As the light of the day grows shorter, and a bit more yellow, one can sense both the coming of fall and winter and the migrations that these changes invoke. Not the vast herds of the Serengeti, but the movement of many humans from what will become the increasingly cold North to the welcoming arms of southern climes – Snowbirds. With increasing stress by CMS for physicians and health systems to coordinate and be accountable for a patient's care, migratory patients are out of their control so understanding how they use health services in their winter homes is an increasing concern. A study published in Population Health Management begins to uncover what health resources they use.
