Cost comparison between the atraumatic and cutting lumbar puncture needles

Area of Science:

• Health Economics
• Medical Devices

Background:

• Diagnostic lumbar puncture is a common procedure.
• Post-lumbar puncture headache (PLPH) can increase healthcare costs due to treatment needs.
• Spinal needle design may influence procedure costs and patient outcomes.

Purpose of the Study:

• To compare the cost-effectiveness of atraumatic versus cutting spinal needles for diagnostic lumbar puncture.
• To evaluate the economic impact of needle choice on healthcare expenditures, including PLPH treatment.

Main Methods:

• A decision-analytic model was employed to assess costs from a healthcare system perspective.
• Probabilities for patient events were derived from existing literature.
• Economic outcomes were measured by cost differences between needle types, with sensitivity analyses performed.

Main Results:

• The atraumatic needle resulted in average cost savings of $26.07 per patient compared to the cutting needle.
• Total healthcare costs were $166.08 with the atraumatic needle versus $192.15 with the cutting needle.
• Probabilistic sensitivity analysis indicated a 94% certainty that the atraumatic needle is more cost-saving.

Conclusions:

• The atraumatic spinal needle is associated with overall cost savings for the US healthcare system.
• The use of atraumatic needles over cutting needles for diagnostic lumbar puncture is favored due to a better balance of costs and benefits.
