Cost-Effectiveness Analysis
模型构建完成后,TreeAge Pro自动生成所需的评估模型和选择优策略所需的算法。这使您能够专注于手头上的问题,而不是评估模型所需的计算。标准算法根据策略的概率对每个可能的结果赋予权重。合并加权平均产生每个策略的总体期望值。
TreeAge Pro的 Healthcare Module允许您在成本效益基础上通过增量成本效益和/或净效益比较战略。您也可以根据成本或比较效益(CER)来比较同一模型中的策略。您甚至可以使用非标准的测量,如感染、等。
下面的模型比较了的两种方法。
Simple Healthcare Tree
成本效益分析比较基于CE边界的策略。
Cost-Effectiveness Graph
如果在这个模型中有占主导地位的策略,它们将在上面和左边的CE边界上出现。排名报告显示了比较策略的数值计算,包括增量成本效益比(ICER)。
Cost-Effectiveness Rankings
ICER跟支付意愿(WTP)比较临界值,以确定我们是否能够在成本效益基础上提供更有效的方法。
Single-User Licenses
All licenses are single-user licenses. Every person requires his/her own license to access TreeAge Pro software. The following would be considered out of compliance, and illegal access of TreeAge Software: Placing the software on any device that is (or can be) shared with other people (shared PC’s / laptops for example) or transferring a single user licenses to any other individual (unless it is a permanent transfer). Installing a single user license on a server is also illegal.
Single-user licenses must be registered under the name of the sole individual who will use the license. Any use by individuals other than the registered user is prohibited, including sharing the same computer and any temporary transfer or use.
TreeAge Pro can only be installed and authorized on the standalone computer of the registered user. Installation on other computers, servers, shared machines or virtual machines is strictly prohibited. Single user licenses cannot be installed in classrooms, labs or library settings.
Shared usage will result in a nonrefundable forfeiture of the license plus fees equal to the cost of a network license based on your organization type. Depending on the severity of the violation, and / or length of violation, further legal action will be taken.
TreeAge Pro is the leading tool for building decision trees, Markov models and event-based simulations
Study Uncertainty on Healthcare Models
TreeAge Pro允许您去研究模型输入中的不确定性如何影响结果,而这个结果我们可以通过输出来绘制。TreeAge Pro提供两种方法研究不确定性:
确定性的敏感性分析
概率敏感性分析
Healthcare Module扩展两类敏感性分析,通过成本-效果分析比较策略。确定性的敏感性分析在取值范围内研究不确定性个体参数。确定性敏感性分析常见的形式是通过1-way 敏感分析来研究单一参数。还支持2-way,3-way和龙卷风图。
为了在模型中运行1-way敏感性分析,参数必须用变量表示。然后,变量可以不确定的范围内进行分析,而不是使用一个单点估计。
看看下面的模型。
Simple Healthcare Tree
也许我们担心的是用手术和放射来根除的可能性。我们在pEradicateRadSurg变量值范围为0.5到0.9之间有4次间隔的运行1-way敏感性分析。这将重新计算模型值5次,变量值分别为0.5,0.6,0.7,0.8和0.9。
