About this study
Official title: A New Combination of Evidence-Based Interventions to Improve Primary Care Diagnostic Safety and Efficiency: a Stepped Wedge Cluster Randomized Control Trial (RCT)
The purpose of this study is to measure the evidence-based intervention's (EBIs) impact on patient safety and efficiency, to assess the EBIs implementation by measuring acceptability, appropriateness, cost, fidelity, penetration, and sustainability and to identify the facilitators and barriers that influence the degree of implementation of these EBIs.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Enhanced diagnostic team implementing three evidence-based interventionsOther
we designed an enhanced team process entailing: 1) using automated abnormal test result detection and tracking; 2) expanding the primary care team to include CPs to guide the evaluation of anemia to identify underlying causes; and 3) using NNs to engage patients in the healthcare team and diagnostic process and increase patient activation.
Usual careOther
Also called Control
Usual care involves primary care physicians ordering additional tests and referrals to evaluate patients with new anemia and decreased glomerular filtration rate (GFR) .

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of subjects who have correct diagnosis of cause of low hemoglobin
Percentage of subjects who have correct diagnosis of cause of low hemoglobin
Measured: within 6 months from baseline
Percentage of subjects who have correct diagnosis of cause of low glomerular filtration
Percentage of subjects who have correct diagnosis of cause of low glomerular filtration
Measured: within 6 months from baseline
Secondary outcomes (11)
Time until diagnosis
Time until diagnosis is defined as number of days from the initial abnormal test result to the day the diagnosis was communicated to the patient.
Measured: initial abnormal test result to the day the diagnosis was communicated to the patient (about 1-6 months)
Percentage of tests appropriately utilized
Percentage of tests appropriately utilized will be calculated as the number of appropriate tests ordered to evaluate the abnormal test divided by the total number of tests ordered to evaluate the abnormal test, multiplied by 100.
Measured: within 6 months from baseline
Cost of treatment
Costs will be assessed from the health care system perspective and will include the costs of all diagnostic tests and referral consultations to evaluate the abnormal tests, emergency department (ED) visits or admissions for care for the underlying diseases causing test abnormalities, and the personnel time to provide the EBIs during the 6-month work up period.
Measured: from baseline to 6 months
Number of primary care physicians (PCPs) who find the intervention as acceptable assessed by survey of PCPs
Number of primary care physicians (PCPs) who find the intervention as acceptable
Measured: 12 weeks after PCP's patient enrolled

Measured: 6 months
Sustainability as assessed by number of clinics that continued the intervention
Measured: 2.5 years
Patient activation as assessed by the short form of the Patient Activation Measure (PAM)
This 13-item survey uses a 5-point Likert scale to measure 4 domains related to patient activation. Total score ranges from 1 to 65, with a higher score indicating greater activation.
Measured: between 1 to 6 months
Number of clinics with more facilitators than barriers
Number of clinics with more facilitators than barriers

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Percentage of subjects who have correct diagnosis of cause of low hemoglobin (time frame: within 6 months from baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05735314, which also lists 2 linked publications.
