Socio‐economic status and quality of life in children with chronic disease: A systematic review

Reduced quality of life (QoL) is a known consequence of chronic disease in children, and this association may be more evident in those who are socio-economically disadvantaged. The aims of this systematic review were to assess the association between socio-economic disadvantage and QoL among children with chronic disease, and to identify the specific socio-economic factors that are most influential. MEDLINE, Embase and PsycINFO were searched to March 2015. Observational studies that reported the association between at least one measure of social disadvantage in caregivers and at least one QoL measure in children and young people (age 2-21 years) with a debilitating non-communicable childhood disease (asthma, chronic kidney disease, type 1 diabetes mellitus and epilepsy) were eligible. A total of 30 studies involving 6957 patients were included (asthma (six studies, n = 576), chronic kidney disease (four studies, n = 796), epilepsy (14 studies, n = 2121), type 1 diabetes mellitus (six studies, n = 3464)). A total of 22 (73%) studies reported a statistically significant association between at least one socio-economic determinant and QoL. Parental education, occupation, marital status, income and health insurance coverage were associated with reduced QoL in children with chronic disease. The quality of the included studies varied widely and there was a high risk of reporting bias. Children with chronic disease from lower socio-economic backgrounds experience reduced QoL compared with their wealthier counterparts. Initiatives to improve access to and usage of medical and psychological services by children and their families who are socio-economically disadvantaged may help to mitigate the disparities and improve outcomes in children with chronic illnesses.

OBJECTIVE: Management of systemic lupus erythematosus (SLE) is complex and variability in practices exists. Guidelines have been developed to help improve the management of SLE patients, but there has been no formal evaluation of these guidelines. This study aims to compare the scope, quality, and consistency of clinical practice guidelines on the diagnosis, monitoring, and treatment of patients with SLE. METHODS: Electronic databases were searched up to April 2014. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument and textual synthesis was used to appraise and compare recommendations. RESULTS: Nine clinical practice guidelines and 5 consensus statements were identified, which covered 7 topics: diagnosis, monitoring, treatment, neuropsychiatric SLE, lupus nephritis, antiphospholipid syndrome, and other manifestations of lupus. The methodological quality of the guidelines was variable, with the overall mean AGREE II scores ranging from 31% to 75%, out of a maximum 100%. Scores were consistently low for applicability, with only 1 guideline scoring above 50%. There was substantial variability in the treatments recommended for class II and V lupus nephritis, the recommended duration of maintenance therapy for class III/IV lupus nephritis (from 1 to 4 years), and timing of ophthalmologic examination for patients taking corticosteroids. CONCLUSION: Published guidelines on SLE cover a complex area of clinical care, but the methodological quality, scope, and recommendations varied substantially. Collaborative and multidisciplinary efforts to develop comprehensive, high-quality evidence-based guidelines are needed to promote best treatment and health outcomes for patients with SLE.

Background and objectives Poor cognition can affect educational attainment, but the extent of neurocognitive impairment in children with CKD is not well understood. This systematic review assessed global and domain-specific cognition and academic skills in children with CKD and whether these outcomes varied with CKD stage. Design, setting, participants, & measurements Electronic databases were searched for observational studies of children with CKD ages 21 years old or younger that assessed neurocognitive or educational outcomes. Risk of bias was assessed using a modified Newcastle–Ottawa scale. We used random effects models and expressed the estimates as mean differences with 95% confidence intervals stratified by CKD stage. Results Thirty-four studies (25 cross-sectional, n =2095; nine cohort, n =991) were included. The overall risk of bias was high because of selection and measurement biases. The global cognition (full-scale intelligence quotient) of children with CKD was classified as low average. Compared with the general population, the mean differences (95% confidence intervals) in full-scale intelligence quotient were −10.5 (95% confidence interval, −13.2 to −7.72; all CKD stages, n =758), −9.39 (95% confidence interval, −12.6 to −6.18; mild to moderate stage CKD, n =582), −16.2 (95% confidence interval, −33.2 to 0.86; dialysis, n =23), and −11.2 (95% confidence interval, −17.8 to −4.50; transplant, n =153). Direct comparisons showed that children with mild to moderate stage CKD and kidney transplants scored 11.2 (95% confidence interval, 2.98 to 19.4) and 10.1 (95% confidence interval, −1.81 to 22.0) full-scale intelligence quotient points higher than children on dialysis. Children with CKD also had lower scores than the general population in executive function and memory (verbal and visual) domains. Compared with children without CKD, the mean differences in academic skills ( n =518) ranged from −15.7 to −1.22 for mathematics, from −9.04 to −0.17 for reading, and from −14.2 to 2.53 for spelling. Conclusions Children with CKD may have low-average cognition compared with the general population, with mild deficits observed across academic skills, executive function, and visual and verbal memory. Limited evidence suggests that children on dialysis may be at greatest risk compared with children with mild to moderate stage CKD and transplant recipients.

Toward Establishing Core Outcome Domains For Trials in Kidney Transplantation

BACKGROUND: Treatment decisions in kidney transplantation requires patients and clinicians to weigh the benefits and harms of a broad range of medical and surgical interventions, but the heterogeneity and lack of patient-relevant outcomes across trials in transplantation makes these trade-offs uncertain, thus, the need for a core outcome set that reflects stakeholder priorities. METHODS: We convened 2 international Standardized Outcomes in Nephrology-Kidney Transplantation stakeholder consensus workshops in Boston (17 patients/caregivers; 52 health professionals) and Hong Kong (10 patients/caregivers; 45 health professionals). In facilitated breakout groups, participants discussed the development and implementation of core outcome domains for trials in kidney transplantation. RESULTS: Seven themes were identified. Reinforcing the paramount importance of graft outcomes encompassed the prevailing dread of dialysis, distilling the meaning of graft function, and acknowledging the terrifying and ambiguous terminology of rejection. Reflecting critical trade-offs between graft health and medical comorbidities was fundamental. Contextualizing mortality explained discrepancies in the prioritization of death among stakeholders-inevitability of death (patients), preventing premature death (clinicians), and ensuring safety (regulators). Imperative to capture patient-reported outcomes was driven by making explicit patient priorities, fulfilling regulatory requirements, and addressing life participation. Specificity to transplant; feasibility and pragmatism (long-term impacts and responsiveness to interventions); and recognizing gradients of severity within outcome domains were raised as considerations. CONCLUSIONS: Stakeholders support the inclusion of graft health, mortality, cardiovascular disease, infection, cancer, and patient-reported outcomes (ie, life participation) in a core outcomes set. Addressing ambiguous terminology and feasibility is needed in establishing these core outcome domains for trials in kidney transplantation.
