[Non-response to therapy in acute and rehabilitative psychosomatic inpatient care - a systematic review].

OBJECTIVES

The study reviews the state-of-the art on failure research in acute and rehabilitative psychosomatic inpatient care. The main focus of interest lies in describing the frequency and possible predictors of unsuccessful therapeutic treatments.

METHODS

We systematically searched the databases MEDLINE, PsycARTICLES, PsycINFO und PSYNDEX and selected studies from the past 20 years focusing on treatment failure in the inpatient psychosomatic treatment of adult patients.

RESULTS

A total of 31 studies were included, 15 of which allowed the extraction of predictors of non-response or deterioration. 20 %to 30%of patients leave psychotherapeutic treatment without any significant change; 5 %to 10%deteriorate during their stay.A high level of symptom distress at intake, a chronic course of the disease as well as somatoform or personality disorders are associated with non-response and deterioration. Early response to treatment and a dysfunctional therapeutic alliance are possible further predictors, whereas sociodemographic and sociomedical variables are unlikely to have a predictive validity.

CONCLUSIONS

Hypotheses about possible predictors can be derived from the results of this review. However, the interpretation of the results is limited by the heterogeneity of the methodology and of the samples of the studies included. Nevertheless the results can be used as a basis for further hypothesis-driven research.
