The rise of assertive community interventions in South Africa: a randomized control trial assessing the impact of a modified assertive intervention on readmission rates; a three year follow-up

Schizophrenia and schizoaffective disorder: Length of stay and associated factors

Background

Patients with schizophrenia and schizoaffective disorder often require longer admissions.

Aim

To explore length of stay (LOS) and associated factors of patients with schizophrenia and schizoaffective disorder, admitted to a public sector specialised psychiatric hospital, over a 4-year period.

Setting

The study was conducted at Tara Hospital in Johannesburg.

Methods

A retrospective record review of 367 adult schizophrenia and schizoaffective disorder patients admitted between 01 January 2015 and 31 December 2018. Average LOS was calculated and the proportion of short-stay (< 30 days), medium-stay (31-90 days) and long-stay (> 90 days) admissions determined. Sociodemographic, clinical and admission outcome data were collected and analysed from a randomly selected subset of patients in each LOS category.

Results

Mean LOS was 128 days (median 87, interquartile range [IQR] 49-164, range 0-755 days). A significantly greater proportion had long-stay admissions (p < 0.001). Male gender (p = 0.018), being unmarried (p = 0.006), treatment resistant (p < 0.001) and on clozapine (p = 0.009) were factors found to have a significant association with long-stay admissions. Rates of unemployment (> 80%), comorbid substance use disorders (> 40%), medical illnesses (> 40%), antipsychotic polypharmacy (> 40%) and readmissions (> 80%) were high. Most (> 80%) were discharged.

Conclusion

Long-stay admissions were frequently required for patients with schizophrenia and schizoaffective disorder admitted to Tara Hospital.

Contribution

This study highlights factors associated with long-stay admissions in patients with schizophrenia and schizoaffective disorder. More research is needed into whether increased access to community-based services, such as residential and daycare facilities, outpatient substance rehabilitation programmes and dual diagnosis clinics, could translate into shorter admissions, less frequent relapses and improved outcomes in this population.

Madison to Manipal: A narrative review of modified assertive community treatment programs

BACKGROUND

Assertive community treatment (ACT) is a multidisciplinary, team-based approach providing comprehensive individualized care for the patients with various mental illness, has been adapted variably across the world in terms of patient-staff ratio, selection of patients, the pattern of service delivery and frequency of contact. We aim to review the extant literature on the modifications of ACT programs for severe mental disorders and their effectiveness.

METHODS

Studies on modified ACT approaches for mental illnesses were searched in multiple databases. We adopted a rapid appraisal approach. The searches were restricted to articles published in English. We appraised the fidelity assessment of the ACT studies wherever available. In addition, we assessed the study quality using a grading tool based on ten practice components of ACT.

RESULTS

We found 23 reports (10 RCTs and 13 non-controlled studies) on modified ACT. The extant literature on modified ACT programs is heterogeneous. The modifications in ACT included changes in patient-to-staff ratio, team composition, service hours, and interventions carried out. Most controlled studies were conducted in high-income settings and had inconsistent outcome, possibly due to the comprehensive nature of the 'usual care.' In contrast, modified ACT services from low and middle-income countries reduced hospitalization rates and improved treatment adherence.

CONCLUSIONS

Modifications in ACT programs were done to cater to specific subpopulation and the changes in program structure to suit the resources and setting. The outcome of modified ACT appears heterogenous, though the findings from low and middle-income countries are promising.

Effectiveness of Community-Based Rehabilitation Interventions on Symptoms and Functioning for People with Schizophrenia: A Systematic Review and Meta-Analysis

Schizophrenia is a serious mental illness that imposes huge burden of illness on the society. We aimed to conduct a meta-analytic and systematic review of literature on the effectiveness of community-based rehabilitation interventions on symptoms and functioning for people with schizophrenia. The PubMed, Embase, the Cochrane Library, Web of Science, and CINAHL databases were searched through April 16 and 17, 2021, including clinical trial registries and previous Cochrane reviews. We included 24 randomized controlled trials in this review. The content of interventions varied from single-faceted rehabilitation intervention or cognitive retraining, to multi-component rehabilitation interventions or case management. Among 20 studies that reported effects of community-based rehabilitation interventions on symptoms, the pooled SMDs across all interventions was 0.94 (95% CI = 0.11, 1.76; P < 0.001; I2 = 99.1%; n = 3694), representing a strong effect. 21 included studies showed that community-based rehabilitation interventions also had beneficial impacts on functioning (SMD = 1.65; 95% CI = 0.88, 2.43; P < 0.001; I2 = 98.9%; n = 3734). Overall quality of evidence was moderate with a high level of heterogeneity. Community-based rehabilitation interventions have positive effectiveness in improving patients' symptoms and functioning. Community-based rehabilitation interventions should therefore be provided as an adjuvant service in addition to facility-based care for people with schizophrenia.

Impact of completing a psychosocial rehabilitation programme on inpatient service utilisation in South Africa

Background

Deinstitutionalisation refers to the process of transferring most of the psychiatric care provision from inpatient state-run institutions to community-based care. However, it has proven difficult to implement and failed to reach its desired targets. New Beginnings (NB) is a transitional care facility that facilitates the transition from in- to outpatient care. To date, no data exist as to whether the intervention provided at NB is effective in reducing psychiatric readmissions.

Aim

To determine if completing a psychosocial rehabilitation (PSR) programme reduces acute inpatient service utilisation and if this is influenced by sociodemographic or clinic factors.

Setting

New Beginnings transitional care facility in South Africa.

Methods

A record review of all NB admissions between January 2011 and December 2015. Demographic and clinical data were collected, including readmissions and days-in-hospital (DIH), 36 months pre- and postindex admission. Patients were divided into a completer group (CG) and a noncompleter group (NCG) for the eight-week PSR programme, and comparative statistical analysis was performed.

Results

Completion of the 8-week voluntary inpatient PSR programme led to a significant decrease (p = 0.017) (CG vs. NCG) in DIH during the 36-month period postindex admission. In addition, both groups showed significantly decreased (p < 0.001) DIH postindex in comparison to pre-index admission.

Conclusions

This study’s findings support that transitional care facilities offering an inpatient PSR programme may reduce inpatient service utilisation for all attendees but especially for those who complete the program. This highlights the need for such facilities that offer interventions tailored for patients with mental illness.

Contribution

This is the first local study highlighting the potentially important role transitional care facilities could play in reducing readmissions.

Modified assertive community treatment program for patients with schizophrenia: Effectiveness and perspectives of service consumers from a South Indian setting

BACKGROUND

Schizophrenia is a disabling mental illness. Antipsychotic treatment in conjunction with comprehensive psychosocial rehabilitation services is essential in promoting functional recovery. Assertive Community Treatment (ACT) is an evidence-based approach in promoting recovery in schizophrenia. The evidence for the effectiveness and feasibility of such community-based assertive interventions in low and middle-income countries is limited.

AIM

To evaluate the effectiveness of modified assertive community treatment in a South Indian setting and evaluate the perspectives of patients and caregivers who participated in the program.

METHODOLOGY

Socio-demographic details, illness characteristics, course of the illness including the number of relapses and hospitalization, adherence level at baseline, the scores on the Social and Occupational Functioning Assessment Scale (SOFAS), and Global disability score on Indian Disability Evaluation and Assessment Scale (IDEAS) were compared before and after the initiation of the M-CAT program using retrospective file review. The perspectives of the clients were assessed using a 6-item questionnaire.

RESULTS

Ten patients (six male and four female) with a diagnosis of schizophrenia were under the Manipal Assertive Community Treatment (M-ACT) program for a median duration of 3 years (IQR 1.25) participated in the study. There was a significant improvement in the overall level of functioning, medication adherence, relapse rates, and disability after the enrolment into the program. The majority of the respondents had a positive attitude towards the M-ACT program.

CONCLUSION

Assertive community interventions with suitable modifications for local resource-limited conditions may be an effective option in promoting functional recovery in Schizophrenia.

Descriptive outcomes for a cohort of high-frequency psychiatric service users in the Western Cape, South Africa after 10 years

Background: Assertive community treatment (ACT) is an intervention implemented to manage the effects of deinstitutionalisation. South African studies have reported decreased admissions at 12 and 36 months when a modified ACT intervention is compared with standard care. However, costs associated with the intervention have raised the question of its feasibility in developing countries.Aim: This study aimed to describe the long-term demographic and clinical outcomes of a group of psychiatric high-frequency users (HFUs) included in the first South African ACT study.Setting: Stikland Psychiatric Hospital, Cape Town, South Africa.Methods: Data from 55 HFUs participating in the first South African ACT trial, including both the intervention and control groups, were retrospectively reviewed 10 years after the patients’ inclusion.Results: Of the 55 HFUs initially included, nine remained in the formal ACT programme whilst 16 received standard care over the full 10 years. Five patients died and two were admitted to long-term wards. The mean number of admissions was 3.73 and the mean number of admission days was 261.11 over the 10 years. Twelve patients were never re-admitted; of these, nine came from the original study intervention group.Conclusions: This was the first study looking at the long-term outcomes of a group of psychiatric HFUs in an under-resourced setting receiving either a modified ACT intervention or standard outpatient care. Reflecting broadly on the group, there were a larger number of patients in the original ACT group who had no re-admissions and a comparatively higher utilisation of available services during the 10-year follow-up period.

The Role of Medical Comorbidity in the Rapid Psychiatric Readmission of Patients With Schizophrenia-spectrum Disorders

OBJECTIVE

Inpatient admissions are common for individuals with schizophrenia-spectrum disorders, and difficulty transitioning from the hospital to the community results in these individuals being at high risk for hospital readmissions. Thus, psychotic disorders account for high rates of rapid readmission within 30 days of discharge. Increasing evidence highlights the role of comorbid medical conditions, such as circulatory and metabolic problems, in contributing to early readmission rates for these patients. This study examined the specific role of circulatory and metabolic problems in predicting psychiatric rehospitalizations while accounting for other medical conditions, psychiatric comorbidities, and preadmission medications.

METHODS

The electronic medical records of 752 patients admitted to a psychiatric hospital were examined, with patients classified as having readmission within 30 days of their index hospitalization (n=79) or no readmission within 30 days (n=673). The 2 groups were compared on multiple variables in univariate and multivariate analyses.

RESULTS

Male sex [odds ratio (OR)=2.02, P=0.019)], disability status (OR=1.96, P=0.027), and presence of a circulatory (but not a metabolic) condition (OR=3.43, P=0.003) were associated with significantly increased odds of being rehospitalized within 30 days, even when accounting for additional predictors, including age, substance use disorder, race, and other medical conditions.

CONCLUSIONS

These findings highlight the importance of considering circulatory, in addition to metabolic disorders, during inpatient stays. This comorbidity pattern may signify a subset of individuals with schizophrenia-spectrum disorders requiring more comprehensive discharge planning and support after an inpatient hospitalization to prevent rapid rehospitalization.

Effect of community mental health care programs in Australia: a systematic review

Although numerous studies have examined the effects of community-based mental health care programs in Australia, no synthesis of this literature exists. This systematic review of peer-reviewed and grey literature described the types of community-based mental health care programs delivered and evaluated in Australia in the past 20 years, and evaluated their impact in improving outcomes for those with a serious mental illness (SMI). Articles were included if they evaluated the extent to which the programs delivered in Australia improved individual outcomes, including hospitalisations, psychiatric symptoms, substance misuse or psychosocial outcomes, for individuals with an SMI. Forty studies were included. Community-based mental health care programs were categorised into three types: case management (n=23), therapeutic (n=11) and lifestyle (n=6). Therapeutic programs were most effective in reducing psychiatric symptoms. Case management approaches yielded significant improvements in psychosocial outcomes. Lifestyle programs were inconclusive in improving individual outcomes. This review provides support for the implementation of community-based mental health care programs that are informed by both therapeutic and case management principles. A multidisciplinary team that can facilitate the provision of therapeutic and psychosocial support may be most beneficial for those with an SMI within the Australian community.

Demographic and clinical profile of patients utilising a transitional care intervention in the Western Cape, South Africa

Background

The World Health Organization’s action plan for 2020 has identified the need for service-based data to motivate for more appropriate community-based services. To date, there is no published data from step-up or step-down facilities in South Africa.

Aim

To describe the demographic and clinical profile of all patients admitted to New Beginnings between 01 January 2011 and 31 December 2015.

Setting

New Beginnings is an intermediary care facility focused on psychosocial rehabilitation and accommodates 40 patients in a step-up or step-down setting.

Methods

In this retrospective audit, we reviewed the medical records of all patients (N = 730) admitted to New Beginnings between 01 January 2011 and 31 December 2015.

Results

Most admissions were male (n = 600; 82.2%), unmarried (92.1%) and unemployed (92.7%) patients with a mean age of 28 years. Only 20.7% had completed their schooling and 37.9% were receiving a disability grant. Most patients lived in the Cape Town Metro area (89%) with their families (94.7%), and 75.6% had no children. Schizophrenia (53.7%) was the most common primary psychiatric diagnosis, and most patients were on a combination of oral and depot treatment (46.8%). Illicit substances were used by 75.9% of patients with 30% using both cannabis and methamphetamine. Most patients (74.9%) had only one admission to New Beginnings.

Conclusions

These baseline data could inform improved service delivery. Further research is needed to evaluate the success of New Beginnings and highlight the need for more of these facilities in the Western Cape and across South Africa.

Risk factors for readmission among a cohort of psychiatric inpatients in Lilongwe, Malawi

Objectives: Inpatient psychiatric capacity is limited in Malawi and no published studies have assessed psychiatric readmissions there. Information about factors associated with readmission may help guide strategies to reduce readmission rates and keep patients stabilised in the community. Our goal was to determine factors associated with readmission among a cohort of psychiatric inpatients in Lilongwe, Malawi.Methods: We conducted a retrospective chart review of all patients admitted to an inpatient psychiatric unit in Lilongwe, Malawi from January 1 to December 31, 2011. We used logistic regression to test for associations between readmissions during the study period and patient variables.Results: 419 patients were hospitalised during the study period. Twenty-nine patients (6.9%) were readmitted at least once during the study period. Readmission was associated only with intentional medication non-adherence at home (aOR: 3.33, p = 0.02).Conclusions: Intentional medication non-adherence is a potentially modifiable behaviour associated with psychiatric readmission. Efforts to improve medication adherence among patients following hospital discharge may help decrease the risk of readmission.KEY POINTSThe prevalence of readmission among psychiatric inpatients in Lilongwe, Malawi was 6.9% during the 1-year study period.Readmission was associated with intentional medication non-adherence at home.Future research efforts in Malawi should focus on improving medication adherence among psychiatric patients in the community to help decrease rates of readmission.

Evidence and gap map of studies assessing the effectiveness of interventions for people with disabilities in low-and middle-income countries

Background

There are approximately 1 billion people in the world with some form of disability. This corresponds to approximately 15% of the world's population (World Report on Disability, 2011). The majority of people with disabilities (80%) live in low- and middle-income countries (LMICs), where disability has been shown to disproportionately affect the most disadvantaged sector of the population. Decision makers need to know what works, and what does not, to best invest limited resources aimed at improving the well-being of people with disabilities in LMICs. Systematic reviews and impact evaluations help answer this question. Improving the availability of existing evidence will help stakeholders to draw on current knowledge and to understand where new research investments can guide decision-making on appropriate use of resources. Evidence and gap maps (EGMs) contribute by showing what evidence there is, and supporting the prioritization of global evidence synthesis needs and primary data collection.

Objectives

The aim of this EGM is to identify, map and describe existing evidence of effectiveness studies and highlight gaps in evidence base for people with disabilities in LMICs. The map helps identify priority evidence gaps for systematic reviews and impact evaluations.

Methods

The EGM included impact evaluation and systematic reviews assessing the effect of interventions for people with disabilities and their families/carers. These interventions were categorized across the five components of community-based rehabilitation matrix; health, education, livelihood, social and empowerment. Included studies looked at outcomes such as, health, education, livelihoods, social inclusion and empowerment, and were published for LMICs from 2000 onwards until January 2018. The searches were conducted between February and March 2018. The EGM is presented as a matrix in which the rows are intervention categories (e.g., health) and subcategories (e.g., rehabilitation) and the column outcome domains (e.g., health) and subdomains (e.g., immunization). Each cell lists the studies for that intervention for those outcomes, with links to the available studies. Included studies were therefore mapped according to intervention and outcomes assessed and additional filters as region, population and study design were also coded. Critical appraisal of included systematic review was done using A Measurement Tool to Assess Systematic Reviews' rating scale. We also quality-rated the impact evaluation using a quality assessment tool based on various approaches to risk of bias assessment.

Results

The map includes 166 studies, of which 59 are systematic reviews and 107 impact evaluation. The included impact evaluation are predominantly quasiexperimental studies (47%). The numbers of studies published each year have increased steadily from the year 2000, with the largest number published in 2017.The studies are unevenly distributed across intervention areas. Health is the most heavily populated area of the map. A total of 118 studies of the 166 studies concern health interventions. Education is next most heavily populated with 40 studies in the education intervention/outcome sector. There are relatively few studies for livelihoods and social, and virtually none for empowerment. The most frequent outcome measures are health-related, including mental health and cognitive development (n = 93), rehabilitation (n = 32), mortality and morbidity (n = 23) and health check-up (n = 15). Very few studies measured access to assistive devices, nutrition and immunization. Over half (n = 49) the impact evaluation come from upper-middle income countries. There are also geographic gaps, most notably for low income countries (n = 9) and lower-middle income countries (n = 34). There is a fair amount of evidence from South Asia (n = 73) and Sub-Saharan Africa (n = 51). There is a significant gap with respect to study quality, especially with respect to impact evaluation. There appears to be a gap between the framing of the research, which is mostly within the medical model and not using the social model of disability.

Conclusion

Investing in interventions to improve well-being of people with disabilities will be critical to achieving the 2030 agenda for sustainable development goals. The EGM summarized here provides a starting point for researchers, decision makers and programme managers to access the available research evidence on the effectiveness of interventions for people with disabilities in LMICs in order to guide policy and programme activity, and encourage a more strategic, policy-oriented approach to setting the future research agenda.

Effectiveness of an Assertive Community Treatment program for people with severe schizophrenia in mainland China - a 12-month randomized controlled trial

BACKGROUND

Assertive Community Treatment (ACT) is an evidence-based treatment program for people with severe mental illness developed in high-income countries. We report the first randomized controlled trial of ACT in mainland China.

METHODS

Sixty outpatients with schizophrenia with severe functional impairments or frequent hospitalizations were randomly assigned to ACT (n = 30) or standard community treatment (n = 30). The severity of symptoms and level of social functioning were assessed at baseline and every 3 months during the 1-year study. The primary outcome was the duration of hospital readmission. Secondary outcomes included a pre-post change in symptom severity, the rates of symptom relapse and gainful employment, social and occupational functioning, and quality of life of family caregivers.

RESULTS

Based on a modified intention-to-treat analysis, the outcomes for ACT were significantly better than those of standard community treatment. ACT patients were less likely to be readmitted [3.3% (1/30) v. 25.0% (7/28), Fisher's exact test p = 0.023], had a shorter mean readmission time [2.4 (13.3) v. 30.7 (66.9) days], were less likely to relapse [6.7% (2/30) v. 28.6% (8/28), Fisher's exact test p = 0.038], and had shorter mean time in relapse [3.5 (14.6) v. 34.4 (70.6) days]. The ACT group also had significantly longer times re-employed and greater symptomatic improvement and their caregivers experienced a greater improvement in their quality of life.

CONCLUSION

Our results show that culturally adapted ACT is both feasible and effective for individuals with severe schizophrenia in urban China. Replication studies with larger samples and longer duration of follow up are warranted.

The Role of Communities in Mental Health Care in Low- and Middle-Income Countries: A Meta-Review of Components and Competencies

Community-based mental health services are emphasized in the World Health Organization’s Mental Health Action Plan, the World Bank’s Disease Control Priorities, and the Action Plan of the World Psychiatric Association. There is increasing evidence for effectiveness of mental health interventions delivered by non-specialists in community platforms in low- and middle-income countries (LMIC). However, the role of community components has yet to be summarized. Our objective was to map community interventions in LMIC, identify competencies for community-based providers, and highlight research gaps. Using a review-of-reviews strategy, we identified 23 reviews for the narrative synthesis. Motivations to employ community components included greater accessibility and acceptability compared to healthcare facilities, greater clinical effectiveness through ongoing contact and use of trusted local providers, family involvement, and economic benefits. Locations included homes, schools, and refugee camps, as well as technology-aided delivery. Activities included awareness raising, psychoeducation, skills training, rehabilitation, and psychological treatments. There was substantial variation in the degree to which community components were integrated with primary care services. Addressing gaps in current practice will require assuring collaboration with service users, utilizing implementation science methods, creating tools to facilitate community services and evaluate competencies of providers, and developing standardized reporting for community-based programs.

Brief Report: A Randomized Control Trial Assessing the Influence of a Telephone-based Intervention on Readmissions for Patients with Severe Mental Illness in a Developing Country

Whilst comprehensive post-discharge interventions have been successful in reducing readmissions in our setting, they are possibly not sustainable due to limited resources. We assessed the impact of a more cost-effective telephone-based intervention on readmissions in a developing country over 12 months. 100 patients with severe mental illness were randomized to facilitated care or treatment as usual. All were interviewed prior to discharge and after 12 months. Facilitated care consisted of structured telephonic interviews and motivational support to patients and families. At 12 months no significant differences in either readmissions (p = 0.10) or days in hospital (p = 0.44) could be demonstrated. Substance use was high (64%), particularly methamphetamine (44%) in both groups. The intervention did not have any impact on inpatient usage in our setting. Though this study was limited by its small sample size, the results indicated that affordable post-discharge services may not be comprehensive enough to reduce readmission rates and would have to be tailored to the distinct population of dual diagnosis patients identified in this study.

Community-based psychosocial interventions for people with schizophrenia in low and middle-income countries: systematic review and meta-analysis

BACKGROUND

There is consensus that the treatment of schizophrenia should combine anti-psychotic medication and psychosocial interventions in order to address complex social, economic and health needs. It is recommended that family therapy or support; community-based rehabilitation; and/or self-help and support groups should be provided for people with schizophrenia in low and middle-income countries. The effectiveness of community-based psychosocial interventions in these settings is unclear.

METHODS

Studies evaluating community-based psychosocial interventions for people with schizophrenia were identified through database searching up to April 2016. Randomised controlled trials were included if they compared the intervention group with a control group receiving treatment as usual including medication. Only studies set in low and middle-income countries were included. Random effects meta-analyses were performed separately for each intervention type.

RESULTS

Eleven randomised controlled trials in five middle-income countries were identified, with a total of 1580 participants. The content of included interventions varied from single-faceted psychoeducational interventions, to multi-component rehabilitation-focused interventions, to case management interventions. A third of the included studies did not incorporate any community involvement in the intervention. The quality of evidence was often low. Amongst the seven studies that reported on symptom severity up to 18 months post intervention, the pooled standardised mean difference (SMD) across all intervention types was 0.95 (95% CI 0.28, 1.61; P 0.005; I 2 = 95%; n = 862), representing a strong effect. A strong effect on symptom severity remained after excluding two studies with a high risk of bias (SMD 0.80; 95% CI 0.07, 1.53; P 0.03; I 2 = 94%; n = 676). Community-based psychosocial interventions may also have beneficial impacts on functioning (SMD 1.12; 95% CI 0.25, 2.00; P 0.01; I 2 = 94%; n = 511) and reducing hospital readmissions (SMD 0.68; 95% CI 0.27, 1.09; P 0.001; I2 = 33%; n = 167).

CONCLUSION

The limited evidence from low and middle-income countries supports the feasibility and effectiveness of community-based psychosocial interventions for schizophrenia, even in the absence of community mobilisation. Community-based psychosocial interventions should therefore be provided in these settings as an adjuvant service in addition to facility-based care for people with schizophrenia.

Next steps for meeting the needs of people with severe mental illness in low- and middle-income countries

The explicit inclusion of mental health within the Sustainable Development Goals is a welcome development, borne out of powerful advocacy using public health, economic and human rights arguments. As funding comes on line for scale-up of evidence-based mental health care by task-sharing with primary care, it is time to take stock about care for people affected by severe mental illness (SMI). The existing evidence base for task shared care for SMI provides an imperative to get started, but is skewed towards relatively more affluent and urban populations in middle-income countries where specialist mental health professionals provide most of the care. Randomised, controlled trials and rigorous implementation research on task shared service models are underway which will go some way to improving understanding of the quality, safety, effectiveness and acceptability of more widely generalisable care for people with SMI. A sub-group of people with SMI have more complex and long-term needs for care, with a high risk of homelessness, imprisonment and human rights violations as family and social supports become overwhelmed. Case studies from non-governmental organisations provide examples of holistic approaches to rehabilitation, recovery and empowerment of people with SMI, but rigorous comparative studies are needed to identify the most efficient, effective and scalable approaches to care. Health system constraints are emerging as the over-riding barriers to successful task-sharing, highlighting a need to develop and evaluate chronic care models for people with SMI that succeed in reducing premature mortality, improving wellbeing and achieving better social outcomes. Addressing these evidence gaps is essential if task-sharing mental health care is going to deliver on its promise of promoting recovery for the full range of people affected by SMI.

Intensive case management for severe mental illness

BACKGROUND

Intensive Case Management (ICM) is a community-based package of care aiming to provide long-term care for severely mentally ill people who do not require immediate admission. Intensive Case Management evolved from two original community models of care, Assertive Community Treatment (ACT) and Case Management (CM), where ICM emphasises the importance of small caseload (fewer than 20) and high-intensity input.

OBJECTIVES

To assess the effects of ICM as a means of caring for severely mentally ill people in the community in comparison with non-ICM (caseload greater than 20) and with standard community care. We did not distinguish between models of ICM. In addition, to assess whether the effect of ICM on hospitalisation (mean number of days per month in hospital) is influenced by the intervention's fidelity to the ACT model and by the rate of hospital use in the setting where the trial was conducted (baseline level of hospital use).

SEARCH METHODS

We searched the Cochrane Schizophrenia Group's Trials Register (last update search 10 April 2015).

SELECTION CRITERIA

All relevant randomised clinical trials focusing on people with severe mental illness, aged 18 to 65 years and treated in the community care setting, where ICM is compared to non-ICM or standard care.

DATA COLLECTION AND ANALYSIS

At least two review authors independently selected trials, assessed quality, and extracted data. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated mean difference (MD) between groups and its 95% CI. We employed a random-effects model for analyses.We performed a random-effects meta-regression analysis to examine the association of the intervention's fidelity to the ACT model and the rate of hospital use in the setting where the trial was conducted with the treatment effect. We assessed overall quality for clinically important outcomes using the GRADE approach and investigated possible risk of bias within included trials.

MAIN RESULTS

The 2016 update included two more studies (n = 196) and more publications with additional data for four already included studies. The updated review therefore includes 7524 participants from 40 randomised controlled trials (RCTs). We found data relevant to two comparisons: ICM versus standard care, and ICM versus non-ICM. The majority of studies had a high risk of selective reporting. No studies provided data for relapse or important improvement in mental state.1. ICM versus standard careWhen ICM was compared with standard care for the outcome service use, ICM slightly reduced the number of days in hospital per month (n = 3595, 24 RCTs, MD -0.86, 95% CI -1.37 to -0.34,low-quality evidence). Similarly, for the outcome global state, ICM reduced the number of people leaving the trial early (n = 1798, 13 RCTs, RR 0.68, 95% CI 0.58 to 0.79, low-quality evidence). For the outcome adverse events, the evidence showed that ICM may make little or no difference in reducing death by suicide (n = 1456, 9 RCTs, RR 0.68, 95% CI 0.31 to 1.51, low-quality evidence). In addition, for the outcome social functioning, there was uncertainty about the effect of ICM on unemployment due to very low-quality evidence (n = 1129, 4 RCTs, RR 0.70, 95% CI 0.49 to 1.0, very low-quality evidence).2. ICM versus non-ICMWhen ICM was compared with non-ICM for the outcome service use, there was moderate-quality evidence that ICM probably makes little or no difference in the average number of days in hospital per month (n = 2220, 21 RCTs, MD -0.08, 95% CI -0.37 to 0.21, moderate-quality evidence) or in the average number of admissions (n = 678, 1 RCT, MD -0.18, 95% CI -0.41 to 0.05, moderate-quality evidence) compared to non-ICM. Similarly, the results showed that ICM may reduce the number of participants leaving the intervention early (n = 1970, 7 RCTs, RR 0.70, 95% CI 0.52 to 0.95,low-quality evidence) and that ICM may make little or no difference in reducing death by suicide (n = 1152, 3 RCTs, RR 0.88, 95% CI 0.27 to 2.84, low-quality evidence). Finally, for the outcome social functioning, there was uncertainty about the effect of ICM on unemployment as compared to non-ICM (n = 73, 1 RCT, RR 1.46, 95% CI 0.45 to 4.74, very low-quality evidence).3. Fidelity to ACTWithin the meta-regression we found that i.) the more ICM is adherent to the ACT model, the better it is at decreasing time in hospital ('organisation fidelity' variable coefficient -0.36, 95% CI -0.66 to -0.07); and ii.) the higher the baseline hospital use in the population, the better ICM is at decreasing time in hospital ('baseline hospital use' variable coefficient -0.20, 95% CI -0.32 to -0.10). Combining both these variables within the model, 'organisation fidelity' is no longer significant, but the 'baseline hospital use' result still significantly influences time in hospital (regression coefficient -0.18, 95% CI -0.29 to -0.07, P = 0.0027).

AUTHORS' CONCLUSIONS

Based on very low- to moderate-quality evidence, ICM is effective in ameliorating many outcomes relevant to people with severe mental illness. Compared to standard care, ICM may reduce hospitalisation and increase retention in care. It also globally improved social functioning, although ICM's effect on mental state and quality of life remains unclear. Intensive Case Management is at least valuable to people with severe mental illnesses in the subgroup of those with a high level of hospitalisation (about four days per month in past two years). Intensive Case Management models with high fidelity to the original team organisation of ACT model were more effective at reducing time in hospital.However, it is unclear what overall gain ICM provides on top of a less formal non-ICM approach.We do not think that more trials comparing current ICM with standard care or non-ICM are justified, however we currently know of no review comparing non-ICM with standard care, and this should be undertaken.

Beyond symptom management: Family relations, unmet needs of persons living with severe mental illnesses, and potential implications for social work in South Africa

This study examined the quality of family relationships and its associations with the severity of unmet needs of individuals admitted to a tertiary psychiatric hospital in South Africa. The quality of family relations and perceived unmet needs were assessed using the Lehman Quality of Life Interview and Camberwell Assessment of Needs, respectively. The results show that higher total unmet needs were associated with lower quality of family relations. The main areas of serious unmet needs included accessing government benefits and information, and establishing social relations. The results have implications for hospital-based social workers beyond managing psychiatric symptoms in South Africa.

Treatment of adult patients with schizophrenia and complex mental health needs - A national clinical guideline

BACKGROUND AND AIM

The Danish Health and Medicines Authority assembled a group of experts to develop a national clinical guideline for patients with schizophrenia and complex mental health needs. Within this context, ten explicit review questions were formulated, covering several identified key issues.

METHODS

Systematic literature searches were performed stepwise for each review question to identify relevant guidelines, systematic reviews/meta-analyses, and randomized controlled trials. The quality of the body of evidence for each review question was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Clinical recommendations were developed on the basis of the evidence, assessment of the risk-benefit ratio, and perceived patient preferences.

RESULTS

Based on the identified evidence, a guideline development group (GDG) recommended that the following interventions should be offered routinely: antipsychotic maintenance therapy, family intervention and assertive community treatment. The following interventions should be considered: long-acting injectable antipsychotics, neurocognitive training, social cognitive training, cognitive behavioural therapy for persistent positive and/or negative symptoms, and the combination of cognitive behavioural therapy and motivational interviewing for cannabis and/or central stimulant abuse. SSRI or SNRI add-on treatment for persistent negative symptoms should be used only cautiously. Where no evidence was available, the GDG agreed on a good practice recommendation.

CONCLUSIONS

The implementation of this guideline in daily clinical practice can facilitate good treatment outcomes within the population of patients with schizophrenia and complex mental health needs. The guideline does not cover all available interventions and should be used in conjunction with other relevant guidelines.

Perceptions of psychosocial disability amongst psychiatric service users and caregivers in South Africa

BACKGROUND

In many parts of South Africa there is little support for people with psychosocial disability caused by schizophrenia, beyond provision of psychotropic medications. Appropriate community-based psychosocial rehabilitation interventions are a crucial element of mental health service development.

OBJECTIVES

This study aimed to use an explanatory model of illness framework to document experiences of illness, disability and recovery amongst service users with schizophrenia and their caregivers in a poorly resourced area in the North West Province. Data were used to provide recommendations for a contextually appropriate non-specialist facilitated group psychosocial rehabilitation intervention.

METHOD

Eighteen in-depth individual interviews were conducted: nine with schizophrenia service users and nine with caregivers. Interviews were conducted by two trained field researchers; both clinical psychologists fluent in the first language of participants. All interviews were recorded, translated and transcribed. Data were thematically analysed using NVivo 9.

RESULTS

Participants linked the illness to witchcraft, poverty and stress. Family conflict was recognised in the course of the illness, causing stress and challenges for emotional well-being. Knowledge of diagnosis and biomedical treatment was minimal. Key factors recognised by service users as promoting recovery were the ability to work, and the support of traditional healers and religious structures.

CONCLUSION

Based on the findings of this study, a group psychosocial rehabilitation intervention emerged as a recommendation, with the incorporation of psycho-education, adherence support, coping skills, and opportunities for income generation and productive activity. The importance of also enlisting the support of religious leaders and traditional healers in supporting recovery is emphasised.

Effectiveness of quality improvement strategies for coordination of care to reduce use of health care services: a systematic review and meta-analysis

BACKGROUND

Frequent users of health care services are a relatively small group of patients who account for a disproportionately large amount of health care utilization. We conducted a meta-analysis of the effectiveness of interventions to improve the coordination of care to reduce health care utilization in this patient group.

METHODS

We searched MEDLINE, Embase and the Cochrane Library from inception until May 2014 for randomized clinical trials (RCTs) assessing quality improvement strategies for the coordination of care of frequent users of the health care system. Articles were screened, and data abstracted and appraised for quality by 2 reviewers, independently. Random effects meta-analyses were conducted.

RESULTS

We identified 36 RCTs and 14 companion reports (total 7494 patients). Significantly fewer patients in the intervention group than in the control group were admitted to hospital (relative risk [RR] 0.81, 95% confidence interval [CI] 0.72-0.91). In subgroup analyses, a similar effect was observed among patients with chronic medical conditions other than mental illness, but not among patients with mental illness. In addition, significantly fewer patients 65 years and older in the intervention group than in the control group visited emergency departments (RR 0.69, 95% CI 0.54-0.89).

INTERPRETATION

We found that quality improvement strategies for coordination of care reduced hospital admissions among patients with chronic conditions other than mental illness and reduced emergency department visits among older patients. Our results may help clinicians and policy-makers reduce utilization through the use of strategies that target the system (team changes, case management) and the patient (promotion of self-management).
