RESUMO
BACKGROUND: Spinal fusion is a common orthopedic surgery in children and adolescents and is associated with high pain levels postoperatively. If the pain is not well managed, negative outcomes may ensue. To our knowledge, there is no measure in English that assesses patient's satisfaction with postoperative pain management following idiopathic scoliosis surgery. The aim of the present study was to assess the psychometric properties of the satisfaction subscale of the English version of the Satisfaction of Adolescents with Postoperative pain management - idiopathic Scoliosis (SAP-S) scale. METHODS: Eighty-two participants aged 10-18 years, who had undergone spinal fusion surgery, fully completed the SAP-S scale at 10-14 days postdischarge. Construct validity was assessed through a principal component analysis using varimax rotation. RESULTS: Principal component analysis indicated a three-factor structure of the 13-item satisfaction subscale of the SAP-S scale. Factors referred to satisfaction regarding current medication received (Factor 1), actions taken by nurses and doctors to manage pain (Factor 2) and information received after surgery (Factor 3). Cronbach's alpha was 0.91, showing very good internal consistency. Data on satisfaction and clinical outcomes were also reported. CONCLUSION: The SAP-S is a valid and reliable measure of satisfaction with postoperative pain management that can be used in both research and clinical settings to improve pain management practices. Although it was developed and validated with adolescents who had undergone spinal fusion surgery, it can be used, with further validation, to assess adolescents' satisfaction with pain management in other postoperative contexts.
RESUMO
Background: Spinal fusion for scoliosis generates moderate to severe pain intensity. There are currently no instruments available to measure adolescents' satisfaction regarding post-spinal fusion pain management. Aims: To develop and validate a scale on satisfaction of adolescents regarding pain management following spinal fusion for scoliosis. Methods: A methodological design was used to develop and validate the French-Canadian scale "Satisfaction des Adolescents de la gestion de la Douleur postopératoire - Scoliose idiopathique (SAD-S)". A modified Delphi method, with seven healthcare professionals and 10 adolescents, was used to establish content validity of the SAD-S. A pre-test of the scale was conducted with 10 adolescents post-spinal fusion. The final version of the scale was validated through a pilot study with 98 adolescents following their surgery. Results: The SAD-S scale includes a total of 13 items. Principal component analysis yielded a two-factor structure (2 subscales): 1) Pain management education and 2) Education regarding medication. These two factors explained 47,8% of the total variance for satisfaction. A Cronbach's alpha of 0,84 was obtained for internal consistency. Conclusion: Validation of the SAD-S scale showed that it has good psychometric properties with this population. Further validation is required with a larger sample to pursue its validation.
Introduction: La chirurgie correctrice de la scoliose génère de la douleur postopératoire d'intensité modérée à sévère. Il n'existe pas d'instruments sur la satisfaction d'adolescents ayant eu recours à ce type de chirurgie quant à la gestion de leur douleur.Objectifs: Développement et validation d'une échelle pour mesurer la satisfaction d'adolescents ayant subi une chirurgie correctrice de la scoliose quant à la gestion de leur douleur postopératoire.Méthodes: Un devis méthodologique a été utilisé pour développer l'Échelle de Satisfaction des Adolescents de la gestion de la Douleur postopératoire Scoliose idiopathique (SAD-S). La validité de contenu du SAD-S a été évaluée selon la méthode Delphi modifiée avec sept professionnels de la santé et 10 adolescents. Un pré-test de l'instrument a été effectué auprès de 10 autres adolescents ayant subi cette chirurgie. Une étude de validation a ensuite été menée auprès de 98 adolescents en phase postopératoire.Résultats: Le SAD-S comprend 13 énoncés. L'analyse en composantes principales a permis de déterminer une structure à deux facteurs (sous-échelles): 1) enseignement sur la gestion de la douleur et 2) enseignement sur la médication. Ces facteurs permettent d'expliquer 47,8 % de la variance totale pour la satisfaction. Un alpha de Cronbach de 0,84 a été obtenu pour la consistance interne de l'échelle.Conclusion: Le SAD-S possède de bonnes propriétés psychométriques pour la mesure de la satisfaction auprès de cette clientèle. La validation de cet instrument devra être poursuivie à l'aide d'un échantillon plus grand.
