Rehospitalization risk of former voluntary and involuntary patients with schizophrenia.

BACKGROUND: The aim of the study was to examine the differences between former involuntary and voluntary patients with a schizophrenic disorder with regard to time to and frequency of rehospitalization. METHODS: In this prospective observational study, 374 patients with a diagnosis of schizophrenia or schizoaffective disorder were included. At the time of inclusion, 290 (77.5 %) were hospitalized voluntarily and 84 (22.5 %) involuntarily. Follow-up assessments were conducted half-yearly over a 2-year period with measures of PANSS, GAF, sociodemographic data and cognitive functioning. These data served as covariates for adjustment in statistical models that included a Cox regression model, a random-effect logit model and a random-effect tobit model. RESULTS: After adjustment for other relevant covariates, the Cox regression showed that involuntary treatment is a significant risk factor of subsequent rehospitalization (HR = 1.53; CI = 1.06, 2.19; p = 0.02). The involuntary group had higher half-year incidence rates of rehospitalization, and in case of rehospitalization the duration of hospital stay was longer. CONCLUSIONS: Involuntary hospitalization seems to be associated with a higher risk of rehospitalization and longer subsequent hospital stays in patients with schizophrenia and schizoaffective disorders. Further studies are needed to examine in detail the processes and interventions that are suitable for interrupting circles of repeated hospitalizations, especially in former involuntary patients.

Long-term effects of involuntary hospitalization on medication adherence, treatment engagement and perception of coercion.

PURPOSE: The purpose of the study was to examine the long-term influence of involuntary hospitalization on medication adherence, engagement in out-patient treatment and perceived coercion to treatment participation. METHODS: In a naturalistic observational multi-centre study, 290 voluntarily and 84 involuntarily hospitalized patients with schizophrenia or schizoaffective disorder had been followed up over a period of 2 years with half-yearly assessments. Assessments included self-rated medication adherence, externally judged medication adherence by blood levels, engagement in treatment and perceived coercion. The statistical analyses were based on multilevel hierarchical modelling of longitudinal data. Level and development of the outcome was controlled for involuntariness, for sociodemographic characteristics and clinical history. RESULTS: Involuntariness of the index-hospitalization did not have an effect on the development of treatment engagement or medication adherence judged by blood levels in the course of the follow-up period when the models were controlled for sociodemographic variables and clinical history. It was associated, though, with a continuously lower self-rated medication adherence. Moreover, former involuntarily hospitalized patients more often felt coerced in several treatment aspects at the follow-up assessments. Yet, there was no difference between the voluntary and involuntary group with regard to the development of the levels of adherence or coercion experiences over time. CONCLUSIONS: Involuntary hospitalization does not seem to impair future treatment engagement in patients with schizophrenia, but formerly involuntarily hospitalized patients continue to be more sensitive to subjective or real coercion in their treatment and more vulnerable to medication non-adherence. Hereby, their risk of future involuntary hospitalization might be increased.

Effectiveness of antipsychotic maintenance therapy with quetiapine in comparison with risperidone and olanzapine in routine schizophrenia treatment: results of a prospective observational trial.

Objective of this observational trial is to examine the effects of quetiapine in comparison with olanzapine and risperidone on clinical outcomes and quality of life in patients with schizophrenia and schizoaffective disorder in routine care. 374 adult persons with schizophrenia or schizoaffective disorder prescribed antipsychotic maintenance therapy with quetiapine, olanzapine, or risperidone at discharge from inpatient treatment were included. Clinical and psychosocial outcomes were assessed before discharge and at 6, 12, 18, and 24 months. Statistical analyses were conducted by mixed-effects regression models for longitudinal data. The propensity score method was used to control for selection bias. Patients discharged on olanzapine had significantly lower hospital readmissions than those receiving quetiapine or risperidone. The average chlorpromazine equivalent dose of quetiapine was higher than in patients treated with olanzapine or risperidone. No further significant differences between treatment groups were found. Quetiapine and risperidone are less effective in preventing the need for psychiatric inpatient care than olanzapine, and higher chlorpromazine equivalent doses of quetiapine are needed to obtain clinical effects similar to those of olanzapine and risperidone.

[Psychiatric care between World War II and "Psychiatrie-Enquête": early approaches of reformation in Württemberg]. / Psychiatrische Versorgung zwischen Zweitem Weltkrieg und Psychiatrieenquete: Frühe Reformansätze in Württemberg.

OBJECTIVE: The article describes care in a psychiatric clinic between 1946 and 1975. This happens against the background of the current psychiatry-historical literature in which this phase of psychiatric care is described often summarily with the destructive words of the report of the 'Psychiatrie-Enquête' of 1975. Improvements achieved in this time were hardly examined up to now though they contributed substantially to the later effects of the 'Psychiatrie-Enquête'. METHODS: The medical annual reports of the psychiatric clinic of Zwiefalten, today ZfP Südwürttemberg, refering to the mentioned period were sighted and evaluated concerning their contents. RESULTS: In the called period evident organizational and structural defects are deplored in the annual reports. Nevertheless, from the late 1940 s on, modern care elements appear, as for example the broadening of the range of the therapeutic offers, multiprofessional treatment, diagnosis-specific concepts for the wards, opening of stations and extensive outpatient care. CONCLUSION: It is shown that already before the appearance of the final report of the Enquête commission clear progress concerning psychiatric care was achieved.

Identification of psychopathological course trajectories in schizophrenia.

Course trajectory analyses have been performed primarily for treatment response in acute episodes of schizophrenic disorders. As yet, corresponding data for the long-term course are lacking. Within a multicenter prospective observational study, 268 patients with schizophrenia were assessed at discharge from hospital and followed up after 6, 12, 18, and 24 months. A latent class growth analysis was performed on the scores from the Positive and Negative Syndrome Scale (PANSS). A two-class conditional latent class model showed the best data fit (Entropy: 0.924). The model divided the sample into a group with amelioration in all PANSS subscales (60%) and a group with stable positive/negative and deteriorating general psychopathology symptoms (40%). Global functioning (GAF score), gender, age, living situation and involuntary admission predicted course trajectory class membership. The model was predictive of significant differences between the two groups in health care service costs and quality of life. The results underline the heterogeneous course of the illness, which ranged from amelioration to deterioration over a 2-year period. Statistical models such as trajectory analysis could help to identify more homogenous subtypes in schizophrenia.

Adherence styles of schizophrenia patients identified by a latent class analysis of the Medication Adherence Rating Scale (MARS): a six-month follow-up study.

The purpose of this study was to examine patients' response profiles to the Medication Adherence Rating Scale (MARS) and to evaluate the potential of response styles as predictors of the future course of psychotic disorders in terms of rehospitalisation and maintenance of medication. A total of 371 psychiatric in-patients with schizophrenia or schizoaffective disorder who were taking part in a naturalistic long-term study completed a German version of the MARS. A Latent Class Analysis (LCA) was performed. Five latent classes of response styles could be identified: "moderately adherent", "critical discontinuers", "good compliers", "careless and forgetful", and "compliant sceptics". Class membership was found to be related to the severity of symptoms, level of functioning, insight into illness, insight into necessity of treatment, treatment satisfaction and medication side effects. At a six-month follow-up appointment, significant differences between the classes persisted. Participants showing a "good compliers" response pattern had a significantly better prognosis in terms of rehospitalisation rate and maintenance of the original medication than "critical discontinuers". Evaluation of the MARS by studying response profiles provides informative results that reach beyond the results obtained by an evaluation by scores. Patients can be classified into adherence groups that are of predictive value for long-term patient outcome.
