BACKGROUND: End-of-life care (EOLC) discussions and decisions are common in pediatric oncology. Interracial differences have been identified in adult EOLC preferences, but the relation of race to EOLC in pediatric oncology has not been reported. We assessed whether race (white, black) was associated with the frequency of do-not-resuscitate (DNR) orders, the number and timing of EOLC discussions, or the timing of EOLC decisions among patients treated at our institution who died. METHODS: We reviewed the records of 380 patients who died between July 1, 2001 and February 28, 2005. Chi(2) and Wilcoxon rank-sum tests were used to test the association of race with the number and timing of EOLC discussions, the number of DNR changes, the timing of EOLC decisions (i.e., DNR order, hospice referral), and the presence of a DNR order at the time of death. These analyses were limited to the 345 patients who self-identified as black or white. RESULTS: We found no association between race and DNR status at the time of death (p = 0.57), the proportion of patients with DNR order changes (p = 0.82), the median time from DNR order to death (p = 0.51), the time from first EOLC discussion to DNR order (p = 0.12), the time from first EOLC discussion to death (p = 0.33), the proportion of patients who enrolled in hospice (p = 0.64), the time from hospice enrollment to death (p = 0.2) or the number of EOLC discussions before a DNR decision (p = 0.48). CONCLUSION: When equal access to specialized pediatric cancer care is provided, race is not a significant factor in the presence or timing of a DNR order, enrollment in or timing of enrollment in hospice, or the number or timing of EOLC discussions before death

Donation after cardiac death (DCD) is uncommon in part because clinicians cannot prospectively identify patients who are likely to die within 60 min of withdrawal of life-sustaining treatments (LST). UNOS criteria exist but have not been validated. Consecutive patients electively withdrawn from LST at five university-affiliated hospitals were prospectively enrolled. Demographic and treatment characteristics were collected. Chi-square was used to determine risk for death within 60 min and validate the UNOS criteria. A total of 533 patients were enrolled. A total of 28 were excluded from this report due to age <18 years or failure to include time of death. Of 505 (95%) patients, 227 (45%) died within 60 min, 134 (27%) in 1-6 h and 144 (29%) >6 h after withdrawal of LST. A total of 29%, 52%, 65% and 82% of patients with 0,1,2 and 3 UNOS DCD criteria, respectively, died within 60 min of withdrawal of LST. The data validate the UNOS criteria. Patients with no criteria might be excluded from consideration for DCD. Those with more than one criterion are reasonable candidates, while those with a single criterion should be considered if a 50% failure rate for DCD is acceptable

OBJECTIVE: To examine physiologic and therapeutic changes following withdrawal of life-sustaining treatment in children. DESIGN: Retrospective chart review. SETTING: University-affiliated tertiary care pediatric hospital. PATIENTS: All patients who had life-sustaining treatment withdrawn over a 5-yr period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 125 charts were examined to obtain 50 in which the terminal event preceding death was withdrawal of life-sustaining treatment. Data are expressed as median (1st, 3rd quartiles). Median hospital stay before death was 20 days (1st and 3rd quartiles, 8 and 30). Median time from decision to withdraw life-sustaining treatment to actual withdrawal was 30 mins (1st and 3rd quartiles, 10 and 180). All interventions were simultaneously discontinued in 80% of patients with mechanical ventilation followed by vasopressors being most common. No patients had stepwise reduction in ventilator rate before discontinuing the mechanical ventilation. Devices were rarely removed from patients including endotracheal tubes. Time from withdrawal of life-sustaining treatment to death was 15 mins (5, 30); only seven patients took >60 mins to die. Multivariable analysis (Kruskal-Wallis test) of various factors revealed simultaneous withdrawal of life-sustaining treatment, female gender, and not having received renal therapy as hastening death. CONCLUSIONS: Forgoing life-sustaining treatment in a small cohort of children at a single institution follows a pattern: Most cases occur after prolonged intensive care unit stays, withdrawal of treatment occurs almost immediately after the decision to withdraw, most treatments are withdrawn simultaneously rather than sequentially, and most patients die within minutes of life-sustaining treatment cessation. This is the first pediatric study to report the time to death after withdrawal of life-sustaining treatment and factors associated with shorter time to death in children

Organ transplantation is one of the groundbreaking achievements in medicine in the 20th century. In the early days of transplantation, organs were obtained from non-heartbeating (NHB) cadavers. With time, better options for organ sources became available (for example, living-related and 'brain dead' donors), and the practice of obtaining organs from NHB cadavers fell out of favor. Improvements in the field of transplantation have led to an increased demand for organs. Various strategies have been employed recently to increase the supply, one of them being non-heartbeating organ donation (NHBOD). NHBOD can take place in controlled or uncontrolled circumstances. Recently, national organizations have supported and proposed guidelines for NHBOD and to aid clinicians in identifying potential donors. Outcomes of organs obtained from NHB cadavers are comparable to those obtained from heartbeating donors. The practice of NHBOD is increasing and has proven that it can contribute to increasing organ availability
