Abstract:

Objective    To evaluate the prevalence of anxiety and depression in ICU patients receiving mechanical ventilation and analyze related factors．Methods     A questionnaire, composed of a general information form, acute physiology and chronic health evaluation score Ⅱ(APACHE II)，intensive care experience scale and hospital anxiety and depression scale, was used to investigate ICU patients receiving mechanical ventilation from a 3A-grade hospital in Jinan. 157 patients completed the questionnaire．The data was analyzed with the SPSS 12.0．Results    Among all the patients, 54.8% met criteria for anxiety and 74.5% met criteria for depression. The score of anxiety was correlated with scores of “inter-personal support demands”, “treatment and illness information” and “altered cognition and feeling”  subscales in the intensive care experience scale, the APACHE II score, mechanical ventilation time, and patient′s age. The score of depression was correlated with scores of “inter-personal support demands”, “treatment and illness information”, “altered cognition and feeling” and “awareness of surrounding”  subscales in the intensive care experience scale, and the APACHE II score. Conclusion    Anxiety and depression are particularly common among ICU patients receiving mechanical ventilation. The main related factors of anxiety and depression are bad intensive care experience and the severity of patient′s conditions.
