    Create a function that processes patient identification codes in a remote monitoring system by removing every other character from the original code, ensuring simplified yet unique patient tracking. The function should maintain the first character and all even-indexed characters of the identification code, while removing odd-indexed characters to generate a streamlined identifier for the healthcare database.
