The correlation between the quality of life and clinical variables among outpatients with schizophrenia

Influence of mental health service provision on the perceived quality of life among psychiatric outpatients: associations and mediating factors

Objective

To investigate the relationship between perceived mental health service provision and quality of life (QoL) as perceived by patients in psychiatric outpatient care.

Methods

A total of 373 adult patients registered at 15 psychiatric outpatient clinics in three regions in central and southern Sweden were included in the study. Survey data were collected using a questionnaire on mental health service provision, symptom severity, recovery, clinical diagnosis, sociodemographics (serving as independent variables) and QoL (serving as the dependent variable). Three aspects of mental health service provision were used: patients’ perceived quality of care, perceived staff-patient interaction, and patient reported psychiatric treatments. Structural equation modelling was used to model the relationship among the variables.

Results

Variables in mental health service provision showed few direct associations with patients’ perceived QoL. Instead, the associations of mental health service provision on QoL were mainly mediated through symptom severity and recovery. These relationships were retained after adjusting for sociodemographic variables and clinical diagnoses. The final model achieved excellent goodness of fit (χ2 = 49.502, p = 0.230, RMSEA = 0.020, CFI = 0.997 and a SRMR = 0.024).

Conclusion

This study shows that mental health service provision is associated with patients’ perceived QoL; however, this association is mostly indirect and mediated by reduced symptom severity and increased recovery. This finding can help inform the design of future interventions to enhance service provision to improve patients’ QoL.

The Impact of Health Education on the Quality of Life of Patients Hospitalized in Forensic Psychiatry Wards

PURPOSE

An original health education program, developed for a group of patients of forensic psychiatry wards, was the basis for conducting a study on the impact of educational influences on the quality of life of patients long-term isolated from their natural environment. The main aim of the study was to answer the question: Does health education affect the quality of life of patients in forensic psychiatry wards and is educational activity effective?

METHODS

The study was conducted at the State Hospital for Mental and Nervous Diseases in Rybnik, Poland, in the forensic psychiatry wards, and lasted from December 2019 to May 2020. During the study, patients gained knowledge in the field of broadly understood health education. The study group consisted of 67 men, aged 22-73, diagnosed with schizophrenia. The method of double measurements (before and after the health education cycle) was applied, using the WHOQOL-BREF scale of quality of life and the first author's questionnaire of patients' knowledge, from the educational program used.

RESULTS

Health education does not significantly affect the overall quality of life of patients staying in forensic psychiatry wards, but it does affect their somatic condition. The proprietary health education program is effective because the patients' knowledge has significantly improved.

CONCLUSIONS

The quality of life of interned patients with schizophrenia is not significantly related to educational activities, however, psychiatric rehabilitation through educational activities effectively increases the level of patients' knowledge.

Is change over time in psychotic symptoms related to social functioning?

OBJECTIVE

In psychosis, treatment often focuses on symptom reduction whereas social functioning is also essential. In this study, we investigate positive psychotic symptoms and medication use in relation to social functioning over a 3-year time-period in 531 patients diagnosed with psychosis. Furthermore, relations of positive symptoms with needs for care and quality of life were also investigated.

METHOD

Using repeated measures analysis, changes were measured over time. Hereafter, mixed model analyses were performed to determine the associations of social functioning, needs for care, and quality of life with psychotic symptoms and patient characteristics. Finally, we assessed differences in symptoms and medication dose between those with an increase and those with a decrease in social functioning.

RESULTS

Patients significantly improved in social functioning, while psychotic symptoms increased. Improvement in social functioning was associated with younger age, higher IQ, and lower social functioning at T1, but not with positive symptoms. Also, improvement in social functioning was found to be related to a decrease in the dose of clozapine. Improvement in social functioning occurs despite worsening of positive symptoms.

CONCLUSIONS

The findings suggest the need to further explore the relation between symptomatology, social functioning, and medication use. In the treatment of psychotic disorders, one should reconsider the strong focus on reducing psychotic symptoms. The current focus needs to shift much more toward improving functional outcome, especially when the patient expresses a desire for change in this respect.

Real-world clinical and cost-effectiveness of community clozapine initiation: mirror cohort study

BACKGROUND

Clozapine is the only drug licensed for treatment-resistant schizophrenia (TRS) but the real-world clinical and cost-effectiveness of community initiation of clozapine is unclear.

AIMS

The aim was to assess the feasibility and cost-effectiveness of community initiation of clozapine.

METHOD

This was a naturalistic study of community patients recommended for clozapine treatment.

RESULTS

Of 158 patients recommended for clozapine treatment, 88 (56%) patients agreed to clozapine initiation and, of these, 58 (66%) were successfully established on clozapine. The success rate for community initiation was 65.4%; which was not significantly different from that for in-patient initiation (58.82%, χ²(1,88) = 0.47, P = 0.49). Following clozapine initiation, there was a significant reduction in median out-patient visits over 1 year (from 24.00 (interquartile range (IQR) = 14.00-41.00) to 13.00 visits (IQR = 5.00-24.00), P < 0.001), and 2 years (from 47.50 visits (IQR = 24.75-71.00) to 22.00 (IQR = 11.00-42.00), P < 0.001), and a 74.71% decrease in psychiatric hospital bed days (z = -2.50, P = 0.01). Service-use costs decreased (1 year: -£963/patient (P < 0.001); 2 years: -£1598.10/patient (P < 0.001). Subanalyses for community-only initiation also showed significant cost reductions (1 year: -£827.40/patient (P < 0.001); 2 year: -£1668.50/patient (P < 0.001) relative to costs prior to starting clozapine. Relative to before initiation, symptom severity was improved in patients taking clozapine at discharge (median Positive and Negative Syndrome Scale total score: initial visit: 80 (IQR = 71.00-104.00); discharge visit 50.5 (IQR = 44.75-75.00), P < 0.001) and at 2 year follow-up (Health of Nation Outcome Scales total score median initial visit: 13.00 (IQR = 9.00-15.00); 2 year follow-up: 8.00 (IQR = 3.00-13.00), P = 0.023).

CONCLUSIONS

These findings indicate that community initiation of clozapine is feasible and is associated with significant reductions in costs, service use and symptom severity.

Quality of Life in Patients with Chronic Psychotic Disorders: A Practical Model for Interventions in Romanian Mental Health Centers

Background and Objectives: Current psychiatric care is increasingly focusing on patients' quality of life (QoL). Research is still trying to determine the main factors which influence QoL. The present study aims to assess the QoL of patients with chronic psychotic-spectrum disorders, as well as its relation to symptomatology, functionality, adaptive behavior, and perceived level of recovery. Materials and Methods: The study included a sample of 78 patients with chronic psychosis. Symptomatology and illness severity were assessed with the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression Scale-Severity (CGI-S) scales, respectively. The Global Assessment of Functioning Scale (GAFS) and the Adaptive Behavior Assessment System II (ABAS-II)-Adult Form were used for the assessment of patients' functionality, and the Quality-of-Life Inventory (QOLI) scale was applied for the evaluation of QoL. Results: According to the CGI-Severity scale, 20.5% of the patients were borderline mentally ill, and 24.4% were mildly ill. The highest number of patients (34.6%) were moderately ill, while 14.1% and 2.6% were markedly ill and severely ill, respectively. Among the moderately ill patients, more than half (63%) were patients with schizophrenia, 18.5% were patients with delusional disorder, and 18.5% were patients with schizoaffective disorder. Most of the patients (43.6%) presented moderate functioning deficiency, while 38.5% of the patients presented severe deficiency, according to the GAFS score. When assessed with the ABAS, we observed that almost half of the patients (44.9%) showed an average functioning across skill areas in the conceptual, social, and practical domains. A percent of 67.9% of the patients presented an average QoL, while 15.4% and 12.8% showed a very low and low QoL. QoL was not influenced by the patients' symptomatology, gender, and education level. Having children, family support, better social and conceptual skills, and a higher perceived level of recovery was correlated with an increased QoL, hierarchical multiple regression R2 = 0.379, F(9, 68) = 2.616, and p = 0.012. Conclusions: Psychiatric interventions in psychosis should focus not only on symptoms' control, but also on improving social and family support, as well as adaptive skills to increase the patients' QoL.

Examining relationships between state and trait psychotic symptoms and quality of life in schizophrenia spectrum disorders

Positive and negative symptoms are core aspects of schizophrenia and have been shown to influence patient quality of life (QOL). Previous studies have largely focused on current or state symptoms, with limited work on the contributions of trait symptoms to QOL. This study sought to examine the relationship between both state and trait symptoms and objective and subjective QOL. Fifty-three schizophrenia spectrum disorder patients and 47 healthy controls were recruited. State symptomatology was assessed using the Positive and Negative Syndrome Scale in the patients only. In all participants, trait symptoms were assessed using the Oxford-Liverpool Inventory of Feelings and Experiences, and QOL using Lehman's QOL Interview. Hierarchical linear regression analyses, controlling for depression and neurocognition, revealed that negative state symptoms were related to objective QOL within the patients, while negative trait symptoms were associated with both objective and subjective QOL in patients and healthy controls. No relationships were observed with positive state or trait symptoms and either QOL measure. The findings suggest a degree of complexity in the associations between symptoms and QOL, with primacy for negative symptoms at both state and trait levels. A greater appreciation of trait symptoms may help explain non-complementary QOL changes following symptom remission.

Risk and protective factors of relapse in patients with first-episode schizophrenia from perspectives of health professionals: a qualitative study in northeastern Thailand

Background:  Schizophrenia is a serious mental illness that can relapse after treatments. Risk and protective factors for relapse are dependent on multicultural contexts.

Objective: To identify risk and protective factors related to relapse in first-episode schizophrenia (FES) in northeastern Thailand from perspectives of health professionals.

Methods: This qualitative research collected data from 21 health professional staff members (psychiatric nurses, psychiatrists, psychologists, social workers, occupational therapists and nutritionist) of a tertiary psychiatric hospital of northeastern Thailand who had been involved in mental health care for schizophrenia for at least 5 years by in-depth interviews and group interview using semi-structured interview schedule. Content analyses was used to identify staff perception of factors that put patients at risk of relapse.

Results: Data analyses demonstrated that factors related to relapse in FES patients were drug adherence (drug discontinuation, limited access to new generation drugs, self-dose reduction and skipping medication, and poor insight), family factors (stressful circumstances and family supports), substance abuses (narcotics, addictive substances, caffeinated drinks), concurrent medical illness (insomnia, thyroid diseases, and pregnancy-related hormonal changes), and natural course of disease. 

Conclusion: Factors affecting relapse in FES was not only drug adherence. Family factors, drug abuses, and concurrent health status should be also taken into account. A comprehensive mental health care program should be developed for FES patients in the region.

Knowledge about schizophrenia, insight into illness, and internalized stigma and their associated factors among people diagnosed with schizophrenia in a long-term care facility

PURPOSE

This study assessed the level of knowledge about schizophrenia, insight into illness, and internalized stigma and their associated factors among patients with schizophrenia in Jordan.

DESIGN AND METHODS

A cross-sectional survey was conducted on 135 patients diagnosed with schizophrenia, who had been admitted to the largest psychiatric hospital in Jordan.

FINDINGS

The participants had a low level of knowledge, insight, and a high level of internalized stigma. No correlation was found between these variables. Meanwhile, the educational level and vacation were found to be predictors of knowledge.

PRACTICE IMPLICATIONS

This can help psychiatric nurses to identify which area needs to be improved to ensure the best service and care is provided to patients diagnosed with schizophrenia.

Factors influencing subjective recovery of people with recent-onset psychosis: A cross-sectional study in a low-income sub-Saharan country

People with psychosis were traditionally believed to have a chronic deteriorating condition with no hope of recovery. Recent studies have shown varied levels of recovery across countries. However, evidence from low-income, particularly African countries is scant. This study aimed to investigate levels of subjective recovery of people with recent-onset psychosis and identify its influencing factors. A cross-sectional study was conducted among 263 outpatients with recent-onset psychosis in a low-income country, Ethiopia. Psychiatric outpatients were randomly selected, and assessed by a set of questionnaires measuring their psychosocial, clinical and physical health conditions. Hierarchical multiple regression tests were used to identify factors influencing subjective recovery. The level of subjective recovery was found to be high, with a mean Questionnaire about the Process of Recovery score of 44.17. Individuals with higher quality of life were found to have significantly better subjective recovery level. Hopeless and centrally obese individuals were found to have significantly lower level of subjective recovery. Despite the limitations associated with a cross sectional study design, the results suggest that individuals with recent-onset psychosis in Ethiopia may have a better level of subjective recovery than those in high-income countries and their recovery is influenced by quality of life, hopelessness and central obesity.

Quality of life and its social determinants for patients with schizophrenia and family caregivers in Cambodia

Due to inadequate human and financial resource support, the development of mental health services in Cambodia has been undertaken by various non-governmental organizations (NGOs). Schizophrenia is the most common functional psychotic disorder, causing severe and chronic symptoms, and the programs provided by the NGOs should have enhanced the quality of life (QoL) of patients and their caregivers; however, epidemiological research, which is a driving force behind the recognition of mental health as a global public health concern, is lacking for schizophrenia in Cambodia. This study therefore aimed to create QoL evaluation questionnaires available in Khmer (the Cambodian language) for patients with schizophrenia and family caregivers, and to identify the social determinants and predictors of their QoL. This cross-sectional study recruited 59 patients and 59 caregivers attending three clinics operated by two NGOs: the Transcultural Psychosocial Organization (TPO) Cambodia and the Supporters for Mental Health (SUMH) Cambodia. We conducted linguistic validation of the Schizophrenia Quality of Life Questionnaire 18-item version (S-QoL 18) and the Schizophrenia Caregiver Questionnaire (SCQ), then analyzed correlations between the QoL dimensions and socio-demographic factors. The main findings of this study were as follows: 1) the newly created Khmer versions of S-QoL 18 and SCQ are relatively good psychometric tools that are suitable for research to identify patients’ and caregivers’ needs to improve their QoL; and 2) engaging in paid work or being of the post-Khmer Rouge generation results in higher QoL for patients, but having low household economic status or being affected by chronic disease leads to lower QoL for family caregivers. These findings are useful for enabling community mental health professionals and aid organizations to create programs to lessen the patient and caregiver burden in Cambodia. Further research is necessary to develop practical projects that will improve patients’ and caregivers’ QoL in various clinical settings in Cambodia.

Correlation of Health-Related Quality of Life in Clinically Stable Outpatients with Schizophrenia

BACKGROUND

Generic health-related quality of life (HRQoL) scales are increasingly being used to assess the effects of new treatments in schizophrenia. The objective of this study is to better understand the usefulness of generic and condition specific HRQoL scales in schizophrenia by analyzing their correlates.

METHODS

Data formed part of the Pattern study, an international observational study among 1379 outpatients with schizophrenia. Patients were evaluated with the Mini International Neuropsychiatric Inventory, the Clinical Global Impression-Schizophrenia (CGI-SCH) Scale and the Positive and Negative Syndrome Scale (PANSS) and reported their HRQoL using the Schizophrenia Quality of Life Scale (SQLS), the Short Form-36 (SF-36), and the EuroQol-5 Dimension (EQ-5D). The two summary values of the SF-36 (the Mental Component Score and the Physical Component Score, SF-36 MCS and SF-36 PCS) were calculated.

RESULTS

Higher PANSS positive dimension ratings were associated with worse HRQoL for the SQLS, EQ-5D VAS, SF-36 MCS, and SF-36 PCS. Higher PANSS negative dimension ratings were associated with worse HRQoL for the EQ-5D VAS, SF-36 MCS, and SF-36 PCS, but not for the SQLS or the EQ-5D tariff. PANSS depression ratings were associated with lower HRQoL in all the scales. There was a high correlation between the HRQoL scales. However, in patients with more severe cognitive/disorganized PANSS symptoms, the SQLS score was relatively higher than the EQ-5D tariff and SF-36 PCS scores.

CONCLUSION

This study has shown substantial agreement between three HRQoL scales, being either generic or condition specific. This supports the use of generic HRQoL measures in schizophrenia.
