Assessing the severity of functional impairment of psychiatric disorders: equipercentile linking the mini-ICF-APP and CGI

Impact of psychopathology on day-to-day living in patients with schizophrenia: A network analysis

Although the relationship between schizophrenia and disability is well established, the association between the symptoms of the disorder and functional domains remains unclear. The current study explored the nuances of the relationship between symptoms and domains of functioning in a sample of 1127 patients with schizophrenia. We assessed the symptoms of schizophrenia with the Positive and Negative Syndrome Scale (PANSS) and psychosocial functioning with the mini-ICF-APP (mini-International Classification of Functioning Rating for Limitations of Activities and Participation in Psychological Disorders). The mean PANSS score was 94.28 (27.20), and the mean mini-ICF-APP score was 25.25 (8.96), both of which are indicative of severe symptom load and impairment. We were able to show a strong relationship and overlap between symptoms and disability in patients with schizophrenia. We identified several symptoms related to functional impairment. Deficits in judgment and abstract thinking contribute to impairment through poor adherence (to routines and compliance with rules) and difficulties in planning and organizing. We believe that in schizophrenia, symptoms and their interactions constitute a disorder beyond any single manifestation. Furthermore, we suggest that cognitive testing and cognitive treatment should become part of the standard of care for patients with schizophrenia.

An Innovative Approach to the Dismantlement of a Forensic Psychiatric Hospital in Italy: A Ten-year Impact Evaluation

Aims

This study aimed to evaluate the impacts of a pilot project concerning the closure of a Forensic Psychiatric Hospital (FPH) inspired by Human Development Theory and the Capability Approach.

Background

The dismantlement of the FPH of Barcellona Pozzo di Gotto (Sicily Region in Italy) began in 2010 with the pilot project Luce é Libertà and ended in 2017. With the closure of six FPHs, Italy officially became the first country worldwide to close such institutions. After the closure of FPHs, some critical issues emerged, and the debate shifted to developing small-scale facilities and residences for the execution of security measures (RESM). However, few studies have provided results on the cohort of patients discharged from FPHs.

Objective

Following are the objectives of this study: a) Assessing the effectiveness of the pilot project in terms of better functioning accordingly to the Classification of Functioning of Disability and Health (ICF) framework, social and labour insertion, health conditions, level of dangerousness to other, rate of readmission in forensic services, b) cost analysis, and c) describing how the CA has been applied and translated into methodological and administrative devices and concrete intervention strategies.

Methods

A pre-post evaluation design was performed with a comparison between the intervention and the control group for the healthcare cost analysis. Data were collected from 2010 to 2019 at three points: T0) as a baseline, T1 and T2) for the follow-up. The instruments are a structured questionnaire, the Scale HoNOS Secure, 4 sub-scales of ICF (Activity and participation dimensions: sociality, culture, and knowledge, daily life, income, and work) (Cronbach's Alpha from 0.76 to 0.94), and n.20 interviews with key stakeholders and beneficiaries.

Results

Main results include a) the discharge of 55 patients through the use of a person-centered approach and the Personal Capability Budget (PCB), b) the expansion of substantial freedom of choice and the improvement of ICF score (t-test Sig. <, 02), c) the reduction of the risk for others and themselves (Mean Diff. -2,15 Sig. .000), d) at T2 42% of beneficiaries achieved a job placement and 36% were living in one's own home, e) at T2 the need of security measures has reduced from the initial 70% to 6.8%, and f) reduction of the healthcare costs from the fourth year onwards.

Conclusion

Indications emerge to support processes of deinstitutionalisation and capabilities expansion through innovative models, a person-centered approach supported by PCBs, social finance, and social impact investments.

Utility and validity of the Brief Psychiatric Rating Scale (BPRS) as a transdiagnostic scale

The Brief Psychiatric Rating Scale (BPRS) was originally conceived to assess psychopathology in several psychiatric disorders, making it an appropriate candidate to be used as a transdiagnostic instrument. We analyzed the utility and validity of the BPRS in a diagnostically heterogeneous sample of 600 psychiatric inpatients. As a comparator, we chose the mini-ICF-APP, a scale used to measure functioning and impairment across the diagnostic spectrum. Both scales had good internal consistency. The BPRS and the mini-ICF-APP showed a moderate correlation, with good levels of agreement. We were able to identify general symptoms present across the diagnostic spectrum, influencing severity and a cluster of symptoms specific for each diagnosis. Our results show the utility and validity of the BPRS as a transdiagnostic assessment tool that could easily be introduced in routine clinical work.

One-year follow-up of functional impairment in inpatients with mood and anxiety disorders - Potentials of the Mini-ICF-APP

BACKGROUND

The aim of the study was to investigate functional impairment and its relationship to illness severity in a sample of patients with a diagnosis of mood or anxiety disorder during inpatient treatment and 1 year after discharge.

METHODS

Two hundred thirty-nine inpatients with primary diagnoses of mood or anxiety disorders were assessed at baseline and at follow-up by a range of validated instruments. Mini-ICF-APP was used for the assessment of functional impairment, BDI-II for the assessment of clinical symptoms and remission. Sample characteristics and measures of impairment at baseline and at follow-up were analysed descriptively. Symptomatically remitted and non-remitted patients were compared with regard to capacity limitations.

RESULTS

Initially, the sample showed considerable impairment in many capacities, particularly endurance, spontaneous activities, structuring of tasks, competency and flexibility. After 1 year, all capacities significantly improved. The level of impairment was correlated with employment status and severity of clinical symptoms. About 50% of the patients remitted in clinical symptomatology. Retrospectively, the remitted and the unremitted did not differ in functional impairment at baseline but there were considerable differences at follow-up.

CONCLUSIONS

Mini-ICF-APP is a useful instrument to monitor functional status and change in psychiatric samples, complementing the usual focus on symptom reduction.

Exploring the factor structure of the mini-ICF-APP in an inpatient clinical sample, according to the psychiatric diagnosis

INTRODUCTION

Psychosocial functioning is a key factor determining prognosis, severity, impairment and quality of life in people who have a mental disorder. The mini-ICF-APP was developed to provide a standardised classification of functioning and disability. However, despite its gaining popularity little is known about its structure and performance. This paper examines the structure of the mini-ICF-APP using factor analysis techniques.

MATERIALS AND METHODS

In a clinical sample of 3178 patients, with psychiatric diagnoses from several ICD-10 categories, we analysed internal consistency, item inter-correlations and the factorial structure of the data, with reference to ICD-10 diagnostic categories; Neurocognitive Disorders; Alcohol Use Disorders; Substance Use Disorders; Schizophrenia and Psychotic Disorders; Bipolar Disorder; Major Depressive Disorder; Anxiety Disorders; Personality Disorders; and Neurodevelopmental Disorders.

RESULTS

We found good internal consistency and item inter-correlations (Cronbach alpha=0.92) for the mini-ICF-APP. We were able to identify pivotal domains (flexibility, assertiveness and intimate relationships), which demonstrate sub-threshold influences on other domains. The factor analysis yielded a one-factor model as ideal for the whole sample and for all diagnostic categories. For some diagnostic categories the data suggested a two or three-factor model, however, with poorer fit indices.

CONCLUSIONS

The factor structure of the mini-ICF-APP appears to modify according to the main diagnosis. However, a one-factor model demonstrates better fit regardless of diagnostic category. Consequently, we consider the mini-ICF-APP to be a trans-diagnostic measurement instrument for the assessment and grading of psychosocial functioning. The use of the mini-ICF-APP sum score seems to best reflect the degree of impairment in an individual, even taking into account that affected domains may lead to sub-threshold effects on other domains.

Are patients improving during and after a psychiatric hospitalisation? Continuity of care outcomes of compulsory and voluntary admissions to an Italian psychiatric ward

Background: To compare the characteristics of compulsory admissions (CAs) and voluntary admissions (VAs) in a General Hospital Psychiatric Unit (GHPU), and to assess whether CA and VA patients’ outcomes improved during hospitalisation and followup in mental health services (MHS) based on community continuity of care.

Design and methods: Observational longitudinal study comparing 19 CAs and 83 VAs consecutively admitted to GHPU of Udine, Italy, and followed-up for six-months by MHS. Five psychometric scales assessed psychosocial and clinical characteristics for each patient at admission (T0), discharge (T1) and follow-up (T2). Statistical analyses were performed using: multivariate logistic regression for comparing CA and VA; Friedman χ2 and Mann-Whitney tests for outcomes’ improvement.

Results: Being hospitalised for a psychotic crisis was the most significant predictor of CA (OR = 5.07). An outcomes’ improvement was observed from T0 to T1 in almost all psychometric tests, while from T1 to T2 only for PSP-A (useful social activities), CGI-S (severity of illness) and CGI-EI (drug’s efficacy related to side effects). CA was associated to lower performances in all scales at T0, in GAF and CGI-S at T1, while no difference with VA was observed at T2.

Conclusions: CA and VA patients improved to a same extent during hospitalisation and follow-up, particularly in relation to social functioning. This fosters the hypothesis that communitybased MHS using a longitudinal continuity of care model might achieve recovery in a long-term perspective. Future research may benefit by considering patients’ subjective experiences and assessing long-term improvement in those who received personcentred interventions.

Clinical Outcome Measure Crosswalks in Alzheimer's Disease: A Systematic Review

BACKGROUND

A key challenge in studies that model outcomes, disease progression, and cost-effectiveness of existing and emerging dementia treatments is the lack of conversion criteria to translate, or 'crosswalk', scores on multiple measurement scales. Clinical status in dementia is commonly characterized in the cognitive, functional, and behavioral domains.

OBJECTIVE

We conducted a systematic review of peer-reviewed dementia measure crosswalks in the three domains.

METHODS

We systematically reviewed published literature for crosswalks between scales used to measure cognitive, functional, or behavioral outcomes in Alzheimer's and related dementias. The search was conducted in PubMed, and additional crosswalks were identified through snowballing and expert input from dementia modelers.

RESULTS

Of the reviewed articles, 2,334 were identified through a PubMed search, 842 articles were sourced from backward and forward citation snowballing, and 8 additional articles were recommended through expert input. 31 papers were eligible for inclusion, listing 74 unique crosswalks. Of those, 62 (83.8%) were between endpoints of the cognitive domain and 12 (16.2%) were either between endpoints of the functional domain or were hybrid in nature. Among crosswalks exclusively in the cognitive domain, a majority involved the Mini-Mental State Examination (MMSE) (37 crosswalks) or the Montreal Cognitive Assessment (MoCA) and its variants (25 crosswalks). MMSE was directly compared to MoCA or MoCA variants in 16 crosswalks.

CONCLUSION

Existing crosswalks between measures of dementia focus largely on a limited selection of outcome measures, particularly MMSE and MoCA. Few crosswalks exist in the functional domain, and no crosswalks were identified for solely behavioral measures.

Assessing the severity of psychiatric disorders using the Health of the Nation Outcome Scales: An equipercentile linking analysis

OBJECTIVE

The Health of the Nation Outcome Scales was developed as an overall measure of mental health, applicable to the complete range of psychiatric disorders. Meanwhile, it is a benchmark tool for service providers and is also used for the allocation of costs and funding. The ability of the Health of the Nation Outcome Scales to assess and differentiate the severity of psychiatric disorders is largely unknown, as it is the interpretation of a change in score. We aim to establish Health of the Nation Outcome Scales cut-off and benchmark values for severity and improvement - respectively change, using equipercentile linking to the Clinical Global Impression scales.

METHODS

In a clinical sample of 30,616 individuals with a psychiatric disorder, we used a multivariate regression analysis to determine the correlation between the scales and possible confounders. We used an equipercentile linking analysis of the Clinical Global Impressions severity scale with the Health of the Nation Outcome Scales sum score to establish cut-off values for severity. The linking of the Health of the Nation Outcome Scales sum score difference and the percentage of change to the Clinical Global Impression improvement scale determined benchmark values for change (i.e. improvement or deterioration).

RESULTS

The Health of the Nation Outcome Scales and Clinical Global Impression scales showed a Spearman correlation of 0.38 (p < 0.000). Clinical Global Impression-Severity: 'borderline-ill' corresponded to Health of the Nation Outcome Scales score 3-5; 'mildly ill' to 6-10; 'moderately ill' to 11-16; 'markedly ill' to 17-25; 'severely ill' to 26-35; and 'extremely ill' to a score ⩾36. The Spearman correlation between the percentage change of the Health of the Nation Outcome Scales was 0.39 (p > 0.000); Clinical Global Impression-Improvement: 'minimally improved' corresponded to Health of the Nation Outcome Scales reduction of 4 points or 9%; 'much-improved' to 12 points or 48%; 'very-much-improved' to ⩾20 points or ⩾90%. Clinical Global Impression-Improvement: 'minimally worse' corresponded to an increase of 6 points or 25%; 'much-worse' to 12 points or 54%; and finally, 'very-much-worse' to >18 points or ⩾82%.

CONCLUSION

Our results allow for the comparison of severity and response to treatment of patients with a psychiatric disorder, independent of diagnosis.

Feasibility and Efficacy of a Psychological Therapy for Patients With a Schizophrenic Psychosis in an Inpatient Setting: Study Protocol of a Randomized Switch Controlled Trial

Background: Schizophrenic psychoses are severe mental disorders. Despite advances in treatment, outcomes are still unsatisfactory. Pharmacological treatments are still limited, in particular regarding improvements in psychosocial functioning and neuro-cognitive impairment. In recent years new psychological therapies have been developed, demonstrating promising results. However, most of these interventions have been designed for and studied in outpatients; their efficacy and feasibility for patients requiring hospitalization is still unknown. Therefore, we have designed a clinical trial to compare a neuro-cognitive (Integrated Neuro-cognitive Treatment INT); a cognitive-behavioral (Integrated Psychological Therapy IPT); and a control (Cogpack CGP) intervention for patients with a schizophrenic psychosis hospitalized for treatment.

Methods: In a three-parallel-arm, single-blind, randomized, controlled study, we compare INT, IPT, and CGP. Participants will take part in two weekly sessions of one intervention for at least 16 sessions. If due to randomization, participants are allocated to a treatment arm not suitable for them, they are allowed to switch intervention after four sessions. Based on a sample size calculation, recruitment will continue until 30 participants have completed the intervention for each treatment arm.

Outcome Measurement: Primary outcomes are: change in symptom as measured by the Positive and Negative Syndrome Scale (PANSS), change in psychosocial functioning as assessed by the mini ICF-APP and neuro-cognitive performance, assessed by the Matrics Cognitive Consensus Battery (MCCB). Other outcomes of interest are the Brief Symptom Inventory (BSI) and the Health of the Nation Outcome Scales (HoNOS); together with prescribed medication, treatment retention and completion rates. Outcomes will be measured at baseline, 2 weeks into treatment (prior to a potential switch of intervention arm), post-treatment and at 6 and 12-month post-treatment follow-ups.

Expected Outcomes: We expect an overall improvement; however, with differences in specific domains for each treatment arm, with those completing INT showing better outcomes than IPT and CGP, respectively. We anticipate that lower functioning participants will drift to CGP and higher functioning participants to INT.

Conclusion: Due to the complexity of treatment for patients with a schizophrenic psychosis, we consider it crucial to compare different treatment options for those more severely affected, therefore, requiring inpatient treatment.
