Drug treatment service procurement: A systematic review of models, goals, and outcomes.

Aim: To explore the goals and outcomes of public procurement of drug treatment services in OECD countries. The study explores how these complex services are procured and delivered. Methods and data: A systematic review of the literature (1990-2020) identified four partly overlapping models of drug treatment service procurement that are here labelled traditional, value-based, outcome-based, and innovative. Results: Even though different forms of drug treatment services procurement are common, only 12 empirical studies that focused on procurement were found. The four models differ in their approaches to design and performance specifications and the role of competition and collaboration in the co-creation of value. Conclusions: Competition and incentives improve neither the efficiency nor the quality or the outcomes of complex drug treatment services. Whereas many studies focus on payment mechanisms, there are important research gaps that relate to the co-creation of value with and for the service-users and other stakeholders.

Models and methods for hybrid system identification: a systematic survey*

Dynamical systems and processes that either exhibit non-smooth behaviours (e.g. through logic control or natural phenomena) or work in different modes of operation are usually represented using hybrid systems models, i.e. mathematical models that combine continuous dynamics with discrete-event dynamics. Identification of a hybrid system includes finding switching patterns and identification of model parameters to obtain a data-driven model. This survey paper provides a systematic review of models (how to parameterize the system) and methods (how to identify unknown parameters) proposed for hybrid system identification with an exposition of recent advances and developments, and further research directions.

A Systematic Review of Models Used in Cost-Effectiveness of Treatments in Spondyloarthritis

This review was aimed to evaluate health economic models used in evaluations of different treatment strategies in spondyloarthritis (SpA). Model-based health economic evaluation studies are increasing and complex models with short-term and long-term horizon are applied to investigate the cost-effectiveness of SpA treatments. The objective of this study was to carry out a systematic review of the evolution of health economic models used in the treatment of SpA. Electronic searches within MEDLINE and EMBASE were carried out using a predefined search strategy. Inclusion and exclusion criteria were used to select relevant studies. Data on country, intervention, evaluation perspective, type of model, time horizon, types of costs and effectiveness measurement were extracted. Eighteen models were described in 22 publications, of which 81.8% were European. Study perspectives included the societal (n=6), healthcare system and payer (n=14), or patient and government (n=1). Time horizon ranged from 52 weeks to lifetime. Markov model was the most frequently used model, only one individual patient simulation models accounting for uncertainty in multiple parameters was reported. Most studies compared different biologics (including different TNFi/biosimilar and IL-17A antibody) with conventional care (NSAIDs) because of the high prize. Only half of studies took indirect costs into account. Modeling is of importance in health economic evaluations of SpA treatment. Long-term costs especially indirect costs should be considered when comparing different treatment alternatives in order to provide more information for policy makers and clinicians.

Early warning system models and components in emergency and disaster: a systematic literature review protocol

BackgroundEmergency and disaster are on the rise in the world. One of the most important components of disaster risk management is the early warning system. Studies have shown divergent models of warning systems with different structures. However, since no systematic review of early warning systems in disasters has been conducted so far, a systematic review of the models, components, and structures of these systems is essential. This protocol is a systematic review study, which aims to evaluate the existing warning systems and their structure.MethodologyThis study attempts to comprehensively search the previous studies with terms and expressions including disaster, emergency model, early warning system, and their synonyms at MESH. To this end, English articles, which have been published from 1980 to 2019, will be assessed. Google Scholar, PubMed, Web of Science, and Scopus databases as well as relevant specialized websites will be searched. Studies will be evaluated by two individuals independently.DiscussionTo the best of our knowledge, no systematic review of models, structures, and components of the early warning system has been conducted so far. This study is the first attempt to comprehensively evaluate the models and components of early warning systems. Accordingly, this study will provide evidence of models, structures and elements of the early warning systems.Systematic review registrationPROSPERO CRD42018116111

A Systematic Review of Models Used and Preferences for Continuing Education and Continuing Professional Development of Pharmacists.

Continuing Education (CE) or Continuing Professional Development (CPD) are used by pharmacists globally to maintain up-to-date knowledge and skills throughout their careers. The primary aim of this study was to identify the formats or models used by pharmacists for CE and CPD globally. The secondary aim was to identify preferences of pharmacists, in relation to the variety of formats or models used to fulfil mandatory requirements, in order to support future planning of lifelong learning events. A systematic review was performed using PubMed, Science Direct, and Web of Science covering a time period from 1995 until March 2018. Searches were conducted in English, with studies on undergraduate studies being excluded. Eighteen papers from an initial search of 4561 were included from 2004 to 2014. All studies focused on pharmacists. Three studies identified face-to-face learning as a preference, with six studies identifying a positive impact of interactive learning. All four identified studies focusing on online provision were linked to CE. One study highlighted the benefits of blended learning. Two studies identified concluded that no one size fits all. A clear structure of event was highlighted in three studies. Three studies highlighted the relevance of topics to practice, and two studies showed the need for opportunities to apply knowledge. Due to the variety of formats and no consistent model, no perfect model or activity has been identified. However, CPD showed increased practice outcomes versus CE. Although an increasing amount of technology is being utilized, face-to-face learning is still preferred. Interactive, multiple-format learning should be used where possible, to reflect preferences of different learners. There is a need for a structured approach to the planning and learning event itself to support CE and CPD.

A Decade of LMS Acceptance and Adoption Research in Sub-Sahara African Higher Education: A Systematic Review of Models, Methodologies, Milestones and Main Challenges

A decade has elapsed since the Learning Management System (LMS) technology permeated its way into higher education in Sub-Saharan Africa (SSA), offering new paradigms of both blended and online mode e-learning delivery. Parallel to other continents, the introduction of LMS stimulated acceptance and adoption intentions among stakeholders in higher education. This necessitated research into faculty members’ and students’ LMS acceptance and adoption intentions. While some research has been conducted in this dimension, the evidential facts are scattered. There is a need to agglomerate these studies to project a better picture of study patterns and results, to be abreast of the current state of the literature and better direct future research. This study sought to bridge the gap by way of a systematic review of previous studies within a decade of LMS acceptance research in SSA, placing them in contextual paradigms of models, methodologies, milestones, subjects, countries, findings and challenges. Results from a systematic review of 31 studies, revealed key determinants of LMS acceptance/adoption to be Attitude and Perceived Usefulness; followed by Performance Expectancy and Perceived Ease of Use; then lastly Social Influence. Major challenges to LMS implementation identified were ICT infrastructure; LMS usage skills and training; LMS system quality, LMS use policy and management support. TAM1 was the dominant model employed and students were the main subject of studies. Moreover, quantitative approach was the preferred design with Regression as the main statistical tool used for data analysis. The study recommended among others that more UTAUT or TAM3 based studies employing mixed method design with instructors as subjects, using structural equation modelling analysis are needed in SSA LMS research. Leadership and top management of higher education institutions should focus more on ICT infrastructure, LMS usage skills/training, LMS quality related issues, support and ICT policy formulation.

Systematic review of models used in economic analyses in moderate-to-severe asthma and COPD

Background:Respiratory diseases exert a substantial burden on society, with newer drugs increasingly adding to the burden. Economic models are often used, but seldom reviewed.Purpose:To summarize economic models used in economic analyses of drugs treating moderate-to-severe/very severe asthma or chronic obstructive pulmonary disease (COPD).Methods:This study searched Medline and Embase from inception to the end of February 2015 for cost-effectiveness/utility analyses that examined at least one drug against placebo, another drug, or other standard therapy in asthma or COPD. Two reviewers independently searched and extracted data with differences adjudicated via consensus discussion. Data extracted included model used and its qualities, validation methods, treatments compared, disease severity, analytic perspective, time horizon, data collection (pro- or retrospective), input rates and sources, costs and sources, planned sensitivity analyses, criteria for cost-effectiveness, reported outcomes, and sponsor.Results:This study analyzed 53 articles; 14 (25%) on asthma and 39 (75%) COPD. Markov models were commonly used for both asthma and COPD-related economic evaluations. Relatively few studies validated their model. For asthma-related studies, 10 examined inhaled corticosteroids and nine studied omalizumab. Placebo or standard therapy was the comparison in 11 studies and active drugs in the remainder.Conclusions:Few studies include validation of their models. Furthermore, controversy concerning some results was uncovered in this study, which needs to be avoided in the future.

A systematic review of models used in cost-effectiveness analyses of preventing osteoporotic fractures

This review was aimed at the evolution of health economic models used in evaluations of clinical approaches aimed at preventing osteoporotic fractures. Models have improved, with medical continuance becoming increasingly recognized as a contributor to health and economic outcomes, as well as advancements in epidemiological data. Model-based health economic evaluation studies are increasingly used to investigate the cost-effectiveness of osteoporotic fracture preventions and treatments. The objective of this study was to carry out a systematic review of the evolution of health economic models used in the evaluation of osteoporotic fracture preventions. Electronic searches within MEDLINE and EMBASE were carried out using a predefined search strategy. Inclusion and exclusion criteria were used to select relevant studies. References listed of included studies were searched to identify any potential study that was not captured in our electronic search. Data on country, interventions, type of fracture prevention, evaluation perspective, type of model, time horizon, fracture sites, expressed costs, types of costs included, and effectiveness measurement were extracted. Seventy-four models were described in 104 publications, of which 69% were European. Earlier models focused mainly on hip, vertebral, and wrist fracture, but later models included multiple fracture sites (humerus, pelvis, tibia, and other fractures). Modeling techniques have evolved from simple decision trees, through deterministic Markov processes to individual patient simulation models accounting for uncertainty in multiple parameters. Treatment continuance has been increasingly taken into account in the models in the last decade. Models have evolved in their complexity and emphasis, with medical continuance becoming increasingly recognized as a contributor to health and economic outcomes. This evolution may be driven in part by the desire to capture all the important differentiating characteristics of medications under scrutiny, as well as the advancement in epidemiological data relevant to osteoporosis fractures.

How do researchers conceive of spousal grief after cancer? A systematic review of models used by researchers to study spousal grief in the cancer context

Although spouses bereaved after cancer are considered vulnerable people, there have been few empirical studies to explore grief specifically in this context. Using PsycINFO, Medline, and the PRISMA statement, we systematically searched the literature by intersecting 'cancer' and 'grie*', 'cancer' and 'bereave*', and 'cancer' and 'mourn*'. Gathering 76 studies (2000-2013) that met the inclusion criteria for bereavement in adulthood, bereavement of an adult loved one and evidence-based research, we found the following: Spousal relationships are not systematically examined in the current dominant models of grief. Theoretically derived determinants of spousal grief after cancer and empirically derived ones converge toward the necessity to include the caregiving experience as determining grief reactions. A growing body of literature concerning prolonged grief disorders now provides integrative reflections regarding the characteristics of spousal loss, predictors, and associated therapeutic interventions in the cancer context. Few empirical studies (20 of 76) target spousal bereavement specifically after cancer. The process of adaptation to loss is usually decontextualized, removing any consideration of the relationship to the deceased or the experience of caregiving and dying. Our findings suggest that this topic warrants more studies that use both prospective and mixed methodologies, as well as explore typical grief needs and experiences of bereaved spouses.

The roles of models in speech communication research

The use of models is a key to development of science and technology. Only through modeling can one test various ideas, hypotheses, and theories against what one observes in nature. This paper first gives a systematic review of models that have been developed in the past on various aspects of speech communication, both between humans and between human and machine. These include speech production models, speech acoustics models, speech perception models, as well as language models and dialogue models. It will then describe briefly some of the models developed by the current author. Finally, it will discuss those aspects that have not been modeled so far, and present the author’s prospects on how to model them. This paper is dedicated to Manfred Schroeder, whose distinguished contributions in many areas of acoustics were enlightening to a large number of fellow researchers.
