Conditions: Leukemia Lymphoma Blood Disorders Solid Tumors
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 30
Healthy volunteers: no

Brief summary:
The study team will compare hospital length of stay (LOS) and attributable length of stay (ALOS, the LOS attributable to CRI), in a randomized, un-blinded prospective trial utilizing short-dwell ethanol-lock therapy (ELT) (4 hours to 24 hour dwell times per day, repeated for up to 72 hours) placed within 24 - 36 hours of admission(Group 1, Preemptive ELT) versus ELT placed at the time of first positive blood culture report (Group 2, Rescue ELT (Standard of Care ). ELT will be given in both groups, in combination with systemic antibiotics, for the treatment of CRI (suspected or proven) of the blood in children with central catheters. Participants will be enrolled from patients with hematologic/oncologic disorders and bone marrow or hematopoetic stem cell transplants (BMT) admitted for care to Children's Hospital of Michigan (CHM), a tertiary care pediatric hospital in Detroit, Michigan. ALOS will be defined as the number of hospital days between first symptoms of Catheter-related infection (CRI) (or date of admission for those admitted with symptoms) and first negative blood culture.

Study Hypothesis: The main hypothesis is that the short-dwell ethanol-lock therapy, defined above, placed within 24 - 36 hours of symptoms/admission (Arm 1) versus ELT placement at the time of first positive blood culture report (Arm 2), with concomitant systemic antibiotics, for the treatment of CRI (suspected or proven) of the blood in children with central catheters in the H/O/BMT population will have shorter hospital length of stay (LOS) and attributable LOS (ALOS) and therefore lower hospital costs.

Detailed description:

ELT will be given in both groups, in combination with systemic antibiotics, for the treatment of Catheter-related Infection (CRI) (suspected or proven) of the blood in children with central catheters. Participants will be enrolled from patients with hematologic/oncologic disorders and bone marrow or hematopoetic stem cell transplants admitted for care to Children's Hospital of Michigan (CHM), a tertiary care pediatric hospital in Detroit, Michigan. ALOS will be defined as the number of hospital days between first symptoms of CRI (or date of admission for those admitted with symptoms) and first negative blood culture.

Aim 1: Compare two different treatment regimens for CRI using ELT (the preemptive ELT vs. standard of care) by way of a prospective, randomized, two-arm study.

Study Hypothesis: The main hypothesis is that the short-dwell ethanol-lock therapy, defined above, placed within 24 - 36 hours of symptoms/admission (Arm 1) versus ELT placement at the time of first positive blood culture report (Arm 2), with concomitant systemic antibiotics, for the treatment of CRI (suspected or proven) of the blood in children with central catheters in the H/O/BMT population will have shorter hospital length of stay (LOS) and attributable LOS (ALOS) and therefore lower hospital costs.

Aim 2: Compare sterilization rate of the infected intravascular device after ethanol-lock therapy (as defined by a negative blood culture obtained from the infected catheter 24 - 72 hours after ELT) and central catheter salvage rate after CRI using ELT in the two study arms. If the central catheter is salvaged for further clinical use, recurrence of infection with the same organism (re-infection) of the central catheter for 28 days from date of first ELT procedure will also be assessed.

Aim 3: Assess tolerability and adverse effects of the ELT (safety).

Aim 4: Perform sub-group analysis on the BSI episodes meeting National Healthcare Safety Network (NHSN) criteria for laboratory confirmed central line associated BSI (CLABSI) into the three categories of Criteria 1, 2 or 3 within the pediatric

Arms:
arm 1: Participants receive ethanol lock before blood cultures grow germ arm 2: Participants receive ethanol lock if and only after blood cultures grow germ

Interventions: intervention 1: Ethanol lock therapy (ELT)
Intervention descriptions: intervention 1: Participants will be randomized to receive early (preemptive) ELT (after 12 hours from time blood culture drawn, but before blood culture positive, R/O sepsis) with systemic antimicrobials versus standard ELT (placed in catheter when blood culture is positive for growth of a germ) with systemic antimicrobials.
