Brief Summary:
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.
Detailed Description:
This project leverages Penn Medicine's and the investigative team's longstanding partnership with the Family Heart Foundation (FHF), a nonprofit research and advocacy organization, to test two promising approaches to implementing cascade screening. The study will test two patient-facing implementation strategies to increase reach of cascade screening with FH probands within Penn Medicine. This pragmatic randomized controlled trial (RCT) will test (a) a health system (Penn Medicine)-mediated strategy using automated text messages and emails, (b) an FHF-mediated strategy delivered by a navigator, and (c) the "usual care" approach. Both active strategies use centralized direct contact to relatives and behavioral economics. Specifically, we will conduct a 3-arm hybrid type III effectiveness-implementation RCT.
Aim 1: Compare the effect of the three arms on effectiveness and implementation outcomes.
* Reach (primary outcome): proportion of probands who have at least one family member who completes screening
* Absolute number of family members screened
* Absolute number of family members with a new FH diagnosis
* Proband LDL-C levels 12 months post-randomization
Aim 2: Use mixed methods to identify implementation strategy mechanisms with a focus on health equity. In Aim 2a, the researchers will conduct qualitative interviews to understand proband perspectives on mechanisms of the implementation strategies using the Consolidated Framework for Implementation Research, oversampling for populations at risk for disparities. In Aim 2b, the researchers will explore disparities quantitatively by evaluating differential strategy effectiveness by race/ethnicity and gender; and descriptively explore differential strategy effectiveness by income and medical mistrust.
