You need to be sure that your administration team is on board. Your hospital President should be in place no later than 12months, VPs 6-8 months, Adm. assitance 6 months, material manager 6 months,department managers and directors probably 4 months and staff 3 months.
This is pending if you already have a team to assist for orientating, developing policy and procedures, service contracts in place, credentialing approval. Remember everything have to in place before the DOH comes in for your occupancy survey.
Hope this helps for your timeline.
Good Luck.
