  2. Outline • Introduction • Pediatric death • “A Good Death” • Palliative Care defined • Case 1: Isaiah • Prenatal and pre-operative counseling • Medical education • Case 2: Sara • Healthcare costs • Compassion fatigue • Case 3: Ethan • Parental perceptions

  3. Introduction • ~54,000 children die annually in the US. • ~7 million children worldwide could benefit from palliative care; 5000-8600 per day in US! • Infant mortality rate in US = ~7 per 1000 live births. • Death rate among children <1yo is higher than that in any other pediatric age group. • Most common etiology is congenital heart disease (CHD). • Most children die in the hospital, particularly the ICU. • >90% of these spend their entire life in the hospital.

  4. A “good” death? • “A decent or good death is one that is: free from avoidable distress and suffering for patients, families, and caregivers; in general accord with patients’ and families’ wishes; and reasonably consistent with clinical, cultural, and ethical standards.” Institute of Medicine. Approaching Death: Improving Care at the End of Life. 1997. • “Death is rarely good, but a constellation of factors add up to a better death.” Gazelle G. A good death: Not just an abstract concept. J of Clin Onc. 2003. • “A good death is hard to define, however, for a good death is as complex as the good life of which it is an extension.” Kahn D, Steeves R. Narrative of dying aimed at understanding a ‘good death.’ Textbook of Palliative Nursing. 2001.

  5. WHO Definition of PPC • “…aims to improve the quality of life of patients facing life-threatening illness, and their families, through the prevention and relief of suffering by early identification and treatment of pain and other problems, whether physical, psychosocial, or spiritual.” • Total care of child’s mind, body, spirit + family support. • Begins when illness is diagnosed, and continues irrespective of whether or not child receives disease-directed treatment. • Emphasis on alleviating child’s physical, psychological and social distress. • Broad multidisciplinary approach including family and available community resources. • Can be provided in tertiary-care facilities, community health centers, home.

  6. PPC in the CVICU • Prenatal diagnosis • ~75% of all hypoplastic left heart syndrome (HLHS) cases diagnosed prenatally. Atz et al. JTCVS. 2010. • Curative vs. palliative surgery; multiple operations. • Promising short-term survival vs. uncertain long-term prognosis. • Considerable variation in mortality and morbidity among institutions. • Cardiac transplantation. • High medical costs. • Surgical vs. medical management philosophies.

  7. Case 1 • Isaiah’s African-American parents presented to an outside ER intoxicated. Mom was in labor and had had limited prenatal care during her pregnancy. • Mom is 25 years old; this is her 4th living child and 6th pregnancy. She admitted to marijuana use during pregnancy. Dad is 19 years old, lives with GM. • Delivery was reportedly uncomplicated but the infant’s BAL was 0.17. He had facies characteristic of fetal alcohol syndrome. Birth weight was 2.0 kg. • Within the first 24 hrs of life, the infant developed respiratory distress and cyanosis. He was intubated. • At AHMC NICU, a diagnosis of HLHS was made. Prostaglandin infusion was started.

  8. Hypoplastic Left Heart Syndrome

  9. Surgical Options for HLHS- Stg 1 Norwood Operation with modified BT shunt (or Sano Modification) Hybrid Stage 1- PDA stent, bilateral PA bands, atrial septostomy

  10. Diagnosis List • Hypoplastic Left Heart Syndrome • Severe tricuspid regurgitation • Fetal Alcohol Syndrome • Small for gestational age • Eventration of right diaphragm • Hypoplastic right lung (20-25% decreased volume) • Bilateral cryptorchidism • Parental alcohol addiction • Possible FAS in siblings • Poor social situation • Other family members/caretakers with alcoholism

  11. Case 1 • NICU/Cardiology teams face massive denial from mother regarding diagnoses. • Isaiah is stable but requiring increasing ventilator support. • Staffing is arranged on DOL 11. • Mother is intoxicated in court the day prior and is subsequently hospitalized for substance abuse. • Custody of other 3 children given to MGM; parents retain medical decision-making rights. • Staffing is held with NICU and Cardiology teams, nursing and Dad.

  12. Treatment options for HLHS • Palliative surgery (Norwood vs. hybrid stage I, Stage II- Glenn vs. hemi-Fontan, Stage III- Fontan). • 5-yr survival = 38-72%. • Cardiac transplantation • 5-yr survival = 55-76%; however, if waitlist mortality is included, survival = 54%. • Palliative care* Fontan Bidirectional Glenn

  13. Palliative Care for HLHS • 2008 data from England, Australia: • Similar surgical outcomes as US. • Parents counseled about availability of PPC; surgery is recommended. • Termination of pregnancy after prenatal dx of HLHS: ~20% of cases in US. - Allen et al. J Ultrasound Med, 2005. • Doctrine of informed consent: • 1. Recommended treatment option, • 2. All reasonable alternatives, • 3. Consequences of not choosing life-prolonging therapy.

  14. The PPC Debate • Con: • Outcomes for HLHS surgery are good, and similar to those for other CHD and critical pediatric illnesses. • Therefore, palliative care is not an acceptable alternative and should not be offered. • Pro: • As many parents and physicians would choose palliative care, it is a reasonable option regardless of surgical outcomes. • Many factors other than survival sway parental decisions. • No outcome statistic can override the reasonable person standard; therefore, palliative care is a reasonable treatment option.

  15. Parental Counseling for HLHS Prsa et al, Pediatrics, 2010: Survey of 749 pediatric cardiologists and surgeons. • When counseling parents of newborns with HLHS, • 99.7% discussed staged palliative surgery, • 67% discussed cardiac transplantation, • 62.2% discussed compassionate care without surgery. • Only 14.9% discussed all options; 76.2% recommended surgery over other options. • When counseling parents after prenatal dx of HLHS, • 98.8% discussed continuation of pregnancy + palliative surgery, • 53.5% discussed continuation of pregnancy + cardiac transplantation, • 56.9% discussed continuation of pregnancy + palliative care, • 74.3% discussed termination of pregnancy. • 36.5% discussed all options; 56% recommended surgery over other options.

  16. What would YOU do? • Prsa et al. Pediatrics, 2010. • Post-natal dx of HLHS: • Staged palliative surgery= 42% • Cardiac transplantation= 2% • Palliative care= 19% • Prenatal dx of HLHS: • Continuation of pregnancy + surgery= 24% • Continuation of pregnancy + transplantation= <1% • Termination of pregnancy or continuation or pregnancy + palliative care= 47%. • Kon et al. Am J of Cardiol, 2003: 215 neonatologists, intensivists, cardiologists, surgeons. • Post-natal dx: 32%- surgery, 6%- transplant/bridge to transplant, 28% palliative care. • Prenatal dx: 22%- continue pregnancy, 48%- termination. • ~55% of parents of HLHS children opt for palliative care when presented with all treatment options.* (*Data from 2000, 2001).

  17. Case 1 • Given choice of palliative care vs. Norwood operation, dad chose surgery. • On DOL 16, Isaiah had long and complicated operation but was able to separate from cardiopulmonary bypass for ~2hrs. • During diaphragm repair, he developed pulmonary hemorrhage, severe ventilatory difficulty, hypoxia. • After 2-3 hours of consideration, decision made to transition to ECMO.

  18. Extracorporeal Membrane Oxygenation

  19. Case 1 • Returned to PSHU coagulopathic, anuric. • ECMO flow limited by small cannula size. • Dad present at bedside daily. Mom present since POD #1. • On POD #3, PRISMA initiated. • Disagreement among healthcare staff. • Mom initially did not want to continue. • Ultimately chose PRISMA x 48hrs.

  20. Case 1 • Later that day, worsening lactic acidosis, progressive coagulopathy, capillary leak, shedding of bowel mucosa, GI bleeding. • Head US shows early evidence of ischemic injury; patient has not woken up since OR. • Lactate>14 all night.

  21. Case 1 • Parents independently feel like Isaiah is suffering, dying, that “it was time.” • Deny offers for family support, chaplain. • Request immediate withdrawal of support. • Father holds baby while supported on ECMO and extubated. • Isaiah is placed on bed, circuit clamped. Expires peacefully 15 minutes later with parents holding his hands.

  22. Palliative Care Education • Hilden et al. J Clin Oncol, 2001: 228 pediatric oncologists in USA, Canada, UK • 92% learned PPC through ‘trial and error.’ • 38% had associated traumatic experience with pt. • 1970s: 6% of medical schools incorporated palliative care in curriculum; 1990s: 30% (mostly pre-clinical or elective). • Typical 1st exposure is during residency. • Regardless of level, method, or type of educational intervention or evaluation, improvement is seen in outcome measures. • Barriers to PPC education = lack of time, lack of knowledgeable faculty and mentors. • Jan 2010: 74 active palliative care fellowships. • Role for specially trained, board-certified palliative care NPs.

  23. Case 2 • Sara is a 4mo female infant with prenatally suspected chromosomal trisomy and unbalanced AV septal defect. • Mom is 39yo, dad is 42yo; middle-class, Hispanic, Catholic. • Due to religious beliefs, they choose to continue pregnancy to term. • Upon delivery, she is diagnosed with trisomy 21 (Down Syndrome), UAVSD (R-dominant), coarctation of aorta. Parents request full medical and surgical treatment.

  24. Unbalanced atrioventricular septal defect

  25. Diagnosis List • Unbalanced AV septal defect • Right-ventricle dominant • Bilateral superior venae cavae • Single ventricle • Coarctation of the aorta • Trisomy 21 (Down Syndrome) • Bilateral clubbed feet • Cystic right kidney • Tracheomalacia

  26. Case 2 • Sara undergoes neonatal coarctation repair, followed by pulmonary artery band placement a month later. • She is discharged home where she grows, develops and returns at age 4 months for her bilateral bidirectional Glenn and Damus-Kaye-Stansel operations. • Her operative course is complicated by 3 CPB runs for hypoxemia, bradycardia, ventricular dysfunction. • She is returned to the PSHU with an open sternum with snares in place for possible ECMO cannulation.

  27. Case 2 • Cardiac arrest, followed by E-CPR ensues. Sara develops severe capillary leak; Glenn pressures are noted to be elevated. • Serial head US demonstrate evidence of hypoxic ischemic injury. • 10 days after initial surgery, she undergoes takedown of her Glenn and placement of central shunt. She is taken off ECMO successfully. • She remains an ECMO candidate. • Parents kept updated regularly and continue to request full support.

  28. Case 2 • Sara’s condition continues to deteriorate over the next month with: capillary leak, arrhythmia, thrombocytopenia, copious chest tube output (despite thoracic duct ligation and chemical pleurodesis), diastolic dysfunction, kidney failure. • She has another brief cardiac arrest. Head US demonstrates evolving global ischemic injury. • Parents are informed of her grim condition but struggle with their choices. She remains full code. • The medical team decides that she is no longer an ECMO candidate.

  29. Economic$ of $ingle ventricle $urgery • Between 1998-2007, cumulative median length of stay, costs and charges for 3-stage palliative surgery: • LOS: 44 days • Costs: $171,672 • Charges: $376,403 • Increasing costs thought to be due to increasing survival: 57%82%. • Cardiac transplantation associated with highest resource utilization and costs. • Highest cost for palliative surgery followed by transplantation. • 26-36% likelihood of death or transplantation following stage I surgery. • Costs comparable to other major congenital malformations, prematurity…? • Appropriateness of use of limited societal resources.

  30. Dean et al. Pediatrics, 2011

  31. Case 2 • Sara has 4 cardiac arrests in 24 hours, many more over following month. • Massive work-up initiated: EEG, head/abd US, specialized blood tests. • Dialysis is started and poorly tolerated. • Anasarca worsens. Tremendous skin breakdown with weeping and blisters occurs. • Medical staff struggles with caring for infant because of difficulty with pain control. • Parents want Sara to “make the decision.” Somewhat mixed messages from medical team. She remains full code.

  32. Case 2 • “What are we doing?” • Sara becomes septic. She has cardiac arrests nearly every day, many of which are witnessed by her family. • Inotropic support is drastically escalated. • During her final cardiac arrest, MD suggests that mom hold her. She passes away. • Parents seem stunned, distraught. • Medical staff are supportive but drained.

  33. Compassion Fatigue • Described in 1992 when studying burnout in ER nurses: “A unique form of burnout that affects people in caregiving professions.” • Sx: Fatigue, avoidance, depression, overeating, headaches, bodyaches, cynicism, boredom, loss of compassion, poor communication, more sick days, decreased productivity. • Aggravated by high workloads, staff shortages. • Disenfranchised grief; ongoing fluctuation between focusing on loss (experiencing grief) or repressing it (avoidance). • Need for greater support for healthcare professionals.

  34. Case 3 • Ethan is a Caucasian male neonate with prenatally diagnosed HLHS. • Post-natally, he is noted to have multiple congenital anomalies. • 32yo mother, 38yo father, 5yo sister, 17yo step-brother. Middle-class, employed. • Palliative care never offered. • Stage I surgery performed on DOL 11.

  35. Diagnosis List • Hypoplastic left heart syndrome • Coffin-Siris syndrome • Absent corpus callosum, coprocephaly. • Abnormal gut anatomy, delayed gastric emptying, pyloric hypertrophy • Unilateral choanal atresia

  36. Case 3 • First extubation attempt occurs 3 weeks post-op followed by multiple failed attempts and 3 cardiac arrests over next 3 mos. • He is treated for necrotizing enterocolitis, has significant feeding difficulties, undergoes gastrostomy, jejunostomy. • Successfully extubated 3 mos after initial surgery. • Over next 2 mos, has more feeding difficulties, failure to thrive.

  37. Case 3 • At 6 mos age, 3.5-kg, undergoes bidirectional Glenn, TV plasty. • Fails extubation repeatedly. Has multiple cardiac arrests. • Develops junctional rhythm requiring atrial pacing via temporary pacing wires, which he pulls out. • Access is difficult because of vessel occlusion; however, indwelling catheters have to be removed because of infections. • Undergoes Nissen, pyloroplasty at 7 mos. • Ethan’s R diaphragm is plicated; new invasive lines are placed.

  38. Case 3 • Ethan tolerates feeds but fails to gain weight. • He fails extubation repeatedly; bronchoscopy demonstrates airway pathology. • At 8 mos of age, tracheostomy is discussed with parents. • Cardiac cath demonstrates elevated Glenn pressures, collateral vessels.

  39. Case 3 • Ethan’s Glenn is taken down at 9 mos age, 6-mm central shunt and new temporary pacing wires placed. • Develops slow junctional rhythm and evidence of pacemaker dependence. • Fails extubation repeatedly. Tracheostomy at 11 mos. Transitions to trach collar. • Starts having intractable seizures, requires 3 anticonvulsants for control. • Head CT scan shows diffuse hypoxic ischemic injury. • “When our son…”

  40. Case 3 • Ethan celebrates 1st birthday in PSHU. • Mom researches and suggests switching him to ketogenic formula. • After discussion with Neurology, Ketocal is started. • He finally starts gaining weight. • He develops complete pacemaker dependence; when temporary wires malfunction, he rapidly decompensates. • When presented with need for PPM, parents hesitate. Option of palliative care is presented. • “The staff was…”

  41. Parental Perceptions • Importance of effective communication: • Honest, complete information. • Delivered in timely, compassionate manner. • Understandable language. • Availability of medical staff for discussions. • Conflicting information, “too many cooks in the kitchen” = mistrust. • Displaying empathy, emotion = support. • Sensitivity, interpersonal skills felt to be more important than professional status. • Loss of control • Involvement in decision-making. • Spirituality and religion. • Prayer, access to clergy, faith. • Connection to child.

  42. Case 3 • 2 weeks later, a staffing is held. Parents request LET (limited end-of-life therapy) orders. • A week later, parents disclose that they would like to discontinue pacing soon. • They request comfort care in the interim, minimal blood draws, positive energy, respect of their privacy. • Ethan develops respiratory illness; parents consent to work-up, antibiotics. • Though initially hesitant, his parents consent to transfer to Step-down Unit. • “After exhausting every…”

  43. Parental Perceptions • Transcendent quality of parent-child relationship. • Value of parental contribution to child’s care. • Importance of time alone with child. • Evaluation of meaning of loss. • Altruism • Organ donation. • Relief of external signs of pain, suffering. • Continuation of bereavement support after death. • Sense of community within hospital. • MDs, nurses often considered more involved during dying process than other family, friends.

  44. Case 3 • On the selected day, at nearly 14 mos age, Ethan is transferred to a private room. • Feeds and medications are discontinued. Fentanyl and versed infusions are started for comfort. • Family and medical staff are invited to say their goodbyes. • That evening, per his parents’ wishes, his pacemaker was stopped and wires were cut. • “On Ethan’s final day…”

  45. “Anyone can slay a dragon. It takes a real hero to wake up every day and learn to love the world all over again.”
