In the US healthcare providers, specifically, are booked back-to-back with no breaks except for lunch, which is laughable because we all know treatment care including documentation eats into lunch. This means your provider will not be performing their best (we are not machines of infinite energy), you will likely not be seen on time (with back to back scheduling this is just not feasible), and you will likely have less time and less quality time with your provider. The overworking of providers (physician, nurse, PA, rehab, etc) is leading to burnout so there are less experienced providers available because they leave healthcare. So now, you will also have to wait months to be seen because supply and demand issues.
Primary causes (from my experience): healthcare should have never become a business. Because it is a business, making your workers see as many patients as possible means more money. The biggest problem with this is INSURANCE KEEPS PAYING LESS AND LESS for services provided to the clinics and hospitals (looking at you center for Medicare and Medicaid and all the private insurers who follow these reimbursement cuts). Well now you need to see even more patients to make up to the financial loss and as a worker you will likely not get a raise as well…the shareholders need to keep things profitable. These reimbursement cuts happen year after year. This is driving healthcare to its limit and is part of what is ruining things for all of us.
