NCT06155747

Brief Summary

The goal of this observational study is to facilitate standardized nontuberculous mycobacteria (NTM) outbreak investigations in healthcare centers. The main questions it aims to answer are:

  • Are respiratory NTM isolates identified as having membership in a suspected healthcare outbreak highly related based on whole genome sequencing?
  • Does epidemiologic investigation support healthcare-associated patient-to-patient NTM transmission?
  • Does healthcare environmental sampling support healthcare-associated NTM acquisition? If healthcare-associated NTM outbreaks are suspected, participants identified as having membership in a cluster of highly-related NTM infections will complete a demographic questionnaire.

Outcome Measures

Primary Outcomes (3)

  • Epidemiologic Investigation

    Identification of a shared healthcare-associated source(s) between patients in a healthcare center.

    5 years

  • Dust and Water Biofilm Collection

    Identification of healthcare dust and water biofilm NTM isolates that are highly related to the isolates recovered from subjects within a healthcare system.

    5 years

  • Home of Residence Watershed Mapping

    The primary endpoint is identification of common watersheds among subjects infected with clustered NTM isolates.

    5 years

Secondary Outcomes (2)

  • Epidemiologic Investigation

    5 years

  • Healthcare Environment Dust and Water Biofilm Collection

    5 years

Study Arms (1)

People infected with related NTM isolates identified as having membership in a related cluster

Characterize the source(s) of acquisition and/or direct or indirect patient-to-patient transmission of NTM within a healthcare setting among participants with highly related isolates.

Other: Epidemiologic investigation

Interventions

Identification of: 1. overlaps in source(s) of care between participants with NTM isolates in a healthcare center. 2. environmental NTM isolates that are highly related to respiratory isolates. 3. common water source exposure among subjects with clustered NTM infections via shared home of residence watershed.

People infected with related NTM isolates identified as having membership in a related cluster
