Viele internationale auswärtige Ämter nutzen die Online-Plattform Twitter mittlerweile als Kanal für Reisewarnungen. Dieser neue Informationskanal erlaubt den Betrieb von Anwendungen, die einem ...breiten Publikum aktuelle, hochqualitative Reiserisikoinformationen zugänglich machen. Unsere explorative Forschung hat das Ziel, die Rolle der Informationsquelle und Zielgruppe einer solchen Anwendung zu untersuchen. Die Resultate unserer Analyse zeigen keine substantiellen Hinweise darauf, dass nutzergenerierte Inhalte per se ungeeignet als Informationsquelle sind. Zusätzlich zeigt unsere Analyse, dass Vielreisende eine besonders interessante Zielgruppe sind.
Online platform Twitter, has been recognized by international foreign offices as an outlet for travel warning. This new channel of information allows for the creation of applications that bring current and high quality travel risk information to the mainstream. Our explorative research aims at investigating the role of the information source and target audience of such an application. The results of our analysis show no substantial evidence that user-generated travel risk information would be per se unsuitable as an information source. Further, our analysis revealed that frequent travelers might be of special interest as a target group for the application.
In order to improve transparency and stabilise health care costs, several countries have decided to reform their healthcare system on the basis of diagnosis-related groups (DRG). DRGs are not only ...used for classifying medical treatments, but also for case-based reimbursement, hence induce active competition among hospitals, forcing them to become more efficient and effective. In consequence, hospitals are investing considerably in process orientation and management. However, to date there is neither a consensus on what capabilities hospitals need to acquire for becoming process-oriented, nor a general agreement on the sequence of development stages they have to traverse. To this end, this study proposes an empirically grounded conceptualisation of process management capabilities and presents a staged capability maturity model algorithmically derived on the basis of empirical data from 129 acute somatic hospitals in Switzerland. The five capability maturity levels start with 'encouragement of process orientation' (level 1), 'case-by-case handling' (level 2), and 'defined processes' (level 3). Ultimately, hospitals can reach the levels 'occasional corrective action' (level 4) and 'closed loop improvement' (level 5). The empirically derived model reveals why existing, generic capability maturity models for process management are not applicable in the hospitals context: their comparatively high complexity on the one hand and their strong focus on topics like an adequate IT integration and process automation on the other make them inadequate for solving the problems felt in the hospital sector, which are primarily of cultural and structural nature. We deem the proposed capability maturity model capable to overcome these shortcomings.
In order to identify and explore the strengths and weaknesses of business intelligence (BI) initiatives, managers in charge need to assess the maturity of their BI efforts. For this, a wide range of ...maturity models has been developed, but these models often focus on technical details and do not address the potential value proposition of BI. Based on an extensive literature review and an empirical study, we develop and evaluate a theoretical model of impact-oriented BI maturity. Building on established IS theories, the model integrates BI deployment, BI usage, individual impact, and organizational performance. This conceptualization helps to refocus the topic of BI maturity to business needs and can be used as a theoretical foundation for future research.
To provide effective care for COVID-19 inpatients, clinical practitioners need systems that monitor patient health and subsequently allow for risk scoring. Existing approaches for risk scoring in ...COVID-19 patients focus primarily on intensive care units with specialized medical measurement devices, but not on hospital general wards.
In this paper, we aim to develop a risk score for COVID-19 inpatients in general wards based on consumer-grade wearables (smartwatches).
Patients wore consumer-grade wearables to record physiological measurements such as heart rate, heart rate variability, and respiration frequency. Based on Bayesian survival analysis, we validate the association between these measurements and the patient outcomes (i.e., discharge or intensive care unit admission). To build our risk score, we generate a low-dimensional representation of the physiological features. Subsequently, a pooled ordinal regression with time-dependent covariates infers the probability of either hospital discharge or intensive care unit (ICU) admission.
We evaluate the predictive performance of our developed system for risk scoring in a single-center, prospective study based on N = 40 inpatients with COVID-19 in a general ward of a tertiary referral center in Switzerland. First, the Bayesian survival analysis shows that physiological measurements from consumer-grade wearables are significantly associated with the patient outcomes (i.e., discharge or intensive care unit admission). Second, our risk score achieves a time-dependent area under the receiver operating characteristic curve of 0.73 to 0.90 based on leave-one-subject-out cross-validation.
Our results demonstrate the effectiveness of consumer-grade wearables for risk scoring in COVID-19 inpatients. Due to their low cost and ease of use, consumer-grade wearables could enable a scalable monitoring system.
The study Wearable-based COVID-19 Markers for Prediction of Clinical Trajectories (WAVE) is registered at https://clinicaltrials.gov (Identifier: NCT04357834). The study followed the Declaration of Helsinki, the guidelines of good clinical practice, the Swiss health laws, and the ordinance on clinical research. The study was approved by the local ethics committee Bern, Switzerland (ID 2020-00874). Each patient gave informed written consent before any study-related procedure.
Due to specific characteristics of analytical information systems, their development varies significantly from transaction-oriented systems. Specific method support is particularly needed for ...requirements engineering and its information-related component, information requirements analysis. The paper at hand first evaluates the state of the art and identifies necessary method support extensions. On this basis, method support requirements for information requirements engineering are identified. The survey is structured along the five core activities of traditional requirements engineering. It reveals a need for further research especially on information requirements elicitation, validation, and management. It further contributes to a discussion of aspects that should be considered by any method support. Due to comparatively long life cycles of analytical information systems, the introduction of a process perspective is discussed in order to ensure the continuous elicitation, documentation, and management of information requirements.
One important means to explore the strengths and weaknesses of Business Intelligence (BI) initiatives is a comprehensive and accurate BI maturity assessment instrument. It is important that the ...assessment instrument is transparently developed using the current BI knowledge base. This paper proposes a BI maturity model that is based on an explicit BI maturity concept and using empirical data. The data is transformed into maturity levels by applying the Rasch algorithm and cluster analysis. The resulting BI maturity model is constructed on the basis of 58 items (capabilities). It is comprised of five levels that we choose to label "initiate","harmonize", "integrate", "optimize" and"perpetuate". An evaluation of the model demonstrates its utility.
Corporate management in today’s international companies has become increasingly complex. To cope with the growing challenges, information technology (IT)-based management control systems (MCSs) ...covering reporting, planning, and consolidation have been deployed. Despite their tradition in management research, the ‘right’ setup of MCSs is still challenging. Maturity models (MMs) are an established instrument to identify strengths and weaknesses of certain domains. As existing MMs rather focus on single MCS domains, neglect an IT perspective and miss a sound methodical foundation, this paper outlines an empirically and algorithmically constructed MCS MM. The model consists of three partial MMs for reporting, planning, and consolidation, which are integrated into one holistic MCS MM. The five levels of the MCS MM guide MCS evolution from a basic, mandatory/external-driven MCS (level 1) to a balanced MCS (level 2), and a comprehensive MCS (level 3). Ultimately, MCSs show a strong strategic focus (level 4) and leverage the potentials of modern IT (level 5).
