Case Studies

In today’s sound-bite culture there are difficulties with reducing wondrously complex, fascinating stories down to a few words or pictures. We do, however, summarize in our single page client client reports, backed up with a feel for the complexities.

Rather than giving cherry-picked case studies, we always publish our most recent case. No matter what the results, all are archived and available for review. We liken what we do to heart surgery, procedures are almost invariably successful once a case is accepted. There are varying degrees of success and a portfolio of projects preserves the most accurate statement of overall findings.

HEALTHCARE | Health at Home, not Hospital
In the past couple of decades, Care and Disease Management (CM/DM) has grown sharply, responding to greater need for healthier living. The clinical models are various, often including telephonic nursing care. Measurements include hospitalizations averaging $10,000 each; re-admits; ER visits; adherence to medications; quality of life; etc. Simultaneous statistical design offers a solution since thousands of people in a population are given care by separate teams of care providers. Mathematically, this problem-type is similar to multi-channel retail sales optimization. Continue Reading >>>
