Hospitalization of patients with schizophrenic and affective disorders in Israel in the aftermath of the structural and rehabilitation reforms

Risks for re-hospitalization of persons with severe mental illness living in rehabilitation care settings

BACKGROUND

The high rates of psychiatric re-hospitalizations (also termed "revolving door") presents a "wicked problem" which requires a systematic and holistic approach to its resolution. Israel's mental-health rehabilitation law provides a comprehensive set of services intended to support the ability of persons with severe mental illness to rely on community rather than in-patient facilities for their ongoing care needs. Guided by the Health Behavior Model, we examined the relationship between psychiatric re-hospitalizations and the three Health Behavior Model factors (predisposing factor: socio-demographic characteristics and health beliefs; enabling factor: personal and social/vocational relationships facilitated by rehabilitation interventions and services; and need factor: outcomes including symptoms, and mental health and functional status) among persons with severe mental illness receiving rehabilitation services.

METHODS

Logistic regression models were used to measure the association between re-hospitalization within a year and variables comprising the three Health Behavior Model factors on the sample of consumers utilizing psychiatric services (n = 7,165). The area under the curve for the model was calculated for each factor separately and for all three factors combined.

RESULTS

A total of 846 (11.8%) consumers were hospitalized within a year after the study began. Although multivariable analyses showed significant associations between re-hospitalization and all three Health Behavior Model factors, the magnitude of the model's area under the curve differed: 0.61 (CI = 0.59-0.64), 0.56 (CI = 0.54-0.58), 0.78 (CI = 0.77-0.80) and 0.78 (CI = 0.76-0.80) for predisposing, enabling, need and the full three-factor Health Behavior Model, respectively.

CONCLUSION

Findings revealed that among the three Health Behavior Model factors, the need factor best predicted re-hospitalization. The enabling factor, comprised of personal relationships and social/vocational activities facilitated by interventions and services representing many of psychiatric rehabilitation's key goals, had the weakest association with reduced rates of re-hospitalization. Possible explanations may be inaccurate assessments of consumers' personal relationships and social/vocational activities by the mental healthcare professionals, problematic provider-consumer communication on the consumers' involvement in social/vocational activities, or ineffective methods of facilitating consumer participation in these activities. Clearly to reduce the wicked "revolving-door" phenomenon, there is a need for targeted interventions and a review of current psychiatric rehabilitation policies to promote the comprehensive integration of community rehabilitation services by decreasing the fragmentation of care, facilitating continuity of care with other healthcare services, and utilizing effective personal reported outcomes and experiences of consumers with severe mental illness.

Temporal variation in the incidence of treated psychotic disorders in young people

INTRODUCTION

The incidence of psychotic disorders varies between geographical areas, however less is known about whether it varies over time in the same region. Analyzing this temporal variation of incidence could improve the allocation of healthcare resources and our understanding of the aetiology of psychotic disorders. This study aimed to determine whether there was a change in the incidence of psychotic disorders over a six-year period.

METHODS

Young people aged 15 to 24 presenting with a first episode of psychosis (FEP) attending an early intervention service in Melbourne between 2011 and 2016 were included. The population at-risk was determined from the two corresponding census periods and analyses were adjusted for age, sex and migrant status.

RESULTS

A total of 1217 young people presented with a FEP over the six-year period and the crude incidence rate in 2011 was 102.4 per 100,000 population at-risk, compared to 125.4 in 2016. There was an increase in the incidence by 33% in 2015 (aIRR = 1.33, 95% CI 1.09-1.63) and 28% in 2016 (aIRR = 1.28, 95% CI 1.05-1.56). When examined according to diagnostic groups, there was an increase in the incidence of substance-induced psychotic disorders among females in 2015 (aIRR = 4.62, 95% CI 1.02-20.8).

DISCUSSION

This study shows significant temporal variations in the incidence of treated psychotic disorders. These findings demonstrate that early intervention services should continually monitor incidence case numbers and funding should be provided accordingly, to ensure the required intensive and comprehensive treatments can be sustained.

The Effect of Community-Based Mental Health Rehabilitation Services for Schizophrenia: a Retrospective Cohort Study

Deliberative efforts are constantly made to provide community-based mental health rehabilitation services to people with mental health disabilities nationwide. In this study we aimed to assess the effectiveness of rehabilitation services in Israel by assessing the impact of utilization of rehabilitation services on hospitalization rates among a cohort of patients diagnosed with schizophrenia. Data derived from the Clalit Health Services were crossed with the Ministry of Health rehabilitation and psychiatric hospitalization case registries. Patients utilizing rehabilitation services were assessed for rates and durations of hospitalizations before and after the utilization of the rehabilitation services, and were compared to patients who did not use these services (n = 185). Mixed-model analyses of covariance (ANCOVA) were conducted to assess changes in rates and durations of hospitalizations at the beginning and end of the cohort period. Patients who used rehabilitation services showed higher rates and durations of hospitalizations prior to utilization of rehabilitation services, as well as higher decreases in number and duration of hospitalizations after utilizing their rights to rehabilitation services, as compared to patients who did not receive these services. Schizophrenia patients tend to show a decreasing trend in number and duration of hospitalizations over time. Nonetheless, the utilization of rehabilitation services offers larger gains in hospitalization prevention, primarily to schizophrenia patients who experience high rates and durations of hospitalizations at the beginning of illness. These findings provide additional support for the necessity of rehabilitation services, primarily for patients with severe onset.

A Method to Compare the Delivery of Psychiatric Care for People with Treatment-Resistant Schizophrenia

INTRODUCTION

Community services are gaining ground when it comes to attention to patients with psychiatric diseases. Regarding patients with treatment-resistant schizophrenia (TRS), the use of information and communication technology (ICT) could help to shift the focus from hospital-centered attention to community services. This study compares the differences in mental health services provided for patients with TRS in Budapest (Hungary), Tel-Aviv (Israel) and Catalonia (Spain) by means of a method for the quick appraisal of gaps among the three places, for a potential implementation of the same ICT tool in these regions.

METHODS

An adapted version of the Description and Standardised Evaluation of Services and Directories in Europe for Long Term Care (DESDE-LTC) instrument was made by researchers in Semmelweis University (Budapest, Hungary), Gertner Institute (Tel-Aviv, Israel) and Hospital de la Santa Creu I Sant Pau and Parc Sanitari Sant Joan de Déu (Catalonia, Spain).

RESULTS

Two types of outpatient care services were available in the three regions. Only one type of day-care facility was common in the whole study area. Two residential care services, one for acute and the other for non-acute patients were available in every region. Finally, two self-care and volunteer-care facilities were available in the three places.

CONCLUSION

Although the availability of services was different in each region, most of the services provided were sufficiently similar to allow the implementation of the same ICT solution in the three places.

Development and Validation of a Machine Learning Individualized Treatment Rule in First-Episode Schizophrenia

Importance

Little guidance exists to date on how to select antipsychotic medications for patients with first-episode schizophrenia.

Objective

To develop a preliminary individualized treatment rule (ITR) for patients with first-episode schizophrenia.

Design, Setting, and Participants

This prognostic study obtained data from Taiwan's National Health Insurance Research Database on patients with prescribed antipsychotic medications, ambulatory claims, or discharge diagnoses of a schizophrenic disorder between January 1, 2005, and December 31, 2011. An ITR was developed by applying a targeted minimum loss-based ensemble machine learning method to predict treatment success from baseline clinical and demographic data in a 70% training sample. The model was validated in the remaining 30% of the sample. The probability of treatment success was estimated for each medication for each patient under the model. The analysis was conducted between July 16, 2018, and July 15, 2019.

Exposures

Fifteen different antipsychotic medications.

Main Outcomes and Measures

Treatment success was defined as not switching medication and not being hospitalized for 12 months.

Results

Among the 32 277 patients in the analysis, the mean (SD) age was 36.7 (14.3) years, and 15 752 (48.8%) were male. In the validation sample, the treatment success rate (SE) was 51.7% (1.0%) under the ITR and was 44.5% (0.5%) in the observed population (Z = 7.1; P < .001). The estimated treatment success if all patients were given a prescription for 1 medication was significantly lower for each of the 13 medications than under the ITR (Z = 4.2-16.8; all P < .001). Aripiprazole (3088 [31.9%]) and amisulpride (2920 [30.2%]) were the medications most often recommended by the ITR. Only 1054 patients (10.9%) received ITR-recommended medications. Observed treatment success, although lower than the success under the ITR, was nonetheless significantly higher than if medications had been randomized (44.5% [SE, 0.55%] vs 41.3% [SE, 0.4%]; Z = 6.9; P < .001), although only marginally higher than if medications had been randomized in their observed population proportions (44.5% [SE, 0.5%] vs 43.5% [SE, 0.4%]; Z = 2.2; P = .03]).

Conclusions and Relevance

These results suggest that an ITR may be associatded with an increase in the treatment success rate among patients with first-episode schizophrenia, but experimental evaluation is needed to confirm this possibility. If confirmed, model refinement that investigates biomarkers, clinical observations, and patient reports as additional predictors in iterative pragmatic trials would be needed before clinical implementation.

Time trends in first admission rates for schizophrenia and other psychotic disorders in Taiwan, 1998-2007: a 10-year population-based cohort study

PURPOSE

To examine the trend in annual first admission rates for psychotic disorders as a whole as well as individual psychotic disorders in Taiwan from 1998 to 2007, and influences of age, sex, and geographic region on the trend.

METHOD

Using the inpatient claims records in the National Health Insurance Research Database, we estimated the yearly first admission rates for schizophrenia and other psychotic disorders, including voluntary (1998-2007) and involuntary (2004-2007) admissions. Both narrow and broad definitions of psychotic disorders were examined.

RESULTS

While involuntary first admission rates were stable, a crescendo-decrescendo change in voluntary first admission rates for psychotic disorders was observed, peaking in 2001. The increase from 1998 to 2001 was closely associated with health insurance expansion. Before 2001, the voluntary first admission rates in males aged 15-24 were underestimated as military personnel records were not included in the database. From 2001 to 2007, voluntary first admissions for psychotic disorders decreased 38%; the decrease could not be accounted for by the mild diagnostic shifts away from schizophrenia to affective psychosis or substance-induced psychosis. During the entire observation period, first admission rates for schizophrenia decreased 48%, while affective psychosis increased 84%. Gender disparities in the first admission rates gradually diminished, but geographic disparities persisted.

CONCLUSIONS

First admission rates for psychosis significantly reduced in Taiwan between 1998 and 2007, mainly driven by the reduced hospitalization risk for schizophrenia. Special attention should be paid to the increased hospitalization for other types of psychotic disorders (especially affective psychosis) and the unresolved geographic disparities.

The effects of pre-natal-, early-life- and indirectly-initiated exposures to maximum adversities on the course of schizophrenia

BACKGROUND

The effects of pre-natal-, early-life- and indirectly-initiated exposures to protracted maximum adversity on the course of schizophrenia are unknown.

AIMS

To compare the aforementioned Holocaust directly exposed subgroups with an indirectly exposed subgroup on the course of schizophrenia.

METHOD

The study population were: Israeli Jews in-uterus or born in Nazi-occupied or dominated European nations by the end of the persecution of the Jews, who were alive in 1950, and who had a last discharge diagnosis of schizophrenia in the Israel National Psychiatric Case Registry by 2013 (N=4933). The population was disaggregated into subgroups who (1) migrated after WWII and who had (1a) pre-natal (n=584, 11.8%) and (1b) early-life (n=3709, 75.2%) initiated exposures to the maximum adversities of the Holocaust, and (2) indirectly exposed individuals to the Holocaust who migrated before the Nazi-era persecution begun (n=640, 13%). Recurrent event survival analyses were computed to examine the psychiatric re-hospitalization risk of the study subgroups, unadjusted and adjusted for age of onset of the disorder and sex.

RESULTS

The pre-natal initiated exposure subgroup had a significantly (p<0.05) greater risk of psychiatric re-hospitalizations for schizophrenia than the other subgroups (unadjusted: HR=3.39, 95% CI 2.95, 3.90; adjusted: HR=2.28, 2.00, 2.60). This result replicated in sensitivity analyses for: Poland-born individuals, the years 1922 and 1935; and followed at least 10 years and to the year 2000.

CONCLUSIONS

Pre-natal initiated exposure to the maximal adversity of the holocaust constitutes a consistent risk factor for a worse course of schizophrenia, a possible byproduct of neurodevelopment disruptions induced by maternal stress and/or famine and/or infections.

Declines in psychiatric care in inpatient settings in Israel mirror global trend

Levinson and Lerner provide compelling evidence that reforms to the mental health system in Israel led to significant declines in institutional-based care. These declines are similar to those found in other high income countries over the same time period. Additional evidence on concurrent changes to the amount and quality of care in community settings is an important area for future research.
