Implementing a distress screening program in a thoracic surgery service

Abstract

Introduction: The aim of the present study was to examine the diagnostic accuracy of screening tests in detecting cases requiring psychological intervention among patients referred for thoracic surgery.

Methods: Emotional distress was evaluated in 105 patients referred for thoracic surgery by means of a diagnostic psychological interview (criterion variable). The screening ability of the following methods was analyzed: the physician's opinion (Yes/No), Hospital Anxiety and Depression Scale (HADS), single-item interview: «Are you depressed?» (Depression Question, ADEP) (1-5) and the single-item interview: «Are you anxious?» (Anxiety Question, ANXQ) (1-5).

Results: According to the clinical interview, 34% of the patients were clinical cases requiring psychological intervention. The total HADS (cut-off point of 10) showed a sensitivity=0.89, specificity=0.75 and AUC=0.883; the ADEP scale (>1) showed a sensitivity=0.79, specificity=0.74 and AUC=0.795; the ANXQ scale (>1) showed a sensitivity=0.78, specificity=0.41 and AUC=0.690; and the physician's opinion showed a sensitivity=0.47 and specificity=0.86.

Conclusions: A high percentage of patients referred for thoracic surgery required psychological intervention. The best instrument to identify those patients requiring psychological care, taking a psychological interview as the criterion variable, was the total HADS score. This test is brief, simple and well accepted by patients; it is easy to implement within a thoracic surgery service and has a good diagnostic accuracy.
