Inflammation or infection of the urinary tract is considered to be a critical and common condition that can affect vast numbers of
patients yearly. Inappropriate antibiotic prescriptions lead to an increased risk to patients whom can face bacterial resistance. The
main aim was to investigate the frequency of this infection and the antibiotic-treatment schemes and errors. A retrospective study
was done in three months' time period during 2019 in the out-patient and in-patient clinics at King Abdulaziz Hospital in Makkah
(KAH) in the Kingdom of Saudi Arabia. In general, (1,556) subjects have been diagnosed with this infection, consisted of children
(13.7%), grown-ups (77.5%), and seniors (8.9%) subjects. 88.7% was the total frequency of these subjects attended clinics. Widespectrum
of empirical antibiotics was endorsed for 80% of the subjects. The total wide-spread of antibiotic endorsement with at
least one type of error was 45.2% (children 52%, grown-ups 45%, and seniors 46%). The most common mistakes were found in dose
(38%), length of the treatment (9%), repetition (5%), and the choice of the antibiotic (3.5%). Mistakes in the dosage were significantly
higher in children. However, misfolds in the treatment duration were greater in the seniors. Urine cultures of positive results were
found in 31.50 % of patients, with Escherichia coli at high rates (77%). In conclusion the findings showed a large degree of misuse
use of antibiotics in the care of UTIs at King Abdulaziz Hospital in Makkah, Saudi Arabia.
