Substance abuse and the transmission of hepatitis C among persons with severe mental illness.

OBJECTIVES: The authors sought to better understand the relationship of substance abuse to higher rates of transmission of hepatitis C among persons with severe mental illness. METHOD: S: The authors assessed 668 persons with severe mental illness for HIV, hepatitis B, and hepatitis C infection through venipuncture. Demographic characteristics, substance abuse, and risk behaviors for blood-borne infections were assessed through interviews and collection of clinical data. RESULTS: Eighty-two percent of the assessed persons were not infected, and 18 percent had hepatitis C. Among those with hepatitis C infection, 546 (82 percent) tested negative for all viruses. Of the 122 (18 percent) who had hepatitis C, 53 (8 percent) had only hepatitis C, 56 (8 percent) had both hepatitis C and hepatitis B, three (1 percent) had hepatitis C and HIV, and ten (2 percent) had all three infections. More than 20 percent of the sample reported lifetime intravenous drug use, and 14 percent reported lifetime needle sharing. Fifty-seven percent had sniffed of snorted cocaine, and 39 percent had smoked crack. A stepwise regression model was used to identify interaction effects of these behaviors and risk of hepatitis C infection among persons with severe mental illness. Use of needles and of crack cocaine were associated with a large increase in the likelihood of hepatitis C infection. CONCLUSION: S: The high rates of co-occurring substance use disorders among persons with severe mental illness, coupled with the role of substance abuse as the primary vector for hepatitis C transmission, warrants special consideration.

Gender differences in hepatitis C infection and risks among persons with severe mental illness.

OBJECTIVES: The authors assessed gender differences in hepatitis C infection and associated risk behaviors among persons with severe mental illness. METHOD: S: The sample consisted of 777 patients (251 women and 526 men) from four sites. RESULTS: Across sites, the rate of hepatitis C infection among men was nearly twice that among women. Clear differences were noted in hepatitis C risk behaviors. Men had higher rates of lifetime drug-related risk behaviors: needle use (23.1 percent compared with 12.5 percent), needle sharing (17.6 percent compared with 7.7 percent), and crack cocaine use (45.2 percent compared with 30.8 percent). Women had significantly higher rates of lifetime sexual risk behaviors: unprotected sex in exchange for drugs (17.8 percent compared with 11.2 percent), unprotected sex in exchange for money or gifts (30.6 percent compared with 17 percent), unprotected vaginal sex (94 percent compared with 89.7 percent), and anal sex (33.7 percent compared with 22.6 percent). Gender appeared to modify some sex risks. Unprotected sex in exchange for drugs increased the risk of hepatitis C seropositivity for both men and women. In the multivariate model, gender was not significantly associated with hepatitis C seropositivity after adjustment for other risk factors. CONCLUSION: S: Gender differences in the lifetime rates of drug risks explain the higher rates of hepatitis C infection among men with severe mental illness.

Regular sources of medical care among persons with severe mental illness at risk of hepatitis C infection.

OBJECTIVE: An estimated 19.6 percent of persons with severe mental illness are infected with the hepatitis C virus. Given the pressing need to identify and treat persons with severe mental illness who are at risk of hepatitis C infection and transmission, the authors sought to estimate the proportion of hepatitis C-positive and -negative persons with severe mental illness who have a regular source of medical care. METHOD: S: Data for this study were obtained from 777 adults with severe mental illness at four diverse geographic sites at which respondents with severe mental illness participated in a structured interview and laboratory testing for HIV infection, AIDS, hepatitis B infection, and hepatitis C infection. RESULTS: In bivariate analyses, 54.2 percent of hepatitis C-positive and 62.5 percent of hepatitis C-negative study participants with severe mental illness had a regular source of medical care. In multivariate analyses in which potential confounders were statistically controlled for, hepatitis C-positive persons with severe mental illness were less than half as likely as hepatitis C-negative persons to have a regular source of care. Being older, married, insured, or employed or having self-reported health problems increased the likelihood of receiving care. Being black or male or living in a community with high exposure to community violence lowered those odds. CONCLUSION: There is an urgent need to improve access to medical care for persons with severe mental illness, especially those who may be at high risk of or are already infected with the hepatitis C virus.

Editor's introduction: antipsychotic prescribing practices.

This commentary is an introduction to a set of articles reviewing antipsychotic prescribing practices for individuals with schizophrenia, noting where these practice patterns conform to or deviate from evidence-based practice, and identifying the pressing research questions raised by these variations. The delineation of practices supported by the evidence base is crucial for the practical concerns of creating practice guidelines and monitoring performance, as well as for identifying areas where the reach of clinical practice must exceed the grasp of current knowledge. These gaps in knowledge should guide the development of a research agenda that addresses pressing questions commonly confronted in everyday practice. We know from the Schizophrenia Patient Outcomes Research Team (PORT) project and other surveys that clinically significant research findings are not making their way into practice. Additionally, as the articles assembled here indicate, questions of pressing importance in routine practice have yet to make their way into research agendas.

Antipsychotic prescribing practices in Connecticut's public mental health system: rates of changing medications and prescribing styles.

We characterized prescribing in Connecticut's State public mental health system to assess the feasibility of implementing an evidence-based medication algorithm. Medication records for a random sample of outpatients with diagnoses of schizophrenia spectrum disorders showed prescribing patterns similar to the entire United States. The base rate of changing antipsychotic medications was moderate. Over half of patients received decanoate medications, polypharmacy was nontrivial, and there was variability in prescribing patterns across physicians. Caucasian patients were more likely to receive an atypical antipsychotic and less likely to have a decanoate medication, and Latino patients were less likely to change medications. Because the base rate of changing medications was moderate and a considerable proportion of patients were prescribed newer antipsychotic medications, introducing a research-derived medication algorithm with newer atypical antipsychotics as first line agents may fit well with current practice. Further, implementing such an algorithm may reduce racial and ethnic disparities in prescribing patterns.

The Mount Sinai conference on the pharmacotherapy of schizophrenia.

This report summarizes the recommendations from a consensus meeting that focused on specific questions regarding the pharmacotherapy of schizophrenia. The issues were selected because there was evidence that experts had recently disagreed about the evidence supporting a particular practice or when there were substantial variations in a clinical practice indicating that there was disagreement among clinicians. The group of experts was able to reach a consensus regarding the evidence base pertaining to the following issues: First generation (FGAs) and second generation (SGAs) antipsychotics as first line agents; the duration of antipsychotic trials; the effectiveness of clozapine and other agents for treatment refractory schizophrenia; risk of tardive dyskinesia on FGAs and SGAs; differences among antipsychotics for different dimensions of psychopathology; and side effect monitoring for various antipsychotics.

Illness management and recovery: a review of the research.

Illness management is a broad set of strategies designed to help individuals with serious mental illness collaborate with professionals, reduce their susceptibility to the illness, and cope effectively with their symptoms. Recovery occurs when people with mental illness discover, or rediscover, their strengths and abilities for pursuing personal goals and develop a sense of identity that allows them to grow beyond their mental illness. The authors discuss the concept of recovery from psychiatric disorders and then review research on professional-based programs for helping people manage their mental illness. Research on illness management for persons with severe mental illness, including 40 randomized controlled studies, indicates that psychoeducation improves people's knowledge of mental illness; that behavioral tailoring helps people take medication as prescribed; that relapse prevention programs reduce symptom relapses and rehospitalizations; and that coping skills training using cognitive-behavioral techniques reduces the severity and distress of persistent symptoms. The authors discuss the implementation and dissemination of illness management programs from the perspectives of mental health administrators, program directors, people with a psychiatric illness, and family members.

Impact of modifying risk adjustment models on rankings of access to care in the VA mental health report card.

OBJECTIVE: Using a measure from the Veterans Administration (VA) mental health report card, the authors examined stability of report card rankings under different risk adjustment models. The study determined the impact of adding one variable to a standard VA risk adjustment model for access to care and examined whether veterans who reside in counties with VA facilities are more likely than veterans who reside in counties without VA facilities to use VA mental health services. METHODS: The authors compared the proportion of service users among veterans residing in counties either with or without VA facilities; the data were risk-adjusted by using demographic and geographic variables. A variable representing the presence or absence of a VA facility in each county was added to the risk adjustment model, and its impact on regional VA report card rankings for access was calculated. RESULTS: Regional rankings for access to mental health services by all veterans changed substantially when the additional variable was introduced into the risk adjustment model. Seven of 22 regions changed by five or more places. Access to mental health services was higher in counties with VA facilities, even after geographic distance to VA and non-VA hospitals was controlled for. CONCLUSIONS: Caution should be exercised when evaluating performance on the basis of report card rankings alone, even after risk adjustment. The results emphasize the importance of attending to observed and adjusted scores, along with standard deviations and standardized scores, rather than to rank order alone and highlight the need to educate report card users in their interpretation and limitations. County boundaries should be taken into consideration when planning VA mental health services.

The social-environmental context of violent behavior in persons treated for severe mental illness.

OBJECTIVES: This study examined the prevalence and correlates of violent behavior by individuals with severe mental illness. METHODS: Participants (N = 802) were adults with psychotic or major mood disorders receiving inpatient or outpatient services in public mental health systems in 4 states. RESULTS: The 1-year prevalence of serious assaultive behavior was 13%. Three variables-past violent victimization, violence in the surrounding environment, and substance abuse-showed a cumulative association with risk of violent behavior. CONCLUSIONS: Violence among individuals with severe mental illness is related to multiple variables with compounded effects over the life span. Interventions to reduce the risk of violence need to be targeted to specific subgroups with different clusters of problems related to violent behavior.
