The purpose of this paper is to introduce a decision support system to prioritize needs that are anchored in an organization. We build on a systems-thinking approach and develop a weighted additive index which considers different viewpoints of organizational stakeholders. First, we briefly review the literature about identifying and prioritizing needs from various scientific disciplines. Then, we use boundary critique to identify critical stakeholders that lead to three different viewpoints in the decision support system. The internal view reflects needs that members of the organization find important and urgent to be satisfied. The external view considers knowledge of outsiders, i.e. who do not work in the organization but are acquainted with it (e.g. experts, customers, facilitators). The systemic view considers system inherent interrelations of needs as perceived by decision makers in the organization. These stakeholder views get assessed by different dimensions, which are subsequently combined and weighted. Based on a method to identify needs, we apply this index in an case study conducted in Austria and discuss implications for theory and practice.

Aim: To examine the adoption of CCDS by paramedics, including the impact of CCDS on paramedic role and practice. Methods: Systematic review of CCDS in emergency care followed by a cluster-randomised controlled trial (C-RCT) of CCDS with a qualitative component involving 42 paramedics at two study sites. Results: 19/20 studies identified for inclusion in the systematic review were from the Emergency Department setting, with no studies from prehospital care. The focus of the studies was on process of care (19/20) rather than patient outcomes (5/20). Positive impacts were reported in 15/19 (79%) process of care studies. Only two patient outcome studies were able to report findings (one positive, one negative). Results relating to CCDS implementation were reported as an ad hoc response to problems encountered. In this C-RCT paramedics used CCDS with 12% of eligible patients (site one: 2%; site two: 24%). Intervention paramedics were twice as likely to refer patients to a falls service as those in the control group (usual care) (relative risk = 2.0; 95% Cl 1.1 to 3.7) although conveyance rates were unaltered (relative risk = 1.1; 95% Cl 0.8 to 1.5) and episode of care was unchanged (-5.7 minutes; 95% Cl -38.5 to 27.2). When CCDS was used patient referral to falls services was three times as likely (relative risk = 3.1; 95% Cl 1.4 to 6.9), and non-conveyance was twice as likely (risk = 2.1; 95% Cl 1.1 to 3.9) and overall episode of care fell by 114 minutes (95% Cl from 77.2 to 150.3). Reasons given for not using CCDS included technical problems, lack of integration, it was not sophisticated enough to influence decision making. Paramedics adapted when and how they used CCDS to suit context and patient condition. Conclusion: There is little existing evidence in relation to CCDS use in the emergency care setting, and the prehospital emergency care setting in particular. Studies of CCDS undertaken in emergency departments have shown benefit, particularly in relation to process of care. The C-RCT found that CCDS use by paramedics was low, particularly at site one, but use was associated with higher rates of patient referral and non-conveyance, and shorter episodes of care. There were encouraging signs that CCDS can support a new decision making role for paramedics. The study provides useful lessons for policy makers, practitioners and researchers about the potential benefits of CCDS and the challenges to adoption of new technology in emergency prehospital care.

M.Com. (Business Management) / The ultimate objective of this research report was to develop a Decision Support System, (DSS), that can be used by property professionals to enable them to make better decisions regarding property development in South Africa. The DSS addresses the problem of numerous uncertain variables in property development investment decisions. The capability of the computer to do repetitive calculations with different combinations of variables, with probabilities linked to each variable, was used in a Monte Carlo analysis. The DSS was developed on a "Lotus 1-2-3™ Release 4 for Windows" spreadsheet which makes the program adaptable to suit specific applications if the need arises. The DSSwill, however, be able to address the majority of property developments without any adaptation. The DSS was appraised by property professionals and the comments received from the respondents indicate that the primary objective stated was achieved. The DSS is best suited for property investors who are also involved in the early development phases.
