To examine the incidence of cardiometabolic conditions and change in care costs for patients with schizophrenia treated with antipsychotic medications, medical and pharmacy claims from the South Carolina Medicaid program were used to compare the incidence rates for five cardiometabolic conditions in 2,231 patients with schizophrenia who were newly prescribed one of seven antipsychotic medications, using a retrospective cohort design spanning three years. Incidence and cumulative prevalence (pre-existing + incident) rates for the five cardiometabolic conditions were: 10%/23.3% for Type II diabetes mellitus, 7%/13.3% for obesity/excessive weight gain, 17%/20.9% for dyslipidemia, 4.5%/7.3% for high blood pressure, and 15.6%/41.8% for hypertension. After being treated with the antipsychotic medications examined, the odds of developing obesity/excessive weight gain, Type II diabetes mellitus, or dyslipidemia were not significantly related to any specific atypical agent compared to haloperidol. Incidence rates for elevated blood pressure and clinically diagnosed hypertension were higher for patients prescribed ziprasidone (Odds Ratio [OR]=2.41, Confidence Intervals [CI]=1.20-4.85; OR=1.83, CI=1.16-2.90, respectively) relative to those prescribed haloperidol. Cost results indicate significant differences over time in medical service and pharmacy costs in the group which developed incident cardiometabolic conditions. Individuals diagnosed with schizophrenia with moderate prevalence and incidence rates for these cardiometabolic conditions demonstrated substantially decreasing medical care costs over the three years examined, perhaps indicating a widening gap in access to needed services for conditions that are known mortality risk factors.

[Show abstract][Hide abstract] ABSTRACT: Schizophrenia is among the most burdensome and costly illnesses worldwide. To estimate the cost of schizophrenia in France, a longitudinal study was carried out between 1998 and 2002. The main objective of this study was to describe and update the cost of schizophrenia in a longitudinal, representative sample of French patients. The second objective was to identify cost drivers in the treatment of schizophrenia.
Based on a cohort of 288 French schizophrenic patients during 2 years of prospective follow-up, this study collected clinical, patient reported outcomes, quality of life, functioning, patient management, care giver involvement and resource utilisation data every 6 months. For each service, information was collected on the type of service, the frequency of attendance and type of intervention provided to the patient. Unit costs were based on available French databases. Mean service use and costs over the five time points were estimated using between-effects regression models.
In the total sample of 288 patients aged 18-64 years, the mean total cost (€ 3 534) was mainly accounted for by the cost of inpatient treatment (€ 1 390) and day care (€ 1 331). The estimate of the annual cost for direct medical health care for all French schizophrenic patients was € 1 581 million, including € 621 million for inpatient treatment and € 595 million for day care (77%). The costs for medication accounted for 16.1% of total annual costs. The remaining costs (6.9%) included visits to psychiatrists, general practitioners, other physicians and psychologists. The direct resource allocation showed inpatient treatment as the main direct cost. Unemployment was identified as a major indirect cost of schizophrenia treatment. Positive and depressive schizophrenia symptoms at baseline and relapse occurrence during the follow-up period were associated with a higher cost of treatment. Health satisfaction or negative symptoms of schizophrenia at baseline were associated with lower costs.
Several cost drivers were identified. Based on the results obtained in France, we suggest further analysis of mechanisms that influence the service-specific costs for schizophrenia in other areas of the world.

[Show abstract][Hide abstract] ABSTRACT: Since 2003, the U.S. Food and Drug Administration as well as the American Diabetes Association, the American Psychiatric Association, and others have called for routine monitoring of cardiometabolic risk factors for patients of all ages prescribed second-generation antipsychotic medications. This survey of major public and private mental health treatment systems in 2010 found that adherence to such guidelines was limited. The authors describe some of the impediments to widespread monitoring of cardiometabolic risk factors among psychiatric patients taking second-generation antipsychotics and advocate for a nationwide commitment to providing the organizational and financial supports necessary to ensure systematic screening of cardiometabolic health among such patients.
[Show abstract][Hide abstract] ABSTRACT: The objective was to examine hyperlipidemia among Taiwanese patients with schizophrenia.
We obtained a random sample of 766,427 subjects aged ≥18 years in 2005. Subjects with at least one primary diagnosis of schizophrenia and with a primary or secondary diagnosis of hyperlipidemia or medication for hyperlipidemia were identified. We compared the prevalence and incidence of hyperlipidemia in schizophrenic patients with the general population.
The prevalence of hyperlipidemia in patients with schizophrenia was higher than that in the general population (8.15% vs. 8.10%; odds ratio 1.17; 95% confidence interval, 1.04-1.31) in 2005. Compared with the general population, schizophrenic patients had a higher prevalence of hyperlipidemia in individuals aged <50 years, among those with higher insurance amount, and among persons living in northern and central regions and in urban areas. The average annual incidence of hyperlipidemia in schizophrenic patients with second-generation antipsychotic use from 2006 to 2008 was higher than that in the general population (1.57% vs. 1.29%; odds ratio 1.31; 95% confidence interval, 1.11-1.55).
Patients with schizophrenia had a much higher prevalence of hyperlipidemia in young adulthood than that in the general population. Schizophrenic patients with second-generation antipsychotic exposure had a higher incidence of hyperlipidemia than individuals in the general population.
