Microorganisms that colonize hospital environments play an important role in the transmission
of hospital acquired infections (HAI) and multi-drug resistant organisms. Previous studies
examining microorganisms in the hospital environment have been limited by reliance on
targeted culture-based methods resulting in potentially missed or unrecognized organisms.
Evidence now suggests that using microbiome analysis offers an innovative strategy that may
improve our understanding of HAI and how best to prevent them.
This pilot longitudinal observational study aims to characterize the taxonomic composition of
microbial communities on environmental surfaces and people in these environments prior to and
following the introduction of patients, caregiver, and hospital staff to newly constructed
inpatient care areas at St. Jude Children's Research Hospital (SJCRH). This proposed study is
uniquely characterized by evaluating the hospital environment of a pediatric
immunocompromised oncology patient population that has not been studied in the past using
advanced molecular techniques such as microbiome analysis.
PRIMARY OBJECTIVE:
- To describe the pattern of microbial communities of the hospital environment before,
during and after patient occupancy of a newly constructed hospital space.
SECONDARY OBJECTIVES:
- To describe the similarity or difference of environment microbial communities to that of
the humans occupying this environment in a newly occupied hospital space.
- To describe the pattern in environment microbial communities after each step of
disinfection (manual cleaning with chemical disinfectant and Ultraviolet light
disinfection machine) after patient discharge from the inpatient hospital environment.
- To evaluate the correlation between environmental Adenosine Triphosphate (ATP) measures
and organism bioburden.

Primary | Change in diversity index of environment microbial composition | Microbial flora colonizing a newly built hospital environment will be compared prior to participant inpatient admission to after inpatient hospital discharge. Microbiome diversity is a measure of the richness of microbial species present in the environmental sample. It is reported as diversity index. | Before participant admission to after participant discharge, which is up to 30 days | |
Primary | Change in microbiome composition within the environment microbial composition | Microbial flora colonizing a newly built hospital environment will be compared prior to participant inpatient admission to after inpatient hospital discharge. Microbiome composition describes which bacteria are detected in a sample. It is reported as percentage of relative abundance of each taxa of bacteria. | Before participant admission to after participant discharge, which is up to 30 days |
