Determinants of duration of untreated psychosis in an Irish catchment area sample

The effects of childhood adversity on treatment delays and its components in first-episode psychosis

Apart from increasing risk for psychotic disorders, childhood adversity has been associated with worse outcomes. One way in which childhood adversity may worsen outcomes is by lengthening treatment delays, which are associated with negative impacts. We tested the influence of childhood trauma on treatment delays, measured as the duration of untreated psychosis (DUP), and its help-seeking and referral components, in a first-episode psychosis cohort (N = 203). We accounted for pertinent social (e.g., migrant status) and other determinants (i.e., age at onset, diagnosis, symptoms) of treatment delays. Multiple linear regression analyses revealed that for a one-unit increase in Childhood Trauma Questionnaire (CTQ) scores, average overall DUP increased by 25%. Higher CTQ scores also significantly predicted help-seeking and referral DUPs. Patients with schizophrenia-spectrum psychosis had longer help-seeking and total DUPs than those with affective psychosis. More severe positive symptoms predicted longer help-seeking DUPs, while more severe negative symptoms predicted longer referral DUPs. Indicators of social disadvantage did not affect DUP. Our results show that childhood trauma increases DUP by prolonging the help-seeking process and delaying access to mental healthcare even after help is sought. Early identification of psychosis among populations with trauma histories seems warranted and can likely positively impact outcomes.

Is early management of psychosis designed for migrants? Improving transcultural variable collection when measuring duration of untreated psychosis

AIM

A background of migration is an established risk factor for psychosis. At the same time, over the last 25 years, many countries have developed specialized services for the assessment and care of people with early psychosis. Evaluation of these services often focuses on the duration of untreated psychosis (DUP).

METHODS

We conducted a systematic review with an electronic search of key words in 3 databases to determine the extent to which studies measuring DUP consider transcultural variables, including migration status, national origin, ethnicity and language.

RESULTS

We identified 18 studies that included transcultural variables and measured DUP. They differed in their design, aims and methodology, and could not be directly compared. Common themes nonetheless appeared.

CONCLUSIONS

Most of the studies exploring DUP took little account of transcultural variables. Definitions of transcultural indicators were heterogeneous and often vague. Lack of language proficiency was often an exclusion criterion, and none of the studies used interpreters. We propose some basic transcultural variable and recommendations to include in future studies and recommendations to improve their internal and external validity.

Determinants of duration of untreated psychosis among first-episode psychosis patients in Denmark: A nationwide register-based study

BACKGROUND

Information on determinants of duration of untreated psychosis (DUP) is still needed to inform campaigns targeting people with first episode psychosis (FEP). This nation-wide study analysed the association between demographic factors (age, sex, ethnicity, marital status, and geographic area), premorbid and illness-related factors (global functional level, substance misuse, and contact to police), healthcare factors (referral source and first FEP contact) and DUP.

METHOD

The study population of 1266 patients aged 15-25years diagnosed with FEP (ICD10 F20.0-F20.99) was drawn from the Danish National Indicator Project during 2009-2011. The study population was combined with data from national administrative registers. A multinomial regression model was estimated to analyse the impact of demographic, premorbid and illness-related, and healthcare factors on DUP.

RESULTS

One third of the population had a DUP below 6months. DUP longer than 12months was associated with older age at onset, being female, having cannabis misuse, and living in peripheral municipalities. Being charged by the criminal authorities during one year before FEP was associated with a DUP over 6months.

CONCLUSION

DUP is related to a number of demographic, premorbid and healthcare factors. These findings suggest that future information campaigns should focus on increasing the awareness of early signs of psychosis not only among mental health professionals but also other professionals in contact with adolescents such as the police. It may also be useful to consider how to target information campaigns towards persons living in peripheral areas.

The economic cost of schizophrenia in Ireland: a cost of illness study

Objectives: Although there are many published reports about the human cost of schizophrenia, there are far fewer estimates of its economic cost, particularly in Ireland. The aim of this study was to provide a prevalence-based estimate of the costs associated with schizophrenia in Ireland during 2006.

Method: Using standard Cost of Illness (COI) procedures we compiled data from many sources including the Health Research Board, the Department of Health and Children and other government publications. Costs relating to health and social care, informal care, lost productivity, premature mortality and other public expenditures were included. Where national data were unavailable, we used bottom-up data from a geographically defined catchment area study and, in some instances, costs from two catchment areas were averaged. We did not measure human or intangible costs.

Results: The estimated total cost of schizophrenia was €460.6 million in 2006. The direct cost of care was €117.5 million and the burden of indirect costs was €343 million. The cost of lost productivity due to unemployment, absence from work and premature mortality was €277 million. Within indirect costs, the expenditure on informal care borne by families was €43.8 million.

Conclusions: Schizophrenia is not a very common condition but is an expensive one. This is attributable to its young age at onset, relatively low mortality rate and high severity particularly in terms of its impact on future employment. Measures to improve outcomes coupled with measures to improve employment such as supported employment strategies may impact significantly on the cost of schizophrenia. The study is limited because the national unit costs of many variables are not directly available and these Irish data are likely to be an underestimate. However, the results are comparable with a 2005 cost of illness study UK study.

First episode psychosis and the trail to secondary care: help-seeking and health-system delays

BACKGROUND

People experience delays in receiving effective treatment for many illnesses including psychosis. These delays have adverse consequences in heart disease and cancer, and their causes have been the subject of much research but only in recent years have pathways to care in psychosis received such attention. We sought to establish if, when and where people seek help in the early phase of psychosis in a representative sample.

METHODS

One hundred and sixty-five people with first episode psychosis, referred from community-based psychiatric services and a private psychiatric facility to an early intervention service over 18 months, were interviewed with the Structured Clinical Interview for DSM-IV diagnoses. Symptoms were measured using the Schedule for the Assessment of Positive Symptoms, Schedule for the Assessment of Negative Symptoms and the Calgary Scale. Duration of untreated illness (DUI) and duration of untreated psychosis (DUP) were established using the Beiser Scale. Pathways to mental health services were systematically detailed through interviews with patients and their families.

RESULTS

The final sample consisted of 142 (88M, 54F) cases after those with psychosis due to a general medical condition and those without pathway and DUP data were excluded. Less than half of participants initiated help seeking themselves. Of those who did seek help (n = 57) 25% did so during the DUI. Those who had a positive family history of mental illness and poorer premorbid adjustment were significantly less likely to seek help for themselves and those who did not seek help were more likely to require hospitalisation. Families were involved in help seeking for 50% of cases and in 1/3 of cases did so without the affected individual participating in the contact. Being younger and having more negative symptoms were associated with having one's family involved in help seeking. Delays to effective treatment from the onset of psychosis were evenly split between "help-seeking delays" and "health-system delays". Having a family member involved in help seeking and better premorbid adjustment were independently associated with shorter help-seeking delays when measured from the onset of psychosis. Being female, having better premorbid adjustment and fewer negative symptoms were associated with shorter help-seeking delays from the onset of illness. Those with a non-affective psychosis had significantly longer system delays.

CONCLUSION

Many people with first episode psychosis do not initiate help-seeking for themselves particularly those with a relative affected by mental illness. Those with poor premorbid adjustment are at particular risk of longer delays. Poor premorbid adjustment compounded by long delays to effective treatment reduces the likelihood of a good outcome. Families play a vital role in hastening receipt of effective treatment.
