Trial Summary

What is the purpose of this trial?The goal of this clinical trial is to test two implementation strategies (automated health system \[Penn Medicine\]-mediated strategy vs. Family Heart Foundation-mediated strategy using a patient navigator) versus usual care to promote family cascade screening for familial hypercholesterolemia (FH) in Penn Medicine patients diagnosed with FH ("probands"). The main questions this study aims to answer are: (1) evaluating the effect of the three approaches on reach (proportion of probands who have at least one family member who completes screening), number of family members screened, number of family members diagnosed with FH, and proband LDL-C levels; and (2) identifying implementation strategy mechanisms focusing on health equity using mixed methods and oversampling populations that experience disparities. Participants (probands) in the active arms (health system \[Penn Medicine\]-mediated, Family Heart Foundation-mediated) will receive messaging that provides education about FH and provides instructions for participating in family cascade screening. A subset of probands will be invited to complete a qualitative interview about their experience receiving the implementation strategy. The research team will compare the active arms to Penn Medicine usual care for cascade screening to evaluate whether the active arms are more effective at promoting cascade screening than usual care.

Eligibility Criteria

This trial is for adults over 18 with familial hypercholesterolemia (FH) treated at Penn Medicine. They must have a cell phone or email and contact info for at least one living first-degree relative. It's not for those under 18 without these communication tools or family contacts.

Exclusion Criteria

I am under 18 years old.

Participant Groups

The study tests two strategies to encourage family screening for FH against usual care: an automated health system approach and a patient navigator-led strategy by the Family Heart Foundation. It measures how many relatives get screened, diagnosed, and effects on proband LDL-C levels.
3Treatment groups
Experimental Treatment
Active Control
Group I: Penn Medicine (health system)-mediatedExperimental Treatment1 Intervention
Probands receive automated text messages and/or emails through the Way to Health (WTH) platform containing information about FH and cascade screening from Penn Medicine, and a request to identify first-degree biological relatives. Probands choose whether to contact relatives themselves or share contact information so that automated text messages and/or emails can be sent by Penn Medicine to relatives directly via WTH. If probands opt to contact relatives themselves (self-contact), they receive tips on how to do this effectively. If probands opt for Penn Medicine to contact their relatives (direct contact), relatives receive information via WTH about FH and instructions for screening. All relatives (regardless of whether they were contacted via self-contact and direct contact) will be offered FH screening at no cost. If a proband's initial choice of outreach is not successful, they will have the option of initiating the alternate outreach approach (direct or self-contact).
Group II: Family Heart Foundation-mediatedExperimental Treatment1 Intervention
After using WTH to conduct an identity screen and giving probands an option to opt-out of having their information shared with Family Heart Foundation (FHF), FHF reaches out directly to probands via an FHF-employed navigator. During an initial call, the navigator introduces the proband to navigation services, conducts a social history, and initiates a plan for contacting relatives. Probands choose whether to contact relatives themselves (self-contact) or have FHF contact relatives directly (direct contact). Those who choose self-contact receive personalized coaching to address barriers and concerns. For direct contact relatives, FHF will call these relatives directly. All relatives (regardless of whether they were contacted via self-contact and direct contact) will be offered FH screening at no cost. If a proband's initial choice of outreach is not successful, they will have the option of initiating the alternate outreach approach (direct or self-contact).
Group III: Usual CareActive Control1 Intervention
Probands randomized to this arm will not receive any contact from the research team or Family Heart Foundation regarding cascade screening (i.e., no intervention).
