  1. *Mean score for all PPC-RD scales is on a 0–100 ± SD, so the scores above represent the percent of maximum obtainable systems in each category or scale.
  2. **These sub-scales don’t contain any items that do not address depression.
  3. All PPC-RD changes at year 1 are positive and statistically significant at P = <0.0001, except CCM decision support = 0.004.
  4. Priority to improve depression (self-rated on a 1 to 10 scale) increased at year 1 at P = 0.01.
  5. None of the values at 2 years post-implementation are different from those at year 1.
