Background This study assesses how pediatric assent is conceptualized and justified within the therapeutic context. Pediatric ethicists generally agree that children should participate in medical care decisions in developmentally appropriate ways. Much attention has been paid to pediatric assent for research participation, but ambiguities persist in how assent is conceptualized and operationalized in the therapeutic context where countervailing considerations such as the child’s best interest and parental permission must also be weighed.Methods Searches were conducted in 11 databases including PubMed, Embase, (...) Cochrane Library, and Web of Science. Articles published between 2010 and 2020 were screened in COVIDENCE for meeting each of four criteria: (1) focusing on pediatric assent, (2) focusing on clinical care, (3) including normative claims, and (4) containing substantive statements about the meaning of pediatric assent. Full texts were abstracted for (1) operational definitions of assent, (2) discussion of the temporal nature of assent, (3) description of the concept of “understanding,” and (4) ethical justifications for soliciting assent. These excerpts were coded and code patterns formed themes presented in the results.Results The final analytic data set contained 29 articles. Analysis yielded three key themes. First, valid assent varies by treatment, population (e.g., younger versus older), and geographic/cultural context. Second, assent represents two distinct longitudinal processes: One involves eliciting preferences over a disease course or care episode; the other focuses on children’s developmental maturation. Third, ethical justifications for assent draw variously on instrumental and intrinsic reasons, but often remain ambiguous.Conclusions There is widespread agreement that assent is morally valuable, but there remain substantial ambiguities or disagreements about its meaning, process, and ethical justification.

Prader-Willi syndrome (PWS) is one of the 25 syndromic forms of obesity, in which patients present—in addition to different degrees of obesity—intellectual disability, endocrine disturbs, hyperphagia and/or other signs of hypothalamic dysfunction. In front of a severe/extreme obesity and the failure of non-invasive treatments, bariatric surgery is proposed as a therapeutic option. The complexity of the clinical condition, which could affect the long-term effects of bariatric surgery, and the frequent association with a mild to severe intellectual disability raise some ethical (...) concerns in the treatment of obese PWS adolescents. This article analyses these issues referring to the principles of healthcare ethics: beneficence/non-maleficence (proportionality of treatments; minimisation of risks); respect of autonomy; justice. Based on these principles, three hypothetical scenarios are defined: (1) obese PWS adolescent, capable of making an autonomous decision; (2) obese PWS adolescent with a severe intellectual disability, whose parents agree with bariatric surgery; (3) obese PWS adolescent with a life-threatening condition and a severe intellectual disability, whose parents do not agree with bariatric surgery. The currently available evidence on efficacy and safety of bariatric surgery in PWS adolescents with extreme or severe obesity and the lack of adequate long-term follow-up suggests great caution even in a very life-threatening condition. Clinicians must always obtain a full IQ assessment of patients by psychologists. A multidisciplinary team is needed to analyse the clinical, psychological, social and ethical aspects and organise support for patient and parents, involving also the hospital ethical committee or, if necessary, legal authorities.
