Five-year outcome of clinical recovery and subjective well-being in older Dutch patients with schizophrenia

Outcome of schizophrenia in later life can be evaluated from different perspectives. The recovery concept has moved forward this evaluation, discerning clinical-based and patient-based definitions. Longitudinal data on measures of recovery in older individuals with schizophrenia are scant. This study evaluated the five-year outcome of clinical recovery and subjective well-being in a sample of 73 older Dutch schizophrenia patients (mean age 65.9 years; SD 5.4), employing a catchment-area based design that included both community living and institutionalized patients regardless of the age of onset of their disorder. At baseline (T1), 5.5% of participants qualified for clinical recovery, while at five-year follow-up (T2), this rate was 12.3% (p = 0.18; exact McNemar's test). Subjective well-being was reported by 20.5% of participants at T1 and by 27.4% at T2 (p = 0.27; exact McNemar's test). Concurrence of clinical recovery and subjective well-being was exceptional, being present in only one participant (1.4%) at T1 and in two participants (2.7%) at T2. Clinical recovery and subjective well-being were not correlated neither at T1 (p = 0.82; phi = 0.027) nor at T2 (p = 0.71; phi =-0.044). There was no significant correlation over time between clinical recovery at T1 and subjective well-being at T2 (p = 0.30; phi = 0.122) nor between subjective well-being at T1 and clinical recovery at T2 (p = 0.45; phi =-0.088). These results indicate that while reaching clinical recovery is relatively rare in older individuals with schizophrenia, it is not a prerequisite to experience subjective well-being

Comparison of social functioning in community-living older individuals with schizophrenia and bipolar disorder: a catchment area-based study

Objective: Preserved social functioning is of utmost importance for older individuals living in the community to maintain independency. However, in patients with schizophrenia or bipolar disorder, it remains unclear which factors influence social functioning in later life. Methods: In a catchment area-based study in Amsterdam, The Netherlands, 120 older (>60 years) community-living patients with schizophrenia (n = 73) and with bipolar disorder (n = 47) were included. Clinical interviews on social functioning and psychometric measurements were applied. Results: Patients with schizophrenia scored lower on all social measures (social functioning, social participation, network size, availability of confidants) compared with their peers with bipolar disorder. In patients with schizophrenia, lower social functioning was associated with having more negative symptoms and depressive symptoms. Age of onset was also associated with social functioning in schizophrenia, with higher scores in very late-onset schizophrenia-like psychosis. Unfavourable social functioning in patients with bipolar disorder was associated with lower cognitive functioning. Furthermore, in both groups, social functioning was not related to age, having offspring or the presence of a partner. Conclusions: In community-living older patients, schizophrenia has a more disruptive effect on social functioning than bipolar disorder, except in those with a very late-onset schizophrenia-like psychosis. Minimizing residual depressive symptoms and optimizing cognitive functioning may be targets for improving social functioning and independent-living in older patients with severe mental illness

Promoting Personal and Social Recovery in Older Persons with Schizophrenia: The Case of The New Club, a Novel Dutch Facility Offering Social Contact and Activities

Many older community-living persons with schizophrenia report unmet psychological and social needs. The Amsterdam-based New Club is a novel facility that intends to foster self-reliance and social participation in this group. To explore participants’ and staff perceptions, a naturalistic qualitative study combined participant observation with interviews. The results illustrate how the New Club contributes to the personal and social recovery of its participants. At the personal level, attending the facility, activation and feeling accepted were valued positively. At the social level, engaging with others, experiencing a sense of community, and learning from one another’s social skills were positive contributors. Next, various environmental factors proved important. The New Club demonstrates the feasibility of creating a facility that offers an accepting and non-demanding social environment to older community-living individuals with severe mental illnesses. It may offer a suitable alternative for the more demanding psychotherapeutic interventions offered to younger populations

Admixture analysis of age at onset in older patients with schizophrenia spectrum disorders

The nature of schizophrenia spectrum disorders with an onset in middle or late adulthood remains controversial. The aim of our study was to determine in patients aged 60 and older if clinically relevant subtypes based on age at onset can be distinguished, using admixture analysis, a data-driven technique. We conducted a cross-sectional study in 94 patients aged 60 and older with a diagnosis of schizophrenia or schizoaffective disorder. Admixture analysis was used to determine if the distribution of age at onset in this cohort was consistent with one or more populations of origin and to determine cut-offs for age at onset groups, if more than one population could be identified. Results showed that admixture analysis based on age at onset demonstrated only one normally distributed population. Our results suggest that in older schizophrenia patients, early- and late-onset ages form a continuum

Course and predictors of symptomatic remission in late-life schizophrenia: A 5-year follow-up study in a Dutch psychiatric catchment area

Background: The number of older schizophrenia patients is growing, the majority being treated in outpatient settings. Reported symptomatic remission rates in younger cohorts vary largely. Further insight into course trajectories and putative predictors of remission in older persons with schizophrenia is needed. Methods: 5-year follow-up course trajectories of symptomatic remission were examined in a catchment area-based group of 77 older Dutch patients (mean age 66.0 years)with schizophrenia or schizoaffective disorder. A modified version of the ‘Remission in Schizophrenia Working Group’ criteria was used to determine remission status. In individuals who did not fulfil remission criteria at baseline (n = 56), predictors of conversion to remission status at 5-year follow-up were analysed using multivariable regression analyses. Results: A substantial increase in remission rate at 5-year follow-up (27.3% at baseline (T1), 49.4% at follow-up (T2))was found. Of all participants, 23.4% was in remission at both assessments and 46.8% was in non-remission at both assessments. 26.0% of the participants converted from non-remission at T1 to remission at T2, while 3.9% fell back from remission at T1 to non-remission at T2. Two significant baseline predictors of conversion to remission at follow-up were found: lower score on the PANSS positive symptom subscale, and having a partner. Conclusion: Symptomatic remission was as an attainable goal for almost half of all older patients with schizophrenia or schizoaffective disorder at 5-year follow-up. With a lower PANSS positive symptom subscale score, and having a partner emerging as the only predictors of conversion to remission, there remains a need to search for modifiable predictors

Social Functioning Among Older Community-Dwelling Patients With Schizophrenia: A Review

Social dysfunction is a hallmark of schizophrenia and a major constituent of its burden of disease. There is a need for more data on social functioning of older schizophrenic patients, because their numbers are rapidly growing and most are residing within the community. This article reviews existing evidence on social functioning in community-dwelling schizophrenic patients older than 55 years, focusing on social roles, social support, and social skills. Thirty-six publications proved fit for inclusion in the review. Studies from outside the United States were underrepresented. The available data suggest that the majority of older schizophrenic patients are well behind their healthy age-peers with respect to various aspects of social functioning. At the same time, a considerable heterogeneity among patients can be found. Cognitive abilities feature as a factor of major impact on social functioning, outweighing clinical symptoms. When evaluating social functioning both objective and subjective appraisals should be taken into account, because they may highlight different aspects of social functioning. Social support, impact of gender, and specific characteristics of older-old patients figure among areas that should be given priority in future research of social functioning in late life schizophrenia.

Mortality and Its Determinants in Late-Life Schizophrenia: A 5-Year Prospective Study in a Dutch Catchment Area

It is uncertain if the raised mortality in schizophrenia persists in later life. Register-based studies suggest that excess mortality continues, although at a lower level than in younger age groups. However, prospective follow-up studies of older schizophrenia samples are lacking. A cohort of 157 older patients (mean age at study entry: 68 years) diagnosed with schizophrenia or schizoaffective disorder in a psychiatric catchment area in Amsterdam, the Netherlands was studied. Standardized mortality rate (SMR) was estimated at a 5-year follow-up, in referral to the same age group in the general catchment area population. The impact on survival time of a range of independent demographic and clinical predictors was evaluated. The cohort had an all-cause SMR of 1.89 (95% CI: 1.28-2.70). SMR was higher in men (2.60; 95% CI: 1.42-4.37) than in women (1.78; 95% CI: 1.02-2.90). All deaths were from natural causes. Reduced survival was associated with higher age (HR: 1.10; 95% CI: 1.05-1.16), male gender (HR: 3.94; 95% CI: 1.87-8.31), and having had one or more compulsory admissions in the past (HR: 2.61; 95% CI: 1.46-4.68). In contrast, no mortality associations were found with diagnosis (schizophrenia versus schizoaffective disorder), age at onset of the disorder, or current prescription of antipsychotics. The excess mortality in schizophrenia continues into late life, affecting men more often than women. Given the poor insight into the underlying mechanisms of this disquieting finding, there is a need to identify modifiable clinical and social risk factor
