make medical decisions based on providing optimal therapy at a reduced cost. Expenses to the healthcare system continue to rise, and CER is one-way in which expenses could be curbed in the future by applying cost-effectiveness evidence to clinical decisions. China, India, South Korea, and the United Kingdom are of essential focus because these country's economies and health care expenses continue to expand. The structures and use of CER are diverse throughout these countries, and each is of prime importance. By conducting this thorough comparison of CER in different nations, strategies and organizational setups from different countries can be applied to help guide public health and medical decision-making in order to continue to expand the establishment and role of CER programs. The patient-centered medical home has been created to help reduce costs in the primary care sector and to help improve the effectiveness of therapy. Barriers to CER are also important as many stakeholders need to be able to work together to provide the best CER evidence. The advancement of CER in multiple countries throughout the world provides a possible way of reducing costs to the healthcare system in an age of expanding expenses.
