A meta-analysis of ethnic differences in pathways to care at the first episode of psychosis.

OBJECTIVE: We sought to systematically review the literature on ethnic differences in the likelihood of general practitioner (GP) involvement, police involvement, and involuntary admission on the pathway to care of patients with first-episode psychosis (FEP). METHOD: We searched electronic databases and conducted forward and backward tracking to identify relevant studies. We calculated pooled odds ratios (OR) to examine the variation between aggregated ethnic groups in the indicators of the pathway to care. RESULTS: We identified seven studies from Canada and England that looked at ethnic differences in GP involvement (n=7), police involvement (n=7), or involuntary admission (n=5). Aggregated ethnic groups were most often compared. The pooled ORs suggest that Black patients have a decreased likelihood of GP involvement (OR=0.70, 0.57-0.86) and an increased likelihood of police involvement (OR=2.11, 1.67-2.66), relative to White patients. The pooled ORs were not statistically significant for patients with Asian backgrounds (GP involvement OR=1.23, 0.87-1.75; police involvement OR=0.86, 0.57-1.30). There is also evidence to suggest that there may be ethnic differences in the likelihood of involuntary admission; however, effect modification by several sociodemographic factors precluded a pooling of these data. CONCLUSION: Ethnic differences in pathways to care are present at the first episode of psychosis.

A meta-analysis on the efficacy and safety of risperidone in patients with Behavioral and Psychological Symptoms of Dementia (BPSD)

OBJECTIVE: To determine the efficacy and safety of risperidone compared to placebo and haloperidol in the treatment of behavioral and psychological symptoms of dementia. METHODOLOGY: In a systematic review of literature, all articles published from January 1990 - September 2005 that conducted double-blind, randomized controlled clinical trials evaluating the efficacy and safety of risperidone and haloperidol for the treatment of BPSD were selected. The search was performed by means of MEDLINE, PUBMED, Cochrane Library database limited to studies written in English from 1990 to 2005. Key journals and textbooks were also searched in addition to the electronic database search. References mentioned in these studies were likewise reviewed. Two reviewers independently did validity assessment. Analysis of data was done by statistical packs Revman 4.2.7 from Cochrane Collaboration and SPSS (statistical package for the social sciences) v 9.0. RESULTS: Five trials were included in this study. A total of 964 patients were evaluated. Risperidone was superior to placebo as evidenced by significant reduction in the scores of total BEHAVE-AD score (WMD = 2.97, 95% CI = 1.65 - 4.29), BEHAVE-AD aggression subscale (WMD = 1.40, 95% CI = 1.34 - 1.46), and CMAI total aggression subscale (WMD = 3.82, 95% CI = 3.04 - 4.60). Comparison of risperidone and haloperidol showed significant reduction in the total BEHAVE- AD score in patients receiving risperidone (WMD = 1.80, 95% CI = 0.43 - 3.18). Comparing the odds ratio of having an adverse effect, analysis revealed greater chance of developing somnolence (OR = 1.88, 95% CI = 1.27 - 2.77), peripheral edema (OR = 2.43, 95% CI = 1.29 - 4.59) and extrapyramidal symptoms (OR = 1.93, 95% CI = 1.04 - 3.61) with risperidone. CONCLUSION: Risperidone is effective and relatively safe in the treatment of behavioral and psychological symptoms of dementia. Higher incidence of somnolence, peripheral edema and extrapyramidal symptoms was noted with risperidone compared to placebo. Compared with haloperidol, risperidone was superior in the total BEHAVE- AD scale and showed more favorable results in the total CMAI scale, BEHAVE-AD aggression and CMAI total aggression subscales.

Ethnic diversity and pathways to care for a first episode of psychosis in Ontario.

OBJECTIVE: To examine ethnic variations in the pathways to care for persons accessing early intervention (EI) services in Ontario. METHOD: The pathways to care and the duration of untreated psychosis were assessed for first-episode psychosis patients who entered specialized EI services in Ontario. The sample was assigned to the following ethnic classifications: the White (Caucasian), Black (African descent), and Asian (ancestry from the continent) groups, plus all the "other ethnicities" group. RESULTS: There were 200 participants: 78% were male; 61% from the White, 15% Black, 13% Asian, and 11% were from the other ethnicities group. At the first point of contact, more participants used nonmedical contacts (12%), such as clergy and naturopathic healers, than psychologists (8%) or psychiatrists (7%). There were no ethnic differences for duration of untreated psychosis (median 22 weeks) or for initiation of help seeking by family/friends (53%), police (15%), or self (33%). After adjusting for relevant clinical and demographic factors, the Asian and other ethnicities groups were 4 and 3 times (respectively) more likely than the White or Black groups (P = .017) to use emergency room services as the first point of contact in the pathways to care. Participants from the Asian group experienced less involuntary hospitalizations (P = .023) than all the other groups. Yet overall, there were many more similarities than significant differences in the pathways to care. CONCLUSION: EI services should monitor the pathways to care for young people of diverse ethnic backgrounds to address any disparities in accessing care.

A multi-site Canadian perspective: examining the functional outcome from first-episode psychosis.

OBJECTIVE: To examine factors contributing to variance in functional outcome in first-episode psychosis (FEP) following 1 year of treatment. METHOD: Naturalistic 1-year follow-up of a FEP cohort (n = 200), from programs in four university centers in Ontario, Canada. Functional recovery was defined by 'Social and Occupational Functioning Assessment Scale' (SOFAS) score>60. Regression analysis examined the contribution of independent variables to variance in functional outcome. RESULTS: Twelve-month outcome measures were available for 76.5% of the original cohort. Of these, 70% reported being in school/work and in satisfactory relationships. The functional recovery rate was 51%, compared to 74% attaining symptomatic remission. The greatest contributors to variance in outcome were ongoing symptoms at 6 months and substance abuse comorbidity. CONCLUSION: After 1 year of treatment, FEP patients show high rates of symptomatic remission and relatively lower rates of functional recovery. Symptoms and substance abuse contribute to variance in outcome.

The Alumni program: redefining continuity of care in psychiatry.

The Alumni Program is a novel approach to the continuing care and preventive treatment of clients with "chronic" mental illness. This approach demands a different conceptualization of outpatient psychiatric intervention. The infectious disease model has been deliberately replaced with a chronic illness model that more accurately reflects the course and natural history of psychiatric illness. The Alumni Program is similar to the approach employed with other chronic medical conditions like arthritis, asthma, or diabetes. The program has complementary roles for both specialty psychiatric clinicians and family practitioners. In addition, the program empowers clients and their families to play a key role in their own ongoing adaptation and adjustment to chronic illness while striving for optimal wellness.
