The estimated nonadherence rates, overall and by transplant type, allow clinicians to gauge patient risk and target resources accordingly. Nonadherence rates in some areas--including immunosuppressant use--appear unacceptably high. Weak correlations of most patient psychosocial factors with nonadherence suggest that attention should focus on other classes of variables (e.g., provider-related and systems-level factors), which may be more influential.

For patients receiving liver or other organ transplants for diseases associated with substance use, risk for relapse posttransplantation is a prominent clinical concern. However, there is little consensus regarding either the prevalence or risk factors for relapse to alcohol or illicit drug use in these patients. Moreover, the evidence is inconsistent as to whether patients with pretransplantation substance use histories show poorer posttransplantation medical adherence. We conducted a meta-analysis of studies published between 1983 and 2005 to estimate relapse rates, rates of nonadherence to the medical regimen, and the association of potential risk factors with these rates. The analysis included 54 studies (50 liver, 3 kidney, and 1 heart). Average alcohol relapse rates (examined only in liver studies) were 5.6 cases per 100 patients per year (PPY) for relapse to any alcohol use and 2.5 cases per 100 PPY for relapse with heavy alcohol use. Illicit drug relapse averaged 3.7 cases per 100 PPY, with a significantly lower rate in liver vs. other recipients (1.9 vs. 6.1 cases). Average rates in other areas (tobacco use, immunosuppressant and clinic appointment nonadherence) were 2 to 10 cases per 100 PPY. Risk factors could be examined only for relapse to any alcohol use. Demographics and most pretransplantation characteristics showed little correlation with relapse. Poorer social support, family alcohol history, and pretransplantation abstinence of Յ6 months showed small but significant associations with relapse (r ϭ 0.17-0.21). Future research should focus on improving the prediction of risk for substance use relapse, and on testing interventions to promote continued abstinence posttransplantation.

Background Adherence to the medical regimen after pediatric organ transplantation is important for maximizing good clinical outcomes. However, the literature provides inconsistent evidence regarding prevalence and risk factors for nonadherence posttransplant. Methods A total of 61 studies (30 kidney, 18 liver, 8 heart, 2 lung/heart-lung, and 3 with mixed recipient samples) were included in a meta-analysis. Average rates of nonadherence to 6 areas of the regimen, and correlations of potential risk factors with nonadherence, were calculated. Results Across all types of transplantation, nonadherence to clinic appointments and tests was most prevalent, at 12.9 cases per 100 patients per year (PPY). The immunosuppression nonadherence rate was 6 cases per 100 PPY. Nonadherence to substance use restrictions, diet, exercise and other healthcare requirements ranged from 0.6 to 8 cases per 100 PPY. Only the rate of nonadherence to clinic appointments and tests varied by transplant type: heart recipients had the lowest rate (4.6 cases per 100 PPY vs. 12.7–18.8 cases per 100 PPY in other recipients). Older age of the child, family functioning (greater parental distress, lower family cohesion), and the child’s psychological status (poorer behavioral functioning, greater distress) were among the psychosocial characteristics significantly correlated with poorer adherence. These correlations were small to modest in size (r =.12–.18). Conclusions These nonadherence rates provide benchmarks for clinicians to use to estimate patient risk. The identified psychosocial correlates of nonadherence are potential targets for intervention. Future studies should focus on improving the prediction of nonadherence risk and on testing interventions to reduce risk.

Background and aims For patients with end-stage liver disease commonly used indices of nutritional status (i.e. body weight and BMI) are often inflated due to fluid overload (i.e. ascites, peripheral edema) resulting in an underdiagnosis of malnutrition. As muscle is the largest protein reservoir in the body, an estimate of muscle mass may be a more reliable and valid estimate of nutritional status. Methods Therefore, we used pre-transplant computerized tomography data of 338 liver transplant (LTX) candidates to identify muscle and fat mass based on a specific abdominal transverse section commonly used in body composition analyses and investigated the contribution of this measure to specific post-LTX outcomes. Results We found the majority, 68%, of our patients could be defined as cachetic. For men muscle mass predicted many important post-transplant outcomes including intensive care unit (ICU) and total length of stay and days of intubation. Muscle mass was a significant predictor of survival and also predicted disposition to home vs another facility. For women muscle mass predicted lengths of ICU and total stay and days of intubation but the effect was modest. Muscle mass did not predict survival or disposition for women. Conclusions As pre-transplant muscle mass was associated with many important post-operative outcomes we discuss these findings in the context of possible pre-transplant interventions to either improve or sustain muscle mass before surgery.

Background Depression and anxiety are common mental health problems in transplant populations. There is mixed evidence concerning whether they increase morbidity and mortality risks post-transplant. If such associations exist, additional risk reduction strategies may be needed. Methods Four bibliographic databases were searched from 1981 through September, 2014 for studies prospectively examining whether depression or anxiety (determined with diagnostic evaluations or standardized symptom scales) affected risk for post-transplant mortality, graft loss, acute graft rejection, chronic rejection, cancer, infection, and rehospitalization. Results Twenty-seven studies (10 heart, total n=1,738; 6 liver, n=1,063; 5 kidney, n=49,515; 4 lung, n=584; 1 pancreas, n=80; 1 mixed recipient sample, n=205) were identified. In each, depression and/or anxiety were typically measured pre- or early post-transplant. Follow-up for outcomes was a median of 5.8 years (range:0.50–18.0). Depression increased the relative risk (RR) of mortality by 65% (RR=1.65, 95% CI:1.34,2.05; 20 studies). Meta-regression indicated that risk was stronger in studies that did (v. did not) control for potential confounders(p=.032). Risk was unaffected by type of transplant or other study characteristics. Depression increased death-censored graft loss risk (RR=1.65, CI:1.21,2.26, 3 studies). Depression was not associated with other morbidities (each morbidity assessed in 1–4 studies). Anxiety did not significantly increase mortality risk (RR=1.39, CI:0.85,2.27, 6 studies) or morbidity risks (assessed in single studies). Conclusions Depression increases risk for post-transplant mortality. Few studies considered morbidities; the depression-graft loss association suggests that linkages with morbidities deserve greater attention. Depression screening and treatment may be warranted, although whether these activities would reduce post-transplant mortality requires study.

Lung recipients were neither uniformly better nor worse than heart recipients in adhering to their regimen. Lung recipients have particular difficulty with some home monitoring activities. Strategies to maximize adherence in both groups should build on caregiver support and on strengthening financial resources for patient healthcare requirements.

WHAT'S KNOWN ON THIS SUBJECT: Racial/ethnic differences in care for adult and pediatric patients in the emergency department have been documented. WHAT THIS STUDY ADDS:This study reveals racial/ethnic differences in analgesic administration and prolonged length of stay for pediatric emergency department visits for abdominal pain. Documenting such disparities is an important first step needed to improve the equity of care for this and other conditions. abstract OBJECTIVE: To determine if race/ethnicity-based differences exist in the management of pediatric abdominal pain in emergency departments (EDs). METHODS: Secondary analysis of data from the 2006-2009 NationalHospital Ambulatory Medical Care Survey regarding 2298 visits by patients #21 years old who presented to EDs with abdominal pain. Main outcomes were documentation of pain score and receipt of any analgesics, analgesics for severe pain (defined as $7 on a 10-point scale), and narcotic analgesics. Secondary outcomes included diagnostic tests obtained, length of stay (LOS), 72-hour return visits, and admission. RESULTS:Of patient visits, 70.1% were female, 52.6% were from nonHispanic white, 23.5% were from non-Hispanic black, 20.6% were from Hispanic, and 3.3% were from "other" racial/ethnic groups; patients' mean age was 14.5 years. Multivariate logistic regression models adjusting for confounders revealed that non-Hispanic black patients were less likely to receive any analgesic (odds ratio CONCLUSIONS: Race/ethnicity-based disparities exist in ED analgesic use and LOS for pediatric abdominal pain. Recognizing these disparities may help investigators eliminate inequalities in care.[
