Access the same Entity via various attributes in DynamoDB

I'll begin by saying I am new to DynamoDB and the world of NoSQL in general. I have a patient entity and I am storing it in a DynamoDB table. My access patterns for the patient entity are: 1. Get patient by id 2. Get patient by first name 3. Get patient by last name 4. Get patient by date of birth 5. Get patient by post code How can I achieve this with my DynamoDB table? Right now, the basic model I've put together is: I'm still in the data modelling phase, so I can ditch that make as many changes as I want.
