to pressure ulcers. We used TreeAge Pro 2009 Suite (TreeAge Software, Williamstown, MA)
to construct the Markov model, including a total of 21 mutually exclusive health states.

We obtained input estimates from current systematic reviews of pressure ulcer prevention,4,18 the Tri-Hospital Pressure Ulcer Prevalence Survey (Supplemental Appendix), the Ontario Case Costing Initiative,33 a large data set for home care in Ontario,34 and additional literature searches.
