Background
As per WHO(2019), Antimicrobial resistance (AMR) is one of the top ten global public health threats facing humanity. Surveillance systems (Point Prevalence Study) are the cornerstones of successful implementation of sustainable antimicrobial stewardship programs and thus reduce AMR. This study was conducted to observe the antimicrobial consumption practices .
Objectives
The objectives of the PPS study were to estimate the prevalence of antibiotic use, most commonly prescribed antimicrobials, assess antibiotic usage as per AWaRe classification
Methods
A cross sectional PPS (on a single day in December 2021) was conducted in a tertiary care hospital with prior ethical approval. All admitted patients in the ICU/wards receiving at least one antimicrobial admitted before 9.00 am on the day of data collection were included . Data was collected using two structured case record forms: ward level and patient level data.The outcome measures were analyzed & represented in percentages.
Results
278 patients with antibiotic prescriptions were surveyed & total antimicrobials prescribed were 429. Prescriptions with a single antibiotic are 55.1% (145 ), two antibiotics are 32.8 % (118), ≥ 3 antibiotics are 12.1% (15). As per WHO AWaRe classification , 43.5 % (187) were of Access,55.4 %(238) of Watch & 0.1% (4) of Reserve category. Community acquired infection (38. 5%) followed by Surgical prophylaxis (28.4 %) was the most common diagnosis . 8.6 % (24) & 16.5 % (46) patients were receiving double anaerobic cover & double gram negative cover respectively . Most commonly used antimicrobials was Metranidazole (21.44 %) followed by Ceftriaxone (19.11 %).
Conclusion: To preserve the future effectiveness of antibiotics , it is imperative to rationally scrutinize and improve prescribing practices. This PPS survey would be helpful in generating baseline data for identifying strategies directed at reducing antimicrobial use & to develop evidence based antimicrobial prescribing guidelines.
