Insights
Withdrawing pulmonary artery catheters (PACs) from UK intensive care units (ICUs) is cost-effective. This study found significant savings per Quality-Adjusted Life Year (QALY) and life gained, informing healthcare decisions.
Area of Science:
- Health Economics
- Critical Care Medicine
- Clinical Decision Making
Background:
- Pulmonary artery catheters (PACs) are an established intervention in UK intensive care units (ICUs).
- The cost-effectiveness of PACs in routine clinical practice requires ongoing evaluation to inform healthcare resource allocation.
- Understanding the economic implications of established medical technologies is crucial for National Health Service (NHS) decision-makers.
Purpose of the Study:
- To conduct an economic evaluation comparing costs and outcomes of patients treated with and without PACs.
- To provide data to healthcare decision-makers regarding the use of PACs in ICUs.
- To assess the cost-effectiveness of withdrawing PACs from routine use.
Main Methods:
- Economic evaluation conducted alongside a UK clinical trial.
- Perspective of the UK National Health Service (NHS).
- Primary outcome: Quality-Adjusted Life Years (QALYs). Secondary outcome: hospital mortality. Costs calculated for 2002/03. Bootstrap methods used for uncertainty analysis and cost-effectiveness acceptability curves.
Main Results:
- The cost per QALY gained from withdrawing PACs was £2892.
- The cost per life gained from withdrawing PACs was £21,164.
- These figures suggest a favorable economic return upon discontinuation of PAC use.
Conclusions:
- Withdrawal of PACs from routine clinical use in UK ICUs is considered cost-effective.
- The findings support a shift in clinical practice towards non-PAC treatment strategies.
- This economic evaluation provides evidence for optimizing resource allocation within the NHS.
Objective:
The objective of this study was to conduct an economic evaluation to identify any differences in the expected costs and outcomes between patients treated with pulmonary artery catheters (PACs) and those without, in order to better inform healthcare decision makers.
Method:
The evaluation was carried out alongside a clinical trial investigating the use of PACs in intensive care units (ICUs) in the UK. It was conducted from the perspective of the UK NHS, in which PACs are an established intervention. Treating patients without using a PAC was characterised as the new intervention. The primary outcome measure was QALYs. The secondary outcome measure was hospital mortality. NHS costs per patient were calculated for the financial year 2002/03. The bootstrap method was used to characterise the uncertainty of the results and to construct cost-effectiveness acceptability curves.
Results:
The cost per QALY and per life gained from the withdrawal of PACs were Pounds 2892 and Pounds 21,164, respectively.
Conclusion:
The results of this study indicate that withdrawal of PACs from routine clinical use in ICUs within the NHS would be considered cost effective in the current decision-making climate.
