Comparison of Bacterial Contamination Rates Between Isolation and Non-isolation Rooms

Study Overview
=================
Brief Summary
-----------------
This study is to determine if medication cabinets located outside of isolation rooms in hospitals and their contents, particularly medications and the delivery folders are at a higher risk of having harmful bacteria on them.

Detailed Description
-----------------
Studies show high touch areas maybe contaminated with organisms such as Methicillin-resistant Staphylococcus aureus(MRSA) and vancomycin-resistant enterococci. MRSA can live on hospital surfaces for 9-14 days. Patients in rooms that were previously MRSA isolation rooms are at higher risk for developing a hospital-acquired infection. This study is to determine if medication cabinets located outside of MRSA isolation rooms and their contents, particularly medications and the pharmacy delivery folders are at a higher risk of having MRSA colonization on them. This study will use conventional methods to determine if MRSA colonization is present and compare results between non-isolation and isolation rooms. This will evaluate if alternate measures for the reduction of MRSA colonization are needed for the MRSA isolation rooms in regards to medication delivery and storage.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Isolation Rooms for MRSA<br>Rooms that currently have a patient in them that are in isolation status due to MRSA | |
| Non-isolation rooms<br>Rooms that have not been occupied by a patient in isolation due to MRSA for 14 days | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Presence of MRSA colonization | Swabbing of four areas of the medication cabinet will be performed (keypad, handle, medication folder and a medication). A Semi-quantitative sampling technique will be used to collect the samples. A sterile saline moistened sterile cotton tip swab will be used to swab the specified areas. The swabs will then be used to inoculate sheep blood agar plates in 4 quadrants. The plates will be incubated for 48 hours. The number of quadrants with growth will be identified. Individual colonies will be removed from the plate with an inoculation loop, then streaked onto a second sheep blood agar plate. The second plates will be incubated for 48 hours. The colonies will then be run through standard identification tests to determine if the colonies are MRSA or not. A comparison will be made between non-isolation and isolation rooms. | Hospital stay, an expected average of 14 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quantification of MRSA colonization | Swabbing of four areas of the medication cabinet will be performed (keypad, handle, medication folder and a medication). A Semi-quantitative sampling technique will be used to collect the samples. A sterile saline moistened sterile cotton tip swab will be used to swab the specified areas. The swabs will then be used to inoculate sheep blood agar plates in 4 quadrants. The plates will be incubated for 48 hours. The number of quadrants with growth will be identified. A comparison between the sites of swabbing will be performed. | Hospital stay, an expected average of 14 days |
