Two-step floating catchment area (2SFCA) method
Okay, kiddo, imagine you live in a small town with only one doctor. That doctor is the only one who can help you when you're sick or hurt, so you want to make sure you can get to them easily.
But what if there are other towns nearby, and they all have their own doctors too? How do we know if everyone can get the healthcare they need?
This is where the two-step floating catchment area, or 2sfca, method comes in! It's like a special map that helps us see if people can access the healthcare they need.
First, we draw circles around each doctor's office. The size of the circle depends on how far people can travel to get there – if it's an easy journey, the circle will be bigger.
Then, we look at how many people live in each area that overlaps with a circle. This tells us how many patients each doctor is serving.
But we don't just stop there. What if there are areas that don't have any doctors nearby? We need to make sure people in those areas can still get the help they need.
So we draw extra circles around each of those empty areas, and see which doctor's office is the closest. We count those people too, and add them to the doctor's patient list.
All of this adds up to a big picture of healthcare in the whole region. We can see which doctors are serving the most people, which areas might need more help, and how easy it is for everyone to get the care they need.
And that, my little friend, is the two-step floating catchment area method!
