Mobile devices are among the most frequently touched objects in clinical environments. They move from room to room, shift to shift, and clinician to clinician. They are used to access EHRs, verify medications, and coordinate care. Yet when hospitals evaluate device accessories, infection control is rarely the first question asked. Cost, compatibility, and drop protection tend to lead the conversation.
Obviously, those factors are important. But in a patient care environment, the material covering a device and how easily it can be disinfected are important compliance considerations, not just purchasing preferences.
The Case Is a Clinical Surface
A device case isn't a passive accessory. In a patient care area, it's a surface subject to the same infection control logic as any non-critical item that contacts the environment. The CDC's Guideline for Disinfection and Sterilization in Healthcare Facilities classifies mobile device cases as requiring low-level disinfection with an EPA-registered hospital disinfectant,which can wreak havoc on normal consumer cases.
The CDC estimates that healthcare-associated infections affect 1.7 million patients annually in U.S. hospitals and contribute to approximately 100,000 deaths each year — with environmental surfaces and shared devices among the recognized transmission pathways. A 2014 study from Northeastern University found that nosocomial pathogens including MRSA were recovered from the surfaces of iPads used in clinical settings, with MRSA detected on 64.3% of hospital-setting devices. An APIC issue brief on non-critical medical device contamination found that across 13 qualifying studies, between 23% and 100% of portable clinical items were contaminated, with up to 86% harboring pathogenic organisms.
A case that can't withstand your facility's disinfectants or whose design makes thorough cleaning impractical, fails at one of its most important functions and increases the risk of infection for already vulnerable populations.
What to Evaluate, and Why
Chemical compatibility. The first question is also the most foundational: can the case be cleaned with what your facility actually uses? Bleach-based solutions, isopropyl alcohol, hydrogen peroxide, and quaternary ammonium compounds are standard in clinical environments, and they're chemically aggressive. Consumer-grade silicone and TPU materials can degrade, swell, or become tacky with repeated exposure. Ask whether the manufacturer has tested their product against the specific disinfectants in your formulary, under conditions that reflect real-world use .
Material certification. Healthcare-grade polycarbonate should meet FDA requirements and pass testing under ISO 10993 biocompatibility standards, including cytotoxicity and sensitization testing. Consumer plastics carry no such assurance. Material certification is the clearest signal that a manufacturer has considered where their product will be used.
Surface design. A chemically compatible case can still fail infection control if its physical design makes disinfection impractical. Deep grooves, textured surfaces, rubber inlays, and recessed ports trap contaminants that a wipe can't reach. The CDC's environmental infection control guidelines emphasize that non-critical surfaces should be designed to facilitate cleaning. Smooth, sealed surfaces with minimal seams allow full contact with a disinfecting agent. A case that traps debris in seams is a reservoir for bacteria.
IP rating. An IP54 rating indicates protection against dust interference and water splashed from any direction. For clinical environments — where devices encounter spills, splashes, and routine cleaning — IP54 should be confirmed through independent, third-party testing.
Drop protection. Surface discontinuities, such as cracks, chips, and stress fractures create harboring sites for pathogens and compromise the seal between case and device. MIL-STD-810 is the standard reference for drop testing, but a claim of "military-grade protection" should always be accompanied by actual test conditions: drop height, surface type, and number of drops.
Screen protection. Cracked screens create sharp-edge hazards and surfaces that are effectively impossible to disinfect. Research published in the American Journal of Infection Control recommends waterproof barriers and routine disinfection of mobile handheld devices as part of point-of-care infection prevention. An integrated screen protector should maintain full touch sensitivity for EHR navigation and barcode scanning, because a protector nurses remove to do their jobs isn't protecting anything.
Compliance Requires Organizational Process, Not Just Product Selection
Even the right case will underperform without clear protocols for when and how devices are cleaned, who owns the device fleet, and how compliance is tracked. The Joint Commission's revised Infection Prevention and Control requirements, effective July 1, 2024, emphasizes evidence-based practices aligned with CDC Core Infection Prevention guidelines, including for mobile devices.
In practice, infection prevention and clinical engineering should be part of the accessory selection process alongside IT and procurement. That conversation is much easier to have before a fleet of non-compliant cases have already been deployed.
A few principles that hold regardless of organization size:
- Bring your IP or IPC professional into the evaluation early;
- Request disinfectant compatibility documentation and material certifications before committing; and
- Test evaluation units against your actual disinfectant formulary.
A Note on Battery Management
Battery management may seem unrelated to infection control, but the connection is practical. When devices die mid-shift, staff improvise by leaving devices at nurses’ stations to charge, sharing outside normal handoff protocols, or even bringing personal cables onto the unit. Each workaround introduces variables into the device's hygiene chain.
A swappable battery system addresses this directly. When a nurse can swap to a fully charged battery in seconds without removing the case or logging out, devices stay with the clinician, within normal workflow, and within the expected disinfection cycle.
The difference in cost between a compliant accessory and a non-compliant one is almost always smaller than the cost of redeployment after a fleet fails inspection, degrades under disinfectants, or contributes to a device reliability problem mid-shift.
