Calibration of Transition Intensities for a Multistate Model: Application to Long-Term Care
نویسندگان
چکیده
We consider a non-homogeneous continuous time Markov chain model for Long-Term Care with five states: the autonomous state, three dependent states of light, moderate and severe dependence levels death state. For general approach, we allow non null intensities all returns from higher to lesser dependencies in multi-state model. Using data 2015 Portuguese National Network Continuous database, as main research contribution this paper, propose method calibrate transition one step probabilities estimated data. This allows us use chains modeling Care. solve numerically Kolmogorov forward differential equations order obtain probabilities. assess quality calibration using life expectancies. Based on reasonable monthly costs each state compute, by Monte Carlo simulation, trajectories process derive relevant information validation premium calculation.

The Evolution of Long-term Care Programs; Comment on “Financing Long-term Care: Lessons From Japan”
The need for long-term care (LTC) represents a “new social risk,” one that overlaps with and complements systems of care that pre-date such programs, complicating LTC program design. This commentary expands on Ikegami’s discussion of how these structural factors must be accommodated, as well as historical and cultural factors that influence public expectations of such a...
متن کاملSpontaneous Mesenchymal to Epithelial Like Tissue Transition (MET) in a Long Term Human Skin Culture
In an attempt to isolate multipotent stem cells from foreskin in a long-term culture, we encountered an interesting phenomenon which was the conversion of the fibroblast dominant condition to epithelial-like tissue formation. However, the basic mechanism(s) which may be involved in this conversion is not clear. This study was designed to evaluate the cells protein secretion activity and examine...
