Investigation of Queries Related to Antimicrobial Agents Use in a Tertiary Hospital from 2015 to 2018

Aim: This study compares factors associated with requests for antimicrobial agents versus those for other types of treatment, contrasting the requests of pharmacists versus those of other health-care staff related to antimicrobial agents. Methods: A retrospective cross-sectional study was conducted for all requests received from January 1, 2015, to December 31, 2018. A series of chi-squared tests was used to analyze the relationship between different categories. All data analyses were conducted using the R statistical computing language. Results: In total, 2,423 requests were received from 2015 to 2018, of which antimicrobial agents accounted for 21.67%. The highest percentages of antimicrobial requests by pharmacists were related to administration and dosage forms, pregnancy and lactation, and stability. A majority of the requests were answered using tertiary resources. The most-requested information regarding antimicrobial agents was related to clindamycin. Conclusion: Because many requests pertaining to antimicrobial agents were made, as a proportion of total drug and poison information centre requests, from 2015 to 2018, pharmacists should maintain and indeed expand their active role to combat antibiotic resistance.
