Suicide attempts in people with schizophrenia before and after participating in an intensive case managed community program: A 20-year follow-up

The relationship of the methylation status and polymorphism of glucocorticoid receptor gene (NR3C1) with attempted suicide or non-suicidal self-injury patients in schizophrenia

We aim to investigate the methylation of NR3C1 gene promotor and NR3C1 BclI polymorphism in schizophrenia (SCZ) patients with attempted suicide or non-suicidal self-injury (NSSI). A sample of 112 patients with SCZ was included in the study. Structured Clinical Interview for Diagnostic and Statistical Manual-Fourth Edition Axis I Disorders was used to confirm the diagnosis according to The Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision criteria. The patients were evaluated by data forms that had sociodemographic, suicidal behavior, and NSSI information. Methylation-specific polymerase chain reaction (PCR) was used to identify the methylation of the NR3C1 gene. The analysis of the BclI polymorphism of the NR3C1 gene was evaluated by using the PCR restriction fragment length polymorphism. Our results revealed that although the NR3C1 gene methylation was not statistically significantly different, there was a significant difference in NR3C1 genotype distribution among the SCZ groups with and without attempted suicide. SCZ patients carrying the CC genotype had a lower risk of attempted suicide (Odds Ratio [OR]: 0.421; 95% Confidence Interval [CI]: 0.183-0.970; p = 0.040), while having the GG genotype in SCZ patients was associated with a higher risk of attempted suicide (OR: 3.785; 95% Cl: 1.107-12.945; p = 0.042). Additionally, due to NSSI in SCZ patients, there were no significant differences in NR3C1 gene methylation and NR3C1 genotype distribution among the groups. We propose that the NR3C1 BclI polymorphism may be associated with attempted suicide in Turkish patients diagnosed with SCZ.

Family psychoeducation in schizophrenia and schizophrenia related disorder, treatment compliance, and suicidal risk reduction: questions about their relationship from a naturalistic observation

Introduction

The Profamille V3.2 multi-family psycho-educational program directed at caregivers of relatives with schizophrenia or schizophrenia related disorder has been shown to decrease the annual prevalence of suicide attempts. It has been reported that psychoeducation of families can sometimes improve compliance with treatment. This study investigates whether the Profamille program improves compliance and thus reduces the risk of suicide among patients.

Method

This is a retrospective study of 179 groups of family caregivers, encompassing 1946 participants enrolled in Module 1 of the Profamille program and followed up one year after completion of the module. Evaluations were conducted using questionnaires filled out by family caregivers at three distinct times: prior to beginning the program, upon its completion, and again one year following its conclusion. The annual prevalence of suicide attempts was measured both before the program began and one year after its conclusion, while compliance to treatment was evaluated at the start and end of the program.

Result

After the Profamille program, the annual prevalence of suicide attempts fell by a factor of 2 (p-value = 0.00002) and patient compliance improved (p-value <0.000001). This reduction in suicide attempts was observed independently of improved compliance. Compliance seems to have an additional effect, but only after participation in the program.

Conclusion

The Profamille program reduces patients' risk of suicide even when patients are not taking the treatment. When family psychoeducation is not proposed in schizophrenia or schizophrenia related disorder, this can represent a loss of chance for patients.

Incidence and Risk Profiles for Suicide Mortality in Patients With Schizophrenia Receiving Homecare Case Management in Taiwan

Case management (CM)-based community therapy for patients with schizophrenia had little effect on reducing suicide mortality. We investigate the long-term suicide mortality outcome and associated risk factors in patients with schizophrenia receiving homecare (CM) in Taiwan. We enrolled a nationwide cohort of patients with schizophrenia who newly received homecare CM intervention (n = 13 317) between January 1, 2001, and December 31, 2015; their data were derived from Taiwan's National Health Insurance Research Database. We calculated the incidence rate of suicide methods. We examined the demographic and medical utilization profile for suicide and then performed a nested case-control study and multivariate regression to identify independent risk factors for suicide mortality. Among the 13 317 patients who received homecare CM intervention, 1766 died during the study period, of whom 213 died by suicide, which is the leading cause of unnatural death. Jumping from a high place, self-poisoning, and hanging were the top 3 suicide methods. Increased medical utilization was noted for both psychiatric and non-psychiatric services within 3 months of suicide mortality. Comorbidities of depressive disorder, nonspecific heart diseases, pneumonia, and gastrointestinal ulcers were identified as independent risk factors for suicide mortality. Suicide was the leading cause of unnatural mortality in patients with schizophrenia receiving homecare CM intervention in Taiwan. We noted the preferred suicide methods, high medical utilization, and comorbidities before suicide. Thus, we suggest that the CM team should assess lethal methods for suicide and ensure that patients adhere to psychiatry treatment for improving the current care model for this specified population.

Long-Acting Injectable Second-Generation Antipsychotics in Seriously Ill Patients with Schizophrenia: Doses, Plasma Levels, and Treatment Outcomes

This research studies the dose-plasma level (PL) relationship of second-generation antipsychotics, together with the treatment outcomes achieved, in seriously ill people with schizophrenia. An observational, prospective, one-year follow-up study was carried out with patients (N = 68) with severe schizophrenia treated with paliperidone three-month (PP3M) or aripiprazole one-month (ARIM). Participants were divided into standard-dose or high-dose groups. PLs were divided into "standard PL" and "high PL" (above the therapeutic reference range, TRR) groups. The dose/PL relationship, and severity, hospitalizations, tolerability, compliance, and their relationship with doses and PLs were evaluated. There was no clear linear relationship between ARIM or PP3M doses and the PLs achieved. In half of the subjects, standard doses reached PLs above the TRR. The improvements in clinical outcomes (decrease in clinical severity and relapses) were related to high PLs, without worse treatment tolerability or adherence. All participants remained in the study, regardless of dose or PL. Clinical severity and hospitalizations decreased significantly more in those patients with high PLs. Considering the non-linear dose-PL relationship of ARIM and PP3M in people with severe schizophrenia, PLs above the TRR are linked to better treatment outcomes, without worse tolerability. The need in a notable number of cases for high doses to reach those effective PLs is highlighted.

Plasmatic Levels and Response to Variable Doses of Monthly Aripiprazole and Three-Month Paliperidone in Patients with Severe Schizophrenia. Treatment Adherence, Effectiveness, Tolerability, and Safety

Introduction

There is a need when optimizing antipsychotic treatment to know the plasmatic levels (PLs) achieved with the different doses and their relationship with effectiveness and toxicity, especially in patients with poor clinical progress. This study investigates the dose-PL-response relationship of monthly aripiprazole (AOM) and three-month paliperidone (PP3M).

Methods

Observational, 52-week prospective study of patients with severe schizophrenia (CGI-S ≥ 5) treated with PP3M or AOM for at least one year before their inclusion in the study (N=68). Dose-PL relationship was determined. Subjects were included in standard-dose and high-dose (above labeled) and standard/therapeutic range-PLs and high-PLs (above range) groups. Treatment adherence, effectiveness (hospitalizations, severity), tolerability and safety were assessed. PLs and clinical response were evaluated.

Results

No clear linear relationship was found between doses and PLs. In a considerable number of cases, standard doses achieved PLs above the therapeutic range. A significant clinical improvement was related to high PLs, without less safety, tolerability, or treatment compliance being involved. Clinical severity decreased more frequently in patients who received high doses and reached high PLs. Hospital admissions decreased significantly in those patients with high PLs.

Conclusion

Taking into account the absence of a linear relationship between doses and PLs, the effectiveness in people with severe schizophrenia of AOM and PP3M depends on reaching high PLs, achieved with high doses, but also with standard doses in some cases, without leading to worse treatment tolerability, safety, or adherence.

Influencing factors of medication adherence in schizophrenic patients: a meta-analysis

Medication adherence of schizophrenic patients is a growing public health problem. We conducted a meta-analysis on the influencing factors of medication compliance in schizophrenic patients. We searched PubMed, Embase, Cochrane Library, and Web Of Science for relevant articles published up to December 22, 2022. Combined odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess influencing factors. Egger's test, funnel plot, the trim and fill method, and meta-regression analysis were used to assess publication bias. A total of 20 articles were included in the analysis. Twenty influencing factors were divided into seven categories: drug factors (OR = 1.96, 95% CI: 1.48-2.59), problem behavior (OR = 1.77, 95% CI: 1.43-2.19), income and quality of life (OR = 1.23, 95% CI: 1.08-1.39), personal characteristics (OR = 1.21, 95% CI: 1.14-1.30), disease factors (OR = 1.14, 95% CI: 1.98-1.21), support level (OR = 0.54, 95% CI: 0.42-0.70), and positive attitude and behavior (OR = 0.52, 95% CI: 0.45-0.62). This meta-analysis found that drug factors, disease factors, problem behavior, low income and quality of life, and factors related to personal characteristics appear to be risk factors for medication adherence in people with schizophrenia. And support level, positive attitude and behavior appear to be protective factors.

Suicide rates among people with serious mental illness: a systematic review and meta-analysis

BACKGROUND

People with serious mental illness are at great risk of suicide, but little is known about the suicide rates among this population. We aimed to quantify the suicide rates among people with serious mental illness (bipolar disorder, major depression, or schizophrenia).

METHODS

PubMed and Web of Science were searched to identify studies published from 1 January 1975 to 10 December 2020. We assessed English-language studies for the suicide rates among people with serious mental illness. Random-effects meta-analysis was used. Changes in follow-up time and the suicide rates were presented by a locally weighted scatter-plot smoothing (LOESS) curve. Suicide rate ratio was estimated for assessments of difference in suicide rate by sex.

RESULTS

Of 5014 identified studies, 41 were included in this analysis. The pooled suicide rate was 312.8 per 100 000 person-years (95% CI 230.3-406.8). Europe was reported to have the highest pooled suicide rate of 335.2 per 100 000 person-years (95% CI 261.5-417.6). Major depression had the highest suicide rate of 534.3 per 100 000 person-years (95% CI 30.4-1448.7). There is a downward trend in suicide rate estimates over follow-up time. Excess risk of suicide in males was found [1.90 (95% CI 1.60-2.25)]. The most common suicide method was poisoning [21.9 per 100 000 person-years (95% CI 3.7-50.4)].

CONCLUSIONS

The suicide rates among people with serious mental illness were high, highlighting the requirements for increasing psychological assessment and monitoring. Further study should focus on region and age differences in suicide among this population.

The Use of Second-Generation Antipsychotics in Patients with Severe Schizophrenia in the Real World: The Role of the Route of Administration and Dosage-A 5-Year Follow-Up

To assess the impact of the route of administration and doses of second-generation antipsychotics (SGAs) on treatment adherence, hospital admissions, and suicidal behaviour in patients with severe schizophrenia (Clinical Global Impression−Severity−CGI-S ≥ 5), we implemented an observational 5-year follow-up study. A total of 37.5% of the patients on oral antipsychotics (Aps) and 11.5% of those on long-acting injectables (LAIs) abandoned the treatment (p < 0.001). There were no differences in treatment discontinuation between the LAI-AP standard and high-dose groups. A total of 28.1% of the patients on oral Aps had at least one hospitalisation, as well as 13.1% of patients on LAIs (p < 0.001). There were fewer hospitalisations of patients on LAIs in the high-dose group (p < 0.05). Suicide attempts were recorded for 18% of patients on oral Aps but only for 4.6% of patients on LAIs (p < 0.001). No differences were found between the dosage groups on LAIs. Tolerability was good for all Aps and somewhat better for LAIs than oral Aps in terms of side effects (p < 0.05). There were no differences between the standard and high-dose groups. More patients discontinued treatment due to side effects in the oral AP group (p < 0.01). LAI SGA treatment was more effective than oral AP in terms of adherence and treatment outcomes for managing people with severe schizophrenia. Moreover, significant improvements were found that favour high-dose LAI SGA treatment for some of these patients. This study highlights the need to consider LAI antipsychotics and high-dose strategies for patients with severe schizophrenia.

Predictors of Satisfaction with Care in Patients Suffering from Schizophrenia Treated Under Community Mental Health Teams

The aim of this study was to assess satisfaction with care and to identify the predictors of this variable among sociodemographic, clinical and social data in a group of patients suffering from schizophrenia under treatment in community mental health teams. The study included 90 patients with a diagnosis of schizophrenia under the care of community mental health teams. Positive and Negative SyndromeScale, Verona Service Satisfaction Scale, Disability Assessment Schedule, Social Network Index and a loneliness scale (UCLA Loneliness Scale)were used in the study. Prognostic factors for higher satisfaction with care in the multivariate model involved: level of disability (Beta = -0.46, p < 0.001), duration of treatment under a CMHT (Beta = 0.36, p < 0.001), age (Beta = -0.37,p < 0.001), and education (Beta = -0.30, p = 0.002). The model explained 43% of the variance in the dependent variable. 1.Satisfaction with care in a CMHT was high. 2. Higher patient satisfaction could be predicted based on a lower level of disability, longer duration of treatment under a CMHT, lower age and lower education.

Effectiveness of More Personalized, Case-Managed, and Multicomponent Treatment for Patients with Severe Schizophrenia Compared to the Standard Treatment: A Ten-Year Follow-Up

Case management is a model of personalized intervention in people with severe mental illness. To explore the treatment adherence and effectiveness of patients with severe schizophrenia (Clinical Global Impression Severity, CGI-S ≥ 5) undergoing treatment in a community-based, case-managed program (CMP) with an integrated pharmacological and psychosocial approach compared with the standard treatment, an observational, ten-year follow-up study was conducted on patients treated in mental health units (MHUs) or a CMP (n = 688). Treatment discontinuation, hospitalizations, suicide attempts, and antipsychotic (AP) medications were recorded. Clinical severity was assessed with the CGI-S. Adherence to the CMP was higher than adherence to standard treatment (p < 0.001). There were fewer hospitalizations and suicide attempts in the CMP (p < 0.001). The clinical severity decreased more in the CMP (p < 0.005). Long-acting injectable (LAI) antipsychotic medication was more closely related to these outcomes than oral antipsychotics (APs) were (p < 0.001). Patients with severe schizophrenia in an integrated CMP recorded higher treatment compliance and better outcomes compared with standard care. Treatment with LAI APs was linked to these outcomes. A personalized combination of case management and LAI AP medication was more effective in these patients than standard treatment and oral APs.

The mental health nurse as case manager of a patient with severe schizophrenia

Community-based programmes for people with severe mental illness (SMI), with a case management methodology, have shown high treatment adherence and a decrease in psychiatric hospitalizations. There is a need for continuity of care through a good therapeutic relationship, maintained throughout the care process until reaching clinical stabilization. The proposed case shows the treatment of a woman with a diagnosis of schizophrenia who began treatment in a mental health centre and was later referred to a case managed SMI programme. A nursing assessment was carried out from the beginning and a care plan was made based on the NANDA (North American Nursing Diagnosis Association), NOC (Nursing Outcomes Classification), NIC (Nursing Interventions Classification) taxonomy. The outcomes over the years are remarkable, achieving among other objectives not only clinical stabilization but also a normal life.

Psychosocial and Pharmacological Approaches for Improving Treatment Adherence and Outcomes in People With Severe Schizophrenia: A 10-Year Follow-up

The objective of this study was to understand the psychosocial and pharmacological approaches linked to better treatment adherence and outcomes (psychiatric hospitalizations, clinical severity, and suicide attempts) among patients with schizophrenia receiving the standard treatment in mental health units (MHUs) compared with patients in a community-based, case-managed program (CMP). An observational, prospective (10 y) study was conducted involving patients with severe schizophrenia (N=688). The treatment adherence of patients in the CMP was higher than among those in the MHUs (12.2% vs. 84.3% abandoning treatment; P<0.0001). Hospital admissions and suicide attempts were significantly lower among those treated in the CMP than among those receiving standard care in the MHUs (P<0.001). Scores on the clinical severity scale decreased significantly more in the group in the CMP than in the group in the MHUs (P<0.005). Treatment with long-acting injectable antipsychotic medication was closely linked with higher treatment retention (P<0.001) and fewer hospital admissions and suicide attempts compared with treatment with oral antipsychotics in both patient groups, with the effect greater in the group in the CMP (P<0.001). We highlight how patients with severe schizophrenia treated in a CMP with integrated treatment showed a higher retention rate, fewer psychiatric hospital admissions and suicide attempts, and less clinical severity compared with those receiving standard treatment in MHUs. Treatment with long-acting antipsychotics was also clearly related to these outcomes. A combination of intensive case-managed integrated treatment and treatment with long-acting antipsychotic medication facilitated the achievement of clinical and rehabilitation goals in patients with schizophrenia with severe symptoms and impairment compared with standard care and treatment with oral antipsychotics.

Adherence, Tolerability and Effective Doses of Aripiprazole Once-monthly in the Long-term Treatment of Patients with Severe Schizophrenia

BACKGROUND

The evaluation of long-term effectiveness and tolerability of Aripiprazole Once-monthly (AOM) is yet scarce, and severely ill patients have not been specifically studied.

OBJECTIVE

The aim of the study was to explore the long-term adherence, effectiveness and tolerability of AOM in the treatment of patients with severe (Clinical Global Impression-Severity, CGI-S ≥ 5) schizophrenia, and whether high-dose therapy may benefit patients inadequately controlled on standard doses.

METHOD

Six-year mirror-image study, with 36-month prospective follow-up, was conducted on patients with severe schizophrenia who underwent treatment with AOM (n = 60). Assessment included the CGI-S, the WHO Disability Assessment Schedule (WHO-DAS), the Medication Adherence Report Scale (MARS), laboratory tests, and weight and adverse effects reported. Reasons for treatment discontinuation, hospital admissions and psychiatric medications in the previous three years and during the follow-up were recorded.

RESULTS

The average dose was found to be 780 (120) mg/28 days. Tolerability was good, with few side effects or biological parameters alterations reported. There were three discharges due to adverse effects, two due to lack of effectiveness and one treatment abandoning. Weight and prolactin levels were found to be decreased. CGI-S and WHO-DAS decreased (p < 0.001), and MARS increased (p < 0.001). There were less treatment abandoning, hospital admissions (p < 0.0001) and concomitant medication (p<0.01) than during the previous 36 months.

CONCLUSION

Treatment adherence and tolerability of AOM were found to be remarkable, even in those patients on high doses. AOM showed effectiveness in patients with severe schizophrenia, who recorded less hospitalizations and clinical severity and disability, although a considerable percentage of them needed higher doses than labeled.

Hospitalization Rates and Therapy Costs of German Schizophrenia Patients Who are Initiated on Long-Acting Injectable Medication: A Mirror-Image Study

Background

Long-acting injectable (LAI) antipsychotics can reduce relapse, hospitalization, and costs in patients with schizophrenia. However, real-world evidence assessing the impact of treatment with LAIs in Germany is limited.

Objective

To provide updated evidence on the impact of LAI initiation on hospitalization rates and therapy costs.

Methods

Using a mirror-image design, claims data of 850 German patients with schizophrenia who initiated treatment with LAIs during 2013–2015 was retrospectively analyzed. For the included patients, costs and resource utilization were compared for the 12 months before the index date (first initiation of LAI) and the 12 months after the index date. Annual treatment costs, hospitalization rates, ambulatory visits, sick leaves and medical aids were assessed. Two models were used to evaluate hospitalization and its costs. In model 1, hospitalization during the index date (first LAI prescription in 2013–2015) was allocated to the “pre-” time interval, while in model 2 it was neither attributed to the pre- nor to the post-index date. Regression analysis was performed to identify patients who benefited the most in terms of cost reduction from LAI initiation.

Results

Medication costs were significantly higher post-switching to LAI compared with pre-switching period (€3832 vs €799; p < 0.001). In model 1, number of hospitalizations, days hospitalized, and associated costs were significantly lower post-switching compared with pre-switching (2.3 vs 2.6; 59.2 vs 73.4; and €5355 vs €11,908, respectively; all p < 0.001). Similar results were obtained for costs in model 2 (€5355 vs €10,276; p < 0.001). Mean total costs reduced significantly from pre-switching to post-switching period in model 1 (€13,776 vs €10,418; p < 0.001). Patients with characteristics such as higher number of non-psychiatric and psychiatric inpatient stays during the pre-index period (all p < 0.05) benefited the most from cost reduction after LAI initiation.

Conclusion

In this cohort of German patients with schizophrenia, treatment initiation with LAI resulted in reduced hospitalization rates and total costs.
