Psicooncología pediátrica: estándares de atención psicosocial y modelo de salud del cáncer en la infancia y adolescencia

Central Thesis and Objectives

The article presents a comprehensive analysis of standards of psychosocial care in pediatric psycho-oncology, with the objective of guiding and improving the quality of care received by families of children and adolescents diagnosed with cancer. The authors argue that consolidating a biopsychosocial approach in pediatric oncology requires evidence-based frameworks that orient clinical practice from diagnosis through survivorship.

Theoretical Framework

The work is founded on two main conceptual pillars. First, on the biopsychosocial approach to health and illness processes, which recognizes the need for comprehensive care that extends beyond physical aspects. Second, on the recognized importance of psychosocial care as a universal human right, endorsed by the Declaration of Lisbon (2014) from the International Psycho-Oncology Society, which establishes three basic principles: psychosocial cancer care must be recognized as universal right, quality oncology care must integrate psychosocial aspects in routine care, and emotional distress should be measured as the sixth vital sign.

The Spanish regulatory framework includes the Cancer Strategy of the National Health System (2021), which identifies specialized psychological care as a fundamental challenge, and the document on Standards and Recommendations of Quality and Safety in Pediatric Cancer Care Units (Spanish Ministry of Health, 2015), which recognizes psychological support as essential from the diagnostic phase.

Argumentative Development

Pediatric Psychosocial Care Standards

The authors present the 15 psychosocial care standards developed by Wiener et al. (2015), following a rigorous systematic review process based on the GRADE system. These standards include well-documented interventions with proven efficacy in clinical trials, alongside widely-used consensus interventions. Standards with strongest scientific support are: psychosocial assessment during cancer treatment and survivorship, neurocognitive monitoring for at-risk children, psychosocial support, and interventions for painful procedures. Other strong recommendation standards include: systematic evaluations of psychosocial care needs, access to psychosocial support and interventions throughout cancer trajectory, anticipated orientation regarding illness and effects, preparatory information about invasive medical procedures, opportunities for social interaction during treatment, team training, open collaboration between medical and psychosocial professionals, comprehensive team communication, support for siblings of patients, knowledge of palliative care concepts, routine adherence evaluation, family follow-up after child death, and specialized team training.

Pediatric Psychosocial Preventive Health Model (PPPHM)

The authors present Kazak's (2006) PPPHM, which establishes a preventive approach through three differentiated care levels according to family psychosocial need and risk. The Universal level comprises competent and well-adjusted families presenting distress but resilient, requiring general support, information, and risk indicator screening. The Focused level includes families with acute distress and present risk factors, needing specific information and distress monitoring. The Clinical level comprises families with persistent and increasing distress, requiring mental health specialist consultation. This model grounds the necessity to consider all families' biopsychosocial characteristics within the pediatric care system.

Screening Tools

To effectively implement the PPPHM, valid and reliable instruments are required. The Psychosocial Assessment Tool (PAT), developed and validated by Kazak et al. with a validated Spanish version available, evaluates seven psychosocial risk areas classifying families into the model's three levels. It is a brief screening tool applicable at diagnosis or subsequently, initiating preventive interventions and facilitating access to evidence-based care.

The Distress Thermometer (DT), proposed by the United States National Cancer Organization Network (NCCN), evaluates emotional distress on a 0-10 scale, incorporating a Problem List in five areas (practical, family, emotional, spiritual/religious, and physical). The DT has been adapted for pediatric population with age-differentiated versions: for children 2-4 years with facial expressions, for 5-6 years with visual analog scale, and for children over 7 years with numerical scale. Though of low specificity, it rapidly identifies those needing additional psychosocial evaluation.

Systematic evaluation approaches at initial moments after diagnosis offer greater benefits than the traditional reactive model based on referral for intense emotional distress, avoiding dangers to therapeutic relationship and effective treatment participation.

Specialized Psychological Interventions

For families requiring intervention beyond universal care, the work reviews evidence on psychological intervention efficacy. Meta-analyses show small to moderate effect sizes when analyzing diverse studies, but small or non-significant effects when selecting only Randomized Clinical Trials with greater homogeneity, evidencing need to increase quantity and methodological quality of pediatric psycho-oncology studies.

Implications

The article emphasizes that how families manage diagnosis and initial treatment moments establishes foundations for short and long-term adaptation. The proposed standards represent basic, not optimal, care in pediatric oncology, allowing cancer plans to identify strengths and areas requiring improvement or greater resource allocation. Quality comprehensive care must address all needs derived from diagnosis through preventive, planned, and evidence-based approaches, with universal access to early and effective psychosocial care standards being fundamental.

Importance and Contribution

This article constitutes a significant contribution to the pediatric psycho-oncology field by providing rigorous and updated synthesis of psychosocial care standards grounded in international evidence. Its importance lies in: (1) clarifying Spanish and international normative framework for psychosocial care in childhood cancer; (2) presenting an operationalizable theoretical model (PPPHM) enabling intervention stratification by need; (3) disseminating valid and culturally-adapted screening tools (Spanish PAT version, pediatric DT) facilitating early identification of at-risk families; (4) identifying standards with strongest scientific support to orient intervention priorities; and (5) highlighting necessity to increase quality research in pediatric psychological interventions. The authors emphasize that ensuring universal access to quality psychosocial care is both a human rights matter and clinical quality issue in pediatric oncology.
