Healthcare-associated infections (HAIs) are infections associated with the treatment of patients in healthcare settings, which were not originally present on the patient’s admission.¹ This means a patient acquired a new infection from their healthcare stay or treatment.

The Most Frequent Medical Adverse Event

HAIs are the most frequently occurring medical adverse event worldwide, with a prevalence of around 7-10%.^2,3

There can be serious physical and emotional impacts to patients that acquire an HAI.⁴ Facilities and practitioners may also suffer financial as well as reputational damage as a result of HAIs associated with their facility.

HAIs Add Considerable Cost to Delivering Healthcare

HAIs cost the U.S. healthcare system billions of dollars.⁴ Each year, 3-5% of hospitalized patients will acquire a HAI in the United States.^2,4,5

HAIs are Preventable

A systematic review and meta-analysis found 35-55% of HAIs are preventable with existing multifaceted infection prevention and control interventions, regardless of a country’s income level.⁶

The Role of Medical Devices in HAIs

Sterilization and disinfection of medical devices play an important role in the prevention of HAIs. Multiple studies document failures in medical device reprocessing, some of which have led to outbreaks and patient exposure.^7-9

The CDC and U.S. Food and Drug Administration (FDA) released a Health Alert in 2015 urging healthcare facilities including hospitals, ambulatory surgical centers, clinics, and doctors’ offices, review all reusable medical device reprocessing practices.¹⁰

In 2017 the Joint Commission released a Quick Safety Alert that reported 74% of all immediate threat to life declarations (ITLs) were from improper sterilization or high level disinfection (HLD) of reusable medical devices.¹¹ Noncompliance with TJC infection control standards had increased in hospitals, critical access hospitals, ambulatory and office-based surgery facilities.¹¹

Population Level Study: Infection Risk after Ultrasound

In the first of its kind, a study commissioned by UK National Health Authorities (Scotland) revealed an "unacceptable risk" of patient infection following ultrasound. The study revealed an increased infection risk in the 30 days following endocavitary ultrasound. Commissioned by a national health authority, the study revealed an increased infection risk in the 30 days following endocavitary ultrasound.¹²

90.5% of facilities were not performing HLD of these probes at the time of the study.

The increased rates of infection risk following transvaginal ultrasound were startling:¹²

Prevent HAIs from Medical Devices

The Spaulding Classification identifies the level of disinfection or sterilization required for medical devices based on the expected patient tissue the device will contact.

The Spaulding Classification forms the basis of international ultrasound probe reprocessing guidelines.

Internationally, Federal authorities and professional societies provide guidance on the proper reprocessing of ultrasound probes, to help keep patients safe from HAIs.

These guidelines are based on The Spaulding Classification.
