Key principles of showering and toileting aids
Showering and toileting aids increase the risk to skin integrity because:
- The person is naked, with skin exposed, when using or transferring onto the equipment.
- Most commodes, toilets and benches with apertures have a reduced seating surface area, increasing the risk of pressure injuries.
- Many bathrooms offer less circulation space, increasing the difficulty of toilet transfers.
- Shower commodes have a higher seat clearance, increasing the difficulty of toilet transfers.
- Machine-made seats have limited padding or heat-welded seams, that can leave sharp edges.
- The equipment in wet and slippery, creating fall risks.
Common problems with showering and toileting aids
- Dry trials: Testing bathroom equipment before use, known as ‘dry trials’, does not allow for an accurate comparison of use in wet conditions, where the person will be naked, wet, sitting for a prolonged time and reaching or leaning to carry out self-hygiene.
- Padding: Consider the need for padded equipment for people who have sensory deficits, including benches and toilet seats.
- Shear and friction: Can occur during repositioning, while performing repetitive bowel tasks.
- Sacral pressure: Positioning the sacrum on the rear of the seat aperture increases stability but increases pressure over the sacral region.
- Natal cleft stretching or splitting: This can occur because of too much weight shift and movement forward into the aperture, usually due to poor posture or the aperture being too big.
- Reduced stability and balance in an upright position: Positioning stability can be achieved with an appropriate combination of thigh, trunk and leg support. Seat-to-backrest angle, tilt-in space function, armrests and leg rest supports should all be considered to achieve stable seating in a commode.
- Poor equipment maintenance: See ‘Showering and toileting equipment maintenance checklist‘ below.
Ischial pressure: Skin breakdown can occur when the ischial bones make contact with the internal rim at the side or front. This can be a result of inappropriate aperture shape and size or postural changes. The risk is higher with poor quality seat padding at the aperture.
Side opening seats: A complete cut-out of the seat and frame creates corners that cause points for increased pressure. An alternative could be a ‘bite’, which enables the person to reach close to their thigh for hygiene and toileting needs as well as retain pressure distribution over the thigh.
It is important to maintain equipment and to check for:
- Brittleness of the vinyl, where it loses stretch and conformity. This may appear as creases or cracks in the covering.
- Exposure of the baseboard, often along the inner rims of apertures where foam has lost resilience. Clinicians can assess this through palpation of the foam.
- Damage to the foam, such as water ingress. Damage can be noted when air is expressed from the seat when sitting on it, as visible compression of the foam.
