Restructure several departments, starting from the Neurology department. Good management starts from making your people comfortable and happy and many workers are willing to leave columbia because of how bad they are treated. Specifically in the Medical Campus.
Columbia is a very big place, run in a very fragmented, feudalistic way. Very hit-or-miss, depending on your individual departmental situation. Many managers are dead weight, holding on for retirement, blocking any possible advancement. In a corporate environment they'd be fired. Work here for a while if you're feeling lazy, then get back to the real world when you feel like having a career again.
Do more thorough research on the activities that are going on daily. Be more involved with small office practices, cross training to save a buck can really harm a patient.
