Abstract

We administered the Maudsley Personality Inventory (MPI) preoperatively to 303 patients with spinal diseases about to undergo surgery. Patients younger than 20 years, patients previously treated in the Department of Psychiatry, and patients with poor postoperative results were excluded. Patients with N-scores (neuroticism scale) of 39 points or greater or L-scores (lie scale) of 26 points or greater were regarded as "abnormal." Based on clinical definitions we identified 24 "problem patients" during the course and categorized them as "Unsatisfied," "Indecisive," "Doctor shoppers," or "Distrustful." Preoperative MPI categorized 26 patients as abnormal; 22 patients categorized as abnormal became problem patients (p<0.001). MPI sensitivity and specificity was 84.6% and 99.3%, respectively. Preoperative MPI to patients with spinal disease was found to be useful in detecting problem patients.

Résumé

Nous avons utilisé l'Inventaire de Personnalité de Maudsley (MPI) chez 303 malades avant qu'ils subissent une chirurgie vertébrale. Ont été exclus les patients de moins de 20 ans, les malades traités précédemment dans le Département de Psychiatrie, et les malades avec un mauvais résultat postopératoire. Les malades avec un "N Score" (échelle pour la névrose) de 39 points ou plus et/ou un "L-score" (échelle de situation) de 26 points ou plus ont été considérés comme "anormaux". Basé sur les définitions cliniques nous avons identifié 24 patients "à problème" pendant l'étude et les avons catégorisés comme "Insatisfait", Indécis", "acheteur du Docteur" ou "Méfiant". Le MPI pré-opératoire a catégorisé 26 malades comme "anormaux". Vingt deux d'entre eux sont devenus des malades à problèmes (p<0.001). La sensibilité et la spécificité du MPI étaient de 84.6% et 99.3%, respectivement. Le MPI pré-opératoire, appliqué à des malades avec une pathologie vertébrale a été utile pour détecter des malades "à problème".
