Reducing Staphylococcus aureus infections in Indigenous communities

SHIELD (Staph Intervention for Effective Local Defense): An Open-label Randomized Controlled Trial to Assess Efficacy of a Sustained Intervention (Topical Antibiotics and Skin Antisepsis) to Decrease Staphylococcus Aureus Carriage in Adults

Phase 4 Interventional Johns Hopkins Bloomberg School of Public Health · NCT06210594

This study is testing a new way to help Native American adults living near the White Mountain Apache Tribal lands reduce the presence of Staphylococcus aureus infections by providing education and supplies, along with some receiving a special treatment.

What this trial studies

This clinical trial aims to evaluate a community-informed approach to reduce the carriage of Staphylococcus aureus (SA) among Native American adults living on or near the White Mountain Apache Tribal lands. Participants will receive education and household supplies for prevention, with some also receiving a biomedical intervention involving mupirocin, Nozin, and chlorhexidine gluconate. The study will compare the effectiveness of these interventions in reducing SA carriage, which is a significant factor in the development of infections. The trial addresses the high burden of SA and MRSA infections in this population, aiming to improve health outcomes through targeted interventions.

Who should consider this trial

Good fit: Ideal candidates are Native American adults aged 18 and older who have lab-confirmed SA carriage and risk factors for SA-associated infections.

Not a fit: Patients without a permanent home or those currently infected with Staphylococcus aureus may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of Staphylococcus aureus infections in Indigenous communities.

How similar studies have performed: While there have been various approaches to decolonization, this community-informed strategy is novel and specifically tailored to the needs of the White Mountain Apache community.
