To illustrate the use of decision-analytic modeling to assist decision making in organizational innovations.
STUDY SETTING/DATA SOURCES: Regarding an organizational innovation (shared care in hearing aid provision) available evidence from different sources was synthesized.
A probabilistic Markov model was constructed.
DATA COLLECTION/EXTRACTION: We modeled the long-term cost-effectiveness of different organizational formats of shared care as opposed to the current organization. We assessed the expected value of perfect information (EVPI) for several groups of parameters in the model.
The current organization had the highest probability of being cost-effective. Additional research is worthwhile, especially on access to care and safety (sensitivity to detect pathology).
Decision-analytic modeling in an early stage of organizational innovation is a valuable tool to facilitate evidence-based decision making.
说明决策分析模型在组织创新决策中的应用。
研究环境/数据来源：综合了不同来源关于组织创新（助听器提供的共享护理）的可用证据。
构建了概率马尔可夫模型。
数据收集/提取：我们对共享护理的不同组织形式与当前组织相比的长期成本效益进行建模。我们评估了模型中几组参数的完全信息预期价值 (EVPI)。
当前组织具有最高的成本效益概率。特别是在获得护理和安全性方面（检测病理的敏感性），进一步的研究是值得的。
在组织创新的早期阶段进行决策分析建模是促进循证决策的有价值工具。
