Assume you are a planner within a large healthcare system in a state that is participating in an expansion of Medicaid coverage. You want to project the demand for healthcare services over the next ten years in the counties in which your healthcare system operates. What data will you need to model demand for healthcare services? Assume that the model you produce projects a significant increase in demand for ambulatory care visits over the next ten years. How should the healthcare system respond to these projections?
Explanation:
To model the demand for healthcare services, a planner would need to collect data on a variety of factors that can affect the demand for healthcare services. These factors could include population demographics (such as age, gender, and income), the prevalence of chronic diseases, the availability and accessibility of healthcare providers and facilities, and trends in healthcare utilization and cost. The planner would also need to collect data on the specific services provided by the healthcare system, such as inpatient and outpatient care, primary care and specialty care, and preventive and acute care.
If the model projects a significant increase in demand for ambulatory care visits over the next ten years, the healthcare system should respond by making plans to increase the availability and accessibility of ambulatory care services. This could involve expanding existing ambulatory care facilities, opening new ambulatory care facilities, or increasing the number of providers who offer ambulatory care services. The healthcare system should also consider implementing strategies to improve the efficiency and effectiveness of ambulatory care services, such as using advanced technologies, implementing team-based care models, and coordinating care across different settings. By taking these steps, the healthcare system can ensure that it is able to meet the projected increase in demand for ambulatory care services.

Viruses are antigenic , meaning that they develop methods to avoid detection by the immune system.
How to describe the two processes by which the influenza virus evolves?When small changes to the surface spikes of the virus allow it to evade detection by the immune system, it is referred to as antigenic drift.
This process can occur quickly in the influenza virus and other RNA viruses because the enzyme required to convert ANA into DNA has low fidelity, meaning it makes many mistakes during replication.
When two different forms of a virus infect the same host cell and viral particles are reassembled into a new form, it is referred to as antigenic shift.
This causes a rapid change in the virus, so the immune system takes longer to respond, meaning it's more likely to cause an outbreak.
