Suicide risk in schizophrenia: learning from the past to change the future

Suicide is a major cause of death among patients with schizophrenia. Research indicates that at least 5–13% of schizophrenic patients die by suicide, and it is likely that the higher end of range is the most accurate estimate. There is almost total agreement that the schizophrenic patient who is more likely to commit suicide is young, male, white and never married, with good premorbid function, post-psychotic depression and a history of substance abuse and suicide attempts. Hopelessness, social isolation, hospitalization, deteriorating health after a high level of premorbid functioning, recent loss or rejection, limited external support, and family stress or instability are risk factors for suicide in patients with schizophrenia. Suicidal schizophrenics usually fear further mental deterioration, and they experience either excessive treatment dependence or loss of faith in treatment. Awareness of illness has been reported as a major issue among suicidal schizophrenic patients, yet some researchers argue that insight into the illness does not increase suicide risk. Protective factors play also an important role in assessing suicide risk and should also be carefully evaluated. The neurobiological perspective offers a new approach for understanding self-destructive behavior among patients with schizophrenia and may improve the accuracy of screening schizophrenics for suicide. Although, there is general consensus on the risk factors, accurate knowledge as well as early recognition of patients at risk is still lacking in everyday clinical practice. Better knowledge may help clinicians and caretakers to implement preventive measures.This review paper is the results of a joint effort between researchers in the field of suicide in schizophrenia. Each expert provided a brief essay on one specific aspect of the problem. This is the first attempt to present a consensus report as well as the development of a set of guidelines for reducing suicide risk among schizophenia patients.

Suicidal ideation and suicide attempts among middle-aged and older patients with schizophrenia spectrum disorders and concurrent subsyndromal depression.

This study examines the prevalence and correlates of current suicidal ideation and past suicide attempts among patients aged 40 and older with schizophrenia spectrum disorders and concurrent depressive symptoms. Nearly half the sample (n = 132) reported having attempted suicide once or more in their lifetime; those who had attempted, exhibited greater depression and psychopathology. A regression analysis revealed that only past suicide attempts and hopelessness significantly accounted for the presence of current suicidal ideation. Surprisingly, current suicidal ideation did not differ by diagnosis, race/ethnicity, marital status, living situation, age, education, or severity of medical illness. Overall, suicidal ideation and the presence of past suicide attempts were remarkably prevalent, highlighting the need for continued clinical vigilance with this patient population. The impact of hopelessness and general psychopathology, as well as the insignificance of demographic characteristics and medical illness severity warrant further investigation.

Tri-ethnic variations of co-morbid substance and alcohol use disorders in schizophrenia

OBJECTIVES This study examined the differential prevalence of substance and alcohol use disorders among European Americans, African Americans, and Latinos with schizophrenia (n = 6424) who received public mental health services in San Diego County during fiscal year 2002-2003. METHODS Data were obtained from the public mental health database used by the San Diego County Mental Health System. Chi-Square analyses and stepwise logistic regression analyses were used to examine differences regarding the prevalence of substance and alcohol use among clients with schizophrenia and schizoaffective disorder, and to analyze the sociodemographic variables associated with this co-morbidity. RESULTS Significant differences in the prevalence of diagnosed co-morbidity were found across the ethnic groups. Rates of co-morbid diagnosis among African Americans (25%) were significantly higher than those among European Americans (22%) and Latinos (19%). Logistic regression results revealed ethnicity was a significant predictor of co-morbid substance and alcohol use, as was being homeless and male. Among Latinos, language preference was also a significant predictor. Latinos who denoted English as their primary language were 1.7 times more likely to be diagnosed with co-morbid substance or alcohol use disorders than Latinos who denoted Spanish. CONCLUSIONS Among people with schizophrenia, there were significant differences in prevalence rates and predictors of diagnosed co-morbid substance and alcohol use disorders. Future research is needed to examine the relationship among language preference, level of acculturation, and subsequent diagnosing barriers for Latinos. Among African Americans, the reasons behind increased co-morbidity rates need to be examined, and homelessness should be carefully addressed among all three ethnic groups.

Diagnostic variability for schizophrenia and major depression in a large public mental health care system dataset

Administrative datasets can provide information about mental health treatment in real world settings; however, an important limitation in using these datasets is the uncertainty regarding psychiatric diagnosis. To better understand the psychiatric diagnoses, we investigated the diagnostic variability of schizophrenia and major depression in a large public mental health system. Using schizophrenia and major depression as the two comparison diagnoses, we compared the variability of diagnoses assigned to patients with one recorded diagnosis of schizophrenia or major depression. In addition, for both of these diagnoses, the diagnostic variability was compared across seven types of treatment settings. Statistical analyses were conducted using t tests for continuous data and chi-square tests for categorical data. We found that schizophrenia had greater diagnostic variability than major depression (31% vs. 43%). For both schizophrenia and major depression, variability was significantly higher in jail and the emergency psychiatric unit than in inpatient or outpatient settings. These findings demonstrate that the variability of psychiatric diagnoses recorded in the administrative dataset of a large public mental health system varies by diagnosis and by treatment setting. Further research is needed to clarify the relationship between psychiatric diagnosis, diagnostic variability and treatment setting.

Comparison of International Medical Graduates with US Medical Students and Residents after a Four-Week Course in Palliative Medicine: A Pilot Study

BACKGROUND The need for doctors who have skills in pain management and palliative medicine is greatest in low and moderate resource countries where patients most frequently present to their health care system with advanced illness and greater than 80% of the global deaths occur. While medical students trained in the United States are required to have training in palliative medicine, international medical graduates (IMGs), who have completed medical school outside North America, may not have the same exposure to palliative medicine training as U.S. physicians. The goal of this study was to evaluate whether a four-week course in palliative medicine could bring IMG attitudes, concerns, competence, and knowledge to the level of U.S. trainees. METHODS As part of a prospective cohort study, 21 IMGs from 14 countries participated in a four-week course in palliative medicine. Attitudes, concerns, self-reported competence, and knowledge were assessed pre-course and post-course. The course was evaluated weekly and at the end of the four-week program. The data from the IMGs was compared to data from U.S. medical students and residents using the same assessment tools. RESULTS After the course, IMGs had significantly decreased concern about ethical and legal issues in palliative medicine to the level of U.S.-trained residents and a significant increase in knowledge and self-rated competence equivalent to the level of U.S. trainees. CONCLUSIONS A four-week course in palliative medicine can improve the levels of concern, knowledge and self-assessed competence in IMGs to the level of US trainees.
