The study flow chart. The case type codes in outpatient claims were as follows: 61 (home health care [HHC] for patients living at home), 66 (HHC for patients living in nursing homes), 67 (HHC for patients living in long-term care facilities). The therapeutic codes were as follows: tracheostomy care (56004C), insertion or change of the nasogastric tube (47017C), urinal indwelling catheterization (47014C), urinary catheter change (50022C), and stage 3 or 4 pressure sore care (48001C, 48002C, 48003C, 48004C, 48005C). Index date: the date of the 1st day of HHC service was defined as the index date for the HHC subjects; the date of the 1st day of tube or catheter or pressure sore care was defined as the index date for the non-HHC subjects.
