Abstract
Aim:
To examine the intensity of care at the end of life among older adults in Korea and to identify the individual and institutional factors associated with care intensity.
Methods:
This secondary data analysis included a sample of 6278 decedents aged 65 years or older who were identified from the 2009 to 2010 Korean National Health Insurance Service–National Sample Cohort Claims data. We examined the medical care received by the cohort in the last 30 days of their lives.
Results:
Overall, 36.5% of the sample received at least 1 intensive care procedure in the last 30 days of their lives; 26.3% of patients experienced intensive care unit admission, with an average stay of 7.45 days, 19.5% received mechanical ventilation, 12.3% received cardiopulmonary resuscitation, and 15.5% had a feeding tube placement. A statistical analysis using a multiple logistic regression model with random effects showed that younger age, higher household income, primary diagnoses of diseases (ischemic heart disease, infectious disease, chronic lung disease, or chronic heart disease), and characteristics of care setting (large hospitals and facilities located in metropolitan areas) were significantly associated with the likelihood of receiving high-intensity care at the end of life.
Conclusion:
A substantial number of older adults in Korea experienced high-intensity end-of-life care. Both individual and institutional factors were associated with the likelihood of receiving high-intensity care. Gaining an understanding of the intensity of care at the end of life and the impact of the determinants would advance efforts to improve quality of care at the end of life for older adults in Korea.
