What are the Major Clinical Pathways to Disability

This is the question posed by a 2007 NBER working paper by Mary Beth Landrum, Kate A. Stewart, David M. Cutler. The authors use data from the National Long Term Care Survey (NLTCS) between 1994 and 1999. The data is panel in nature and has the benefit of combining Medicare administrative data with survey responses. The research examines individuals over 65 without disabilities in 1994 and see which patients became disabled and how this occurred.
