The use of palliative chemotherapy in pediatric oncology patients: a national survey of pediatric oncologists

Evaluating palliative opportunities in pediatric patients with leukemia and lymphoma

BACKGROUND

Despite favorable prognoses, pediatric patients with hematologic malignancies experience significant challenges that may lead to diminished quality of life or family stress. They are less likely to receive subspecialty palliative care (PC) consultation and often undergo intensive end-of-life (EOL) care. We examined "palliative opportunities," or events when the integration of PC would have the greatest impact, present during a patient's hematologic malignancy course and relevant associations.

METHODS

A single-center retrospective review was conducted on patients aged 0-18 years with a hematologic malignancy who died between 1/1/12 and 11/30/17. Demographic, disease, and treatment data were collected. A priori, nine palliative opportunity categories were defined. Descriptive statistics were performed. Palliative opportunities were evaluated over temporal quartiles from diagnosis to death. Timing and rationale of pediatric PC consultation were evaluated.

RESULTS

Patients (n = 92) had a median of 5.0 (interquartile range [IQR] 6.0) palliative opportunities, incurring 522 total opportunities, increasing toward the EOL. Number and type of opportunities did not differ by demographics. PC consultation was most common in patients with lymphoid leukemia (50.9%, 28/55) and myeloid leukemia (48.5%, 16/33) versus lymphoma (0%, 0/4, p = 0.14). Forty-four of ninety-two patients (47.8%) received PC consultation a median of 1.8 months (IQR 4.1) prior to death. Receipt of PC was associated with transplant status (p = 0.0018) and a higher number of prior palliative opportunities (p = 0.0005); 70.3% (367/522) of palliative opportunities occurred without PC.

CONCLUSION

Patients with hematologic malignancies experience many opportunities warranting PC support. Identifying opportunities for ideal timing of PC involvement may benefit patients with hematologic cancers and their caregivers.

Leadership, behavioral science, and interprofessional teamwork

The greatest challenge I face as a pediatric oncologist is breaking life-threatening news to patients and their parents. I frequently felt the need to improve my ability to deliver such information in a professional, yet compassionate way. I was fortunate to participate in the Leadership Institute, which provided me with the skills and perspectives that inspired me to seek out team-centered methodologies and medical decision-making theories. After learning techniques for priority setting, situational leadership, expressing empathy, and conveying bad news, guidance from the Leadership Institute prompted me to collaborate with nursing, social work, and chaplaincy colleagues to develop a team-based approach for helping families facing end-of-life decisions. Our success in the clinical arena led to my leadership project, which focused on academic collaborations to develop an educational exercise for pediatric residents, and students in nursing, social work, and chaplaincy, designed to introduce learners to these techniques and the experience of conducting end-of-life discussions as part of an interprofessional team. We published an initial description of this 4-hour simulation-based training session and now plan to submit our cumulative 3-year quantitative and qualitative results. This commentary describes my growing appreciation of the power of behavioral medicine, and how the lessons learned through the Society of Behavioral Medicine and the Leadership Institute have not only facilitated the success of my project but also enriched multiple aspects of my professional life.

Predictors of Late Palliative Care Referral in Children With Cancer

CONTEXT

Early integration of palliative care (PC) in the management of children with high-risk cancer is widely endorsed by patients, families, clinicians, and national organizations. However, optimal timing for PC consultation is not standardized, and variables that influence timing of PC integration for children with cancer remain unknown.

OBJECTIVES

To investigate associations between demographic, disease, treatment, and end-of-life attributes and timing of PC consultation for children with high-risk cancer enrolled on a PC service.

METHODS

A comprehensive standardized tool was used to abstract data from the medical records of 321 patients treated at a large academic pediatric cancer center, who died between 2011 and 2015.

RESULTS

Gender, race, ethnicity, enrollment on a Phase I protocol, number of high-acuity hospitalizations, and receipt of cardiopulmonary resuscitation were not associated with timing of PC involvement. Patients with hematologic malignancy, those who received cancer-directed therapy during the last month of life, and those with advance directives documented one week or less before death had higher odds of late PC referral (malignancy: odds ratio [OR] 3.24, P = 0.001; therapy: OR 4.65, P < 0.001; directive: OR 4.81, P < 0.0001). Patients who received hospice services had lower odds of late PC referral <30 days before death (OR 0.31, P < 0.001).

CONCLUSION

Hematologic malignancy, cancer-directed therapy at the end of life, and delayed documentation of advance directives are associated with late PC involvement in children who died of cancer. Identification of these variables affords opportunities to study targeted interventions to enhance access to earlier PC resources and services for children with high-risk cancer and their families.

Patterns and Outcomes of Care in Children With Advanced Heart Disease Receiving Palliative Care Consultation

CONTEXT

Although access to subspecialty pediatric palliative care (PPC) is increasing, little is known about the role of PPC for children with advanced heart disease (AHD).

OBJECTIVES

The objective of this study was to examine features of subspecialty PPC involvement for children with AHD.

METHODS

This is a retrospective single-institution medical record review of patients with a primary diagnosis of AHD for whom the PPC team was initially consulted between 2011 and 2016.

RESULTS

Among 201 patients, 87% had congenital/structural heart disease, the remainder having acquired/nonstructural heart disease. Median age at initial PPC consultation was 7.7 months (range 1 day-28.8 years). Of the 92 patients who were alive at data collection, 73% had received initial consultation over one year before. Most common indications for consultation were goals of care (80%) and psychosocial support (54%). At initial consultation, most families (67%) expressed that their primary goal was for their child to live as long and as comfortably as possible. Among deceased patients (n = 109), median time from initial consultation to death was 33 days (range 1 day-3.6 years), and children whose families expressed that their primary goal was for their child to live as comfortably as possible were less likely to die in the intensive care unit (P = 0.03) and more likely to die in the setting of comfort care or withdrawal of life-sustaining interventions (P = 0.008).

CONCLUSION

PPC involvement for children with AHD focuses on goals of care and psychosocial support. Findings suggest that PPC involvement at end of life supports goal-concordant care. Further research is needed to clarify the impact of PPC on patient outcomes.

End-of-Life Care Patterns Associated with Pediatric Palliative Care among Children Who Underwent Hematopoietic Stem Cell Transplant

Stem cell transplantation (SCT) is an intensive therapy offering the possibility of cure for life-threatening conditions but with risk of serious complications and death. Outcomes associated with pediatric palliative care (PPC) for children who undergo SCT are unknown. Therefore, we evaluated whether PPC consultation is associated with differences in end-of-life (EOL) care patterns for children who underwent SCT and did not survive. Medical records of children who underwent SCT at Boston Children's Hospital/Dana-Farber Cancer Institute for any indication from September 2004 to December 2012 and did not survive were reviewed. Child demographic and clinical characteristics and PPC consultation and EOL care patterns were abstracted. Children who received PPC (PPC group) were compared with those who did not (non-PPC group). Children who received PPC consultation (n = 37) did not differ from the non-PPC group (n = 110) with respect to demographic or clinical characteristics, except they were more likely to have undergone unrelated allogeneic SCT (PPC, 68%; non-PPC, 39%; P = .02) or to have died from treatment-related toxicity (PPC, 76%; non-PPC, 54%; P = .03). PPC consultation occurred at a median of .7 months (interquartile range [IQR], .4 to 4.2) before death. PPC consultations most commonly addressed goals of care/decision-making (92%), psychosocial support (84%), pain management (65%), and non-pain symptom management (70%). Prognosis discussions (ie, the likelihood of survival) occurred more commonly in the PPC group (PPC, 97%; non-PPC, 83%; P = .04), as did resuscitation status discussions (PPC, 88%; non-PPC, 58%; P = .002). These discussions also occurred earlier in the PPC group, for prognosis a median of 8 days (IQR, 4 to 26) before death compared with 2 days (IQR, 1 to 13) in the non-PPC group and for resuscitation status a median of 7 days (IQR, 3 to 18) compared with 2 days (IQR, 1 to 5) in the non-PPC group (P < .001 for both of the timing of prognosis and resuscitation status discussions). The PPC group was also was more likely to have resuscitation status documented (PPC, 97%; non-PPC, 68%; P = .002). With respect to patterns of care, compared with non-PPC, the PPC group was as likely to die in a medicalized setting (ie, the hospital) (PPC, 84%; non-PPC, 77%; P = .06) or have hospice care (PPC, 22%; non-PPC, 18%; P = .6). However, among children who died in the hospital, those who received PPC were more likely to die outside the intensive care unit (PPC, 80%; non-PPC, 58%; P = .03). In addition, the PPC group was less likely to receive intervention-focused care such as intubation in the 24 hours before death (PPC, 42%; non-PPC, 66%; P = .02) or cardiopulmonary resuscitation (PPC, 3%; non-PPC, 20%; P = .03) at EOL. Children who received PPC for at least a month were more likely to receive hospice care (PPC, 41%; non-PPC, 5%; P = .01). Children who underwent SCT and did not survive were likely to die in a medicalized setting, irrespective of PPC. However, PPC was associated with less intervention-focused care and greater opportunity for EOL communication and advance preparation. In the intense, cure-oriented SCT setting, PPC may facilitate advance care planning in this high-risk population.

Referral practices of pediatric oncologists to specialized palliative care

PURPOSE

The aims of this study are to describe the attitudes and referral practices of pediatric oncologists (POs) to specialized palliative care (SPC), and to compare them with those of adult oncologists (AOs).

METHODS

Canadian members of the American Society of Pediatric Hematology/Oncology (ASPHO), Canadian Association of Medical Oncologists (CAMO), Canadian Association of Radiation Oncologists (CARO), and the Canadian Society of Surgical Oncology (CSSO) participated in an anonymous survey assessing SPC referral practices.

RESULTS

The response rate was 70 % (646/921), 52 % (43/82) for ASPHO members; 5 CARO members self-identified as POs, for a total of 48 POs and 595 AOs. Ninety-six percent of POs had access to inpatient SPC consultation services (vs. 48 % AOs), 31 % to a PCU (vs. 82 % AOs), and 27 % to an outpatient SPC clinic (vs. 73 % AOs). POs more often stated their SPC services accepted patients on chemotherapy than AOs (64 vs. 37 %, p = 0.0004). POs were less likely to refer only after chemotherapy had been stopped (13 vs. 29 % for AOs) and more likely to state that ideally referral should occur at the diagnosis of cancer/incurable cancer (73 vs. 43 %). POs were more likely to agree they would refer earlier if palliative care were renamed "supportive care" (58 vs. 33 %, p < 0.0001), that palliative care adds too many providers (17 vs. 7 %, p = 0.002), and that palliative care was perceived negatively by their patients (60 vs. 43 %, p = 0.02).

CONCLUSIONS

Although POs acknowledge the importance of early referral to SPC for children with cancer, there remain resource and attitudinal barriers to overcome in this regard.
