Antibiotics have been considered the most important factors fighting pathogenic bacteria. Nevertheless,
some bacteria have developed a type of resistance against antibiotics these days due to the
inappropriate use of antibiotics. As a consequence, they are able to live and even reproduce when
exposed to antibiotics. Pharmacists play an important role in curbing the antibiotic resistance in patients
in hospitals by limiting the inappropriate use of antibiotics. Besides that, pharmacists also play a role in
counselling and educating patients and other health care professionals such as doctors, pharmacists and
nurses. The research was carried out to investigate the bacterial pattern of antibiotic resistance of
surgical site infection (SSI) and catheter-associated urinary tract infection (CAUTI) and to determine the
appropriateness of antibiotics used in treatment in SSI and CAUTI in surgical unit. This research was in
the form of descriptive analysis study carried out in Dr.Hasan Sadikin Government Hospital (RSHS). The
specimens obtained during this research were pus from SSI patients and urine from CAUTI patients. The
data was collected from patient medical records and laboratory results in the period August 2017 - June
2018. There were 14 subjects for SSI (from total 20 subjects) and 54 subjects (from total 179 subjects)
for CAUTI. In SSI and CAUTI patients in RSHS, it turned out that E. coli (ESBL) was the most common
bacterial pathogen resistant to 3rd generation cephalosporins such as ceftriaxone and cefotaxime at
57.1% for SSI and 40.7% for CAUTI. Resistant bacterial pattern to 3rd generation cephalosporins reported
to be the highest using antibiotic susceptibility test. Chi-square test was used for CAUTI but not for SSI as
the number of SSI patients was limited. It was used to determine the appropriate use of antibiotics with
the bacterial isolates being tested. It was found out that there were more inappropriate antibiotics used
for treatment in CAUTI patients that was 61.1% based on Chi-square test (p=0.000). For SSI patients, the
inappropriate antibiotics used for treatment was 85.7%.
