This session is intended for sharing and comparing computer software applications for research, management, and practice. Software applications will be demonstrated for decision analysis, cost effectiveness analysis, multi-attribute utility computation, and assessing patient utilities. Desktop applications will be discussed. Laptop and handheld computer software will be demonstrated. Pharmacoeconomic software allows data to be analyzed from different perspectives: patient, provider, hospital, managed care, and society. Software models also allow assessment of health care products or services from different quantitative perspectives: cost of illness, cost minimization, cost-benefit, cost-effectiveness, and cost-utility. The integration of decision analysis and spreadsheets will also be discussed. Software is utilized to collect information, analyze data, present findings, or educate managers, providers and patients. Pros and cons of each analytical and software approach will be discussed. Participants are encouraged to bring their own laptops to demonstrate their own software or related Internet offerings in an informal roundtable fashion. Software beta versions allowed; “viruses” discouraged.
