Antibiotic Dosing in Geriatric Patients At the Emergency Department
Sponsor: University Hospital, Ghent
Summary
In this pilot study, we will investigate whether - with the current dosing regimens, used in the Ghent University Hospital - pharmacodynamic targets regarding beta-lactam antibiotics (more specific Amoxicilline-Clavulanate, Piperacillin-Tazobactam and Temocillin) are attained in frail patients admitted to the geriatric department.

Interventions
Blood sampling
At predefined time points through a venous catheter already in place. Max. volume to be withdrawn: Maximum 4ml/sample. Maximum 10 samples/patient. A last blood sample will be taken, if necessary, after the end of antibiotic therapy, between day 7 and day 14. Though blood results preferably will be used from available data from tests already done during standard treatment. Samples are collected in lithium-heparin tubes (without gel) and centrifuged immediately (within a maximum of 30 minutes after sampling) at room temperature: 8 minutes at 1885g. Plasma is then collected and divided in two separated labelled Eppendorf tubes 1.5 ml and immediately frozen at - 80 °C. If this is not immediately possible, tubes are frozen at - 20 °C and at regular time points transferred to a freezer at - 80 °C (minimum twice a day).
Sputum sample
Bacteriological specimen, such as blood cultures, urine samples, sputum ea., which are usually collected in every patient according to standard care will be retained. If there is bacterial growth, MIC's will be calculated on these strains for study purpose.
Hemoculture
Bacteriological specimen, such as blood cultures, urine samples, sputum ea., which are usually collected in every patient according to standard care will be retained. If there is bacterial growth, MIC's will be calculated on these strains for study purpose.
Urine sample
Bacteriological specimen, such as blood cultures, urine samples, sputum ea., which are usually collected in every patient according to standard care will be retained. If there is bacterial growth, MIC's will be calculated on these strains for study purpose.
