Abstract

Aim: The 2018 life-sustaining treatment (LST) decision law is expected to improve end-of-life quality in Korea. This study evaluated the national effect of the LST decision law on the cardiopulmonary resuscitation (CPR) rate among pediatric patients who died during hospital admission.

Methods: This retrospective cohort study was based on the Korean National Health Insurance database. Pediatric admissions within 12 months before or after implementation of the LST decision law were compared, allowing a 1-month transition period (February 2018). The changes in mortality, CPR, and documentation of LST decision were evaluated.

Results: The CPR rate of patients who died in hospital decreased after establishment of the LST decision law (49.6 vs 43.4 %, P = 0.04), without change of in-hospital mortality between pre/post-LST decision law activation (0.83 vs 0.81 per 1000 admissions, P = 0.67). In addition, in-hospital CPR (0.73 vs 0.67 per 1000 admissions, P = 0.15) and survival to discharge after in-hospital CPR (43.6 vs 47.2 %, P = 0.27) were slightly improved, although there was no statistical significance. Patients with LST decision documentation were less frequently mechanically ventilated (69.8 % vs 80.4 %, P < 0.01) and used fewer inotropes (76.5 % vs 90.1 %, P < 0.01) and more frequent opioids (67.1 % vs 57.4 %, P = 0.04).

Conclusions: The legally guided process of LST decision can decrease the CPR rate of children who die in hospitals. This result highlights the possibility of improving end-of-life quality by reducing non-beneficial in-hospital CPR.
