Final answer:
The idea that patient insurance is a core element of the master patient index is false, as the index focuses on demographic and identifying information. Medicare offers insurance primarily to those over sixty-five, and a positive correlation doesn't always mean health benefits.
Step-by-step explanation:
The statement that a core element of the master patient index is the patient's insurance is false. A master patient index typically includes fundamental demographic information about a patient, such as the patient's name, date of birth, gender, address, contact information, and unique identifiers like medical record numbers, but not necessarily their insurance information.
In reference to the comparative health and medicine question, Medicare is the public healthcare system that offers insurance primarily to people over sixty-five years old. Additionally, a positive correlation does not inherently imply health benefits; it merely indicates a relationship where, as one variable increases, so does the other. Lastly, one goal of Obamacare (the Patient Protection and Affordable Care Act) was indeed to provide all Americans with access to affordable health insurance.
