Supported Communication Video Training for the Nursing Department in an Inpatient Rehabilitation Hospital.

Only selected items from the Test of Knowledge of Aphasia were used, and using only selected items was not validated. The posttest was done immediately after training, so it did not show whether the gains lasted. There was no control group and no random assignment, so other factors at orientation could have influenced scores. The study did not measure patient communication, patient outcomes, or harm. Participants did not demonstrate the strategies with patients, so staff scores do not show changed behavior. Most participants had less than one year of experience and no prior aphasia training, so results may not apply to experienced staff.

Do not read the staff score gains as proof that patients with aphasia received better or safer care. The study measured nursing staff knowledge and confidence immediately after training, not patient communication or harm.
