Depression and anxiety in hospitalized patients on contact precautions for multidrug-resistant microorganisms

Abstract

Background: Contact precautions for patients with multidrug-resistant organisms (MDROs) have been associated with adverse effects. The aim of this study was, therefore, to evaluate the level of anxiety and depression through different standardized scales in patients isolated by MDROs.

Methods: This is a case-control study with hospitalized patients on contact precautions for MDROs. A questionnaire survey was conducted to analyse the presence and level of depression and anxiety. A multivariable analysis was performed to define independent questions for anxiety/depression scores to create a short questionnaire facilitating a practical approach to the care of hospitalized patients with MDROs. A receiver operating characteristic (ROC) curve was plotted to determine the diagnostic ability of the simplified score.

Results: A total of 141 patients were included in the study, among whom 68 were isolated because of MDRO colonization while 73 were not isolated (control-group). Forty-five (31.9%) patients had some degree of anxiety. Patients in MDRO contact isolation had a higher level of anxiety than those who were not isolated (55.9% vs. 9.6%, p < 0.001). The equation obtained by multivariated analysis allowed for the construction of a score with ROC area of 0.949 and a sensitivity of 91.1%.

Conclusion: Contact isolation for MDROs is associated with increased depression and anxiety. A simple anxiety score was developed and should be validated for screening.
