Bone Marrow Sampling and Transplants

490
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Area of Science:

  • Quality Improvement
  • Healthcare Management
  • Pediatric Oncology

Background:

  • Overuse of blood tests strains healthcare resources and poses risks like infection and anemia.
  • Pediatric cancer patients are especially vulnerable due to compromised immunity and limited blood volume.
  • Daily blood testing was a common practice, necessitating intervention.

Purpose of the Study:

  • To decrease the frequency of blood tests per bed day in an inpatient pediatric cancer unit by 15% within 8 months.
  • To implement a sustainable strategy for reducing unnecessary blood draws.

Main Methods:

  • A quality improvement project combined clinician education, collaborative guideline development, and behavioral change strategies.
  • Clinicians were encouraged to "STOP and THINK" about the necessity of each blood test.
  • Blood test frequency was compared before, during, and after the intervention from 2019-2021.

Main Results:

  • The intervention achieved a 37% overall reduction in blood tests within 8 months.
  • Liver Function Tests saw a significant 52% decrease in ordering frequency.
  • Data included 26,941 blood tests across 1,558 admissions.

Conclusions:

  • A multifaceted strategy integrating education and culture change effectively reduced blood test ordering frequency.
  • The implemented changes led to significant blood test reduction without evidence of increased patient harm.
  • This approach offers a model for optimizing diagnostic testing in vulnerable patient populations.
