- A urinary catheter inserted during hospitalization but not removed at discharge is associated with high 1-year mortality in older adults (age ≥65 years) with diabetes and urinary retention.
- Leaving the catheter in is a common practice.
Why this matters
- Diabetic voiding dysfunction (“diabetic cystopathy”) affects >50% of older adults with diabetes.
- Retrospective study including 327 consecutive older adults with urinary retention who had a catheter inserted during hospitalization.
- 42.5% (n=139) had diabetes.
- Funding: None disclosed.
- Most in both groups were discharged with the catheter in place (66.2% with diabetes vs 75.5% without; P=.082).
- Overall, 38.8% with diabetes and 27.7% without died within 1 year of discharge:
- OR: 1.66 (P=.042).
- Among those with diabetes, 1-year mortality was significantly higher with a catheter at discharge vs without:
- 48.9% vs 19.1%.
- OR, 4.04 (P=.001).
- No 1-year mortality difference by catheter at discharge in those without diabetes (26.8% vs 30.4%; OR, 0.83; P=.705).
- After adjustments, 1-year mortality was independently associated (HRs) with:
- Catheter at discharge: 2.56 (P=.019).
- Age: 1.04 (P=.021).
- Cancer: 2.72 (P=.007).
- Small cohort.
- No data on variables such as nutritional/functional status, diabetes control/duration, or out-of-hospital catheter removal.
- No controls without a catheter.
