RESUMO
BACKGROUND AND OBJECTIVES: There is a critical need for effective interventions to support quality of life for persons living with dementia and their caregivers. Growing evidence supports nonpharmacologic programs that provide care management, disease education, skills training, and support. This cost-benefit analysis examined whether the Care of Persons with Dementia in their Environments (COPE) program achieves cost savings when incorporated into Connecticut's home- and community-based services (HCBS), which are state- and Medicaid-funded. RESEARCH DESIGN AND METHODS: Findings are based on a pragmatic trial where persons living with dementia and their caregiver dyads were randomly assigned to COPE with HCBS, or HCBS alone. Cost measures included those relevant to HCBS decision makers: intervention delivery, health care utilization, caregiver time, formal care, and social services. Data sources included care management records and caregiver report. RESULTS: Per-dyad mean cost savings at 12 months were $2 354 for those who received COPE with a mean difference-in-difference of -$6 667 versus HCBS alone (95% CI: -$15 473, $2 734; not statistically significant). COPE costs would consume 5.6%-11.3% of Connecticut's HCBS annual spending limit, and HCBS cost-sharing requirements align with participants' willingness to pay for COPE. DISCUSSION AND IMPLICATIONS: COPE represents a potentially cost-saving dementia care service that could be financed through existing Connecticut HCBS. HCBS programs represent an important, sustainable payment model for delivering nonpharmacological dementia interventions such as COPE.
RESUMO
Antimicrobial resistance (AMR) poses a serious threat to global public health. However, vaccinations have been largely undervalued as a method to hinder AMR progression. This study examined the AMR impact of increasing pneumococcal conjugate vaccine (PCV) coverage in China. China has one of the world's highest rates of antibiotic use and low PCV coverage. We developed an agent-based DREAMR (Dynamic Representation of the Economics of AMR) model to examine the health and economic benefits of slowing AMR against commonly used antibiotics. We simulated PCV coverage, pneumococcal infections, antibiotic use, and AMR accumulation. Four antibiotics to treat pneumococcal diseases (penicillin, amoxicillin, third-generation cephalosporins, and meropenem) were modeled with antibiotic utilization, pharmacokinetics, and pharmacodynamics factored into predicting AMR accumulation. Three PCV coverage scenarios were simulated over 5 y: 1) status quo with no change in coverage, 2) scaled coverage increase to 99% in 5 y, and 3) accelerated coverage increase to 85% over 2 y followed by 3 y to reach 99% coverage. Compared to the status quo, we found that AMR against penicillin, amoxicillin, and third-generation cephalosporins was significantly reduced by 6.6%, 10.9%, and 9.8% in the scaled scenario and by 10.5%, 17.0%, and 15.4% in the accelerated scenario. Cumulative costs due to AMR, including direct and indirect costs to patients and caretakers, were reduced by $371 million in the scaled and $586 million in the accelerated scenarios compared to the status quo. AMR-reducing benefits of vaccines are essential to quantify in order to drive appropriate investment.
