Artificial Intelligence: problems of civil law qualification
Authors: Vasilevskaya L. Ju.
Published: August 2023

Following the methodology of civil research, the concept of artificial intelligence is analyzed and the conclusion about the fallacy of recognizing the legal personality of artificial intelligence is argued. Artificial intelligence as a result of complicated programming is a complex object of civil rights, which includes various structural elements — the results of intellectual activity. The mechanism of acquiring the right to use the results of intellectual activity included in a complex object by a person who organized the creation of artificial intelligence is considered. The essence of legislative exceptions from the general rules on agreement on the alienation of exclusive rights and license agreements in relation to artificial intelligence is analyzed. The conclusion is substantiated that in the absence of regulation of relations on the acquisition of the right to a complex object, it should be provided for: an agreement between the person who organized the creation of artificial intelligence and each of the right holders of the result of intellectual activity that is part of artificial intelligence, or a special condition provided for in the agreement on the alienation of the exclusive right to the result of intellectual activity in as part of an artificial intelligence or a license agreement with each right holder. The conclusion is reasoned that the person who organized the creation of artificial intelligence, in the presence of the considered legal grounds, acquires not only the rights to the relevant results of intellectual activity — structural elements of artificial intelligence, but also the right to the entire artificial intelligence as a whole.
The status of a family member and its impact on participation in civil legal relations
Authors: Kasatkina A. Yu.
Published: August 2023

The article examines the issue of participation of family members in civil legal relations. Cases are considered when the status of a family member is the basis for the emergence, change and termination of certain rights and obligations. The status of a family member gives such a person rights and establishes duties; provides for prohibitions and restrictions; benefits, etc. The problem of determining the status of a family member is also analyzed as a solution to legal relations in connection with the presence of such phenomena as family interest, which is a manifestation of the peculiarity. Due to the fact that in this case there is a clash of civil law and family law mechanisms for the exercise of rights, when the provision that citizens (individuals) acquire and perceive situations with their civil rights of their will and in the interests (paragraph 2 of Art. 1 of the Civil Code of the Russian Federation) adoption of the provisions of family law on the resolution of intra-family issues by mutual agreement. It is concluded that the purpose of legislative changes should be to maintain a balance between the rights and interests of an individual and the rights and interests of the family and family member as a subject of rights
How a Game Theoretic Approach Can Minimize the Cost of Train Passenger Services: An Intermodal Competition between Rail and Road Transport
Authors: Yangailo Tryson
Published: August 2023

Game theory models provide very powerful tools for evaluating strategies that are beneficial to both rail and road operators competing for passengers on parallel routes. This study examines how game theory can help rail operators who are incurring losses on passenger transport to identify strategies that can minimise costs, using the methodology of dual linear programming to analyse strategies. In identifying the best strategies for minimising costs for the railway operator, the best strategies for maximising profits for the road operators are also identified. The game model is set up between two passenger transport operators (rail and road) and is based on the income earned by the road operators from passengers. This study illustrates the following: how the strategies of the two competitors (rail and road) are determined; the formation of the payoff matrix and the presentation of the mathematical problem for the two competitors; and the results and verification of the best strategies for both competitors. The Leonid Hurwicz criterion was used to verify the optimal strategies.
Predictive Models for Seismic Source Parameters Based on Machine Learning and General Orthogonal Regression Approaches

Published: August 2023

Two sets of predictive models are developed based on the machine learning (ML) and general orthogonal regression (GOR) approaches for predicting the seismic source parameters including rupture width, rupture length, rupture area, and two slip parameters (i.e., the average and maximum slips of rupture surface). The predictive models are developed based on a compiled catalog consisting of 1190 sets of estimated source parameters. First, the Light Gradient Boosting Machine (LightGBM), which is a gradient boosting framework that uses tree-based learning algorithms, is utilized to develop the ML-based predictive models by employing five predictor variables consisting of moment magnitude (Mw), hypocenter depth, dip angle, fault-type, and subduction indicators. It is found that the developed ML-based models exhibit good performance in terms of predictive efficiency and generalization. Second, multiple source-scaling models are developed for predicting the source parameters based on the GOR approach, in which each functional form has one predictor variable only, that is, Mw. The performance of the GOR-based models is compared with existing source-scaling relationships. Both sets of the models developed are applicable in estimating the five source parameters in earthquake engineering-related applications.

Authors: Sehrawat Roopali , Bansal Nalini , Srivastava Ajitabh , Malik Dharmender , Vij Vivek
Published: August 2023

Basidiobolus ranarum is known to cause subcutaneous mycoses; however, rare cases of hepatic and gastrointestinal involvement by basidiobolomycosis have been reported. Hepatic basidiobolomycosis may be confused with a carcinoma on imaging, and histological examination and fungal culture can help distinguish between these two. We report a rare case of basidiobolomycosis in a 16-year-old male with liver and gastrointestinal involvement.

Published: August 2023

El análisis de riesgos se encuentra en el corazón de las asociaciones público-privadas (APP), que en esencia son un mecanismo contractual para compartir riesgos entre el sector público y el privado en relaciones de largo plazo a fin de proveer servicios de infraestructura de manera más eficiente. Este libro explica la gestión integral de los pasivos contingentes vinculados a las APP, es decir, de los riesgos cuya probabilidad de ocurrencia y coste esperado son inciertos. Los pasivos contingentes han sido con demasiada frecuencia el punto débil de las APP, generando graves problemas fiscales y deslegitimando la colaboración público-privada en general. Este libro desarrolla las distintas etapas de la gestión de riesgos contingentes, poniendo especial énfasis en su medición, contabilización y reporte. En particular, se presenta la manera de medir los riesgos de sobrecostes, de demanda, de tipo de cambio y legales, así como los de renegociación y terminación anticipada, en los cuales la medición es un paso fundamental para diseñar instrumentos de gestión de riesgos a través de fondos de contingencias o garantías. Este libro también se apoya en una herramienta en Excel/VBA para facilitar el cálculo de la pérdida esperada en cada pasivo contingente analizado. La publicación persigue el propósito de contribuir a generar mejores proyectos APP y es una fuente de conocimiento valiosa para los especialistas en APP que trabajan en ministerios de economía, finanzas y/o hacienda, unidades de APP y contralorías, así como para cualquier profesional del ámbito de la infraestructura interesado en un análisis y gestión rigurosos de los riesgos.

Authors: Araújo Nelma Mirian Chagas de , Meira Igor De Araújo
Published: August 2023

O volume de obras de edificações no Brasil tem crescido a passos largos nos últimos anos, impulsionado pelos megaeventos que serão realizados no país neste ano (Copa Mundial de Futebol) e em 2016 (Olimpíadas), bem como por programas patrocinados pelo governo federal, a exemplo do PAC (Programa de Aceleração do Crescimento) e do Programa Minha Casa Minha Vida. Esse cenário tem levado as empresas construtoras a implementarem sistemas de planejamento e controle que auxiliem na tomada de decisões, levando-se em conta o mercado cada vez mais competitivo, no qual os custos de construção têm oscilado de forma diferenciada e assustadora. O presente artigo, oriundo de um acompanhamento sistemático de dados fornecidos pela Editora PINI, mês a mês, apresenta um diagnóstico analítico, sob o ponto de vista econômico, da evolução dos custos de construção praticados nas capitais nordestinas no período de janeiro/2004 a dezembro/2013. Trata-se de uma pesquisa bibliográfica e documental, quanto aos procedimentos técnicos. Como resultados, são apresentadas séries históricas de dados, relativas a uma década e a todas as capitais dos estados nordestinos, e análises específicas da evolução dos custos na cidade de João Pessoa, nas quais também são utilizados dados fornecidos pelo Sinduscon-JP (Sindicato da Indústria da Construção Civil de João Pessoa).

Published: August 2023

Um sistema de aquecimento solar de água (SAS) é um dispositivo que disponibiliza a energia térmica da radiação solar incidente para o aquecimento de água. O aproveitamento da energia solar em edificações reduz o consumo elétrico. Nesta pesquisa, uma análise técnica e da viabilidade econômica foi realizada em um sistema usando energia solar e gás como fontes energéticas num edifício residencial. O sistema foi estudado operando com 47 coletores solares planos, 2 reservatórios térmicos de 5.000 litros cada, convecção forçada e um sistema auxiliar com 4 aquecedores de passagem a gás. Uma análise técnica durante 12 meses mostrou que o sistema operou com fração solar entre 48-88% e eficiência térmica entre 47-73%. Na análise econômica foram empregados métodos da matemática financeira, como Valor Presente Líquido (VPL), Taxa Interna de Retorno (TIR) e Payback. Os dados coletados demonstraram que o SAS com apoio a gás mostrou-se viável, pois apresentou VPL positivo, TIR superior à taxa de atratividade e recuperação do investimento (Payback) em menos de 8 anos para vida útil de 20 anos. Também foram monitoradas as temperaturas do SAS, mostrando que a falta de manutenção pode gerar grandes perdas de energia e elevado custo com consumo de gás.

Published: August 2023

El uso de contratos estandarizados en la implementación de proyectos de infraestructura pública ha marcado un hito en las políticas de inversión en infraestructura en el Perú. Desde el año 2019, han sido los contratos New Engineering Contract (NEC) los que han tenido un uso relevante en proyectos de construcción en los que una de las partes contractuales es el Estado peruano. A partir de ello, surge la necesidad de estudiar la gestión del riesgo de financiamiento y su regulación específica en este tipo de contratos. Dada la trascendencia de una correcta gestión del riesgo de financiamiento en un contrato NEC, en el presente artículo se analizarán los deberes y obligaciones relacionadas, así como el origen y las consecuencias del conocido ‘‘desfinanciamiento’’ o ‘‘desequilibrio económico financiero’’ de un proyecto de construcción.

DETERMINING THE OPTIMAL MODEL FOR ENGAGING HUMAN RESOURCES AMONG THE SPECIAL POLICE UNITS ACCORDING TO THE PSYCHOPHYSICAL CHARACTERISTICS
Authors:   Faculty of Security – Skopje, Ivanovski Jonche
Published: August 2023

Police work is a complex type of profession in which special police units have the duty to perform the most complex, difficult and risky security tasks. In order to successfully solve security problems, it is very important that the members of these units constantly maintain high level of combat readiness and training. The basic condition for good organization, efficient training and action of the special units is to place each member in the place where, according to his psycho-physical abilities and characteristics, they can contribute the most to the performance of their duties. Taking into consideration the nature of the tasks and their specificity, human resource management is a very complex process because the senior staff should show an enviable level of knowledge and readiness for an appropriate selection. To help this commitment and in order to rationalize the procedure for proper structuring of quality and efficient formations, the labor of 80 members of the Rapid Deployment Unit was tested, i.e. their motor, morphological and psychological characteristics, in order to form a database and to determine criteria for psychophysical engagement of human potential. Based on the conducted statistical analyzes and procedures, it was concluded that in general, the tested empirical model for psychophysical engagement of human potentials in the unit meets the minimum quality criteria, but still, in order to meet the specific safety requirements, it is necessary that the psychophysical capabilities and characteristics of members are at least one level higher on the grading scale. Keywords: police profession, special police units, human potential, psychological characteristics, statistical analyzes and procedures

Published: August 2023

The coronavirus pandemic is more global, dramatic, and unusual than any crisis we have seen in a long time. It has not only seriously threatened human life but also severely impacted the world economy and international relations. Following the pandemic, global affairs as well as state-to-state relationships are witnessing major, even qualitative, changes. The article analyzes the relations of two major powers, the United States of America and China, the two most important players on the world stage in the era of COVID19 and its implication of the world order. The global impact of the coronavirus pandemic poses two interconnected questions: Is this a historic moment when the world will change permanently? Will there be a lasting impact on geopolitics globally? A definite answer to these questions is not yet in sight. However, the emerging political debate on the impact of the pandemic could help bring about clearer predictions about how the world will evolve in the post-Covid-19 period.

The thematic framework of this paper indicates the fact that the world we live in today will not be the same tomorrow. Globalisation is a phenomenon that dominantly marks the time starting from the end of the World War II to the present day and as such shapes the political, economic and social life of the world, unevenly and with different consequences. This universal process, which includes strong political and military connections between people and countries, is gaining in intensity over time, with a profound tendency to cover all spheres of individual and collective existence of the people around the world, changing the rules and norms of behavior, value systems and lifestyles of entire communities. This paper will examine the mutual relation between globalisation and warfare or other conflicts fought in the previous period or that are still being fought, as well as the relation of cause and effect between globalisation and warfare over that period, in order to determine whether wars and other conflicts are actually the initial trigger for making the process of globalisation faster and in order to discover in what way they do that. The paper also deals with a historical connection between warfare and globalisation through the impact of historical contradictions on the globalisation directions, and also through the identification of the part of military challenges, risks, and threats in the process of globalisation. Additionally, the paper will consider the impact of military conflicts on globalisation directions by means of foreign interests aimed at limiting the sovereignty of nation states.

Published: August 2023

Bangladesh is committed to perform on Sustainable Development Goals (SDGs) and prioritizing climate change issues to create a safe living and working environment for all. Transport has an enormous contribution to society in functioning our daily life also a cause of environmental degradation. More than 95% of containerized cargo are moving from/to Chattogram Port by using road mode that is liable for Carbon dioxide (CO2) emission, congestion, and high transport cost. Rail intermodal is facing capacity constraints in Dhaka rail Inland Container Depot (ICD), and river intermodal is under-utilized for the shortage of hinterland logistics facilities, the mindset of users, and poor terminal productivity. This research applied the quantitative method to analyze the port throughput of Chattogram Port and its hinterland connectivity by nodes to get innovation and sustainability to identify environmental factors in international freight movement economically. On the basis of a literature review, and explored research gaps before data analysis, it is clear that environmental factors including SDGs are not considered in the inland freight transportation systems of Bangladesh. The research findings alerted that people in the freight movement system do not present a wide awareness of their activities and due diligence to environmental sustainability in creating a wider room for the next generations. The quantitative analysis of port throughput data indicated to increase in the share of intermodal especially river intermodal which has a wider scope to use available river ports in all parts of the country naturally. The practical impact of the research is to formulate a long-term environmental strategy in freight transport, corporate execution by all transport business-oriented companies/organizations, and enabling technologies in inland freight operations and monitoring. Overall, this paper provides a conceptual framework for the environmental sustainability of inland freight transportation systems in Bangladesh in doing international shipping and trade.
Neodymium Nitrate Improves the Germination of Aged Wheat Seeds by Increasing Soluble Substances and Activating Antioxidative and Metabolic Enzymes in Seeds
Authors: Hu Genhai , Zhou Xiuren , Zhu Qidi , Chao Maoni , Fu Yuanzhi , Hu Haiyan
Published: August 2023

Seeds stored for a prolonged period are subject to aging and reduction in germination potential (GP), which will negatively affect seed sales. Rare-earth elements have a synergistic effect on the improvement of seed GP. In this study, we examined the effects of neodymium on biochemical components, the antioxidant protective system, and metabolism-related enzymes during germination of naturally and artificially aged seeds of three wheat cultivars. Seed germination indices, biochemical substance contents, and enzyme activities decreased after seed aging. Soaking seeds in neodymium nitrate solution revived aged wheat seeds at an optimal concentration of 20 µmol/L for 8 h. Soaking in neodymium nitrate solution increased the GP (by 2.25%–60.9%), germination index (by 1.69%–29.2%), and vigor index (by 3.36%–18.7%) of aged seeds. Compared with non-soaked seeds, soaking significantly changed the contents of biochemical substances, and the activities of antioxidant protective enzymes and metabolic enzymes in seedlings were increased. Soaking with neodymium may revive aged seeds by regulating the synthesis of soluble sugars, soluble proteins, chlorophyll, and carotenoids, and decomposing malondialdehyde, in the germinating seed. Root dehydrogenase and amylase showed different responses to the aging modes. The differential responses of root dehydrogenase and amylase may reflect differences in the resistance of enzymes to long-term mild seed aging and short-term severe environmental aging.
The Implications of a Co-Created Software Solution for Mobility in Rural Areas
Authors: Eichholz Lutz
Published: August 2023

This paper explores the challenges of providing services of general interest in rural areas of Germany and proposes co-created mobility software solutions to address the specific needs of these regions. The research is part of the Smarte.Land.Regionen project, which aims to improve digital public services at the district level. Focusing on rural mobility, the paper introduces the concept of ride-sharing benches as a potential solution. Through workshops, surveys and market research, the study identifies barriers to the adoption of ride-sharing benches and investigates factors contributing to their success. The proposed software solution emphasizes user-centered development, geographic location of benches and prioritized matching of passengers. Findings highlight safety concerns, lack of reliability, and the importance of getting people who are theoretically interested in solutions to actively participate in them. The paper emphasizes the importance of collaborative development with county stakeholders. Future research should focus on sustaining and scaling digital solutions, measuring their impact on rural mobility, and ensuring their transferability to other regions. The ultimate goal is to contribute to inclusive and sustainable rural development by improving access to digital public services and promoting the adoption of tailored mobility solutions.

Authors: Ranade Ashish S. , Gandhi Shreyans
Published: August 2023

Case:

A 9-year-old boy presented with a painful, swollen knee. He had a wound on the knee 2 months ago after a fall in contaminated water. At another hospital, this was treated with debridement twice, and the patient received several antibiotics. Imaging showed septic arthritis and epiphyseal osteomyelitis involving the proximal medial tibia. Surgical debridement and joint washout were performed. Fungal cultures grew Scedosporium boydii. Antifungal treatment with voriconazole was given. At a 5-year follow-up, we noticed favorable outcomes without any complications.

Conclusions:

Fungal osteomyelitis because of direct inoculation should be considered a rare differential diagnosis while treating epiphyseal osteomyelitis.
Triceps Rupture After Olecranon Fixation with Proximal Ulna Plate and Suture Augmentation
Authors: Flores Sergio Eduardo , Sheridan Joseph Ryan , Larson Eric Stanley , Immerman Igor
Published: August 2023

Case:

Olecranon fractures treated with proximal ulna plate fixation and repairing the triceps with suture augmentation to the plate decrease the risk of “olecranon escape,” but may lead to failure through triceps rupture. In this case report, a rare complication of triceps rupture occurred, and the patient underwent triceps repair.

Conclusion:

When fixing olecranon fractures, surgeons should minimize triceps dissection for hardware placement. If subjected to significant force, a surgical insult to the tendon footprint for a better plate contact on the bone and the presence of suture augmentation may change the construct failure mechanism and result in triceps rupture as opposed to fracture redisplacement.

Maintaining or increasing production from wells in mature oil reservoirs with high pressure, temperature, brine hardness, and salinity is a significant technological and economic challenge. These wells usually produce with a high gas-oil ratio and large water cuts and often operate with gas lift systems.

This work focuses on the development and application of new multifunctional foaming agents (MFAs) to enhance production from oil wells under these conditions. The MFAs were developed based on molecular design and laboratory studies, which demonstrated that they can be used with water cuts exceeding 30% and in the presence of salinity and hardness levels up to 400,000 ppm and 180,000 ppm, respectively. Furthermore, these agents remain stable at temperatures up to 180°C.

The production/lift efficiency of the MFAs was evaluated using two novel dynamic laboratory methods that are conducted close to the wellhead and at downhole conditions of temperature and pressure, respectively. The experimental results demonstrate a significant enhancement in the liquid production efficiency, with some cases showing an increase from no production to as much as 44% when the MFAs were used.

The laboratory tests were also used to optimize the MFA type and concentration in the design of a field application. The field test was conducted in three oil wells with water cuts ranging from 40% to 90%, depths exceeding 5000 m, bottomhole temperature around 150°C, and brine hardness and salinity up to 180,000 ppm and 310,000 ppm, respectively. This is the first reported field test of MFAs for production enhancement under such challenging conditions.

The MFA was coinjected with gas lift via the annulus. The MFA mixed with reservoir fluids in the tubing and generated foam downhole with concentrations ranging from 160 ppm to 750 ppm. The rheological properties of the foam were designed to prevent pressure losses and the formation of stable foam or emulsions at surface facilities. The field tests demonstrated that the MFA was able to increase oil production at a fixed gas lift injection flow rate. Alternatively, it was able to reduce lift gas consumption while maintaining or even increasing the original oil production.

Geological sensitive areas can be mapped using geological terrain mapping approach because this approach is on site combination of geological and terrain features. The objective of this geological terrain mapping in the Ranau area is to provide systematic geological input for landuse planning through the production of various thematic maps to assist in the planning for the future and for the use as a guideline in the approval of construction projects in the Ranau area as well as would assist local authorities, town planners, architects, engineers and stakeholders to control development to ensure the safety of property and public lives. Ranau is located in the highlands central part of Sabah where seismic activities and geohazard phenomena is active due to its complex geological setting. Past tectonic activity causing the occurrences of complex geological setting and active faults movement in the Ranau region. Some of these faults are active and capable to produce seismic activity at any time. The area traversed by the fault zone is prone to instability particularly the threat of geohazard such as landslides, rock falls, debris flow, soil creep and soil settlement. Due to geohazard threat, thus development planning in the Ranau area should be controlled and managed so that areas that tthat underlain by geologically sensitive can be avoided from being developed. The results of geological terrain mapping in Ranau area showed that 32% had low to moderate geotechnical constraints while 68% had high to very high geotechnical constraints.

To determine the true causes of earth tremors, high resolution maps created from aircraft radiometric datasets were utilized to illustrate the primary lithology and structural features found in the north-central Nigeria. A range of magnetic amplitudes was seen from the Total Magnetic Intensity. This implies that the underlying rocks are at various depths and have variable magnetic mineral contents depending on the type of rock unit. This is confirmed by generated concentration maps of percentage Uranium, Thorium (u/th)Uranium Potassium (u/k) and Thorium Potassium (th/k) these maps showed low to moderate and high concentration of radio-element. Thorium (0 < 6.4ppm to > 31.9ppm), potassium (0% to > 4.1%), uranium (1.14ppm to < 0.76ppm%). respectively in rocks covering the study area. These results revealed that the study area is geologically characterized by granite gneiss, porphyritic granite rock, felsic granitic rock, schist and migmatite gneiss. Thus, these observed changes in the Total Magnetic Intensity (TMI) map with a low to moderate concentration of the radio elements-identified suggest weathering and intense metamorphism, which could be regarded as unstable, allowing for transmission of seismic energy leading to tremor activities in the study area.
Flooding vulnerability in Algiers (Algeria): An Analytic Hierarchy Process

Published: August 2023

Flooding is the second most serious hazard in Algeria, after earthquakes. According to the Civil Protection Services census, the department of Algiers experienced 174 floods between 1946 and 2021, several devastating floods. This study examines Algiers’ vulnerability to flooding using the Hierarchical Multicriteria Analysis (AHP) method, which aggregates eight criteria: altitude distribution, slopes, drainage density, topographic wetness index, land cover and land use, normalized difference vegetation index, soil types, and precipitations. With an accuracy of 85%, the resulting vulnerability map is an essential tool for better risk and land use management. The municipalities most vulnerable to flooding are located in the Mitidja (east of Algiers) and Algiers’ Western Sahel. These areas cover 71.29 km2 (10% of Algiers’ area) and are primarily located in the watersheds of El Harrach, El Hamiz, and Reghaia, while 25.8% of urbanized areas are moderately vulnerable. However, these areas require special attention because of their high population density. Flood risk has undeniably become more frequent and intense due to Algiers’ significant and often anarchic increase in urbanization in recent years, particularly at the edge of the major Wadis beds (nearly half of their watershed area is urbanized). This trend will worsen as extreme weather events increase, necessitating a stricter application of land use planning regulations and prevention, adaptation, and mitigation measures.

Background
This study was a two-year follow-up evaluation of health service use and the cost-effectiveness of a multicomponent general practice intervention targeted at people at high risk of poor health outcomes.
Methods
A two-year follow-up study of a clustered randomised controlled trial was conducted in South Australia during 2018–19, recruiting 1044 patients from three cohorts: children; adults (aged 18–64 years with two or more chronic diseases); and older adults (aged ≥ 65 years). Intervention group practices (n = 10) provided a multicomponent general practice intervention for 12 months. The intervention comprised patient enrolment to a preferred general practitioner (GP), access to longer GP appointments and timely general practice follow-up after episodes of hospital care. Health service outcomes included hospital use, specialist services and pharmaceuticals. The economic evaluation was based on quality-adjusted life years (QALYs) calculated from EuroQoL 5 dimensions, 5 level utility scores and used an A$50,000 per QALY gained threshold for determining cost-effectiveness.
Results
Over the two years, there were no statistically significant intervention effects for health service use. In the total sample, the mean total cost per patient was greater for the intervention than control group, but the number of QALYs gained in the intervention group was higher. The estimated incremental cost-effectiveness ratio (ICER) was A$18,211 per QALY gained, which is lower than the A$50,000 per QALY gained threshold used in Australia. However, the intervention's cost-effectiveness was shown to differ by cohort. For the adult cohort, the intervention was associated with higher costs and lower QALYs gained (vs the total cohort) and was not cost-effective. For the older adults cohort, the intervention was associated with lower costs (A$540 per patient), due primarily to lower hospital costs, and was more effective than usual care.
Conclusions
The positive cost-effectiveness results from the 24-month follow-up warrant replication in a study appropriately powered for outcomes such as hospital use, with an intervention period of at least two years, and targeted to older people at high risk of poor health outcomes.
