Evaluation of an Electronic CKD Clinical Decision Support System (CDSS) in Clinical Care

Study Summary

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.

Primary Outcome

Clinical Outcome: The primary clinical outcome of the trial is change in blood pressure (mmHg) from enrollment to the end of the follow up period as a continuous outcome, ascertained from the electronic medical record. BP measures from the clinical record will be ascertained in no more than quarterly intervals in the primary care setting to avoid bias by ascertainment. Investigators will also consider the dichotomous clinical outcome "achieved sustained BP control", defined as BP \< 140/90 mmHg
