Best Practice for a reusable task and its output

[Jyotsna Mehta]

What is the best practice to place a task that will be used multiple times across a playbook and the output of this task will be used in the conditionals of the main tasks? I am writing a playbook that 

- does app server patching

- checks the server status and based on the status performs a few tasks

- the checks are performed multiple times within the playbook and the output var is used in the condition for the next task
