Brief 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.

Arm Intervention/treatment
Experimental: Clinical Decision Support System (CDSS)

PCPs get a notice the CKD Clinical Decision Support System (CDSS) is available.

CDSS overview:

  • The study MDs order CKD triple marker tests
  • Patients will go to the lab as per usual clinical care
  • Lab results are returned to PCPs clinical results folder as per usual clinical workflow with information about CKD and link to KDIGO guidelines
  • Results will also be sent to the Study MD's for monitoring
  • At the patient's next visit, if the labs are completed, the full CDSS launches for the PCP
  • If the labs are not completed by the next visit, a Best Practice Alert (BPA) will launch for the PCP notifying them that the labs have been ordered, but the patient hasn't done them yet
Other: Clinical Decision Support System (CDSS)
A targeted, automated CKD clinical decision support system (CDSS) designed to improve bloodpressure (BP) level, disease awareness, staging, processes of care, and knowledge among persons with documented reduced eGFRcreat (creatinine-based estimated glomerular filtration rate) in primary care setting.

Experimental: Clinic Decision Sup System + Pharmacist

The Clinical Decision Support System + Pharmacist follow-up call extends beyond the CDSS alone.

CDSS Plus overview:

  • At the visit in which the CDSS launches, the PCP will hand a study card with pharmacist information to their patient notifying them that a pharmacist will be calling to follow-up after the visit
  • The pharmacist will use MyChart and/or phone calls to schedule a follow-up call within two weeks of the visit
  • On the follow-up phone call, the pharmacist will discuss understanding of CKD, medication review and adherence assessment, home BP checks, and the importance of NSAID avoidance
  • A second follow-up call will only be scheduled if the patient is non-adherent with their medications and makes an active plan for adherence with the pharmacist, or if the patient requests an additional call from the pharmacist
Other: Clinic Decision Sup System + Pharmacist
Includes everything in the CDSS intervention but adds a follow-up call from a pharmacist, who is part of the clinical team. The rationale for this third arm is based on the evidence that clinical pharmacists have been shown to be more effective than physicians alone at achieving BP control in other settings.
Other Name: CDSS Plus, Clinical Decision Support System + Pharmacist

No Intervention: Usual Care
Patients continue to receive usual care by their provider.

Primary Outcome Measures :
  1. Change in blood pressure from enrollment [ Time Frame: Investigators will follow patients up to 2 years after measures ]
    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 in ≥ two consecutive visits during the trial.

Secondary Outcome Measures :
  1. Feasibility [ Time Frame: Investigators will follow patients up to 2 years after measures ]
    Investigators will assess provider awareness of CKD, defined as percent appropriate inclusion of CKD in the problem list (dichotomous outcome).

  2. Processes of Care [ Time Frame: Investigators will follow patients up to 2 years after measures ]
    Investigators will also measure use of ACEI/ARB among persons with albuminuria, measured as the proportion (percent) of persons on these medications at the end of the study period, compared to enrollment. Medication prescription will be ascertained by percent with an electronic record of a new order or modification during the study period, not including refills. Other process outcomes relate to feasibility and the ability to implement the CDSS protocol. These include proportion in the intervention arms with completion of albuminuria and cystatin C testing.

  3. CKD and NSAID avoidance Knowledge [ Time Frame: Investigators will interview each participant 2 weeks after their primary care visit or clinical pharmacist phone call ]
    Patient-centered outcomes: Investigators will evaluate CKD and NSAID avoidance knowledge (proportion with correct answers), using structured telephone interviews, and comparing patients from the three study arms.

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: No
Plan Description: Plan for monitoring data and safety: A recommendation to order a creatinine and potassium level following initiation or up-titration of ace/arb will be incorporated in the algorithm in the result note. A 24/7 line to a nephrology answering service will be available to participating Primary Care Providers (PCPs) in the case of critical results; for non-critical study-related questions, participating PCPs can contact the study nephrologist via staff messaging in APeX. If a patient is found to have eGFR < 30 ml/min/1.73m2, investigators will recommend nephrology referral for pre-dialysis care.
