The investigators propose a three-arm, pragmatic, cluster-randomized clinical trial based in primary care. Participating Primary Care Providers (PCPs) will be randomized to usual care or one of two intervention arms. The first intervention will evaluate the efficacy of an automated CDSS that utilizes the electronic health record (EHR) to facilitate triple marker test ordering, guideline implementation and BP management, compared with usual care, among patients with previous documentation of eGFRcreat <60 ml/min/1.73m2. The second intervention goes a step further, and will evaluate whether a CDSS plus a follow-up telephone call from a pharmacist (CDSS PLUS) can improve BP management and patient CKD and NSAID toxicity knowledge among the patients with CKD, compared with CDSS alone. The primary clinical outcome is BP level, with secondary outcomes related to processes of care and patient knowledge.
