要旨

Background:

Blinatumomab has transformed the treatment of pediatric B-acute lymphoblastic leukemia (B-ALL). However, it presents distinct operational challenges for administration given it is delivered as a continuous infusion and has unique toxicities. The objective of this project was to develop, implement, and evaluate a standardized institutional protocol for blinatumomab administration to optimize safety, efficiency, and patient experience.

Procedure:

This quality improvement (QI) initiative was conducted at The Hospital for Sick Children, Toronto, Canada. A multidisciplinary Blinatumomab Working Group developed harmonized standards across five domains: (1) caregiver education, (2) fever management, (3) nursing-led assessments, (4) infusion interruption management, and (5) use of 7-day infusion bags. Patients receiving blinatumomab for upfront therapy or for relapsed disease between July 2024 and August 2025 were included. Demographic and clinical data were extracted from the institutional data warehouse. Outcomes included rates of caregiver education completion, antibiotic use during blinatumomab initiation, and completion of nursing-led assessments.

Results:

Fifty-three patients received standard of care blinatumomab. All eligible caregivers (100%) completed standardized education. The rate of empiric antibiotic use during blinatumomab initiation decreased from 68% to 22% following adoption of selective antibiotic initiation without increased readmission, or prolonged stay. Nursing assessment completion was 95% for inpatients and 81% for outpatients. Infusion interruptions were managed using a standardized, risk-based algorithm without observed safety events.

Conclusion:

Implementation of multidisciplinary, standardized blinatumomab administration protocols was feasible and safe. These processes improved antibiotic stewardship, empowered nursing-led care, and reduced practice variability. This framework may inform best practices for the safe and efficient delivery of blinatumomab in other pediatric oncology centers.

Methods of Documentation V: CBE

Methods of Documentation V: CBE

Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

Quality Control

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Drug Control Governance: Regulatory Bodies and Their Impact

Drug Control Governance: Regulatory Bodies and Their Impact

Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with a...

Design Example: Aggregate Gradation

Design Example: Aggregate Gradation

The right type and quality of aggregates are crucial for concrete as they significantly influence its properties, mix proportions, and cost-effectiveness. If different sources are available for sand, the commonly used fine aggregate in concrete, the selection of sand is primarily based on its gradation.
The grading, or particle-size distribution, of sand is determined using sieve analysis, with standard sizes ranging from 150 μm to 10 mm (ASTM No. 100 sieve to 3⁄8 in. sieve). Sand is sampled...

Good Manufacturing Practices

Good Manufacturing Practices

Good Manufacturing Practices (GMP) constitute a foundational set of guidelines that ensure the production of safe, consistent, and high-quality products, particularly in industries such as pharmaceuticals, biotechnology, and food processing. These protocols encompass all aspects of production, from the sourcing of raw materials to the final distribution of the finished product.A core pillar of GMP is stringent hygiene and sanitation across all production environments. This includes routine...

Hazard Analysis and Critical Control Points (HACCP)

Hazard Analysis and Critical Control Points (HACCP) is a science-based, preventive system used globally to ensure food safety by identifying, evaluating, and controlling biological, chemical, and physical hazards throughout food production. Originally developed by NASA and the Pillsbury Company for astronaut food, HACCP is now a core component of the Codex Alimentarius.HACCP operates on prerequisite programs—such as Good Manufacturing Practices (GMPs), sanitation procedures, and supplier...
