    Application of Portfolio Theory to Healthcare Capacity Management2021In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 18, no 2, p. 1-9, article id 659Article in journal (Refereed)
    Abstract [en]

    Healthcare systems worldwide are faced with continuously increasing demand for care, while simultaneously experiencing insufficient capacity and unacceptably long patient waiting times. To improve healthcare access and availability, it is thus necessary to improve capacity utilization and increase the efficiency of existing resource usage. For this, variations in healthcare systems must be managed judiciously, and one solution is to apply a capacity pooling approach. A capacity pool is a general, collaborative capacity that can be allocated to parts of the system where the existing workload and demand for capacity are unusually high. In this study, we investigate how basic mean-variance methodology from portfolio theory can be applied as a capacity pooling approach to healthcare systems. A numerical example based on fictitious data is used to illustrate the theoretical value of using a portfolio approach in a capacity pooling context. The example shows that there are opportunities to use capacity more efficiently and increase service levels, given the same capacity, and that a mean-variance analysis could be performed to theoretically dimension the most efficient pooling organization. The study concludes with a discussion regarding the practical usefulness of this methodology in the healthcare context.

    Creating Short-Term Volume Flexibility in Healthcare Capacity Management2020In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, no 22, article id 8514Article in journal (Refereed)
    Abstract [en]

    It is well-known that unpredictable variations in supply and demand of capacity inhealthcare systems create the need for flexibility. The main tools used to create short-term volume flexibility in the healthcare system include overtime, temporary staff from internal calling lists, moving staff across units, internal staffing pools, external staffing agencies, queuing patients, and purchasing care from external providers. We study the creation of short-term volume flexibility in healthcare systems to manage short-term capacity losses and demand fluctuations. A questionnaire was developed and distributed among healthcare managers in the Region Västra Götaland healthcare system. Respondents were asked to what extent they used each tool to create short-term flexibility in capacity. Data were analyzed using multiple regression analysis. Several significant tendencies were found, including that acute units use overtime and internal staffing pools to a larger extent, and queuing patients and external providers to a lesser extent than planned units. The prerequisites and required managerial approaches used to efficiently manage aggregate capacity in the system differ substantially between different parts of the system. These differences must be addressed when, for example, capacity pools are considered. These results serve as a stepping stone towards a more thorough understanding of efficient capacity management in healthcare systems.

    Staff pooling in healthcare systems–results from a mixed-methods study2024In: Health Systems, ISSN 2047-6965, E-ISSN 2047-6973, Vol. 13, no 1, p. 31-47Article in journal (Refereed)
    Abstract [en]

    This study examines how staff pooling can be used to create a higher service level at a predetermined total capacity in the healthcare sector. We develop new empirical knowledge through a systematic empirical study, using a mixed-methods approach, with a preliminary interview study followed by a principal quantitative survey study, with data from a multihospital system. The purpose was to explore practical barriers for a staff pooling strategy in healthcare systems. Three barriers were identified:recruitment difficulties, community view, and specialisation. Significant differences in perceived height among these barriers were found. The results from this study have important managerial implications for healthcare systems when implementing a staff pooling approach. This study contributes to the existing literature since, to the best of our knowledge, no previous research has been done where barriers to staff pools are systematically identified using a holistic approach that includes all healthcare professions in a multihospital system.

    Quantifying BIM investment value:: a systematic review2024In: Journal of Engineering, Design and Technology, ISSN 1726-0531, E-ISSN 1758-8901, p. 1-20Article in journal (Refereed)
    Abstract [en]

    Purpose –

    Perceived benefits of building information modelling (BIM) have been discussed for some time, but cost–benefit benchmarking has been inconsistent. The purpose of this paper is to investigate BIM feasibility and evaluate investment worth to elucidate and develop the current understanding of BIM merit. The aim of the study is to propose a research agenda towards a more holistic perspective of BIM use incorporating quantifying investment return.

    Design/methodology/approach –

    An in-depth examination of research patterns has been conducted to identify challenges in the assessment of the investment value and return on investment (ROI) for BIM in the construction industry. A total of 75 research articles were considered for the final literature review. An evaluation of the literature is conducted using a combination of bibliometric analysis and systematic reviews.

    Findings –

    This study, which analysed 75 articles, unveils key findings in quantifying BIM benefits, primarily through ROI calculation. Two major research gaps are identified: the absence of a standardized BIM ROI method and insufficient exploration of intangible benefits. Research focus varies across phases, emphasizing design and construction integration and exploring post-construction phases. The study categorizes quantifiable factors, including productivity, changes and rework reduction, requests for information reduction, schedule efficiency, safety, environmental sustainability and operations and facility management. These findings offer vital insights for researchers and practitioners, enhancing understanding of ’BIM’s financial benefits and signalling areas for further exploration in construction.

    Originality/value –

    The ’study’s outcomes offer the latest insights for researchers and practitioners to create effective approaches for quantifying ’BIM’s financial benefits. Additionally, the proposed research agenda aims to improve the current limited understanding of BIM feasibility and investment worth evaluation. Results of the study could assist practitioners in overcoming limitations associated with BIM investment and economic evaluations in the construction industry.

    Supply Chain Digitalization in the Wood Manufacturing Industry: A Bibliometric Literature Review2022In: Advances in Transdisciplinary Engineering, ISSN 2352-751X, Vol. 21, p. 617-628Article in journal (Refereed)
    Abstract [en]

    Abstract. The wood manufacturing industry has been described as slow in adopting

    efficiency increasing activities in its operations and supply chain, the industry is still

    facing challenges relating to digitalization such as fragmentation, poor traceability,

    and lack of real-time information. The integration of industry 4.0 technologies can

    enhance the supply chain performance in terms of efficiency, collaboration, quality,

    and transparency. This paper aims to evaluate the current status of digitalization in

    supply chains, by analysing the existing literature and mapping research trends. in an

    aim to create a clearer vision of the current state of digitalization in supply chains in

    general and focusing on the wood manufacturing supply chain in particular, the

    results of the literature review will be used to develop a comprehensive framework

    for future research direction, to fully achieve the benefits of supply chain 4.0 in the

    wood manufacturing industry. This framework serves as a departure point to continue

    explaining and observing the best way to accelerate and implement Supply Chain 4.0

    practices for digitalized supply chain management while focusing specifically on the

    wood manufacturing industry. To achieve the overall purpose, a literature review of

    the key literature from 2016 to 2021 has been performed. using a bibliometric and

    content review analysis, the results shed light on various technologies and their

    applications within supply chains and identify research gaps especially between

    theoretical frameworks and actual implementation. This paper provides a conceptual

    framework to further aid researchers in the exploration of knowledge regarding the

    most current trends in Supply Chain 4.0 and its applications in the wood

    manufacturing industry compared to other advanced industries, as well as the

    directions of the new research in the wood manufacturing Supply Chain 4.0.

    The Interplay Between BIM Implementation Level and Perceived Benefits: Insights from Industry Practitioners2024In: Sustainable Production through Advanced Manufacturing, Intelligent Automation and Work Integrated Learning: Proceedings of the 11th Swedish Production Symposium (SPS2024) / [ed] Joel Andersson, Shrikant Joshi, Lennart Malmsköld, Fabian Hanning, IOS Press , 2024, p. 370-382Chapter in book (Refereed)
    Abstract [en]

    This research delves into the tangible economic impact of Building Information Modelling within the Swedish construction industry, with a particular focus on exploring the relationships among the level of BIM implementation, company size, and the perceived benefits derived from BIM.

    The study's methodology involved conducting a questionnaire survey, from which a dataset of 128 responses was collected for comprehensive analysis. The study's findings challenge prevailing assumptions by suggesting that the size of a company does not necessarily dictate its likelihood of implementing BIM. This contradicts earlier notions that larger companies have a more significant propensity for BIM adoption. Additionally, the research uncovers a positive correlation between higher levels of BIM implementation and the realization of greater benefits. This correlation underscores the potential of BIM in significantly enhancing construction project outcomes. By bridging empirical insights from industry professionals and a robust questionnaire survey, this study provides valuable contributions to the understanding of how BIM can improve performance in the construction sector. 

    These results emphasize the importance of considering BIM's potential benefits beyond the scope of company size and offer fresh perspectives on the dynamics between BIM implementation and perceived advantages in the construction project context.

    Digital transformation of the wood construction supply chain through building information modelling: current state of practice2023In: Construction Innovation, ISSN 1471-4175, E-ISSN 1477-0857, Vol. 24, no 7, p. 273-291Article in journal (Refereed)
    Abstract [en]

    Purpose: This study aims to present a state-of-the-art review of building information modelling (BIM) in the Swedish construction practice with a focus on wood construction. It focuses on examining the extent, maturity and actual practices of BIM in the Swedish wood construction industry, by analysing practitioners’ perspectives on the current state of BIM and its perceived benefits. Design/methodology/approach: A qualitative approach was selected, given the study’s exploratory character. Initially, an extensive review was undertaken to examine the current state of BIM utilisation and its associated advantages within the construction industry. Subsequently, empirical data were acquired through semi-structured interviews featuring open-ended questions, aimed at comprehensively assessing the prevailing extent of BIM integration within the Swedish wood construction sector. Findings: The research concluded that the wood construction industry in Sweden is shifting towards BIM on different levels, where in some cases, the level of implementation is still modest. It should be emphasised that the wood construction industry in Sweden is not realising the full potential of BIM. The industry is still using a combination of BIM and traditional methods, thus, limiting the benefits that full BIM implementation could offer the industry. Originality/value: This study provided empirical evidence on the current perceptions and state of practice of the Swedish wood construction industry regarding BIM maturity. © 2023, Lina Gharaibeh, Sandra Matarneh, Kristina Eriksson and Björn Lantz.

    An Empirical Analysis of Barriers to Building Information Modelling (BIM) Implementation in Wood Construction Projects: Evidence from the Swedish Context2022In: Buildings, E-ISSN 2075-5309, Vol. 12, no 8, p. 1067-1067Article in journal (Refereed)
    Abstract [en]

    Building information modelling is gradually being recognised by the architecture, engineering, construction, and operation industry as a valuable opportunity to increase the efficiency of the built environment. Focusing on the wood construction industry, BIM is becoming a necessity; this is due to its high level of prefabrication and complex digital procedures using wood sawing machines and sophisticated cuttings. However, the full implementation of BIM is still far from reality. The main objective of this paper is to explore the barriers affecting BIM implementation in the Swedish construction industry. An extensive literature review was conducted to extract barriers hindering the implementation of BIM in the construction industry. Secondly, barriers to the implementation of BIM in the wood construction industry in Sweden were extracted using the grounded theory methodology to analyse expert input on the phenomenon of low BIM implementation in the wood construction industry in Sweden. Thirty-four barriers were identified. The analysis of this study also led to the development of a conceptual model that recommended solutions to overcome the barriers identified to help maximise BIM implementation within the wood construction industry. Identifying the main barriers affecting BIM implementation is essential to guide organisational decisions and drive policy, particularly for governments that are considering articulating regulations to expand BIM implementation.

    Hospital Staffing during the COVID-19 Pandemic in Sweden.2022In: Healthcare, E-ISSN 2227-9032, Vol. 10, no 10, article id 2116Article in journal (Refereed)
    Abstract [en]

    Staff management challenges in the healthcare system are inherently different during pandemic conditions than under normal circumstances. Surge capacity must be rapidly increased, particularly in the intensive care units (ICU), to handle the increased pressure, without depleting the rest of the system. In addition, sickness or fatigue among the staff can become a critical issue. This study explores the lessons learned by first- and second-line managers in Sweden with regard to staff management during the COVID-19 pandemic. A mixed-methods approach was used, with preliminary qualitative interview (n = 38) and principal quantitative questionnaire (n = 272) studies, based on principal component and multiple regression analyses. The results revealed that the pandemic created four types of challenges relating to staff management: staff movement within hospitals; addition of external staff; addition of hours for existing staff through overtime and new shift schedules; and avoidance of lost hours due to sickness or fatigue. Furthermore, the effects of these managerial challenges were different in the first wave than in later waves, and they significantly differed between the ICU and other units. Therefore, a greater proactive focus on staff management would be beneficial in future pandemic situations.
