This study examined the prevalence, demographic variables and adverse outcomes associated with non-adherence to post-transplant care in adolescent liver transplant recipients. We conducted a retrospective chart review of 111 adolescent patients (age 12-21 yr) greater than six months post-transplantation and defined non-adherence as not taking the immunosuppressive(s) or not attending any clinic visit in 2005. Fifty subjects (45.0%) were non-adherent and 61 (55.0%) were adherent. Twenty percent of the subjects did not attend clinic and 10.9% did not complete laboratory tests. Non-adherence was significantly associated with fewer completed laboratory tests (p < 0.0001), single parent status (p < 0.0186), and older age and greater years post-transplantation by both univariate and multivariate analyses (p < 0.008, p < 0.0141 and p < 0.0012, p < 0.0174, respectively). Non-adherence to medication was significantly associated with a rejection episode in 31 patients (p < 0.0069) but not in the subgroup of seven patients who stopped their immunosuppression completely. Non-adherence to post-transplant care is a prevalent problem in adolescents particularly of an older age and greater years post-transplantation. Rejection was a significant consequence of medication non-adherence except in a subgroup with presumed graft tolerance who discontinued their immunosuppression. These results emphasize the need for strict monitoring of adherence to post-transplant care to improve long-term survival and quality of life in adolescent transplant patients.

Few studies have examined the prevalence, demographic variables and adverse consequences associated with non-adherence to immunosuppressive therapy in the adolescent liver transplant population. Our hypothesis is that a significant proportion of adolescent liver transplant recipients exhibit non-adherence to medical regimens and that certain demographic and medical condition-related characteristics can be identified as potential predictors of non-adherent behavior. Furthermore, non-adherence leads to a greater incidence of morbidity and mortality in this population as compared with the adherent subset of adolescent patients. We reviewed the charts of 97 patients from 1987 to 2002 who by December of 2002 had survived at least 1 yr post-transplant and were followed by the Pediatric Liver Transplant Service at any point during their adolescent period (ages of 12-21). Non-adherence was defined as documentation of a report of non-adherence by a patient, parent or healthcare provider that was recorded in the patient's legal medical record. Descriptive statistics were used to determine the prevalence, demographic variables and adverse outcomes associated with non-adherence to immunosuppressive therapy. Categorical variables were analyzed using the chi-square test or the Fisher exact probability test. The unpaired Student's t-test was used to analyze the continuous variable of age at transplant. Using the inclusion criteria, a total of 97 patients represented the study sample of whom 37 subjects (38.1%) were defined as non-adherent and 60 (61.8%) were adherent. Non-adherent subjects were more likely to be female, older (>18 yr) and from a single-parent household. There was no significant difference in immunosuppressive regimen between non-adherent and adherent patients. Non-adherence was significantly (p<0.025) associated with lower socioeconomic status (SES), older age at transplant (p<0.005, 95% CI: -5.5 to -.99, Student's t-test) and episodes of late acute rejection (p<.001). Non-adherence was also significantly associated with re-transplantation and death secondary to chronic rejection by the Fisher exact test (p<0.006 and p<0.05, respectively). Non-adherence to immunosuppressive therapy is a prevalent problem that is correlated with certain demographic and medical condition-related risk factors and more frequent adverse consequences in the adolescent liver transplant population. The greater incidence of late acute rejection, death and re-transplantation owing to chronic rejection in non-adherent patients suggests that non-adherence is significantly associated with an increased risk of morbidity and mortality. Further investigation to identify patients at greatest risk for non-adherence is necessary to design the most effective intervention to increase patient survival and well being.

Combined liver-kidney transplantation for the infantile presentation of PH1 is associated with excellent outcome when the approach includes early diagnosis and early combined transplantation, aggressive pretransplant dialysis, and avoidance of posttransplant renal dysfunction.

In order to determine long-term outcome, including survival, growth and development, following liver transplantation in children with metabolic disorders, we retrospectively reviewed charts of 54 children with metabolic disorders evaluated from 1989-2005 for presenting symptoms, transplantation timing and indications, survival, metabolic parameters, growth, and development. Thirty-three patients underwent liver transplantation (12 received combined liver-kidney transplants) at a median age of 21 months. At a median follow-up of 3.6 yr, patient survival was 100%, and liver and kidney allograft survival was 92%, and 100%, respectively. For the group as a whole, weight Z scores improved and body mass index at follow-up was in the normal range. Two yr post-transplantation, psychomotor development improved significantly (p < 0.01), but mental skills did not; however, both indices were in the low-normal range of development. When compared to patients with biliary atresia, children with metabolic disorders showed significantly lower mental developmental scores at one and two yr post-transplantation (p < 0.05), but psychomotor developmental scores were not significantly different. We conclude that, in patients with metabolic disorders meeting indications for transplantation, liver transplantation or combined liver-kidney transplantation (for those with accompanying renal failure) is associated with excellent long-term survival, improved growth, and improved psychomotor development.

The cultural histories, values, and beliefs of families who are among the growing and diverse, non-white, non-Anglo population must be recognized and valued by early intervention specialists who provide family services. This article describes these concerns and suggests strategies for gathering information from these families.

A pain management intervention, consisting of pretransplant parental education and support, pre- and postoperative behavioral pediatrics consultation, postoperative physical and occupational therapy consultation, and implementation of non-pharmacologic pain management strategies, was introduced to all pediatrics patients receiving liver transplants at Lucile Packard Children's Hospital beginning August 2001. Children receiving transplants pre-intervention (May, 2000 to February, 2001) and post-intervention (August, 2001 to March, 2002) were compared using pain scores, parent perception of pain ratings, length of stay, ventilator days, total cost, and opioid use. A total of 27 children were evaluated (13 historical control, 14 intervention). The two populations did not differ on age at transplant (mean age 53.8 vs. 63.6 months), sex (46.1% vs. 50% male), ethnicity (53.8% vs. 57.1% white, non-Hispanic) weight at transplant (17.5 vs. 24.7 kg), percent with biliary atresia as the primary reason for transplant (42.9% vs. 69.2%), percent with status 1 transplant listing score (38.5% vs. 50.0%), or public insurance status (30.8 vs. 57.2% with Medicaid). No differences were found in mean pediatric intensive care unit (PICU) postoperative length of stay (6.7 vs. 5.3 days), total postoperative length of stay (17.5 vs. 17.5 days), total inpatient length of stay (27.0 vs. 24.4 days), time to extubation (30 vs. 24.3 h), total cost (dollar 147,983 vs. dollar 157,882) or opioid use through postoperative day (POD) 6 (0.24 vs. 0.25 mg/kg/day morphine equivalent). A decrease in mean pain score between POD 0 and 6 (2.82 vs. 2.12; p = 0.047), a decrease in mean parental pain perception score (3.1 vs. 2.1; p = 0.001), and an increase in number of pain assessments per 12 h shift (3.43 vs. 6.79; p < 0.005) were seen. A comprehensive non-pharmacologic postoperative pain management program in children receiving a liver transplant was associated with decreased pain scores, improved parent perception of pain, and an increased number of pain assessments per 12 h shift. No increases in lengths of stay (PICU, postoperative, total), time to extubation, or total cost were found.

Ethical and regulatory guidelines recommend disclosure of medical errors to patients and families. Yet few studies examine how to effectively train healthcare professionals to deliver communications about adverse events to family members of affected pediatric patients. This pilot study uses a preintervention-postintervention study design to investigate the effects of medical error disclosure training in a simulated setting for pediatric oncology nurses (N=16). The results of a paired t test showed statistically significant increases in nurses' communication self-efficacy to carry out medical disclosure (t = 6.68, p < .001). Ratings of setting "realism" and simulation effectiveness were high (21 out of 25 composite score). Findings provide preliminary support for further research on simulation-based disclosure training for healthcare professionals.
