Latinos Using Cardio Health Actions to Reduce Risk (LUCHAR): Evaluation of a Navigator-Nurse Care Team on Hypertension and Cardiovascular Disease Risk

The purpose of this trial is to study the effect of a patient navigator-nurse team in improving the management of hypertension and other cardiovascular disease risk factors in a health care system taking care of a vulnerable, mostly Latino population.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study represents one phase of a large partnership grant with The Colorado Health Outcomes Program of the University of Colorado at Denver Health Sciences Center (UCDHSC) and Denver Health and Hospital Authority (DH). The overarching goal of Latinos Using Cardio Health Actions to Reduce Risk (LUCHAR) is to improve the primary and secondary prevention of cardiovascular disease (CVD) in Hispanics through a comprehensive research program aimed at (1) increasing awareness of CVD risk in the Hispanic community and increasing participation of high risk Hispanics in the health care system, (2) developing more effective models of care delivery for high risk patients in a health system, and (3) identifying markers that will more effectively identify Hispanic patients at high risk of CVD than current approaches based on traditional risk factors.

This trial has been designed to assess the effectiveness of a quality improvement project which focuses on the hypertensive multiracial underserved population within the Denver Health system. In addition, we are hoping at study end to have developed and validate this project as an efficient and sustainable approach to improving blood pressure control and controlling cardiovascular risk factors, especially in the vulnerable patient population served at Denver Health.

The objective of this quality improvement program is to conduct a randomized, primary care-based, efficacy trial evaluating the effectiveness of a patient navigator-nurse disease management intervention for treating hypertension and its associated cardiovascular risk factors using information obtained in earlier phases of the LUCHAR grant: i.e., algorithms, risk factor profiles, and qualitative data from focus groups and interviews. The study is designed to test the hypothesis that a patient navigator-nurse assisted intervention will improve blood pressure (BP) in vulnerable hypertensive patients, compared with usual clinical care.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 74 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Active patients from the Target Adult Health Clinic
  • Identified with a diagnosis of hypertension
  • Uncontrolled hypertension (2 of 3 last BP measurements above target BP range; target BP is defined at 140/90 or 130/80 mm Hg for people with diabetes or kidney disease)

Exclusion Criteria:

  • Pregnant or breastfeeding
  • End-stage kidney disease requiring dialysis
  • Co-morbid illness with life expectancy less than 12 months
  • Institutionalized individuals because of the potentially confounding factors due to severe co-morbidity or other medical conditions

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 1
Patient navigator-nurse disease management intervention
Behavioral: Patient Navigator - Nurse Team Intervention
The patient navigator-nurse disease management intervention for treating hypertension and its associated cardiovascular risk factors will use information obtained in earlier phases of the LUCHAR grant: i.e., algorithms, risk factor profiles, and qualitative data from focus groups and interviews. The study will test the effect of this intervention on blood pressure control and utilization of hospital services in adult patients with hypertension.
No Intervention: 2
Usual clinical care

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Change in SBP level
Time Frame: Measured at Year 1
Measured at Year 1

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Percentage of participants with BP control by JNC-7 guidelines, adherence with BP medications, lipid control, change of HgbA1c for participants with diabetes, and change in smoking status/BMI
Time Frame: Measured at Year 1
