Insights
The Decisions on Life-Sustaining Treatment Act did not reduce medical costs. Patients who chose to forgo life-sustaining treatment incurred higher healthcare expenses, contrary to expectations.
Area of Science:
- Medical Economics
- Healthcare Policy
- End-of-Life Care
Background:
- The Decisions on Life-Sustaining Treatment Act aimed to respect patient autonomy in end-of-life care.
- Previous assumptions suggested that withholding or withdrawing life-sustaining treatment might reduce medical costs.
Purpose of the Study:
- To analyze the impact of the Decisions on Life-Sustaining Treatment Act on medical costs.
- To investigate whether patients undergoing decisions on life-sustaining treatment incur fewer healthcare expenses.
Main Methods:
- Analysis of medical cost data from the National Health Insurance Service-National Sample Cohort.
- Identification of patients who died in 2018-2019.
- Propensity score matching to create case (implemented life-sustaining treatment) and control groups.
Main Results:
- The case group (with life-sustaining treatment) exhibited higher medical costs across all periods before death.
- Significant cost differences were observed in consultation, admission, injection, laboratory tests, imaging and radiation therapy, nursing hospital bundled payments, and special equipment.
Conclusions:
- This study is the first cost analysis examining the impact of the Decisions on Life-Sustaining Treatment Act.
- The findings challenge the common expectation that decisions to withhold or withdraw life-sustaining treatment lead to reduced medical costs.
Abstract:
This study measured the impact of the Decisions on Life-Sustaining Treatment Act by analyzing medical cost data from the National Health Insurance Service-National Sample Cohort. After identifying the patients who died in 2018 and 2019, the case and control groups were set using the presence of codes for managing the implementation of life-sustaining treatment with propensity score matching. Regarding medical costs, the case group had higher medical costs for all periods before death. The subdivided items of medical costs with significant differences were as follows: consultation, admission, injection, laboratory tests, imaging and radiation therapy, nursing hospital bundled payment, and special equipment. This study is the first analysis carried out to measure the impact of the Decision on Life-Sustaining Treatment Act through a cost analysis and to refute the common expectation that patients who decided to withhold or withdraw life-sustaining treatment would go through fewer unnecessary tests or treatments.
