Description of intervention(s) / exposure
1. Assessment of pharmacokinetic/pharmacodynamic outcomes of beta lactam antibiotics which are prescribed in the course of standard care of neutropenic fever. Specifically, two drug levels will be collected in steady-state to calculate the time during the dosing interval for which the unbound antibiotic concentration remains above the desired MIC.
2. Assessment of clinical outcomes, including rate of resolution of infection, duration of antibiotic treatment, length of hospital stay, overall survival. The maximum period of observation will be 30 days.
3. Assessment of changes in creatinine clearance with the onset of sepsis, using timed urine collection before and after onset of fever.

Outcomes
Primary outcome [1] 295660 0
The achievement of target serum beta-lactam concentrations as measured by the time during the dosing interval for which the unbound antibiotic concentration remains above the desired minimum inhibitory concentration (fTMIC).
Timepoint [1] 295660 0
Two samples collected in steady state (ie at least 24 hours after commencing antibiotic): one at mid-dosing interval and one at end of dosing interval.
Secondary outcome [1] 316137 0
Creatinine clearance at baseline and following the onset of sepsis, calculated using paired serum and 24 hour urine samples.
Timepoint [1] 316137 0
At enrolment and again at onset of first fever.
Secondary outcome [2] 316850 0
Time to resolution of infection, defined by time to normalisation of temperature and haemodynamic parameters. This information will be collected from the patient's hospital record.
Timepoint [2] 316850 0
Days from time of first fever. This information will be collected from the patient's hospital record.
Secondary outcome [3] 316851 0
Duration of antibiotic treatment. This information will be collected from the patient's hospital record.
Timepoint [3] 316851 0
Days from time of initiation of antibiotic. This information will be collected from the patient's hospital record.
Secondary outcome [4] 316852 0
Duration of in-patient hospital stay. This information will be collected from the patient's hospital record.
Timepoint [4] 316852 0
Days from time of first fever to discharge. This information will be collected from the patient's hospital record.
Secondary outcome [5] 316853 0
Overall survival. This information will be collected from the patient's hospital record.
Timepoint [5] 316853 0
30 days from time of first fever. This information will be collected from the patient's hospital record.

Summary
Brief summary
The primary purpose of this study is to evaluate the pharmacokinetic and pharmacodynamic outcomes with standard beta lactam antibiotics given to patients with febrile neutropenia as a result of intensive chemotherapy. Who is it for? You may be eligible to join this study if you are aged 18 or over, and have been prescribed a course of intensive chemotherapy for acute leukaemia or high-grade lymphoma. Study details This is an observational study, so all participants will undergo the standard care prescribed to them by their treating physician. To assess outcomes, blood samples will be taken at baseline, two samples approximately 24 hours after commencement of antibiotics and at onset of fever, and one urine sample will also be taken 24 hours after onset of fever. Additional information including length of antibiotic use and hospital stay will also be noted. It is hoped that the findings of this trial will aid understanding of the distribution and levels of this class of antibiotics in the body, and their impact on outcomes in patients with febrile neutropenia as a result of intensive chemotherapy.
