Palliative Care Referrals in Cardiac Disease

With evidence of benefits of pediatric palliative care (PPC) integration, we sought to characterize subspecialty PPC referral patterns and end of life (EOL) care in pediatric advanced heart disease (AHD).

In this retrospective cohort study, we compared inpatient pediatric (<21 years) deaths due to AHD in 2 separate 3-year epochs: 2007-2009 (early) and 2015-2018 (late). Demographics, disease burden, medical interventions, mode of death, and hospital charges were evaluated for temporal changes and PPC influence.

Of 3409 early-epoch admissions, there were 110 deaths; the late epoch had 99 deaths in 4032 admissions. In the early epoch, 45 patients (1.3% admissions, 17% deaths) were referred for PPC, compared with 146 late-epoch patients (3.6% admissions, 58% deaths). Most deaths (186 [89%]) occurred in the cardiac ICU after discontinuation of life-sustaining therapy (138 [66%]). Medical therapies included ventilation (189 [90%]), inotropes (184 [88%]), cardiopulmonary resuscitation (68 [33%]), or mechanical circulatory support (67 [32%]), with no temporal difference observed. PPC involvement was associated with decreased mechanical circulatory support, ventilation, inotropes, or cardiopulmonary resuscitation at EOL, and children were more likely to be awake and be receiving enteral feeds. PPC involvement increased advance care planning, with lower hospital charges on day of death and 7 days before (respective differences $5058 [P = .02] and $25 634 [P = .02]).

Pediatric AHD deaths are associated with high medical intensity; however, children with PPC consultation experienced substantially less invasive interventions at EOL. Further study is warranted to explore these findings and how palliative care principles can be better integrated into care.
