They also have important implications for resource utilization efficiency and cost containment efforts by healthcare organizations. Effective predictions should consider essential relationships across different variables pertaining to patient demographics, clinical history, injury severity, and physiology. A proposed deep learning–based method incorporates these relationships and can predict LOS more accurately, as demonstrated by a comparative evaluation involving 3722 patients who suffered traumatic fall injuries between 2011 and 2017. The results show the superior performance of the proposed method, relative to eleven prevalent methods that represent different analytics approaches. Our method demonstrates superior predictive performance, as manifested by the highest F-measure values and area under the curve. It is particularly efficacious for patients likely in need of longer LOS, which is relatively more important to physicians and healthcare organizations. This study underscores the value of incorporating important relationships and interactions among distinct patient variables to estimate LOS, with a particular emphasis on the inter-disease relationships, physiology-severity interactions, and patient information in clinical notes. The proposed method can be implemented as a decision support system to enhance physicians' clinical decisions and patient management, and improve healthcare organizations' resource planning and utilization efficiency, with nontrivial cost containment implications.</div></div>","PeriodicalId":55181,"journal":{"name":"Decision Support Systems","volume":"191 ","pages":"Article 114411"},"PeriodicalIF":6.7,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we explore the complementary effects of a specific type of HIT, Clinical Decision Support Systems (CDSS) on cardiac mortality rates (CMR) in hospitals. Though hospital personnel and cardiac medical services (CMS) are pivotal in reducing CMR, CDSS plays a complementary role by providing information and decision support throughout the cardiac care delivery process. Leveraging panel data spanning from 2016 to 2020, our analysis reveals that CDSS complements CMS and hospital personnel in mitigating CMR. These findings provide theoretical insights into the benefits facilitated by CDSS in cardiac care and hold managerial implications for the effective deployment of this technology within hospital settings. Through our analysis, we aim to elucidate the synergistic effects of CDSS, cardiac medical services, and healthcare personnel in improving clinical healthcare outcomes, particularly in the management of cardiac disease.</div></div>","PeriodicalId":55181,"journal":{"name":"Decision Support Systems","volume":"191 ","pages":"Article 114410"},"PeriodicalIF":6.7,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reasons for dissatisfaction include an outsourcing agreement that did not meet expectations, organizational changes, and a loss of control over the business. As a result, companies are rethinking their existing contracts by adopting a backsourcing solution. IS/IT backsourcing refers to the full or partial repatriation of previously outsourced activities. Given the strategic stakes of backsourcing, it is imperative to develop a decision-making process based on a solid framework. Based on an extensive literature review, we propose a design science research (DSR) approach consisting of four artifacts: a set of requirements, a conceptual framework, a decision model, and a prototype to support decision makers considering IS/IT backsourcing issues. A validation is presented, consisting of an illustrative scenario, a logical argument, and an expert evaluation. In addition, the approach was compared with recommendations found in the literature. Finally, the comments of a panel of IS/IT experts were collected. Our decision support system can be used by decision makers to investigate the backsourcing of IS/IT activities, choosing between three scenarios: backsource, renegotiate the contract, or change vendor.</div></div>","PeriodicalId":55181,"journal":{"name":"Decision Support Systems","volume":"189 ","pages":"Article 114379"},"PeriodicalIF":6.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143170850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that suspended users post less frequently after they experience temporary account suspension, but that these users create longer content compared to those users who did not face account suspension. We also find that user characteristics (e.g., platform tenure, prior suspension history) moderate the impact of suspensions on content length and volume. Further, mechanism analyses reveal that content posted by users who experienced temporary account suspension receives more negative reactions from the community after the suspension, even when the content does not violate platform's content contribution guidelines. As a result, suspended users are more likely to leave a platform after the suspension.

Prior studies lack an understanding of how blockchain transparency and information-seeking shape individual decision-making regarding sustainable consumption. In this study, building on signaling theory, we have developed a model to understand how blockchain transparency and the consumers' information-seeking tendencies may reduce sustainable product uncertainty. To analyze our research model, first, we conducted five focus group interviews with 21 participants to understand their information needs while making sustainable consumption decisions in the context of the fashion apparel industry. The results of the focus groups helped us craft a scenario and user interface (UI) for a novel blockchain-based app for sustainable consumption. We then collected data from 282 European consumers and examined direct path coefficients and indirect moderated mediation effects. The findings highlight that blockchain transparency affects the trustworthiness of product sustainability and improves consumer satisfaction, which in turn reduces sustainable product uncertainty. The relationship between blockchain transparency and satisfaction is reduced by information-seeking. This finding implies that the consumers' experience of blockchain transparency in terms of enhanced satisfaction is not always consistent and instead depends on their inclination to seek information.</div></div>","PeriodicalId":55181,"journal":{"name":"Decision Support Systems","volume":"189 ","pages":"Article 114370"},"PeriodicalIF":6.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143169638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
