The QoLISSY 0-4 questionnaire was developed as a Patient Reported Outcome measure (PROMS) to address the absence of an age-specific, condition-focused HRQoL assessment tool for this population. A mixed-method approach was employed to adapt the original QoLISSY questionnaire for children aged 5-18. Qualitative interviews were conducted with 24 parents of children diagnosed with short-stature conditions, including achondroplasia, small for gestational age, growth hormone deficiency, and Silver-Russell Syndrome. Cognitive debriefing sessions and iterative feedback guided the development of new items tailored to the needs of children aged 0-4. Pilot testing involved 20 parents, who evaluated the questionnaire's clarity, relevance, and comprehensiveness. The development process yielded an 8-domain, 55-item questionnaire addressing physical health, social interactions, emotions, coping mechanisms, medical care, future concerns, and parental impact. Cognitive debriefing results indicated high item clarity (100%), relevance (93%), and importance (94%), with parents confirming that the questionnaire effectively captured their child's HRQoL experiences. The QoLISSY 0-4 questionnaire provides a tailored, parent-reported tool for assessing HRQoL in children aged 0-4 with short stature.

However, these measures do not capture the primary reason patients seek surgery: relief from symptoms and an improved quality of life. Despite the evident patient-centered goal of non-cancer surgical procedures, research has long prioritized clinical parameters over patient-reported outcomes (PROs). A shift is essential to ensure that surgical success aligns with what truly matters to patients.</p><p><strong>Main body: </strong>Current surgical research and practice heavily rely on clinical benchmarks that do not adequately reflect patients' lived experiences. For non-cancer conditions, where surgery is elective and aims to enhance quality of life, PROs should serve as the primary indicators of success. Studies across various surgical disciplines have revealed discrepancies between clinical outcome measures and patient satisfaction, highlighting the need for validated, standardized PRO instruments. The Danish AFTERHERNIA Project exemplifies efforts to integrate PROs into surgical evaluations, utilizing digital health infrastructure to systematically capture patient experiences. Additionally, condition-specific tools, such as the Abdominal Hernia-Q, demonstrate the growing recognition of patient-centered metrics.
