Descriptive Information
Brief Title  ICMJE Enhancing Use of Hydroxyurea In Sickle Cell Disease Using Patient Navigators
Official Title  ICMJE Enhancing Use of Hydroxyurea In Sickle Cell Disease Using Patient Navigators
Brief Summary

Multi-phase, patient navigator-based program in the Richmond and Tidewater regions of Virginia to demonstrate:

  1. the feasibility of using patient navigators to improve the percentage of children and adult (age 15 and older) patients with sickle cell disease (SCD) in SCD specialty care
  2. the efficacy of using patient navigators to improve hydroxyurea (HU) (re-)initiation and adherence among adult patients with SCD eligible for HU

(Patient navigators may also be known as public health workers.)

Detailed Description

The state of Virginia, including the Virginia Department of Health and three academic medical centers and one federally qualified health center, plans a two-phase demonstration, first of improvement in the percentage of adults with SCD who are in SCD specialty care (Phase I), then of improvement in adherence to HU of eligible SCD adults (Phase II). Both phases will use existing academic SCD providers, and an innovative, multimodal strategy, featuring specially trained SCD patient navigators (PNs), that addresses barriers to care and to HU use. In Phase I we will demonstrate the feasibility of utilizing PNs to overcome patient access barriers to SCD care. In Phase II we will test the efficacy of PNs for overcoming barriers to acceptance of and adherence with HU therapy. Patients will be randomized to a PN arm or to a usual care arm. Providers will implement NIH guidelines for HU eligibility and prescribing in both arms. All HU eligible patients will be offered HU at each clinical visit. Among patients prescribed HU, if a maximum tolerated dose (MTD, defined in end points) has not been reached, providers will dose escalate every 8-12 weeks to MTD, rather than to clinical effect, before declaring treatment success or failure.

This project will be critically important and impactful by demonstrating the feasibility of a statewide community-based strategy to assist vulnerable SCD adults in obtaining SCD specialty care and likely prolonging life, a model that other states could adopt.

Intervention Model: Parallel Assignment
Masking: Single (Investigator)

Condition  ICMJE Sickle Cell Disease
Intervention  ICMJE
  • Behavioral: Patient Navigator
    A specially trained (SCD knowledgable) Patient Navigator will act as a liaison who assists participants in increasing adherence to HU through disease education, addressing barriers to care and improving adherence to HU. PN utilize various techniques geared toward the individual patients needs. Interventions utilized by a PN include improving disease management skills, educational materials about disease, HU adherence, motivational interviewing, care coordination and social support.

Study Arms  ICMJE
  • Experimental: Phase I: Recruitment into Specialty Care
    Participants in the Phase I Experimental Arm are enrolled into SCD specialty care. PN's will contact patient up to 3 times to assure patients have had an initial visit by 3 months time.
    Intervention: Behavioral: Recruitment into Specialty Care
  • Experimental: Phase II: Patient Navigator Arm
    Participants in the Phase II Experimental Arm follow routine clinical care and are assigned a Patient Navigator. A specially trained (SCD specefic)PN will work with participants for one year. Participants will be contacted by their Navigator weekly for the first 6 months, then biweekly for the second 6 months.
