The CKD registry provided primary care practice teams with point-of-care data about patient-specific CKD status, recent ambulatory clinic blood pressure (BP) readings, status of Angiotensin Converting Enzyme inhibitor (ACEi) or Angiotensin Receptor Blocker (ARB) prescription, and quantification of albuminuria (UACR). It also provided data about diabetes care, immunization status, and data pertinent to age appropriate cancer screening, to align with usual care. Point-of-care decision support reminded primary care providers (PCPs) about guideline concordant care for individuals with CKD. Quarterly feedback to practice teams and individual PCPs identified patients with CKD and BP >140/90 mmHg, those not prescribed an ACEi/ARB, and those with albuminuria.

Usual care consisted of an electronic registry that was in use before trial implementation. It provided practice teams with point-of-care data about diabetes care, age-appropriate cancer screening and immunizations, but no CKD-related data. Medical assistants were encouraged to use the usual care registry to identify patients who were due for cancer screening or immunizations. Quarterly feedback was not provided for practice teams randomized to receive usual care.
