Accurate and timely assessment of a critically ill patient’s skin is extremely important in preventing pressure injuries from occurring or worsening, and monitoring treatment effectiveness. Students on the Stryker team will design and prototype a device(s) that allow a nurse to access key areas of a patient’s skin with minimal movement of the patient, and minimal effort by the nurse.

Abstract:

Pressure Injuries in the ICU

Pressure injuries, previously called pressure ulcers or bed sores, result from prolonged pressure on the skin. ICU patients in the hospital have multiple factors that make pressure injuries a particularly challenging problem in this environment. Some examples include reduced mobility, fragile skin, medical devices, certain medications, contraindications, nursing priorities, and availability.  

Stryker in the ICU:

For the purposes of this project, assume the patient is laying on a Stryker ProCuity hospital bed that has an Isolibrium support surface.  Some of the features of both products are highlighted below:

Impact:

Stryker, together with its customers, is driven to make healthcare better. Stryker is one of the world’s leading medical technology companies, and a Fortune 500 company, based in Kalamazoo, MI.  One of Stryker’s goals of making healthcare better is by preventing pressure injuries.  

Pressure injuries, previously known as “bed sores”, are literally killing 6.8 people in the U.S. every hour because they can go undetected, misdiagnosed, or poorly treated. The fatalities happen when pressure injuries become an open wound, and develop into deadly infections. Pressure injuries cost the US Healthcare system an estimated $9.1-$11.6 billion annually, with the average cost of a pressure injury ranging from $20,900 – $151,700 depending on severity.  What makes these numbers challenging for hospitals is that hospital-acquired pressure injuries are considered “never events” by nearly all insurance companies and Medicare/Medicaid.  That means hospitals do not get reimbursed for these costs. Lastly, hospital-acquired pressure injuries are the 2nd most common cause of civil suits alleging medical malpractice.

Scope:

Minimum Viable Product Deliverable (Minimum level of success)

  • Design and prototype a concept that allows a clinician to access common locations of a pressure injury when the patient is lying flat and supine, while minimizing the amount of movement of the patient, and decreasing the effort required by the nurse.  Common locations for pressure injuries are the sacrum, coccyx, spine, scapula, and heels.  The design should factor in various skin tones and body morphologies
    • Complete literature/background review that includes basic understanding of pressure injuries, how they are assessed in a hospital, and the challenges with assessments
    • Complete literature/background review that includes current internal Stryker knowledge, and competitive technologies
    • Determine system requirements
    • Brainstorm multiple concepts to address the problems
    • Choose the best concept, and develop a basic prototype

Expected Final Deliverable (Expected level of success)

  • Obtain feedback on the basic prototype function from multiple stakeholders, and incorporate these into a refined second version of the prototype  
  • Validate the performance against the requirements

Stretch Goal Opportunities: (High level of success)

  • The concept may also add a way to include the following use cases:
    • Raise the head of the bed to 30 degrees, which is a common angle for patients in the ICU.  To counteract the tendency for the patient to slide down in bed, the thigh section should also be raised to 15 degrees 
    • In addition to minimizing the effort by the nurse, the added time to accomplish the task should be minimized
Below are the skills needed for this project. Students with the following relevant skills and interest, regardless of major, are encouraged to apply! This is a team based multidisciplinary project. Students on the team are not expected to have experience in all areas, but should be willing to learn and will be asked to perform a breadth of tasks throughout the two semester project.
