End-of-life care decisions using Korean advance directives among cancer patient-caregiver dyads.

11 Background: The Korean advance directives (K-ADs) consist of a value statement, treatment directives (cardiopulmonary resuscitation [CPR], preferences for artificial ventilation, tube feeding, and hospice care). K-ADs can facilitate a patient's decision-making for end-of-life (EOL) care. This study aims to examine the extent to which patient-caregiver dyads agreed on decisions for EOL care using the K-ADs.


METHODS
Using a descriptive study design, 81 cancer patients were invited to participate. The final sample consisted of 44 patient-caregiver dyads who completed K-ADs; 36 (44.4%) of the initial 81 patients declined to participate.


RESULTS
Patient participants had different cancerdiagnoses: 29.5% colorectal cancer, 29.5% breast, and 15.9% liver/biliary tract cancers; 59% of the sample had advanced stage cancer. Spouse (70.5%) and adult children of the patient (20.4%) were primary caregivers with perceived bonding rated as fair (31.8%) or good (65.9%). Rejection of K-ADs was mainly because of difficulty in deciding EOL care (50%). Comfort in dying was the most common theme of the value statement for patients (73.8%) and caregivers (66.7%). For treatment directives, dyads advocated for hospice care (66.7%) and reduced support for aggressive treatments of CPR or artificial ventilation, k = .43, p = .004 and k = .28, p = .046, respectively. These approaches showed significantly mild to moderate concordance among the dyads. Sixteen out of the 21 dyads identified their spouses as a proxy, with others designating their adult children.


CONCLUSIONS
The findings of the study are exploratory but suggest the need for ongoing EOL discussion where patient-caregiver dyads are encouraged to participate in the decision-making for EOL care.
