[Effectivity of Inpatient Psychosomatic Treatment - Results of a Naturalistic Two-Year Survey in a Psychosomatic Service at a General Hospital].

BACKGROUND

Hospital psychosomatic treatment matches care expectations of a modern society. Evidence of its effectiveness through investigation in different settings is of importance because of prominent role of psychotherapy in German Healthcare System.

OBJECTIVE

First, to explore whether clinical as well as personal resources could improve significantly due to a hospital psychosomatic treatment. Second, to assess possible associations between outcome variables and other variables from the multidimensional profile of the sample.

METHOD

The sample consists of all 2014 - 2015 admitted patients who agree with investigation (N=283). Pre-post comparisons of results from validated questionnaires were performed by means of t-tests, including effect sizes. Associations between outcome variables (pre-post differences of clinical and resources related variables) and variables from the multidimensional profile were performed by means of bivariate and multivariate regression tests. Outcome differences were assessed by means of logistic regression models.

RESULTS

Drop-out-rate due to refusal of participation amounts 11.8%; from remaining participants uncompleted datasets additional 6.9%; due to declining further participation during hospitalisation additional 4.1% (total drop-out rate amounted 22.8%). Functionality, self-efficacy, disease severity, psychological as well as physical symptom burden, depressiveness, interpersonal concerns, and embitterment improved significantly (p<0.001) displaying effect sizes between 0.39 and 1.42 (average level for clinical variables 0.98). Considerable associations between clinical and resources related variables in both directions were found. 10% of patients reported worsening.

DISCUSSION

Psychosomatic hospital treatment is effective according to clinical improvement as well as to perceived quality of treatment. Clinical and resources related variables are positively bidirectional associated notwithstanding the kind of working causality. Robust prognostic factors are hard to identify.

CONCLUSIONS

Inpatient psychosomatic treatment is effective when the admission is indicated and the unit accomplishes mandatory quality criteria. The outcome occurs individually and is hard to be predicted. Depressiveness and embitterment could be considered as epiphenomena of all psychosomatic illnesses.
