Clean Without the Strain: An Ergonomic Solution for Bed Base Sanitization

Challenge Overview

Environmental Services (EVS) staff routinely clean patient bed bases to remove debris, visible contamination, and potentially infectious material before applying disinfectant. The task often requires repeated bending, squatting, reaching, and working in awkward positions underneath and around complex bed components.

Bed bases are cleaned at least weekly and following each patient discharge. At Vancouver General Hospital alone, there are approximately 840 beds, with an average of about 120 patient discharges each day, making cleaning bed bases a frequent and physically demanding task.

This challenge invites students to explore a more ergonomic and effective way to clean and disinfect patient bed bases while allowing staff to remain standing whenever possible.

The Problem

Current bed base cleaning commonly involves manually wiping surfaces with disinfectant-saturated microfiber cloths. Staff must bend or squat to reach underneath the bed and navigate around structural components, wheels, cables, and other difficult-to-access areas.

The repetitive nature of the task, combined with awkward postures and extended reaching, can contribute to fatigue, discomfort, and musculoskeletal strain. These demands can be especially challenging for staff with temporary or permanent physical restrictions, including employees participating in modified return-to-work programs.

A modified commercially available cleaning tool has been tested as a workaround. It allows some cleaning to be completed from a standing position and has been helpful for staff who have difficulty bending or squatting. However, the tool does not provide the dexterity, control, or ease of use achieved through cleaning by hand. These limitations have prevented broader adoption by the EVS team.

The Opportunity

How might we enable EVS staff to thoroughly clean and disinfect patient bed bases from a safer, more comfortable working position without compromising cleaning quality or workflow efficiency?

There is an opportunity to develop an ergonomic cleaning solution that:
-Reduces the need for bending, squatting, kneeling, and extended reaching
-Reaches around and underneath complex bed components
-Provides sufficient dexterity, control, and surface contact
-Supports debris removal, cleaning, and disinfection
-Is intuitive enough to encourage routine use by a broad range of staff
-Integrates naturally into existing hospital cleaning workflows

The objective is not simply to extend a conventional cleaning handle. A successful solution must offer a meaningful improvement in maneuverability and effectiveness so that staff choose to use it rather than reverting to cleaning by hand.

Design Considerations

• Ergonomics: Minimize bending, squatting, kneeling, twisting, overreaching, and sustained awkward postures
• Dexterity and maneuverability: Navigate around wheels, frames, supports, cables, and other bed components
• Cleaning effectiveness: Maintain adequate contact with surfaces to remove debris, blood, and other visible contamination
• Disinfection compatibility: Support appropriate application of hospital disinfectants without interfering with required surface coverage or contact time
• User control and feedback: Allow staff to position the cleaning surface accurately and apply appropriate pressure
• Reach and adjustability: Accommodate different bed designs, bed heights, room configurations, and user body dimensions
• Cleaning-surface retention: Securely hold microfiber cloths, pads, or other approved cleaning materials during use
• Cross-contamination prevention: Allow cleaning surfaces to be changed easily between beds or cleaning zones
• Tool cleanability: Be easy to clean and disinfect after use, without inaccessible joints or surfaces that collect contamination
• Chemical and material compatibility: Withstand repeated exposure to hospital cleaning agents and disinfectants
• Durability: Tolerate frequent use in a demanding healthcare environment
• Ease of use: Require minimal setup, training, maintenance, and physical effort
• Storage and portability: Be compact enough to transport on cleaning carts and store within existing EVS spaces
• Workflow compatibility: Avoid increasing room turnover time or adding unnecessary process steps
• Bed protection: Avoid damaging bed surfaces, coatings, electrical components, cables, or mechanical systems
• Inclusive design: Support users with a range of physical abilities and work restrictions
• Notably, direct observation and consultation with EVS staff will be important and provided to understand the range of beds, surfaces, cleaning motions, access constraints, and workflow conditions the solution must accommodate.

Potential Directions (not prescriptive)

Student teams may investigate a range of approaches, including:
-A more dexterous manual cleaning tool with an articulated or multidirectional head
-A low-profile cleaning device capable of reaching underneath bed structures
-Flexible, conformable, or shape-adaptive cleaning surfaces
-Adjustable or telescoping handles suited to different users and bed configurations
-Interchangeable cleaning heads for different surfaces or areas of the bed
-Mechanisms that improve control, surface contact, or pressure while cleaning
-Designs that allow microfiber cloths or disposable cleaning materials to be attached, removed, and replaced without direct handling
-Features that provide tactile or visual feedback confirming adequate surface contact
-Semi-assisted devices that reduce physical effort while preserving operator control
-Alternative cleaning techniques or workflow changes that reduce the need to access bed bases manually
-Modular systems that can be adapted to different hospital bed designs

Teams are encouraged to first examine the current workflow, test relevant commercial tools, and identify why existing products do not adequately address this application before selecting a design direction.

Cost Awareness & Benchmarking

Proposed solutions should be evaluated not only for technical performance but also for their affordability, durability, and likelihood of adoption in healthcare environments.

Important considerations include:
-Purchase and implementation costs relative to conventional cleaning tools
-Ongoing costs for replacement pads, cloths, consumables, maintenance, or repairs
-Expected service life under frequent hospital use
-Staff time required to prepare, use, clean, and store the solution
-Potential effects on discharge cleaning and room-turnover times
-Compatibility with existing microfiber cloths, disinfectants, cleaning carts, and EVS processes
-Training requirements and the likelihood that staff will consistently use the solution
-Whether the solution can be retrofitted or adapted rather than requiring replacement of existing equipment
-Scalability across different hospital units, bed types, and healthcare facilities
-Existing commercial cleaning products and the specific performance gaps that distinguish the proposed solution

The submitter estimates that Vancouver General Hospital incurs approximately $400,000 annually in injury-related claims overall, with back injuries representing a significant concern and physically demanding tasks such as bed base cleaning and linen handling identified as contributing ergonomic issues. Student teams should validate the relevant injury, modified-duty, staffing, and operational costs when developing an economic case for a proposed solution.

A successful concept should offer a clear value proposition by balancing procurement cost with usability, cleaning performance, injury prevention, durability, and potential operational savings.

Impact

A successful solution could:
-Reduce bending, squatting, kneeling, and awkward reaching during bed base cleaning
-Lower the risk of discomfort, fatigue, and musculoskeletal injury among EVS staff
-Make the task more accessible to employees with temporary or permanent physical restrictions
-Improve staff comfort, safety, and confidence
-Support more thorough and consistent cleaning and disinfection
-Encourage adoption of safer cleaning practices without compromising room-turnover efficiency
-Reduce costs associated with injuries, modified duties, absenteeism, and staff replacement
-Improve productivity and operational efficiency within EVS departments
-Provide a scalable solution for hospitals and other healthcare facilities
-Recognize the essential contribution of EVS staff to infection prevention, patient safety, and quality of care
