Parents facing the death of their child have a strong need for compassionate professional support. Care services should be based on empirical evidence, be sensitive to the needs of the families concerned, take into account the heterogeneity within the medical field of paediatrics, and fit into the local health care system. We need to better understand the perspectives of parents facing the death of their child in order to guide further development and evaluation of specialised paediatric palliative and end-of-life (EOL) care services. Questionnaire survey to assess the EOL care perspectives of a Swiss population-based sample of bereaved parents who had lost a child due to a cardiac, neurological or oncological condition, or during the neonatal period in the years 2011 or 2012. The parental perspective was assessed with a newly developed and tested instrument that was structured according to six evidence-based quality domains. Responses regarding parental experiences and perceived satisfaction are described. Differences between the four diagnostic groups are analysed using a generalized estimation equation to account for the dyadic data structure. Of 307 eligible families, 267 could be contacted and 135 (51 %) consented to participate in this questionnaire survey. Our findings show positive parental experiences of their child’s EOL care and high perceived satisfaction with the care their child received. Parents of a child with cancer rated their experiences highest in most of the six quality domains and reported the highest satisfaction with care. The lowest scores were mainly reported by parents from the neurology group, with the exception of the shared decision making domain, where parents of neonates reported significantly less positive experiences. Although positive in general, our study results suggest some areas for improvement. The integration of specialised paediatric palliative care has the potential to minimise lost opportunities to support and assist parents.

An increased risk of becoming overweight has been reported for childhood cancer survivors (CCSs), in particular leukemia survivors, although the evidence is inconclusive. We assessed the prevalence of overweight in CCSs, with a focus on leukemia survivors, compared it with their peers, and determined potential risk factors. As part of the Swiss Childhood Cancer Survivor Study, we sent a questionnaire between 2007 and 2013 to all Swiss resident CCSs aged <21 y at diagnosis who had survived ≥5 y. We calculated body mass index (BMI) from medical records at diagnosis and self-reported heights and weights at survey. We calculated BMI z scores by using Swiss references for children and compared overweight prevalence in CCSs, their siblings, and the general population with the use of the Swiss Health Survey (SHS) and assessed risk factors for being overweight by using multivariable logistic regression. The study included 2365 CCSs, 819 siblings, and 9591 SHS participants. At survey, at an average of 15 y after diagnosis, the prevalence of overweight in CCSs overall (26%) and in leukemia survivors (26%) was similar to that in siblings (22%) and the general population (25%). Risk factors for being overweight in CCSs were male sex (OR: 1.8; 95% CI: 1.5, 2.1), both young (OR for ages 5–14 y: 1.6; 95% CI: 1.2, 2.3) and older (range—OR for ages 25–29 y: 1.7; 95% CI: 1.2, 2.4; OR for ages 40–45 y: 4.0; 95% CI: 2.5, 6.5) age at study, lower education (OR: 1.4; 95% CI: 1.1, 1.8), migration background (OR: 1.3; 95% CI: 1.1, 1.7), and no sports participation (OR: 1.4; 95% CI: 1.1, 1.7). Risk factors for overweight were similar in peers. CCSs treated with cranial radiotherapy (≥20 Gy) were more likely to be overweight than their peers (OR: 1.6; 95% CI: 1.2, 2.2). The prevalence of and risk factors for being overweight are similar in long-term CCSs and their peers. This suggests that prevention methods can be the same as in the general population. An important exception is CCSs treated with cranial radiotherapy ≥20 Gy who may need extra attention during follow-up care. This study was registered at clinicaltrials.gov as NCT03297034.

Paediatric end-of-life care is challenging and requires a high level of professional expertise. It is important that healthcare teams have a thorough understanding of paediatric subspecialties and related knowledge of disease-specific aspects of paediatric end-of-life care. The aim of this study was to comprehensively describe, explore and compare current practices in paediatric end-of-life care in four distinct diagnostic groups across healthcare settings including all relevant levels of healthcare providers in Switzerland. In this nationwide retrospective chart review study, data from paediatric patients who died in the years 2011 or 2012 due to a cardiac, neurological or oncological condition, or during the neonatal period were collected in 13 hospitals, two long-term institutions and 10 community-based healthcare service providers throughout Switzerland. Ninety-three (62%) of the 149 reviewed patients died in intensive care units, 78 (84%) of them following withdrawal of life-sustaining treatment. Reliance on invasive medical interventions was prevalent, and the use of medication was high, with a median count of 12 different drugs during the last week of life. Patients experienced an average number of 6.42 symptoms. The prevalence of various types of symptoms differed significantly among the four diagnostic groups. Overall, our study patients stayed in the hospital for a median of six days during their last four weeks of life. Seventy-two patients (48%) stayed at home for at least one day and only half of those received community-based healthcare. The study provides a wide-ranging overview of current end-of-life care practices in a real-life setting of different healthcare providers. The inclusion of patients with all major diagnoses leading to disease- and prematurity-related childhood deaths, as well as comparisons across the diagnostic groups, provides additional insight and understanding for healthcare professionals. The provision of specialised palliative and end-of-life care services in Switzerland, including the capacity of community healthcare services, need to be expanded to meet the specific needs of seriously ill children and their families.

Rationale: Childhood cancer survivors are at risk of long-term pulmonary dysfunction, but we lack sensitive outcome measures to detect early pulmonary damage. Objectives: To assess the ability of nitrogen multiple-breath washout (N2MBW) for detecting pulmonary dysfunction compared with spirometry in long-term survivors of childhood cancer. Methods: We analyzed cross-sectional data from long-term (≥5-yr) survivors of childhood cancer, aged ≤16 years at cancer diagnosis, ≥16 years at study (assessment period 2015–2019). We categorized survivors by risk: high risk for those having had pulmotoxic chemotherapy, chest radiation, thoracic surgery, and/or hematopoietic stem cell transplantation, and standard risk for other cancer therapies. Primary outcomes were the global lung clearance index (LCI) and acinar ventilation inhomogeneity index (SACIN) from N2MBW, and forced expiratory volume in 1 second (FEV1) and functional vital capacity (FVC) from spirometry. We calculated z-scores for N2MBW and spirometry parameters and compared pulmonary dysfunction between risk groups. Pulmonary dysfunction was defined as z-score +1.64 for N2MBW and −1.64 for spirometry. Results: We studied 46 survivors, median age at diagnosis 10 years (interquartile range, 4–14), median age at study 30 years (interquartile range, 25–40). Thirty-seven percent were at high risk and 63% at standard risk for pulmonary dysfunction. LCI and SACIN were higher in the high-risk group compared with the standard-risk group (mean LCI z-scores 2.09, standard deviation [SD] 2.39 vs. 0.95, SD 2.81; mean SACIN z-scores 2.45, SD 3.29 vs. 0.65, SD 2.79). FEV1 and FVC were lower in the high-risk compared with the standard-risk group (mean FEV1 z-scores −0.94, SD 1.39 vs. −0.10, SD 1.07; mean FVC z-scores −1.14, SD 1.23 vs. 0.15, SD 1.61). Overall, LCI, SACIN, FEV1, and FVC were abnormal in 60%, 53%, 33%, and 33% of high-risk patients compared with 23%, 21%, 0%, and 4% of standard-risk patients. Conclusions: N2MBW identified more cases of pulmonary dysfunction in long-term survivors of childhood cancer than spirometry, even in patients who had cancer therapy not specifically known as being pulmotoxic. N2MBW could be a complementary screening tool for early pulmonary damage after treatment for childhood cancer. Clinical trial registered with www.clinicaltrials.gov (NCT 02730767).
