Reusable medical devices pose a risk of infection through cross-contamination
Hospital-acquired infections (HAIs) are among the most frequent adverse events occurring in healthcare. Besides causing considerable discomfort for patients, they also cause significant economic burden on healthcare systems.1,2
On any given day, about one in 25 hospitalized patients has at least one healthcare-associated infection.1
Did you know ...
Electroencephalography (EEG) cup electrodes are available in both reusable and single-use versions. The single-use version makes it possible to minimize the risk of cross-contamination.3
Before applying EEG cup electrodes to the scalp, the skin is cleaned and abraded to remove the epidermal layer of the skin.4,5 Because of the abrasion EEG cup electrodes are categorized as semi-critical devices. They require high-level disinfection (HLD) or sterilization.6,7
If EEG cup electrodes become contaminated because of inadequate cleaning and are used on a patient, there is a risk of infection.
Total cost of reusable EEG cup electrodes
To identify the total cost of using reusable EEG cup electrodes, both Cost of Use and Cost of Clinical Outcome must be determined.

The rate of contamination and risk of sepsis
A 2018 study investigating pathogen growth and the risk of contamination on cleaned, ready-to-use EEG cup electrodes. The study revealed that 1 out of 4 EEG cup electrodes harboured bacteria. 88% (7 of 8) of the bacteria identified were categorized as potential or at-risk of infections.8

Sepsis is a severe syndrome that can lead to tissue damage, organ failure, and death, and it is very expensive to treat. 11% of all sepsis cases start with a skin infection.9,10
Cost of Clinical Outcome (risk of infection)
To identify the risk of sepsis, a systematic study was designed using data from Truven Health Analytics, with a total of 73,834 patients.11 The patients investigated had two outpatient visits; at the first visit, the patient did not have an EEG procedure; at the second visit, the patient received an EEG procedure. The incidences of sepsis were identified 14 days after the two visits, respectively.
- 0 patients had sepsis 14 days after the non-EEG visit
- 24 patients had sepsis 14 days after the EEG procedure
(33 cases per 100,000 EEG procedures – 0.033 %)
The cost of sepsis was identified via a review assessing the hospital-related cost of sepsis. More than 9 million patients were included. The mean hospital-wide cost of sepsis per patient was USD 33,718.9
Cost of use
Based on studies from 4 US hospitals, where all 4 were using HLD as the cleaning method, the combination of acquisition and cleaning costs equates to an average of approximately USD 9 per use. Costs vary from hospital to hospital. At one hospital, the combination of acquisition and cleaning costs was more than USD 15 per use.
Collected data included:
- Costs related to acquisition
- Time spent on cleaning
- Cleaning of the electrodes
The acquisition cost per procedure was estimated at USD 18.50 for single-use EEG cup electrodes (Ambu® Neuroline Cup).
