Coraltoes - provision of sufficient quality and quantity of incontinence supplies may be more expensive in the short term, but can lead to savings in the longer term.
Someone who cannot be changed as often as they need, and whose incontinence supplies do not keep their skin as dry as possible may well develop sores/ulcers. They may already be more prone to these if their mobility is reduced (ie bed/chair bound).
Someone who gets sores because of staying wet/dirty for too long will take longer to heal - because the sore will continue to be wet/soiled whenever the person urinates/defaecates - and the poor quality/quantity of their incontinence supplies won't have changed either, which will exacerbate the problem.
If their mobility is reduced, the pressure on their bottoms due to immobility also makes these sores far slower to heal (pressure reduces oxygen supply to the tissues which can cause breakdown in the first place and retards healing).
All this means more NHS time, care and supplies will be needed to treat the sores - even hospital treatment, if they are really bad/slow to heal. The costs of this need to be set against the costs of providing decent incontinence supplies.
Prevention is better than cure, surely??!
