Status prior to hospital admission, assessed by nursing intake history from patient or family upon admission to the ICU. In the pre- and post-implementation periods, respectively, data are available as follows: mobility score – 1321 (33%) and 1943 (46%) patients, and activity score – 1337 (34%) and 1968 (47%).
These scores each ranged from 0 to 3, with 1 point assigned if the patient was independent (i.e. not requiring assistance or assistive device) with each of three mobility tasks (bed mobility, bed-to-chair transfer, and ambulation) and activity tasks (dressing or grooming, feeding, and toileting or bathing). For example, a mobility score of 3 means the most independently mobile, while a score of 0 means minimally mobile (unable to even move in bed without assistance). Similarly, an activity score of 3 means the most independent in the activity tasks listed above, while a score of 0 means inability to perform any of the tasks listed above without assistance.
Percentages do not add to 100% due to rounding.
Chi-squared tests were used to compare categorical differences between the pre- and post-implementation periods.
