Mycobacterium tuberculosis (MTB) is the causative agent of pulmonary tuberculosis. Rapid and accurate diagnosis is crucial to tuberculosis control and prevention. A series of diagnostic methods has been available for MTB detection; however, new rapid, simple and affordable methods are needed. In this study, a multiple cross displacement amplification (MCDA)-based assay was developed to detect the IS6110 gene of the M. tuberculosis complex. Hydroxy naphthol blue (HNB), a colorimetric indicator, was used to detect amplification products...

Multi-criteria decision analysis (MCDA) is an emerging tool that allows the integration of relevant factors for health technology assessment (HTA). This study aims to present a summary of the methodological characteristics of MCDA: definitions, approaches, applications, and implementation stages. A case study was conducted in the São Paulo State Cancer Institute (ICESP) in order to understand the perspectives of decision-makers in the process of drafting a recommendation for the incorporation of technology in the Brazilian Unified National Health System (SUS), through a report by the Brazilian National Commission for the Incorporation of Technologies in the SUS (CONITEC)...

Background and objectives:   MCDA is a decision-making tool with increasing use in the healthcare sector, including HTA (Health Technology Assessment). By applying multiple criteria, including innovation, in a comprehensive, structured and explicit manner, MCDA fosters a transparent, participative, consistent decision-making process taking into consideration values of all stakeholders. This paper by FIFARMA (Latin American Federation of Pharmaceutical Industry) proposes the deliberative (partial) MCDA as a more pragmatic, agile approach, especially when newly implemented...

Off-patent pharmaceuticals (OPPs) represent more than 60% of the pharmaceutical market in many emerging countries, where they are frequently evaluated primarily on cost rather than with health technology assessment. OPPs are assumed to be identical to the originators. Branded and unbranded generic versions can, however, vary from the originator in active pharmaceutical ingredients, dosage, consistency formulation, excipients, manufacturing processes, and distribution, for example. These variables can alter the efficacy and safety of the product, negatively impacting both the anticipated cost savings and the population's health...

BACKGROUND: Multiple criteria decision analysis (MCDA) has appeared as a methodology to address limitations of economic evaluation in health technology assessment (HTA), however there are limited empirical evidence from real world applications. The aim of this study is to test in practice a recently developed MCDA methodological framework known as Advance Value Framework (AVF) through a proof-of-concept case study engaging multiple stakeholders. METHODS: A multi-attribute value theory methodological process was adopted involving problem structuring, model building, model assessment and model appraisal phases...

Glacial Lake Outburst Floods (GLOFs) represent a significant threat in deglaciating environments, necessitating the development of GLOF hazard and risk assessment procedures. Here, we outline a Multi-Criteria Decision Analysis (MCDA) approach that can be used to rapidly identify potentially dangerous lakes in regions without existing tailored GLOF risk assessments, where a range of glacial lake types exist, and where field data are sparse or non-existent. Our MCDA model (1) is desk-based and uses freely and widely available data inputs and software, and (2) allows the relative risk posed by a range of glacial lake types to be assessed simultaneously within any region...

Here, we devised a novel isothermal technique on the basis of standard multiple cross-displacement amplification (MCDA), which is assisted with self-avoiding molecular recognition system (SAMRS) components and antarctic thermal-sensitive uracil-DNA-glycosylase enzyme (AUDG), termed AUDG-SAMRS-MCDA. To enable product detection on the dipsticks, we firstly developed an analysis strategy, which did not require the labelled primers or probes, and thus, the analysis system avoids the false-positive results arising from undesired hybridization (between two labelled primers, or the labelled probe and primer)...

OBJECTIVE: The aim of this study was to investigate the association between abnormal cord insertion and the development of the twin-specific complications, including birthweight discordance, selective fetal growth restriction (sFGR) and twin-to-twin transfusion syndrome (TTTS). METHODS: A single-center cohort study of twin pregnancies. Abnormal cord insertion was defined as either marginal (cord attachment site less than 2cm to the nearest margin of the placental disc) or velamentous (when the umbilical cord was attached to the membrane before reaching the placental disc with clear evidence of vessels traversing the membranes to connect with the placental disc), as described in placental pathology reports...

As healthcare resources become increasingly scarce due to growing demand and stagnating budgets, the need for effective priority setting and resource allocation will become ever more critical to providing sustainable care to patients. While societal values should certainly play a part in guiding these processes, the methodology used to capture these values need not necessarily be limited to multi-criterion decision analysis (MCDA)-based processes including 'evidence-informed deliberative processes.' However, if decision-makers intend to not only incorporates the values of the public they serve into decisions but have the decisions enacted as well, consideration should be given to more direct involvement of stakeholders...

Health technology assessment (HTA) is widely viewed as an essential component in good universal health coverage (UHC) decision-making in any country. Various HTA tools and metrics have been developed and refined over the years, including systematic literature reviews (Cochrane), economic modelling, and cost-effectiveness ratios and acceptability curves. However, while the cost-effectiveness ratio is faithfully reported in most full economic evaluations, it is viewed by many as an insufficient basis for reimbursement decisions...

BACKGROUND: Hand hygiene is one of the most effective attempts to control nosocomial infections, and it is an important measure to avoid the transmission of pathogens. However, the compliance of healthcare workers (HCWs) with hand washing is still poor worldwide. Herein, we aimed to determine the best hand hygiene preference of the infectious diseases and clinical microbiology (IDCM) specialists to prevent transmission of microorganisms from one patient to another. METHODS: Expert opinions regarding the criteria that influence the best hand hygiene preference were collected through a questionnaire via face-to-face interviews...

The challenges of delivering healthcare within budget constraints are ever present. Highly specialised technologies (HSTs) have high costs of provision inevitably contributing to NHS cost pressures. Between 2012-2015 the Welsh Health Specialised Services Committee (WHSSC) developed prioritisation methods to make recommendations for HST funding in Wales. Methods adapted as the process continued but was always evidence based and supported by a prioritisation panel of stakeholders. Methods changed from discreet choice to the Portsmouth Score Card, a simple multi-criteria decision analysis (MCDA) method...

Escalating drug prices have catalysed the generation of numerous "value frameworks" with the aim of informing payers, clinicians and patients on the assessment and appraisal process of new medicines for the purpose of coverage and treatment selection decisions. Although this is an important step towards a more inclusive Value Based Assessment (VBA) approach, aspects of these frameworks are based on weak methodologies and could potentially result in misleading recommendations or decisions. In this paper, a Multiple Criteria Decision Analysis (MCDA) methodological process, based on Multi Attribute Value Theory (MAVT), is adopted for building a multi-criteria evaluation model...

The lately inured § 137 h SGB V aims to assess the benefit of new examination and treatment methods with medical devices of class IIb and III. In the future, the decision on the reimbursement eligibility will be marked by high requirements in terms of documentation of benefits and harm. The objective of benefit assessment is the operationalization of benefit to patients. A comparative determination of benefit enables rational decision by regulatory authorities. The process of benefit assessment should guarantee transparent decision-making, and the underlying medical and health economic fundamentals should be documented...

BACKGROUND: There is a growing body of literature on systematic approaches to healthcare priority setting from various countries and different levels of decision making. This paper synthesizes the current literature in order to assess the extent to which program budgeting and marginal analysis (PBMA), burden of disease & cost-effectiveness analysis (BOD/CEA), multi-criteria decision analysis (MCDA), and accountability for reasonableness (A4R), are reported to have been institutionalized and influenced policy making and practice...

Recent studies have demonstrated an association between congenital Zika virus (ZIKV) infection and microcephaly; however, to date, there have been no reports on the consequences of ZIKV infection on fetuses in twin pregnancies. Herein, we reported on the first case of a monochorionic diamniotic (MCDA) twin pregnancy having ZIKV-related microcephaly. Our findings suggested that, in an MCDA twin pregnancy, the ZIKV may cause infection in both fetuses, resulting in severe abnormalities in the central nervous system due to neural cell destruction and the disruption of the normal development processes of the brain...

PURPOSE: Multiple criteria decision analysis swing weighting (SW) and discrete choice experiments (DCE) are appropriate methods for capturing patient preferences on treatment benefit-risk trade-offs. This paper presents a qualitative comparison of the 2 methods. METHODS: We review and critically assess similarities and differences of SW and DCE based on 6 aspects: comprehension by study participants, cognitive biases, sample representativeness, ability to capture heterogeneity in preferences, reliability and validity, and robustness of the results...

This paper deals with the environmental characterization of a large and densely populated area, with a poor reputation for contamination, considering the contribution of environmental features (air, soil, soil hydraulic and groundwater) and the potential effects on human health. The use of Geographic Information System (GIS) has made possible a georeferenced inventory and, by overlaying environmental information, an operational synthesis of comprehensive environmental conditions. The cumulative effects on environmental features were evaluated, taking into account superposition effects, by means of the Spatial MultiCriteria Decision Analysis (S-MCDA)...
