Service provision for people with schizophrenia. I. Clinical and economic perspective

Inpatient Mental Healthcare before and during the COVID-19 Pandemic

Prior studies have demonstrated disruption to outpatient mental health services after the onset of the COVID-19 pandemic. Inpatient mental health services have received less attention. The current study utilized an existing cohort of 33 Veterans Health Affairs (VHA) acute inpatient mental health units to examine disruptions to inpatient services. It further explored the association between patient demographic, clinical, and services variables on relapse rates. Inpatient admissions and therapeutic services (group and individual therapy and peer support) were lower amongst the COVID-19 sample than prior to the onset of COVID-19 while lengths of stay were longer. Relapse rates did not differ between cohorts. Patients with prior emergent services use as well as substance abuse or personality disorder diagnoses were at higher risk for relapse. Receiving group therapy while admitted was associated with lower risk of relapse. Inpatient mental health services saw substantial disruptions across the cohort. Inpatient mental health services, including group therapy, may be an important tool to prevent subsequent relapse.

Course of health care costs before and after psychiatric inpatient treatment: patient-reported vs. administrative records

BACKGROUND

There is limited evidence on the course of health service costs before and after psychiatric inpatient treatment, which might also be affected by source of cost data. Thus, this study examines: i) differences in health care costs before and after psychiatric inpatient treatment, ii) whether these differences vary by source of cost-data (self-report vs. administrative), and iii) predictors of cost differences over time.

METHODS

Sixty-one psychiatric inpatients gave informed consent to their statutory health insurance company to provide insurance records and completed assessments at admission and 6-month follow-up. These were compared to the self-reported treatment costs derived from the "Client Socio-demographic and Service Use Inventory" (CSSRI-EU) for two 6-month observation periods before and after admission to inpatient treatment to a large psychiatric hospital in rural Bavaria. Costs were divided into subtypes including costs for inpatient and outpatient treatment as well as for medication.

RESULTS

Sixty-one participants completed both assessments. Over one year, the average patient-reported total monthly treatment costs increased from € 276.91 to € 517.88 (paired Wilcoxon Z = -2.27; P = 0.023). Also all subtypes of treatment costs increased according to both data sources. Predictors of changes in costs were duration of the index admission and marital status.

CONCLUSION

Self-reported costs of people with severe mental illness adequately reflect actual service use as recorded in administrative data. The increase in health service use after inpatient treatment can be seen as positive, while the pre-inpatient level of care is a potential problem, raising the question whether more or better outpatient care might have prevented hospital admission. Findings may serve as a basis for future studies aiming at furthering the understanding of what to expect regarding appropriate levels of post-hospital care, and what factors may help or inhibit post-discharge treatment engagement. Future research is also needed to examine long-term effects of inpatient psychiatric treatment on outcome and costs.

Patterns of service utilisation in psychosis: findings of the 2010 Australian national survey of psychosis

OBJECTIVE

This paper reports patterns of health service utilisation in the second Australian national survey of psychosis corresponding with changes in available services of this period.

METHOD

Semi-structured interviews were carried out of an age-stratified random sample of adults who screened positive for psychosis. Multivariate logistic regressions were used to identify predictors of service use for a sample of 1825 individuals.

RESULTS

Use of psychiatric inpatient services was associated with higher symptom levels, suicidal ideation, poor social functioning and younger age. High users of emergency mental health services similarly reported higher symptom levels, poor functioning and younger age, and also reported being married or in a de facto relationship. Recipients of general practitioner services had greater anxiety symptoms and suicidal thoughts, fewer negative symptoms, single marital status and English as their first language. Rehabilitation service use was associated with greater anxiety symptoms, unemployment, younger age of illness onset, living alone and having no dependent children living at home. Last, outpatient/community services were more frequently used by younger people with good premorbid adjustment, hallucinations and a less severe course of illness.

CONCLUSIONS

Service utilisation patterns vary with the clinical and socio-demographic features of those who use them - inpatient and emergency service users being similar in such features and differing from users of other services. Comparison with the first national survey of psychosis revealed a significant decline in acute inpatient service use and a substantial increase in the use of outpatient/community and rehabilitation services over the past 10 years.

Comparative effectiveness of antipsychotic drugs in schizophrenia

Chlorpromazine, which was discovered in 1952, has an exhaustively characterized efficacy/safety profile comprising serious limitations: effectiveness in the field failing to match efficacy in trials, residual symptoms in 50% of patients, a 20% relapse rate in compliant patients, and worrisome extrapyramidal side effects, including tardive dyskinesia in 5% per year. Second-generation "atypical" antipsychotics bypass these effects by having less affinity for the dopamine D(2) receptor and affinities for other neuroreceptors. Clozapine, the lead atypical antipsychotic, was followed in the mid 1990s by risperidone, olanzapine, and quetiapine, which now account for over half of new antipsychotic prescriptions in North America, The debate over their relative efficacy involves the potential well-being of millions of schizophrenics and billions of dollars. Atypical antipsychotics are considerably more expensive; evidence for their superiority is highly variable and often inadequate, largely confined to short-term regulatory studies. Their effects on long-term outcome (particularly negative symptoms), relapse prevention, social and vocational functioning, suicide prevention and quality of life, and family and caregiver burden are largely unknown. The National institute of Mental Health's Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) project is a combined efficacy-effectiveness trial that aims to answer these questions in a broad range of patients with schizophrenia and Alzheimer's disease.

Role of the general practitioner in the care of patients recently discharged from the hospital after a first psychotic episode: influence of length of stay

OBJECTIVE

It is unclear to what extent general practitioners are involved in the postdischarge care of patients hospitalized for a first psychotic episode and whether this involvement is influenced by length of stay in the hospital. The objectives of this study were to describe the role of the general practitioner in providing postdischarge care to patients with first-episode psychosis in terms of frequency and type of consultation and the extent of collaboration with hospital-based specialist services and to determine whether decreasing length of stay was accompanied by a modification in this role.

METHOD

Six months after hospital discharge, a postal questionnaire was sent to the general practitioners of patients recruited to the French STEP cohort (Schizophrenie et son Traitement: une Evaluation de la Prize en charge), a prospective study of the clinical and social determinants of care pathways and prognosis for patients hospitalized for a first psychotic episode (DSM-IV criteria) in 5 services of the La Colombière Psychiatric Hospital, Montpellier, France. Length of stay in the hospital was dichotomized according to the median value of 35 days. Data collection took place from February 2008 to March 2009.

RESULTS

Of the 121 STEP patients, 65% (n=79) had a regular general practitioner. The general practitioners had been informed by the hospital of the admission of their patient in only 17.9% (7/39) of cases. Of the general practitioners, 78.3% (47/60) had seen the patient at least once since discharge, with a median number of visits standardized over 6 months of 0.86 (range, 0-8.6). General practitioners were better informed with regard to diagnosis, date of discharge, name of psychiatrist, treatment, and community follow-up at discharge for patients with a short length of stay in the hospital, who were also more likely than those with a long length of stay to be consulting for mental health problems.

CONCLUSIONS

Our findings suggest a low level of implication of general practitioners in providing postdischarge care to first-episode psychotic patients, irrespective of their length of hospital stay. Yet, the general practitioner has a role to play in coordinating and providing care for somatic health problems as well as psychiatric symptoms, specifically in the case of early discharge.

Needs-oriented discharge planning and monitoring for high utilisers of psychiatric services (NODPAM): design and methods

Background

Attempts to reduce high utilisation of psychiatric inpatient care by targeting the critical time of hospital discharge have been rare.

Methods

This paper presents design and methods of the study "Effectiveness and Cost-Effectiveness of Needs-Oriented Discharge Planning and Monitoring for High Utilisers of Psychiatric Services" (NODPAM), a multicentre RCT conducted in five psychiatric hospitals in Germany. Inclusion criteria are receipt of inpatient psychiatric care, adult age, diagnosis of schizophrenia or affective disorder, defined high utilisation of psychiatric care during two years prior to the current admission, and given informed consent. Consecutive recruitment started in April 2006. Since then, during a period of 18 months, comprehensive outcome data of 490 participants is being collected at baseline and during three follow-up measurement points.

The manualised intervention applies principles of needs-led care and focuses on the inpatient-outpatient transition. A trained intervention worker provides two intervention sessions: (a) Discharge planning: Just before discharge with the patient and responsible clinician at the inpatient service; (b) Monitoring: Three months after discharge with the patient and outpatient clinician. A written treatment plan is signed by all participants after each session.

Primary endpoints are whether participants in the intervention group will show fewer hospital days and readmissions to hospital. Secondary endpoints are better compliance with aftercare, better clinical outcome and quality of life, as well as cost-effectiveness and cost-utility.

Discussion

If a needs-oriented discharge planning and monitoring proves to be successful in this RCT, a tool will be at hand to improve patient outcome and reduce costs via harmonising fragmented mental health service provision.

Impact of risperidone long acting injection on resource utilization in psychiatric secondary care

Risperidone long acting injection (RLAI) is the only long acting atypical antipsychotic available in the UK. Its impact on NHS resource use has not been widely studied. This review of medical records was conducted to quantify the impact of RLAI on NHS psychiatric secondary care resource use, primarily in terms of episodes of inpatient hospital care 12 months before and 12 months after RLAI initiation. Data on number of hospitalizations and hospital bed days were collected retrospectively, from patient notes and hospital databases in four acute psychiatric units in the UK for all individuals with a diagnosis of schizophrenia or schizoaffective disorder who were prescribed RLAI more than 12 months previously. Data were collected on 100 individuals (58 male) with a mean age 40.8 years (range 19-70). The median duration of illness before RLAI initiation was 12 years (range six months to 43 years). There were 62 admissions in the 12 months pre-RLAI, falling to 22 admissions in the 12 months post-RLAI. Number of admissions, we argue, offer a more reliable indicator of the impact of treatment than total hospital bed days in this type of study. In this study there were 40 fewer admissions in the 12 months after RLAI was initiated compared with the previous 12 months. This is important as readmission is a good proxy measure of relapse, and adherence to medication is known to be a key factor in relapse prevention.

The European Schizophrenia Cohort (EuroSC): a naturalistic prognostic and economic study

BACKGROUND

Schizophrenia has a variety of clinical profiles, disabilities and outcomes requiring responsive management and the devotion of considerable resources. The primary objective of the European Schizophrenia Cohort (EuroSC) is to relate the types of treatment and methods of care to clinical outcome. Secondary objectives include the assessment of treatment needs in relation to outcome, the calculation of resource consumption associated with different methods of care, and the identification of prognostic factors.

METHOD

EuroSC is a naturalistic follow-up of a cohort of people aged 18 to 64 years, suffering from schizophrenia and in contact with secondary psychiatric services. The study was done in nine European centres, in France (N = 288), Germany (N = 618), and Britain (N = 302). Participants were interviewed at 6-monthly intervals for a total of 2 years. This initial paper describes the methods used and presents clinical and social baseline data.

RESULTS

The clinical and socio-demographic differences between patients from the different countries were small. However, patients from Britain were considerably more likely than their continental counterparts to have a history of homelessness, rooflessness or imprisonment, even when social and clinical differences between the samples were controlled.

CONCLUSIONS

The samples were largely similar in clinical terms. Thus, the social differences between the samples seem likely to be due more to the societal context and may reflect relatively benign situations in the continental locations of our study.

Premorbid, psychosocial and clinical predictors of the costs of schizophrenia and other psychoses

BACKGROUND

Predictors of the costs of psychosis have received insufficient research attention, particularly factors associated with indirect costs.

AIMS

To identify the predictors of direct mental health care costs and indirect or time-loss costs in psychotic disorders and to discuss their implications for future interventions.

METHOD

Structured interview data from the Low Prevalence Disorders Study (n=980) were used to examine predictors of the costs of psychosis in Australia. Estimates of annual costs per patient were derived from the perspectives of government and society. Hierarchical regressions were used to assess the contributions to costs of premorbid, psychosocial and clinical factors.

RESULTS

Schizophrenia involved greater costs than other psychotic disorders. Non-completion of high-school education and chronicity of illness course were predictive of higher costs across all categories, and some factors were linked primarily with mental health care costs (e.g. age at onset, current symptomatology) or indirect costs (e.g. male gender, overall disability).

CONCLUSIONS

Several concurrent strategies were recommended, including early intervention programmes and assertive evidence-based rehabilitation and supported employment programmes aimed at reducing disability. The cost-effectiveness of these approaches needs to be evaluated from the perspectives of both government and society.

Potential sampling and recruitment source impacts in schizophrenia research

Most schizophrenia research is undertaken on clinical samples in current contact with mental health services. It is not clear to what extent such samples are representative of the population of people with schizophrenia or whether they differ significantly, for example, from those who are being treated predominantly in primary care settings or who are recruited from non-clinical sources. Data from a volunteer schizophrenia research register and two recent Australian studies are reported, the Low Prevalence (psychotic) Disorders Study and an associated study of schizophrenia in general practice, in which all participants completed the same clinical assessment interview. Participants meeting criteria for schizophrenia or schizoaffective disorder were classified according to their source of recruitment: volunteer research register (n=128), general practice (n=123), community (n=236) or public inpatient (n=178) mental health services. Hierarchical discriminant function analyses revealed significant differences between these recruitment sources with respect to illness-onset factors, relationship and support factors, current functioning and course of illness. A severity/functioning gradient was observed across the four recruitment sources, possibly reflecting a spectrum of neurobiological impairment from good to poor prognosis. The implications of these findings for sampling strategies in schizophrenia research are discussed.

Comparisons between schizophrenia patients recruited from Australian general practices and public mental health services

OBJECTIVE

To examine differences between samples of schizophrenia patients recruited from general practice and public mental health services.

METHOD

Demographic, psychosocial, disability and 12-month service utilization data are reported from a multicentered survey of psychotic disorders and an associated study of schizophrenia in general practice. Patients with schizophrenia from three recruitment sources (in-patient, community services, general practice) were compared.

RESULTS

General practice patients had fewer symptoms, better functioning, lower service use, but comparable substance abuse, to patients from mental health services. They were generally similar to community mental health patients, with the exception of family support, premorbid work adjustment, negative symptoms and disability. Service contact models are also reported which demonstrate that general practitioners deal with schizophrenia patients across the range of illness severity and acuity.

CONCLUSION

Recruitment source impacts in schizophrenia research need to be more carefully considered during sample selection and better accounted for in the interpretation of results.

The goals and method of the Andalusian Case Register for Schizophrenia

BACKGROUND

Psychiatric case registers have been acknowledged as a valuable source of data, a long time ago. However, a growing interest exists in data on service utilization by patients belonging to groups with a related diagnosis to enable adequate planning of health resources.

AIMS

The aims of the Andalusian Case Register for Schizophrenia are to determine the prevalence of schizophrenia of those cared for by the public network of mental health services and to describe their pattern of care.

METHODS

Cases included on the Register are those persons resident in South Granada area with a diagnosis of schizophrenia and related disorders. The agencies which sent the information to the Register are all the mental health facilities in the catchment area.

CONCLUSIONS

The Register is a flexible instrument to use for epidemiological research and mental health care planning.

Improving the physical health of patients with schizophrenia: therapeutic nihilism or realism?

Schizophrenia is associated with a raised mortality due to both an increase in suicide and factors related to poor physical health. The increased rates of gastrointestinal, respiratory and cardiovascular disease in this population are likely to be due to high rates of smoking and obesity accompanied by a poor diet, lack of exercise and the side effects of medication. The evidence suggests that such risk factors in the schizophrenic population are largely ignored by the medical profession. Research to date has failed to address the health needs of this vulnerable population. Systematic research, with the aim of assessing the potential benefits of health improvement measures, should be a matter of priority.

Intellectual functioning and outcome of patients with severe psychotic illness randomised to intensive case management. Report from the UK700 trial

BACKGROUND

Little research has been carried out on the benefits of intensive case management (ICM) for people with borderline IQ and severe mental illness.

AIMS

To compare outcome and costs of care of patients with severe psychotic illness with borderline IQ to patients of normal IQ and to assess whether ICM is more beneficial for the former than for the latter.

METHOD

The study utilises data from the UK700 multi-centre randomised controlled trial of case management. The main outcome measure was the number of days spent in hospital for psychiatric reasons. Secondary outcomes were costs of care and clinical outcome.

RESULTS

ICM was significantly more beneficial for borderline-IQ patients than those of normal IQ in terms of reductions in days spent in hospital, hospital admissions, total costs and needs and increased satisfaction.

CONCLUSIONS

ICM appears to be a cost-effective strategy for a subgroup of patients with severe psychosis with cognitive deficits.

Costs and characteristics of heavy inpatient service users in outer London

"Heavy users" is a new term often used to describe those who occupy a disproportionate number of psychiatric beds. In this study we identified the heaviest 10% (193) inpatient service users in one London borough over a 6 year period and compared these with a control group of 400 ordinary inpatient users. A weighting index was used to combine frequency of admission with duration. Heavy users were diagnostically and demographically similar to ordinary inpatient service users and only differed by their extensive use of services, about 3 times more than ordinary users in terms of health care costs, during the measured year. Their heavy use mainly depended on occupying hospital beds, and their use of outpatient, day patient and community services was relatively light.

Can involuntary outpatient commitment reduce hospital recidivism?: Findings from a randomized trial with severely mentally ill individuals

OBJECTIVE

The goal of this study was to evaluate the effectiveness of involuntary outpatient commitment in reducing rehospitalizations among individuals with severe mental illnesses.

METHOD

Subjects who were hospitalized involuntarily were randomly assigned to be released (N = 135) or to continue under outpatient commitment (N = 129) after hospital discharge and followed for 1 year. Each subject received case management services plus additional outpatient treatment. Outpatient treatment and hospital use data were collected.

RESULTS

In bivariate analyses, the control and outpatient commitment groups did not differ significantly in hospital outcomes. However, subjects who underwent sustained periods of outpatient commitment beyond that of the initial court order had approximately 57% fewer readmissions and 20 fewer hospital days than control subjects. Sustained outpatient commitment was shown to be particularly effective for individuals with nonaffective psychotic disorders, reducing hospital readmissions approximately 72% and requiring 28 fewer hospital days. In repeated measures multivariable analyses, the outpatient commitment group had significantly better hospital outcomes, even without considering the total length of court-ordered outpatient commitments. However, in subsequent repeated measures analyses examining the role of outpatient treatment among psychotically disordered individuals, it was also found that sustained outpatient commitment reduced hospital readmissions only when combined with a higher intensity of outpatient treatment.

CONCLUSIONS

Outpatient commitment can work to reduce hospital readmissions and total hospital days when court orders are sustained and combined with intensive treatment, particularly for individuals with psychotic disorders. This use of outpatient commitment is not a substitute for intensive treatment; it requires a substantial commitment of treatment resources to be effective.

Outcomes focused service delivery: developing an academic-management partnership

OBJECTIVE

Current mental health policies emphasise the need for services to be integrated and to develop outcomes-based evaluation systems. An overview of the challenges faced by service managers and clinical academics who develop the appropriate financial, personnel and academic infrastructure for these tasks is presented.

METHOD

By drawing on experiences within the St George Service and references to other services, we propose a model for a successful partnership between the academic and management components of a district service.

RESULTS

Major logistic impediments to the development of a partnership are identified, although the long-term scientific and service delivery benefits are highlighted. Key areas within both academic practice and managerial approaches requiring transformation are discussed.

CONCLUSIONS

A successful long-term partnership between management and an academic department within a district service may provide the opportunity for rapid progress in population-based service evaluation and health outcomes research.
