Aims : The study aims to determine the: 1. frequency of inappropriate catheterization in medical wards and the reasons for doing it. 2. various risk factors associated with inappropriate catheterization, catheter associated urinary tract infections (CAUTI) and bacterial colonization on Foley's catheters (BCFC). Settings and Design: Hospital-based prospective study. Materials and Methods: One hundred and twenty five patients admitted consecutively in the medical wards of a tertiary care hospital, who underwent catheterization with a Foley's catheter, at admission, have been included in the study. Patient profiles were evaluated using the following parameters: age, sex, diagnosis, functional status, mental status, indication, duration and place of catheterization, development of BCFC and CAUTI. Statistical tests used: Chi-square test. Results: Thirty-six out of 125 (28.8%) patients included were inappropriately catheterized. BCFC developed in 52.8% and 22.4% were diagnosed with a CAUTI. The most frequent indication for inappropriate catheterization was urinary incontinence without significant skin breakdown (27.8%). The risk factors for inappropriate catheterization were female sex (RR=1.29, 95% CI=0.99, 1.69, P<0.05) and catheterization in the emergency (RR=0.74, 95% CI=0.61, 0.90, P<0.05). The risk factors for developing a BCFC were age>60 years (RR=0.65, 95% CI=0.48, 0.89, P<0.05), non-ambulatory functional status (RR=0.57, 95% CI=0.39, 0.84, P<0.01), catheterization in the emergency (RR=2.01, 95% CI=1.17, 3.46, P<0.01) and duration of catheterization>3 days (RR=0.62, 95% CI=0.43, 0.89, P<0.01). The risk factors for acquiring a CAUTI were age>60 years (RR=0.47, 95% CI=0.25, 0.90, P<0.05), impaired mental status (RR=0.37, 95% CI=0.18, 0.77, P<0.01) and duration of catheterization>3 days (RR=0.24, 95% CI=0.10, 0.58, P<0.01). Conclusions : Inappropriate catheterization is highly prevalent in medical wards, especially in patients with urinary incontinence. The patients catheterized in the medical emergency and female patients in particular are at high risk. Careful attention to these factors can reduce the frequency of inappropriate catheterization and unnecessary morbidity.
