The UriCath study: characterization of the use of indwelling urinary catheters among hospitalized older patients in the Internal Medicine Departments of Portugal

Intermittent catheterisation

When an individual has voiding difficulties, the person may require a urinary catheter. Enabling the person to choose an appropriate method of catheterisation and supporting them can have an enormous impact on the individual's health and wellbeing. Indwelling urethral catheters are suitable for some people but for others they can affect a person's lifestyle and lead to depression. Intermittent catheterisation can work well for some people. Intermittent self-catheterisation has been used to manage urinary retention for over 3500 years. It remains the 'gold standard' in terms of bladder drainage, but it is under-used and indwelling catheters remain more common. This article examines the history of intermittent catheterisation, indications for self-catheterisation and how to support people to use self-catheterisation.

Urinary retention in diabetic older adults: mortality associated with a urinary catheter inserted during hospitalization but not removed

PURPOSE

We have studied, in diabetic older adults with urinary retention (UR), whether a urinary catheter (UC) inserted during hospitalization but not removed is associated with 1-year mortality.

METHODS

A retrospective study included 327 consecutive older adults (age ≥ 65 years; median age 83 years; 57.8% males) with UR in whom a UC was inserted during hospitalization: 139 (42.5%) diabetics and 188 (57.5%) nondiabetics. UC removal rates during hospitalization and 1-year mortality rates were studied in both groups. Cox regression analysis was used to assess whether a UC inserted during hospitalization but not removed was independently associated with 1-year mortality.

RESULTS

Most diabetic and non-diabetic patients left the hospital with a UC (66.2% vs. 75.5%; p = 0.082). Overall, 54 (38.8%) diabetic patients and 52 (27.7%) nondiabetic patients died one year later (OR 1.66; 95% CI 1.04-2.65; p = 0.042). Diabetic patients with a UC at discharge day had significantly higher 1-year mortality rates relative to diabetic patients without a UC (48.9% vs. 19.1%; OR 4.04; 95% CI 1.75-9.30; p = 0.001), while in nondiabetic patients there was no significant difference in 1-year mortality rates between patients with or without a UC at discharge day (26.8% vs. 30.4%; p = 0.705). Cox regression analysis showed that only in diabetic patients a UC not removed was independently associated with 1-year mortality (HR 2.56; 95% CI 1.16-5.64; p = 0.019).

CONCLUSION

A UC inserted but not removed in diabetic older adults with UR is associated with 1-year mortality. Removing a UC and its association with mortality should be studied prospectively in this population.
