1Neonatal Intensive Care Unit (Ms Kirkby) and Microbiology, (Ms Biggs), Penn Medicine Chester County Hospital, West Chester, Pennsylvania.
Summary
Cell phones in neonatal intensive care units (NICUs) harbor bacteria, posing infection risks to vulnerable infants. Regular disinfection significantly reduces microbial contamination, enhancing NICU hygiene and patient safety.
Area of Science:
- Microbiology
- Infection Control
- Neonatal Care
Background:
- Neonatal intensive care unit (NICU) infants have immature immune systems, increasing susceptibility to infections.
- Invasive procedures and prolonged stays in the NICU heighten infection risks for infants.
- Cell phones used by staff and visitors can introduce bacteria into the NICU environment.
Purpose of the Study:
- To evaluate and improve the cleanliness of cell phones used in the NICU.
- To assess the effectiveness of disinfectant wipes in reducing bacterial contamination on cell phones.
Main Methods:
- Bacterial samples were collected from 18 NICU parents' and staff's cell phones before and after disinfection.
- Phones were incubated for 2 days to assess microbial growth.
- Participants completed surveys on their cell phone cleaning habits.
Main Results:
- All tested cell phones showed microbial contamination prior to disinfection.
- Disinfection with surface disinfectant wipes substantially reduced bacterial contamination on all phones.
Conclusions:
- A standardized cleaning protocol using surface disinfectants effectively reduces germ transmission in the NICU.
- Cell phone hygiene is crucial for protecting high-risk infant populations.
- Further research is needed to establish hospital policies on device cleaning to prevent nosocomial infections.

12.8K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

6.4K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:26Physical Methods for Controlling Microbial Growth: Radiation and Filtration
1.5K
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.
