lthough much guidance indicates that indwelling urinary catheters should only be used for the management of urinary retention and incontinence as a last resort, approximately 10% of care home residents have them, leading to increased risks of catheter associated infections and mortality. Catheterisation rates and subsequent infections can be reduced through more proactive management of incontinence and toileting, and removal of urinary catheters from residents discharged from hospital. Staffi ng in care homes should match residents' nursing and continence needs to allow this proactive approach. Audit of care home should and hospital discharge catheterisation rates, combined with feedback and staff training will raise awareness of the benefi ts of reducing catheterisation rates. Use of the Department of Health's Essential Steps to Safe, Clean Urinary Catheter Care (2006a) will also help to reduce catheter associated infections.
How common are urinary catheterisation and associated infections in care homes? Prevalence of incontinence and urinary catheterisationIndwelling urinary catheterisation may be used to manage urinary retention and incontinence after alternative methods of management have been considered. Urinary incontinence caused by urinary obstruction, neurological abnormality or dementia, is present in about 50% of the elderly population, ( Brocklehurst, 1993 ;Sommer et al, 1990 ) and 34-70% of residents in care homes ( Georgiou et al, 2001 ;McNulty et al, 2006a ). Recent surveys in UK care homes found that about 10% of residents in registered homes had long-term urinary catheters ( Georgiou et al, 2001 ;McNulty et al, 2003 ). There is however a wide variation in the prevalence of catheterisation, ranging from zero to over 40% ( Georgiou et al, 2001 ;McNulty et al, 2003 ). Catheterisation rates are higher in nursing homes (10%) than residential homes (5%), ( Georgiou et al, 2001 ) and lower in those caring for residents with dementia (5%) ( McNulty et al, 2003 ). Although you would expect homes with higher catheterisation rates to have more residents with greater degrees of dependence and incontinence, studies have not shown this ( McNulty et al, 2006a ).
Risk of infection with urinary catheterisation in care homesA recent Norwegian survey found that 78% of care home residents were aged >81 years. ( Eriksen et al, 2007 ) The elderly population are at increased risk of infection, due to decreased immunity and increasing often complex medical problems. In a prospective study researchers recorded the rate of healthcare associated infections (HCAI) in Norwegian care homes. The overall rate of new HCAIs was 0.5% of residents per day. ( Eriksen et al, 2007 ) Antibiotics were given in 94% of episodes of infection. Urinary tract infections (UTIs) formed 38% of the HCAIs. Residents with indwelling catheters were twice as likely to have a symptomatic UTI. The most recent data on prevalence of catheter related UTI from US nursing homes comes from Tsan et al who undertook a point prevalence survey of all infections ...
