Abstract

Knowledge and perception of rational Antimicrobial Use (AU) help in developing interventions to improve
AU. Data to target AU surveillance and interventions are provided by Point Prevalence surveys, which are
a resource-effective alternative to prospective surveillance. Point Prevalence Survey (PPS) on AU provides
a snapshot of antibiotic use at a given point of time and can be repeated at regular intervals to monitor
trends. It provides data that can be fed back to front line clinicians and used to inform discussions about
stewardship. In Our 670 bedded tertiary care Hospital, we did the PPS during last week of Jan 2019 in the
identified wards and ICU’s. A survey team reviewed patients’ case sheet and noted antibiotics prescriptions
on the date of the survey. Other important details such as admitting ward, age, sex, total number of
patients on admissions, administered antibiotics and its route, their dosages, dosing intervals, patients’
clinical diagnosis and indications for antibiotic use, Hospital-acquired infections (HAI) or Communityacquired
(CAI) and surgical antibiotic prophylaxis (SAP) or Medical antibiotics prophylaxis(MAP). Of
502 patients admitted in the hospital, 325(64.7%) received 1 Antimicrobial orders (AO) on the date of
the survey. Of 325 total AOs, 98 (30.2 %) were administered for (SAP) surgical prophylaxis, 19(5.84%) for
Medical prophylaxis, (MAP), 23(7%) for reasons not documented in the medical record, i.e., Unknown-
(UK), 167 (51.38%) were for CAI and 18(5.3%) for HAI. Parenteral Cefotaxim was the most prevalent
antibiotic generally used and for all types of infection onset category.51% of all prescriptions for CAI
was for respiratory infections. Broad spectrum AO treatment was prevalent, for both SAP and CAI
infections. Understanding common reasons for Antibiotic use (e.g., Lower respiratory infection) can help
focus education and stewardship efforts on areas in which improved use may have the greatest impact.
