The cost reduction in hospitalization associated with paliperidone palmitate in the People's Republic of China, Korea, and Malaysia.

BACKGROUND: Schizophrenia results in substantial health care utilization costs. Much of these costs can be attributed to health care use resulting from nonadherence to treatment, relapse, and hospitalization. AIMS OF THE STUDY: The objective of this research is to further estimate the health care resource utilization costs of patients with schizophrenia in the People's Republic of China, Korea, and Malaysia with a specific focus on the reduction in hospitalization costs associated with the use of long-acting, injectable paliperidone palmitate (PP) relative to alternative treatment medications. METHODS: The study focuses exclusively on the estimated reduction in hospitalization days following treatment with PP and the potential associated cost savings. Cost analysis was done using a payer's perspective and only includes direct health care costs associated with hospitalization. Localized cost data were taken from published sources, and health care utilization was estimated based on a clinical study conducted in countries in the Asia-Pacific region. People's Republic of China, Korea, and Malaysia had the highest number of patients enrolled in the clinical study, and thus were chosen for this research. Analysis looked at 12-month and 18-month periods following initial treatment with PP relative to a retrospective 12-month period utilizing alternative treatment medications. RESULTS: Results suggest that reductions in hospital utilization cost over 12 months may occur through the use of PP relative to alternatives-ranging from $1,991 for the People's Republic of China to $6,698 for Korea and $6,716 for Malaysia. CONCLUSION: Given the substantial costs associated with the treatment of schizophrenia both worldwide and in Asia, it is important to fully understand the costs and outcomes associated with various treatment options. In this research, we have specifically analyzed the direct health care cost savings associated with hospital utilization for patients taking PP relative to alternative treatment methods. The results suggest that reductions in hospital utilization cost were associated with PP treatment, likely largely due to increased adherence to treatment.

The health and economic impact of vaccination with 7-valent pneumococcal vaccine (PCV7) during an annual influenza epidemic and influenza pandemic in China.

BACKGROUND: China has experienced several severe outbreaks of influenza over the past century: 1918, 1957, 1968, and 2009. Influenza itself can be deadly; however, the increase in mortality during an influenza outbreak is also attributable to secondary bacterial infections, specifically pneumococcal disease. Given the history of pandemic outbreaks and the associated morbidity and mortality, we investigated the cost-effectiveness of a PCV7 vaccination program in China from the context of typical and pandemic influenza seasons. METHODS: A decision-analytic model was employed to evaluate the impact of a 7-valent pneumococcal vaccine (PCV7) infant vaccination program on the incidence, mortality, and cost associated with pneumococcal disease during a typical influenza season (15% flu incidence) and influenza pandemic (30% flu incidence) in China. The model incorporated Chinese data where available and included both direct and indirect (herd) effects on the unvaccinated population, assuming a point in time following the initial introduction of the vaccine where the impact of the indirect effects has reached a steady state, approximately seven years following the implementation of the vaccine program. Pneumococcal disease incidence, mortality, and costs were evaluated over a one year time horizon. Healthcare costs were calculated using a payer perspective and included vaccination program costs and direct medical expenditures from pneumococcal disease. RESULTS: The model predicted that routine PCV7 vaccination of infants in China would prevent 5,053,453 cases of pneumococcal disease and 76,714 deaths in a single year during a normal influenza season.The estimated incremental-cost-effectiveness ratios were ¥12,281 (US$1,900) per life-year saved and ¥13,737 (US$2,125) per quality-adjusted-life-year gained. During an influenza pandemic, the model estimated that routine vaccination with PCV7 would prevent 8,469,506 cases of pneumococcal disease and 707,526 deaths, and would be cost-saving. CONCLUSIONS: Routine vaccination with PCV7 in China would be a cost-effective strategy at limiting the negative impact of influenza during a typical influenza season. During an influenza pandemic, the benefit of PCV7 in preventing excess pneumococcal morbidity and mortality renders a PCV7 vaccination program cost-saving.

Estimating the Cost-Effectiveness of the 7-Valent Pneumococcal Conjugate Vaccine in Shanghai, China.

OBJECTIVE: The goal of this study was to analyze the economic benefits of introducing the 7-valent pneumococcal conjugate vaccine (PCV7) into the City Immunity Program in Shanghai. METHODS: A decision-analytic model designed for pneumococcal disease and outcomes of pneumococcal infection was populated with local, age-specific incidence and cost data to estimate the expected economic benefits from vaccinating a birth cohort of 172,183 infants in Shanghai over a 1-year period using a cross-sectional approach. The analysis was assumed to occur in a year at which time the direct and indirect effects of vaccination have reached a steady state. Costs were calculated from a payer perspective and included vaccination program costs and direct medical expenditures from pneumococcal-related disease. RESULTS: The model predicts that 112,629 cases of pneumococcal-related disease could be prevented during a given year following the introduction of the PCV7 vaccine into the City Immunity Program in Shanghai, leading to a reduction of ¥187,923,359 (US $29,067,790) in direct medical costs. Overall, the inclusion of the PCV7 vaccine is estimated to have a cost-per-life-year saved of ¥37,468 (US $5,796) and a cost-per-quality-adjusted-life-year gained of ¥41,603 (US $6,435) when both the direct and indirect effects of the vaccine resulting from herd protection are taken into account. CONCLUSIONS: Results suggest that including PCV7 into the City Immunity Program in Shanghai could be considered cost-effective under generally accepted willingness-to-pay thresholds when both the direct and indirect effects of the vaccine are considered in the analysis.
