NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Digital Psychosocial Follow-Up for Survivors of Childhood Critical Illness: A Systematic Literature Review
ABSTRACT
Background:
Pediatric survivors of critical illness often face persistent psychosocial challenges after PICU (Pediatric Intensive Care Unit) discharge, but follow-up support across hospital, home, community, and school settings remains inconsistent. Digital interventions could help bridge these gaps and support recovery.
Objective:
To systematically review the literature on digital psychosocial follow-up solutions for children who survived critical illness, describing target populations, intervention design, evaluation methods, and psychosocial effects.
Methods:
A systematic literature review was performed using the Scopus database, supplemented by backward citation searches and hand searches of related reviews. Eligible studies included children surviving medical conditions potentially requiring PICU care, implemented a digital intervention (excluding telephone-only), and evaluated psychological or social outcomes; studies published before 2010, in non-English languages, not peer-reviewed, lacking full text, not original research, involving mixed child-adult populations, or with unspecified participant age or diagnosis were excluded. The quality of the included studies was appraised with the MMAT (Mixed Methods Appraisal Tool) 2018. Owing to heterogeneity in populations, interventions, comparisons, outcomes, and study designs, a narrative synthesis was applied.
Results:
Thirty-three publications reporting on 31 unique studies (N=1,717 participants, ages 0–17) were included. The studies spanned North America, Europe, and Asia and were conducted in inpatient, outpatient, home, and school contexts. Interventions comprised web applications (n=9/31), mobile apps (n=7/31), social robots (n=6/31), video games (n=4/31), and mixed modalities (n=5/31). Many studies (n=18/31) engaged guardians as co-participants or co-developers along with children. Target conditions were predominantly cancer (n=11/31), type 1 diabetes (n=8/31), and asthma (n=7/31). Mixed methods designs were most common (n=11/31), followed by nonrandomized quantitative trials (n=7/31) and randomized controlled trials (n=6/31). Most studies reported positive psychosocial effects. Across outcomes, self-management (n=3/31) and quality of life (n=5/31) showed the most statistically significant (P<.05) benefits. Evidence for psychosocial outcomes was less consistent. The certainty of evidence was limited by a single-database search, single-reviewer screening, variable methodological quality, and heterogeneity.
Conclusions:
Digital psychosocial follow-up for childhood critical illness survivors appears feasible and promising, particularly for self-management and quality of life, but the evidence base is heterogeneous and methodologically constrained. To strengthen clinical translation, future work should prioritize rigorous trials, standardized and theory-informed pediatric psychosocial outcome sets, longer follow-up, transparent reporting, and equity-focused designs that integrate family-centered hybrid clinic-home pathways and, where feasible, predictive features.
