Conclusions
The conclusion from the original randomized clinical trial of the Camden Core Model that the intervention did not work may have been premature, because the estimated treatment effect in the ITT analysis was averaged over a population including patients who received low-intensity and short-term intervention. In this reanalysis of the Health Care Hotspotting trial, the distillation method helped identify individuals for whom intervention delivery was successful and whether the intervention worked when it could be delivered more fully. Both questions are essential to producing policy relevant results in evaluations of care management programs.
