About this study
Official title: A Retrospective Study on Personalized Dosing Strategy of Patients With Bacterial Infections Treated by Carbapenems From a Tertiary Medical Center During 2018-2021
Patients may benefit from the personalized carbapenem dosing strategy based on pharmacokinetics. The objective of this study is to retrospectively review and analyze the clinical outcomes of patients with different dosing strategy.
Read the detailed description
Rational use of carbapenem is closely associated with the clinical outcome of patients with infections. Serum concentration of carbapenem varies from different populations. The objective of this study is to describe the clinical outcome of patients with infection treated by carbapenem in China, regarding diagnosis, treatment and follow-up. It is a single-center, retrospective, descriptive study. Inclusion criteria are an age ≥ 18, diagnosed as bacteria infection and serum concentration must be determined during therapy. Data concerning clinical presentation, biological samples, treatment and follow-up will be assessed. A descriptive analysis will be performed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| CAR-R | Patients with impaired renal function (eGFR < 60ml/min/1.73m2) treated by carbapenem | |
| CAR-L | Patients with liver cirrhosis or impaired liver function (Child-Pugh grade B or C) treated by carbapenem | |
| CAR-LR | Patients with co-morbidity of both liver cirrhosis or impaired liver function (Child-Pugh grade B or C) and impaired renal function (eGFR < 60ml/min/1.73m2) treated by carbapenem | |
| CAR-N | Patients with normal liver function or renal function treated by carbapenem |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mortality
30-day mortality and 90-day mortality
Measured: January 2018-December 2021
Attainment of Target Trough Concentration
Attainment of Target Trough Concentration
Measured: January 2018-December 2021
Secondary outcomes (5)
Proportion of patients reach clinical response at end of treatment
By definition, a successful clinical response means resolution of clinically significant signs and symptoms(defined as any criteria of systemic inflammatory response syndrome, body temperature over 38℃ or below 36℃, blood white cell count more than 12*10^9/L or less than 4*10^9/L, respiratory rate faster than 20 times per minute and heart rate higher than 90 beats per minute) or partial resolution of clinically significant signs and symptoms
Measured: January 2018-December 2021
Proportion of patients reach clinical response at day 4 of treatment
By definition, a successful clinical response means resolution of clinically significant signs and symptoms(defined as any criteria of systemic inflammatory response syndrome, body temperature over 38℃ or below 36℃, blood white cell count more than 12*10^9/L or less than 4*10^9/L, respiratory rate faster than 20 times per minute and heart rate higher than 90 beats per minute) or partial resolution of clinically significant signs and symptoms
Measured: January 2018-December 2021
Daily Sequential Organ Failure Assessment score change
Sequential Organ Failure Assessment score (Range from 0-24), lower score means a better outcome. Increase of 2 points within 48 hours means the presence of sepsis.
Measured: January 2018-December 2021
Incidence of Septic Shock
Incidence of Septic Shock
Measured: January 2018-December 2021
Safety outcome measures
Safety outcome measures including nephrotoxicity, hepatotoxicity and other adverse events related to the antibiotic treatment of carbapenems
Measured: January 2018-December 2021
