Remission amongst elderly schizophrenia patients

Functioning in schizophrenia: Recommendations of an expert panel

Functioning is a fundamental dimension across all aspects of life, frequently compromised or reduced in individuals with schizophrenia. However, the lack of a commonly agreed definition of functioning in schizophrenia makes it difficult to apply this concept in clinical practice. In this document, we make a detailed analysis of the literature to identify and define functioning and describe how it can be used in clinical practice today. We performed a preliminary literature search in the MEDLINE database (via PubMed) for articles discussing functioning in schizophrenia. The articles retrieved were then read and discussed by a panel of psychiatrists specialising in schizophrenia. The conclusions reached in this meeting formed the basis for a new exhaustive literature search for the purpose of synthesising the evidence published in the past 5 years. In this article, we show the importance a comprehensive, modern, homogeneous definition of functioning in schizophrenia, propose a definition of functioning, and put forward a series of recommendations for assessing functioning in clinical practice. We also review current unmet needs and highlight the need for a standardised tool for evaluating functioning.

Predictive factors of functional remission in patients with early to mid-stage schizophrenia treated by long acting antipsychotics and the specific role of clinical remission

BACKGROUND

Functional remission has become a major therapeutic objective in schizophrenia, but the probability of such positive outcome has a large variability, ranging from 15% to 51%. Additionally, how clinical remission constitutes a prerequisite for functional remission also remains unclear.

METHODS

A prospective observational study was conducted in French schizophrenic patients who initiated treatment with a long-acting injectable (LAI) after an acute episode. Functional and clinical remissions were assessed using the FROGS and the Andreasen criteria, and the role of clinical remission and predictive factors of functional remission was evaluated.

RESULTS

Three hundred three patients with schizophrenia (DSM-IV criteria) were followed for 12 months. At 12 months, 45.1% of the patients reached functional remission while 55.1% obtained clinical remission. Clinical remission facilitated functional remission (OR = 14.74), especially in patients with psychosis for less than 5 years (OR = 23.73). Other predictive factors concerned the family environment, education level, employment status, baseline functioning levels and level of insight.

CONCLUSIONS

About half of patients treated with LAI reached functional remission after one year of follow-up. Reduced clinical symptoms and reaching clinical remission largely favored functional remission. These results stress the importance of continuous and appropriate symptomatic treatment to reach functional remission and maximize recovery chances.

Functional remission in schizophrenia: A FROGS-based definition and its convergent validity

Functional remission concerns only one third of schizophrenia patients who achieved symptomatic remission. We previously developed a scale devoted to functional remission, named the FROGS (Functional Remission Of General Schizophrenia). This instrument encompasses three clinically relevant dimensions. The aim of this study is to provide a threshold for functional remission relying on these three dimensions, and to compare its psychometric properties with other scales devoted to functional remission. We tested the characteristics of functional remission according to the FROGS. The FROGS was used in different European countries and compared to other valid scales (GAF, PSP and PSRS) in a sample of 295 schizophrenia patients. The association with different parameters as external validators was assessed, including clinical remission. A comparison of the classifying properties of each scale compared to the others was made. The four instruments were equally influenced by the PANSS score, the clinical remission according Andreassen's criteria, the number of past hospitalizations and the presence of a paid working activity. These findings provide a simple threshold for the FROGS, tightly linked to the definition of functional remission, with a good convergent validity. This instrument might be easily used to facilitate the assessment of functional remission in schizophrenia.
