Clinical predictors of response and remission in inpatients with depressive syndromes

Abstract Background Most predictor analyses search for single predictors or rely on data from randomized controlled trials. We aimed at detecting a set of clinical baseline variables for prediction of response and remission in 1014 naturalistically treated inpatients with major depressive episode treated for 53.62 ± 47.5 days. Methods A three-staged procedure was implemented. First, univariate tests were used for finding associations with baseline variables. Second, logistic regression and third-CART analyses were used to determine predictors of response to inpatient treatment. Results Presence of suicidality, a higher initial HAMD-21 total score, an episode length  Limitation Results were assessed by a post-hoc analysis, based on prospectively collected data. No controlled study design. Conclusion Contrary to current beliefs, baseline suicidality might be associated with higher chances for response. In addition, baseline severity might impact outcome depending on which criterion (remission or response) used.
