Background

Pressure ulcers

Pressure ulcers afflict people of all ages across the globe and are one of the most common injuries suffered by patients in the course of care. A pressure ulcer is an injury to the skin and/or underlying tissue caused by insufficient blood flow as a result of pressure on the skin, for example, due to extended periods of laying or sitting.  The pressure deprives the cells of the oxygen and nutrients they need. Pressure ulcers are the cause of tremendous suffering, high healthcare costs and can occasionally lead to death. Approximately 15% of all patients in Swedish hospitals are afflicted by pressure ulcers. This results in costs amounting to several billion krona in Sweden alone.

Risk assessment

There are preventative measures that can help. Therefore, patients undergo a risk assessment when admitted to hospitals and care homes according to established methods; usually through the application of assessment scales. Those patients who are assessed to have the greatest risk of developing pressure ulcers are the most likely to be treated using preventative measures.  However, about half of all pressure ulcers in Sweden occur in patients who were not assessed to be in the high risk category. This means that current risk assessment methods are not as reliable as they need to be. It also means that the number of patient’s suffering from pressure ulcers would be lower if we were able to better identify those that fall into the risk group.

PUsensor’s method and technique

Assessment scales are widely used, but these are not very precise since they rely on an assessment of the patient’s condition and are rather subjective. The method and technique our PUsensor uses is based on an assessment of the individual’s physiological status, through an examination of the patient’s superficial blood flow in places where pressure ulcers tend to occur, and the skin is bearing the patient’s body weight.

Product

Blood flow assessment

The PUsensor uses a proprietary method and instrument to assess blood flow in the superficial tissue. The technique is based on Photoplethysmography (PPG), which is a procedure where the skin is illuminated, and the reflected light is measured. This is an established technology that is used in heart rate monitors (HRM watches) and other devices.(t04).

The PUsensor has a sensing unit that is built in to a thin, soft disc that is applied to the back. The device’s proprietary, patent-pending method allows medical professionals to evaluate blood flow with and without the application of the patient’s body weight. The medical instrument works independently, and the method does not require staff monitoring while in use. A built-in algorithm then evaluates the comparative measurements and generates an assessment of the patient’s risk profile based on blood flow.

Effects

The ability to better predict which patients are at risk of developing pressure ulcers allows professionals to apply preventative measures with a greater degree of accuracy. This allows care providers in hospitals and care homes to take preventative measures where they are needed most. This offers a host of benefits for the patient, the healthcare sector and society.

Reduced suffering

Individuals who are spared the suffering caused by pressure ulcers have a greatly increased quality of life and avoid the risk of complications caused by pressure ulcers. The duration of care is also reduced, and the individual is able to get back to their regular routines more quickly.

Properly focused care

By reducing the occurrence of pressure ulcers, a patient’s treatment can focus on the illness or injury that gave rise to the need for care in the first place, rather than on new injuries arising during the delivery of care. Greater accuracy in risk assessments allows pressure ulcer prevention methods to be focused on the patients who need them most.

Lower costs

By reducing the occurrence of pressure ulcers, we also reduce the cost of care and costs associated with dressing materials used to treat pressure ulcers. Serious pressure ulcers can give rise to the need for surgery and other costly treatment methods. By reducing the number of pressure ulcers, the number of days that care is needed is reduced, and the individual can get back to their regular routines more quickly. Prevention is always less costly than treatment.
