Blood over-testing: impact, ethical issues and mitigating actions.

Area of Science:

• Clinical Medicine
• Laboratory Science
• Healthcare Management

Background:

• Hospital-acquired anemia (HAA) is linked to higher transfusion rates, mortality, and morbidity.
• Over-testing blood samples incurs significant patient, laboratory, and environmental costs.
• Current practices of frequent blood draws conflict with ethical principles like non-maleficence and patient autonomy.

Purpose of the Study:

• To highlight the negative consequences of hospital-acquired anemia and blood over-testing.
• To explore strategies for reducing unnecessary blood sample collection.
• To propose reducing blood draw volume as a viable alternative to reducing test frequency.

Main Methods:

• Review of existing literature on hospital-acquired anemia and blood over-testing.
• Analysis of the costs associated with excessive laboratory testing.
• Discussion of potential interventions, including nudge strategies and technological solutions.

Main Results:

• Hospital-acquired anemia increases patient burden, length of stay, and resource utilization.
• Blood over-testing wastes laboratory resources, impacts the environment, and delays testing for other patients.
• Reducing blood draw volume through methods like smaller tubes and automated platforms is feasible.

Conclusions:

• Implementing strategies to reduce blood draw volumes is a practical approach to mitigate the harms of HAA and over-testing.
• Technological, purchasing, and organizational adjustments can facilitate blood conservation in healthcare settings.
• This approach balances safety concerns with the need for efficient and ethical laboratory practices.
