The Case for Single-Use, Disposable EEG Cup Electrodes

Follow the research

The case for switching from reusable EEG cup electrodes to disposable EEG cup electrodes is based on multiple studies and the demand for Universal Precautions within the  workplace. “Use of single-use electrodes and research on scalp infection and infection reduction interventions are warranted.”1 In a multicenter study, 22.6 % of cleaned reusable EEG cup electrodes and lead wires were found to contain bacteria that were potential risk or at risk for infection, including MRSA and Chicken Pox.2

Semi-critical care and disinfection

EEG and EP electrodes and their lead wires are categorized as semi-critical patient care items because they may come into contact with mucous membranes (nose, mouth, eyes, etc.) or non-intact skin (as in skin that has been prepped using an abrasive to lower impedance).

Semi-critical items require high level disinfection, which warrants autoclave or 10 to 30 minutes of full liquid immersion in an EPA-approved high-level disinfectant chemical sterilant. “High-level disinfection of semi-critical patient care items cannot be achieved by a spray or wipe method.”3

Patients with healthcare associated infection (HCAI) cost 2.8 times more per case to treat, stay in hospital 2.5 times longer and are seven times more likely to die.4

Clinical and Financial Implications

Use of single-use EEG cup electrodes may be associated with overall hospital savings.5

The largest outbreak of Hepatitis B in a Healthcare setting was attributed to outpatient EEG labs

A chief technician with a high viral load and inadequate infection control practices in the six partner clinics were responsible for what is probably the largest documented outbreak of Hepatitis B in a health care setting.

14,000 cases of Hepatitis B were acquired from 1991 to 1996 at six EEG labs owned by the same physician and chief technician, with one death reported during those five years. Centers for Disease Control and Prevention report that HBV can live on an inanimate surface for one week.

Hepatitis B virus (HBV) is transmitted primarily by sexual contact and intravenous drug use. Transmission in a health care setting occurs through contact with blood from an infected patient or health care worker, usually via a needle-stick injury.6

OSHA’s Standard Precautions and Body Substance Isolation includes all body fluids and substances. As this is federal law, a neurodiagnostic technologist may not elect to provide a lower level of disinfection for electrodes.7
