Definitions

  • the present disclosure generally relates to a method for selecting a predetermined kit of products for a patient at risk of developing pressure ulcers.
  • the present disclosure also relates to an array of products comprising at least a high-risk kit of products and a standard-risk kit of products.
  • a pressure ulcer is a localized injury to the skin and/or underlying tissue over a bony prominence that results from sustained pressure, often in combination with friction and shear.
  • the major factors leading to pressure ulcers are pressure, shear, friction, and unfavorable microclimate.
  • Other factors, intrinsic to patients, may also increase the likelihood of pressure ulcer development, e.g. poor perfusion, reduced sensation, reduced mobility level, and inadequate nutrition.
  • a pressure ulcer typically does not start at the skin surface.
  • Pressure ulcers often develop in soft tissue under the skin which covers bony areas of the body (so called “bony prominences”), for example the heels, ankles, elbows, the hips or the sacrum.
  • bony prominences bony areas of the body
  • Pressure and shear forces cause blood vessels to become squeezed between the skin surface and bone.
  • muscles and tissue under the skin near the bone surface typically suffer the greatest damage. Accordingly, any pressure ulcer as apparent on the skin, regardless of how small, should be regarded as critical because of the probable damage below the skin surface.
  • a pressure ulcer can be classified into four categories: in the first category, the skin appears pink, reddened, or discolored, and may feel hard and warm to touch. In the second category, the skin breaks open and an ulcer that may look like a blister is formed. In this stage, the skin may be damaged beyond repair or may die.
  • a category three pressure ulcer is an ulcer that extends into the tissue beneath the skin, forming a small crater. In category four, the pressure sore is very deep, reaching into the muscle and bone and causing extensive damage to deeper tissue and tendons. Serious complications, such as infection of the bone or blood, can occur if the pressure ulcer progresses.
  • Pressure ulcers are a global problem and the possibility to prevent these is desirable both to reduce human suffering but also to avoid unnecessary costs.
  • the average cost for a category three or four pressure ulcer is estimated to be from 75000 to 125000 US dollars per patient.
  • Pressure ulcers often arise among persons being bedridden for various reasons, e.g. due to hospitalization or other causes of immobility.
  • a method for selecting a pre-determined kit of products for a patient at risk of developing pressure ulcers comprising: a) determining a plurality of risk parameters associated with the patient, wherein the plurality of risk parameters are selected from sensory perception, exposure to moisture, degree of physical activity, mobility, friction and/or shear, skin condition, medication, trauma, fluid and/or food intake pattern, time of hospitalization, perfusion and/or medical condition, b) evaluating, based on the risk parameters, a risk score associated with the patient, c) selecting a pre-determined kit of products, based on the risk score, wherein the pre-determined kit of products is selected from at least a standard-risk kit of products and high-risk kit of products, and wherein the standard-risk kit of products comprises a first, a second and a third prophylactic dressing; the first prophylactic dressing being a sacral dressing; the second and third prophylactic dressings being heel dressings, and wherein the high-risk kit of products comprises
  • the method of the present disclosure significantly alleviates the burden for caregivers, and facilitates the selection of products to be used in a specific care scenario and for a specific patient.
  • Each patient is individually analyzed based on the plurality of risk parameters, and the risk score associated with a specific patient allows for a selection of the appropriate products for that patient.
  • the medical personnel may, after an individual risk assessment, retrieve a score indicating that the patient is in need of a standard-risk kit of products or a high-risk kit of products. Accordingly, significant time and effort is saved for each care scenario and each patient being assessed.
  • the method of the present disclosure offers a proactive approach in preventing pressure ulcers. Instead of waiting until the first symptoms of pressure ulcers arise, a predetermined kit of products aiming at preventing and/or alleviating pressure ulcers is provided. Accordingly, the risk for developing pressure ulcers is minimized. Furthermore, the staff is guided with respect to what products to utilize in a specific care scenario and for a specific patient.
  • the medical personnel may select a high-risk kit of products to be used for the specific patient.
  • the method of the present disclosure offers a possibility to reduce the overall cost for the hospital, clinic or home care facility, and each patient may get a tailored and individualized preventative treatment strategy, that in the end may reduce the treatment needed for that patient.
  • the standard-risk kit of products comprises a first prophylactic dressing being a sacral dressing, and a second and third prophylactic dressing being heel dressings.
  • the sacrum and the heels are areas that have a higher risk of developing pressure ulcers than other areas.
  • the anatomy and physiology of the heels and sacrum make the tissue very vulnerable to pressure.
  • the risk score may be a qualitative score or a quantitative score.
  • the risk score may e.g. be based on the number of risk factors associated with a specific patient.
  • the risk parameter may be associated with at least three levels of sub-scores and wherein the risk score associated with the patient is the sum of each sub-score associated with each risk parameter.
  • the Braden scale is a standardized assessment tool to assess a patient’s risk of developing pressure ulcers, and comprises the following risk parameters: sensory perception, degree of moisture, degree of physical activity, mobility level, food intake pattern (nutrition), friction and shear.
  • Each of the risk parameters mentioned hereinbefore may be associated with an individual sub-score.
  • the risk parameter “degree of activity” may be divided into the four levels: bedfast, chairfast, walks occasionally and walks frequently. Each of these levels may be individually scored between 1 and 4, where 4 denotes the worst scenario; i.e. bedfast (patient being confined to bed).
  • the first, second and third prophylactic dressing is a dressing having anisotropic stiffness properties.
  • the prophylactic sacral and/or heel dressing is preferably “stiffer” in one direction than the other.
  • the prophylactic dressing generally has a lateral (x) extension and a longitudinal (y) extension.
  • the dressing is preferably stiffer; i.e. has a higher tensile force in the longitudinal (y) direction of extension than in the lateral (x) direction of extension.
  • the prophylactic dressing is to be applied such that its longitudinal (y) direction corresponds to the direction of which the patient is exposed to most shear forces; i.e. in the direction in which the patient slides in bed. This is normally along the length of the patient. This way, the pressure and shear forces inflicted on a bed-ridden patient are significantly reduced.
  • the lateral (x) direction of the dressing is preferably more pliable and may have a lower tensile force. This is beneficial since the lateral (x) direction of the dressing corresponds to the direction in which the patient, wearing such dressing, will be turned and re-positioned by nursing personnel. A bedridden patient at risk of developing pressure ulcers must be turned and repositioned at regular intervals. It is therefore advantageous that the dressing conforms to this lateral movement and stays on the skin. Furthermore, the skin and is prevented from becoming “over constrained” which could otherwise be the case when the dressing is stiff in both the lateral (x) and longitudinal (y) directions.
  • the additional prophylactic dressing of the high- risk kit of products is selected from an elbow dressing, a shoulder dressing, and/or a dressing for use in conjunction with a medical device.
  • elbows and shoulders represent bony prominences that are also prone to pressure ulcer development.
  • the various prophylactic dressings may thus be arranged on the most vulnerable parts of the skin of a patient; i.e. the areas overlying the bony prominences of the body.
  • Pressure ulcers may also develop underneath medical devices. Such pressure ulcers are referred to as medical device related pressure ulcers (MDRPU).
  • Medical devices such as feeding tubes, oxygen delivery devices, intravenous catheters, orthopedic devices, tracheostomy tubes and nasogastric tubes are examples of medical devices commonly used in a hospital or medical setting. These devices are designed to be in continuous and close contact with the body, particularly the facial areas of a patient. If a patient is in need of any such medical device, the high-risk kit of products may also include a dressing for use underneath a medical device.
  • the prophylactic dressings of the standard-risk and high-risk kits of products may comprise a pressure-relieving material.
  • the pressure-relieving material may be a gel or a foam.
  • the pressure- relieving material may comprise a polyurethane foam.
  • a polyurethane foam has a pressure relieving and offloading effect and can absorb large amounts of fluids.
  • a bed-ridden patient may have a high degree of perspiration and may also be incontinent. Fluids, such as sweat and urine (and potentially also blood) are efficiently handled by the absorbent and pressure-offloading polyurethane foam material.
  • the prophylactic dressings of the standard-risk and high-risk kits of products comprise a backing layer, an adhesive skin contact layer and a pad arranged between the backing layer and the adhesive skin contact layer; the pad comprising one or a plurality of pad-forming layers, wherein at least one of the pad-forming layers comprises the pressure-relieving material.
  • At least one of the pad-forming layers may be a layer having anisotropic stiffness properties.
  • Such a pad-construction is suitable for use for the first, second and third prophylactic dressings; i.e. the sacral and heel dressings.
  • the additional prophylactic dressing of the high- risk kit of products is an elbow dressing, and wherein the elbow dressing may comprise at least one pad-forming layer provided with a plurality of incisions.
  • the mode of movement of the elbows of a bed-ridden patient is typically different from that of e.g. the sacrum.
  • the sacral region is subject to shear forces as the patient slides in bed.
  • the elbows may move and chafe against the bed surface in multiple directions.
  • the elbow dressing preferably comprises a pad provided with a plurality of incisions which render the dressing flexible in all directions. In this regard, the wear time of the dressing is improved.

  • Such a pressure-offloading pad may offload bony prominences on patients at risk of developing pressure ulcers.
  • the pad may be arranged directly underneath a body part of a patient in a hospital bed to offload the pressure exerted on that body part.
  • it may be used in conjunction with a pressure offloading mattress to angle a patient and hold the patient in a specific position for the purpose of pressure offloading.
  • the fluidized medium preferably has no or limited shape memory such that the pad can conform to the skin of a patient in various positions.
  • a pressure-offloading pad may also be arranged underneath the head of a patient.
  • the back head of the patient is susceptible to pressure ulcers. The same applies to the ears.
