Transition to adult care is a vulnerable period for pediatric transplant recipients and is associated with reduced medication compliance, graft loss, and increased mortality. Psychosocial outcomes in young adults differ between pediatric transplant recipients and their healthy peers. We conducted a single‐center, retrospective cohort study of all pediatric liver transplant recipients who were transitioned through our center. This study aimed to assess the outcomes of transitioned pediatric liver transplant recipients at an Australian center, including mortality, adherence, and psychosocial morbidity. The 1‐ and 5‐year survival rates following transition were 100% and 92%, respectively. There were no episodes of late rejection. In total, 66.7% of patients were compliant with immunosuppression and 61.1% of patients were compliant with clinic attendance. There was a significant relationship between medication compliance and clinic attendance, as well as presence of psychological issues with clinic non‐attendance. Psychosocial outcomes were in keeping with age‐matched data from the general population. All patients were employed or studying following transition. This is the first study of its kind in the Australian population, and outcomes were superior to published international data. Despite the demonstrated good outcomes, transition programs may improve healthcare engagement in this cohort. 相似文献

This study aimed both to evaluate caregivers' perspectives of EF and transition readiness among adolescent transplant recipients and to examine the indirect effects of adolescent responsibility and parent involvement across domains of EF. Fifty‐seven caregivers of adolescent solid organ transplant recipients participated in this study and completed measures of adolescent EF, transition readiness, responsibility in healthcare behavior, and parent involvement. Bootstrapping procedures were used to test indirect effects. Caregiver report of adolescent EF was significantly related to transition readiness among transplant recipients. Significant indirect effects were found for adolescent responsibility but not parent involvement. No significant differences were found between metacognitive and behavioral regulation domains of EF in the association with transition readiness. Assessment of adolescent EF skills may help guide the development of individualized transition readiness guidelines to promote successful gains in self‐management abilities as well as eventual transfer to adult medical services. 相似文献

Pediatric LT recipients are vulnerable to disruptions in their healthcare management and transitioning to self-managed care. This study aimed to examine whether age at transplant and indication for transplant (acute vs. chronic liver disease) influence later self-management skills. Sixty-three LT recipients, aged 14 and older (M = 17.68, s.d. = 3.01), were recruited and asked to complete a healthcare management survey, the Developmentally Based Skills Checklist, adapted for transplant patients, listing 22 behaviors that medically ill adolescents should progressively master. While there were no significant differences between those who received an LT owing to an acute disease vs. those who received an LT owing to a chronic disease, the age at which patients received their transplant did yield significant results, although, overall, these findings were attenuated by current age. However, our findings indicated that males transplanted at a younger age struggled with mastery over their healthcare responsibilities relative to males transplanted later and females in both age groups. There are many possible reasons why the experience of transplant at a younger age could negatively affect or derail healthcare transitions. Future research is necessary to further untangle this relationship; yet, it seems as though longer time living with LT may make transition harder for families. 相似文献

Given the increased risk for non‐adherence and poor health outcomes in late adolescence, there is a need for better methods to evaluate and improve the transition process as adolescent patients are prepared to be independent adults. This study assessed the psychometrics and concurrent validity of a newly developed measure of AoR for health management in pediatric liver transplant patients. A total of 48 patients and 37 parents completed a 13‐item measure of AoR. We performed an exploratory PCA on survey results and used component scores to assess the relationship between AoR and age, age at transplant, adherence, and health outcomes. Two primary components were identified: communication with the healthcare system and self‐management tasks. Parent perception of adolescent responsibility for tasks related to communicating with the healthcare system was correlated, in younger patients, with increased non‐adherence while responsibility for tasks related to self‐management was correlated, in older patients, with decreased non‐adherence. These results support AoR as a two‐domain construct, and they provide targets for monitoring and intervention as adolescent patients advance toward transfer. 相似文献

Non‐adherence is common in adolescent and young adult kidney transplant recipients, leading to adverse graft outcomes. The aim of this study was to determine whether adherence to immunosuppressant medications changes during transition from a pediatric to an adult program within the same transplant center. Adherence was assessed for a period of two yr before and two yr after the transfer. Subtherapeutic trough levels of serum tacrolimus and level variability were used as measures of adherence. Twenty‐five patients were transitioned between 1996 and 2011 at the median age of 22.3 [IQR 21.6–23.0] yr. Young adults 21–25 yr of age (n = 26) and non‐transitioned adolescents 17–21 yr of age (currently followed in the program, n = 24 and those that lost their grafts prior to the transfer, 22) formed the comparison groups. In the transitioned group, adherence prior to the transfer was not significantly different from the adherence after the transfer (p = 0.53). The rate of non‐adherence in the group of non‐transitioned adolescents who lost their grafts (68%) was significantly higher than in the transitioned group (32%, p = 0.01). In the group of young adults, adherence was not significantly different from the transitioned group (p = 0.27). Thus, transition was not associated with differences in medication adherence in this single‐center study. Large‐scale studies are needed to evaluate the national data on medication adherence after transfer. 相似文献

Abstract: 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. 相似文献

Cardiovascular diseases induce long‐term morbidity and mortality of adult LT recipients. The aim of this retrospective study was to assess CVRF, lipid abnormalities, and atherosclerosis (appraised by c‐IMT), more than 10 yr after pediatric LT. Thirty‐one children who underwent LT between December 1990 and December 2000 were included. Median age at LT was 14 months (range 4–64), and median follow‐up after LT was 11.9 yr (range 9.0–17.3). In our cohort, obesity (9.7%) and treated hypertension (9.7%) were rare. None of the patients was smoker or diabetic. High TC and TG were both observed in 6.5% of the patients. The mean c‐IMT for male patients was 1.22 ± 1.55 and 1.58 ± 1.23 mm in female patients. Seven patients (22%) had a mean c‐IMT above +2 s.d. Values below the 5th percentile were noted for LDL‐cholesterol (58.1%), HDL‐cholesterol (25.8%), apolipoprotein B (40%), and apolipoprotein A1 (20%). LDL‐cholesterol and apolipoprotein B levels were significantly lower in patients treated by tacrolimus in comparison with CsA (p < 0.05). In conclusion, our results suggest that pediatric LT patients do not present significant CVRF; moreover, instead of hyperlipidemia, hypocholesterolemia (LDL‐C) is frequent and immunosuppressive therapy is probably the cause. 相似文献

The transfer from pediatric to adult diabetes health care for emerging adults with type 1 diabetes (T1D) has received increasing attention in the literature. This review analyzes the effect of this health care transfer on the outcomes of diabetes care visit attendance, glycemic control, and acute diabetes‐related complications, and assesses the methodological strength of the studies reporting observational and interventional data. Observational studies, often limited by incomplete data, report a decline in diabetes care visits but an improvement or no change in hemoglobin A1c (HbA1c) after transfer to adult care. Results from studies reporting a transition intervention are restricted by lack of appropriate control groups and the collection of data both before and after transfer of care. Very few methodologically strong studies are available to guide clinicians with the transition from pediatric to adult care, and these shortcomings should be addressed in future studies designed to facilitate and improve the care of emerging adults with T1D. 相似文献

Assessment of transition readiness skills and adherence in pediatric liver transplant recipients.Pediatr Transplantation 2010: 14:944–953. © 2010 John Wiley & Sons A/S. Abstract: To examine transition readiness, adherence, and health outcomes in pediatric liver transplant recipients using a clinically administered screening measure. Seventy‐one pediatric liver transplant recipients (11–20 yr) and 58 parents completed a clinic‐based TRS measuring perceived and demonstrated self‐management skills, AoR for health‐related tasks, regimen knowledge, and psychosocial adjustment. Adherence was measured using s.d. of immunosuppressants, proportion of immunosuppressant blood levels out of target range, and clinic attendance. Health outcomes included liver test panels, biopsies, rejection episodes, and hospitalizations. Results indicate that all domains of transition readiness, with the exception of demonstrated skills, and non‐adherence were positively correlated with age. Proportion of immunosuppressant blood levels below target range was positively correlated with self‐management skills and increased responsibility for medication tasks. Parent regimen knowledge was associated with clinic attendance. Health outcomes were significantly related to medication non‐adherence, but not to transition readiness domains. Medication adherence is considered to be a key factor in the transition from pediatric to adult‐centered transplant care. Non‐adherence is associated with an increased risk for medical complications and is potentially modifiable. Interventions to promote self‐management skills and adherence should be an essential component of transition planning. 相似文献

Abstract: Non-adherence with recommended immunosuppressant medications is common post-pediatric liver transplant and is the most important reason for organ rejection in long-term survivors. However, there is currently no validated, standard method to measure adherence, with a well-defined threshold, making it extremely difficult to evaluate interventions to improve adherence. Previous studies have suggested that the degree of fluctuation of medication blood levels over time can provide an idea about how regularly the medication is being taken. The present study, conducted at UCLA medical center, sought to identify a specific threshold value of the s.d. of individual tacrolimus blood levels in pediatric liver transplant recipients which would be associated with rejection episodes in these patients. A threshold of 3.0 has been identified in other studies, and was supported by the analysis of retrospective data from 96 subjects. However, further analysis found that a s.d. of 2.5 appeared to have a better fit with the data. These findings suggest the utility of monitoring the s.d. of routine tacrolimus blood levels in pediatric liver transplant recipients for detecting non-adherence to immunosuppressant medication prior to clinical rejection, allowing earlier interventions. 相似文献

The liver's capacity to grow in response to metabolic need is well known. However, long‐term growth of liver allografts in pediatric recipients has not been characterized. A retrospective review of pediatric recipients at a single institution identified patients who had cross‐sectional imaging at 1, 5, and 10 years post‐transplant. Using volumetric calculations, liver allograft size was calculated and percent SLV were compared across the different time points; 18 patients ranging from 0.3 to 17.7 years old were identified that had imaging at 2 or more time points. Measured liver volumes increased by 59% after 5 years and 170% after 10 years. The measured liver volumes compared to calculated %SLV for these patients were 123 ± 37%, 97 ± 19%, and 118 ± 27% at 1, 5, and 10 years after transplant, respectively. Our data suggest that liver allografts in pediatric recipients increase along with overall growth, and reach SLVs for height and weight by 5 years post‐transplantation. Additionally, as pediatric recipients grow, the livers appear to maintain appropriate SLV. 相似文献

To summarize the evolution of the pediatric liver transplant program in a developing country. Between April 1997, and September 2003, 32 cadaveric (CD) and 35 living donor (LD) liver transplantations were performed on 61 children (median age 3.8 yr, range 0.5-16) at Ege University Organ Transplantation and Research Center. The patient's charts were reviewed retrospectively. The outcome of patient and graft survival was analyzed and the incidence of graft loss, complications and rejections was calculated. Indications for liver transplantation were metabolic liver disease (n = 17), biliary atresia (n = 14), viral hepatitis (n = 4), autoimmune hepatitis (n = 6), cryptogenic cirrhosis (n = 11), fulminant liver failure (n = 5) and others (n = 5). Seven of 61 children with chronic liver disease had hepatocellular carcinoma concomitantly. Median pediatric end-stage liver disease score was 23 (range 1-54). Seven children (11.4%) were UNOS status I, 44 (72%) were UNOS status II and 10 (16.6%) were UNOS status III. The median follow-up of the study population was 3.6 yr (range 0.5-6). Actuarial patient survival rates at 1, 2, 3 and 4 yr were 86, 86, 71.3 and 65% in the CD group vs. 80, 76, 67 and 67% in the LR group, respectively (p = NS). Patients listed as UNOS status 1 had lower survival rates than patients listed as UNOS status 2 and 3 (p < 0.05). The mortality rate was 26.2%. Graft survival rates were 81, 81, 75 and 64% at 1, 2, 3 and 4-yr respectively. Six patients (9%) underwent retransplantation. The main complications were infections (64.7%) and surgical complications (43.2%) (including biliary complication, vascular problems, postoperative bleeding, small for size and large for size). The incidence of acute cellular rejection was 39.3%, whereas chronic rejection was 7.4%. The result of liver transplantation in Turkish children was slightly inferior to those reported for North American and European children. However, an important characteristic of these patients that distinguishes them from Europe and North America is that most were UNOS status IIa and UNOS status I (44%). Despite technical and medical progress, infectious and biliary problems have continued to be an important cause of mortality in these patients. 相似文献

Non-adherence to a prescribed immunosuppressive regimen increases risk for late allograft rejection (LAR). We implemented a protocol for immunosuppression management which decreased variation in calcineurin inhibitor blood levels in pediatric liver transplant recipients by controlling for confounders such as physician practice variability. We hypothesized that patients with increased variation in tacrolimus blood levels despite implementation of the immunosuppression management protocol were at increased risk for LAR. We conducted a single center retrospective cohort study of 101 pediatric liver transplant recipients who were at least one year post liver transplantation and receiving tacrolimus for immunosuppression. The primary outcome variable was biopsy proven allograft rejection. Primary candidate predictor variables were the standard deviation (SD) of tacrolimus blood levels (a marker of drug level variability), mean tacrolimus blood level, age, and insurance type. SD of tacrolimus blood levels was determined for each patient from a minimum of four outpatient levels during the study period. Unadjusted and adjusted logistic regression models were used to determine the prognostic value of candidate predictors. The median and interquartile range of the SD of tacrolimus blood levels was 1.6 (1.1, 2.1). Eleven episodes of LAR occurred during the study period. Ten of the 11 episodes occurred in patients with tacrolimus blood level SD > 2. Insurance type, mean tacrolimus blood level and SD of tacrolimus blood levels were significantly related to LAR in the unadjusted analyses (p<0.05). A multivariable model including age, insurance type, mean and SD of tacrolimus blood levels was significantly associated with LAR (validated C-statistic = 0.88, p = 0.012). The adjusted odds of rejection for a one unit increase in the SD of tacrolimus blood level was 3.49 (95% CI 1.31 to 9.29). Effects of age and insurance status on LAR did not provide independent prognostic value after controlling for SD. Variation in tacrolimus blood levels is associated with an increased risk of LAR in pediatric liver transplant recipients. Despite standardized management of tacrolimus levels to control for confounders, some patients were found to have significant variability of tacrolimus blood levels. This may be due to non-adherence and amenable to targeted psychosocial and behavioral interventions to prevent LAR. 相似文献

The risk of adverse outcomes for pediatric renal transplant patients is highest during the transition from pediatric to adult care. While there have been many studies focus on graft failure and death, loss to follow‐up likely plays a large role in patient outcomes. We hypothesize patients are lost to follow‐up during this transition period and that patients transplanted at pediatric centers with a closely affiliated adult center (AFFs) are less likely to suffer from fragmentation of care and become lost to follow‐up. AFFs were defined as those pediatric centers whose transplant surgeons were also on staff at an adult center and were identified using center websites. We included patients undergoing renal transplantation at <=18 years of age and had data for the entire transition period on the Scientific Registry of Transplant Recipients (n = 6,762, 92.3% in 95 AFFs). 32% of patients were lost to follow‐up. On regression, patients transplanted at AFF were 33% less likely to be lost to follow‐up compared with those from non‐AFF (OR 0.67 CI 0.54‐0.82, P < 0.01). The proportion of patients lost to follow‐up during the transition period is remarkably high, but lower among recipients transplanted at AFFs. Poor follow‐up may be mitigated by improving integration of care. 相似文献
