How to save costs by reducing unnecessary testing: lean thinking in clinical practice.

Area of Science:

• Health economics
• Clinical diagnostics
• Healthcare management

Background:

• Rising healthcare expenditure poses a significant burden on national budgets.
• Routine diagnostic tests in hospitals often include unnecessary procedures.
• There is a need to control healthcare costs by optimizing diagnostic practices.

Purpose of the Study:

• To reduce healthcare expenditure by minimizing unnecessary diagnostic tests.
• To evaluate the impact of targeted interventions on diagnostic costs within a hospital department.

Main Methods:

• Diagnostic costs in the internal medicine department were analyzed from 2006-2008.
• Interventions included cost-awareness materials, feedback, mentorship, and protocol adherence.
• A 7.5% reduction in diagnostic expenditure was targeted for 2009.

Main Results:

• Total diagnostic costs decreased by 13% in 2009 compared to 2008.
• Expenditure on diagnostic tests reduced from 2.80 million euro to 2.45 million euro, saving 350,000 euro.
• The primary driver of cost reduction was a decrease in the number of laboratory tests performed.

Conclusions:

• Simple physician awareness interventions effectively reduced diagnostic costs.
• These cost-saving measures have the potential for broader application across hospitals and healthcare systems.
• Optimizing diagnostic test utilization is crucial for controlling national healthcare spending.
