The effect of urinary bladder catheterization on patient care in an internal medicine department.

INTRODUCTION

Recommendations for urinary catheterization in newly hospitalized patients are inconsistent and unclear.

METHODS

The authors studied prospectively consecutive patients who were catheterized in an internal medicine department over a 3-month period, with follow-up for 6 months or until the catheter was removed. Patient records were reviewed to determine if catheterization was definitely not indicated by commonly accepted criteria. After chart review, a category of possibly not indicated was defined as having no demonstrable effect on patient care.

RESULTS

There were 17.7% patients (122/691) catheterized during their admission. According to accepted criteria, definite inappropriate catheterization occurred in 18 patients (14.7%). There were an additional 69 patients (56.6%) with unclear clinical benefits, hospitalized because of fever, acute congestive heart failure, a cerebral vascular accident or respiratory insufficiency due to exacerbation of chronic obstructive lung disease. During hospitalization, attempts to remove the catheter failed in 13 patients, 4 of who remained with the catheter permanently, complicated by urosepsis in 1 patient.

CONCLUSION

Over 50% of the patients had acceptable indications for catheterization but no demonstrable benefit from the procedure. In such patients, the uncertain benefits of catheterization should be balanced by potential complications. Additional studies are warranted to determine the effect of acute urinary catheterization on patient care.
