    Design a function that processes patient identification codes in a hospital's monitoring system by removing alternate characters to create a simplified cross-reference format. The function should take a patient's full identification code as input and generate a shortened version by eliminating characters at odd-numbered positions (index 1, 3, 5, etc.). This standardized format will be used to match patient records across multiple hospital databases while maintaining data consistency.
