Deformation Models

The Interferometric Synthetic Aperture Radar (InSAR) technique has been widely used to obtain the ground surface deformation of geohazards (e.g., mining subsidence and landslides). As one of the inherent errors in the interferometric phase, the digital elevation model (DEM) error is usually estimated with the help of an a priori deformation model. However, it is difficult to determine an a priori deformation model that can fit the deformation time series well, leading to possible bias in the estimation of DEM error and the deformation time series. In this paper, we propose a method that can construct an adaptive deformation model, based on a set of predefined functions and the hypothesis testing theory in the framework of the small baseline subset InSAR (SBAS-InSAR) method. Since it is difficult to fit the deformation time series over a long time span by using only one function, the phase time series is first divided into several groups with overlapping regions. In each group, the hypothesis testing theory is employed to adaptively select the optimal deformation model from the predefined functions. The parameters of adaptive deformation models and the DEM error can be modeled with the phase time series and solved by a least square method. Simulations and real data experiments in the Pingchuan mining area, Gaunsu Province, China, demonstrate that, compared to the state-of-the-art deformation modeling strategy (e.g., the linear deformation model and the function group deformation model), the proposed method can significantly improve the accuracy of DEM error estimation and can benefit the estimation of deformation time series.

<b><i>Background:</i></b> Apathy is highly prevalent in dementia and is also seen in mild cognitive impairment and the general population. Apathy contributes to failure to undertake daily activities and can lead to health problems or crises. It is therefore important to assess apathy. However, there is currently no gold standard measure of apathy. A comprehensive systematic review of the measurement properties of apathy scales is required. <b><i>Methods:</i></b> A systematic review was registered with PROSPERO (ID: CRD42018094390). MEDLINE, Embase, PsycINFO, and CINAHL were searched for studies that aimed to develop or assess the validity or reliability of an apathy scale in participants over 65 years, living in the community. A systematic review was conducted in line with the COnsensus-based Standards for the selection of health Measurement INstruments procedure for reviewing patient-reported outcome measures. The studies’ risk of bias was assessed, and all relevant measurement properties were assessed for quality. Results were pooled and rated using a modified Grading of Recommendations Assessment, Development, and Evaluation procedure. <b><i>Results:</i></b> Fifty-seven publications regarding 18 measures and 39 variations met the eligibility criteria. The methodological quality of individual studies ranged from inadequate to very good and measurement properties ranged from insufficient to sufficient. Similarly, the overall evidence for measurement properties ranged from very low to high quality. The Apathy Evaluation Scale (AES) and Lille Apathy Rating Scale (LARS) had sufficient content validity, reliability, construct validity, and where applicable, structural validity and internal consistency. <b><i>Conclusion:</i></b> Numerous scales are available to assess apathy, with varying psychometric properties. The AES and LARS are recommended for measuring apathy in older adults and people living with dementia. The apathy dimension of the commonly used Neuropsychiatric Inventory should be limited to screening for apathy.

Abstract Background Recap of atopic eczema (RECAP) is a patient-reported outcome measure (PROM) assessing eczema control. Long-term control of eczema is one of the four core outcome domains for atopic eczema trials. This instrument has been recently developed in the UK. Objective This study aimed to translate the English RECAP into German and test its content validity in a German population with self-reported atopic eczema. Methods A six-step procedure including two forward and one backward translations, two consensus decisions and an expert review was performed to obtain a German version of RECAP. We conducted semi-standardized cognitive interviews with adults with atopic eczema (n = 7) and parents having children affected by this disease (n = 5). A “think-aloud” method was used and aspects of comprehensibility, comprehensiveness and relevance according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria were examined. Interviews were coded using qualitative content analysis. Results No particular linguistic problems were encountered during forward-backward translation. Minor wording changes were made as required. The title was adjusted to a more familiar German term of the disease (which is ‘Neurodermitis’). The recall period was rephrased from ‘over the last week’ to ‘over the last seven days’ since there was a different cultural understanding of the time frame. Regarding content validity, the items of the German RECAP were considered to be comprehensible, comprehensive and relevant for the participants and parents of affected children. The participants understood the instruction and considered the one-week recall period and the response options as appropriate. Conclusions A German version of RECAP that is linguistically equivalent to the original version is now available but further assessment of its measurement properties is needed.

BackgroundMatching demand and supply in nursing work continues to generate debate. Current approaches focus on objective measures, such as nurses per occupied bed or patient classification. However, staff numbers do not tell the whole staffing story. The subjective measure of nurses’ perceived adequacy of staffing (PAS) has the potential to enhance nurse staffing methods in a way that goes beyond traditional workload measurement or workforce planning methods.ObjectivesTo detect outcomes associated with nurses’ PAS and the factors that influence PAS and to review the psychometric properties of instruments used to measure PAS in a hospital setting.Design and methodsA scoping review was performed to identify outcomes associated with PAS, factors influencing PAS and instruments measuring PAS. A search of PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Business Source Complete and Embase databases identified 2609 potentially relevant articles. Data were independently extracted, analysed and synthesised. The quality of studies describing influencing factors or outcomes of PAS and psychometric properties of instruments measuring PAS were assessed following the National Institute for Health and Care Excellence quality appraisal checklist and the COnsensus-based Standards for the selection of health Measurement INstruments guidelines.ResultsSixty-three studies were included, describing 60 outcomes of PAS, 79 factors influencing PAS and 21 instruments measuring PAS. In general, positive PAS was related to positive outcomes for the patient, nurse and organisation, supporting the relevance of PAS as a staffing measure. We identified a variety of factors that influence PAS, including demand for care, nurse supply and organisation of care delivery. Associations between these factors and PAS were inconsistent. The quality of studies investigating the development and evaluation of instruments measuring PAS was moderate.ConclusionsMeasuring the PAS may enhance nurse staffing methods in a hospital setting. Further work is needed to refine and psychometrically evaluate instruments for measuring PAS.

The measurement of outcomes is key in evaluating healthcare or research interventions in inflammatory bowel disease (IBD). In patient-centred care, patient-reported outcome measures (PROMs) are central to this evaluation. In this review, we provide an overview of validated, adult disease-specific PROMs developed for use in IBD. Our aim is to assist clinicians and researchers in selection of PROMs to measure outcomes in their patient cohort. The Consensus-based Standards for the Selection of Health Measurement Instruments database of systematic reviews was the primary resource used to identify PROMs used in IBD. Search terms were ‘Crohn’s disease’, ‘ulcerative colitis’, and ‘IBD’. Seven systematic reviews were identified from this search. In addition, the publication by the IBD Core Outcome Set Working Group was used to identify further PROMs. Three systematic reviews were excluded as they did not meet the inclusion criteria. From the five included systematic reviews, we identified 21 PROMs and their shortened versions. In conclusion, it does not appear that any one PROM is entirely suitable for both research and clinical practice. Overall, the IBDQ-32 is most widely used in research but has the limitation of cost, whereas the IBD-Control has been recommended in the clinical core outcome set.

IntroductionNursing research competence of nursing personnel has received much attention in recent years, as nursing has developed as both an independent academic discipline and an evidence-based practiing profession. Instruments for appraising nursing research competence are important, as they can be used to assess nursing research competence of the target population, showing changes of this variable over time and measuring the effectiveness of interventions for improving nursing research competence. There is a need to map the current state of the science of the instruments for nursing research competence, and to identify well validated and reliable instruments. This paper describes a protocol for a scoping review to identify, evaluate, compare and summarise the instruments designed to measure nursing research competence.Methods and analysisThe scoping review will be conducted following Arksey and O’Malley’s methodological framework and Levac et al’s additional recommendations for applying this framework. The scoping review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. The protocol is registered through the Open Science Framework (https://osf.io/ksh43/). Eight English databases and two Chinese databases will be searched between 1 December 2020 and 31 December 2020 to retrieve manuscripts which include instrument(s) of nursing research competence. The literature screening and data extraction will be conducted by two researchers, independently. A third researcher will be involved when consensus is needed. The COnsensus-based Standards for the selection of health Measurement INstruments methodology will be used to evaluate the methodological quality of the included studies on measurement properties of the instruments, as well as the quality of all the instruments identified.Ethics and disseminationEthical approval is not needed. We will disseminate the findings through a conference focusing on nursing research competence and publication of the results in a peer-reviewed journal.

Abstract Background Ankle fractures are painful and debilitating injuries that pose a significant burden to society and healthcare systems. Patient reported outcome measures (PROMs) are commonly used outcome measures in clinical trials of interventions for ankle fracture but there is little evidence on their validity and reliability. This systematic review aims to identify and appraise evidence for the measurement properties of ankle specific PROMs used in adults with an ankle fracture using Consensus Based Standards for the Selection of Health Measurement Instrument (COSMIN) methodology. Methods We searched MEDLINE, Embase and CINAHL online databases for evidence of measurement properties of ankle specific PROMs. Articles were included if they assessed or described the development of the PROM in adults with ankle fracture. Articles were ineligible if they used the PROM to assess the measurement properties of another instrument. Abstracts without full articles and conference proceedings were ineligible, as were articles that adapted the PROM under evaluation without any formal justification of the changes as part of a cross-cultural validation or translation process. Two reviewers completed the screening. To assess methodological quality we used COSMIN risk of bias checklist and summarised evidence using COSMIN quality criteria and a modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Two reviewers assessed the methodological quality and extracted the data for a sample of articles. Results The searches returned a total of 377 articles. From these, six articles were included after application of eligibility criteria. These articles evaluated three PROMs: A-FORM, OMAS and AAOS. The A-FORM had evidence of a robust development process within the patient population, however lacks post-formulation testing. The OMAS showed sufficient levels of reliability, internal consistency and construct validity. The AAOS showed low quality evidence of sufficient construct validity. Conclusions There is insufficient evidence to support the recommendation of a particular PROM for use in adult ankle fracture research based on COSMIN methodology. Further validation of these outcome measures is required in order to ensure PROMs used in this area are sufficiently valid and reliable to assess treatment effects. This would enable high quality, evidenced-based management of adults with ankle fracture.

Abstract Background In the production of ankle-foot orthoses and in-shoe foot orthoses, lower leg morphology is traditionally captured using a plaster cast or foam impression box. Plaster-based processes are a time-consuming and labour-intensive fabrication method. 3D scanning is a promising alternative, however how these new technologies compare with traditional methods is unclear. The aim of this systematic review was to compare the speed, accuracy and reliability of 3D scanning with traditional methods of capturing foot and ankle morphology for fabricating orthoses. Methods PRISMA guidelines were followed and electronic databases were searched to March 2020 using keywords related to 3D scanning technologies and traditional foot and ankle morphology capture methods. Studies of any design from healthy or clinical populations of any age and gender were eligible for inclusion. Studies must have compared 3D scanning to another form of capturing morphology of the foot and/or ankle. Data relating to speed, accuracy and reliability as well as study design, 3D scanner specifications and comparative capture techniques were extracted by two authors (M.F. and Z.W.). Study quality was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) and Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN). Results Six articles met the inclusion criteria, whereby 3D scanning was compared to five traditional methods (plaster cast, foam impression box, ink footprint, digital footprint and clinical assessment). The quality of study outcomes was rated low to moderate (GRADE) and doubtful to adequate (COSMIN). Compared to traditional methods, 3D scanning appeared to be faster than casting (2 to 11 min vs 11 to 16 min). Inter-rater reliability (ICC 0.18–0.99) and intra-rater reliability (ICCs 0.25–0.99) were highly variable for both 3D scanning and traditional techniques, with higher agreement generally dependent on the foot parameter measured. Conclusions The quality and quantity of literature comparing the speed, accuracy and reliability of 3D scanning with traditional methods of capturing foot and ankle morphology is low. 3D scanning appears to be faster especially for experienced users, however accuracy and reliability between methods is variable.
