Adherence and medical outcomes in pediatric liver transplant recipients who transition to adult services

Abstract:  Non‐adherence to medications is associated with poor medical outcomes in adolescent transplant recipients. It is unclear whether non‐adherence is further compromised when transplant recipients transition to the adult health care system. The purpose of the present study was to examine whether adherence changes during transition. We reviewed the medical records of 14 recently transitioned patients and compared their adherence and corresponding medical outcomes before and after transition. These outcomes were also compared with two cohorts of patients receiving care solely in pediatric or adult services. Medication adherence, measured through the use of standard deviations of tacrolimus blood levels, was examined for all patients. We found that adherence to tacrolimus significantly decreased after transition. After transitioning, patients furthermore exhibited poorer adherence than patients in the other two cohorts did over time. This small retrospective study suggests that the period of transition from pediatric to adult transplant clinics is a vulnerable one. Larger, prospective investigations of the transition process are necessary before recommendations are made regarding interventions.

Improved Adherence and Outcomes for Pediatric Liver Transplant Recipients by Using Text Messaging

OBJECTIVE: The goal was to improve immunosuppressant adherence for pediatric patients with orthotopic liver transplants by using text messaging (TM). METHODS: A prospective study of sending TM reminders to the primary medication administrator (patient or caregiver) for pediatric transplant recipients was performed. Patient records were reviewed, comparing the year before and the year of the study. The SD of serum tacrolimus levels was used as an indicator of adherence. RESULTS: Forty-one patients provided consent. The median age was 15 years (range: 1–27 years), and the median age at the time of transplantation was 2 years (range: 4 months to 23 years). Fourteen patients (34%) were male. In 29 of 41 cases, the medications were self-administered by the patient. The mean duration of study was 13 ± 1.5 months. Twenty-two patients were receiving 1 immunosuppressant, 14 were receiving 2, and 5 were receiving 3. Thirteen patients (37%) stopped the study after 4 months. The mean tacrolimus level SD decreased from 3.46 μg/L before the study to 1.37 μg/L (P < .005). The number of immunosuppressants taken and patient self/caregiver medication administration did not significantly affect the results. The number of acute cellular rejection episodes decreased from 12 to 2 during the study. Risk factors for rejection were older age (17.67 vs 13.28 years) and administration of >1 immunosuppressant. CONCLUSION: We observed significant improvement in medication adherence and a reduction in rejection episodes with TM reminders for pediatric recipients of liver transplants.

Child and parental reports of bullying in a consecutive sample of children with food allergy

OBJECTIVE: The social vulnerability that is associated with food allergy (FA) might predispose children with FA to bullying and harassment. This study sought to quantify the extent, methods, and correlates of bullying in a cohort of food-allergic children. METHODS: Patient and parent (83.6% mothers) pairs were consecutively recruited during allergy clinic visits to independently answer questionnaires. Bullying due to FA or for any cause, quality of life (QoL), and distress in both the child and parent were evaluated via questionnaires. RESULTS: Of 251 families who completed the surveys, 45.4% of the children and 36.3% of their parents indicated that the child had been bullied or harassed for any reason, and 31.5% of the children and 24.7% of the parents reported bullying specifically due to FA, frequently including threats with foods, primarily by classmates. Bullying was significantly associated with decreased QoL and increased distress in parents and children, independent of the reported severity of the allergy. A greater frequency of bullying was related to poorer QoL. Parents knew about the child-reported bullying in only 52.1% of the cases. Parental knowledge of bullying was associated with better QoL and less distress in the bullied children. CONCLUSIONS: Bullying is common in food-allergic children. It is associated with lower QoL and distress in children and their parents. Half of the bullying cases remain unknown to parents. When parents are aware of the bullying, the child’s QoL is better. It is important to proactively identify and address cases in this population.

The Weight-Inclusive versus Weight-Normative Approach to Health: Evaluating the Evidence for Prioritizing Well-Being over Weight Loss

Using an ethical lens, this review evaluates two methods of working within patient care and public health: the weight-normative approach (emphasis on weight and weight loss when defining health and well-being) and the weight-inclusive approach (emphasis on viewing health and well-being as multifaceted while directing efforts toward improving health access and reducing weight stigma). Data reveal that the weight-normative approach is not effective for most people because of high rates of weight regain and cycling from weight loss interventions, which are linked to adverse health and well-being. Its predominant focus on weight may also foster stigma in health care and society, and data show that weight stigma is also linked to adverse health and well-being. In contrast, data support a weight-inclusive approach, which is included in models such as Health at Every Size for improving physical (e.g., blood pressure), behavioral (e.g., binge eating), and psychological (e.g., depression) indices, as well as acceptability of public health messages. Therefore, the weight-inclusive approach upholds nonmaleficience and beneficience, whereas the weight-normative approach does not. We offer a theoretical framework that organizes the research included in this review and discuss how it can guide research efforts and help health professionals intervene with their patients and community.

Prospective analysis of nonadherence in autoimmune hepatitis: a common problem.

Objectives: To prospectively assess nonadherence to medications, the relationship between nonadherence and medical outcome and the relationship between a psychiatric risk factor (posttraumatic stress) and nonadherence in patients with a diagnosis of autoimmune hepatitis. Patients and Methods: Data were obtained in children with autoimmune hepatitis, who had consented to prospective monitoring of adherence, during 1 year of follow-up in our pediatric liver program. An electronic monitoring device as well as posttransplant trough blood levels of tacrolimus was used to evaluate adherence. A validated self-report questionnaire was used to assess posttraumatic stress. The medical outcome measure was the maximal alanine transaminase (ALT) for each monitored patient. Results: Of 37 pediatric patients, 34 (15 posttransplant) enrolled. Fourteen (41%) used the monitoring device as directed. Monitor readings ranged between 28% and 94% of optimal adherence (100%). No patient took the medications exactly as prescribed. Electronic monitoring device readings correlated inversely with maximal ALT (P = 0.03, r = −0.59), and were also correlated with the tacrolimus level variability as a measure of adherence (P = 0.04, r = −0.72). Posttraumatic stress disorder questionnaire scores were correlated with both measures of adherence (for electronic monitoring, P = 0.02, r = −0.70, for tacrolimus levels, P = 0.03, r = 0.62). Conclusions: Nonadherence to immunosuppressants was common in this cohort, and it correlated with higher maximal ALT. Nonadherence is therefore an important risk factor for poor outcome in patients with autoimmune hepatitis. Posttraumatic stress symptoms, which were correlated with nonadherence, may serve as a focus for adherence-improving interventions.

Transitioning health care responsibility from caregivers to patient: A pilot study aiming to facilitate medication adherence during this process

Abstract:  Transition in pediatric transplant recipients consists of both a physical shift in medical care location as well as a transition in health care responsibilities from caregivers to patients. The purpose of the present study was to test the feasibility of a pilot intervention aiming to facilitate the transition in health care responsibilities from caregivers to patients while patients are still receiving pediatric services. Twenty‐two patients were enrolled in a two‐session educational protocol aiming to facilitate transition of responsibility. Patients were recruited from an outpatient transplant clinic. Ten were referred because of suspected difficulty in transitioning of care, and 12 were consecutively recruited without any specific a priori concerns. Medication adherence, measured through the use of standard deviations of tacrolimus blood levels, and ALT levels were the medical outcome measures. Complete data are available for 20 patients. Mean ALT levels improved after the follow‐up period. For referred patients, adherence and ALT levels improved. Standard deviation of tacrolimus decreased from 3.33 to 2.23, t = 2.52, p = 0.04. Mean ALT decreased from 120.33 to 63.99, t = 3.01, p = 0.01. Maximal ALT values decreased overall from 284.10 to 101.20, t = 2.61, p = 0.03. Our findings suggest that targeted education regarding transition in responsibility for adolescents’ own health care is feasible in the outpatient environment and may assist families who are facing this potentially challenging process. A randomized, controlled study with a substantial number of enrolled patients is needed to establish the efficacy of this or other approaches.

Improving adherence to medications in pediatric liver transplant recipients.

Abstract:  We describe results from a clinical program, which aimed at improving adherence to medications in children who had a liver transplant. We followed the medical outcomes of 23 children and adolescents who participated in a clinical adherence‐improvement protocol during the years 2001–2002. The protocol included identification of non‐adherent patients by examining tacrolimus blood levels and intervention by increasing the frequency of clinic visits for non‐adherent patients. In the two‐yr preintervention (1999–2000), there was no improvement in any of the outcomes. After the intervention, the number of patients with high alanine aminotransferase levels (100 and above) decreased significantly, from eight before the intervention to four afterwards. Other outcomes, including the number of rejection episodes (three before, none after) and the degree of adherence to tacrolimus, also improved, but the improvement did not reach statistical significance. Although non‐adherent patients were called to clinic more often under the protocol, the intervention did not lead to increased outpatient costs. This adherence‐‐improvement intervention appears to be promising in improving outcomes in pediatric liver transplant recipients. Larger, controlled studies are needed to establish the efficacy of this or other approaches.

Mental Health and Quality-of-Life Concerns Related to the Burden of Food Allergy

As food allergy increases, more research is devoted to its influence on patient and family mental health and quality of life (QoL). This article discusses the effects on parent and child QoL, as well as distress, while appraising the limitations of knowledge given the methods used. Topics include whether QoL and distress are affected compared with other illnesses, assessment of distress and QoL in parents compared with children, concerns about food allergy-related bullying, and the necessity for evidence-based interventions. Suggestions are offered for how to improve QoL and reduce distress on the way to better coping with food allergy.

Screening for Depression and Suicidality in Patients With Cardiovascular Illnesses

The American Heart Association (AHA) and the American Psychiatric Association jointly recommend screening for depression in cardiology clinics. This includes screening for suicidality. It is not known how frequently patients disclose suicidal thinking (ideation) in this setting, and what proportion of those will turn out to have suicidal intent. Patients were screened for depression using a protocol identical to the one endorsed by the AHA in a cardiology community clinic in Elmhurst (Queens, New York). Depression was assessed using the Patient Health Questionnaire. Reports of suicidal ideation were immediately evaluated by a mental health professional. We determined the degree to which suicidal ideation was identified, the proportion of patients with suicidal intent of those reporting suicidal ideation, and the relation between depression and suicidal ideation in this setting. One thousand three patients were screened; 886 had complete Patient Health Questionnaire data. Of those, 12% (109 patients) expressed suicidal ideation. Four of those were hospitalized for suicidal intent (0.45% of all screened patients). Suicidal ideation and depression were correlated (point biserial correlation coefficient 0.478). In conclusion, suicidal ideation can and will be identified using the AHA depression screening recommendations, but only a very small fraction (0.45%) of screened patients will turn out to have suicidal intent. Discovery and stabilization of suicidal patients is an important benefit of the screening, but the fact that >12% of all screened patients will need to be immediately evaluated for suicidal intent has important implications for resource allocation to screening programs.
