Stem cell transplantation: risk factors for psychiatric morbidity.

The aim of this study was to determine the risk factors for psychiatric disorder in haematological cancer patients during hospitalization for stem cell transplantation. In this 3-year prospective study, 220 patients received stem cell transplantation at a single institution. Structured psychiatric interviews applying standardized diagnostic criteria were performed at hospital admission and weekly during hospitalization until discharge or death, yielding a total of 1,062 interviews. Psychiatric disorder (any depressive, anxiety, or adjustment disorder) prevalence at the time of hospital admission was 21% and psychiatric disorder incidence during post-admission follow-up was 22%. After adjusting for multiple confounders in multivariate logistic regression analyses, we found that younger age, women, a past psychiatric history, lower functional status, pain, smoking cessation, and higher regimen-related toxicity were significantly associated with psychiatric disorder risk. Our study findings may help to improve identification of the patients most at risk for psychiatric disturbances during hospitalization for stem cell transplantation.
