In the United States, the burden of chronic kidney disease (CKD) rests disproportionately on rural communities. This study evaluates the implementation and effectiveness of CommunityRx-Kidney Health (CRx-K); this health information technology intervention integrates medical, social, and self-care resources to improve CKD management in rural eastern North Carolina. Through a partnership among local primary care centers, community organizations, and researchers, CRx-K will strengthen rural care networks, improve CKD management, and enhance the well-being of rural communities.
Approximately one in seven adults in the United States lives with chronic kidney disease (CKD). CKD typically worsens with time and, in its final stage, can result in kidney failure. Contextual factors in rural, eastern North Carolina communities impede optimal management of CKD multimorbidity. In these communities, geographical barriers to medical care, dwindling resources, and underdeveloped health infrastructure have worsened CKD outcomes. CommunityRx-Kidney Health (CRx-K) is an evidence-based, low-intensity, health information technology-driven intervention designed to support CKD management in rural eastern North Carolina. CRx-K integrates medical (e.g., blood pressure and glucose monitoring, eye and foot care), social (food, housing, transportation), and self-care (weight and stress management, exercise) resources. CRx-K comprises three components: brief education on integrated CKD needs, a personalized community resource referral list (HealtheRx), and clinic navigator-led, longitudinal support (12 months) for CKD patients in our trial. Our multidisciplinary, community-engaged research team will test the effects of CRx-K through three related aims.
This pragmatic individual-randomized, two-arm, single-blind trial in 35 rural primary care clinics in 16 rural eastern North Carolina counties (n=634 adults with CKD) assesses the effect of CRx-K on acute healthcare utilization (primary outcome), self-efficacy for finding resources, knowledge and sharing of integrated care resources, resource use, number of unmet needs over time, ambulatory care utilization, and health-related quality of life. The researchers hypothesize that 12-month acute healthcare utilization will differ between participants receiving CRx-K and those receiving usual care.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

CommunityRx-Kidney Health (CRx-K) is an evidence-based, low-intensity, health information technology-driven intervention designed to support chronic kidney disease management in rural eastern North Carolina. CRx-K integrates medical (e.g., blood pressure and glucose monitoring, eye and foot care), social (food, housing, transportation), and self-care (weight and stress management, exercise) resources. CRx-K comprises three components: brief education on integrated chronic kidney disease needs, a personalized community resource referral list (HealtheRx), and clinic navigator-led, longitudinal support (12 months) for chronic kidney disease patients.

Acute healthcare utilization
Acute healthcare utilization is measured as the sum of self-reported 911 calls, ambulance visits, emergency room visits, urgent care visits, and hospital admissions across the 12-month follow-up period.
Time frame: 12 months
Ambulatory healthcare utilization
Number of ambulatory (physician office) visits across the 12-month follow-up period is self-reported based on responses to an item originally used in DIAMOND RCT: "How many times have you seen a physician for an office visit?"
Time frame: 12 months
Self-efficacy for finding social and self-care resources
Self-efficacy for finding social and self-care resources is measured using an item developed from Bandura's self-efficacy theory and used in prior CommunityRx trials: "How confident are you in your ability to find resources in your community that help you manage your health?" Responses will be assessed on a 4-point Likert scale ranging from '1' (not at all confident) to '4' (completely confident).
Time frame: 6 months, 12 months
Attitudes about social and self-care resources
Attitude about social and self-care resources are measured using a self-report Likert item adapted and tested in prior CommunityRx studies: "Your community has the resources you need to manage your health." Response options range from '1' (strongly agree) to '5' (strongly disagree).
Time frame: 6 months, 12 months
Knowledge of social and self-care resources
Knowledge of social and self-care resources is measured using a self-reported item adapted and tested in prior CommunityRx studies and repeated for 12 resource types: "Do you know of places in your community that offer \[resource type\]?" The research team will report the sum of resource types that participants endorse knowledge of.
Time frame: 6 months, 12 months
Use of social and self-care resources
Use of social and self-care resources (for which a participant reports knowledge) is measured using a self-report item adapted and tested in prior CommunityRx studies and repeated for 12 resource types: "Have you received services from places like this for you or your household in the past 3 months?" The research team will report the total number of resource types that participants endorse using.
Time frame: 6 months, 12 months
Unmet social and self-care needs
Unmet social and self-care needs are measured using self-report items adapted and tested in prior CommunityRx studies and repeated for 12 resource types. Participants who report not having used a resource type in the past 3 months respond to: "Is this a service that you or your household needs?" Participants who report having used a resource type in the past 3 months respond to: "Do these places meet your \[resource type\] needs?" The research team will report the total number of resource types that participants endorse needing.
Time frame: 6 months, 12 months
Sharing of information about social and self-care resources
Sharing of social and self-care resources (for which a participant reports knowledge) is measured using a self-report item adapted and tested in prior CommunityRx studies and repeated for 12 resource types: "Did you tell anyone about places like this in the past 3 months?" The research team will report the sum of resource types that participants endorse sharing.
Time frame: 6 months, 12 months
Health-related quality of life
The 10-item Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 assesses general health-related quality of life and is self-reported. Response options are presented as nine 5-point and one 11-point Likert scales. Higher raw sum scores indicate greater health-related quality-of-life.
Time frame: 6 months, 12 months
