Clinical pharmacists' involvement in carbapenem antibiotics management at Wenzhou Integrated Hospital.

BACKGROUND

Carbapenem antibiotics are a pivotal solution for severe infections, particularly in hospital settings. The emergence of carbapenem-resistant bacteria owing to the irrational and extensive use of carbapenems underscores the need for meticulous management and rational use. Clinical pharmacists, with their specialized training and extensive knowledge, play a substantial role in ensuring the judicious use of carbapenem. This study aimed to elucidate the patterns of carbapenem use and shed light on the integral role played by clinical pharmacists in managing and promoting the rational use of carbapenem antibiotics at Wenzhou Integrated Traditional Chinese and Western Medicine Hospital.

AIM

To analyze carbapenem use patterns in our hospital and role of clinical pharmacists in managing and promoting their rational use.

METHODS

We performed a retrospective analysis of carbapenem use at our hospital between January 2019 and December 2021. Several key indicators, including the drug utilization index, defined daily doses (DDDs), proportion of antimicrobial drug costs to total hospitalization expenses, antibiotic utilization density, and utilization rates in different clinical departments were comprehensively analyzed.

RESULTS

Between 2019 and 2021, there was a consistent decline in the consumption and sales of imipenem-cilastatin sodium, meropenem (0.3 g), and meropenem (0.5 g). Conversely, the DDDs of imipenem-cilastatin sodium for injection increased in 2020 and 2021 2019, with a B/A value of 0.67, indicating a relatively higher drug cost. The DDDs of meropenem for injection (0.3 g) exhibited an overall upward trend, indicating an increasing clinical preference. However, the B/A values for 2020 and 2021 were both > 1, suggesting a relatively lower drug cost. The DDDs of meropenem for injection (0.5 g) demonstrated a progressive increase annually and consistently ranked first, indicating a high clinical preference with a B/A value of 1, signifying good alignment between economic and social benefits.

CONCLUSION

Carbapenem use in our hospital was generally reasonable with a downward trend in consumption and sales over time. Clinical pharmacists play a pivotal role in promoting appropriate use of carbapenems.
